Description

Die Erfindung betrifft eine elektrische Steckverbindung mit einem oder zwei um Lagerzapfen der einen Steckverbindungshälfte schwenkbaren, U-förmigen Verriegelungsbügel, wobei bei verriegelter Steckverbindung an dessen Seitenteilen angeordnete Verriegelungselemente / Verriegelungsmittel an der anderen Steckverbindungshälfte angeordnete Verriegelungszapfen übergreifen.The invention relates to an electrical connector with one or two around pivot pin of one connector half, U-shaped Locking bracket, whereby when the connector is locked its side parts arranged locking elements / locking means locking pins arranged on the other half of the connector spread.

Bei derartigen Steckverbindungen ist eine Kniehebelwirkung des Verriegelungsbügels erforderlich, die einen einwandfreien Andruck der beiden Steckverbindungshälften aneinander gewährleistet sowie in bezug auf den Verriegelungsbügel ein relativ leichtes Erreichen der Verschlußstellung mit definierter Endlage ermöglicht.With such plug connections there is a toggle lever effect of the locking bracket required a perfect proof of the two Connector halves guaranteed together and in relation to the Locking bracket with a relatively easy reaching the locking position defined end position.

Aus der DE-C-26 32 338 ist es zur Erfüllung dieser Erfordernisse bekannt, den Verriegelungsbügel aus Blechmaterial U-förmig zu biegen und die Seitenteile mit Übergreifteilen zu versehen, die die Verriegelungszapfen der anderen Steckverbindungshälfte beim Verriegeln übergreifen. Die Lagerung des Verriegelungsbügels erfolgt über Zapfen an der einen Steckverbindungshälfte, die in einer schlitzförmigen Öffnung im Seitenteil geführt und durch ein Federelement gehalten sind.
Dieser im großen und ganzen zufriedenstellende Verriegelungsbügel ist jedoch aufwendig in seiner Herstellung.From DE-C-26 32 338 it is known to meet these requirements to bend the locking bracket made of sheet metal material U-shaped and to provide the side parts with overlapping parts that overlap the locking pin of the other connector half when locking. The locking bracket is mounted on pins on one connector half, which are guided in a slot-shaped opening in the side part and are held by a spring element.
However, this generally satisfactory locking bracket is complex to manufacture.

Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Steckverbindung der eingangs genannten Art dahingehend auszubilden, daß der bzw. die Verriegelungsbügel einfach und kostengünstig herstellbar sind. The invention has for its object an electrical connector of the type mentioned in such a way that the Locking brackets are easy and inexpensive to manufacture.

Diese Aufgabe wird dadurch gelöst, daß in den Seitenteilen sich in Richtung der Seitenteile erstreckende Taschen eingeformt sind, daß in die Taschen jeweils ein Federelement eingefügt ist, dessen unteres Ende vom Lagerzapfen der Steckverbindungshälfte durchdrungen und gehalten ist, und daß das obere Ende des Federelements beim Schließen des Verriegelungsbügels über den jeweiligen Verriegelungszapfen der anderen Steckverbindungshälfte greift und dabei derart auf den Verriegelungszapfen einwirkt, daß die beiden Steckvorrichtungshälften federnd gegeneinandergepreßt sind. Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 6 näher erläutert.This object is achieved in that in the side parts in the direction of the side panels extending pockets are molded that into the pockets a spring element is inserted, the lower end of the bearing pin the connector half is penetrated and held, and that upper end of the spring element when closing the locking bracket over the respective locking pin of the other connector half engages and acts in such a way on the locking pin that the two Plug device halves are resiliently pressed against each other. Advantageous embodiments of the invention are in claims 2 to 6 explained in more detail.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Verriegelungsbügel kostengünstig aus Kunststoffmaterial durch Spritzgießen hergestellt werden können und daß die zur Erzeugung der Verriegelungskräfte vorgesehenen Federelemente einfach in die Taschen in den Seitenteilen eingelegt werden und beim Aufschnappen des Verriegelungsbügels auf die entsprechenden Lagerzapfen am Gehäuse gehalten sind. Besonders niedrige Betätigungskräfte, bei dennoch hohen Zuhaltekräften ergeben sich bei Verwendung von Federelementen mit an diesen vorgesehenen Kipphebelelementen, die beim Aufgleiten auf die Verriegelungszapfen nach Überschreiten eines oberen Totpunkts in die Verriegelungsstellung schwenken/kippen.The advantages achieved by the invention are in particular that the locking bracket inexpensively from plastic material by injection molding can be produced and that to generate the locking forces provided spring elements simply in the pockets in the Side panels are inserted and when the locking bracket is snapped on are held on the corresponding journal on the housing. Particularly low actuation forces with high locking forces arise when using spring elements provided on these Rocker arm elements that slide onto the locking pin after passing an upper dead center into the locking position swivel / tilt.

