Abstract

L'invention concerne un ensemble plaque de couvercle et un élément de batterie. L'ensemble plaque de couvercle comprend une plaque de couvercle (1) et un montant (2), le montant (2) étant monté sur la plaque de couvercle (1), et la dimension du montant (2) dans la direction longitudinale de la plaque de couvercle (1) étant supérieure à la dimension du montant (2) dans la direction transversale de la plaque de couvercle (1). On constate que la dimension du montant (2) dans la direction longitudinale de la plaque de couvercle (1) est supérieure à la dimension du montant (2) dans la direction transversale de la plaque de couvercle (1), ce qui permet de s'adapter à une plaque de couvercle (1) dont la longueur est supérieure à la largeur. De plus, dans un espace de plaque de couvercle limité, l'augmentation de la taille du montant (2) afin d'améliorer la capacité de passage de courant de celui-ci remplace les solutions à double ou multiples rivets précédemment conçues pour accroître cette capacité, ce qui permet de réduire les coûts. En outre, la surface inférieure d'un élément de rivetage (3) pour le montant (2) est pourvue d'évidements anti-déformation (33), ce qui permet d'améliorer la résistance à la déformation et d'optimiser encore davantage la planéité de l'élément de rivetage (3) et du montant (2) une fois rivetés. Par ailleurs, le montant (2) est pourvu d'un bossage (224) faisant saillie à partir de l'élément de rivetage (3), de manière à pouvoir être facilement positionné sur une barre omnibus externe.
