Description

A convenient plug-in power circuit board fixed installation structure

Technical Field

The utility model relates to the technical field of circuit structures, and in particular to a conveniently pluggable fixed installation structure for a power circuit board.

Background Art

A printed circuit board (PCB) is a plate-like carrier used for the installation and connection of electronic components, usually made of copper-clad laminate. Circuit patterns are made on the circuit board through chemical corrosion, mechanical processing and other processes to form circuit connections. Circuit boards are widely used in electronic products such as computers, mobile phones, televisions, cars, etc. The main function of a circuit board is to provide electrical connections, mechanical support and signal transmission. It can combine multiple electronic components (such as capacitors, inductors, transistors, etc.) and connect them through circuit patterns to form a complete circuit system. In this way, the circuit design of electronic products can be realized on a miniaturized and compact board, which improves the reliability and work efficiency of electronic products. However, in order to ensure the good signal conduction, some circuits have boards that are directly connected to each other through plug-ins, especially when multiple boards need to be connected to a motherboard.

However, the above method has the following defects:

In order to achieve the corresponding functions, multiple power circuits are interconnected, but they take up a lot of space and cannot be used in a small space. Multiple power circuit boards generate a lot of heat. If the board is vertically inserted into the mainboard circuit and only connected and fixed by the socket on the circuit board, it can save space, but it is not reliable, and poor fixation can easily cause the plug-in to be stressed over time, causing the board to fall off or the interface to be damaged, affecting use.
