[0038] When in use, first manually pull the handle 17 to drive the movable plate 13 to slide upward inside the fixed block 12 according to the guidance of the slide groove 18. At this time, through the movement of the movable plate 13, the top connecting plate 14 will be pushed to drive the arc clamping plate 2 15 to approach the arc clamping plate 1 8, so that each plug 4 can be clamped and fixed through the mutual cooperation of the arc clamping plate 1 8 and the arc clamping plate 2 15.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The locking assembly includes a connecting block 19 symmetrically fixedly connected to the top of the moving plate 13, and a groove 20 is provided on one side of the two connecting blocks 19. A spring 21 is fixedly connected inside the groove 20, and a block 22 is slidably connected inside the groove 20. One end of the spring 21 is fixedly connected to one end of the block 22, and the end of the block 22 away from the spring 21 is arc-shaped. A plurality of slots 23 are evenly provided on both sides of the interior of the fixed block 12, and the shape and size of the slots 23 are consistent with the arc-shaped end of the block 22.

[0040] When in use, while the movable plate 13 moves, the two connecting blocks 19 will also move together. At this time, the inner wall of the fixed block 12 will squeeze the card block 22 into the interior of the groove 20. As the movable plate 13 gradually moves, the arc-shaped clamping plate 1 8 and the arc-shaped clamping plate 2 15 will tightly fit and clamp the plug 4.

[0041] Reference Figure 1 , Figure 6 and Figure 7 The heat dissipation assembly includes a heat dissipation fan 27 fixedly connected to the inside of the heat dissipation hole 25, a connecting shaft 28 is rotatably connected to the center of the dustproof net 26, one end of the connecting shaft 28 is fixedly connected to the axis of the heat dissipation fan 27, and a cleaning assembly is provided at the other end of the connecting shaft 28; Secondly, the cleaning component includes a support block 29 fixedly connected to one end of the connecting shaft 28, and a guide groove 30 is symmetrically opened on one side of the support block 29, and a spring three 31 is fixedly connected inside the two guide grooves 30, and a moving block 32 is fixedly connected inside the two guide grooves 30, one end of the spring three 31 is fixedly connected to one end of the moving block 32, and a cleaning plate 33 is fixedly connected to the side of the two moving blocks 32 away from the spring three 31, and one side of the cleaning plate 33 is fitted with one side of the dustproof net 26, and a circular protrusion 1 34 is symmetrically fixedly connected to one side of the dustproof net 26, and a plurality of circular protrusions 2 35 are fixedly connected to one side of the dustproof net 26 at intervals.

[0042] During use, when the temperature inside the hub body 1 is high, the cooling fan 27 can be automatically started to operate. The rotation of the cooling fan 27 can greatly improve the heat dissipation effect inside the hub body 1. In addition, while the cooling fan 27 is running, the connecting shaft 28 will drive the support block 29 to rotate continuously. During the rotation of the support block 29, the elasticity of the spring three 31 will always push the two moving blocks 32 outward, so that one side of the cleaning plate 33 and one side of the dustproof net 26 are closely fitted through the guidance of the moving block 32. The outer wall of the dustproof net 26 can be effectively cleaned through the continuously rotating cleaning plate 33, so as to clean the dust adhering to the outer wall of the dustproof net 26, so as to prevent the dust from accumulating and clogging the dustproof net 26, which affects the heat dissipation efficiency of the hub body 1. When the support block 29 drives the moving block 32 to rotate continuously, the two circular protrusions 1 34 on one side of the moving block 32 will intermittently collide with the circular protrusion 2 35. Since the circular protrusions 1 34 and the circular protrusions 2 35 are both circular, the moving block 32 will be pushed to move slightly toward the inside of the guide groove 30 through the collision and extrusion with the circular protrusions 2 35. When the circular protrusions 1 34 continue to rotate and separate from the circular protrusions 2 35, the moving block 32 will be driven to reset again according to the rebound of the spring 31, so that the moving block 32 can drive the cleaning plate 33 to intermittently collide with the outer wall of the dustproof net 26, so that some dust adhering to the surface of the dustproof net 26 that is not easy to clean can be separated from the dustproof net 26 through the collision and shaking, which greatly improves the cleanliness of the dustproof net 26 and reduces blockage.

