Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a side-outlet structure for a stator. Background Technology

[0002] In existing technologies, stator junction boxes in motors or control systems typically need to be connected to the controller, generally using either movable or fixed mounting methods. However, due to differences in the positional requirements of different types of controller terminals, junction boxes often cannot be fixed in a uniform location and must be installed movablely. Existing movable mounting methods, requiring manual operation to assemble the controller and housing, are prone to poor contact, thus reducing the overall reliability of the system. Utility Model Content

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide a side-outlet structure for the stator, which uses a movable adapter to convert the junction box from a movable mode to a fixed mode for installation on the stator, thereby optimizing the reliability of the connection and solving the defect that the junction box can only be installed in a fixed position.

[0004] Technical solution: This utility model discloses a side-outlet structure for a stator, comprising:

[0005] The stator includes an iron core and a lower frame, the lower frame is installed on the lower end face of the iron core, and the outer diameter of the iron core is larger than the outer diameter of the lower frame;

[0006] An adapter, the adapter including a snap-fit ​​portion mounted on the lower frame and a sliding groove portion connected to the snap-fit ​​portion and located radially outside the lower frame, the sliding groove portion being arranged along the axial direction of the lower frame;

[0007] A junction box, comprising a box body and a pin portion integrally formed with the box body, the pin portion being inserted into and connected to the sliding groove portion.

[0008] Furthermore, the buckle portion is a groove, and the inner wall of the buckle portion is an arc surface with the same curvature as the lower skeleton.

[0009] Furthermore, the length of the groove portion does not exceed the axial length of the lower skeleton.

[0010] Furthermore, the outer surface of the iron core is provided with a limiting groove arranged along its axial direction.

[0011] Furthermore, the slide groove also includes a fixing part that extends from one end of the slide groove near the iron core and along the axial direction of the iron core.

[0012] Furthermore, one side of the fixing part facing the outer side of the iron core has a limiting block, which can be accommodated in the limiting groove.

[0013] Furthermore, the side wall of the sliding groove is provided with two opposing protrusions, which limit the position of the pin portion.

[0014] Furthermore, the junction box is also provided with two blocking blocks, which are installed on both sides of the plug portion.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) This utility model uses a movable adapter to change the junction box from a movable mode to a fixed mode for installation on the stator, thereby optimizing the reliability of the connection and solving the defect that the junction box can only be installed in a fixed position.

[0030] like Figures 1 to 6 As shown, this utility model discloses a side-outlet structure for a stator, comprising:

[0031] Stator 1, the stator 1 includes an iron core 11 and a lower frame 12, the lower frame 12 is installed on the lower end face of the iron core 11, and the outer diameter of the iron core 11 is larger than the outer diameter of the lower frame 12;

[0032] The adapter 2 includes a snap-fit ​​part 21 mounted on the lower frame 12 and a sliding groove part 22 connected to the snap-fit ​​part 21 and located on the radially outer side of the lower frame 12. The sliding groove part 22 is arranged along the axial direction of the lower frame 12. The adapter 2 includes at least two working positions on the lower frame 12.

[0033] Junction box 3, the junction box 3 includes a box body 31 and a plug part 32 integrally formed with the box body 31, the plug part 32 being inserted and connected to the sliding groove part 22.

[0034] With the above structure, the adapter 2 is mounted on the annular wall of the lower frame 12 via the snap-fit ​​part 21. The adapter 2 also includes a sliding groove part 22 connected to the snap-fit ​​part 21. After the adapter 2 is connected to the lower frame 12, the sliding groove part 22 is located radially outward of the lower frame 12. The sliding groove of the sliding groove part 22 is arranged along the axial direction of the lower frame 12. The junction box 3 includes a box body 31 and a pin part 32 integrally formed with the box body 31. The pin part 32 can be inserted and connected to the sliding groove part 22 of the adapter 2, thereby fixing the junction box 3 on the lower frame 12 via the adapter 2.

