Abstract

The present invention provides a capacitor for an inverter of a vehicle comprising a case; a plurality of capacitor unit modules; positive and negative bus plates that are disposed in the case to be connected to the capacitor unit modules; and a power module corresponding to the unit modules, wherein that the unit modules are insulated from each other through an insulating material, and wherein the bus plates each comprise a bus bar that overlaps with the other bus bar and is electrically connected to the power module.

Claims

1. A capacitor for an inverter of a vehicle, comprising:

a case;

a plurality of capacitor unit modules;

positive and negative bus plates that are disposed in the case and connected to the capacitor unit modules; and

a power module corresponding to the unit modules,

wherein the unit modules are insulated from each other through an insulating material, and

wherein the bus plates each comprise a bus bar that are overlaps with the other bus bar and is electrically connected to the power module.

2. The capacitor of claim 1, wherein the respective bus plates comprise a plate body, and wherein the bus bar is formed at an edge end of the plate body.

3. The capacitor of claim 2, wherein the bus bars each comprise an overlapped portion that is extended outside of the edge end of each plate body to be overlapped with each other, and a terminal portion that is integrally formed with the overlapped portion to be electrically connected to the power module.

4. The capacitor of claim 3, wherein each overlapped portion is extended upwards from the edge end based on the flat surface of the plate body, and then bent downwards.

5. The capacitor of claim 1, wherein the insulation material comprises epoxy resin that can be hardened between the positive and negative bus plates.

6. The capacitor of claim 3, wherein the terminal portions of the respective bus bars are coated by an epoxy resin.
