Description

Technical Field

[0001] This utility model belongs to the field of power distribution cabinet technology, and specifically relates to a power distribution cabinet adapter. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits, while motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit from the previous-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Traditional wiring methods for distribution cabinets typically use fixed cable trays or cable ties, which present the following problems in practical use: 1. Scattered and difficult-to-organize wires: Due to the lack of layered restraint for wires of different heights, they easily cross and tangle inside the cabinet, affecting aesthetics and potentially causing insulation damage due to friction, increasing the risk of short circuits. 2. Poor flexibility of the fixing structure: Existing wire bundling devices are mostly rigid designs, unable to adjust their height or angle according to the wire routing, leading to repeated disassembly or re-fixing during wiring, reducing work efficiency. 3. Inconvenient installation and maintenance: Traditional wire bundling methods often require fixing a support structure before wire pulling, affecting the smoothness of wiring. Utility Model Content

[0004] The purpose of this invention is to provide a power distribution cabinet transfer cable device to solve the problems of wire dispersion and cable management in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power distribution cabinet transfer cable device includes wires inside the cabinet entering a control box through a wire hole. A wire bundling device is located around the wire hole. The wire bundling device consists of a first wire bundling assembly and a second wire bundling assembly. The height of the first wire bundling assembly is higher than that of the second wire bundling assembly. Both are used to bind wires that are dispersed at different heights.

[0007] Both the first and second wire harness assemblies include a fixing block, a support rod, and a wire harness plate. Several fixing blocks are evenly distributed around the wire holes. The support rod is disposed inside the fixing block, and a wire harness plate for harnessing the wires is provided on the top of the support rod.

[0008] Preferably, the cable tray is integrally molded from a tough material. The tough material can be either plastic or metal, both of which are good choices for toughness.

[0009] Preferably, four fixing blocks are equidistantly distributed around the wire hole, the opening of the wire harness plate faces the wire hole, and the first wire harness assembly and the second wire harness assembly are symmetrically installed on the fixing blocks.

[0010] Preferably, the bottom of the support rod is equipped with a movable wheel, and positioning shafts are fixed on both sides of the movable wheel. The movable wheel is rotatably connected to the bottom of the support rod through the positioning shafts. The fixed block is provided with a sliding groove for the movable wheel to roll. Positioning grooves that cooperate with the positioning shafts are opened on both sides of the sliding groove. An installation groove for the positioning shaft to be inserted and installed is opened on one side of the positioning groove.

[0011] Preferably, the tail end of the cable tray is connected to the top of the support rod, and the cable tray has arc-shaped arms on both sides, with guide heads inclined inward at the tail ends of the arc-shaped arms.

[0012] Preferably, the guide heads at both ends are initially in contact with each other. They will only separate when the wire enters the cable tray from the guide heads, or when the arc-shaped arm is pried open by force.

[0013] Preferably, the cable tie plate has a reinforcing rib at its inner end. The reinforcing rib is used to increase the strength of the cable tie plate and prevent it from exceeding its deformation range due to excessive tension.

[0014] Preferably, the arc-shaped arm has transition cavities. When there are too many wires, a rope can be tied between the two transition cavities, causing the arc-shaped arm to tighten inward, improving the wire-binding function of the cable tray and preventing the wires from being squeezed out of the cable tray. At the same time, the transition cavities can improve the deformation toughness of the arc-shaped arm.

[0015] Preferably, the bottom of the cable tray is provided with a rotating shaft, and the top of the support rod has a cavity for mounting the rotating shaft. With the cooperation of the rotating shaft and the cavity, the cable tray can rotate freely at an angle, optimizing the flexibility of the overall product.

[0016] The technical solution of this utility model has the following beneficial effects:

[0017] 1. The first and second wire bundle assemblies bind wires that are scattered at different heights, thus binding the wires from bottom to top. When the first and second wire bundle assemblies are used together, the dispersion of the wires can be greatly reduced, making it easier for staff to organize the wires entering the control box.

