Elektrische KupplungsvorrichtungElectrical coupling device
Die Erfindung betrifft eine elektrische Kupplungsvor¬ richtung mit einer, z. B. an einem Geräterahmen fest angeordneten Messerleiste und einer in einem Gehäuse untergebrachten Buchsenleiste sowie Mitteln zum Verhin¬ dern eines falschen Kuppeins.The invention relates to an electrical coupling device with a z. B. on a device frame fixedly arranged male connector and a female connector housed in a housing and means for preventing a wrong coupling.
Bei vielpoligen elektrischen KupplungsVorrichtungen er- fordern die Steckvorgänge der Messerstifte undIn the case of multi-pole electrical coupling devices, the pushing operations of the knife pins and require
Buchsenkörper eine exakt ausgerichtete Zuordnung der¬ selben zueinander sowie einen relativ großen Kraftauf¬ wand. Außerdem ist bei ungenügend weiter Steckung, die Beibehaltung der Steckung nicht sicher gewährleistet.Socket body an exactly aligned assignment of the same to each other and a relatively large effort. 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 KuppelVor¬ richtungen der vorgenannten Art zu erleichtern und si¬ cherer zu machen.It is an object of the invention to facilitate the plugging process and the maintenance of the plugging in electrical coupling devices of the aforementioned type and to make them safer.
Erfindungsgemäß ist hierzu das Buchsenleistengehäuse mittels an einem Ende desselben angeordnete Gelenkzap¬ fen am Geräterahmen anhängbar, weist in mindestens einer Seitenlängswand eine Kulissennut auf und es ist durch Verschieben eines durch einen am Geräterahmen angelenk¬ ten Hebels getragenen Kulissensteins in der Kulissennut das Buchsenleistengehäuse zur Kupplung von Messer¬ leisten- und Buchsenleistenkontakten an die Messerlei¬ ste anschwenk-; und arretierbar. Nach bevorzugter Aus¬ führung ist das Buchsenleistengehäuse in beiden Seiten- längswänden mit einer Kulissennut identischer Kurven¬ führung versehen und in beiden Kulissennuten sind je¬ weils ein durch einen Hebel getragene Kulissensteine gleichzeitig synchron führbar. Zweckmäßig sind die He¬ bel 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 könneiT unmehr durch eine ein¬ fache Anschwenkung des mittels des Gelenkzapfens am Ge¬ räterahmen angehängten Buchsenleistengehäuses und einer Verschwenkung der Hebel bewirkt werden, wobei der er¬ forderliche Kraftaufwand den Hebelarmverhältnissen ent- s'prechend 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 Buchsen¬ leistengehäuse als auch in der Freigabestellung für die- ses lösbar, verrastbar am Geräterahmen und/oder Buch¬ senleistengehäuse auszubilden. Zur Verrastung können Nocken oder Anformungen am _Geräterahmen oder am Buch¬ senleistengehäuse dienen, die in den Bewegungsweg der Hebel einragen und durch Überlaufen die Hebel arretie- ren. Schließlich sind noch Maßnahmen zur Steckung vor¬ bestimmter Buchsenleisten an Messerleisten dadurch er¬ reichbar, daß z. B. die Seitenwände des Buchsenleisten¬ gehäuses axial hintereinander eine Anzahl Ausnehmungen aufweisen, die mit geräterahmenfesten Kodierstiften zur Wirkung bringbar sind. Die Ausnehmungen sind zweckmäßig zu behinderungsfreien Abschwenkungen des Buchsenleisten¬ gehäuses durch Kreisbogenabschnitte begrenzt, deren ge¬ meinsamer Mittelpunkt in den Gelenkzapfen liegt.For this purpose, according to the invention, 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 it can be moved in the link groove by sliding a link block carried by a lever articulated on the device frame pivot the socket strip housing for coupling knife strips and socket strip contacts to the knife strip; and lockable. According to a preferred embodiment, the socket strip housing is provided in both side longitudinal walls with a link groove of identical curve guidance and in both link grooves 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. S is prechend low, the plug-in operations of male and female connectors könneiT unmehr the lever caused by a ein¬ times Anschwenkung the councils frame by means of the pivot pin at the Ge appended socket strip housing and pivoting, wherein the er¬ ford variable force corresponds to Hebelarmverhältnissen '. A lock is achieved by an overstroke for the levers, whose ' handling is facilitated by the web. In addition, it is provided that the levers are designed to be detachable, lockable 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 path of movement of the levers and lock the levers by overflowing. Finally, measures for connecting certain socket strips to male connectors can also be achieved in that, for. B. the side walls of the socket strip housing have axially one behind the other a number of recesses which can be brought into effect with coding pins fixed to the frame. The recesses are expediently delimited by the circular arc sections, the common center of which lies in the hinge pin, for the pivoting of the socket strip housing without hindrance.
