Optical connector

An optical connector connected to an external optical adapter in a given connecting direction, the optical connector comprising:

• an inner housing, on a surface of which engaging parts for engaging the optical adapter are provided;
• a boot connected to the inner housing in the connecting direction on a side opposite the optical adapter;
• an outer housing configured to cover the engaging parts and mounted on the inner housing to be freely movable in the connecting direction;
• and
• a grip part extending from the outer housing in the connecting direction,
• wherein the engaging parts are exposed as the outer housing moves to the boot side in the connecting direction,
• the outer housing includes a first outer housing configured to cover the engaging parts, and a second outer housing provided on the boot side of the first outer housing and provided to be freely movable relative to the first outer housing in the connecting direction,
• when the second outer housing moves in a direction approaching the first outer housing, the second outer housing and the inner housing relatively move relative to the first outer housing, and thereby the engaging parts are exposed,
• when the second outer housing moves away from the first outer housing, the second outer housing and the first outer housing relatively move relative to the inner housing, and thereby the engaging parts are exposed,
• the second outer housing has cutout parts which are cut out in the connecting direction from an end part of the boot side and which a part of the boot enters,
• the second outer housing includes two notches provided on both sides of the cutout parts in a circumferential direction, the two notches being formed on a curved inner surface of the second outer housing,
• the grip part has a circular arc shape outer surface in cross section perpendicular to the connecting direction,
• the grip part includes two protrusion parts formed on the curved arc shape outer surface of the grip part,
• the two protrusion parts of the grip part engage with the two notches of the second outer housing by rotation about a longitudinal rotational axis of the grip part,
• the grip part covers a portion of the boot, and
• the grip part is freely mounted/demounted on/from the second outer housing by rotation about the longitudinal rotational axis of the grip part.
