ABSTRACT:
The problem of preventing breakage of the terminating connections of electrical wires (32) is solved by a strain relief device (12) adapted for use with an electrical connector (10) for terminating a multi-wire electrical cable (18). The strain relief device includes a pair of shell members (34) adapted for assembly to a terminating end of the electrical connector and for embracing the electrical cable. A first groove (36) is formed about the outside of the shell members when in assembly. A locking ring (38) is positionable in the first groove to hold the shell members in assembly on the electrical connector. A second groove (40) is formed on the inside of the assembled shell members. A clam;ing ring (42) is positionable in the second groove for clamping about the electrical cable when the shell members are held in assembly by the locking ring. A third groove (46) is formed on the inside of the assembled shell members for receiving an outwardly projecting flange (48) at the terminating end of the electrical connector to position the shell members in assembly on the connector. The connector and the shell members combine to define a fourth groove (49) on the outside of the assembly for receiving a sealing O-ring (26) for positioning within an opening (14) in an appropriate housing (16).
