Fuse for high voltage electric circuit used in motor car, has straight conductor extended in form of straight line between main base and auxiliary base, and permanent magnet arranged to influence melting portion by magnetic field

摘要

The fuse (10) has a melting section (33) whose one end is connected with main base (35) and another end is connected with an auxiliary base (36). The main base is electrically connected with auxiliary base. A permanent magnet (40) which is ferrite magnet or a neodymium magnet is arranged to influence melting portion by a magnetic field. The north-south direction of permanent magnet is extended transversely to melting portion. A straight conductor is extended in the form of straight line between main base and auxiliary base.
