Description

Technical Field

[0001] The utility model relates to the technical field of motors, and in particular to an insert, a stator assembly and a motor. Background Art

[0002] At present, in the related technology, the motor has a power line, an enameled wire and a plug-in piece. The enameled wire is welded to the plug-in piece by resistance welding, and the plug-in piece is inserted into the terminal of the power line.

[0003] However, since the thickness of the plug needs to match the terminal of the power cord, and the plug is formed by stamping a sheet, the thickness of the plug cannot match the enameled wire, thereby reducing the connection strength between the plug and the enameled wire. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0005] To this end, a first aspect of the present invention provides an insert.

[0006] A second aspect of the present invention provides a stator assembly.

[0007] A third aspect of the present invention provides a motor.

[0008] In view of this, the first aspect of the utility model provides a plug-in, which is used for a motor, the motor comprising a power cord and a stator assembly, the plug-in comprising a mounting portion, a plug-in portion and a connecting portion, the plug-in portion is connected to the mounting portion, the terminal of the power cord can be connected to the plug-in portion, the connecting portion is connected to the mounting portion, and the enameled wire of the stator assembly can be connected to the connecting portion; wherein the thickness of the connecting portion is different from the thickness of the mounting portion, and / or the thickness of the connecting portion is different from the thickness of the plug-in portion.

[0009] The present application provides a plug-in, which is used for a motor. The motor includes a power cord and a stator assembly. The plug-in includes a mounting portion, a plug-in portion and a connecting portion. The plug-in portion is connected to the mounting portion, and the terminal of the power cord can be connected to the plug-in portion, so that current can be conducted between the plug-in and the power cord. Since the connecting portion is connected to the mounting portion, and the enameled wire of the stator assembly can be connected to the connecting portion, stable conduction of current in the motor can be achieved. By setting the thickness of the connecting portion to be different from the thickness of the mounting portion, and / or the thickness of the connecting portion to be different from the thickness of the plug-in portion, the thickness of the connecting portion can be made easier to match the enameled wire, and then when the plug-in is connected to the enameled wire, the matching degree of the plug-in and the enameled wire can be improved, and the connection strength of the plug-in connecting portion and the enameled wire can be improved, so that the enameled wire can be prevented from falling off or being squeezed and deformed by force, thereby extending the service life of the enameled wire and the plug-in. The terminal of the power cord can be connected to the plug-in part of the plug, and the connecting part in the plug is connected to the plug-in part through the installation part, so as to complete the conduction between the power cord and the enameled wire through the plug. The thickness of the plug-in part or the installation part in the plug-in is different from that of the connecting part. The thickness of the plug-in part of the plug-in can be adapted to the terminal size of the power cord, and the thickness of the connecting part can be set to be adapted to the wire diameter of the enameled wire. Therefore, while ensuring that the plug-in matches the size of the power cord, the adaptability between the plug-in and the enameled wire can be improved, so that the size of the connecting part of the enameled wire and the plug-in is more consistent, and the connection strength of the connecting part of the enameled wire and the plug-in is improved.

[0010] By setting the thickness of the connecting part in the plug to be different from the thickness of the mounting part or the plug-in part, the connection between the connecting part and the enameled wire can be ensured to be stable, and the pressure on the connecting part during the connection process can be reduced, and the pressure on the enameled wire during the connection process can be reduced. Therefore, when the wire diameter of the enameled wire is small, the probability of the enameled wire being deformed by force can be reduced, and the electrical performance of the motor can be affected by excessive deformation of the enameled wire, the service life of the enameled wire can be extended, and the working stability of the motor can be improved. It can also be achieved that while ensuring the connection strength between the connecting part and the enameled wire, by setting a connecting part with different thicknesses from the plug-in mounting part and the plug-in part, the connection strength between the plug-in and the enameled wire can be improved. When the motor is working, the plug-in can be connected to the enameled wire of the stator assembly, and the plug-in can also be connected to the power line in the motor. Therefore, by setting the plug-in, the current can be stably conducted between the power line and the enameled wire, and the stability of the motor operation can be improved.

