Title
(EN) Button cell
(ZH) 纽扣电池
Abstract
(EN) The invention provides a button cell, which is characterized in that a bottom shell comprises a bottom wall and an enclosure wall bent and extended from the periphery of the bottom wall, and a cover body comprises a first shell directly facing the bottom wall, a second shell abutted against the surrounding wall and an insulating piece connecting the first shell and the second shell; the second shell comprises a first connecting part, a second connecting part, a third connecting part and a fourth connecting part which are connected in sequence. The first connecting part, the second connecting part, the third connecting part and the fourth connecting part are sequentially arranged on the second shell, the first connecting part is connected with the insulating piece, the second connecting part extends in the direction away from the bottom wall, the third connecting part extends parallel to the bottom wall, the fourth connecting part extends in the direction close to the bottom wall, the end of the enclosure wall abuts against the electric connecting part, the outer side of the enclosure wall is attached to the fourth connecting part, the third connecting part is fixedly connected withthe end of the enclosure wall, and thus the situation that the battery body is damaged due to shell deformation caused by high temperature in the welding process is avoided.
(ZH) 本发明提供了一种纽扣电池,底壳包括底壁以及自底壁周缘弯折延伸的围壁,盖体包括与底壁正对的第一壳体、与围壁抵接的第二壳体以及连接第一壳体和所述第二壳体的绝缘件;第二壳体包括依次相接的第一连接部、第二连接部、第三连接部及第四连接部。通过在第二壳体上一次设置第一连接部、第二连接部、第三连接部及第四连接部,第一连接与绝缘件连接,第二连接部向远离底壁方向延伸,第三连接部平行于底壁延伸,第四连接部向靠近底壁方向延伸,围壁端部与电连接部抵接且围壁的外侧部与第四俩接部贴合,第三连接部和围壁的端部固定连接,使得在焊接过程中不会因高温导致的壳体变形而破坏电池体。
