[0001] This application relates to the field of power equipment technology, and in particular to a novel grounding grid connector. Background Technology

[0002] In power systems, the grounding grid of transmission and distribution lines is a crucial component ensuring the safe and stable operation of the power system. The connection method of the grounding grid directly affects the safety and reliability of the entire system. Currently, the main connection methods between grounding grids include arc welding and clamp connections. While arc welding provides high connection strength and good electrical continuity, it requires specialized equipment and operators during construction, and the welding quality is easily affected by the environment and the operator's skill level, posing a high fire safety risk. Furthermore, the welded connectors are difficult to disassemble and replace, hindering later maintenance and modifications. Although clamp connections are convenient to install and disassemble, they are prone to corrosion and rust at the connection points, and under high current conditions, the contact resistance is high, affecting the performance of the grounding system.

[0003] To address the aforementioned issues, there is an urgent need to provide a new type of grounding grid connector that improves connection reliability, enhances corrosion resistance, facilitates installation and maintenance, and increases adaptability. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a new type of grounding grid connector that improves connection reliability, enhances corrosion resistance, facilitates installation and maintenance, and improves adaptability.

[0005] To achieve the above technical objectives, this application provides a novel grounding grid connector, including a main structure and connecting parts;

[0007] The connector has a central cavity, and both ends of the connector have connection ports that communicate with the central cavity;

[0008] One end of the connector is connected to one of the connecting ends of the main structure;

[0009] The other end of the connector is for inserting a grounding electrode;

[0010] The connection end can come into contact with and abut against the grounding body;

[0011] The connector is crimped to the grounding electrode.

[0012] Furthermore, the connector is provided with a first crimping portion;

[0013] The grounding electrode is in seamless contact with the first crimping part.

[0019] Furthermore, the connector is pressed into the main structure;

[0020] The connector is provided with a second crimping part;

[0021] The connecting end is in seamless contact with the second crimping part.

[0036] This application discloses a novel grounding grid connector.

[0037] Please see Figure 1 One embodiment of the novel grounding grid connector provided in this application includes:

[0038] Main structure 1 and connecting parts 2.

[0039] The main structure 1 is provided with at least one connecting end 11; the main structure 1 can be in the shape of a straight line, a cross, or a T. The straight line has two connecting ends 11, the cross has four connecting ends 11, and the T has three connecting ends 11. Of course, it is not limited to the above shapes. The specific shape and the number of connecting ends 11 can be designed according to actual needs and are not limited.

[0040] The connector 2 is provided with a central cavity 21, and both ends of the connector 2 are provided with connecting end 11 ports that communicate with the central cavity 21; one end of the connector 2 is connected to one connecting end 11 of the main structure 1; the other end of the connector 2 is for the insertion of a grounding body (not shown in the figure).

[0041] Connection end 11 can contact and abut against the grounding body; connection part 2 is crimped to the grounding body.

[0042] The novel grounding grid connector designed in this application has the following beneficial effects:

[0043] 1. Improved connection reliability: Traditional welding connections are prone to defects such as porosity and slag inclusions, affecting connection strength and electrical continuity, while bolted connections are prone to loosening, leading to increased contact resistance. This application employs a crimping method for grounding electrodes, which offers advantages such as fast connection speed, high strength, and low contact resistance. Furthermore, the installation process is very convenient, ensuring stable connections under various operating conditions and guaranteeing the safe operation of the grounding system.

[0044] 2. No need to measure the protruding length of the grounding electrode; the main structure 1 is designed to not only meet the needs of multiple grounding electrodes and connections between grounding electrodes and other grounding networks, but also has a position limiting function for the grounding electrode inserted into the central cavity 21. This means that during installation, the user does not need to measure the specific length of the grounding electrode, but simply inserts the grounding electrode directly into the central cavity 21 until it contacts the main structure 1. This ensures that the length of all grounding electrodes protruding from the connector 2 remains consistent, greatly improving the convenience of installation.

