Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
118 words
A connector for optical fibers, said connector comprising: a body having opposed aligned sockets leading to an interconnecting bore, each socket having a tapered seat adjacent the bore; a pair of terminals, each terminal comprising a pair of elongated channel members having complementary mating surfaces, each channel member being split into fingers at one end, said fingers terminating in jaws adapted to contact and align the stripped end of an optical fiber otherwise extending through but not in contact with said members, said jaws having tapered outer surfaces, there being a terminal in each socket; and inter-engaging latch means on said terminals and the body for holding terminals in said sockets with the tapered surfaces engaging said seats.
Claim 2
Dependent Claim
118 words
A connector for optical fibers, said connector comprising: a body having opposed aligned sockets leading to an interconnecting bore, each socket having a tapered seat adjacent the bore; a pair of terminals, each terminal comprising a pair of elongated channel members having complementary mating surfaces, each channel member being split into fingers at one end, said fingers terminating in jaws adapted to contact and align the stripped end of an optical fiber otherwise extending through but not in contact with said members, said jaws having tapered outer surfaces, there being a terminal in each socket; and inter-engaging latch means on said terminals and the body for holding terminals in said sockets with the tapered surfaces engaging said seats.
Claim 3
Dependent Claim
28 words
The connector of claim 1, each socket having a counterbore between its conical seat and said bore, the fingers on each terminal having squared ends within a counterbore.
Claim 4
Dependent Claim
39 words
The connector of claim 1, said jaws having segments of increased radial extent adjacent said tapered outer surfaces, said segments presenting an interrupted cylindrical surface adapted to slidably engage the body within a socket as each terminal is inserted.
Claim 5
Dependent Claim
22 words
The connector of claim 1 wherein the ends of said tapered seat of each socket are opposedly aligned within an alignment collar.
