Abstract
Abstract A fiber optic connector having a slotted housing has an interior ribbed member projecting through the housing slot. A dust cap is rotatably fixed to the housing to prevent rotation while a tool slides a locking member over the housing slot to force the ribbed member inwards, centering optical fibers. A portion of the connector is factory built so that users need use no epoxies or curing devices.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A fiber optic connector, comprising: (a) a longitudinally extending housing having an inner surface delimiting a first space, said housing having an outer surface and a first slot extending from the outer surface to the inner surface; (b) a first body carried by the housing within the first space, the first body having a first rib extending through the first slot; (c) a locking member carried on the outer surface of the housing adapted to slide in the longitudinal direction of the housing from a first position not covering the slot to a second position covering the slot; and, (d) securing means for holding the locking member in the second position to force the first rib radially inward with respect to the housing.
Claim 2
Dependent Claim
123 words
A fiber optic connector, comprising: (a) a longitudinally extending housing having an inner surface delimiting a first space, said housing having an outer surface and a first slot extending from the outer surface to the inner surface; (b) a first body carried by the housing within the first space, the first body having a first rib extending through the first slot; (c) a locking member carried on the outer surface of the housing adapted to slide in the longitudinal direction of the housing from a first position not covering the slot to a second position covering the slot; and, (d) securing means for holding the locking member in the second position to force the first rib radially inward with respect to the housing.
Claim 3
Dependent Claim
38 words
A fiber optic connector as recited in claim 1 wherein the locking member abuts the first rib when the locking member is in the second position to force the first rib radially inward with respect to the housing.
Claim 4
Dependent Claim
18 words
A fiber optic connector as recited in claim 1, further comprising an optical fiber within the first space.
Claim 5
Dependent Claim
18 words
A fiber optic connector as recited in claim 3, further comprising a crimping tube carried outside the housing.
Claim 6
Dependent Claim
31 words
A fiber optic connector as recited in claim 3, further comprising a ferrule held by the housing and means for preventing rotation of the ferrule during movement of the sliding means.
Claim 7
Dependent Claim
38 words
A fiber optic connector as recited in claim 3, further comprising a second rib mounted to the exterior of the housing and a slotted end member over the housing such that the second rib engages the slotted member.
Claim 8
Dependent Claim
52 words
A fiber optic connector as recited in claim 6, further comprising a tool for applying compressive longitudinal force on the slotted end member and the locking member, the tool and the slotted end member having mating exterior surfaces preventing rotation of the slotted end member while compression is applied by the tool.
Claim 9
Dependent Claim
38 words
A fiber optic connector as recited in claim 6, further comprising a tool holding the slotted end member in a fixed position with respect to rotation and urging the sliding member from the first to the second position.
