[0002] In related technologies, during the assembly of a motor, the lead-out terminals of the motor are soldered to the lead wires of the stator coil, and the solder joints are wrapped with insulating sleeves. The wrapped insulating sleeves are then inserted into the stator coil to achieve the connection between the lead-out terminals of the motor and the stator coil. However, this connection process is quite complicated, resulting in low motor assembly efficiency. It also requires a large number of production workers, leading to high manpower costs and high costs in motor assembly. Summary of the Invention

[0062] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0063] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0064] Hereinafter, with reference to the accompanying drawings, a motor device 100 for a compressor according to a first aspect embodiment of the present invention will be described. The motor device 100 may be a distributed winding motor, but is not limited thereto.

[0065] like Figures 1-3 As shown, the motor assembly 100 includes a motor 1 and a wiring assembly 2. The motor 1 includes a stator core 11 and a stator coil 12 disposed on the stator core 11. The wiring assembly 2 includes a wiring bracket 21 and an electrical connector 22. The wiring bracket 21 is fixedly connected to the stator coil 12. At least a portion of the wiring bracket 21 is disposed on the outer peripheral surface of the stator coil 12. Therefore, a portion of the wiring bracket 21 is disposed on the outer peripheral surface of the stator coil 12 (e.g., ...). Figure 2 (as shown), or the entire terminal bracket 21 is disposed on the outer peripheral surface of the stator coil 12, the electrical connector 22 is disposed on the terminal bracket 21, the electrical connector 22 is connected to the stator coil 12 and the electrical connector 22 has a terminal lead-out connection end 220.

[0066] During the assembly of the motor assembly 100, the electrical connector 22 is placed on the terminal bracket 21 and electrically connected to the stator coil 12, for example, the electrical connector 22 is electrically connected to the lead wire 121 of the stator coil 12. This enables the electrical connection between the stator coil 12 and the terminal lead-out connection end 220. The terminal bracket 21 provides insulation protection for the electrical connector 22 to a certain extent. Since the terminal bracket 21 is fixed relative to the stator coil 12, it is not necessary to insert the terminal bracket 21 into the stator coil 12 after the stator coil 12 is connected to the terminal lead-out connection end 220. Compared with some technologies that weld the terminal lead-out connection end to the lead wire of the stator coil and wrap the weld point with an insulating sleeve, this application simplifies the connection process between the terminal lead-out connection end 220 and the stator coil 12, improves the assembly efficiency of the motor assembly 100, and saves manpower and reduces production costs.

[0067] Since at least a portion of the terminal bracket 21 is located on the outer circumferential surface of the stator coil 12, sufficient operating space is provided for the connection between the electrical connector 22 and the stator coil 12, thereby improving connection efficiency. The stator coil 12 can be understood as the portion of the stator coil located at one axial end of the stator core 11.

[0068] Therefore, according to the embodiment of the present invention, the motor device 100 for a compressor, by providing a terminal bracket 21 and an electrical connector 22, and such that at least a portion of the terminal bracket 21 is disposed on the outer peripheral surface of the stator coil 12, and the electrical connector 22 is connected to the stator coil 12, so that the electrical connection between the stator coil 12 and the terminal lead-out connection end 220 is realized through the electrical connector 22, can simplify the connection process between the stator coil 12 and the terminal lead-out connection end 220, improve the assembly efficiency of the motor device 100, and at the same time save manpower and reduce costs.

[0069] In some embodiments, such as Figure 10 As shown, the electrical connector 22 and the stator coil 12 are configured such that during the process of installing the electrical connector 22 onto the terminal bracket 21, the electrical connector 22 is electrically connected to the stator coil 12. In other words, the process of installing the electrical connector 22 onto the terminal bracket 21 and the process of electrically connecting the electrical connector 22 to the stator coil 12 overlap in time. At least part of the above two processes are performed simultaneously, thereby further saving the assembly time of the motor device 100 and improving the assembly efficiency.

[0070] For example, such as Figure 10As shown, the terminal bracket 21 has multiple grooves 2110, and the stator coil 12 has multiple sets of leads 121. Each set of leads 121 is configured corresponding to a groove 2110, and each set of leads 121 is adapted to pass through the corresponding groove 2110 so that a part of the lead 121 is positioned opposite to the insertion port of the groove 2110. At least a part of the electrical connector 22 is inserted into the corresponding groove 2110. During the insertion process, the insert groove 221a on the electrical connector 22 cooperates with the lead 121, and the wall surface of the insert groove 221a scrapes against the outer surface of the lead 121 to peel off the insulation layer of the lead 121, so that the electrical connector 22 is electrically connected to the lead 121.

[0071] As can be seen, during the insertion and installation of the electrical connector 22, the electrical connector 22 achieves electrical connection with the lead wire 121 by piercing the lead wire 121, making the connection process between the electrical connector 22 and the stator coil 12 simple and convenient.

[0072] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the terminal bracket 21 includes a side bracket 211 and an insertion bracket 212. The insertion bracket 212 is connected to the side bracket 211. The side bracket 211 is disposed on the outer peripheral surface of the stator coil 12, and the insertion bracket 212 is disposed between the stator coil 12 and the stator core 11. Thus, the terminal bracket 21 can mate with both the outer peripheral surface of the stator coil 12 and the side of the stator coil 12 facing the stator core 11, which facilitates a reliable mate between the terminal bracket 21 and the stator coil 12 in both the axial and radial directions. At the same time, the assembly and mating of the side bracket 211 and the stator coil 12 will not affect the assembly and mating of the insertion bracket 212 and the stator coil 12, and the assembly and mating of the insertion bracket 212 and the stator coil 12 will not affect the assembly and mating of the side bracket 211 and the stator coil 12, which is beneficial to improving the assembly efficiency of the terminal bracket 21 and the stator coil 12.

[0073] For example, in Figure 2 and Figure 3 In the example, relative to the insertion bracket 212, the side bracket 211 can extend along the axial direction of the stator coil 12, and relative to the side bracket 212, the insertion bracket 212 can extend along the radial direction of the stator coil 12, so that the terminal bracket 21 is roughly formed into an L-shaped structure, which makes the terminal bracket 21 have good structural strength and structural stability. When installing the terminal bracket 21, the insertion bracket 212 can be positioned between the stator coil 12 and the stator core 11, and the terminal bracket 21 can be pushed from the outside to the inside along the radial direction of the stator coil 12 until the side bracket 211 abuts against the outer peripheral surface of the stator coil 12.

