Description

Technical Field

[0001] This utility model relates to the field of printed circuit board mounting technology, specifically to a mounting component and a printed circuit board. Background Technology

[0002] With the rapid development of integrated circuit devices across a wide range of products, mounting these devices onto printed circuit boards (PCBs) has become a challenge. To save space, PCBs are sometimes stacked together. When integrated power devices are connected to PCBs, the boards are prone to bending, which damages conductive traces on the PCB, harms electronic components on other PCBs, and generates unnecessary power losses in the system. In some cases, these consequences are mitigated by using known supports to increase support for the PCB assembly. Typically, supports are mostly cylindrical and use fasteners such as springs, elastic legs, or screws to secure the PCB with the help of through-holes on the PCB. The existing Chinese patent document CN210986576U discloses a mounting assembly for a printed circuit board. It proposes that conventional printed circuit boards are usually fixed with bolts. When the printed circuit board is large, multiple bolts are required for fixing. When the circuit board fails, removing multiple bolts is not only tedious and labor-intensive, but also prone to damaging the circuit board and its electronic component connection wires when tightening the bolts. The solution is to use a limiting mechanism to connect the main board to four fixing blocks. Then, the fixing blocks are connected to the outside through mounting holes, thus fixing the position of the main board and avoiding damage to the electronic component connections during the fixing process.

[0003] However, in the above solutions and existing technologies, because the limiting mechanism is fixed inside the fixing block by a spring, the limiting rod needs to be pulled to install the printed circuit board. Furthermore, if the limiting rod is damaged, it cannot be quickly replaced, which increases the cost of use.

[0004] Therefore, this utility model proposes an mounting component and a printed circuit board to solve the above problems. Utility Model Content
