Circuit for preventing surge, connector and electronic apparatus thereof

摘要

A surge protection circuit and a connector and an electronic apparatus using the circuit are provided. The connector includes a plurality of metal lines (301-308), a plurality of resistors (311-314), a ground metal (201), and a capacitor (300). Each metal line has a pointed end. There is a distance between the pointed end of the metal lines and a pointed end of the first end of each resistor corresponding to the metal line. The capacitor is coupled between the ground metal and second end of the resistors. Thus the surge endurance of product can be increased by the invention, and the damage to the internal components of product can be prevented.
