Abstract

A transfer plug system for electrical or electronic controls or devices having coding parts which correspond to one another mechanically and are attached at a cable housing as well as in the area of a counter-plug element, the coding parts being brought into engagement with one another and held by means of a shared locking element, the locking element thus operating to fulfill a dual function of coding for preventing faulty plugging and of fastening and locking the plug housing at plates or in a structural component part carrier.

Description

Die Erfindung bezieht sich auf eine mehrpolige elektrische Steckverbindung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a multi-pole electrical connector according to the preamble of claim 1.

Bekannt ist ein derartiqes System beispielsweise als sog. "Abgedeckter Steckschuh mit Verschlüsselung" bereits aus der DE-A-1 490 737 und offenbart dort schon die Doppelfunktion stiftförmiger und in eines der Steckerteile einsetzbarer Formstücke als Kodier- und zugleich Festsetzelementen für das Gegensteckerteil.Such a system is known, for example, as a so-called "covered plug-in shoe with encryption" from DE-A-1 490 737 and already discloses the double function of pin-shaped fittings which can be used in one of the plug parts as coding and fixing elements for the mating plug part.

Was bei dieser bekannten Ausführung allerdings die spezielle, technische Ausbildung anbelangt, so muß diese nicht nur als baulich sehr aufwendig angesehen werden, sondern auch in funktioneller Hinsicht als unbefriedigend, weil zum einen Steckung und Verriegelung im wesentlichen von der bei häufigem Gebrauch bekanntlich mehr und mehr nachlassenden Elastizität der Formstoffe der Abdeckung Gebrauch machen, und zum anderen gerade diese Abdeckung bei den üblicherweise mehreren Steckern pro Einheit nur unzureichend erkennen läßt, welche Kodierung zu welchem Stecker paßt und zudem überhaupt keine Sichtkontrolle darüber ermöglicht, ob bei einer Steckung an deren Ende tatsächlich das funktionell erforderliche Einrasten der Stifte in die verdeckt liegenden Hinterschneidungen stattgefunden hat.As far as the special, technical training is concerned with this known design, it must not only be considered to be structurally very complex, but also unsatisfactory from a functional point of view because, on the one hand, plugging and locking essentially become more and more common, as is known with frequent use make use of diminishing elasticity of the molded materials of the cover, and on the other hand this cover, in the case of the usually several plugs per unit, only insufficiently recognizes which coding fits with which plug and, moreover, does not allow any visual control as to whether this is actually the case at a plug at the end functionally required snapping the pins into the concealed undercuts has taken place.

Gleiches gilt im Prinzip und hinsichtlich der Kodierung auch für die bekannte Ausführung gemäß der DE-A-2 534 775, wobei hier allerdings zusätzlich noch die Verriegelungsfunktion der Kodierstifte völlig fehlt.The same applies in principle and with regard to the coding also for the known embodiment according to DE-A-2 534 775, although here the locking function of the coding pins is also completely absent.

Die Aufgabe der vorliegenden Erfindung soll es daher sein, ausgehend von der DE-A-1 490 737 eine mehrpolige Steckvorrichtung der eingangs genannten Art so weiterzubilden, daß eine sichere Verrastung zwischen der Messerleiste mit Führungsrahmen und dem Kabelstecker erreicht wird, wobei zudem noch eine optische Kontrolle für die Erreichung der Steckposition vorhanden sein soll.The object of the present invention should therefore be based on DE-A-1 490 737 to develop a multi-pin connector of the type mentioned so that a secure locking between the male connector with the guide frame and the cable connector is achieved, while also an optical Control for reaching the plug position should be available.

Gelöst wird diese Aufgabe gemäss dem kennzeichnenden Teil des Patentansprüches 1.This object is achieved in accordance with the characterizing part of patent claim 1.

Zwei Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und im folgenden näher erläutertTwo embodiments of the invention are shown in the drawings and explained in more detail below

Es zeigen:

  • Fig. 1 in ein Übergabestecksystem integrierte mehrpolige Steckvorrichtung in perspektivischer Darstellung

und
  • Fig. 2 eine Alternativausführung zu Fig. 1, ebenfalls in Perspektive,
  • Fig. 3 in vergrößertem Maßstab die Einzelheit bei Kreis "A" aus Fig. 1

und
  • Fig. 4 desgleichen aus Kreis "B" aus Fig. 2.
Show it:
  • Fig. 1 in a transfer plug system integrated multi-pin connector in a perspective view

and
  • 2 shows an alternative embodiment to FIG. 1, also in perspective,
  • 3 shows the detail at circle "A" from FIG. 1 on an enlarged scale

and
  • 4 likewise from circle "B" from FIG. 2.

