Description

Technical Field

[0001] The utility model relates to the technical field of motor parts, in particular to a motor stator wire hanging insert. Background Art

[0002] Electric motors, commonly referred to collectively as motors and generators, convert and transmit electrical energy based on the law of electromagnetic induction. By rotating a energized coil in a magnetic field, they convert electrical energy into rotational mechanical energy, thereby driving various mechanical devices such as fans, pumps, and machine tools. Due to their inherent advantages, electric motors are widely used.

[0003] The motor includes a stator and a rotor. The most important component in the motor stator assembly is the motor stator hanging wire piece, also known as the motor stator winding connecting piece. It is mainly used to connect the lead wires of the motor winding to realize current transmission.

[0004] After searching, the Chinese patent announcement number: CN220107698U discloses a DC brushless motor wire-management-free stator assembly, including an upper insulating bracket, a lower insulating bracket, a stator core and an insert. The insert is provided with a bending portion, a first hook and a second hook. The insert and the terminal are combined to form a connection assembly for electrically connecting the stator assembly to the PCB board. The winding method is changed by the insert. When winding, a winding machine is used to directly hang the wire on the insert. There is no need for manual wire management, and wire management is not prone to errors, which improves labor efficiency. The first hook and the second hook are provided on the insert, which can decompose the current and prevent the hook from exploding when spot welding the hook; the insert and the terminal are electrically connected by plugging. When the PCB board is damaged, the PCB board can be easily replaced. However, when replacing the PCB board, the staff needs to release the limit fixation of multiple inserts in turn before the PCB board can be removed. This method is more cumbersome to operate and cannot meet the needs of users. Utility Model Content

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Reference Figure 1 、 Figure 3 and Figure 4The utility model provides an embodiment: a motor stator hanging wire plug-in, including a stator core 1, a plurality of hollow frames 3 are fixedly connected at equal intervals around the top of the stator core 1, a plug-in 4 is slidably connected to the inside of the hollow frame 3, a connecting strip 5 is fixedly connected to one side of the plug-in 4, a limiting rod 7 is fixedly connected to the bottom of the plug-in 4, a fixing plate 6 is fixedly connected to the inner bottom of the hollow frame 3, a limiting slot 9 is provided in the middle of the top of the fixing plate 6, and a plurality of limiting rods 7 are respectively plugged into the corresponding limiting slots 9, and open slots 10 are provided on both sides of the top of the plurality of fixing plates 6, and a rotating shaft 11 is rotatably connected to the inside of the open slot 10, and a support plate 12 is fixedly connected to one side of the rotating shaft 11, and a torsion spring 13 is provided on both sides of the outer wall of the plurality of rotating shafts 11, and one end of the torsion spring 13 is respectively connected to the One side of the corresponding support plate 12 is fixedly connected, and the other end of the torsion spring 13 is fixedly connected to one side of the inner side of the corresponding opening groove 10. The middle and upper parts of the outer sides of the multiple connecting strips 5 are slidably connected to the same movable ring 14. The top of the movable ring 14 is evenly fixedly connected with multiple support columns 8. The bottom of the stator core 1 is provided with a support mechanism 2. The top of the PCB board 15 is evenly fixedly connected with multiple hollow plates 19. The fixed positions of the multiple hollow plates 19 correspond to the opening positions of the through-opening slots 16 respectively. The upper side of the stator core 1 is provided with a PCB board 15. The top of the PCB board 15 is evenly opened with multiple through-opening slots 16. The tops of the multiple connecting strips 5 respectively pass through the corresponding through-opening slots 16. The tops of the multiple support columns 8 are all in contact with the bottom of the PCB board 15.

[0040] Specifically, first press downward on movable ring 14. This compresses torsion spring 13, driving support plate 12 further downward. When support plate 12 is compressed to a certain degree, torsion spring 13 releases its compressive force, causing limit rod 7 to pop out of limit slot 9. Insert 4 then pops out, lifting movable ring 14. At this point, support column 8 at the top of movable ring 14 continues to move upward, freeing PCB 15 from connecting bar 5. This allows both insert 4 and PCB 15 to be removed simultaneously, making removal of both insert 4 and PCB 15 relatively simple.

[0041] Reference Figure 1 and Figure 2 The support mechanism 2 includes an insert block 201, and multiple insert blocks 201 are fixedly connected to the bottom of the stator core 1 at equal intervals. A circular ring 202 is provided on the lower side of the stator core 1. Multiple hollow blocks 203 are fixedly connected to the top of the circular ring 202 at equal intervals. Multiple insert blocks 201 are respectively plugged into the interior of the corresponding hollow blocks 203. Multiple lower end insulating brackets 204 are fixedly connected to the bottom of the circular ring 202 at equal intervals. The sizes of the multiple insert blocks 201 match the internal sizes of the corresponding hollow blocks 203.

[0042] Specifically, the lower insulating bracket 204 is first accurately installed in the predetermined position, and then the insert block 201 is sequentially inserted into each corresponding hollow block 203. This step can effectively enhance the stability of the entire structure, thereby improving not only the practicality of the device but also its reliability and durability in actual application.

[0043] Reference Figure 1 、 Figure 2 and Figure 3 , the inner tops of the multiple inserts 4 are fixedly connected with hooks 20, and both sides of the multiple inserts 4 are provided with card slots 18;

[0044] Specifically, the hook 20 can be used to conveniently hang and wind the cables outside the stator assembly without manual cable management, and cable management is less prone to errors, thereby improving labor efficiency.

[0045] Reference Figure 1 and Figure 2 , multiple limit frames 17 are fixedly connected to the top of the stator core 1, and multiple connecting bars 5 are respectively plugged into the corresponding limit frames 17. The tops of the multiple connecting bars 5 are electrically connected to the external controller;

[0046] Specifically, the limit frame 17 can limit the moving track of the connecting bar 5 so that it can move more smoothly, and the operation of the structure can be controlled by an external controller to facilitate the transmission of current.

[0047] When the PCB board 15 is damaged and needs to be replaced, the support plate 12 is initially in an inclined state and the movable ring 14 is pressed downward. The torsion spring 13 is squeezed and drives the support plate 12 to continue to move downward. When the support plate 12 is squeezed to a certain extent, the torsion spring 13 releases the squeezed force and drives the limit rod 7 to pop out of the limit groove 9, and the plug 4 will also pop out to lift the movable ring 14. At this time, the support column 8 at the top of the movable ring 14 will continue to move upward to make the PCB board 15 separate from the connecting bar 5, and the plug 4 and the PCB board 15 can be removed at the same time. It is relatively simple to disassemble the plug 4 and the PCB board 15, which can meet the needs of users. When using this structure, first install the lower end insulating bracket 204 in the position to be used, and then insert the plug blocks 201 into the corresponding hollow blocks 203 respectively, which can further improve the stability of the structure and will not affect the normal use of the structure, thereby improving the practicality of the device.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
