Claims

[Claims for Utility Model Registration] (1) A connection portion consisting of a ferrule with an optical connection surface formed at its tip attached to a holder with a circular outer surface and an optical fiber fixed to the ferrule, and a connection portion with an optical fiber having a circular inner surface. An optical connector plug comprising a plug body that receives, positions and holds the connection part on a circular inner surface, and the plug body has a fixed end on the front end side of the plug body and extends toward the rear end side. A locking piece having a spring property in the radial direction is provided, and the locking piece has a locking protrusion projecting radially inward from the circular inner surface at its free end, and the locking piece has a locking protrusion projecting radially inward from the circular inner surface. The optical connector plug has an inclined surface, and the holder includes a locking hole extending radially from the circular outer surface for receiving and locking the locking protrusion. (2) a connecting portion in which a ferrule with an optical connection surface formed at its tip is attached to a holder having a circular outer surface and an optical fiber is fixed to the ferrule; and a connecting portion having a circular inner surface and receiving the holder in the circular inner surface; An optical connector plug comprising a plug body that holds the ferrule and locks the ferrule against movement in the axial direction in a ferrule locking portion provided inside the circular inner surface, wherein the plug body is located at the tip of the plug body. A locking piece having a fixed end on the side, extending toward the rear end side, and having spring properties in the radial direction, the locking piece having a free end protruding radially inward from the circular inner surface. forming a protrusion and having an inclined surface on the inner rear end side of the locking protrusion;
The ferrule locking portion is provided with a notch having at least the circumferential width of the locking piece at the same circumferential position as the locking piece, and the holder is configured to receive and lock the locking protrusion. A locking hole is provided radially from the circular outer surface.
