Description

Die Erfindung bezieht sich auf ein Verbindungssystem für elektrische Steckbuchsen nach dem Oberbegriff des Anspruchs 1.The invention relates to a connection system for electrical sockets according to the preamble of claim 1.

Es sind Verbindungssysteme für elektrische Einheiten, wie Steckbuchsen usw. bekannt geworden (DE-A-30 46 758), bei denen die die Buchse aufnehmenden Gehäuse durch gegeneinander in Eingriff bringbare Rastmittel nach Art einer Nut/Feder-Verbindung lösbar aneinander gehalten sind. Zum Festsetzen der Buchse im Gehäuse, insbesondere zum Halten der Buchse beim Verbinden mit einem Stecker sind Vorsprünge vorgesehen, die gehäuseseitig angeformt oder durch aufklemmbare Zusatzteile gebildet werden. Derartig ausgeführte Gehäuse für elektrische Buchsen bedingen aufgrund der getrennten Mittel zum Halten der Buchse sowie zum Verbinden der Gehäuse aneinander einen relativ großen baulichen Aufwand.Connection systems for electrical units, such as sockets, etc. have become known (DE-A-30 46 758), in which the housings receiving the socket are detachably held together by latching means which can be brought into engagement in the manner of a tongue and groove connection. To fix the socket in the housing, in particular to hold the socket when connecting to a plug, projections are provided, which are molded on the housing side or formed by additional parts that can be clamped on. Such housings for electrical sockets require a relatively large amount of construction work due to the separate means for holding the socket and for connecting the housings to one another.

Die US-A-3 701 087 zeigt Klemmbuchsen, welche seitlich Rastmittel zur Verbindung untereinander aufweisen.US-A-3 701 087 shows clamping bushes which have latching means on the side for connection to one another.

Aufgabe der Erfindung ist es, ein Verbindungssystem der eingangs genannten Art zu schaffen, das bei guter Wirksamkeit und Handhabung mit einfachen Mitteln zu realisieren ist.The object of the invention is to provide a connection system of the type mentioned which can be implemented with simple means with good effectiveness and handling.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved by the features of claim 1. The dependent claims contain further advantageous features.

Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, das die Gehäuse durch angeformte Rastnasen in einfacher Weise zusammenklipbar sind.The main advantages achieved by the invention are that the housings can be clipped together in a simple manner by means of molded catches.

Gleichzeitig dienen die Rastnasen zum Halten und Festsetzen der Steckbuchsen im Gehäuse, so daß keine zusätzlichen Arretiermittel mehr erforderlich sind. Es können durch die Rastmittel in einfacher Weise beliebig viele Gehäuse miteinander zu einer Funktionseinheit verbunden werden, wobei dann die gesamte Einheit über die noch verbleibende freie Rastnase z. B. an einer Aufbauwand eines Kraftfahrzeug festsetzbar ist. Vorteilig ist es außerdem, daß nur ein einstückiges Basisteil zur Anwendung kommt, was die Lagerhaltung vereinfacht und entsprechend der Erfordernisse z. B. eine zehnpolige, zwanzigpolige usw. Einheit herstellbar ist.At the same time, the locking lugs serve to hold and fix the sockets in the housing, so that no additional locking means are required. Any number of housings can be connected to one another in a simple manner by the latching means to form a functional unit, in which case the entire unit via the remaining free latching lug z. B. can be fixed to a body wall of a motor vehicle. It is also advantageous that only a one-piece base part is used, which simplifies storage and according to the requirements, for. B. a ten-pin, twenty-pin, etc. unit can be produced.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.

Es zeigen :

  • Fig. 1 einen Querschnitt durch mehrere nicht miteinander verrastete Isoliergehäuse eines Verbindungssystems und
  • Fig. 2 eine Darstellung im Schnitt gemäß Fig. 1 durch zwei miteinander verrastete Gehäuse mit innenliegend gehaltenen und zwischen Vorsprüngen festgesetzten Buchsen.
Show it :
  • Fig. 1 shows a cross section through a plurality of non-locked insulating housing of a connection system and
  • Fig. 2 is a sectional view of FIG. 1 through two interlocked housing with internally held and fixed between projections bushes.

Das Verbindungssystem 1 umfasst mehrere über Rastmittel 2 und 3 miteinander verbundene Isoliergehäuse 4. Innerhalb des Gehäuses 4 ist in einer Ausnehmung 5 eine Steckbuchse 6 angeordnet. Diese umfasst elektrische Leitelemente 7, die mit einem weiteren elektrischen Leitelement 8 eines von außen einsetzbaren Steckers 9 verbunden wird.The connection system 1 comprises a plurality of insulating housings 4 connected to one another via latching means 2 and 3. A socket 6 is arranged in a recess 5 within the housing 4. This comprises electrical guide elements 7 which are connected to a further electrical guide element 8 of a plug 9 which can be used from the outside.

