Die Erfindung betrifft einen elektrischen Steckverbinder mit Schnellverriegelung, mit einem ersten Verbinderelement und einem zweiten Verbinderelement, die mit einem Kupplungsorgan miteinander verbunden sind und die einen Innenleiter sowie einen Aussenleiter bilden, wobei ein Aussenleiterteil des zweiten Verbinderteils stirnseitig einen elektrischen Kontakt bildet, und wobei zwischen dem ersten Verbinderelement und dem zweiten Verbinderelement ein federelastisches Kontaktelement angeordnet ist.The invention relates to an electrical connector Quick lock, with a first connector element and a second connector element with each other with a coupling member are connected and which have an inner conductor and an outer conductor form, with an outer conductor part of the second connector part forms an electrical contact at the end, and wherein between the first connector element and the second connector element a resilient contact element is arranged.

Ein Steckverbinder der genannten Art ist im Stand der Technik aus der WO 00/05785 bekannt geworden. Bei diesem weist das Kupplungsorgan einen Verriegelungsring auf, der die beiden Verbinderelemente lösbar miteinander verbindet. Zum Lösen der Verbindung wird eine Entriegelungshülse achsial verschoben. Dadurch wird der Verriegelungsring aus einer Aussennut des zweiten Verbinderelementes herausgehoben. Beim Zusammenstecken der beiden Verbinderelemente rastet der Verriegelungsring selbsttätig in die genannte Aussennut des zweiten Verbinderelementes ein und verriegelt dieses mit dem anderen Verbinderelement. Zur Toleranzkompensation des Kupplungsorganes ist eine Hülse mit Federzungen vorgesehen, die an ihrem einen Ende fest mit dem ersten Verbinderelement verbunden ist und die an ihrem anderen Ende innenseitig mit den Federzungen am zweiten Verbinderelement verrastet ist. Bei diesem Steckverbinder ist insbesondere nachteilig, dass der konstruktive Aufbau vergleichsweise aufwendig ist. Insbesondere ist die genannte Hülse bezüglich ihrer Herstellung und ihrer Montage vergleichsweise aufwendig. A connector of the type mentioned is in the prior art become known from WO 00/05785. In this, the coupling member a locking ring on the two connector elements releasably connects. To release the connection an unlocking sleeve is moved axially. Thereby the locking ring is made from an external groove of the second connector element lifted. When putting the two together The locking ring automatically snaps into the connector elements said outer groove of the second connector element and locks this with the other connector element. For tolerance compensation the coupling member is a sleeve with spring tongues provided that fixed at one end to the first Connector element is connected and the inside at its other end locked with the spring tongues on the second connector element is. This connector is particularly disadvantageous that the construction is comparatively complex. In particular is the sleeve mentioned in terms of their manufacture and their assembly is comparatively complex.

Der Erfindung liegt die Aufgabe zugrunde, einen elektrischen Steckverbinder der genannten Art zu schaffen, der mechanisch einfacher hergestellt werden kann und der dennoch gute HF-Eigenschaften besitzt.The invention has for its object an electrical To create connectors of the type mentioned, the mechanical can be manufactured more easily and still has good RF properties has.

