摘要： PURPOSE:To facilitate manufacture and reduce manufacturing man-hour by coating the tip face of the ferrule with adhesive, inserting it in a lens holder, and curing the adhesive under a state where the tip face of the ferrule is in a pressurized contact with one end face of the rod lens. CONSTITUTION:The rod lens 2 is fixed and retained inside the lens holder 5 beforehand, and the tip face 4a of the ferrule 4 loaded with optical fiber 3 terminal is coated with adhesive 7 and inserted inside the lens holder 5, in a state where the ferrule end face 4a is in a pressurized contact with the rod lens 2 end face until the adhesive 7 is hardened. Therefore, since positioning of the rod lens and the optical fiber 3 is carried out by abutting the rod lens 2 end face 4a to the ferrule end face 4a, there is no necessity for special adjustment procedure, and the manufacture is greatly facilitated. Thus, the manufacture can be facilitated and the manufacturing man-hour can be reduced.

摘要： PURPOSE:To shorten the time required for fixing and executing an optical fiber to a ferrule by deforming a fiber insertion hole to bring the internal peripheral surface of the fiber insertion hole into tight contact with the optical fiber inserted into the fiber insertion hole. CONSTITUTION:Pin press-fitting holes 14 are provided in parallel with the fiber insertion hole 12 near the fiber insertion hole 12 of the ferrule and pins 16 of the diameter slightly larger than the diameter of the pin press-fitting holes 14 are press-fitted into the pin press-fitting holes 14, by which the fiber insertion hole 12 is deformed and the inner peripheral surface of the fiber insertion hole 12 is brought into tight contact with the optical fiber 18 inserted into the fiber insertion hole 12. The optical fiber 18 is, therefore, fixed into the fiber insertion hole 12 by the friction force generated by the tight adhesive force and the need for adhesives is eliminated. There is no need for the time required for fixing by the adhesives. The time required for fixing the optical fiber 18 to the ferrule is shortened in this way.

摘要： PURPOSE:To easily connect a connector to an optical fiber by assembling a ferrule, a stopper member, a spring, and a connector main body as a subassembly, and inserting an optical fiber into the ferrule from behind and adhering it. CONSTITUTION:The connector main body 34 has a small-diameter fitting hole 36 where the base-end small-diameter part 18 of the ferrule 12 is fitted at one end side, a large-diameter fitting hole 38 where the intermediate large-diameter part 16 of the ferrule 12 is fitted at the intermediate part, and an edge hole 40 where the screw part 30 of the stopper member 24 is engaged threadably at the other end side. The coil spring 44 is interposed between the intermediate large-diameter part 16 of the ferrule 12 and the step part 42 of the connector main body 34 and the connector main body 34 is engaged threadably with the stopper member 24 so that the ferrule 12 is put inside, thereby forming the subassembly. At this time, the base end small-diameter part 18 of the ferrule 12 projects from one end side of the connector main body 34. When the optical fiber is fitted to the ferrule, it is fitted to the optical connected formed as the subassembly, so the operability of the connection of the optical fiber is improved greatly.
