are known in the generic field (US-PS 3 761 869). In this known connector, the wires are placed between two parts of the connector and the Pieces put together, the wires being clamped.

The two-part embodiment has not proven itself, because the positioning of the wires and thus the exact controllable penetration of the contact elements into the Veins is almost impossible. One is in the. Result therefore switched to one-piece plugs (DE-OS 24 32 122 and DE-OS 27 53 822), although these connectors have significant disadvantages. E.g. the contact elements are individually pressed in after all wires have already been inserted into a slot. The veins can be sideways evade so that the contact can be disturbed.

In contrast, the invention has gone back a step and has the two-part embodiment of a Steckers took up again, but found a solution that optimally distributes functions guaranteed. There are no models from the field of penetration contacting technology.

According to a particular embodiment of the invention have the wire contact tongues 11 at their outer edges on bar-shaped material projections 11a, which in such a way are arranged that when the housing part 1 is locked to the plug part 2 in the wall of a Penetrate slot 22 and get caught there.

In the same way, on the connecting webs 12 or the plug contact webs 9 in the area of the passages 3 locking means, e.g. barb-shaped material projections 10a provided, which has a fixed positioning

ensure the contact elements 10 in the bearing block 5. In combination with the barb-shaped material projections 11a, when the housing part 1 is locked with the plug part 2, the parts 1 and 2 are also held together by the positioning means 11a and 10.

In addition, the positioning means 11a ensure that the contact is maintained almost unchanged remains because the wire contact tongues 11 are fixed in the wire block.

A major advantage of the invention compared to the prior art is that the contact elements IO sit immovably in their bearing block 5 and to Contact only the core block 19 is pushed onto the contact webs 11 without affecting the position of the Contact elements in the bearing block 5 is changed. From this Arrangement results in a controlled contact of the wires. This is the case with the known connectors which at least some of the contact elements for contacting had to be moved in their storage block, not possible.
