Detailed ways

The utility model will be described in further detail below through specific embodiments in conjunction with the accompanying drawings.

As shown in FIG. 1 and FIG. 2 , in the embodiment of the present invention, a power supply box is provided, which includes a box body 1 , a power supply 2 , a circuit board 3 , a switch 4 , a socket 5 and a power supply filter 6 .

The box body 1 has a square structure and includes a main box body 11 , a panel 12 and a cover plate 13 . The main box body 11 , the panel 12 and the cover plate 13 enclose the box body 1 . A fixing plate 14 for fixing and installing the power supply 2 is also provided in the main box body 11 . The panel 12 is provided with holes for inlaying and fixing the switch 4 and the socket 5 . The side plate of the main box body 11 is provided with heat dissipation holes or heat dissipation grooves for heat dissipation.

The power supply 2 adopts the CMG-H150D12G+24 switching power supply. The power supply 2 is installed in the box body 1 and supports AC and DC output at the same time.

The circuit board 3 is fixedly mounted on the inside of the panel 12 of the box body 1 , and is electrically connected to the power supply 2 to control the charging and discharging of the power supply 2 . The circuit board 3 can be programmed to customize the switch of the control power supply, and control the output of the AC and DC power supply. The power supply box can be turned on and off at regular intervals, and the alternating current and direct current can be converted at regular intervals.

The switch 4 and the socket 5 are respectively inlaid and fixed on the panel 12. The switch 4 is electrically connected to the circuit board 3. The switch 4 is a boat-shaped switch, and it needs enough force to switch the contacts, so that the switch 4 will not be easily opened by mistake. break, improving the safety factor. The socket 5 is electrically connected to the power supply 2, and the socket 5 includes two-level and three-level sockets, and is provided with multiple two-level and three-level sockets, which can satisfy multiple devices to supply power at the same time.

The power filter 6 is an electromagnetic interference power filter capable of attenuating common-mode interference and differential-mode interference. The power filter 6 is electrically connected between the power supply 2 and the socket 5, and filters and shapes the current output by the power supply 2 to stabilize the output. current.

In the power supply box provided in this embodiment, since a power supply filter 6 is provided between the power supply 2 and the socket 5, the current output by the power supply 2 is filtered by the power supply filter 6 to form a stable current, so that the power supply box can output stable current to external devices , providing stable power supply and improving safety performance.

The above uses specific examples to illustrate the utility model, which is only used to help understand the utility model, and is not intended to limit the utility model. For those skilled in the technical field to which the utility model belongs, some simple deduction, deformation or replacement can also be made according to the idea of the utility model.
