Figure 2 The power distribution unit can include a plurality of power distribution boards 201, a conductive array 202, a tail connecting piece 203, an input end 204, and an output end 205.

[0048] The plurality of power distribution boards 201 can be arranged in a vertical stack, the conductive array 202 can be located below the plurality of vertically stacked power distribution boards 201, and the conductive array 202 is connected to each power distribution board 201.

[0049] In addition, the input end 204 and the output end 205 can be arranged on the tail connecting piece 203, the input end 204 can be connected to each power distribution board 201, and the output end 205 can be connected to the conductive array 202, so as to form a circuit loop composed of the input end 204, the power distribution board 201, the conductive array 202, and the output end 205.

[0050] In addition, in actual application, the conductive array 202 can be connected with the adjacent power distribution board 201, and the power distribution boards 201 are connected with each other, or the conductive array 202 can be connected with each power distribution board 201, and the connection mode between the conductive array 202 and the power distribution board 201 is not limited in the embodiment of the application.
