Detailed Implementation

[0047] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the invention provides a hub device, including: a base 10, a first connecting assembly 20 having a circular first through hole 21, a cylindrical rotating member 30 having a circular second through hole 31, and a cylindrical second connecting assembly 40; the first through hole 21 penetrates through opposite ends of the first connecting assembly 20, and the second through hole 31 penetrates through opposite ends of the rotating member 30; the base 10 is connected to one end of the first connecting assembly 20, one end of the rotating member 30, and one end of the second connecting assembly 40, respectively; the rotating member 30 is disposed in the first through hole 21 of the first connecting assembly 20, and the second connecting assembly 40... The component 40 is disposed in the second through hole 31 of the rotating component 30; the rotating component 30 can rotate on the base 10; the first connection component 20 includes a plurality of access ports 22, each access port 22 for connecting a device under test (not shown in the figure); the second connection component 40 is used to connect to an external device (not shown in the figure); the side wall of the rotating component 30 has a conductive structure 32; when the rotating component 30 is rotated to the point where the conductive structure 32 is aligned with the target access port 22 among the plurality of access ports 22, the conductive structure 32 connects the target device under test connected to the target access port 22 and the external device.

[0049] In this embodiment of the invention, the base 10 of the hub device serves as a supporting core, on which a cylindrical first connecting component 20 is vertically mounted. A freely rotatable cylindrical rotating component 30 is nested within the circular first through-hole 21 of the first connecting component 20. A fixedly mounted second connecting component 40 is further installed within the second through-hole 31 of the rotating component 30. This coaxial nesting design allows the rotating component 30 to smoothly rotate 360° around the central axis of the second connecting component 40 on the base 10, thus forming a hub device that can be quickly switched via rotation.

[0050] When testing the functionality of external devices on a computer host, the tester first connects the second connection component 40 to the signal cable of the external device, which typically includes a monitor, mouse, keyboard, USB flash drive, printer, etc. Then, the different access ports 22 of the first connection component 20 are connected to the signal cables of each computer host to be tested. Next, the rotating component 30 is rotated until the conductive structure 32 on its side wall aligns with the target access port 22, connecting the external device to the target host, allowing for the testing of the external device's functionality. After testing, the rotating component 30 is rotated until the conductive structure 32 aligns with the next host under test, and the testing of the next host's external device functionality begins. Once all computer hosts connected to the hub have been tested, the signal cables of these computer hosts are disconnected from the access ports 22. Repeating the above steps allows for the testing of the external device functionality of the next batch of computer hosts.

[0051] For example, connect the connection cable of the first computer under test to the first target access port a1, the connection cable of the second computer under test to the second target access port a2, and the connection cable of the third computer under test to the third target access port a3. Connect the connection cables of external devices such as monitor, mouse, keyboard, USB flash drive, and printer to the second connection component. Rotate the rotating part 30 until the conductive structure 32 is aligned with the first target access port a1 connected to the connection cable of the first computer under test to perform the external device function test. After the test is completed, rotate the rotating part 30 until the conductive structure 32 is aligned with the second target access port a2 connected to the connection cable of the second computer under test to perform the external device function test of the second computer under test. Similarly, rotate the rotating part 30 until the conductive structure 32 is aligned with the third target access port a3 connected to the connection cable of the third computer under test to perform the external device function test of the third computer under test. After the three computer hosts connected to the hub have been tested, disconnect the signal cables of these three computer hosts from the access port 22, and proceed with the next batch of external device function tests for the computer hosts.

[0052] In summary, this embodiment of the invention, by setting multiple access ports and multiple conductive structures and aligning the conductive structures with different access ports through the rotation of a rotating component, enables the same external device to be connected to different computer hosts. This allows for rapid switching between connections between the same external device and multiple computer hosts. During testing, only rotation is required, eliminating the need for repeated plugging and unplugging of signal cables. By reducing mechanical operations, the human error rate during testing is lowered, thereby reducing testing complexity and improving testing efficiency. Furthermore, the multiple access ports design provides scalability for adding more devices under test, further expanding the application range of the device.

[0053] Meanwhile, the hub device provided in this embodiment of the invention establishes a connection by physically aligning the conductive structure of the rotating component with the access port. Since the alignment of the conductive structure with the access port has a clear mechanical positioning, the signal or data can remain stable during transmission, reducing transmission interruptions or data errors caused by connection problems, thereby ensuring the reliability of the connection between the device under test and the external device.

