BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention relates to a blade type multielectrode fuse to be used mainly for automobiles which is characterized in that blowout portions and a plurality of terminals are formed integrally by punching from a long fuse material consisting of a single electrically conductive plate.
2. Description of the Related Art A fuse element which is disclosed by U.S. Patent No. 4023264 is conventionally known as a general fuse which is to be disposed in a fuse box for automobiles.
This fuse element is manufactured by sequentially punching with presses and cutting out from a long fuse material 12 which has a thin portion 11 of definite width formed at in a longitudinal direction at a middle portion thereof into a piece having a predetermined shape and a predetermined length, and configured as a bielectrode type fuse element which has a thin blowout portion 13 between a pair of right and left terminals as shown in FIGS.
7 and 8. In addition, a reference numeral 10 represents an insulating housing in which the fuse element is to be disposed and ffixed.
Further, a fuse element disclosed by Japanese Patent Publication (KOKOKU) No. 61-14625 is known as a multielectrode type fuse element which is configured to prevent a blown fuse from influencing on other: fuses by arranging a plurality of output terminals in parallel with an input terminal on a side of a power source by way of a blowout portion.
This fuse element is manufactured by punching from a long fuse metal plate material 14, and consists of a common link 16 and a plurality of fuse forming links 17, 17,... which are disposed on one side of a coupling link 15 so that they hang down in parallel with one another, and that they have blowout portions 18 which have sectional areas smaller than those of the other portions as shown in FIGS. 9 and 10.
