Abstract
A protective element includes a fuse element, a movable member, a concave member, and a press. The fuse member includes, a first end, a second end, and a cut part positioned between the first end and the second end. The fuse element is energized in a first direction from the first end to the second end. The movable member and the concave member are disposed facing each other such that the cut part is interposed therebetween. The press applies a force to the movable member in a pressing direction in which a distance between the movable member and the concave member shortens. At a temperature at or above a softening temperature of the fuse element, the cut part is cut by the force of the press.
Claims17
A protective element, comprising:
- a fuse element comprising a first end, a second end, and a cut part positioned between the first end and the second end, the fuse element being energized in a first direction from the first end to the second end;
- a movable member and a concave member disposed facing each other such that the cut part is interposed therebetween;
- a press to apply a force to the movable member in a pressing direction in which a distance between the movable member and the concave member shortens;
- a heating member comprising a resistor, having a plate shape, and disposed either contacting or near the cut part on a press side or a concave member side of the fuse element;
- and
- an electrical supply member connected to the resistor, the resistor of the heating member being heated by being energized through the electrical supply member,
- wherein the heating member is configured to be energized to directly heat the fuse element to a temperature at or above a softening temperature of the fuse element such that the cut part of the fuse element is softened and the force of the press cuts the cut part of the fuse element and a connection between the resistor and the electrical supply member.
