Description

Die Erfindung betrifft einen Koaxialverbinder gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a coaxial connector according to the preamble of the claim 1.

Bei derartigen Koaxialverbindern müssen herkömmlicherweise Innenleiter und Außenleiter über eine vorbestimmte Länge entsprechend abisoliert werden, bevor eine kontaktierende Verbindung mit dem Koaxialverbinder selbst hergestellt werden kann. Ferner erfolgt in der Regel die kontaktierende Verbindung des Innenleiters des Koaxialkabels mit einem Innenleiter des Koaxialverbinders beispielsweise durch Löten oder separates Schrauben. Getrennt von dieser Kontaktierung der Innenleiter erfolgt eine Kontaktierung der Hülse des Koaxialverbinders mit dem abisolierten Außenleiter, beispielsweise mit Hilfe einer Crimptechnik, wobei mittels einer Crimpzange eine Hülse des Koaxialverbinders derart zusammengedrückt wird, daß sie in Kontakt mit dem abisolierten Außenleiter kommt.With such coaxial connectors, inner conductors and External conductors are stripped accordingly over a predetermined length before a contacting connection with the coaxial connector itself can. Furthermore, the contacting connection of the inner conductor usually takes place of the coaxial cable with an inner conductor of the coaxial connector, for example by soldering or separate screwing. Separated from this contact the inner conductor makes contact with the sleeve of the coaxial connector with the stripped outer conductor, for example with the aid of a crimping technique, whereby by means of a sleeve of the coaxial connector is pressed together in a crimping tool that it comes into contact with the stripped outer conductor.

Diese Systeme haben jedoch mehrere Nachteile. So ist zum einen das Herstellen der einzelnen Kontakte für Innen- und Außenleiter sehr aufwendig, und es sind Spezialwerkzeuge, wie Lötkolben oder Crimpzangen, notwendig. Ferner sind verschiedene einzelne Hülsen erforderlich, welche vor der Montage des Koaxialverbinders auf das entsprechend abisolierte und vorbereitete Koaxialkabel aufzuschieben sind. Die Montage erfolgt also mit mehreren losen Kleinteilen, welche leicht verlierbar sind. Auch ist es besonders nachteilig, daß insbesondere bei der Crimptechnik das Koaxialkabel deformiert wird. Dies hat besonders starken Einfluß auf eine Impedanz des Koaxialkabels an der gecrimpten Stelle, wobei es durch die Impedanzänderung im Koaxialkabel zu unerwünschten Reflexionen des über das Koaxialkabel laufenden Signals kommt und ferner die Signalweiterleitung in einem derart deformierten Koaxialkabel stark beeinträchtigt ist.However, these systems have several disadvantages. On the one hand, that's how it is made the individual contacts for inner and outer conductors are very complex, and they are Special tools such as soldering irons or crimping pliers are necessary. Furthermore, there are several Individual sleeves are required, which are before the coaxial connector is installed to be pushed onto the appropriately stripped and prepared coaxial cable are. The assembly is done with several loose small parts, which are easily lost. It is also particularly disadvantageous that in particular Crimp technique the coaxial cable is deformed. This has a particularly strong influence to an impedance of the coaxial cable at the crimped location, taking it by the change in impedance in the coaxial cable to unwanted reflections of the comes over the coaxial cable signal and also the signal forwarding is severely impaired in such a deformed coaxial cable.

Aus EP 0 762 545 A2 ist eine Einrichtung zur Verbindung eines Koaxialsteckers mit einem Koaxialkabel bekannt. Hierbei ist eine Kontakthülse vorgesehen, die einerseits Ober ein Gewindeteil in Schraubeingriff mit einem Kabelleiterwellrohr bringbar und andererseits mit einem Steckerkopf des Koaxialsteckers verbindbar ist. Die Anordnung ist derart getroffen, daß die Kontakthülse an ihrem steckerseitigen Ende eine Spannzange mit federnden Spannsegmenten bildet, die eine konisch verlaufende Druckfläche aufweist und von einem hiermit zusammenwirkenden steckerseitig vorgesehenen Druckkegel radial an das Kabelleiterwellrohr anpreßbar ist. Auch diese Anordnung hat den Nachteil, daß der Innenleiter des Koaxialkabels, die Innenleitetisolierung des Koaxialkabels, der Außenleiter des Koaxialkabels und die Außenleiterisolierung des Koaxialkabels in vorbestimmter Weise auf bestimmte Längen geschnitten vorbereitet werden müssen, wobei die Kontakthülse vor dem Einschieben des Koaxialkabels in den Koaxialstecker auf das den Außenleiter bildende Wellrohr des Koaxialkabels aufzuschrauben ist. Gleichzeitig muß die den Kontakt zum Außenleiter herstellende Kontakthülse Haltekräfte zum Halten des Koaxialkabels im Koaxialstecker aufnehmen, wodurch durch wechselnde Zugkräfte am Koaxialkabel der Kontakt zwischen Kontakthülse und dem Außenleiter des Koaxialkabels nicht konstant stabil bleibt, sondern ständigen Veränderungen unterworfen ist. Ferner ist dieses System ausschließlich bei Koaxialkabeln mit Kabelleiterwellrohren als Außen- und Innenleiter verwendbar.EP 0 762 545 A2 describes a device for connecting a coaxial connector known with a coaxial cable. A contact sleeve is provided here on the one hand via a threaded part in screw engagement with a cable conductor corrugated tube bringable and on the other hand connectable to a plug head of the coaxial connector is. The arrangement is such that the contact sleeve on its connector side The end of a collet with resilient clamping segments forms a conical has running pressure surface and of a cooperating with it pressure cone provided on the plug side can be pressed radially onto the corrugated cable conduit is. This arrangement also has the disadvantage that the inner conductor of the coaxial cable, the inner conductor insulation of the coaxial cable, the outer conductor of the coaxial cable and the outer conductor insulation of the coaxial cable in a predetermined manner must be prepared for certain lengths, the Contact sleeve before inserting the coaxial cable into the coaxial connector the corrugated tube of the coaxial cable forming the outer conductor is to be screwed on. At the same time, the contact sleeve making contact with the outer conductor must be Take up holding forces to hold the coaxial cable in the coaxial connector, whereby the contact between the contact sleeve due to changing tensile forces on the coaxial cable and the outer conductor of the coaxial cable does not remain constantly stable, but constant Is subject to change. Furthermore, this system is exclusively at Coaxial cables with cable conductor corrugated tubes can be used as outer and inner conductors.