[0074] Of course, the terminal bracket 21 may also exclude the insertion bracket 212, so that the entire terminal bracket 21 is set on the outer peripheral surface of the stator coil 12, which also facilitates the assembly of the terminal bracket 21 and the stator coil 12.

[0075] In some embodiments of the present invention, such as Figures 2-4 As shown, the side bracket 211 matches the outer peripheral surface of the stator coil 12, and the inner surface of the side bracket 211 matches the outer peripheral surface of the stator coil 12. The diameter of the inner surface of the side bracket 211 is equal to the diameter of the outer peripheral surface of the stator coil 12, which helps to ensure that the inner surface of the side bracket 211 and the outer peripheral surface of the stator coil 12 are reliably fitted. This helps to increase the contact area between the side bracket 211 and the stator coil 12, thereby ensuring the fitting accuracy between the side bracket 211 and the stator coil 12. This makes the fitting between the side bracket 211 and the stator coil 12 reliable and avoids the side bracket 211 and the stator coil 12 from easily shaking relative to each other, which would affect the operation of the motor device 100.

[0076] In some embodiments of the present invention, the terminal bracket 21 and the stator coil 12 are bundled and fixed. This simplifies the fixing process while ensuring reliable fixation of the terminal bracket 21 and the stator coil 12, making operation easier. Furthermore, during maintenance or other processes, if it is necessary to separate the terminal bracket 21 and the stator coil 12, the bundling material can be cut or untied, allowing for quick separation of the terminal bracket 21 and the stator coil 12, facilitating maintenance. The bundling material can be a binding wire.

[0077] In addition, the binding of the fixed wiring bracket 21 and the stator coil 12 can also bind the stator coil 12 into one unit, ensuring the neatness of the stator coil 12 wire bundle and making the stator coil 12 a whole unit.

[0078] For example, such as Figure 2 and Figure 3 As shown, the side bracket 211 includes a side bracket body 2111 and a side bracket arm 2112. The side bracket arms 2112 are respectively arranged on both sides of the side bracket body 2111. The side bracket arms 2112 are bundled and fixed with the stator coil 12. Since the side bracket arms 2112 are located on the outer circumference of the stator coil 12, the stator coil 12 is roughly formed into a ring structure, which facilitates the bundling and fixing of the wiring bracket 21 and the stator coil 12, so as to quickly realize the bundling and fixing of the entire wiring bracket 21 and the stator coil 12.

[0079] In some embodiments of the present invention, such as Figures 2-6As shown, two side support arms 2112 are symmetrically arranged on both sides of the side support body 2111, and each side support arm 2112 has a binding limiting tooth 2112a on the outer surface opposite to the stator coil 12. The binding member can abut against the surface of the binding limiting tooth 2112a so that the binding limiting tooth 2112a restricts the movement of the binding member, ensures that the binding is firm, and avoids the binding member from shifting and causing the binding to loosen.

[0080] exist Figures 4-6 In the example, two side support arms 2112 are respectively disposed on both sides of the side support body 2111 in the circumferential direction of the stator coil 12. Each side support arm 2112 extends circumferentially along the stator coil 12, and each side support arm 2112 has at least one binding limiting tooth 2112a on its outer surface. The binding limiting tooth 2112a protrudes from the outer surface of the side support arm 2112 and can extend axially along the stator coil 12 to both ends of the side support arm 2112. The binding member has a binding section, which can abut against the side of the binding limiting tooth 2112a facing the side support body 2111, so that the binding limiting tooth 2112a can circumferentially limit the binding section. Of course, the binding section can also abut against the side of the binding limiting tooth 2112a facing away from the side support body 2111.

[0081] Optionally, the side bracket 211 extends into an open ring along the circumference of the stator coil 12, so that the central angle of the side bracket 211 in the circumference of the stator coil 12 is less than 360°; for example, the central angle of the side bracket 211 in the circumference of the stator coil 12 is less than 180°. Under the premise of ensuring reliable installation of the wiring bracket 21, it is beneficial to save the amount of material and weight of the wiring bracket 21.

[0082] It should be noted that, in the description of this application, the circumferential direction of the stator coil 12 is the same as the circumferential direction of the motor device 100, and the axial direction of the stator coil 12 is the same as the axial direction of the motor device 100 (e.g., ...). Figure 1 and Figure 3 (The vertical direction in the middle), the radial direction of the stator coil 12 is the radial direction of the motor device 100.

[0083] It is understandable that the number of binding and limiting teeth 2112a on the two side support arms 2112 can be equal or different. When the number of binding and limiting teeth 2112a on the two side support arms 2112 is equal, the binding and limiting teeth 2112a on the two side support arms 2112 can be arranged symmetrically or asymmetrically. Figure 2 and Figure 6In the example, each side support arm 2112 has n binding limiting teeth 2112a on its outer surface, where n is a positive integer and n≥2. The n binding limiting teeth 2112a are spaced apart circumferentially along the stator coil 12 to improve the binding strength between each side support arm 2112 and the stator coil 12; optionally, n≤3. Of course, each side support arm 2112 may also have only one binding limiting tooth 2112a on its outer surface.

[0084] The protruding direction of the binding limiting teeth 2112a is not specifically limited. For example, the binding limiting teeth 2112a can protrude radially along the stator coil 12 or in a direction parallel to the extension direction of the insertion bracket 212, etc. It is only necessary to ensure that the binding limiting teeth 2112a can limit the binding to prevent the binding from loosening. This application does not specifically limit the binding method of the side bracket arm 2112 and the stator coil 12. It is only necessary to ensure that the side bracket arm 2112 and the stator coil 12 are bound together to achieve fixation.

