Abstract
A quick-acting fuse comprising a fuse base encased within an insulated fuse cartridge. The fuse base consists of a lower insulating plastic (phenolic) plate and an upper conductive metal (copper) plate coextensively bonded to the lower plate. The fuse base has an enlarged mid-section of generally hexagonal or polygonal configuration which necks down on both sides to a pair of projecting arms whose ends are soldered to end caps used to seal the fuse cartridge when the fuse base is placed therein. The mid-section of the fuse has a generally elliptical hole and the upper metallic plate is partially etched away around said hole so as to provide a pair of spaced-apart and opposed conductive terminals. A pair of opposed grooves is provided, one at each end of said conductive terminals, and a fusible element is stretched between said grooves across said generally elliptical hole. A solder pool is provided next to each groove for quantitative soldering the ends of the fusible element.
