Abstract
A board fuse includes an insulating board having a through-hole window in the middle of the insulating board and fusible elements laid over the insulating board. Further, the fusible elements are continuous metal wires substantially equal in cross section. The fusible elements are uniform and accurate in cross section and accurate in current capacity. The fusible elements extend across the window in such a manner that, at the window, they are not in contact with the insulating board. Hence, when heat is generated in any one of the fusible elements by electric current, the heat generated at the window is not absorbed by the insulating board and is increased as required, thus blowing the fusible element accurately. Accordingly, the board fuse is free from the difficulties caused by the heat generation, that is, the production of a bad smell, at worst the production of white smoke.
