Abstract
Abstract A connector for a fiber optic member (10) comprises a ferrule member (20) in which is positioned an insert (24) having rods (25) surrounding a section of an exposed end of the fiber optic member (10), the exposed end extending along a front bore (40, 42) of the ferrule member (20). A crimping ferrule (26) on the ferrule member (20) is controllably crimped thereon thereby moving the rods (25) into engagement with the fiber optic member (10) with no or minimum deformation to the fiber optic member (10) and securing the fiber optic member (10) in the ferrule member (20).

Claim 2
Dependent Claim
205 words
A connector for terminating a fiber optic member (10) of a fiber optic cable (FOC) of the type comprising a ferrule member (20) having a front section (30, 36) and a rear section (34), said front and rear sections having a profiled bore (38, 40, 42) extending therethrough, an insert (24) having a profiled bore (48) through which fiber optic member (10) extends and disposed within the profiled bore (38) of the rear section (34) of ferrule member (20), and a crimping ferrule (26) disposed along rear section (34) of ferrule member 20, characterised in that: said insert (24) has a cylindrical section (46) and said profiled bore (48) is in the form of a rod-receiving bore through said cylindrical section (46); rod members (25) are disposed in said rod-receiving bore (48) and are positioned therein to enable fiber optic member (10) to be inserted therealong with an end of fiber optic member (10) being positioned in said bore (40) adjacent a front surface of front section (30, 36) of ferrule member (20); said crimping ferrule (26) is to be controllably crimped onto said rear section (34) of ferrule member (20) thereby moving the rod members (25) into engagement with the fiber optic member (10).
Claim 3
Dependent Claim
99 words
A connector as set forth in claim 1 characterised in that the fiber optic cable (FOC) has strength members (14) and an outer jacket (16), a metal ring (22) positioned along said outer jacket (16) and over which said strength members (14) are positioned, said crimping ferrule (26) extending along said metal ring (22) and being controllably crimpable onto said metal ring (22) in the area of said strength members (14) to secure the strength members (14) between the crimping ferrule (26) and the metal ring (22) to provide strain relief between said connector and said fiber optic cable.
Claim 4
Dependent Claim
34 words
A connector as set forth in claim 1 characterised in that the end surface of said fiber optic member (10) is in the same plane as the front surface of said ferrule member (20).
Claim 5
Dependent Claim
46 words
A connector as set forth in claim 1 characterised in that said ferrule member (20) comprises a front cylindrical section (30), a central cylindrical section (32), a rear cylindrical section (34), and a conical section (36) extending between said front (30) and central (32) cylindrical sections.
Claim 6
