Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and in particular to a grounding structure for a metal door cover. Background Technology

[0002] Electrical cabinets are the core carriers used to house and protect electrical components (such as circuit breakers, relays, and cables). They are typically made of metal and are characterized by their robust structure and strong protective performance. Widely used in power, industrial control, and communication fields, they are key equipment for ensuring the stable operation of electrical systems. To prevent dust, moisture, and foreign objects from entering the cabinet and damaging electrical components, and to prevent accidental contact with live parts and reduce the risk of electric shock, cabinet doors are installed on electrical cabinets. Because large door covers are heavy, it is inconvenient to weld them directly to the frame of the electrical cabinet. At the same time, it is also necessary to perform later maintenance on the electrical components inside the electrical cabinet. Therefore, a detachable method is used to install the cabinet door cover on the frame of the electrical cabinet. However, when installing the cabinet door cover on a large electrical cabinet, the heavy weight of the door cover itself, the high precision requirements for assembly, and the dimensional deviations and alignment errors that are easy to occur during installation will reduce the installation efficiency of the cabinet door cover, which will be time-consuming and labor-intensive, affect the overall assembly progress of the electrical cabinet, and may also damage the grounding structure due to forced alignment, resulting in a decrease in grounding stability. Utility Model Content

[0003] This invention provides a grounding structure for a metal door cover to overcome the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A grounding structure for a metal door cover includes a grounding block shell and an adjusting block, both made of conductive material. The grounding block shell is fixed to the outside of the grounding frame of the electrical cabinet, and the outer wall of the grounding block shell abuts against the grounding frame. The adjusting block is located inside the grounding block shell, and the adjusting block has a certain amount of movement between its outer wall in the vertical plane and the inner wall of the grounding block shell. The cabinet door can be installed on the grounding frame via the grounding block housing, the adjusting block, and the fixing components.

[0005] Furthermore, the adjusting block has a sheet-like structure, is vertically disposed inside the grounding block housing, and has threaded holes; The grounding block housing and the front and rear sides of the adjusting block are provided with elongated through holes. The elongated through holes are arranged in the transverse direction. The elongated through holes on the front and rear sides are all connected to the threaded hole. The size of the elongated through holes is larger than the size of the threaded hole. The fastener can pass sequentially through the mounting holes on the cabinet door cover, the elongated through hole, the threaded hole, and the mounting holes on the grounding frame to fix the cabinet door cover to the grounding frame.

[0006] Furthermore, both the grounding block housing and the adjusting block are made of stainless steel.

[0007] Furthermore, the amount of movement of the adjustment block is D, and the range of D is 1mm-3mm.

[0008] Furthermore, the grounding block housing includes a housing body mounted on a grounding frame and detachable covers disposed on both sides of the housing body.

[0009] Furthermore, the grounding block housing is fixed to the grounding frame by welding or bolting.

[0010] Furthermore, the surface of the area where the cabinet door cover contacts the outer shell of the grounding block has no insulating material.

[0011] Furthermore, the grounding frame is connected to the ground via a conductive structure.

[0012] The beneficial effects of this utility model are: This utility model discloses a grounding structure for a metal door cover. Through the grounding block shell and the adjustable block structure that can move flexibly in both vertical and horizontal directions, it provides adjustable range for the cabinet door cover in both vertical and horizontal directions.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Example: like Figure 1-2 The diagram shows a grounding structure for a metal door cover provided in this embodiment, comprising a grounding block shell 1 and an adjusting block 2, both made of conductive material (neither the inside nor the outside of the grounding block shell 1 is coated with insulating material); the grounding block shell 1 is fixed to the outside of the grounding frame 3 of the electrical cabinet, and the outer wall of the grounding block shell 1 abuts against the grounding frame 3; the adjusting block 2 is disposed inside the grounding block shell 1, and the adjusting block 2 has a certain amount of movement between its outer wall in the vertical plane and the inner wall of the grounding block shell 1, that is, there is a gap between the outer wall of the adjusting block 2 in the vertical plane and the inner wall of the grounding block shell 1, and the adjusting block 2 is movably disposed inside the grounding block shell 1 in the vertical plane; The cabinet door cover 4 can be installed on the grounding frame 3 through the grounding block housing 1, the adjusting block 2, and the fixing component. The adjustable block 2 is movably located inside the grounding block housing 1. The amount of movement of the adjusting block 2 in the vertical plane inside the grounding block housing 1 can compensate for the dimensional deviation or assembly error of the cabinet door cover 4 during installation. This allows the fixing component to be quickly aligned with the elongated through hole and threaded hole without repeated fine-tuning of the cabinet door cover 4, thereby reducing the steps of assembling the cabinet door cover on the grounding frame and shortening the installation time.

[0017] The cabinet door cover 4 is a metal door cover. The grounding block shell 1 and the adjusting block 2 are both made of conductive materials. The grounding block shell 1 is not coated with an insulating layer and is tightly abutting against the grounding frame 3, forming a complete conductive link of cabinet door cover → grounding block shell → adjusting block → grounding block shell → grounding frame (conductive structure). This ensures that there will be no risk of electric sparks or electric shock due to potential difference between the door cover and the frame during the operation of electrical equipment. At the same time, it provides a safe discharge channel for fault current, static electricity, etc., ensuring the safe operation of the equipment and the personal safety of the operators.