[0085] In some embodiments of the present invention, such as Figures 4-6 As shown, the inner surface S1 of the side bracket body 2111 and the inner surface S2 of the side bracket arms 2112 on both sides are on the same arc-shaped surface. The arc-shaped surface is in contact with the outer peripheral surface of the stator coil 12, so that the inner surface S1 of the side bracket body 2111 and the inner surface S2 of each side bracket arm 2112 are in contact with the outer peripheral surface of the stator coil 12. This helps to increase the contact area between the side bracket 211 and the stator coil 12, and makes it easier to ensure that the entire side bracket 211 and the outer peripheral surface of the stator coil 12 are reliably in contact. This ensures the fitting accuracy between the side bracket 211 and the stator coil 12, making the fitting between the side bracket 211 and the stator coil 12 reliable, and avoiding the side bracket 211 and the stator coil 12 from easily shaking relative to each other, which would affect the operation of the motor device 100.

[0086] It is understood that the surface defined by the inner surface S1 of the side support body 2111 and the inner surfaces S2 of the side support arms 2112 on both sides is part of the aforementioned arc-shaped surface, and the surface defined by the inner surface S1 of the side support body 2111 and the inner surfaces S2 of the side support arms 2112 on both sides can be a continuous surface or a discontinuous surface.

[0087] In some embodiments of the present invention, such as Figure 4 and Figure 5As shown, the insertion bracket 212 includes an insertion bracket body 2121, which is positioned on one of the stator teeth 111 of the stator core 11. The insertion bracket body 2121 extends in the radial direction of the motor device 100. The insertion bracket body 2121 and one of the stator teeth 111 are arranged opposite each other along the axial direction of the stator coil 12, and the extension direction of the insertion bracket body 2121 and the aforementioned stator tooth 111 are consistent. This ensures that the insertion bracket body 2121 does not cover the two stator slots 112 on both sides of the circumference of the aforementioned stator tooth 111. During the winding process of the stator core 11, the wire does not need to bypass the insertion bracket body 2121, which helps to save the amount of material used in the stator coil and at the same time ensures the winding speed of the stator core 11.

[0088] Furthermore, the insertion bracket body 2121 is configured to correspond to one stator tooth 111, which simplifies the structure of the insertion bracket body 2121 and reduces costs while ensuring the reliable installation of the wiring bracket 21. At the same time, compared to the insertion bracket body 2121 being configured to correspond to multiple stator teeth 111, this application only needs to consider the relative position of the insertion bracket body 2121 and one stator tooth 111, which helps to reduce the processing requirements of the insertion bracket body 2121.

[0089] It is understandable that the stator teeth 111 corresponding to the insertion bracket body 2121 can be reasonably selected from the multiple stator teeth 111 of the stator core 11 according to actual needs.

[0090] For example, if the insertion bracket body 2121 extends radially inward along the motor device 100 such that the inner end face of the insertion bracket body 2121 does not exceed the inner end face of one of the stator teeth 111 in the radial direction of the stator coil 12, then when the rotor of the motor 1 is located inside the stator core 11, it is easy to effectively ensure that the insertion bracket body 2121 will not interfere with the rotation of the rotor, thus ensuring the normal operation of the motor 1. Optionally, if the inner end face of the insertion bracket body 2121 is flush with the inner end face of one of the stator teeth 111, then in the radial direction of the stator coil 12, on the cross-section of the stator coil 12, the outer end of the orthographic projection of the inner end face of the insertion bracket body 2121 is flush with the orthographic projection of the inner end face of one of the stator teeth 111; or, the inner end face of the insertion bracket body 2121 is located outside the inner end face of one of the stator teeth 111 (e.g., Figure 5 As shown), that is, in the radial direction of the stator coil 12, on the cross-section of the stator coil 12, the orthographic projection interval of the inner end face of the insertion bracket body 2121 is located radially outside the orthographic projection of the inner end face of one of the stator teeth 111.

[0091] In some embodiments of the present invention, such as Figure 5As shown, the width of the insertion bracket body 2121 is not greater than the width of one of the stator teeth 111. Therefore, in the circumferential direction of the stator coil 12, the width of the insertion bracket body 2121 at any position is less than or equal to the width at the corresponding position of one of the stator teeth 111. This ensures that the planes on the two sides of one of the stator teeth 111 enclose the insertion bracket body 2121. That is, the portion of the insertion bracket body 2121 corresponding to the stator tooth 111 can be located within the space enclosed by the planes on the two circumferential sides of one of the stator teeth 111. Alternatively, in the cross-section of the stator coil 12, the orthographic projection of the portion of the insertion bracket body 2121 corresponding to the stator tooth 111 in the circumferential direction of the stator coil 12 does not exceed the outer contour of the orthographic projection of one of the stator teeth 111. This effectively ensures that the insertion bracket body 2121 does not cover the stator slot 112 between two adjacent stator teeth 111, ensuring the winding rate of the stator core 11, while also facilitating sufficient routing space for the stator coil in the stator slot 112.

[0092] For example, in Figure 5 In the example, the insertion bracket body 2121 extends radially inward along the motor device 100 such that the inner end face of the insertion bracket body 2121 does not exceed the inner end face of one of the stator teeth 111 in the radial direction of the stator coil 12, and the width of the insertion bracket body 2121 at any position in the circumferential direction of the stator coil 12 is less than or equal to the width at the corresponding position of one of the stator teeth 111. That is, in the cross-section of the stator coil 12, the orthographic projection of the portion of the insertion bracket body 2121 corresponding to the stator tooth 111 does not exceed the outer contour of the orthographic projection of one of the stator teeth 111, whether in the circumferential direction or the radial direction of the stator coil 12.

[0093] In some embodiments, such as Figure 5 and Figure 6 As shown, the two sides of the insertion bracket body 2121 are respectively provided with side flanges 2121a. Insulating paper is provided in the two stator slots 112 adjacent to one of the stator teeth 111. The part of the insulating paper extending out of the corresponding stator slot 112 is folded to form an insulating paper flange. The insulating paper flange presses against the side flange 2121a to position the insertion bracket body 2121, so as to realize the axial positioning of the insertion bracket body 2121 in the stator coil 12.

[0094] It is understandable that when the two sides of the insertion bracket body 2121 are respectively provided with side flanges 2121a, the width of the insertion bracket body 2121 includes the width of the side flanges 2121a.

