[0020] The wire trough is combined with the wire clamp 8 to facilitate threading and fixing the wires, and the design of the protective cover 9 can prevent rainwater from entering the box body 1 through the wire trough. The fixing plate 22 on the side of the storage box 7 is placed on the positioning plate 20, and the positioning column 21 is inserted into the positioning hole, so that the storage box 7 can be installed. The desiccant is placed in the storage box 7, so that the inside of the box body 1 can be dried.
[0021] The filtering and dehumidifying assembly includes a processing box 12 installed on the top of the ventilation pipe 5, with air inlets at both ends of the processing box 12, and filters 13 are installed at the air inlets. A fixing box 14 is symmetrically fixed to both sides of the ventilation pipe 5 at the bottom of the processing box 12, and a water-absorbing sponge 15 is placed in the fixing box 14.
