After the door of the distribution box is closed, the electromagnet body 103 adsorbs the iron plate 203 to keep the L-shaped plate A101 and the L-shaped plate C201 relatively stable, so that the box door and the box body are firmly connected, dust is not easy to enter, and the explosion-proof capability of the box door is enhanced. This solves the problem that after long-term use, the door lock of the box door becomes loose, resulting in the box door being loose relative to the box body.

[0038] Specifically, L-shaped plates B104 are fixed at both ends of the opening of the U-shaped bracket 102, and studs 105 are threadedly passed through the vertical section of the L-shaped plate B104.
