Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a U-shaped arrangement structure inside the distribution box. Background Technology

[0002] An electrical box, also known as a distribution box or distribution cabinet, is a device used for centralized management and distribution of electricity. It plays a vital role in the power system and is widely used in homes, commercial buildings, industrial facilities, and public infrastructure. The electrical box centrally manages the electricity from the power source (such as the power grid) and distributes it to various electrical terminals or subsystems through internal wiring and switching devices. By setting up multiple circuit branches, each branch can independently supply power to a specific area or device, thereby achieving more refined power control.

[0003] Traditional electrical boxes often have a loose internal layout, with wires, cables, and electrical components arranged haphazardly, resulting in wasted space, especially in small electrical boxes where limited space is not fully utilized. Secondly, the wiring inside the electrical box is usually messy, with cables crisscrossing each other, increasing the difficulty of troubleshooting and maintenance, and also increasing the risk of misoperation. Therefore, we propose a U-shaped internal layout structure for electrical boxes to solve this problem. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes a U-shaped internal layout structure for the electrical box, which more precisely solves the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] The present invention proposes an internal U-shaped arrangement structure for an electrical box, comprising an outer shell, the outer shell being rectangular in shape, and a common transverse partition fixedly installed between the inner walls of the outer shell to divide the internal space of the outer shell into an upper half and a lower half. Support frames 1 are fixedly connected to the inner walls of the left and right sides of the outer shell, and a common support frame 2 is fixedly installed between the inner walls of the front and rear sides of the outer shell. The support frame 2 is U-shaped, and both support frames 1 and 2 are located in the lower half. A U-shaped area is formed between the support frame 1, the outer shell, and the two support frames 2, and the U-shaped area is used to place electrical wires, cables, and electrical control switches.

[0007] Furthermore, the second support frame includes a base frame and two upright plates. Side plates are provided on both the left and right sides of the base frame. The top of the upright plate is fixedly connected to the bottom of the horizontal partition plate, and one side of the upright plate is fixedly connected to the corresponding side plate.

[0008] Furthermore, the top of the upright plate is provided with a flange structure, the top of the flange structure is fixedly connected to the bottom of the horizontal partition by bolts, one side of the upright plate is fixedly connected to the corresponding side plate by bolts, a connecting edge one is fixedly connected to the front side of the upright plate, and two connecting edges two are fixedly connected to the inner wall of the front side of the outer shell. The connecting edge one and the corresponding connecting edge two are both L-shaped and fit together with each other.

[0009] Furthermore, a rectangular hole is provided at the bottom of the base frame, and a base plate is movably engaged in the rectangular hole. The base plate is fixedly connected to the base frame by bolts.

[0010] Furthermore, through holes one are provided on both the left and right sides of the outer shell, and through hole two is provided on the rear side of the outer shell. Through hole one is connected to the corresponding support frame one, and through hole two is connected to the support frame two. Both through hole one and through hole two are closed by cover plates.

[0011] Furthermore, electrical components and connectors are provided in the upper half area, the second support frame, and the two first support frames. Two through holes are opened on the front side of the outer shell, and a door panel is provided in the through hole three. A rotary lock is provided on the door panel.

[0012] Furthermore, multiple holes are provided on one side of the second support frame, and multiple sleeves are fixedly installed on one side of the second support frame. The holes and sleeves are used to support the connection of wires and cables with electrical components.

[0013] Furthermore, a right-angle notch is provided on the bottom rear side of the outer shell, the right-angle notch is connected to the outer shell, the right-angle notch is located below the second support frame, and the same vertical partition is fixedly installed between the bottom inner wall of the outer shell and the bottom of the second support frame.

[0014] The beneficial effects of this utility model are as follows:

[0015] The U-shaped arrangement of the cables and wires, formed by the first support frame, the outer shell, and the two second support frames, maximizes the use of space at the bottom of the electrical box, reduces cable crossings and tangles, increases the number of cables that can be accommodated, simplifies line management and maintenance, and allows for the installation of more electrical equipment or components within a limited space. Furthermore, the U-shaped area allows for natural convection of hot and cold air inside and outside the U-shaped frame, helping to quickly dissipate the heat generated by electrical components during operation, thus reducing the overall temperature inside the electrical box. The U-shaped arrangement also ensures that each cable has a fixed path, avoiding the risk of short circuits caused by disorderly stacking. Attached Figure Description

Detailed Implementation

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0023] Please refer to Figures 1-4 This utility model proposes a U-shaped layout structure inside an electrical box, including an outer shell 1, which is rectangular. The inner walls of the outer shell 1 are fixedly installed with the same horizontal partition 2 to divide the internal space of the outer shell 1 into an upper half and a lower half. Support frames 3 are fixedly connected to the inner walls on both the left and right sides of the outer shell 1. The same support frame 4 is fixedly installed between the inner walls on the front and rear sides of the outer shell 1. The support frame 4 is U-shaped. Both support frames 3 and 4 are located in the lower half. A U-shaped area is formed between the support frames 3, the outer shell 1, and the two support frames 4. The U-shaped area is used to place wires, cables, and electrical control switches.