[0011] In addition, the insert in the above technical solution provided by the utility model may also have the following additional technical features:

[0012] In some technical solutions of the present utility model, optionally, the thickness of the connecting portion is smaller than the thickness of the mounting portion; and / or the thickness of the connecting portion is smaller than the thickness of the plug-in portion.

[0013] In this technical solution, the thickness of the connecting part is smaller than the thickness of the mounting part. When the connecting part is connected to the enameled wire, the enameled wire is wrapped by the connecting part, and then the connecting part and the enameled wire are welded and fixed by resistance welding. By reducing the thickness of the connecting part, the pressure required for the connecting part can be reduced during resistance welding. While ensuring the strength of the connecting structure, excessive pressure can be avoided to cause the enameled wire to be excessively deformed, thereby reducing the probability of deformation of the enameled wire, improving the electrical performance of the enameled wire, and extending the service life of the enameled wire.

[0014] The thickness of the connection part can also be set to be smaller than the thickness of the plug-in part. When performing resistance welding between the connection part and the enameled wire, the thickness of the connection part can also be reduced to ensure the connection effect while reducing the pressure required for the connection part, thereby reducing the pressure on the enameled wire and reducing the probability of deformation of the enameled wire.

[0015] Furthermore, a press can be provided to apply pressure to the connection portion. After current passes through the enameled wire and the enameled wire is energized, heat is generated on the connection portion through the principle of electromagnetic induction. The connection portion is squeezed by the press to increase the connection strength between the connection portion and the enameled wire.

[0016] Specifically, the connection part can be squeezed by a press to reduce the thickness of the connection part, thereby reducing the pressure required for the connection part during resistance welding. While ensuring the strength of the connection structure, it is possible to avoid excessive pressure causing the enameled wire to be excessively deformed, thereby reducing the probability of deformation of the enameled wire, improving the electrical performance of the enameled wire, and extending the service life of the enameled wire.

[0017] In some technical solutions of the present utility model, optionally, the thickness of the connecting portion is greater than the thickness of the mounting portion; and / or the thickness of the connecting portion is greater than the thickness of the plug-in portion.

[0018] In this technical solution, the thickness of the connecting part is greater than the thickness of the mounting part; and / or the thickness of the connecting part is greater than the thickness of the plug-in part. By setting a thicker connecting part, the strength of the connecting structure between the connecting part and the enameled wire can be improved. When the motor power is large, by setting a connecting part with a thickness greater than the thickness of the mounting part, it is easy to adapt to the enameled wire with a larger wire diameter, and the adaptability of the connecting part can be improved. When resistance welding is performed on the connecting part and the enameled wire, the enameled wire with a thicker wire diameter will generate more heat. By setting a thicker connecting part, poor connection between the connecting part and the enameled wire due to excessive heat concentration can be avoided. While improving the connection efficiency, the strength of the connection structure can also be improved.

[0019] In some technical solutions of the present invention, optionally, the thickness of the connecting portion is greater than or equal to 0.25 mm and less than or equal to 0.8 mm.

[0020] In this technical solution, the thickness of the connecting part is greater than or equal to 0.25 mm and less than or equal to 0.8 mm. Therefore, by limiting the thickness range of the connecting part, the connection strength between the connecting part and the enameled wire can be ensured. At the same time, when the enameled wire and the connecting part are resistance welded, the pressure required for the connecting part is reduced by limiting the thickness range of the connecting part, thereby reducing the risk of deformation of the enameled wire due to stress.

[0021] Furthermore, within the thickness range of 0.25 mm or more and 0.8 mm or less, the connection portion can provide sufficient mechanical strength to ensure a stable connection between the enameled wire and the connection portion during resistance welding. A connection portion that is too thick may require a higher pressure to achieve a good welding effect, while a connection portion of appropriate thickness can achieve high-quality welding at a lower pressure.

