[0035] like Figures 1 to 7 As shown, the present invention provides a quick-connect device for cable termination of a ring network equipment, comprising an annular fixing member 1, a cable 2, and a terminal block 14. The cable 2 is located at the center of the annular fixing member 1 and is adapted to the terminal block 14. A plug-in assembly is provided between the terminal block 14 and the annular fixing member 1. The annular fixing member 1 has multiple mounting slots 9, each of which is rotatably connected to a rotating shaft 6. A pair of claws 7 are fixedly connected to the rotating shaft 6. An elastic adjustment assembly is provided between the rotating shaft 6 and the mounting slots 9. The end of the claws 7 away from the mounting slots 9 is in contact with the surface of the cable 2. The end of the annular fixing member 1 away from the terminal block 14 is threadedly connected to an annular clamping member 10. The annular clamping member 10 has multiple sets of clamping assemblies, which are adapted to the claws 7.

[0036] During operation, the operator first passes the clamping ring through one end of the cable 2, then passes the annular fixing piece 1 through the cable 2. The elastic adjustment component, in conjunction with the claw 7, clamps and fixes cables 2 of different diameters. Then, the clamping ring is threadedly connected to the annular fixing piece 1. The clamping component can further tighten the claw 7 to prevent the claw 7 from loosening and causing the annular fixing piece 1 to detach from the cable 2. After that, the operator inserts the cable 2 into the terminal block 14, and the plug-in component can quickly lock the annular fixing piece 1 and the terminal block 14 to prevent the cable 2 from detaching from the terminal block 14 during subsequent use.

[0037] The elastic adjustment assembly includes a mounting ring 3, a helical gear 4, a helical gear 5, and a torsion spring 8. The mounting ring 3 is rotatably connected to the annular fixing member 1. The helical gear 4 is fixedly connected to the mounting ring 3. The torsion spring 8 is fixedly connected between the two ends of the rotating shaft 6 and the inner wall of the mounting groove 9. The helical gear 5 is fixedly connected to the rotating shaft 6. The helical gear 5 is located between a pair of pawls 7 and is meshed with the helical gear 4.

[0038] During operation, before passing the annular fixing piece 1 through the cable 2, the operator first rotates the mounting ring 3, causing the helical gear 4 to rotate. This, in turn, causes the helical gear 5 to drive the pawl 7 on the rotating shaft 6 to rotate and open outwards. At the same time, the torsion spring 8 stores energy. Then, while keeping the pawl 7 open, the operator passes the annular fixing piece 1 through one end of the cable 2 and releases the mounting ring 3. The elastic potential energy stored in the torsion spring 8 can drive the pawl 7 to quickly reset and clamp the cable 2. The mounting ring 3 can be used to adjust multiple sets of pawl 7 simultaneously. Combined with the torsion spring 8, it is possible to quickly fix cables 2 of different diameters.

[0039] The clamping assembly includes a screw 11, a pressure plate 12, and a limiting rod 13. The annular clamping part 10 is provided with multiple screw holes and limiting holes. The screw 11 is internally threaded into the screw hole. The pressure plate 12 is rotatably connected to the inner end of the screw 11. The limiting rod 13 is fixedly connected to the pressure plate 12. The limiting rod 13 is slidably connected to the limiting hole.

[0040] During operation, after the clamping ring is threaded into the annular fixing part 1, the screw 11 is rotated to move the pressure plate 12 toward the claw 7 until it is in contact with and presses the claw 7. During this process, the pressure plate 12 will not rotate with the screw 11 due to the sliding engagement of the limiting rod 13 and the limiting hole. The screw 11 and the pressure plate 12 can press the claw 7, further strengthening the fixing effect between the annular fixing part 1 and the cable 2.

[0041] The plug-in assembly includes a mating ring 15 and a mounting ring 21. The mating ring 15 is fixedly connected to the terminal block 14. The mating ring 15 has an annular groove 16. An annular limiting member 19 is fixedly connected in the annular groove 16. The end of the annular fixing member 1 near the terminal block 14 is rotatably connected to the mounting ring 21. Multiple protrusions 22 are fixedly connected to the outer wall of the end of the mounting ring 21 away from the annular fixing member. An elastic limiting mechanism is provided in the protrusions 22. An elastic sliding mechanism is provided between the mounting ring 21 and the annular fixing member 1.

[0042] The elastic limiting mechanism includes a spring 23 and a limiting block 24. The limiting block 24 is slidably connected in the inner cavity of the protrusion 22. The spring 23 is fixed between the limiting block 24 and the inner cavity of the protrusion 22. The end of the limiting block 24 away from the spring 23 extends to the outside of the protrusion 22. The end of the limiting block 24 away from the spring 23 is provided with a slope.

