Abstract

PCT No. PCT/EP88/00186 Sec. 371 Date Nov. 28, 1988 Sec. 102(e) Date Nov. 28, 1988 PCT Filed Mar. 10, 1988 PCT Pub. No. WO88/08212 PCT Pub. Date Oct. 20, 1988.In an electrical coupling device with one contact strip firmly secured, for example, to the frame of the unit, and with one socket strip lodged in a housing, and with means for preventing incorrect coupling, in order to achieve easy and safe connection, the socket strip housing is fitted to the frame by a pivot pin arranged at one end of the housing and has a slide groove in at least one lateral longitudinal wall. By displacing in the slide groove a sliding block carried by means of a lever hinged to the frame, the socket strip housing can be pivoted and locked in order to permit coupling of the strip contacts and socket contacts to the contact strip.

Description

Die Erfindung betrifft eine elektrische Kupplungsvorrichtung mit einer, z. B. an einem Geräterahmen fest angeordneten Messerleiste und einer in einem Gehäuse untergebrachten Buchsenleiste sowie Mitteln zum Verhindern eines falschen Kuppelns.The invention relates to an electrical coupling device with a, for. B. on a device frame fixedly arranged male connector and a female connector housed in a housing and means for preventing false coupling.

Bei vielpoligen elektrischen Kupplungsvorrichtungen erfordern die Steckvorgänge der Messerstifte und Buchsenkörper eine exakt ausgerichtete Zuordnung derselben zueinander sowie einen relativ großen Kraftaufwand. Außerdem ist bei ungenügend weiter Steckung, die Beibehaltung der Stekkung nicht sicher gewährleistet.In the case of multi-pole electrical coupling devices, the plugging operations of the knife pins and socket bodies require an exactly aligned assignment of the same to one another and a relatively large expenditure of force. In addition, if the plug is insufficiently wide, maintaining the plug is not guaranteed.

Es ist Aufgabe der Erfindung, den Steckvorgang und die Beibehaltung der Steckung bei elektrischen Kuppelvorrichtungen der vorgenannten Art zu erleichtern und sicherer zu machen.It is an object of the invention to facilitate the plugging process and the maintenance of the plug in electrical coupling devices of the aforementioned type and to make them safer.

Erfindungsgemäß ist hierzu das Buchsenleistengehäuse mittels an einem Ende desselben angeordnete Gelenkzapfen am Geräterahmen anhängbar, weist in mindestens einer Seitenlängswand eine Kulissennut auf und es ist durch Verschieben eines durch einen am Geräterahmen angelenkten Hebels getragenen Kulissensteins in der Kulissennut das Buchsenleistengehäuse zur Kupplung von Messerleisten- und Buchsenleistenkontakten an die Messerleiste anschwenk- und arretierbar. Nach bevorzugter Ausführung ist das Buchsenleistengehäuse in beiden Seitenlängswänden mit einer Kulissennut identischer Kurvenführung versehen und in beiden Kulissennuten sind jeweils ein durch einen Hebel getragene Kulissensteine gleichzeitig synchron führbar. Zweckmäßig sind die Hebel als Doppelhebel mit verschieden langen Hebelarmen ausgebildet, deren kurze Hebelarme die Kulissensteine tragen. Außerdem sind zum Zwecke einer gleichzeitigen, gleichmäßigen Betätigung beider Doppelhebel die freien Enden der langen Hebelarme beider Hebel durch einen Steg miteinander fest verbunden. Die Steckvorgänge von Messer- und Buchsenleisten können nunmehr durch eine einfache Anschwenkung des mittels des Gelenkzapfens am Geräterahmen angehängten Buchsenleistengehäuses und einer Verschwenkung der Hebel bewirkt werden, wobei der erforderliche Kraftaufwand den Hebelarmverhältnissen entsprechend gering ist. Eine Arretierung wird durch einen Überhub für die Hebel erzielt, deren Handhabung durch den Steg erleichtert ist. Darüberhinaus ist vorgesehen, die Hebel sowohl in der Haltestellung für das Buchsenleistengehäuse als auch in der Freigabestellung für dieses lösbar, verrastbar am Geräterahmen und/oder Buchsenleistengehäuse auszubilden. Zur Verrastung können Nocken oder Anformungen am Geräterahmen oder am Buchsenleistengehäuse dienen, die in den Bewegungsweg der Hebel einragen und durch Überlaufen die Hebel arretieren.According to the invention, for this purpose, the socket strip housing can be attached to the device frame by means of articulated pins arranged at one end thereof, has a link groove in at least one side longitudinal wall, and the socket strip housing for coupling male and female connector contacts is connected to the link groove by moving a link block carried by a lever articulated on the device frame can be swiveled and locked onto the male connector. According to a preferred embodiment, the socket strip housing is provided in both side longitudinal walls with a link groove having identical curve guidance, and in both link slots a link blocks carried by a lever can be guided synchronously at the same time. The levers are expediently designed as double levers with lever arms of different lengths, the short lever arms of which support the sliding blocks. In addition, for the purpose of simultaneous, uniform actuation of both double levers, the free ends of the long lever arms of both levers are firmly connected to one another by a web. The plugging operations of knife and socket strips can now be effected by simply pivoting the socket strip housing attached to the device frame by means of the hinge pin and pivoting the lever, the force required being correspondingly low for the lever arm ratios. A lock is achieved by an overstroke for the levers, the handling of which is facilitated by the web. In addition, provision is made for the levers to be designed to be detachable, latchable on the device frame and / or socket strip housing both in the holding position for the socket strip housing and in the release position for the latter. Cams or projections on the device frame or on the socket strip housing can be used for locking, which protrude into the movement path of the levers and lock the levers by overflowing.

