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 is finally a connector with a locking lever known in which the locking lever with the help of two Bearing arms are rotatably mounted on a bearing journal. The bearing arms are after Cut type of rag from a plate forming the locking lever. In addition to these two bearing arms is the locking lever forming plate cut out a locking spring acting as a leaf spring.

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 each other 3, which are interconnected by a transverse yoke 4. The locking lever 3 is a one-piece, integral member that is preferred is plate-shaped. It comprises a bearing leg 5 and one 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 tab-shaped, Bearing arms 7, 8 forms. The bearing arms 7, 8 can for example by slitting the bearing leg 5 or by cutting free or a otherwise working out a bearing arm or both bearing arms from the Bearing legs 5 are formed. For forming the bearing arm or arms the bearing leg can be, for example, cutting, milling or punching processes be considered. In the event that only one bearing arm 8 is cut free, part of the bearing arm 5 serves as a second bearing arm 7. The from the bearing arm 5 trained bearing arms 7, 8 lie essentially 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 swivel for mounting 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, the bearing arms 7, 8 embrace the bearing pin 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, the bearing arms 7, 8 lie closely against the bearing journal 10 and enable them a firm hold of the locking lever 3 on the journal 10. Die Bearing arms 7, 8 are hollowed out for receiving the bearing journal 10. The The radius of the troughs 11 preferably corresponds 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, a plug 12 is in the plugging direction 13 placed on the base part 9, with a between the two parts resilient seal (not shown). Then the on the Base part 9 stored locking lever 3 locked with the plug part 12. At the Closing the snap lock is the locking lever 3 in one plane pivots about 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 closure leg 6 is designed such that he a locking pin 14 when closing the snap lock Engages behind the plug part of the connector. The locking lever shown on the right in Fig. 3 3 illustrates a point in time during the locking leg locking 6, in which the lock is almost closed. One recognises the crossing of the locking leg 6 on the locking pin 14 on Plug 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 a spring arm 8 educated. The spring arm 8 is designed such that the locking lever 3 for locking and unlocking the locking leg 6 against the spring force of the spring arm 8 relative to the base part 9 in the direction of the plug-in part 12 can be moved. This makes closing and opening very safe the locking enables. The strength of the spring action of the spring arm 8 can through various constructive measures, such as a change the strength of the spring arm foot can be adjusted. By deflecting the Spring arm 8 when moving the locking lever 3 in the direction of Plug part 12 is the encompassing of the bearing pin 10 by the bearing arms 7, 8 changed so that now only the spring arm 8 rests on the bearing pin 10. That of the journal 10 and the bearing arm 7 on the one hand and the spring arm 8 joint formed on the other hand thus acts as a rotary-thrust 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.The locking lever 3 preferably has a further one from the bearing leg 5 trained stop arm 15, which preferably in the same way and How the bearing arms 7, 8 is formed from the bearing leg 5. As in Fig. 3 (right) shown, this is designed so that it has a stop for the Spring arm 8 forms the spring travel when the spring arm 8 is deflected limit. The risk of the spring arm 8 breaking or overstretching this reduces excessive deflection.

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 FIG. 3 shows a completely closed one Locking. The locking leg 6 of the locking lever 3 by reaching behind the locking pin 14 with the plug-in part 12 locked. The principle of the locking lever 3 is based on the fact 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 pressure on the elastic seal (not shown) between base part 9 and plug-in part 12. The locking leg 6 is preferably for reaching behind the locking pin 14 tired out. The radius of the recess 16 corresponds to this 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.Bearing pin 10 and locking pin 14 are in terms of their training and Arrangement on base part 9 and plug part 12 of the connector 1 are identical. Therefore the locking lever 3 can optionally also on the locking pin 14 be storable. In this case, the bearing journal 10 takes on the function of a Locking pin. This makes it possible to use different plug-in parts 12 on one and the same base part 9. Due to the resilient design of the locking lever 3, which allow tolerance compensation, are below Under certain circumstances, base parts and plug-in parts from different manufacturers 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 securely connecting base part 9 and plug part 12 of a connector 1 at least one locking lever 3 is used. By connecting a plurality of locking levers 3 to locking brackets 2 as shown in FIGS. 1-3 the handling is further simplified. Locking lever 3 and Locking bracket 2 can also be combined with other fasteners 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 Characteristics. 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 it 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 secure locking and unlatching.
