Background

Piezoresistor "; the resistor device with the nonlinear volt-ampere characteristic is mainly used for voltage clamping when a circuit bears overvoltage and absorbing redundant current to protect sensitive devices. The english name "Voltage Dependent Resistor" is abbreviated as "VDR", or Varistor ". The resistor material of the varistor is a semiconductor, so it is a kind of semiconductor resistor. Currently in great use "; a zinc oxide (ZnO) piezoresistor is composed of main body material consisting of bivalent Zn and hexavalent O. From a material point of view, zinc oxide piezoresistors are therefore "ii-vi oxide semiconductors". In taiwan, the piezoresistors are called "; surge absorbers ", also sometimes referred to as" electric shock (surge) suppressors (absorbers) ".

The piezoresistor is a voltage limiting type protection device. By utilizing the nonlinear characteristic of the piezoresistor, when the overvoltage occurs between two poles of the piezoresistor, the piezoresistor can clamp the voltage to a relatively fixed voltage value, so that the protection of a subsequent circuit is realized. The main parameters of the piezoresistor are as follows: voltage-sensitive voltage, current capacity, junction capacitance, response time, etc.

However, when the existing plug is used, the two pins are installed when being installed in the socket, the two pins are not firm enough, when the two pins are inserted inwards, the positions of the pins are easy to move, the existing plug is not provided with a structure for radiating the piezoresistor, and the high temperature of the piezoresistor is easy to influence the use.
