Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to an electrical power distribution cabinet that facilitates line layout. Background Technology

[0002] Electrical distribution cabinets are devices used for power distribution and protection, widely used in residential, industrial, and commercial fields. Their main function is to distribute, control, and protect power by installing various electrical components (such as circuit breakers, contactors, and relays) to ensure the stable operation of the power system. In traditional technology, the internal wiring of electrical distribution cabinets is usually bundled and secured with cable ties. While this method can temporarily organize the wiring, it presents certain inconveniences in actual use and maintenance. On the one hand, during maintenance, workers need to cut the cable ties, disconnect the wires, and locate the target line one by one, increasing the difficulty and time cost of maintenance. On the other hand, after maintenance, the wiring needs to be bundled again with cable ties, wasting resources and reducing work efficiency. This traditional wiring method cannot meet the requirements of modern electrical distribution systems for efficient management and maintenance.

[0003] Utility model patent CN219739572U discloses a power distribution cabinet that facilitates wiring layout. The cabinet includes a cabinet body with a first mounting plate inside. Below the first mounting plate is a distribution board installed inside the cabinet body. The upper surface of the distribution board has multiple evenly distributed distribution holes. When using this device, various electrical components are installed on the first mounting plate. The distribution holes on the distribution board allow for the arrangement of the electrical component wiring. Simultaneously, through holes and perforations categorize and arrange the wiring within the distribution frame. Multiple partitions further separate the wiring within the distribution frame, resulting in neat wiring arrangement. Other electrical components are sequentially installed on a second mounting plate, and the wiring within the distribution frame is connected to the corresponding electrical components via wiring holes. This facilitates the neat and categorized arrangement of wiring, preventing messy wiring that could cause tangling and damage, and making it easier for maintenance personnel to inspect the wiring.

[0004] While the existing technology can classify and arrange wires through distribution boards, distribution holes, and partitions, resulting in neater wiring and reducing the risk of tangling and damage, some significant drawbacks remain in practical use. First, the cover plate of the distribution frame is connected to the frame using snap-fit ​​and slot connections, which is inconvenient during opening and closing, especially when frequent switching is required, thus affecting operational efficiency. Second, when multiple wires are concentrated within the distribution frame, the heat generated during operation is difficult to dissipate due to the tight connection between the cover plate and the frame, causing the internal temperature of the distribution frame to gradually rise, posing a safety hazard. Therefore, the existing technology still has considerable room for improvement in terms of ease of operation and safety. In view of the above problems, we propose an electrical distribution cabinet that facilitates wiring arrangement, aiming to address the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical distribution cabinet that facilitates circuit layout, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An electrical distribution cabinet for easy wiring layout includes an electrical distribution cabinet body with a cabinet door hinged to the front. A meter mounting plate is located inside the cabinet body near the top, for mounting electrical components such as circuit breakers and contactors. A cable tray is located at the bottom of the meter mounting plate, guiding wires downwards to a junction box through cable outlets and through-holes a. A support plate is located inside the cabinet body near the bottom, supporting meter mounting vertical plates and cable tray assemblies to enhance structural stability. Multiple meter mounting vertical plates are arranged equidistantly between the cable tray and the support plate, for mounting other electrical components. A cable tray assembly is located between adjacent meter mounting vertical plates, for centrally classifying wires. The wiring assembly includes a junction box with an open front side. The junction box uses a sliding groove and a U-shaped fixing block to classify and manage wires.