[0095] exist Figure 5 and Figure 6In the example, the side flange 2121a is located at the end of the corresponding side of the insertion bracket body 2121, axially close to the stator core 11 in the stator coil 12. The insulating paper flange can extend from at least a portion of the edge of the insulating paper in the axial direction of the stator coil 12 toward the direction close to the stator core 11, and the insulating paper flange presses against the side of the side flange 2121a facing away from the stator core 11. Of course, this application is not limited to this; in other embodiments, the side flange 2121a is located at the end of the corresponding side of the insertion bracket body 2121, axially away from the stator core 11 in the stator coil 12. The insulating paper flange can extend from at least a portion of the edge of the insulating paper in the axial direction of the stator coil 12 toward the direction away from the stator core 11, and the insulating paper flange presses against the side of the side flange 2121a facing the stator core 11.

[0096] Optionally, in the radial direction of the stator coil 12, the inner end face of the insulating paper flange is flush with the inner end face of one of the stator teeth 111, or the inner end face of the insulating paper is located radially outside the inner end face of one of the stator teeth 111. In this way, when the rotor of the motor 1 is located inside the stator core 11, it is easy to effectively ensure that the insulating paper flange will not interfere with the rotation of the rotor, and ensure the normal operation of the motor 1.

[0097] Furthermore, such as Figure 6 As shown, the two sides of the insertion bracket body 2121 are respectively provided with stop flanges 2121b. The stop flanges 2121b can be located at the radial inner end of the corresponding side of the insertion bracket body 2121, and the stop flanges 2121b are used to stop the insulating paper flange from extending inward to the inner side of the stator teeth 111, so as to further ensure the normal operation of the motor 1. In the radial direction of the stator coil 12, the insulating paper flange can be arranged at intervals with the stop flanges 2121b, or it can abut against the radial outer side of the stop flanges 2121b.

[0098] It is understandable that the stop flange 2121b and the side flange 2121a located on the same side can be connected or spaced apart.

[0099] Optionally, each stator slot 112 is provided with insulating paper. The length of the insulating paper is greater than the length of the stator slot 112 in the axial direction of the stator coil 12, which helps to ensure the electrical insulation performance of the stator coil 12. At the same time, the thickness of the insulating paper is small, which helps to reduce the proportion of space occupied by the insulating paper in the stator slot 112, so as to free up enough space for the stator coil to run.

[0100] In some embodiments of the present invention, such as Figure 3 and Figure 6As shown, the insertion bracket 212 also includes an insertion bracket connecting part 2122. The insertion bracket connecting part 2122 is used to connect the lower end of the insertion bracket body 2121 and the side bracket 211. The insertion bracket connecting part 2122 extends circumferentially along the stator coil 12, so that the width of the insertion bracket connecting part 2122 is greater than the width of the insertion bracket body 2121 in the circumferential direction of the stator coil 12. This helps to increase the contact area between the insertion bracket 212 and the stator coil 12 in the circumferential direction of the stator coil 12, ensuring stable cooperation between the insertion bracket 212 and the stator coil 12, and preventing the insertion bracket 212 from shaking relative to the stator coil 12.

[0101] Optionally, in the radial direction of the stator coil 12, the length of the insertion bracket 212 is the sum of the length of the insertion bracket body 2121 and the length of the insertion bracket connection portion 2122. The length of the insertion bracket 212 is less than or equal to the difference between the outer diameter and the inner diameter of the stator core 11. The inner diameter of the stator core 11 can be the diameter of the cylindrical surface where the inner end faces of the multiple stator teeth 111 of the stator core 11 are located.

[0102] In some embodiments of the present invention, such as Figure 5 and Figure 6 As shown, the insertion bracket body 2121 is connected to the middle region of the insertion bracket connecting portion 2122, thereby dividing the insertion bracket connecting portion 2122 into two parts by the insertion bracket body 2121. These two parts are located on the circumferential sides of the insertion bracket body 2121, respectively. The inner surface of the insertion bracket connecting portion 2122 of each part is constructed as a concave arc surface 2122a (e.g., a circular arc surface or an elliptical arc surface, etc.). The concave arc surface 2122a is recessed in the direction away from the corresponding stator slot 112. The concave arc surface 2122a is adapted to match the outline of the insulating paper extending from the corresponding stator slot 112, which facilitates the avoidance of the insertion bracket connecting portion 2122 from the insulating paper. At the same time, it is beneficial to achieve a stable fit between the two parts and the corresponding insulating paper, so as to ensure the reliable positioning of the insertion bracket 212 in the circumferential direction of the stator coil 12, and further improve the installation stability of the insertion bracket 212.

[0103] The insertion bracket body 2121 is connected to the middle area of ​​the insertion bracket connecting part 2122. It may be arranged such that the width center line of the insertion bracket body 2121 coincides with the width center line of the insertion bracket connecting part 2122, or is arranged with a small gap. In this way, the circumferential width of the two parts of the insertion bracket connecting part 2122 is not much different, so as to save the overall width and material of the insertion bracket connecting part 2122 while ensuring that the two parts of the insertion bracket connecting part 2122 are respectively set to a stator slot 112.

[0104] For example, each part of the insertion bracket connecting portion 2122 is provided with a stator slot 112. In this case, if we denote one of the stator teeth 111 corresponding to the insertion bracket body 2121 as the selected stator tooth, the two circumferential sides of the selected stator tooth respectively participate in defining a stator slot 112. The two parts of the insertion bracket connecting portion 2122 correspond one-to-one with the two stator slots 112 on the two circumferential sides of the selected stator tooth. Of course, in other embodiments of this application, at least one part of the two parts of the insertion bracket connecting portion 2122 may also be provided with multiple stator slots 112. In this case, the inner surface of the at least one part may be constructed to include multiple concave arc surfaces 2122a, each concave arc surface 2122a matching the outer contour of the corresponding insulating paper.