Zwischen Kabelmantel und Überwurfmutter ist eine mit der Überwurfmutter unverlierbar verbundene, axial geführte Außenleiterkontakthülse vorgesehen, die an ihrem dem Buchseneingang zugewandten Ende mehrere selbstfedernde Zungen aufweist, deren freie Enden zum Kabelmantel hin abgewinkelt sind. Die abgewinkelten Enden der Zungen weisen eine derartige Länge auf und sind bezüglich ihrer räumlichen Lage zum kegelförmigen Buchsenabschnitt derart angeordnet, daß sie beim Zuschrauben der Überwurfmutter infolge der kegelförmigen Verjüngung stetig gegen den Kabelmantel gedrückt werden, diesen durchdringen und schließlich mit dem Außenleiter des Kabels kontaktieren. Das Kabelende wird durch die eingehakten Zungen derart gegen das Kontaktteil gedrückt, daß das herausragende Ende des Kontaktteils zwischen Kabelinnenleiter und der zwischen Kabelinnenleiter und Kabelaußenleiter vorgesehenen Kabelisolierung eindringt und so den Innenleiter des Kabels kontaktiert.DE-OS-1 921 200 describes a coaxial connection device for high-frequency cables known with a socket and a union nut.

At the other end of the socket is a hole-iron-shaped, held in an insulating part trained contact part arranged for receiving the inner cable, which, with its end facing the socket input, makes a difference the insulating part protrudes. There is one between the cable jacket and the union nut the union nut captively connected, axially guided outer conductor contact sleeve provided that several at their end facing the socket input has self-resilient tongues, the free ends of which are angled toward the cable sheath are. The angled ends of the tongues are of such a length on and are in terms of their spatial position to the conical socket section arranged in such a way that when screwing on the union nut the conical taper is pressed continuously against the cable jacket, penetrate this and finally contact with the outer conductor of the cable. The end of the cable is so against the contact part by the hooked tongues pressed that the protruding end of the contact part between the inner cable and the cable insulation provided between the inner cable and outer cable penetrates and thus contacts the inner conductor of the cable.

In einer vorteilhaften Weiterbildung ist das zweite Klemmittel derart angeordnet, daß es sich axial an dem ersten Kontaktmittel abstützt.In one embodiment of the invention, the first contact means is arranged in such a way that that it is supported axially on the union nut. In an advantageous Further development, the second clamping means is arranged such that it axially supports the first contact means.

Zweckmäßigerweise ist das erste Kontaktmittel eine Kontakthülse, welche das in den Koaxialverbinder eingeschobene Koaxialkabel radial umgibt, wobei sich in Richtung des Koaxialverbinders eine Kontaktzange mit wenigstens zwei, insbesondere vier, Kontaktlaschen erstreckt. Hierbei ist es von Vorteil, wenn jede Kontaktlasche an einer inneren, dem Koaxialkabel zugewandten Seite wenigstens einen, insbesondere zwei, Kontaktzähne aufweist. In vorteilhafter Weise sind femer wenigstens zwei Kontaktzähne einer Kontaktlasche derart angeordnet, daß in Kontaktstellung des ersten Kontaktmittels wenigstens ein erster Kontaktzahn durch die Mantelisolation hindurch den Außenleiter kontaktiert und wenigstens ein zweiter Kontaktzahn lediglich in die Mantelisolation des Koaxialkabels hineinragt.Advantageously, the first contact means is a contact sleeve, which in radially surrounds the coaxial connector inserted coaxial cable, whereby in Direction of the coaxial connector, a pair of contact pliers with at least two, in particular four, contact tabs extends. It is advantageous here if each contact tab on an inner side facing the coaxial cable at least one, in particular has two, contact teeth. Advantageously, are also at least two contact teeth of a contact tab arranged such that in Contact position of the first contact means at least one first contact tooth contacted the outer conductor through the jacket insulation and at least one second contact tooth only protrudes into the jacket insulation of the coaxial cable.

Ferner ist es besonders vorteilhaft, wenn die Kontaktzähne in axialer Richtung hintereinander angeordnet sind, wobei der erste Kontaktzahn koaxialverbinderseitig angeordnet ist. Das erste Klemmittel ist zweckmäßigerweise eine radial konusförmige Verengung des Koaxialverbinders, an der freie stirnseitige Enden der Kontaktlaschen der Kontaktzange der Kontakthülse beim Befestigen der Überwurfmutter derart anschlagen, daß sich die Kontaktlaschen der Kontaktzange bezüglich des Koaxialkabels radial nach innen in eine Kontaktstellung verbiegen. Zweckmäßigerweise ist die Kontakthülse aus einem Leiter, insbesondere aus einem Metall, gefertigt.Furthermore, it is particularly advantageous if the contact teeth in the axial direction are arranged one behind the other, the first contact tooth on the coaxial connector side is arranged. The first clamping means is expediently a radially conical one Narrowing of the coaxial connector, at the free ends of the Contact tabs of the contact pliers of the contact sleeve when fastening the union nut strike in such a way that the contact tabs of the contact pliers refer bend the coaxial cable radially inwards into a contact position. The contact sleeve is expediently made of a conductor, in particular of a Metal, manufactured.

Diese Ausbildung von erstem Kontaktmittel und erstem Klemmittel stellt eine selbsttätige Kontaktierung beim Befestigen der Überwurfmutter zwischen dem Koaxialverbinder und dem Außenleiter des Koaxialkabels zur Verfügung, da durch eine axiale Bewegung der Überwurfmutter beim deren Befestigen am Koaxialverbinder das erste Kontaktmittel axial in Richtung auf die konusförmige Verengung verschoben wird. Hierdurch werden die Kontaktlaschen der Kontaktzange mit ihren Kontaktzähnen in die Mantelisolation des Koaxialkabels derart gedrückt, daß wenigstens ein erster Kontaktzahn den Außenleiter des Koaxialkabels kontaktiert. Ferner ist eine Entkopplung zwischen Kontaktierfunktion und Haltefunktion für die Kontakthülse gegeben, da der kontaktierende erste Kontaktzahn nicht gleichzeitig mit Haltekräften belastet wird, welche den Kontakt selbst beeinträchtigen würden. Diese Haltekräfte nimmt der axial hinter dem ersten Kontaktzahn angeordnete zweite Kontaktzahn auf, welcher bevorzugt lediglich in die Mantelisolation hinein ragt.This formation of the first contact means and the first clamping means provides one automatic contact when fastening the union nut between the Coaxial connector and the outer conductor of the coaxial cable are available because an axial movement of the union nut when fastening it to the coaxial connector the first contact means axially in the direction of the conical narrowing is moved. As a result, the contact tabs of the contact pliers with their Contact teeth pressed into the jacket insulation of the coaxial cable in such a way that at least a first contact tooth contacts the outer conductor of the coaxial cable. There is also a decoupling between the contacting function and the holding function for the Given the contact sleeve, since the contacting first contact tooth is not simultaneously is loaded with holding forces that would impair the contact itself. These holding forces are taken by the axially arranged behind the first contact tooth second contact tooth, which preferably only into the jacket insulation protrudes.

