Optical connector

An optical connector comprising:

• an optical fiber;
• a ferrule assembly attached to a tip portion of the optical fiber;
• and
• a housing having an inner wall surface and a positioning part, the inner wall surface defining a space in which the ferrule assembly is to be accommodated, the positioning part defining an accommodation position of the ferrule assembly,
• wherein the positioning part is provided on the inner wall surface, and is defined by an inclined surface and a facing surface, the inclined surface being inclined with respect to a central axis of the tip portion of the optical fiber and being a surface with which a part of the ferrule assembly is to contact, the facing surface being positioned on a side opposite to the inclined surface with respect to the ferrule assembly and being a surface with which a part of the ferrule assembly is to contact,
• wherein the ferrule assembly includes
• a ferrule;
• and
• a sleeve member constituted by a sleeve and a flange, the sleeve having a front end surface and a rear end surface facing each other, the flange including edges each at least partly contacting the inclined surface and the facing surface of the positioning part,
• wherein the sleeve has a through hole connecting the front end surface and the rear end surface to each other and receiving a part of the ferrule from a side where the front end surface is provided before the tip portion of the optical fiber is attached thereto or after the tip portion of the optical fiber has been attached thereto, and
• wherein an outer peripheral portion of the flange includes:
• a first edge facing at least one of the inclined surface and the facing surface of the positioning part, and
• a second edge opposite the first edge,
• each of the first edge and the second edge includes a set including a deformation absorbing part and two contact portions, the deformation absorbing part being provided for suppressing deformation of the flange, the contact portions being disposed on both sides of the deformation absorbing part, and being configured to contact at least one of the inclined surface and the facing surface of the positioning part.