Schließlich sind noch Maßnahmen zur Stekkung vorbestimmter Buchsenleisten an Messerleisten dadurch erreichbar, daß z. B. die Seitenwände des Buchsenleistengehäuses axial hintereinander eine Anzahl Ausnehmungen aufweisen, die mit geräterahmenfesten Kodierstiften zur Wirkung bringbar sind. Die Ausnehmungen sind zweckmäßig zu behinderungsfreien Abschwenkungen des Buchsenleistengehäuses durch Kreisbogenabschnitte begrenzt, deren gemeinsamer Mittelpunkt in den Gelenkzapfen liegt.Finally, measures for plugging predetermined socket strips on male strips can be achieved in that, for. B. the side walls of the female connector housing axially one behind the other have a number of recesses which can be brought into effect with coding pins fixed to the frame. The recesses are expediently restricted to the pivoting of the socket strip housing without hindrance by circular arc sections, the common center of which lies in the pivot pin.

Ferner ist vorgesehen, die Einführung der Kulissensteine in die Kulissennuten dadurch zu erleichtern, daß die Kulissennuten am Einführende einen in Einführrichtung sich konisch verjüngenden Kulissennutenteil aufweisen, an den sich jeweils quer erstreckende Kulissennutenteile anschließen. Der konische Kulissennutenteil läßt eine selbständige Ausrichtung des Buchsenleistengehäuses zu, während die letzterwähnten Kulissennutenteile durch Vorbeiführen der Kulissensteine die Anhebung des Buchsenleistengehäuses in Richtung Geräterahmen ermöglichen. Die exakte Ausrichtung des Buchsenkörpers wird noch dadurch unterstützt, daß der Buchsenkörper auf den Seitenlängswänden bogenförmige Leistenabschnitte fest aufweist, die sich auf den Geräterahmen, insbesondere der Stirnseite desselben abstützen.Furthermore, it is provided to facilitate the introduction of the sliding blocks into the sliding slots in that the sliding slots on the insertion have a sliding slot part which tapers conically in the insertion direction, to which each connecting groove parts extending transversely extend. The conical link groove part allows the socket strip housing to be oriented independently, while the latter slot groove parts enable the socket strip housing to be raised in the direction of the device frame by passing the slide blocks. The exact alignment of the socket body is further supported by the fact that the socket body on the side longitudinal walls has curved strip sections which are supported on the device frame, in particular the end face thereof.

