ABSTRACT:
A receptacle connector (10) includes an insulative housing (12) having a front mating portion (14) projecting from a front face (16) of a flange section (18) and having a mating face (20) in the front. A pair of rows of passageways (70) extend longitudinally within the connector (10) to receive a plurality of corresponding contacts (52, 60) therein, respectively. A central cavity (50) is positioned along the lateral center line and extends inwardly from the mating face (20) for receiving a blade of a complementary plug connector therein. A conductive shield (80) has a shroud adapted to surround the front mating portion (14) wherein the front portion of the shield (80) extends vertically an appropriate distance toward the cavity (50). The edge of the front portion of the shield (80) is serrated for designedly stimulating point effect of an electrical discharge and effectively preventing any high voltage electrostatic charge from invading the internality of the connector (10) and damaging the internal circuit connected to the connector (10).