Ferner ist vorgesehen, die Einführung der Kulissensteine in die Kulissennuten dadurch zu erleichtern, daß die Ku¬ lissennuten 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 Buch- senleistengehäuses in Richtung Geräterahmen ermöglichen. Die exakte Ausrichtung des Buchsenkörpers wird noch da¬ durch unterstützt, daß der Buchsenkörper auf den Seiten- längswänden bogenförmige Leistenabschnitte fest auf¬ weist, die sich auf den Geräterahmen, insbesondere der Stirnseite desselben abstützen.Provision is also made to facilitate the insertion of the sliding blocks into the sliding grooves in that the sliding grooves on the insertion have a sliding groove part which tapers conically in the insertion direction and to which the sliding groove parts which extend transversely follow. The conical link groove part allows the socket strip housing to be aligned 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 has curved strip sections on the side longitudinal walls, which are supported on the device frame, in particular on the end face thereof.
Gemäß einer Weiterbildung der Kupplungsvorrichtung ist vorgesehen, die Doppelhebel und den Steg durch einen ein¬ stückigen Formteil und die Gelenkzapfen und/oder die-Ku- lissensteine durch an den Doppelhebeln angeordnete tief¬ gezogene 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 Dop¬ pelhebel. Nach bevorzugter Ausbildung ist zur Vermeidung von unbeabsichtigtem Heraustreten der Gelenkzapfen aus den Zapfenlagern vorgesehen, an den die Gelenkzapfen bil¬ denden Ansätzen je einen abbiegbaren Lappen anzuschnei¬ den, die in an den Zapfenlagern anschließende Ringnuten als axiale Abstützglieder für die Doppelhebel eintauchen.According to a 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 articulated pins and / or the sliding blocks by deep-drawn approaches arranged on the double levers. Aside from the fact that created design of the double lever pivoting the socket strip housing becomes easier, the one-piece approaches also lead to a solidification of the double lever. According to a preferred embodiment, in order to avoid inadvertent emergence of the pivot pins from the pivot bearings, a bendable tab is provided on each of the approaches forming the pivot pins, which lugs enter into ring grooves adjoining the pivot bearings as axial support members for the double levers.
Darüberhinaus kann eine axiale Fixierung der Doppelhebel an den Seiitenwangen des Geräterahmens auch dadurch er¬ zielbar sein, daß die die Gelenkzapfen bildenden Ansätze je eine Ausdrückung und die zugeordnetenGelenkzapfenlager zu den Arbeits- und Ruhestellungen der Doppelhebel ver¬ setzt je eine sich am Gelenkzapfenlager anschließende Durchführungsöffnung für die Ausdrückungen der Ansätze aufweisen. Das Einbringen bzw. das Entnehmen der Ansätze aus den Gelenkzapfenlagern ist einfach nach Gegenüber- Stellung 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 press out and the associated pivot pin bearings for the working and rest positions of the double levers each place a through opening adjoining the pivot pin bearing for which have expressions of approaches. The insertion or removal of the lugs from the pivot pin bearings is possible simply by juxtaposing expressions and through openings for them.