Gemäß einer Weiterbildung der Kupplungsvorrichtung ist vorgesehen, die Doppelhebel und den Steg durch einen einstückigen Formteil und die Gelenkzapfen und/oder die Kulissensteine durch an den Doppelhebeln angeordnete tiefgezogene Ansätze zu bilden. Abgesehen davon, daß die so geschaffene Ausbildung der das Buchsenleistengehäuse verschwenkenden Doppelhebel einfacher wird, führen die einstückigen Ansätze auch zu einer Verfestigung der Doppelhebel. Nach bevorzugter Ausbildung ist zur Vermeidung von unbeabsichtigtem Heraustreten der Gelenkzapfen aus den Zapfenlagern vorgesehen, an den die Gelenkzapfen bildenden Ansätzen je einen abbiegbaren Lappen anzuschneiden, die in an den Zapfenlagern anschließende Ringnuten als axiale Abstützglieder für die Doppelhebel eintauchen.According to a further development of the coupling device, it is provided that the double levers and the web are formed by a one-piece molded part and the pivot pins and / or the sliding blocks by deep-drawn approaches arranged on the double levers. Apart from the fact that the thus created design of the double lever pivoting the socket strip housing becomes simpler, the one-piece approaches also lead to a solidification of the double lever. According to a preferred embodiment, in order to avoid inadvertent stepping out of the pivot pins from the pivot bearings, a bendable flap is to be cut at each of the lugs forming the pivot pins, which tabs are immersed in ring grooves adjoining the pivot bearings as axial support members for the double levers.

Darüberhinaus kann eine axiale Fixierung der Doppelhebel an den Seitenwangen des Geräterahmens auch dadurch erzielbar sein, daß die die Gelenkzapfen bildenden Ansätze je eine Ausdrükkung und die zugeordneten Gelenkzapfenlager zu den Arbeits- und Ruhestellungen der Doppelhebel versetzt je eine sich am Gelenkzapfenlager anschließende Durchführungsöffnung für die Ausdrükkungen der Ansätze aufweisen. Das Einbringen bzw. das Entnehmen der Ansätze aus den Gelenkzapfenlagern ist einfach nach Gegenüberstellung von Ausdrückungen und Durchführungsöffnungen für diese möglich.In addition, an axial fixation of the double levers on the side cheeks of the device frame can also be achieved in that the lugs forming the pivot pins each express and the associated pivot pin bearings for the working and rest positions of the double levers each offset a through-opening for the expressions of the pivot pin bearing Have approaches. The insertion or removal of the lugs from the pivot pin bearings is easy after comparison of expressions and through openings for these possible.

