A strain release clamp assembly consisting of a backshell component or female component member and a compression ring or male component member. The female component member is a generally cylindrical component having a plurality of radially directed bearing access ports therethrough for a screw-type adjusting member, a ball bearing, and an intermediate biasing means. The inside surface of the female member includes a concentric groove with an access channel to the outside surface for containing one side portion of a locking wire inserted through the access channel. The male member includes on the outside surface with a matching concentric groove for receiving the opposite side portion of the locking wire and includes a plurality of spaced apart ball bearing depressions. The female component member receives the male component member and is locked thereto by the locking wire. Unintentional relative rotation between the female component member and the male component is prevented by the ball bearings held in the depressions.

DETAILED DESCRIPTION A strain relief clamp assembly comprising a cylindrical internally threaded coupler or female connecting member which is attached to an elbow wire clamping device by a wire locking device which fits into grooves or slots on both the female and male connecting members.
The wire is inserted into these slots after the male and female connecting members are mated and aligned with each other.
The wire is passed through a hole having an entrance in the outside of the female coupling member that leads into the grooves.
This wire locking mechanism allows the backshell component female coupling nut member to be screwed onto an electrical connector without rotating the elbow or male component member.
Each of the grooves are sized and shaped to contain a side portion of the locking wire that prevents relative axial movement of the strain relief clamp assembly sometimes referred herein as the accessory assembly or electrical connector accessory assembly.
The strain relief clamp assembly is assembled and locked together by a wire and is prevented from unintentional rotation by biased ball bearings means.
The accessory assembly includes a first main part is a backshell component or female component member and the second main part is a compression ring or male component member.
The female component member is a generally cylindrical coupling nut having connecting threads at one end and interconnecting means at the other end.
The interconnecting means at the other end includes a plurality of radially directed bearing access ports therethrough.
Each port includes an outside screw adjusting member, mating threads in the port, biasing member below the screw adjusting member, and a ball bearing partially positioned in the port below the biasing member.
The compression ring or male member is connected in the female member as set forth above.
The male member includes on the outside surface a concentric groove that is positionable beneath the concentric groove in the female member.
The concentric groove in the outside surface of the male member receives the opposite side portion of the locking wire
