Abstract

Cette invention a pour objet une structure d'accumulateur comprenant au moins deux cellules élémentaires disposées de façon axialement parallèle et de façon inversement parallèle de sorte que les broches d'électrode positive et négative sont orientées de façon inversée, des éléments d'isolation couvrant les cellules élémentaires respectives, et un élément de connexion servant à connecter la broche d'électrode positive d'une cellule élémentaire à la broche d'électrode négative de l'autre aux extrémités des cellules élémentaires. L'élément de connexion comprend une partie de connexion d'électrode négative, fixée à l'autre cellule élémentaire de telle sorte qu'elle est en contact avec la broche d'électrode négative de l'autre cellule élémentaire, et une barre omnibus dont une extrémité est raccordée à la broche d'électrode positive de ladite cellule élémentaire. La partie de connexion d'électrode négative possède une fente dans laquelle l'autre extrémité de la partie de barre omnibus est enfichée. L'autre extrémité de la partie de barre omnibus est chanfreinée de sorte que l'extrémité dans le sens du branchement de l'autre extrémité dans la fente ne peut pas endommager l'élément d'isolation. On obtient ainsi une amélioration de la sécurité de la structure d'accumulateur.