[0105] In some embodiments of the present invention, such as Figure 3 , Figure 5 and Figure 6 As shown, the side bracket 211 includes a side bracket body 2111, on which multiple grooves 2110 are provided. The stator coil 12 has multiple sets of leads 121, each set of leads 121 corresponding to one groove 2110, which facilitates the allocation of multiple sets of leads 121 and helps to achieve a reasonable and orderly arrangement of multiple sets of leads 121, avoiding wiring chaos. The electrical connector 22 is electrically connected to the corresponding lead 121 to realize the connection between the electrical connector 22 and the stator coil 12. A set of leads 121 may include one or more connecting wires. In the description of this invention, "multiple" means two or more.

[0106] exist Figure 5 In the example, multiple grooves 2110 can be arranged sequentially along the circumference of the stator coil 12. The exit positions of multiple sets of leads 121 can be spaced apart along the circumference of the stator coil 12, ensuring appropriate spacing between adjacent sets of leads 121 and guaranteeing wiring safety. It is understood that the number of grooves 2110 can be greater than or equal to the number of sets of leads 121. For example, the number of grooves 2110 can be 3 to 5, or three, four, or five, to meet the usage requirements of different motors 1 and ensure the applicability of the wiring bracket 21.

[0107] In some embodiments of the present invention, such as Figure 3 , Figures 8-11As shown, the electrical connector 22 includes multiple inserts 221, each insert 221 being inserted into a corresponding groove 2110, facilitating quick installation of the inserts 221. The inserts 221 are electrically connected to the corresponding lead wires 121 within the groove 2110, thus achieving electrical connection between the electrical connector 22 and the corresponding lead wires 121, while also facilitating the fixation of the lead wires 121 within the groove 2110, preventing them from easily shaking or loosening within the groove 2110. The multiple inserts 221 are spaced apart to meet the connection requirements of multiple sets of lead wires 121.

[0108] In some embodiments of the present invention, such as Figures 8-11 As shown, the top of the groove 2110 has an insertion port, and the insert 221 has an insertion slot 221a. The insert 221 is inserted downwards from the insertion port of the groove 2110 to quickly complete the insertion of the insert 221. During the insertion process, the insertion slot 221a scrapes against the lead wire 121 in the groove 2110 to peel off the insulation layer of the lead wire 121, thereby making the insert 221 electrically connected to the lead wire 121. Therefore, before installing the insert 221, the lead wire 121 can be placed in the corresponding groove 2110, and the lead wire 121 can be placed in the groove 2110. A portion of the insert 21 is positioned opposite the insertion port. The insert 221 is inserted from top to bottom, causing the wall of the insert slot 221a to scrape the outer surface of the lead wire 121, removing the insulation layer of the lead wire 121. This allows the wall of the insert slot 221a to directly contact the newly exposed conductive portion of the lead wire 121, achieving electrical connection. Simultaneously, a portion of the lead wire 121 fits within the insert slot 221a; for example, the wall of the insert slot 221a can tightly compress the lead wire 121, facilitating a fixed connection between the lead wire 121 and the insert 221. Therefore, while installing the insert 221, an electrical connection between the insert 221 and the lead wire 121 is also achieved, effectively saving assembly time for the motor device 100 and improving assembly efficiency.

[0109] Optionally, in Figure 11 In the example, at least one of the opposite side walls of the insert slot 221a has a scraping tooth 221b formed on it to effectively ensure that the insert 22 pierces the lead wire 121, so as to achieve a reliable electrical connection between the lead wire 121 and the insert 221. Of course, the wall of the insert slot 221a may not have a scraping tooth 221b formed on it. In this case, the insulation layer of the lead wire 121 can be peeled off by friction between the wall of the insert slot 221a and the lead wire 121.

[0110] Optionally, in Figure 11In the example, the insert 221 includes a first mating portion 2211, a second mating portion 2212, and a connecting portion 2213. The first mating portion 2211 and the second mating portion 2212 are arranged radially spaced along the stator coil 12. Insertion grooves 221a are formed on the first mating portion 2211 and the second mating portion 2212, respectively. The first mating portion 2211 corresponds to the inner wall 2110a of the groove, and the second mating portion 2212 corresponds to the outer wall 2110b of the groove, so that the insertion groove 221a on the first mating portion 2211 is aligned with the inner wall. The through opening R1 is opposite to the insert groove 221a on the second insertion part 2212 and the through opening R2 on the outer wall are opposite to each other; the lower end of the first insertion part 2211 and the lower end of the second insertion part 2212 are connected by the connecting part 2213. The connecting part 2213 has a clearance opening to avoid the insert groove 2210, so that during the insertion process, the lead wire in the groove 2110 can be smoothly inserted into the insert groove 221a of the first insertion part 2211 and the insert groove 221a of the second insertion part 2212 through the clearance opening.

[0111] It is understandable that when the groove 2110 is equipped with a support post 2111B, the avoidance socket can also avoid the support post 2111B to ensure that the insert 221 is installed smoothly.

[0112] Furthermore, in Figure 11 In the example, a stop portion 2214 is provided on the side surface of the first fitting portion 2211 facing the second fitting portion 2212. The stop portion 2214 extends downward from the upper edge of the first fitting portion 2211 toward the second fitting portion 2212 and bends downward. The stop portion 2214 is located above the insert groove 221a. The stop portion 2214 can play a certain limiting and stopping role on the lead wire 121 part that fits in the insert groove 221a, ensuring that the lead wire 121 and the insert 221 are reliably connected and preventing the lead wire 121 from disengaging from the insert 221.

[0113] In some embodiments, such as Figures 5-8 As shown, a separating boss 2111A is provided between adjacent grooves 2110 to ensure effective separation of the inserts 221 in multiple grooves 2110, so that the inserts 221 in adjacent grooves 2110 have sufficient spacing to achieve electrical insulation between the inserts 221 in adjacent grooves 2110, avoid short circuit between multiple sets of leads 121, and at the same time achieve electrical isolation between multiple sets of leads 121 to reduce interference between multiple sets of leads 121.

[0114] For example, in Figure 7In the example, the separating boss 2111A is provided between the insertion openings of adjacent grooves 2110. In the radial direction of the stator coil 12, the length of the separating boss 2111A is greater than or equal to the length of the insertion opening, so as to further effectively separate the electrical connection engagement in adjacent grooves 2110 to avoid short circuit.

