The invention provides a circuit fuse box comprising a housing, conductive sheets, a fuse unit, and a wire. The conductive sheets, the fuse unit, and the wire are arranged inside the housing. The conductive sheets are connected to one end of the fuse unit; and the wire is connected to the other end of the fuse unit. In addition, the circuit fuse box also includes sealing elements arranged at the housing; one end of each conductive sheet is arranged inside the sealing element and the other end of the conductive sheet is arranged inside the housing. Besides, the circuit sealing structure includes a circuit fuse box consisting, sealing elements having through holes, electrical equipment, conductive bolts, and rubber caps; the conductive bolts and the rubber caps are connected with the electrical equipment electrically; and the conductive bolts pass through the through holes to realize electric connection between the conductive sheets in the sealing elements and the electrical equipment.
