Description

Die Erfindung bezieht sich auf einen elektrischen Steckverbinder gemaß dem Oberbegriff des Anspruchs 1.The invention relates to an electrical connector according to the preamble of claim 1.

Elektrische Steckverbinder werden in vielen Bereichen der Elektrotechnik, so z.B. in der Nachrichten-, Steuerungs-, Meß- und Regeltechnik sowie im Fahrzeugbau eingesetzt. Das Gehäuse solcher Steckverbinder ist häufig rund und wird in den unterschiedlichsten Größen hergestellt. Je nach Einsatzzweck weist der Steckverbinder eine unterschiedliche Anzahl an Kontakten in Stift- oder Buchsenform auf. In bestimmten Anwendungsgebieten, in denen es auf eine sichere und störungsfreie Übertragung von Daten oder Signalen ankommt, werden Kabel verwendet, die mit einer meist aus einem Metalldrahtgeflecht gebildeten Abschirmung umgeben sind. Damit die Abschirmung solcher Übertragungswege an den elektrischen Steckverbindungen keine Lücke aufweist, ist die Abschirmung des Kabels in solchen Fällen mit dem Gehäuse des Steckverbinders elektrisch leitend verbunden. Oftmals werden an die elektrische Steckverbindung zusätzlich noch besondere Anforderungen hinsichtlich der Feuchtigkeitsdichtheit gestellt, beispielsweise beim Einsatz in Fabrikhallen, in Fahrzeugen oder in Außenbereichen.Electrical connectors are used in many areas of electrical engineering, for example in communications, control, measurement and regulation technology and in vehicle construction. The housing of such connectors is often round and is manufactured in a wide variety of sizes. Depending on the application, the connector has a different number of contacts in the form of a pin or socket. In certain areas of application in which a secure and interference-free transmission of data or signals is important, cables are used which are surrounded by a shield, which is usually formed from a metal wire mesh. To ensure that the shielding of such transmission paths on the electrical plug connections does not have a gap, the shielding of the cable is connected in an electrically conductive manner to the housing of the plug connector in such cases. Often, the electrical plug connection is also subject to special requirements with regard to moisture tightness, for example when used in factory halls, in vehicles or outdoors.

Aus der DE-U-90 15 056 ist ein Steckverbinder bekannt, bei dem zur elektrischen Verbindung zwischen einer Kabelabschirmung und dem Steckverbindergehäuse sowie zur Abdichtung desselben separate Bauteile vorgesehen sind. Das zur Abdichtung eingesetzte Bauteil ist hülsenförmig und besteht aus elektrisch nichtleitendem Elastomermaterial. Im zusammengebauten Zustand drückt ein korbförmiges Klemmelement eine Innenkante des hülsenförmigen Dichtbauteils, dessen Innendurchmesser größer als der Außendurchmesser des Kabels einschließlich seiner Isolierung ist, gegen die Kabelisolierung.From DE-U-90 15 056 a connector is known in which separate components are provided for the electrical connection between a cable shield and the connector housing and for sealing the same. The component used for sealing is sleeve-shaped and consists of electrically non-conductive elastomer material. In the assembled state, a basket-shaped clamping element presses an inner edge of the sleeve-shaped sealing component, the inside diameter of which is larger than the outside diameter of the cable including its insulation, against the cable insulation.

Aus der DE-A-34 05 956 ist eine elektrische Steckverbindung mit einem Kombinationsbauteil bekannt, bei dem eine schraubenförmig gewundene Feder teilweise in einen Ring aus Elastomermaterial eingebettet ist. Im Einbauzustand ist das Kombinationsbauteil im Steckverbindergehäuse in radialer Richtung zusammengedrückt gehalten, wobei die gewundene Feder den elektrischen Kontakt zwischen einer auf ein Kabel und dessen Abschirmung geschobenen Hülse und dem zusammengekuppelten Steckverbindergehäuse herstellt, während der Ring aus Elastomermaterial die Kontaktflächen zwischen Hülse und Feder sowie zwischen Feder und Gehäuse abdichtet. Das Kombinationsbauteil muß relativ aufwendig beispielsweise durch Umspritzen der gewundenen Feder mit Elastomermaterial hergestellt werden und eignet sich nicht dazu, direkt auf eine Kabelabschirmung aufgesetzt zu werden.From DE-A-34 05 956 an electrical plug connection with a combination component is known, in which a helically wound spring is partially embedded in a ring made of elastomer material. In the installed state, the combination component in the connector housing is kept compressed in the radial direction, the coiled spring making electrical contact between a sleeve pushed onto a cable and its shield and the coupled connector housing, while the ring made of elastomer material makes the contact surfaces between the sleeve and the spring and between the spring and seals the housing. The combination component has to be produced in a relatively complex manner, for example by overmolding the coiled spring with elastomer material and is not suitable for being placed directly on a cable shield.