In den Fig. ist mit 1 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 Gewindeschrau¬ ben fest verbunden ist. Mit 3 ist ein Buchsenleisten- gehäuse 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' 1 angelenkt, deren kleinere Hebelarme 8' jeweils einen als Kulissenstein dienenden Zapfen 9 tragen und deren lange Hebelarme 81 ' am freien Ende durch einen Steg 10 miteinander fest ver- bunden sind. Die einen einstückigen Formteil bildendenIn the figures, 1 denotes a device frame which, for. 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 designates a socket strip housing which (FIG. 2) accommodates in recesses 4 a number of socket bodies 5 to be contacted with the knife pins 2 '. 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' 1 of different lengths, the smaller lever arms 8 'of which each carry a pin 9 serving as a sliding block and whose long lever arms 8 1 ' are connected to one another at the free end by a web 10 are firmly connected. The one-piece molding
Hebel 8 (Fig. 3) sind aus einer in Fig. 1 strichpunktiert gezeichneten Freigabestellung in die vollgezeichnete Kuppelstellung und umgekehrt abschwenkbar. Mittels Ge¬ lenkzapfen 11 ist das Buchsenleistengehäuse 3 an An- formungen 12 des Geräterahmens 1 mit seinem einen Ende anhängbar und verschwenkbar gehalten. In den Seiten- längswänden 3 ' sind im Buchsenleistengehäuse 3 Kulis¬ sennuten 13 ausgebildet, die durch einen konischen Ku¬ lissennutenteil 13 ' und einen quer zu diesem sich er¬ streckenden Kulissennutenteil 13 ' ' mit im wesentlichen parallelen.i:Begrenzungswänden gebildet sind. Außerdem nimmt das Buchsenleistengehäuse 3 kreisbogenabschnitts- förmige Ausnehmungen 21 oder Kammern auf, die als Teil¬ einrichtungen eines Kodiersys.tems. der Aufnahme von an den Seitenwangen 6 angeordneten Kodierstiften 14 dienen. Am Buchsenleistengehäuse 3 schließt sich eine Abdeck¬ kappe 15 fest an.Levers 8 (FIG. 3) can be pivoted out of a release position shown in broken lines in FIG. 1 into the fully drawn dome position and vice versa. The socket strip housing 3 is attached to the formations 12 of the device frame 1 with its one end so that it can be attached and pivoted by means of a pivot pin 11. In the side longitudinal walls 3 'are in the socket strip housing 3 Kulis¬ sennuten 13 is formed, the lissennutenteil by a conical Ku¬ 13' and a transversely thereof to er¬ stretching Kulissennutenteil 13 '' with substantially parallelen.i: boundary walls are formed. In addition, the socket strip housing 3 receives arcuate section-shaped recesses 21 or chambers, which are part of a coding system. serve to accommodate 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 Buchsenleάsten ist davon auszugehen, daß der Buchsenleistenkörper 3 durch Ein- hängen der Gelenkzapfen 11 in den Anformungen 12 zu¬ nächst die in Fig. 1 strichpunktierte Stellung einnimmt. Die Hebel 8 befinden sich ebenfalls in der strichpunk¬ tierten Freigabestellung. Durch Anschwenken des Buch¬ senleistengehäuses 3 in Uhrzeigerdrehrichtung gelangen die Zapfen 9 der Hebel 8 in die Kulissennuten 13, wo¬ bei die konischen Kulissennutenteile 13 ' zu einer Aus¬ richtung des Buchsenleistengehäuses 3 beitragen. Durch Abschwenken der Hebel 8 entgegen der Uhrzeigerdrehrich¬ tung gelangen die Zapfen 9 in die Kulissennutenteile 911 und führen zu einer Annäherung des Buchsenleistenge¬ häuses 3 an die Messerleiste 2. Das Buchsenleistengehäu¬ se nimmt dabei die vollgezeichnete Stellung der Fig. 1 ein. In dieser Stellung kommt der Steg 10 in einer Ein- Ziehung (16) der Abdeckkappe 15 zu liegen. Gleichzeitig werden die Hebel 8 durch einen Überhub und vermittels an den Begrenzungsflächen des Kulissennutenteils 9' ange- ordneten Anformungen 17 fixiert. Die Ausrichtung des Buchsenleistengehäuses 3 bei der Anschwenkung desselben an den Geräterahmen 1 wird noch durch am Buchsenleisten¬ gehäuse 3 angeordnete bogenförmige Leisten 18 gefördert, die sich an den stirnseitigen Enden 6' der Seitenwangen 6 abstützen. Nach erfolgter Anschwenkung des Buchsenlei¬ stengehäuses 3 nehmen die Buchsenkörper 5 zugeordnete Messerstifte 2 ' auf und durch Anpressen eines an der Messerledste 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 knife and