Therefore, when connecting the cables behind the electrical components, the electrical components need to be placed horizontally. This process is relatively cramped inside the narrow cabinet. The solution in the prior art is usually to stretch the cables so that the electrical components and the cables can be plugged into the outside of the cabinet or at the cabinet door. For example, the cable fixing device and method based on intelligent power distribution engineering construction disclosed in prior art publication number CN118693621B achieves the purpose of facilitating installation by stretching the cables so that they can be connected to the sockets at the rear end of the electrical components.

[0071] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the embodiments of the present invention.

[0072] Example 1: Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment provides a modular power distribution cabinet with a multi-layer wiring structure, which includes:

[0073] The cabinet 100 has support legs fixedly connected to its bottom for stably placing the cabinet 100 on the ground. The side walls of the cabinet 100 are provided with a plurality of heat dissipation holes for dissipating the heat inside the cabinet 100.

[0074] The mounting assembly 300 is installed inside the cabinet 100. The mounting assembly 300 is used to divide the electrical components 200 into multiple layers and install them inside the cabinet 100. The electrical components 200 may be circuit breakers, electric meters, or other components.

[0075] like Figure 4 、 Figure 5 、 Figure 6 As shown, the mounting assembly 300 includes:

[0076] The cable assembly 301 is installed in the gap between the rear inner wall of the cabinet 100 and the rear of the electrical component 200;

[0077] The wire 302 is installed below the electrical component 200. The end of the wire 302 close to the electrical component 200 is connected to a connector. The connector is made of a circular conductive material and is fixed to the power terminal of the electrical component 200 by screws.

[0078] There are two winding rods 303, each of which has two ends fixedly connected to the two side walls of the cabinet 100. The wires 302 are sequentially wound around the outer walls of the winding rods 303 from the front of the electrical component 200, forming an "S" shape.

[0079] Partition 304, which is fixedly connected to the inner wall of the cabinet 100, and divides the interior of the cabinet 100 into multiple vertical columns, each of which is equipped with multiple layers of electrical components 200;

[0080] The bus duct 305 is fixedly mounted on the rear inner wall of the cabinet 100. The end of the wire 302 away from the electrical component 200 is connected to the bus duct 305. One end of the bus duct 305 is connected to an external power source and signal source. The bus duct 305 is mainly composed of conductive materials (copper or aluminum busbars), insulating materials, and metal ducts. It is used to distribute high power to various components of the distributed system and transmit electrical energy. The conductive portion of the bus duct 305 has high conductivity, and the metal duct provides good protection, making the bus duct 305 more safe and reliable during power transmission.

[0081] a movable post 306 disposed below the wire 302;

[0082] A fixed sleeve 307 is fixedly connected to the inner wall of the cabinet 100 and is located below the wire 302. The outer wall of the movable column 306 is slidably connected to the inner wall of the fixed sleeve 307. A first spring 308 is connected between the bottom of the movable column 306 and the bottom of the inner wall of the fixed sleeve 307. The first spring 308 is in a retracted state by default.

[0083] The ring 309 is fixedly connected to the top of the movable column 306. The ring 309 is sleeved on the outside of the wire 302. When the wire 302 is pulled toward the electrical component 200, the wire 302 can drive the ring 309 and the movable column 306 to slide upward, thereby causing the first spring 308 to extend. It should be noted that the state in the figure is the state after stretching, and the first spring 308 is in an extended state.

[0084] like Figure 5 、 Figure 7 As shown, the cable assembly 301 includes:

[0085] The turntable 3011 has two;

[0086] There are two rotating rollers 3012, and the two ends of the two rotating rollers 3012 are fixedly connected to the side walls of the two rotating disks 3011 respectively;

[0087] The fixing base 3013 has two parts. The middle parts of the two rotating disks 3011 are rotatably connected to the top parts of the two fixing bases 3013 respectively. The rotating parts of the rotating disks 3011 and the fixing bases 3013 are also connected to torsion springs 3016.

[0088] The cable body 3014 is wound around two rollers 3012 to form a Figure 8 In the state shown, the top of the flat cable body 3014 is connected to a plug 3015, the rear end of the electrical component 200 is connected to the socket 201, the plug 3015 is plugged into the socket 201, and the bottom end of the flat cable body 3014 is connected to the bus duct 305. When the electrical component 200 is an electric meter, the flat cable body 3014 is used to transmit data from the electric meter.

