Abstract
Abstract A receptacle for computer mother board connectors with a self-locking and electric shielding mechanism, which includes a rubber core (1) incorporated with a metal ring (2) and received in a metal casing (3). The rubber core (1) is unitarily made of rubber material through a shape molding process, and has a circular slot (13) on its front end, or top, for the insertion therein of the metal ring (2), two recessed holes (14) and two fastening holes (15) at both opposite sides for securing the metal ring and the metal casing to provide good electric shielding. The metal ring (2) has top clamping member (21) and inner projections (22) to match with corresponding convex portions (312) around the circumference of a hole (311) on the front wall (31) of the metal casing (3) permitting the clamping members and the inner projections to firmly retain the copper fastening tube of the plug which is inserted therein and permitting the clamping members to firmly contact the convex portions of the metal casing to form a grounded circuit. The metal ring also comprises a semi-circular hole (20) for the fastening therein of a retainer portion on the copper fastening tube of the matching plug so that the plug is firmly secured thereto.
