The grounding metal plate 4 has a vertical conductive piece 41. The grounding metal plate 4 and the conductive piece 41 are integrally bent and formed. The conductive piece 41 is inserted into the lower cover 1 of the plastic housing from bottom to top, and the metal jumper 21 of the circuit board 2 is placed in the mounting slot 411. The metal jumper 21 is connected to the grounding metal plate 4 through the conductive piece 41. Finally, the upper cover 3 of the plastic housing is installed on the top of the lower cover 1 of the plastic housing. The plastic housing lower cover 1, the circuit board 2, the plastic housing upper cover 3, the grounding metal piece 4, the conductive piece 41, the mounting slot 411, and the metal jumper 21 are used to achieve grounding and conduction between the grounding metal piece 4 and the circuit board 2 through a clip-on structure.
