Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to a hub capable of performing multiple function tests without plugging or unplugging. Background Art

[0002] With the rapid development of electronic technology, various electronic products have been widely used in all aspects of life and production. In order to realize the sharing of resource information and convenient storage of data, data storage and transmission between digital products and their external connected devices are particularly important. Among them, USB 2.0 and USB 3.0 are commonly used data transmission standards. As a high-speed USB, USB 2.0 can theoretically transmit at a speed of up to 480Mbps, but in practice, due to the sharing of channels by devices, the speed is often lower than 30MB / s. A significant advantage of USB 2.0 is that it supports the connection of up to 127 devices, which allows users to easily connect more peripherals and digital products. Specifically, USB 2.0 can be used to connect digital products to realize data transmission and charging functions; it can connect various peripherals such as mouse, keyboard, printer, scanner, etc.; it can also connect various storage devices such as U disk, mobile hard disk, solid-state hard disk, etc., to realize data storage and transmission functions. USB 3.0, the full name of which is USB 3.0SuperSpeed, has a theoretical maximum transmission rate of 5.0Gbps / second, which is more than 10 times faster than USB 2.0. In addition, the power transmission function of USB 3.0 is also more powerful, which can provide more power support for devices, allowing some high-power devices to run better. At the same time, USB 3.0 maintains good compatibility, is compatible with USB 2.0 / 1.1 devices, and provides better performance for these devices. In addition, USB 3.0 supports more connection ports, which can connect more devices at the same time, making it more convenient to use multiple devices at the same time.

[0003] The transmission speed of USB3.0 is much higher than that of USB2.0. If the key function of the product depends on high-speed data transmission, then USB3.0 testing is essential. However, if the main function of the product is low-speed data transmission or simple power supply, then only USB2.0 testing may be required. Different markets may have different requirements for USB versions. Some emerging markets may still use USB2.0 devices, while mature markets may have widely adopted USB3.0. According to the specific needs of the target market, the corresponding test version needs to be selected.

[0004] However, from a quality assurance perspective, comprehensive testing of the product (including USB2.0 and USB3.0) can ensure that it can provide reliable performance in various situations. This helps reduce customer complaints or returns due to compatibility issues or insufficient performance. From a product design perspective, if the product is designed to support both USB2.0 and USB3.0, then it is obvious that both standards need to be tested. This ensures that the product can work properly when connected to different versions of the USB interface.

[0005] However, in today's market, hubs that can be used for product testing are generally divided into 2.0 hubs and 3.0 hubs, which are set up separately. After testing the 2.0 function, testers need to unplug the USB product and then plug it into the 3.0 hub for further testing. The operation is cumbersome and time-consuming, resulting in a large waste of manpower and time.

[0006] The above problems need to be solved urgently. Utility Model Content

The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Because the sixteen-port hub can provide multiple USB interfaces, it is equivalent to adding an extra sixteen USB interfaces to the computer. It is suitable for USB products that can copy videos, files, music and other data, such as U disks, card readers, mobile phones, tablets, etc. These USB products need to be tested before leaving the factory. In large-scale mass production tests, the sixteen-port hub is the first choice.

[0029] Currently, most hubs from conventional manufacturers are for home use or can only meet personal needs, so the sixteen-port hub is specially designed and prepared for factory testing and mass production. It can operate continuously and stably under high load conditions to improve testing efficiency. It is also called an industrial-grade sixteen-port hub, which can meet various testing requirements of the source factory.

[0030] However, although the existing test hubs can meet the needs of professional testing and mass production, it is well known that USB products can be divided into 2.0 and 3.0 functions, and the corresponding transmission rates and functions are also different. Most of the 16-port test hubs on the market are divided into two types, one is a 2.0 16-port hub, and the other is a 3.0 16-port hub. Each corresponding test of 2.0 and 3.0 functions requires plugging and unplugging products. It is time-consuming and labor-intensive to plug USB products into 2.0 or 3.0 hubs for testing, which is a considerable burden on manpower and material resources. In addition, frequent plugging and unplugging also has a great impact on the life of the hub. Frequent plugging and unplugging, affected by time, environment, human factors, etc., makes the hub easy to be scrapped, which is also time-consuming and labor-intensive, and the cost expenditure is very high.

[0031] like Figure 1 and Figure 2As shown, the present application provides an embodiment of a hub that can perform multiple functional tests without plugging and unplugging. The hub that can perform multiple functional tests without plugging and unplugging includes a shell 100, a test circuit board 200 is fixed in the shell 100, and the test circuit board 200 is provided with a USB2.0 interface 210, a USB3.0 interface 220, a first switch 230, a second switch 240 and multiple test interfaces 250; the USB2.0 interface 210 is used for USB2.0 functional test data transmission connection, and the USB3.0 interface 220 is used for USB3.0 functional test data transmission connection. The first switch 230 is electrically connected to the USB2.0 interface 210 for controlling the on and off of the USB2.0 functional test circuit, and the second switch 240 is electrically connected to the USB3.0 interface 220 for controlling the on and off of the USB3.0 functional test circuit. To ensure the smooth progress of the detection, the first switch 230 and the second switch 240 will not be turned on at the same time. A USB2.0 test circuit and a USB3.0 test circuit are respectively set on a hub, and the circuit selection is controlled by the first switch 230 and the second switch 240. When performing a product transmission standard test, it is only necessary to control the opening and closing of the first switch 230 and the second switch 240 on the hub to complete the switching of different test standard circuits. There is no need to unplug the product to be tested from one test hub and plug it into another test hub. The first and second switches 240 can be used to control the test of USB2.0 and 3.0 without plugging in or out the product, thereby reducing the plugging and unplugging process, reducing the test time, and reducing the labor cost. In addition, reducing the frequent plugging and unplugging of products also helps to reduce the wear on the test interface 250 during the plugging and unplugging process, which helps to extend the service life of the hub and reduce the test cost.

