[0003] A hub is a network device used to connect multiple computers or other network devices to achieve data transmission and resource sharing. It simplifies network cabling and management by providing a central node that allows multiple devices to be connected to a single network. A hub usually has multiple ports, and each port can be connected to an electrical connector to support communication between different devices.

[0004] In the existing hubs during use, after being connected to multiple electrical connectors, multiple data lines are often prone to being entangled with each other. Such entanglement not only makes line management complicated but also may cause damage to the data lines due to pulling or pressing, affecting the stability of data transmission. When maintenance of the hub or the connected devices is required, the entangled data lines increase the difficulty and time cost of repair. Therefore, this application provides a hub and its electrical connector. Summary of the Invention

[0005] The purpose of this application is to solve the problem that multiple data lines are prone to being entangled with each other after connection, which not only makes line management complicated but also may cause damage to the data lines due to pulling or pressing. This application provides a hub and its electrical connector.

[0006] To achieve the above purpose, this application specifically adopts the following technical solutions:

[0007] A hub includes a hub body. A plurality of jacks are provided on one side of the hub body. A U-shaped block is slidably connected inside the hub body. A telescopic component is installed inside the hub body. A through groove is provided inside the U-shaped block. A plurality of arc-shaped clamping plates I are evenly and fixedly connected to the top surface of the through groove. A plurality of wire arranging mechanisms are evenly installed inside the through groove. Heat dissipation holes are symmetrically provided on both sides of the hub body. Dust-proof nets are fixedly connected to the interiors of the two heat dissipation holes. Heat dissipation components are installed inside the two heat dissipation holes.

[0008] By adopting the above technical solution, a plurality of data lines are passed through the inside of the through groove, and each plug is placed inside the corresponding arc-shaped clamping plate one. At this time, by controlling a plurality of wire arranging mechanisms, each plug can be clamped and fixed, so that each plug is separated from each other, so as to realize the combing function between multiple plugs, and avoid the entanglement of multiple plugs during long-term use. In addition, during daily use, the hub body will continuously emit heat, and these heats will be dissipated to the outside through the heat dissipation holes, so as to maintain the normal operation of the hub body. At the same time, the dust-proof net can effectively prevent dust from entering the heat dissipation holes. When the temperature inside the hub body is relatively high, the heat dissipation component can be automatically started to operate, so as to greatly improve the heat dissipation effect inside the hub body. At the same time, when the heat dissipation component is operating, the outer wall of the dust-proof net will also be cleaned together.

[0009] Further, the telescopic component includes a lead screw rotatably connected through the inside of the hub body. One end of the lead screw is fixedly connected with a knob. A guide rod is fixedly connected inside the hub body. One end of the U-shaped block is threadedly connected to the lead screw, and the other end of the U-shaped block is slidably connected to the guide rod.

[0010] By adopting the above technical solution, manually rotate the knob to drive the lead screw to rotate. At this time, under the guidance of the guide rod, the U-shaped block will be pushed to move on the lead screw, so as to extend the U-shaped block out of the hub body.

[0011] Further, the wire arranging mechanism includes a plurality of fixed blocks fixedly connected inside the through groove. A moving plate is slidably connected inside each of the plurality of fixed blocks. A connecting plate is fixedly connected to the top of the moving plate. The connecting plate is slidably connected through the fixed block. An arc-shaped clamping plate two is fixedly connected to the top of the connecting plate. Protective pads are fixedly connected to the arc-shaped surfaces of the arc-shaped clamping plate one and the arc-shaped clamping plate two. A handle is fixedly connected to one side of the moving plate. A chute is opened on one side of the fixed block. The handle is slidably connected inside the chute. Two springs are symmetrically and fixedly connected inside the moving plate. One end of the spring two is fixedly connected to the bottom of the moving plate. Locking components are arranged on both sides of the top of the moving plate.

[0012] By adopting the above technical solution, through the mutual cooperation of the arc-shaped clamping plate one and the arc-shaped clamping plate two, each plug is clamped and fixed, and at the same time, the device can also be adapted to plugs of different models, so as to realize the combing function between multiple plugs, and avoid the entanglement of multiple plugs during long-term use, thereby making the line management simple and convenient.