[0089] like Figure 8 As shown, in the above solution, under the action of the torsion spring 3016, the rotating disk 3011 and the rotating roller 3012 can rotate to Figure 8 The diagram on the left shows the state when the cable body 3014 is Figure 8 When the cable body 3014 is pulled in the direction of the right diagram, the turntable 3011 and the two rollers 3012 can be driven to rotate, thereby gradually forming Figure 8 The state of the diagram on the right side is that when the cable body 3014 is not pulled by external force, the cable body 3014 is Figure 8 The status of the schematic diagram on the left;

[0090] It should be noted that, as another feasible solution, the solution in which the rotating disk 3011 and the rotating roller 3012 are rotated by the torsion force of the torsion spring 3016 can also be replaced with the following solution:

[0091] Remove the torsion spring 3016 at the end of the turntable 3011 and install a motor on one of the fixed seats 3013. Then connect the output shaft of the motor to the central rotating shaft of the turntable 3011. The motor is used to control the rotation of the turntable 3011 and the roller 3012, thereby preventing the torsion spring 3016 from failing or getting stuck.

[0092] like Figure 5 、 Figure 6 As shown, the installation assembly 300 also includes:

[0093] The protection box 310 is fixedly connected to the inner wall of the cabinet 100 and is disposed on the rear inner wall of the cabinet 100. The protection box 310 is used to protect the cable assembly 301. The bottom of the fixing base 3013 is fixedly connected to the bottom of the inner wall of the protection box 310.

[0094] The permanent magnet 313 is arranged on the outer wall of the protection box 310 near the rear of the electrical component 200;

[0095] A second spring 314, the two ends of which are connected to the permanent magnet 313 and the outer wall of the protective box 310 respectively. A plug-in slot 202 is provided at the rear of the electrical component 200, which matches the position and size of the permanent magnet 313. The inner wall of the plug-in slot 202 is provided with a magnetic material, which can be metal or a magnet. The entire housing of the electrical component 200 is made of non-magnetic material. The second spring 314 is in a retracted state by default.

[0096] It should be noted that the magnetic materials mentioned above may be iron, nickel, and cobalt; the non-magnetic materials may be copper, aluminum, zinc, or plastics, such as high-strength engineering plastics;

[0097] In the above solution, when the electrical component 200 is close to the permanent magnet 313, the permanent magnet 313 and the magnetic material inside the plug-in slot 202 are attracted to each other, and the attraction force is greater than the restoring force of the second spring 314, so that the permanent magnet 313 stretches the second spring 314, causing the permanent magnet 313 to be attracted to the inside of the plug-in slot 202, thereby stably fixing the electrical component 200 and preventing it from shaking, thereby achieving a stable installation effect;

[0098] It should be noted that permanent magnets, that is, permanent magnets, can be natural products, also known as natural magnets, or they can be artificially manufactured. The following is a detailed introduction to permanent magnets:

[0099] Permanent magnets are materials with wide hysteresis loops, high coercive force, and high remanence. Once magnetized, they can maintain constant magnetism. They are also called permanent magnets or hard magnetic materials. Once magnetized, they can maintain their magnetism for a long time. A strong reverse magnetic field is required to demagnetize them. After the external magnetic field is removed, they can still maintain a high degree of magnetism. According to the material type, they can be divided into alloy permanent magnets and ferrite permanent magnets. The mainstream permanent magnets are rare earth permanent magnets, such as neodymium iron boron (Nd2Fe14B), aluminum nickel cobalt (AlNiCo), and samarium cobalt (SmCo).

[0100] Production process: Mix metals such as iron, nickel, cobalt, aluminum, titanium, and boron together and melt them at high temperature, then cool and magnetize them using a magnetic field; or mix magnetic material powder with polymer resin, press into shape, and then sinter at high temperature to form a magnet with magnetic properties;

[0101] like Figure 5 As shown, the installation assembly 300 also includes:

[0102] The cable outlet 311 is provided at the top of the protection box 310 , and the cable body 3014 can be led out from the cable outlet 311 ;

[0103] The wire inlet groove 312 is opened at the bottom of the protective box 310. The cable body 3014 enters the interior of the protective box 310 from the wire inlet groove 312. The edges of the wire inlet groove 312 and the wire outlet groove 311 are both provided with arc transitions to prevent the cable body 3014 from being scratched during movement.

