Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Figure 1 This diagram shows a first structural schematic of the connecting and receiving component in this utility model. Figure 2 This shows a first exploded view of the connecting and receiving component in this invention. Figure 3 This diagram shows a second structural schematic of the connecting and receiving component in this invention. Figure 4 This diagram shows a second structural schematic of the connecting and receiving component in this invention. Figure 5A cross-sectional view of the connecting and receiving component of this utility model is shown. The connecting and receiving component includes a copper connecting part 1 and a fixing part 2. One end face of the copper connecting part 1 has a first receiving hole 11, and the other end face of the copper connecting part 1 has a second receiving hole 12. The center of the first receiving hole 11 and the center of the second receiving hole 12 are located on the same axis. The fixing part 2 has a connecting hole 21 and forms a hollow cylinder based on the connecting hole 21. The end of the fixing part 2 away from the copper connecting part 1 has a welding area. The welding area covers the end face of the fixing part 2 away from the copper connecting part 1 and the side wall near the end face, ensuring sufficient welding area for the fixing part 2 to be welded to the gas box 4. The copper connecting part 1 is inserted into the fixing part 2 based on the connecting hole 21 to facilitate a stable connection between the parts inside the gas box 4 and the copper connecting part. In this embodiment, the first receiving hole 11 is used to connect with the inner and outer copper busbars in the high-voltage switchgear. One end of the copper connecting part 1 contacts the copper busbar, and the copper busbar and the copper connecting part 1 are locked together by bolts, thereby strengthening the connection between them. The second receiving hole 12 is used to connect with the gas box 4 in the high-voltage switchgear. The other end of the copper connecting part 1 is also locked to the corresponding part in the gas box 4 by bolts, further strengthening the connection between the gas box 4 and the copper connecting part 1, ensuring that the gas box 4 and the copper busbar remain connected during use. The fixing part 2 is used to fix the copper connecting part 1 in the connecting hole 21 to limit the range of motion of the copper connecting part 1, preventing it from loosening or shifting under stress, thus ensuring the stable operation of the entire high-voltage switchgear.

[0027] Furthermore, copper is an excellent conductive material, which effectively reduces contact resistance and thus reduces power loss, ensuring stable current transmission. This ensures that the two isolated cavities in the high-voltage cabinet are electrically connected through the copper connection part 1, guaranteeing their operational stability.

[0028] It should be noted that in this embodiment, the first receiving hole 11 and the second receiving hole 12 may or may not be connected. When the first receiving hole 11 and the second receiving hole 12 are not connected, the copper busbar transmits current to the copper connecting part 1, and then transmits current to the structure corresponding to the gas box 4 through the copper connecting part 1. The copper connecting part 1 is used as a relay to ensure stable current transmission. When the first receiving hole 11 and the second receiving hole 12 are connected, the connection strength between the first receiving hole 11 and the bolt and the connection strength between the second receiving hole 12 and the gas box 4 are increased. In addition, the bolt and the corresponding component of the gas box 4 are in direct contact, reducing contact resistance.

[0029] Furthermore, the copper connecting part 1 includes a connecting cylinder 13 and a connecting frustum 14, wherein the connecting cylinder 13 and the connecting frustum 14 are integrally formed. The integral forming of the connecting cylinder 13 and the connecting frustum 14 reduces the seams and bonding points between them, avoiding stress on either the connecting cylinder 13 or the connecting frustum 14 during use, thereby improving the overall stability and tear resistance of the product and enhancing the structural strength of the copper connecting part 1 during use.

[0030] Furthermore, the first receiving hole 11 is located at the center of the end face of the connecting frustum 14 away from the connecting cylinder 13, and the first receiving hole 11 has a connecting thread. The first receiving hole 11, located at the center of the connecting frustum 14, allows the copper connecting part 1 to distribute force more evenly to various positions when under stress, which helps reduce deformation or damage caused by uneven stress, and improves the load-bearing capacity and service life of the copper connecting part 1. The first receiving hole 11 has a corresponding connecting thread, and a bolt is correspondingly provided on the copper busbar. The copper busbar is threadedly connected to the first receiving hole 11 by the bolt to achieve a fixed connection between the copper busbar and the connecting receiving part. This connection method provides high connection strength and stability. Moreover, the first receiving hole 11 can withstand large tensile, compressive, and shear forces, preventing the copper connecting part 1 from loosening or falling off due to stress during use, which helps improve connection strength.

[0031] Furthermore, the second receiving hole 12 is located at the center of the end face of the connecting cylinder 13 away from the connecting frustum 14, and the second receiving hole 12 has a connecting thread. The second receiving hole 12, located at the center of the connecting hole 21 of the connecting frustum 14, allows the copper connecting part 1 to distribute force more evenly to various positions when under stress, which helps reduce deformation or damage caused by uneven stress, and improves the load-bearing capacity and service life of the copper connecting part 1. The second receiving hole 12 has a corresponding connecting thread, and the air box 4 is provided with bolts corresponding to the connecting receiving part. The bolts are threaded into the second receiving hole 12 to achieve a fixed connection between the air box 4 and the connecting receiving part, which helps improve the connection strength and stability between the air box 4 and the connecting receiving part. Moreover, the second receiving hole 12 can withstand large tensile, compressive, and shear forces, preventing the copper connecting part 1 from loosening or falling off due to stress during use, thus improving the connection strength.