[0013] Further, the locking component includes connecting blocks symmetrically and fixedly connected to the top of the moving plate. Grooves are formed on one side of each of the two connecting blocks. A first spring is fixedly connected inside the groove. A clamping block is slidably connected inside the groove. One end of the first spring is fixedly connected to one end of the clamping block. The end of the clamping block away from the first spring is arc-shaped. A plurality of card slots are evenly formed on both sides inside the fixed block. The shape and size of the card slot are the same as the arc-shaped end of the clamping block.

[0014] By adopting the above technical solution, through the clamping cooperation between the clamping block and the card slot, the position of the moving plate can be fixed and limited, preventing the clamping from loosening during daily use and causing multiple plugs to be entangled.

[0015] Further, the heat dissipation component includes a cooling fan fixedly connected inside the heat dissipation holes. A connecting shaft is rotatably connected through the center of the dust-proof net. One end of the connecting shaft is fixedly connected to the axis center of the cooling fan. A cleaning component is arranged at the other end of the connecting shaft.

[0016] By adopting the above technical solution, when the temperature inside the hub body is relatively high, the cooling fan can be automatically started to operate. Through the rotation of the cooling fan, the heat dissipation effect inside the hub body can be greatly improved.

[0017] Further, the cleaning component includes a support block fixedly connected to one end of the connecting shaft. Guide grooves are symmetrically formed on one side of the support block. A third spring is fixedly connected inside each of the two guide grooves. A moving block is fixedly connected inside each of the two guide grooves. One end of the third spring is fixedly connected to one end of the moving block. A cleaning plate is fixedly connected to the sides of the two moving blocks away from the third spring. One side of the cleaning plate is attached to one side of the dust-proof net.

[0018] By adopting the above technical solution, the guide of the moving block will make one side of the cleaning plate closely attached to one side of the dust-proof net. Through the continuously rotating cleaning plate, the outer wall of the dust-proof net can be effectively cleaned, thereby cleaning the dust adhering to the outer wall of the dust-proof net.

[0019] Further, a first circular convex block is symmetrically and fixedly connected to one side of one of the moving blocks. A plurality of second circular convex blocks are spaced and fixedly connected to one side of the dust-proof net.

[0020] By adopting the above technical solution, during the continuous rotation of the support block driving the moving block, the two first circular convex blocks on one side of the moving block will intermittently collide with the second circular convex blocks, so that the moving block can drive the cleaning plate to intermittently impact the outer wall of the dust-proof net.

[0021] An electrical connector includes an electrical connector head. One end of the electrical connector head is fixedly connected with a connecting wire, and the other end of the electrical connector head is fixedly connected with a plug, and the plug can be inserted into a jack.

[0036] The following further describes this application in detail with reference to Figure 1 —7.

[0037] The embodiment of this application discloses a hub and its electrical connector.

[0038] Referring to Figure 1 , Figure 2 and Figure 3 , a hub and its electrical connector include a hub body 1. A plurality of jacks 5 are opened on one side of the hub body 1. A U-shaped block 6 is slidably connected inside the hub body 1. A telescopic component is installed inside the hub body 1. A through groove 7 is opened inside the U-shaped block 6. A plurality of first arc-shaped clamping plates 8 are evenly and fixedly connected to the top surface of the through groove 7. A plurality of whole-line mechanisms are evenly installed inside the through groove 7. Heat dissipation holes 25 are symmetrically opened on both sides of the hub body 1. Dust-proof nets 26 are fixedly connected inside both heat dissipation holes 25. Heat dissipation components are installed inside both heat dissipation holes 25. The telescopic component includes a lead screw 9 that is rotatably connected through the inside of the hub body 1. One end of the lead screw 9 is fixedly connected to a knob 10. A guide rod 11 is fixedly connected inside the hub body 1. One end of the U-shaped block 6 is threadedly connected to the lead screw 9, and the other end of the U-shaped block 6 is slidably connected to the guide rod 11;

[0039] Secondly, it includes an electrical connector head 2. One end of the electrical connector head 2 is fixedly connected with a connecting wire 3, and the other end of the electrical connector head 2 is fixedly connected with a plug 4. The plug 4 can be inserted into the jack 5.

