The silicone pad 4-9 is respectively pressed on the first magnetic ring 4-11 and the fourth magnetic ring 4-14, and then the gasket 4-10 is pressed on the silicone pad and fixed to the integrated housing 4-1 by bolts, ensuring the tight fit of the first magnetic ring 4-11, the second magnetic ring 4-12, and the third magnetic ring 4-13, the fourth magnetic ring 4-14.

[0049] One end of the positive busbar 4-2 and the negative busbar 4-3 are respectively connected to the first fast charge relay 1-10 and the second fast charge relay 1-6 by bolts, and the other end is connected to the thin film capacitor by bolts; the fast charge positive copper bar 4-4 is connected to the first fast charge relay 1-10, the third fast charge relay 1-9, and the positive plug-in, and the fast charge negative copper bar 4-5 is connected to the second fast charge relay 1-6 and the negative plug-in; the thin film capacitor is potted on the integrated housing 4-1.

The power module 5-1 is installed on one side of the PCBA board 5-2 and is connected by welding. This component form avoids the risk of solder slag falling on the box body during the installation and welding of the PCBA board 5-2 and the power module 5-1 on the box body, which may cause high-voltage short circuit.
