Photoelectric converter capable of emitting stable optical signal

摘要

A photoelectric converter includes a circuit board, a laser diode electrical mounted on the circuit board, a supporting frame, an optical transmission member mounted on the supporting frame, a beam splitting assembly and an optical sensor positioned beside the beam splitting assembly. The laser diode, the beam splitting assembly and the optical sensor are received in a space cooperatively defined by the supporting frame and the optical transmission member. The laser diode emits optical signals. A part of optical signals is refracted by the beam splitter and transmitted to the optical transmission member, and the other part of optical signals is reflected by the beam splitter to the optical sensor.

1. A photoelectric converter, comprising:
a circuit board; a laser diode electrically connected to the circuit board; a beam splitting assembly covering the laser diode, and comprising a first supporting portion, a second supporting portion, and an beam splitter, the first supporting portion and the second supporting portion being perpendicularly mounted on the circuit board, the second supporting portion defining an opening hole at an end thereof adjacent to the circuit board, the beam splitter interconnecting the top end of the first supporting portion and the top end of the second supporting portion, and a height of the first supporting portion being less than that of the second supporting portion; an optical sensor electrically mounted on the circuit board, and located beside the opening hole; a supporting frame mounted on the circuit board to surround the laser diode, the beam splitting assembly, and the optical sensor; and an optical transmission member mounted on the supporting frame opposite to the beam splitting assembly, wherein the laser diode emits one or more optical signals, and a part of optical signals are refracted by the beam splitting assembly to the optical transmission member, and the other part of optical signals are reflected by the beam splitting assembly to the optical sensor.