[0022] In some technical solutions of the present utility model, optionally, the mounting portion, the plug-in portion and the connecting portion are an integrated sheet metal structure.

[0023] In this technical solution, the mounting part, the plug-in part and the connecting part are an integrated sheet metal structure, which can improve the structural strength of the plug-in, improve stability, and ensure stable conduction of the current in the motor. At the same time, the use of an integrated sheet metal structure for the plug-in can also reduce the production cost of the plug-in and improve the assembly efficiency of the plug-in.

[0024] Specifically, the connecting portion of the insert may be punched by a press machine, thereby changing the thickness of the connecting portion, thereby achieving different thicknesses between the connecting portion and the mounting portion or the plug-in portion.

[0025] In some technical solutions of the utility model, optionally, the connecting part includes a bearing part and a crimping part, the bearing part is connected to the mounting part and is arranged along the radial direction of the stator assembly, the first end of the crimping part is connected to one end of the bearing part away from the mounting part, and the second end of the crimping part extends toward the mounting part; the enameled wire can be passed between the bearing part and the crimping part.

[0026] In this technical solution, the connection part includes a bearing part and a crimping part, the bearing part is connected to the mounting part, and is arranged along the radial direction of the stator assembly, the first end of the crimping part is connected to the end of the bearing part away from the mounting part, and the second end of the crimping part extends toward the mounting part; the enameled wire can be inserted between the bearing part and the crimping part, thereby improving the fixing strength of the enameled wire and making the installation and removal of the enameled wire more convenient. At the same time, this design is also conducive to the heat dissipation and fixation of the enameled wire, and improves the performance and life of the enameled wire.

[0027] The enameled wire can be effectively fixed and crimped in the connection part, improving the electromagnetic performance of the entire stator assembly, thereby improving the operating efficiency and performance of the motor.

[0028] Furthermore, by providing the bearing part and the crimping part, it can adapt to enameled wires of different specifications and types, and improve the versatility and flexibility of the connection part. This makes it possible to select suitable enameled wires and connection parts for combination according to actual needs during production and maintenance, thereby reducing production costs and maintenance difficulties.

[0029] In some technical solutions of the present utility model, optionally, the crimping portion is arranged obliquely relative to the bearing portion; or the crimping portion and the bearing portion are arranged in parallel.

[0030] In this technical solution, the crimping portion can be tilted relative to the bearing portion. This makes the enameled wire more stable when crimped, reducing the risk of the enameled wire sliding. The tilted design can make the enameled wire more orderly when passing through the connecting portion, which is conducive to improving the arrangement of the enameled wire, reducing interference and crossing between the enameled wires, and thus improving the electromagnetic performance. The contact surface formed between the tilted crimping portion and the enameled wire is larger, which means that under the same pressure, the enameled wire is subjected to less pressure, reducing the risk of damage to the enameled wire due to uneven force.

[0031] The crimping part and the bearing part may also be arranged in parallel. The crimping part and the bearing part arranged in parallel may be manufactured using similar molds or processes, thereby simplifying the production process and improving manufacturing efficiency. Since the crimping part and the bearing part are arranged in parallel, the connection part can be more easily disassembled and installed when maintaining and replacing the enameled wire, reducing maintenance costs and difficulties.

[0032] In some technical solutions of the present utility model, optionally, the bearing portion and the crimping portion have the same thickness.

[0033] In this technical solution, the bearing part and the crimping part have the same thickness. When the connection part and the enameled wire are resistance welded, the same thickness can make the heat generated by the bearing part and the crimping part the same, so that the welding of the connection part and the enameled wire is more uniform, thereby improving the consistency of the welding between the bearing part, the crimping part and the enameled wire.

