Title (EN) BUTTON TYPE CAN AND BUTTON CELL
(FR) BOÎTIER DE TYPE BOUTON ET PILE DE TYPE BOUTON
(ZH) 纽扣式壳体及纽扣电池
Abstract:
(EN) The present invention relates to a button cell, comprising a first-pole can, a second-pole can, an insulating and sealing ring, and a battery core. The first-pole can, the second-pole can, and the insulating and sealing ring together form an accommodation cavity, and the battery core is inside the accommodation cavity. The second-pole can comprises a body and a folding edge bending and extending downwardly from a periphery of the body. The insulating and sealing ring comprises a main component and an inner bend component extending inward from the main component. The main component is sandwiched between the folding edge of the second-pole can and the first-pole can, and the inner bend component is located below the folding edge, and an end face of the inner bend component does not extend beyond an inner side face of the folding edge of the second-pole can. The present invention also relates to a button type can. The invention enhances the stability of an internal structure of the button cell and improves the sealing property of the insulating and sealing ring by modifying the structure of the insulating and sealing ring without occupying an inner space of the second-pole can while improving the battery capacity.
(FR) La présente invention concerne une pile de type bouton, comprenant un boîtier de premier pôle, un boîtier de second pôle, un anneau d'isolation et d'étanchéité, et un noyau de batterie. Le boîtier de premier pôle, la boîtier de second pôle et l'anneau d'isolation et d'étanchéité forment ensemble une cavité de réception, et le noyau de batterie est à l'intérieur de la cavité de réception. Le boîtier de second pôle peut comprend un corps et un bord pliant se courbant et s'étendant vers le bas à partir d'une périphérie du corps. L'anneau d'isolation et d'étanchéité comprend un composant principal et un composant de courbure interne s'étendant vers l'intérieur à partir du composant principal. Le composant principal est pris en sandwich entre le bord pliant du boîtier de second pôle et le boîtier de premier pôle, et le composant de courbure interne est situé au-dessous du bord pliant, et une face d'extrémité du composant de courbure interne ne s'étend pas au-delà d'une face latérale interne du bord pliant du boîtier de second pôle. La présente invention porte également sur un boîtier de type bouton. L'invention améliore la stabilité d'une structure interne de la pile de type bouton et améliore la propriété d'étanchéité de l'anneau d'isolation et d'étanchéité en modifiant la structure de l'anneau d'isolation et d'étanchéité sans occuper un espace interne du boîtier de second pôle, tout en améliorant la capacité de la batterie.
(ZH) 本发明涉及一种纽扣电池,包括第一极壳、第二极壳、绝缘密封圈和电芯,第一极壳、第二极壳和绝缘密封圈共同形成容置腔,电芯在所述容置腔内,第二极壳包括本体和由本体的周缘向下弯折延伸的折边,所述绝缘密封圈包括主体部和由主体部向内延伸的内弯部,所述主体部夹置在所述第二极壳的折边与所述第一极壳之间,所述内弯部位于所述折边的下方且所述内弯部的端面不超过所述第二极壳的折边的内侧面。本发明还涉及一种纽扣式壳体。本发明通过对绝缘密封圈的结构进行改善,不占据第二极壳的内部空间,在提高容量的同时还加强了纽扣电池内部结构的稳定性,并且提高了绝缘密封圈的密封性。
