Description

Die Erfindung betrifft eine elektrische Kupplungsvorrichtung mit einer an einem Geräterahmen fest angeordneten Messerleiste und einem in Lager des Geräterahmens mittels zwei gleichachsig im Abstand nebeneinander ausgebildeten Gelenkzapfen anhängbaren Gehäuse mit einer in diesem untergebrachten Buchsenleiste und mit am Geräterahmen vermittels angelenkten in Kulissennuten des Buchsenleistengehäuses mit Kulissensteinen einbringbaren Hebeln zum Anschwenken des Buchsenleistengehäuses an den Geräterahmen sowie an Geräterahmen und Buchsenleistengehäuse angeordneten Codiermitteln.The invention relates to an electrical coupling device with a fixedly arranged on a device frame male connector and in the bearing of the device frame by means of two axially spaced joint pins attached to each other with a housing accommodated in this and with the device frame by means of levers which can be inserted into the slot grooves of the female connector housing with sliding blocks for pivoting the socket strip housing onto the device frame as well as coding means arranged on the device frame and socket strip housing.

Bei elektrischen Kupplungen dieser Art (EP 0 119 951 A1) ist zu Codierzwecken bekannt, im Bereich der drehbaren Halterung von Steckerteile aufweisenden Gehäusen und Geräterahmen an diesen ineinandergreifende Codierstücke anzuordnen. Hierzu weist das an einem Kupplungsteil vorgesehene Codierstück einen Zylinderabschnitt auf, der in mit einem hohlzylindrischen Abschnitt versehenen anderen Codierstück des anderen Kupplungsteil einschwenkbar ist. Abgesehen davon, daß die Codierstücke schwierig herzustellen sind, bedürfen sie auch aufwendige Befestigungsmaßnahmen an den Kupplungsteilen. Außerdem hat ein Wechsel der Codierung erhebliche Montagearbeiten zur Voraussetzung.In electrical couplings of this type (EP 0 119 951 A1) it is known for coding purposes to arrange interlocking coding pieces in the area of the rotatable mounting of housings and device frames having plug parts on them. For this purpose, the coding piece provided on a coupling part has a cylinder section which can be pivoted into the other coding piece of the other coupling part provided with a hollow cylindrical section. In addition to the fact that the coding pieces are difficult to manufacture, they also require complex fastening measures on the coupling parts. In addition, changing the coding requires considerable assembly work.

Es ist Aufgabe der Erfindung, eine einfache und sichere Codierung für Kupplungsvorrichtungen zu schaffen, die auch variabel ist.It is an object of the invention to provide a simple and secure coding for coupling devices that is also variable.

Erfindungsgemäß ist dies dadurch erreicht, daß das Buchsenleistengehäuse zwischen den Gelenkzapfen nebeneinander an ausbrechbaren Konturen vorbereitete Schlitzungen mit in Steckrichtung vorne offenen Enden aufweist und daß der Geräterahmen zwischen den Gelenkzapfenlagern mindestens einen in Geräterahmenöffnungen auswechselbar fest eingesetzten und in Schlitzungen des Buchsenleistengehäuses einbringbaren Codierstift trägt. Bevorzugt ist dabei das Buchsenleistengehäuse zwischen den beiden Gelenkzapfen durch einen Flachstreifen gebildet, der die durch ausbrechbare Konturen vorbereitete Schlitzungen aufweist. Auf diese Weise sind die Mittel zur Codierung der Kupplungsteile einfach und ohne nachteilige Vergrösserung von Geräterahmen und/oder Gehäuse ausbildbar. Außerdem sind die vorbereiteten Schlitzungen und der Codierstift ohne großen Aufwand an Werkzeugen ausbildbar.According to the invention, this is achieved in that the socket strip housing has slits prepared next to each other on break-out contours between the hinge pins and ends open in the direction of insertion, and in that the device frame between the hinge pin bearings carries at least one coding pin which is interchangeably fixed in the device frame openings and can be inserted into slots in the socket strip housing. The socket strip housing between the two hinge pins is preferably formed by a flat strip which has the slits prepared by breakable contours. In this way, the means for coding the coupling parts can be formed easily and without disadvantageous enlargement of the device frame and / or housing. In addition, the prepared slits and the coding pin can be formed with little effort on tools.

