Abstract
A safety fuse for use in a motor vehicle includes which fuse comprises a first contact metal portion, a second contact metal portion and a melting metal section connecting the first contact portion to the second contact portion. The melting section is enclosed by a casing made from a non-conductive material and includes two hollow half-shells provided with mutual coupling elements, each half-shell having an inner surface facing the melting section and an outer surface facing outside of the fuse. At least one of the half-shells is provided on at least part of the inner surface of an alveolar structure with open cells in the direction of the melting section. The alveolar structure is formed by a plurality of walls protruding from the inner surface and intersected with each other.