In der Fig. 1 ist eine elektrische Steckverbindung dargestellt, wobei zwei Steckverbindungshälften 1, 2 miteinander gekuppelt sind. Die Steckverbindungshälften sind mit hier nicht näher dargestellten elektrischen Kontaktelementen versehen, die beim Zusammenfügen der Steckverbindungshälften miteinander in Kontakt gelangen. Zur Verriegelung der Steckverbindungshälften sind U-förmige Verriegelungsbügel 3 vorgesehen, die auf Lagerzapfen 4 der einen Steckverbindungshälfte 2 schwenkbar gehalten sind. Die Verriegelungsbügel, die als Einzelteil in der Fig. 2 dargestellt sind, weisen ein Griffteil 5 auf, von dem sich rechtwinklig Seitenteile 6 weg erstrekken. Im unteren Bereich der Seitenteile ist jeweils eine Lageröffnung 7 vorgesehen, durch die sich nach der Montage des Verriegelungsbügels an der Steckverbindungshälfte 2 der jeweilige Lagerzapfen 4 erstreckt. Die Verriegelungsbügel sind vorzugsweise aus Kunststoffmaterial hergestellt. In die Seitenteile 6 sind schmale Taschen 8 eingeformt, die sich in Richtung der Seitenteile erstrecken und die nach vorn hin offen sind. In diese Taschen sind die in der Fig. 3 dargestellten Federelemente 9 eingelegt, wobei ein Ansatz 10 der Federelemente in eine Halterungsausnehmung 11 der Tasche eingeschoben ist. Die Federelemente sind zur Erzielung guter Federeigenschaften vorzugsweise aus metallischem Werkstoff hergestellt.
Im unteren Bereich der Federelemente ist eine ösenartige Anformung mit einer Durchgangsöffnung 12 vorgesehen, die nach dem Einfügen des Federelements mit der Lageröffnung 7 der Seitenteile fluchtet.
Im oberen Bereich des etwa halbrund geformten Federelements ist eine Öffnung 13 eingeformt, in die das in der Fig. 3 dargestellte Verriegelungselement 14 eingesetzt ist. Dabei weist das Verriegelungselement eine entsprechend dieser Öffnung geformte, etwa runde Anformung 15 auf, so daß dieses schwenkbar an dem Federelement gehalten ist. Die Form der Öffnung 13 und der Anformung 15 sind so aufeinander abgestimmt, daß die Anformung von der Seite her in die Öffnung einfügbar ist und dabei nach unten hin nicht herausrutschen kann. Das Verriegelungselement ist mit einer kurvenförmigen Kontur 16 versehen, die beim Verriegeln der Steckverbindungshälften auf die Verriegelungszapfen 17 der Steckverbindungshälfte 1 aufgleitet und wobei in der Endstellung des Verriegelungsbügels die Verriegelungszapfen 17 in der Rundung 18 anliegen.
Die Wirkungsweise der Verriegelung wird nachfolgend an Hand der Fig. 1 erläutert. In der Fig. 1 sind zum besseren Erkennen der Wirkungsweise die Verriegelungsbügel in unterschiedlichen Stellungen dargestellt, und die Taschen der Seitenteile sind mit weggebrochener Vorderwand gezeichnet.
Der linke Verriegelungsbügel ist dabei in einer Stellung gezeigt, in der das Verriegelungselement 14 auf den Verriegelungszapfen 17 auftrifft bzw. aufgleitet. Beim weiteren Schließen des Verriegelungsbügels wird das Federelement 9 aufgebogen, das Verriegelungselement gleitet mit seiner Kontur 16 auf dem Verriegelungszapfen entlang und gelangt schließlich nach Überschreiten eines oberen Totpunkts in die Endstellung, die beim rechten Verriegelungsbügel gezeigt ist. Bei dieser Bewegung in die Endstellung des Verriegelungsbügels schwenkt das Verriegelungselement, und der Verriegelungszapfen 17 liegt schließlich in der Rundung 18.
Durch entsprechende Form der Kontur 16 und Anlage des oberen Bereichs 19 an einer Kante 20 des Federelements ist gewährleistet, daß das Verriegelungselement in dieser Stellung verharrt. Das Verriegelungselement ist dabei von der Wirkung her als Kipphebelelement ausgebildet. In der verriegelten Stellung wirkt die Federkraft der Federelemente derart, daß die Steckverbindungshälften fest zusammengepreßt werden.In Fig. 1, an electrical connector is shown, wherein two connector halves 1, 2 are coupled together. The connector halves are provided with electrical contact elements, not shown here, which come into contact with one another when the connector halves are joined together. To lock the connector halves, U-shaped locking brackets 3 are provided, which are pivotally held on bearing pins 4 of the one connector half 2. The locking brackets, which are shown as an individual part in FIG. 2, have a grip part 5, from which side parts 6 extend at right angles. A bearing opening 7 is provided in the lower region of the side parts, through which the respective bearing pin 4 extends after the locking bracket has been mounted on the connector half 2. The locking bracket is preferably made of plastic material. Narrow pockets 8 are formed in the side parts 6, which extend in the direction of the side parts and which are open towards the front. The spring elements 9 shown in FIG. 3 are inserted into these pockets, an extension 10 of the spring elements being inserted into a holder recess 11 of the pocket. The spring elements are preferably made of metallic material to achieve good spring properties.
In the lower area of the spring elements, an eyelet-like formation is provided with a through opening 12 which is aligned with the bearing opening 7 of the side parts after the spring element has been inserted.
In the upper area of the approximately semicircular spring element, an opening 13 is formed, into which the locking element 14 shown in FIG. 3 is inserted. In this case, the locking element has an approximately round projection 15 shaped in accordance with this opening, so that it is pivotably held on the spring element. The shape of the opening 13 and the molding 15 are coordinated with one another in such a way that the molding can be inserted into the opening from the side and cannot slide out downwards. The locking element is provided with a curved contour 16 which slides onto the locking pin 17 of the connector half 1 when the connector halves are locked and, in the end position of the locking bracket, the locking pins 17 rest in the rounding 18.
The operation of the lock is explained below with reference to FIG. 1. In Fig. 1, the locking bracket is shown in different positions for better recognition of the mode of action, and the pockets of the side parts are drawn with the front wall broken away.
The left locking bracket is shown in a position in which the locking element 14 strikes or slides on the locking pin 17. When the locking bracket is closed further, the spring element 9 is bent open, the locking element slides with its contour 16 along the locking pin and finally, after it has passed an upper dead center, reaches the end position shown in the right locking bracket. During this movement into the end position of the locking bracket, the locking element pivots, and the locking pin 17 finally lies in the curve 18.
A corresponding shape of the contour 16 and the contact of the upper region 19 on an edge 20 of the spring element ensures that the locking element remains in this position. The locking element is in effect designed as a rocker arm element. In the locked position, the spring force of the spring elements acts such that the connector halves are pressed together firmly.