[0043] The elastic sliding mechanism includes a support plate 25, a ring 26, a slider 28, and a second spring 29. Multiple support plates 25 are fixedly connected to the outer wall of the ring-shaped fixing member 1 near the terminal block 14. A ring 26 is fixedly connected between the multiple support plates 25. Multiple sliders 28 are slidably connected to the ring 26. The number of sliders 28 is the same as that of the support plates 25. A second spring 29 is fixedly connected between the slider 28 and the support plate 25. An L-shaped plate 27 is fixedly connected between the slider 28 and the mounting ring 21.

[0044] The annular limiting member 19 is provided with multiple through grooves 20, and the docking ring 15 is provided with multiple guide grooves 17 and guide grooves 18. Guide grooves 17 and guide grooves 18 are connected to the annular groove 16, and the through grooves 20 are adapted to the guide grooves 18.

[0045] During operation, before inserting cable 2 into connector 14, align limit block 24 with guide groove 17 and slide mounting ring 21, allowing limit block 24 to slide along guide groove 17 into annular groove 16. Upon passing annular limit member 19, limit block 24 is pressed against the inner cavity of protrusion 22 and slides, compressing spring 23. After limit block 24 slides away from annular limit member 19, under the elastic force of spring 23, limit block 24 pops out of protrusion 22 and resets. At this point, cable 2 and connector 14 are connected. Through the cooperation between limit block 24 and annular limit member 19, mounting ring 21 and mating ring 15 are locked together. This prevents cable 2 from detaching from the connector 14 during subsequent use. When cable 2 needs to be removed for maintenance, first rotate the second mounting ring 21, so that the slider 28 slides on the ring 26 while compressing the second spring 29, until the limit block 24 rotates to correspond with the through groove 20 and the guide groove 18. Then, the operator slides the second mounting ring 21 outward, so that the limit block 24 slides out along the through groove 20 and the guide groove 18, thereby causing the second mounting ring 21 to detach from the docking ring 15. At the same time, cable 2 leaves the connector 14. Afterward, under the elastic force of the second spring 29, the slider 28 drives the second mounting ring 21 to rotate and reset quickly, so that it can continue to be locked with the docking ring 15 after maintenance.

[0046] A rubber pad is fixed to one end of the claw 7 near the cable 2;

[0047] During operation, the rubber pads on the claw 7 can increase the friction between the claw 7 and the surface of the cable 2, thereby enhancing the clamping effect.

[0048] Working principle: First, the operator passes the clamping ring through one end of cable 2, then rotates the mounting ring 3, causing the helical gear 4 to rotate. This, in turn, causes the helical gear 5 to drive the pawl 7 on the rotating shaft 6 to rotate and open outwards. Simultaneously, the torsion spring 8 stores energy. Then, while keeping the pawl 7 open, the operator passes the annular fixing piece 1 through one end of cable 2, and then releases the mounting ring 3. The elastic potential energy stored in the torsion spring 8 causes the pawl 7 to quickly return to its original position, clamping and fixing cable 2. Then, the clamping ring and... After the annular fastener 1 is threaded, rotating the screw 11 causes the pressure plate 12 to move towards the claw 7 until it is in contact with and presses against the claw 7. Before inserting the cable 2 into the connector 14, the limiting block 24 is aligned with the guide groove 17, and the second mounting ring 21 is slidably installed, so that the limiting block 24 slides along the guide groove 17 into the annular groove 16. When passing the annular limiting member 19, the limiting block 24 is pressed by the annular limiting member 19 into the inner cavity of the protrusion 22 and slides, compressing the spring 23. After the limiting block 24 slides away from the annular limiting member 19, under the elastic force of the spring 23, the limiting block 24 pops out of the inner cavity of the protrusion 22 and resets. At this time, the cable 2 and the terminal block 14 are connected. Through the cooperation between the limiting block 24 and the annular limiting member 19, the mounting ring 21 and the docking ring 15 are locked, preventing the cable 2 from coming off the terminal block 14 during subsequent use. When it is necessary to remove the cable 2 for maintenance, first rotate the mounting ring 21 so that the slider 28 slides on the ring 26. While moving, the second spring 29 is compressed until the limit block 24 rotates to correspond with the through groove 20 and the second guide groove 18. The operator slides the second installation ring 21 outward, so that the limit block 24 slides out along the through groove 20 and the second guide groove 18, thereby causing the second installation ring 21 to disengage from the docking ring 15. At the same time, the cable 2 leaves the terminal block 14. Then, under the elastic force of the second spring 29, the slider 28 drives the second installation ring 21 to rotate and reset quickly, which makes it easy for the operator to quickly install and remove the second installation ring 21.

[0049] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