[0032] In one embodiment, the housing 100 includes a lower housing 120 and an upper housing 110, wherein the upper housing 110 covers the lower housing 120; the upper housing 110 is provided with a plurality of plug holes 1101 corresponding to the test interface 250, and the product to be tested is plugged into the test interface 250 after passing through the plug holes 1101; the side of the lower housing 120 is provided with a plurality of connection holes 1201 corresponding to the USB2.0 interface 210 and the USB3.0 interface 220, and the connection holes 1201 are used for the USB2.0 connector to be plugged into the USB2.0 interface 210, or for the USB3.0 connector to be plugged into the USB3.0 interface 220. The upper and lower housing designs facilitate the assembly and disassembly of the hub.

[0033] In one embodiment, the upper shell 110 is transparent. On the test circuit board 200 , each test interface 250 is provided with an LED lamp bead near the test interface 250 . The LED lamp bead displays different colors to show whether the product to be tested plugged into the test interface 250 is qualified.

[0034] In the above embodiment, the upper shell 110 is made of black translucent material. The upper shell 110 and the lower shell 120 are both made of plastic. The black translucent material facilitates the light transmission observation of the LED lamp beads, and the black translucent material has good light conductivity. The plastic shell 100 is not only cheap and easy to obtain, but also helps to reduce the weight of the hub, making it convenient for mobile use.

[0035] like Figure 2 As shown, in one embodiment, a plurality of first fixing columns 1102 are provided on the bottom surface of the upper shell 110, and a plurality of second fixing columns 1202 are correspondingly provided on the bottom surface of the lower shell 120. The first fixing columns 1102 and the second fixing columns 1202 abut against the test circuit board 200, and screws pass through the test circuit board 200 to connect the first fixing columns 1102 and the second fixing columns 1202 at corresponding positions, thereby fixing the test circuit board 200 in the housing 100. In the figure, there are eight first fixing columns 1102, eight second fixing columns 1202 and eight screws, and they are arranged in a 2×4 array. The test circuit board 200 is suspended so that it does not directly contact the housing 100, which facilitates the heat dissipation of the test circuit board 200, helps stabilize the temperature in the housing 100, and prevents the test circuit board 200 from malfunctioning due to local overheating.

[0036] In one embodiment, the USB 2.0 interface 210 and the USB 3.0 interface 220 are located on the same side of the test circuit board 200, and the connection hole 1201 is also located on the same side of the lower shell 120. The USB 2.0 interface 210 and the USB 3.0 interface 220 are concentrated on the same side to facilitate the access of various connection lines.

[0037] In one embodiment, a plurality of heat dissipation holes 1203 are provided on the side of the lower shell 120. The heat dissipation holes 1203 facilitate the air flow inside and outside the shell 100. The plurality of heat dissipation holes 1203 are designed around the hub, so that the hub can dissipate heat well under high load, prevent high temperature, protect the test circuit board 200, and extend the service life of the hub.

[0038] like Figure 1 As shown, in one embodiment, the first switch 230 and the second switch 240 are both toggle switches. The toggle switch, the USB2.0 interface 210 and the USB3.0 interface 220 are located on the same side of the housing 100. The on-off control of the USB2.0 test circuit and the on-off control of the USB3.0 test circuit can be realized by sliding the sliding button on the toggle switch left and right. The control method is simple and convenient.

[0039] In one embodiment, a power socket 260 is provided on the test circuit board 200, and the power socket 260 is used to connect the test circuit board 200 to a power source. The power socket 260 is connected to a power source through a power line to power the device. In the figure, there are two power sockets 260, and only one power socket 260 needs to be connected to the power source during testing, and the other power socket 260 is reserved.

[0040] The working process of the hub that can perform multiple functional tests without plugging and unplugging is as follows:

[0041] When in use, the external power cord is plugged into the power socket 260, so that the hub that can perform multiple function tests without plugging and unplugging is powered on, and then the hub is connected to the computer through the USB2.0 interface 210 and the USB3.0 interface 220 with data cables, and the USB product to be tested is plugged into the test interface 250, and the toggle switch near the USB2.0 interface 210 is toggled. At this time, if the LED light on the test circuit board 200 is always green, it means that the 2.0 function is normal, and if it is red, it means that a certain USB product is abnormal. Then the toggle switch near the USB3.0 interface 220 is toggled to test the 3.0 function. Similarly, if the LED light is green, it means that the overall data transmission is normal, and red means abnormal.

[0042] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0043] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