In einer weiteren Ausführungsform der Erfindung ist das zweite Kontaktmittel ein Innenleiter des Koaxialverbinders, welcher eine kabelseitige Spannzange mit wenigstens zwei Kontaktlaschen aufweist. Der Innenleiter des Koaxialverbinders ist zweckmäßigerweise hohl. Ferner ist die zweite Klemmeinrichtung eine den abisolierten Innenleiter des Koaxialkabels radial umgreifende Innenleiterhülse, wobei an einem dem Innenleiter des Koaxialverbinders zugewandten Ende der Innenleiterhülse ein axialer Schlitz mit sich in Richtung Innenleiter des Koaxialverbinders konisch erweiternder Klemmfläche ausgebildet ist. Hierbei ist der Schlitzdurchmesser kleiner ist als der Außenumfang der Spannzange. Ferner stützt sich zweckmäßigerweise ein von der Konusfläche abgewandtes Ende der Innenleiterhülse an dem ersten Kontaktmittel ab. Die Innenleiterhülse ist aus einem Isolator, insbesondere einem Kunststoff, gefertigt. Zur Aufnahme des abisolierten Innenleiters des Koaxialkabels weist die Innenleiterhülse eine axiale Bohrung auf.In a further embodiment of the invention, the second contact means is one Inner conductor of the coaxial connector, which has a cable-side collet with at least has two contact tabs. The inner conductor of the coaxial connector is expediently hollow. Furthermore, the second clamping device is the stripped Inner conductor of the coaxial cable radially encompassing inner conductor sleeve, with an end of the inner conductor sleeve facing the inner conductor of the coaxial connector an axial slot with conical towards the inner conductor of the coaxial connector expanding clamping surface is formed. Here is the slot diameter is smaller than the outer circumference of the collet. Furthermore, expediently supports an end of the inner conductor sleeve facing away from the conical surface the first contact agent. The inner conductor sleeve is made of an insulator, in particular a plastic. To accommodate the stripped inner conductor of the coaxial cable, the inner conductor sleeve has an axial bore.

Durch diese vorteilhafte Ausbildung des zweiten Kontaktmittels und des zweiten Klemmittels ist eine selbsttätige Kontaktierung der Innenleiter von Koaxialkabel und Koaxialverbinder beim Befestigen der Überwurfmutter zur Verfügung gestellt, da durch eine axiale Bewegung der Überwurfmutter bei deren Befestigen am Koaxialverbinder das erste Kontaktmittel und damit das sich daran abstützende zweite Klemmittel axial in Richtung des Innenleiters des Koaxialverbinders verschoben werden. Hierbei wird der axiale Schlitz unter Mitwirkung der konusartigen Erweiterung auf die Spannzange geschoben und drückt diese radial zusammen. Weitere Arbeitsschritte, wie Löten oder Crimpen, zum Herstellen eines Kontaktes zwischen Innenleiter des Koaxialverbinders und dem abisolierten Innenleiter des Koaxialkabels sind nicht notwendig, wodurch eine einfache Montage des Koaxialverbinders am Koaxialkabel gegeben ist.This advantageous design of the second contact means and the second Clamping means is an automatic contacting of the inner conductors of coaxial cables and coaxial connector provided when fastening the union nut, because by an axial movement of the union nut when fastening it to the coaxial connector the first contact means and thus the second one supported on it Clamping means axially displaced in the direction of the inner conductor of the coaxial connector become. Here, the axial slot with the participation of the cone-like extension pushed onto the collet and compresses it radially. Further Steps such as soldering or crimping to make contact between Inner conductor of the coaxial connector and the stripped inner conductor of the coaxial cable are not necessary, which makes the coaxial connector easy to install is given on the coaxial cable.

Eine Unverlierbarkeit der Überwurfmutter vor der Montage eines Koaxialkabels an den Koaxialverbinder erzielt man in vorteilhafter Weise dadurch, daß in einem vormontierten Zustand des Koaxialverbinders die Kontakt- und Klemmittel in diesem angeordnet sind und ein koaxialverbinderseitiger umlaufender Rand der Überwurfmutter derart eingerollt ist, daß diese einen kleineren Durchmesser aufweist als ein auf dem Koaxialverbinder für die Überwurfmutter angeordnetes Befestigungsmittel.
auf.A captive of the union nut before the assembly of a coaxial cable on the coaxial connector can be achieved in an advantageous manner in that in a preassembled state of the coaxial connector the contact and clamping means are arranged in it and a circumferential edge of the union nut on the coaxial connector side is rolled up in such a way that the latter has a smaller size Diameter has as a fastening means arranged on the coaxial connector for the union nut.
on.

Zweckmäßigerweise ist der Koaxialverbinder ein Koaxialstecker, ein Koaxialwinkelstecker, eine Koaxialbuchse oder eine Koaxialwinkelbuchse .The coaxial connector is expediently a coaxial connector, a coaxial angle connector, a coaxial socket or a coaxial angle socket.

