Optical Connector

摘要

A ferrule 5 is composed of a capillary 51 and a flange 52 integrated with each other. The capillary 51 guides therethrough an optical fiber 3 protruding from a buffer tube 2 in an axial direction. The capillary 59 has a tip end 51a polished in a tilted convex face. The flange 52 is fixed to a rear end 51b of the capillary 51, and is formed with a key projection 52k engaged into a key recess 42 of an adaptor 4 to achieve the positioning of the ferrule 5 in a circumferential direction. A plug frame 6 has a front sleeve 6a for receiving therein the flange 52 of the ferrule 5, and a rear sleeve 6b extending axially from the front sleeve 6a for guiding the buffer tube 2. A clamp ring 8 is engaged around an outer periphery of the rear sleeve 6b of the plug frame 6, and is also engaged with a tip end of a cord tube 1 to fix the rear sleeve 6b and the cord tube 1 to each other. A coupling nut 9 is mounted around an outer periphery of the plug frame 6, and is screwed with the adaptor 4 so as to couple the plug frame 6 to the adaptor 4.
