In this embodiment, the circuit board 200 is substantially rectangular and has a size corresponding to the internal space of the power supply box 100, the power supply box 100 includes an upper cover 105 and a bottom plate 106, and the upper cover 105 and the bottom plate 106 are vertically fastened and fixed by screws 107.

In this embodiment, the high voltage output terminal 203 is disposed on the circuit board 200, and the high voltage outlet 103 electrically connected to the high voltage output terminal 203 is disposed on the power supply box 100. Therefore, the two interconnectable switching power supplies can be interconnected through wiring, namely high voltage of the previous interconnectable switching power supply can be directly connected into the next interconnectable switching power supply, and one power supply can supply power to the plurality of interconnectable switching power supplies.

In order to reduce the winding of the wiring, the power supply box 100 is provided with a high voltage inlet 101 and a high voltage outlet 103 at both sides in the length direction, respectively. The arrangement enables the wiring to be directly connected from one end of one interconnectable switching power supply to the other interconnectable switching power supply without bending the wiring, thereby avoiding winding.