[0032] Furthermore, the edge of the connecting frustum 14 away from the connecting cylinder 13 is recessed to form multiple locking slots 15. These locking slots 15 provide leverage points for the connecting frustum 14, facilitating disassembly or tightening by operators using tools. When the edge of the connecting frustum 14 has two or more locking slots 15, two independent locking points are provided, increasing the stability and reliability of the connection. When the edge of the connecting frustum 14 has four or six locking slots 15, multiple independent locking points are provided, allowing operators to adjust the direction of action according to the usage scenario.

[0033] Furthermore, the plurality of snap-fit ​​slots 15 are symmetrically distributed based on the center of the connecting frustum 14. In this embodiment, two snap-fit ​​slots are symmetrically distributed based on the center of the connecting frustum 14. The two snap-fit ​​slots provide a force point, facilitating the application of force to the copper connector 1 from two directions, with the two forces acting in opposite directions. The connecting frustum 14 can rotate at a relatively fast speed, improving the efficiency of the installation or disassembly of the copper connector 1. When the snap-fit ​​slots 15 are used in conjunction with the installation and disassembly tools, it ensures that the connecting frustum 14 is subjected to uniform pressure distribution, which helps to reduce stress concentration and potential damage risks, and is beneficial to extending the service life of the copper connector 1.

[0034] Furthermore, one end face of the fixing part 2 near the copper connecting part is recessed to form an annular groove 22. The annular groove 22 is used to securely fix the object in the annular groove 22, enhancing the stability of the fixation and the convenience of assembly. Secondly, the inner wall of the annular groove 22 is polished, increasing the surface smoothness, reducing wear between the object installed in the annular groove 22 and the annular groove 22, and extending its service life.

[0035] It should be noted that the centers of the annular groove, the fixing part, and the connecting hole are located on the same axis, ensuring that the connecting part can be precisely aligned when assembled into the connecting hole, which helps to reduce assembly errors and improve the stability and reliability of the entire system.

[0036] Furthermore, a sealing ring 3 is provided within the annular groove 22. The sealing ring 3 is used to enhance the sealing performance. When the sealing ring 3 is subjected to external force, it undergoes elastic deformation, increasing the contact area between the sealing ring 3 and the annular groove 22, thereby increasing the sealing area between the copper connecting part 1 and the fixing part 2 and improving its sealing performance.

[0037] Furthermore, the connecting frustum 14 is provided with a plurality of protruding ribs 141 on its end face near the connecting cylinder 13, and the positions of the plurality of protruding ribs 141 correspond to the annular groove 22. In this embodiment, the connecting frustum 14 is provided with one or more protruding ribs 141. When the connecting frustum 14 is provided with one protruding rib 141, the position of the protruding rib 141 corresponds to the annular groove 22, and the protruding rib 141 forms a circumferential protruding rib 141, so that the protruding rib 141 can be inserted into the annular groove 22. That is, after the copper connecting part 1 and the fixing part 2 are locked, the protruding rib 141 exerts a force on the sealing ring 3, causing the sealing ring 3 to be squeezed. The sealing ring 3 is squeezed and deformed to fill the gap between the protruding rib 141 and the annular groove 22, increasing the sealing area of ​​the sealing ring 3, thereby improving its sealing performance. When the connecting frustum 14 is provided with one or more protruding ribs 141, and the multiple protruding ribs 141 are symmetrically distributed on the connecting frustum 14 with the center of the frustum 14 as the reference, the design of multiple protruding ribs 141 can provide more uniform and stable support and fixation. The multiple protruding ribs 141 can act like multiple anchor points to firmly fix the sealing ring 3 in the annular groove 22, effectively reducing the risk of loosening or displacement. In addition, multiple protruding ribs 141 can also distribute stress and reduce the risk of damage caused by excessive pressure on a single protruding rib 141.

[0038] Furthermore, the fixing part 2 is made of stainless steel. Stainless steel can form a dense chromium oxide film when exposed to air or water, thus preventing further oxidation and giving it strong corrosion resistance. This ensures that it maintains its appearance and performance even in humid or corrosive environments. The stainless steel fixing part 2 can be directly welded to the gas box, allowing it to be stably installed in the corresponding position within the gas box. This limits the movement range of the copper connecting part 1, preventing it from shaking and causing poor contact during use, and improving the stability of the entire system.

[0039] In summary, this utility model, by setting a fixing part, fixes the copper connecting part in the connecting hole, thereby limiting the range of motion of the copper connecting part and preventing it from loosening or displacing under force, which helps to ensure the stable operation of the entire high-voltage switchgear. This utility model also uses a copper connector, which reduces contact resistance and thus reduces power loss, ensuring stable current transmission. This ensures that the two isolated cavities in the high-voltage switchgear are electrically connected through the copper connector, guaranteeing the operational stability of the entire power system. Furthermore, the copper connector is provided with a first receiving hole and a second receiving hole, which are locked to the corresponding structure, strengthening the connection between the gas box and the copper connecting part, as well as the connection between the copper connector and the copper busbar, ensuring that the gas box and the copper busbar remain connected during use.

Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
