Problems solved by technology

The above-mentioned method of fixing pins by manual soldering has the disadvantages of low efficiency, difficult control of heating time, low first pass rate, high reject rate, and difficult process control.
Rotation will bring about the position of the assembled flexible bridge printed circuit, which will not be accurately and consistently misaligned
Misalignment will cause great difficulties for subsequent module-level product assembly
If it is forcibly assembled in subsequent module-level products, it will increase the internal stress of the flexible bridging printed circuit board, causing the circuit board to break and be scrapped

Embodiment Construction

[0020] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

[0021] refer to figure 1 , the main body of the optical transceiver device 21 is a square structure, on which a receiving end and a sending end with end faces perpendicular to each other and with pins are arranged. The cylindrical body whose one side protrudes vertically from the front end face 22 is a light-conducting metal piece. The cylinder on the side opposite to the light-conducting metal part is the origin of the light-transmitting device 21 . The end face of the originating end is the originating metal end face 27 . The mutually insulated starting pins 28 protrude from the surface of the starting metal end surface 27 . There is a receiving end of the optical transceiver device 21 on one side of the main body in the middle part between the light-conducting metal piece and the sending end. The end face of the receiving end is the receivin...

Abstract

The invention discloses a method for reliably connecting bridge printed circuit boards of optical transceivers and a positioning component, aiming to provide a method which has the advantages of convenient operation, reliable connection, high speed and high efficiency, does not damage the optical transceiver easily and can reliably connect pins of the receiving end and the transmitting end of an optical transceiver with a bridge printed circuit board. The method mainly comprises the following steps: preparing a U-shaped clamping groove on the side end of the bridge printed circuit board; arranging an insulating piece between the pins of the optical transceiver and the bridge printed circuit board; putting the optical transceiver into a positioning base seat which can limit the axial free degree of one end; sliding a fixed pressing block provided with a stop end surface and a guiding key into a guiding groove of the positioning base seat; clamping a crosslinking lug boss on the extension pin end of the fixed pressing block into the U-shaped clamping groove; moving the positioning component of the optical transceiver into an opening of a C-shaped clamping piece with a fastening bolton the open end; fixing the positioning component and finally fixing the pins of the transmitting end and the receiving end on a welding disk by tin soldering. The method has high efficiency and convenient operation.

Description

technical field [0001] The invention relates to a method and a positioning assembly for connecting the receiving end and sending end pins of the optical transceiver device and the bridging printed circuit board when assembling the optical transceiver device in the optical fiber communication system. Background technique [0002] In the prior art, a bridging printed circuit board made of bendable and flexible material is provided with a through hole with a disc-shaped pad. When connecting the receiving end and the transmitting end of the optical transceiver device, the flexible bridging printed circuit board is close to the metal end faces of the receiving end and the transmitting end, and the pins on the vertical end faces of the receiving end and the transmitting end of the optical transceiver device pass through the through hole of the above-mentioned pad, tightly Paste bridges the surface of the printed circuit board. Solder by manual operation, and its pins are fixedly ...
