Abstract

An optical connector includes optical fibers, a ferrule, and a pitch fixing member. The optical fibers have bare parts where coating parts have been stripped off. The ferrule has insertion holes, and the bare parts are inserted into the insertion holes. The pitch fixing member is inserted into the ferrule and has fixing parts that fix a pitch of the coating parts of the optical fibers to a pitch of the insertion holes.

First claim

What is claimed is:

1. An optical connector comprising:
optical fibers having bare parts where coating parts have been stripped off;
a ferrule having insertion holes into which the bare parts are inserted; and
a pitch fixing member that is inserted into the ferrule and that has fixing parts that fix a pitch of the coating parts of the optical fibers to a pitch of the insertion holes, wherein
the pitch fixing member has a step, and
inlet parts of the fixing parts are formed on the step.

2. The optical connector according to claim 1 , wherein
the insertion holes are disposed in rows, and
the fixing parts correspond to the insertion holes.

3. The optical connector according to claim 1 , further comprising:
a boot that has a mounting part that mounts the pitch fixing member and attaches to the ferrule together with the pitch fixing member.

4. The optical connector according to claim 1 , wherein each of the fixing parts has a hole part.

5. The optical connector according to claim 1 , wherein the fixing parts are formed by a plurality of groove parts and a top wall part that restricts disengagement of the coating parts from the plurality of groove parts.

6. The optical connector according to claim 5 , wherein the plurality of groove parts are formed by V-shaped grooves.

7. The optical connector according to claim 6 , wherein the top wall part is formed by a plurality of V-shaped grooves.

8. The optical connector according to claim 1 , wherein the coating parts of the optical fibers are supported by the fixing parts at four points.
