Connection structure between battery cell electrode tab and cover plate

摘要

A connection structure for connecting a tab (7) of a cell with a cover board (1) comprising a tab (7) and a cover board (1) is provided. An insulating spacer (6) and an elastic conductive ring (5) are provided at an end of the cell (8). The tab passes through an orifice of the insulting spacer (6) and then is electrically connected with the elastic conductive ring (5) which is electrically connected with the cover board (1). An elastic pressing disc (4) may be further provided on the elastic conductive ring (5). The elastic conductive ring (5) is electrically connected with the cover board (1) via the elastic pressing disc (4). A staple (3) may be further provided on the elastic pressing disc (4) and the elastic conductive ring (5). The staple (3) has a slot (302) on one end for matching with an elastic hook (603) provided on the insulating spacer (6).
