[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] This utility model provides the following technical solution:

[0024] As attached Figure 1-6 As shown, this utility model discloses a high-insulation track socket adapter, including an adapter body 1. The adapter body 1 has a plug-in portion 2 and a power-taking portion 3. An inner cavity 4 is formed between the power-taking portion 3 and the plug-in portion 2. A conductive sheet 16 assembly is disposed in the inner cavity 4. The conductive sheet 16 assembly includes a live wire copper sheet 5, a neutral wire copper sheet 6, and a ground wire copper sheet 7. The ground wire copper sheet 7 has a plug-in end 8 and an elastic conductive structure 9. The elastic conductive structure 9 is formed by a protrusion and bend of the plug-in end 8 away from the plug-in portion 2. The elastic conductive structure 9 and the ground wire copper sheet 7 are elastically fitted together. A conductive post 10 is disposed on the elastic conductive structure 9. Specifically, in this design, by providing an elastic conductive structure 9 on the ground wire copper sheet 7, the elastic conductive structure 9 can deform under the action of external force, thereby maintaining good contact with the grounding terminal of the external track socket. When the external force is removed, the elastic conductive structure 9 can return to its original shape, ensuring continuous and stable contact. This design not only improves the electrical connection performance between the adapter and the track socket, but also effectively avoids safety hazards caused by poor contact. In addition, the placement of the conductive post 10 further enhances the electrical connection between the ground copper plate 7 and the external rail socket, improving the insulation performance and safety of the entire adapter.

[0025] Furthermore, the conductive post 10 has a conductive end 27 and a receiving end 28. The conductive end 27 is connected to the elastic conductive structure of the ground copper sheet, and the receiving end 28 extends out of the adapter body. A conductive post body portion 29 is provided between the receiving end 28 and the conductive end 27. The outer diameter of the conductive post body portion 29 is smaller than the outer diameters of the receiving end 28 and the conductive end 27. An insulating sleeve (not shown) is fitted on the conductive post body portion 29. Specifically, in this embodiment, a bracket for fixing the conductive post and the receiving piece is provided on the power taking part 3. A corresponding fixing groove is opened on the bracket 30 for installing the conductive post and the receiving piece. An annular groove 31 is formed between the conductive post body portion 29 of the conductive post and the inner wall of the corresponding fixing groove. An insulating sleeve (which can be an insulating heat-shrinkable film) is fitted in the annular groove. The conductive post body portion 29 is fixed on the bracket by heating and shrinking. At the same time, the setting of the insulating sleeve can improve the insulation performance of the conductive post and further ensure the safety of use. The insulating sleeve on the conductive post body 29 not only effectively isolates current and prevents electrical short circuits, but also protects the conductive post body 29 from external environmental corrosion, thereby extending the service life of the rail socket adapter. Furthermore, the insulating sleeve enhances the insulation performance between the conductive post and the external rail socket, further ensuring safety. The conductive post body 29 has stepped structures at both ends, with annular grooves 31 formed between these steps. The stepped structures increase the electrical clearance between the conductive post and the live and neutral wire contacts, further improving the overall electrical safety performance of the adapter. Simultaneously, the stepped structure facilitates the installation and fixation of the insulating sleeve.

[0026] Furthermore, a grounding slot 11 is formed on the insertion end 8 of the grounding copper sheet 7. The grounding slot 11 has an insertion port 12 away from the elastic conductive structure 9. The elastic conductive structure 9 is formed by bending the grounding copper sheet 7 towards the grounding slot 11, and there is a gap fit between the elastic conductive structure 9 and the opposite side walls of the grounding slot 11. The conductive post 10 is disposed on the end of the elastic conductive structure 9 away from the grounding copper sheet 7. Specifically, in this embodiment, the design of the grounding slot 11 corresponds to the insertion hole position of the insertion part 2 on the adapter body 1, so that the external power connector can be accurately inserted. At the same time, the gap fit between the elastic conductive structure 9 and the side walls of the grounding slot 11 forms a cantilever structure, thereby further enhancing the elastic deformation capability of the elastic conductive structure 9 and ensuring that the conductive post 10 can automatically adjust its position when in contact with the external track socket to achieve the best contact effect. In addition, the gap fit design can also effectively prevent damage to the elastic conductive structure 9 due to excessive external force, improving the durability of the product.

[0027] Furthermore, the elastic conductive structure 9 includes an elastic part 13 and a conductive part 14. The elastic part 13 is connected to the ground copper sheet 7, and both sides of the elastic part 13 are gap-fitted between the two side walls of the ground slot 11. The conductive part 14 is bent at the end of the elastic part 13 away from the ground copper sheet 7, and a conductive connection hole 15 is formed on the conductive part 14. One end of the conductive post 10 extends into the conductive connection hole 15 and connects with the conductive part 14. Specifically, in this embodiment, the separate design of the elastic part 13 and the conductive part 14 allows the elastic part 13 to mainly provide elastic deformation capability, while the conductive part 14 provides conductivity, thus further improving the stability and safety of the adapter. The design of the elastic part 13 ensures that it can maintain excellent elastic deformation capability during long-term use and will not lose elasticity due to fatigue. The design of the conductive connection hole 15 also optimizes the connection between the conductive post 10 and the conductive part 14, reduces contact resistance, and improves conductivity.

