Abstract

Abstract A photoelectric transducer includes a conductive case having an optical connector receptacle and circuit board forming a photoelectric transducer circuit. Conductive stands are erected from the bottom of the conductive case to bridge-support the opposite ends of the circuit board. The stands have first grounding terminals connected to grounding lines of the circuit board and also second grounding terminals penetrating the conductive case for outward projection. The positioning and assembling of the circuit board can be simplified, a shield structure can be readily formed, and it is ensured that the connection terminals are out of contact with the conductive case. With this structure, the photoelectric transducer can be rendered compact.
