Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to an adjustable cable routing mechanism for high and low voltage distribution cabinets. Background Technology

[0002] As the core equipment in a power system for power distribution, control, and protection, distribution cabinets are widely used in industries, buildings, and infrastructure. They typically integrate electrical components such as circuit breakers, contactors, relays, and meters. Through a rational layout and connection with the wiring, they perform functions such as circuit switching control, load distribution, overload protection, and power metering. The standardization of their internal structure and the rationality of their wiring layout directly affect the operational safety and maintenance efficiency of the power system.

[0003] During the installation of existing distribution cabinets, components such as circuit breakers, contactors, relays, and meters need to be fixed inside the cabinet before electrical connections between them are established via wires. However, due to the limited internal space and dense component layout of the distribution cabinet, the complex wiring often significantly increases the installation difficulty. Operators must thread, bundle, and secure multiple wires within a limited area, which can easily lead to confusion due to tangled wires. Messy wiring makes subsequent maintenance, component replacement, or troubleshooting difficult. For example, unclear wiring markings or overlapping paths may lead to misoperation, and even poor heat dissipation may increase the risk of short circuits.

[0004] Currently, traditional power distribution cabinets rely heavily on pre-drilled fixed through-holes in the cabinet for wiring. During installation, operators must thread wires through these holes one by one and connect them to the corresponding components. However, the position and size of these through-holes are fixed and cannot be flexibly adjusted according to actual needs. If the wiring plan deviates or equipment needs to be added or removed temporarily, operators have to unplug the wires and re-thread them, which is not only inefficient but also prone to damage due to repeated pulling. Furthermore, the arrangement of fixed through-holes is difficult to adapt to different component sizes or diverse wiring requirements, often resulting in redundant cable accumulation or a chaotic layout, further exacerbating the messiness of the installation process. Utility Model Content

[0005] To overcome the drawbacks of fixed through holes being non-adjustable and messy wiring management, this utility model provides an adjustable cable routing mechanism for high and low voltage distribution cabinets, aiming to solve the above-mentioned shortcomings.

[0006] An adjustable cable management mechanism for high and low voltage distribution cabinets includes a cable management frame disposed inside the distribution cabinet with its opening facing the cabinet door. Two hollow columns on the left and right sides of the cable management frame are each rotatably connected to a lead screw. An adjustment knob is connected to the front end of one of the lead screws, and a pulley assembly is connected to the rear ends of both lead screws. A cable management plate is slidably connected to the two hollow columns of the cable management frame, and both ends of the cable management plate are threadedly connected to the lead screws. The cable management plate has multiple U-shaped slots facing the cabinet door. Buckles are slidably connected inside the cable management plate, located on the left and right sides of each U-shaped slot. A first spring is connected to one end of each buckle inserted into the cable management plate, and the other end of the first spring is connected to the cable management plate. The cable management plate is equipped with a locking component for locking the wires.

[0007] As an improvement to the above solution, the locking component includes a locking plate. Several fixing buckles are slidably connected inside the ribbon cable plate. The fixing buckles are located in the middle of each "U"-shaped through slot, and the end of the fixing buckle inserted into the ribbon cable plate is arc-shaped. A rack is connected inside the ribbon cable plate. The locking plate is slidably connected to the left and right sides of the fixing buckle through a round rod. A locking tooth is provided on the side of the locking plate on both sides of the fixing buckle that is separated. The locking tooth engages with the rack. A second spring is sleeved on the round rod of the locking plate. One end of the second spring is connected to the fixing buckle, and the other end is connected to the locking plate.

[0008] As an improvement to the above solution, a gasket is connected to the arc surface of the rear end of the fixing buckle.

[0009] As an improvement to the above solution, the cable tray has mounting parts connected to the upper and lower sides of the two hollow columns on the left and right sides, and the cable tray is installed in different positions in the power distribution cabinet through a number of mounting parts.

[0010] As an improvement to the above solution, handles are connected to the top of the two hollow columns on the left and right sides of the cable tray.

