Abstract
Abstract An optical fiber connector in which the fiber terminations are cylindrical but have a protruding circumferential triangular cross-sectional ridge. Two terminations are aligned in end-to-end butting relationship in a hole through a resilient receptacle which has grooves corresponding to the ridges but at a slightly closer separation so that they urge the terminations into contact with each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
An optical fiber demountable connector comprising: a resilient coupling receptacle having a hole therethrough; a pair of optical fibers held butted together in end-to-end relationship in said hole; the butting end of each said fiber being secured inside a terminating collar and terminating at one end thereof with the fiber aligned with the collar axis; each said collar having an interference fit in the receptacle hole and including a rear-facing bevel between one portion and a portion of enlarged diameter nearer the free end of the collar; and the receptable hole having generally complementary bevels at a spacing such that when the bevels are engaged by the collar bevels they act to urge the free ends of the collars into contact with each other.
Claim 2
Dependent Claim
124 words
An optical fiber demountable connector comprising: a resilient coupling receptacle having a hole therethrough; a pair of optical fibers held butted together in end-to-end relationship in said hole; the butting end of each said fiber being secured inside a terminating collar and terminating at one end thereof with the fiber aligned with the collar axis; each said collar having an interference fit in the receptacle hole and including a rear-facing bevel between one portion and a portion of enlarged diameter nearer the free end of the collar; and the receptable hole having generally complementary bevels at a spacing such that when the bevels are engaged by the collar bevels they act to urge the free ends of the collars into contact with each other.
Claim 3
Dependent Claim
28 words
A connector as set forth in claim 1 wherein: each collar has a cylindrical surface interrupted by a circumferential ridge intermediate its ends, said ridge including said bevel.
Claim 4
Dependent Claim
15 words
A connector as set forth in claim 2 wherein: said ridge is triangular in cross-section.
Claim 5
Dependent Claim
26 words
A connector as set forth in claim 1 wherein: said collars are made of resin and terminate at their free ends with watch pierced bearing jewels.
Claim 6
Dependent Claim
77 words
An optical fiber demountable connector comprising: a resilient coupling receptacle having a hole therethrough; a pair of optical fibers each terminated by a collar, said collars having mating end faces facing each other in said hole; each said collar having a rear-facing bevel; and said receptacle hole having generally complementary bevels at a spacing such that when said hole bevels are engaged by said collar bevels they cooperate to urge said mating end faces into abutting engagement.
Claim 7
Dependent Claim
77 words
An optical fiber demountable connector comprising: a resilient coupling receptacle having a hole therethrough; a pair of optical fibers each terminated by a collar, said collars having mating end faces facing each other in said hole; each said collar having a rear-facing bevel; and said receptacle hole having generally complementary bevels at a spacing such that when said hole bevels are engaged by said collar bevels they cooperate to urge said mating end faces into abutting engagement.