Aus der DE-A-24 05 241 ist ein Kontaktelement in Gestalt eines offenen Rings aus nichtleitendem Elastomermaterial bekannt, der mit einer leitenden Schicht beispielsweise aus einem Drahtgeflecht oder einer dünnen Metallfolie ummantelt ist. Das ringförmige Kontaktelement, das direkt auf einer Kabelabschirmung aufliegt und die elektrische Verbindung zwischen dieser und einem Steckverbindergehäuse herstellt, ist aufgrund der Ummantelung mit Drahtgeflecht oder Metallfolie nicht zur Abdichtung gegen Feuchtigkeit geeignet.From DE-A-24 05 241 a contact element in the form of an open ring made of non-conductive elastomer material is known, which is coated with a conductive layer, for example made of a wire mesh or a thin metal foil. The ring-shaped contact element, which rests directly on a cable shield and establishes the electrical connection between it and a connector housing, is not suitable for sealing against moisture due to the sheathing with wire mesh or metal foil.

Aus der GB-A-2 181 607 ist eine Kabeltülle aus elektrisch leitendem, elastischem Material bekannt, die bei der Zuführung abgeschirmter Kabel in elektronische Geräte zum Einsatz kommt und den elektrischen Kontakt zwischen der Kabelabschirmung und einem Gehäuse des elektronischen Geräts herstellt. Eine spezielle Abdichtung der Kabelzuführung gegen Feuchtigkeit wird mit dieser Kabeltülle nicht erzielt.From GB-A-2 181 607 a cable grommet made of electrically conductive, elastic material is known, which is used for feeding shielded cables into electronic devices comes and makes the electrical contact between the cable shield and a housing of the electronic device. A special sealing of the cable feed against moisture is not achieved with this cable grommet.

Aus der gattungsbildenden FR-A-2 514 577 ist ein elektrischer Steckverbinder bekannt, bei dem ein hülsenförmiges Elastomerteil aus elektrisch leitendem Material zur Herstellung eines guten Massekontakts zwischen einer Kabelabschirmung und dem Steckverbindergehäuse vorgesehen ist. Das hülsenförmige Elastomerteil sitzt an einem Kabelende direkt auf dem Abschirmgeflecht, das durch Entfernen eines Stücks der Kabelisoliergung freigelegt worden ist, und ist zwischen zwei ebenfalls hülsenförmigen Gehäuseteilen gehalten, die konzentrisch zueinander angeordnet und mittels einer Schraubverbindung verbunden sind. Beim Zusammenschrauben der beiden hülsenförmigen Gehäuseteile wird das hülsenförmige Elastomerteil im wesentlichen radial gegen das Abschirmgeflecht gedrückt und stellt damit eine gute elektrische Verbindung zwischen der Kabelabschirmung und dem Steckverbindergehäuse her. Zur Abdichtung gegen Feuchtigkeit ist eine separate, auf der Kabelisolierung angeordnete Dichtung sowie ferner eine zwischen den beiden hülsenförmigen Gehäuseteilen angeordneter O-Ring-Dichtung vorhanden.From the generic FR-A-2 514 577 an electrical connector is known, in which a sleeve-shaped elastomer part made of electrically conductive material is provided for producing good ground contact between a cable shield and the connector housing. The sleeve-shaped elastomer part sits at one end of the cable directly on the shielding braid, which has been exposed by removing a piece of the cable insulation, and is held between two likewise sleeve-shaped housing parts which are arranged concentrically to one another and are connected by means of a screw connection. When the two sleeve-shaped housing parts are screwed together, the sleeve-shaped elastomer part is pressed essentially radially against the shielding braid and thus establishes a good electrical connection between the cable shielding and the connector housing. For sealing against moisture there is a separate seal arranged on the cable insulation and also an O-ring seal arranged between the two sleeve-shaped housing parts.

