Abstract

L'invention concerne une batterie à électrode positive et électrode négative faciles à assembler et à montage étanche. Une pointe saillante positive (21) disposée à l'extrémité avant d'un corps de batterie (51) est pourvue de trois cercles de bagues convexes élastiques (14), et d'une manière correspondante, un capuchon d'extrémité négative (13) à l'extrémité arrière du corps de batterie (51) est pourvu d'une rainure (15). Trois rainures annulaires concaves (16) sont disposées dans la rainure (15). Le bord du capuchon d'extrémité négative (13) est pourvu d'une partie de prolongement cylindrique de batterie (17). Les trois cercles de bagues convexes élastiques (14) disposées sur la pointe saillante positive (21) sont des bagues convexes en caoutchouc élastique. La stabilité de montage bout à bout de la batterie est améliorée, et l'absence de survenue d'un mauvais contact est assurée dans l'utilisation de la batterie ; les performances d'étanchéité sont améliorées, et l'efficacité d'utilisation de la batterie n'est pas réduite en raison de l'intrusion de matières étrangères comme de la poussière extérieure vers l'électrode positive et l'électrode négative.
