Abstract

The invention provides a PC (Personal Computer) network interface circuit structure. The PC network interface circuit structure comprises an intel network cable input interface and an intel network cable output interface which are in communication connection with each other, wherein a thunder prevention network is connected between the input interface and the output interface. According to the PC network interface circuit structure, an I/O (Input/output) network interface thunder prevention circuit is additionally arranged in a PC power supply; a dialer network cable is inserted and input into a PC power supply network interface, and then the dialer network cable is output from the PC power supply network interface and connected to a computer network card, so that the thunder prevention of the network card is implemented.

Description

technical field [0001] The present application relates to the field of computer hardware, and in particular to a PC (Personal Computer, personal computer) network port circuit structure. Background technique [0002] A PC power supply is a device that provides power support in a PC computer. The traditional PC power supply is transformed into +12V / +5V / +3.3V / -12V / 5VSB five kinds of direct current through 220V AC, which meets the requirements of the CPU, graphics card, motherboard, hard disk, optical drive and radiator inside the host computer. For normal operation, conventional PC power supplies need to integrate overvoltage / overcurrent / overload protection, and the overvoltage protection is the lightning protection in normal use. While the PC power supply provides DC power for the computer host accessories, it also undertakes the task of preventing the host accessories from being scrapped due to lightning overvoltage for the corresponding electrical equipment. [0003] The ...
