Optical connector with alignment device

摘要

An optical connector includes a printed circuit board, a photoelectric element, a positioning element, and a lens element. The positioning element is positioned on the printed circuit board and covers the photoelectric element. The positioning element includes a top surface facing away from the printed circuit board, and defines a through hole in a top surface thereof to expose the photoelectric element. The positioning element also includes a mark system formed on the top surface for facilitating alignment between the positioning element and the photoelectric element. The lens element is positioned on the positioning element and includes a first surface facing the photoelectric element, and a first lens aligned with the photoelectric element.

1. An optical connector, comprising:
a printed circuit board comprising an upper surface; a photoelectric element positioned on the upper surface; a positioning element positioned on the upper surface and covering the photoelectric element, the positioning element comprising a top surface facing away the upper surface and a bottom surface contacting and overlapping with the upper surface, the top surface and the bottom surface positioned at opposite sides of the positioning element, the positioning element defining a through hole extending through the top surface and the bottom surface to expose the photoelectric element, the positioning element comprising a mark system formed on the top surface for facilitating alignment between the positioning element and the photoelectric element, the through hole being substantially rectangular, the mark system comprising a line-shaped first mark line parallel with a short side of the through hole and a line-shaped second mark line parallel with a long side of the through hole, when the positioning element is aligned with the photoelectric element, the first mark line passes a center of the photoelectric element, and the second mark passes the center of the photoelectric element; and a lens element positioned on the positioning element, the lens element comprising a first surface facing the photoelectric element and a first lens aligned with the photoelectric element.
