Figure 1-5 The grounding device for reinforcing an electrical cabinet shown is used for grounding the electrical cabinet body 2 and includes: a grounding plate 1, a plug-in assembly, and a protection assembly; It should be noted that the grounding plate 1 is located at the bottom of the inner wall of the electrical cabinet 2. Multiple grounding fixing parts are provided on the side of the grounding plate 1. The plug-in components are symmetrically arranged on the side of the grounding plate 1. The plug-in components are used to fix the grounding plate 1 to the inner wall of the electrical cabinet 2.

Specifically, the protective components include a connecting part located on the side opposite to the door of the electrical cabinet 2, and a locking part for limiting the connecting part is provided on the inner wall side of the electrical cabinet 2. It should be noted that the fixing part includes limiting bolts 4, and the ends of multiple limiting bolts 4 are all inserted and connected to the side of the grounding plate 1. The limiting bolts 4 are used for grounding connection of electrical components. Specifically, the side of the grounding plate 1 is provided with multiple threaded grooves for the insertion of the limit bolts 4. When the insulation of electrical appliances (such as switches and instruments) inside the electrical cabinet 2 is damaged, the cabinet door may become energized due to contact with live parts. The grounding wire can directly conduct the leakage current to the ground, so that the cabinet door potential is always close to zero (ground potential), thus avoiding electric shock accidents when personnel touch it.

[0021] It should be noted that the connecting part includes: connecting wire 5, protective wire 6, fixing screw 7, and misalignment part; Specifically, one end of the connecting wire 5 is located on the outside of one of the limiting bolts 4, one end of the protective wire 6 is located on the inner wall of the door of the electrical cabinet 2, the end of the fixing screw 7 is sequentially inserted and connected to one end of the protective wire 6 and the inner wall of the door of the electrical cabinet 2, and the misaligned part is located at the intersection of the other end of the connecting wire 5 and the other end of the protective wire 6. It should be noted that the misalignment part is used to limit the connection wire 5 and the protective wire 6. One end of the connection wire 5 is sleeved on the outside of the limiting bolt 4, and one end of the protective wire 6 is sleeved on the fixing screw 7. The inner wall of the door of the electrical cabinet 2 is provided with a threaded groove for the fixing screw 7 to pass through. The fixing screw 7 limits and fixes the protective wire 6. The connection wire 5 and the protective wire 6 are made of copper wire, and both ends are connected by copper sheet terminals. Specifically, the misaligned part includes: interlaced pillars 11 and interlaced holes 12; It should be noted that multiple staggered posts 11 are respectively set at the other end of the connecting wire 5 and the protective wire 6, the ends of the multiple staggered posts 11 are inserted and connected to the connection point of the connecting wire 5 and the protective wire 6, and multiple staggered holes 12 are respectively set at the other end of the connecting wire 5 and the protective wire 6. Specifically, multiple interlaced holes 12 are used for the insertion of interlaced posts 11. The other ends of the interlaced posts 11 and the connecting wire 5 and the protective wire 6 are fixed by welding. The interlaced posts 11 and the interlaced holes 12 are used for insertion and limiting, thereby limiting the other end of the connecting wire 5 and the other end of the protective wire 6. Furthermore, the locking part includes: a reinforcing plate 8, a threaded sleeve 9, a locking bolt 10, and an anti-loosening component; It should be noted that the reinforcing plate 8 is set on the inner wall of the electrical cabinet 2, the threaded sleeve 9 is set on the side of the reinforcing plate 8, the end of the locking bolt 10 is sequentially inserted and connected to the connection between the connecting wire 5 and the protective wire 6 and the middle of the threaded sleeve 9, and the anti-loosening component is set in the middle of the threaded sleeve 9. Specifically, the reinforcing plate 8 is welded to the inner wall of the electrical cabinet 2, the threaded sleeve 9 is glued to the reinforcing plate 8, the anti-loosening component is used to prevent the locking bolt 10 from loosening, and the threaded sleeve 9 is made of insulating plastic.

[0022] Specifically, the anti-loosening components include: a compression spring 14 and a limiting protrusion 13; It should be noted that the compression spring 14 is located in the middle of the threaded sleeve 9. One end of the compression spring 14 is inserted and connected to the end of the locking bolt 10, and the other end of the compression spring 14 is fixedly connected to the inner wall of the threaded sleeve 9. The limiting protrusion 13 is located in the middle of the compression spring 14 and is located on the inner wall of the threaded sleeve 9. Specifically, the end of the locking bolt 10 is provided with a cylindrical protrusion for inserting into the middle of the compression spring 14. The other end of the compression spring 14 is welded to the inner wall of the threaded sleeve 9. The limiting protrusion 13 is welded to the inner wall of the threaded sleeve 9. The limiting protrusion 13 is used to limit the deformation of the compression spring 14. Example 2: A plug-in assembly applied to the grounding device for reinforcing the electrical cabinet in Example 1; It should be noted that the plug-in assembly includes fixing bolts 3, and the ends of multiple fixing bolts 3 are symmetrically inserted and connected to the connection between the ground plate 1 and the electrical cabinet 2. The fixing bolts 3 are used to fix the ground plate 1. Specifically, the grounding plate 1 and the electrical cabinet 2 have through holes for fixing bolts 3 to pass through. The fixing bolts 3 passing through the electrical cabinet 2 are threadedly connected to the grounding conductive plate in the wall, thus reinforcing the electrical cabinet 2 and also providing grounding protection. The electrical cabinet 2, the grounding plate 1 and the fixing bolts 3 are all made of stainless steel to avoid corrosion affecting grounding.

[0023] In practical use, a connecting part for grounding protection of the cabinet door is provided on the opposite side of the grounding plate 1 inside the electrical cabinet 2 and the inner wall of the cabinet door. This design provides a locking part on the inner wall of the electrical cabinet 2. By limiting the connecting wire 5 and the protective wire 6 through the locking part, the grounding connecting wire 5 and the protective wire 6 are constrained and limited to the inner wall of the electrical cabinet 2, avoiding the problem of loosening of the connecting part due to the force pulling when the cabinet door is opened caused by the entanglement and chaos of the connecting part.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
