コンデンサを提供するととＫある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a welded portion of a lead wire of a plastic film capacitor formed by alternately laminating and winding aluminum electrode foil and a plastic film as a dielectric. The objective is to provide a plastic film capacitor with a low incidence of defective products and excellent productivity.

法が行なわ−Ｊ１ている、。In plastic film capacitors, a plastic film is laminated to the metal foil to which the lead wires are welded, but the lead wires themselves and the rough surface caused by welding can damage the laminated plastic film. Since this may reduce the voltage, in conventional plastic film capacitors, a protective film made of a strip of plastic film is placed between the electrode foil 2 to which the lead lt#1 is welded and the dielectric film 6, as shown in Fig. 1. 4 was inserted above the lead wire welding part 5. However, this method ranks 40th on the protective film REZ-J.
1 may occur and the purpose may not be achieved. Therefore, as shown in Figure M2, one end of the protective film 4 is thermally welded 6 to a predetermined position of the dielectric film 6 to prevent the position from shifting. -J1 is here.

はこの問題を解決することを意図するものである。By the way, this method of thermally welding the protective film 4 to the dielectric film 6 deteriorates the unevenness of the dielectric film 6, resulting in a very high rate of defective products. The present invention is intended to solve this problem.

低い温度で所定の位置に接着させることができる。The present invention is characterized in that the protective film is made of a plastic film coated with an adhesive coating. This adhesive retention film is coated with an adhesive that easily adheres when pressure or low temperature tW is applied to one side of the plastic film, so it can be adhered in place at a low temperature that does not damage the dielectric film. be able to.

解消される。As described above, the plastic film capacitor of the present invention is a plastic film capacitor in which a dielectric film 6 is laminated and wound around an electrode foil 2 to which a lead wire 1 is welded. The present invention is characterized in that a strip-shaped protective film 7, which can be easily bonded by low-temperature pressurization, is attached to the portion where the film 6 contacts the welded portion 5 of the lead wire 1. In conventional capacitors of this type, the protective film was heat-welded6 to the dielectric film, which deteriorated the dielectric film and resulted in defective products.Also, to prevent defective products from being produced, a thick film was used. By adopting this method, all of these problems will be resolved.