Der Erfindung liegt die Aufgabe zugrunde, einen elektrischen Steckverbinder für abgeschirmte Kabel zu schaffen, der leicht und schnell montiert werden kann, auch bei nicht optimaler Montage einen einwandfreien Kontakt zwischen Abschirmung und Gehäuse gewährleistet, einfach geöffnet und danach wieder zusammengebaut werden kan und zudem gegen Feuchtigkeit abgedichtet und kostengünstig herstellbar sein soll.The invention has for its object to provide an electrical connector for shielded cable that can be easily and quickly installed, ensures perfect contact between the shield and the housing even when the installation is not optimal, can be easily opened and then reassembled and can also be protected against moisture sealed and should be inexpensive to manufacture.

Diese Aufgabe ist erfindungsgemäß mit einem Steckverbinder gelöst, der die Merkmale des Anspruchs 1 aufweist. Erfindungsgemäß übernimmt also das Elastomerteil, daß die Form einer über das Kabelende geschobenen Hülse oder Manschette hat, aufgrund seiner im Einbauzustand axialen Kompression sowohl die Abdichtung gegen Feuchtigkeit als auch die elektrisch leitende Verbindung zwischen Kabelabschirmung und Steckverbindergehäuse. Die elektrische Leitfähigkeit von normalerweise nicht leitfähigem elastisch nachgiebigem Material kann auf verschiedene Weise erreicht werden.This object is achieved with a connector having the features of claim 1. According to the invention, the elastomer part, which has the shape of a sleeve or sleeve pushed over the end of the cable, takes on both the sealing against moisture and the electrically conductive connection between the cable shield and the connector housing due to its axial compression in the installed state. The electrical conductivity of normally non-conductive, resilient material can be achieved in various ways.

Bei einer Ausführungsform des erfindungsgemäßen Steckverbinders ist das Elastomerteil mit elektrisch leitenden Adern, beispielsweise feinen Metalldrähten, durchsetzt. Bei einer anderen vorteilhaften Ausführungsform ist das Elastomermaterial selbst elektrisch leitend. Elastomere können beispielsweise elektrisch leitend gemacht werden, indem ihnen bei der Herstellung Metallpulver beigemischt wird. Die elektrische Leitfähigkeit kann aber auch durch eine dünne Metalloberflächenbeschichtung des elastisch nachgiebigen Materials erreicht werden.In one embodiment of the connector according to the invention, the elastomer part is interspersed with electrically conductive wires, for example fine metal wires. In another advantageous embodiment, the elastomer material itself is electrically conductive. For example, elastomers can be made electrically conductive by adding metal powder to them during manufacture. The electrical conductivity can also be achieved by a thin metal surface coating of the resilient material.

Bevorzugt ist das Elastomerteil koaxial zum Kabel und zum Gehäuse des Steckverbinders angeordnet.The elastomer part is preferably arranged coaxially with the cable and the housing of the connector.

Das Elastomerteil kann mit Ubermaß gefertigt und in das Steckverbindergehäuse eingepreßt sein. Besonders bevorzugt wird das Elastomerteil von einer Verschraubung im Gehäuse gehalten. Die Verschraubung drückt das Elastomerteil in axialer Richtung zusammen, wodurch eine gute Abdichtung gegen Feuchtigkeit und ein unter allen Umständen einwandfreier Kontakt zum Steckverbindergehäuse erreicht werden. Gleichzeitig läßt sich der zusammengebaute Steckverbinder problemlos wieder öffnen.The elastomer part can be made with oversize and pressed into the connector housing. The elastomer part is particularly preferably held by a screw connection in the housing. The screw connection compresses the elastomer part in the axial direction, which ensures a good seal against moisture and perfect contact with the connector housing under all circumstances. At the same time, the assembled connector can be easily opened again.

