Description

Power socket with USB interface

technical field

The utility model relates to a socket for providing power, in particular to a power socket with a USB interface. the

Background technique

At present, many mobile digital products are used in modern people's life, such as mobile phones, notebooks, digital cameras, MP3, MP4, IPad, etc. Since USB is an international standard for the communication interface between computers and digital products, it supports data exchange and hot swapping. And provide an output of 3V-36V DC voltage. Therefore, digital products basically use USB as an interface for data output and input and battery charging, and connect to a computer or a power adapter with a USB cable. the

The current standard voltage for Chinese residents is AC 220V, and there are no power sockets for daily use, including embedded wall power sockets, mobile power sockets, cabinet power sockets, desktop power sockets, functional power sockets, power pack power sockets, etc. The voltage used for digital products is equipped with a dedicated power adapter, which provides power and battery charging for digital products alone. Therefore, each digital product is equipped with a power adapter, resulting in a serious waste of resources. Especially when the power adapter is not carried or the power adapter is damaged when going out, after the battery is discharged, the digital product will stop using, which seriously affects the daily work and life. the

Utility model content

The purpose of this utility model is to provide a power socket with a USB interface, so that the cover of the power socket has a plug interface of the national standard voltage for residents, and also has a USB interface type socket with an output DC voltage of 3V-36V. the

The utility model is achieved in the following way: a power socket with a USB interface, including a bottom box and a cover, the cover has a standard two-pin plug insertion hole, or a three-pin plug insertion hole, its special The feature is: the face cover is provided with a USB interface; the USB interface is connected to the switching power supply module; the switching power supply module is connected to the AC220V input, and enters the transformer, rectification and filtering circuit through the rectification circuit, and outputs DC voltage 3V-36V is connected with USB interface;

The switching power supply module is arranged in the bottom box.

The utility model is a power socket with a USB interface. Due to the adoption of such a structure, there is a USB interface with a DC voltage of 3V-36V on the mobile power socket or the embedded wall power socket, which solves the problem of digital product power supply and battery charging relying on a special power supply. In the case of adaptation, there is an available power supply anytime, anywhere, and it is directly connected with a USB cable, which is convenient and flexible. the
