IMPROVED MINIATURE ELECTRIC FUSE Abstract of the Disclosure A miniature electric fuse having variable thermal capacity and improved arcing characteristic comprising a fuse base and body, a fuse cover and a pair of electrically conductive terminals protruding from the fuse base and partially embedded into the fuse body. The fuse body comprises a pair of opposed, spaced apart generally crescent-shaped members, each member being defined by an outer curved surface, generally flat top and bottom surfaces and a generally perpendicular inner wall, wherein each of said inner walls is spaced apart and is in parallel facing rela- tion to one another. The embedded ends of the electrically con- ductive terminals are disposed midway in each of the respective members of the fuse body. A groove is cut in each of said mem- bers from their top surfaces to midway in said members and thereafter angled horizontally relative to the inner walls of said members. A fusible element is stretched between said ter- minals and has its end portions resting on the bottom of said grooves and are soldered thereto. A metal plate which may vary in thickness is placed upon the solder in intimate contact there- with for improved thermal capacity.
