Abstract

The invention relates to a coupling device for coaxial plug-in connectors, comprising a plug-in side end (16) for connecting to a coaxial plug-in connector (20), an end facing away from the plug-in side end, especially for connecting to a coaxial cable, a contact sleeve (10), which is configured in the form of a collet chuck (18) at the plug-in end, and an axially moveable locking sleeve (14) that overlaps the collet chuck (18). Said locking sleeve has an unlocking position in which the collet chuck (18) can be expanded and the coaxial plug-in connector (20) can be inserted into the coupling device until the collet chuck (18) snaps into a groove (22) on the coupling device side; and a locking position in which the collet chuck (18) cannot be expanded and the coaxial plug-in connector (20) cannot be detached from the coupling device. According to the invention, the arrangement is such that an end (28) of the locking sleeve (14) facing away from the plug-in side end of the coupling device has at least one radially elastic resilient section (30), which is configured in such a way that it interacts with a surface of the coupling device in such a way that when the locking sleeve (14) is pivoted out of the locking position, the radial pivoting movement of the elastically resilient section (30) of the locking sleeve (14) causes a restoring force to the locking position to be produced.

Description

Die Erfindung betrifft einen Kuppler für einen Koaxialsteckverbinder mit einem steckseitigen Ende zum Verbinden mit einem Koaxialstecker, einem dem steckseitigen Ende abgewandten Ende, insbesondere zum Verbinden mit einem Koaxialkabel, einer Kontakthülse, welche steckseitig als Spannzange ausgebildet ist, und mit einer die Spannzange übergreifenden und axial beweglichen Verriegelungshülse, welche eine Entriegelungsstellung, in der die Spannzange aufweitbar und damit der Koaxialstecker in den Kuppler bis zum Einrasten der Spannzange in eine kupplerseitige Nut einsteckbar ist, und femer eine Verriegelungsstellung aufweist, in der die Spannzange nicht aufweitbar und damit der Koaxialstecker vom Kuppler nicht lösbar ist, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a coupler for a coaxial connector with a plug end for connecting to a coaxial connector, one the plug end End facing away from the end, in particular for connecting with a coaxial cable, a contact sleeve, which is designed as a collet on the plug side, and with an axially movable locking sleeve overlapping the collet, which is an unlocked position in which the collet can be expanded and thus the coaxial connector in the coupler until the collet snaps in a groove on the coupler side can be inserted, and furthermore has a locking position, in which the collet cannot be expanded and thus the coaxial connector from Coupler is not detachable, according to the preamble of claim 1.

Derartige Koax-Steckverbinder mit Schnapp-Mechansimus sind beispielsweise für eine sogn. SMB-Serie in der deutschen Norm DIN EN 122130 beschrieben. Bei diesen Steckverbindungen schnappt eine spannzangenartig ausgebildete Kontakthülse eines Kupplers in eine Rille eines Steckers. Hierdurch ist die Steckverbindung nur durch aufbringen einer entsprechenden Kraft, welche durch die Kraft der Einschnappverbindung bestimmt ist, zu lösen. Es hat sich jedoch gezeigt, daß sich diese Steckverbindung unerwünscht beispielsweise unter Einsfluß von Vibrationen löst. Um dies zu verhindern, ist es bereits bekannt, eine Verriegelungshülse am Kuppler vorzusehen, welche in einer Verriegelungsstellung ein Aufweiten der Spannzange der Kontakthülse des Kupplers verhindert und somit ein herausziehen des Steckers aus dem Kuppler blockiert. Die in diesem Zusammenhang auf dem Markt befindlichen Mechanismen haben jedoch den Nachteil, daß die Verriegelungshülse entweder manuell in die Verriegelungsstellung zu bringen ist oder ein entsprechender Rückstellmechanismus für die Verriegelungshülse viele Einzelteile mit einem komplizierten Aufbau und entsprechend hohen Herstellungsund Montagekosten aufweist.Such coax connectors with snap mechanism are, for example, for a sogn. SMB series described in the German standard DIN EN 122130. at a snap-in contact sleeve snaps these plug connections of a coupler into a groove of a plug. This is the plug connection only by applying a corresponding force, which by the force the snap connection is intended to solve. However, it has been shown that this connector is undesirable, for example, under the influence of vibrations solves. To prevent this, it is already known to use a locking sleeve to be provided on the coupler, which, in a locking position, widens the Prevents collet of the contact sleeve of the coupler and thus pull out the connector from the coupler is blocked. The related in this Mechanisms on the market, however, have the disadvantage that the locking sleeve is to be brought manually into the locking position or a corresponding reset mechanism for the locking sleeve many items with a complicated structure and correspondingly high manufacturing and Assembly costs.

