For example, detection 200 USB cable are set.Or detect 200 USB cable and each USB cable detects 2 times.
After the number of times setting detection, the time starting to detect is set further, therefore after arriving the time arranged, one by one USB cable is powered successively, carry out characteristic test.
Step S2: detect electric current corresponding to each USB cable and whether meet default standard value.If the result detected is no, then jump to step S3, if when the result checked is, then jump to step S4.
In this step, concrete detection comprises at least one of following two kinds of situations:
The first, standard value comprises size criteria value, is preferably 500mA, 800mA and 1000mA.
This step is specially the size detecting electric current corresponding to each USB cable and whether meets default size criteria value.Specifically, if the size of electric current is higher than 1000mA, then the phenomenon of the damage equipment because electric current is excessive can be caused; If the size of electric current is lower than 500mA, then can cause charging slowly.
The second, standard value comprises floating standard value.This floating standard value ordinary representation electric current scope of fluctuating is no more than 10%.That is the scope that the electric current of USB cable departs from size criteria value is no more than 10%.
This step is specially the domain of walker of electric current in Preset Time detecting each USB cable corresponding and whether meets default floating standard value.Wherein, Preset Time is preferably set to the duration of charging, within being generally 2 hours.
Step S3: make prompting.
This step be specially prompting product defective and/or prompting user whether continue use charging.Preferably, accept the example above described in step S2, when the electric current of USB cable is higher than 1000mA, prompting product is defective.When the electric current of USB cable is lower than 500mA, whether prompting user continues to use charging.When the domain of walker of the electric current of USB cable is more than 10%, whether prompting product is defective or point out user to continue to use charging, or prompting product is defective and whether prompting user continues use charging
Step S4: do not point out.
In this step, do not point out the problem being specially and not pointing out user about USB cable.In addition, can also to show USB cable to user further qualified for this step.
Step S5: according to the problem of the outcome record USB cable detected, and the problem of record is analyzed.
This step is specially the problem that electric current is excessive or current floating is excessive occurred according to the outcome record USB cable detected, and goes out the qualification rate of USB cable in same production batch according to the interpretation of result of record.Wherein qualification rate is the ratio of qualified quantity/cable sum in same production batch.This step can also record the time detected further.The data of this concrete step record are preferably preserved with the form of excel form.
Described in brought forward, the present embodiment can realize the automatic test of USB cable performance, can require again to do over again after the qualification rate analyzing USB cable is not up to standard.To reduce the damage of USB cable charging equipment and terminal device.In addition, the present embodiment repeatedly can also be tested each USB cable, to reduce test error.

Wherein, supply module 101 is for powering to each USB cable successively.Wherein, the number of times needing to detect also was pre-set before power supply, wherein, the number of times of this detection can comprise detect USB cable number or the number of times that detects of each USB cable, or comprise detect USB cable number and the number of times that detects of each USB cable.
For example, detection 200 USB cable are set.Or detect 200 USB cable and each USB cable detects 2 times.
After the number of times setting detection, arrange the time starting to detect further, therefore after arriving the time arranged, supply module 101 is powered to USB cable successively one by one, carries out characteristic test.
Whether detection module 102 meets default standard value for detecting electric current corresponding to each USB cable.Concrete detection comprises at least one of following two kinds of situations:
The first, standard value comprises size criteria value, is preferably 500mA, 800mA and 1000mA.
Detection module 102 comprises size detection unit 121, and whether the size for detecting electric current corresponding to each USB cable meets default size criteria value.Specifically, if the size of electric current is higher than 1000mA, then the phenomenon of the damage equipment because electric current is excessive can be caused; If the size of electric current is lower than 500mA, then can cause charging slowly.
The second, standard value comprises floating standard value.This floating standard value ordinary representation electric current scope of fluctuating is no more than 10%.That is the scope that the electric current of USB cable departs from size criteria value is no more than 10%.
Detection module 102 comprises floating detecting unit 122 further, whether meets default floating standard value for detecting the domain of walker of electric current corresponding to each USB cable in Preset Time.Wherein, Preset Time is preferably set to the duration of charging, within being generally 2 hours.
Prompting is made when reminding module 103 is no for the result detected at detection module 102.Be specially prompting product defective and/or prompting user whether continue use charging.Preferably, accept previously described example, when the electric current of USB cable is higher than 1000mA, reminding module 103 points out product defective.When the electric current of USB cable is lower than 500mA, whether reminding module 103 points out user to continue to use charging.When the domain of walker of the electric current of USB cable is more than 10%, reminding module 103 point out product defective or prompting user whether continue use charging, or prompting product defective and prompting user whether continue use charging.
In addition, when the result that detection module 102 detects is for being, reminding module 103 is not pointed out, and is specially the problem not pointing out user about USB cable.But it is qualified that reminding module 103 can show USB cable to user further.
History Parser Module 104 for the problem according to the outcome record USB cable detected, and is analyzed the problem of record.Be specially the problem that electric current is excessive or current floating is excessive occurred according to the outcome record USB cable detected, and go out the qualification rate of USB cable in same production batch according to the interpretation of result of record.Wherein qualification rate is the ratio of qualified quantity/cable sum in same production batch.History Parser Module 104 can also record the time detected further.The data of physical record are preferably preserved with the form of excel form.
In sum, the present invention can realize the automatic test of USB cable performance, can require again to do over again after the qualification rate analyzing USB cable is not up to standard.To reduce the damage of USB cable charging equipment and terminal device.In addition, the present embodiment repeatedly can also be tested each USB cable, to reduce test error.Apparatus and method of the present invention can be applied to as in the middle of the electronic products such as mobile phone, camera, panel computer.
