Abstract
An electrical fuse comprises a fusible conductor welded or bonded onto separated contact surfaces. The fusible conductor is coated with a metal, selected solely for optimum welding or bonding to contact zones of the contact surfaces. The metallic coating of the fusible conductor is then removed at the fusible portion of the coated fusible conductor by etching after the fusible conductor is welded or bonded to the contact surfaces the contact zones surrounding the point of contact protected by a resin cover resistant to the etchant. The electrical characteristic of the fuse is thus determined solely by the core wire and its properties. The resin cover in the contact zones is preserved between the fusible conductor and each contact surface for improved safety against cracks or micro-cracks and their possible adverse effects.
