Abstract

1. Plug-in connector having pressure contacts, having a housing which comprises a socket and a plug and, in the plugged condition, is held together by a bayonet joint, the socket housing (1) consisting of anti-magnetic, stainless steel, and bayonet grooves (2) extending on the socket housing, and associated bayonet pins being provided on the plug housing, characterized in that the plug housing (4) consists of aluminium or brass, providing good electrical conductivity, and in that the bayonet pins (5, 6, 7) are formed of wear resistant material and are placed in the plug housing (4).

Description

Gegenstand der Neuerung ist ein aus Do-se und Stecker bestehendes Gehäuse für Steckverbinder mit Druckkontakten, das im gesteckten Zustand mit einem Bajonettverschluß zusammengehalten wird, wobei eine oder mehrere Bajonettnuten auf dem Dosengehäuse aus antimagnetischem, rostfreien Stahl verlaufen.The subject of the innovation is a housing for plug connectors with pressure contacts, which is held together when plugged in with a bayonet lock, one or more bayonet grooves running on the socket housing made of antimagnetic, stainless steel.

Bei Steckverbindern der oben beschriebenen Art besteht die Schwierigkeit, daß die Forderung nach einer Mindestzahl von Steckzyklen bisher nur durch Verwendung von Gehäuseteilen aus antimagnetischem, rostfreiem Stahl zu verwirklichen war. Andererseits war es mit diesen Materialien nicht möglich, die häufig geforderte hohe Abschirmwirkung zu erzielen. So erreicht man bei einem bestimmten Steckertyp bei Verwendung von Stahl der Sorte xl2CrNi 188 für Stecker und Dose lediglich eine Schirmwirkung von nicht ganz 60 dB. Die häufig geforderte Schirmwirkung von mehr als 70 dB war dabei nur mit besonderen Bemühungen zu verwirklichen. Die Verwendung von gutleitendem Aluminium für Stecker und Dose scheiterte an der geforderten Lebensdauer nach Steckzyklen.With connectors of the type described above, there is the difficulty that the requirement for a minimum number of mating cycles could previously only be met by using housing parts made of antimagnetic, stainless steel. On the other hand, it was not possible with these materials to achieve the frequently required high shielding effect. With a certain connector type, when using steel of the xl2CrNi 188 type for connectors and sockets, the shielding effect is not quite 60 dB. The often required shielding effect of more than 70 dB was only possible with special efforts realize. The use of highly conductive aluminum for plugs and sockets failed due to the required service life after mating cycles.

Der Neuerung liegt die Aufgabe zugrunde, einen Steckverbinder anzugeben, der sowohl die erforderliche Lebensdauer als auch die geforderte Abschirmung erbringt.The innovation is based on the task of specifying a connector that provides both the required service life and the required shielding.

Diese Aufgabe wird gemäß der Neuerung dadurch gelöst, daß bei Steckverbindern der eingangs beschriebenen Art in das elektrisch gut leitende Steckergehäuse aus Aluminium oder Messing ein oder mehrere Bajonettstifte aus verschleißfesten Material eingesetzt sind. Da der schnelle Verschleiß von Steckerteilen aus Aluminium. gewöhnlich durch Abrieb im Bajonettverschluß auftritt, ermöglicht es die Lehre der Neuerung, für den Bajonettverschluß Stahlteile zu verwenden, während das Steckergehäuse als Aluminium aufgrund der verbesserten Leitfähigkeit die erforderliche Abschirmung sicherstellt.This object is achieved according to the innovation in that one or more bayonet pins made of wear-resistant material are used in connectors of the type described in the electrically well-conductive connector housing made of aluminum or brass. Because the quick wear of connector parts made of aluminum. usually occurs due to abrasion in the bayonet fitting, the teaching of the innovation makes it possible to use steel parts for the bayonet fitting, while the connector housing as aluminum ensures the required shielding due to the improved conductivity.

Die Fig. zeigt in zum Teil schematischer Darstellung ein Ausführungsbeispiel eines Steckverbinders nach der Neuerung. Mit 1 ist das herkömmlich aus rostfreiem, antimagnetischem Stahl gefertigte Dosengehäuse bezeichnet, das drei Bajonettnuten trägt, deren eine in der Fig. dargestellt und mit 2 bezeichnet-ist. Der Steckerkörper 4 ist teilweise geschnitten dargestellt, um die Lage von drei Bajonettstiften darzustellen. Die Bajonettstifte 5 greifen in die im linken Teil der Fig. nicht erkennbaren Bajonettnuten ein, während der Bajonettstift 7 in die Bajonettnut 2 eingreift.The figure shows a partially schematic representation of an embodiment of a connector according to the innovation. 1 with the conventionally made of rustproof, antimagnetic steel can housing, which carries three bayonet grooves, one of which is shown in the figure and is designated by 2. The plug body 4 is shown partially cut to show the position of three bayonet pins. The bayonet pins 5 engage in the bayonet grooves, which cannot be seen in the left part of the FIG., While the bayonet pin 7 engages in the bayonet groove 2.
