Description

Technical Field

[0001] This utility model relates to stators, and more particularly to a frame that improves insulation performance. Background Technology

[0002] As an important component in motor production, the stator typically includes a stator core, a frame, and coil windings. After the frame is installed on the stator core, the coil is wound around the stator core with the frame. Currently, in the market, two frames are usually inserted into the top and bottom of the stator core respectively.

[0003] After the coil in one winding slot is wound, the enameled wire needs to cross to the next winding slot for winding. At this time, the enameled wire needs to extend from the winding slot, pass through the frame, and be set up along the outer periphery of the frame. In order to facilitate the coil to pass through the frame and extend to the outer periphery of the frame, although the existing frame will have notches of various heights, each notch is used not only when the coil is entering the frame, but also when the coil is exiting the frame. Since there is no obstruction between the coil's entry and exit areas, this will affect the insulation effect between the coils and make it impossible to clearly observe the coil's wiring, thus affecting the motor's durability and lifespan. Utility Model Content

[0004] This utility model provides a frame with improved insulation effect, solving the technical problem of poor insulation effect, and provides the following technical solution:

[0005] A frame with improved insulation effect includes a frame body. The upper outer periphery of the frame body is provided with multiple annular grooves. Multiple notches are sequentially provided along the upper part of the frame body in the circumferential direction. Each notch has a vertically arranged boss on the frame body. The characteristic is that the height of each boss is greater than the width of the annular groove. The top outer periphery of the frame body is provided with multiple fourth notches. Each fourth notch extends longitudinally into the third annular groove.

[0006] By adopting the above technical solution, each notch can be divided into two areas. These two areas can isolate the incoming and outgoing lines when setting up three-phase lines, so that one area is used for the incoming line and the other area is used for the outgoing line, thereby increasing the creepage distance between the incoming and outgoing lines and thus increasing the service life of the motor. With the setting of the fourth notch, the state of the coil can be clearly seen when the coil is running along the third annular groove, thereby speeding up the coil running speed and thus speeding up production efficiency.

[0007] Furthermore, the gap includes multiple sets of first gaps, second gaps, and third gaps, wherein the height of the first gap is greater than the height of the second gap, and the height of the second gap is greater than the height of the third gap;

[0008] The protrusion includes a plurality of first protrusions, second protrusions and third protrusions, with the plurality of first protrusions sequentially disposed in the first notch, the plurality of second protrusions sequentially disposed in the second notch, and the plurality of third protrusions sequentially disposed in the third notch.

[0009] By adopting the above technical solution and setting three different heights of notches, the three-phase wires can come out from the notches at different heights and run along the annular groove on the frame body. This can effectively limit the position of the coil, thereby avoiding the displacement of the subsequent coils and improving the aesthetics and neatness of the coil setup.

[0010] Furthermore, the annular groove includes a first annular groove, a second annular groove, and a third annular groove with identical structures, and the first annular groove, the second annular groove, and the third annular groove are arranged sequentially from bottom to top;

[0011] The bottom of the first notch and the lower sidewall of the first annular groove are coincident, the bottom of the second notch and the lower sidewall of the second annular groove are coincident, and the bottom of the third notch and the lower sidewall of the third annular groove are coincident.

[0012] Furthermore, the first spacing is between the two lower sidewalls of both the first and second annular grooves, and the height of the first boss is less than the first spacing value; the second spacing is between the two lower sidewalls of both the second and third annular grooves, and the height of the second boss is less than the second spacing value; the third spacing is between the lower sidewall of the third annular groove and the top of the skeleton body, and the height of the third boss is less than the third spacing value.

[0013] By adopting the above technical solution, and by limiting the height of the first boss and the second boss, it can be ensured that when the coil is set along the second annular groove, the first boss will not affect the coil routing. Similarly, the second boss will not affect the coil routing in the first annular groove, thereby ensuring the normal routing of the coil. The height limitation of the third boss is to avoid making the assembled stator too large, which would result in the motor being too large.

