When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0023] Furthermore, it should be noted that the directional terms such as left, right, up, and down used in the embodiments of this utility model are only relative concepts or references to the normal use of the product, and should not be considered restrictive. The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] As attached Figure 1 The diagram shows a modular, quick-maintain, pluggable switch cabinet according to this utility model, comprising a cabinet body 1, and several drawers 2 arranged along the height direction inside the cabinet body 1, as shown in the attached diagram. Figure 2 As shown, a circuit breaker 3 is installed inside drawer 2. Drawer 2 includes a bottom plate 21, a front panel 22 facing the outside of cabinet 1, a rear panel 23 near the inside of cabinet 1, and a first side panel 24 and a second side panel 25 connecting the front panel 22 and the rear panel 23. The front panel 22, the first side panel 24, the rear panel 23, and the second side panel 25 surround the bottom plate 21. (See attached diagram) Figure 3 As shown, the base plate 21 has a first opening 211, and the edge of the first opening 211 has a first mounting plate 212 bent upwards perpendicular to the base plate 21. The first side plate 24 has a second opening 241, and the edge of the second opening 241 has a second mounting plate 242 bent inwards perpendicular to the first side plate 24. The second mounting plate 242 is attached to the first mounting plate 212. The back of the circuit breaker 3 is attached to the first mounting plate 212. The circuit breaker 3 has several connection holes. The first mounting plate 212 has first mounting holes 213 corresponding to the connection holes, and the second mounting plate 242 has second mounting holes corresponding to the first mounting holes 213. The circuit breaker 3 is connected to the first mounting plate 212 by fasteners passing through the first mounting holes 213 and the connection holes. The first mounting plate 212 is integrally bent with the base plate 21, simplifying the structure. It eliminates the need to connect accessories for mounting the circuit breaker 3 to the base plate 21, reducing the number of parts, lowering part costs, simplifying the assembly process, and improving assembly efficiency. The second mounting plate 242, extending from the first side plate 24 after bending, abuts against the first mounting plate 212. Fasteners for mounting the circuit breaker 3 pass through both the first mounting hole 213 and the second mounting hole, locking the first mounting plate 212 and the second mounting plate 242 together. This makes the second mounting plate 242 a support for the first mounting plate 212, increasing its strength and preventing deformation. In this embodiment, the first mounting plate 212 is concave, and the second mounting hole is located at the end of the second mounting plate 242, overlapping with the concave shape. The second mounting hole is elongated, allowing for some tolerance during the bending process of the second mounting plate 242, making installation smoother. The first opening 211 and the second opening 241 formed for bending the first mounting plate 212 and the second mounting plate 242 also serve as ventilation and heat dissipation functions, resulting in a simple and practical structure.

[0025] The rear panel 23 is equipped with an input actuator 4 and an output actuator 5, which are connected to the incoming and outgoing cables of the circuit breaker 3, respectively. The inner side of the cabinet 1 is equipped with an incoming socket and an outgoing socket. The input actuator 4 and the output actuator 5 are plugged into and unplugged from the incoming socket and the outgoing socket, and the switch is performed when the drawer 2 is pulled out and the cabinet 1 is pushed back.

[0026] The cabinet 1 is equipped with partitions 6 that correspond to the drawers 2, as shown in the attached diagram. Figure 4 As shown, the partition 6 includes a horizontal support plate 61 and side folding plates 62 that are bent upwards perpendicular to both sides of the support plate 61. The two ends of the side folding plates 62 have mounting pieces 621 that are attached to the inside of the cabinet 1. The mounting pieces 621 are machined with through holes 622 so that the partition 6 can be connected to the inner wall of the cabinet 1 by fasteners.

[0027] The portion of the side folding plate 62 located between the mounting pieces 621 has a horizontal first folding plate 623 that is bent inwards. The end of the first folding plate 623 has a second folding plate 624 that is bent downwards. Rollers 7 are mounted on both sides of the drawer 2, and the rollers 7 roll along the surface of the support plate 61, as shown in the attached figure. Figure 5 As shown, the roller 7 is located between the side folding plate 62 and the second bending plate 624, making the drawer 2 move more smoothly and preventing it from shifting. The unfolded plan of the partition 6 is square, which improves the utilization rate of the board material, reduces waste, and saves costs.

[0028] An operating handle 8 is mounted on the outer side of the front panel 22, and a toggle assembly for switching the closed and open states of the circuit breaker 3 is mounted on the inner side of the front panel 22. The toggle assembly is connected to the operating handle 8. This structure is conventional technology in the field and will not be described in detail here. An instrument panel 9 for displaying electrical operating parameters is mounted on one side of the operating handle 8. The operating handle 8 includes a handle rod 81 for gripping. In this embodiment, the length of the handle rod 81 is greater than 8cm, making it convenient to grasp and pull out the drawer 2 with the entire hand, eliminating the need for an additional handle, reducing costs, and making the drawer 2 look more concise and aesthetically pleasing. The distance between the bottom of the front panel 22 and the bottom plate 21 is greater than 18mm, making it easy to grip the front panel from the bottom and pull out the drawer 2, providing auxiliary force to the handle rod 81.

[0029] This utility model discloses a modular, quick-maintainable, pluggable switch cabinet with fewer accessories, reducing costs, avoiding cumbersome assembly, and improving efficiency.
