Claims

[Claims for Utility Model Registration] 1. An optical fiber insertion hole 9 into which the single-core optical fibers 1A, 1B are inserted, and a fitting pin insertion hole 6 parallel to the insertion hole; By inserting a fitting pin 7 into the insertion hole, the optical fiber connecting ferrules 8A are connected to each other with the axes of the insertion holes aligned, and the tips of the optical fibers in the optical fiber insertion holes are brought into close contact with each other. 8B, on the surfaces of the tips of the ferrules that are to abut against each other, there is a protrusion 1 having a square shape centered on the axis when viewed from the axis of the optical fiber insertion hole.
An optical fiber connection ferrule characterized in that a 0 is provided. 2 The optical fiber insertion hole 9 is provided in the protrusion 10.
The optical fiber connection ferrule according to claim 1, wherein the optical fiber connection ferrule is formed into a spherical surface having one of its radii along the axis of the ferrule.