[0035] Specifically, the outer diameter of the stator 1's core 11 is larger than the outer diameter of the lower frame 12, and a step-like structure is formed at the junction of the core 11 and the lower frame 12, providing support for the adapter 2. The adapter 2's snap-fit ​​part 21 and sliding groove part 22 are integrally formed, reducing production and installation difficulty. The sliding groove part 22 extends from the lower frame 12 towards the core 11. The adapter 2 provides a insertion channel for the connector pin part 32 of the junction box 3 through the sliding groove part 22, resulting in a simple and efficient connection. The junction box 3 adopts an integrally formed design for the box body 31 and the connector pin part 32, further enhancing the reliable installation of the junction box 3 and the lower frame 12, and facilitating independent disassembly and assembly of the junction box 3, reducing maintenance complexity.

[0036] like Figure 4 and Figure 5 As shown, in this embodiment, the snap-fit ​​part 21 of the adapter 2 is a groove, and the curvature of the inner sidewall of the snap-fit ​​part 21 is consistent with the curvature of the lower frame 12, which can achieve a tight fit and improve the fixation stability.

[0037] The sliding groove 22 of the adapter 2 does not exceed the axial length of the lower frame 12 to avoid interference between the sliding groove 22 and the lower end face of the iron core 11 during installation. Preferably, the length of the sliding groove 22 is the same as the axial length of the lower frame 12, and the end of the sliding groove 22 near the iron core 11 is in close contact with the lower end face of the iron core 11. The stepped structure formed by the iron core 11 and the lower frame 12 provides support and limit for the sliding groove 22.

[0038] In this embodiment, the sliding groove 22 also includes a fixing part 23, which extends axially along the iron core 11 and has a limiting block 24 on the side near the outer side of the iron core 11. Correspondingly, the outer surface of the iron core 11 also has several limiting grooves 13 arranged axially therein. The limiting block 24 can be accommodated in the limiting grooves 13, so that the adapter 2 and the iron core 11 can be accurately aligned and firmly fixed, further enhancing the shock resistance and stability of the adapter 2. The user can determine the installation position of the adapter 2 through the limiting grooves 13 provided on the iron core 11, and change the installation position of the adapter 2 by selecting different limiting grooves 13.

[0039] like Figures 4 to 6As shown, in this embodiment, the inner wall of the slide groove 22 of the adapter 2 is provided with two protrusions 25. The junction box 3 and the slide groove 22 are limited by the pin 32 and the two opposing protrusions 25 in the slide groove, ensuring that the pin 32 will not loosen or shift within the slide groove 22. At the same time, blocking blocks 33 are provided on both sides of the pin 32 of the junction box 3. Preferably, the blocking blocks 33 can abut against the lower end face of the iron core 11. The blocking blocks 33 prevent the junction box 3 from tilting during installation or disassembly, ensuring the convenience and accuracy of installation.

[0040] like Figure 1 , Figure 3 and Figure 6 As shown, in this embodiment, two blocking blocks 33 on the junction box 3 are respectively installed on both sides of the pin portion 32, cooperating with the structure of the sliding groove portion 22. The blocking blocks 33 extend along the axial direction of the junction box 3, and their positions are located on both sides of the pin portion 32. The design of the blocking blocks 33 allows the pin portion 32 to be restricted by the stepped structure formed by the iron core 11 and the lower frame 12 during the insertion of the sliding groove portion 22, so that the junction box 3 can provide an additional mechanical stop when inserted into place. The setting of the blocking blocks 33 can prevent the pin portion 32 from swaying left and right or tilting axially, ensuring that the pin portion 32 can always maintain a stable posture in the sliding groove portion 22, thereby improving the assembly accuracy of the junction box 3 and the adapter 2.

[0041] In actual use, the lower frame 12 of the stator 1 fits tightly against the iron core 11. The snap-fit ​​part 21 of the adapter 2 adopts an arc-shaped groove and is installed on the annular wall of the lower frame 12 by insertion. The length of the sliding groove part 22 matches the axial length of the lower frame 12, and extends to form a fixing part 23 at one end near the iron core 11. The limiting block 24 on the fixing part 23 is embedded in the limiting groove 13 on the outer side of the iron core 11 to ensure that the sliding groove part 22 and the lower frame 12 are axially aligned. The junction box 3 is inserted into the sliding groove part 22 through the pin part 32. The blocking blocks 33 on both sides of the pin part 32 form a limiting structure with the stepped structure formed by the iron core 11 and the lower frame 12. The protrusion 25 of the sliding groove part 22 cooperates with the pin part 32 to restrict the movement of the pin part 32 and improve the firmness of the installation.

[0042] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. 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.
