ABSTRACT:
The high speed fuse employs stamped end bell and terminals rather than forged or machined parts. A slot for the terminal is punched through the end bell. The terminal is inserted into the slot in the end bell and staked in position. This insures a strong tight fit without requiring welding or soldering. One end of each terminal has coined ridges to facilitate automatic welding of the fuse link to the terminals. Round balls are used to seal the fill holes for the arc quenching material. Metal pins secure the end bells within the fuse housing but are not electrically connected to the terminals because of the insulative end bells.
