Description

Technical Field

[0001] This utility model belongs to the technical field of cable intermediate fusion joints, and particularly relates to a cable intermediate fusion joint. Background Technology

[0002] Because power cables have limited manufacturing length, a complete power line can only be formed by connecting individual power cables to ensure the normal transmission of electricity. Furthermore, the insulation performance and core connection effect at the connection between cables should not be lower than that of the cable itself. The tool used to connect power cables is called a power cable joint. Cable fusion splicing technology is a "regeneration" of the cable structure, restoring the cable to a new state step by step. Cable joints made using this technology have more than 90% of the performance parameters of the cable itself, which can significantly reduce the frequency of line faults caused by cable joints.

[0003] A search revealed a fusion splice cable intermediate joint, such as the one disclosed in CN218385767U, which includes two sets of symmetrically distributed cable conductors and cable connectors. The cable connectors include a main board. The top and bottom of the front of the main board are provided with grooves extending along the length of the main board. The left and right ends of the front of the main board are provided with pipe clamp seats. The pipe clamp seats are provided with U-shaped clamps inside. The front of the main board has a rectangular groove facing inward. A bidirectional screw is connected inside the rectangular groove. The outer side of the bidirectional screw is threaded with screw slides. A hand crank is connected to one end of the bidirectional screw that passes through the outer side of the main board.

[0004] The above-described technical solution has certain beneficial effects, but the following problems exist in actual use:

[0005] 1. When the above-mentioned technical solution is used, the inside of the cable U-shaped clamp will cause some obstruction to the hand crank, making it inconvenient for the operator to operate quickly during the actual operation.

[0006] 2. The above-described technical solution cannot support the end of the cable during use, and it is prone to skewing during the actual welding process, which leads to welding deviation. Therefore, we propose a cable intermediate welding joint. Utility Model Content

[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a cable intermediate fusion joint according to this utility model.

[0029] like Figure 1-4 As shown, a cable intermediate fusion joint of this utility model includes a connecting mounting plate 1. A fixed through groove 2 is provided inside the connecting mounting plate 1. A bidirectional threaded rod 3 is movably connected to the inner side of the fixed through groove 2. A movable mounting block 4 is movably sleeved on the outer side of the surface of the bidirectional threaded rod 3. A connecting mounting block 5 is fixedly connected to the front surface of the movable mounting block 4. A driven bevel gear 6 is fixedly connected to one end of the bidirectional threaded rod 3. A connecting drive adjustment mechanism 7 is fixedly connected to one side of the connecting mounting plate 1. Fixed guide grooves 8 are symmetrically provided inside the connecting mounting plate 1. A movable clamping mechanism 9 is movably connected to the inner side of the fixed guide grooves 8.

[0030] A fixed base block 10 is fixedly connected to the middle of the front surface of the connecting mounting plate 1, and a fixed clamping mechanism 11 is fixedly connected to the top of the middle of the front surface of the connecting mounting plate 1.

[0031] The connecting drive adjustment mechanism 7 includes a connecting limiting frame 12. A movable sleeve 13 is movably inserted into the inner side of the connecting limiting frame 12. A movable rotating rod 14 is movably connected inside the movable sleeve 13. A driving bevel gear 16 is fixedly connected to the bottom end of the movable rotating rod 14. A fixed limiting collar 15 is fixedly sleeved on the outer surface of the movable rotating rod 14. A first rotating disk 17 is fixedly connected to the top of the movable rotating rod 14, which facilitates the insertion of the movable sleeve 13 into the inner side of the connecting limiting frame 12. The movable sleeve 13, movable rotating rod 14, fixed limiting collar 15, driving bevel gear 16 and first rotating disk 17 are installed, so that the driving bevel gear 16 and the driven bevel gear 6 are meshed and connected. Then, rotating the first rotating disk 17 drives the movable rotating rod 14, fixed limiting collar 15 and driving bevel gear 16 to rotate, which drives the driven bevel gear 6 and the bidirectional threaded rod 3 to rotate, thereby adjusting the position of the movable mounting block 4. The operation is convenient.

