CN202276025U - Universal serial bus (USB) power strip - Google Patents

Abstract

The utility model discloses a USB power supply socket. A plurality of USB sockets are installed on the socket box, and the wiring relationship of each USB socket is connected in parallel. There is a small transformer, and the output voltage of the small transformer is 5V, which no longer supplies power to the peripheral equipment of the computer through the computer USB interface, and protects the internal circuit of the computer.

Description

USB power strip

technical field

The utility model relates to a plug strip, in particular to a USB power supply plug strip.

Background technique

At present, there are more and more computer peripheral products that need USB power supply. The original intention of these peripheral products is to provide some convenience for computer users, but sometimes it is necessary to use several USB The number of USB interfaces has been difficult to meet the needs. At the same time, connecting many devices that need USB power supply to the USB interface of the computer increases the power consumed by the computer and accelerates the aging of the notebook computer.

Therefore, prior art awaits further improvement and development.

Utility model content

In order to solve the defects in the prior art, the utility model provides a USB power supply plug-in strip, which supplies power for computer peripheral products that need USB power supply.

In order to solve the above problems, the utility model scheme includes:

A USB power supply strip, with USB sockets installed on the strip box, and the wiring relationship of each USB socket is in parallel; the USB power supply strip is powered by an external 220V power supply through the plug, and a small transformer is installed in the plug box or at the plug. The output voltage is 5V, and no longer supplies power to computer peripheral devices through the computer USB interface.

Description of drawings

Fig. 1 is a schematic diagram of the utility model, in Fig. 1 , a plug 1, a connecting wire 2, a socket box 3, and a USB socket 4.

Detailed ways

The utility model provides a USB power supply socket. In order to make the purpose, technical solution and advantages of the utility model clearer and clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings.

When in use, insert the plug 1 into the domestic mains socket to obtain electric energy; the small transformer installed inside the plug or the plug box 3 converts the mains power to 5V voltage for use by the equipment; The internal circuit of the box is connected; the USB socket 4 is installed on the plug-in box 3, and the wiring relationship of each USB socket is parallel connection.

When in use, insert the plug into the household mains socket, the transformer converts the mains voltage to 5V, and sends the 5V voltage to each USB socket on the plug-in box through the line. For example, the external cooling fan of the computer with the USB interface needs to be powered by a power supply. You can just plug the USB plug into the USB socket of the plug-in box instead of plugging it into the USB port of the computer, which saves the use of the USB port of the computer and prevents the phenomenon that the current of a single USB port on the computer is too large. To a certain extent, the internal circuit of the computer is protected.

Claims (3)

1.USB the power supply insert row is characterized in that being equipped with on the insert row box a plurality of USB sockets, the USB insert row is through the external 220V power supply power supply of plug, and in the insert row box or plug place is equipped with miniature transformer.

2. USB power supply insert row according to claim 1, it is characterized in that: the voltage of miniature transformer output is 5V.

3. USB power supply insert row according to claim 1 is characterized in that: each USB socket circuit wiring relation is parallel connection on the insert row box.
