[0015] Example

[0016] like Figure 1-Figure 3 As shown, a high-voltage distribution panel box includes a panel box shell 1, which serves as a supporting structure of the entire panel box and is made of aluminum alloy.

The positive bus bar 3 and the negative bus bar 4 are respectively located at the upper and lower layers of the panel box shell 1 and are fixedly connected by insulating columns 12. The positive bus bar 3 and the negative bus bar 4 are made of copper, and a plating layer is added to protect the bus bars. Its cross-sectional shape is a rectangular bar, and it can be processed into a suitable shape as needed; the insulating column fixes the positive bus bar 3 and the negative bus bar 4 on the high-voltage disk box 1 and fastens them with bolts, and the material is nylon; the positive bus bar 3 connects the positive fuse 6 and the charging fuse 5, and the positive fuse 6 and the charging fuse 5 are respectively connected to the positive pole of the positive high-voltage output connector 2 and the charging connector 7, and the positive high-voltage output connector 2 and the charging connector 7 are fixed to the outside of the disk box shell 1, and the negative bus bar 4 connects the negative high-voltage output connector 13 and the negative pole of the charging connector 7, and the negative high-voltage output connector 13 is installed on the outside of the disk box shell 1, and the positive high-voltage output connector 2 and the negative high-voltage output connector 13 are connectors for connecting high-voltage loads. Its size and shape adopt connectors that are compatible with the current and voltage of the high-voltage load; the charging connector 7 is used for charging the high-voltage battery, and its size and shape adopt connectors that are compatible with the high-voltage charging current and voltage;

[0017] The positive bus bar 3 and the negative bus bar 4 are respectively connected to the power connector 10, which is an interface connector for connecting the high-voltage battery to the high-voltage box 1. Its size and shape are adapted to the current and voltage of the interconnection between the boxes, and it is fixed to the high-voltage box 1 by bolts.

[0018] The positive bus bar 3 and the negative bus bar 4 are respectively connected to the connecting connector 9, which is an interface connector for interconnecting multiple high-voltage boxes 1.
