Abstract
This capacitor structure is provided with a capacitor body in which a plurality of wound-type capacitors are housed in a housing, and which is fixed to a fixing object via a fastening tool (a cylindrical member and a fixing bolt). The capacitor structure is configured such that the capacitor body is fixed to the fixing object by inserting the fastening tool into at least one of a gap formed between the outer peripheral surfaces of the wound-type capacitors or gaps formed between the outer peripheral surfaces of the wound-type capacitors and the inner wall of the housing, in a state in which the wound-type capacitors are installed side by side on the floor of the housing.

A capacitor structure comprising:
- a plurality of wound-type capacitors;
- a housing which houses the plurality of wound-type capacitors;
- and
- a fastener which fixes a capacitor body in which the plurality of wound-type capacitors are stored in the housing to a fixing object,
- wherein, in a state in which the wound-type capacitors are arranged side by side on a bottom of the housing, the capacitor body is configured to be fixed to the fixing object by inserting the fastener into at least one of gaps formed between outer peripheral surfaces of the respective wound-type capacitors or formed between the outer peripheral surfaces of the respective wound-type capacitors and an inner wall of the housing,
- the housing into which the wound-type capacitors and the fastener are inserted is filled with a resin and the wound-type capacitors are fixed in the housing by the resin, and
- the fastener includes:
- a metallic cylindrical member formed to be longer than an overall length of the wound-type capacitors and inserted into the at least one of the gaps;
- and
- a fixing bolt inserted from an outside of the housing into the cylindrical member so as to pass through the cylindrical member and screwed to the fixing object to be fixed.
