Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, specifically a layered wiring slot device for a power distribution cabinet. Background Technology

[0002] Distribution cabinets are key equipment in power systems for power distribution, control, and protection. They contain a large number of power cables, control cables, and signal cables. Traditionally, distribution cabinet wiring often involves directly bundling cables to the cabinet frame with cable ties or using simple cable trays for rough organization.

[0003] This wiring method has many drawbacks. The cables are mixed together, which is not conducive to heat dissipation and poses a safety hazard. Secondly, when it is necessary to repair or replace a cable, a large number of cable ties must be untied, which is cumbersome and can easily interfere with other cables. Existing technology uses some card slots to bundle the cables and sets card protrusions in the card slots to stabilize the cables. However, in actual use, the fixing effect of the card protrusions is not good. Although the fixing methods of cable ties and clamps are stable, they are troublesome to disassemble and have certain shortcomings.

[0004] Therefore, this application provides a layered wiring slot device for a power distribution cabinet to solve the above problems. Utility Model Content

[0005] This application provides a layered wiring card slot device for power distribution cabinets, which aims to solve the problems mentioned in the background art, such as the difficulty in disassembling existing card slot plates when fixing cables.

[0006] To achieve the above objectives, this application provides the following technical solution: a layered wiring slot device for a power distribution cabinet, comprising a back plate, multiple mounting slots formed on the back plate, and clamping units disposed on the mounting slots for clamping cables. The mounting channels are arranged along the length of the back plate, and several mounting channels are arranged in layers along the width of the back plate. The snap-fit ​​unit includes a support block disposed on the mounting channel. The support block has a plurality of first snap-fit ​​slots arranged in a linear array. One end of the support block has a sliding groove along the end of the first snap-fit ​​slot. A push-pull strip is slidably installed in the sliding groove. A plurality of stop bars arranged in a linear array are fixedly installed on the push-pull strip. The stop bars have an L-shaped structure and are adapted to the first snap-fit ​​slots. In this way, during cable routing, the backplate is installed inside the distribution cabinet, and then the support block is snapped into the corresponding mounting groove. Then, the push-pull bar is pulled, which moves the stop bar in the slide groove, causing the stop bar to misalign with the end of the first slot, thus opening the end of the first slot. The cable is then inserted into the first slot. Subsequently, the push-pull bar is pushed in the opposite direction, causing the push-pull bar to move in the slide groove, so that the stop bar moves again from the side of the cable to the end of the slide groove. The L-shaped structure, together with the first slot, forms a closed frame, fixing the cable in the first slot, thus completing the quick fixing of the cable. During maintenance, simply pulling the push-pull bar is enough to open or close the end of the first slot, which is convenient and efficient.

[0007] Preferably, in order to stabilize the cable, the first slot is U-shaped, and the two opposite surfaces of the inner sidewall of the first slot are fixedly installed with protrusions to further tighten the cable in the first slot and improve stability.

[0008] Preferably, for ease of operation, the push-pull strip and the slide groove are interference-fitted, and the push-pull strip and the outer wall of the slide groove are friction-fitted. One end of the push-pull strip is fixedly installed with a push-pull block with a cross-sectional area larger than that of the slide groove. The position of the push-pull strip can be changed by pulling the push-pull block, which is convenient and quick.

[0009] Preferably, in order to fix the back plate, several fixing holes are provided on the outer side wall of the back plate along the edge position, and bolts are used to fix it through the fixing holes, which is convenient and quick.

[0010] Preferably, for quick installation, the support block is detachably connected to the back plate. Two symmetrically distributed L-shaped locking strips are fixedly installed on the outer wall of the support block. The locking strips are flexible and are engaged in the installation groove. The support block is slidably connected to the installation groove to adjust the installation displacement, adapt to the cable position, and improve adjustability.

[0011] Preferably, in order to guide the cable, the slot device further includes a guide mechanism for guiding the cable routing. The guide mechanism includes several guide blocks disposed on the back plate. The guide blocks are disposed between two adjacent mounting slots. Several second slots are arranged in a linear array on the guide blocks. The second slots are U-shaped to support the cable and further improve the stability of the cable.

[0012] Preferably, for quick installation, the guide block is detachably connected to the back plate. The back plate has several locking holes. A rubber post is fixedly installed on the outer wall of the guide block. The rubber post is inserted into the locking hole. The diameter of the rubber post is larger than the diameter of the locking hole, which completes the quick installation and facilitates disassembly and use.

[0013] This cable tray device involves installing a backplate inside the distribution cabinet, then snapping a support block into the corresponding mounting groove. Pulling the push-pull bar causes the stop bar to move within the slide groove, misaligning it with the end of the first cable tray and opening the end of the first cable tray. The cable is then inserted into the first cable tray. Subsequently, pushing the push-pull bar in the opposite direction causes the stop bar to move within the slide groove, moving it again from the side of the cable to the end of the slide groove. The L-shaped structure, in conjunction with the first cable tray, forms a closed frame, securing the cable within the first cable tray for rapid cable fixation. During maintenance, simply pulling the push-pull bar opens or closes the end of the first cable tray, making it convenient and efficient.

