DETAILED DESCRIPTION

[0071] Preferred embodiments of the present invention will be described in detail below in conjunction with 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] Embodiment 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 feet fixedly connected to its bottom, which are used to stably place the cabinet 100 on the ground. The side wall of the cabinet 100 is provided with a plurality of heat dissipation holes, which are used to dissipate the heat inside the cabinet 100 to the outside.

[0074] An installation component 300 is installed inside the cabinet 100. The installation component 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 installation 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. One end of the wire 302 close to the electrical component 200 is connected with a connector. The connector is a circular conductive material and is fixed to the power terminal of the electrical component 200 by screws.

[0078] The winding rods 303 have two winding rods 303 , and the two ends of the two winding rods 303 are respectively fixedly connected to the two side walls of the cabinet 100 , and the wires 302 are sequentially wound around the outer walls of the winding rods 303 from the front of the electrical component 200 and form an “S” shape;

[0079] The partition 304 is fixedly connected to the inner wall of the cabinet 100. The partition 304 divides the interior of the cabinet 100 into a plurality of vertical columns. Each column of the regions is provided with multiple layers of electrical components 200.

[0080] The bus duct 305 is fixedly installed on the rear inner wall of the cabinet 100. One 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 a conductor material (copper or aluminum busbar), an insulating material, a metal trough, etc. It is used to distribute a large power to each component of the distributed system and transmit electrical energy. The conductor part of the bus duct 305 has high conductivity, and the metal trough provides good protection, so that the bus duct 305 has higher safety and reliability during power transmission;

[0081] A movable column 306 is disposed below the wire 302;

[0082] The fixed sleeve 307 is fixedly connected to the inner wall of the cabinet 100, the fixed sleeve 307 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, and 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, and the first spring 308 is in a contracted state by default;

[0083] The ring 309 is fixedly connected to the top of the movable column 306, and 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 both ends of the two rotating rollers 3012 are fixedly connected to the side walls of the two rotating disks 3011 respectively;

[0087] The fixed seat 3013 has two parts. The middle parts of the two rotating disks 3011 are rotatably connected to the tops of the two fixed seats 3013 respectively. The rotating positions of the rotating disks 3011 and the fixed seats 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 a socket 201, the plug 3015 is plugged into the socket 201, and the bottom 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 of the electric meter;

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

[0091] The torsion spring 3016 at the end of the turntable 3011 is removed, and a motor is installed on one of the fixed seats 3013, and then the output shaft of the motor is connected to the middle rotating shaft of the turntable 3011, and the turntable 3011 and the roller 3012 are controlled to rotate by the motor, thereby avoiding the torsion spring 3016 from failing or getting stuck;

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

[0093] A protection box 310, which 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, and the bottom of the fixing seat 3013 is fixedly connected to the bottom of the inner wall of the protection box 310;

[0094] A permanent magnet 313, which is disposed on the outer wall of the protection box 310 near the rear of the electrical component 200;

[0096] It should be noted that the magnetic material may be iron, nickel, or cobalt; the non-magnetic material may be copper, aluminum, or zinc, or may be plastic, such as high-strength engineering plastic.

[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 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, so that the permanent magnet 313 is attracted to the inside of the plug slot 202, so that the electrical component 200 is stably fixed and not easy to shake, 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 made. 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 magnet materials and hard magnetic materials. Once magnetized, they can maintain magnetism for a long time. A strong reverse magnetic field is required to make their magnetism disappear. After the external magnetic field is removed, they can still maintain high magnetism. According to the material type, they can be divided into alloy permanent magnet materials and ferrite permanent magnet materials. The mainstream permanent magnets are rare earth permanent magnet materials, such as neodymium iron boron (Nd2Fe14B), aluminum nickel cobalt (AlNiCo), samarium cobalt (SmCo), etc.

[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 with a magnetic field; or mix the powder of magnetic material with polymer resin, press it into shape, and then sinter it at high temperature to form a magnet with magnetic properties;

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 , Fig. 9 , Fig.10 As shown, the installation assembly 300 also includes:

[0105] An extension block 315 is provided at the front end of the partition 304. One end of the extension block 315 close to the partition 304 is hinged to the front end of the partition 304. As shown in FIG10 , the extension block 315 can rotate 90 degrees. An arc portion is provided at the top of the extension block 315, and an arc groove 319 is provided on the side wall of the arc portion.

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

When the extension block 315 is rotated to a vertical state, the arc-shaped portion of the extension block 315 can be received in the receiving groove 317;

[0111] like Fig. 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 a vertical state to a 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.
