Electric fuse-links and method of making them |
摘要 |
A fuse element for a cartridge fuse-link comprises a thin metal wire helically wound about a thin flexible core consisting of an electrically and heat insulating filament. Spaced sections of the winding at opposite ends of the fuse element are metallized so as to short-circuit the turns in these sections. The short-circuited sections are electrically interconnected by the active turns of an intermediate section which constitutes the fusible link. The fuse element is disposed in an insulating cartridge with its short-circuited sections connected to conductive end caps on the cartridge.
