Abstract
The invention discloses a USB (Universal Serial Bus) disk used for test. The USB disk comprises an internal circuit, a USB interface and a sliding block, wherein the internal circuit leads two USB2.0 signal pins and four USB3.0 signal pins; one side of the USB interface is connected with outside, the other side of the USB interface is provided with two USB2.0 signal pins and four USB3.0 signal pins; two ends of the sliding block are independently provided with four contacts; and the sliding block slides to a first direction, four contacts on two ends of the sliding block are independently connected with the four USB3.0 signal pins of the internal circuit and the the four USB3.0 signal pins of the USB interface one by one, the sliding block slides to a direction opposite to the first direction, and two of the four contacts on two ends of the sliding block are independently connected with the two USB2.0 signal pins of the internal circuit and the two USB2.0 signal pins of the USB interface one by one. Plugging damage and operation trouble caused by that two types of USB disks are adopted to carry out multiple-time plugging can be avoided.
Description
[technical field]
The present invention relates to USB flash disk, particularly relate to a kind of test USB flash disk。
[background technology]
For electronic products such as notebook computers, it would generally have several USB (UniversalSerialBus, USB (universal serial bus)) interface。The current USB interface being located on electronic product is generally all USB3.0 interface, and before electronic product dispatches from the factory, the function that can carry out testing to guarantee each interface is qualified。For the interface of USB3.0, in order to backward compatible, not only need to test its connect USB3.0 equipment whether can normal operation, in addition it is also necessary to can test connects the equipment of USB2.0 normal operation。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 be adopt the equipment (such as USB flash disk) of USB2.0, the USB interface of described electronic product is carried out USB2.0, USB3.0 functional test by the equipment (such as USB flash disk) of USB3.0 respectively, therefore need to use different USB devices when test, and need to perform twice at plug。
Visible, adopt above-mentioned test mode, often, test process bothers, expends man-hour and easily cause plug damage in plug；Simultaneously, it is necessary to use two class USB flash disks, cause unnecessary waste。
In view of this, it is necessary in fact to develop a kind of test USB flash disk, to solve the problems referred to above。
[summary of the invention]
Therefore, it is an object of the invention to provide a kind of test USB flash disk, solve when testing USB2.0 and the USB3.0 function of computer board, it is necessary to insert USB2.0U dish and USB3.0U dish respectively, plug often, test process trouble, the problem expending man-hour。
In order to achieve the above object, test USB flash disk provided by the invention, including:
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 connected also by power pins between described USB interface with described internal circuit；
Slide block, its two ends are respectively provided with four contacts, 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 to described first direction opposite direction, 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 includes positive 5V pin and grounding pin。
Compared to prior art, utilize the test USB flash disk of the present invention, by to skid, the contact making slide block is connected with USB2.0 signal pins or USB3.0 signal pins respectively, thus completing the switching between USB2.0 and USB3.0 function of the described test USB flash disk, thus adopting this test USB flash disk can complete to treat the test of two kinds of functions of USB2.0, USB3.0 of the USB interface of tester table, avoid and adopt the plug caused that repeatedly plugs of two kinds of USB devices (USB flash disk) to damage, and operational trouble, save man-hour。
[accompanying drawing explanation]
Fig. 1 is schematically shown as the structural representation of test USB flash disk one preferred embodiment of the present invention。
[detailed description of the invention]
Refer to the structural representation that Fig. 1, Fig. 1 are schematically shown as test USB flash disk one preferred embodiment of the present invention。
In order to achieve the above object, test USB flash disk provided by the invention, including:

USB interface 200, its side is connected with the external world, and opposite side has 201～202, four USB3.0 signal pins 203～206 of two USB2.0 signal pins, is connected also by power pins between described USB interface 200 with described internal circuit 100；
Slide block 300, its two ends are respectively provided with four contacts 301, four contacts 301 of described slide block 300 one end and four contacts 301 of the other end connect one to one (for avoiding drawing lines too much to cause the reason of confusion not illustrate in Fig. 1) respectively, described slide block 300 to first direction slide time, 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, described slide block 300 to described first direction opposite direction slide time, in four contacts 301 at described slide block 300 two ends two 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 including positive 5V pin 107 and grounding pin 108。
Utilize the test USB flash disk of the present invention, by slide block 300 is slided, make the contact 301 of slide block 300 respectively with USB2.0 signal pins 101～102, 201～202 or USB3.0 signal pins 103～106, 203～206 connect, thus completing the switching between USB2.0 and USB3.0 function of the described test USB flash disk, thus adopting this test USB flash disk can complete to treat the USB2.0 of the USB interface of tester table, the test of two kinds of functions of USB3.0, avoid and adopt the plug caused that repeatedly plugs of two kinds of USB devices (USB flash disk) to damage, and operational trouble, save man-hour。
It is noted that the invention is not restricted to above-mentioned embodiment, any simple modification, equivalent variations and the modification that above-described embodiment is made by any those skilled in the art based on technical solution of the present invention, both fall within protection scope of the present invention。
