ABSTRACT:
An improved insulation displacing electrical contact (14) and method of making the contact (14) is disclosed. The contact (14) comprises a holder (16), a retention sleeve (18) and brush wires (22). The holder includes a body portion (20) having an axial passage (24) extending therethrough and a head portion (28) connected to the body portion (20) by a curved interconnecting neck portion (30). The head portion (28) includes a pair of angled legs (38, 40) and an interconnecting bent portion (42). A slot (32) extends through the bent portion (42) and through the legs (38, 40). Each leg has a pair of opposing stripping surfaces (48, 50) for stripping insulation (13) from a wire cable (12) inserted through the slot (32) and each leg has a pair of opposing gripping surfaces (52, 54) for holding the stripped wire cable (12) in the slot (32). As a result, a stripping position and a gripping position are formed at each leg, the two stripping positions being spaced apart a smaller distance than the distance between the two gripping positions. The brush wires (22) are axially aligned and axially mounted within the passage (24) of the body portion (20). The retention sleeve (18) including a pair of radially deflectable retaining ears (70, 72) is telescopically positioned over the body portion (20) and crimped thereto to provide a means for retaining the assembled contact (14) within a housing passage (76).
