Aus dem Stand der Technik, beispielsweise aus der DE 198 30 182 A1 sind Steckverbinder bekannt, bei denen ein Verriegelungshebel so ausgestaltet ist, dass er an einem Lagerzapfen schwenkbar gelagert sind. Wie beispielsweise aus der DE 196 33 827 C1 bekannt, kann der Verriegelungshebel mit einem Auge versehen sein, welches in eine gabelartige Lagerungsöffnung übergeht. Es sind darüber hinaus Verriegelungshebel bekannt, an deren Innenseite ein Federelement angebracht ist, welches ein Lagerauge am Verriegelungshebel derart verkleinert, dass es immer eng am Lagerzapfen anliegt.From the prior art, for example from DE 198 30 182 A1 are Connector known, in which a locking lever is designed, that it is pivotally mounted on a bearing pin. Like, for example DE 196 33 827 C1, the locking lever can with one eye be provided, which merges into a fork-like storage opening. There are In addition, locking lever known, on the inside of a spring element is attached, which is a bearing eye on the locking lever such reduced, that it always fits tightly on the journal.

Aus der DE 100 06 433 A1 ist schließlich ein Steckverbinder mit einem Verriegelungshebel bekannt, bei welchem der Verriegelungshebel mit Hilfe von zwei Lagerarmen an einem Lagerzapfen drehbar gelagert ist. Die Lagerarme sind nach Art von Lappen aus einer den Verriegelungshebel bildenden Platte ausgeschnitten. Zusätzlich zu diesen beiden Lagerarmen ist aus der den Verriegelungshebel bildenden Platte noch eine als Blattfeder wirkende Sicherungsfeder ausgeschnitten. Die Vielzahl dieser nach Art von Lappen ausgeschnittenen Funktionsteile führt zu einer konstruktiv unerwünscht aufwendigen Bauteilgeometrie.From DE 100 06 433 A1, finally, a connector with a locking lever known, wherein the locking lever by means of two Bearing arms is rotatably mounted on a bearing journal. The bearing arms are after Type of cloth cut out of a locking lever forming plate. In addition to these two bearing arms is out of the locking lever forming plate still cut out as a leaf spring acting locking spring.

Durch die federnde Ausgestaltung können Toleranzen zwischen Steckteil und Basisteil des Steckverbinders ausgeglichen werden. Im fertig verrasteten Zustand des Verriegelungshebels übt der Lagerschenkel eine Federkraft auf die Konstruktion aus. Dadurch wird ein versehentliches Öffnen des Verriegelungshebels verhindert. Durch die einstückige, integrale Ausführung des Verriegelungshebels wird eine Vereinfachung in baulicher Hinsicht erreicht.The inventive design of the locking lever is a secure engagement of the locking leg when closing the connector allows. Due to the resilient design tolerances be compensated between plug-in part and base part of the connector. in the finished latched state of the locking lever exercises the bearing leg one Spring force on the construction. This will cause accidental opening of the Locking lever prevents. Due to the one-piece, integral design of the Locking lever is achieved a simplification in terms of construction.

Die Rastsicherheit des nach Anspruch 2 für ein Hintergreifen des Verriegelungszapfens ausgebildeten Verschlussschenkels wird durch Anspruch 3 noch verbessert. Ebenso verbessert Anspruch 5 die Rastsicherheit des Lagerschenkels. Die Ausbildung nach Anspruch 6 schützt vor versehentlicher Überbeanspruchung des Federarms, wodurch die Funktionssicherheit des Verriegelungshebels verbessert wird. Durch die Verwendung eines speziellen Federwerkstoffes nach Anspruch 9 wird die Erzielung einer Federwirkung erleichtert. Die Bildung von Verriegelungsbügeln nach Anspruch 11 führt zu einer weiteren Vereinfachung der Bedienung des elektrischen Steckverbinders.The latching safety of claim 2 for engaging behind the locking pin trained closure leg is further improved by claim 3. Likewise, claim 5 improves the safety of the bearing leg. The embodiment of claim 6 protects against accidental overuse the spring arm, whereby the reliability of the locking lever improves becomes.

