[0020] 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 in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the protection scope of this utility model.
[0021] like Figures 1-4As shown in the figure, the plug 1 and the socket 2 are included. The plug 1 includes a plug upper cover 7 and a plug lower cover 8. A plug bolt 5, a plug copper busbar 6 and a plug copper ring 9 are provided between the plug upper cover 7 and the plug lower cover 8. The socket 2 includes a socket upper cover 12 and a socket lower cover 14. A socket copper busbar 13, a socket copper ring 11 and a socket nut 10 are provided between the socket upper cover 12 and the socket lower cover 14. A plug plastic insulating sleeve 3 is also provided between the plug upper cover 7 and the plug lower cover 8. The threaded connection section on the plug bolt 5 is located inside the plug plastic insulating sleeve 3, and the front end of the plug plastic insulating sleeve 3 protrudes from the lower surface of the plug lower cover 8. The length of the threaded connection section of the plug bolt 5 is shorter than the length of the plug plastic insulating sleeve 3. A socket plastic insulating sleeve 4 is also provided between the socket upper cover 12 and the socket lower cover 14. The socket plastic insulating sleeve 4 is fitted onto the socket nut 10. The upper end face of the socket plastic insulating sleeve 4 has an extension section 15 for wrapping the upper end face of the socket nut 10.
[0022] By using a plastic insulating sleeve 3 on the plug, it is ensured that the plug 1 cannot touch the plug bolt 5 inside the plug at any angle or position. This is mainly because the length of the plug bolt 5 is shortened, allowing it to be contained within the plastic insulating sleeve 3. The front end of the plastic insulating sleeve 3 protrudes from the lower surface of the plug cover 8. The length of the plug bolt 5 allows for a good connection with the socket nut 10, while also preventing contact and ensuring safety. Figure 5 As shown.
[0023] By incorporating a plastic insulating sleeve 4 into the socket, it is ensured that the socket 2 cannot touch the inner wall of the socket nut 10 at any angle or position. This is primarily because the upper end of the plastic insulating sleeve 4 has an extension 15 for wrapping around the upper end of the socket nut 10. This structure prevents contact with the inner wall of the socket nut 10 at any angle or position, ensuring safety. Figure 6 As shown.
[0024] Plug installation steps:
[0025] The plug upper cover 7 and the plug lower cover 8 are connected by a snap-fit mechanism. The plastic insulating sleeve 3, plug bolt 5, plug copper ring 9, and plug copper busbar 6 are located between the plug upper cover 7 and the plug lower cover 8. First, the plug copper busbar 6 and the plug copper ring 9 are riveted together. At the same time, the plug copper busbar 6 and the plug copper ring 9 are high-frequency welded together by welding wire. Next, the plastic insulating sleeve 3 is inserted into the plug copper ring 9 from top to bottom. The plug copper ring 9 limits the movement. Then, the plug bolt 5 is inserted into the plastic insulating sleeve 3. The plug plastic insulating sleeve 3 and the plug copper busbar 6 are fitted with a clearance fit. Finally, the plug upper cover 7 and the plug lower cover 8 are snap-fitted together.
[0026] Socket installation steps:
[0027] The socket upper cover 12 and the socket lower cover 14 are connected by a snap-fit mechanism. The socket copper busbar 13, the socket nut 10, and the socket plastic insulating sleeve 4 are located between the socket upper cover 12 and the socket lower cover 14 via the socket copper ring 11. First, the socket plastic insulating sleeve 4 is fitted onto the socket nut 10, and the socket copper ring 11 is fitted onto the socket plastic insulating sleeve 4. The socket copper busbar 13 is riveted to the socket nut 10, and the socket plastic insulating sleeve 4 is fixed by the socket copper ring 11. Finally, the socket upper cover 12 and the socket lower cover 14 are snap-fitted together.
[0028] When in use, after the plug 1 is connected to the socket 2, the plug plastic insulating sleeve 3 is fitted onto the socket plastic insulating sleeve 4.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
