[0029] The present application provides a busbar assembly and an assembled printed circuit board, such as Figure 1 As shown, the busbar assembly includes: a plurality of busbars 1 and a bracket 2; wherein the bracket 2 has a receiving cavity 21, and the busbar 1 is received in the receiving cavity 21; the busbar 1 has a first layer of busbars 14 and a second layer of busbars 15, and the second layer of busbars 15 is superimposed on the first layer of busbars 14.

[0030] In this embodiment, in order to facilitate the arrangement of circuits in the prior art, the size of the printed circuit board 3 is enlarged, and a bus is added for jumpering. However, the present application provides the bracket 2 and the accommodating cavity 21 on the bracket 2.