[0040] When in use, first take out multiple electrical connector heads 2, and then align the connecting wires 3 with the corresponding jacks 5 and insert them to achieve the connection between the hub body 1 and the electrical connector heads 2. After multiple electrical connector heads 2 are connected, the knob 10 can be manually rotated first to drive the screw rod 9 to rotate. At this time, guided by the guide rod 11, the U-shaped block 6 will be pushed to move on the screw rod 9, so as to extend the U-shaped block 6 out of the hub body 1. Then, pass multiple plugs 4 through the inside of the through groove 7, and place each plug 4 inside the corresponding arc-shaped clamping plate 1 8. At this time, by operating multiple wire arranging mechanisms, each plug 4 can be clamped and fixed, so that each plug 4 is separated from each other to achieve the sorting function between multiple plugs 4, avoiding multiple plugs 4 being wound together during long-term use, making the line management simple and convenient. At the same time, the wire arranging mechanism can also keep the plugs 4 stable, reducing the damage of the plugs 4 caused by pulling or pressing and the connection between the connecting wires 3 and the jacks 5, effectively maintaining the stability of data transmission. At the same time, when the hub body 1 or the electrical connector head 2 needs to be maintained later, the difficulty and time cost of maintenance can also be reduced;

[0041] In addition, during daily use, the hub body 1 continuously emits heat, and this heat will be dissipated to the outside through the heat dissipation holes 25 to keep the normal use and operation of the hub body 1. At the same time, the dust-proof net 26 can effectively prevent dust from entering the inside of the hub body 1 through the heat dissipation holes 25 and affecting the operation of the equipment. When the temperature inside the hub body 1 is relatively high, the heat dissipation component can be automatically started to operate to greatly improve the heat dissipation effect inside the hub body 1. At the same time, when the heat dissipation component is operating, the outer wall of the dust-proof net 26 will also be cleaned to clean the dust adhered to the outer wall of the dust-proof net 26, so as to prevent the dust from accumulating and causing the dust-proof net 26 to be blocked, affecting the heat dissipation efficiency of the hub body 1.

[0042] Refer to Figure 1 、 Figure 4 and Figure 5, the whole wire mechanism includes a plurality of fixed blocks 12 fixedly connected inside the through groove 7. A moving plate 13 is slidably connected inside each of the plurality of fixed blocks 12. A connecting plate 14 is fixedly connected to the top of the moving plate 13. The connecting plate 14 is slidably connected through the fixed block 12. An arc-shaped clamping plate two 15 is fixedly connected to the top of the connecting plate 14. Protective pads 16 are fixedly connected to the arc-shaped surfaces of the arc-shaped clamping plate one 8 and the arc-shaped clamping plate two 15. A handle 17 is fixedly connected to one side of the moving plate 13. A sliding groove 18 is opened on one side of the fixed block 12. The handle 17 is slidably connected inside the sliding groove 18. Two springs two 24 are symmetrically and fixedly connected inside the moving plate 13. One end of each spring two 24 is fixedly connected to the bottom of the moving plate 13. Locking components are arranged on both sides of the top of the moving plate 13.

[0043] When in use, first manually pull the handle 17 to drive the moving plate 13 to slide upward inside the fixed block 12 under the guidance of the sliding groove 18. At this time, due to the movement of the moving plate 13, the connecting plate 14 on the top will be pushed to drive the arc-shaped clamping plate two 15 to approach the arc-shaped clamping plate one 8, so as to clamp and fix each plug 4 through the mutual cooperation of the arc-shaped clamping plate one 8 and the arc-shaped clamping plate two 15. At the same time, it can also make the device adapt to plugs 4 of different models. And through the fit between the protective pad 16 and the plug 4, the plug 4 can be effectively buffered and protected, reducing the damage to the plug 4. By clamping each plug 4 separately, the sorting function between multiple plugs 4 is realized, avoiding the entanglement of multiple plugs 4 during long-term use, making the line management simple and convenient. At the same time, through the whole wire mechanism, the stability of the plug 4 can also be maintained, reducing the damage to the plug 4 and the connection between the connecting wire 3 and the jack 5 caused by pulling or pressing, effectively maintaining the stability of data transmission. At the same time, when the hub body 1 or the electrical connector head 2 needs to be maintained in the later stage, the difficulty and time cost of maintenance can also be reduced.

[0044] Refer to Figure 1 , Figure 4 and Figure 5 , the locking component includes connecting blocks 19 symmetrically and fixedly connected to the top of the moving plate 13. Grooves 20 are opened on one side of each of the two connecting blocks 19. A spring one 21 is fixedly connected inside the groove 20. A clamping block 22 is slidably connected inside the groove 20. One end of the spring one 21 is fixedly connected to one end of the clamping block 22. The end of the clamping block 22 away from the spring one 21 is arc-shaped. A plurality of card slots 23 are evenly opened on both sides inside the fixed block 12. The shape and size of the card slots 23 are the same as those of the arc-shaped end of the clamping block 22.