Gemäß einer Ausführungsform weist das Elastomerteil in Axialrichtung gesehen außen einen Absatz auf, so daß ein dem Gehäuse zugewandter Endabschnitt des Elastomerteils einen kleineren Außendurchurchmesser hat als ein gegenüberliegender, vom Gehäuse abgewandter Endabschnitt.According to one embodiment, the elastomer part has a shoulder on the outside in the axial direction, so that an end section of the elastomer part facing the housing has a smaller outside diameter than an opposite end section facing away from the housing.

Zweckmäßig erstreckt sich das Kabel durch das Elastomerteil hindurch, wobei ein die Kabelabschirmung bildendes Metallgeflecht über den Endabschnitt mit kleinerem Außendurchmesser zurückgeschlagen ist.The cable expediently extends through the elastomer part, a metal braid forming the cable shield being folded back over the end section with a smaller outer diameter.

Bei einer weiteren Ausführungsform ist das Elastomerteil in Axialrichtung gesehen zwischen zwei elektrisch leitenden Ringen angeordnet. Der vordere Ring dient als Anschlag und sorgt dafür, daß das umgeschlagene Metallgeflecht der Kabelabschirmung gleichmäßig gegen das Elastomerteil gepreßt wird, während der zwischen dem Elastomerteil und der Verschraubung angeordnete hintere Ring verhindert, daß beim Einschrauben der Verschraubung in das Gehäuse eine Drehbewegung auf das Elastomerteil übertragen wird.In a further embodiment, the elastomer part, viewed in the axial direction, is arranged between two electrically conductive rings. The front ring serves as a stop and ensures that the folded-up metal braid of the cable shield is pressed evenly against the elastomer part, while the rear ring arranged between the elastomer part and the screw connection prevents a rotational movement from being transmitted to the elastomer part when the screw connection is screwed into the housing becomes.

Bei einer anderen Ausführungsform ist die Außenseite des hülsenförmigen Elastomerteils konisch ausgebildet. Bevorzugt ist eine Buchse mit konisch ausgebildeter Innenseite um das Elastomerteil herum angeordnet. Bei dieser Ausführungsform ist es zweckmäßig, wenn das Elastomerteil in Axialrichtung aufgeschnitten ist. Das Elastomerteil kann dann ohne Schwierigkeiten um einen Teil der Kabelabschirmung gelegt werden, der bei dieser Ausführungsform über die Kabelisolierung zurückgeschlagen wird. Im Gegensatz zu den vorher beschriebenen Ausführungsformen ist die Kabelabschirmung hier also nicht über das Elastomerteil zurückgeschlagen, sondern das Elastomerteil umgibt den zurückgeschlagenen Teil der Abschirmung.In another embodiment, the outside of the sleeve-shaped elastomer part is conical. A bushing with a conical inside is preferably arranged around the elastomer part. In this embodiment, it is expedient if the elastomer part is cut open in the axial direction. The elastomer part can then be placed without difficulty around a part of the cable shield, which in this embodiment is knocked back over the cable insulation. In contrast to the previously described embodiments, the cable shield is here not folded back over the elastomer part, but rather the elastomer part surrounds the part of the shield that has been pushed back.

Ein elektrischer Steckverbinder 10 hat ein im wesentlichen kreiszylindrisches Gehäuse 12 mit einem axial durchgehenden Innenraum 14. In Fig. 1 von rechts kommend sind mehrere Adern 32 eines elektrischen Kabels 30 in den Innenraum 14 geführt. Die Adern 32 erstecken sich durch den Innenraum 14 zu einem in einer Metallfassung sitzenden Kontaktträger (nicht gezeigt), wobei die einzelnen Adern 32 mit im Kontaktträger angeordneten Kontakten beispielsweise durch Löten oder Crimpen elektrisch leitend verbunden sind. Die nicht gezeigte Metallfassung ist über ein im vorderen, in Fig. 1 linken Teil des ebenfalls aus Metall bestehenden Gehäuses 12 ausgebildetes Gewinde 16 mit dem Gehäuse verschraubt. In einer sich in axialer Richtung an das Gewinde 16 anschließenden, ebenfalls im Innenraum 14 des Gehäuses 12 ausgebildeten Rechtecknut ist eine Elastomerdichtung 18 angeordnet, die die Verbindung zwischen Metall fassung und Gehäuse 12 abdichtet.An electrical connector 10 has an essentially circular cylindrical housing 12 with an axially continuous interior 14. In FIG. 1, coming from the right, a plurality of wires 32 of an electrical cable 30 are led into the interior 14. The cores 32 extend through the interior 14 to form a contact carrier (not shown) seated in a metal socket, the individual cores 32 having contacts arranged in the contact carrier, for example by soldering or crimping are electrically connected. The metal frame (not shown) is screwed to the housing via a thread 16 formed in the front part, which is also made of metal, on the left in FIG. 1. In an axially adjoining the thread 16, also in the interior 14 of the housing 12 formed rectangular groove, an elastomer seal 18 is arranged which seals the connection between the metal frame and the housing 12.