In Ausgestalung der Kupplungsvorrichtung ist vorgesehen, daß die Kulissennuten am Einführende für die Kulissensteine der Hebel jeweils einen sich konisch verjüngenden Kulissenteil mit einem anschließenden quer erstreckenden Kulissennutenteil aufweisen und daß die quer erstreckenden Kulissennutenteile hintereinander mit zwei als Rasten für die Kulissensteine dienende bogenförmige Einziehungen als Vorverrastungs- und Verriegelungsstellung versehen sind, wobei zur Bildung eines Überhubs sich die die Verriegelungsstellung bildenden Einziehungen zweckmäßig vor der senkrechten Verbindungslinie der Mittelachse der Zapfen zum Geräterahmen erstrecken. Beim Ansetzen des Gehäuses an den Geräterahmen ermöglicht eine Teilschwenkung des Gehäuses in Verbindung mit den die Kulissensteine tragenden Doppelhebeln durch Eingreifen der Kulissensteine in die eine Einziehung eine Vorverrastung des Gehäuses, aus der heraus durch weiteres Abschwenken der Doppelhebel und Verbringen der Kulissensteine in die andere Einziehung eine Verriegelung des Gehäuses am Geräterahmen erfolgen kann.In the design of the coupling device, it is provided that the link grooves at the insertion for the link blocks of the levers each have a conically tapering link part with a subsequent transverse link slot part and that the transverse link slot parts one behind the other with two arched recesses serving as catches for the link blocks as pre-latching and the locking position are provided, the recesses forming the locking position expediently extending in front of the vertical connecting line of the central axis of the pins to the device frame to form an overstroke. When attaching the housing to the device frame, a partial pivoting of the housing in connection with the double levers carrying the sliding blocks enables the sliding blocks to engage in a retraction of the housing, out of which by further pivoting the double levers and moving the sliding blocks in the other retraction, the housing can be locked on the device frame.

Schließlich ist noch vorgesehen, die beiden Hebel als Doppelhebel mit verschieden langen Hebelarmen zu gestalten und durch einen Steg miteinander zu verbinden, wobei die Hebel mittels der Zapfen am Geräterahmen lagern, während die kurzen Hebelarme die Kulissensteine tragen. Nach bevorzugter Ausführung können die Hebelarme und der Steg durch einen einstückigen Formteil und die Zapfen und/oder die Kulissensteine zu Stabilitätsverbesserungen durch an den Hebelarmen angeordnete tiefgezogene Ansätze gebildet sein.Finally, it is also provided to design the two levers as double levers with lever arms of different lengths and to connect them to one another by means of a web, the levers being supported on the device frame by means of the pins, while the short lever arms carry the sliding blocks. According to a preferred embodiment, the lever arms and the web can be formed by a one-piece molded part and the pins and / or the sliding blocks for stability improvements by deep-drawn approaches arranged on the lever arms.

Zur Vermeidung von einem unbeabsichtigten Heraustreten der Zapfen aus den Zapfenlagern ist vorgesehen, an den die Zapfen bildenden Ansätze je einen abbiegbaren Lappen anzuschneiden, die in sich an den Zapfenlagern anschließenden Ringnuten als axiale Abstützglieder für die Doppelhebel eintauchen.To avoid unintentional emergence of the pins from the pin bearings, it is provided to cut a bendable tab on each of the lugs forming the pins, which plunge into ring grooves adjoining the pin bearings as axial support members for the double levers.

Darüberhinaus läßt sich eine axiale Fixierung der Doppelhebel am Geräterahmen auch dadurch erreichen, daß die die Zapfen bildenden Ansätze je eine Ausdrückung und die zugeordneten Zapfenlager, zu den Arbeits- und Ruhestellungen der Doppelhebel versetzt, je eine sich an den Zapfenlagern anschließende Durchführungsöffnung für die Ausdrückungen der Ansätze aufweisen. Das Einbringen bzw. das Entnehmen der Ansätze aus den Zapfenlagern ist einfach nach Gegenüberstellung von Ausdrückungen und Durchführungsöffnungen für diese möglich.In addition, an axial fixation of the double levers on the device frame can also be achieved in that the lugs forming the pegs each offset and the associated peg bearings, to the working and rest positions of the double levers, each have a through opening adjoining the peg bearings for the expressions of the Have approaches. The insertion or removal of the lugs from the journal bearings is possible simply by juxtaposing expressions and through openings for them.

a coupling device in side view, partially in section,
This is followed by pages 4 to 7 of the original documents.