[0045] 3. Convenient installation and maintenance: Welding connections require specialized equipment and technicians, making operations difficult in remote areas or harsh construction sites, and disassembly and replacement are difficult after welding. While bolted connections are easy to disassemble, they require regular checks and tightening, increasing maintenance costs and workload. Crimping, on the other hand, is simple and quick to install, requiring no specialized welding equipment or technicians, and is easy to disassemble and replace, facilitating maintenance and modifications to the grounding system.

[0046] 4. Better adaptability: By changing the shape of the main structure 1 and the number of connection terminals 11, it is possible to match different numbers of grounding electrode connections, and at the same time, it can better adapt to various terrains and geological conditions, thereby improving the overall performance of the grounding system.

[0047] The above is Embodiment 1 of the novel grounding grid connector provided in this application. The following is Embodiment 2 of the novel grounding grid connector provided in this application. Please refer to the following for details. Figures 1 to 2 .

[0048] Based on the solution of Embodiment 1 above:

[0049] Furthermore, in the design of the crimping fit between connector 2 and the grounding electrode, a crimping tube structure is adopted for connector 2, which features a specially designed first crimping part 22. This design allows the grounding electrode to achieve seamless contact with the first crimping part 22, thereby further strengthening the connection strength and electrical continuity between the grounding electrode and connector 2. This design ensures that current can flow smoothly through the connection point, effectively reducing energy loss and significantly lowering the probability of safety hazards. In addition, the shape and size of the first crimping part 22 are customizable and can be adjusted according to the specific specifications and usage requirements of the grounding electrode to achieve the best fit and optimal connection performance.

[0050] The grounding electrode is crimped to connector 2. The specific steps are as follows:

[0051] 1. First, carefully mark the crimping area at the designated location on the grounding electrode, ensuring the markings are clear and accurate. Then, insert the grounding electrode into connector 2, ensuring a tight and accurate fit between the connector and the grounding electrode.

[0052] 2. Next, place the connector 2, with the grounding electrode already installed, in the appropriate position on the hydraulic crimping tool, and select a suitable crimping die that matches connector 2. Once preparation is complete, start the hydraulic crimping tool and begin the crimping operation. During the crimping process, ensure that the cylinder of the hydraulic crimping tool remains vertical and stable, avoiding any shaking or tilting. Simultaneously, carefully inspect the pipelines on both sides to ensure they are straight, guaranteeing the quality and safety of the crimping.

[0053] After the crimping is completed, the crimping area forms the first crimping part 22, which is in seamless and tight contact with the grounding body.

[0054] Furthermore, the main structure 1 is a solid structure. Through its meticulously designed solid structure, the robustness and durability of the main structure 1 are significantly enhanced, enabling it to better withstand various mechanical stresses and environmental pressures. This enhanced structural stability ensures the grounding grid connector can operate stably for extended periods, unaffected by external factors. In addition, the solid structure design simplifies the manufacturing process, reducing production costs and enhancing the product's market competitiveness, allowing it to stand out in a fiercely competitive market.

[0055] Furthermore, connector 2 is integrally connected to the main structure 1. This unique integral connection design not only significantly enhances the connection strength between connector 2 and the main structure 1, but also ensures the stability of their electrical continuity, thereby further improving the overall performance of the grounding grid connector. The integral connection can be achieved through various processes such as casting, forging, or integral molding, and the specific process chosen depends on the characteristics of the materials used and the specific requirements of the production process.

[0056] Furthermore, in addition to the integral connection method, the connector 2 and the main structure 1 can also be threaded; specifically, the connecting end 11 is provided with an external thread structure, and one end of the connector 2 is provided with an internal thread structure that is threadedly connected to the external thread structure.