In den Fig. 1 ist mit ein Geräterahmen bezeichnet, der z. B. in einem Kraftfahrzeug angeordnet sein kann. Der Geräterahmen 1 trägt eine vielpolige Messerleiste 2, die mit dem Geräterahmen 1, z. B. durch Gewindeschrauben fest verbunden ist. Mit 3 ist ein Buchsenleistengehäuse bezeichnet, das (Fig. 2) in Ausnehmungen 4 eine Anzahl mit den Messerstiften 2' zu kontaktierende Buchsenkörper 5 aufnimmt. Am Geräterahmen 1 sind im Abstand parallel Seitenwangen 6 angeordnet, die das Buchsenleistengehäuse 3 zwischen sich aufnehmen. An den Seitenwangen 6 sind mittels Zapfen 7 Doppelhebel 8 mit verschieden langen Hebelarmen 8', 8" angelenkt, deren kleinere Hebelarme 8' jeweils einen als Kulissenstein dienenden Zapfen 9 tragen und deren lange Hebelarme 8" am freien Ende durch einen Steg 10 miteinander fest verbunden sind. Die einen einstückigen Formteil bildenden Hebel 8 (Fig. 3) sind aus einer in Fig. 1 strichpunktiert gezeichneten Freigabestellung in die vollgezeichnete Kuppelstellung und umgekehrt abschwenkbar. Mittels Gelenkzapfen 11 ist das Buchsenleistengehäuse 3 an Anformungen 12 des Geräterahmens 1 mit seinem einen Ende anhängbar und verschwenkbar gehalten. In den Seitenlängswänden 3' sind im Buchsenleistengehäuse 3 Kulissennuten 13 ausgebildet, die durch einen konischen Kulissennutenteil 13' und einen quer zu diesem sich erstreckenden Kulissennutenteil 13" mit im wesentlichen parallelen Begrenzungswänden gebildet sind. Außerdem nimmt das Buchsenleistengehäuse 3 kreisbogenabschnittsförmige Ausnehmungen 21 oder Kammern auf, die als Teileinrichtungen eines Kodiersystems der Aufnahme von an den Seitenwangen 6 angeordneten Kodierstiften 14 dienen. Am Buchsenleistengehäuse 3 schließt sich eine Abdeckkappe 15 fest an.In Fig. 1, a device frame is designated, the z. B. can be arranged in a motor vehicle. The device frame 1 carries a multi-pin socket 2, which with the device frame 1, z. B. is firmly connected by threaded screws. 3 denotes a socket strip housing which (FIG. 2) accommodates a number of socket bodies 5 to be contacted with the knife pins 2 'in recesses 4. On the device frame 1, side cheeks 6 are arranged at a distance in parallel and accommodate the socket strip housing 3 between them. On the side walls 6 double levers 8 are articulated by means of pins 7 with lever arms 8 ', 8 "of different lengths, the smaller lever arms 8' of which each carry a pin 9 serving as a sliding block and the long lever arms 8" of which are firmly connected to one another at the free end by a web 10 are. The levers 8 (FIG. 3) forming a one-piece molded part can be pivoted out of a release position shown in broken lines in FIG. 1 into the fully drawn dome position and vice versa. By means of pivot pins 11, the socket strip housing 3 is attached to the formations 12 of the device frame 1 with one end which can be attached and pivoted. In the side longitudinal walls 3 ', 3 slot grooves 13 are formed in the socket strip housing, which are formed by a conical slot groove part 13' and a slot groove part 13 "extending transversely thereto and having essentially parallel boundary walls. In addition, the socket strip housing 3 receives recesses 21 or chambers in the form of circular sections. which serve as sub-devices of a coding system for receiving coding pins 14 arranged on the side walls 6. A cover cap 15 is firmly attached to the socket strip housing 3.