[0034] In some technical solutions of the present invention, optionally, a surface of the mounting portion close to the connecting portion is a first surface; a surface of the plug-in portion close to the connecting portion is a second surface; and the first surface and the second surface are not coplanar.

[0035] In this technical solution, the surface of the mounting portion close to the connecting portion is the first surface; the surface of the plug-in portion close to the connecting portion is the second surface; the first surface and the second surface are not coplanar, which facilitates connection with the terminal of the power cord through the plug-in portion, thereby improving the assembly efficiency of the plug.

[0036] A second aspect of the utility model provides a stator assembly, comprising an insert as described in any one of the above technical solutions.

[0037] The present application provides a stator assembly, comprising an insert as in any one of the above technical solutions. Therefore, the stator assembly has all the beneficial effects of the insert as in any one of the above technical solutions.

[0038] In some technical solutions of the utility model, optionally, the stator assembly also includes a stator core and an insulating frame, the insulating frame is installed on the stator core, the insulating frame is provided with a wire passing groove, and the enameled wire is arranged in the wire passing groove; the insert is located on one side of the stator core in the axial direction, and the end of the enameled wire is welded to the connecting part.

[0039] In this technical solution, the stator assembly also includes a stator core and an insulating frame, the insulating frame is installed on the stator core, the insulating frame is provided with a wire groove, and the enameled wire is arranged in the wire groove; the insert is located on one side of the stator core in the axial direction, the end of the enameled wire is welded to the connecting part, and the enameled wire is placed in the wire groove of the insulating frame. This structure helps the enameled wire to generate a more uniform and efficient magnetic field when powered on. This design can reduce the loss of magnetic field and improve the electromagnetic efficiency of the motor. The enameled wire is fixed to the connecting part by welding, which enhances the connection strength between the enameled wire and the stator core and improves the structural stability of the entire stator assembly. At the same time, the presence of the insert can further stabilize the position of the enameled wire and prevent it from moving or loosening during use. The enameled wire is placed in the stator core through the wire groove without additional fixing or adjustment steps, which simplifies the production process and improves production efficiency. At the same time, the welding method is also simpler and more efficient.

[0040] In some technical solutions of the present utility model, optionally, the insulating frame is located on one side of the stator core in the axial direction, and the insulating frame is provided with a slot; and the mounting portion is located in the slot.

[0041] In this technical solution, the insulating frame is located on one side of the stator core in the axial direction, and a slot is provided on the insulating frame; the mounting portion is located in the slot to facilitate fixing the insert. At the same time, through the design of the insulating frame, the key components such as the enameled wire and the stator core can be reduced from being affected by pollutants such as moisture, dust, and chemicals in the external environment, thereby improving the reliability and service life of the stator assembly.

[0042] Furthermore, the main function of the insulation frame is to provide electrical isolation and ensure electrical safety between the stator core and the external environment or other components.

[0046] Specifically, the design of the package usually takes into account the impact on electromagnetic performance, such as reducing electromagnetic interference, optimizing magnetic field distribution, etc. This helps to improve the electromagnetic performance of the stator assembly, thereby improving the performance of the entire device.

[0047] Specifically, the packaging component can be made of a material with good thermal stability, which can effectively prevent overheating inside the stator component and improve the thermal stability of the equipment.

DETAILED DESCRIPTION

[0062] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0063] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0064] Refer to the following Figures 1 to 8 The insert sheet 100 , the stator assembly 210 and the motor 200 according to some embodiments of the present invention are described.

[0065] like Figure 1 and Figure 6As shown, in an embodiment of the utility model, a plug 100 is provided, and the plug 100 is used for a motor 200, and the motor 200 includes a power cord 160 and a stator assembly 210, and the plug 100 includes a mounting portion 110, a plug-in portion 120 and a connecting portion 130, the plug-in portion 120 is connected to the mounting portion 110, the terminal 162 of the power cord can be connected to the plug-in portion 120, the connecting portion 130 is connected to the mounting portion 110, and the enameled wire 220 of the stator assembly 210 can be connected to the connecting portion 130; wherein the thickness of the connecting portion 130 is different from the thickness of the mounting portion 110, and / or the thickness of the connecting portion 130 is different from the thickness of the plug-in portion 120.

