Abstract

An electrical connector assembly (2) comprises mating blade and receptacle connectors (4,6), each having a plurality contacts disposed in an insulated housing (8, 72). The blade connector (4) includes power or signal blade contacts having contact blades (70) and a ground blade contact having a contact blade (42). A tab (64) projects in the mating direction from the forward edge (66) of the ground contact blade (42). Each receptacle contact (96) has contact springs (108, 114) having contact surfaces (110, 120). One receptacle contact (96) is a ground contact, and the other receptacle contacts (96) are power or signal contacts. When the connectors (4, 6) are mated, the tab (64) first engages the ground receptacle contact (96) thus making the,ground circuit of the connector assembly (2). The forward edges (66, 71) of the contact blades (42, 70) then pass substantially simultaneously between the contact surfaces (110, 120) of the respective receptacle contacts (96) and the tab (64) is received in an opening (124) defined between the contact springs (108,114) of the ground receptacle contact (96).
