Claims

[Scope of utility model registration request]

An optical connector plug used for an optical fiber cord formed by covering an optical fiber core with Keppler and a sheath, the plug comprising: a ferrule that is fitted onto the tip of an exposed portion of the optical fiber core exposed at the tip of the optical fiber cord; The ferrule is attached to the front end and loosely fits around the outer periphery of the exposed portion of the optical fiber core, and the outer periphery of the part slightly away from the rear end is formed into a male threaded part having a larger diameter than the outer peripheral surface of the rear end. a plug body, and the side portion fits onto the outer periphery of the rear end of the plug body, and a portion of the optical fiber cord extending from the Keppler sheath end surface is inserted between the fitting surfaces, and a rear end side portion thereof. a cylindrical cap that fits externally on the sheath and has a secured flange on the outer periphery of the front end; and a cylindrical cap that fits externally on the cap and has an engaging flange on the inner periphery that engages with the engaging flange; and a cap nut which is screwed onto the male thread part number and presses the front end surface of the cap against the step surface of the side edge of the male thread part of the plug joint.
