ンサを得る製造方法を提示するものである。 A conventional film capacitor with a foil-wound tab structure consists of a dielectric film such as polyethylene terephthalate and an electrode foil such as aluminum foil that are alternately overlapped and wound, and a lead wire is drawn out from the electrode foil in the middle of the winding. After winding, the element is heated and pressed to make it into a flat shape, and then impregnated with resin and hardened.
The main manufacturing process is to coat the product with a top coat of resin and harden it. The impregnation and sheathing processes are the main processes that determine the quality of the capacitor, as is the winding process, and are usually carried out in a vacuum. This is to ensure that the impregnation sufficiently penetrates into the element to maintain stable characteristics, and to eliminate defects due to pinholes caused by air bubbles and the like. Thermosetting resins such as epoxy resins are generally used as resins. Instead of vacuum impregnation in the above manufacturing process, in the present invention, a film coated with thermoplastic resin on one or both sides is alternately layered with electrode foil made of aluminum foil, etc., and then wound or laminated. The present invention presents a manufacturing method for obtaining a film capacitor in which the obtained element is heated and pressed into a flat shape, and then the surface of the element is covered with a thermosetting resin.

いる。 It is generally known that a film coated with resin is wound with electrode foil.
The present invention is characterized in that a capacitor is obtained by covering an element made of a thermoplastic resin as the resin with a thermosetting resin, and the effect is that the adhesion between the film and the electrode foil increases. At the same time, the vacuum impregnation process is eliminated, which not only simplifies one part of the process, but also makes use of the characteristics of thermoplastic resin and thermosetting resin to obtain a capacitor of stable quality overall. At the point. That is, only the inside of the element is coated with a thermoplastic resin that has good adhesion to the film and electrode foil, and although this has good moldability, it is easily deformed by heat. In order to overcome this problem, the exterior was made of thermosetting resin, and by taking advantage of the thermosetting resin's resistance to thermal deformation, it was given a function to protect the interior from thermal changes. In general, thermoplastic resins have good moldability but can be subject to thermal deformation, but by using thermosetting resins in combination, we can take advantage of the good moldability of thermoplastics and suppress thermal deformation. The focus was on The base film is made of polyethylene terephthalate, and the thermoplastic resin used to coat it is polyolefin, polystyrene, polycarbonate, etc., and the thermosetting resin is epoxy, phenol, etc. Since the composite dielectric of the film and resin affects the characteristics of the capacitor, it is best to select a wide range of suitable resins. Also, in terms of performance, it is as good as conventional products in terms of voltage resistance and heat resistance.
