Description

Technical Field

[0001] This utility model relates to the field of cable branch box technology, specifically a copper busbar installation structure for a cable branch box. Background Technology

[0002] Cable distribution boxes are important devices in power systems used for distributing and managing power cable connections. They are mainly used for cable branching, splicing, and termination, ensuring safe and reliable power transmission while facilitating cable maintenance and repair. Cable distribution boxes can be installed underground, on walls, or on utility poles, depending on the application scenario. They are widely used in urban power grid construction, industrial park power supply, and residential area power distribution, playing a vital role in improving the stability and security of power supply.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN219067790U) discloses a copper busbar installation structure for a cable branch box, comprising a box body, copper busbars disposed within the box body, and insulating screws; the copper busbars have mutually perpendicular long side mounting surfaces and long side surfaces, and the insulating screws pass through all the copper busbars, with both ends of the insulating screws connected to the two side walls of the box body respectively; positioning nuts are threaded onto the insulating screws, and the positioning nuts are distributed on both sides of the copper busbars to fix the relative position between the copper busbars and the insulating screws; the copper busbars are arranged at intervals on the insulating screws, and one long side surface of the copper busbars faces the opening side of the box body.

[0004] While the aforementioned patent improves work efficiency by allowing for more convenient tightening of cable bolts through flexible adjustment of the distance between copper busbars during cable installation, and facilitating observation of cable secureness, it still presents challenges. Installing copper busbars inside cable distribution boxes requires bolting one by one, with only a single busbar being worked on at a time. Technicians must repeat the same steps multiple times to complete the installation of all busbars. This inefficient method is time-consuming and labor-intensive. Furthermore, due to the lack of effective positioning devices, it is difficult to achieve accurate alignment between the copper busbars and pre-designed mounting holes on the first attempt. This forces installers to spend extra time and effort repeatedly correcting the position of the copper busbars to ensure proper alignment. This process not only increases the complexity and difficulty of the work but also increases the risk of human error, further affecting the final installation quality. In addition, the repeated adjustment of the copper busbar position can damage the material around the bolt holes, especially when applying significant force to correct the position. This can cause scratches on the copper busbar surface or deformation of the bolt hole edges, thus affecting the safety and reliability of the electrical connection.

[0005] Therefore, this utility model provides a copper busbar installation structure for a cable branch box to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a copper busbar installation structure for a cable branch box, such as... Figures 1-6 As shown, the technical solution includes a cable branch box body 1, an mounting plate 6 slidably connected to the inner cavity of the cable branch box body 1, a structural groove 22 is provided on one side of the inner wall of the cable branch box body 1 and one side of the mounting plate 6, a plurality of screw rods 11 are provided in the inner cavity of the structural groove 22, and two corresponding screw rods 11 are fixedly connected by a connecting rod 12, a sliding block 15 is threaded on the outer ring of the screw rod 11, an L-shaped abutment 14 is fixedly connected to one side of the outer surface of the sliding block 15, a plurality of placement plates 10 are fixedly connected to one side of the inner wall of the cable branch box body 1 and one side of the mounting plate 6, a limit hole 16 is provided on the top of the placement plate 10, a plurality of copper busbar bodies 9 are provided in the inner cavity of the cable branch box body 1, and connection holes 24 are provided on both sides of the top of the copper busbar bodies 9.

[0029] A limiting groove 23 is provided on one side of the structural groove 22. Several moving blocks 13 are slidably connected to the inner cavity of the limiting groove 23. The outer surface of the sliding circular block 15 is fixedly connected to one side of the corresponding moving block 13.

[0030] The bottoms of the two lead screws 11 are rotatably connected to the bottom of the inner cavity of the corresponding structural groove 22 via a rotating shaft. The top of the cable branch box body 1 is fixedly installed with a first drive motor 3, and the top of the mounting plate 6 is fixedly installed with a second drive motor 4.

[0031] The top of a corresponding lead screw 11 passes through the top of the inner cavity of the corresponding structural groove 22 and is fixedly connected to the output shaft of the first drive motor 3. The top of a corresponding lead screw 11 passes through the top of the inner cavity of the adjacent structural groove 22 and is fixedly connected to the output shaft of the second drive motor 4.

[0032] Specifically: Personnel start the first drive motor 3 and the second drive motor 4 through the synchronous controller. The connecting rod 12 enables multiple lead screws 11 to rotate simultaneously, ensuring the consistency and synchronization of the operation and improving the installation efficiency. As the lead screws 11 rotate, multiple sliding blocks 15 begin to move downward. At the same time, the moving block 13 sliding in the inner cavity of the limiting groove 23 ensures the stability of the displacement of the sliding blocks 15. When the sliding blocks 15 move downward, they drive the L-shaped abutment 14 to move downward, thereby smoothly docking with the inner cavity of the connecting hole 24 and the limiting hole 16, and finally completing the fixation of multiple copper busbar bodies 9.

[0033] The L-shaped stop 14 is compatible with the limiting hole 16 and the connecting hole 24. A sealing plate 2 is hinged to one side of the cable branch box body 1.

A rotating rod 20 is rotatably connected to one side of the fixing plate 18 via a rotating shaft. One end of the rotating rod 20 extends through the inner wall of the adjacent cable branch box body 1 to one side of the cable branch box body 1. A drive motor 21 is fixedly installed on one side of the cable branch box body 1.

[0035] The output shaft of the drive motor 21 is fixedly connected to the extension end of the rotating rod 20. The outer ring of the rotating rod 20 is fitted with a gear 19, and the gear 19 is connected to the rack 17 by a snap-fit ​​connection.

[0036] Specifically: First, the operator places multiple copper busbar bodies 9 between two corresponding placement plates 10, so that the two ends of the copper busbar bodies 9 are located in the inner cavities of the two placement plates 10 respectively, and the bottom of the copper busbar bodies 9 is in contact with the inner cavity of the placement plate 10. The operator starts the drive motor 21, which drives the rotating rod 20 to rotate, thereby causing the gear 19 to rotate. The rotation of the gear 19 drives the rack 17 to move back and forth. The sliding plate 7 slides in the slide groove 8 to realize the movement of the mounting plate 6, so that the distance between the two sets of placement plates 10 can be flexibly adjusted within a certain range to ensure that the connecting hole 24 on the placement plate 10 and the limiting hole 16 can be accurately aligned, solving the problem of difficulty in aligning at one time during the installation process.
