Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
Embodiment one
Fig. 1 is a kind of structural schematic diagram for general-purpose serial bus USB connecting line 1 that the embodiment of the present invention one provides, including
Positive wire 1-1 and cathode conductor 1-2, the first end of the positive wire 1-1 are connected with the first end of the cathode conductor 1-2
To USB interface, the USB interface is for connecting 2 with equipment under test, the data anode 1-3 and data minus of the USB connecting line 1
Pole 1-4 is shorted, and the second end of the positive wire 1-1 is used for and is being capable of the charger analog machine 3 of output services parameter just
The connection of pole output port, the second end of the cathode conductor 1-2 is for the cathode output end mouth with the charger analog machine 3
Connection.
Wherein, equipment under test can be mobile phone (smart phone or non-smart mobile phone), tablet computer, laptop, intelligence
Energy wearable device etc. carries the electronic equipment of battery.
The charger analog machine 3 for capableing of output services parameter, which can be, can export constant current (or voltage) and show
The power-supply device of the current value (or voltage) of output.Programmable power supply can be selected to simulate as charger in one implementation
Equipment 3.Programmable power supply can produce the high-power power-frequency voltage that amplitude, frequency, phase angle are adjustable, stable, current signal.It is main to use
In the test and calibrating of electric current, voltage, phase, frequency, power meter；Can also matching standard power ammeter, to electric energy meter (electric degree
Table) elementary error, shunt running, sensitivity verified and examined and determine.Illustratively, can be used three-phase program-controlled precision measurement power supply,
Single-phase programme control precision tests power supply or DC current regulator power supply etc..Preferably, using Agilent66319D programmable power supply.
It since electronic equipment is when being charged, charges usually using direct current, therefore controllable programmable power supply exports constant electricity
Stream.
Currently, electronic equipment (such as mobile phone or tablet computer) can be connect by USB connecting line 1 with transformer, pass through transformation
The connection of the power supply of device and 220V.The embodiment of the present invention is by being transformed the existing USB connecting line 1 used of electronic equipment, energy
Access a kind of USB connecting line 1 suitable for battery testing.When transformation by the data anode 1-3 (data+) of USB data line and
Data cathode 1-4 (data-) is shorted, so that USB data line saves USB connecting line 1 while retaining original Interface Shape
Data-transformation facility retains electric energy transfer function.
Optionally, when being shorted data anode 1-3 and data cathode 1-4, first using tools such as scissors, pliers, by USB
Data line is splitted, and then uses soldering appliance or conductive wire connection tool by the data anode 1-3 and data cathode in USB data line
1-4 is shorted.Optionally, the pin of the pin of the data anode 1-3 on USB interface and data cathode 1-4 is shorted, with reality
The short circuit of existing data anode 1-3 and data cathode 1-4.
With the brand of electronic equipment (such as mobile phone or tablet computer) and the difference of model, the joint geometry of USB connecting line 1
Also it is not quite similar.Identical to be, USB interface is by positive pole, power cathode, data anode 1-3 (data+) and data cathode
1-4 (data-) composition.Therefore, it is based on above-mentioned improved procedure, it can be by the data anode 1- of the USB connecting line 1 of any electronic equipment

Fig. 2 is a kind of structural schematic diagram of USB connecting line 1 provided by Embodiment 2 of the present invention, as to embodiment one
It further illustrates.For electronic equipment when determining the type of USB interface insertion cable, the decision procedure of different device manufacturers is
It is different；And impurity such as is generated in process of production, lead to the electricity between the data anode 1-3 of USB interface and data cathode 1-4
The problem of potential difference not necessarily 0, there may be erroneous judgements in such a way that embodiment one provides at this time.Based on this, the USB is connect
Preset resistance 5 is in series between the data anode 1-3 and data cathode 1-4 of mouth.
Wherein, the resistance value of preset resistance 5 is greater than 0, and optionally, the resistance value of preset resistance 5 is 0.5-2 ohm, preferably 1 Europe
Nurse.It is poor that preset resistance 5 is used to provide stable predeterminated voltage for data anode 1-3 and data cathode 1-4.Electronic equipment judgement
Whether the data anode 1-3 and your voltage difference of the family of data cathode 1-4 of USB interface are that the predeterminated voltage is poor.If voltage difference
It is poor for the predeterminated voltage, then it can determine that the cable of insertion is power supply line；If voltage difference is not that the predeterminated voltage is poor, can determine
The cable of insertion is data line.
