この発明は、電解コンデンサの内圧上昇による
爆発を防止する電解コンデンサの防爆構造に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an explosion-proof structure for an electrolytic capacitor that prevents an explosion due to an increase in the internal pressure of the electrolytic capacitor.
電解コンデンサは、その構造上、動作電流によ
つて水素ガスを発生するものであるが、大電流
（過電流）が流れると、その水素ガスの発生が顕
著になり、その水素ガスによる外装ケースの内圧

る。
Due to its structure, electrolytic capacitors generate hydrogen gas due to the operating current, but when a large current (overcurrent) flows, the generation of hydrogen gas becomes noticeable, and the outer case is damaged by the hydrogen gas. There is a risk of explosion due to increased internal pressure.
このため、電解コンデンサでは、急激な内圧上
昇による爆発を防止するために防爆構造が取られ
ているが、この防爆構造には、外装ケースの底面

状を成す防爆弁を形成し、後者の例としては、第
７図に示すように、電解コンデンサ素子２を収容
した外装ケース４の封口体６に防爆弁８を形成す
るものである。 For this reason, electrolytic capacitors have an explosion-proof structure to prevent explosions caused by a sudden increase in internal pressure. There are things that form. As an example of the former, when the exterior case is made of aluminum or the like, a V-shaped explosion-proof valve that can be opened by a specific pressure is formed on the bottom of the case, and as an example of the latter, as shown in Fig. 7. As shown, an explosion-proof valve 8 is formed in a sealing body 6 of an exterior case 4 housing an electrolytic capacitor element 2.
ところで、封口体６に設けられる防爆構造は、
封口体６にゴムなどの弾性材料が用いられるの
で、その素材の持つ弾性を利用し、圧力作用で開
口可能な部分を形成するものであり、たとえば、
第８図に示すように、封口体６の成形加工と同時

４とともに、その内部に薄肉部１６を形成して防
爆弁８とするものである。
By the way, the explosion-proof structure provided in the sealing body 6 is as follows.
Since an elastic material such as rubber is used for the sealing body 6, the elasticity of the material is utilized to form a portion that can be opened by the action of pressure.
As shown in FIG. 8, simultaneously with the molding process of the sealing body 6, an explosion-proof hole 1 is formed in the sealing body 6 using the molds 10 and 12.
4 and a thin wall portion 16 is formed inside thereof to form an explosion-proof valve 8.
このような金型１０，１２によつて成形された
薄肉部１６の寸法d1の精度は、金型１０，１２の
成形時の間隔および成形圧力などの成形要素につ
いての精度を高めても、封口体６を成す弾性材料
自体の弾性による逃げが大きく影響するため、開
口径d2の寸法精度に比較して低く、金型精度の調
整だけでは、逃げによる誤差を吸収することがで
きないのである。たとえば、防爆弁８を成す薄肉
部１６の厚さを0.4mmに設定した場合、その誤差
は±0.2mmにも達するものであり、これは、防爆
弁８の動作圧力が誤差によつて0.25〜2.25倍の幅
を持つて変動することになり、適正な開弁動作が
得られないおそれがあつた。 The accuracy of the dimension d 1 of the thin wall portion 16 formed by such molds 10 and 12 remains unchanged even if the precision of molding elements such as the interval and molding pressure during molding of the molds 10 and 12 is increased. Since the relief due to the elasticity of the elastic material itself that forms the sealing body 6 has a large effect, it is lower than the dimensional accuracy of the opening diameter d2 , and the error due to relief cannot be absorbed only by adjusting the mold accuracy. . For example, when the thickness of the thin wall portion 16 forming the explosion-proof valve 8 is set to 0.4 mm, the error reaches as much as ±0.2 mm, which is because the operating pressure of the explosion-proof valve 8 varies from 0.25 to This resulted in fluctuations with a width of 2.25 times, and there was a risk that proper valve opening operation could not be obtained.
そして、素材の持つ弾性による成形時の逃げ
は、弾性材料や温度によつても影響を受けるの
で、薄肉部１６の動作特性が均一にならず、その
ため開弁動作が区々になり、封口体６側での防爆
構造は、信頼性に欠けるという欠点があつた。 The escape during molding due to the elasticity of the material is also affected by the elastic material and temperature, so the operating characteristics of the thin walled portion 16 are not uniform, and as a result, the valve opening operation becomes uneven, and the sealing member The explosion-proof structure on the 6th side had the drawback of lacking reliability.
そこで、この発明は、弁部分の寸法精度を高め
て動作特性の均一化を図り、信頼性の高い防爆構
造を得ようとするものである。 Therefore, the present invention aims to improve the dimensional accuracy of the valve portion, to make the operating characteristics uniform, and to obtain a highly reliable explosion-proof structure.