Auf die Metall fassung ist eine diese konzentrisch umgebende Rändelmutter 20 aufgesteckt. Die Rändelmutter 20 ist in üblicher Weise durch einen auf der Metall fassung ausgebildeten Kragen drehbar auf dieser gehalten und weist ein Innengewinde zur Verschraubung mit einem nicht gezeigten komplementären Gegenstecker auf.A knurled nut 20 concentrically surrounding this is plugged onto the metal frame. The knurled nut 20 is rotatably held in the usual manner by a collar formed on the metal socket and has an internal thread for screwing with a complementary mating connector, not shown.

Über eine äußere Isolierung 31 des zum Steckverbinder 10 weisenden Ende des Kabels 30 ist ein hülsenförmiges Elastomerteil 22 aus elektrisch leitendem Material geschoben. Etwa in der Mitte seiner in Axialrichtung gesehenen Längserstreckung weist die Außenseite des Elastomerteils 22 einen Absatz auf, so daß ein dem Steckverbinder 10 zugewandter, vorderer Endabschnitt 24 des Elastomerteils 22 einen geringeren Durchmesser aufweist als ein gegenüberliegender, hinterer Endabschnitt 23. Über diesen Endabschnitt 24 ist die aus einem Metallgeflecht bestehende Abschirmung 34 des Kabels 30 zurückgeschlagen. Auf das Kabel 30 aufgeschoben sind weiterhin zwei Metallringe 25 und 26, auf deren Funktion noch eingegangen werden wird, sowie eine Schraube 27 mit Panzergewinde 27a. Das Gewinde 27a paßt in ein entsprechendes Gewinde 28, das als Innengewinde im hinteren Teil des Gehäuses 12 ausgebildet ist.A sleeve-shaped elastomer part 22 made of electrically conductive material is pushed over an outer insulation 31 of the end of the cable 30 facing the plug connector 10. Approximately in the middle of its longitudinal extension, as seen in the axial direction, the outside of the elastomer part 22 has a shoulder, so that a front end section 24 of the elastomer part 22 facing the plug connector 10 has a smaller diameter than an opposite, rear end section 23 the shield 34 of the cable 30 consisting of a metal braid is knocked back. Two metal rings 25 and 26, the function of which will be discussed in more detail, and a screw 27 with armored thread 27a are also pushed onto the cable 30. The thread 27a fits into a corresponding thread 28 which is designed as an internal thread in the rear part of the housing 12.

