Abstract: A carrier plate in the form of a flat plate having a first main surface and a second main surface facing away from the first main surface, these main surfaces being the surface sides of the plate having the largest surface area, and having first detent elements to which an electrical plug connector, having second detent elements, with its second detent elements is affixable via form-fit interlocking of the first detent elements with the second detent elements. Further relates an arrangement is provided having such a carrier plate and at least two electrical plug connectors, each of which has second detent elements. Also, an arrangement is provided having two such carrier plates and a plug connector as well as a mating plug connector, each of which has second detent elements.

Abstract: A housing of an electrical plug connector, which has the following features: at least one plug chamber, accessible from a plug face of the plug connector, into which a mating plug connector designed as the mating piece for the plug connector may be inserted; four circumferential walls, which surround at least the plug chamber on the circumferential side and extend in parallel to an insertion direction, in which the mating plug connector may be inserted into the plug chamber; at least one elastically resilient locking tab is formed on at least one circumferential wall for the purpose of locking the mating plug connector on the plug connector; the at least one locking tab is designed as a material tongue separated from the material of the circumferential wall by cutaway sections on both sides. An electrical plug connector is also provided, which includes the housing.
