[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 lightning protection grounding system and cabinet provided by this utility model will now be described. The lightning protection grounding system includes an installation structure, a limiting member 3, and a grounding member 4; the installation structure includes an installation port and a movable part 2, the installation port is opened on the side plate 1, the fixed end of the movable part 2 is connected to the side plate 1, and the free end of the movable part 2 extends into the installation port and has a degree of freedom in the direction perpendicular to the side plate 1; the limiting member 3 is located on the inner side of the cabinet, and the two sides of the limiting member 3 are respectively connected to the movable part 2 and the grounding member 4; the grounding member 4, the limiting member 3, and the movable part 2 have a coaxially arranged through hole structure for installing grounding bolts.

[0026] Compared with the prior art, the lightning protection grounding system provided by this utility model uses the limiting member 3 to fix the grounding member 4 on the movable part 2 of the installation structure, ensuring that the grounding member 4 and the movable part 2 are relatively stably connected, so as to ensure that the grounding member 4, the limiting member 3 and the movable part 2 form a coaxial through hole structure, which is convenient for blind installation and hole alignment on site. In addition, the movable part 2 has a degree of freedom in the direction of the vertical side plate 1, which will increase the activity space at this point when the grounding member 4 is re-locked, further solving the problem of difficulty in locking the grounding bolt during blind installation.

[0027] In some possible embodiments, please refer to Figure 2The grounding component 4 is a grounding terminal, which includes a terminal body and an extension. The extension is connected to the lower edge of the terminal body. The terminal body is U-shaped, and the closed end of the terminal body is connected to the limiting component 3.

[0028] The grounding terminal body is mounted on the limiting member 3. The terminal body has a downwardly extending extension that connects to electrical components inside the cabinet. The terminal body has a U-shaped structure, with its opening facing away from the limiting member 3. The closed end of the terminal body is attached to and fixedly connected to the limiting member 3. Multiple extensions may be present, located on plates on both sides of the closed end of the terminal body.

[0029] In some possible embodiments, please refer to Figure 3 The limiting member 3 is a block structure. The limiting member 3 has a first mounting surface and a second mounting surface that are parallel. The first mounting surface is attached to the movable part 2 and the second mounting surface is attached to the grounding member 4. A through hole 5 is provided on the limiting member 3. The two ends of the through hole 5 extend to the first mounting surface and the second mounting surface respectively, and the axial direction of the through hole 5 is perpendicular to the first mounting surface and the second mounting surface.

[0030] The limiting member 3 is located between the movable part 2 and the grounding member 4. The first mounting surface of the limiting member 3 is attached to the inner sidewall of the movable part 2, and the second mounting surface of the limiting member 3 is attached to the sidewall of the grounding member 4. The through hole 5 of the limiting member 3 is arranged laterally, and its two ends extend to the first mounting surface and the second mounting surface, respectively. The through hole 5 has a guide opening 6 on the side near the movable part 2. The guide opening 6 is trumpet-shaped, and its inner diameter gradually decreases from the side near the movable part 2 toward the inner side of the limiting member 3.

[0031] Optionally, the limiting member 3 is a rectangular block structure. The limiting member 3 can be fixed to the movable part 2, and the limiting member 3 can be fixed to the grounding member 4 by means of adhesive, bolts, or snap-fit.

[0032] In some possible embodiments, please refer to Figure 3 Both the first and second mounting surfaces have snap-fit ​​fasteners, and the movable part 2 has a connection hole that matches the snap-fit ​​fastener.

[0033] The two sides of the limiting member 3 are respectively connected to the movable part 2 and the grounding member 4 by means of snap-fit ​​fasteners. Taking the snap-fit ​​connection between the limiting member 3 and the movable part 2 as an example, the first mounting surface of the limiting member 3 has snap-fit ​​fasteners, and the movable part 2 of the cabinet has a connection hole, which engages with the snap-fit ​​fastener.

[0034] Correspondingly, holes can also be made on the grounding component 4, and the hole body and the snap-fit ​​buckle can be used for snap-fit.

[0035] In some possible embodiments, please refer to Figure 3The snap fastener includes two spaced-apart fastener bodies 7, which are symmetrical to each other.

[0036] The snap fastener located on the same mounting surface of the limiting member 3 has two symmetrical buckle bodies 7, with two buckle heads located on both sides of the mounting surface.

[0037] Taking the engagement between the limiting member 3 and the movable part 2 as an example, the two fasteners 7 on the first mounting surface and the two connecting holes on the movable part 2 are engaged one-to-one. Because the two fasteners 7 are spaced apart, the connection of the limiting member 3 is more stable. Similarly, the two fasteners 7 on the second mounting surface and the holes on the grounding member 4 are engaged accordingly.

[0038] In some possible embodiments, please refer to Figure 3 and Figure 4 The buckle body 7 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.

[0039] The two fasteners 7 on the first mounting surface are arranged opposite to each other or in opposite directions, and the two fasteners 7 on the second mounting surface are arranged opposite to each other. The extension arm of the fastener 7 is perpendicular to the mounting surface and extends outward. The fastener head is located at the free end of the extension arm. The limiting step at the connection between the fastener head and the extension arm is used to engage the movable part 2 and the grounding part 4 to achieve a limiting function.

[0040] The two buckles on the first mounting surface 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 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 movable part 2, the limiting step fits against the movable part 2 outside the connecting hole to achieve the purpose of locking.

[0041] Two buckles on the second mounting surface are positioned opposite each other to form an inwardly facing limit at the open end of the through groove. When the grounding component 4 is engaged on the second mounting surface, the limiting step abuts against the side wall of the closed end of the grounding component 4.

[0042] Optionally, the buckle has an inclined guide surface. The guide surface corresponds to the limiting step and is spaced apart from the limiting step.

[0043] In some possible embodiments, please refer to Figure 1 The mounting opening is a U-shaped punch, and the movable part 2 is located inside the mounting opening and is an integral structure with the side plate 1.

[0044] An installation opening is punched out on the side plate 1. The installation opening is a U-shaped punch with the opening facing horizontally. After punching, a tongue-shaped movable part 2 is formed inside the U-shaped punch. One end of the movable part 2 is connected to the side plate 1, and the other three edges are movable. Therefore, the movable part 2 has a certain degree of freedom. When re-locking, the movement space at this point will be increased to achieve force relief.

[0045] The movable part 2 is formed by directly punching holes in the side plate 1. The movable part 2 and the side plate 1 are an integral structure, and no additional structure is required.

[0046] Another type of cabinet is provided, which adopts the aforementioned lightning protection and grounding system.

[0047] Compared with the prior art, the cabinet provided by this utility model adopts the above-mentioned lightning protection grounding system, which has all the beneficial effects. The limiting member 3 ensures a relatively stable connection between the grounding member 4 and the movable part 2, which is convenient for blind installation and hole alignment on site. The movable part 2 has a degree of freedom in the direction of the vertical side plate 1, which will increase the activity space at this point when the grounding member 4 is re-locked, further solving the problem of difficulty in locking the grounding bolt during blind installation.

[0048] 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.
