A filler surrounds the at least one fuse element assembly, and the filler includes sodium silicate sand and at least one reinforcing structure suspended within the filler.

A fuse may include a leadframe including a first terminal having a first end and a second end, and a second terminal having a first end and a second end. A bridge may connect the respective second ends of the terminals. The bridge may have one or more protrusions disposed between the terminals and may be extended from the bridge. A base may have first and second apertures, and the first and second terminals may be at least partially disposed into the respective first and second apertures.

The heat locking hole of the connecting part can reduce a diffusion speed of heat of the connecting part, so that the heat is concentrated between the first heat locking hole and the second heat locking hole, and thus the connecting part can be fused in time at a high temperature.

A fuse element includes a low-melting-point metal plate, a first high-melting-point metal layer, and a second high-melting-point metal 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.
