Vertical fuse

Abstract

The invention provides a vertical fuse which comprises a fuse tube body and a fuse body, a first containing cavity is formed in the fuse body, a first through hole and a second through hole are formed in the first end face of the fuse tube body, the first end face of the fuse body penetrates out of the first through hole to form a first electrode, and the second end face of the fuse body penetrates out of the second through hole to form a second electrode; the maximum diameter of the first end face of the fuse tube body and the maximum diameter of the second end face of the fuse tube body are both smaller than the length of the fuse tube body in the first direction. The first end face is parallel to the second end face, and the first direction is the direction from the first end face to the second end face or from the second end face to the first end face; the first accommodating cavity is filled with an arc extinguishing medium, and the arc extinguishing medium wraps the melt. Therefore, the electrodes are arranged on the same end face of the fuse tube body, so that the area of a fused mounting surface is reduced, the transverse projection area of the fuse in a circuit is further reduced, and the longitudinal space utilization rate of equipment is improved.
