Technical Field

[0001] This utility model relates to the field of power equipment, and in particular to a jumper winding structure. Background Technology

[0002] With the increasing demands on winding coils in motors, transformers, and other power equipment, this equipment is widely used for fixing stator cores and installing winding coils. Its main function is to ensure the stator core maintains a stable position during winding, while guaranteeing precise installation of the winding coils, preventing loosening or misalignment, thereby improving the operating efficiency and reliability of power equipment. Through effective clamping and adjustment of the stator core, this equipment reduces instability factors during equipment assembly and improves production efficiency.

[0003] In existing technologies, stator cores often face instability issues when installing winding coils, especially during operation, where the stator core is prone to shifting or loosening, leading to inaccurate or unreliable installation positions of the winding coils. This instability not only affects the performance of electrical equipment but can also cause malfunctions during long-term use. Furthermore, the tendency for winding coils to loosen or shift can result in inaccurate installation processes or even short circuits or electrical faults.

[0004] Therefore, a jump-wrap winding structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a jumper winding structure, which aims to improve the problems of unstable fixation of the stator core and easy loosening of the coil during the installation of the winding coil.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a jump-wrap winding structure, including a workbench, a base plate fixedly connected to the top of the workbench, a clamping plate two fixedly connected to the top of the base plate, a fixing block fixedly connected to the top of the base plate, a fixing mechanism provided inside the fixing block, a sliding column slidably connected inside the fixing block, a clamping plate one fixedly connected to one end of the sliding column near the clamping plate two, a stator core provided between the clamping plate one and the clamping plate two, a plurality of mounting slots opened on the inner side of the stator core, a reinforcing mechanism provided inside the mounting slots, and a winding coil sleeved inside two adjacent mounting slots;

A sliding groove is provided inside the mounting groove, and a groove corresponding to the protrusions is provided inside the sliding groove. The insulating baffle is slidably connected inside the sliding groove.

[0008] As a further description of the above technical solution:

[0009] The fixing mechanism includes an outer shell, which is fixedly connected inside the fixing block. An inner shell is fixedly connected inside the outer shell. A pin is slidably connected inside the inner shell. A spring is sleeved on the outside of the pin. A U-shaped slot is opened on the outside of the inner shell. A temporary locking component is provided on the outside of the pin.

[0010] As a further description of the above technical solution:

[0011] The temporary locking assembly includes a pad, the middle of which is fixedly connected to the outside of the pin, and a locking block is fixedly connected to the outside of the pad.

[0012] As a further description of the above technical solution:

[0013] The protrusion is engaged inside the groove, and both the first clamp and the second clamp abut against the surface of the stator core.

[0014] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model employs a reinforcement mechanism, in which the protrusion on the outer side of the insulating baffle cooperates with the groove in the sliding groove, achieving efficient fixing and insulation protection. Compared with existing technologies, it avoids the risk of coil loosening or displacement, allowing the winding coil to be more securely fixed within the stator core. Compared to the problems of unstable fixing or poor insulation in traditional structures, this solution provides safer and more reliable protection.

[0024] 2. In this utility model, a fixing mechanism is used to control the distance between clamp plate one and clamp plate two, and a temporary locking component is used to temporarily lock the pin after it is pulled out, which facilitates the movement of the sliding column in the fixing block.

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.

[0035] Reference Figures 1-7 An embodiment of this utility model provides a jumper winding structure, including a workbench 6, a base plate 5 fixedly connected to the top of the workbench 6, a clamping plate 7 fixedly connected to the top of the base plate 5, a fixing block 3 fixedly connected to the top of the base plate 5, a fixing mechanism provided inside the fixing block 3, a sliding column 4 slidably connected inside the fixing block 3, a clamping plate 2 fixedly connected to one end of the sliding column 4 near the clamping plate 7, a stator core 1 provided between the clamping plate 2 and the clamping plate 7, a plurality of mounting slots 8 opened on the inner side of the stator core 1, a reinforcing mechanism provided inside the mounting slots 8, and a winding coil 9 sleeved inside two adjacent mounting slots 8;

[0036] The reinforcement mechanism includes an insulating baffle 10, with multiple protrusions 13 fixedly connected to the outside of the insulating baffle 10. A sliding groove 12 is provided inside the mounting groove 8, and a groove 11 corresponding to the protrusions 13 is provided inside the sliding groove 12. The insulating baffle 10 is slidably connected inside the sliding groove 12, and the protrusions 13 are engaged inside the groove 11. Both the first clamp 2 and the second clamp 7 abut against the surface of the stator core 1.

[0037] The workbench 6 serves as the supporting platform for the entire device, providing stable foundation support. The base plate 5 is fixedly connected to the top of the workbench 6 and is used to install the clamping plate 7 and the fixing block 3, serving as the supporting component of the upper structure. The clamping plate 7 is fixedly installed on the top of the base plate 5 and is used to cooperate with the clamping plate 2 to clamp one side of the stator core 1, ensuring its stability during operation. The fixing block 3 is also fixed to the top of the base plate 5, and its internal fixing mechanism is used to limit and guide the sliding position of the sliding column 4, serving as an adjustment and locking mechanism. The sliding column 4 is slidably connected inside the fixing block 3, and its end near the clamping plate 7 is fixedly connected to the clamping plate 2, allowing it to slide back and forth in the fixing block 3, thereby adjusting the distance between the clamping plate 2 and the clamping plate 7. The clamping plate 2 is connected through the sliding column 4 and, when clamped with the clamping plate 7, is used to fix the other side of the stator core 1, achieving a stable clamping of the stator core 1. The stator core 1 is set on the clamping plate. Between the first plate 2 and the second plate 7, multiple mounting slots 8 are provided on the inner side to accommodate and position the winding coil 9. The mounting slots 8 are located inside the stator core 1 and are structural slots for mounting the winding coil 9, ensuring that the coils are arranged in an orderly and accurate manner. The winding coil 9 is fitted between two adjacent mounting slots 8 to form a jump-wrap winding structure, realizing electromagnetic induction and electrical energy conduction functions. The insulating baffle 10, as a key component of the reinforcement mechanism, is inserted into the slide groove 12 to shield and isolate the winding coil 9, providing both electrical insulation and mechanical fixation. The protrusion 13 is fixedly connected to the outside of the insulating baffle 10 and is used to engage with the groove 11 inside the slide groove 12, serving as a limit and anti-detachment function. The slide groove 12 is opened inside the mounting slot 8, providing an installation channel and guidance for the insulating baffle 10. The groove 11 is opened inside the slide groove 12 and is used to engage with the protrusion 13 to achieve stable locking of the insulating baffle 10.