In Fig. 1 ist ein Verriegelungsbügel für einen elektrischen Steckverbinder 1 dargestellt. Der Verriegelungsbügel 2 ist vorzugsweise symmetrisch aufgebaut und besteht aus zwei im wesentlichen parallel zueinander angeordneten Verriegelungshebeln 3, die durch ein Querjoch 4 miteinander verbunden sind. Der Verriegelungshebel 3 ist ein einstückiges, integrales Bauteil, das vorzugsweise plattenförmig ausgestaltet ist. Er umfaßt einen Lagerschenkel 5 und einen Verschlußschenkel 6.In Fig. 1, a locking bracket for an electrical connector 1 is shown. The locking bracket 2 is preferably constructed symmetrically and consists of two locking levers arranged essentially parallel to one another 3, which are interconnected by a transverse yoke 4. The locking lever 3 is a one-piece, integral component, preferably is designed plate-shaped. It comprises a bearing leg 5 and a Locking leg 6.

Der Lagerschenkel 5 ist derart ausgestaltet, daß er zwei, vorzugsweise lappenförmige, Lagerarme 7, 8 ausbildet. Die Lagerarme 7, 8 können beispielsweise durch Schlitzen des Lagerschenkels 5 oder durch Freischneiden oder ein sonstiges Herausarbeiten eines Lagerarms oder beider Lagerarme aus dem Lagerschenkel 5 gebildet werden. Für ein Ausbilden des oder der Lagerarme aus dem Lagerschenkel können beispielsweise Schneid-, Fräs- oder Stanzverfahren in Betracht kommen. In dem Fall, daß nur ein Lagerarm 8 freigeschnitten wird, dient ein Teil des Lagerschenkels 5 als zweiter Lagerarm 7. Die aus dem Lagerschenkel 5 ausgebildeten Lagerarme 7, 8 liegen im wesentlichen in einer Ebene.The bearing leg 5 is designed such that it has two, preferably flap-shaped, Bearing arms 7, 8 trains. The bearing arms 7, 8, for example by slitting the bearing leg 5 or by free cutting or a Other working out of a bearing arm or both bearing arms of the Bearing leg 5 are formed. For forming the one or more bearing arms The bearing leg can, for example, cutting, milling or punching be considered. In the case that only one bearing arm 8 is cut free, Part of the bearing leg 5 serves as a second bearing arm 7. The out of the bearing leg 5 trained bearing arms 7, 8 are substantially in one plane.

Der Verriegelungshebel 3 ist an einem Basisteil 9 des Steckverbinders 1 schwenkbar gelagert. Dabei bilden die Lagerarme 7, 8 ein Drehgelenk zur Lagerung des Verriegelungshebels 3 an einem Lagerzapfen 10 an dem Basisteil 9 des Steckverbinders 1. Wie aus Fig.2 und Fig.3 erkennbar, umgreifen die Lagerarme 7, 8 den Lagerzapfen 10 zumindest teilweise. Fig.2 zeigt ein Basisteil 9 eines Steckverbinders 1 mit zwei Verriegelungshebeln 3 in Öffnungsstellung. In dieser Stellung liegen die Lagerarme 7, 8 eng an dem Lagerzapfen 10 an und ermöglichen einen festen Halt des Verriegelungshebels 3 an dem Lagerzapfen 10. Die Lagerarme 7, 8 sind zur Aufnahme des Lagerzapfens 10 ausgemuldet. Der Radius der Ausmuldungen 11 entspricht dabei vorzugsweise dem Durchmesser des Lagerzapfens 10.The locking lever 3 is pivotable on a base part 9 of the connector 1 stored. The bearing arms 7, 8 form a hinge for supporting the Locking lever 3 on a bearing pin 10 on the base part 9 of the connector 1. As can be seen from Fig.2 and Fig.3, embrace the bearing arms 7, 8th the journal 10 at least partially. 2 shows a base part 9 of a connector 1 with two locking levers 3 in the open position. In this Position are the bearing arms 7, 8 close to the journal 10 and allow a firm grip of the locking lever 3 on the journal 10. The Bearing arms 7, 8 are tolerated for receiving the journal 10. Of the Radius of the Ausmuldungen 11 corresponds preferably to the diameter of the journal 10.

Zum Schließen des elektrischen Steckverbinders 1 wird ein Steckteil 12 in Steckrichtung 13 auf das Basisteil 9 gesteckt, wobei zwischen beiden Teilen eine elastische Dichtung (nicht dargestellt) einliegt. Anschließend werden die an dem Basisteil 9 gelagerten Verriegelungshebel 3 mit dem Steckteil 12 verrastet. Beim Schließen des Rastverschlusses wird der Verriegelungshebel 3 in einer Ebene verschwenkt, die etwa parallel zu der Mittellängsachse des Steckverbinders 1 ausgerichtet ist.To close the electrical connector 1 is a plug-in part 12 in the insertion direction 13 is placed on the base part 9, wherein between the two parts elastic seal (not shown) rests. Then the at the Base part 9 mounted locking lever 3 locked with the male part 12. At the Closing the snap closure, the locking lever 3 in a plane pivoted, which is approximately parallel to the central longitudinal axis of the connector. 1 is aligned.

