Abstract

As a cylindrical optical connector, an optical connector includes a pushing member that has a structure that is suitable for holding a coil spring in the optical connector, and that has a structure that, even if clockwise or counterclockwise twisting occurs with respect to an axial direction of the optical connector, properly restricts rotation of the pushing member and, thus, does not allow disengagement of the pushing member caused by an applied force resulting from the rotation of the pushing member to easily occur.

First claim

What is claimed is:

1. An optical connector comprising:
a ferrule that is connected to an optical fiber cable;
a fitting section that holds a front end portion of the ferrule therein and that is fitted to a mating optical connector;
an elastic member that is disposed at a back end portion of the ferrule;
an accommodation section that accommodates the ferrule and the elastic member therein; and
a pushing member that pushes the elastic member into the accommodation section and that is mounted in the accommodation section,
wherein the accommodation section includes a retaining section that protrudes from an inner wall of the accommodation section,
wherein the pushing member includes a lock section for receiving the retaining section,
wherein, when the pushing member is mounted in the accommodation section, the lock section is fixed by being pushed against the retaining section by an elastic force of the elastic member accommodated in the accommodation section,
wherein the pushing member includes a cutaway section that is formed by cutting out a portion of a side wall of the pushing member, and
wherein the cutaway section is formed such that, when mounting the pushing member in the accommodation section, the retaining section and the cutaway section are aligned and the pushing member is pushed into the accommodation section to pass the retaining section through the cutaway section.

2. The optical connector according to claim 1 , wherein the pushing member includes a lock protrusion that protrudes from an edge of the lock section facing the cutaway section,
wherein the lock protrusion is formed so as to, when mounting the pushing member in the accommodation section, traverse the retaining section as a result of the retaining section passing through the cutaway section and the pushing member rotating from a state in which the pushing member contacts a surface in the accommodation section, and
wherein, after the pushing member is mounted in the accommodation section, the lock protrusion comes into contact with the retaining section to restrict rotation of the pushing member.

3. The optical connector according to claim 1 , wherein the pushing member includes a concave-shaped jig receiver that, when mounting the pushing member in an end portion of the accommodation section, receives a jig for rotating the pushing member.

4. The optical connector according to claim 1 , wherein the pushing member includes a recessed section in a surface of the pushing member that contacts the elastic member, and
wherein the recessed section holds an end portion of the elastic member and restricts displacement of the elastic member.

5. An optical connector comprising:
a ferrule that is connected to an optical fiber cable;
a fitting section that holds a front end portion of the ferrule therein and that is fitted to a mating optical connector;
an elastic member that is disposed at a back end portion of the ferrule;
an accommodation section that accommodates the ferrule and the elastic member therein; and
a pushing member that pushes the elastic member into the accommodation section and that is mounted in the accommodation section,
wherein the accommodation section includes a retaining section that protrudes from an inner wall of the accommodation section,
wherein the pushing member includes a lock section for receiving the retaining section,
wherein, when the pushing member is mounted in the accommodation section, the lock section is fixed by being pushed against the retaining section by an elastic force of the elastic member accommodated in the accommodation section, and
wherein the pushing member includes a concave-shaped jig receiver that, when mounting the pushing member in an end portion of the accommodation section, receives a jig for rotating the pushing member.

6. An optical connector comprising:
a ferrule that is connected to an optical fiber cable;
a fitting section that holds a front end portion of the ferrule therein and that is fitted to a mating optical connector;
an elastic member that is disposed at a back end portion of the ferrule;
an accommodation section that accommodates the ferrule and the elastic member therein; and
a pushing member that pushes the elastic member into the accommodation section and that is mounted in the accommodation section,
wherein the accommodation section includes a retaining section that protrudes from an inner wall of the accommodation section,
wherein the pushing member includes a lock section for receiving the retaining section,
wherein, when the pushing member is mounted in the accommodation section, the lock section is fixed by being pushed against the retaining section by an elastic force of the elastic member accommodated in the accommodation section, and
wherein the pushing member includes a recessed section in a surface of the pushing member that contacts the elastic member, and
wherein the recessed section holds an end portion of the elastic member and restricts displacement of the elastic member.
