Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
A strain-relief subassembly substantially for use with a cable for conducting radiation, said cable comprising: a core; a fibrous material surrounding said core; and an insulating material surrounding said fibrous material, the improvement comprising: said strain-relief subassembly being affixed to said cable and comprising: a first tubular member having an inside diameter substantially matching the outside diameter of said insulating material and fitted thereover, the outside diameter of said first tubular member having a roughened surface; a given length of said fibrous material extending beyond said insulating material, said given length of said fibrous material being folded back to engage said roughened surface; a second tubular member having an inside diameter formed to slide over said fibrous material and said first tubular member; holding means co-acting between said second tubular member, said fibrous material and said first tubular member to form said members into said subassembly; and engaging means formed on said second tubular member for cooperation with a surrounding housing, said engaging means comprising an upstanding flange.
Claim 2
Dependent Claim
168 words
A strain-relief subassembly substantially for use with a cable for conducting radiation, said cable comprising: a core; a fibrous material surrounding said core; and an insulating material surrounding said fibrous material, the improvement comprising: said strain-relief subassembly being affixed to said cable and comprising: a first tubular member having an inside diameter substantially matching the outside diameter of said insulating material and fitted thereover, the outside diameter of said first tubular member having a roughened surface; a given length of said fibrous material extending beyond said insulating material, said given length of said fibrous material being folded back to engage said roughened surface; a second tubular member having an inside diameter formed to slide over said fibrous material and said first tubular member; holding means co-acting between said second tubular member, said fibrous material and said first tubular member to form said members into said subassembly; and engaging means formed on said second tubular member for cooperation with a surrounding housing, said engaging means comprising an upstanding flange.
Claim 3
Dependent Claim
18 words
The strain-relief subassembly of claim 1 wherein said flange is adjacent an end of said second tubular member.
Claim 4
Dependent Claim
30 words
The strain-relief subassembly of claim 2 wherein said first tubular member is formed of a relatively non-compressible material and said second tubular member is formed of a relatively compressible material.
Claim 5
Dependent Claim
21 words
The strain-relief subassembly of claim 2 wherein said holding means comprises at least one crimp formed in said second tubular member.
Claim 6
Dependent Claim
20 words
The strain-relief subassembly of claim 4 wherein said first tubular member is steel and said second tubular member is brass.
Claim 7
Dependent Claim
23 words
The strain-relief assembly of claim 5 wherein said cable is a fiber optic cable and said core comprises at least one optical fiber.
