Fuse with stone sand matrix reinforcement

An electrical fuse comprising:

• a housing;
• first and second terminal assemblies coupled to the housing;
• at least one fuse element assembly extending internally in the housing and coupled between the first and second terminal assemblies;
• a filler material surrounding the at least one fuse element assembly in the housing, wherein the filler material comprises sodium silicate binder and sand and hardens into a stone sand matrix;
• and
• a reinforcing element suspended entirely within the stone sand matrix, a mixture of the filler material and the reinforcing element mechanically binding directly to the housing only through the sodium silicate binder, the reinforcing element structurally supporting the stone sand matrix and increasing a tensile strength of the stone sand matrix to limit cracking of the stone sand matrix caused by at least one of manufacturing imperfections, impact, and vibration of the electrical fuse in an electric vehicle, thus limiting arcing upon opening of the fuse, and thereby to increase reliability of the electrical fuse.
