MODULAR ELECTRICAL CONNECTOR

The present invention relates to an electrical plug-element (1a-1e) comprising at least one socket module (2a-2e) with a receptacle (5) for a mating plug-element, the receptacle (5) opens towards a plug-direction (Z) of the plug-element (1a-1e), is formed between at least two wall sections (4, 4') of the socket module (2a-2e) which extend essentially in parallel to a length direction (X) of the plug-element (1a-1e), and accommodates at least one contact support area (27) which extends along the length direction (X) and at least partially faces into the plug-direction (Z), and at least one mounting module (3a-3i) having a holding section (30) attached to a lateral side of the socket module (2a-2e), the lateral side extending essentially in parallel to the plug- direction (Z), and a mounting section (16a-16i) providing a mounting organ (17a-17i) adapted to be fastened to a substrate (100). Further, the invention relates to a socket module (2a-2e), a mounting module (3a-3i) and to a kit comprising the socket module (2a-2e) and the mounting module (3a-3i), as well as to a method of equipping an electrical device with the plug-element (1a-1e).