Der in Fig.1 dargestellte - und vom Prinzip her analog auch für die Darstellung in Fig. 2 geltende - Grundaufbau eines Übergabestecksystems, weist folgende, bekannte Bauteile auf: Eine Leiterplatte 1 mit Messerleisten 2 mit jeweils einem Führungsrahmen 3 für die Frontsteckung eines Kabelsteckers, befestigt an einem sogenannten "motherboard" 4 mittels der in der Explosivdarstellung angedeuteten Verschraubungen 13, 14.The basic structure of a transfer connector system shown in FIG. 1 and, in principle, also analogously for the illustration in FIG. 2, has the following known components: a printed circuit board 1 with male connectors 2, each with a guide frame 3 for the front connection of a cable connector, attached to a so-called "motherboard" 4 by means of the screw connections 13, 14 indicated in the exploded view.

Ebenfalls in Explosivdarstellung in der linken Zeichnungshälfte ist der Kabelstecker mit einer Federleiste 6, bestückt mit bekannten Schneidklemmenkontaktstücken 11 und zwei Gehäusehalbschalen 8 und 9, die, wie die rechte obere Hälfte dieser Figur zeigt, im Zusammenbau mit dem Kabelführungsteil 7, das eigentliche Kabelsteckergehäuse 15 bilden, dargestellt. Es sind noch dessen Endform fixierende Rastlöcher 16a sowie Führungsnocken 17c an der Federleiste sowie dem Kabelführungsteil 7, welches letztlich noch zum Verteilen der aus dem Rundkabel 12 abzweigenden Einzelleiter 12a dient, vorhanden. Pos. 10 stellt hierbei einen ebenfalls bekannten Kabelbinder dar.Also in an exploded view in the left half of the drawing is the cable connector with a female connector 6, equipped with known insulation displacement contact pieces 11 and two housing half-shells 8 and 9, which, as the upper right half of this figure shows, in assembly with the cable guide part 7, form the actual cable connector housing 15 , shown. There are also locking holes 16a fixing its final shape, as well as guide cams 17c on the female connector and the cable guide part 7, which ultimately also serves to distribute the individual conductors 12a branching off the round cable 12. Pos. 10 represents a well-known cable tie.

Aus Fig. 1 bzw. Fig. 2, die sich nur dadurch von Fig. 1 unterscheidet, daß der Führungsrahmen 3a unmittelbar auf einer Leiterplatte 16 befestigt ist, ist zu ersehen, daß sowohl am Kabelsteckergehäuse 15, als auch im Rereich des Führungsrahmens 3 bzw. 3a Kodierstifte 5 vorgesehen sind.From Fig. 1 and Fig. 2, which differs from Fig. 1 only in that the guide frame 3a is attached directly to a circuit board 16, it can be seen that both on the cable connector housing 15, and in the area of the guide frame 3 or 3a coding pins 5 are provided.

Diese sind mit ihrem einen Ende 5' in Aufnahmeöffnungen 19 von am Führungsrahmen 3 bzw. 3a angebrachten Kodierleisten 18 mittels klammerförmig gespaltenen Verhakungen 5a verrastet.These are latched at their one end 5 'into receiving openings 19 of coding strips 18 attached to the guide frame 3 or 3a by means of hooks 5a split in the form of clips.

Die Kodierstifte 5 durchgreifen mit ihrem der Verhakung 5a gegenüberliegenden, freien Ende 5" jeweils mit einem zum Kabelsteckergehäuse 15 hin weisenden Nocken 20 eine der Aussparungen 17a von beiderseits am Kabelsteckergehäuse 15 angeformten Kodierleisten 17, die durch Ausbrechen von Stegen 17b entstehen und die in der Flucht F zu den Aufnahmeöffnungen 19 der Kodierleisten 18 liegen. Die Breite a jedes Nockens 20 entspricht dem Innenmaß b der jeweils zugehörigen Aussparung 17a und deren Abstand c vom Führungsrahmen 3 bzw. 3a ist derart bemessen, daß in verriegeltem Zustand (rechte obere Partie in Fig. 2), der jeweiligen Nocken 20 hinter eine entsprechende Abstufung 15a des Kabelsteckergehäuses 15 bzw. 21 eingreift.The coding pins 5, with their free end 5 ″ opposite the hooking 5a, each engage with a cam 20 pointing towards the cable connector housing 15 through one of the recesses 17a of coding strips 17 formed on both sides of the cable connector housing 15, which result from the breaking out of webs 17b and which are in flight F to the receiving openings 19 of the coding strips 18. The width a of each cam 20 corresponds to the internal dimension b of the respectively associated recess 17a and its distance c from the guide frame 3 or 3a is dimensioned such that in the locked state (upper right part in FIG. 2), the respective cam 20 engages behind a corresponding step 15a of the cable connector housing 15 or 21.

Die Kodierstifte 5 haben eine Doppelfunktion. Sie dienen sowohl der Kodierung, als auch der Verriegelung zusammen mit den Kodierleisten 17 und 18 und der Abstufung 15a des Kabelsteckergehäuse 15. Die Kodierleisten 18 sind am Führungsrahmen 3 bzw. 3a erhaben angeformt (Fig. 2) oder aufgesetzt (Fig. 1).The coding pins 5 have a double function. They serve both the coding and the locking together with the coding strips 17 and 18 and the gradation 15a of the cable connector housing 15. The coding strips 18 are formed on the guide frame 3 or 3a raised (Fig. 2) or attached (Fig. 1).