Die Aufgabe ist bei einem elektrischen Steckverbinder der genannten Art dadurch gelöst, dass das Kontaktelement eine Ringscheibe ist, die unter achsialer Spannung zwischen den beiden Aussenleiterteilen an diesen anliegt und umlaufende geschlossene Kontaktflächen bildet. Versuche haben gezeigt, dass der erfindungsgemässe Steckverbinder sehr gute HF-Eigenschaften und insbesondere eine gute passive Intermodulation und geringe HF-Abstrahlung besitzt. Die Herstellungskosten sind bei sehr guten HF-Eigenschaften dann besonders niedrig, wenn gemäss einer Weiterbildung der Erfindung das Kontaktelement tellerfederartig ausgebildet ist. Ein solches Kontaktelement kann sehr kostengünstig hergestellt werden. Die genannten HF-Eigenschaften sind dann besonders gut, wenn gemäss einer Weiterbildung der Erfindung das Kontaktelement die genannte Stirnseite entlang einer umlaufenden geschlossenen Kreislinie kontaktiert. Vorzugsweise kontaktiert das Kontaktelement beide Verbinderelemente entlang einer geschlossenen umlaufenden Kreislinie. Dies ergibt einen genau definierten Kontakt mit guter passiver Intermodulation und HF-Abstrahlung. Ein wesentlicher Vorteil der Erfindung besteht auch darin, dass achsiale Winkelabweichungen zwischen den beiden Verbinderelementen bis etwa 1° den HF-Kontakt nicht beeinträchtigen. Der Kontakt zeichnet sich somit durch eine hohe Biegestabliltät aus.The task is for an electrical connector of the named Art solved in that the contact element a Ring washer is under axial tension between the two Outer conductor parts abut against these and all-round closed Forms contact surfaces. Trials have shown that the connector according to the invention has very good RF properties and especially good passive intermodulation and low Has RF radiation. The manufacturing costs are very good HF properties are particularly low if according to one Development of the invention, the contact element like a plate spring is trained. Such a contact element can be very inexpensive getting produced. The HF properties mentioned are especially good if according to a further development of the invention the contact element said front side along a circumferential closed circular line contacted. Preferably the contact element contacts both connector elements a closed circumferential circular line. This results in one well-defined contact with good passive intermodulation and RF radiation. A major advantage of the invention is also in that axial angular deviations between the two Connector elements up to about 1 ° do not impair the HF contact. The contact is characterized by a high bending stability out.

Nach einer Weiterbildung der Erfindung weist das Kontaktelement einen inneren Bund auf und ist so ausgebildet, dass stets eine achsiale Restkraft bzw. Restspannung besteht. Damit ist sichergestellt, dass unabhängig von den Toleranzabweichungen des Kupplungsorganes eine achsiale Spannung aufrecht erhalten wird. Das Kontaktelement ist somit so aufgebaut, dass es nicht umstülpen kann, wie dies bei Tellerfedern üblicherweise möglich ist.According to a development of the invention, the contact element an inner collar and is designed so that always one axial residual force or residual stress exists. This ensures that regardless of the tolerance deviations of the coupling member axial tension is maintained. The The contact element is thus constructed so that it does not turn inside out can, as is usually possible with disc springs.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass das Kontaktelement auf der Aussenseite eines Isolators gelagert ist. Dieser Isolator ist vorzugsweise im ersten Verbinderelement angeordnet und zwischen dem Innenleiterteil und dem Aussenleiterteil angeordnet. Bei der Montage kann das Kontaktelement in einfacher Weise auf diesen Aussenleiter aufgeschoben werden. Der genannte Bund bzw. die Beurteilung an der Innenkante des Kontaktelementes erleichtert diese Montage wesentlich. Vorzugsweise ist das Kontaktelement in eine Aussennut des Isolators eingesetzt.According to a development of the invention, it is provided that Contact element is mounted on the outside of an insulator. This insulator is preferably arranged in the first connector element and between the inner conductor part and the outer conductor part arranged. When assembling the contact element in simpler Be pushed onto this outer conductor. The called collar or the assessment on the inner edge of the contact element this assembly is much easier. Preferably the contact element is inserted into an external groove of the insulator.

Besonders gute HF-Eigenschaften ergeben sich dann, wenn gemäss einer Weiterbildung der Erfindung die Stirnfläche des Aussenleiterteils des zweiten Verbinderelementes zu einer umlaufenden linienförmigen Kontaktfläche geschärft ist. Der Kontaktbereich zwischen dem Kontaktelement und dem zweiten Verbinderelement ist dann immer gleich und genau definiert.Particularly good HF properties result when according to a development of the invention, the end face of the outer conductor part of the second connector element to form a circumferential line Contact surface is sharpened. The contact area between the contact element and the second connector element then always the same and precisely defined.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features result from the dependent ones Claims, the following description and the Drawing.

