Title:
CURRENT BREAKING DEVICE AND POWER STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/064777
Kind Code:
A1
Abstract:
This current breaking device is provided with a first current-carrying member, a second current-carrying member, and a deformable member. The first current-carrying member is connected to an electrode terminal. The second current-carrying member is connected to an electrode. The second current-carrying member is spaced away from the first current-carrying member and disposed so as to face the first current-carrying member. The second current-carrying member also has a recess formed therein on the side facing the first current-carrying member. The deformable member is disposed between the first current-carrying member and the second current-carrying member. Ends of the deformable member are joined to the first current-carrying member. When the pressure inside a case is not more than a prescribed value, a central part of the deformable member gets connected to the second current-carrying member within the recess of the second current-carrying member so as to cause conduction between the first and second current-carrying members. In addition, when the pressure inside the case exceeds the prescribed value, snap-buckling takes place in the deformable member so as to bring the first and second current-carrying members into a nonconductive state.
