Strain relief for electrical connectors

A backshell adapter assembly with a strain relief function comprising:

• a clamp body having a ring portion defining a first axis and a pair of flat plate portions spaced apart and generally parallel to said first axis, each plate portion formed with a pivot hole, said ring portion formed with an angular groove;
• a pair of strain relief arms, each strain relief arm defining a first end and a second end, said first ends of said strain relief arms pivotably connected to said pivot holes on said pair of planes portions, said strain relief arms configured to extend beyond said plate portions, said strain relief arms defining a second axis and formed with notches for capturing a cable tie to thereby provide radial clamping of a cable disposed between said pair of strain relief arms;
• and
• a coupling nut for providing an interface to an electrical device, said coupling nut formed a ring adapted to be coupled to said annular groove on said clamp body and a second set of threads adapted to mate with the electrical device.

• and
• a coupling nut for providing interface to an electrical device, said coupling nut formed as a ring coupled to said annular groove on said clamp body and a set of threads adapted to mate with the electrical device;
• and
• a locking mechanism for locking at least one of said pair of strain relief arms relative to said clamp body, wherein said locking mechanism includes a pin formed on one of said strain relief arms and wherein said plate portions of said clamp body are provided with one or more apertures for receiving said pin to prevent rotation of said strain relief arms relative to said clamp body.