[0014] When the cable needs to be bent and guided by the guide block, the rubber post on the guide block is aligned with the locking hole on the back plate. The guide block is pressed down, and the rubber post is squeezed into the locking hole, thereby locking the guide block on the back plate. This completes the quick installation and is easy to disassemble and use. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Example 1 This embodiment provides a layered wiring slot device for a power distribution cabinet, such as... Figure 1-9 As shown, the slot device includes a back plate 1, multiple mounting slots 2 formed on the back plate 1, and a clamping unit 3 disposed on the mounting slots 2 for clamping cables. The mounting channel 2 is arranged along the length of the back plate 1, and several mounting channels 2 are arranged in layers along the width of the back plate 1. The snap-fit ​​unit 3 includes a support block 31 disposed on the mounting channel 2. The support block 31 has a plurality of first snap-fit ​​slots 32 arranged in a linear array. One end of the support block 31 has a sliding groove 33 along the end of the first snap-fit ​​slot 32. A push-pull strip 34 is slidably installed in the sliding groove 33. A plurality of baffles 35 arranged in a linear array are fixedly installed on the push-pull strip 34. The baffles 35 have an L-shaped structure and are adapted to the first snap-fit ​​slots 32.

[0019] In use, the backplate 1 is installed inside the distribution cabinet, and then the support block 31 is snapped into the corresponding mounting groove 2. Then, the push-pull strip 34 is pulled, and the push-pull strip 34 drives the stop strip 35 to move in the slide groove 33, so that the stop strip 35 is misaligned with the end of the first slot 32, making the end of the first slot 32 open. Then, the cable is inserted into the first slot 32. Then, the push-pull strip 34 is pushed in the opposite direction, and the push-pull strip 34 drives the stop strip 35 to move in the slide groove 33, so that the stop strip 35 moves again from the side of the cable to the end of the slide groove 33. The L-shaped structure and the first slot 32 form a closed frame, fixing the cable in the first slot 32, completing the quick fixing of the cable. During maintenance, simply pull the push-pull strip 34 to open or close the end of the first slot 32, which is convenient and efficient.

[0020] Specifically, the first slot 32 is U-shaped, and the two opposite surfaces of the inner sidewall of the first slot 32 are fixedly installed with the protrusions 321.

[0021] When the cable is inserted into the first slot 32, the cable sheath is squeezed by the protrusion 321, which further tightens the cable in the first slot 32 and improves stability.

[0022] More specifically, the push-pull strip 34 and the slide groove 33 are interference-fitted, the outer wall surface of the push-pull strip 34 and the slide groove 33 are friction-fitted, and a push-pull block 36 with a cross-sectional area larger than that of the slide groove 33 is fixedly installed at one end of the push-pull strip 34.

[0023] In use, the stability of the push-pull strip 34 is improved by increasing the friction force, which prevents the push-pull strip 34 from detaching from the slide groove 33 at will. When operating the push-pull strip 34, the position of the push-pull strip 34 can be changed by pulling the push-pull block 36, which is convenient and quick.

[0024] Furthermore, several fixing holes 11 are provided on the outer side wall of the back plate 1 along the edge.

[0025] When in use, install the back plate 1 inside the distribution cabinet, align the fixing holes 11 on the back plate 1 with the reserved holes on the distribution cabinet, and then fix it by passing bolts through the fixing holes 11, which is convenient and quick.

[0026] Furthermore, the support block 31 is detachably connected to the back plate 1. Two symmetrically distributed L-shaped locking strips 37 are fixedly installed on the outer wall of the support block 31. The locking strips 37 are flexible structures and are engaged in the mounting groove 2. The support block 31 is slidably connected to the mounting groove 2.

[0027] In use, squeeze the two retaining strips 37 to reduce the gap between them. Then, align the retaining strips 37 on the support block 31 with the mounting channel 2 and press down on the support block 31 so that the retaining strips 37 are squeezed into the mounting channel 2. When the retaining strips 37 lose pressure, they spring back and lock into the mounting channel 2. Then, push the support block 31 along the mounting channel 2 to adjust the installation displacement, adapt to the cable position, and improve adjustability.

[0028] Example 2 Unlike Embodiment 1, after the line is fixed, it is usually necessary to bend and guide the line. For this purpose, the slot device also includes a guide mechanism 4 for guiding the cable routing. The guide mechanism 4 includes a number of guide blocks 41 disposed on the back plate 1. The guide blocks 41 are disposed between two adjacent mounting channels 2. A number of second slots 42 distributed in a linear array are opened on the guide blocks 41. The second slots 42 are U-shaped.

[0029] In use, after fixing the line, install the guide block 41 on the back plate 1. After installing the cable, bend the cable and put it into the second slot 42 on the guide block 41 to support the cable and further improve the stability of the cable.

[0030] Furthermore, the guide block 41 is detachably connected to the back plate 1. The back plate 1 has several locking holes 43. A rubber post 44 is fixedly installed on the outer wall of the guide block 41. The rubber post 44 is inserted into the locking hole 43. The diameter of the rubber post 44 is larger than the diameter of the locking hole 43.

[0031] When using the guide block 41 to bend and guide the cable, align the rubber post 44 on the guide block 41 with the locking hole 43 on the back plate 1, and press down on the guide block 41. The guide block 41 is pressed down and squeezes the rubber post 44 into the locking hole 43, thereby locking the guide block 41 onto the back plate 1, completing the quick installation and facilitating disassembly and use.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
