Problems solved by technology

[0005] However, when the fuse element has a wavy shape, the distance between a plurality of fuse portions provided on the fuse element then becomes short, and there is a problem that fuse portions close to each other exert an electric or thermal effect on each other, and fusing characteristics deteriorate
In addition, since the fuse element is bent like a wave, it is easy to cause deformation of the fuse element due to the action of external force etc. in the manufacture of the fuse
Therefore, there are problems that it is difficult to stabilize the position and orientation of the fuse element in the case, and the fusing characteristics are lowered

Abstract

The present invention provides a fuse that has stabilized fusing characteristics and that is easy to manufacture. A fuse 600 provided between a pair of terminal parts 110, the fuse 600 comprising a fuse element 100 having a plurality of fusing parts 120, and a casing 200 that accommodates the fusing parts 120, wherein the fuse 600 is characterized in that: the fuse element 100 has a bent shape along the length direction P of the fuse element 100, and comprises a first flat surface 140 and a second flat surface 150 that extend in linearly along the length direction P; the plurality of fusing parts 120 are provided to the first flat surface 140 and the second flat surface 150; and the first flat surface 140 and the second flat surface 150 are continuous with each other in a bent section 131.

Description

technical field [0001] The present invention mainly relates to a fuse used in an electric circuit of an automobile or an electric circuit of infrastructure, etc., and more particularly relates to a fuse containing a fuse element in a housing. Background technique [0002] Conventionally, fuses have been used to protect electrical circuits installed in automobiles, infrastructure, etc., and various electrical components connected to the electrical circuits. More precisely, when an unexpected overcurrent flows in the circuit, the fusing part of the fuse element built in the fuse is blown by the heat generated by the overcurrent, thereby protecting each circuit by preventing excessive current from flowing. electrical components. [0003] Furthermore, there are various types of such fuses depending on applications, for example, a considerably large fuse for preventing overcurrent disclosed in Patent Document 1 is known. [0004] The fuse disclosed in Patent Document 1 is of th...