US-A-3 885 851 beschreibt einen Kuppler nach dem Oberbegriff des Anspruchs 1.US-A-3 885 851 describes a coupler according to the Preamble of claim 1.

Diese Aufgabe wird erfindungsgemäß bei einem Kuppler der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is inventively in a coupler of the above. Kind of with the in Characteristics characterized claim 1 solved. Advantageous configurations the invention are described in the further claims.

Erfindungsgemäß ist es bei einem Kuppler der o.g. Art vorgesehen, daß ein dem steckseitigen Ende des Kupplers abgewandtes Ende der Verriegelungshülse wenigstens einen radial elastisch federnden Abschnitt aufweist, welcher derart ausgebildet ist, daß er mit einer Oberfläche des Kupplers derart zusammenwirkt, daß sich bei axialer Auslenkung der Verriegelungshülse aus der Verriegelungsstellung durch radiales Auslenken des elastisch federnden Abschnittes der Verriegelungshülse eine in die Verriegelungsstellung rückstellende Kraft ergibt.According to the invention it is in a coupler of the above. Art provided that a at least the end of the locking sleeve facing away from the plug-side end of the coupler has a radially resilient section which is formed in this way is that it cooperates with a surface of the coupler such that with axial deflection of the locking sleeve from the locking position by radially deflecting the elastically resilient section of the locking sleeve results in a restoring force in the locking position.

Dies hat den Vorteil, daß der Stecker bei automatischer Verriegelung nach dem Einstecken des Koaxialsteckers in den Kuppler wenige Teile aufweist und insbesondere der Mechanismus der automatischen Rückstellung der Verriegelungshülse in die Verriegelungsstellung ausschließlich durch Zusammenwirken von Verriegelungshülse und Kuppler realisiert ist, ohne zusätzliche separate Bauteile. Dies macht den erfindungsgemäßen Kuppler in der Herstellung sowie Montage kostengünstig und einfach sowie funktionssicher in der Handhabung. Die erfindungsgemäße Lösung hat den besonderen Vorteil, daß sie auch bei relativ kleinen Kupplem kostengünstig realisierbar ist.This has the advantage that the plug with automatic locking after Inserting the coaxial connector into the coupler has few parts and in particular the mechanism of the automatic reset of the locking sleeve in the locking position only by the interaction of the locking sleeve and coupler is realized without additional separate components. This makes the coupler according to the invention inexpensive to manufacture and assemble and simple and reliable to use. The invention Solution has the particular advantage that it is also with relatively small couplers is inexpensive to implement.

Zum Erzeugen einer möglichst großen rückstellenden Kraft bei Auslenkung der Verriegelungshülse ist das dem steckseitigen Ende des Kupplers abgewandte Ende der Verriegelungshülse spannzangenartig ausgebildet.To generate the greatest possible restoring force when deflecting the Locking sleeve is the end facing away from the plug end of the coupler the locking sleeve is formed like a collet.

