Description

Technical Field

[0001] This utility model relates to the field of stator winding technology, and in particular to a stator winding connection structure. Background Technology

[0002] Stator windings are windings installed on the stator, consisting of multiple coils or coil groups. They are the core components used to generate a magnetic field or realize electromechanical energy conversion in a motor. Motors can be divided into two categories: centralized and distributed, depending on the shape of the coil windings and the embedding and wiring method.

[0003] The stator winding needs to be energized by wiring during use. After being energized, the stator winding generates a magnetic field. However, the existing stator winding has certain inconveniences when wiring.

[0004] First, the existing stator windings are energized by connecting the lines with copper sheets. However, when connecting the copper sheets to energize, the connecting lines need to be wound, which is inconvenient to disassemble and assemble during use. In addition, the stability of the winding is poor, and there is no external protection after connection.

[0005] Therefore, we propose a stator winding connection structure. Utility Model Content

[0022] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0023] In order to solve the problems existing in the background art, this application proposes the following technical solution: a stator winding connection structure.

[0024] The specific technical solution includes a stator core 1, a winding structure 2, external wiring 4, and a wiring assembly 5. The wiring assembly 5 includes a first housing 501, a second housing 502, a wire-passing end 503, a carrier plate 504, a connecting rod 505, a connecting hole 506, a limiting hole 507, a first spring 508, a contraction groove 509, a limiting block 510, and a second spring 511. The second housing 502 is located on one side of the first housing 501. The wire-passing ends 503 are all located on the outer surfaces of both ends of the first housing 501 and the second housing 502. The carrier plates 504 are all located in the middle of the first housing 501 and the second housing 502. The connecting rod 505 is fixedly installed on the lower outer surface of the first housing 501. The connecting hole 506 is located on the upper outer surface of the second housing 502. The limiting holes 507 are all opened in the second housing 502. On both outer surfaces of the carrier plate 504, the first spring 508 is fixedly installed on the lower outer surface of the carrier plate 504. The shrinkage groove 509 is located inside the docking rod 505. The limiting block 510 is located in the middle of the shrinkage groove 509. The second spring 511 is installed between the limiting block 510 and the shrinkage groove 509. When in use, the wiring assembly 5 can fix the first terminal piece 6 and the second terminal piece 7 through the first housing 501 and the second housing 502 respectively. When the first housing 501 and the second housing 502 are closed, the first terminal piece 6 and the second terminal piece 7 can be easily put into contact, so that the external wiring 4 and the winding wiring 3 can be easily connected and energized. When in use, wiring and energizing are convenient and easy to disassemble and assemble. In addition, the first housing 501 and the second housing 502 can provide a sealing and protection effect for the wiring.

[0025] Furthermore, the threading end 503 is integrally formed with the first housing 501 and the second housing 502. The threading end 503 has a semi-circular structure. The carrier plate 504 is movably connected to the first housing 501 and the second housing 502 via the first spring 508. The docking rod 505 and the shrinkage groove 509 are integrally formed. The limiting block 510 is movably connected to the shrinkage groove 509 via the second spring 511. The second housing 502 and the docking hole 506 are integrally formed. The limiting hole 507 and the docking hole 506 are through-holes. When in use, the first housing 501 can hold the first terminal piece 6 on the winding wire 3, and the second housing 502 can hold the second terminal piece 7 on the external wire 4. Then, the first housing 501 can be connected to the docking hole 506 via the docking rod 505. When the limiting block 510 is squeezed, it will move backward and retract into the shrinkage groove 509, compressing the second spring 511. After the docking rod 505 is docked, the limiting block 510 aligns with the limiting hole 507. At this time, the second spring 511 will spring the limiting block 510 into the limiting hole 507 for fixation, thus completing the docking and fixation of the first housing 501 and the second housing 502. At this time, the first terminal piece 6 and the second terminal piece 7 in the first housing 501 and the second housing 502 squeeze the carrier plate 504. At this time, the carrier plate 504 pushes the first terminal piece 6 and the second terminal piece 7 back through the first spring 508, so that the first terminal piece 6 and the second terminal piece 7 can be tightly fitted together. The first housing 501, the second housing 502 and the carrier plate 504 are all made of insulating material, which provides high safety during use.

[0026] Reference Figure 1 As shown, a winding wire 3 is provided on the outer surface of one end of the winding structure 2. A first terminal piece 6 is fixedly connected to the outer surface of one end of the winding wire 3. A second terminal piece 7 is fixedly connected to the outer surface of one end of the external wire 4. When in use, the external wire 4 can be connected to the first terminal piece 6 through the second terminal piece 7. The winding wire 3 can be energized through the second terminal piece 7 and the first terminal piece 6, so that the winding wire 3 transmits power to the winding structure 2, causing the winding structure 2 to generate a magnetic field.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0028] In use, the first housing 501 can be used to place the first terminal piece 6 on the winding connection 3, and the second housing 502 can be used to place the second terminal piece 7 on the external connection 4. Then, the first housing 501 can be connected to the docking hole 506 via the docking rod 505. When the docking rod 505 is docked, the limiting block 510 is squeezed and will move backward and retract into the shrinkage groove 509, compressing the second spring 511. After the docking rod 505 is docked, the limiting block 510 is aligned with the limiting hole 507. At this time, the second spring 511 will push the limiting block... 510 is inserted into the limiting hole 507 for fixation, thereby completing the docking and fixation of the first housing 501 and the second housing 502. At this time, the first terminal piece 6 and the second terminal piece 7 in the first housing 501 and the second housing 502 press against the carrier plate 504. The carrier plate 504 pushes the first terminal piece 6 and the second terminal piece 7 back through the first spring 508, so that the first terminal piece 6 and the second terminal piece 7 can be tightly fitted together. The first housing 501, the second housing 502 and the carrier plate 504 are all made of insulating material, which provides high safety during use.