[0014] Furthermore, multiple pressure lines with identical structures are provided along the inner wall surface of the skeleton body. Each pressure line is arranged in the radial direction of the skeleton body. A first groove is provided at the lower part of each pressure line in the radial direction. One end of the first groove extends to the outside of the pressure line and the other end extends to the outside of the skeleton body. A positioning post is provided on the skeleton body corresponding to each first groove, and each positioning post corresponds to the boss.

[0015] By adopting the above technical solution, with each positioning post corresponding to a boss, the pressure part on the frame body is used to press down each pressure part on the stator core, and each wound coil winding will leave a section of coil. At this time, this section of coil can come out from the corresponding notch and be wound along the outer periphery of the frame body. The structure is simple and can speed up production efficiency.

[0016] Furthermore, a plurality of through holes are provided on the skeleton body corresponding to the first annular groove. The plurality of through holes are arranged sequentially along the outer periphery of the skeleton body, and each of the through holes is arranged between two positioning posts.

[0017] In summary, this application has the following beneficial effects:

[0018] 1. Each gap can be divided into two areas. When setting up three-phase lines, these two areas can isolate the incoming and outgoing lines, so that one area is used for the incoming line and the other area is used for the outgoing line, thereby increasing the creepage distance between the incoming and outgoing lines and thus increasing the service life of the motor.

[0019] 2. By setting up notches at three different heights, the three-phase wires can emerge from the notches at different heights and run along the annular grooves on the bobbin body. This can effectively limit the position of the coils, thereby preventing the subsequent displacement of the coils and improving the aesthetics and neatness of the coil setup.

[0020] 3. By limiting the height of the first and second protrusions, it can be ensured that when the coil is set along the second annular groove, the first protrusion will not affect the coil routing. Similarly, the second protrusion will not affect the coil routing in the first annular groove, thus ensuring the normal routing of the coil. The height limitation of the third protrusion is to avoid making the assembled stator too large, thereby causing the motor to be too large.

[0021] 4. By setting the fourth notch, the state of the coil can be clearly seen when the coil is running along the third annular groove, thereby speeding up the coil running speed and thus increasing production efficiency;

[0022] 5. By setting each positioning post to correspond to a boss, the pressure part on the frame body is used to press down each pressure part on the stator core, and each wound coil winding will leave a section of coil. At this time, this section of coil can come out from the corresponding notch and be wound along the outer periphery of the frame body. The structure is simple and can speed up production efficiency.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] In a specific embodiment, reference is made to... Figure 1-4 The skeleton, which improves insulation performance, includes a skeleton body 1. In this embodiment, the skeleton body 1 is an insulating skeleton body for mounting on the stator core. Multiple annular grooves are provided on the upper outer periphery of the skeleton body 1, and multiple notches are sequentially provided along the upper circumference of the skeleton body 1. Each notch corresponds to a vertically arranged boss on the skeleton body 1, and the height of each boss is greater than the width of the annular groove. In this specific embodiment, the width of the annular groove is 'a', as shown in the figure. Figure 2 As shown.

[0031] Each gap can be divided into two areas. When setting up a three-phase line, these two areas can isolate the incoming and outgoing lines, so that one area is used for the incoming line and the other area is used for the outgoing line, thereby increasing the creepage distance between the incoming and outgoing lines and thus increasing the service life of the motor.

[0032] The gap includes multiple sets of first gap 2, second gap 3 and third gap 4. The height of first gap 2 is greater than the height of second gap 3, and the height of second gap 3 is greater than the height of third gap 4.