[0028] Furthermore, both the live wire copper sheet 5 and the neutral wire copper sheet 6 are composed of corresponding conductive sheets 16 and power-collecting sheets 17. The power-collecting sheets 17 are disposed on both sides of the conductive post 10. Conductive plug-in terminals 18 are formed on the conductive sheets 16, and conductive slots 19 are formed on the conductive plug-in terminals 18. The conductive sheets 16 have positioning parts 20, and power-collecting sheet positioning structures 26 are provided on the positioning parts 20. One end of the power-collecting sheet 17 is connected to the power-collecting sheet positioning structure 26, and the other end of the power-collecting sheet 17 extends out of the inner cavity 4. Specifically, in this embodiment, the design of the live wire copper sheet 5 and the neutral wire copper sheet 6 adopts a combined structure of conductive sheets 16 and power-collecting sheets 17. This design not only simplifies the assembly process but also improves the overall conductivity. The design of the conductive plug-in terminals 18 and conductive slots 19 on the conductive sheets 16 makes the connection with the external power connector more stable and reliable, reducing current fluctuations or interruptions caused by loose connections. Meanwhile, the positioning structure 26 on the positioning part 20 ensures the accuracy of the power-collecting piece 17 during assembly, avoiding the risk of poor contact or short circuit due to positional deviation. The design of the power-collecting piece 17 extending out of the inner cavity 4 facilitates connection with the power cord of external devices or electrical appliances, providing a more flexible power collection method.

[0029] Furthermore, the power-collecting plate positioning structure 26 is a clamping arm protruding from the positioning side. The clamping arm bends towards the positioning part 20, forming a clamping groove 21 between the clamping arm and the positioning part 20. One end of the power-collecting plate 17 extends into the clamping groove 21 and connects with the clamping arm and the positioning part 20. Specifically, in this embodiment, the power-collecting plate positioning structure 26 adopts a combination of clamping arm and clamping groove 21. This design is not only compact but also provides good fixation. The clamping groove 21 formed by the clamping arm bending towards the positioning part 20 provides a stable support and positioning point for the power-collecting plate 17, ensuring that the power-collecting plate 17 will not shift or shake during assembly. At the same time, the cooperation between the clamping arm and the clamping groove 21 also increases the contact area between the power-collecting plate 17 and the positioning part 20, improving the stability and reliability of the connection. This design not only simplifies the assembly process but also improves the overall structural stability, ensuring the safety and stability of the adapter during long-term use.

[0030] Furthermore, the power-collecting piece 17 has a body portion 23, a receiving portion 24, and a positioning connection portion 25. The receiving portion 24 and the positioning connection portion 25 are disposed at both ends of the body portion 23. The positioning connection portion 25 is connected to the power-collecting piece positioning structure 26. The body portion 23 is semi-cylindrical, and a cylindrical structure is formed between the body portions 23 of the power-collecting pieces 17 on the live wire copper sheet 5 and the neutral wire copper sheet 6. The conductive post 10 is located at the center of the cylindrical structure. Specifically, in this embodiment, the body portion 23 is semi-cylindrical, so that the body portions 23 of the two power-collecting pieces 17 form a complete cylindrical structure after assembly. This design not only enhances the structural strength between the power-collecting pieces 17, but also improves the stability and reliability of the connection with external devices or electrical appliance power cords. The conductive post 10 is located at the center of the cylindrical structure. This layout ensures the uniform distribution of current during transmission and reduces the risk of heating or damage caused by current concentration. The power receiving part 24 and the positioning connection part 25 are located at both ends of the main body 23, which not only ensures the realization of the power receiving function, but also ensures the accuracy and firmness of the power receiving piece 17 during the assembly process, further improving the overall performance and safety of the adapter.

[0031] Furthermore, the body portion 23 and the contact portion 24 are arranged in a bent structure. The contact portion 24 is formed by bending the end of the body portion 23 away from the positioning connection portion 25 in a direction away from the central axis of the conductive post 10. The body portion 23 and the contact portion 24 are connected by an arc surface transition. Specifically, in this embodiment, by designing the body portion 23 and the contact portion 24 as a bent structure and using an arc surface transition, the electrical clearance and creepage distance are increased, and machining avoids gaps. This design lengthens the distance between the bent part of the contact piece and the conductive post 10, thereby forming a larger insulation space. During the injection molding process, the molten plastic can better fill this space, forming a more solid insulation layer, further improving the overall insulation performance of the adapter.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