In der Fig. 5 ist eine elektrische Steckverbindung mit modifizierten Verriegelungsbügeln 3' dargestellt, wobei auch hier U-förmige Verriegelungsbügel vorgesehen sind, die auf Lagerzapfen 4 der Steckverbindungshälfte 2 schwenkbar gehalten sind.

Weiterhin weisen diese Verriegelungselemente Lager- bzw. Halterungszapfen 22 auf.
Die Verriegelungselemente sind im oberen Bereich der Seitenteile des Verriegelungsbügels in die Taschen eingeschoben, wobei sie über die Lagerzapfen, die in Langlöcher 23 eingeclipst sind, schwenkbar gehalten sind. Das obere Ende 21 der Federelemente drückt dabei zunächst federnd auf die Fläche 24 der Verriegelungselemente.In contrast to the spring element 9 described further above, this spring element 9 'is also of approximately semicircular design, but the upper end 21 is designed to end smoothly.
Locking elements 14 'shown in FIG. 8 are provided for the locking bracket. These are approximately triangular-shaped with a curved contour 16 ', which slides onto the locking pins 17 of the connector half 1 when the connector halves are locked and, in the end position of the locking bracket, the locking pins 17 rest in the curve 18. Furthermore, these locking elements have bearing or mounting pins 22.

The upper end 21 of the spring elements first presses resiliently on the surface 24 of the locking elements.

