[0001] The utility model relates to the technical field of testing devices, in particular to a testing system with multiple USB function tests. Background Art

[0002] In the current market, USB products are everywhere. From USB flash drives to card readers, from mobile phones to tablets, to HUBs that connect multiple devices, these USB products have won wide industry recognition and user favor with their portability and efficient data transmission capabilities. Whether in the office or in home entertainment, they play an indispensable role, helping people easily transfer and share important information such as videos, files, and music. With the continuous advancement of technology, the demand for USB products is also increasing, and the market volume has shown explosive growth. In such a market context, the stability and reliability of product quality have become the focus of consumers. In order to meet this demand, most conventional manufacturers will conduct a series of detailed functional tests before USB products leave the factory. These tests include data transmission speed, interface compatibility, power consumption and other aspects, aiming to ensure that the product can operate stably in various environments and provide consumers with a high-quality user experience.

[0003] However, in the existing test product field, although they can meet the basic needs of professional testing and mass production, most of the test equipment on the market cannot take into account both USB 2.0 and 3.0 products. Due to the significant differences in transmission rate and function between USB 2.0 and 3.0, existing test equipment can usually only test one of the standards. Therefore, during the test process, manufacturers need to frequently replace test equipment or adjust the test interface (such as plugging USB products into 2.0 or 3.0 hubs), which not only increases the complexity of the test, but also reduces the test efficiency, making the entire test process time-consuming and laborious.

[0026] like Figure 1As shown, the present application provides an embodiment of a test system with multiple USB function tests, and the test system with multiple USB function tests includes a tester 100, a multi-port hub 200 and an industrial computer 300. The tester 100 is provided with a USB connection plug 110, and the USB connection plug 110 is connected to a test circuit board inside the tester 100, and the test circuit board has a USB2.0 test circuit and a USB3.0 test circuit; the multi-port hub 200 is provided with multiple USB test sockets; the industrial computer 300 is equipped with USB function test software; the multi-port hub 200 is connected to the industrial computer 300 by a data line, and the USB product 500 to be tested is plugged into the USB test socket of the multi-port hub 200, and the USB connection plug 110 is plugged into the USB product 500 to be tested. The tester 100, the USB product to be tested, the multi-port hub 200 and the industrial computer 300 are connected in sequence to form a complete USB function test circuit, so as to perform USB2.0 function test and / or USB3.0 function test on the USB product 500 to be tested. When in use, the multi-port hub 200 is connected to the industrial computer 300 via a data cable, the tester 100 is plugged into the USB product 500 to be tested, the USB product 500 to be tested is plugged into the USB test port, the tester 100, the USB product to be tested, the multi-port hub 200 and the industrial computer 300 are connected in sequence to form a complete USB function test circuit, the tester 100 and the multi-port hub 200 are independent of each other, and two USB function test circuits are arranged in the tester 100. After the product to be tested is inserted into the multi-port hub 200, the test software in the tester 100 and the industrial computer 300 cooperate to implement the test of the USB2.0 function and the USB3.0 function of the USB product, so as to achieve the purpose of completing the USB2.0 function and the USB3.0 function test without plugging and unplugging the USB product, reduce the frequent plugging and unplugging times during product testing, save manpower and reduce time consumption, and help reduce the cost of USB product testing. The tester 100 of the utility model controls the functions of 2.0 and 3.0 through the mainboard integration. Correspondingly, the tester 100 product needs to be plugged into the USB product interface for functional testing. It can be used with a multi-port hub to test multiple products at one time, thereby improving work efficiency and saving costs.

[0027] like Figure 2As shown, in one embodiment, the tester 100 is provided with an indicator light 120, and the indicator light 120 is a 0603 patch light. When the test is performed, the 2.0 or 3.0 functional test is performed on the product to be tested in sequence according to the test software setting in the industrial computer 300. When the USB product 500 to be tested plugged into the multi-port hub 200 is functioning normally, the indicator light 120 lights up with the set first prompt color. When the USB product 500 to be tested has an abnormal USB function, the indicator light 120 lights up with the second prompt color, and the colors of the first prompt color and the second prompt color are different. Generally, the first prompt color is green and the second prompt color is red. Green is a safety color, and red is a warning color. The normal and abnormal color settings are in line with general life cognition and are easy to distinguish. Sometimes the color of the prompt color can also be changed according to the use requirements. Only when the two prompt colors of the indicator light 120 are green, that is, the test results are normal, the product to be tested is a qualified product. Abnormal conditions require specific analysis.

[0028] like Figure 2 As shown, in one embodiment, the tester 100 further includes a tester cap 130. The tester cap 130 is a cavity structure with one end open. The tester cap 130 is snapped onto the outer shell of the tester 100 to form a closed protective cavity. The USB connection plug 110 is located in the protective cavity. The tester 100 exists independently. The tester cap 130 protects the USB connection plug 110 on the tester 100 during non-working hours, prevents damage to the USB connection plug 110, and helps to extend the service life of the tester 100.

[0029] like Figure 3 As shown, in one embodiment, within the tester 100, the USB2.0 test circuit and the USB3.0 test circuit are connected in parallel, the VBUS pin of the USB connection plug 110 is electrically connected to the power lines of the USB2.0 test circuit and the USB3.0 test circuit respectively, and the GND pin of the USB connection plug 110 is electrically connected to the ground lines of the USB2.0 test circuit and the USB3.0 test circuit respectively.

[0030] In one embodiment, the multi-port hub 200 is a sixteen-port HUB hub 200. The sixteen-port HUB hub has sixteen USB sockets, and can perform USB2.0 functional tests and USB3.0 functional tests on up to sixteen USB products 500 to be tested at one time. When testing a large number of products, it is necessary to wait for a certain period of time when testing USB2.0 and 3.0 functions. Then, at this time, 16 products that need to be functionally tested can be plugged into the sixteen-port HUB hub at the same time. With the tester 100, multiple products can be functionally tested at the same time to avoid low efficiency. At the same time, the tester does not need to replace the product to be tested immediately after the test of a single product is completed. The USB sockets on the multi-port hub 200 can be filled with the products to be tested at one time, and the detection time and product plug-in and unplug time are concentrated, which helps to improve the attention of the tester and helps to reduce human testing errors.

[0031] In one embodiment, a workbench 400 is further included, and the display screen of the industrial computer 300 and the multi-port hub 200 are placed on the workbench 400. The workbench 400 provides a placement location for the industrial computer 300 and the multi-port hub 200, and the product to be tested can also be placed on the workbench 400, which facilitates the testing work.

[0032] The tester 100 of the utility model is inserted into the product that needs to test the USB function, and can test the 2.0 and 3.0 functions at the same time, realizing dual functions and saving a lot of costs. When matched with the multi-port hub 200, multiple products that need to be tested for USB 2.0 and 3.0 functions can be tested at the same time, greatly improving work efficiency and saving a lot of costs for enterprises.
