Problems solved by technology

[0005] 1. M4 screws need to be installed and removed twice, which is time-consuming and laborious;
[0006] 2. The material of the transistor pressure plate is thermoplastic, and the positioning pin of the transistor is not as flexible as expected. When the transistor is facing down, it cannot support the transistor and the transistor will fall.
During on-site operation, the worker supports the transistor by inserting a toothpick in the via hole of the PCB transistor pin to prevent it from falling, which is time-consuming and laborious, and it is a kind of damage to the pin

Abstract

The invention discloses an assembly used for fixing a transistor. The assembly comprises: a transistor pressing plate and a printed circuit board (PCB). The transistor pressing plate is provided with several countersinks which are connected with the transistor through a spring pin. The transistor pressing plate is prominently provided with several card hooks. The PCB is provided with a card slot.The transistor pressing plate is clamped and connected with the PCB through the card hooks. By using an assembly structure design of the invention, cockamamie screw installation and dismounting can be avoided and stable connection during installing the transistor can be guaranteed.

Description

technical field [0001] The invention belongs to the field of semiconductor devices, and in particular relates to a component for fixing a transistor. [0002] Background technique [0003] The existing transistor fixing structure includes a transistor pressure plate and a printed circuit board (PCB). The fixing principle is: after the transistor pin is bent, insert two transistor positioning pins with a diameter slightly larger than the transistor fixing hole into the transistor fixing hole, and the middle of the positioning pin is opened. The groove, using the elasticity of the plastic, becomes an "elastic pin" structure, which can support the transistor when the transistor is facing down, so that it does not fall off, and then use M4 screws to fix the transistor pressure plate and the transistor as an integral component on the printed circuit board ( PCB), place the "PCB+transistor pressure plate" component on the heat sink, remove the M4 screws, and fix the transistor pr...