Die Figur 1 zeigt einen elektrischen Steckverbinder 1, der ein erstes Verbinderelement 2 sowie ein zweites Verbinderelement 3 aufweist, die einen Aussenleiter 9 sowie einen Innenleiter 10 bilden. Die beiden Verbinderelemente 2 und 3 sind mit einem Kupplungsorgan 26 lösbar miteinander verbunden. Das Kupplungsorgan 26 weist in an sich bekannter Weise einen Verriegelungsring 5 auf, der in eine Aussennut 6 des zweiten Verbinderelementes 3 eingreift und an einer Schulter 29 des ersten Verbinderelementes 2 und an einem Halterand 7 ansteht. Um die Verriegelung zu lösen, wird eine Verriegelungshülse 4 in Richtung des Pfeiles 28 und somit in Figur 1 von rechts nach links verschoben. Mit einem umlaufenden inneren Rand 30 wird der Verriegelungsring 5 aus der Aussennut 6 herausgehoben und damit die Verriegelung gelöst. Beim Zusammenstecken der beiden Verbinderelemente 2 und 3 rastet der Verriegelungsring 5 selbsttätig in die Nut 6 ein.Figure 1 shows an electrical connector 1, the one first connector element 2 and a second connector element 3 has an outer conductor 9 and an inner conductor 10 form. The two connector elements 2 and 3 are with one Coupling member 26 releasably connected together. The coupling element 26 has a locking ring in a manner known per se 5 on, in an outer groove 6 of the second connector element 3 engages and on a shoulder 29 of the first connector element 2 and is at a holding edge 7. To the lock to solve, a locking sleeve 4 in the direction of Arrow 28 and thus shifted from right to left in Figure 1. With a peripheral inner edge 30, the locking ring 5 lifted out of the outer groove 6 and thus the lock solved. When plugging the two connector elements together 2 and 3 the locking ring 5 engages automatically in the Groove 6.

Um die Toleranz des Kupplungsorgans 26 zu kompensieren und um gute HF-Eigenschaften zu erreichen, ist ein Kontaktelement 16 vorgesehen, das zwischen einem Aussenleiterteil 11 des ersten Verbinderelementes 2 und einem Aussenleiterteil 12 des zweiten Verbinderelementes 3 angeordnet ist. Das Kontaktelement 16 bildet eine Tellerfeder und weist eine kegelförmige Ringscheibe 23 auf, die an ihrem Rand einen Bund 22 aufweist, der sich achsial erstreckt und deren Wandstärke um ein Mehrfaches kleiner ist als die Breite der Ringscheibe 23. Das Kontaktelement 16 besteht aus einem federelastischen Metall, beispielsweise einer geeigneten Kupferlegierung.To compensate for the tolerance of the coupling member 26 and around To achieve good HF properties is a contact element 16 provided that between an outer conductor part 11 of the first Connector element 2 and an outer conductor part 12 of the second Connector element 3 is arranged. The contact element 16 forms a plate spring and has a conical annular disk 23 on, which has at its edge a collar 22 which is axial extends and the wall thickness is several times smaller than the width of the annular disc 23. The contact element 16 consists of a resilient metal, for example a suitable one Copper alloy.

Wie insbesondere die Figur 3 deutlich zeigt, ist das Kontaktelement 16 zwischen einer Stirnseite 21 des Aussenleiterteils 12 und einer Kontaktfläche 20 des Aussenleiterteils 11 angeordnet. Zum Aussenleiterteil 12 bildet das Kontaktelement 16 eine umlaufende linienförmige sowie geschlossene Kontaktfläche A. Zum Aussenleiterteil 11 bildet das Kontaktelement 16 ebenfalls eine geschlossene umlaufende sowie kreisförmige Kontaktfläche B. Diese beiden Flächen A und B sind gemäss Figur 3 radial zueinander im Abstand angeordnet. Das vordere Ende 12a des Aussenleiterteils 12 ist an der Stirnseite 21 wie ersichtlich geschärft, sodass die Stirnfläche 21 lediglich im Bereich der geschlossenen Kreisfläche A am Kontaktelement 16 anliegt. Das Kontaktelement 16 kann in einem Grenzfall flächig an die Fläche 20 angelegt sein. Auch in diesem Grenzfall bleibt eine Restkraft und somit übt das Kontaktelement 16 auch in diesem Fall eine achsiale Spannung auf die beiden Aussenleiterteile 11 und 12 aus. Durch die achsiale Spannung des Kontaktelementes 16 wird wie erwähnt die Toleranz des Kupplungsorganes 26 kompensiert.As is particularly evident in FIG. 3, the contact element 16 between an end face 21 of the outer conductor part 12 and a contact surface 20 of the outer conductor part 11. For the outer conductor part 12, the contact element 16 forms a circumferential one linear and closed contact surface A. Zum Outer conductor part 11 also forms a contact element 16 closed peripheral and circular contact area B. This According to FIG. 3, both surfaces A and B are radial to one another spaced apart. The front end 12a of the outer conductor part 12 is sharpened on the end face 21 as can be seen, so that the end face 21 only in the area of the closed Circular area A bears on contact element 16. The contact element 16 can be applied to the surface 20 in a borderline case his. Even in this limit case, there remains a residual force and thus In this case too, the contact element 16 exercises an axial one Voltage on the two outer conductor parts 11 and 12. By the axial tension of the contact element 16 is, as mentioned the tolerance of the coupling member 26 compensated.

