Description

USB multi-function charging interface

technical field

The utility model relates to a USB charging device, in particular to a USB multifunctional charging interface device. the

Background technique

In the prior art, USB charging devices have been widely used, but the current USB charging devices generally rely on a computer or household power supply, and use a charging cable with a USB interface to realize the charging function. Especially when using civilian electricity to charge, a power adapter needs to be used separately so that the power socket can be converted into a USB interface for use, which is not only inconvenient to use, but also the power adapter is easy to damage. the

Contents of the invention

Aiming at the above problems, the utility model provides a USB multifunctional charging interface device, which can be directly installed on the wall and directly used as a USB charging interface. the

The technical scheme that the utility model solves its technical problem adopts is:

A USB multifunctional charging interface device, comprising a female base, a charger module is arranged in the female base, one side of the charger module is connected to a USB socket provided in front of the female base, and the other side is connected to a zero line arranged behind the female base Firewire connection point. the

A safety door is provided on the USB socket. the

A power-on indicator light is arranged in the USB socket, and the power-on indicator light is connected to the charger module. the

A USB multifunctional charging interface device of the present utility model, which can be directly installed on the wall by configuring the socket body, and its interior is directly connected to the mains power supply, and its external shape is similar to the current network cable interface or telephone line interface, but It can be used directly as a USB charging interface, and can be used with a USB data cable to charge external devices. the

The utility model is connected to the power supply only when the safety door is opened (the power-on indicator light is on). When the safety door is closed, the USB socket is not charged (the power-on indicator light is turned off). Connect the power supply, prolong the life of the equipment, save power, eliminate potential safety hazards, and can be flexibly assembled with the panel. the

Compared with the prior art, a USB multifunctional charging interface of the present invention has the characteristics of reasonable design, simple structure, convenient use, safety and power saving, and long service life. the
