壊する虞がある。゛ [Prior Art] Conventionally, in the manufacturing method of this type of wound capacitor, lead terminals are welded to predetermined positions on electrode foil made of aluminum or the like, and then the lead terminals are welded to a dielectric film such as plastic film. They are alternately layered and wound. However, usually, flashes are likely to occur in the welded portions of the lead terminals, and the flashes damage the dielectric film, lowering its dielectric strength, and in extreme cases, there is a risk that the insulation between the electrode foils may break down.
この対策として従来は、リード端子溶接位置の電極箔と
誘電体フィルムとの間に、誘電体フィルムよりも厚い絶
縁性の保護フィルムを介挿する方法が提案されている。As a countermeasure to this problem, a method has conventionally been proposed in which an insulating protective film, which is thicker than the dielectric film, is inserted between the electrode foil and the dielectric film at the lead terminal welding position.

電極９によって通電されてリード端子８が溶接される。That is, in the above-mentioned method for manufacturing a wound type capacitor, as shown in FIG. The sheets are run in the same direction, sandwiched between a pair of rollers 4.5, and alternately stacked, and wound around the winding core 3 to form a wound type capacitor. The electrode foil 1 is placed on the pedestal 6 together with the one node terminal 8 while traveling, and the lead terminal 8 is welded by being energized by the welding electrode 9.

disconnected by. The cut protective film 7 is drawn between the rollers 4.5 and wound while being sandwiched between the electrode foil 1 and the dielectric film 2 at the lead terminal welding position.

のコンデンサの信頼性を低下させる原因となっている。As mentioned above, in the conventional manufacturing method of wound type capacitors, the cut protective film is simply drawn between rollers and sandwiched between the electrode foil and the dielectric film, so the timing of cutting is limited. There is a possibility that the protective film may be misaligned in the longitudinal direction or curved depending on the winding speed or the like. If a long protective film is used in anticipation of the above-mentioned longitudinal positional deviation, the material cost will increase and the manufactured capacitor will also be large, and it is impossible to prevent the positional deviation with this method, which is a serious problem. In some cases, the protective film may fall off, which reduces the reliability of these types of capacitors.

Further, while the electrode foil 1 is running, its running is temporarily stopped and placed on a pedestal 6 made of an insulating material such as a quartz plate, and further between the electrode foil 1 and the pedestal 6. A protective film 7 made of heat-meltable insulating material such as plastic is inserted, and at the same time, the flat portion of the lead terminal 8 is placed on the electrode foil 1.

を得ることができる。As described in detail above, in the present invention, the protective film is welded to the welding position of the lead terminal of the electrode foil using the Joule heat generated during welding between the lead terminal and the electrode foil, so a special device for welding is required. The protective film can be reliably fixed in a predetermined position without requiring additional steps, and the protective film can be prevented from shifting, bending, or falling off. Moreover, since there is no need to use a long protective film in anticipation of longitudinal positional deviation of the protective film, the amount of materials used can be reduced. Therefore, according to the present invention, it is possible to obtain a wound type capacitor that is small and inexpensive without the risk of deterioration in reliability due to damage to the dielectric film caused by the welded portion of the lead terminal.
