Document Type and Number:
WIPO Patent Application WO/2023/142946
Kind Code:
A1
Abstract:
The present application discloses a protection assembly (8), a battery (2) and an electrical device; the protection assembly (8) is applied to a switching apparatus (7) of the battery (2); the switching apparatus (7) comprises a conductive switching member (71); the protection assembly (8) comprises a main body portion (81), a protective cover (82) slidably connected to the main body portion (81), a connecting member (83) fixedly connected to the protective cover (82), and a limiting member (84) connected to the main body portion (81). The limiting member (84) is crimped to the connecting member (83), and the limiting member (84) can move vertically, allowing the connecting member (83) and the protective cover (82) to move along the direction in which the conductive switching member (71) extends, and the protective cover (82) at least partially covers one end of the conductive switching member (71). The protection assembly (8) of the present application reduces the probability that a conductive member of a component becomes exposed, and improves the safety performance of the battery.
