A fuse for protecting battery and storage transportation safety

Abstract

This utility model discloses a fuse for battery protection and storage / transport safety, belonging to the field of battery short-circuit protection components. It comprises a battery compartment with a battery cover on top, where a pair of double-ended screws are mounted. A fuse is connected between these screws, featuring a narrow central section and a stepped width variation between the middle and ends. The fuse automatically melts when current exceeds its capacity, preventing cell damage from overload. It also melts during external short circuits to ensure battery safety and prolong service life. Removal is simple — just unscrew the hex nut—making it ideal for temporary use in transportation. This design enables zero-voltage storage and transport, and any damaged fuse can be replaced without affecting normal operation.