[0054] Furthermore, the rotating component is positioned within the first through hole of the first connecting assembly, while the second connecting assembly is positioned within the second through hole of the rotating component. This nested structure allows the components to be tightly integrated, enhancing the correlation and integrity between the components of the device, compressing the overall volume of the device, and improving the overall structural stability.

[0055] Optional, refer to Figure 3 The first connecting component 20 includes: a plurality of external fixing blocks 23 and a plurality of first electrical connectors 24; the plurality of external fixing blocks 23 are detachably connected to each other, each external fixing block 23 is provided with a plurality of third through holes 230, each third through hole 230 penetrates the external fixing block 23 along the radial direction X of the first connecting component 20, and the plurality of third through holes 230 are arranged at intervals along the axial direction Y of the first connecting component 20; each third through hole 230 is provided with a corresponding first electrical connector 24; the first electrical connector 24 provided in each third through hole 230 constitutes an access port 22.

[0056] The hub device in this embodiment of the invention includes 10 external fixing blocks 23, which can support connection cables to up to 10 computer hosts. These external fixing blocks 23 are detachably connected, allowing operators to flexibly increase or decrease the number of external fixing blocks 23 according to the number and type of computer hosts to be tested, easily expanding or simplifying the device. This allows the same external device to be conveniently connected to more numbers or different types of computer hosts, enhancing the applicability of the hub device.

[0057] The third through hole 230 penetrates the outer fixing block 23 radially X-axis of the first connecting assembly 20, allowing the first electrical connector 24 to be disposed within the third through hole 230. One end of the first electrical connector 24 can be electrically connected to the conductive structure 32, and the other end of the first electrical connector 24 forms the access port 22. Furthermore, the third through holes 230 are spaced apart along the axial Y-axis of the first connecting assembly 20, ensuring a one-to-one correspondence between the first electrical connector 24 within each third through hole 230 and the corresponding conductive structure 32 on the rotating member 30. When the rotating member 30 is rotated, the connection between the conductive structure 32 and the target first electrical connector 24 can be precisely achieved, thereby completing signal switching and transmission and providing a solid structural foundation for efficient testing.

[0058] Optional, refer to Figure 3 and Figure 4 Each external fixing block 23 has a snap-fit ​​groove 231 on one side and a snap-fit ​​block 232 on the opposite side. The snap-fit ​​groove 231 and the snap-fit ​​block 232 cooperate with each other to form a detachable connection between multiple external fixing blocks 23. Each first electrical connector 24 is fitted with a corresponding first spring 240, and each first spring 240 is coaxially arranged with the corresponding first electrical connector 24. Each external fixing block 23 is provided with a fourth through hole 233, which penetrates the external fixing block 23 along the axial direction Y of the first connecting assembly 20. Multiple first electrical connectors 24 fitted with first springs 240 are placed in the fourth through hole 233.

[0059] In this embodiment of the invention, the detachable connection between the external fixing blocks 23 is achieved through a snap-fit ​​structure: the snap-fit ​​block 232 on one side of each external fixing block 23 can be embedded into the corresponding snap-fit ​​groove 231 on the other side of the adjacent external fixing block 23. This structural design ensures the stability of multiple external fixing blocks 23 when spliced, making the overall structure less prone to loosening during use. At the same time, operators can easily install and disassemble the external fixing blocks 23. When it is necessary to adjust the number of access ports 22 to adapt to different testing requirements, only the number of external fixing blocks 23 needs to be increased or decreased, without the need for complex tools, which improves the convenience of operation and the flexibility of the device.

[0060] Meanwhile, since the first spring 240 and the first electrical connector 24 are coaxially arranged, when the first spring 240 is in its natural state or rebounds after being compressed, it can generate a continuous and stable thrust on the first electrical connector 24 along the radial X-direction rotating member 30, pushing the first electrical connector 24 out toward the rotating member 30. This design eliminates gaps caused by installation errors or long-term use, ensuring that the first electrical connector 24 and the conductive structure 32 always maintain a tight connection, reducing contact problems during signal transmission, ensuring stable transmission of test signals, and providing a reliable guarantee for the accuracy of test results.

[0061] Optional, refer to Figure 5 Each first electrical connector 24 has a first terminal 241 at one end, which is used to connect to the connection line of the device under test; and a spherical protrusion contact 242 at the opposite end of each first electrical connector 24.

