Abstract:
1. A current fuse device comprising: an insulating box having a cavity; a first conductor fixed to the insulating box with a first outer end projecting out of the insulating box and a first inner end in the cavity; a second conductor fixed to the insulating box with a second outer end projecting out of the insulating box and a second inner end in the cavity, the second inner end of the second conductor opposing the first inner end of the first conductor; and at least one elastic member disposed on at least one of the first conductor and the second conductor and inside the cavity, the elastic member forming an electrical connection between the first inner end of the first conductor and the second inner end of the second conductor, wherein the elastic member has an elastic potential energy to break the electrical connection when a short circuit occurs, wherein a gap is formed between the first inner end of the first conductor and the second inner end of the second conductor, the elastic member has a first end being fixed to one of the first conductor and the second conductor and a second end being provided in the gap, and wherein the first inner end of the first conductor and the second inner end of the second conductor are formed into trapezoid shapes, the first conductor and the second conductor being disposed with short sides of the trapezoid shapes in parallel and opposing each other.