Zur Kupplung von Messer- und Buchsenleisten ist davon auszugehen, daß der Buchsenleistenkörper 3 durch Einhängen der Gelenkzapfen 11 in den Anformungen 12 zunächst die in Fig. 1 strichpunktierte Stellung einnimmt. Die Hebel 8 befinden sich ebenfalls in der strichpunktierten Freigabestellung. Durch Anschwenken des Buchsenleistengehäuses 3 in Uhrzeigerdrehrichtung gelangen die Zapfen 9 der Hebel 8 in die Kulissennuten 13, wobei die konischen Kulissennutenteile 13' zu einer Ausrichtung des Buchsenleistengehäuses 3 beitragen. Durch Abschwenken der Hebel 8 entgegen der Uhrzeigerdrehrichtung gelangen die Zapfen 9 in die Kulissennutenteile 9" und führen zu einer Annäherung des Buchsenleistengehäuses 3 an die Messerleiste 2. Das Buchsenleistengehäuse nimmt dabei die vollgezeichnete Stellung der Fig. 1 ein. In dieser Stellung kommt der Steg 10 in einer Einziehung (16) der Abdeckkappe 15 zu liegen. Gleichzeitig werden die Hebel 8 durch einen Überhub und vermittels an den Begrenzungsflächen des Kulissennutenteils 9' angeordneten Anformungen 17 fixiert. Die Ausrichtung des Buchsenleistengehäuses 3 bei der Anschwenkung desselben an den Geräterahmen 1 wird noch durch am Buchsenleistengehäuse 3 angeordnete bogenförmige Leisten 18 gefördert, die sich an den stirnseitigen Enden 6' der Seitenwangen 6 abstützen. Nach erfolgter Anschwenkung des Buchsenleistengehäuses 3 nehmen die Buchsenkörper 5 zugeordnete Messerstifte 2' auf und durch Anpressen eines an der Messerleiste 2 angeordneten Randstreifens 19 an einen Dichtkörper 22 im Buchsenleistengehäuse 3 ist eine dichte Kupplung erzielt. Durch Auflaufen von Kodierstiften 14 an Begrenzungen der Ausnehmungen 21 und Abstützen der Leisten 18 an den Seitenwangen 6 wird eine stets gleiche Stecklage erzielt, wodurch sich Beschädigungen der Hebel 8 bzw. der Messerstifte 2' und Buchsenkörper 5 vermeiden lassen.For the coupling of male and female connectors, it can be assumed that the female connector body 3 initially assumes the position shown in dash-dotted lines in FIG. 1 by hooking the pivot pins 11 into the projections 12. The levers 8 are also in the dot-dash release position. By pivoting the socket strip housing 3 in the clockwise direction of rotation, the pins 9 of the levers 8 enter the link grooves 13, the conical link groove parts 13 ′ contributing to an alignment of the socket strip housing 3. By pivoting the lever 8 in the counterclockwise direction of rotation, the pins 9 enter the slot groove parts 9 "and lead the socket strip housing 3 to come closer to the male connector 2. The socket strip housing assumes the fully drawn position of FIG. 1. In this position, the web 10 comes to lie in a recess (16) of the cover cap 15. At the same time, the levers 8 are fixed by an overstroke and by means of projections 17 arranged on the boundary surfaces of the link groove part 9 '. The alignment of the socket strip housing 3 when the latter is pivoted onto the device frame 1 is still ensured arcuate strips 18 arranged on the socket strip housing 3 are supported, which are supported on the front ends 6 'of the side cheeks 6. After the socket strip housing 3 has been pivoted in, the socket bodies 5 take up knife pins 2' assigned to them and by pressing an edge strip 19 arranged on the knife strip 2 onto egg NEN sealing body 22 in the socket strip housing 3, a tight coupling is achieved. By running coding pins 14 on the boundaries of the recesses 21 and supporting the strips 18 on the side walls 6, the plug position is always the same, whereby damage to the levers 8 or the knife pins 2 'and the socket body 5 can be avoided.

Bei Zurückschwenken der Hebel 8 bewegen sich die Zapfen 9 zur Freigabe des Buchsenleistengehäuses 3 aus den Kulissennuten 13 heraus, wodurch das Buchsenleistengehäuse 3 von der Messerleiste 2 abziehbar und vom Geräterahmen 1 abnehmbar ist. An den Seitenwangen 6 angeordnete Anformungen 20 dienen der Fixierung der Hebel 8 in der Freigabestellung für das Buchsenleistengehäuse 3.When the lever 8 is pivoted back, the pins 9 move out of the link grooves 13 to release the socket strip housing 3, as a result of which the socket strip housing 3 can be removed from the male connector 2 and removed from the device frame 1. Formations 20 arranged on the side cheeks 6 serve to fix the levers 8 in the release position for the socket strip housing 3.

