Title: Optical connector
Inventor: SAITO KAZUTO
IPC: G02B6/36
Filed: 1989-01-13
Abstract: PURPOSE:To stably connect optical fibers with a low loss even in coupling without using a matching material by forming the coupling end face of the optical connector to the arc shape projecting in the direction orthogonal with the direction connecting the central positions of two guide pins. CONSTITUTION:The coupling end face 4 of the optical connector 1 is formed to the arc shape projecting in the direction orthogonal with the direction connecting the central positions of the guide pins to be inserted into two guide pin holes and is formed by aligning the vertex position X1-X1 of the projecting arc-shaped surface approximately to position of the optical fibers. The vertexes of the projecting arc-shaped surfaces of the coupling end faces, therefore, come into contact with each other at the time of coupling. As a result, the direct contact of the optical fibers is attained. The optical fibers are coupled by the direct contact of the optical fibers with each other without using the matching material in this way; in addition, the axial misalignment of the optical fibers by the inclination at the time of grinding the end faces and the increase of the loss by the angular misalignment are obviated.
