A cable termination system for heavy duty cables having a threaded metallic or plastic shield includes only two members; a termination body and a termination nut, the former having internal threads mating with an internal thread shield of the cable and the latter having rounded internal threads mating with rounded external threads of the termination to clamp at least the outer braids of the cable between the external threads of the termination and the internal threads of the termination nut. The termination body is screwed onto the shield and provides an annular pocket to receive the end of the shield to protect the wires of the cable from burrs and sharp edges at the end of the shield. The internal threads of the termination have a different pitch from those of its external threads whereby the threads bind the termination nut and prevent it from becoming unscrewed from the cable. The termination nut is locked in place by snap rings and its end seats against an O-ring to isolate it from the environment while the other end of the nut engages a projection on the termination body to seat the outer covering of the cable between the two elements of the system.

[ What is claimed is:] [1.] A two-part, field repairable backshell adapter for assembly with a conduit including a hollow inner core having a helical thread formed on its outer surface, a metal shield over the inner core and a sheath over the shield comprisinga backshell adapter having a hollow conduit end fitting and a termination nut having internal threads,said conduit end fitting having at a first end including means for connecting the backshell adapter to another structure and having at a second end internal and external threads with an enlarged region separating said two ends,a hollow cylindrical lip extending axially from the enlarged region away from the first end,said hollow lip having an outer diameter such as to provide a snug fit within a core of a conduit when a conduit is disposed over said external threads and into contact with said enlarged region,said internal threads of the second end snuggly matable with the external threads of said core,said internal threads of said nut matable with said external threads of the second end of the conduit of the end fitting,said internal threads of said nut having a diameter to accept and snuggly capture a shield of a conduit between the two sets of threads.
