Although the present invention is not bound by any theory, fuse element of the present invention is considered to cut off overcurrent as under type.If flow through overcurrent in fuse element of the present invention, then produce Joule heat because of the intrinsic resistance of fuse cell.Due to this heat, first low-melting-point metal layer fusing, low-melting-point metal layer segment is fused.The fusing of low-melting-point metal layer is now relatively slower, but because the electric current meeting turn of tidal stream flowed here is to high melting point metal layer, so the generation of electric arc is inhibited.The electric current turn of tidal stream flowed in low-melting-point metal layer to high melting point metal layer as a result, the electric current that flows through high melting point metal layer is well beyond the independent rated current of high melting point metal layer, high melting point metal layer can be fused rapidly.Consequently, fuse element of the present invention cuts off overcurrent while suppression electric arc produces.
Invention effect
Fuse element of the present invention carries out by using the high melting point metal layer formed by refractory metal to major general and the low-melting-point metal layer formed by low-melting-point metal the fuse cell be laminated; for being not the overcurrent far exceeding rated current; the overcurrent of about 2 times of such as rated capacity, also can provide reliable protection.In addition, fuse element of the present invention can suppress the generation of electric arc when fusing.
