A request for registration of a utility model, characterized in that the distal end surface of the ferrule is finished at an inclined angle with respect to a plane perpendicular to the optical axis of the optical fiber, and the positioning pin is located on the central axis of the inclined surface of the ferrule. The optical fiber connector according to item 1.

Claims (1)

[Claims for Utility Model Registration] The device comprises a pair of plugs and an alignment sleeve member that removably fixes the plugs with their tips abutting each other, and the plug has at least two holes on its outer periphery.
a ferrule having a collar with two notched grooves, in which an optical fiber is disposed and fixed; an inner circumferential surface having at least two protrusions that engage with the notched grooves; an outer circumferential surface that engages with the alignment sleeve; a cylindrical frame that accommodates the ferrule; a stopper screwed onto the rear end of the frame; a spring interposed between the stopper and the collar of the ferrule; An optical fiber connector comprising a cap nut attached to the outside of the frame and screwable to the alignment sleeve member. 2. An optical fiber connector, wherein the tip end surface of the ferrule is finished at an angle of inclination with respect to a surface perpendicular to the optical axis of the optical fiber, and the positioning key is located on the central axis of the inclined surface of the ferrule.
