[0026] Preferably, a reinforcing plate 3 is installed on the inner wall of the shielding frame 2, and the reinforcing plate 3 is fixedly connected to the shielding frame 2;

[0027] By setting the reinforcing plate 3, the load-bearing capacity and stability of the shielding frame 2 are increased, ensuring the safety of the shielding frame 2 during use and reducing the possibility of the shielding frame 2 breaking.

[0028] Preferably, L-shaped solder feet 8 are installed on the outer wall of the shielding cover 5. Multiple sets of L-shaped solder feet 8 are provided, and the L-shaped solder feet 8 are fixedly connected to the outer wall of the shielding cover 5.

[0029] By setting up L solder feet 8, it is convenient for users to install and fix the device to the circuit board later, ensuring the safety of the device during use and avoiding the trouble of device installation.

[0030] Preferably, the shielding cover 5 has a heat dissipation hole 6 inside the upper part, and there are multiple sets of heat dissipation holes 6. The opening diameter of the heat dissipation hole 6 is small.

[0031] By setting heat dissipation holes 6, the heat generated by the operation of electronic components on the circuit board can be dissipated, preventing heat accumulation and thus affecting the performance of the device.

[0032] Preferably, the sealing strip 12 has a U-shaped groove 13, which is movably engaged with the clamping plate 11;

[0033] By setting the U-shaped groove 13, the sealing strip 12 can be accurately positioned and installed, which provides convenience for users and avoids the trouble of inconvenient installation of the device.

[0034] Preferably, the outer side wall of the shielding cover 5 is provided with a fastening groove 16, and multiple sets of fastening grooves 16 are provided.

[0035] By setting the buckle slot 16, it is convenient for users to disassemble the shielding cover 5 later, which improves the flexibility and convenience of the device.

[0036] Preferably, the mounting plate 10 has a countersunk groove 14 located above the screw hole 9, and a bolt 15 is installed in the countersunk groove 14.

[0037] By setting the countersunk groove 14, the bolt 15 can be stored and fixed, preventing the bolt 15 from being exposed outside the device and thus affecting the aesthetics of the device.

[0038] The working principle and process of this utility model are as follows: When connecting the shielding frame 2 and the shielding cover 5 during use, the user places the shielding frame 2 inside the shielding cover 5. During placement, the elastic retaining ball 4 of the shielding frame 2 is engaged with the retaining groove 7. At this point, the shielding frame 2 and the shielding cover 5 are connected. Then, the shielding frame 2 is placed on the circuit board to be installed, and then the L-shaped solder feet 8 are used to fix it as a whole. This allows for the installation and fixation of the device, facilitating future maintenance and replacement by the user. It increases the practicality and convenience of the device and avoids the inconvenience of disassembly and assembly. During the installation process... When sealing is required, the user first places the sealing strip 12 under the shielding cover 5 and presses the sealing strip 12 tightly against the lower outer wall of the shielding cover 5. Then, the user places the mounting plate 10 with the retaining plate 11 on the outer wall of the shielding cover 5 and clamps the retaining plate 11 into the U-shaped groove 13 of the sealing strip 12. Then, the user aligns the screw holes 9 of the mounting plate 10 with the screw holes 9 of the shielding cover 5. After alignment, the user screws the bolts 15 into the screw holes 9 one by one until the bolts 15 are fully screwed into the countersunk groove 14. This can seal the device, reduce electromagnetic interference, improve equipment performance and stability, protect sensitive components, and extend equipment life.
