Abstract:
1. A method for connecting a bus bar to a capacitor, the capacitor comprising a plurality of capacitor devices, each of the capacitor devices having been fabricated by winding or depositing a vapor-deposited metal film on either or both sides of a plastic film and forming polar plates, that is, sprayed surfaces on both sides of the wound vapor-deposited film by spraying Zn, Zn alloy, tin, or Zn firstly and tin secondarily, the method comprising: connecting a plurality of lead frames arranged alternately on opposing sides of one of the pair of bus bars to the sprayed surfaces disposed at opposite sides of neighboring capacitor devices, the alternating lead frames electrically facing in a direction along a diagonal line; connecting a plurality of lead frames arranged alternately on opposing sides of the other one of the bus bars to the sprayed surfaces, the alternating lead frames of the other one of the bus bars electrically facing in another diagonal line crossing the diagonal line; and assembling the pair of bus bars to be insulated from each other and overlapped at one side of the capacitor device.