Die Zapfen 7 der Doppelhebel 8 sind, wie die Fig. 4 und 5 erkennen lassen, in Ausnehmungen 32 der Seitenwangen 6 gelagert, die im Bereich der freien Enden der Zapfen 7 im lichten Durchmesser vergrößert sind. Die so zugänglichen Zapfen 7 nehmen in einer Nut 33 jeweils einen Sprengring 34 zur axialen Fixierung der Hebelarme 8', 8'' an den Seitenwangen 6 auf.The pins 7 of the double lever 8 are, as can be seen in FIGS. 4 and 5, mounted in recesses 32 in the side cheeks 6, which are enlarged in the area of the free ends of the pins 7 with a clear diameter. The pins 7 accessible in this way each receive a snap ring 34 in a groove 33 for axially fixing the lever arms 8 ′, 8 ″ to the side cheeks 6.

Bei Einschieben der Gelenkzapfen 11 in die Gelenkzapfenlager nimmt das Buchsenleistengehäuse 2 zunächst die in Fig. 1 strichpunktierte Stellung ein. Durch nachfolgendes Schwenken des Buchsenleistengehäuses 3 in Richtung Geräterahmen 1 verschieben sich die Zapfen 9 in den konischen Kulissennutenteilen 13', wobei durch Anlaufen der Zapfen 9 an Schrägen 23 eine Teilschwenkung der Doppelhebel 8 in Uhrzeigerdrehrichtung erfolgt. Die Zapfen 9 kommen mit einer Einziehung 24 zur Wirkung und das Buchsenleistengehäuse 3 ist am Geräterahmen 1 vorverrastet gehalten. Bei weiterem Abschwenken der Doppelhebel 8 in Uhrzeigerdrehrichtung bewegen sich die Zapfen 9 über den Teil 13'' und drücken das Buchsenleistengehäuse 3 in die in Fig. 1 gezeigte kuppelstellung an den Geräterahmen 1. In dieser Stellung greifen die Zapfen 9 in die anderen Einziehungen 25 ein. Durch Anordnung dieser Einziehungen 25 vor der senkrechten Verbindungslinie zwischen den Mittelachsen der Zapfen 7 und dem Geräterahmen 1 ist ein überhub geschaffen, der zu einer Verriegelung führt und ein selbsttägiges Lösen des Buchsengehäuses 3 vom Geräterahmen 1 verhindert. Die Doppelhebel 8 greifen in der Kuppelstellung von Buchsengehäuse und Geräterahmen mit einem Betätigungsansatz 26 in eine Ausnehmung 27 des Buchsenleistengehäuses 3 ein. Durch Einschieben eines geeigneten Werkzeuges, z. B. Schraubenzieher in die Ausnehmung 27 ist der Doppelhebel 8 rückschwenkbar und das Buchsenleistengehäuse 3 kann vom Geräterahmen 1 abgenommen werden. Die zwischen den Einziehungen 24, 25 verbleibenden Erhöhungen 35 führen zu einem fühlbaren Widerstand beim Zusammenwirken mit den Zapfen 9 in der Art eines Druckpunktes.When the pivot pin 11 is inserted into the pivot pin bearing, the socket strip housing 2 initially assumes the position shown in broken lines in FIG. 1. Subsequent pivoting of the socket strip housing 3 in the direction of the device frame 1 causes the pins 9 to move in the conical link groove parts 13 ', partial pivoting of the double levers 8 in the clockwise direction of rotation taking place due to the pins 9 running on bevels 23. The pins 9 come into effect with a retraction 24 and the socket strip housing 3 is held pre-locked on the device frame 1. When the double lever 8 is pivoted further in the clockwise direction of rotation, the pins 9 move over the part 13 ″ and press the female connector housing 3 into the coupling position shown in FIG. 1 on the device frame 1. In this position, the pins 9 engage in the other recesses 25 . By arranging these indentations 25 in front of the vertical connecting line between the central axes of the pins 7 and the device frame 1, an overstroke is created, which leads to a lock and prevents the socket housing 3 from automatically detaching from the device frame 1. The double levers 8 engage in the coupling position of the socket housing and device frame with an actuating projection 26 in a recess 27 of the socket strip housing 3. By inserting a suitable tool, e.g. B. screwdriver in the recess 27, the double lever 8 can be pivoted back and the socket strip housing 3 can Device frame 1 can be removed. The elevations 35 remaining between the indentations 24, 25 lead to a noticeable resistance when interacting with the pins 9 in the manner of a pressure point.