[0045] During use, while the moving plate 13 is moving, it will also drive the two connecting blocks 19 to move together. At this time, the inner wall of the fixed block 12 will squeeze the clamping block 22 into the inside of the groove 20. As the moving plate 13 gradually moves, after the arc-shaped clamping plate one 8 and the arc-shaped clamping plate two 15 tightly fit and clamp the plug 4, at this time, the groove 20 will be on the same horizontal line as one of the clamping grooves 23. Therefore, through the rebound of the first spring 21, it will push the clamping block 22 into the inside of the clamping groove 23. In this way, through the clamping cooperation between the clamping block 22 and the clamping groove 23, the position of the moving plate 13 can be fixed and limited, preventing the situation that multiple plugs 4 are wound due to loose clamping during daily use.

[0046] Referring to Figure 1 , Figure 6 and Figure 7 , the heat dissipation component includes a heat dissipation fan 27 fixedly connected inside the heat dissipation hole 25. A connecting shaft 28 is rotatably connected through the center of the dust-proof net 26. One end of the connecting shaft 28 is fixedly connected to the axis center of the heat dissipation fan 27, and a cleaning component is arranged at the other end of the connecting shaft 28;

[0047] Secondly, the cleaning component includes a support block 29 fixedly connected to one end of the connecting shaft 28. Guide grooves 30 are symmetrically opened on one side of the support block 29. Spring three 31 is fixedly connected inside each of the two guide grooves 30. A moving block 32 is fixedly connected inside each of the two guide grooves 30. One end of the spring three 31 is fixedly connected to one end of the moving block 32. A cleaning plate 33 is fixedly connected to the sides of the two moving blocks 32 away from the spring three 31. One side of the cleaning plate 33 is in contact with one side of the dust-proof net 26. Circular convex block one 34 is symmetrically fixedly connected to one side of one of the moving blocks 32. A plurality of circular convex blocks two 35 are fixedly connected to one side of the dust-proof net 26 at intervals.

[0048] During use, when the temperature inside the hub body 1 is relatively high, the cooling fan 27 can be automatically started to operate. By the rotation of the cooling fan 27, the heat dissipation effect inside the hub body 1 can be significantly improved. Additionally, while the cooling fan 27 is operating, the support block 29 will be driven to rotate continuously through the connecting shaft 28. During the rotation of the support block 29, due to the elasticity of the third spring 31, two moving blocks 32 will always be pushed outward. Thus, through the guidance of the moving blocks 32, one side of the cleaning plate 33 will be closely attached to one side of the dust-proof net 26. The outer wall of the dust-proof net 26 can be effectively cleaned by the continuously rotating cleaning plate 33, thereby cleaning the dust adhering to the outer wall of the dust-proof net 26 to prevent dust accumulation from causing blockage of the dust-proof net 26 and affecting the heat dissipation efficiency of the hub body 1. Moreover, during the process of the support block 29 driving the moving blocks 32 to rotate continuously, the two circular protrusions one 34 on one side of the moving block 32 will intermittently collide with the circular protrusion two 35. Since both the circular protrusion one 34 and the circular protrusion two 35 are circular, through the collision and extrusion with the circular protrusion two 35, the moving block 32 will be pushed to slightly move inside the guiding groove 30. When the circular protrusion one 34 continues to rotate and separates from the circular protrusion two 35, according to the rebound of the third spring 31, the moving block 32 will be driven to reset again. In this way, the moving block 32 can drive the cleaning plate 33 to intermittently impact the outer wall of the dust-proof net 26, enabling some dust that is not easily cleaned on the surface of the dust-proof net 26 to be separated from the dust-proof net 26 through impact and vibration, greatly improving the cleanliness of the dust-proof net 26 and reducing the blockage situation.

