Claims

[Claims for Utility Model Registration] (1) There is an optical fiber holder that has an optical fiber storage and fixing part and an alignment part that maintains the alignment of the optical fiber, and the optical fiber holder is connected to the held optical fiber. In an optical connector that is movably housed in an outer case with a predetermined movement margin in the axial direction of the fiber, the alignment portion includes a V-shaped groove, a guide pin inserted into the groove, and a guide pin. A guide groove is formed on the outer periphery of the optical fiber holder on the side of the presser member, and is formed so that the end surface side of the connector is shallower. The optical connector is provided with a protruding piece on the corresponding inner surface of the outer case, the protruding piece being formed to protrude longer than the distance to the shallowest part of the guide groove and movable within the groove. (2) The optical connector according to claim 1, wherein the guide groove is formed as a two-step groove of a deep part and a shallow part. (3) The guide groove is formed as a tapered groove that gradually becomes shallower from the deep part.Claim 1 of Utility Model Registration
Optical connector described in section. (4) One or more contact surfaces of the V-shaped groove, the guide pin, or the holding member are formed of nitrided steel or hard ceramics, as set forth in claims 1 to 3 of the utility model registration claims. Optical connector described in any of the above.
