[0040] More specifically, the main body 120 includes a sleeve structure fitted over the terminal block 110.

[0045] In this embodiment, the U-shaped grounding piece 121 and the sleeve structure are clamped and fixed, which can effectively ensure the positional relationship between the U-shaped grounding piece 121 and the power line, so that the device terminal with the corresponding clamping structure can be smoothly connected to the U-shaped grounding piece 121 on the power line, that is, the leakage electrical signal on the surface of the device can be grounded along the U-shaped grounding piece 121 on the power line.

[0046] More specifically, the U-shaped grounding piece 121 includes a U-shaped clamp and a connecting end; the U-shaped clamp is clamped on the connecting block, and the closed end of the U-shaped clamp abuts against the end edge of the connecting block away from the connecting line 200; the connecting end is connected to one side edge of the open end of the U-shaped clamp and is integrally formed.
