Abstract
Abstract An electrical connector (25) includes a stamped receptacle contact (15) crimped to a wire (17) and fitted into a plastic housing (30) having an interior lance (39) operable to lock the contact within the housing to receive a tab terminal contact inserted within the receptacle contact. A locking part (40) of a thin, flat plastic configuration is inserted within the housing (15) from the front (31), latched therein in a first position allowing contact insertion from the rear (32) of said housing and in a second position wedging the interior lance against displacement to provide a double locking of said contact; projections (43, 44) on the part (40) cooperating with projections (49, 52) on the interior of the housing in latching of said part relative to said housing in the first and second positions.