[0062] In this embodiment of the invention, the first terminal 241 at one end of the first electrical connector 24 serves as an interface for connection with the device under test (DUT). It is compatible with the DUT's connection cable, establishing a reliable signal input channel between the DUT and the hub device, ensuring that various signals from the DUT can be smoothly transmitted into the device. The spherical protrusion 242 at the other end of the first electrical connector 24 allows for tight contact between the contact 242 and the conductive structure 32, reducing signal fluctuations caused by unstable contact area and minimizing wear during contact, thus extending the component's lifespan. Furthermore, the contact 242 can be made of materials with excellent conductivity, such as copper or aluminum. These materials effectively reduce resistance during signal transmission, minimizing signal loss and further ensuring the efficiency and accuracy of signal transmission between the DUT and external devices.

[0063] Optional, refer to Figure 3 and Figure 6 Each external fixing block 23 is provided with an external fixing block fixing foot 234 at one end facing the base 10, and an external fixing block fixing groove 100 is provided on the base 10, with each external fixing block fixing foot 234 placed in the corresponding external fixing block fixing groove 100.

[0064] In this embodiment of the invention, the outer fixing block fixing foot 234 provided at the end of each outer fixing block 23 facing the base 10 can be embedded in the corresponding outer fixing block fixing groove 100 on the base 10. This structural design provides a stable support for the outer fixing block 23, ensuring that it will not shift or shake during the operation of the hub device, thus guaranteeing the stability of the overall structure. At the same time, it also realizes a detachable connection between the outer fixing block 23 and the base 10. When it is necessary to replace a single outer fixing block 23, the disassembly operation can be easily completed by simply removing the outer fixing block fixing foot 234 from the outer fixing block fixing groove 100, thereby improving the flexibility of the hub device.

[0065] Optional, refer to Figure 2 A handle 33 is also provided on the other end of the rotating component 30; the handle 33 has an indicator hole 330, the position of which is aligned with the conduction structure 32 of the rotating component 30; the conduction structure 32 includes a fifth through hole 320 and a second electrical connector 321 disposed in the fifth through hole 320; the fifth through hole 320 penetrates the rotating component 30 along the radial direction X, and multiple fifth through holes 320 are arranged at intervals along the axial direction Y of the rotating component 30; each fifth through hole 320 is provided with a corresponding second electrical connector 321.

[0066] In this embodiment of the invention, the handle 33 provided at the other end of the rotating member 30 makes the rotation operation more effortless. The indicator hole 330 on the handle 33 can intuitively indicate the access port 22 corresponding to the current conductive structure 32, allowing the operator to clearly understand the target device under test that is currently connected. For example, when the indicator hole 330 is aligned with the first target access port a1 connected to the connection cable of the first computer host under test, it means that the first computer host under test is connected to the external device, and the external device function test of the first computer host under test can be performed; when the external device function test of the second computer host under test needs to be performed, the handle 33 is rotated to align the indicator hole 330 with the second target access port a2 connected to the connection cable of the second computer host under test.

[0067] The fifth through hole 320, which penetrates radially X along the rotating component 30, provides installation space for the second electrical connector 321. The arrangement of multiple fifth through holes 320 at intervals along the axial Y of the rotating component 30 matches the arrangement of the third through holes 230 on the first connecting assembly 20, enabling each second electrical connector 321 to precisely mate with its corresponding first electrical connector 24. This reliably establishes signal conduction between the target device under test and the external device, ensuring the stability and accuracy of signal transmission during testing.

[0068] Optional, refer to Figure 7 and Figure 8Each second electrical connector 321 includes: a conductive sleeve 3210, an electrical connecting post 3211, and a second spring (not shown in the figure); each second spring is sleeved on the corresponding electrical connecting post 3211, and each second spring is coaxial with the corresponding electrical connecting post 3211; each conductive sleeve 3210 is sleeved on one end of the corresponding electrical connecting post 3211, and the other end of each electrical connecting post 3211 is a spherical protrusion contact 242, and each conductive sleeve 3210 is coaxial with the corresponding electrical connecting post 3211; the rotating member 30 is provided with a sixth through hole 34, which penetrates the rotating member 30 along the axial direction Y of the rotating member 30, and a plurality of second electrical connectors 321 are placed in the sixth through hole 34.

[0069] In this embodiment of the invention, a conductive sleeve 3210 is fitted onto one end of the electrical connection post 3211, and the two are coaxially arranged, which can provide stable support and protection for the electrical connection post 3211, and also help to enhance the stability of signal transmission. The other end of the electrical connection post 3211 adopts a spherical protrusion contact 242 design. This structure can achieve good point contact during contact, reduce loss during signal transmission, and reduce contact wear during the rotation switching of the rotating part 30, thus extending the service life of the component.