Die Wirkungsweise der Verriegelung wird nachfolgend an Hand der Fig. 5 erläutert. In der Fig. 5 sind zum besseren Erkennen der Wirkungsweise die Verriegelungsbügel in unterschiedlichen Stellungen dargestellt, und die Taschen der Seitenteile sind mit weggebrochener Vorderwand gezeichnet. Der linke Verriegelungsbügel ist dabei in einer Stellung gezeigt, in der das Verriegelungselement 14' auf den Verriegelungszapfen 17 auftrifft bzw. aufgleitet. Beim weiteren Schließen des Verriegelungsbügels gleitet das Verriegelungselement 9' mit seiner Kontur 16' auf dem Verriegelungszapfen entlang und kippt schließlich nach Überschreiten eines oberen Totpunkts in die Endstellung, die beim rechten Verriegelungsbügel gezeigt ist. Dabei liegt dann die Fläche 25 am oberen Ende des Federelements an bzw. das Federelement drückt auf das Verriegelungselement, und der Verriegelungszapfen 17 liegt in der Rundung 18. Durch die Führung bzw. Halterung des Verriegelungselements in den Langlöchern 23 ist gewährleistet, daß der Federdruck der Federelemente über die Verriegelungselemente auf die Verriegelungszapfen wirkt und die Steckverbindungshälften fest zusammengepreßt werden.The mode of operation of the locking is described below with reference to FIG. 5 explained. 5 are for better recognition of the mode of operation Locking bracket shown in different positions, and the pockets the side parts are drawn with the front wall broken away.

In the lower area of the spring elements, an eyelet-like formation is provided with a through opening 12 which is aligned with the bearing opening 7 of the side parts after the spring element has been inserted.

Im Gegensatz zu den vorstehend beschriebenen Federelementen ist dieses Federelement 9" zwar auch etwa halbrund ausgebildet, das obere Ende ist jedoch mit einer rundlichen Anformung 26 versehen. Es kann vorgesehen sein, daß das Federelement, wie vorstehend bereits erläutert, in die Taschen der Verriegelungsbügel eingesetzt wird und wobei beim Schließen der Verriegelungsbügel die Anformung direkt über den jeweiligen Verriegelungszapfen gleitet und nach Überschreiten eines oberen Totpunkts die Steckverbindungshälften durch die Federkraft des Federelements fest zusammengepreßt werden.
Vorzugsweise ist jedoch zur Verminderung von Reibungswiderständen, d. h. zum leichteren Schließen der Verriegelungsbügel vorgesehen, das obere Ende mit einer Öffnung 27 zu versehen und darin die in der Fig. 12 dargestellte Rolle 28 aufzunehmen. In contrast to the spring elements described above, this spring element 9 ″ is also approximately semicircular, but the upper end is provided with a rounded shape 26. It can be provided that the spring element, as already explained above, is inserted into the pockets of the locking bracket is and when the locking bracket closes, the molding slides directly over the respective locking pin and, after exceeding an upper dead center, the connector halves are pressed together firmly by the spring force of the spring element.
However, in order to reduce frictional resistance, that is to say to make it easier to close the locking bracket, the upper end is preferably provided with an opening 27 and the roller 28 shown in FIG.

Die Wirkungsweise dieser Verriegelung wird nachfolgend an Hand der Fig. 9 erläutert. In der Fig. 9 sind zum besseren Erkennen der Wirkungsweise die Verriegelungsbügel in unterschiedlichen Stellungen dargestellt, und die Taschen der Seitenteile sind mit weggebrochener Vorderwand gezeichnet.
Der linke Verriegelungsbügel ist dabei in einer Stellung gezeigt, in der die Rolle 28 auf den Verriegelungszapfen 17 auftrifft bzw. aufgleitet. Beim weiteren Schließen des Verriegelungsbügels gleitet/rollt die Rolle über den Verriegelungszapfen und gelangt schließlich nach Überschreiten eines oberen Totpunkts in die Endstellung, die beim rechten Verriegelungsbügel gezeigt ist. Der Federdruck der Federelemente wirkt jetzt auf die Verriegelungszapfen, und die Steckverbindungshälften werden fest zusammengepreßt.The operation of this lock is explained below with reference to FIG. 9. In Fig. 9, the locking bracket is shown in different positions for better recognition of the mode of action, and the pockets of the side parts are drawn with the front wall broken away.
The left locking bracket is shown in a position in which the roller 28 strikes or slides on the locking pin 17. When the locking bracket is closed further, the roller slides / rolls over the locking pin and finally reaches the end position shown on the right locking bracket after it has passed an upper dead center. The spring pressure of the spring elements now acts on the locking pins, and the connector halves are pressed together firmly.