[0011] As an improvement to the above solution, the rear end of the buckle is provided with an arc surface, the radius of which is the same as that of the arc of the "U" shaped groove, and the front end of the buckle is provided with an inclined surface, the boundary of which coincides with the boundary of the arc surface.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. By adjusting the knob through the lead screw and pulley assembly, the lead screw on one side is driven to rotate, causing the cable tray to slide back and forth along the hollow column of the cable tray frame. This allows for stepless adjustment of the front and back positions of the cable tray, dynamically adjusting the cable layout, significantly improving installation efficiency and reducing the risk of wire damage.

[0014] 2. The wire is guided into the "U" shaped groove by the buckle bevel and then clamped by the spring; the wire is pressed by the rack engagement of the locking component and the spring rebound. The double fixation of the buckle and the locking component ensures that the wire is arranged in an orderly manner along the "U" shaped groove path. The rack engagement can lock the fixing buckle at any position, reduce the accumulation of redundant cables, and improve the convenience of maintenance and the long-term stability of the system.

Detailed Implementation

[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] Example: An adjustable cable management mechanism for high and low voltage distribution cabinets, such as... Figures 1-3As shown, the distribution cabinet includes a cable tray 1, an adjusting knob 2, a lead screw 3, a pulley assembly 4, a cable tray plate 5, a buckle 6, a first spring 7, and a locking assembly. Several "U"-shaped cable trays 1 are installed inside the distribution cabinet, with the openings of the cable tray 1 facing the cabinet door. Lead screws 3 are rotatably connected to the two hollow columns on the left and right sides of the cable tray 1. The front end of one lead screw 3 is connected to the adjusting knob 2, and the rear ends of both lead screws 3 are connected to the pulley assembly 4. The pulley assembly 4 synchronously transmits power to the other lead screw 3, causing both lead screws 3 to rotate synchronously. The cable tray plate 5 is slidably connected to the two hollow columns on the left and right sides of the cable tray 1. The cable tray 5 is threaded to the lead screw 3 at both ends. The forward and backward movement of the cable tray 5 can adapt to the installation requirements of different electrical components. At the same time, the synchronous transmission of the pulley group 4 ensures that the cable tray 5 moves horizontally, preventing the cable from coming loose due to tilting force. The cable tray 5 has multiple "U"-shaped slots facing the cabinet door. The cable tray 5 is slidably connected to the buckle 6. The buckle 6 is located on the left and right sides of each "U"-shaped slot. One end of the buckle 6 inserted into the cable tray 5 is connected to the first spring 7. The other end of the first spring 7 is connected to the cable tray 5. The cable tray 5 is equipped with a locking component for locking the wire.

[0021] like Figure 2 and Figure 3 As shown, the locking assembly includes a retaining buckle 8, a locking plate 9, a rack 10, and a second spring 11. Several retaining buckles 8 are slidably connected within the cable tray 5. Each retaining buckle 8 is located in the middle of a U-shaped slot, and the end of the retaining buckle 8 inserted into the cable tray 5 is arc-shaped, with the radius of the arc matching the radius of the U-shaped slot. A rack 10 is connected within the cable tray 5. The locking plate 9 is slidably connected to the left and right sides of the retaining buckle 8 via a round rod. A locking tooth is provided on the side of the locking plate 9 on both sides of the same retaining buckle 8 where they are separated. The locking tooth engages with the rack 10. A second spring 11 is sleeved on the round rod of the locking plate 9, with one end connected to the retaining buckle 8 and the other end connected to the locking plate 9. Simultaneously pinching the locking plates 9 on both sides of the retaining buckle 8 causes the locking plates 9 to slide along the round rod and compress the second spring 11, disengaging the locking teeth on the locking plate 9 from the rack 10. Once the retaining clip 8 is fully pushed into the target position, the locking plate 9 is released, and the second spring 11 pushes the locking plate 9 back to its original position. The locking teeth re-engage with the rack 10, locking the retaining clip 8 in place. The continuous toothed design of the rack 10 allows the retaining clip 8 to achieve stepless positioning within the cable tray 5, ensuring that the wires are pressed tightly within the "U"-shaped groove, preventing the cables from shifting due to vibration or pulling.