In einer bevorzugten Ausführungsform sind an dem elastisch federnden Abschnitt der Verriegelungshülse ein Nocken und an der Oberfläche des Kupplers im Bereich des Nockens zwei entgegengesetzt abgeschrägte Flächen ausgebildet, welche derart angeordnet und ausgebildet sind, daß der Nocken bei Auslenkung der Verriegelungshülse aus der Verriegelungsstellung je nach axialer Bewegungsrichtung der Verriegelungshülse an einer der schrägen Flächen entlang gleitet und eine Auslenkung des elastisch federnden Abschnitts der Verriegelungshülse bewirkt. Hierbei ist der Nocken bevorzugt einstückig mit der Verriegelungshülse ausgebildet.In a preferred embodiment are on the resilient portion the locking sleeve a cam and on the surface of the coupler in the area of the cam formed two oppositely beveled surfaces, which are arranged and designed such that the cam upon deflection of the Locking sleeve from the locking position depending on the axial direction of movement the locking sleeve slides along one of the inclined surfaces and deflection of the resilient portion of the locking sleeve causes. Here, the cam is preferably formed in one piece with the locking sleeve.

In einer alternativen bevorzugten Ausführungsform sind an der Oberfläche des Kupplers ein Nocken und an dem elastisch federnden Abschnitt der Verriegelungshülse im Bereich des Nockens zwei entgegengesetzt abgeschrägte Flächen ausgebildet, welche derart angeordnet und ausgebildet sind, daß bei Auslenkung der Verriegelungshülse aus der Verriegelungsstellung je nach axialer Bewegungsrichtung der Verriegelungshülse eine der schrägen Flächen über den Nocken gleitet und eine Auslenkung des elastisch federnden Abschnitts der Verriegelungshülse bewirkt. Hierbei sind die schrägen Flächen zweckmäßigerweise einstückig mit der Verriegelungshülse ausgebildet. In an alternative preferred embodiment, the surface of the Coupler a cam and on the resilient portion of the locking sleeve two oppositely beveled surfaces in the area of the cam trained, which are arranged and designed such that upon deflection the locking sleeve from the locking position depending on the axial direction of movement the locking sleeve one of the inclined surfaces above the cam slides and a deflection of the resilient portion of the locking sleeve causes. Here, the inclined surfaces are expediently in one piece formed with the locking sleeve.

Zum Beschränken der axialen Bewegung der Verriegelungshülse weisen bevorzugt die schrägen Flächen Anschlagkanten auf.To limit the axial movement of the locking sleeve preferably have the sloping surfaces.

Für eine kostengünstige und automatisierte Großserienherstellung ist bevorzugt die Verriegelungshülse als Spritzgußteil ausgebildet, wobei die Verriegelungshülse beispielsweise aus Kunststoff hergestellt ist.The locking sleeve is preferred for cost-effective and automated mass production formed as an injection molded part, the locking sleeve for example is made of plastic.

The invention is explained in more detail below with reference to the drawing. This shows in:

Die in Fig. 1 dargestellte bevorzugte Ausführungsform eines erfindungsgemäßen Kupplers umfaßt eine Kontakthülse 10, einen Mittelleiter 12 und eine Verriegelungshülse 14. Die Kontakthülse 10 ist an einem steckseitigen Ende mit einer Spannzange 18 ausgebildet, in die ein mit gestrichelten Linien angedeuteter Stekker 20 einsteckbar ist. Der Innendurchmesser der Spannzange 18 und der Außendurchmesser des Steckers 20 sind derart dimensioniert, daß zum Einstecken des Steckers 20 die Spannzange 18 aufgeweitet werden muß. Der Stecker 20 weist femer eine umlaufende Rille 22 auf, in die bei vollständig in die Kontakthülse 10 eingestecktem Stecker 20 die Spannzange 18 einschnappt und somit einen gewissen Widerstand gegen ein Lösen von Stecker 20 und Kontakthülse 10 zur Verfügung stellt.The preferred embodiment shown in Fig. 1 of an inventive Coupler includes a contact sleeve 10, a central conductor 12 and a locking sleeve 14. The contact sleeve 10 is at one end with a plug Collet 18 formed, in which a plug indicated with dashed lines 20 can be inserted. The inside diameter of the collet 18 and the outside diameter of the connector 20 are dimensioned such that for insertion of the plug 20, the collet 18 must be expanded. The connector 20 also has a circumferential groove 22, in the completely in the contact sleeve 10 inserted plug 20 snaps the collet 18 and thus one certain resistance to loosening of connector 20 and contact sleeve 10 for Provides.

