Abstract

The invention provides a USB connection socket capable of electric leakage warning. The USB connection socket is connected between a data line of a mobile terminal such as a mobile phone and a power adaptor and is used for charging the mobile terminal such as the mobile phone and detecting an electric leakage condition of the power adaptor so as to improve the safety of charging on a human body. The USB connection socket capable of electric leakage warning comprises a USB male head interface, a USB female head interface, a PCB and a shell, wherein the PCB also comprises an electric leakage detection and warning module, and the electric leakage detection and warning module comprises a warning device and is electrically connected and configured between a connection electrode Vbus and a connection electrode GND. With the adoption of the USB connection socket, the warning device gives out a warning to remind a user of live-line risk of equipment when that an electric leakage risk signal isabnormally leaked onto the USB connection socket capable of electric leakage warning from the external power adaptor is detected.

Description

technical field [0001] The invention relates to the technical field of a USB connection socket and leakage detection, in particular to a leakage warning USB connection socket with a leakage warning function during charging. Background technique [0002] At present, mobile terminals such as mobile phones and other small digital electronic devices are usually equipped with rechargeable batteries, so it is necessary to connect mobile terminal electronic devices such as mobile phones to a power adapter through a USB data cable for charging. [0003] However, during the process of the power adapter converting the AC power into a DC power of a specified voltage and transmitting it to the electronic equipment, due to possible production process defects or component aging and improper use, the mains power on the AC side leaks to the DC terminal of the specified voltage, resulting in output When the terminal carries dangerous voltage, the user of electronic equipment cannot directly ...
