[0023] Buckle A101 is located on the outside of PCBA board 2, and the bottom frame 1 is provided with a buckle A101; the rotating disc 5 and the buckle A101 on the bottom frame 1 fit to form a reversed bucket-shaped structure and cover the outside of the PCBA board 2, which isolates the PCBA board 2 from the contact area with the external environment, improves the electrostatic protection level to avoid the breakdown of electronic components.

[0024] The buckle A101 and the bottom frame 1 form an expanded hole type ring groove 102 that allows the compression ring 501 at the bottom of the rotating disc 5 to be sealed and inserted, and the expanded hole type ring groove 102 gradually expands in diameter from bottom to top. The expanded hole type ring groove 102 allows the compression ring 501 to be sealed and inserted, thereby providing better sealing effect, preventing static electricity from entering through the gap, and enhancing the overall anti-static ability. The bottom of the rotating disc 5 and the inside of the compression ring 501 are integrally formed with a buckle B502, and the buckle B502 and the compression ring 501 form a buckle groove 503 that cooperates with the buckle A101 to buckle. The buckle B502 and the buckle A101 buckle design allows the rotating disc 5 to be stably connected with the bottom frame 1, forming a more secure sealing structure, further improving the reliability of electrostatic protection.