Der in Fig. 1 dargestellte Koaxialverbinder zeigt einen Koaxialwinkelstecker 10. Dieser steht lediglich beispielhaft für einen beliebigen Koaxialverbinder, wie beispielsweise einen Koaxialstecker, eine Koaxialbuchse oder eine Koaxialwinkelbuchse. Dieser Winkelstecker 10 hat ein steckerseitiges Ende 14 und ein kabeleinlaufseitiges Ende 16. Das steckerseitige Ende 14 dient als Stecker, beispielsweise zum Einstecken in eine entsprechende Buchse an einem Anschlußschrank oder auf einer elektronischen Platine. Das kabeleinlaufseitige Ende 16 dient zum Einschieben eines an den Koaxialstecker 10 anzuschließenden, in Fig. 1 nicht dargestellten Koaxialkabels mit einem Innenleiter, einem Außenleiter und einer Mantelisolation. Der Koaxialstecker 10 umfaßt ferner einen steckerseitigen Außenleiter 12 und einen kabeleinlaufseitigen Außenleiter 18. Das steckerseitige Ende 14 umfaßt ein erstes Isolierteil 20, einen Haltering 22, ein zweites Isolierteil 24 und einen Innenleiter 26, welcher aus Gründen einer besseren Veranschaulichung bezüglich einer Achse 28 um 90° gedreht ist. Der Haltering 22 ist optional auf ein Außengewinde 30 am steckerseitigen Außenleiter 12 aufschraubbar und dient beispielsweise als Anschlag bei Verwendung des Koaxialsteckers 10 durch eine Außenwandung beispielsweise eines Anschlußschrankes hindurch.The coaxial connector shown in FIG. 1 shows a coaxial angle plug 10. This is only an example of any coaxial connector, such as a coaxial plug, a coaxial socket or a coaxial angle socket. This angled plug 10 has a plug end 14 and a cable inlet end End 16. The connector end 14 serves as a connector, for example for plugging into a corresponding socket on a connection cabinet or on an electronic circuit board. The cable inlet end 16 serves for Insert one to be connected to the coaxial connector 10, not in FIG. 1 Coaxial cable shown with an inner conductor, an outer conductor and one Sheath insulation. The coaxial connector 10 also includes a connector-side outer conductor 12 and a cable inlet side outer conductor 18. The plug end 14 comprises a first insulating part 20, a retaining ring 22, a second insulating part 24 and an inner conductor 26, which is for the purpose of better illustration is rotated by 90 ° with respect to an axis 28. The retaining ring 22 is optionally on a External thread 30 can be screwed onto the connector-side outer conductor 12 and serves for example as a stop when using the coaxial connector 10 by a The outer wall of, for example, a connection cabinet.

Der Innenleiter 26 ist koaxial zur Achse 28 angeordnet und ragt in einen Hohlraum 32 des kabeleinlaufseitigen Endes 16 des Koaxialwinkelsteckers 10. An dem in den Hohlraum 32 ragenden Ende des Innenleiters 26 ist ein axialer Schlitz 34 ausgebildet. Eine Achse 36 kennzeichnet eine Mittelachse, entlang derer koaxial ein Koaxialkabel in das offene kabeleinlaufseitige Ende 16 des Koaxialwinkelstekkers 10 einschiebbar ist. Entlang dieser Achse 36 verläuft, bei eingeschobenem Koaxialkabel, der Innenleiter des Koaxialkabels und trifft am Schnittpunkt der Achsen 28, 36 auf den Innenleiter 26 des Koaxialwinkelsteckers 10. An dieser Stelle ist der Innenleiter 26 mit einer kreisförmigen Ausnehmung zur Aufnahme des abisolierten Innenleiters des Koaxialkabels versehen. Es sei nochmals darauf hingewiesen, daß in der Darstellung von Fig. 1 der axiale Schlitz 34 und die kreisförmige Ausnehmung 38 nur deshalb zu sehen sind, weil der Innenleiter 26 um 90° um die Achse 28 gedreht ist. Im Montagezustand fluchtet die Ausnehmung 38 mit der Achse 36 und ist koaxial um diese angeordnet.The inner conductor 26 is arranged coaxially to the axis 28 and projects into a cavity 32 of the cable inlet end 16 of the coaxial angle connector 10. At the in The end of the inner conductor 26 protruding from the cavity 32 is an axial slot 34 educated. An axis 36 identifies a central axis along which it is coaxial a coaxial cable into the open end 16 of the coaxial angle connector 10 can be inserted. Runs along this axis 36, with the inserted Coaxial cable, the inner conductor of the coaxial cable and meets at the intersection of the axes 28, 36 on the inner conductor 26 of the coaxial angle connector 10. At this point is the inner conductor 26 with a circular recess for receiving the stripped Provide the inner conductor of the coaxial cable. It should be pointed out again that in the illustration of Fig. 1, the axial slot 34 and the circular Recess 38 can only be seen because the inner conductor 26 by 90 ° the axis 28 is rotated. In the assembled state, the recess 38 is aligned with the Axis 36 and is arranged coaxially around this.

Ebenfalls koaxial zur Achse 36 sind eine Überwurf- bzw. Anpreßmutter 40, eine Kontakthülse 42 und eine Innenleiterhülse 434 vorgesehen. Die Anpreßmutter 40 ist mittels eines Innengewindes 46 auf ein Außengewinde 48 am kabeleinlaufseitigen Ende 16 des Koaxialwinkelsteckers 10 aufschraubbar. Die Kontakthülse 42 ist aus einem elektrisch leitenden Material, beisp. einem Metall, gefertigt und derart ausgebildet, daß sie in elektrisch leitendem Kontakt zum Außenleiter 18 des Koaxialwinkelsteckers 10 steht. Ein koaxialkabelseitiges Ende 50 der Kontakthülse 42 ist derart ausgebildet, daß es an einer Innenfläche 52 der Anpreßmutter 40 anschlägt, so daß bei einer axialen Bewegung in Fig. 1 entlang der Achse 36 nach links beim Aufschrauben der Anpreßmutter 40 auch die Kontakthülse 42 axial nach links verschoben wird.Also coaxial with the axis 36 are a union nut 40, a Contact sleeve 42 and an inner conductor sleeve 434 are provided. The pressure nut 40 is by means of an internal thread 46 on an external thread 48 on the cable inlet side End 16 of the coaxial angle connector 10 can be screwed on. The contact sleeve 42 is made of an electrically conductive material, ex. a metal, made and such trained that they are in electrically conductive contact with the outer conductor 18 of the coaxial angle connector 10 stands. A coaxial cable-side end 50 of the contact sleeve 42 is designed such that it strikes an inner surface 52 of the pressure nut 40, so that with an axial movement in Fig. 1 along the axis 36 after on the left when screwing on the pressure nut 40 also the contact sleeve 42 axially is shifted to the left.

Die Kontakthülse 42 umfaßt eine sich in Steckerrichtung erstreckende Kontaktzange 54, welche durch axiale Schlitze 56 voneinander getrennte Kontaktlaschen 58 mit jeweiligen freien stirnseitigen Enden 60 aufweist. Dadurch ist über den Kontaktzahn 66 und die Kontakthülse 42 ein Kontakt zwischen dem Außenleiter des Koaxialkabels und dem Außenleiter 12, 18 des Koaxialsteckers 10 hergestellt.The contact sleeve 42 comprises a contact pliers extending in the plug direction 54, which are separated by axial slots 56 contact tabs 58 with respective free ends 60. This is about the contact tooth 66 and the contact sleeve 42 a contact between the outer conductor of the coaxial cable and the outer conductor 12, 18 of the coaxial connector 10.