Wie man in Fig.3 erkennen kann, ist der Verschlußschenkel 6 derart ausgebildet, daß er beim Schließen des Rastverschlusses einen Verriegelungszapfen 14 am Steckteil des Steckverbinders hintergreift. Der in Fig.3 rechts dargestellte Verriegelungshebel 3 illustriert einen Zeitpunkt während des Verrastens des Verschlußschenkels 6, bei dem die Verriegelung fast geschlossen ist. Man erkennt das Überreiten des Verschlußschenkels 6 über den Verriegelungszapfen 14 am Steckteil 12 des Steckverbinders 1.As can be seen in Figure 3, the locking leg 6 is formed such that when closing the latching closure a locking pin 14 on Plug-in part of the connector engages behind. The locking lever shown on the right in Figure 3 3 illustrates a time during the latching of the locking leg 6, where the lock is almost closed. One recognises the riding over the locking leg 6 via the locking pin 14 on Plug-in part 12 of the connector 1.

Ein Lagerarm des Lagerschenkels 5 des Verriegelungshebels 3 ist als Federarm 8 ausgebildet. Der Federarm 8 ist dabei derart ausgestaltet, daß der Verriegelungshebel 3 zum Verrasten und Entrasten des Verschlußschenkels 6 gegen die Federkraft des Federarms 8 gegenüber dem Basisteil 9 in Richtung auf das Steckteil 12 verschoben werden kann. Dadurch wird ein sehr sicheres Schließen und Öffnen der Verriegelung ermöglicht. Die Stärke der Federwirkung des Federarms 8 kann durch verschiedene konstruktive Maßnahmen, wie beispielsweise eine Änderung der Stärke des Federarmfußes eingestellt werden. Durch die Auslenkung des Federarms 8 bei der Verschiebung des Verriegelungshebels 3 in Richtung auf das Steckteil 12 wird die Umgreifung des Lagerzapfens 10 durch die Lagerarme 7, 8 derart verändert, daß nun lediglich der Federarm 8 an dem Lagerzapfen 10 anliegt. Das vom Lagerzapfen 10 und dem Lagerarm 7 einerseits und dem Federarm 8 andererseits gebildete Gelenk wirkt somit als Dreh-Schubgelenk.A bearing arm of the bearing leg 5 of the locking lever 3 is as a spring arm. 8 educated. The spring arm 8 is designed such that the locking lever 3 for locking and unlatching of the locking leg 6 against the spring force the spring arm 8 relative to the base part 9 in the direction of the male part 12th can be moved. This will be a very safe closing and opening the lock allows. The strength of the spring action of the spring arm 8 can through various design measures, such as a change the strength of the Federarmfußes be adjusted. Due to the deflection of the Spring arm 8 during the displacement of the locking lever 3 in the direction of the Plug-in part 12 is the encircling of the bearing pin 10 by the bearing arms 7, the eighth changed so that now only the spring arm 8 rests on the bearing pin 10. The bearing pin 10 and the bearing arm 7 on the one hand and the spring arm On the other hand formed joint thus acts as a rotary sliding joint.

Vorzugsweise weist der Verriegelungshebel 3 einen weiteren, aus dem Lagerschenkel 5 ausgebildeten Anschlagsarm 15 auf, der bevorzugt auf gleiche Art und Weise wie die Lagerarme 7, 8 aus dem Lagerschenkel 5 gebildet wird. Wie in Fig. 3 (rechts) gezeigt, ist dieser so ausgebildet, daß er einen Anschlag für den Federarm 8 bildet, um bei einer Auslenkung des Federarms 8 den Federweg zu begrenzen. Die Gefahr des Brechens oder Überdehnens des Federarms 8 durch eine übergroße Auslenkung wird dadurch verringert.Preferably, the locking lever 3 has another, from the bearing leg 5 trained stop arm 15, preferably in the same way and How the bearing arms 7, 8 is formed from the bearing leg 5. As in Fig. 3 (right), this is designed so that it has a stop for the Spring arm 8 forms to the spring travel at a deflection of the spring arm 8 limit. The risk of breaking or overstretching of the spring arm 8 by an oversized deflection is thereby reduced.

