Description

Technical Field

[0001] This utility model relates to the field of cable positioning technology, specifically a cable positioning mechanism for use inside a power cabinet. Background Technology

[0002] As a core piece of equipment in a power system, the power cabinet undertakes the key functions of power distribution, control and protection. The layout and fixing quality of its internal cables directly affect the stability of equipment operation, maintenance efficiency and safety.

[0003] A search revealed a utility model patent with Chinese patent publication number CN222463795U, which discloses a cable positioning mechanism for use inside an electrical cabinet. The mechanism is applied to the body of the electrical cabinet, and a fixing plate is fixedly connected to the inner wall of the cabinet body by bolts. Multiple cable clamping components are slidably connected to one side of the fixing plate. Each cable clamping component includes a fixing block, a rubber clamp, and a fixing ring. The rubber clamp is fixedly connected to the fixing block, and the top and bottom of the fixing block are fixedly connected to the fixing ring. The fixing block is slidably connected to the fixing plate.

[0004] The aforementioned device uses a cable clamping assembly to locate cables. However, this structure can only locate the connecting parts, while cables in other parts inside the power cabinet are not restricted and inevitably become tangled together, making it impossible to locate them accurately. There is room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a cable positioning mechanism for the inside of a power cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable positioning mechanism for an internal power cabinet, comprising a cabinet body and a positioning component. The positioning component is located inside the cabinet body. The positioning component includes a vertical frame fixedly connected to the inner wall of the bottom of the cabinet body. Two horizontal frames are fixedly connected to the outer wall of the vertical frame near the cabinet body. Two vertically arranged limiting rods are fixedly connected inside the vertical frame. Two horizontally arranged limiting rods are also fixedly connected inside the two horizontal frames. Two positioning blocks 1 are slidably connected through the two vertically arranged limiting rods. Several positioning blocks 2 are slidably connected through the two adjacent horizontally arranged limiting rods. A restraining component is fixedly connected to the outside of each of the two positioning blocks 1 and the several positioning blocks 2. A connecting component is fixedly connected to the outside of each of the vertical frame and the two horizontal frames.

[0007] As a further preferred embodiment of this technical solution, the restraint assembly includes a mounting block fixedly connected to the outer wall of one end of the positioning block, a horizontally arranged pressure plate rotatably connected to the outside of the mounting block, a screw slidably connected inside the pressure plate, the screw being threadedly connected inside the positioning block, and a fixing structure provided outside the screw.

[0008] The ability to neatly confine all cables within the power cabinet significantly reduces troubleshooting time and maintains proper spacing between cables, preventing electromagnetic interference. External cables are passed through the cabinet and arranged side-by-side outside positioning block one, then aligned with the grooves on the outside of positioning block one. The cable arrangement principle is shown in the diagram: cables connecting to components closer to the bottom are placed on the inside, and cables connecting to components closer to the top are placed on the outside. When a cable reaches the desired connection point, it is laterally bent to bring it close to the horizontal frame, and then placed sequentially into the grooves on the outside of positioning block two. Supported by the vertical and horizontal frames, the cables maintain a neat arrangement, significantly reducing troubleshooting time. Maintenance personnel can access the target circuit without disassembling numerous cables, and tangled cables prevent electrical signal interference. Finally, the cables are secured using a binding component, preventing them from becoming loose.

[0009] As a further preferred embodiment of this technical solution, the fixing structure includes a top rod rotatably connected to the outside of the screw, the inner wall of the top of the top of the top rod being in contact with the outer wall of the top of the pressure plate, and a limiting groove being formed on the outer wall of the top of the positioning block, with a pressing block adapted to the top rod being slidably connected inside the limiting groove, the pressing block being located on one side of one of the limiting rods.

[0010] As a further preferred embodiment of this technical solution, a rubber pad is fixedly connected to the outer wall of each of the pressure plates at their closest points.

[0011] As a further preferred embodiment of this technical solution, the connecting component includes a plug strip fixedly connected to the bottom outer wall of the vertical frame, and the top outer wall of the vertical frame is provided with a limiting groove adapted to the plug strip.

[0012] If the height of the cabinet to be installed is much greater than the length of the vertical frame, you can pick up another vertical frame and connect the two using the connecting components. Align the plug strip at the bottom end of the new vertical frame with the limiting groove at the top of the original vertical frame, and then connect the two. At this time, the two vertical frames will be connected into a whole. They can only be pulled horizontally to disassemble. After the vertical frame is fixed inside the cabinet, the top vertical frame will be completely restricted and the state will be stable enough. The selection principle for the horizontal frame is the same as above. If the length is insufficient, you can use extension bolts to connect and reinforce it.

[0013] As a further preferred embodiment of this technical solution, two connecting pieces are fixedly connected to the bottom outer wall of the vertical frame and one side outer wall of each of the two horizontal frames.

