Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet component technology, specifically to a power distribution cabinet wiring component and the power distribution cabinet thereof. Background Technology

[0002] The wiring components of the distribution cabinet are a crucial part of the distribution cabinet. They are responsible for safely and effectively distributing electrical energy to various electrical devices. The number of wiring channels in the distribution cabinet should be minimized. At the same time, parallel wires should be grouped together according to the main and control circuits, arranged in a single layer, and laid close to the mounting surface. The wiring sequence is generally centered on the contactor, from the inside out, from high to low, first the control circuit, then the main circuit, with the principle of not interfering with subsequent wiring.

[0003] For example, patent application number 202021747952.7 published on the China Patent Network, entitled "Distribution Cabinet Wiring Assembly and Distribution Cabinet," includes two fixed beams and multiple movable beams. The two fixed beams are spaced apart and fixed to the inner wall of the cabinet door, with parallel axes. Each fixed beam has multiple mounting positions spaced along its axis. The multiple movable beams are spaced apart along the axis of the fixed beams, and each movable beam's two ends are detachably connected to one of the mounting positions on the two fixed beams. The movable beams are used for binding wire harnesses or installing wire troughs. This distribution cabinet wiring assembly reduces wiring difficulty and improves wiring efficiency. The solution also provides a distribution cabinet using the aforementioned wiring assembly.

[0004] Existing wiring assemblies are primarily fixed to the distribution cabinet via threaded connections, which requires numerous holes to be drilled on the cabinet's surface for these connections. These holes not only compromise the cabinet's integrity but may also reduce its structural strength, making it more susceptible to damage from external forces. This problem is particularly pronounced in applications requiring high structural strength.

[0005] Secondly, users need to frequently disassemble and reinstall the threaded assembly during the process of adjusting the height of the wiring assembly. This not only increases the complexity of the operation but also extends the working time. Especially in situations where the height of the wiring assembly needs to be adjusted frequently, this problem can cause great inconvenience to users. In addition, frequent disassembly and installation may also lead to damage or loosening of the threaded assembly, thereby affecting the stability and reliability of the connection.

[0006] Finally, the cabling assembly and the cable are primarily connected via clips. However, different cable sizes require different clamping strengths, which makes it difficult to connect cabling assemblies to cables of different sizes. Insufficient clamping strength may result in a weak connection; while excessive clamping strength may damage the cable or the cabling assembly. Therefore, the applicability of existing cabling assemblies is somewhat limited.

[0007] Therefore, it is necessary to redesign and modify the wiring components of the power distribution cabinet and the power distribution cabinet itself. Summary of the Invention

[0008] To address the problems mentioned in the background section, the present invention aims to provide a power distribution cabinet wiring assembly and a power distribution cabinet thereof, which has the advantages of easy adjustment and installation.

The top of the adjusting rod passes through the lifting plate and is slidably connected to the lifting plate. A threaded sleeve located at the bottom of the lifting plate is threaded onto the surface of the adjusting rod. The threaded sleeve can support the lifting plate and keep its height constant.

[0018] In a preferred embodiment of the present invention, the top of the bearing plate is movably connected to a toothed column via a bearing. The toothed column is located inside the guide rod, and the top of the screw is fixedly connected to a driven wheel located on the front of the toothed column.

[0048] As a technical optimization of the present invention, the linkage between the push plate 8 and the sealing frame 14 is realized through the mutual meshing of the gear 15, the vertical plate 16 and the toothed plate 17, so that the state of the sealing frame 14 can be automatically adjusted while the position of the push plate 8 is adjusted, thereby improving the convenience and efficiency of operation.

[0049] refer to Figure 8 Guide wheels 18 are provided on both sides of the top of the connecting plate 3. Traction ropes 19 are fixedly connected to both sides of the top of the push plate 8.

The surface of the pressure plate 5 is fixedly connected to the protrusion 20. The end of the traction rope 19 away from the guide wheel 18 is fixedly connected to the protrusion 20. When the push plate 8 moves downward and releases the pressure plate 5, the push plate 8 can use the traction rope 19 to pull the pressure plate 5 to keep it in an elastic connection and positioning state, preventing the pressure plate 5 from sliding and falling when it loses its dry compression.

