Top-cover assembly, battery, and electricity-consumption device

Abstract

A top-cover assembly (100), a battery (200), and an electricity-consumption device (300) are provided. The top-cover assembly (100) includes a lower plastic member (30), a first terminal-post (41), and a first connecting sheet (50) extending linearly in a width direction of the top-cover assembly (100). The lower plastic member (30) includes a lower-plastic-member body (31). The lower-plastic-member body (31) defines a first through-hole (313) extending through the lower-plastic-member body (31) and allowing for the first terminal-post (41) to pass through. The first connecting sheet (50) is connected to the first terminal-post (41). The first connecting sheet (50) is configured to be welded to a first tab of an electrode assembly (220), to enable the first terminal-post (41) to be electrically connected to the electrode assembly (220) through the first connecting sheet (50). The first connecting sheet (50) is stacked with the lower-plastic-member body (31). A centerline (O1) of the first connecting sheet (50) in a length direction of the top-cover assembly (100) is offset from a centerline (O2) of the first terminal-post (41). Fig 10.
