Document Type and Number:
Japanese Patent JP6394535
Kind Code:
B2
Abstract:
An electric wire protection device comprising a pyrotechnic cutoff switch disposed between an electric wire connecting a load and a vehicle-mounted power supply that is connected to a reference potential. The pyrotechnic cutoff switch is disposed between the electric wire and has: a conductive part through which current between the vehicle-mounted power supply and the load flows; a cutting blade cuts the conductive part; a drive part, actuated by gunpowder, propels the cutting blade in a direction in which the conductive part is to be cut; and first and second terminals that input and output current that drives the drive part. In addition, the electric wire protection device comprises: a conductive wire having one end thereof connected to the electric wire and the other end thereof connected to the first terminal; and a diode having an anode connected to the reference potential and a cathode connected to the second terminal.
