あった。Problems to be Solved by the Invention In such a conventional sealing method for an aluminum electrolytic capacitor, the capacitor body is placed in an aluminum case 1.
In order to smoothly house the aluminum case 1 and improve productivity, it was necessary to provide a gap between the aluminum case 1 and the sealing body 2.

ミックコンデンサよりも耐熱性向上のための改善が必要
である。Furthermore, as electronic components tend to become lighter, thinner, shorter, and smaller, there is also a strong demand for heat resistance and wash resistance. Aluminum electrolytic capacitors are no exception, and since aluminum electrolytic capacitors in particular use a liquid electrolyte, they require more improvements in heat resistance than other capacitors, such as tantalum solid electrolytic capacitors and ceramic capacitors.
また、各種の電子部品がプリント基板に半田付けされた
後、有機塩素化物によって洗浄されるため。Also, after various electronic components are soldered to printed circuit boards, they are cleaned with organic chlorides.
耐洗浄性の改善も必要であるが、上述の方法によるアル
ミニウム電解コンデンサでは、これらの要求を十分満足
させることができないものであった。It is also necessary to improve the wash resistance, but the aluminum electrolytic capacitors produced by the method described above cannot fully satisfy these demands.
本発明はこのような現状に鑑みなされたもので。The present invention was made in view of the current situation.
封口性を改善することを目的とする。The purpose is to improve sealing performance.

て圧入する。Means for Solving the Problems In order to solve these problems, the present invention constructs a capacitor element by incorporating a sealing body having an outer diameter larger than the inner diameter of the metal case into the capacitor element. Then, the capacitor body is press-fitted while reducing the pressure inside the metal case. When press-fitting, press-fit through a press-fit funnel.

ように減圧しながら封口するものである。In this case, the inner diameter of the press-fitting funnel should be set to 0.06 to 0.161 smaller than the inner diameter of the metal case at the smallest point, and the pressure should be reduced and sealed so that the internal pressure of the metal case in the finished product would be below atmospheric pressure. It is something to do.