[0115] In some embodiments of the present invention, such as Figure 7 and Figure 9 As shown, the width L1 of the separating boss 2111A satisfies the relationship 2mm ≤ L1 ≤ 3mm, for example, the width of the separating boss 2111A is 2mm, or 2.5mm, or 3mm, etc.; and / or, the height L2 of the separating boss 2111A satisfies the relationship 1mm ≤ L2 ≤ 3mm, for example, the height of the separating boss 2111A is 1mm, or 1.6mm, or 2mm, or 2.3mm, or 3mm, etc. Therefore, by reasonably setting the height and / or width of the separating boss 2111A, the effective isolation of the connection of the lead wires 121 in adjacent grooves 2110 is further guaranteed.

[0116] It should be noted that, in the description of this application, "and / or" means that there are three parallel options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0117] In some embodiments, such as Figure 7 , Figure 9 and Figure 10 As shown, the groove 2110 has an inner wall 2110a and an outer wall 2110b. The inner wall 2110a and the outer wall 2110b correspond to each other in the radial direction of the motor device 100. The outer wall 2110b can be located radially outside the inner wall 2110a. An outer wall through-opening R2 is provided on the outer wall 2110b, which can penetrate the outer wall 2110b radially along the stator coil 12. An inner wall through-opening R1 is provided on the inner wall 2110a, which can penetrate the inner wall 2110a radially along the stator coil 12. The outer wall through-opening R2 and the inner wall through-opening R1 correspond to each other in the radial direction of the motor device 100.

[0118] The width of each of the inner wall through opening R1 and the outer wall through opening R2 is greater than the diameter of the lead wire 121, so as to allow the lead wire 121 to pass through. This facilitates the quick insertion of the lead wire 121 into the inner wall through opening R1 and the outer wall through opening R2, thereby improving assembly efficiency. For example, the lead wire 121 can be inserted into the inner wall through opening R1 and the outer wall through opening R2 in sequence.

[0119] Optionally, the width of the through opening R1 in the inner wall is d1, the width of the through opening R2 in the outer wall is d2, and the diameter of the lead wire 121 is d. Then d < d1 < 1.5 * d, d < d2 < 1.5 * d; where d1 and d2 can be equal or unequal.

[0120] It is understandable that, for the entire inner wall through opening R1, if the width of the inner wall through opening R1 remains constant, then the width of the inner wall through opening R1 is the width at any position of the inner wall through opening R1. If the width of the inner wall through opening R1 changes, then the width of the inner wall through opening R1 can be understood as the minimum width of the inner wall through opening R1. Similarly, the same applies to the outer wall through opening R2, which will not be elaborated here.

[0121] Optionally, in Figure 7 In the example, the inner wall through opening R1 penetrates the top edge of the groove 2110 to form an inner wall through opening R11, so that the inner wall through opening R11 is connected to the insertion port of the groove 2110 through the inner wall through opening R11. The outer wall through opening R2 penetrates the top edge of the groove 2110 to form an outer wall through opening R21, so that the outer wall through opening R21 is connected to the insertion port of the groove 2110 through the outer wall through opening R21. At this time, the lead wire 121 can pass from the top of the groove 2110 downward through the inner wall through opening R11, the outer wall through opening R21 and the insertion port of the groove 2110 to cooperate with the inner wall through opening R1 and the outer wall through opening R2, so as to realize the through-line of the lead wire 121. The width of the inner wall through-hole R11 is greater than the width of the inner wall through-hole R1, and / or the width of the outer wall through-hole R21 is greater than the width of the outer wall through-hole R2, so that the inner wall through-hole R11 and / or the outer wall through-hole R21 can play a certain guiding role.

[0122] Of course, this application is not limited to this; for example, the inner wall through opening R1 and the outer wall through opening R2 may not both penetrate the top edge of the groove 2110. In this case, the lead wire 121 can be sequentially passed through the inner wall through opening R1 and the outer wall through opening R2 along the radial direction of the stator coil 12 from the radial inside of the inner wall through opening R1.

[0123] Optionally, during the assembly of the motor device 100, the lead wire 121 is passed through the inner wall through-opening R1 and the outer wall through-opening R2 of the corresponding groove 2110, such that the lead wire 121 extends out of the inner wall through-opening R1 and the outer wall through-opening R2 (e.g., Figure 10As shown), auxiliary tooling, such as a cutting tooling, can drive the cutting element 101 and the electrical connector 22 (e.g., insert 221) to move toward the groove 2110. The cutting element 101 corresponds to the outer surface of the outer wall 2110b of the groove, and the electrical connector 22 corresponds to the groove 2110. Thus, during the process of installing the electrical connector 22 into the groove 2110, the cutting element 101 cuts off the part of the lead wire 121 that extends out of the groove 2110 through the outer wall through-opening R2, so that the end of the lead wire 121 is basically flush with the outer surface of the outer wall 2110b of the groove, so as to avoid the lead wire 121 from being exposed and to ensure electrical safety.

[0124] Furthermore, in Figures 8-10 In the example, the outer surface of the terminal bracket 21 has an auxiliary support platform 2111C, which protrudes from the outer surface of the terminal bracket 21. The auxiliary support platform 2111C supports the portion of the lead wire 121 that extends out of the groove 2110 through the outer wall through-opening R2, so as to ensure that the lead wire 121 does not bend when the cutting piece 101 cuts off the portion of the lead wire 121 extending out of the groove 2110, facilitating a smooth one-time cut. When the cutting piece 101 switches the corresponding portion of the lead wire 121, it also switches the auxiliary support platform 2111C, ensuring that the terminal bracket 21 has a smooth outer surface. If other components (such as the protective bracket 23 described later) are subsequently installed on the groove 2110, it can effectively shield the outer wall through-opening R2, improving electrical safety.

[0125] It is understandable that the multiple leads 121 corresponding to the multiple grooves 2110 can be cut at once. At this time, there can be one or more auxiliary support platforms 2111C. If there is one auxiliary support platform 2111C, it can extend into a long strip along the arrangement direction of the multiple grooves 2110. If there are multiple auxiliary support platforms 2111C, they are spaced apart, and each auxiliary support platform 2111C can correspond to one groove 2110. Alternatively, the multiple leads 121 corresponding to the multiple grooves 2110 can also be cut in a certain order. At this time, there are multiple auxiliary support platforms 2111C, and each auxiliary support platform 2111C can correspond to one groove 2110.

