デンサを提供するものである。[Detailed description of the invention] This invention uses a metal case and a metal lid for the exterior and closes the impregnation holes with a hot-melt adhesive to eliminate the influence of the halogenated hydrocarbon solvent used as a cleaning agent and deteriorate the characteristics. In addition to preventing dangers such as explosions due to deterioration of characteristics, the hot-melt adhesive contains an irreversible temperature-indicating substance to identify the temperature applied to the capacitor and detect accidents and investigate characteristics. The present invention provides an electrolytic capacitor that can be easily manufactured.
従来たとえばリード線端子開一方向形電解コンデンサは

る溝７を形成して密封していた。Conventionally, for example, in a unidirectional electrolytic capacitor with open lead wire terminals, as shown in FIG.
was inserted into a rubber stopper 4, which was housed in a metal case 5, and then a winding portion 6 and a groove 7 formed by pressing were formed at the open end of the metal case 5 to seal it.
このような構成からなる電解コンデンサでは全体の大き
さの中に占めるゴム栓４の割合が大きく小形化の障害に
なっているばかりでなく、完成された電解コンデンサを
基板に組み込みハンダ付けしたのちハロゲン化炭化水素
系溶剤（たとえばトリクロルエチレン、メチルクロロホ
ルムなど）を用いてハンダフラックスなどの洗浄を行っ
ていた。In an electrolytic capacitor with such a configuration, the rubber plug 4 occupies a large proportion of the overall size, which is an impediment to miniaturization. Solder flux and the like were cleaned using hydrogenated hydrocarbon solvents (for example, trichloroethylene, methyl chloroform, etc.).

た。However, the halogenated hydrocarbon solvent is used between the metal case 5 and the rubber stopper 4, between the rubber stopper 4 and the lead-out terminals 2 and 3, and between the rubber stopper 4 and the rubber stopper 4.
In some cases, the metal penetrates into the capacitor and reacts with the aluminum electrode foil, causing corrosion and eventually breaking the wire.
またゴム栓４は天然ゴムや合皮ゴムを用いているか高温
領域や経時によって劣化し反発弾性を失い気密効果が低
下するとともに防爆弁を設けたものは硬度の変化によっ
てその機能を失ってしまい爆発の危険性が増大するなど
の欠点を有し、コンデンサの使用に際して加えられる温
度が実際に測定できない問題点があった。In addition, the rubber stopper 4 is made of natural rubber or synthetic rubber, which deteriorates in high-temperature areas or over time, loses rebound resilience, and reduces airtightness.Those with an explosion-proof valve lose their function due to changes in hardness and explode. This method has drawbacks such as an increased risk of oxidation, and the problem that the temperature applied when using a capacitor cannot actually be measured.
本考案は上記の点に鑑みてなされたもので金属ケースを
封目するゴム栓の代わりに含浸孔を有する金属蓋を用い
該含浸孔を非可逆性の示温物質を含む熱溶融性接着剤で
閉塞した構成からなるものである。The present invention was developed in view of the above points, and instead of the rubber plug that seals the metal case, a metal lid with impregnated holes is used, and the impregnated holes are filled with a hot-melt adhesive containing an irreversible temperature-indicating substance. It consists of a closed configuration.
したがってゴム栓を用いないので小形化できるとともに
ハロゲン化炭化水素系溶剤の浸入を防止できるから腐蝕

溶融性接着剤に含ませることによってコンデンサに加え
られた最高温度を知ることができるなどすぐれた特長を
有する電解コンデンサを提供するものである。Therefore, since a rubber stopper is not used, the size can be made smaller, and corrosion can be avoided since the penetration of halogenated hydrocarbon solvents can be prevented.Furthermore, by using an appropriate hot-melt adhesive, the impregnation hole can be opened at a desired set temperature. Electrolytic capacitors have excellent features such as there is no risk of explosion, and the maximum temperature applied to the capacitor can be determined by incorporating an irreversible temperature-indicating substance into the heat-melting adhesive. This is what we provide.

The capacitor element 13 can be impregnated by injection through the impregnation hole 18 provided in the capacitor element 5, or a pre-impregnated capacitor element 13 can be used. When inserting into the terminal 17, it is necessary to clean the lead terminal 11.12 and take into consideration the close contact with the above-mentioned insulator 19.20.
しかるのち前記含浸孔１８を非可逆性の示温物質を含む