[0066] The present application provides a plug 100, which is used for a motor 200. The motor 200 includes a power cord 160 and a stator assembly 210. The plug 100 includes a mounting portion 110, a plug-in portion 120, and a connecting portion 130. The plug-in portion 120 is connected to the mounting portion 110, and a terminal 162 of the power cord can be connected to the plug-in portion 120, so that current can be conducted between the plug 100 and the power cord 160. Since the connecting portion 130 is connected to the mounting portion 110, and the enameled wire 220 of the stator assembly 210 can be connected to the connecting portion 130, stable conduction of current in the motor 200 can be achieved. By setting the thickness of the connecting portion 130 to be different from the thickness of the mounting portion 110, and / or the thickness of the connecting portion 130 to be different from the thickness of the plug-in portion 120, the thickness of the connecting portion 130 can be made easier to match the enameled wire 220. Therefore, when the plug-in sheet 100 is connected to the enameled wire 220, the matching degree between the plug-in sheet 100 and the enameled wire 220 can be improved, and the connection strength between the connecting portion 130 of the plug-in sheet 100 and the enameled wire 220 can be improved, so that the enameled wire 220 can be prevented from falling off or being deformed by force, thereby extending the service life of the enameled wire 220 and the plug-in sheet 100. The terminal 162 of the power cord can be connected to the plug-in portion 120 of the plug 100, and the connecting portion 130 in the plug 100 is connected to the plug-in portion 120 through the mounting portion 110, thereby completing the conduction between the power cord 160 and the enameled wire 220 through the plug 100. By having different thicknesses between the plug-in portion 120 or the mounting portion 110 and the connecting portion 130 in the plug 100, the thickness of the plug-in portion 120 of the plug 100 can be adapted to the size of the terminal 162 of the power cord, and the thickness of the connecting portion 130 can be adapted to the wire diameter of the enameled wire 220, thereby ensuring that the plug 100 matches the size of the power cord 160, and also improving the adaptability between the plug 100 and the enameled wire 220, making the size of the enameled wire 220 and the connecting portion 130 of the plug 100 more consistent, thereby improving the connection strength between the enameled wire 220 and the connecting portion 130 of the plug 100.

[0067] By setting the thickness of the connecting portion 130 in the plug 100 to be different from the thickness of the mounting portion 110 or the plug-in portion 120, the connection between the connecting portion 130 and the enameled wire 220 can be ensured to be stable, and the pressure on the connecting portion 130 during the connection process can be reduced. Therefore, when the wire diameter of the enameled wire 220 is small, the probability of the enameled wire 220 being deformed by force can be reduced, and the electrical performance of the motor 200 can be avoided to be affected by excessive deformation of the enameled wire 220, the service life of the enameled wire 220 can be extended, and the working stability of the motor 200 can be improved. It can also be achieved that while ensuring the connection strength between the connecting portion 130 and the enameled wire 220, by setting the connecting portion 130 with a different thickness from the mounting portion 110 and the plug-in portion 120 of the plug 100, the connection strength between the plug 100 and the power cord 160 can be improved. When the motor 200 is working, the plug 100 can be connected to the enameled wire 220 of the stator assembly 210, and the plug 100 can also be connected to the power cord 160 in the motor 200. Therefore, by setting the plug 100, the current can be stably conducted between the power cord 160 and the enameled wire 220, thereby improving the stability of the operation of the motor 200.

[0068] This embodiment provides an insert 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0069] The thickness of the connecting portion 130 is smaller than the thickness of the mounting portion 110 ; and / or the thickness of the connecting portion 130 is smaller than the thickness of the plug-in portion 120 .