[0032] The movable clamping mechanism 9 includes a movable threaded rod 18, a fixed sleeve 19 fixedly sleeved on the outer surface of the movable threaded rod 18, a connecting limit plate 20 fixedly connected to one end of the movable threaded rod 18, a movable mounting block 22 movably sleeved on the outer surface of the movable threaded rod 18, a connecting clamping block 23 fixedly connected to the end of the movable mounting block 22, and a fastening nut 21 threadedly connected to the outer surface of the movable threaded rod 18, facilitating the rotation of the fastening nut 21 so that the fastening nut 21 and the outer surface of the connecting mounting plate 1 fit together. Under the action of the thread, the movable threaded rod 18 can move inside the fixed guide groove 8, driving the fixed sleeve 19, the connecting limit plate 20, the movable mounting block 22 and the connecting clamping block 23 to move, so that the connecting clamping block 23 can cooperate with the connecting mounting block 5 to clamp and fix the cable, which is convenient to operate.

[0033] The fixed clamping mechanism 11 includes a fixed connecting block 24. An adjusting threaded rod 25 is threadedly connected inside the fixed connecting block 24. A second rotating disk 26 is fixedly connected to the top of the adjusting threaded rod 25, and a connecting base 27 is fixedly connected to the bottom of the adjusting threaded rod 25. A limiting sleeve 28 is movably sleeved on the outer surface of the connecting base 27, and a connecting pressing block 29 is fixedly connected to the bottom of the limiting sleeve 28. This facilitates the rotation of the second rotating disk 26, which drives the adjusting threaded rod 25 and the connecting base 27 to rotate. This allows the adjusting threaded rod 25 to rotate inside the fixed connecting block 24 and move downwards. The connecting base 27 then drives the limiting sleeve 28 and the connecting pressing block 29 to move downwards, connecting and cooperating with the fixed base block 10 to clamp and fix the end of the cable, ensuring that the end of the cable is in a stable state and is easy to operate.

[0034] The outer side of the bottom surface of the connecting lower pressure block 29 fits against the inner side of the top of the fixed base block 10, so that the bottom end of the connecting lower pressure block 29 can be stably locked on the inner side of the top of the fixed base block 10, which can stably clamp and fix the end of the cable, making operation convenient.

[0035] The working principle of this cable intermediate fusion joint is as follows: During use, the movable sleeve 13 is inserted into the inner side of the connecting limiting frame 12. The movable sleeve 13, movable rotating rod 14, fixed limiting collar 15, driving bevel gear 16, and first rotating disk 17 are installed, so that the driving bevel gear 16 and driven bevel gear 6 are meshed together. Then, the first rotating disk 17 is rotated to drive the movable rotating rod 14, fixed limiting collar 15, and driving bevel gear 16 to rotate, which in turn drives the driven bevel gear 6 and bidirectional threaded rod 3 to rotate, thereby adjusting the position of the movable mounting block 4. At the same time, when the connecting mounting block 5 moves, it can drive the position of the movable clamping mechanism 9 to move. Then, the cable is inserted into the inner side of the movable clamping mechanism 9 and the connecting mounting block 5, so that the end of the cable is inside the top of the fixed bottom support block 10. Then, the fastening nut 21 is rotated to... The fastening nut 21 is in contact with the outer surface of the connecting mounting plate 1. Under the action of the thread, the movable threaded rod 18 can move inside the fixed guide groove 8, driving the fixed sleeve 19, the connecting limit plate 20, the movable mounting block 22 and the connecting clamping block 23 to move. This allows the connecting clamping block 23 to cooperate with the connecting mounting block 5 to clamp and fix the cable. At the same time, the second rotating disk 26 rotates, driving the adjusting threaded rod 25 and the connecting base 27 to rotate. This allows the adjusting threaded rod 25 to rotate inside the fixed connecting block 24 and move downward. This causes the connecting base 27 to drive the limit sleeve 28 and the connecting pressing block 29 to move downward and connect with the fixed base support block 10 to clamp and fix the end of the cable, so that the end of the cable is in a stable state. The overall structure is simple and the operation is convenient and quick.
