Abstract
A subminiature fuse has a housing in which more than one enclosed arc-extinguishing chambers are in series provided with partitions inbetween and one or more than one small hole communicating with the more than one arc-extinguishing chambers in series are provided at the respective partitions, a pair of lead terminals being fixed to the housing in such a manner as the respective fuse wire connecting portions of the lead terminals are accommodated in the respective opposite end arc-extinguishing chambers and the portions of a pair of lead terminals for connection with an external circuit are projected out of the housing, a fuse wire being extended between the fuse wire connecting portions of the pair of lead terminals through the small hole of the respective partitions, the opposite ends of the fuse wire being electrically and mechanically connected respectively to the pair of the lead terminals, whereby the fuse is capable of providing a high breaking characteristics and quickly melting to sever the fuse wire upon flow of over-current without using arc-extinguishing material and causing less variation in the fusion time.
