Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a busbar with a cable routing device. Background Technology

[0002] Busbar trunking is a specialized device in a power system used for installing and fixing busbars. Located inside the trunking, it supports and arranges the busbars. Its design aims to ensure uniform distribution of busbars within the trunking and prevent displacement caused by vibration or thermal expansion. The design of the busbar arrangement device considers both electrical and mechanical performance requirements. Busbar trunking with this arrangement device is a crucial component for ensuring the safe and reliable operation of a power system.

[0003] The existing technology still has some problems: 1. When installing and fixing the busbar, the existing technology can only fix a busbar of a certain diameter and cannot fix busbars of different diameters. However, in actual wiring, in order to meet different wiring requirements, a variety of different models of busbars are required, which has poor adaptability and limited application scenarios.

[0004] 2. Existing busbar trunking is inconvenient to splice during wiring. However, in practical applications, it needs to adapt to different building structures and electrical layouts. With the expansion or renovation of the power system, the length of the busbar trunking may need to be increased or decreased, requiring a long splicing and connection time, resulting in low practicality.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a busbar trunking with a cable routing device.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0008] A busbar trunking system with a cable routing device includes:

[0009] A junction box, wherein the front and rear ends of the junction box are connected;

[0010] A cable routing device, comprising several symmetrically arranged arc-shaped plates, wherein the cable routing device completes cable routing by bringing the upper and lower arc-shaped plates close to each other;

[0011] A connecting device, comprising a connecting groove and a connecting rod that cooperate with each other, wherein the connecting device completes the connection of multiple junction boxes by confining the connecting rod within the connecting groove.

[0012] As an improvement, fixing plates are fixedly connected to the lower ends of both sides of the junction box.

[0013] As an improvement, the cable routing device further includes two mounting plates arranged vertically, both of which are located inside the junction box. The lower end of the lower mounting plate is fixedly connected to the lower end of the inner wall of the junction box. Several cable routing grooves are opened at the near ends of the upper and lower mounting plates. An arc-shaped plate is arranged between the upper and lower cable routing grooves. Several damping rods are fixedly connected between the far ends of the upper and lower arc-shaped plates and the inner walls of the upper and lower cable routing grooves. A spring is sleeved on the outer side of each damping rod. The two ends of the upper and lower springs are fixedly connected to the arc-shaped plate and the inner wall of the cable routing groove, respectively.

[0014] As an improvement, both sides of the upper mounting plate are fixedly connected to the middle of the upper end of the plate. A lead screw is threaded onto one of the protrusions, and a guide rod is slidably connected onto the other protrusion. The upper and lower ends of the lead screw are rotatably connected to the inner wall of the junction box, and the upper and lower ends of the guide rod are fixedly connected to the inner wall of the junction box.

[0015] As an improvement, a handwheel is rotatably connected to one side of the upper end of the wire box. The lower end of the handwheel extends through the wire box to the outside and is fixedly connected to the upper end of the lead screw. A bolt is threaded onto the handwheel. Several limiting holes are provided below the handwheel on the wire box. The bolt and the limiting holes are used in conjunction.

[0016] As an improvement, the connecting devices are arranged on both sides of the junction box, and the connecting devices on both sides are symmetrically arranged. The connecting rods are fixedly connected to the upper and lower parts of the front end of the junction box, and the connecting grooves are opened on both sides of the rear end of the junction box.

[0017] As an improvement, the connecting device further includes two connecting blocks, which are fixedly connected to the rear of both sides of the junction box. The near ends of the connecting blocks on both sides extend into the connecting groove. Each connecting block has a cavity inside. The upper and lower ends of the inner wall of the cavity are fixedly connected to a fixing rod. The upper and lower parts of the fixing rod are slidably connected to a pressing rod. The disjoint ends of the upper and lower pressing rods extend through the cavity to the outside.

[0018] As an improvement, a limiting block is fixedly connected to the front end of the pressing rod, and a second limiting hole is opened on each of the connecting rods. The limiting blocks at the upper and lower ends both extend through the cavity to the outside, and the limiting blocks and the second limiting hole are used in conjunction.

[0019] As an improvement, the upper and lower limit blocks are connected by a fixed damping rod two, and a spring two is sleeved on the outside of the damping rod two. The upper and lower ends of the spring two are fixedly connected to the upper and lower limit blocks respectively.

[0020] The advantages of this utility model compared with the prior art are as follows: 1. By rotating the handwheel to drive the lead screw to rotate, the upper mounting plate moves downward. After the upper and lower arc plates are in contact with the busbar, the handwheel is rotated again to compress the spring and damping rod, which buffers the clamping force to a certain extent. The handwheel is rotated again until the busbar is completely fixed. It has a strong adaptability and can complete the wiring of busbars of different diameters.

[0021] 2. First, place the two junction boxes side by side. Then, press the upper and lower pressing rods. The limiting blocks will move accordingly until they are fully inside the cavity. Next, push one of the junction boxes so that the connecting rod is inserted into the connecting groove. After the connecting rod has fully slid into the connecting groove, release the pressing rod and push the upper and lower limiting blocks into the upper and lower limiting holes. This completes the splicing connection. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Combined with appendix Figures 1-7 A busbar trunking system with a cable routing device mainly includes: a junction box 1, a cable routing device 2, and a connecting device 4. The junction box 1 is continuous from front to back, and a fixing plate 7 is fixedly connected to the lower ends of both sides of the junction box 1. The fixing plate 7 has several fixing holes for fixing the junction box 1. The cable routing device 2 includes several symmetrically arranged arc-shaped plates 3. The cable routing device 2 completes the cable routing by bringing the upper and lower arc-shaped plates 3 closer together.