[0014] As a further preferred embodiment of this technical solution, two horizontally arranged electrical component mounting plates are fixedly connected to the inner wall of one end of the cabinet, and the two electrical component mounting plates are respectively located above the two horizontal frames.

[0015] This utility model provides a cable positioning mechanism for use inside a power cabinet, which has the following advantages: (1) By setting up positioning components and binding components, this utility model can neatly restrict each cable inside the power cabinet, which can greatly shorten the troubleshooting time and keep each cable at a distance, thus avoiding electromagnetic interference. The external cables are passed through the cabinet and arranged in parallel outside the positioning block one. Then, they are aligned with the grooves outside the positioning block one. The cable arrangement principle is shown in the figure. The cables connected to the lower components are placed on the inside, and the cables connected to the upper components are placed on the outside. When the cable reaches the position to be connected, it is bent laterally to bring it close to the horizontal frame. Then, it is placed in the grooves outside the positioning block two. With the support of the vertical and horizontal frames, the cables can be neatly arranged, which can greatly shorten the troubleshooting time. The maintenance personnel do not need to disassemble a large number of cables to contact the target circuit. It can also avoid the interference of electrical signals caused by tangled cables. Finally, the binding components are used to fix the cables, so that the cables cannot become loose.

[0016] (2) By setting up a connecting component, if the height of the cabinet to be installed is much greater than the length of the vertical frame, another vertical frame can be picked up and the two can be connected by the connecting component. Align the plug strip at the bottom end of the new vertical frame with the limiting groove at the top of the original vertical frame, and then connect the two. At this time, the two vertical frames will be connected into a whole. They can only be pulled horizontally to disassemble. When the vertical frame is fixed inside the cabinet, the top vertical frame will be completely restricted and the state is stable enough. The selection principle of the horizontal frame is the same as above. If the length is insufficient, the connection can be reinforced by using extension bolts. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 2 , Figure 3 As shown in Figure 4, in this embodiment, a cable positioning mechanism for an internal power cabinet includes a cabinet body 1 and a positioning component 4. The positioning component 4 is located inside the cabinet body 1. The positioning component 4 includes a vertical frame 401 fixedly connected to the inner wall of the bottom of the cabinet body 1. Two horizontally arranged frames 402 are fixedly connected to the outer wall of the vertical frame 401 near the cabinet body 1. Two vertically arranged limiting rods 403 are fixedly connected inside the vertical frame 401. Two horizontally arranged limiting rods 403 are also fixedly connected inside the two horizontal frames 402. Two positioning blocks 404 are slidably connected through the two vertically arranged limiting rods 403. Several positioning blocks 405 are slidably connected through the two adjacent horizontally arranged limiting rods 403. A restraining component 5 is fixedly connected to the outside of the two positioning blocks 404 and the several positioning blocks 405. A connecting component 6 is fixedly connected to the outside of the vertical frame 401 and the two horizontal frames 402. Two horizontally arranged electrical component mounting plates 2 are fixedly connected to the inner wall of one end of the cabinet body 1. The two electrical component mounting plates 2 are respectively located above the two horizontal frames 402.

[0020] The external cables are passed through cabinet 1 and arranged side by side outside positioning block 404. Then, they are aligned with the grooves outside positioning block 404. The cable arrangement principle is shown in the figure. Cables connecting to components closer to the bottom are placed on the inside, and cables connecting to components higher up are placed on the outside. When the cable reaches the position to be connected, it is bent laterally to bring it close to the horizontal frame 402. Then, it is placed into the groove outside positioning block 405. With the support of the vertical frame 401 and the horizontal frame 402, the cables can maintain a neat arrangement, which can greatly shorten the troubleshooting time. Maintenance personnel can access the target circuit without disassembling a large number of cables. It can also avoid the interference of electrical signals caused by tangled cables. Finally, the cables are fixed with the binding component 5, so that the cables cannot become loose.

[0021] The restraint assembly 5 includes a mounting block 501 fixedly connected to the outer wall of one end of the positioning block 404. A horizontally arranged pressure plate 502 is rotatably connected to the outside of the mounting block 501. A screw 503 is slidably connected inside the pressure plate 502. The screw 503 is threadedly connected inside the positioning block 404. A fixing structure is provided on the outside of the screw 503.

[0022] The fixing structure includes a push rod 505 rotatably connected to the outside of the screw 503. The inner wall of the top of the push rod 505 is in contact with the outer wall of the top of the pressure plate 502. A limiting groove 506 is opened on the outer wall of the top of the positioning block 404. A pressing block 507 adapted to the push rod 505 is slidably connected inside the limiting groove 506. The pressing block 507 is located on one side of one of the limiting rods 403.

