Resistance connecting device

摘要

A resistance connecting device includes a case inside of which a chamber is formed. The chamber includes inside an activating unit, a gas generating unit, a first connecting portion, and a second connecting portion. The first connecting portion and the second connecting portion extend from the inside to the outside of the case in a mutually separated state and are exposed in the chamber. The activating unit is held at a first position that does not cause contact with either of the connecting portions when the gas generating unit has not been activated and moves up to a second position to cause contact with both of the connecting portions as a result of activation of the gas generating unit. The activating unit, at the second position, functions as a resistor having a predetermined electrical resistance, and connects the connecting portions to one another.

1. A resistance connecting device comprising:
a case inside of which a chamber is formed; a movable member that is movable in the chamber; a gas generating unit provided on a back side of the movable member within the chamber and, as a result of an external signal, wherein the gas generating unit is activated to generate gas; and a pair of external connecting portions extending from an inside to an outside of the case in a mutually separated state, located at different positions in the chamber, and respectively exposed at a front side of the chamber, wherein the movable member is made of a resin material admixed with a conductivity-imparting agent in an amount providing the movable member with a predetermined electrical resistance corresponding to a resistor, the movable member is held at a first position in which the movable member is out of contact with at least one of the pair of external connecting portions when the gas generating unit has not been activated and moves to a second position to cause contact with both of the external connecting portions as a result of activation of the gas generating unit, and the movable member, at the second position, functions as a resistor having a predetermined electrical resistance and connects the external connecting portions to one another.
