PURPOSE: Power supply cut off system for vehicle is provided to cut off power connects by pulling back wire body of main cable by gas pressure, generated from inflator, when a vehicle collision accident is occurred. CONSTITUTION: Using detonation pressure, inflator(40) pulls back wire body(20). Control unit senses impulse quantity by crash accident or current amount of system. If the impulse quantity or the current amount is greater than reference value, the control unit transmits detonation signal to the inflator. Connector(60) shuts rearward tightly to avoid detonation gas leaking. The connector supplies the detonation signal to the inflator.