[0057] This threaded connection design offers greater flexibility and convenience, making the connection between connector 2 and main structure 1 more robust and reliable. Simultaneously, the threaded connection facilitates disassembly and replacement, making maintenance and modification of the grounding grid connector easier. Furthermore, the combination of external and internal threads effectively prevents moisture and dust from entering the connection, improving the connector's waterproof and dustproof performance and extending its service life.

[0058] Furthermore, of course, the connector 2 and the main structure 1 can also be crimped; specifically, the connector 2 is provided with a second crimping part, and the connecting end 11 is in seamless contact with the second crimping part.

[0059] This crimping design further enhances the connection strength and electrical continuity between connector 2 and the main structure 1, ensuring stable and efficient current flow and improving the overall performance and safety of the grounding grid connector. The shape and size of the second crimping part can also be customized according to the specific specifications and requirements of the main structure 1 to achieve optimal fit and connection performance. During the crimping process, it is necessary to ensure accurate alignment between connector 2 and the main structure 1, and to use appropriate crimping tools to ensure crimping quality and connection strength.

[0060] Furthermore, the main structure 1 and the connecting parts 2 are made of aluminum alloy.

[0061] Aluminum alloys, with their low density, high strength, good corrosion resistance, and excellent electrical conductivity, are ideally suited for manufacturing grounding grid connectors. This material not only effectively reduces the weight of the connector, improving its portability and installation efficiency, but also ensures long-term stable operation in harsh environments, extending its service life. Furthermore, aluminum alloys possess good processing performance and plasticity, facilitating various forming and processing operations to meet diverse production needs. Specifically, 6063 aluminum alloy can be selected. After heat treatment and strengthening, this alloy exhibits high impact toughness and is not sensitive to notches, ensuring stable connections under various operating conditions and guaranteeing the safe operation of the grounding system. Of course, it is not limited to 6063 alloy; other aluminum alloys can also be used. Those skilled in the art can modify the design according to actual needs without limitation.

[0062] Furthermore, connector 2 is a hollow tube structure, which can be a square tube or a round tube.

[0063] The hollow tube structure is designed to facilitate the insertion and installation of the grounding electrode. Square and circular tubes are common hollow tube structural forms, each with its own unique advantages. Square tubes are more stable and can withstand greater lateral pressure, while circular tubes offer better hydrodynamic performance and reduce fluid resistance. The specific shape of the connector chosen depends on the actual application scenario and requirements.

[0064] Furthermore, the outer surfaces of the connector 2 and the main structure 1 are provided with an aluminum oxide film.

[0065] Alumina film is renowned for its superior corrosion and abrasion resistance, providing a robust protective layer for connector 2 and main body structure 1. This effectively resists environmental erosion and wear, significantly extending the connector's lifespan. Furthermore, this alumina film possesses excellent insulation properties, ensuring the safety and reliability of the connector during electrical connections. The alumina film can be prepared using various processes, such as anodizing, with the specific process determined by the material properties and production requirements. Besides anodizing, other surface treatments, such as electroplating and electroless plating, can further enhance the corrosion and abrasion resistance of the main body structure 1. Additionally, to further improve performance, coatings using other materials, such as epoxy resin and polyurethane, can also be considered. These materials also provide an additional protective layer to withstand more demanding operating environments.

[0066] Furthermore, a tin or silver layer is provided inside the central cavity 21. Both tin and silver layers possess excellent conductivity, effectively reducing contact resistance and thus improving current transmission efficiency. These two materials not only exhibit superior conductivity but also demonstrate excellent oxidation and corrosion resistance, which helps prevent degradation of electrical connection performance inside the central cavity 21 due to oxidation or corrosion. The choice between a tin or silver layer typically depends on the specific application environment and requirements, allowing users to make a flexible selection based on actual usage. During the preparation of these layers, various techniques such as electroplating, electroless plating, or sputtering can be used to uniformly coat the tin or silver layer onto the inner wall of the central cavity 21, ensuring excellent electrical connection performance and corrosion resistance.

[0067] The above provides a detailed description of the novel grounding grid connector provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
