Abstract
An optical connector includes a cylindrical front body formed with a center bore having a front cylindrical bore, a rear cylindrical bore and a tapered bore therebetween. A fiber holding unit made of a flexible material is separable into two parts, whose mating surfaces are formed with grooves for holding an optical fiber and at front and rear portions with spacers for partially preventing contact between the mating surfaces in the proximity of the spacers. The two assembled parts form cylindrical outer surfaces at front and rear ends and a tapered outer surface between the cylindrical outer surfaces. The two assembled parts with the optical fiber interposed therebetween are able to be fitted in the front body from its rear end. A rear body has a front end to be threadedly engaged in the rear end of the front body to urge forwardly the two assembled parts inserted into the front body, thereby clamping the optical fiber between the parts of the fiber holding unit by a wedge effect owing to the tapered surfaces of the front body and the fiber holding unit.
