Abstract
The utility model relates to the technical field of power supplies, in particular to a power supply module, which comprises a plastic shell, an inner circuit board, an outer circuit board and a metal grounding piece, and is characterized in that the inner circuit board is mounted in the plastic shell; an opening is formed in the plastic shell, and the outer circuit board is mounted outside the opening and is grounded; the metal grounding piece is installed on the plastic shell, one end of the metal grounding piece extends to the inner circuit board and is connected with the inner circuit board, and the other end of the metal grounding piece extends to the outer circuit board and is connected with the outer circuit board. Therefore, the material of the shell is changed from metal to plastic, the cost is reduced, the lightweight design is facilitated, the plastic shell is provided with the metal grounding piece, the connection of the inner circuit board and the outer circuit board is realized, the grounding treatment of the inner circuit board is realized, and the metal grounding piece is fixed on the plastic shell in a clamping manner, so that the metal grounding piece is convenient to use. And the metal grounding piece is locked with the plastic shell and the inner and outer circuit boards by matching with bolts, so that the metal grounding piece is not easy to fall off and deviate, and is safer and more reliable.
