Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a power distribution device and a charging pile. Background Art

[0002] Currently, the power distribution module used in the DC charging cabinet is too miniaturized, so the positive and negative contactor groups, including several connecting copper bars, are passed through the circuit board, and the negative contactor group and positive contactor group control connectors are provided on the bottom surface of the circuit board.

[0003] The above method causes excessive heat concentration on the copper busbar, which in turn affects the components on the circuit board. In addition, the circuit board is penetrated by the copper busbar and relays, and the distance between the weak current and the strong current is very close, which brings about the problem of insufficient insulation voltage resistance. When charging multiple electric vehicles, there is a risk of short circuit and loss of control. Utility Model Content