Der Steckverbinder 10 wird wie folgt zusammengebaut: Zunächst wird das Kabel 30 in herkömmlicher Weise für den Anschluß am Steckverbinder 10 vorbereitet, d.h. die Isolierung 31 des Kabels wird vom Kabelende her ein Stück weit entfernt, ohne dabei die Abschirmung 34 zu verletzen. Sodann werden nacheinander die Schraube 27, der Metallring 26 sowie das Elastomerteil 22 über das Kabelende geschoben. Der Innendurchmesser des hülsenförmigen Elastomerteils 22 ist dabei etwas kleiner als der Außendurchmesser des Kabels 30 mit Isolierung, so daß das Elastomerteil 22 streng auf dem Kabel 30 sitzt. Wie aus Fig. 1 ersichtlich, wird das Elastomerteil 22 so weit auf das Kabel 30 aufgeschoben, bis die dem Gehäuse 12 zugewandte Stirnseite des Elastomerteils 22 in etwa mit dem Ende der äußeren Kabelisolierung 31 abschließt. Als nächstes wird der über das Ende der Kabelisolierung hinausstehende Teil der Abschirmung 34 über den Endabschnitt 24 des Elastomerteils 22 zurückgeschlagen. Nach Aufschieben des Metallrings 25 wird das so vorbereitete Kabelende mit der Hand in das Gehäuse 12 des Steckverbinders 10 hineingedrückt. Dies ist leicht möglich, da der Außendurchmesser des hinteren Endabschnitts 23 des Elastomerteils 22 etwas kleiner ist als der Innendurchmesser des Gewindes 28. Zuletzt wird die Schraube 27 im Innengewinde 28 des Gehäuses 12 fest verschraubt. Hierzu sind auf der Außenseite des Gehäuses 12 Flächen 13 vorgesehen, die es gestatten, einen Schraubenschlüssel oder eine Zange anzusetzen. Die Verbindung der Adern 32 mit den nicht gezeigten Kontakten erfolgt auf herkömmliche Weise und braucht daher nicht näher erläutert zu werden.The connector 10 is assembled as follows: First, the cable 30 is prepared in a conventional manner for connection to the connector 10, ie the insulation 31 of the cable is removed a little from the end of the cable, without damaging the shield 34. Then the screw 27, the metal ring 26 and the elastomer part 22 are pushed one after the other over the cable end. The inside diameter of the sleeve-shaped elastomer part 22 is somewhat smaller than the outside diameter of the cable 30 with insulation, so that the elastomer part 22 sits tightly on the cable 30. As can be seen from FIG. 1, the elastomer part 22 is pushed onto the cable 30 until the end face of the elastomer part 22 facing the housing 12 approximately ends with the end of the outer cable insulation 31. Next, the portion of the shield 34 projecting beyond the end of the cable insulation is flipped back over the end portion 24 of the elastomeric member 22. After the metal ring 25 has been pushed on, the cable end thus prepared is pressed by hand into the housing 12 of the connector 10. This is easily possible since the outer diameter of the rear end section 23 of the elastomer part 22 is somewhat smaller than the inner diameter of the thread 28. Finally, the screw 27 is screwed tightly into the internal thread 28 of the housing 12. For this purpose, surfaces 13 are provided on the outside of the housing 12, which allow a wrench or pliers to be attached. The connection of the wires 32 to the contacts, not shown, takes place in a conventional manner and therefore need not be explained in more detail.

Aus Fig. 2 ist zu ersehen, daß das Elastomerteil 22 von der Schraube 27 in axialer Richtung zusammengedrückt ist, wobei sich sein Durchmesser vergrößert hat, so daß die Mantelfläche des Endabschnitts 23 sich in sattem Kontakt mit dem Innengewinde 28 befindet. Der Metallring 25 dient als Anschlag für das Elastomerteil 22 und sorgt zur weiteren Verbesserung des Kontakts zwischen Gehäuse 12 und Abschirmung 34 dafür, daß diese fest an das Elastomerteil 22 gepreßt wird. Um beim Einschrauben der Schraube 27 möglichst kein Drehmoment auf das Elastomerteil 22 zu übertragen und dessen Mitdrehen zu verhindern, ist der Metallring 26 zwischen der Schraube 27 und dem Elastomerteil 22 angeordnet.From Fig. 2 it can be seen that the elastomer part 22 is compressed by the screw 27 in the axial direction, its diameter has increased so that the outer surface of the end portion 23 is in close contact with the internal thread 28. The metal ring 25 serves as a stop for the elastomer part 22 and, to further improve the contact between the housing 12 and the shield 34, ensures that it is pressed firmly against the elastomer part 22. To screw in To prevent the screw 27 from transmitting any torque to the elastomer part 22 and to prevent it from rotating, the metal ring 26 is arranged between the screw 27 and the elastomer part 22.

