Abstract
To provide an electric circuit breaker device that can be downsized while maintaining strength. An igniter 20, a bar-shaped projectile 40, a conductor piece 50, and an insulating space 61 are provided inside a resin housing 10. A cylinder 30 is disposed between the bar-shaped projectile 40 and an inner wall surface of the housing 10, and a reinforcing frame 70 is disposed in the housing 10 on the outer side.
Claims19
An electric circuit breaker device, comprising:
- a housing made of a synthetic resin;
- an igniter;
- a bar-shaped projectile made of a synthetic resin;
- a conductor piece forming a part of an electric circuit, the igniter, the bar-shaped projectile, and the conductor piece being disposed in this order from a first end side of the housing to an axially opposite second end side of the housing;
- and
- a cylinder made of metal disposed between the bar-shaped projectile and an inner wall surface of the housing, wherein
- a closed insulating space is formed between the second end of the housing and the conductor piece,
- the conductor piece is a plate piece comprising a first connection portion and a second connection portion at opposite ends and an intermediate cutting portion, with a surface of the cutting portion being disposed orthogonal to an axial direction of the housing,
- the bar-shaped projectile opposes the surface of the cutting portion of the conductor piece in the axial direction of the housing, and
- a reinforcing frame, reinforcing the housing, is provided separately from the conductor piece and disposed within the housing outside of the cylinder and the insulating space, the reinforcing frame being a metallic member.
