[0002] In traditional circuit board installation technology, the circuit board is generally fixed in the card slot by interference fit, and the circuit board is clamped to avoid falling out. However, this circuit board installation method has the following disadvantages: the circuit board is prone to deformation during pressing into the card slot, which can increase the scrap rate. Therefore, further improvement is needed to overcome the shortcomings of circuit board installation. SUMMARY
[0003] Therefore, it is necessary to provide a circuit board mounting structure and electronic equipment to overcome the problem of deformation of the circuit board during pressing into the card slot, which can increase the scrap rate.

[0005] The first aspect of the present application discloses a circuit board mounting structure, which can be accurately installed at a specified position by the setting of the card slot, and has good stability. The protective structure is located at the end and side of the circuit board, and can abut the slot wall of the card slot during pressing the circuit board into the card slot, so the protective structure bears the main stress, and even if the protective structure deforms, the circuit board will not deform. This design effectively protects the integrity of the circuit board when the circuit board and protective structure are in interference fit with the card slot, and there is no gap between the circuit board and the card slot, which ensures that external factors such as vibration will not cause the circuit board to fall off, and enhances the stability and durability of the circuit board. Moreover, the installation method is simple and convenient, and the circuit board can be pressed into the card slot without additional tools, which reduces the assembly difficulty.
[0006] In one of the embodiments, the protective structure comprises sawteeth, the number of the sawteeth is multiple, the sawteeth are arranged on the circuit board and located at the end of the circuit board, the sawteeth are arranged along the width direction of the circuit board in sequence, and the sawteeth are in abutment with the slot wall of the clamping slot. When the circuit board is pressed into the clamping slot, the sawteeth can be in abutment with the slot wall of the clamping slot at multiple positions by arranging the sawteeth along the width direction of the circuit board in sequence. This design can comprehensively protect the circuit board, avoid the failure of the circuit board during the pressing process, and improve the firmness and stability of the circuit board. Moreover, even if the size of the clamping slot has a certain tolerance range, the sawteeth can compensate for the difference by elastic deformation.

This design effectively protects the integrity of the circuit board 2 from being affected when the circuit board 2 and the protective structure 3 are in interference fit with the clamping groove 101, and there is no gap between the circuit board 2 and the clamping groove 101, which ensures that external factors such as vibration will not cause the circuit board 2 to fall off, thereby enhancing the stability and durability of the circuit board 2.
