Abstract

A casing assembly, a battery cell, a battery, and an electric apparatus are disclosed. The casing assembly includes a casing and a sealing assembly. The casing has a through hole, and the sealing assembly seals the through hole. The sealing assembly includes an insulating member that covers a conductive member. The conductive member includes a first contact portion and a second contact portion. A connecting member with a hollow inner cavity is connected to the casing, and the insulating member fills the inner cavity. The first contact portion is located on the inner side of the casing, and the second contact portion is located on the outer side. This structure allows the sealing assembly to block the through hole and helps prevent electrolyte leakage, thereby enhancing the sealing performance of the casing.
