摘要： PROBLEM TO BE SOLVED: To provide an optical connector capable of preventing reduction in positional accuracy of optical fiber holes, and capable of narrowing the connector area.
SOLUTION: This optical connector 11 of a fitting pin positioning type has a plurality of optical fiber holes 12 juxtaposed in a lateral row. Positioning two fitting holes 13 (or fitting pins) mutually exist on the opposite side by sandwiching a straight line L of connecting the centers of the optical fiber holes, and are arranged in point symmetry on the arrangement center P of the whole optical fiber holes on the straight line L. A lateral dimension (a width dimension W
1 ) of the optical connector can be reduced more than a laterally long flat optical connector having a fitting hole on both sides of an optical fiber hole row. A vertical dimension (a height dimension H) becomes large, and can be formed in a non-laterally long flat cross-sectional shape being not so much large in a vertical-lateral dimension difference. The optical connector is formed in a shape of hardly causing molding strain in resin molding, and reduction in the positional accuracy of the optical fiber hole can be prevented. The width dimension W
1 can be reduced, and when installed on a substrate, the connector area on the substrate can be narrowed.

摘要： PROBLEM TO BE SOLVED: To obtain an optical connector which does not have a problem that an engagement pin can not be inserted into a pin hole when positioned. SOLUTION: The optical connector 1 is provided with a circular cross-sectional engagement pin 15 and a rectangular cross-sectional projected part 16 which are projected toward a counterpart optical component on both sides interposing the optical input/output part 17 of the optical connector 1 as a positioning means of the counterpart optical component. When the optical connector 1 is installed on an optoelectric compound substrate on which an optical device is mounted, for example, the optical connector is positioned with resect to the optical device on the substrate by engaging the circular cross sectional engagement pin 15 with a circular hole provided on the substrate and the rectangular cross sectional projected part 16 with a rectangular cross-sectional groove provided on the substrate. In the case of a conventional structure for positioning by two engagement pins and pin holes, there may occur a problem that the engagement pins can not be inserted into the pin holes of the counterpart optical component due to poor accuracy of the pitch of the two pin holes, however the present optical connector has one position of engagement of the engagement pin and the pin hole and the other is the engagement between the rectangular cross-sectional projected part and the rectangular cross-sectional groove, and thus such a problem does not occur.
