DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

The invention relates to an electrical connection of the type specified in the preamble of claim 1. In particular in the case of motor vehicles, cable harnesses are used whose male parts and female parts have a plurality of contact pins and contact sleeves respectively located side by side.


BACKGROUND OF THE INVENTION

In the case of the known connection of this type, the longitudinal guide elements between the end plate and the housing comprised guide pins projecting from the end plate which were displaceable in axial guide chambers in the housing. These guide chambers were produced by a raised area in the housing, above each tubular channel, which was used for insertion assembly of a contact sleeve. This resulted in the male part having a relatively large physical height. The sprung tongue was integrally formed in the housing interior on the inner surface of the tubular channel and did not allow any visual inspection of whether the contact sleeve insertion assembly was correct. Defects could arise during assembly of the components. The assembly of these components of the known male part was cumbersome and, above all, unsuitable for automation.


SUMMARY OF THE INVENTION

The invention is based on the object of developing a reliable electrical connection of the type stated in the preamble of claim 1, whose components can be assembled conveniently and are suitable for automation of the process. This is achieved according to the invention by the measures outlined in the descriptive part of claim 1, which have the following particular significance.
Special longitudinal guide elements between the end plate and the housing are avoided because the outer contour of the housing simply itself carries out the guide functions during longitudinal displacement of the cap. The assembly of the cap with the housing can be carried out conveniently without any cumbersome alignment of individual longitudinal guide elements, and the cap just needs to be placed over the housing, like a cover. This allows automatic assembly. The plugged-on cap also ensures the housing is encased and guarantees additional protection. This covering of the housing by the cap allows the sprung tongue to be produced particularly simply, namely by wall parts of the tubular wall of the housing itself. The tongue is thus located in the housing such that it can easily be seen from the outside, and this is also true in the extended position of the cap. It is thus possible to check visually during the insertion assembly of the contact sleeve whether the spring is pivoted about beyond the outer contour of the housing before, finally, in the defined assembly position of the contact sleeve in the housing, the spring is aligned again with the adjacent regions of the housing tubular wall. Incorrect or incomplete insertion assembly of the contact sleeve can be identified by the spring making no pivoting movement or the pivoting movement being inadequate. This can be reliably identified by visual probe means. Automation of the assembly can easily be implemented. After this inspection, the cap can be pushed into the final pushed-in position on the housing, where it covers the tongue and thus prevents the tongue springing out inadvertently. In this covered position, the cap locks the contact sleeve which has been inserted in the correct assembled position in the housing; it is thus used as a locking means for the assembled contact sleeve. On completion, the correct assembled position of all the components is ensured by the final electrical inspection of the complete male part. Incorrect results are prevented.
