Patent ID: 8727641

Claim:
An optical connector, comprising: a substrate; a photoelectric element positioned on the substrate; a case comprising: a positioning element comprising: a base comprising a first surface and a second surface opposite to the first surface, the base defining a through hole running through the first surface and the second surface, the base being positioned on the substrate, the first surface contacting the substrate, the photoelectric element being received in the through hole and positioned at a pre-designed positioned in relative to the positioning element; and a positioning structure formed on the second surface; a transparent lens element comprising: a main body comprising an incident surface, an emitting surface, and a reflecting surface, light entering into the incident surface being directed to the emitting surface via total internal reflection on the reflecting surface; a locating structure structurally matching with the positioning structure, the lens element being precisely located on the positioning element by a cooperation between the locating structure and the positioning structure, the incident surface contacting the second surface; a first lens formed on the incident surface and aligned with the photoelectric element; a second lens formed on the emitting surface and optically aligned with the first lens via the reflecting surface; and an optical fiber arranged to aligned with the second lens.