[0038] Reference Figure 6 and Figure 7 The fixing mechanism includes a housing 15, which is fixedly connected inside the fixing block 3. An inner housing 16 is fixedly connected inside the housing 15. A pin 17 is slidably connected inside the inner housing 16. A spring 18 is sleeved on the outside of the pin 17. A U-shaped slot 14 is opened on the outside of the inner housing 16. A temporary locking component is provided on the outside of the pin 17. A pull ring is fixedly connected to the top of the pin 17. Multiple circular holes 21 are opened on the top of the sliding column 4. The pin 17 is inserted into one of the circular holes 21.

[0039] The outer shell 15 is fixedly connected inside the fixing block 3, serving as the mounting support for the entire fixing mechanism and providing structural support and protection. An inner shell 16 is fixedly connected inside the outer shell 15, providing guidance and sliding space for the pin 17, ensuring stable movement of the pin 17 during operation. The pin 17 is slidably connected inside the inner shell 16, allowing it to be inserted into or removed from the circular hole 21 on the sliding post 4 when needed, thus locking or releasing the position of the sliding post 4. A spring 18 is sleeved on the outside of the pin 17, providing elasticity so that the pin 17 automatically springs back into the circular hole 21 after the pull ring is released. The locking action is completed; a U-shaped slot 14 is provided on the outer side of the inner shell 16, which is used to cooperate with the temporary locking component on the outer side of the pin 17, so that the pin 17 can be temporarily locked in the U-shaped slot 14 when pulled out, so as to achieve temporary positioning and avoid continuous force tightening; a pull ring is fixedly connected to the top of the pin 17, which is used for manual operation of pulling out and rotating the pin 17, so as to facilitate the locking and unlocking action; multiple circular holes 21 are provided on the top of the sliding column 4 for the pin 17 to be inserted, so as to realize the locking of the sliding column 4 in different positions, which is convenient for adjusting the position of the clamping plate 1 2 and the clamping state of the stator core 1.

[0040] Reference Figure 6 and Figure 7 The temporary locking assembly includes a pad 19, which is fixedly connected to the outside of the pin 17 in the middle. A locking block 20 is fixedly connected to the outside of the pad 19, which is slidably connected to the inside of the U-shaped slot 14. The pad 19 is slidably connected to the inside of the inner shell 16. One end of the spring 18 is fixedly connected to the top of the pad 19, and the other end of the spring 18 abuts against the inner top wall of the inner shell 16.

[0041] The pad 19 is fixedly connected to the outside of the pin 17 in the middle, serving as a transitional structure between the pin 17 and the inner shell 16, and bearing the locking block 20 and the spring 18. The locking block 20 is fixedly connected to the outside of the pad 19. The locking block 20 is used to temporarily lock the pin 17 in the pulled-out state by rotating it into the U-shaped slot 14 on the outside of the inner shell 16 after the pin 17 is pulled out, preventing the pin 17 from automatically rebounding. The body of the pad 19 is slidably connected to the inside of the inner shell 16, allowing the pin 17 to move axially within the inner shell 16. One end of the spring 18 is fixedly connected to the top of the pad 19, and the other end abuts against the inner top wall of the inner shell 16, providing elastic force to push the pad 19 and the pin 17 to rebound and insert into the circular hole 21 on the sliding post 4 after the pull ring is released, thus realizing the automatic locking function.

[0042] Working principle: When using this jumper winding structure, first pull the pull ring to pull the pin 17 out of the circular hole 21 on the sliding post 4. Then rotate the pull ring to make the pin 17 rotate inside the inner shell 16, and make the locking block 20 engage in the U-shaped slot 14, thereby temporarily locking the pin 17 inside the inner shell 16 and avoiding the need to continuously pull the pin 17.

[0043] Next, the sliding column 4 can slide freely within the fixed block 3, thereby adjusting the distance between the second clamping plate 7 and the first clamping plate 2. Then, the stator core 1 is placed between the second clamping plate 7 and the first clamping plate 2, so that it contacts the second clamping plate 7. Then, the first clamping plate 2 is moved until its surface is in close contact with the stator core 1.

[0044] Next, gently pull the pull ring to allow the pin 17 to rotate within the inner housing 16. Then, rotate the pin 17 in the opposite direction to allow the locking block 20 to slide within the U-shaped groove 14. Finally, release the pull ring, and under the action of the spring 18, the pin 17 automatically inserts into the circular hole 21 on the sliding post 4, completing the locking of the sliding post 4. At this point, the stator core 1 is securely clamped between the second clamping plate 7 and the first clamping plate 2.

[0045] Subsequently, the winding coil 9 is installed between two adjacent mounting slots 8. After the winding is completed, the insulating baffle 10 is inserted into the slide groove 12, and its outer protrusion 13 is engaged with the groove 11, thereby completing the installation of the insulating baffle 10.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
