Claims

[Claims for Utility Model Registration] A ferrule having an optical connection surface formed at its tip is attached to a terminal housing having a circular outer surface, and an optical fiber is fixed to the ferrule, and a terminal having a circular inner surface. A connector housing having a circular inner surface fitted with a circular outer surface of the terminal housing to lock and receive the terminal housing at a predetermined axial position, and a stepped portion at the rear of the circular outer surface. The terminal housing is mounted between the small diameter portion of the terminal housing and the large diameter portion of the connector housing formed with a step portion at a position opposite to the step portion, with axial movement being restricted, and rearward movement of the terminal housing. an elastic locking ring having an axial groove that locks the small diameter portion, and a tapered surface formed at the tip of the elastic locking ring that is movably fitted in the small diameter portion in the axial direction, and the locking ring is pushed in from the rear. In the terminal positioning structure of the optical connector, the locking ring is provided with a pull-out ring that pushes the locking ring from the inner side to release the locking of the terminal housing, A locking portion having a pair of radial locking surfaces facing each other is provided, and a tapered surface facing the inner diameter side is formed at the rear end portion, and the connector housing is arranged on the inner surface of the large diameter portion. A terminal positioning structure for an optical connector, characterized in that a locking fitting part is provided that fits with the locking part, and the terminal housing is provided with a locking protrusion that fits with the split groove on the outer periphery of the small diameter part. .
