Description

A socket with a USB interface

technical field

The utility model relates to the technical field of power sockets, in particular to a socket with a USB interface.

Background technique

At present, the power sockets used on the market are generally provided with several two-hole or three-hole socket holes, and these socket holes all output 220V alternating current for plugging in computers, monitors, speakers, printers, copiers and other equipment. Yet this power supply socket still continues to use traditional technology, has only been provided with AC mains socket hole. And in recent years, various electronic products such as mobile phone, MP3, MP4, digital camera, DV etc. have been rapidly developed and widely used. These electronic products are generally provided with USB interfaces for data transmission and charging. At present, there are usually two ways to charge these electronic products, one is to use a specially configured power adapter, and the other is to use a USB port on a computer to charge. Due to the convenience of the USB interface, if the USB interface can be set on a traditional power socket, it will make the use of electronic products more convenient.

Utility model content
