Abstract
To provide an electric circuit breaker device including a conduction part that can be easily cut. An electric circuit breaker device includes a housing made of synthetic resin, a rod-like projectile made of synthetic resin and arranged in the housing, a conductor portion arranged in the housing to extend across a front face of one end portion of the rod-like projectile, and an igniter arranged in the housing to face another end portion of the rod-like projectile and configured to generate pressure to fire the rod-like projectile toward the conductor portion. In one embodiment, the conductor portion includes a first conductor plate extending across the front face of the one end portion of the rod-like projectile and including a recess portion, and a second conductor plate coupled to the recess portion of the first conductor plate. In another example, the conductor portion includes a first conductor plate arranged on the front face of one end portion of the rod-like projectile, and a second conductor plate and a third conductor plate coupled, at a corresponding one of edge portions of the second conductor plate and the third conductor plate, to respective opposing edge portions of the first conductor plate.
