Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A fiberoptic cable with integral strain-relieved termination comprising: a. an extended bundle of optical fibers, bonded and finished at at least one end; b. one tube of elastomeric material covering said bundle and terminating short of said one end; c. a second tube of elastomeric material having a length in the range of 4 to 16 centimeters covering and integrally bonded to said one tube, said second tube terminating proximate said one end but short of said one tube; d. a cylindrical sleeve overlapping and adhesively bonded to said one tube and a short portion of said second tube; and, e. a rigid housing mechanically secured to and enclosing the full length of said sleeve and providing an optical aperture at said one end.
Claim 2
Dependent Claim
124 words
A fiberoptic cable with integral strain-relieved termination comprising: a. an extended bundle of optical fibers, bonded and finished at at least one end; b. one tube of elastomeric material covering said bundle and terminating short of said one end; c. a second tube of elastomeric material having a length in the range of 4 to 16 centimeters covering and integrally bonded to said one tube, said second tube terminating proximate said one end but short of said one tube; d. a cylindrical sleeve overlapping and adhesively bonded to said one tube and a short portion of said second tube; and, e. a rigid housing mechanically secured to and enclosing the full length of said sleeve and providing an optical aperture at said one end.
Claim 3
Dependent Claim
13 words
A fiberoptic cable according to claim 1 wherein said cylindrical sleeve is metallic.
Claim 4
Dependent Claim
30 words
A fiberoptic cable according to claim 2 wherein said cylindrical sleeve is stainless steel and is adhesively bonded to said one tube and said second tube by an epoxy resin.
Claim 5
Dependent Claim
27 words
A fiberoptic cable according to claim 1 wherein said second tube tapers from a maximum thickness adjacent said housing to a minimum thickness away from said housing.
Claim 6
Dependent Claim
29 words
A fiberoptic cable according to claim 4 wherein said second tube commences prior to said housing and terminates inside said housing short of the termination of said one tube.
Claim 7
Dependent Claim
23 words
A fiberoptic cable according to claim 5 wherein said sleeve commences with said housing and terminates beyond the termination of said one tube.
Claim 8
Dependent Claim
19 words
A fiberoptic cable according to claim 1 wherein said housing is mechanically secured to said sleeve by a press-fit.