[0070] In this embodiment, the thickness of the connecting portion 130 is less than the thickness of the mounting portion 110. When the connecting portion 130 is connected to the enameled wire 220, the enameled wire 220 is wrapped by the connecting portion 130, and then the connecting portion 130 and the enameled wire 220 are welded and fixed by resistance welding. By reducing the thickness of the connecting portion 130, the pressure required for the connecting portion 130 can be reduced during resistance welding. While ensuring the strength of the connecting structure, excessive pressure can be avoided to cause the enameled wire 220 to be excessively deformed, thereby reducing the deformation probability of the enameled wire 220, improving the electrical performance of the enameled wire 220, and extending the service life of the enameled wire 220.

[0071] The thickness of the connecting portion 130 may also be set to be smaller than the thickness of the plug-in portion 120. When performing resistance welding between the connecting portion 130 and the enameled wire 220, the thickness of the connecting portion 130 may be reduced to ensure the connection effect while reducing the pressure required for the connecting portion 130, thereby reducing the pressure on the enameled wire 220 and further reducing the probability of deformation of the enameled wire 220.

[0072] Furthermore, pressure can be applied to the connection part 130 by setting up a press. After current passes through the enameled wire 220 and the enameled wire 220 is energized, heat is generated on the connection part 130 through the principle of electromagnetic induction. The connection part 130 is squeezed by the press to increase the connection strength between the connection part 130 and the enameled wire 220.

[0073] Specifically, the connection part 130 can be squeezed by a press to reduce the thickness of the connection part 130, thereby reducing the pressure required for the connection part 130 during resistance welding. While ensuring the strength of the connection structure, it is possible to avoid excessive pressure that causes the enameled wire 220 to be excessively deformed, thereby reducing the deformation probability of the enameled wire 220, improving the electrical performance of the enameled wire 220, and extending the service life of the enameled wire 220.

[0074] This embodiment provides an insert 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0075] The thickness of the connecting portion 130 is greater than the thickness of the mounting portion 110 ; and / or the thickness of the connecting portion 130 is greater than the thickness of the plug-in portion 120 .

[0076] In this embodiment, the thickness of the connection part 130 is greater than the thickness of the mounting part 110; and / or the thickness of the connection part 130 is greater than the thickness of the plug-in part 120. By setting the connection part 130 with a larger thickness, the strength of the connection structure between the connection part 130 and the enameled wire 220 can be improved. When the power of the motor 200 is relatively large, by setting the connection part 130 with a thickness greater than the thickness of the mounting part 110, it is convenient to adapt the enameled wire 220 with a larger wire diameter, and the adaptability of the connection part 130 can be improved. When the connection part 130 and the enameled wire 220 are resistance welded, the enameled wire 220 with a thicker wire diameter will generate more heat. By setting the connection part 130 with a larger thickness, it is possible to avoid poor connection between the connection part 130 and the enameled wire 220 due to excessive heat concentration, thereby improving the connection efficiency and the strength of the connection structure.

[0077] This embodiment provides an insert 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0078] The thickness of the connecting portion 130 is greater than or equal to 0.25 mm and less than or equal to 0.8 mm.

[0079] In this embodiment, the thickness of the connecting portion 130 is greater than or equal to 0.25 mm and less than or equal to 0.8 mm. Therefore, by limiting the thickness range of the connecting portion 130, the connection strength between the connecting portion 130 and the enameled wire 220 can be ensured. At the same time, when the enameled wire 220 and the connecting portion 130 are resistance welded, the pressure required for the connecting portion 130 is reduced by limiting the thickness range of the connecting portion 130, thereby reducing the risk of deformation of the enameled wire 220 due to stress.