[0049] The implementation principle of a hub and its electrical connectors in this embodiment is as follows: When in use, first take out multiple electrical connector heads 2, and then align the connecting wire 3 with the corresponding jacks 5 and insert it to achieve the connection between the hub body 1 and the electrical connector heads 2. After multiple electrical connector heads 2 are connected, the knob 10 can be manually rotated first to drive the lead screw 9 to rotate. At this time, guided by the guide rod 11, the U-shaped block 6 will be pushed to move on the lead screw 9, so as to extend the U-shaped block 6 from the inside of the hub body 1. Then, multiple plugs 4 are passed through the inside of the through groove 7, and each plug 4 is placed inside the corresponding arc-shaped clamping plate one 8. At this time, by manually pulling the handle 17 and driving the moving plate 13 to slide upward inside the fixed block 12 according to the guide of the chute 18. At this time, through the movement of the moving plate 13, the top connecting plate 14 will be pushed to drive the arc-shaped clamping plate two 15 to approach the arc-shaped clamping plate one 8, so as to clamp and fix each plug 4 through the mutual cooperation of the arc-shaped clamping plate one 8 and the arc-shaped clamping plate two 15. At the same time, the device can also be adapted to different models of plugs 4. And through the fitting between the protective pad 16 and the plug 4, the plug 4 can be effectively buffered and protected, reducing the damage to the plug 4. By individually clamping each plug 4, the sorting function between multiple plugs 4 is realized, avoiding the entanglement of multiple plugs 4 during long-term use, making the line management simple and convenient. At the same time, the wire organizing mechanism can also keep the plug 4 stable, reducing the damage to the plug 4 and the connection between the connecting wire 3 and the jack 5 caused by pulling or pressing, effectively maintaining the stability of data transmission. At the same time, when the hub body 1 or the electrical connector head 2 needs to be maintained later, the difficulty and time cost of maintenance can also be reduced;

[0050] Secondly, while the moving plate 13 is moving, it will also drive the two connecting blocks 19 to move together. At this time, the inner wall of the fixed block 12 will squeeze the block 22 into the inside of the groove 20. As the moving plate 13 gradually moves, after the arc-shaped clamping plate one 8 and the arc-shaped clamping plate two 15 tightly fit and clamp the plug 4, at this time, the groove 20 will be on the same horizontal line as one of the card slots 23. Therefore, through the rebound of the spring one 21, the block 22 will be pushed into the inside of the card slot 23. In this way, through the clamping cooperation between the block 22 and the card slot 23, the position of the moving plate 13 can be fixed and limited, preventing the situation of clamping looseness and multiple plugs 4 being entangled during daily use;

[0051] In addition, during daily use, the hub body 1 continuously emits heat, and this heat is dissipated to the outside through the heat dissipation holes 25 to maintain the normal use and operation of the hub body 1. At the same time, the dust-proof net 26 can effectively prevent dust from entering the inside of the hub body 1 through the heat dissipation holes 25 and reduce the influence of dust on the operation of the device. When the temperature inside the hub body 1 is relatively high, the cooling fan 27 can be automatically started to operate. By the rotation of the cooling fan 27, the heat dissipation effect inside the hub body 1 can be greatly improved. In addition, while the cooling fan 27 is operating, the support block 29 will be driven to rotate continuously through the connecting shaft 28. During the rotation of the support block 29, due to the elasticity of the third spring 31, it will always push the two moving blocks 32 outwards. Thus, through the guidance of the moving blocks 32, one side of the cleaning plate 33 will be closely attached to one side of the dust-proof net 26. The outer wall of the dust-proof net 26 can be effectively cleaned by the continuously rotating cleaning plate 33, so as to clean the dust adhered to the outer wall of the dust-proof net 26, preventing dust accumulation from causing blockage of the dust-proof net 26 and affecting the heat dissipation efficiency of the hub body 1. And during the continuous rotation of the support block 29 driving the moving blocks 32, the two circular protrusions one 34 on one side of the moving block 32 will intermittently collide with the circular protrusion two 35. Since both the circular protrusion one 34 and the circular protrusion two 35 are circular, through the collision and extrusion with the circular protrusion two 35, the moving block 32 will be pushed to move slightly inside the guiding groove 30. When the circular protrusion one 34 continues to rotate and separates from the circular protrusion two 35, according to the rebound of the third spring 31, the moving block 32 will be driven to reset again. In this way, the moving block 32 can drive the cleaning plate 33 to intermittently impact the outer wall of the dust-proof net 26, so that some dust that is not easily cleaned on the surface of the dust-proof net 26 can be separated from the dust-proof net 26 by impact and shaking, greatly improving the cleanliness of the dust-proof net 26 and reducing the blockage situation.