An den stimseitigen Enden 60 der Kontaktlaschen 58 sind abgeschrägte Flächen 62 ausgebildet. Beim axialen Verschieben der Kontakthülse 42 entlang der Achse 36 während des Aufschraubens der Anpreßmutter 40 schlagen diese schrägen Flächen 62 an einer entsprechenden konusartigen Verengung 64 im kabeleinlaufseitigen Ende 16 des Koaxialsteckers 10 an. Durch den Anpreßdruck der Anpreßmutter 40 bei deren Aufschrauben auf das kabeleinlaufseitige Ende 16 des Koaxialsteckers 10 gleiten die Flächen 62, 64 aneinander ab, wodurch die Kontaktlaschen 58 bezüglich der Achse 36 radial nach innen verbogen werden. Dabei bohren sich Kontaktzähne 66 und 68 in eine Mantelisolierung des radial von der Kontakthülse 42 umgebenen Koaxialkabels ein. Durch die hebelartige Ausbildung der Kontaktlaschen 58 legt dabei der Kontaktzahn 66 einen radial nach innen längeren Weg zurück als der axial dahinter liegende Kontaktzahn 68. Durch entsprechende Maßwahl wird hierdurch erreicht, daß der Kontaktzahn 66 durch die Mantelisolierung des Koaxialkabels hindurch bis zum Außenleiter des Koaxialkabels kommt und einen entsprechenden Kontakt herstellt, während gleichzeitig der dahinter liegende Kontaktzahn 68 lediglich in die Mantelisolation des Koaxialkabels eindringt und Haltekräfte für das Koaxialkabel innerhalb des Koaxialsteckers 10 zur Verfügung stellt sowie entsprechende Zug- bzw. Druckbelastungen auf das Koaxialkabel von dem kontaktierenden Kontaktzahn 66 abhält. Auf diese Weise steht die Kontaktfläche zwischen dem Außenleiter des Koaxialkabels und dem Kontaktzahn 66 nicht unter einem wechselnden Druck bzw. einer wechselnden Zugkraft, wodurch dieser Kontakt, einmal hergestellt, konstante elektrische Eigenschaften aufweist. Die Innenleiterhülse 44 ist aus einem isolierenden Material, beispielsweise Kunststoff, gefertigt, wobei deren kabelseitiges Ende 70 derart ausgebildet ist, daß es stimseitig an der Kontakthülse 42 anschlägt. Dadurch wird beim Aufschrauben der Anpreßmutter 40 und einer entsprechenden axialen Bewegung entlang der Achse 36 in Fig. 1 nach links mit der Kontakthülse 42 auch die Innenleiterhülse 44 in der Fig. 1 nach links verschoben.At the front ends 60 of the contact tabs 58 there are beveled surfaces 62 trained. When the contact sleeve 42 is axially displaced along the axis 36 while screwing on the pressure nut 40, these slant Surfaces 62 on a corresponding cone-like constriction 64 in the cable inlet side End 16 of the coaxial connector 10. By the pressure of the pressure nut 40 when screwing them onto the cable inlet end 16 of the Coaxial connector 10 slide the surfaces 62, 64 against one another, as a result of which the contact tabs 58 are bent radially inwards with respect to the axis 36. there drill contact teeth 66 and 68 in a jacket insulation of the radially from the Contact sleeve 42 surrounding coaxial cable. Through the lever-like training the contact tabs 58, the contact tooth 66 places a radially inward longer one Way back than the axially behind contact tooth 68. By appropriate Dimensional choice is achieved in that the contact tooth 66 through the jacket insulation of the coaxial cable through to the outer conductor of the coaxial cable comes and makes a corresponding contact, while at the same time the one behind lying contact tooth 68 only in the jacket insulation of the coaxial cable penetrates and holding forces for the coaxial cable within the coaxial connector 10 provides as well as corresponding tensile or compressive loads on the Prevents coaxial cable from contacting contact tooth 66. In this way is the contact area between the outer conductor of the coaxial cable and the Contact tooth 66 not under a changing pressure or a changing Tensile force, which makes this contact, once made, constant electrical properties having. The inner conductor sleeve 44 is made of an insulating material, for example Plastic, manufactured, the cable-side end 70 formed in this way is that it strikes the contact sleeve 42 at the end. As a result, the Screw on the pressure nut 40 and a corresponding axial movement along the axis 36 in Fig. 1 to the left with the contact sleeve 42, the inner conductor sleeve 44 shifted to the left in FIG. 1.

An einem dem Innenleiter 26 zugewandten Ende 72 der Innenleiterhülse 44 ist ein axialer Schlitz 74 vorgesehen. Dieser Schlitz 74 erweitert sich in Richtung auf das Ende 72 der Innenleiterhülse 44 hin konusartig. In der Darstellung von Fig. 1 ist die Innenleiterhülse 44 um 90° bezüglich der Achse 36 gedreht dargestellt, da ansonsten der axiale Schlitz 74 und die daran anschließende konusartige Erweiterung nicht sichtbar wären. In Montagestellung ist die Innenleiterhülse 44 entsprechend gedreht angeordnet, so daß Anschlagflächen 76 der konusartigen Erweiterung am Ende 72 der Innenleiterhülse 44 dafür sorgen, daß beim Aufschrauben der Anpreßmutter 40 und der daraus resultierenden translatorischen Bewegung der Innenleiterhülse 44 in Fig. 1 entlang der Achse 36 nach links die Innenleiterhülse 44 derart auf das untere Ende des geschlitzten Innenleiters 26 geführt aufgeschoben wird, daß der Innenleiter 26 innerhalb des axialen Schlitzes 74 zu liegen kommt.At one end 72 of the inner conductor sleeve 44 facing the inner conductor 26 there is a axial slot 74 is provided. This slot 74 widens towards that End 72 of the inner conductor sleeve 44 towards the cone. 1 is the inner conductor sleeve 44 is shown rotated by 90 ° with respect to the axis 36, otherwise the axial slot 74 and the subsequent conical extension would not be visible. In the assembly position, the inner conductor sleeve 44 is corresponding arranged rotated so that stop surfaces 76 of the cone-like extension at the end 72 of the inner conductor sleeve 44 ensure that when screwing on the pressure nut 40 and the resulting translational movement the inner conductor sleeve 44 in FIG. 1 along the axis 36 to the left the inner conductor sleeve 44 thus pushed onto the lower end of the slotted inner conductor 26 will be that the inner conductor 26 to lie within the axial slot 74 comes.

