AI Technical Summary

Problems solved by technology

The electric spark phenomenon may cause the plastic material around the conductive contact to burn and blacken, resulting in a burnt smell, and even the conductive contact may cause poor contact due to carbon deposits
Therefore, the spark phenomenon not only causes poor user experience for consumers, but may also affect the functions of electronic devices

Abstract

The invention discloses a power connection management device which is arranged between a system load of an electronic device and a power connection point. The power connection management device comprises an input capacitor and a switching circuit, wherein one end of the input capacitor is electrically connected with a power output end of the power connection point and a power input end of the system load, and the other end of the input capacitor is electrically connected with a system grounding end of the system load; the switching circuit is electrically connected with the system grounding end of the system load and a power grounding end of the power connection point; and when external power is connected to the power connection point, the switching circuit is switched on.

Description

technical field [0001] The present invention relates to a power connection management device, in particular to a power connection management device which prevents electric sparks from being generated when an electronic device is connected to an external power supply. Background technique [0002] Most of the electronic devices need to be connected to an external power supply to provide the power required for the operation of the electronic devices. For example, the electronic device can be directly plugged into a socket supplying commercial power with a power plug, or the electronic device can be connected to a power adapter (power adapter) with a power adapter socket, and the power adapter can be plugged in again. to an outlet to provide the required power. [0003] Generally speaking, most electronic devices provide an input capacitor between the system load and the power supply end. When the electronic device is connected to the power supply, it is unavoidable that spar...
