Abstract

The invention relates to a sensor for using impact to break circuit, wherein it comprises impact strength sensor, signal transmission amplifier, and executer; said sensor is connected to the amplifier connected to executer; said sensor can cut circuit instantly when the vehicle is impacted, to avoid electric splash.

Description

technical field [0001] The invention relates to an inductive device, in particular to an inductive device for disconnecting a circuit by using deformation caused by a vehicle being hit. Background technique [0002] When the vehicle is impacted by an external force, especially when the impact force is relatively large, the fuel tank or oil pipeline will often be ruptured to cause fuel leakage. The short circuit of the vehicle's electrical circuit caused by the impact will generate electric sparks, which can easily cause the fuel to catch fire or even explode, leading to more serious secondary disasters. The traditional device or method to prevent electrical circuit short circuit is to connect an overcurrent protector in series in the circuit. When the short circuit occurs, it will heat up and fuse or temporarily cut off the circuit due to the increase of current. However, considering that the overcurrent protector is too sensitive to current changes, a certain design margin...
