PURPOSE: To make an optical circuit connection for right-angled deflection with small-sized structure and to improve its precision by inserting united connector couplers into orthogonal through holes formed in the block of a connector body, and fixing a cover having a 45° slanting surface.
CONSTITUTION: The connector couplers 3 and 4 are inserted into the holes 1a and 1b of the connector body 1. The covers 2 are pressed in cut parts of the connector body 1. This cover 2 has the slanting surface 1a formed at the part corresponding to the intersection of the axes of the through holes 1a and 1b, and a reflecting member 2b such as a mirror is stuck on the slanting surface 2a. Consequently, a light signal transmitted through one optical fiber 16 is diffused and projected from an end surface 15 and made by the lens 5 of the connector coupler 3 into parallel luminous flux, which is deflected in optical path by the reflecting member 2b and made incident to the other optical fiber 17 for transmission through the lens 7 of the other connector coupler 4. Thus, the optical circuit connection is made with the small-sized structure and the precision is improved.