Die Verriegelungshülse 14 ist an ihrem steckseitigen Ende 16 derart ausgebildet, daß sie in einer in Fig. 1 dargestellten Verriegelungsstellung ein Aufweiten der Spannzange 18 und somit ein Ein- bzw. Ausstecken des Steckers 20 verhindert. Hierzu weist die Verriegelungshülse 14 im Bereich 24 eine entsprechende Erhebung 26 auf, an die entsprechende Segmente der Spannzange 18 anschlagen, wenn sich die Verriegelungshülse 14 in der in Fig. 1 dargestellten Verriegelungsstellung befindet. Durch dieses Anschlagen der Segmente der Spannzange 18 ist ein aufweiten derselben verhindert und ein Ein- bzw. Ausstecken des Steckers 20 blockiert.The locking sleeve 14 is formed at its plug-side end 16 in such a way that they expand in a locking position shown in Fig. 1 Collet 18 and thus prevents the plug 20 from being inserted or removed. For this purpose, the locking sleeve 14 has a corresponding elevation in the area 24 26, strike the corresponding segments of the collet 18, when the locking sleeve 14 in the locking position shown in Fig. 1 located. By striking the segments of the collet 18 is prevents the same from expanding and plugging or unplugging the plug 20 blocked.

An einem dem steckseitigen Ende des Kupplers abgewandten Ende 28 weist die Verriegelungshülse 14 mehrere elastisch federnde Abschnitte 30 auf, welche um den Umfang der Verriegelungshülse 14 herum spannzangenartig angeordnet sind. Die elastisch federnden Abschnitte 30 sind derart ausgebildet, daß sie bezüglich des Kupplers in radialer Richtung elastisch federnd ausgelenkt werden können. Jeder elastisch federnde Abschnitt 30 weist einen Nocken 32 auf, der in eine Ausnehmung 34 in der Kontakthülse 10 des Kupplers greift Die Ausnehmung 34 ist mit zwei schrägen Flächen 36 derart ausgebildet, daß bei Auslenkung der Verriegelungshülse 14 aus der in Fig. 1 dargestellten Verriegelungsstellung der Nocken 32 entlang einer jeweiligen schrägen Fläche 36 gleitet und dadurch zu einer Auslenkung der elastisch federnden Abschnitte 30 der Verriegelungshülse 14 führt. Auf diese Weise ergibt sich eine rückstellende Kraft, welche die Verriegelungshülse 14 nach dem Loslassen dieser automatisch wieder in die in Fig. 1 dargestellte Verriegelungsstellung zurückbewegt.At an end 28 facing away from the plug-side end of the coupler, the Locking sleeve 14 on a plurality of resilient sections 30, which around the circumference of the locking sleeve 14 are arranged like collets. The resilient portions 30 are formed such that they are of the coupler can be deflected elastically resilient in the radial direction. Each elastically resilient section 30 has a cam 32 which is in a recess 34 engages in the contact sleeve 10 of the coupler. The recess 34 is formed with two inclined surfaces 36 such that when the locking sleeve is deflected 14 from the locking position of the cams shown in FIG. 1 32 slides along a respective inclined surface 36 and thereby to a deflection the resilient portions 30 of the locking sleeve 14 leads. In this way, there is a restoring force which the locking sleeve 14 automatically after releasing this back into that shown in Fig. 1 Lock position moved back.