[0018] 2. The movable support rod, with its rotating angle, allows for adjustment of the cable management height difference within the cable tray. The tilted support rod also facilitates subsequent disassembly under stress. The entire system employs a detachable connection method, significantly improving component replaceability. The support rod and fixing block can be installed after all wires have been pulled, completing the final cable management without affecting the wire pulling process. The cable tray, with its flexible adjustment of displacement and angle, can follow changes in the tilt angle of the wires without affecting overall usability. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0036] Example 1:

[0037] refer to Figures 1-9 A power distribution cabinet transfer cable device includes a wire 60 inside the cabinet 10 entering the control box 20 through a wire hole 201. A wire bundling device is located around the wire hole 201. The wire bundling device consists of a first wire bundling assembly 202 and a second wire bundling assembly 203. The height of the first wire bundling assembly 202 is higher than that of the second wire bundling assembly 203. Both are used to bind the wires 60 that are dispersed at different heights.

[0038] The wires that pass through the wire hole 201 into the control box 20 are used to connect the electrical control components, sensing components, etc. inside the control box 20. The multiple wires 60 in the wire hole 201 are more separated as they approach the top. Therefore, the first wire bundle assembly 202 and the second wire bundle assembly 203 bind the wires 60 that are dispersed at different heights. This can bind the wires 60 from bottom to top. With the combined use of the first wire bundle assembly 202 and the second wire bundle assembly 203, the dispersion of the wires 60 can be greatly reduced, making it easier for staff to organize the wires 60 that have entered the control box 20.

[0039] Secondly, an alternative solution is to choose either the first wire harness assembly 202 or the second wire harness assembly 203 for independent wire harnessing. When the wire 60 is pulled from the wire hole 201 to connect to the electronic control element, and the distance between the wire 60 and the electronic control element is not very long, only one wire harness assembly can be installed. This can also help to bind and concentrate the short-distance dispersed wires 60.

[0040] refer to Figures 3-9 The first wire harness assembly 202 and the second wire harness assembly 203 both include a fixing block 30, a support rod 40, and a wire harness plate 50. The fixing blocks 30 are evenly distributed around the wire hole 201. The support rod 40 is set inside the fixing block 30. The top of the support rod 40 is provided with a wire harness plate 50 for harnessing wires.

[0041] Four fixing blocks 30 are evenly distributed around the wire hole 201. The opening of the wire harness plate 50 faces the wire hole 201. The first wire harness assembly 202 and the second wire harness assembly 203 are symmetrically installed on the fixing blocks 30. The symmetrical installation of the first wire harness assembly 202 and the second wire harness assembly 203 can make the orientation of the wire harness plate 50 consistent, forming mutual directional constraints and preventing the wires 60 from detaching and dispersing from the wire harness plate 50.

[0042] refer to Figure 3 , Figure 7 and Figure 8 The bottom of the support rod 40 is equipped with a movable wheel 401, and the movable wheel 401 is fixed with a positioning shaft 402 on both sides. The movable wheel 401 is rotatably connected to the bottom of the support rod 40 through the positioning shaft 402. The fixed block 30 is provided with a sliding groove 301 for the movable wheel 401 to roll. The sliding groove 301 is provided with positioning grooves 303 on both sides to cooperate with the positioning shaft 402. The upper side of one side of the positioning groove 303 is provided with an installation groove 302 for the positioning shaft 402 to be inserted and installed.