Das Kontaktelement 16 ist auf einem Isolator 15 gelagert, der in an sich bekannter Weise einen Innenleiterteil 13 aufnimmt, der gemäss Figur 1 mit einem als Federbuchse ausgebildeten Innenleiterteil 14 verbunden ist. Wie insbesondere Figur 3 zeigt, ist in die Aussenseite des Isolators 15 eine umlaufende Nut 19 eingearbeitet, in welche das Kontaktelement 16 eingesetzt ist. Das Kontaktelement 16 ist somit auf dem Isolator 15 gelagert, was jedoch nicht zwingend ist. Zur Montage des Kontaktelementes 16 wird dieses auf den Isolator 15 aufgeschoben, was durch den Bund 22 wesentlich erleichtert wird. Das Aufsetzen des Kontaktelementes 16 kann auch automatisiert erfolgen. The contact element 16 is mounted on an insulator 15, which in in a known manner receives an inner conductor part 13 which 1 with an inner conductor part designed as a spring bushing 14 is connected. As particularly shown in FIG. 3, in the outside of the insulator 15 has a circumferential groove 19, in which the contact element 16 is inserted. The contact element 16 is thus mounted on the insulator 15, but what is not mandatory. For mounting the contact element 16 this is pushed onto the insulator 15, which is caused by the federal government 22 is made considerably easier. Attaching the contact element 16 can also be automated.

Die beiden Verbinderelemente 2 und 3 sind mit einem Dichtungsring 17 gegen einander abgedichtet, der in eine Innennut 18 des Aussenleiterteils 11 eingesetzt ist. Dieser Dichtungsring 17 liegt wie ersichtlich an der Aussenseite des Aussenleiterteils 12 an. Die Figur 2 zeigt das erste Verbinderelement 2 mit dem Kontaktelement 16 in der entspannten Ruhestellung. Wird nun das zweite Verbinderelement 3 in das erste Verbinderelement 2 eingesteckt, so wird durch die Schulter 7 der Verriegelungsring 5 gespreizt und dieser rastet schliesslich in die Nut 6 ein. Gleichzeitig wird der Dichtungsring 17 komprimiert und das Kontaktelement 6 wird von der in Figur 3 gezeigten strichpunktierten Form in die mit ausgezogenen Linien gezeigte Form elastisch deformiert. Dadurch wird das Kontaktelement 16 gespannt und übt eine achsiale Kraft auf, welche den Verriegelungsring 5 an die Schulter 7 sowie an den Halterand 8 anpresst. Wird die Verbindung gelöst, so geht das Kontaktelement 16 wieder in die in Figur 2 gezeigte Ruhestellung zurück.The two connector elements 2 and 3 are with a sealing ring 17 sealed against each other, which in an inner groove 18 of Outer conductor part 11 is used. This sealing ring 17th is, as can be seen, on the outside of the outer conductor part 12 on. Figure 2 shows the first connector element 2 with the Contact element 16 in the relaxed rest position. Now will that second connector element 3 inserted into the first connector element 2, so the locking ring 5 is spread through the shoulder 7 and this finally snaps into the groove 6. simultaneously the sealing ring 17 is compressed and the contact element 6 is of the dash-dotted shape shown in Figure 3 elastically deformed into the shape shown with solid lines. As a result, the contact element 16 is tensioned and exercises one axial force on which the locking ring 5 to the shoulder 7 and pressed against the holding edge 8. If the connection is released, so the contact element 16 goes back to that shown in Figure 2 Rest position back.
