Abstract
The present invention relates to a multistage fuse, and more particularly, to a multistage fuse including: a fuse module including a first fuse bar formed in a bar shape as a conductive member; a melted portion which supports the first fuse bar and is melted when overcurrent flows; and a second fuse bar which supports the melted portion; and a contact terminal which contacts the first fuse bar by elastic force, in which when the overcurrent flows on the melted portion, the melted portion is melted to disconnect the first fuse bar and the contact terminal.
Claims5
A multistage fuse comprising:
- a plurality of fuse modules aligned in a first direction, each fuse module including a first fuse bar formed in a bar shape as a first electrically conductive member;
- a meltable portion which supports the first fuse bar and is melted when overcurrent flows;
- and a second fuse bar which supports the meltable portion;
- and
- a contact terminal which contacts the first fuse bar of a given fuse module by elastic force,
- wherein when the overcurrent flows on the meltable portion, the meltable portion is melted to disconnect the contact terminal from the first fuse bar of given fuse module, and the elastic force pushes the contact terminal in the first direction towards a next fuse module.
