Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 239 words
A strain-relief, fiber optic component housing assembly comprising: an elongated, substantially tubular body having a longitudinal axis, said body having a first internal portion for mounting said component; a component mounted in said first portion; a second internal portion having an inner circumferential wall provided with a plurality of inwardly projecting, radially spaced ribs having a given longitudinal extent measured along said longitudinal axis; an optical fiber cable having a core comprising at least one optical fiber, a fibrous material surrounding said core and an insulating material surrounding said fibrous material positioned in said body in substantial alignment with said longitudinal axis; said optical fiber being operatively disposed within said component; and a strain-relief subassembly mounted within said second internal portion, said subassembly 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 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 engagement with said ribs.
Claim 2
Dependent Claim 239 words
A strain-relief, fiber optic component housing assembly comprising: an elongated, substantially tubular body having a longitudinal axis, said body having a first internal portion for mounting said component; a component mounted in said first portion; a second internal portion having an inner circumferential wall provided with a plurality of inwardly projecting, radially spaced ribs having a given longitudinal extent measured along said longitudinal axis; an optical fiber cable having a core comprising at least one optical fiber, a fibrous material surrounding said core and an insulating material surrounding said fibrous material positioned in said body in substantial alignment with said longitudinal axis; said optical fiber being operatively disposed within said component; and a strain-relief subassembly mounted within said second internal portion, said subassembly 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 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 engagement with said ribs.
Claim 3
Dependent Claim 23 words
The housing assembly of claim 1 wherein said engaging means comprises an upstanding flange having an outer circumferential edge which contacts said ribs.
Claim 4
Dependent Claim 26 words
The housing assembly of claim 2 wherein said ribs are formed from a relatively compressible material and said flange is formed from a relatively uncompressible material.
Claim 5
Dependent Claim 31 words
The housing assembly of claim 3 wherein said body is formed of substantially similar longitudinal halves and fastening means are provided on said body for joining said halves into a unit.
Claim 6
Dependent Claim 23 words
The housing assembly of claim 4 wherein said fastening means generate sufficient compression forces to cause said flange to bite into said ribs.
