Abstract
Abstract An electrical connector (12) includes an insulative housing (16) surrounded by conductive shield means (18, 20) and adapted to be mounted on a PC board (100). A mating portion (37) extends inward from a front surface (38) of the housing (16) which is covered by the shield (18, 20). A plurality of contacts (40) are disposed in the mating portion (37) and extend rearward for connecting to the PC board (100). The shield (18, 20) includes an opening (42)in its front face (22) for having a complementary plug connector inserted into the mating portion (37) of the housing (16). A grounding device (14) comprises a plate (50) having the similar configuration of the front face (22) of the shield (18), and engagement tangs (54) projecting from a bottom edge of the plate (50) rearward to form a bight section (56) and successively upward to form a vertical section (58). The vertical section (58) is generally sandwiched between the front face (22) of the shield (18) and the front surface (38) of the housing (16). A horizontal extension (60) of the grounding device (14) vertically abuts against a supporting plate or a restriction tag (23) extending rearward from the front face (22) of the shield (18) for preventing the grounding device (14) from moving downward and leaving the connector (12).
