Description

U disk for testing

【Technical field】

The utility model relates to a U disk, in particular to a U disk for testing.

【Background technique】

For electronic products such as notebook computers, there are usually several USB (Universal Serial Bus, universal serial bus) interfaces on it. The current USB interfaces on electronic products are usually USB3.0 interfaces. Before the electronic products leave the factory, tests will be carried out to ensure that the functions of each interface are qualified. For the USB3.0 interface, in order to be backward compatible, it is necessary not only to test whether it can work normally when connected to USB3.0 devices, but also to test whether the devices connected to USB2.0 can work normally. USB2.0 devices will use a set of send (transport) and receive (receive) pins, while USB3.0 devices will use two sets of send and receive pins.

The current test method is to use USB2.0 equipment (such as U disk), USB3.0 equipment (such as U disk) to carry out USB2.0 and USB3.0 functional tests on the USB interface of the electronic product respectively, so Different USB devices need to be used during the test, and two plugging and unplugging are required.

It can be seen that, with the above test method, the number of plugging and unplugging is large, the testing process is cumbersome, time-consuming and easy to cause plugging damage; at the same time, two types of U disks need to be used, resulting in unnecessary waste.

In view of this, it is necessary to develop a USB flash drive for testing to solve the above problems.

【Content of invention】

Therefore, the purpose of this utility model is to provide a kind of testing U disk, solve when testing the USB2.0 and USB3.0 function of computer machine, need to insert USB2.0 U disk and USB3. , The testing process is cumbersome and time-consuming.

In order to achieve the above object, the testing U disk provided by the utility model includes:

Internal circuit, which leads to two USB2.0 signal pins and four USB3.0 signal pins;

USB interface, one side of which is connected to the outside world, and the other side has two USB2.0 signal pins and four USB3.0 signal pins, and the USB interface is also connected to the internal circuit through a power supply pin ;

The slider has four contacts at both ends, and the slider slides in the first direction. The four contacts at the two ends of the slider are respectively connected to the internal circuit and the four USB3.0 ports of the USB interface. The signal pins are connected in one-to-one correspondence, the slider slides in a direction opposite to the first direction, and two of the four contacts at both ends of the slider are respectively connected to the internal circuit and the two contacts of the USB interface. The USB2.0 signal pins are connected in one-to-one correspondence.

Optionally, the power pins include a positive 5V pin and a ground pin.

Compared with the prior art, using the U disk for testing of the utility model, by sliding the slider, the contacts of the slider are respectively connected to the USB2.0 signal pins or the USB3.0 signal pins, thereby completing the testing of all Describe the switching between USB2.0 and USB3.0 functions of the test U disk, so that the test U disk can be used to complete the test of the USB2.0 and USB3.0 functions of the USB interface of the machine to be tested. The plugging damage caused by multiple plugging and unplugging of two kinds of USB devices (U disks) and troubles in operation are avoided, and man-hours are saved.

【Description of drawings】

FIG. 1 is a schematic structural diagram of a preferred embodiment of a testing U disk of the present invention.

【Detailed ways】

Please refer to FIG. 1 . FIG. 1 is a schematic structural diagram of a preferred embodiment of a testing U disk of the present invention.

In order to achieve the above object, the testing U disk provided by the utility model includes:

An internal circuit 100, which leads to two USB2.0 signal pins 101-102 and four USB3.0 signal pins 103-106;

One side of the USB interface 200 is connected to the outside world, and the other side has two USB2.0 signal pins 201-202, four USB3.0 signal pins 203-206, the USB interface 200 and the internal circuit 100 are also connected through the power pin;

The slider 300 has four contacts 301 at its two ends respectively, and the four contacts 301 at one end of the slider 300 are respectively connected to the four contacts 301 at the other end one by one (in FIG. Too many causes of confusion are not shown), when the slider 300 slides in the first direction, the four contacts 301 at both ends of the slider 300 are connected to the four contacts of the internal circuit 100 and the USB interface 200 respectively. USB3.0 signal pins 103-106, 203-206 are connected in one-to-one correspondence. One is respectively connected to the internal circuit 100 and the two USB2.0 signal pins 101-102, 201-202 of the USB interface 200 in a one-to-one correspondence.

Wherein, the power supply pin may include a positive 5V pin 107 and a ground pin 108 .

Using the U disk for testing of the utility model, by sliding the slider 300, the contacts 301 of the slider 300 are respectively connected to the USB2.0 signal pins 101-102, 201-202 or USB3.0 signal pins 103-106 , 203 to 206 connections, thereby completing the switching between the USB2.0 and USB3.0 functions of the USB flash drive for testing, thus using the USB flash drive for testing to complete the USB2.0 USB interface of the test machine. , USB3.0 two function tests, avoiding the plugging and unplugging damage caused by multiple plugging and unplugging of two USB devices (U disks), as well as troubles in operation, saving man-hours.
