Document Type and Number:
Japanese Patent JP2637846
Kind Code:
B2
Abstract:
A fuse for handling normal load currents substantially in excess of about 80 amps, the fuse comprising a metal portion formed of an integral piece of metal having outermost, spaced terminal-forming portions with bolt-anchoring holes therein and a fuse link-forming intermediate portion between the terminal-forming portions. The terminal-forming portions of the metal piece has a rectangular configuration having inner margins spaced from one another. The fuse link-forming portion of the metal piece has an S-shape with one face thereof being co-planar with one of the faces of the terminal-forming portions thereof. The thickness of the S-shaped fuse link is only a fraction of the thickness of the terminal thickness and has outermost legs respectively extending from the opposite sides of the innermost margins of the terminal-forming portions of the metal piece and a central link interconnecting the outermost legs. The central leg has two pairs of spaced notches between which a tin pellet is anchored in an aperture to reduce the melting temperature of the fuse link so that prolonged overload currents will open the fuse link.
