Description
Technical field
The utility model relates to electron product checking device, particularly a kind of USB interface testing tool.
Background technology
In recent years, the electronic equipment that has USB port is more and more, and after USB device was connected to the USB port of electronic equipment, whether electronic equipment at first detected USB device and be connected on its USB port, could realize the exchanges data with USB device then.
In order to guarantee that USB port can operate as normal, when electronic equipment factory inspection and daily servicing, often need the quality problem of testing USB port, promptly check whether compliant of its supply voltage and electric current, and check whether its transmission data performance is good.Common method of testing is to utilize USB devices such as the mouse have USB interface, keyboard, portable hard drive, printer to accomplish; When the some USB ports of test; Need each USB device be inserted said USB port respectively; Check the existence that whether can normally detect all USB devices through the autotest program of electronic equipment again, promptly whether all USB devices can operate as normal.
And the testing tool of this method utilization is required to be USB devices such as the multiple mouse that has a USB interface, keyboard, portable hard drive, printer; Their major function is not the quality problem that is used for testing USB port; Its major function is not utilized; Many electric idle with the mechanical part quilt, waste the resource of these equipment, thereby caused testing cost higher.Test duration while is longer, and the wasting manpower and material resources is also directly perceived inadequately.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of USB interface testing tool, and lower to reach testing cost, the test duration is shorter, use manpower and material resources sparingly, and intuitive and reliable purpose.
For achieving the above object, the technical scheme of the utility model is following: a kind of USB interface testing tool comprises electric cabinet, attaching plug and USB port; Said electric cabinet inside is provided with circuit board, and casing is provided with pilot lamp; Said attaching plug, USB port, pilot lamp and said circuit board electrically connect.
Preferably, said pilot lamp has seven, comprises two power lights and five test pilot lamp.
Preferably, said circuit board output voltage is 5V, and gives the power supply of test pilot lamp.
Preferably, said attaching plug is that circuit board is given in alternating current 220V input power supply, and supplies power to power light.
Preferably, said electric cabinet is provided with bat-handle switch.
Through technique scheme, the USB interface testing tool that the utility model provides, through being provided with circuit board in said electric cabinet inside, casing is provided with pilot lamp; Said attaching plug, USB port, pilot lamp and said circuit board electrically connect; After attaching plug connected external power source, when USB joint to be measured inserted USB port, whether the observation test pilot lamp is shinny detected USB joint to be measured; Thereby it is lower to have reached testing cost; Test duration is shorter, uses manpower and material resources sparingly, and intuitive and reliable purpose.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the plan structure synoptic diagram of the disclosed a kind of USB interface testing tool of the utility model embodiment;
