Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
An optical connector for use with an optical fiber cord having a jacketed optical fiber covered by a sheath with a tension member between the sheath and the jacketed optical fiber, comprising: a ferrule provided on a distal end of said optical fiber cord; an elongated stop ring also provided on said distal end of said optical fiber cord, and whose distal end position on said optical fiber cord is regulated by said ferrule; and a molded-on resin boot, which is molded onto distal ends of said tension member and said sheath, for integrally fixing the respective distal ends of both said tension member and said sheath, said resin boot being also molded onto a rear portion of said stop ring and onto a portion of said sheath and tension member, said resin boot not extending to the front end of said stop ring.
Claim 2
Dependent Claim
144 words
An optical connector for use with an optical fiber cord having a jacketed optical fiber covered by a sheath with a tension member between the sheath and the jacketed optical fiber, comprising: a ferrule provided on a distal end of said optical fiber cord; an elongated stop ring also provided on said distal end of said optical fiber cord, and whose distal end position on said optical fiber cord is regulated by said ferrule; and a molded-on resin boot, which is molded onto distal ends of said tension member and said sheath, for integrally fixing the respective distal ends of both said tension member and said sheath, said resin boot being also molded onto a rear portion of said stop ring and onto a portion of said sheath and tension member, said resin boot not extending to the front end of said stop ring.
Claim 3
Dependent Claim
25 words
An optical connector according to claim 1, wherein said resin boot is molded onto the distal end of said optical fiber cord by insert molding.
Claim 4
Dependent Claim
24 words
An optical connector according to claim 1, wherein said resin boot is molded over only about one-half the length of said elongated stop ring.
Claim 5
Dependent Claim
35 words
An optical connector according to claim 3, wherein said stop ring has projecting portions thereon, said resin boot being molded over said projecting portions to increase retention of said resin boot on said stop ring.
Claim 6
Dependent Claim
35 words
An optical connector according to claim 1, wherein said stop ring has projecting portions thereon, said resin boot being molded over said projecting portions to increase retention of said resin boot on said stop ring.
Claim 7
Dependent Claim
17 words
An optical connector according to claim 1, wherein said tension member comprises a plurality of elongated filaments.
Claim 8
Dependent Claim
25 words
An optical connector according to claim 6, wherein said filaments of said tension member are distributed around said stop ring inside said molded-on resin boot.