[0023] Pushing the movable end of the pressure plate 502 causes it to fit against the outer wall of the positioning block 404, thus clamping and fixing the cable. Then, twisting the screw 503 causes it to rotate into the positioning block 404. Since the push rod 505 is in contact with the top wall of the pressure plate 502, its rotational freedom is restricted, and it can only move axially. It will be driven forward by the screw 503. The push rod 505 then contacts the inclined surface of the extrusion block 507, and the push rod 505 can push the extrusion block 507 along the limiting groove 506 toward the limiting rod 403. The static friction between the extrusion block 507 and the limiting rod 403 is greatly increased, ensuring that the cable will not move downward due to gravity, making the cable more stable.

[0024] like Figure 3 As shown, a rubber pad 504 is fixedly connected to the outer wall of each end of the pressure plate 502 that is close to each other, which can further improve the friction between the cable and the pressure plate 502 and will not cause damage to the cable.

[0025] like Figure 4 As shown, the connecting component 6 includes a plug strip 602 fixedly connected to the bottom outer wall of the vertical frame 401, and a limiting groove 601 adapted to the plug strip 602 is provided on the top outer wall of the vertical frame 401.

[0026] If the height of the cabinet 1 to be installed is much greater than the length of the vertical frame 401, another vertical frame 401 can be picked up and connected to it using the connecting component 6. Align the plug strip 602 at the bottom of the new vertical frame 401 with the limiting groove 601 at the top of the original vertical frame 401, and then connect the two. At this time, the two vertical frames 401 will be connected into a whole and can only be pulled horizontally to disassemble. After the vertical frame 401 is fixed inside the cabinet 1, the top vertical frame 401 will be completely restricted and the state will be stable enough. The selection principle of the horizontal frame 402 is the same as above. If the length is insufficient, extension bolts can be used for connection and reinforcement.

[0027] like Figure 2 and Figure 4 As shown, two connecting pieces 3 are fixedly connected to the bottom outer wall of the vertical frame 401 and the outer wall of one side of the two horizontal frames 402.

[0028] The vertical frame 401 and the horizontal frame 402 are connected to the cabinet 1 by bolts passing through the through holes of the connecting piece 3, so that the mechanism is stable enough.

[0029] This utility model provides a cable positioning mechanism for the inside of a power cabinet, the specific working principle of which is as follows: When the device is working, if the height of the cabinet 1 to be installed is much greater than the length of the vertical frame 401, another vertical frame 401 can be picked up and connected to the other using the connecting component 6. Align the plug strip 602 at the bottom of the new vertical frame 401 with the limiting groove 601 at the top of the original vertical frame 401, and then connect the two. At this time, the two vertical frames 401 will be connected into a whole and can only be pulled horizontally to disassemble. After the vertical frame 401 is fixed inside the cabinet 1, the top vertical frame 401 will be completely restricted and the state will be stable enough. The selection principle of the horizontal frame 402 is the same as above. If the length is insufficient, it can be reinforced by using extension bolts.

[0030] The horizontal frame 402 and the vertical frame 401 are connected and fixed using connectors. The horizontal frame 402 should be located below the electrical component mounting plate 2. Finally, the vertical frame 401 and the horizontal frame 402 are connected to the cabinet 1 by bolts passing through the through holes of the connecting piece 3, so that the mechanism is stable enough.

[0031] The external cables are passed through cabinet 1 and arranged side by side outside positioning block 404. Then, they are aligned with the grooves outside positioning block 404. The cable arrangement principle is shown in the figure. Cables connecting to components closer to the bottom are placed on the inside, and cables connecting to components higher up are placed on the outside. When the cable reaches the position to be connected, it is bent laterally to bring it close to the horizontal frame 402. Then, it is placed into the groove outside positioning block 405. With the support of the vertical frame 401 and the horizontal frame 402, the cables can maintain a neat arrangement, which can greatly shorten the troubleshooting time. Maintenance personnel can access the target circuit without disassembling a large number of cables. It can also avoid the interference of electrical signals caused by tangled cables. Finally, the cables are fixed with the binding component 5, so that the cables cannot become loose.

[0032] Pushing the movable end of the pressure plate 502 causes it to fit against the outer wall of the positioning block 404, thus clamping and fixing the cable. Then, twisting the screw 503 causes it to rotate into the positioning block 404. Since the push rod 505 is in contact with the top wall of the pressure plate 502, its rotational freedom is restricted, and it can only move axially. It will be driven forward by the screw 503. The push rod 505 then contacts the inclined surface of the extrusion block 507, and the push rod 505 can push the extrusion block 507 along the limiting groove 506 toward the limiting rod 403. The static friction between the extrusion block 507 and the limiting rod 403 is greatly increased, ensuring that the cable will not move downward due to gravity, making the cable more stable.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
