Technical Field

[0001] This utility model relates to the field of electrical installation auxiliary equipment technology, specifically to a wire trough partition and fixing device. Background Technology

[0002] With the rapid development of power, communication and intelligent systems, cable trays, as the core carrier for cable laying, are widely used in data centers, industrial plants, commercial buildings and residential buildings. Their core functions are to provide physical protection for cables, standardize wiring paths, and prevent electromagnetic interference (EMI) and mechanical damage.

[0003] However, existing cable trays typically only have simple openings or perforations at the inlet and outlet ends, without being equipped with dedicated cable positioning components. Repeated friction or bending of cables at the openings may damage the insulation layer, causing short circuits or leakage accidents. Therefore, we need to propose a cable tray separation and fixing device. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tray separation and fixing device. By setting up a multi-group branching assembly on the side wall of the tray plate and a clamping assembly on two sets of U-shaped positioning frames, the branching assembly realizes the pre-bundling of cables according to needs to clarify the path, reduce the difficulty of maintenance, and improve management efficiency. The clamping assembly provides secondary positioning of the cables at the inlet and outlet ends to limit displacement and prevent offset accumulation. Together, they prevent the cables from shaking, reduce friction and excessive bending, and achieve the effect of standardizing the cable layout along the entire path, reducing the risk of insulation damage and short circuit leakage, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cable tray partitioning and fixing device includes: a tray plate, on one side wall of which are provided several sets of cable splitting components for positioning cables in bundles; two sets of U-shaped positioning frames are fixedly connected to one side wall of the tray plate, and the two sets of positioning frames and the tray plate are respectively provided with inlet and outlet ends, and the side walls of the two sets of U-shaped positioning frames are respectively provided with clamping components for positioning the cables laid in the inlet and outlet ends; and a tray cover plate is detachably connected to one side wall of the tray plate.

[0006] Preferably, the clamping assembly includes a screw sleeve, which is fixedly embedded in one side wall of the U-shaped positioning frame. The screw sleeve is internally threaded with a screw rod, one end of which is rotatably connected to a pressure plate, and the other end of which is fixedly connected to a knob.

[0007] Preferably, a first rubber pad is fixedly connected to one side wall of the groove plate, and a second rubber pad corresponding to the first rubber pad is provided on one side wall of the pressure plate, with the laid cable located between the first rubber pad and the second rubber pad.

[0008] Preferably, the inner wall of the C-shaped positioning frame is provided with a guide groove, and a protrusion adapted to the guide groove is fixedly connected to one side wall of the pressure plate, and the protrusion is slidably connected inside the guide groove.

[0009] Preferably, the outer wall of the knob is provided with anti-slip texture.

[0010] Preferably, the branching assembly includes a positioning plate, which is fixedly connected to one side wall of the slot plate, and a plurality of wire clamps are fixedly connected to one side wall of the positioning plate.

[0011] Preferably, a number of sets of buckles are provided on one side of the groove cover plate, and a number of sets of slots adapted to the buckles are opened on one side wall of the groove plate, and the buckles are engaged in the inside of the slots.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a multi-group cable management assembly installed on the side wall of the cable tray to pre-bundle cables entering the tray according to their function and specifications, preventing multiple cables from tangling and being squeezed together inside the tray. This design clearly defines the wiring path of each cable bundle, significantly reducing the difficulty of cable management during later maintenance and improving cable management efficiency. The inlet and outlet ends formed by two sets of U-shaped positioning frames and the cable tray, along with the clamping components on them, can perform secondary positioning of the cables entering and exiting the tray. Through the action of the clamping components, the displacement of the cables at the tray ports can be effectively limited, preventing the cables from shifting or piling up at the ports due to external pulling, ensuring the stability and standardization of the cable entry and exit paths. The cable bundling and positioning by the cable management assembly, and the fixing of the cables at the ports by the clamping components, can prevent the cables from shaking randomly inside the tray. This significantly reduces the friction frequency between the cables and the inner wall of the tray, as well as other cables, reducing the risk of short circuits and leakage caused by friction damage to the cable insulation layer. At the same time, the positioning and fixing at the ports can also limit the bending angle of the cables, preventing excessive bending from damaging the internal conductors.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3 This utility model provides a technical solution: A cable tray partitioning and fixing device includes: a tray plate 1, on one side wall of which are provided several sets of cable splitting components 2 for positioning cables in bundles; two sets of C-shaped positioning frames 3 are fixedly connected to one side wall of the tray plate 1, and the two sets of positioning frames 3 and the tray plate 1 are respectively reserved with inlet and outlet ends, and the two sets of C-shaped positioning frames 3 are respectively provided with clamping components 4 for positioning the cables laid in the inlet and outlet ends; and a tray cover plate 5 is detachably connected to one side wall of the tray plate 1.