Selbst bei nicht ganz fachgerechter Vorbereitung des Kabelendes, wenn beispielsweise die Abschirmung 34 nicht über den gesamten Endabschnitt 24 des Elastomerteils 22 zurückgeschlagen ist oder nur an der Stirnseite des Endabschnitts 24 zusammengeschoben ist, wird wegen des innigen Kontakts des Elastomerteils 22 aus elektrisch leitendem Material mit dem Gehäuse 12 eine einwandfreie, elektrisch leitende Verbindung zwischen der Abschirmung 34 und dem Gehäuse hergestellt, wobei das Elastomerteil 22 aufgrund des Materials und der axialen Kompression im Gehäuse die Steckverbindung gleichzeitig gut gegen Feuchtigkeit abdichtet.Even if the cable end is not completely properly prepared, for example if the shield 34 is not folded back over the entire end section 24 of the elastomer part 22 or is only pushed together on the end face of the end section 24, the elastomer part 22 is made of electrically conductive material with the due to the intimate contact Housing 12 made a perfect, electrically conductive connection between the shield 34 and the housing, the elastomeric part 22 at the same time seals the connector well against moisture due to the material and the axial compression in the housing.

In Fig. 3 ist eine andere Ausführungsform des elektrischen Steckverbinders 10 gezeigt. Sie unterscheidet sich von dem in den Figuren 1 und 2 gezeigten Ausführungsbeispiel vor allem durch die andere Form des Elastomerteils 22. Im Gegensatz zur ersten Ausführungsform weist die Außenseite des hülsenförmigen Elastomerteils 22 keine Stufe auf, sondern ist stattdessen konisch ausgebildet. Dabei ist die Seite des Elastomerteils 22 mit dem größeren Außendurchmesser dem Gehäuse 12 des Steckverbinders zugewandt. Statt des hinteren Metallrings 26 des ersten Ausführungsbeispiels ist bei dem zweiten Ausführungsbeispiel eine Buchse 21 vorhanden, deren Innenseite ebenfalls konisch ausgebildet ist. Die Innenseite der Buchse 21 ist so bemessen, daß die Buchse auf das Elastomerteil 22 aufgeschoben werden kann. Auf der in Fig. 3 rechten Seite weist die Buchse 21 einen nicht gezeigten, radial nach innen ragenden und als Anschlag dienenden umlaufenden Rand auf, der verhindert, daß die Buchse 21 gewaltsam zu weit auf das Elastomerteil 22 aufgeschoben wird. Die Schraube 27 weist bei diesem Ausführungsbeispiel im Bereich ihres Gewindes 27a eine konzentrisch zu diesem angeordnete, zylindrische innere Ausnehmung auf, deren Durchmesser größer als der Außendurchmesser der Buchse 21 ist.Another embodiment of the electrical connector 10 is shown in FIG. 3. It differs from the exemplary embodiment shown in FIGS. 1 and 2 primarily by the different shape of the elastomer part 22. In contrast to the first embodiment, the outside of the sleeve-shaped elastomer part 22 has no step, but is instead conical. The side of the elastomer part 22 with the larger outside diameter faces the housing 12 of the connector. Instead of the rear metal ring 26 of the first embodiment, a bushing 21 is provided in the second embodiment, the inside of which is also conical. The inside of the bushing 21 is dimensioned such that the bushing can be pushed onto the elastomer part 22. On the right-hand side in FIG. 3, the bushing 21 has a not shown, radially inwardly projecting and serving as a stop peripheral edge, which prevents the bushing 21 from being pushed too far onto the elastomer part 22 by force. The screw 27 has In this exemplary embodiment, in the area of its thread 27a, there is a cylindrical inner recess arranged concentrically to the latter, the diameter of which is larger than the outer diameter of the bushing 21.

Wie aus Fig. 4 ersichtlich, ist im zusammengebauten Zustand die Buchse 21 konzentrisch um das Elastomerteil 22 herum angeordnet und überträgt die über die Schraube 27 eingeleitete und in Axialrichtung wirkende Kraft auf das Elastomerteil 22, so daß dieses in Axialrichtung komprimiert wird.As can be seen from FIG. 4, in the assembled state, the bushing 21 is arranged concentrically around the elastomer part 22 and transmits the force introduced via the screw 27 and acting in the axial direction to the elastomer part 22, so that it is compressed in the axial direction.

