Title: Electric double layer capacitor
Inventor: WATANABE NORIYUKI
IPC: H01G11/10
Filed: 1989-04-27
Abstract: PURPOSE:To prevent secondary trouble such as an accident resulting in injury or death, the damage of a peripheral circuit, etc., by inserting a metallic foil, in which two circular sections having approximately the same diameter as the diameter of a capacitor element and holding an insulating sheet are connected by a narrow bridging section, at the approximately central position of laminating of a laminate. CONSTITUTION:The bridging section 7c of a metallic foil 7 is bent so as to cover both surfaces of an insulating disc 6, and two circular sections 7a, 7b are fast stuck. A part assembled in this manner is called a fuse 8. In a product under the state in which the fuse 8 is held and laminated at the approximately intermediate position of the laminate of an electric double layer capacitor element 5, currents are made to flow through the bridging section 7c of the metallic foil 7 when voltage is applied to the product. Accordingly, when overcurrents are made to flow, the bridging section 7c is melted, and continuity between the capacitors divided into two is interrupted by the insulating disc 6. Even when instantaneous overcurrents are made to flow, the electrolysis of an electrolyte is not advanced, thus preventing the blowoff of a gas.
