Description
[technical field]
The utility model relates to USB flash disk, particularly relates to a kind of test USB flash disk.
[background technology]
For electronic products such as notebook computers, it can have usually several USB (Universal SerialBus, USB (universal serial bus)) interface.The current USB interface be located on electronic product is all USB3.0 interface usually, before electronic product dispatches from the factory, can carry out testing to guarantee that the function of each interface is qualified.Whether for the interface of USB3.0, in order to backward compatible, not only need to test it and connect USB3.0 equipment and can normally work, can also need to test the equipment connecting USB2.0 normally work.USB2.0 equipment can use one group of transmission (transport), receive (receive) pin, and USB3.0 equipment can use two groups of transmissions, receive pin.
Current test mode adopts the equipment (being such as USB flash disk) of the equipment of USB2.0 (being such as USB flash disk), USB3.0 to carry out USB2.0, USB3.0 functional test to the USB interface of described electronic product respectively, therefore need to use different USB device when testing, and need to carry out twice plug.
Visible, adopt above-mentioned test mode, plug often, test process bothers, expend man-hour and easily cause plug to damage; Meanwhile, need use two class USB flash disk, cause unnecessary waste.
In view of this, be necessary to develop a kind of test USB flash disk, to solve the problem in fact.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of test USB flash disk, solves when USB2.0 and the USB3.0 function of test computer board, needs to insert USB2.0U dish and USB3.0U dish respectively, plugs often, test process trouble, the problem expending man-hour.
In order to achieve the above object, the test USB flash disk that the utility model provides, comprising:
Internal circuit, it draws two USB2.0 signal pins, four USB3.0 signal pins;
USB interface, its side is connected with the external world, and opposite side has two USB2.0 signal pins, four USB3.0 signal pins, is also connected by power pins between described USB interface with described internal circuit;
Slide block, its two ends have four contacts respectively, described slide block slides to first direction, four contacts at described slide block two ends connect one to one with four USB3.0 signal pins of described internal circuit and described USB interface respectively, described slide block slides in the opposite direction to described first party, and two in four contacts at described slide block two ends connect one to one with two USB2.0 signal pins of described internal circuit and described USB interface respectively.
Optionally, described power pins comprises positive 5V pin and grounding pin.
Compared to prior art, utilize test USB flash disk of the present utility model, by to skid, the contact of slide block is connected with USB2.0 signal pins or USB3.0 signal pins respectively, thus complete the switching of described test USB flash disk between USB2.0 and USB3.0 function, thus adopt this test USB flash disk can complete the test of USB2.0, USB3.0 two kinds of functions of the USB interface treating tester table, what avoid employing two kinds of USB device (USB flash disk) repeatedly plugs the plug damage caused, and operational trouble, save man-hour.
[accompanying drawing explanation]
Fig. 1 illustrates the structural representation into test USB flash disk one of the present utility model preferred embodiment.
[embodiment]
Refer to Fig. 1, Fig. 1 illustrates the structural representation into test USB flash disk one of the present utility model preferred embodiment.
In order to achieve the above object, the test USB flash disk that the utility model provides, comprising:
Internal circuit 100, it draws two USB2.0 signal pins, 101 ~ 102, four USB3.0 signal pins 103 ~ 106;
USB interface 200, its side is connected with the external world, and opposite side has two USB2.0 signal pins, 201 ~ 202, four USB3.0 signal pins 203 ~ 206, is also connected by power pins between described USB interface 200 with described internal circuit 100;
Slide block 300, its two ends have four contacts 301 respectively, four contacts 301 and four contacts 301 of the other end of described slide block 300 one end connect one to one respectively (for avoiding drawing lines too much to cause chaotic reason not illustrate in Fig. 1), when described slide block 300 slides to first direction, four contacts 301 at described slide block 300 two ends respectively with four USB3.0 signal pins 103 ~ 106 of described internal circuit 100 and described USB interface 200, 203 ~ 206 connect one to one, when described slide block 300 slides in the opposite direction to described first party, two in four contacts 301 at described slide block 300 two ends respectively with two USB2.0 signal pins 101 ~ 102 of described internal circuit 100 and described USB interface 200, 201 ~ 202 connect one to one.
Wherein, described power pins can for comprising positive 5V pin 107 and grounding pin 108.
Utilize test USB flash disk of the present utility model, by sliding to slide block 300, the contact 301 making slide block 300 respectively with USB2.0 signal pins 101 ~ 102, 201 ~ 202 or USB3.0 signal pins 103 ~ 106, 203 ~ 206 connect, thus complete the switching of described test USB flash disk between USB2.0 and USB3.0 function, thus adopt this test USB flash disk can complete the USB2.0 of the USB interface treating tester table, the test of USB3.0 two kinds of functions, what avoid employing two kinds of USB device (USB flash disk) repeatedly plugs the plug damage caused, and operational trouble, save man-hour.
Be pointed out that; the utility model is not limited to above-mentioned embodiment; any simple modification that any those skilled in the art do above-described embodiment based on technical solutions of the utility model, equivalent variations and modification, all fall in protection domain of the present utility model.