[0033] The protrusion includes multiple first protrusions 5, second protrusions 6, and third protrusions 7. The multiple first protrusions 5 are sequentially disposed within the first notch 2. In this embodiment, the height of the first protrusion 5 is h1, such as... Figure 2As shown; multiple second protrusions 6 are sequentially arranged within the second notch 3. In this embodiment, the height of the second protrusion 6 is h2, as shown. Figure 3 As shown; multiple third protrusions 7 are sequentially arranged within the third notch 4. In this embodiment, the height of the third protrusion 7 is h3, as shown. Figure 4 As shown, the three phase wires can emerge from the gaps at different heights through the three-level gaps and run along the annular groove on the frame body 1. This can effectively limit the position of the coil, thereby avoiding the displacement of the subsequent coil and improving the aesthetics and neatness of the coil setup.

[0034] The annular groove includes a first annular groove 8, a second annular groove 9, and a third annular groove 10 with the same structure, and the first annular groove 8, the second annular groove 9, and the third annular groove 10 are arranged sequentially from bottom to top.

[0035] The bottom of the first notch 2 and the lower side wall of the first annular groove 8 are aligned; the bottom of the second notch 3 and the lower side wall of the second annular groove 9 are aligned; the bottom of the third notch 4 and the lower side wall of the third annular groove 10 are aligned.

[0036] The first spacing is between the two lower sidewalls of both the first annular groove 8 and the second annular groove 9. The height of the first boss 5 is less than the first spacing. Figure 2 In the diagram, L1 represents the first spacing; the second spacing is between the two lower sidewalls of both the second annular groove 9 and the third annular groove 10; the height of the second boss 6 is less than the second spacing value. Figure 3 In the diagram, L2 represents the first spacing; the third spacing is located between the lower side wall of the third annular groove 10 and the top of the skeleton body 1; the height of the third boss 7 is less than the third spacing value. Figure 4 In the diagram, L3 represents the first spacing. By limiting the height of the first boss 5 and the second boss 6, it can be ensured that when the coil is set along the second annular groove, the first boss 5 will not affect the coil routing. Similarly, the second boss 6 will not affect the coil routing in the third annular groove, thus ensuring the normal routing of the coil. The height limitation of the third boss 7 is to avoid making the assembled stator too large, which would result in the motor being too large.

[0037] The top outer periphery of the skeleton body 1 is provided with multiple fourth notches 11, each of which extends longitudinally into the third annular groove. When the coil is running along the third annular groove, the state of the coil can be clearly seen through the fourth notches 11, thereby speeding up the coil running speed and thus increasing production efficiency.

[0038] Multiple identical pressure wire portions 12 are provided along the inner wall of the skeleton body 1. Each pressure wire portion 12 is arranged in the radial direction of the skeleton body 1. A first groove 13 is provided at the lower part of the radial direction of each pressure wire portion 12. One end of the first groove 13 extends to the outside of the pressure wire portion 12, and the other end of the first groove 13 extends to the outside of the skeleton body 1. A positioning post 14 is provided on the skeleton body 1 corresponding to each first groove 13, and each positioning post 14 corresponds to a boss. Multiple positioning holes are provided on the stator core that correspond to and are adapted to the positioning posts 14 in sequence. The coil is wound after the skeleton body 1 is installed on the stator core. Each wound coil winding will leave a section of coil. At this time, this section of coil can come out from the corresponding notch and be wound along the outer periphery of the skeleton body 1. The structure is simple and can speed up production efficiency.

[0039] Multiple through holes 15 are provided on the skeleton body 1 below the first annular groove. The multiple through holes 15 are arranged sequentially along the outer periphery of the skeleton body 1, and each through hole 15 is located between two positioning posts 14.

[0040] Working principle: The positioning pins 14 on the skeleton body 1 are sequentially snapped into the corresponding positioning holes of the stator core. After the skeleton body 1 is installed, the coil is wound. After the coil is wound, the reserved end of each coil winding is extended from the corresponding first notch 2, second notch 3, or third notch 4. The coil coming out of the first notch 2 runs along the first annular groove, the coil coming out of the second notch 3 runs along the second annular groove, and the coil coming out of the third notch 4 runs along the third annular groove.
