Abstract
Abstract A straight-line backshell assembly providing strain relief and shield grounding for an electrical cable connector is separable between the tubular housing section which carries the cable gripping means and the rotatable-ring coupling section which is adapted to screw on the rear of the connector. For an angular backshell, an elbow section of the desired angle and an identical rotatable-ring coupling section are added to the straight-line backshell assembly.

Claim 1
Independent Claim
202 words
An angular back shell assembly for providing strain relief in attachment of a cable to an electrical connector, comprising in connected sequence and in combination, a first coupling section, a tubular elbow member having different internal threads at its two ends, an adapter having two differently threaded portions, a second coupling section, and a straight tubular body having internal threads in at least one end thereof, said first and second coupling sections being interchangeable, each consisting of a ring externally threaded to fit a mating thread either in one end of said tubular elbow member or in said one end of said tubular body, and a coupling nut rotatably carried on said ring and internally threaded to fit either an electrical connector or one threaded portion of said adapter, said first coupling section threadedly attached to one end of said elbow and said second coupling section threadedly attached to one of said threaded portions on said adapter and to said internal threads on said straight tubular body, the other threaded portion of said adapter mating with the thread in the other end of said tubular elbow member, and said tubular body carrying strain relief means adapted for gripping a cable extended therethrough.
Claim 2
Dependent Claim
202 words
An angular back shell assembly for providing strain relief in attachment of a cable to an electrical connector, comprising in connected sequence and in combination, a first coupling section, a tubular elbow member having different internal threads at its two ends, an adapter having two differently threaded portions, a second coupling section, and a straight tubular body having internal threads in at least one end thereof, said first and second coupling sections being interchangeable, each consisting of a ring externally threaded to fit a mating thread either in one end of said tubular elbow member or in said one end of said tubular body, and a coupling nut rotatably carried on said ring and internally threaded to fit either an electrical connector or one threaded portion of said adapter, said first coupling section threadedly attached to one end of said elbow and said second coupling section threadedly attached to one of said threaded portions on said adapter and to said internal threads on said straight tubular body, the other threaded portion of said adapter mating with the thread in the other end of said tubular elbow member, and said tubular body carrying strain relief means adapted for gripping a cable extended therethrough.
Claim 3
