Abstract
An electrically conductive metal plate is stamped out to yield a fuse unit including an input terminal and several output terminals. The fuse unit further includes a predetermined locus where fuse element portions are to be formed later. A surface area of the fuse unit including the predetermined locus is then molded with an insulator material. Thereafter, the fuse element portions are formed at the predetermined locus by, for example, stamping. In this manner, the fuse unit can be manufactured easily at low costs, irrespective of the number and electrical capacity of the fuse element portions.
Claims3
A fuse unit comprising an electrically conductive plate including an input terminal, at least one output terminal and at least one fuse element portion linking said input terminal and said at least one output terminal, each of said input terminal, said at least one output terminal and said at least one fuse element portion being formed unitarily and in one piece in said conductive plate, said fuse unit further comprising an area molded with an insulator material, said area including at least one opening through which a portion of said conductive plate is exposed to an outside of said insulator material for formation of said at least one fuse element portion through said at least one opening.