Wie sich unmittelbar aus Fig. 1 ergibt, ist somit erfindungsgemäß ein Rückstellmechanismus für die Verriegelungshülse 14 in die Verriegelungsstellung realisiert, bei dem ausschließlich die Verriegelungshülse 14 mit der Kontakthülse 10 zusammenwirkt, ohne zusätzliche separate Teile. Die axiale Bewegung der Verriegelungshülse 14 auf der Kontakthülse 10 ist durch entsprechende Anschläge 38 der Ausnehmung 34 an den Enden der schrägen Flächen 36 begrenzt. An diesen Anschlägen 38 schlagen die Nocken 32 bei entsprechender Auslenkung der Verriegelungshülse 14 an und die Verriegelungshülse 14 ist axial nicht mehr weiter bewegbar.As can be seen directly from FIG. 1, a reset mechanism is thus according to the invention realized for the locking sleeve 14 in the locking position, at which only the locking sleeve 14 interacts with the contact sleeve 10, without additional separate parts. The axial movement of the locking sleeve 14 on the contact sleeve 10 is the corresponding stops 38 of the Recess 34 limited at the ends of the inclined surfaces 36. At these attacks 38 strike the cams 32 with a corresponding deflection of the locking sleeve 14 on and the locking sleeve 14 is no longer axially movable.

Fig. 2 veranschaulicht eine erste Entriegelungsstellung der Verriegelungshülse 14 zum Einstecken des Steckers 20 in die Kontakthülse 10 unter gleichzeitigem Aufweiten und Einschnappen der Spannzange 18 in die Rille 22. Hierbei ist die Verriegelungshülse 14 manuell in Richtung des steckseitigen Endes 16 des Kupplers verschoben, so daß die entsprechenden Segmente der Spannzange 18 in radialer Richtung einen Freigang zur Aufweitung der Spannzange aufweisen. Hierbei wird zum Einstecken der Kuppler manuell mit der Hand im Bereich der Verriegelungshülse 14 gegriffen und der Stecker 20 sowie der Kuppler gegeneinander gedrückt, so daß auf die Verriegelungshülse 14 eine Kraft in Richtung Pfeil 40 ausgeübt wird. Durch die sich dadurch ergebende axiale Verschiebung der Verriegelungshülse 14 in Richtung des steckseitigen Endes 16 des erfindungsgemäßen Kupplers gleiten die Nocken 32 entlang der schrägen Flächen 36 und führen so zu der aus Fig. 2 ersichtlichen elastischen Auslenkung der elastisch federnden Abschnitte 30. Die Nocken 32 und damit die Verriegelungshülse 14 stehen dementsprechend unter einer Vorspannung, welche eine rückstellende Kraft in Richtung der Verriegelungsstellung bewirkt. Sobald der Stecker 20 vollständig in die Kontakthülse 10 eingeschoben ist und die Spannzange 18 in die Rille 22 des Steckers 20 einschnappt, kann die Verriegelungshülse 14 losgelassen werden, woraufhin die rückstellende Kraft die Verriegelungshülse 14 automatisch in die Verriegelungsstellung gemäß Fig. 1 axial zurück bewegt Diese Kraft wird hierbei durch die ausgelenkten Abschnitte 30 der Verriegelungshülse 14 erzeugt.2 illustrates a first unlocking position of the locking sleeve 14 for inserting the plug 20 into the contact sleeve 10 with simultaneous expansion and snapping the collet 18 into the groove 22. Here is the locking sleeve 14 manually in the direction of the plug end 16 of the coupler moved so that the corresponding segments of the collet 18 in radial Direction have an opening to widen the collet. Here will to insert the coupler manually by hand in the area of the locking sleeve 14 gripped and the connector 20 and the coupler pressed against each other, so that a force in the direction of arrow 40 is exerted on the locking sleeve 14 becomes. Due to the resulting axial displacement of the locking sleeve 14 in the direction of the plug end 16 of the coupler according to the invention the cams 32 slide along the inclined surfaces 36 and thus lead to the 2 apparent elastic deflection of the resilient portions 30. The cams 32 and thus the locking sleeve 14 are accordingly under a bias, which is a restoring force towards the locking position. Once the connector 20 is fully in the contact sleeve 10 is inserted and the collet 18 in the groove 22 of the connector 20 snaps, the locking sleeve 14 can be released, whereupon the restoring force the locking sleeve 14 automatically into the locking position 1 axially moved back This force is here by the deflected portions 30 of the locking sleeve 14 generated.

