Abstract

The utility model discloses a protective device of a storage battery fuse, which comprises a connecting plate, and the other side of the connecting plate is provided with a connecting column. A fuse, a copper nose and an insulating part are sleeved on the connecting column, and the connecting column is connected with the connecting column through a fastener, so that the fuse, the copper nose and the insulating part are fixed on the connecting column. The insulating piece comprises a base plate and an isolation part installed on the base plate, and the isolation part is sleeved on the connecting column so as to achieve insulation between the copper nose and the connecting column. In conclusion, the fuse is utilized to realize connection or disconnection of a circuit between the copper nose and the storage battery, so that the damage to the storage battery caused by short circuit can be reduced while the smoothness of the circuit is ensured. On the basis, although the equipment is simple in structure, the fuse is convenient to replace while the safety of the circuit is ensured; particularly, the isolation part can completely isolate direct contact between the connecting column and the copper nose, so that generation of electric arcs between the connecting column and the copper nose is avoided.
