Abstract
A switch device capable of safely opening an electrical circuit in response to an abnormality such as wetting with water or liquid leaking from a battery. The device includes a first conductor connected to an external circuit and having a relatively high ionization tendency, and a second conductor arranged close to the first conductor and having a relatively low ionization tendency which is lower than that of the first conductor, a reaction part which electrically corrodes the first conductor is formed by a liquid between the first and second conductors.
Claims33
A switch device comprising:
- a first conductor connected to an external circuit and having a relatively high ionization tendency;
- and
- a second conductor arranged close to the first conductor and having a relatively low ionization tendency which is lower than that of the first conductor, wherein a reaction part which electrically corrodes the first conductor is formed by a liquid between the first and second conductors.
An electronic component comprising:
- an external-connection terminal connected to an external circuit;
- and
- a conductor arranged close to the external-connection terminal and having a relatively low ionization tendency which is lower than that of the external-connection terminal,
- wherein a reaction part which electrically corrodes the external-connection terminal is formed by a liquid retained between the external-connection terminal and the conductor.
A battery cell comprising:
- a first conductor continuous with a positive electrode terminal connected to an external circuit;
- and
- a second conductor continuous with an external can which is a negative electrode and which is arranged close to the first conductor, the second conductor having a relatively low ionization tendency which is lower than that of the first conductor,
- wherein a reaction part which electrically corrodes the first conductor is formed by a liquid retained between the first conductor and the second conductor.
A battery system comprising:
- a battery;
- and
- a conductor arranged close to a terminal of the battery and having a relatively low ionization tendency which is lower than that of the terminal,
- wherein a reaction part which electrically corrodes the terminal is formed by a liquid retained between the terminal and the conductor.