[0017] By setting up the cable distribution component 2 to bundle the cables inside the channel, the clamping component 4 to fix the port cables, and the detachable channel cover plate 5 to form a closed protective structure, a combined effect of orderly positioning and safety protection of the cable throughout the entire path is achieved. The overall structure adopts a modular design concept. The channel plate 1 serves as the core load-bearing foundation and can be spliced ​​according to the channel length requirements. The U-shaped positioning frame 3 is fixed to the channel plate 1 by welding or bolting to ensure connection strength. The gap between the channel cover plate 5 and the channel plate 1 does not exceed 2mm, which ensures both sealing and easy disassembly and assembly, adapting to the cable laying requirements in different scenarios.

[0018] The clamping assembly 4 includes a threaded sleeve 401, which is fixedly embedded in one side wall of the U-shaped positioning frame 3. A screw 402 is threadedly connected to the inside of the threaded sleeve 401. One end of the screw 402 is rotatably connected to a pressure plate 403, and the other end is fixedly connected to a knob 404. By setting the threaded fit between the threaded sleeve 401 and the screw 402, and the rotatable connection between the screw 402 and the pressure plate 403, rotating the knob 404 drives the pressure plate 403 to move linearly, achieving precise adjustment of the cable clamping force. The threaded sleeve 401 is embedded in the U-shaped positioning frame 3 with an interference fit to prevent loosening or displacement under force. A deep groove ball bearing is provided at the connection between the screw 402 and the pressure plate 403, ensuring that the pressure plate 403 only moves linearly when the screw 402 rotates. The thread uses a fine-pitch structure, and the pressure plate 403 moves no more than 2mm with each rotation of the knob 404, achieving micron-level clamping force adjustment.

[0019] A first rubber pad 6 is fixedly connected to one side wall of the channel plate 1, and a second rubber pad 7 corresponding to the first rubber pad 6 is provided on one side wall of the pressure plate 403. The cable is located between the first rubber pad 6 and the second rubber pad 7. By setting the corresponding first rubber pad 6 and second rubber pad 7 to clamp the cable, the elastic buffering properties of rubber are utilized to achieve the dual effect of avoiding damage to the cable insulation layer by the rigid compression of the pressure plate 403, while enhancing the frictional fixing effect. Both the first rubber pad 6 and the second rubber pad 7 are made of oil-resistant rubber with a Shore hardness of 50-60, with fine anti-slip bumps on the surface, and a thickness of 3-5mm, which can accommodate cables with a diameter of 2-20mm. The rubber pads are fixed to the channel plate 1 and the pressure plate 403 respectively with environmentally friendly adhesive, and the peel strength is not less than 5MPa to ensure that they will not fall off during long-term use.

[0020] A guide groove 8 is provided on the inner wall of the U-shaped positioning frame 3. A protrusion 9, which matches the guide groove 8, is fixedly connected to one side wall of the pressure plate 403. The protrusion 9 is slidably connected inside the guide groove 8. By setting the sliding engagement between the guide groove 8 and the protrusion 9, the movement trajectory of the pressure plate 403 is restricted, thereby preventing the pressure plate 403 from shifting during lifting and ensuring its precise alignment with the rubber pad. The guide groove 8 has a T-shaped structure, and the protrusion 9 is correspondingly set as a T-shaped slider. The gap between the two is controlled at 0.1-0.2mm, which ensures smooth sliding and avoids shaking. The length of the guide groove 8 matches the maximum stroke of the pressure plate 403, and limit protrusions are provided at both ends to prevent the protrusion 9 from sliding out of the groove, further improving the stability of the structure during operation.