[0104] like Figure 6 、 Figure 9 、 Figure 10 As shown, the installation assembly 300 also includes:

[0105] Extension block 315, which is disposed at the front end of partition 304. One end of extension block 315, which is close to partition 304, is hinged to the front end of partition 304. As shown in Figure 10, extension block 315 can rotate 90 degrees. The top of extension block 315 is provided with an arc-shaped portion, and the side wall of the arc-shaped portion is provided with an arc-shaped groove 319.

[0106] A rear chute 316 is provided on the side wall of the partition 304;

[0107] The front chute 318 is provided on the side wall of the extension block 315. The front chute 318 and the rear chute 316 can form a whole horizontal chute. The bottom end of the arc-shaped groove 319 is connected to the interior of the front chute 318.

[0108] A sliding plate 320 is provided below the electrical component 200 and is used to hold the electrical component 200 so that the electrical component 200 can be fixed on the sliding plate 320 ;

[0109] Sliding posts 321 are fixedly connected to both ends of the sliding plate 320 , and there are two sliding posts 321 on the same side of the sliding plate 320 , one in front and one in back. The sliding posts 321 are slidably connected to the interior of the rear sliding groove 316 and the front sliding groove 318 ;

[0110] A receiving groove 317 is provided at the front end of the partition 304. The shape of the receiving groove 317 matches the shape of the arcuate portion of the extension block 315. When the extension block 315 is rotated to a vertical position, the arcuate portion of the extension block 315 can be received in the receiving groove 317.

[0111] like Figure 9 As shown, in the above scheme, when the electrical component 200 needs to be installed, the extension blocks 315 on both sides of the electrical component 200 to be installed are first rotated from the vertical state to the horizontal state, so that the rear slide groove 316 and the front slide groove 318 form a complete slide groove, and then the sliding plate 320 is slid from the inside of the cabinet 100 to the front of the cabinet 100. When the sliding plate 320 slides to the front end of the front slide groove 318, the sliding plate 320 is rotated so that the sliding column 321 at the rear of the sliding plate 320 slides in the arc groove 319, and finally the sliding plate 320 is rotated another ninety degrees so that the sliding plate 320 forms a horizontal state. Then, the electrical component 200 to be installed is placed on the sliding plate 320, and then the sliding plate 320 and the electrical component 200 are installed in the opposite manner in sequence. Figure 9 In the order of ③, ②, and ①, slide the sliding plate 320 and the electrical component 200 into the interior of the cabinet 100;

[0112] When the sliding plate 320 and the electrical component 200 are in state ③, the cable body 3014 is pulled so that the plug 3015 at the top of the cable body 3014 is plugged into the socket 201 on the electrical component 200, thereby completing the installation of the cable body 3014. Then, the sliding plate 320 and the electrical component 200 are rotated to state ②. At this time, under the action of the torsion spring 3016, the turntable 3011 and the roller 3012 rotate to wind the cable body 3014, so that the cable body 3014 generates a pulling force toward the inside of the cabinet 100 on the electrical component 200, pulling the electrical component 200 to a specified position inside the cabinet 100, so that the electrical component 200 moves to state ①. Then, the wire 302 is connected to the terminal on the front of the electrical component 200, thereby completing the installation of the electrical component 200.

[0113] like Figure 11 As shown, the figure shows the internal structure of the cabinet 100. In this embodiment, there are three layers and three columns of nine slots for installing electrical components 200 inside the cabinet 100. It should be noted that those skilled in the art can make specific settings for the slots inside the cabinet 100 according to actual needs.

[0114] Embodiment 2: This embodiment differs from the embodiment 1 in that it provides a method for using a modular power distribution cabinet with a multi-layer wiring structure, including the following steps:

[0115] S1. Rotate the extension blocks 315 on both sides of the electrical component 200 to be installed from a vertical position to a horizontal position, so that the rear slide groove 316 and the front slide groove 318 form a complete slide groove;

[0116] S2. Slide the sliding plate 320 from the inside of the cabinet 100 toward the front of the cabinet 100. When the sliding plate 320 slides to the front end of the front sliding groove 318, rotate the sliding plate 320 so that the sliding post 321 at the rear of the sliding plate 320 slides in the arc-shaped groove 319. Finally, rotate the sliding plate 320 another 90 degrees so that the sliding plate 320 is horizontal. Then, place the electrical component 200 to be installed on the sliding plate 320.

[0117] S3. Pull the cable body 3014 so that the plug 3015 at the top of the cable body 3014 is plugged into the socket 201 on the electrical component 200, thereby completing the installation of the cable body 3014.