[0050] As a technical optimization of the present invention, the arrangement and function of components such as guide wheel 18, traction rope 19 and protrusion 20 can prevent the pressure plate 5 from sliding and falling when it loses pressure, thereby enhancing the stability and safety of the pressure plate 5 and ensuring the reliability of cable fixing.

[0051] refer to Figure 1 A power distribution cabinet includes a cabinet body 21. The cabinet body 21 has a connecting structure 22 inside. Several wiring structures 1 are installed on the cabinet body 21 through the connecting structure 22. The connecting structure 22 includes a support plate 24 installed inside the cabinet body 21 through a flip structure 23. Guide rods 25 are fixedly connected to both sides of the top of the support plate 24. The top of the guide rods 25 passes through a push plate 8 and a bracket 4 in sequence and is slidably connected to the two. The flip structure 23 can use the support plate 24 to carry the wiring structures 1 to the outside of the cabinet body 21 for disassembly and assembly.

[0052] As a technical optimization of the present invention, the connection structure 22 inside the cabinet 21 enables the wiring structure 1 to be easily installed and disassembled, thereby improving the maintainability and scalability of the power distribution cabinet.

[0053] refer to Figure 2 The flipping structure 23 includes a lifting plate 26 disposed inside the cabinet 21. Connecting blocks 27 are fixedly connected to both sides of the top of the lifting plate 26. The bearing plate 24 is located inside the connecting blocks 27. A transmission rod 28 is fixedly connected inside the bearing plate 24. Both ends of the transmission rod 28 pass through the connecting blocks 27 and extend to the outside of the connecting blocks 27. The bearing plate 24 can swing around the transmission rod 28 as the axis inside the connecting blocks 27 and carry the wiring structure 1 to the outside of the cabinet 21.

[0054] As a technical optimization of the present invention, the interaction of components such as lifting plate 26, connecting block 27, transmission rod 28 and bearing plate 24 enables the flipping and movement of wiring structure 1, making the installation and disassembly of wiring structure 1 more convenient and improving work efficiency.

[0055] refer to Figure 3 Both ends of the shaft 12 are fixedly connected to a fork 29. The top of the fork 29 is set to be tilted backward and the bottom has a vertical path. The cabinet 21 is fixedly connected to a limit rod 30. The fork 29 is sleeved on the surface of the limit rod 30 and slidably connected to the limit rod 30. After the support plate 24 carries the fork 29 down, the limit rod 30 on its inner side can contact the inclined surface of the fork 29 and push the fork 29 to swing forward automatically by using the inclined squeezing force. Both sides of the bottom of the inner wall of the cabinet 21 are fixedly connected to an adjusting rod 31. The top of the adjusting rod 31 passes through the lifting plate 26 and is slidably connected to the lifting plate 26. The surface of the adjusting rod 31 is threadedly connected to a screw sleeve 32 located at the bottom of the lifting plate 26. The screw sleeve 32 can support the lifting plate 26 to keep its height constant.

[0056] As a technical optimization of the present invention, the automatic swinging and positioning of the bearing plate 24 during the descent process is realized through the setting and function of components such as the shift fork 29, the limit rod 30, the adjusting rod 31 and the screw sleeve 32, which not only simplifies the operation process, but also improves the automation level of the power distribution cabinet.

[0057] refer to Figure 3 The top of the bearing plate 24 is movably connected to a toothed column 33 via a bearing. The toothed column 33 is located inside the guide rod 25. The top of the screw 7 is fixedly connected to a driven wheel 34 located on the front of the toothed column 33. The driven wheel 34 meshes with the toothed column 33.

[0058] As a technical optimization of the present invention, by describing the composition and working principle of components such as the toothed column 33 and the driven wheel 34, the screw 7 can be driven and adjusted, making the adjustment of the wiring structure 1 more flexible and precise, and improving the adaptability and reliability of the power distribution cabinet.