[0021] The outer wall of knob 404 is equipped with anti-slip texture. This texture increases the coefficient of friction between the hand and the knob, allowing operators to easily turn it without tools and improving ease of operation. The anti-slip texture features a spiral ridge design with a ridge height of 1.5mm and a spacing of 3mm, enhancing the anti-slip effect while preventing hand scratches. Knob 404 is injection molded from ABS engineering plastic with an outer diameter of 30-40mm. The curved grip surface conforms to the palm of the hand, allowing for cable tightening or loosening with a single operation, making it suitable for complex operating environments such as high-altitude work.

[0022] The cable distribution assembly 2 includes a positioning plate 201, which is fixedly connected to one side wall of the channel plate 1. Several sets of wire clamps 202 are fixedly connected to one side wall of the positioning plate 201. By setting the positioning plate 201 to support multiple sets of wire clamps 202, the cables are inserted one by one into the wire clamps 202, achieving the effect of classifying and bundling according to function or specification and avoiding cable tangling. The positioning plate 201 is made of 2mm thick cold-rolled steel plate, bent and formed, with galvanized surface treatment for rust prevention. 4-8 sets of wire clamps 202 are evenly distributed on each positioning plate 201. The wire clamps 202 are made of elastic PP material, with an opening width 1-2mm smaller than the cable diameter. They clamp the cable through elastic deformation. The distance between adjacent wire clamps 202 is not less than 10mm to ensure good heat dissipation and no interference between cables.

[0023] Several sets of latches 10 are provided on one side of the channel cover plate 5, and several sets of slots 11 adapted to the latches 10 are opened on one side wall of the channel plate 1. The latches 10 are engaged inside the slots 11. By setting the latches 10 and slots 11 to engage, the traditional bolt connection is replaced, achieving the effect of quick disassembly and assembly of the channel cover plate 5 and facilitating cable inspection and maintenance. The latches 10 are made of nylon 66 material, which has good elastic recovery. Each end of the channel cover plate 5 is provided with 2-3 sets of latches 10. The slots 11 are U-shaped slot structures with a depth of 5mm and barbs on the inner wall. The pull-out force after the latches 10 are engaged is not less than 15N, which can ensure the connection is firm and can be easily unlocked by pressing the end of the latches 10.

[0024] Working principle: Before installation, fix the cable tray 1 in the preset position according to the cable laying path, and then carry out the cable laying operation: First, insert the cable to be laid from the inlet end, and according to the cable function (such as high voltage, low voltage) or diameter specification, insert it one by one into the wire clamp 202 of the cable distribution assembly 2. The wire clamp 202 supported by the positioning plate 201 achieves preliminary cable bundling and positioning through elastic deformation, avoiding the cable from getting tangled inside the cable tray 1; after the cable passes through the inside of the cable tray 1, it comes out from the outlet end. The operator manually turns the knob 40. 4. Through the fine-pitch thread transmission of the screw sleeve 401 and the screw 402, the pressure plate 403 is driven to move downward along the guide structure formed by the guide groove 8 and the protrusion 9 until the second rubber pad 7 and the first rubber pad 6 are tightly attached to the cable surface. Utilizing the elastic buffering and anti-slip properties of the rubber pads, the cable is fixed for the second time while avoiding damage to the insulation layer, preventing external force from causing the cable to shift. Finally, the trough cover plate 5 is aligned with the trough plate 1 and pressed to make the buckle 10 snap into the slot 11, forming a closed space to prevent dust and debris from entering. When the cable needs to be inspected, simply press the buckle 10 to unlock and remove the trough cover plate 5. Turn the knob 404 to release the pressure plate 403 to adjust or replace the cable. The entire process does not require professional tools, realizing a convenient operation of the entire process of cable "bundling-fixing-protection-inspection".