Jedes Isoliergehäuse 4 weist die Elemente der zusammenwirkenden Rastmittel 2 und 3 auf. Das Rastmittel 2 umfaßt eine hakenförmige Nase 10, die an einer Seitenwand 11 des Gehäuses 4 angeformt ist. An der gegenüberliegenden Wand 15 des gleichen Gehäuses 4 ist eine Öffnung 12 vorgesehen. Zum Verbinden von zwei Gehäusen rastet die Nase 10 in die Öffnung 12 ein, die korrespondierend zu dieser im benachbart anschließenden Gehäuse angeordnet ist.Each insulating housing 4 has the elements of the interacting latching means 2 and 3. The locking means 2 comprises a hook-shaped nose 10 which is integrally formed on a side wall 11 of the housing 4. An opening 12 is provided on the opposite wall 15 of the same housing 4. To connect two housings, the nose 10 snaps into the opening 12, which is arranged corresponding to this in the adjoining housing.

Das weitere Rastmittel 3 ist am unteren Gehäuserand 13 einer Seitenwand vorgesehen und besteht aus einer nutförmigen Aufnahme 14. Diese ist gegenüberliegend der die Nase 10 aufnehmenden Wand 15 des Gehäuses 4 angeordnet, wie auch Fig. 1 zeigt.The further locking means 3 is provided on the lower housing edge 13 of a side wall and consists of a groove-shaped receptacle 14. This is arranged opposite the wall 15 of the housing 4 receiving the nose 10, as also shown in FIG. 1.

Zum Zusammensetzen mehrerer Gehäuse 4 zu einer Einheit wird jeweils das untere Randteil 13 der gestreckt ausgeführten Wand 11 eines anschließenden Gehäuses in die nutförmige Aufnahme 14 eingesteckt und in dieser formschlüssig gehalten.To assemble a plurality of housings 4 to form a unit, the lower edge part 13 of the stretched wall 11 of a subsequent housing is inserted into the groove-shaped receptacle 14 and held there in a form-fitting manner.

Die Buchse 6 ist mit ihrem unteren dem Stecker 9 zugerichteten Ende 21 an gehäuseseitigen seitlichen Vorsprüngen 16 und 17 abgestützt. An ihrem oberen abgekehrten Ende 22 weist die Buchse 16 eine Kontaktschulter 18 sowie eine abgespreizte federnde Verriegelungszunge 19 auf.The socket 6 is supported with its lower end 21 facing the plug 9 on side projections 16 and 17 on the housing side. At its upper distal end 22, the socket 16 has a contact shoulder 18 and a spread-out resilient locking tongue 19.

Die Kontaktschulter 18 ist gegenüber dem Grundkörper der Buchse 6 abgewinkelt und wird bei miteinander verbundenen Gehäusen von der Rastnase 10 eines anschließenden Gehäuses übergriffen und stützt sich an dieser haltend ab.The contact shoulder 18 is angled relative to the base body of the socket 6 and, in the case of interconnected housings, is overlapped by the latching lug 10 of a subsequent housing and is supported on it in a holding manner.

An einem gegenüberliegend der eingeführten Rastnase 10 bzw. der Öffnung 12 angeformten festen Vorsprung 20 der Gehäusewand 11 stützt sich die Verriegelungszunge 19 der Buchse 6 ab.The locking tongue 19 of the bushing 6 is supported on a fixed projection 20 of the housing wall 11 which is formed opposite the inserted latching lug 10 or the opening 12.

Somit ist die Buchse 6 einerseits zwischen den unteren Vorsprüngen 16 und 17 und andererseits zwischen dem oberen Vorsprung 10 (Rastnase) und dem Vorsprung 20 eingeklemmt gehalten, so daß bei Zug- und Druckeinwirkung auf die Buchse ein sicherer Halt innerhalb des Gehäuses gewährleistet ist.Thus, the socket 6 is held on the one hand between the lower projections 16 and 17 and on the other hand between the upper projection 10 (locking lug) and the projection 20, so that a secure hold is guaranteed within the housing when subjected to tension and pressure.

Nach einer alternativen Ausführung kann die Rastnase auch allein zum Halten der Buchse ausgebildet sein. Die Isoliergehäuse sind dann über Rastmittel zusammensteckbar, bei denen keine gleichzeitige Festsetzung der Buchse im Gehäuse erfolgt.According to an alternative embodiment, the locking lug can also be designed to hold the socket alone. The insulating housing can then be plugged together using latching means, in which there is no simultaneous fixing of the socket in the housing.
