Abstract: A connector includes an insulative housing (18), a plurality of contacts (23), a first shell (27), a second shell (38) and a grounding plate (44). The insulative housing (18) has a cubic body defining plural surfaces wherein a socket section (19) is disposed on one of such surfaces surrounded by an annular slot (20). A plurality of passageways (21) extend into the socket section (19). The first shell (27) and the second shell (38) commonly cover the most portions of the external surfaces of the body. The first shell (27) includes a pair of locking sections (35). A grounding plate (44) is adapted to be attached to the connector wherein the grounding plate (44) includes a pair of locking tags (49) for engagement with the corresponding locking sections (35) of the connector, respectively. The grounding plate (44) further includes an opening (47) in the front face (45) for allowing insertion of a plug into the socket (19).
