Abstract

The utility model relates to the technology field of electronic adapters, in particular to a USB hub. The USB hub comprises a data line, a USB receptacle and a USB plug. The USB receptacle and the USB plug are respectively connected with two ends of the data line. The USB receptacle is fixed on a circuit board which is printed with a power circuit for powering the USB receptacle. The circuit board is assembled with a power socket for powering the power circuit. The utility model provides an individual power circuit for the USB receptacle. If the charging is required, an output plug of a charger is inserted into the power socket, and an electric appliance is inserted in the USB receptacle so as to fulfill the charging function, thereby the use is very convenient.

Description

Usb hub

Technical field:

The utility model relates to electronic transfer unit technical field, particularly usb hub.

Background technology:

Along with continuous progress in science and technology, electronic information technology obtains fast development.In computer data transmitting device field, USB interface becomes data transmission interface of new generation.For easy to use, people have developed the data-interface adapter, and promptly the two ends of data wire are connected with data-interface respectively, and configurable a plurality of interfaces of an end wherein are to realize the transfer of data of " one-to-many ".Most of electronic products all has stronger compatibility at present, for example products such as mobile phone, digital camera can be connected to the USB interface of host computer, utilizes the charging of the working power realization of computer to mobile phone and digital camera.Certainly, and though be existing computer USB interface also or the data-interface adapter, if give outside electrical equipment charging, it is in running order must to guarantee to provide the electrical equipment of power supply, the power supply that could be provided for charging for outside electrical equipment, thereby use inconvenience.

The utility model content:

The purpose of this utility model is to provide usb hub at the deficiencies in the prior art, and it has characteristics easy to use.

For achieving the above object, the utility model adopts following technical scheme:

It comprises data wire, and the two ends of data wire are connected with USB socket, USB plug respectively; USB socket is fixed on the wiring board, prints the power circuit of promising USB socket power supply on the wiring board, the supply socket of the promising power circuit power supply of assembling on the wiring board.

Be fixed with a plurality of USB socket on the described wiring board, each USB socket all is connected with power circuit.

The beneficial effects of the utility model are, for USB socket provides independent power circuit, use charge function if desired, then the output plug with charger inserts in the supply socket, the electrical equipment that will need then to charge is plugged in USB socket, just can realize charge function, communication function, very easy to use.

Description of drawings:

Fig. 1 is an internal structure schematic diagram of the present utility model

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

The following stated only is a better embodiment of the present utility model, does not therefore limit protection range of the present utility model.

See accompanying drawing 1, the utility model comprises data wire 1, and data wire 1 can be the general data line, also can be the folded data wire that has spooler, and the two ends of data wire 1 are connected with USB socket 2, USB plug 3 respectively; USB socket 2 is fixed on the wiring board 4, print the power circuit of promising USB socket 2 power supplies on the wiring board 4, the printing of this power circuit can design according to different product, the supply socket 5 of the promising power circuit power supply of assembling on the wiring board 4, power supply is provided by supply socket 5 by power circuit, and the model of supply socket 5 is also decided by different products.

Be fixed with a plurality of USB socket 2 on the described wiring board 4, each USB socket 2 all is connected with power circuit, is the schematic diagram of four USB socket 2 among Fig. 1, and is the internal structure schematic diagram of unassembled shell.

Generally speaking, the utility model adapter can be used as the common transfer device to be used, when needs use charge function, only need the output plug of charger is inserted in the supply socket 5, the electrical equipment that will need then to charge is plugged in USB socket 2, just can realize charge function, communication function, and the used electric current of USB socket 2 provides by supply socket 5 by the external charge device, very easy to use.

Be external in electrical equipment on the hub and can't influence the use of computer.The computer that connects with hub, if in running order, the electrical equipment that then is external in hub both can with compunlcation, also can charge; Computer is external in the electrical equipment of hub when off-mode, still can realize charging by external charger, and is very easy to use.