Dadurch, daß die Breite des axialen Schlitzes 74 kleiner ist als der Außenumfang des Steckerinnenleiters 26, wird der geschlitzte Abschnitt des Innenleiters 26 durch die Innenleiterhülse 44 zusammengedrückt und kontaktiert dadurch den in der kreisförmigen Ausnehmung 38 bei eingeschobenem Koaxialkabel angeordneten Innenleiter des Koaxialkabels.Because the width of the axial slot 74 is smaller than the outer circumference of the inner conductor 26, the slotted portion of the inner conductor 26 compressed by the inner conductor sleeve 44 and thereby contacts the in the circular recess 38 when the coaxial cable is inserted Inner conductor of the coaxial cable.

Die aufgeschraubte Anpreßmutter 40 stellt eine Haltekraft zur Verfügung, welche sich durch den Anschlag 50 auf die Kontakthülse 42 und durch den Anschlag 70 auf die Innenleiterhülse 44 überträgt. Die jeweiligen Hülsen 42 und 74 setzen diese Haltekraft in eine entsprechende Kontaktkraft am Kontaktzahn 66 bzw. am geschlitzten und zusammengedrückten Teil des Innenleiters 26 im Hohlraum 32 um.The screwed pressure nut 40 provides a holding force which through the stop 50 on the contact sleeve 42 and through the stop 70 transfers to the inner conductor sleeve 44. The respective sleeves 42 and 74 set this Holding force in a corresponding contact force on the contact tooth 66 or on the slotted and compressed part of the inner conductor 26 in the cavity 32.

Wie sich aus der vorangegangenen Beschreibung in Zusammenhang mit Fig. 1 ergibt, erfolgt somit eine selbsttätige Kontaktierung des Innenleiters und des Außenleiters des Koaxialkabels mit dem Außenleiter 18 und dem Innenleiter 26 des Koaxialsteckers 10 einfach durch Festschrauben der Anpreßmutter 40. Weitere Kontaktierungsschritte sind nicht erforderlich.As can be seen from the preceding description in connection with FIG. 1 results in an automatic contacting of the inner conductor and the outer conductor of the coaxial cable with the outer conductor 18 and the inner conductor 26 of the Coaxial connector 10 simply by screwing the pressure nut 40. Others Contacting steps are not necessary.

Vor der Montage des Koaxialsteckers 10 an einem Koaxialkabel wird dieser in folgender Weise vormontiert. In das offene kabeleinlaufseitige Ende 16 des Koaxialsteckers 10 wird zunächst die Innenleiterhülse 44 und anschließend die am Ende 70 der Innenleiterhülse 44 anschlagende Kontakthülse 42 eingeführt. Daraufhin wird die Anpreßmutter 40 lediglich so weit auf das kabeleinlaufseitige Ende 16 des Koaxialsteckers 10 aufgeschraubt, daß ein steckerseitiger umlaufender Rand 78 der Anpreßmutter 40 das Außengewinde 48 des kabeleinlaufseitigen Endes 16 des Koaxialsteckers 10 passiert hat. Danach wird der umlaufende Rand 78 der Anpreßmutter 40 derart eingerollt, daß der Innendurchmesser des umlaufenden Randes 78 kleiner ist als der Außendurchmesser des Außengewindes 48 am kabeleinlaufseitigen Ende 16 des Koaxialsteckers 10. Dadurch ist ein Wiederabschrauben der Anpreßmutter 40 verhindert, und durch den Anschlag des Endes 50 der Kontakthülse 42 an der Anschlagfläche 52 innerhalb der Anpreßmutter 40 werden die Hülsen 42 und 44 innerhalb des Hohlraums 32 des Koaxialsteckers 10 gehalten.Before mounting the coaxial connector 10 on a coaxial cable, this is described in the following Way pre-assembled. In the open cable inlet end 16 of the coaxial connector 10 is first the inner conductor sleeve 44 and then the one at the end 70 of the inner conductor sleeve 44 contact sleeve 42 inserted. thereupon the pressure nut 40 is only so far on the cable inlet end 16 of the Screwed coaxial connector 10 that a connector-side peripheral edge 78th the pressure nut 40, the external thread 48 of the cable inlet end 16 of the coaxial connector 10 has happened. Thereafter, the peripheral edge 78 of the Pressure nut 40 rolled up so that the inner diameter of the circumferential Edge 78 is smaller than the outer diameter of the external thread 48 on the cable inlet side End 16 of the coaxial connector 10. This is a unscrewing the pressure nut 40 prevented, and by the stop of the end 50 of the contact sleeve 42 on the stop surface 52 within the pressure nut 40 the sleeves 42 and 44 within the cavity 32 of the coaxial connector 10th held.

In diesem Zustand wird der Koaxialverbinder 10 an einen Endanwender abgegeben und besteht aus lediglich einem zu handhabenden Teil. Durch ein offenes Ende 80 der Anpreßmutter 40 ist nunmehr ein Koaxialkabel koaxial durch die Anpreßmutter 40, durch die Kontakthülse 42 und mit einer Innenleiterisolierung am Ende 70 der Innenleiterhülse 44 anschlagend einführbar. Hierbei muß das Koaxialkabel vom Endanwender lediglich derart vorbereitet werden, daß der Innenleiter des Koaxialkabels abisoliert ist und über eine vorbestimmte Strecke entlang der Achse 36 frei liegt. Dieser Innenleiter wird beim Einschieben des Koaxialkabels in den Koaxialstecker 10 durch eine axiale Bohrung 82 in der Innenleiterhülse 44 geführt, so daß der Innenleiter innerhalb der kreisförmigen Ausnehmung 38 des Innenleiters 26 des Koaxialsteckers 10 zu liegen kommt. Nachdem das Koaxialkabel in dieser Weise durch die Anpreßmutter 40 und durch die Kontakthülse 42 hindurch eingeführt ist, erfolgt das Festziehen der Anpreßmutter 40 mittels weiteren Aufschraubens auf das Außengewinde 48 des kabeleinlaufseitigen Endes 16 des Koaxialsteckers 10.In this state, the coaxial connector 10 is delivered to an end user and consists of only one part to be handled. With an open end 80 of the pressure nut 40 is now a coaxial cable coaxial through the pressure nut 40, through the contact sleeve 42 and with an inner conductor insulation on Insertable end 70 of the inner conductor sleeve 44. Here, the coaxial cable be prepared by the end user only in such a way that the inner conductor of the coaxial cable is stripped and along a predetermined distance the axis 36 is exposed. This inner conductor becomes when inserting the coaxial cable into the coaxial connector 10 through an axial bore 82 in the inner conductor sleeve 44 out, so that the inner conductor within the circular recess 38th of the inner conductor 26 of the coaxial connector 10 comes to rest. After the coaxial cable in this way through the pressure nut 40 and through the contact sleeve 42 is inserted through, the pressing nut 40 is tightened by means of further screwing onto the external thread 48 of the cable inlet end 16 of the coaxial connector 10.