[0022] like Figure 2 As shown, it also includes a gasket 12. The rear arc surface of the fixing buckle 8 is connected to the gasket 12. The gasket 12 increases the contact area through elastic deformation, disperses the clamping force, and avoids the wire insulation layer being scratched due to rigid contact.

[0023] like Figure 2As shown, it also includes mounting parts 13. The two hollow columns on the left and right sides of the cable tray 1 are connected to the mounting parts 13 on the upper and lower sides. The mounting parts 13 are slide rail or bolt connection structures, which allow the cable tray 1 to be vertically adjusted in the distribution cabinet.

[0024] like Figure 2 As shown, it also includes handles 14, and handles 14 are connected to the top of the two hollow columns on the left and right sides of the cable tray 1.

[0025] The rear end of the clip 6 has an arc surface, the radius of which is the same as the arc of the "U"-shaped groove. The front end of the clip 6 has a bevel, the boundary of which coincides with the boundary of the arc surface. The arc surface at the rear end of the clip 6 and the inner wall of the "U"-shaped groove form a continuous closed curved surface, ensuring that the wire is completely wrapped and eliminating the risk of lateral cable movement. The bevel design at the front end reduces the resistance when inserting the wire and prevents the clip 6 from jamming due to angle deviation. When the wire is pulled out, the bevel guides the clip 6 to expand smoothly outward, reducing frictional damage to the wire. At the same time, the preload of the first spring 7 maintains the dynamic balance of the clamping force, ensuring that the wire is not easily loosened and is easy to operate during adjustment.

[0026] When installing the distribution cabinet, the staff first determines the installation position of each electrical component. Through reasonable layout and wiring connection, the function of the distribution cabinet is realized. The ends of the wires are connected to the electrical components, while the middle part needs to be properly fixed. After the wires are connected to each electrical component, the wires are pushed into the nearby "U"-shaped groove. After the wires contact the inclined surface of the clip 6, the clip 6 is pushed to slide to both sides, compressing the first spring 7. After the wires pass through the clip 6, they contact the inside of the "U"-shaped groove. The first spring 7 rebounds, pushing the clips 6 on both sides to slide to the middle, preventing the wires from detaching from the cable tray 5. When connecting the other end of the wire, the wire is pulled, and the wire slides in the cable tray 5. After all electrical components are installed and the wires are connected, the wires are sorted. When a wire needs to be removed, the wire is pulled forward to push the clip 6 open along the inclined surface. The clip 6 compresses the first spring 7 again, and the wire slides out freely after being clamped. This process is repeated to adjust the position of the wires to meet the requirements of sorting and classification.

[0027] After the position of the wire is determined, the fixing buckle 8 is pushed in at once. The clamping plates 9 on both sides of the fixing buckle 8 engage with the rack 10. The worker pinches the clamping plates 9 on both sides, which compress the second spring 11. Then, the clamping plates 9 are pushed into the cable tray 5. After the pad 12 at the end of the fixing buckle 8 is squeezed against the wire, the clamping plate 9 is released. The second spring 11 rebounds and pushes the clamping plate 9 to engage with the rack 10, thereby fixing the position of the clamping plate 9, restricting the movement of the fixing buckle 8, and completing the fixing of the wire.

[0028] When adding, disassembling, or replacing electrical components, pinch the clips 9 on both sides of the fixing buckle 8 to disengage the clips 9 from the rack 10, and pull out the fixing buckle 8 to release the restriction on the wires. If some electrical components are too large and the position of the cable tray 1 and cable plate 5 needs to be adjusted, turn the adjustment knob 2. The pulley group 4 will drive the two lead screws 3 to rotate synchronously. The threads of the lead screws 3 will engage with the threaded holes at both ends of the cable plate 5, causing the cable plate 5 to slide back and forth along the hollow column of the cable tray 1 to adjust the position of the cable plate 5. The cable tray 1 is connected to the inner wall of the distribution cabinet through the mounting part 13. When it is necessary to adjust the horizontal or vertical position of the cable tray 1, the operator can loosen the fixing bolts of the mounting part 13, grasp the handle 14 on the top of the cable tray 1 and move it to the new position, and then tighten the bolts again.
