Description
[technical field]
The utility model relates to a kind of Cellphone Accessories, relates in particular to a kind of charger for mobile phone of integrated data transfer function.
[background technology]
Mobile phone products is used universal day by day, and cell-phone function from strength to strength.Present cell-phone function has been not limited to and has made a phone call, overwhelming majority mobile phone has picture, the tinkle of bells, multimedia message, music, film, recreation transmission (download and shift) function, download (being designated hereinafter simply as the transfer of data mobile phone) such as mobile phones as MP3 mobile phone, MP4 mobile phone, multimedia message, important and universal a kind of data wire that is to use carries out transfer of data in the method for mobile phone transmission data.In the standard fitting of existing transfer of data mobile phone, usually a data wire and a charger be equipped with, data wire and charger are independently finished the function of transfer of data and charging respectively, must carry data wire and charger when trip, make troubles to the user.
As shown in Figure 1, be connection diagram when utilizing charger that mobile phone is charged in the prior art.Power supply is connected on the mobile phone by charger attaching plug, bus, Mobile phone plug successively, thereby has realized the charge function to mobile phone.The circuit connection diagram that charger is inner concrete, referring to Fig. 2, wherein, V+ is the positive pole of direct current, Gnd is a ground wire, two independently leads are arranged in the bus, and between the positive pole of positive pole that is connected the charger attaching plug and Mobile phone plug, another root then is connected between the ground wire of the ground wire of charger attaching plug and Mobile phone plug.
As shown in Figure 3, be to utilize data line mobile phone to be carried out the connection diagram of transfer of data in the prior art.Digital processor is connected on the mobile phone by the data wire plug on data wire USB plug, bus, the mobile phone successively, thereby has realized mobile phone is carried out the function of transfer of data.The circuit connection diagram that data line is inner concrete is referring to Fig. 4, wherein, D+ is the correction data line, and D-is the negative data line, and four independently leads are arranged in the bus, correction data line and negative data line are used for transmission of data signals, and the positive pole of direct current and ground wire then are used to provide the function of power supply.
In addition, because the charger interface of mobile phone and the data line interface of mobile phone can be designed to shared standardization device (and generally being designed to shared interface now), if data wire and charger still are separate, will increase the cost of Cellphone Accessories, cause the waste of resource.
[summary of the invention]
The technical problems to be solved in the utility model provides a kind of charger for mobile phone of integrated data transfer function, makes charger for mobile phone not only have charge function, but also has data-transformation facility, has reduced the cost of Cellphone Accessories, has saved resource.
The utility model is to realize by following technical scheme:
A kind of charger for mobile phone of integrated data transfer function, comprise the charger attaching plug and the shared Mobile phone plug that are electrically connected mutually by a pair of power line, also comprise a data wire USB plug, described data wire USB plug is electrically connected with shared Mobile phone plug by a pair of data signal line.
Improvement of the present utility model is: described data wire USB plug also is electrically connected with shared Mobile phone plug by described a pair of power line.
Because adopted above technical scheme, the utility model possesses charge function and data-transformation facility simultaneously, does not need extra data line, has reduced the cost of Cellphone Accessories; The utility model both can be used for connecting mobile phone and power supply, carried out cell-phone charging, also can be used for connecting mobile phone and digital processor, carried out transfer of data; Simultaneously, when trip, brought convenience also for the user.

[embodiment]
Below in conjunction with drawings and Examples the utility model is further set forth:
As shown in Figure 5, be the connection diagram of utilizing the utility model simultaneously mobile phone to be charged and carrying out transfer of data.Power supply is connected on the mobile phone by charger attaching plug, bus, shared Mobile phone plug successively, realizes the charge function to mobile phone; Digital processor is connected on the mobile phone by data wire USB plug, bus, shared Mobile phone plug successively, realizes the data-transformation facility to mobile phone.Charger attaching plug and data wire USB plug all are arranged on the charger, and charging and transfer of data can be carried out simultaneously, and be easy to use.
As shown in Figure 6, be the circuit connection diagram of the utility model inside.Charger attaching plug and data wire USB plug all are electrically connected with shared Mobile phone plug by bus, wherein, four separate leads are arranged in the bus, are respectively: direct-flow positive pole line V+, ground wire Gnd, correction data line D+, negative data line D-.Direct-flow positive pole line and ground wire form a pair of power line, are used for the transmission of power supply signal, and correction data line and negative data line form a pair of data signal line, are used for the transmission of data-signal.Be electrically connected by direct-flow positive pole line V+, ground wire Gnd between charger attaching plug and the shared Mobile phone plug, then be electrically connected between data wire USB plug and the shared Mobile phone plug by direct-flow positive pole line V+, ground wire Gnd, correction data line D+, negative data line D-.
When using the utility model that mobile phone is charged, electric current flows among the mobile phone by charger attaching plug, direct-flow positive pole line V+ and ground wire Gnd, shared Mobile phone plug; When using the utility model that mobile phone is carried out transfer of data, the data-signal that flows out from digital processor flows among the mobile phone by data wire USB plug, correction data line D+ and negative data line D-, shared Mobile phone plug.Two kinds of functions are not disturbed mutually, and the utility model combines charger for mobile phone and data wire, are user-friendly to, and have saved the cost (2 yuan of about RMB) of a Mobile phone plug and a DC leadout.