[0018] This utility model discloses a grounding structure for a metal door cover. Through the grounding block housing and the adjustable block structure that can move flexibly in both vertical and horizontal directions, it provides adjustable range for the cabinet door cover in both vertical and horizontal directions. This effectively compensates for potential dimensional deviations and assembly errors during installation, allowing workers to smoothly complete the cabinet door installation process without repeated alignment. This improves the assembly efficiency of individual components and ensures the overall assembly progress of the electrical cabinet, while also ensuring that the stability of the grounding connection is not affected by installation accuracy. The grounding block housing and the adjustable block structure are made of conductive material, ensuring a conductive connection between the cabinet door cover and the grounding frame, thereby guaranteeing equipotential between them, eliminating the risk of electric shock and sparks, and ensuring the safety of equipment and personnel.

[0019] In a specific embodiment, the adjustment block 2 is a sheet-like structure, the adjustment block 2 is vertically disposed inside the grounding block housing 1, and the adjustment block 2 is provided with a threaded hole 21; The grounding block housing 1 and the front and rear sides of the adjusting block 2 are provided with elongated through holes 11. The elongated through holes 11 are arranged in the transverse direction. The elongated through holes 11 on the front and rear sides are all connected to the threaded holes 21. The size of the elongated through holes 11 is larger than the size of the threaded holes 21. The fastener can pass sequentially through the mounting hole 41 on the cabinet door cover 4, the elongated through hole 11, the threaded hole 21, and the mounting hole on the grounding frame 3, to fix the cabinet door cover 4 to the grounding frame 3, ensuring a firm connection and stable grounding path after fixing. The size difference between the elongated through hole 11 and the threaded hole 21 provides lateral movement space for the fastener, further ensuring the left and right adjustment range of the cabinet door cover 4 during installation and further improving installation efficiency.

[0020] In a specific embodiment, both the grounding block housing 1 and the adjusting block 2 are made of stainless steel. On the one hand, this ensures that the strength design of the grounding block housing 1 and the adjusting block 2 meets the strength required when the cabinet door 4 is connected by the two and the fasteners (bolts), thus ensuring the connection stability between the cabinet door 4 and the grounding frame 3 (electrical cabinet). On the other hand, it ensures that the conductive path between the cabinet door 4 and the grounding frame 3 remains reliable, while the corrosion resistance of stainless steel can prevent the oxidation and rust of components, thus maintaining the stability of the grounding performance and connection structure over a long period of time.

[0021] In a specific embodiment, the amount of movement of the adjustment block is D, and the range of D is 1mm-3mm. This setting range is sufficient to compensate for dimensional deviations and assembly errors during installation, ensuring quick alignment and installation of the cabinet door cover, while also avoiding excessive movement that could cause the door cover to loosen after installation, thus ensuring the stability of the cabinet door cover installation and maintaining the stability of the connection and grounding.

[0022] In a specific embodiment, the grounding block housing 1 includes a housing body 12 mounted on the grounding frame 3 and detachable covers 13 disposed on both sides of the housing body 12. The housing body 12 is mounted on the grounding frame 3 by welding or bolting, and the housing body 12 and the covers 13 are connected by screws 14. The screws 14 do not affect the position adjustment of the adjusting block 2. When the adjusting block 2 is worn or deformed due to long-term use, affecting the grounding or connection performance, it is not necessary to disassemble the entire grounding block housing 1. Only the covers 13 need to be removed to quickly inspect and repair the adjusting block 2, reducing maintenance costs and operational difficulties, and facilitating the maintenance or replacement of the adjusting block 2 in the future.

[0023] In a specific embodiment, the grounding block housing 1 and the grounding frame 3 are fixed by welding or bolting to ensure that the connection between the two is firm and the conductive path is stable, so as to avoid the grounding effect and the stability of the door cover installation due to loose connection.

[0024] In a specific embodiment, the surface of the area where the cabinet door cover 4 contacts the grounding block shell 1 is free of insulating material, so as to ensure that the cabinet door cover and the grounding block shell 1 are directly conductive and maintain the continuity of the path from door cover to grounding block shell 1 to grounding frame 3.

[0025] In a specific embodiment, the grounding frame 3 is connected to the ground through a conductive structure, such as a grounding terminal plate or a grounding wire, to form a complete grounding loop, safely conducting static electricity and fault current on the door cover and cabinet to the ground, thereby achieving the grounding protection function.

[0026] The steps for installing the cabinet door 4 onto the grounding frame 3 are as follows: 1. First, fix the grounding block housing 1 on the grounding frame 3 (outer side), and then vertically insert the adjusting block 2 into the grounding block housing 1 (it is not necessary to place the adjusting block every time it is used in subsequent applications). 2. Align the mounting hole 41 of the cabinet door cover 4 with the elongated through hole 11 of the grounding block outer shell 1, and pass the bolt through the mounting hole 41 and the elongated through hole 11 of the door cover, and initially align it with the threaded hole 21 of the adjusting block 2; 3. Use the adjustment block's movement (up and down, left and right) to fine-tune the door cover position to compensate for deviations, so that the bolts can be accurately and quickly inserted into the threaded hole 21 and screwed into the mounting hole of the grounding frame 3. 4. Tighten the bolts to secure the cabinet door to the grounding frame, while maintaining the grounding path.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