[0126] Optionally, in Figure 10 In the example, the upper surface of the auxiliary support platform 2111C can be flush with the bottom wall of the outer wall through opening R2. Of course, the upper surface of the auxiliary support platform 2111C can also be slightly offset vertically from the bottom wall of the outer wall through opening R2.

[0127] In some embodiments, such as Figure 9 and Figure 10As shown, a support post 2111B is provided in the groove 2110 to support the lead wire 121 inserted into the groove 2110. This helps to ensure the shape stability of the part of the lead wire 121 inserted into the groove 2110 and avoids the lead wire 121 from being easily damaged by large deformation of the part of the lead wire 121 inserted into the groove 2110.

[0128] Optionally, in Figure 9 and Figure 10 In the example, the upper end face of the support column 2111B can be flush with the bottom wall of the inner wall through opening R1 and the bottom wall of the outer wall through opening R2, so that the upper end face of the support column 2111B is at the same height as the bottom wall of the inner wall through opening R1 and the bottom wall of the outer wall through opening R2. When the lead wire 121 passes through the inner wall through opening R1 and the outer wall through opening R2 and is supported on the support column 2111B, it is easy to ensure that the bottom wall of the inner wall through opening R1, the bottom wall of the outer wall through opening R2 and the support column 2111B simultaneously and effectively support the lead wire 121. This makes the part of the lead wire 121 inserted into the groove 2110 extend in a basically straight line, which helps to avoid the lead wire 121 bending during subsequent assembly and affecting the assembly efficiency.

[0129] Of course, the upper end face of the support column 2111B is not limited to this; for example, the upper end face of the support column 2111B can also be higher or lower than the bottom wall of the inner wall through opening R1 and the bottom wall of the outer wall through opening R2.

[0130] Optionally, in Figure 5 and Figure 10 In the example, the outer peripheral wall of the support column 2111B can be spaced apart from the peripheral wall of the groove 2110 so that the support column 2111B can provide enough space for the electrical connector 22 to be inserted, so as to ensure that the electrical connector 22 is inserted reliably.

[0131] In some embodiments of the present invention, such as Figure 9 and Figure 10 As shown, the insert 221 is completely housed in the groove 2110. The insert 221 is contained within the accommodating space defined by the wall of the groove 2110, so as to avoid the insert 221 being exposed and easily causing a short circuit. At the same time, it is easy to ensure that the insert 221 will not affect the assembly of the side bracket body 2111 and other components.

[0132] In some embodiments of the present invention, such as Figure 9 and Figure 10As shown, the distance L3 between the insert 221 and the insertion port of the groove 2110 satisfies the relationship 0.2mm≤L3≤0.5mm. For example, the distance between the insert 221 and the insertion port of the groove 2110 can be 0.2mm, 0.3mm, 0.42mm, or 0.5mm, etc., so as to ensure that the insert 221 is effectively inserted into the groove 2110.

[0133] In some embodiments of the present invention, such as Figure 8 and Figure 12 As shown, the wiring assembly 2 also includes a protective bracket 23, which is mounted on the wiring bracket 21. The protective bracket 23 covers the insertion port of the outer wall through opening R2 and the groove 2110 respectively. The electrical connector 22 is located inside the wiring bracket 21 and the protective bracket 23 to achieve insulation protection for the electrical connector 22 and to avoid exposure of the electrical connector 22. The terminal lead-out connection end 220 extends out of the protective bracket 23 to facilitate electrical connection between the terminal lead-out connection end 220 and other components of the compressor.

[0134] For example, in Figure 2 and Figure 12 In the example, the protective bracket 23 has a first shielding portion and a second shielding portion. The first shielding portion covers the outside of the through opening R2 on the outer wall, and the second shielding portion covers the top of the groove 2110. Figure 1 and Figure 3 In the example, the through opening R1 in the inner wall can be radially opposite to a part of the stator coil 12, so the stator coil 12 can provide a certain shielding effect on the through opening R1 in the inner wall.

[0135] Optionally, the protection bracket 23 and the wiring bracket 21 are snap-fitted together to improve the ease of assembly and disassembly of the protection bracket 23 and the wiring bracket 21. Figure 2 , Figure 3 and Figure 6 In the example, the wiring bracket 21 has at least one buckle at each of its two circumferential ends, and the buckle engages with the corresponding slot on the protective bracket 23.

[0136] In some embodiments, such as Figure 3 and Figure 12As shown, the electrical connector 22 also includes a transfer connector 222. There can be multiple transfer connectors 222. The transfer connectors 222 are disposed in the protective bracket 23 to facilitate the insulation protection of the transfer connectors 222. One end of the transfer connector 222 is inserted into the insert 221 in the groove 2110, and the above-mentioned end of the transfer connector 222 is electrically connected to the insert 221. The other end of the transfer connector 222 is connected to the terminal lead-out connection end 220. The insert 221 is electrically connected to the lead wire 121 in the corresponding groove 2110. Thus, the electrical connection between the lead wire 121 in the groove 2110 and the corresponding terminal lead-out connection end 220 is realized through the insert 221 and the transfer connector 222.

[0137] Optionally, in Figure 3 and Figure 12 In the example, the protective bracket 23 is located on the upper side of the wiring bracket 21. The side bracket body 2111 has multiple grooves 2110, and a partition boss 2111A is provided between adjacent grooves 2110. The protective bracket 23 forms a partition groove 23c, which is located between two adjacent intermediate connectors 222. The protective bracket 23 cooperates with the wiring bracket 21 so that the partition boss 2111A is inserted into the corresponding partition groove 23c, so as to effectively separate adjacent inserts 221 and adjacent intermediate connectors 222, so as to avoid short circuits caused by the protective bracket 23 during the assembly of the wiring bracket 21.