[0059] refer to Figure 4 A drive motor 35 is mounted on the bottom of the support plate 24 via a frame. The output end of the drive motor 35 is fixedly connected to a wheel 36. The bottom end of the toothed column 33 extends through to the bottom of the support plate 24 and is fixedly connected to a drive wheel 37. The surfaces of the drive wheel 37 and the wheel 36 are both provided with teeth and mesh with each other through the teeth.

[0060] As a technical optimization of the present invention, by setting a transmission motor 35 and a wheel 36, the gear column 33 can be controlled to rotate automatically, and multiple screws 7 on the surface of the wiring structure 1 can be driven simultaneously.

[0061] The working principle and usage process of this invention are as follows: In use, the user first operates the screw sleeve 32 inside the cabinet 21. The screw sleeve 32 on the surface of the adjusting rod 31 adjusts the height of the lifting plate 26 by rotation. The lifting plate 26 descends under its own weight. At this time, the limiting rod 30 moves within the vertical path at the bottom of the shift fork 29, keeping the support plate 24 connected to the shift fork 29 vertically descending. Simultaneously, the guide rod 25 at the top of the support plate 24 disengages from the cabinet 21 during the descent. When the limiting rod 30 moves to the inside of the continuously moving inclined end of the shift fork 29, the inclined surface at the bottom of the shift fork 29 contacts the limiting rod 25 inside the cabinet 21. When the lever 30 contacts, it pushes the shift fork 29 to swing forward. With the transmission rod 28 as the axis, the support plate 24 can swing outward to the outside of the cabinet 21, facilitating maintenance or replacement of wiring components. When the top of the guide rod 25 on the top of the support plate 24 is exposed to the external environment of the cabinet 21, the user inserts the wiring structure 1 onto the surface of the guide rod 25 through the holes on the surface of the bracket 4 and the connecting plate 3, and rotates the screw sleeve 32 in the opposite direction. The screw sleeve 32 moves upward and presses against the lifting plate 26, causing it to push the support plate 24 back to its original position and remain vertical. After the flipping structure 23 is adjusted, the user pushes the wiring structure 1 to make it vertical on the surface of the guide rod 25. As the cable slides straight down, the traction rope 19 applies an outward pulling force to the pressure plate 5, allowing the pressure plate 5 to maintain frictional positioning with the cabinet 21, preventing the wiring structure 1 from falling directly. When multiple wiring structures 1 reach the appropriate position, the cable is inserted into the cable tray 2 to initially fix the position and start the drive motor 35. Its output wheel 36 drives the drive wheel 37 through tooth meshing, causing the toothed column 33 to rotate. The toothed column 33 meshes with the driven wheel 34 at the top of the screw 7, synchronously driving the screws 7 of multiple wiring components to rotate. The screws 7 drive the push plate 8 to move upward, and the rollers 1 on both sides of the push plate 8... The pressure plate 9, which is inclined inside the pressure plate 5, contacts the pressure plate 5 and squeezes it outward, causing it to swing and stick tightly to the inner wall of the distribution cabinet or the bracket 4, thus completing the positioning and fixing of the cable tray 2. When the push plate 8 moves upward, the upright plate 16 fixed on its front moves upward synchronously, driving the toothed plate 17 on the upright plate 16 to mesh with the gear 15 on the surface of the shaft 12. The gear 15 rotates, driving the shaft 12 to rotate. The movable blocks 13 at both ends of the shaft 12 drive the sealing frame 14 to swing towards the cable tray 2, forming a closed groove with the cable tray 2, clamping the internal cables, thereby achieving the effect of continuous connection and fixing of the wiring structure 1, the cabinet 21, and the cables.

[0062] In summary, the wiring assembly and the wiring cabinet of this power distribution cabinet have a cable tray 2, which can clamp cables, and the connection plate 3, bracket 4 and pressure plate 5 are used to fix and position the cables, making the wiring neater and more orderly, and improving the wiring efficiency and safety of the power distribution cabinet.
