[0024] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Please see Figures 1 to 4 The present invention provides a description of the cabinet lightning protection grounding structure and the cabinet itself. The cabinet lightning protection grounding structure includes a cabinet body, a grounding component, and a limiting member 2. The grounding component includes a grounding sheet metal 3 located inside the cabinet body and a grounding bolt that penetrates the grounding sheet metal 3 and the positioning plate 1 of the cabinet body. The limiting member 2 connects the positioning plate 1 of the cabinet body and the grounding sheet metal 3, and has a through hole 11 that allows the grounding bolt to pass through.

[0026] Compared with the prior art, the cabinet lightning protection grounding structure provided by this utility model uses a cabinet panel on one side of the cabinet as a positioning plate 1 to fix the limiting member 2. The grounding sheet metal 3 inside the cabinet is installed inside the cabinet and fixedly connected to the limiting member 2. During installation, the grounding bolt only needs to be passed through the through holes 11 on the positioning plate 1 and the limiting member 2 in sequence and connected to the grounding sheet metal 3. The limiting member 2 positions the grounding sheet metal 3, preventing the grounding sheet metal 3 from shifting during the movement and installation of the cabinet and reducing the deformation of the grounding sheet metal 3. This ensures that the grounding hole on the grounding sheet metal 3 is coaxial with the through hole 11 of the limiting member 2 and the hole of the cabinet positioning plate 1, avoiding the problems of misalignment of holes, inconvenient on-site installation, and low installation accuracy caused by the displacement of the grounding sheet metal 3 when grounding the cabinet.

[0027] Optionally, the through hole 11 has a guide opening 9 on the side near the positioning plate 1. The guide opening 9 is trumpet-shaped, and the inner diameter of the guide opening 9 gradually decreases from the side near the positioning plate 1 toward the inner side of the limiting member 2.

[0028] In some possible embodiments, please refer to Figures 3 to 4 The limiting member 2 is a block structure. The limiting member 2 has a parallel first mounting surface 8 and a second mounting surface 10. The first mounting surface 8 is attached to the positioning plate 1, and the second mounting surface 10 is attached to the grounding sheet metal 3. The through hole 11 passes through the first mounting surface 8 and the second mounting surface 10 laterally.

[0029] The limiting member 2 is located between the positioning plate 1 and the grounding sheet metal 3. The first mounting surface 8 of the limiting member 2 is attached to the inner side wall of the positioning plate 1, and the second mounting surface 10 of the limiting member 2 is attached to the side wall of the grounding sheet metal 3. The through hole 11 of the limiting member 2 is arranged horizontally, and the two ends of the through hole 11 extend to the first mounting surface 8 and the second mounting surface 10, respectively.

[0030] Optionally, the limiting component 2 is a rectangular block structure. The limiting component 2 can be fixed to the positioning plate 1 and the grounding sheet metal 3 by means of adhesive, bolts or snap-fit.

[0031] In some possible embodiments, please refer to Figure 3 Both the first mounting surface 8 and the second mounting surface 10 have snap fasteners, and the positioning plate 1 has connection holes that are adapted to the snap fasteners.

[0032] The two sides of the limiting member 2 are respectively connected to the positioning plate 1 and the grounding sheet metal 3 by means of snap-fit ​​buckles. Taking the snap-fit ​​between the limiting member 2 and the positioning plate 1 as an example, the first mounting surface 8 of the limiting member 2 has snap-fit ​​buckles, and the positioning plate 1 of the cabinet has a connecting hole, which engages with the snap-fit ​​buckle.

[0033] Correspondingly, holes can also be made on the grounding sheet metal 3, and the holes and snap-fit ​​fasteners can be used for snap-fit ​​connection.

[0034] In some possible embodiments, please refer to Figure 3 The snap fastener includes two spaced-apart snap bodies 4, which are symmetrical to each other; the grounding component is located between the two snap bodies 4 on the second mounting surface 10.

[0035] The snap fastener located on the same mounting surface of the limiting member 2 has two symmetrical buckle bodies 4, with two buckle heads located on both sides of the mounting surface.

[0036] Taking the snap-fit ​​connection between the limiting member 2 and the positioning plate 1 as an example, the two buckles 4 on the first mounting surface 8 and the two connecting holes on the positioning plate 1 are snapped together one-to-one. Because the two buckles 4 are spaced apart, the connection of the limiting member 2 is more stable.

