The size and shape of the second opening 12 can also be determined according to the actual requirements. A first air inlet 14 is formed on the right side surface of the housing 1. The first air inlet 14 is covered with a dustproof filter screen. The front and back opposite side walls of the accommodating chamber are provided with sliding grooves 15, the sliding grooves 15 are of groove structures, the sliding grooves 15 extend in the left and right directions, and the length of the sliding grooves 15 is determined according to actual requirements. The right end of the slide slot 15 is closed and the left end of the slide slot 15 forms a socket 151 at the edge of the first opening 11. The circuit board 5 is horizontally arranged, and the right end thereof can be inserted into the slide groove 15 through the insertion opening 151 when assembled, and is connected with the slide groove 151 in a sliding fit manner (as shown in fig. 6). The lid 2 has a closed state in which the first opening 11 and the second opening 12 are closed and an open state in which the first opening 11 and the second opening 12 are opened. The cover 2 is connected with the housing 1 in a sliding manner from side to side so that the cover 2 is switched between a closed state and an open state. The lid 2 includes a top plate 21 for covering the second opening 12 and a riser 22 attached to the left end of the top plate 21 for covering the first opening 11. The top plate 21 is provided with the heat radiation fan 3, the lead of the heat radiation fan 3 is provided with a male connector, and the male connector is connected with the female connector on the circuit board 5 in an inserting way, so that the heat radiation fan 3 provides a working power source through the circuit board 5. An air outlet 211 is formed on the top plate 21 corresponding to the heat dissipation fan 3. The air outlet 211 is a grid structure. A plurality of connectors 51 are mounted on the left side of the circuit board 5, and the plurality of connectors 51 are soldered to the circuit board 5 or connected to the circuit board 5 by wires. The plurality of contacts 51 are divided into a plurality of ac contacts and a plurality of dc contacts.
