The USB interface power strip employs the plurality of USB output interfaces, meets the charging requirements of a plurality of electronic products, has strong versatility and is convenient to carry; the USB interface power strip can meanwhile perform charging for the plurality of electronic products, and can detect the current required by charging equipment and provide corresponding current to the charging equipment.

Description

The USB interface power distributor
Technical field
The utility model relates to the power distributor technical field, is specifically related to a kind of USB interface power distributor.
Background technology
In the last few years, various electronic products such as mobile phone, MP3, digital camera, PDA etc. had obtained developing rapidly and extensive use, and these electronic products generally all are provided with USB interface, were used to transmit data or charging etc.These electronic products all are the power supply adaptor through special use usually or use that USB interface charges on the PC.But along with popularizing of these electronic products, everyone occupancy volume is also increasing sharply; If also only depend on existing power source special adapter that it is charged; Versatility is not strong, goes out all will carry a plurality of power supply adaptors at every turn, uses extremely inconvenience; The limitation of the USB port that PC charging can carry owing to PC again and can not guarantee to make each electronic product to be recharged simultaneously; Different in addition charging devices is not quite similar to the requirement of charging current, if the electric current of charging inlet can not adapt to the electric current of charging device needs, possibly will damage charging device.
The utility model content
To the deficiency of prior art, the purpose of the utility model aims to provide a kind of USB interface power distributor, solves the problems that the adaptive power supply versatility of current USB is strong and can not charge for a plurality of electronic products with USB interface simultaneously.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of USB interface power distributor comprises power adapter circuit, also comprises a plurality of USB output interfaces that electrically connect with said power adapter circuit.
Preferably, said power adapter circuit comprises transformer, rectification circuit, and said transformer one end links to each other with an AC power, and the other end is electrically connected to current detection circuit through rectification circuit.
As further improvement, also comprise a plurality of current detection circuits that are electrically connected between said USB output interface and the power adapter circuit.
Preferably, said current detection circuit is identical and corresponding one by one with the quantity of USB output interface.
A kind of USB interface power distributor that the utility model is set forth; Compared with prior art; Its beneficial effect is: adopt a plurality of USB output interfaces, can satisfy the charging problem of multiple electronic product, highly versatile and easy to carry; Can charge for a plurality of electronic products simultaneously again, but also can detect the required electric current of charging device and provide corresponding electric current to charging device.
Description of drawings
Accompanying drawing 1 is the structured flowchart of a kind of USB interface power distributor of the utility model preferred embodiment.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, a kind of USB interface power distributor of the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
Accompanying drawing 1 is the structured flowchart of a kind of USB interface power distributor of the utility model preferred embodiment.As shown in Figure 1, a kind of USB interface power distributor comprises power adapter circuit 2, a plurality of USB output interface 1, a plurality of current detection circuit 4.AC power 3 links to each other with usb 1 through power adapter circuit 2, current detection circuit 4; For providing voltage, USB output interface 1 supplies the charging device charging; Current detection circuit 4 is connected between power adapter circuit 2 and the USB output interface 1, and the quantity of current detection circuit 4 is identical and corresponding one by one with USB output interface 1.Power adapter circuit 2 is power supply adaptor circuit commonly used; Simplicity of design, cost are low; Comprise transformer and rectification circuit, the alternating current of AC power 3 is provided to USB output interface 1 by a plurality of suitable voltages of electronic product that meet of rectification circuit output after the transformer step-down, can charge for a plurality of electronic products simultaneously; Highly versatile, easy to carry.Current detection circuit 4 is used to detect the required electric current of charging device to be controlled the output current of USB output interface 1, promptly is that charging device needs great electric currents, the electric current of then corresponding with it USB output interface 1 output.Each USB output interface 1 all can be supported the quick-charge function of big capacity charging device such as mobile phone or panel computer in addition.
For a person skilled in the art,, make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to the technical scheme and the design of above description.
