Abstract: An explosion-proof over-current protection element includes a fuse body, a ceramic shell, an explosion-proof layer, an arc-extinguishing layer, and a protection layer. The fuse body includes two electrodes and a fuse wire between the electrodes. The fuse body is integrally formed. The fuse wire is arranged within a cavity of the ceramic shell. The electrodes protrude from inside of the cavity toward outside of the cavity to contact an outer wall of the ceramic shell. The explosion-proof layer is arranged within the cavity and contacts a bottom surface of the cavity. The arc-extinguishing layer is arranged within the cavity and covers the fuse wire. The explosion-proof layer and the arc-extinguishing layer are made of different materials. The protection layer is arranged within the cavity. The arc-extinguishing layer is located between the explosion-proof layer and the protection layer.

The low-melting-point metal plate has a first main surface, a second main surface, a first side surface, and a second side surface. The first main surface and the second main surface face each other. The first side surface and the second side surface face each other and each connect the first main surface and second main surface. The first high-melting-point metal layer is disposed on the first main surface and second main surface. The second high-melting-point metal layer is disposed on the first side surface and second side surface. The fuse element has a cut-out portion in which at least a portion of the second high-melting-point metal layer is cut out.

Abstract: A protective element includes a fuse element, a movable member, a concave member, and a press. The fuse member includes, a first end, a second end, and a cut part positioned between the first end and the second end. The fuse element is energized in a first direction from the first end to the second end. The movable member and the concave member are disposed facing each other such that the cut part is interposed therebetween. The press applies a force to the movable member in a pressing direction in which a distance between the movable member and the concave member shortens. At a temperature at or above a softening temperature of the fuse element, the cut part is cut by the force of the press.
