Claims

[Scope of utility model registration request]

(1) a first support body to which a first optical fiber that emits light from one end is fixed; a first lens that is fixed to the first support body and converts the light into parallel light; a second lens that converges the parallel light; a second support to which the second lens is fixed and a second optical fiber which receives the emitted light of the second lens at one end is fixed; , three positioning pins that determine the mutual positions of the first and second supports, three positioning pieces corresponding to the positioning pins, and both supports with the positioning pins pressed against the positioning pieces. means for joining the bodies, the axis of the positioning pin is parallel to the optical axis of both the lenses, and the positioning pin and the positioning piece are each fixed to either one of the supports. An optical fiber connector characterized by:

(2) Optical fiber according to claim 1 of the utility model registration claim
1. An optical fiber connector comprising a mechanism for adjusting the length of the positioning pin.

(3) In the optical fiber connector according to claim 1 or 2 of the utility model registration claim, the coupling means includes an elastic body that presses one of the two supports toward the other. Features of optical fiber connectors.