[0032] Specifically, the wiring device 2 also includes two mounting plates 8 arranged vertically. The mounting plates 8 are both located inside the junction box 1. The lower end of the lower mounting plate 8 is fixedly connected to the lower end of the inner wall of the junction box 1. Several wiring grooves 9 are opened at the near ends of the upper and lower mounting plates 8. An arc-shaped plate 3 is arranged between the upper and lower wiring grooves 9. Several damping rods 10 are fixedly connected between the far ends of the upper and lower arc-shaped plates 3 and the inner walls of the upper and lower wiring grooves 9. A spring 11 is sleeved on the outside of each damping rod 10. The spring 11 has a certain buffering effect. The two ends of the upper and lower springs 11 are fixedly connected to the arc plate 3 and the inner wall of the wiring groove 9, respectively.

[0033] Then, protrusions 12 are fixedly connected to the middle of the upper ends of both sides of the upper mounting plate 8. A lead screw 13 is threadedly connected to one side of the protrusion 12, and a guide rod 14 is slidably connected to the other side of the protrusion 12. The upper and lower ends of the lead screw 13 are rotatably connected to the inner wall of the wire box 1, and the upper and lower ends of the guide rod 14 are fixedly connected to the inner wall of the wire box 1. In order to drive the lead screw 13 to rotate, a handwheel 15 is rotatably connected to one side of the upper end of the wire box 1. The lower end of the handwheel 15 extends through the wire box 1 to the outside and is fixedly connected to the upper end of the lead screw 13. The handwheel 15 is limited by a limiting component, which includes a bolt 16. The bolt 16 is threadedly connected to the handwheel 15. Several limiting holes 17 are provided below the handwheel 15 and are distributed on the outer periphery of the wire box 1. The bolt 16 and the limiting holes 17 are used in conjunction.

[0034] First, the busbar is passed between the upper and lower arc plates 3. Then, by rotating the handwheel 15, the lead screw 13 is driven to rotate. Since the protrusion 12 is threaded onto the lead screw 13, the protrusion 12 drives the upper mounting plate 8 to move downward. The guide rod 14 plays a guiding role, ensuring the correct movement direction of the mounting plate 8. After the upper and lower arc plates 3 are in contact with the busbar, continue to rotate the handwheel 15 to compress the spring 11 and the damping rod 10, causing the spring 11 and the damping rod 10 to deform. This provides a certain degree of buffering for the clamping force, protects the busbar, and prevents over-clamping and damage to the outer circumference of the busbar. Continue to rotate the handwheel 15 until the busbar is completely fixed. This method has a strong adaptability and can complete the wiring of busbars of different diameters. In order to limit the completed wiring, rotate the bolt 16 to move it downward until the bolt 16 extends into one of the limiting holes 17, thus locking the position of the handwheel 15 and the upper mounting plate 8.

[0035] Next, the connecting device 4 includes a connecting groove 5 and a connecting rod 6 that cooperate with each other. The connecting device 4 completes the connection of multiple wire boxes 1 by limiting the connecting rod 6 in the connecting groove 5. The connecting device 4 is set on both sides of the wire box 1, and the two sides of the connecting device 4 are symmetrically arranged. The connecting rod 6 is fixedly connected to the upper and lower parts of the front end of the wire box 1, and the connecting groove 5 is opened on both sides of the rear end of the wire box 1.

[0036] Then, the connecting device 4 also includes two connecting blocks 18. The connecting blocks 18 are fixedly connected to the rear of both sides of the junction box 1. The near ends of the two connecting blocks 18 extend into the connecting groove 5. The connecting blocks 18 each have a cavity 19 inside. The upper and lower ends of the inner wall of the cavity 19 are fixedly connected to a fixing rod 20. The upper and lower parts of the fixing rod 20 are slidably connected to a pressing rod 21. The disjoint ends of the upper and lower pressing rods 21 extend through the cavity 19 to the outside. The front end of the pressing rod 21 is fixedly connected to a limit block 22. The connecting rod 6 has a second limit hole 23. The limit block 22 and the inner wall of the cavity 19 are slidably connected. The upper and lower limit blocks 22 extend through the cavity 19 to the outside. The limit block 22 and the second limit hole 23 are used in conjunction. The near ends of the upper and lower limit blocks 22 are connected by a second damping rod 24. The outer side of the second damping rod 24 is sleeved with a second spring 25. The upper and lower ends of the second spring 25 are fixedly connected to the upper and lower limit blocks 22 respectively.

[0037] When the cable length needs to be extended according to the cabling requirements, first place the two junction boxes 1 side by side, then press the upper and lower pressing rods 21. As the upper and lower pressing rods 21 move towards the same side, the upper and lower limiting blocks 22 move accordingly, compressing the second spring 25 and the second damping rod 24, until the upper and lower limiting blocks 22 are completely moved into the cavity 19. Then, push one of the junction boxes 1 so that the connecting rod 6 is inserted into the connecting groove 5. After the connecting rod 6 is completely slid into the connecting groove 5, release the pressing rod 21. Under the rebound force of the second spring 25 and the second damping rod 24, the upper and lower limiting blocks 22 are pushed into the upper and lower limiting holes 23, so that the connecting rod 6 is locked in the connecting groove 5, completing the splicing connection. This is to adapt to different cabling requirements and install busbars of different lengths. It is simple, quick, and highly practical.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
