Abstract
The invention discloses a base pin bending fixture of a 4PIN receiver optical subassembly, which comprises a fixing plate, a base pin bending mechanism and a base pin fixing mechanism, wherein the base pin bending mechanism comprises a pedestal, a 4PIN receiver optical subassembly fixing piece and two base pin clamping subassemblies; the pedestal is rotationally arranged on the fixing plate; an accommodation part for fixing the end part of the 4PIN receiver optical subassembly is formed on the 4PIN receiver optical subassembly fixing piece; the two base pin clamping subassemblies are arranged on the two sides of the 4PIN receiver optical subassembly fixing piece respectively; each base pin clamping subassembly comprises a fixing die, a compressing block and a locking piece; the base pin fixing mechanism is fixed at the other end of the fixing plate, and used for accommodating a base pin; the base pin bending mechanism rotates to drive the 4PIN receiver optical subassembly fixed in the accommodation part to rotate; the base pin accommodated in the base pin fixing mechanism is bent opposite to the end part; and the two base pin clamping subassemblies clamp the root of the base pin for protecting the root of the base pin.
Description
technical field [0001] The invention relates to the technology of a 4-pin light receiving component, in particular to a fixture for bent tube pins of a 4-pin light receiving component. Background technique [0002] 4-pin receiver optical subassembly (4PIN Receiver Optical Subassembly, 4PIN ROSA), which generally includes a terminal and pins connected to the terminal. The process of soldering the 4-pin light-receiving component to the printed circuit board is as follows: first, take the root of the two pins of the device as the fulcrum, and forcibly split them upwards by 80-90 degrees, then fix the device and the printed circuit board together, and finally Use scissors to forcibly fold the broken pins back close to the printed circuit board for soldering. After the pins are formed, the end of the printed circuit board bears against the pins to form an included angle. After welding and assembly, the tail of the pins and the fulcrum of the PCBA end will form a lever to generat...