socket strips, it can be assumed that the socket strip body 3 first 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 dash-dotted release position. By pivoting the socket strip housing 3 in the clockwise direction of rotation, the pins 9 of the levers 8 enter the slot grooves 13, the conical slot groove parts 13 ′ contributing to an alignment of the socket strip housing 3. By pivoting the lever 8 counterclockwise, the pins 9 enter the slot groove parts 9 11 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 an indentation (16) of the cover cap 15. At the same time, the levers 8 are secured by an overstroke and by means of the boundary surfaces of the link groove part 9 '. ordered formations 17 fixed. The alignment of the socket strip housing 3 when it is pivoted onto the device frame 1 is further promoted by curved strips 18 arranged on the socket strip housing 3, which are supported on the front ends 6 'of the side walls 6. After the bushing housing housing 3 has swiveled inwards, the bushing bodies 5 receive associated knife pins 2 'and a tight coupling is achieved by pressing an edge strip 19 arranged on the knife-edge leather 2 against a sealing body 22 in the socket board housing 3. 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 Ku- lissennuten 13 heraus, wodurch das Buchsenleistengehäuse 3 von der Messerleiste 2 abziehbar und vom Geräterahmen 1 abnehmbar ist. An den Seitenwangen 6 angeordnete An¬ formungen 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 slot 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 can be 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 lan- • gen Hebelarmen 81, 8'1 angelenkt, deren Hebelarme 8' je¬ weils wiederum einen Kulissenstein 9 tragen und deren He- beiarme 8'' am freien Ende durch einen Steg 10 miteinan¬ der fest verbunden sind. Die so einen einstückigen Form- teil bildenden Hebel 8 (Fig.5 ) sind aus einer in Fig. 4 strichpunktiert gezeichneten Freigabestellung für das Buchsenleistengehäuse 3 in die vollgezeichne¬ te Kupplungsstellung von Messerstiften' der Messerlei- ste und Buchsenkörper des Buchsengehäuses 3 und umger- kehrt abschwenkbar. Mittels Gelenkzapfen 11 ist das Buchsenleistengehäuse 3 an Anformungen 12 des Geräte¬ rahmens 1 mit seinem einen Ende anhängbar und verschwenk¬ bar gehalten. In den Seitenlängswänden sind im Buchsen- leistengehäuse 3 Kulissennuten 13 ausgebildet, die die Kulissensteine 9 zu Verschwenkungen des Buchsenleisten¬ gehäuses 3 aufnehmen.4, double levers 8 with lever arms 8 1 , 8 ' 1 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 the arm arms 8 thereof '' are firmly connected to each other at the free end by a web 10. So one-piece shape Part-forming levers 8 (FIG. 5) can be swiveled 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 knife 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 slide grooves 13 are formed in the socket strip housing, which receive the sliding blocks 9 for pivoting the socket strip housing 3.
Beim Ausführungsbeispiel der Fig. 4 - 10 sind die Ku- lissensteine 9 und die Gelenkzapfen 7 durch tiefgezoge¬ ne 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 lugs (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 tau¬ chen zur Vermeidung von über die Seitenwangen 6 über¬ stehenden Abschnitten der Gelenkzapfen 7, die Lappen 25 in Ringnuten 26 mit Spiel ein und kommen mit den inneren Begrenzungsflächen 27 der Ringnuten 26 zur Anlage7 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. Preferably, in order to avoid portions of the pivot pins 7 projecting beyond the side cheeks 6, the tabs 25 play in 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 Umfangsfl che je einen Ansatz oder eine Ausdrückung 28, die über von der Frei¬ gabestellung und der Arbeitsstellung des Buchsenleisten- gehäuses versetzten Durchführungsöffnungen 29 in hin- terschnittene Ringnuten 30 eintauchen und ein freies Schwenken der Doppelhebel 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 peripheral surface, which extends from the free position and the working position of the socket strip Immerse the through openings 29 in the undercut ring grooves 30 and allow the double 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.
