Abstract

The invention discloses a safety power adapter, comprising a casing, a main circuit board, a sensor module, a secondary circuit board and a battery. The casing is provided with at least two pins suitable for being inserted into a jack of a power socket; the main circuit The board is arranged in the casing to convert alternating current into direct current suitable for supplying power to electrical equipment; the sensor module is arranged in the casing and is adjacent to the side where the pins are located, and the sensor module at least includes a capacitive sensor to detect the proximity of human fingers Capacitance signal at the pin; the auxiliary circuit board is arranged in the casing and has a processor and a buzzer. The processor is connected to the capacitive sensor to output the first control signal according to the detection signal of the sensor module, and the buzzer is connected to the processor. connected to output an alarm prompt according to the first control signal; the battery is arranged in the casing and connected to the auxiliary circuit board. The safety power adapter of the present invention can play the role of warning of electric shock danger, reduce the risk of electric shock, and improve the safety of the power adapter.

Description

technical field [0001] The invention relates to a power adapter, in particular to a safety power adapter. Background technique [0002] Power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is to convert AC input to DC The output can be divided into wall type and desktop type according to the connection method. [0003] In the related art, for a wall-plug power adapter, when the pins on the power adapter are inserted into the jacks of the power socket, there is a risk of electric shock, which may cause an electric shock accident due to fingers touching the pins. SUMMARY OF THE INVENTION [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the purpose of the present invention is to provide a...