Durch die aufschraubende Betätigung der Anpreßmutter 40 werden, wie oben näher erläutert, die Hülsen 42 und 44 entsprechend axial zur Achse 36 in Fig. 1 nach links verschoben, und es kommt zu einer entsprechend selbsttätigen Kontaktierung von Innenleiter und Außenleiter des Koaxialkabels. Dies erfordert, wie unmittelbar klar ist, kein besonderes Spezialwerkzeug, und die Verbindung zwischen Koaxialstecker 10 und Koaxialkabel 84 ist in einem einzigen Schritt mit einem einzigen Handgriff ohne zusätzliche Maßnahmen kontaktsicher und dauerhaft hergestellt. Gleichzeitig mit der Kontaktierung erfolgt, wie oben bereits erläutert, mittels der Zähne 68 der Kontakthülse 42 eine entsprechende Fixierung des Koaxialkabels innerhalb des Koaxialsteckers 10 in der Art einer Zugentlastung.By screwing on the pressure nut 40, as described in more detail above explained, the sleeves 42 and 44 corresponding axially to the axis 36 in Fig. 1 after shifted to the left, and there is a corresponding automatic contact of inner conductor and outer conductor of the coaxial cable. This requires, as immediately is clear, no special tool, and the connection between Coaxial connector 10 and coaxial cable 84 is in a single step with a single Handle made contact-safe and durable without additional measures. Simultaneously with the contacting, as already explained above, by means of the teeth 68 of the contact sleeve 42 a corresponding fixation of the coaxial cable within the coaxial connector 10 in the manner of a strain relief.

Fig. 2 zeigt den Koaxialwinkelstecker 10 in vormontiertem Zustand. Die Hülsen 42 und 44 sind in das kabeleinlaufseitige Ende 16 des Koaxialsteckers 10 in der dargestellten Reihenfolge eingeschoben, und zusätzlich ist durch die Öffnung 80 der Anpreßmutter 40 ein Koaxialkabel 84 mit einem Außenleiter 86 und einem Innenleiter 88 und einer Mantelisolierung 90 (Fig. 4) eingeschoben. Die Anpreßmutter 40 ist lediglich so weit auf das kabeleinlaufseitige Ende 16 des Koaxialsteckers 10 aufgeschraubt, daß der umlaufende Rand 78 der Anpreßmutter 40 das Gewinde 48 passiert hat. Wie in Fig. 2 dargestellt, ist der umlaufende Rand 78 eingerollt, so daß die Anpreßmutter 40 nicht mehr abschraubbar ist. Somit hält die Anpreßmutter 40 die beiden Hülsen 42 und 44 innerhalb des Koaxialsteckers 10 in dessen kabeleinlaufseitigem Ende 16.Fig. 2 shows the coaxial angle connector 10 in the preassembled state. The sleeves 42 and 44 are in the cable entry end 16 of the coaxial connector 10 in the illustrated Order inserted, and in addition through the opening 80 is the Pressure nut 40 a coaxial cable 84 with an outer conductor 86 and an inner conductor 88 and a jacket insulation 90 (Fig. 4) inserted. The pressure nut 40 is only so far on the cable inlet end 16 of the coaxial connector 10 screwed that the peripheral edge 78 of the pressure nut 40 the thread 48 happened. As shown in FIG. 2, the peripheral edge 78 is rolled up, see above that the pressure nut 40 can no longer be unscrewed. The pressure nut thus holds 40 the two sleeves 42 and 44 within the coaxial connector 10 in it cable inlet end 16.

Das eingeschobene Koaxialkabel 84 ist lediglich derart vorbereitet, daß der Innenleiter 88 um eine vorbestimmte Strecke abisoliert ist. Weitere Abisolierungen um vorbestimmte Strecken von der Mantelisolierung oder des Dielektrikums 96 (Fig. 6) sind nicht erforderlich.The inserted coaxial cable 84 is only prepared in such a way that the inner conductor 88 is stripped by a predetermined distance. Further stripping by predetermined distances from the jacket insulation or dielectric 96 (Fig. 6) are not required.

Wie insbesondere aus Fig. 3 ersichtlich, ist das Koaxialkabel 84 derart in den Koaxialstecker 10 eingeschoben, daß der Innenleiter 88 in der kreisförmigen Ausnehmung 38 des Innenleiters 26 des Koaxialsteckers 10 zu liegen kommt. Die Innenleiterhülse 44 befindet sich in Bezug auf die Achse 36 in einer axial solchen Position, daß zwei Kontaktlaschen 92 und 94 des Innenleiters 26 nicht zusammengedrückt werden.As can be seen in particular from FIG. 3, the coaxial cable 84 is such in the Coaxial connector 10 inserted that the inner conductor 88 in the circular recess 38 of the inner conductor 26 of the coaxial connector 10 comes to rest. The inner conductor sleeve 44 is located axially with respect to axis 36 Position that two contact tabs 92 and 94 of the inner conductor 26 are not pressed together become.