[0037] To facilitate the installation and positioning of the grounding sheet metal 3, the grounding sheet metal 3 is confined between two fasteners 4 on the second mounting surface 10 of the limiting member 2, and the grounding sheet metal 3 has a longitudinal degree of freedom.

[0038] Specifically, the two fasteners 4 on the second mounting surface 10 of the limiting member 2 are symmetrically arranged along the longitudinal centerline of the second mounting surface 10, and a longitudinal through groove is formed between the two fasteners 4. The grounding sheet metal 3 is located in the through groove and has the freedom to move along the length of the through groove.

[0039] In some possible embodiments, please refer to Figure 3 and Figure 4 The buckle body 4 includes an extension arm and a buckle head, with the buckle head located at the free end of the extension arm; the side of the buckle head protrudes from the side of the extension arm, and a limiting step is formed at the connection between the buckle head and the extension arm; the two buckle bodies 4 on the first mounting surface 8 are arranged opposite to each other or in opposite directions, and the two buckle bodies 4 on the second mounting surface 10 are arranged opposite to each other; a longitudinal through groove is formed between the two buckle bodies 4 on the second mounting surface 10, and the grounding sheet metal 3 is limited to the through groove.

[0040] The extension arm of the buckle body 4 is perpendicular to the mounting surface and extends outward. The buckle head is located at the free end of the extension arm. The limiting step at the connection between the buckle head and the extension arm is used to engage the positioning plate 1 and the grounding sheet metal 3 to achieve the limiting function.

[0041] The two buckles on the first mounting surface 8 are arranged opposite each other or in reverse order. For example... Figure 3 and Figure 4 As shown, when the two buckles on the first mounting surface 8 are set opposite to each other, the limiting steps of the two buckles face outward. When the buckle passes through the connecting hole on the positioning plate 1, the limiting step fits against the positioning plate 1 outside the connecting hole to achieve the purpose of locking.

[0042] Two buckles on the second mounting surface 10 are positioned opposite each other to form an inwardly facing limit at the opening end of the through groove. When the grounding sheet metal 3 is located in the through groove, the limiting step fits against the side of the grounding sheet metal 3.

[0043] Optionally, the buckle has an inclined guide surface. The guide surface corresponds to the limiting step and is spaced apart from the limiting step.

[0044] In some possible embodiments, please refer to Figure 2 The grounding sheet metal 3 includes a wiring part 6 and a grounding part 7. The wiring part 6 is perpendicularly connected to the grounding part 7. The grounding part 7 is connected to the limiting member 2. The grounding part 7 has a grounding hole, which is coaxial with the through hole 11. The grounding bolt passes through the through hole 11 and the grounding hole in sequence.

[0045] The wiring section 6 is horizontal and is used to install the electrical terminals inside the cabinet. The wiring section 6 has bolt holes, and it contacts the electrical terminals via bolts. The grounding section 7 is vertically connected to the wiring section 6 and has a grounding hole. The grounding section 7 is connected to the limiting member 2, which reduces the deformation of the grounding section 7, thereby ensuring the assembly accuracy of the grounding bolt. A nut 5 is located on the side of the grounding section 7 away from the limiting member 2. The nut 5 is coaxial with the grounding hole and is used to position the grounding bolt.

[0046] Optionally, the free end of the wiring portion 6 has a folded edge structure, and the extension direction of the folded edge structure is opposite to the extension direction of the grounding portion 7.

[0047] Another type of cabinet is provided, which adopts the above-mentioned cabinet lightning protection grounding structure.

[0048] Compared with the prior art, the cabinet provided by this utility model adopts the above-mentioned cabinet lightning protection grounding structure and has all the beneficial effects it possesses. The limiting member 2 positions the grounding sheet metal 3, preventing the grounding sheet metal 3 from shifting during cabinet movement and installation and reducing the deformation of the grounding sheet metal 3. This ensures that the grounding hole on the grounding sheet metal 3 is coaxial with the through hole 11 of the limiting member 2 and the hole of the cabinet positioning plate 1, avoiding the problems of misalignment of holes, inconvenient on-site installation, and low installation accuracy caused by the displacement of the grounding sheet metal 3 when the cabinet is grounded.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
