[0027] like Figure 1 and Figure 2 As shown, this utility model discloses a stator top-out wire structure, comprising:

[0028] Stator 1, the stator 1 includes an iron core 11 and an annular upper frame 12 installed on the upper end face of the iron core 11, and the inner side of the iron core 11 also has winding teeth 13.

[0029] Adapter 2 is detachably connected to the upper frame 12 and is located on the radial inner side of the upper frame 12. Adapter 2 is supported on the winding teeth 13.

[0030] Junction box 3 is snap-fitted to adapter 2.

[0031] With the above structure, the annular upper frame 12 is mounted on the upper end face of the iron core 11 of the stator 1. The upper frame 12 fits tightly against the iron core 11. The adapter 2 is connected to the upper frame 12 and is inserted into the radial inner side of the upper frame 12, supported on the winding teeth 13 of the iron core 11, ensuring its correct installation position and support on the winding teeth 13 to maintain the stability of the overall structure. The junction box 3 is connected to the adapter 2 through a snap-fit ​​mechanism, simplifying the installation process of the junction box 3.

[0032] Specifically, the stator 1 includes an iron core 11 and an upper frame 12. The iron core 11 has a ring-shaped structure, with multiple evenly distributed winding teeth 13 on its inner surface. The winding teeth 13 are used to wind the coil to achieve the electromagnetic function. The iron core 11 is usually made of silicon steel sheet with high magnetic permeability to reduce eddy current losses. The upper frame 12 is fixedly installed on the upper end face of the iron core 11 and also has a ring-shaped structure. The upper frame 12 provides support and fixation for the adapter 2 and the junction box 3. The adapter 2 and the upper frame 12 are detachable components that can cooperate with each other. The adapter 2 is located radially inside the upper frame 12, and its bottom is supported on the winding teeth 13 to ensure structural stability. The shape of the adapter 2 can be designed according to the specific structure of the stator 1. The adapter 2 can be connected to the upper frame 12 by snap-fit, thread, or other detachable connection methods. The junction box 3 is firmly connected to the adapter 2 by a snap-fit ​​structure. The snap-fit ​​provides a strong clamping force and facilitates installation and disassembly.

[0033] In this embodiment, as Figure 3 As shown, the upper frame 12 has three cable tie holes on its annular wall: a first cable tie hole 121, a second cable tie hole 122, and a third cable tie hole 123. The first cable tie hole 121 and the second cable tie hole 122 are located at the lower end of the upper frame 12, and the third cable tie hole 123 is located at the upper end of the upper frame 12, allowing it to be fixed to the adapter 2. Correspondingly, the adapter 2 includes a body 21 and a first positioning hook 22, a second positioning hook 23, and a third positioning hook 24 extending radially outward along the upper frame 12. The first positioning hook 22 extends into the first cable tie hole 121, the second positioning hook 23 extends into the second cable tie hole 122, and the third positioning hook 24 extends into the third cable tie hole 123.

[0034] like Figure 4 and Figure 5As shown, the adapter 2 includes a main body, a first positioning hook 22, a second positioning hook 23, and a third positioning hook 24. The main body provides overall support and connection with the upper frame 12. The first positioning hook 22, the second positioning hook 23, and the third positioning hook 24 extend radially outward along the upper frame 12 to engage with the corresponding first cable tie hole 121, second cable tie hole 122, and third cable tie hole 123, ensuring a stable connection between the adapter 2 and the upper frame 12. Furthermore, the first positioning hook 22 also includes a first extension 221, which extends downward from the main body 21 to enhance the fixing effect of the first positioning hook 22 and provide more stable support for the connection of the first cable tie hole 121. The second positioning hook 23 also includes a second extension 231, which extends downward from the main body 21 to enhance the fixing effect of the second positioning hook 23 and provide more stable support for the connection of the second cable tie hole 122. By using the snap-fit ​​fixing of the positioning hook and the cable tie hole, the connection between the adapter 2 and the upper frame 12 is more secure, reducing the problem of parts loosening or shifting due to vibration or external force, and improving the reliability of the overall structure.

[0035] Preferably, the adapter 2 further includes a first latching part 25, a second latching part 26, and a third latching part 27. The first latching part 25, the second latching part 26, and the third latching part 27 all extend upwards from the body 21 of the adapter 2, are located at the top of the adapter 2, and are arranged at intervals for latching and fixing with the junction box 3. The latching parts can be hook-shaped to provide a strong locking force while facilitating assembly and disassembly. Correspondingly, the junction box 3 includes a first latching hole 31, a second latching hole 32, and a third latching hole 33, which correspond to the first latching part 25, the second latching part 26, and the third latching part 27, respectively, achieving precise positioning and a secure connection. After the latching holes and latching parts are inserted, a self-locking structure is formed, thereby ensuring a stable connection between the junction box 3 and the adapter 2. The adapter 2 and junction box 3 achieve a mechanically self-locking connection through the cooperation of the snap-fit ​​part and snap-fit ​​hole, avoiding the loosening problems that may occur with traditional threaded connections. This ensures stability even under vibration and external forces, guaranteeing connection reliability. Furthermore, the matching design of the snap-fit ​​part and snap-fit ​​hole simplifies the installation process of junction box 3, allowing for quick assembly without additional tools. It also makes maintenance or replacement of junction box 3 more convenient, reducing the complexity and time cost of manual operation.

[0036] In this embodiment, the adapter 2 is further provided with a support portion 211, which optimizes the structural fit between the adapter 2 and the junction box 3. Specifically, the support portion 211 is located at the end of the adapter 2 body 21 that contacts the winding teeth 13, and extends upward along the axial direction of the iron core 11, forming an integrated structure with the adapter 2 body. The support portion 211 can be arc-shaped to provide a stable support surface. The top of the support portion 211 is in direct contact with the junction box 3, providing physical support and ensuring that the junction box 3 can be stably placed on the adapter 2. The support portion 211 provides support for the junction box 3, so that the junction box 3 is not only fixed by the snap-fit, but also bears its own weight and external forces through the support portion 211, preventing the junction box 3 from shaking or shifting during use, and improving the overall structural stability. Preferably, the adapter 2 also includes a protrusion 212 to support the junction box 3. The protrusion 212 is disposed on the upper surface of the adapter body 21. It can be cylindrical, rectangular, or arc-shaped, and the specific shape is determined according to the structural design of the bottom of the junction box 3 to ensure matching and stable support. The protrusion 212 can be single or multiple and distributed at different positions on the upper surface of the body 21. The protrusion 212 provides a stable contact point for the junction box 3, reducing the possibility of the junction box 3 being suspended or tilted, thereby enhancing the stability of the overall structure. Especially during use, the protrusion 212 can effectively distribute the weight and external force of the junction box 3, avoiding uneven stress on the components.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
