BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention relates to a multiconnection. In a known plug and socket, the flat contact receptacles, which are arranged in three parallel rows in a contact carrier, engage with a catch tongue behind a catch edge of the contact carrier in the unlocking and locking positions of a locking plate. In the locking position of the plate, the flat contact receptacles are additionally secured by means of the plate. A disadvantage consists in that a complicated injection molding tool with telescoping needles is required for producing the catch edge and accordingly the contact carrier, the catch edge being constructed as an undercut. Such complicated tools require repairs to a relatively great extent.
Moreover, there is an increasing need for a plug and socket in which 50 or more individual plug-in connections are comprised and which can be plugged in or unplugged at once. It is a disadvantage that the plug and socket requires more and more space which is very limited chiefly in the installation space of motor vehicles.


SUMMARY OF THE INVENTION

The invention has the object of providing a multiconnection plug and socket which can be produced with simple tools and can be provided with smaller plug-in connection parts in order to save space.
It is advantageous that the contact carrier can receive more connection parts in the form of smaller box-shaped flat contact receptacles while retaining the same dimensions and in so doing makes do with spring contact chambers having smooth walls, but a smaller cross section. The spring contact chambers, and accordingly the contact carriers, can be produced more easily and with simpler tools. Such tools are substantially less needful of repairs and are suitable for economical large-series production. Moreover, the plugs can be used for a plug and socket with the desired number of connection parts simply by exchanging the contact carrier. Moreover, the flat contact receptacles can be held and secured in the contact carrier in their unlocking and locking positions solely by means of the safety plate.
It is particularly advantageous to provide the openings of the safety plate with projections and/or to use edge portions of the openings in such a way that the catch tongues and/or parts of the edge of the box-shaped portion of the flat contact receptacles contact the side of the safety plate facing in the plug-in direction in the unlocking and/or locking positions of the plate.
Moreover, a substantial advantage consists in that a mixed outfitting with larger and smaller socket parts for the multiconnection plug and socket is possible. For this purpose, the socket parts need not be ordered only in rows according to size. Larger and smaller socket parts can also be arranged in a mixed manner in one or more rows.
