Abstract
A blade fuse includes parallel blades (12 and 14) secured in a body (16). A fusible link (42) welded to the blades is located in a cavity (20) of the body that is covered by a window (61). The blade fuses are assembled by blanking the fusible element from a ribbon (90) and translating it into a fuse subassembly (64). Tabs (50 and 52) secure the fusible element in the subassembly (64) until it is spot welded to blades 12 and 14. The window (61) is then blanked and translated to cover cavity (20) and secured by ultrasonic welding. A connector strip (76) is then blanked from between blades (12 and 14) to provide the blade fuse.
