Abstract
The invention provides a DC filtering capacitor for a new energy automobile. The DC filtering capacitor comprises an outer shell, a plurality of pairs of extraction electrodes, wherein the outer shell is in a shape of flat square box convenient for stacking, the extraction electrodes are bent copper sheets provided with mounting holes, the all the copper sheets are positioned on the same plane. The DC filtering capacitor further comprises a connection copper bar made of a whole piece of copper plate, wherein the connection copper bar is welded with the extraction electrodes, and is welded with electrodes of a capacitor core.
Description
Technical field
The invention belongs to new forms of energy car technical field, more particularly to a kind of new-energy automobile DC filter capacitors.
Background technology
DC filter capacitors are widely used in power supply on vehicle, for filtering off circuit in harmonic wave.Existing DC filtering
Capacitor is to be placed in capacitor protector body to constitute by several capacitor element core groups.Single core group is in cylinder, due to cylinder
Gap between shape core group is larger so that the volume of capacitor is larger, is unfavorable for being installed in automobile-used environment.
The content of the invention
The present invention provides a kind of automobile DC filter capacitors.
A kind of automobile DC filter capacitors, the capacitor case is shaped as the flat box-shape for being easy to stack, described
Capacitor has multipair extraction electrode.
The shell of the capacitor is flat square box shape.
The extraction electrode is the copper sheet of the bending with installing hole, and the copper sheet is in same plane.
The capacitor has the connecting copper bar that monoblock copper coin is made, and connecting copper bar is welded with extraction electrode, while welding
The electrode of capacitor body.
The capacitor have at least one as pie flat capacitor body.
The capacitor has the flat capacitor body of 2 more parallels.
The capacitor of the present invention is used for the DC filtering in terms of new-energy automobile electric-control system, supports and use.Advantage is, dry type
Structure, life-span length, loss is little, and conveyance capacity is big.Flame retardant rating UL94-V0, can 105 degree of grades height of long-term work.
