Abstract

L'invention concerne des éléments d'obturation pour piles électriques. Une pile électrique étanche comporte une enveloppe tubulaire 11 qui est scellée, à une extrémité, par un obturateur 13 en matière plastique recouvert par un capuchon extérieur conducteur 15. L'obturateur 13 est moulé d'une seule pièce avec un bouchon auquel il est relié par un mince voile de matière plastique, s'étendant dans la direction longitudinale de l'enveloppe tubulaire 11 et pouvant se rompre afin de libérer le bouchon dans le cas de l'apparition d'une pression gazeuse excessive à l'intérieur de la pile. Domaine d'application : piles alcalines au manganèse, etc.The invention relates to sealing elements for electric batteries. A sealed electric cell comprises a tubular casing 11 which is sealed at one end by a plastic plug 13 covered by a conductive outer cap 15. The plug 13 is molded in one piece with a plug to which it is connected. by a thin veil of plastic material, extending in the longitudinal direction of the tubular casing 11 and capable of being ruptured in order to release the stopper in the event of the appearance of an excessive gas pressure inside the cell . Scope of application: alkaline manganese batteries, etc.
