Shell assembly of button cell, button cell and electronic product

Abstract

The invention provides a shell assembly of a button cell, the button cell and an electronic product. The shell assembly of the button cell comprises a shell and a conductive part, the shell and the conductive part define an accommodating cavity for accommodating a battery cell of the button cell, the battery cell is provided with a first tab and a second tab; the first tab is electrically connected with the shell; and the second tab is electrically connected with the conductive part; the shell is provided with a through hole; the conductive part is arranged in the through hole in a penetratingmode; and a sealing rubber ring enabling the conductive part and the inner wall of the through hole to be sealed and insulated is arranged between the conductive part and the inner wall of the through hole. Wherein the shell comprises an upper shell with an opening in one end and a bottom cover for sealing the opening of the upper shell, a tab groove is formed in one surface of the bottom cover facing the battery cell , and at least part of the first tab is positioned in the tab groove and is connected with the tab groove, so that the sealing performance of the shell assembly of the button battery is improved.

Description
