Airbags are a device that protects occupants from the impact when a car crashes. This air bag will be briefly explained. An ignition device is attached to a loading chamber loaded with a gas generating agent that generates gas for inflating the air bag, and a signal line is attached to the ignition device. A battery as a power source and a collision sensor as a switch are connected to this signal line to form an air bag circuit. This circuit is divided into a power supply side and a device side by a connector interposed between the signal lines. When a car collides, a collision sensor detects the collision and sends an electrical signal to the ignition device, which ignites the gas generating agent and generates a large amount of gas, inflating the air bag and protecting the occupants from the impact of the collision. This air bag must operate at the moment of a collision, but conversely, it must be absolutely avoided that it operates at any time other than at the time of a collision.

ている。 When installing and inspecting this air bag, the connector that connects the signal line on the power supply side and the signal line on the load device side is disconnected, but at that time the terminal provided inside the connector halogen is left open. Become. In such a case, there may be another wire near the signal line on the equipment side, and a current may flow into it, or something charged with static electricity may come into contact with it, or the terminal on the equipment side may be exposed to electromagnetic waves from the outside. When the magnetic field or electric field is induced by this, a voltage is applied to the signal line primarily, and a voltage is generated between the signal lines depending on the strength or weakness of the influence of the magnetic field or electric field that each signal line receives, and the load Current flows primarily through the device. Even if the current that flows due to this is minute, the air bag is driven even by a minute current, which causes malfunction.

で、11は電源側の信号線である。 FIG. 2 shows a state in which the male and female connector housings are fitted, and FIG. 3 shows a state in which they are not fitted. The male terminal 9 is inserted into the female terminal 1 through a fitting hole 8 formed in the male connector housing A, and is pressed into contact with the leaf spring 2. The male terminal 9 is a square cylindrical contact portion 1a between the leaf spring 2 and the female terminal 1.
When the leaf spring 2 is clamped and fitted, the male terminal 9 pushes the leaf spring 2 downward in the figure, and the rear end 2' of the leaf spring and the shorting plate 3 are separated and the contact is broken. It's summery. 10 is a signal line on the device side, and 11 is a signal line on the power supply side.