Der in Fig.3 links dargestellte Verriegelungshebel 3 zeigt eine vollständig geschlossene Verriegelung. Dabei ist der Verschlußschenkel 6 des Verriegelungshebels 3 durch ein Hintergreifen des Verriegelungszapfens 14 mit dem Steckteil 12 verrastet. Das Prinzip des Verriegelungshebels 3 beruht darauf, daß jetzt zwischen dem Verschlußschenkel 6 und dem Verriegelungszapfen 14 einerseits und zwischen dem Federarm 8 und dem Lagerzapfen 10 andererseits eine Federdruckanlage besteht, die die Verriegelung sichert und einen Anpreßdruck auf die elastische Dichtung (nicht dargestellt) zwischen Basisteil 9 und Steckteil 12 ausübt. Vorzugsweise ist der Verschlußschenkel 6 zum Hintergreifen des Verriegelungszapfens 14 ausgemuldet. Der Radius der Ausmuldung 16 entspricht dabei vorzugsweise dem Durchmesser des Verriegelungszapfens 14.The locking lever 3 shown on the left in Figure 3 shows a completely closed Locking. In this case, the locking leg 6 of the locking lever 3 by engaging behind the locking pin 14 with the male part 12 locked. The principle of the locking lever 3 is based on that now between the locking leg 6 and the locking pin 14 on the one hand and between the spring arm 8 and the bearing pin 10 on the other hand, a spring pressure system exists, which secures the lock and a contact pressure on the elastic seal (not shown) between the base part 9 and plug-in part 12 exerts. Preferably, the locking leg 6 for engaging behind the locking pin 14 tolerated. The radius of the Ausmuldung 16 corresponds preferably the diameter of the locking pin 14.

Lagerzapfen 10 und Verriegelungszapfen 14 sind hinsichtlich ihrer Ausbildung und Anordnung an Basisteil 9 und Steckteil 12 des Steckverbinders 1 identisch. Daher kann der Verriegelungshebel 3 wahlweise auch an dem Verriegelungszapfen 14 lagerbar sein. In diesem Fall übernimmt der Lagerzapfen 10 die Funktion eines Verriegelungszapfens. Dadurch ist es weiterin möglich, verschiedene Steckteile 12 auf ein und dasselbe Basisteil 9 zu stecken. Durch die federnde Ausgestaltung des Verriegelungshebels 3, die einen Toleranztausgleich ermöglichen, sind unter Umständen auch Basisteile und Steckteile verschiedener Hersteller miteinander kombinierbar.Journal 10 and locking pin 14 are in terms of their training and Arrangement on the base part 9 and plug-in part 12 of the connector 1 identical. Therefore can the locking lever 3 optionally also on the locking pin 14th be storable. In this case, the bearing pin 10 assumes the function of Locking pin. This makes it possible to use different plug-in parts 12 stuck on one and the same base part 9. Due to the resilient design of the locking lever 3, which allow a tolerance compensation, are under Circumstances also basic parts and plug-in parts from different manufacturers together combined.

Zum sicheren Verbinden von Basisteil 9 und Steckteil 12 eines Steckverbinders 1 wird mindestens ein Verriegelungshebel 3 verwendet. Durch die Verbindung von mehreren Verriegelungshebeln 3 zu Verriegelungsbügeln 2 wie sie in Fig. 1 - 3 dargestellt sind, wird die Handhabung weiter vereinfacht. Verriegelunghebel 3 und Verriegelungsbügel 2 können auch mit anderen Befestigungsmitteln kombiniert werden. For secure connection of the base part 9 and plug-in part 12 of a connector. 1 At least one locking lever 3 is used. Through the connection of a plurality of locking levers 3 to lock brackets 2 as shown in Fig. 1-3 are shown, the handling is further simplified. Lock lever 3 and Locking bracket 2 can also be combined with other fastening means become.

Der Verriegelungshebel 3 besteht vorzugsweise aus einem Werkstoff mit federnden Eigenschaften. Insbesondere kommt die Verwendung von Federstahl in Betracht. Aber auch die Verwendung von anderen Werkstoffen, wie beispielsweise Kunststoffen, ist möglich. Wird ein Verriegelungsbügel 2 verwendet, so kann dieser vollständig aus einem solchen Werkstoff gefertigt sein.The locking lever 3 is preferably made of a material with resilient Properties. In particular, the use of spring steel comes in Consideration. But also the use of other materials, such as Plastics, is possible. If a locking bracket 2 is used, then this can be made entirely of such a material.

