Abstract
A USB testing device for testing the antistatic property of USB port, comprising a USB joint for plugging the USB port, at least one testing portion capable of exerting high-voltage electrostatic and a wire connecting the USB port and the testing portion. The USB testing device is capable of test the antistatic property expediently.
Description
Technical field
The utility model relates to a kind of USB (Universal Serial Bus) proving installation, particularly about a kind of can Validity Test the device of antistatic property of USB port.
Background technology
The equipment of present various USB port is very universal, as camera, and portable hard drive, printer or the like.The advantage of USB is can charged hot plug, but also just because the hot plug of USB, the user is contact USB system often, so just very strong static discharge may occur.
Human body generally can carry static more or less, and when the contact electronic component, the transient voltage of generation can reach several kilovolts, owing to static discharge produces high pressure, may cause electronic component to burn, and the USB controller is just in south bridge, so may cause south bridge to burn.
Therefore, in actual production, USB port is usually made some electrostatic tests, the simulation human body is to the static discharge of USB port, the antistatic property of testing USB port.
The common electrostatic discharge testing to USB port is by the incoming line input high-tension electricity of a static gun to USB port, antistatic property with test USB circuit, because the opening finite volume of USB port, static gun may not reach the incoming line in the USB port, thereby influences the test of the antistatic property of USB port.
Summary of the invention
In view of above content, be necessary to provide a kind of USB proving installation of being convenient to the antistatic property of testing USB port.
A kind of USB proving installation is used for the antistatic property of testing USB port, and described proving installation comprises that be used to the to peg graft USB joint of USB port, at least one test department and that applies high-pressure electrostatic connects the lead of described USB joint and described test department.
Compared to prior art, described proving installation comprises be used to peg graft the USB joint of USB port and the test department of the described USB joint of at least one connection, can reach the purpose of testing USB port by testing described test department during test, and is simple, convenient.
Description of drawings
The utility model will be further described in conjunction with embodiment with reference to the accompanying drawings.
Fig. 1 is that the utility model preferred embodiment USB proving installation connects block diagram.
Embodiment
See also Fig. 1, the utility model preferred embodiment USB proving installation comprises that the mount board 40 and that the USB joint 10 of USB jack, four test departments 20, four resistance 30, one is used for described test department 20 of device and described resistance 30 that is used to peg graft can apply the static gun 60 of high-pressure electrostatic to described test department 20, the USB cable that connects described USB joint 10 has four leads 50, each lead 50 connects a test department 20, each test department 20 connects an end of a described resistance 30, the other end ground connection of described resistance 30.
During test, earlier described USB joint 10 is plugged on the USB port of a mainboard, on described test department 20, apply high-pressure electrostatic with described static gun 60, described high-pressure electrostatic can be transferred on the USB port of described computer main board by lead 50, if the electrostatic potential that static gun applies is too high, described static can be transferred to the earth by described resistance 30.
The above is only for being used to explain preferred embodiment of the present utility model, and all changes of under identical creative spirit the utility model being done and any modification all should be encompassed in the scope that the utility model protects.
