Summary:The present invention relates to a cap assembly mounted on an open upper end of a cylindrical can of a battery having a structure in which an electrode assembly is embedded, comprising: a safety vent for discharging gas while rupturing when an internal pressure of the battery rises; an upward protruding cap plate mounted on an upper portion of the safety vent and having a through-hole for discharging the gas; a current breaking member attached to a lower end of the safety vent to interrupt an electric current when the internal pressure of the battery rises; and a guide member attached to the inside of the cap plate so as to prevent an escape of the ruptured part of the safety vent ruptured due to an increase in internal pressure of the battery. La présente invention concerne un ensemble capuchon monté sur une extrémité supérieure ouverte d'une boîte cylindrique d'une batterie comportant une structure dans laquelle est intégré un ensemble d'électrodes, comprenant : un évent de sécurité servant à évacuer le gaz lorsqu'il rompt lors de l'élévation d'une pression interne de la batterie ; une plaque de capuchon en saillie vers le haut montée sur une partie supérieure de l'évent de sécurité et comportant un trou traversant servant à évacuer le gaz ; un élément de coupure de courant fixé à une extrémité inférieure de l'évent de sécurité servant à couper un courant électrique lors de l'élévation de la pression interne de la batterie ; et un élément de guidage fixé à l'intérieur de la plaque de capuchon de façon à empêcher un dégagement de la partie rompue de l'évent de sécurité ayant rompu en raison d'une augmentation de la pression interne de la batterie. 본 발명은 전극조립체가 원통형 캔에 내장되어 있는 구조의 전지에서 캔의 개방 상단부에 탑재되는 캡 어셈블리로서, 전지의 내압 상승시 파열되면서 가스를 배출하는 안전벤트; 상기 안전벤트의 상부에 탑재되고, 가스 배출을 위한 관통구가 형성되어 있는 상향 돌출형의 캡 플레이트; 상기 안전벤트의 하단에 부착되어 있고, 전지 내압의 상승시 전류를 단전시키는 전류 차단부재; 및 전지의 내압 상승에 의해 파열된 안전벤트의 파열 부위가 이탈을 방지하기 위해 캡 플레이트의 내측에 부착되어 있는 가이드 부재;를 포함하고 있는 캡 어셈블리에 대한 것이다.