In Fig. 4 sind an den Seitenwangen 6 des Geräterahmens 1 mittels Gelenkzapfen 7 Doppelhebel 8 mit verschieden langen Hebelarmen 8', 8" angelenkt, deren Hebelarme 8' jeweils wiederum einen Kulissenstein 9 tragen und deren Hebelarme 8" am freien Ende durch einen Steg 10 miteinander fest verbunden sind. Die so einen einstückigen Formteil bildenden Hebel 8 (Fig. 5) sind aus einer in Fig.4 strichpunktiert gezeichneten Freigabestellung für das Buchsenleistengehäuse 3 in die vollgezeichnete Kupplungsstellung von Messerstiften der Messerleiste und Buchsenkörper des Buchsengehäuses 3 und umgekehrt abschwenkbar. Mittels Gelenkzapfen 11 ist das Buchsenleistengehäuse 3 an Anformungen 12 des Geräterahmens 1 mit seinem einen Ende anhängbar und verschwenkbar gehalten. In den Seitenlängswänden sind im Buchsenleistengehäuse 3 Kulissennuten 13 ausgebildet, die die Kulissensteine 9 zu Verschwenkungen des Buchsenleistengehäuses 3 aufnehmen.4, double levers 8 with lever arms 8 ', 8 "of different lengths are articulated on the side walls 6 of the device frame 1 by means of pivot pins 7, the lever arms 8' of which in turn each carry a sliding block 9 and their lever arms 8" at the free end through a web 10 are firmly connected. The levers 8 (FIG. 5) thus forming a one-piece molded part can be pivoted out of a release position for the socket strip housing 3 shown in dash-dotted lines in FIG. 4 into the fully drawn coupling position of knife pins of the socket strip and socket body of the socket housing 3 and vice versa. By means of pivot pins 11, the socket strip housing 3 is attached to the formations 12 of the device frame 1 with one end which can be attached and pivoted. In the side longitudinal walls 3 link grooves 13 are formed in the socket strip housing, which accommodate the sliding blocks 9 to pivot the socket strip housing 3.

Beim Ausführungsbeispiel der Fig. 4 - 10 sind die Kulissensteine 9 und die Gelenkzapfen 7 durch tiefgezogene Ansätze (Fig. 5) gebildet und damit einstückig mit den Hebelarmen 8 ausgeführt.In the exemplary embodiment in FIGS. 4 to 10, the sliding blocks 9 and the pivot pins 7 are formed by deep-drawn approaches (FIG. 5) and are therefore made in one piece with the lever arms 8.

In den Fig. 7 und 8 sind an den Gelenkzapfen 7 je ein Lappen 25 angeschnitten, die durch Zurückbiegen ein unbeabsichtigtes Herausgleiten der Gelenkzapfen 7 aus den Gelenkzapfenlager 23 verhindern. Bevorzugt tauchen zur Vermeidung von über die Seitenwangen 6 überstehenden Abschnittten der Gelenkzapfen 7, die Lappen 25 in Ringnuten 26 mit Spiel ein und kommen mit den inneren Begrenzungsflächen 27 der Ringnuten 26 zur Anlage.7 and 8, a flap 25 is cut onto each of the pivot pins 7, which prevent the pivot pins 7 from inadvertently sliding out of the pivot pin bearing 23 by bending back. To avoid portions of the pivot pin 7 projecting beyond the side walls 6, the tabs 25 preferably dip into the annular grooves 26 with play and come into contact with the inner boundary surfaces 27 of the annular grooves 26.

Beim Ausführungsbeispiel der Fig. 9 und 10 tragen die Gelenkzapfen 7 im Bereich der Umfangsfläche je einen Ansatz oder eine Ausdrückung 28, die über von der Freigabestellung und der Arbeitsstellung des Buchsenleistengehäuses versetzten Durchführungsöffnungen 29 in hinterschnittene Ringnuten 30 eintauchen und ein freies Schwenken der Droppelhebel 8 erlauben. Vermittels der Ansätze 28 und der Ringnuten 30 sind die Gelenkzapfen 7 mit Spiel an den Seitenwangen axial fixiert, wodurch ein unbeabsichtigtes Herausgleiten der Gelenkzapfen 7 aus den Gelenkzapfenlagern 23 verhindert ist.In the exemplary embodiment of FIGS. 9 and 10, the pivot pins 7 each have an extension or an expression 28 in the area of the circumferential surface, which plunge into undercut ring grooves 30 via feedthrough openings 29 offset from the release position and the working position of the socket strip housing and allow the dowel levers 8 to pivot freely . By means of the lugs 28 and the annular grooves 30, the pivot pins 7 are axially fixed with play on the side cheeks, thereby preventing the pivot pins 7 from inadvertently sliding out of the pivot pin bearings 23.