Das Buchsenleistengehäuse 3 weist zwischen den beiden Gelenkzapfen 11 einen Flachstreifen 28 auf, der eine Anzahl an vorbereitete Konturen 29 ausbrechbare Schlitzungen 30 aufweist. Den Schlitzungen 30 ist am Geräterahmen 1 mindestens ein Stift 31 auswechselbar fest bzw. fest zugeordnet, so daß durch entsprechendes Zusammenwirken von Schlitzungen 30 und Stiften 31 eine Codierung des Buchsenleistengehäuses 3 erzielbar ist. Es versteht sich, daß eine beliebige Anzahl Stifte 31 gleichzeitig einer Anzahl Schlitzungen 30 zugeordnet sein kann.The socket strip housing 3 has a flat strip 28 between the two pivot pins 11, which has a number of prepared contours 29 slits 30 that can be broken out. At least one pin 31 is interchangeably permanently or permanently assigned to the slots 30 on the device frame 1, so that coding of the socket strip housing 3 can be achieved by corresponding interaction of slots 30 and pins 31. It is understood that any number of pins 31 can be assigned to a number of slots 30 at the same time.

Bei den Ausführungsbeispielen der Fig. 6 bis 12 sind die Zapfen 7 und die Zapfen 9 durch tiefgezogene Ansätze (Fig. 7) gebildet und damit einstückig mit den Hebelarmen 8', 8'' ausgeführt. In den Fig.9 und 10 sind an den Zapfen 7 je ein Lappen 36 angeschnitten, die durch Zurückbiegen ein unbeabsichtigtes Herausgleiten der Zapfen 7 aus den Zapfenlagern 37 verhindern. Bevorzugt tauchen zur Vermeidung von über die Seitenwangen 6 überstehenden Abschnitten der Zapfen 7, die Lappen 36 in Ringnuten 38 mit Spiel ein und kommen mit den inneren Begrenzungsflächen 39 der Ringnuten 38 zur Anlage.In the exemplary embodiments in FIGS. 6 to 12, the pins 7 and the pins 9 are formed by deep-drawn lugs (FIG. 7) and are therefore made in one piece with the lever arms 8 ′, 8 ″. In FIGS. 9 and 10, a tab 36 is cut onto each of the pins 7, which prevent the pins 7 from inadvertently sliding out of the pin bearings 37 by bending back. To avoid portions of the pins 7 projecting beyond the side cheeks 6, the tabs 36 preferably dip into the annular grooves 38 with play and come into contact with the inner boundary surfaces 39 of the annular grooves 38.

Beim Ausführungsbeispiel der Fig. 11 und 12 tragen die Zapfen 7 im Bereich der Umfangsfläche je einen Ansatz oder Ausdrückung 40, die über von der Freigabestellung und der Arbeitsstellung des Buchsenleistengehäuses 3 versetzten Durchführungsöffnungen 41 in hinterschnittene Ringnuten 42 eintauchen und ein freies Schwenken der Doppelhebel 8 erlauben. Vermittels der Ansätze 40 und der Ringnuten 42 sind die Zapfen 7 mit Spiel an den Seitenwangen axial fixiert, wodurch ein unbeabsichtigtes Herausgleiten der Zapfen 7 aus den Zapfenlagern 37 verhindert ist.In the embodiment of FIGS. 11 and 12, the pins 7 each have an extension or expression 40 in the area of the peripheral surface, which plunge into undercut ring grooves 42 via feed-through openings 41 offset from the release position and the working position of the socket strip housing 3 and allow the double lever 8 to pivot freely . By means of the lugs 40 and the annular grooves 42, the pins 7 with play on the Sidewalls axially fixed, thereby preventing the pins 7 from inadvertently sliding out of the pin bearings 37.
