Embodiment 1
[0019] Embodiment one is the single-core structure of the capacitor core, see figure 1 As shown, a film capacitor includes a shell 2 and a plastic positioning cover 3, the shell is made of an aluminum cylindrical shell, and the cavity formed by the shell 2 and the plastic positioning cover 3 is provided with a capacitor core 1 and a potting material 4 , the potting material 4 is made of polyurethane / epoxy resin, and the plastic positioning cover 3 is provided with a lead-out electrode 6, which is connected to the capacitor core 1 through the connection copper strip 5, and the connection between the lead-out electrode 6 and the connection copper strip 5 is also passed through Layer busbar connection, the laminated busbar includes a lower busbar 61 with one lead-out electrode, an upper busbar 62 with another lead-out electrode, an insulating paper 63 is arranged between the upper busbar 61 and the lower busbar 62, See the specific structure image 3 shown.

Embodiment 2
[0021] Embodiment two is the double-core structure of the capacitor core, see figure 2 As shown, the structure is basically the same as that of Embodiment 1, the difference is that connecting the copper strip 5 requires connecting two cores.
[0022] The capacitor of the present invention improves the structure of the original conventional product, adding an integrated lead-out laminated busbar inside, which greatly improves the capacitor technology level, has a strong conduction over-current capability, and also serves as a heat sink for the lead-out end. The electrical properties can effectively shield the high-frequency induced eddy current, distribute the current direction reasonably, and make the capacitor reach the minimum ESR and ESL, greatly reduce the heating of the capacitor, enhance the heat dissipation capacity of the capacitor, and make the product performance better, safer and more reliable; at the same time, the capacitor core can be used according to the curren...
