The two connectors are connected together to form inner (10) and outer (9) conductors, with an outer conductor part of the latter connector and a resilient contact between the two parts. A contact unit (16) with an annular disc (23) contacts two outer conductor parts (11,12) along a closed circular line.

Description

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 with quick lock, comprising a first connector element and a second connector element, which are interconnected with a coupling member and which form an inner conductor and an outer conductor, wherein an outer conductor part of the second connector part forms an electrical contact end face, 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 has become known in the art from WO 00/05785. In this, the coupling member has a locking ring which removably connects the two connector elements together. To release the connection, an unlocking sleeve is moved axially. As a result, the locking ring is lifted out of an outer groove of the second connector element. When mating the two connector elements of the locking ring automatically engages in said outer groove of the second connector element and locks it with the other connector element. For tolerance compensation of the coupling member, a sleeve is provided with spring tongues which is fixedly connected at its one end to the first connector element and which is locked at its other end on the inside with the spring tongues on the second connector element. In this connector is particularly disadvantageous that the structural design is relatively expensive. In particular, said sleeve is relatively expensive in terms of their manufacture and their installation.

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 to provide an electrical connector of the type mentioned, which can be made mechanically simpler and yet has good RF properties.

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 object is achieved in an electrical connector of the type mentioned in that the contact element is an annular disc which rests under axial tension between the two outer conductor parts of these and forms circumferential closed contact surfaces. Tests have shown that the connector according to the invention has very good HF properties and, in particular, good passive intermodulation and low RF radiation. With very good HF properties, the production costs are particularly low if, according to a development of the invention, the contact element is designed in the manner of a plate spring. Such a contact element can be produced very inexpensively. The above-mentioned HF properties are particularly good when, according to a development of the invention, the contact element makes contact with said end face along a circumferential closed circular line. Preferably, the contact element contacts both connector elements along a closed circumferential circle. This results in a well-defined contact with good passive intermodulation and RF radiation. A significant advantage of the invention is also that axial angular deviations between the two connector elements do not affect the RF contact to about 1 °. The contact is thus characterized by a high bending stability.

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 has an inner collar and is designed so that there is always an axial residual force or residual stress. This ensures that regardless of the tolerance deviations of the coupling member an axial tension is maintained. The contact element is thus constructed so that it can not evert, 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 the contact element is mounted on the outside of an insulator. This insulator is preferably arranged in the first connector element and arranged between the inner conductor part and the outer conductor part. During assembly, the contact element can be pushed onto this outer conductor in a simple manner. Said collar or the assessment on the inner edge of the contact element facilitates this assembly significantly. Preferably, the contact element is inserted into an outer 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 RF properties arise when, according to an embodiment of the invention, the end face of the outer conductor part of the second connector element is sharpened to a circumferential line-shaped contact surface. The contact area between the contact element and the second connector element is 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 emerge from the dependent claims, the following description and the drawings.

An embodiment of the invention will be explained in more detail with reference to the drawing. Show it:

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.1 shows an electrical connector 1, which has a first connector element 2 and a second connector element 3, which form an outer conductor 9 and an inner conductor 10. The two connector elements 2 and 3 are connected to a coupling member 26 releasably connected to each other. The coupling member 26 has in a conventional manner a locking ring 5 which engages in an outer groove 6 of the second connector element 3 and is present at a shoulder 29 of the first connector element 2 and on a retaining edge 7. In order to release the lock, a locking sleeve 4 is moved in the direction of the arrow 28 and thus in Figure 1 from right to left. With a circumferential inner edge 30 of the locking ring 5 is lifted out of the outer groove 6 and thus solved the lock. When mating the two connector elements 2 and 3, the locking ring 5 automatically engages in the groove 6 a.

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.In order to compensate for the tolerance of the coupling member 26 and to achieve good RF properties, a contact element 16 is provided, which is arranged between an outer conductor part 11 of the first connector element 2 and an outer conductor part 12 of the second connector element 3. The contact element 16 forms a plate spring and has a conical annular disc 23, which has at its edge a collar 22 which extends axially and whose wall thickness is smaller by a multiple than the width of the annular disc 23. The contact element 16 consists of a resilient metal, such as a suitable 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 particularly clearly shown in FIG. 3, the contact element 16 is arranged between an end face 21 of the outer conductor part 12 and a contact surface 20 of the outer conductor part 11. To the outer conductor part 12, the contact element 16 forms a circumferential line-shaped and closed contact surface A. To the outer conductor part 11, the contact element 16 also forms a closed circumferential and circular contact surface B. These two surfaces A and B are radially spaced from one another according to FIG. As can be seen, the front end 12a of the outer conductor part 12 is sharpened on the end side 21, so that the end face 21 bears against the contact element 16 only in the region of the closed circular surface A. In a limiting case, the contact element 16 can be applied flat to the surface 20. Even in this limiting case remains a residual force and thus exerts the contact element 16 in this case, an axial stress on the two outer conductor parts 11 and 12. As a result of the axial tension of the contact element 16, the tolerance of the coupling member 26 is 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 receives in known manner an inner conductor part 13, which is connected according to Figure 1 with a formed as a spring bushing inner conductor part 14. As FIG. 3 shows in particular, a peripheral groove 19, into which the contact element 16 is inserted, is incorporated into the outside of the insulator 15. The contact element 16 is thus mounted on the insulator 15, which is not mandatory. To mount the contact element 16, this is pushed onto the insulator 15, which is substantially facilitated by the collar 22. The placement of 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 sealed with a sealing ring 17 against each other, which is inserted into an inner groove 18 of the outer conductor part 11. As can be seen, this sealing ring 17 bears against the outside of the outer conductor part 12. FIG. 2 shows the first connector element 2 with the contact element 16 in the relaxed rest position. Now, if the second connector element 3 is inserted into the first connector element 2, then the locking ring 5 is spread by the shoulder 7 and this finally engages in the groove 6 a. At the same time, the sealing ring 17 is compressed and the contact element 6 is elastically deformed from the dash-dotted shape shown in FIG. 3 to the shape shown in solid lines. As a result, the contact element 16 is tensioned and exerts an axial force, which presses the locking ring 5 against the shoulder 7 and against the retaining edge 8. When the connection is released, the contact element 16 returns to the rest position shown in FIG.
