Problems solved by technology

[0004] 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 a dangerous voltage, the user of the electronic device cannot directly identify and judge that the electronic device has a dangerous voltage, which seriously affects the safety of use and life.

Abstract

An electric leakage alarm power supply adapter is provided. Safety of charging or power supply to a human body can be increased. The electric leakage alarm power supply adapter comprises an adapter main body and an output port. The adapter main body is used for acquiring an alternating current from a power supply and converting the alternating current into a direct current possessing an assigned voltage. The output port contains an anode output port and a cathode output port which are electrically connected to the adapter main body, and is used for acquiring the direct current from the adapter main body and providing the direct current to external equipment through the anode output port and the cathode output port. An electric leakage detection alarm module is connected and configured between the anode output port and the cathode output port. In the invention, when an electric leakage danger signal leaked abnormally from the output port is detected, an alarm device emits a warning so as to prompt a user that electric leakage is generated on equipment and the equipment is dangerous.

Description

technical field [0001] The invention relates to the technical field of charging and electric leakage detection, and more particularly, relates to a power adapter with electric leakage alarm. Background technique [0002] At present, mobile terminal electronic devices such as mobile phones are usually equipped with a rechargeable battery, so the battery needs to be charged through a power adapter. [0003] When charging or supplying power, the power adapter converts AC power into DC power of a specified voltage and transmits it to electronic equipment. [0004] 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 ...
