Description
Technical field
The utility model relates to usb data line design field, particularly a kind of quick charge formula usb data line.
Background technology
USB(Universal Serial Bus), Chinese is USB, and its Chinese is referred to as " logical get lines crossed ", is an external bus standard, for being connected and communication of specification computer and external equipment.It is the interfacing that is applied in PC field.The plug and play of USB interface support equipment and warm connection function.USB will combine proposition in the end of the year 1994 by Intel, Compaq, IBM, Microsoft Deng Duo company.
Usb data line is a kind of cable that meets above-mentioned interfacing.At present, usb data line has become the standard fitting of mobile phone, for the transfer of data between mobile phone and computer, and for charging.Existing usb data line structure is formed by connecting by data cable by a USB interface male seat and a USB interface female seat conventionally.Mobile phone is in using the charging of usb data line, and the mode that can select common are two kinds, and a kind of is the electronic equipment directly by usb data line connection computer etc. with USB interface, and another kind is to connect civil power by power supply adaptor.Existing usb data line is in the time connecting civil power by power supply adaptor, larger electric current can be provided, ensure mobile phone quick charge under the prerequisite of safe charging, but this usb data line is in connecting the electronic equipments such as computer, the electric current that electronic equipment provides even can be low to moderate 500 milliamperes, and charge efficiency is extremely low.
Summary of the invention
The utility model embodiment goal of the invention is to provide a kind of quick charge formula usb data line, and applying this technical scheme, can to realize by electronic equipments such as computers be mobile phone quick charge, and charge efficiency is higher.
In order to realize foregoing invention object, complete skill scheme of the present utility model is:
A kind of quick charge formula usb data line, comprises USB interface male seat, the first USB interface female seat, secondary USB interface female seat; Described USB interface male seat is connected with described the first USB interface female seat by cable; Described cable comprises power line, anodal data wire, negative pole data wire, ground wire; Described secondary USB interface female seat have power line pin, anodal data wire pin, negative pole data wire pin, wire pin; Described power line pin and described power line are electrically connected; Described ground wire pin and described ground wire are electrically connected; Described anodal data wire pin and described negative pole data wire pin are electrically connected.
Therefore application the present embodiment technical scheme, by increasing secondary USB interface female seat as quick charge interface, is electrically connected power line pin and described power line; Described ground wire pin and described ground wire are electrically connected; Described anodal data wire pin and described negative pole data wire pin are electrically connected, in connecting electronic equipment, can be identified as Charging Downstream Port, now also can provide large current charge by the USB interface of electronic equipment, improve charge efficiency.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation that Fig. 1 provides for the utility model embodiment 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
embodiment 1:
As shown in Figure 1, the present embodiment provides a kind of quick charge formula usb data line, comprises USB interface male seat 110, the first USB interface female seat 120, secondary USB interface female seat 130; USB interface male seat 110 is connected with the first USB interface female seat 120 by cable; This cable comprises power line 121, anodal data wire 123, negative pole data wire 124, ground wire 122; Secondary USB interface female seat 130 have power line pin 131, anodal data wire pin 133, negative pole data wire pin 134, wire pin 132; This power line pin 131 is electrically connected with power line 121; Ground wire pin 132 is electrically connected with ground wire 122; Anodal data wire pin 133 is electrically connected with described negative pole data wire pin 134.
The present embodiment is in the time using power supply adaptor to charge, USB interface male seat is inserted to power supply adaptor, the first USB interface female seat or secondary USB interface female seat are inserted to mobile phone, and mobile phone all can be identified as Charging Downstream Port, all can provide large electric current to charge.In the time using the USB interface of electronic equipment to charge, USB interface male seat is inserted to USB interface, secondary USB interface female seat is inserted to mobile phone, due to anodal data wire pin and the state of negative pole data wire pin in docking, mobile phone can be identified as Charging Downstream Port, now also can provide large current charge by USB interface, ensure charge efficiency.
The present embodiment ensures no matter user is in the time using power supply adaptor or the USB interface of electronic equipment, all can ensure to provide large current charge, and charge efficiency is higher.
Above-described execution mode, does not form the restriction to this technical scheme protection range.The amendment done within any spirit at above-mentioned execution mode and principle, be equal to and replace and improvement etc., within all should being included in the protection range of this technical scheme.