[0024] It should be noted that the U-shaped area refers to the U-shaped layout structure. In the U-shaped layout, the wires and cables can enter the outer casing 1 from the bottom, and make a near 90-degree bend on both the left and right sides of the support frame 2 4 (forming the vertical part of the U), and then be electrically connected to the internal components of the support frame 1 3. This arrangement reduces cable crossings, makes the wiring neater and more orderly, and improves heat dissipation efficiency because the U-shaped layout facilitates air circulation, makes it easier to identify and trace the lines because the lines run in a clear direction, simplifies the installation and maintenance process, and makes it easier for technicians to access the lines.

[0025] like Figure 2 and Figure 4As shown, the support frame 2 4 includes a base frame 5 and two upright plates 6. Side plates are provided on both the left and right sides of the base frame 5. The top of the upright plate 6 is fixedly connected to the bottom of the horizontal partition 2. One side of the upright plate 6 is fixedly connected to the corresponding side plate. A flange structure 7 is provided on the top of the upright plate 6. The top of the flange structure 7 is fixedly connected to the bottom of the horizontal partition 2 by bolts. One side of the upright plate 6 is fixedly connected to the corresponding side plate by bolts. A connecting edge 1 8 is fixedly connected to the front side of the upright plate 6. Two connecting edges 2 9 are fixedly connected to the inner wall of the front side of the outer shell 1. Both the connecting edge 1 8 and the corresponding connecting edge 2 9 are L-shaped and fit together.

[0026] It should be noted that the second support frame 4 is assembled and connected by the base frame 5 and two upright plates 6, which improves the ease of installation of the second support frame 4 and the outer shell 1. Furthermore, the stability of the connection between the second support frame 4 and the outer shell 1 is improved by the flange structure 7, the first connecting edge 8, and the second connecting plate.

[0027] like Figure 2 As shown, a rectangular hole is provided at the bottom of the base frame 5, and a base plate 10 is movably attached to the rectangular hole. The base plate 10 is fixedly connected to the base frame 5 by bolts. The base plate 10 and the rectangular hole facilitate the sorting of wires and cables in the U-shaped arrangement structure from above the support frame 4.

[0028] like Figure 2 and Figure 3 As shown, through holes 11 are provided on both the left and right sides of the outer casing 1, and through holes 12 are provided on the rear side of the outer casing 1. Through holes 11 are connected to the corresponding support frame 3, and through holes 12 are connected to the support frame 4. Through holes 11 and 12 are closed by cover plates 13. Electrical components and connectors are provided in the upper half, the support frame 4, and the two support frames 3. Two through holes 3 are provided on the front side of the outer casing 1. Door panels 14 are provided in the through holes 3. Rotary locks are provided on the door panels 14. Multiple holes 15 are provided on one side of the support frame 4. Multiple sleeves 16 are fixedly installed on one side of the support frame 4. The holes 15 and sleeves 16 are used to support the connection of wires and cables with electrical components, so as to realize the basic function of the electrical box as a carrier of electrical components.

[0029] like Figure 3As shown, a right-angle notch 17 is provided on the bottom rear side of the outer casing 1. The right-angle notch 17 is connected to the outer casing 1 and is located below the support frame 4. The same vertical partition 18 is fixedly installed between the bottom inner wall of the outer casing 1 and the bottom of the support frame 4. The right-angle notch 17 allows cables to enter or exit from the bottom of the outer casing 1 without having to go around the entire edge, simplifying the wiring path, reducing the required cable length, and reducing the workload of cable management and fixing. The right-angle notch 17 can also serve as an additional ventilation opening to promote the exchange of air inside and outside the outer casing 1, help dissipate the heat generated inside, reduce the risk of temperature accumulation, and thus improve the stability and lifespan of the system. The right-angle notch can accommodate a power socket on the wall, allowing the electrical box to be flush with the wall.

[0030] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