[0070] The second spring, sleeved on and coaxial with the electrical connecting post 3211, possesses excellent elastic restoring capability. When the rotating component 30 rotates to align the second electrical connecting post 321 with the first electrical connecting post 24, the second spring is compressed, generating a reverse thrust that pushes the electrical connecting post 3211 towards the first electrical connecting post 24, ensuring tight contact between the two contacts and preventing poor contact due to gaps. Furthermore, multiple second electrical connecting posts 321 are housed within the sixth through hole 34 extending axially Y-axis through the rotating component 30, making installation relatively convenient and the structure more compact.

[0071] Optional, refer to Figure 9 , Figure 10 and Figure 11 The second connecting component 40 includes: a columnar inner fixing block 41 with a seventh through hole 410 extending through the Y axis and a plurality of coils 42; each coil 42 is arranged circumferentially around the inner fixing block 41, and the plurality of coils 42 are spaced apart along the axial Y axis of the second connecting component 40; the inner fixing block 41 is provided with a plurality of grooves 411 in the circumferential direction, and each coil 42 is disposed in a corresponding groove 411; each coil 42 is provided with a second wiring port 420, which is used to connect to the connection line of an external device.

[0072] In this embodiment of the invention, the columnar inner fixing block 41 has a seventh through hole 410 extending along the axial direction Y, providing space for the internal wiring arrangement. Multiple grooves 411 arranged circumferentially on the inner fixing block 41 provide mounting positions for the coils 42, with each coil 42 correspondingly positioned in one groove 411, preventing displacement of the coils 42 during use and ensuring the stability of the coil installation.

[0073] In this embodiment of the invention, there are 10 coils 42, which can support connection to the connection lines of up to 10 kinds of external devices. The multiple coils 42 are arranged at intervals along the axial Y of the second connecting component 40, so that each coil 42 can correspond to different signal transmission requirements. The second terminal 420 on each coil 42 is used to connect to the connection line of the external device, realizing the signal transmission between the external device and the conductive structure 32, thereby completing the connection between the external device and the target device under test, and providing a reliable path for signal transmission during the testing process.

[0074] Optional, refer to Figure 6 and Figure 9 The inner fixing block 41 is provided with an inner fixing block fixing foot 412 at one end facing the base 10, and the base 10 is provided with an inner fixing block fixing groove 101, with each inner fixing block fixing foot 412 placed in the corresponding inner fixing block fixing groove 101.

[0075] In this embodiment of the invention, the inner fixing block fixing foot 412 provided at the end of the inner fixing block 41 facing the base 10 can be embedded in the corresponding inner fixing block fixing groove 101 on the base 10. This structural design provides a stable support for the inner fixing block 41, ensuring that it will not be displaced or shaken during the operation of the hub device, thus ensuring the stability of the overall structure. At the same time, it also realizes the detachable connection between the inner fixing block 41 and the base 10, improving the flexibility of the hub device.

[0076] Optional, refer to Figure 12 The base 10 is provided with a seventh through hole 102, which penetrates the base 10 along the axial direction Y. The lower part of the base 10 is provided with a wire groove 103, which is connected to the seventh through hole 102.

[0077] In this embodiment of the invention, the seventh through hole 102 extending along the Y-axis on the base 10 provides a convenient channel for the internal wiring of the device. The connection wires of external devices can pass through the seventh through hole 102 through the base 10, avoiding the messy tangling of wires outside the device, making the overall wiring more neat and orderly, which not only improves the aesthetics of the device, but also reduces the risk of damage to the wires due to external pulling.

[0078] The wire groove 103 provided at the lower part of the base 10 is connected to the seventh through hole 102. The wires passing through the seventh through hole 102 can be smoothly introduced into the wire groove 103. The wire groove 103 can fix and protect the wires, prevent the wires from moving randomly and causing poor contact, and also facilitate the operator to sort and maintain the line, providing strong support for the stable operation of the device and ensuring that the signal transmission process is not affected by the line layout problem.

[0079] In summary, this hub device, through the 360° rotation of its rotating component, allows the conductive structure to interface with multiple access ports, enabling rapid switching of the same external device between multiple computer hosts under test. Compared to the traditional method of repeatedly plugging and unplugging signal cables, device switching can be completed with a simple rotation operation, significantly shortening the test interval and improving the efficiency of batch testing. It is particularly suitable for functional testing scenarios of external devices on large-scale computer hosts. Furthermore, this hub device can expand the number of access ports by increasing the number of external fixing blocks, accommodating the testing needs of more devices under test.
