Patent ID: 8408816

Claim:
An optical connector mounted on an optical component, the optical connector comprising: a connection end surface; a pair of fitting projecting portions which is provided on the connection end surface, and in which first fitting projection portion is a circular cross-sectional fitting pin and second fitting projection portion is a rectangular cross-sectional projecting portion; and an optical input and output portion which is provided on the connection end surface, and between the circular cross-sectional fitting pin and the rectangular cross-sectional projecting portion, the circular cross-sectional fitting pin and the rectangular cross-sectional projecting portion being arranged along and optical fiber introducing direction, the optical component comprising: a pair of fitting reception portions in which first fitting reception portion a circular hole to which the circular cross-sectional fitting pin is fitted and a rectangular cross-sectional groove to which the rectangular cross-sectional projecting portion is fitted; an optical element which is provided between the circular hole and the rectangular cross-sectional groove, the circular hole and the rectangular cross-sectional groove being arranged along the optical fiber introducing direction, wherein the optical connector is assembled to a front end of an optical fiber, the optical fiber having an optical axis direction different from that of the optical element, the optical connector converts an optical path from the optical fiber toward an optical element, and the optical connector is positioned to the optical element by the fitting projecting portions fitting to the fitting reception portions.
