Claim Text:
1. An optical-electric converting module, comprising: a printed circuit board (PCB) comprising a supporting surface, at least one laser diode and at least one photo diode, the at least one laser diode and the at least one photo diode positioned on the supporting surface and electrically connected to the PCB; a bracket comprising a first surface and a second surface facing away from the first surface, the first surface resting on the supporting surface, the bracket defining a through window running through the first surface and the second surface, the bracket detachably connected to the supporting surface of the PCB, with the at least one laser diode and the at least one photo diode being received in the through window; and an optical-electric coupling element detachably connected to the second surface of the bracket, and comprising a lower surface and an upper surface facing away from the lower surface, the upper surface being substantially parallel with the lower surface, the optical-electric coupling element defining a first cavity in the lower surface, and a second cavity in the upper surface, the second cavity comprising a bottom surface and a sloped surface directly connected to the bottom surface, the bottom surface being substantially parallel with the upper surface, and an included angle between the bottom surface and the sloped surface being about 45 degrees; wherein the PCB comprises a rear surface facing away from the supporting surface, the PCB defines two first locating holes running through the supporting surface and the rear surface, the bracket comprises two first locating poles perpendicularly extending downwards from the first surface, and the first locating poles are inserted into the first locating hole as a pinch fit to firmly attach the bracket onto the PCB; the bracket defines two second locating holes running through the first surface and the second surface, the optical-electric coupling element comprises a lower surface, the optical-electric coupling element comprises two second locating poles perpendicularly extending downwards from the lower surface, and the second locating poles are inserted into the second locating holes as a pinch fit to firmly attach the optical-electric coupling element onto the second surface of the bracket.
