Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet wiring technology, specifically to a modular layered wiring structure for electrical cabinets. Background Technology

[0002] Electrical cabinets are made of steel and are used to protect components and ensure their proper functioning. The materials used in electrical cabinet manufacturing are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are more flexible than hot-rolled steel plates and are more suitable for electrical cabinet manufacturing. Electrical cabinets have a wide range of applications, mainly in the chemical industry, environmental protection industry, power systems, metallurgical systems, industrial sectors, nuclear power industry, fire safety monitoring, transportation industry, etc. They are primarily used to install residual current devices (RCDs), circuit breakers, and other power distribution equipment.

[0003] A search revealed patent application CN202420531563.2, which discloses a modular power distribution cabinet wiring structure. The structure includes a modular power distribution cabinet with a wiring box fixedly connected to its inner wall. The wiring box has round holes on both its front and rear sides, with seven round holes on each side. A wiring conduit fits snugly onto the upper surface of the wiring box, and round hole blocks are symmetrically fixedly connected to the side walls of the wiring conduit. These round hole blocks are bolted to the inner wall of the modular power distribution cabinet. A long, narrow wiring box is located at the bottom of the wiring conduit, and the parallel arrangement of wiring conduits allows for the classification of wiring. Gaps between the wiring boxes and conduits facilitate viewing the wiring within the conduits, enabling quick identification and location when needed, thus maintaining a neat wiring layout. This orderly wiring layout improves the stability and safety of the power distribution cabinet.

[0004] However, this patent has its shortcomings. In actual use, this wiring structure requires workers to insert the connecting wires into the wiring conduit through the pre-drilled holes, then exit the conduit from the bottom, and then insert them into the wiring box 2. Finally, the wires exit through the pre-drilled holes in the wiring box 2. The wiring process is cumbersome, time-consuming, and difficult, resulting in low wiring efficiency. As the number of connecting wires in the conduit and wiring box increases, wire jamming can easily occur during subsequent wiring, preventing the connecting wires from being pulled out smoothly.

[0005] To address this, we propose a modular, layered wiring structure for electrical cabinets. Utility Model Content

[0006] The purpose of this utility model is to provide a modular layered wiring structure for electrical cabinets to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular layered wiring structure for an electrical cabinet, comprising a cabinet body, two uprights fixedly installed inside the cabinet body, and multiple L-shaped frames fixedly installed sequentially from top to bottom inside the two uprights. Each L-shaped frame has multiple cable slots at its bottom end. Multiple cable distribution slots are provided inside the two uprights. T-shaped slots are provided at the front ends of the two uprights. Cover plates are inserted into the two T-shaped slots. Two damping shafts are rotatably connected to the rear of the cover plate on each upright. The ends of the two damping shafts near the L-shaped frames extend beyond the uprights and are fixedly fitted with baffles. The ends of the two baffles away from the L-shaped frames abut against the cover plate. Through holes are provided at the rear bottom ends of the multiple cable distribution slots.

[0008] Optionally, a lever is fixedly installed at the front end of each of the two cover plates, which facilitates pulling the cover plates.

[0009] Optionally, each of the L-shaped frames has multiple mounting slots at its rear end, which facilitates the installation of power distribution equipment on the L-shaped frame using external bolts and nuts.

[0010] Optionally, both of the covers are made of transparent acrylic sheet material, which makes it easier for staff to see the wiring through the covers.

[0011] Optionally, the front end of the cabinet is connected to a cabinet door via a hinge, which facilitates the installation and removal of electrical equipment such as residual current devices and circuit breakers by opening the cabinet door.

[0012] Optionally, the cabinet door is provided with multiple viewing windows, which facilitate the viewing of the working status of the electrical equipment inside the cabinet.

[0013] Optionally, a back panel is fixedly installed at the rear end of the cabinet by multiple bolts, and an opening is reserved at multiple through holes on the back panel to facilitate the extension of cables out of the cabinet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Through the cooperation of cable trays, stands, covers, T-slots, damping shafts, baffles, branch channels, and through holes, connecting wires can be directly clipped into the branch channels and cable trays during the wiring process, making wiring installation more convenient and faster, thereby further improving the efficiency of wiring work. At the same time, the transparent cover not only protects the connecting wires, but also makes it easier for staff to find aging or damaged lines, which is beneficial for subsequent maintenance and use.