[0080] Furthermore, within the thickness range of 0.25 mm or more and 0.8 mm or less, the connection portion 130 can provide sufficient mechanical strength to ensure a stable connection between the enameled wire 220 and the connection portion 130 during resistance welding. A connection portion 130 that is too thick may require a higher pressure to achieve a good welding effect, while a connection portion 130 of appropriate thickness can achieve high-quality welding at a lower pressure.

[0081] Specifically, Figure 5 As shown, the thickness of the connecting portion 130 is T2, the thickness T2 of the connecting portion 130 is greater than or equal to 0.25 mm and less than or equal to 0.8 mm, the thickness T2 of the connecting portion 130 can be 0.25 mm, the thickness T2 of the connecting portion 130 can be 0.3 mm, the thickness T2 of the connecting portion 130 can be 0.5 mm, the thickness T2 of the connecting portion 130 can be 0.6 mm, and the thickness T2 of the connecting portion 130 can be 0.8 mm.

[0082] Specifically, when the current of the motor 200 is relatively large, the diameter of the enameled wire 220 used is relatively large, and the connecting portion 130 of the plug 100 is set to different thicknesses from the plug-in portion 120 and the mounting portion 110. The thickness T1 of the plug-in portion 120 and the mounting portion 110 can be set to 0.8 mm, which can match the standard power cord female terminal, and the model of the power cord female terminal can be #187, #205 or #250. At this time, the thickness T2 of the connecting portion 130 can be set to 0.5 mm, so that the connecting portion 130 can provide sufficient mechanical strength to ensure a stable connection between the enameled wire 220 and the connecting portion 130 during resistance welding.

[0083] This embodiment provides an insert 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0084] like Figure 2 As shown, the mounting portion 110 , the plug-in portion 120 and the connecting portion 130 are an integrated sheet metal structure.

[0085] In this embodiment, the mounting portion 110, the plug portion 120 and the connecting portion 130 are an integrated sheet metal structure, which can improve the structural strength of the plug 100, improve stability, and ensure stable conduction of the current in the motor 200. At the same time, the use of an integrated sheet metal structure for the plug 100 can also reduce the production cost of the plug 100 and improve the assembly efficiency of the plug 100.

[0086] Specifically, the connection portion 130 of the insert 100 may be punched by a press machine, thereby changing the thickness of the connection portion 130 to achieve different thicknesses between the connection portion 130 and the mounting portion 110 or the plug-in portion 120 .

[0087] This embodiment provides an insert 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0088] like Figure 3 and Figure 4 As shown, the connecting portion 130 includes a bearing portion 132 and a crimping portion 134. The bearing portion 132 is connected to the mounting portion 110 and is arranged radially along the stator assembly 210. The first end of the crimping portion 134 is connected to an end of the bearing portion 132 away from the mounting portion 110, and the second end of the crimping portion 134 extends toward the mounting portion 110. The enameled wire 220 can be passed between the bearing portion 132 and the crimping portion 134.

[0089] In this embodiment, the connection part 130 includes a bearing part 132 and a crimping part 134. The bearing part 132 is connected to the mounting part 110 and arranged along the radial direction of the stator assembly 210. The first end of the crimping part 134 is connected to one end of the bearing part 132 away from the mounting part 110, and the second end of the crimping part 134 extends toward the mounting part 110. The enameled wire 220 can be inserted between the bearing part 132 and the crimping part 134, thereby improving the fixing strength of the enameled wire 220 and making the installation and removal of the enameled wire 220 more convenient. At the same time, this design is also conducive to the heat dissipation and fixing of the enameled wire 220, and improves the service performance and life of the enameled wire 220.

[0090] Specifically, Figure 7 As shown, the radial direction of the stator assembly 210 is direction F.

[0091] The enameled wire 220 can be effectively fixed and crimped within the connection portion 130 , improving the electromagnetic performance of the entire stator assembly 210 , thereby improving the operating efficiency and performance of the motor 200 .

