Title:
CURRENT INTERRUPTING DEVICE AND ELECTRICITY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026455
Kind Code:
A1
Abstract:
This current interrupting device is provided with: a first conductive member connected to an electrode terminal; a second conductive member connected to an electrode; and a deformable member. The first conductive member has a center portion that is recessed from an end portion. The second conductive member is disposed facing the first conductive member side on which the recess is formed, said second conductive member being disposed by having a gap between the first conductive member and the second conductive member. An end portion of the deformable member is bonded to the first conductive member, and a center portion is in contact with the second conductive member. When the pressure in a case exceeds a predetermined value, the center portion of the deformable member moves to the first conductive member side by separating from the second conductive member, and the deformable member comes into contact with the center portion of the first conductive member.
