Claims

[Scope of claim for utility model registration] (1) A ferrule fixed to the tip of an optical fiber inside a mail housing, and a flange provided halfway around the outer periphery of the ferrule abutting against a shoulder provided on the inner periphery of the mail housing. a guide tube that can abut against a positioning step provided on the outer periphery of the tip of the ferrule inside the socket end of the female housing to which the mail housing is detachably connected; In the optical connector, an optical transmitting/receiving unit is installed at the back of the guide tube, and a spring for bringing the unit into contact with the back shoulder of the guide tube, wherein the ferrule has a protrusion that protrudes from the tip surface of the optical fiber. An optical connector characterized in that a recess into which the protrusion fits is provided on the front surface of the optical transmitter/receiver unit. (2) The optical connector according to claim 1, which is a registered utility model, wherein a sleeve is placed over the outside of the tip of the ferrule, and the tip of the sleeve is made to protrude from the tip surface of the optical connector to form a protrusion. (3) The optical connector according to claim 2, wherein the sleeve is press-fitted onto the outside of the tip of the ferrule. (4) The optical connector according to claim 2, wherein the sleeve is bonded to the ferrule. (5) The optical connector according to claim 2, wherein the sleeve is threadedly engaged with the ferrule.
