'' Electrical contact and housing installation

The present invention relates to electrical contact housing internals for plug and socket connections and plug and socket connections for such internals.

In the case of electrical contact - built-in housings made of two-part housings made of resilient insulating material, in which each part of the housing has a

implementation has an electrical contact contains, and one of the housing parts contains a connector and the other housing part contains a connector socket, it has been found that difficulties in Connecting the plugs and sockets - contacts occur 'when you put the housing parts together, because of less Misalignment between the plug and the socket caused by the overall effect of manufacturing tolerances arise on the housing parts. Since a fairly precise axial alignment of the plug and socket is required is, in order to effect a proper connection of the plug in the socket, it has been proposed that the plugs and Arrange socket contacts in their respective housing parts so that limited relative movement between the contacts and the housing parts is allowed, whereby when connecting the housing parts Small movements of the contacts can be compensated for in order to achieve the necessary alignment of the connector and the Allow socket. Difficulties arose in obtaining a fixed arrangement of the connector and Socket contacts in housing bushings and when establishing a satisfactory plug and socket connection, which 'is easy and cheap to manufacture.

The stop 1 is exactly opposite the Shaped slot 5, and rearward to the stop is the socket S with an outwardly directed Protrusion 6 formed in the shape of a pit also exactly opposite the open seam.

To the rear of the projection 6 has the Body B further projections 10, which are uniformly spaced around the circumference of the body part B around lie, three in number. As can be seen from Figure 4- - is one of the projections 10 in the axial direction the socket with the projection 6 in a line. '

The body B of the plug P has a rounded nose in a completely hemispherical shape at its front end Shape and "has in the same way as the socket body an integrally formed stop 1 at the rear to the stop 1, the body B of the plug P is provided with a pair of projections 11 and rearward to the projections 11 with a; further projection 12, the front jumps 11 and M2 at the same distance on the circumference around the connector P lie around and the projection 12 is aligned with the stop 1 in the axial direction of the plug is.

With reference now to the electrical contact - housing installation according to Figure 7, the housing consists of two connecting parts H made of resilient insulating material, and each part is provided with a housing bushing 3 a socket part S, the plug engaging in a connecting manner in the front end of the socket.

Passage section with enlarged diameter, The socket S is arranged so that its body B passes through the reduced diameter portion extends, wherein the stop 1 engages in the front abutment projection, which by a annular lip 7 is determined · The projection 6 engages the rear Ans chi agsvor jump 8, so that the stop 1 and the projection 6 by engaging the projections of the parts of reduced diameter a mutual movement between the socket and the housing in the longitudinal direction of the socket resist. Reach the projection 6 from the rear the projections 10 in the side 9 of the housing lead-through and serve to stabilize the contact in the housing. The section of the housing penetration The reduced diameter is tapered at the front, around the socket body at a restricted Capture space near the front end of the section. Through this arrangement is it is possible that the bushing in the implementation by the resilient deformation of the section with slightly tilts when the diameter is reduced.

The plug part P is arranged in the implementation of its housing part in a similar manner
