Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet wiring technology, specifically to an internal wiring assembly for a power distribution cabinet. Background Technology

[0002] Distribution cabinet cabling is a core aspect of electrical installation and equipment manufacturing, directly impacting system safety, reliability, and maintainability. Proper cabling not only reduces failure rates but also significantly improves future maintenance efficiency.

[0003] During the wiring process, all wires should be laid out according to the design drawings, keeping them horizontal and vertical, and avoiding crossing and confusion. For distribution cabinets with a lot of internal wiring, the wires often need to be bundled and stacked for fixation. Although this can keep the wiring neatly arranged in rows, the gaps between adjacent wires are small after stacking, making air circulation relatively difficult. This can lead to poor internal heat dissipation and pose certain safety risks. Utility Model Content

[0004] The purpose of this utility model is to provide an internal wiring assembly for a power distribution cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a fixed frame and a mounting frame, the fixed frame being fixed on both sides inside the distribution cabinet, the mounting frame being slidably connected to the front side of the fixed frame, a fixing component being provided between the mounting frame and the fixed frame, and three rows of cable trays being fixed between the fixed frames and located on the rear side of the mounting frame, with cable clamps fixed at equal intervals on the back of each cable tray.

[0006] Preferably, the three rows of ribbon cable boards are staggered, and the spacing between each row of ribbon cable boards is the same. Each layer of ribbon cable boards is composed of multiple independent ribbon cable boards arranged in a straight line from top to bottom.

[0007] Preferably, the fixing frame has an air cavity, and the inner sidewall of the air cavity has air holes.

[0008] Preferably, the fixing component includes a sliding groove and a threaded column. The sliding groove is formed at the front end of the fixing frame, and a sliding block is slidably connected in the sliding groove. The front end of the sliding block is fixedly connected to the threaded column, and the end of the threaded column extends out of the mounting frame and is threadedly connected to an internal threaded sleeve.

[0009] Preferably, a positioning hole is provided on the front side of the mounting bracket and at a position corresponding to the threaded post, and the end of the internal threaded sleeve is located in the positioning hole.

[0010] Preferably, the sliding groove has a T-shaped structure, and the sliding block is a matching T-shaped block.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting three rows of ribbon cable boards on the rear side of the mounting bracket, the cables can be arranged on different ribbon cable boards to achieve the purpose of layering, avoid excessive stacking of cables, increase air circulation between the cable bundles, and thus better dissipate heat.

[0016] 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.

[0017] Please see Figure 1-3 This utility model provides a technical solution: including a fixing frame 1 and a mounting frame 2. The fixing frame 1 is fixed on both sides inside the power distribution cabinet. The mounting frame 2 is slidably connected to the front side of the fixing frame 1. A fixing component 4 is provided between the mounting frame 2 and the fixing frame 1. Three rows of cable trays 3 are fixed between the fixing frames 1 and on the rear side of the mounting frame 2. Cable clips 31 are fixed at equal intervals on the back of each cable tray 3. The three rows of cable trays 3 are staggered and the spacing between each row of cable trays 3 is the same. Each layer of cable trays 3 is composed of multiple independent cable trays 3 arranged vertically in a straight line. An air cavity 11 is opened in the fixing frame 1. An air hole 12 is opened on the inner side wall of the air cavity 11.

[0018] The fixing component 4 includes a sliding groove 41 and a threaded post 44. The sliding groove 41 is opened at the front end of the fixing frame 1. A sliding block 42 is slidably connected in the sliding groove 41. The front end of the sliding block 42 is fixedly connected to the threaded post 44. The end of the threaded post 44 extends out of the mounting frame 2 and is threadedly connected to an internal threaded sleeve 45. A positioning hole 43 is opened on the front side of the mounting frame 2 at a position corresponding to the threaded post 44. The end of the internal threaded sleeve 45 is located in the positioning hole 43. The sliding groove 41 has a T-shaped structure, and the sliding block 42 is a matching T-shaped block.

[0019] Working principle: First, fix the mounting bracket 2 to the designated position at the front end of the fixing bracket 1. When wiring, the wires can be passed through from above and then laid from top to bottom on the cable tray 3. The cable clamps 31 are used for fixing. When a single layer of cable tray 3 cannot cover all the wires, multi-layer wiring can be used to distribute the wires on different cable trays 3, ensuring that there are large gaps between the wires, which is conducive to air circulation and facilitates heat dissipation on the surface of the wires. When fixing the mounting bracket 2, it can be fixed and loosened by loosening and locking the internal thread sleeve 45. When loosening, the mounting bracket 2 can be slid to a designated height and adjusted according to actual needs. At the same time, during use, there is gas flow inside the distribution cabinet, and gas flow will also be generated in its air chamber 11. The gas will flow out from the air hole 12, which can reduce the generation of dead air flow angles.
