PROTECTION ELEMENT AND SECONDARY BATTERY DEVICE |
摘要 |
[Abstract] Provided are a protection element and a secondary battery device employing the protection element which is capable of stably retaining a flux on a soluble conductor at a predetermined position, enabling appropriate blowout of the soluble conductor in the event of an abnormality. This protection element has: a soluble conductor 13 which is disposed on an insulation baseboard 11; is connected to a power supply path of a device targeted to be protected; and the blowout at a predetermined abnormal electric power occurs; a flux 19 coated on a surface of the soluble conductor 13; and an insulation cover member 14 which is mounted on the baseboard 11, for covering the soluble conductor 13. The protection element comprises a protrusive stripe 20 forming a stepped portion 20a for retaining the flux 19 at a predetermined position in contact with the flux 19. The stepped portion 20a is formed in opposite to a center part of the soluble conductor 13 on an interior face of the insulation cover member 14. |
