Optical connector
An optical connector body is formed by an optically-transparent resin molding. The optical connector body includes an optical fiber insertion hole formed parallel to a board surface, a wall with which an optical fiber provided at a front of the optical fiber insertion hole contacts, and an internal reflection surface adjacent to and in front of the wall. The internal reflection surface is formed at a bottom surface of a bottomed hole opened from outside in the optical connector body.
1. An optical connector optically connecting respective set of optical fibers and optical elements by internal reflection, comprising:
an optical connector body, which is a resin molding, having a plurality of optical fiber insertion holes and a plurality of bottomed holes, each of the bottom surfaces of the bottomed holes functioning as an internal reflection surface, each of the internal reflection surfaces disposed in front of one of the optical fiber insertion holes;
wherein the bottomed holes are filled with air,
wherein the each of the internal reflection surfaces is integrally formed as a bottom surface of one of the bottomed holes,
wherein a resin between the optical fiber insertion holes and the internal reflection surfaces and the resin between the internal reflection surfaces and the optical elements are light transmissive,
wherein each of the plurality of bottomed holes is bored from an outer surface of the optical connector body and the plurality of bottomed holes are separate from each other,
wherein the respective set of optical fibers and the optical elements is optically connected by the respective internal reflection surface, and
wherein the internal reflection surfaces reflect light coming from the optical fiber insertion holes, and the light reflected by the internal reflection surfaces pass through the resin to the optical elements.
2. The optical connector according to claim 1 , wherein
a concave portion is provided in front of an exit of each of the optical fiber insertion holes, the concave portion opens toward an upper side of the optical connector body to be filled with an adhesive agent; an optical fiber contacting wall is provided in front of each of the optical fiber insertion holes in the concave portion,
wherein the internal reflection surfaces are provided in the optical connector body in front of and adjacent to the optical fiber contacting wall.
3. The optical connector according to claim 1 , wherein
an opening portion for introducing the optical fiber is provided behind each of the optical fiber insertion holes, and the opening portion opens to a rear side of the optical connector body; and
a hollow portion is provided behind each of the optical fiber insertion holes, and the hollow portion opens at the upper part of the optical connector body to be filled with an adhesive agent.
4. The optical connector according to claim 1 , wherein
the bottom surface of each of the bottomed holes is a flat surface.
5. The optical connector according to claim 1 , wherein
the bottom surface of each of the bottomed holes is a curved surface with a convex shape toward an opening side thereof.