[0043] The implementation principle of a hub and its electrical connector in this embodiment is as follows: when in use, first take out a plurality of electrical connector heads 2, then align the connecting wires 3 with the corresponding jacks 5 and insert them, so as to achieve the connection between the hub body 1 and the electrical connector heads 2. After the plurality of electrical connector heads 2 are connected, the knob 10 can be manually turned to drive the screw rod 9 to rotate. At this time, the U-shaped block 6 is pushed to move on the screw rod 9 under the guidance of the guide rod 11, so as to extend the U-shaped block 6 from the inside of the hub body 1, and then a plurality of plugs 4 are passed through the inside of the through groove 7, and each plug 4 is placed in the corresponding arc-shaped clamping plate 1 8. At this time, the handle 17 is manually pulled to drive the movable plate 13 to slide upward inside the fixed block 12 according to the guidance of the slide groove 18. At this time, the movement of the movable plate 13 will push the top connecting plate 14 to drive the arc-shaped clamping plate 2 15 to the arc The arc-shaped clamping plate 1 8 is close to each other, so that each plug 4 can be clamped and fixed by the mutual cooperation of the arc-shaped clamping plate 1 8 and the arc-shaped clamping plate 2 15, and the device can also be adapted to plugs 4 of different models, and the fit between the protective pad 16 and the plug 4 can effectively buffer and protect the plug 4, reduce the damage to the plug 4, and realize the combing function between multiple plugs 4 by clamping each plug 4 separately, so as to avoid multiple plugs 4 being entangled together during long-term use, so as to make line management simple and convenient, and at the same time, the plug 4 can be kept stable through the line-straightening mechanism, reduce the damage of the plug 4 caused by pulling or pressing, and the connection between the connecting line 3 and the jack 5, effectively maintain the stability of data transmission, and at the same time, when the hub body 1 or the electrical connector head 2 needs to be maintained in the later stage, it can also reduce the difficulty and time cost of maintenance; Secondly, when the movable plate 13 moves, the two connecting blocks 19 are also driven to move together. At this time, the inner wall of the fixed block 12 will squeeze the card block 22 into the inside of the groove 20. As the movable plate 13 gradually moves, the arc-shaped clamping plate 1 8 and the arc-shaped clamping plate 2 15 are tightly fitted and clamped to the plug 4. At this time, the groove 20 is on the same horizontal line as one of the card slots 23. Therefore, the rebound of the spring 1 21 will push the card block 22 into the inside of the card slot 23. In this way, the position of the movable plate 13 can be fixed and limited by the card connection between the card block 22 and the card slot 23, so as to prevent the situation in which the clamping is loose and multiple plugs 4 are entangled during daily use. In addition, during daily use, the hub body 1 will continue to emit heat, which will be dissipated to the outside through the heat dissipation holes 25, so as to maintain the normal use and operation of the hub body 1. At the same time, the heat dissipation holes 25 can be effectively dustproofed through the dustproof net 26 to reduce the dust from entering 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 high, the cooling fan 27 can be started automatically. The rotation of the cooling fan 27 can greatly improve the heat dissipation effect inside the hub body 1. In addition, while the cooling fan 27 is running, the supporting block 29 will be driven to rotate continuously through the connecting shaft 28. During the rotation of the supporting block 29, the elasticity of the spring three 31 will always push the two moving blocks 32 outward, so that the one side of the cleaning plate 33 will fit closely with the one side of the dustproof net 26 through the guidance of the moving block 32, and the outer wall of the dustproof net 26 can be effectively cleaned by the continuously rotating cleaning plate 33. , in order to clean the dust adhering to the outer wall of the dustproof net 26, so as to prevent the dust accumulation from clogging the dustproof net 26 and affecting the heat dissipation efficiency of the hub body 1, and in the process of the support block 29 driving the moving block 32 to rotate continuously, the two circular protrusions 1 34 on one side of the moving block 32 will intermittently collide with the circular protrusions 2 35, and because the circular protrusions 1 34 and the circular protrusions 2 35 are both circular, the collision and extrusion with the circular protrusions 2 35 will push the moving block 32 to move slightly toward the inside of the guide groove 30, and when the circular protrusions 1 34 continue to rotate and separate from the circular protrusions 2 35, according to the rebound of the spring three 31, the moving block 32 will be driven to reset again, so that the moving block 32 can drive the cleaning plate 33 to intermittently collide with the outer wall of the dustproof net 26, so that some dust adhering to the surface of the dustproof net 26 that is not easy to clean can be separated from the dustproof net 26 by the collision and shaking, which greatly improves the cleanliness of the dustproof net 26 and reduces the blockage.