Fig. 3 zeigt eine zweite Entriegelungsstellung der Verriegelungshülse 14 zum Lösen der Koaxialsteckverbindung und zum Herausziehen des Steckers 20 aus der Kontakthülse 10. Hierbei werden der Stecker 20 und die Verriegelungshülse 14 manuell ergriffen und voneinander weggezogen, wodurch sich eine lösende Kraft in Richtung Pfeil 42 ergibt. Durch diese Kraft wird die Verriegelungshülse 14 in Richtung eines dem steckseitigen Ende 26 abgewandten Ende des Kupplers axial verschoben und die Segmente der Spannzange 18 haben einen entsprechenden Freigang in radialer Richtung zum Aufweiten der Spannzange 18, so daß sie aus der Rille 22 des Steckers 20 herausgezogen werden können. Gleichzeitig ergibt sich durch die auf den Schrägen 36 entlang gleitenden Nocken 32 wiederum eine entsprechende rückstellende Kraft, welche die Verriegelungshülse 14 in Richtung der Verriegelungsstellung gemäß Fig. 1 mit einer Vorspannung beaufschlagt. Sobald nun der Stecker 20 vollständig aus der Kontakthülse 10 herausgezogen ist, kann die Verriegelungshülse 14 losgelassen werden, woraufhin unter der rückstellenden Kraft aufgrund der elastisch ausgelenkten Abschnitte 30 die Verriegelungshülse 14 automatisch in die Verriegelungsstellung gemäß Fig. 1 in axialer Richtung zurückgleitet.Fig. 3 shows a second unlocking position of the locking sleeve 14 for releasing the coaxial connector and for pulling the plug 20 out of the Contact sleeve 10. Here, the connector 20 and the locking sleeve 14th manually gripped and pulled away from each other, creating a releasing force results in the direction of arrow 42. By this force, the locking sleeve 14 in Direction of an end of the coupler facing away from the plug-side end 26 axially moved and the segments of the collet 18 have a corresponding Clearance in the radial direction to expand the collet 18 so that it is out the groove 22 of the plug 20 can be pulled out. At the same time results through the cams 32 sliding along the slopes 36 in turn corresponding restoring force which the locking sleeve 14 in the direction the locking position shown in FIG. 1 with a bias. As soon as now the plug 20 is completely pulled out of the contact sleeve 10, the locking sleeve 14 can be released, whereupon under the resetting Force due to the elastically deflected sections 30, the locking sleeve 14 automatically in the locking position shown in FIG. 1 in the axial Direction slides back.

