no. 1 approach
[0034] Such as figure 1 As shown, the film capacitor 1 according to the first embodiment of the present invention is a wound-type metallized film capacitor, and includes an internal electrode 10 and two end faces 10A, 10B formed in the width direction of the internal electrode 10 to lead out the electrodes. to the external end face electrodes 11A, 11B.
[0035] The internal electrodes 10 are formed by winding a metallized film 12 . The metallized film 12 has aluminum vapor-deposited on a polypropylene film as a dielectric film. A plurality of metallized films 12 can be stacked and wound.
[0036] The metallization layer is formed by spraying the alloy for thermal spraying mentioned later of this invention about end surface electrode 11A, 11B. The outer peripheries of internal electrodes 10 and end surface electrodes 11A and 11B are covered with insulator 13 . Lead wires 14A and 14B are joined to end surface electrodes 11A and 11B so as to protrude from insulator 13 , resp...
no. 2 approach
[0038] Such as figure 2 As shown, the film capacitor 2 of the second embodiment is a laminated metallized film capacitor, and includes an internal electrode 20 and two end faces 20A and 20B formed in the width direction of the internal electrode 20 so that the electrodes are led out to the outside. Electrodes 21A, 21B.
[0039] The internal electrodes 20 are laminated with a plurality of metallized films 22 formed by vapor-depositing aluminum on a polypropylene film as a dielectric film. The vapor-deposited portions 22 a of the metallized film 22 on which aluminum is vapor-deposited are laminated so as to protrude alternately from the end faces 20A and 20B.
[0040] The alloy for thermal spraying which will be mentioned later of this invention is thermal sprayed about end surface electrode 21A, 21B, and the metal sprayed layer is formed. The outer peripheries of internal electrodes 20 and end surface electrodes 21A and 21B are covered with insulator 23 . Lead wires 24A and...
no. 3 approach
[0042] Such as image 3As shown, the film capacitor 3 of the third embodiment is an electrode foil type film capacitor, and includes an internal electrode 30 and end surface electrodes formed on both end surfaces 30A and 30B in the width direction of the internal electrode 30 to lead the electrodes to the outside. 31A, 31B. In this figure, a part of the internal electrode 30 is exploded for convenience of description.
[0043] The internal electrode 30 has metal foils 30a, 30b and dielectric thin films 30c, 30d. Aluminum is used for metal foil 30a, 30b of this embodiment. The metal foil 30a and the dielectric film 30c are stacked so that the metal foil 30a protrudes from the one end surface 30A side with respect to the dielectric film 30c, and an electrode film 30C is formed. The metal foil 30b and the dielectric film 30d are stacked so that the metal foil 30b protrudes from the other end surface 30B side with respect to the dielectric film 30d to form an electrode film 30D...
