閉されている。 Generally, in capacitors, such as aluminum electrolytic capacitors, electrode foils are used, which are made by etching aluminum foil with a thickness of 30 to 100 μm with an electrolyte containing mainly hydrochloric acid to form an oxide film in the electrolyte with a chemical conversion effect. . As shown in Figures 5 and 6, the structure is as follows: These electrode foils are caulked with lead-out leads, connected by welding, etc., and the two electrode foils are wound so as to face each other through electrolytic paper.
A capacitor element 1 is formed by impregnating it with a driving electrolyte, and then the drawer lead plate 7 of the capacitor element 1 is caulked to a sealing plate 10 made of a rubber-clad laminate or the like to which terminals 2 are fixed in advance and connected by welding or the like. It is housed in a bottomed cylindrical case 9 made of aluminum, and the open end of the case 9 is sealed tightly.

The lead plate 7 must be made longer than the radius of the sealing plate 10, and the impedance of the capacitor at high frequencies becomes large.
In addition, since the drawer lead plate 7 is long, it is easy to short circuit with the electrode foil when folded and assembled as shown in Fig. 6. To prevent this, the margin width of the electrolytic paper must be designed wide, and the overall length There were problems such as the size of the parts becoming large and the assembly being difficult to automate.

特徴とするコンデンサの製造方法である。Means for Solving the Problems In order to solve the above problems, the present invention fixes a terminal to a sealing plate, connects the terminal to a lead plate led out from a capacitor element, and stores the terminal in a case with the capacitor element. In a capacitor in which a sealing plate is fitted into the opening of the case and sealed by winding, a recess is formed inside the central part of the sealing plate, and the lead plate and the terminal are connected in the recess. This method of manufacturing a capacitor is characterized in that, in addition to arranging the connecting portions, the sealing plate is warped into a dish shape and the lead plate is connected to the capacitor, and then returned to its original shape and seamed.
作 用

でき、組立の自動化が容易に実現できる。Function Since the sealing plate with the concave portion is easily warped into a dish shape and the lead lead plate is connected in the deformed state, the length of the lead lead plate can be shortened, so the impedance of the capacitor at high frequencies can be significantly reduced. Automation of assembly can be easily achieved.

As shown in FIG. 3, the sealing plate 3 is warped into a dish shape, and the lead plate 7 led out from the capacitor element 1 is connected to the rivet 6 using a washer 8 by crimping, welding, or the like. Thereafter, as shown in FIG. 1, the sealing plate 3 which has been warped into a dish shape is returned to its original state and stored in the case 9, and the sealing plate 3 is fitted into the opening of the case and sealed by spooling. The above-mentioned sealing plate 3 is provided with a recess 4 having a concave cross-sectional shape in the center, so by pressurizing the center on the outside (on the elastic plate side), it can be easily sealed as shown in Fig. 3. Since it can be warped into a dish shape, assembly work can be easily automated.

There is also no risk that the lead plate 6 or the lead plate 7 will be short-circuited.