Wie sich aus dem Vorangegangenen unmittelbar ergibt, wird beim manuellen Zusammenstecken von Kuppler und Stecker 20 bei Halten des Kupplers an der Verriegelungshülse 14 diese automatisch durch die manuell aufgebrachte Kraft (Pfeile 40 bzw. 42) automatisch in die richtige Entriegelungsstellung gemäß Fig. 2 oder Fig. 3 verschoben und bewegt sich nach dem Einstecken des Steckers 20 in den Kuppler bzw. nach dem Lösen des Steckers 20 aus dem Kuppler selbsttätig zurück in die Verriegelungsstellung gemäß Fig. 1, in der ein unerwünschtes Lösen der Steckverbindung, beispielsweise durch Vbrationen, wirksam verhindert ist. Daher entspricht die zum jeweiligen Entriegeln für ein Ein- bzw. Ausstecken des Steckers 20 erforderliche Bewegungsrichtung der Verriegelungshülse 14 gleichzeitig einer Richtung einer entsprechenden manuell zwischen Kuppler und Stecker 20 aufgebrachten Kraft zum Ein- bzw. Ausstecken. Somit ist der erfindungsgemäße Kuppler intuitiv und ohne besondere Aufmerksamkeit zum Herstellen oder Lösen einer Koaxialsteckverbindung handhabbar, wobei sich der Benutzer insbesondere über die erforderliche Entriegelungsstellung der Verriegelungshülse 14 keine Gedanken zu machen braucht Die richtige Entriegelungsstellung ergibt sich automatisch beim Zusammendrücken von Kuppler und Stecker 20 beim Herstellen der Koaxialsteckverbindung wie auch beim Auseinanderziehen von Kuppler und Stecker 20 zum Lösen der Koaxialsteckverbindung.As can be seen directly from the foregoing, when plugging in manually of coupler and connector 20 while holding the coupler on the locking sleeve 14 this automatically by the manually applied force (arrows 40 or 42) automatically into the correct unlocking position according to FIG. 2 or Fig. 3 shifted and moves after inserting the plug 20 in the Coupler or after loosening the connector 20 from the coupler automatically back 1, in which an undesired release the plug connection, for example by vbrations, is effectively prevented. Therefore corresponds to the respective unlocking for inserting or removing the Connector 20 required direction of movement of the locking sleeve 14 simultaneously one direction of a corresponding manually between coupler and connector 20 applied force for insertion and removal. Thus is the invention Couplers intuitive and without special attention to manufacture or release a coaxial connector can be handled, the user in particular about the required unlocking position of the locking sleeve 14 no need to worry The correct unlocking position results automatically when the coupler and connector 20 are pressed together during manufacture the coaxial connector as well as when pulling the coupler and Plug 20 to release the coaxial connector.

Darüber hinaus ist die Steckverbindung auch manuell nur durch bewußt entsprechendes Halten des Kupplers an der Verriegelungshülse 14 lösbar, da andernfalls auch bei Kraftaufwendung zwischen Kuppler und Stecker 20 in Löserichtung 42 (Fig. 3) die Verriegelungshülse 14 in der Verriegelungsstellung gemäß Fig. 1 verbleibt und ein Lösen des Steckers 20 aus der Spannzange 18 der Kontakthülse 10 verhindert ist. Mit anderen Worten ist ein Abziehen des Kupplers vom Stecker 20 durch versehentliche Zugbelastung auf das am Kuppler befestigte Koaxialkabel verhindert.In addition, the plug connection is also manually only by consciously corresponding Holding the coupler on the locking sleeve 14 releasably, otherwise even when force is applied between the coupler and the plug 20 in the release direction 42 (Fig. 3) the locking sleeve 14 remains in the locking position shown in FIG. 1 and releasing the plug 20 from the collet 18 of the contact sleeve 10 is prevented. In other words, the coupler is removed from the connector 20 due to accidental tensile load on the coaxial cable attached to the coupler prevented.

Eine bevorzugte Ansführung erzielt mit nur einem einzigen Teil, nämlich den am Abschnitt 30 ausgebildeten Nocken 32, eine axiale automatische Rückstellungsbewegung in die Verriegelungsstellung aus beiden Auslenkungsrichtungen. Dies wird dadurch erreicht, daß die radial ausfedemden Nocken 32 an der Verriegelungshülse 14 durch Andruck an die Schrägen 36 an der Kontakthülse 10 abgleiten und dadurch die Verriegelungshülse 14 wieder in die Verriegelungsstellung zurück bewegen.A preferred citation achieved with only one part, namely the cam 32 formed on section 30, an axial automatic return movement in the locking position from both directions of deflection. This is achieved in that the radially rebounding cams 32 on the Locking sleeve 14 by pressing against the bevels 36 on the contact sleeve 10 slide and thereby the locking sleeve 14 back into the locking position move back.