[0138] Optionally, in Figure 3 and Figure 12 In the example, the protective bracket 23 includes a first bracket 231 and a second bracket 232. The first bracket 231 is connected to the side of the second bracket 232 facing away from the wiring bracket 21 and is fastened to the second bracket 232. The first bracket 231 and the second bracket 232 together define an installation space for installing the transfer connector 222. The installation space has a first opening 23a and a second opening 23b. A portion of the transfer connector 222 is disposed in the installation space, and another portion of the transfer connector 222 extends out of the first opening 23a and extends toward the groove 2110 to contact the insert 221. The terminal lead-out connection end 220 extends into the installation space through the second opening 23b to be fixedly connected to the transfer connector 222.

[0139] Optionally, in Figure 3 and Figure 12In the example, a notch is formed on the edge of the second opening 23b, through which the lead wire 121 can pass. The terminal lead-out connection end 220 has a certain degree of flexibility, and the notch can limit the terminal lead-out connection end 220, allowing it to bend at a certain angle and extend into the second opening 23b. This facilitates the insertion of the terminal lead-out connection end 220, reduces the stress on the electrical connector 22, and ensures a reliable connection between the terminal lead-out connection end 220 and the electrical connector 22. The notch can be circular, allowing the terminal lead-out connection end 220 to fit into the circular notch through its opening. The opening of the circular notch is smaller than its diameter to prevent the terminal lead-out connection end 220 from easily detaching from the circular notch.

[0140] Furthermore, in Figure 3 In the example, the installation space is provided with a partition protrusion 232a to divide the installation space into multiple subspaces. Each subspace is provided with a corresponding intermediate connector 222 to ensure effective isolation of electrical connections between adjacent subspaces. The partition protrusion 232a may be formed on the first bracket 231 and / or the second bracket 232.

[0141] Optionally, in Figure 3 In the example, the second bracket 232 has multiple separating protrusions 232a on the side facing the first bracket 231, and the first bracket 231 also has multiple separating protrusions 232a on the side facing the second bracket 232. The multiple separating protrusions 232a of the first bracket 231 and the multiple separating protrusions 232a of the second bracket 232 are staggered, so that the separating protrusions 232a of the second bracket 232 can be inserted between adjacent two separating protrusions 232a of the first bracket 231, and the separating protrusions 232a of the first bracket 231 can be inserted between adjacent two separating protrusions 232a of the second bracket 232. This ensures the assemblability of the first bracket 231 and the second bracket 232 while maintaining electrical isolation of the wiring bracket 21, facilitating the assembly and disassembly of the first bracket 231 and the second bracket 232. The first bracket 231 and the second bracket 232 are snap-fit ​​connected.

[0142] Optionally, in Figure 3 and Figure 6 In the example, the terminal bracket 21 is a one-piece molded part, and at least part of the terminal bracket 21 is a hollow structure to ensure the structural strength and stability of the terminal bracket 21; the terminal bracket 21 is an insulating part, such as a plastic part.

[0143] For example, such as Figures 1-3As shown, the motor assembly 100 includes a motor 1 and a wiring assembly 2. The motor 1 includes a stator core 11 and a stator coil 12. The stator coil 12 is formed into a ring structure and is located at the axial end of the stator core 11. The wiring assembly 2 includes a wiring bracket 21 and an electrical connector 22. A part of the wiring bracket 21 is disposed on the outer peripheral surface of the stator coil 12, and another part is disposed between the stator coil 12 and the stator core 11. The electrical connector 22 is disposed on the wiring bracket 21 and is electrically connected to the lead wire 12 of the stator coil 12 to realize the electrical connection between the lead wire 121 of the stator coil 12 and the terminal lead-out connection end 220.

[0144] The wiring bracket 21 is bundled and fixed to the stator coil 12, and the wiring bracket 21 includes a side bracket 211, which is fixed to the outer peripheral surface of the stator coil 12. The side bracket 211 includes a side bracket body 2111 and a side bracket arm 2112. A plurality of grooves 2110 are formed on the side bracket body 2111. There are two side bracket arms 2112, which are respectively located at both ends of the side bracket body 2111. Each side bracket arm 2112 extends along the circumference of the stator coil 12, and at least one binding limiting tooth 2112a is provided on the outer surface of each side bracket arm 2112.

[0145] The terminal bracket 21 also includes an insertion bracket 212, which is disposed between the stator wire plate 12 and the stator core 11. The insertion bracket 212 includes an insertion bracket body 2121 and an insertion bracket connecting portion 2122. The insertion bracket body 2121 extends radially along the stator core 11 in a long strip shape, and the insertion bracket body 2121 is arranged opposite to one of the plurality of stator teeth 111 along the axial direction of the stator coil 12, so that on the cross-section of the stator coil 12, the insertion bracket body 2121... The orthographic projection of 121 does not exceed the outer contour of the orthographic projection of one of the stator teeth 111; the insertion bracket connecting part 2122 is connected to the lower end of the insertion bracket body 2121 and the side bracket body 2111. In the circumferential direction of the stator coil 12, the width of the insertion bracket connecting part 2122 is greater than the width of the insertion bracket body 2121, so that the insertion bracket connecting part 2122 can correspond to at least one of the stator teeth 111 and the stator slots 112 on both sides of the stator tooth 111 in the circumferential direction.

[0146] It is understandable that when the terminal bracket 21 is bundled with the stator coil 12, it can be fixed by simply bundling the side bracket arm 2112 with the stator coil 12, which simplifies the assembly process of the terminal bracket 21 and the stator coil 12.

[0147] The wiring assembly 2 also includes a protective bracket 23, which is fastened to the upper side of the side bracket body 2111 and covers the insertion ports of multiple grooves 2110. The protective bracket 23 also covers the through openings R2 on the outer walls of multiple grooves 2110, thereby covering the lead wires 121 in the grooves 2110.

[0148] The electrical connector 22 includes multiple inserts 221 and multiple intermediate connectors 222. Each insert 221 is inserted into a corresponding groove 2110, and each insert 221 is electrically connected to one intermediate connector 222. Each intermediate connector 222 is electrically connected to a terminal lead-out connection end 220. The multiple intermediate connectors 222 are mounted on the protective bracket 23, so that when the protective bracket 23 is fastened to the side bracket body 2111, the intermediate connectors 222 and their corresponding inserts 221 can be electrically connected.