[0043] In the above scheme, the support rod 40 has two intersecting branches at its bottom, which are rotatably connected to the positioning shafts 402 on both sides of the movable wheel 401. Installation of the support rod 40 requires inserting the positioning shafts 402 into the mounting groove 302 and into the positioning groove 303. Simultaneously, the movable wheel 401 will contact the ground of the sliding groove 301, allowing the support rod 40 to move freely within the fixed block 30. Similarly, the support rod 40 is rotatably connected to the movable wheel 401. Therefore, (refer to...) Figure 3 (In the direction of the arrow), the support rod 40 can rotate in the direction of the arrow or in the opposite direction. This allows the support rod 40 to be tilted away from the wire hole 201 when pulling the wire 60 from inside, facilitating the pulling of the wire 60. After all the wires 60 have been pulled, the angle of the support rod 40 can be rotated back, allowing the wires 60 to enter the cable management plate 50. The movable support rod 40, combined with its angle rotation, allows adjustment of the cable management height difference within the cable management plate 50, and the tilted angle of the support rod 40 facilitates subsequent disassembly under stress. The entire system uses a detachable connection method, significantly improving the replaceability of parts. The support rod 40 can be installed with the fixing block 30 after all the wires 60 have been pulled, completing the final cable management without affecting the pulling of the wires 60. The cable management plate 50, with its flexible adjustment of displacement and angle, can follow the tilt angle changes of the wires 60 without affecting the overall use.

[0044] refer to Figure 9 The tail end of the cable tray 50 is connected to the top of the support rod 40. The cable tray 50 has arc-shaped arms 501 on both sides, and the tail end of the arc-shaped arms 501 is inclined inward and has a guide head 502.

[0045] In the above scheme, the arc-shaped arms 501 at both ends of the cable tray 50 can greatly increase the number of cables. The inwardly inclined guide head 502 can facilitate the wires 60 to enter the cable tray 50 from outside the cable tray 50. The inwardly inclined guide head 502 can also restrict the wires 60 inside the cable tray 50, making it difficult for them to detach from the opening end of the cable tray 50.

[0046] Preferably, referring to Figure 9, the guide heads 502 at both ends are initially in contact with each other. They will only separate when the wire 60 enters the cable tray 50 from the guide head 502, or when the arc arm 501 is pried open by force.

[0047] The cable tray 50 has a reinforcing rib 504 at its inner end. The reinforcing rib 504 is used to improve the strength of the cable tray 50 and prevent it from exceeding the deformation range due to excessive tension.

[0048] The cable tray 50 is integrally molded from a tough material; the tough material can be either plastic or metal, both of which are good choices for tough materials.

[0049] Example 2:

[0050] refer to Figure 9 The arc-shaped arm 501 has a transition cavity 503. When there are too many wires 60, a rope can be tied between the two transition cavities 503 to tighten the arc-shaped arm 501 inward, improve the wire-binding function of the wire-binding plate 50, and prevent the wires 60 from being squeezed out of the wire-binding plate 50. At the same time, the transition cavity 503 can improve the deformation toughness of the arc-shaped arm 501.

[0051] Example 3:

[0052] refer to Figure 10 The bottom of the cable tray 50 is provided with a rotating shaft 505, and the top of the support rod 40 has a shaft cavity 403 for mounting the rotating shaft 505.

[0053] In the above solution, with the cooperation of the rotating shaft 505 and the shaft cavity 403, the cable tray 50 can rotate freely at an angle, optimizing the flexibility of the overall product.

[0054] The specific implementation process of this utility model is as follows:

[0055] The installation of the support rod 40 requires inserting the positioning shaft 402 into the mounting slot 302 and ensuring that the positioning shaft 402 enters the positioning slot 303. Simultaneously, the movable wheel 401 will contact the ground of the sliding groove 301, allowing the support rod 40 to move freely within the fixed block 30. The support rod 40 is rotatably connected to the movable wheel 401, from which it can be concluded (refer to...) Figure 3(In the direction of the arrow), the support rod 40 can rotate in the direction of the arrow or in the opposite direction. When pulling the wire 60 from inside the wire hole 201, the support rod 40 can be tilted in the direction of the wire hole 201 to facilitate the pulling of the wire 60. Finally, after all the wires 60 have been pulled, the angle of the support rod 40 is rotated back so that the wires 60 enter the cable tray 50. The movable support rod 40, combined with the angle rotation of the support rod 40, can adjust the height difference of the cable tray 50.

[0056] The above embodiments are merely exemplary models of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection.