[0092] Furthermore, by providing the bearing portion 132 and the crimping portion 134, it is possible to adapt to different specifications and types of enameled wires 220, thereby improving the versatility and flexibility of the connecting portion 130. This allows the user to select a suitable combination of enameled wires 220 and connecting portion 130 according to actual needs during production and maintenance, thereby reducing production costs and maintenance difficulties.

[0093] This embodiment provides an insert 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0094] The crimping portion 134 is disposed obliquely relative to the bearing portion 132 ; or the crimping portion 134 and the bearing portion 132 are arranged in parallel.

[0095] In this embodiment, the crimping portion 134 can be tilted relative to the bearing portion 132. This makes the enameled wire 220 more stable when crimped, reducing the risk of the enameled wire 220 sliding. The tilted design can make the enameled wire 220 more orderly when passing through the connecting portion 130, which is conducive to improving the arrangement of the enameled wire 220, reducing interference and crossing between the enameled wires 220, and thus improving the electromagnetic performance. The contact surface formed between the tilted crimping portion 134 and the enameled wire 220 is larger, which means that under the same pressure, the enameled wire 220 is subjected to less pressure, reducing the risk of damage to the enameled wire 220 due to uneven force.

[0096] The crimping portion 134 and the bearing portion 132 may also be arranged in parallel. The crimping portion 134 and the bearing portion 132 arranged in parallel may be manufactured using similar molds or processes, thereby simplifying the production process and improving manufacturing efficiency. Since the crimping portion 134 and the bearing portion 132 are arranged in parallel, when maintaining and replacing the enameled wire 220, the connecting portion 130 may be more easily disassembled and installed, reducing maintenance costs and difficulty.

[0097] This embodiment provides an insert 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0098] The bearing portion 132 and the crimping portion 134 have the same thickness.

[0099] In this embodiment, the bearing portion 132 and the crimping portion 134 have the same thickness. When resistance welding is performed on the connecting portion 130 and the enameled wire 220, the same thickness can make the heat generated by the bearing portion 132 and the crimping portion 134 the same, so that the welding of the connecting portion 130 and the enameled wire 220 is more uniform, thereby improving the consistency of the welding between the bearing portion 132, the crimping portion 134 and the enameled wire 220.

[0100] This embodiment provides an insert 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0101] A surface of the mounting portion 110 close to the connecting portion 130 is a first surface 140 ; ​​a surface of the plug-in portion 120 close to the connecting portion 130 is a second surface 150 ; the first surface 140 and the second surface 150 are not coplanar.

[0102] In this embodiment, the surface of the mounting portion 110 on the side close to the connecting portion 130 is the first surface 140; the surface of the plug-in portion 120 on the side close to the connecting portion 130 is the second surface 150; the first surface 140 and the second surface 150 are not coplanar, which facilitates connection with the terminal 162 of the power cord through the plug-in portion 120, thereby improving the assembly efficiency of the plug 100.

[0103] like Figure 7 As shown, in an embodiment of the present invention, a stator assembly 210 is provided, comprising an insert 100 as in any one of the above embodiments.

This design can reduce the loss of magnetic field and improve the electromagnetic efficiency of the motor 200. The enameled wire 220 is fixed to the connecting portion 130 by welding, which enhances the connection strength between the enameled wire 220 and the stator core 230 and improves the structural stability of the entire stator assembly 210. At the same time, the presence of the insert 100 can further stabilize the position of the enameled wire 220 to prevent it from moving or loosening during use. The enameled wire 220 is directly placed in the stator core 230 through the wire slot 240, without the need for additional fixing or adjustment steps, thus simplifying the production process and improving production efficiency. At the same time, the welding method is also simpler and more efficient.

[0112] Furthermore, the main function of the insulating frame 250 is to provide electrical isolation to ensure electrical safety between the stator core 230 and the external environment or other components, which helps to prevent electrical safety hazards such as leakage and short circuit, and ensure the safety of equipment and operators.