Durch die integrale Ausgestaltung des Verriegelungshebels 3 ist es nicht notwendig, zusätzliche Bauteile, beispielsweise Federn o.ä., für ein sicheres Verrasten und Entrasten vorzusehen. Sämtliche Funktionen des Verriegelungshebels 3 werden durch ein einziges integrales Bauteil erfüllt. Dadurch können die Herstellungskosten von elektrischen Steckverbindern 1 gesenkt werden. Durch die integrale Ausgestaltung ist es möglich, sowohl einen Verriegelungshebel 3 als auch einen ganzen Verriegelungsbügel 2 durch einfache Bearbeitungsverfahren wie Umformtechniken, beispielsweise Biegeumformung, aus einem einzigen vorzugsweise plattenförmigen Rohling , beispielsweise einen Blechumformteil herzustellen, wodurch die Herstellungskosten weiter gesenkt werden können.Due to the integral design of the locking lever 3, it is not necessary additional components, such as springs or the like, for a secure locking and unlatching provided. All functions of the locking lever 3 are fulfilled by a single integral component. This can reduce the manufacturing costs be lowered by electrical connectors 1. By the integral design, it is possible both a locking lever 3 as also a whole locking bracket 2 by simple processing methods as forming techniques, such as bending forming, from a single preferably plate-shaped blank, for example, a sheet metal forming part manufacture, whereby the manufacturing cost can be further reduced.

Zum Zweck des Verschwenkens des Verriegelungshebels 3 kann an dem dem Lagerschenkel 5 abgewandten Ende des Verriegelungshebels 3 eine Handhabe 17 angebracht sein. Diese kann beispielsweise integral mit dem Verriegelungshebel 3 verbunden sein oder aus einem zusätzlichen Bauteil bestehen, das an dem Verriegelungshebel 3 angebracht ist. In dem Fall, daß zwei Verriegelungshebel 3 zu einem Verriegelungsbügel 2 verbunden sind, sind vorzugsweise sowohl die beiden Verriegelungshebel 3 als auch das Querjoch 4, das die Verriegelungshebel 3 an dem dem Lagerschenkel 5 abgewandten Ende miteinander verbindet, aus einem einstückigen, integralen Bauteil gefertigt. Das Querjoch 4 kann aber auch aus einem weiteren Bauteil bestehen, das mit den Verriegelungshebeln 3 verbunden ist. Das Querjoch 4 kann weiterhin derart ausgestaltet sein, daß es die Funktion einer Handhabe übernimmt. Die Handhabe 17 kann auch als ein zusätzliches Bauteil an dem Querjoch 4 befestigt sein. Zur Verbesserung der Handhabbarkeit kann die Anbringung eines weiteren Bauteils, beispielsweise eines Überzugs aus einem Kunststoffmaterial, vorgesehen sein. For the purpose of pivoting the locking lever 3 can at the Bearing leg 5 opposite end of the locking lever 3 a handle 17 be attached. This can for example be integral with the locking lever Be connected 3 or consist of an additional component, the the locking lever 3 is mounted. In the case that two locking levers 3 are connected to a locking bracket 2 are preferably both the two locking lever 3 and the transverse yoke 4, which is the locking lever 3 at the end facing away from the bearing leg 5 with each other connects, made of a one-piece, integral component. The cross yoke 4 but can also consist of another component, with the locking levers 3 is connected. The transverse yoke 4 can continue to be designed in this way be that it takes over the function of a handle. The handle 17 can be attached as an additional component to the cross yoke 4. For improvement the handling can be the attachment of another component, for example a coating of a plastic material may be provided.

Die Erfindung betrifft einen elektrischen Steckverbinder 1 mit mindestens einem an einem Basisteil 9 des Steckverbinders 1 gelagerten Verriegelungshebel 3, der als ein einstückiges, integrales Bauteil derart ausgestaltet ist, daß ein als Federarm 8 ausgeprägter Teil des Lagerschenkels 5 des Verriegelungshebels 3 in Schließstellung eine Federdruckanlage ermöglicht, die eine sichere Verrasterung des Verschlußschenkels 6 des Verriegelungshebels 3 mit dem Steckteil 12 des Steckverbinders 1 ermöglicht. The invention relates to an electrical connector 1 with at least one on a base part 9 of the connector 1 mounted locking lever 3, the as a one-piece, integral component is designed such that a spring arm 8 pronounced part of the bearing leg 5 of the locking lever 3 in Closed position allows a spring pressure system, which ensures a secure latching the locking leg 6 of the locking lever 3 with the male part 12 of the Connector 1 allows.
