ABSTRACT:
To extend the service life of a latch of a plug housing and facilitate assembly and aligning operations of an optical connector. The optical connector includes a latch provided in a cantilever form on an external surface of the optical connector and deformable for attachment/detachment with respect to an adaptor, and an excessive deformation preventing unit that prevents excessive deformation of the latch. Furthermore, the optical connector comprises: a ferrule including a flange having a largest width portion having directionality in a circumferential direction and a conical portion continuous to the front of the largest width portion; and a housing including a cavity having a cylindrical portion through which the largest width portion can pass freely, a housing unit arranged in front of the cylindrical portion for housing the largest width portion, and an inclined surface that is arranged at a junction between the cylindrical portion and the housing unit and inclines inward in the radial direction from the cylindrical portion toward the housing unit, wherein the point of the ferrule is protruded from the point of the housing by a predetermined amount and held, in the state that the ferrule is inserted into the housing from a rear end of the cylindrical portion and the largest width portion of the flange is housed in the housing unit.
