ABSTRACT:
An electrical plug and socket connector includes a two-part connector frame (1) which can be affixed to an apparatus housing, and further includes a two-piece insulating body (4, 5) enclosed between the two frame parts (2, 3), which insulating body has a plurality of bores to accommodate contact elements (6, 7) in the form of plug pins, plug sockets, or the like, which contact elements are connectable to electrical conductors on the rear side of the connector. The insulating body includes a frontwardly disposed supporting and guiding plate (4) fabricated of thermoplastic plastic. The insulating body also includes a rear plate (5). In order to achieve a trouble-free seal, the rear plate of the insulating body is in the form of a sealing plate (5) of rubberlike elastic material, and this sealing plate (5) is particularly dimensioned with respect to the supporting and guiding plate (4), which supporting and guiding plate rests against the outwardly curved or flared flange (12) of the front part of the frame. Namely, the sealing plate (5) is so dimensioned with respect to the face of the supporting and guiding plate (4) which is directed toward it, that after the two frame parts (2, 3) are fastened together the edge region (13) of the sealing plate is held in compression against a supporting edge region (14) of the rear frame part (3), whereby a trouble-free seal is created.
