Abstract
Abstract A connector is disclosed for a fiber optic cable having one or more single optical fibers. A restraint member is fixedly attached to the strength member of the fiber optic cable. The restraint member is removably mounted in the rear section of a yoke while contacts terminated to the optical fibers are releasably mounted on the forward section of the yoke. The cable restraint member provides means so that the contacts may be positioned at equal distances from the end of the cable and the yoke permits the terminated fibers to be mounted in the connector without overstressing the fibers.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
82 words
A connector for one or more single optical fibers of a fiber optic cable having a strength member therein comprising: a support member having a forward section and a rear section; means on said forward section for releasably mounting a contact terminated to a single optical fiber; means for making fixed attachment to the strength member of a fiber optic cable; and means for removably mounting said attachment means on said rear section in a predetermined position relative to said forward section.
Claim 2
Dependent Claim
82 words
A connector for one or more single optical fibers of a fiber optic cable having a strength member therein comprising: a support member having a forward section and a rear section; means on said forward section for releasably mounting a contact terminated to a single optical fiber; means for making fixed attachment to the strength member of a fiber optic cable; and means for removably mounting said attachment means on said rear section in a predetermined position relative to said forward section.
Claim 3
Dependent Claim
51 words
A connector as set forth in claim 1 wherein said contact mounting means comprises: a groove in said forward section extending in the direction toward said rear section; and retaining means releasably connected to said forward section and having a groove therein registering with said first-mentioned groove defining a contact cavity.
Claim 4
Dependent Claim
60 words
A connector as set forth in claim 1 wherein: said contact mounting means includes a longitudinally extending contact cavity; and fiber vibration dampening means is mounted on said support member, said dampening means comprising an elastomeric spider behind said forward section, said spider having a longitudinally extending slot therein aligned with said cavity and adopted to receive said optical fiber.
Claim 5
Dependent Claim
21 words
A connector as set forth in claim 1 wherein: said attachment means comprises a sleeve having an outwardly extending flange thereon.
Claim 6
Dependent Claim
90 words
A connector as set forth in claim 4 wherein said mounting means for said attachment means comprises: a recess in said rear section extending in the direction toward said forward section and opening to one side of said rear section; a transversely extending slot in said rear section intersecting said recess and opening to said one side; and said recess slidably receiving said attachment means with each slot slidably receiving said flange, said flange and the sides of said slot restraining lengthwise movement of said attachment means in said yoke.
Claim 7
Dependent Claim
48 words
A connector as set forth in claim 1 wherein: said support member comprises a yoke including two longitudinally extending legs connecting said forward and rear sections, said legs being laterally spaced apart defining an open cavity therebetween in which optical fibers of the cable may be spread apart.
Claim 8
Dependent Claim
75 words
A connector as set forth in claim 6 wherein: said forward section has an upper surface and a lower surface; and said mounting means comprises at least one groove in each said upper and lower surface and extending toward said rear section, and a pair of retaining means each releasably mounted on one of said surfaces and having a groove therein registering with the groove on its corresponding forward section surface defining a contact cavity.
Claim 9
Dependent Claim
103 words
A connector as set forth in claim 7 wherein: said attachment means comprises a sleeve having an outwardly extending flange thereon; and said mounting means for said attachment means comprises a recess in said rear section extending in the direction toward said forward section and opening to one side of said rear section, a transversely extending slot in said rear section intersecting said recess and opening to said one side, said recess slidably receiving said attachment means with said slot slidably receiving said flange, and said flange and the sides of said slot restraining lengthwise movement of said attachment means in said yoke.
Claim 10
Dependent Claim
90 words
An optical fiber connector terminated to a fiber optic cable having a strength member and at least one optical fiber comprising: an elongated yoke having a forward section and a rear section connected by at least one longitudinally extending leg; a contact terminated to said optical fiber; means on said forward section for releasably mounting said contact thereon; means fixedly attached to said strength member of said cable; and means removably mounting said attachment means on said rear section in a longitudinally predetermined fixed position relative to said forward section.
Claim 11
Dependent Claim
90 words
An optical fiber connector terminated to a fiber optic cable having a strength member and at least one optical fiber comprising: an elongated yoke having a forward section and a rear section connected by at least one longitudinally extending leg; a contact terminated to said optical fiber; means on said forward section for releasably mounting said contact thereon; means fixedly attached to said strength member of said cable; and means removably mounting said attachment means on said rear section in a longitudinally predetermined fixed position relative to said forward section.
Claim 12
Dependent Claim
64 words
