Abstract
Provided is a fuse device used for high rating and high current applications excellent in impact resistance at the time of current interruption, and capable of preventing falling off of the case. The fuse device includes: a base member; a cover member fitted to the base member and covering a surface of the base member; and a fuse element mounted on the surface of the base member; wherein one of the base member and the cover member is provided with a side wall intersecting with the plane of the surface of the base member and including an opening formed therein, and the other of the base member and the cover member is provided with a fitting projection projecting outward from a plane intersecting with the plane of the surface of the base member and fitted into the opening of the side wall.
Claims11
A fuse device comprising:
- a base member:
- a cover member fitted to the base member and covering a surface of the base member, wherein the surface defines a plane;
- and
- a fuse element disposed between the base member and the cover member;
- wherein one of the base member and the cover member is provided with a side wall intersecting with the plane of the surface of the base member and including an opening formed therein, and the other of the base member and the cover member is provided with a fitting projection projecting outward from a plane intersecting with the plane of the surface of the base member and fitted into the opening of the side wall,
- the fitting projection is provided with a fitting claw which bulges in a direction intersecting the direction of insertion into the opening;
- the cover member and the base member are configured such that they slide in opposite direction along the plane of the surface when being fitted together;
- and
- the opening is provided with a protruded surface for locking the fitting claw.