Fig. 4 veranschaulicht den Zustand des Koaxialsteckers 10 mit Koaxialkabel 84 nach dem Festschrauben der Anpreßmutter 40. Wie sich unmittelbar aus einem Vergleich von Fig. 2 mit 4 ergibt, erfolgt durch das Festschrauben der Anpreßmutter 40 eine axiale Bewegung der Hülsen 42 und 44 entlang der Achse 36 in Fig. 2 und 4 nach links. Dadurch gleitet die abgeschrägte Fläche 62 des stimseitigen Endes 60 der Kontaktlasche 58 der Kontakthülse 42 an der konusartigen Verengung 64 im kabeleinlaufseitigen Ende 16 des Koaxialsteckers 10 ab, wobei die Kontaktlaschen 58 in der in Fig. 4 dargestellten Weise radial nach innen gedrückt werden. Dadurch bohren sich die Kontaktzähne 68 und 66 in die Mantelisolation 90 des Koaxialkabels 84. Durch die hebelartige Ausbildung der Kontaktlaschen 48 und eine entsprechende Wahl der Maße von Koaxialstecker 10 und Hülse 42 schneidet der erste Kontaktzahn 66, wie insbesondere aus Fig. 2 ersichtlich, durch die Mantelisolation 90 hindurch und kontaktiert den Außenleiter 86. Demgegenüber schneidet der zweite Kontaktzahn 68 lediglich in die Mantelisolation 90 und sorgt damit für eine entsprechende Halterung des Koaxialkabels 84 im kabeleinlaufseitigen Ende 16 des Koaxialsteckers 10. Auf diese Weise sind Halte- bzw. Zugkräfte, welche auf das Koaxialkabel 84 wirken, von dem kontaktierenden Kontaktzahn 66 abgehalten, so daß der Kontakt zwischen Kontaktzahn 66 und dem Innenleiter 86 des Koaxialkabels 84 keinen wechselnden Kräften unterworfen ist.4 illustrates the state of the coaxial connector 10 with coaxial cable 84 after tightening the pressure nut 40. How to get out of a Comparison of Fig. 2 with 4 results, is done by screwing the pressure nut 40 an axial movement of the sleeves 42 and 44 along the axis 36 in 2 and 4 to the left. As a result, the beveled surface 62 of the face side slides End 60 of the contact tab 58 of the contact sleeve 42 at the conical constriction 64 in the cable inlet end 16 of the coaxial connector 10, the Contact tabs 58 pressed radially inward in the manner shown in Fig. 4 become. As a result, the contact teeth 68 and 66 drill into the jacket insulation 90 of the coaxial cable 84. The lever-like design of the contact tabs 48 and a corresponding choice of the dimensions of coaxial connector 10 and sleeve 42 the first contact tooth 66 cuts through, as can be seen in particular from FIG. 2 through the jacket insulation 90 and contacts the outer conductor 86. In contrast the second contact tooth 68 only cuts into the jacket insulation 90 and thus ensures a corresponding mounting of the coaxial cable 84 in the cable inlet side End 16 of the coaxial connector 10. In this way, holding or Tensile forces acting on the coaxial cable 84 from the contacting Contact tooth 66 held so that the contact between contact tooth 66 and the inner conductor 86 of the coaxial cable 84 is not subject to changing forces is.

Fig. 5 veranschaulicht den Zustand des unteren Endes des Innenleiters 26 des Koaxialsteckers 10 im Hohlraum 32. Ebenso wie die Kontakthülse 42 wird die Innenleiterhülse 44 beim Festschrauben der Anpreßmutter 40 axial in Fig. 4 nach links entlang der Achse 36 verschoben, so daß die Innenleiterhülse 44 mit ihrem axialen Schlitz 74 über den Innenleiter 26 des Koaxialsteckers 10 gleitet und so die Kontaktlaschen 92 und 94 des Innenleiters 26 des Koaxialsteckers 10 derart zusammendrückt, daß diese den Innenleiter 88 des Koaxialkabels 84 kontaktieren.Fig. 5 illustrates the state of the lower end of the inner conductor 26 of the Coaxial connector 10 in the cavity 32. Like the contact sleeve 42, the inner conductor sleeve 44 after tightening the pressure nut 40 axially in FIG. 4 left along the axis 36 so that the inner conductor sleeve 44 with her axial slot 74 slides over the inner conductor 26 of the coaxial connector 10 and so the contact tabs 92 and 94 of the inner conductor 26 of the coaxial connector 10 such compresses that they contact the inner conductor 88 of the coaxial cable 84.

Durch eine Haltekraft der Anpreßmutter 40 in festgeschraubtem Zustand bleiben die Hülsen 42 und 44 unter entsprechender axialer Krafteinwirkung auf deren jeweilige Anschlagflächen 50 und 70 in ihrer in Fig. 4 dargestellten Position fixiert, wobei die axiale Krafteinwirkung für eine entsprechende Kontaktkraft an den Kontaktstellen zum Außenleiter 86 und Innenleiter 88 des Koaxialkabels 84 sorgt.By holding force of the pressure nut 40 remain in the screwed state the sleeves 42 and 44 with a corresponding axial force on their respective Stop surfaces 50 and 70 fixed in their position shown in FIG. 4, the axial force for a corresponding contact force on the Provides contact points to the outer conductor 86 and inner conductor 88 of the coaxial cable 84.

Wie somit ebenfalls unmittelbar aus Fig. 2 - 6 hervorgeht, erfolgt eine Kontaktierung des Außenleiters 86 und Innenleiters 88 des Koaxialkabels 84 selbsttätig durch einfaches Aufschrauben der Anpreßmutter 40. Hierbei ist klar, daß die Schraubverbindung auch durch eine entsprechend andere Halteverbindung zwischen Anpreßmutter 40 und kabeleinlaufseitigem Ende 16 des Koaxialsteckers 10 ersetzt werden kann, beispielsweise durch einen Bajonettverschluß oder einen Schiebeverschluß. Mit Ausnahme des entsprechenden Abisolierens des Innenleiters 88 des Koaxialkabels 84, dem Einführen in das offene Ende 80 der Anpreßmutter 40 und dem Festschrauben der Anpreßmutter 40 sind keine weiteren Arbeitsgänge zum Kontaktieren erforderlich. Es ist lediglich bevorzugt in einer Seitenwand 99 des kabeleinlaufseitigen Außenleiters 18 des Koaxialsteckers 10 eine beispielsweise kreisförmige Sichtöffnung vorgesehen, durch die hindurch eine Bedienungsperson vor dem Festziehen der Anpreßmutter 40 feststellen kann, ob der Innenleiter 88 des eingeschobenen Koaxialkabels 84 in der vorbestimmten Position in der kreisförmigen Ausnehmung 38 angelangt ist oder nicht. Diese Öffnung wird nach dem Festziehen der Anpreßmutter 40 und der dadurch erfolgenden entsprechenden Kontaktierung von Außenleiter 86 und Innenleiter 88 des Koaxialkabels 84 in geeigneter Weise verschlossen, beispielsweise durch einen einschraubbaren Deckel.As can also be seen directly from FIGS. 2-6, contact is made of the outer conductor 86 and inner conductor 88 of the coaxial cable 84 automatically by simply screwing on the pressure nut 40. It is clear that the Screw connection also by a correspondingly different holding connection between Press nut 40 and end 16 of the coaxial connector 10 on the cable inlet side can be replaced, for example by a bayonet lock or a Sliding closure. With the exception of the corresponding stripping of the inner conductor 88 of the coaxial cable 84, the insertion into the open end 80 of the pressure nut 40 and the tightening of the pressure nut 40 are no further operations required to contact. It is only preferred in one side wall 99 of the cable inlet side outer conductor 18 of the coaxial connector 10 a For example, circular viewing opening is provided through which an operator before tightening the pressure nut 40 can determine whether the Inner conductor 88 of the inserted coaxial cable 84 in the predetermined position arrived in the circular recess 38 or not. This opening is after tightening the pressure nut 40 and the corresponding corresponding Contacting of outer conductor 86 and inner conductor 88 of the coaxial cable 84 closed in a suitable manner, for example by a screw-in Cover.
