Description

Technical Field

[0001] This utility model relates to the field of low-voltage switchgear technology, and in particular to a low-voltage switchgear that facilitates internal wiring management. Background Technology

[0002] Low-voltage switchgear is an electrical device used to control and protect low-voltage power grids. It is widely used in power systems of industrial, commercial and civil buildings. As an important basic component of cable management devices, cable trays are an important part of low-voltage switchgear for managing and protecting wires. They help to arrange and fix the wires neatly, avoiding mess and tangling, while providing mechanical protection to prevent the wires from being damaged.

[0003] After installation and use in a low-voltage switchgear, the capacity of the horizontal cable trays is fixed. However, the number of wires in the horizontal cable trays is relatively large. This is because when wiring adjacent components, the wires often need a certain margin to ensure the flexibility and reliability of the wiring, taking into account the installation layout of the components. These wires with margin are usually temporarily placed in the horizontal cable trays, increasing the number of cables in the horizontal cable trays. In addition, there are many wiring requirements between adjacent circuit breakers, contactors and other equipment in the same row, and the number of cables is also large. Therefore, the fixed horizontal cable trays are difficult to adapt to changes in wiring requirements and cannot flexibly cope with different numbers and specifications of cables. When adding or changing lines, it is easy to exceed the capacity of the original cable trays, resulting in the need to replace the entire cable tray or install parallel cable trays, including removing the original cable trays and rearranging the cables, which is time-consuming, labor-intensive and increases the difficulty of construction.

[0004] Therefore, this application provides a low-voltage switchgear that facilitates internal wiring management, in order to solve the problems mentioned in the background art. Utility Model Content

[0037] The present invention will be further explained below with reference to specific embodiments.

[0038] like Figures 1-13 As shown, this embodiment provides a low-voltage switchgear for easy internal cable management, including a cabinet 1, a back panel 2 on the inner side of the cabinet 1, vertical cable management grooves 3 on the two longitudinal edges of the back panel 2, and a plurality of horizontal cable management grooves 4 evenly arranged between the two vertical cable management grooves 3; the body of the horizontal cable management groove 4 is provided with a first base plate 43, the first base plate 43 is slidably connected to a second base plate 44, and the outer edges of the first base plate 43 and the second base plate 44 are provided with vertical long side plates 41, the two ends of the long side plates 41 are respectively connected to short side plates 35, and the bottom of the short side plates 35 is slidably connected to a third base plate 31 in the vertical cable management groove 3. The sliding of the short side plates 35 is used to adjust the opening width of the horizontal cable management groove 4 to accommodate cables of different numbers and diameters. The low-voltage switchgear is slidably connected to the first and second base plates in the horizontal cable tray. With the short side plate sliding along the slide bar in the vertical cable tray, the opening width of the horizontal cable tray can be flexibly adjusted to adapt to changes in wiring requirements. This avoids the tedious process of removing the original cable tray and rearranging the cables, saving construction time and labor costs.

[0039] like Figures 2-8As shown, in this embodiment, the vertical cable management trough 3 includes a third base plate 31. A vertical third side plate 32 is provided on the outer edge of the third base plate 31. Multiple sets of short side plates 35 are slidably connected to the inner edge of the third base plate 31. Adjustment gaps 36 are provided between the multiple sets of short side plates 35 to provide adjustment space, allowing the opening width of the horizontal cable management trough 4 to be flexibly adjusted according to the actual number and diameter of cables, meeting different wiring requirements and adapting to diverse scenarios of component layout and wiring within low-voltage switchgear, thus improving the adaptability and flexibility of the cable management system. Each set of short side plates 35 includes an adjacent first short side plate 351 and a second short side plate 352.

The combination of the multiple positioning holes 38 on the sliding bar 33 and the wing screw 39 on the outer side of the square groove 34 achieves quick fixation of the slid-out short side plate 35, simplifying operation, improving work efficiency, and ensuring stability after adjustment.

[0040] like Figures 8-13As shown, in this embodiment, the second base plate 44 includes a first sliding plate 441. The first sliding plate 441 and the first base plate 43 are symmetrically arranged.

The two ends of the upper side plate 411 and the lower side plate 412 are respectively provided with second snap-fit ​​grooves 413. The second snap-fit ​​grooves 413 are adapted to be fitted with T-shaped blocks 353 to facilitate the installation between the vertical cable management groove 3 and the horizontal cable management groove 4. The edges on both sides of the upper surface of the first base plate 43 are provided with inverted L-shaped parts 46. The inverted L-shaped parts 46 and the first base plate 43 together form a first snap-fit ​​groove 45. The first snap-fit ​​groove 45 is adapted to be fitted with the two ends of the second sliding plate 442. The outlet end of the first snap-fit ​​groove 45 is provided with a snap-fit ​​plate 451. Vertical limiting blocks 47 are provided at the two top corners of the upper surface of the second sliding plate 442. The limiting blocks 47 slide to abut against the snap plate 451 to restrict the second sliding plate 442 from continuing to slide and prevent it from sliding out of the first snap groove 45. The width of the adjustment gap 36 is 1-2mm larger than the sliding stroke of the limiting block 47. The width of the adjustment gap 36 is slightly larger than the sliding stroke of the limiting block 47, providing the necessary space margin for the sliding operation.

[0041] like Figure 4 , Figure 8 As shown, in this embodiment, a plurality of elongated holes 48 are evenly arranged on the first base plate 43 near the upper side plate 411. The elongated holes 48 are fixed to the back plate 2 by bolts. A plurality of mounting holes 37 are provided on the third base plate 31. The mounting holes 37 are engaged with the corresponding holes on the back plate 2 by bolts to fix the third base plate 31 to the back plate 2, which is used to fix the vertical cable management groove 3 and the horizontal cable management groove 4 to the back plate 2.

[0042] This utility model also provides a working principle for a low-voltage switchgear that facilitates internal cable management: When in use, the vertical cable management trough 3 and the horizontal cable management trough 4 are fixed on the back plate 2. When the user's wiring requirements change, the wing screw 39 is rotated out of the positioning hole 38, and the second short side plate 352 is moved, so that the second sliding plate 442 in the horizontal cable management trough 4 slides along the first snap-fit ​​groove 45, driving the lower side plate 412 to move synchronously, increasing the distance between the upper side plate 411 and the lower side plate 412 in the horizontal cable management trough 4, and increasing the opening width of the horizontal cable management trough 4 to adapt to changes in wiring requirements, avoiding the tedious process of removing the original cable trough and rearranging the cables, saving construction time and labor costs. Finally, the wing screw 39 is inserted into the corresponding positioning hole 38 to fix the second short side plate 352 after the position adjustment.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