Beim Zusammenbauen des Steckverbinders ist gegenüber der ersten Ausführungsform zu beachten, daß die Abschirmung 34 nicht über das Elastomerteil 22, sondern über die Kabelisolierung 31 zurückgeschlagen wird. Sodann wird das Elastomerteil 22, das gemäß Fig. 5 in Axialrichtung aufgeschnitten ist, über die zurückgeschlagene Abschirmung 34 gelegt und daraufhin die Buchse 21 von Hand ein Stück auf das Elastomerteil 22 aufgeschoben. Das so vorbereitete Kabelende wird dann in das Gehäuse 12 des Steckverbinders 10 hineingedrückt. Anschließend wird die Schraube 27 im Innengewinde 28 des Gehäuses 12 fest verschraubt. Dabei wirkt die in Fig. 4 zu erkennende innere Ausnehmung der Schraube 27 bezüglich der Buchse 21 zentrierend, so daß die Buchse 21 gleichmäßig auf das Elastomerteil 22 gedrückt wird und dieses in axialer und radialer Richtung zusammenpreßt. Analog zum Metallring 26 des ersten Ausführungsbeispiels verhindert die Buchse 21, daß sich das Elastomerteil 22 beim Einschrauben der Schraube 27 mitdreht.When assembling the connector, it should be noted in comparison with the first embodiment that the shield 34 is not pushed back over the elastomer part 22, but over the cable insulation 31. The elastomer part 22, which is cut open in the axial direction according to FIG. 5, is then placed over the folded-back shield 34 and the bush 21 is then pushed onto the elastomer part 22 by hand. The cable end thus prepared is then pressed into the housing 12 of the connector 10. The screw 27 is then firmly screwed into the internal thread 28 of the housing 12. The inner recess of the screw 27 shown in FIG. 4 has a centering effect with respect to the bushing 21, so that the bushing 21 is pressed evenly onto the elastomer part 22 and compresses it in the axial and radial directions. Analogous to the metal ring 26 of the first exemplary embodiment, the bushing 21 prevents the elastomer part 22 from rotating when the screw 27 is screwed in.

Im zusammengebauten Zustand (sh. Fig. 4) ist das Elastomerteil 22 fest gegen den vorderen Metallring 25 und die Innenseite des Gehäuses 10 sowie gegen die Abschirmung 34 bzw. die Kabelisolierung 31 gepreßt, so daß eine einwandfrei elektrisch leitende und zugleich feuchtigkeitsdichte Verbindung zwischen der Abschirmung und dem Steckverbindergehäuse geschaffen ist. Daneben wirkt die Kombination des konischen Elastomerteils 22 mit der Buchse 21 bezüglich des Kabels 30 zugentlastend.In the assembled state (see Fig. 4), the elastomer part 22 is pressed firmly against the front metal ring 25 and the inside of the housing 10 and against the shield 34 or the cable insulation 31, so that a perfectly electrically conductive and at the same time moisture-proof connection between the Shield and the connector housing created is. In addition, the combination of the conical elastomer part 22 with the bushing 21 has a strain-relieving effect on the cable 30.

Der in Fig. 5 angedeutete, sich durch das Aufschneiden des Elastomerteils 22 in Axialrichtung ergebende Schlitz 22a kann auch eine andere als die in Fig. 5 dargestellte Form aufweisen. Statt der im Querschnitt stufenförmigen Schlitzform gemäß Fig. 5 können auch eine oder mehrere Nuten vorgesehen sein, in die komplementäre Vorsprünge eingreifen. In jedem Fall schließt sich aufgrund der Komprimierung des Elastomerteils 22 auch in radialer Richtung, die durch die konisch ausgeführte Innenseite der Buchse 21 bewirkt wird, beim Einschrauben der Schraube 27 in das Gewinde 28 der Schlitz 22a bis zur vollständigen Dichtheit.The slot 22a indicated in FIG. 5 and resulting from the cutting of the elastomer part 22 in the axial direction can also have a shape other than that shown in FIG. 5. 5, one or more grooves can also be provided, in which complementary projections engage. In any case, due to the compression of the elastomer part 22 also in the radial direction, which is brought about by the conical inside of the bushing 21, when the screw 27 is screwed into the thread 28, the slot 22a closes to complete tightness.
