Title
(EN) SEALING PLATE, CELL USING THE SEALING PLATE, AND METHOD OF MANUFACTURING THE CELL
(FR) PLAQUE D'ETANCHEITE, CELLULE UTILISANT CETTE PLAQUE ET PROCEDE DE FABRICATION DE CETTE CELLULE
Abstract
(EN)
A sealing plate used for cell, comprising a filter, a cap, and a valve disc, the filter further comprising a valve hole and an upper opening and the cap further comprising a projected part and a flange part provided around the projected part, wherein the opening end of the upper opening of the filter comprises a bent part and the outer peripheral end part of the flange part of the cap and the bent part comprise a crimped part connected to each other by crimping, the crimped part having both contact portions where the surface of the outer peripheral end part of the flange part is in contact strongly with the bent part and in contact weakly with the bent part, whereby an electrical contact resistance between the cap and the filter is reduced remarkably and stabilized at a low level, and the internal resistance of the cell is lowered so as to improve cell characteristics.
(FR)
L'invention porte sur une plaque d'étanchéité utilisée pour une cellule et comprenant un filtre, un couvercle et un disque de soupape. Le filtre comprend également un trou de valve et un orifice supérieur, le couvercle comprenant une partie saillante autour de laquelle est formée un rebord. L'extrémité de l'orifice supérieur du filtre comprend une partie courbe et l'extrémité périphérique externe du rebord du couvercle et de la partie courbe comprend une partie sertie raccordée à l'autre partie par sertissage. La partie sertie comporte à la fois des parties de contact où la surface de l'extrémité périphérique externe du rebord est la fois en contact étroit et en léger contact avec la partie courbe. Une résistance de contact électrique placée entre le couvercle et le filtre est considérablement réduite et stabilisée à un niveau inférieur, la résistance interne de la cellule étant réduite afin d'améliorer ses caractéristiques.
