[0046] The embodiments of this utility model 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 this utility model, and should not be construed as limiting this utility model.

[0047] The following is for reference. Figures 1-12 A motor 1000 according to a first aspect embodiment of the present invention is described.

[0048] like Figures 1-12 As shown, the motor 1000 according to the first aspect embodiment of the present invention includes: a stator assembly 200 and a connector assembly 100.

[0049] Specifically, the connector assembly 100 has a number of mating positions, N ≥ 4, and the connector assembly 100 includes connectors, M ≤ N, the number of connectors 20 is M, and the connectors 20 have a connecting end 201 and a mating end 202. The connecting end 201 is electrically connected to the stator assembly 200 and / or electronic components, and the mating end 202 is located within the connector assembly 100 and extends to the mating position. The mating end 202 is used for electrical connection with an external interface. It is understood that the connector assembly 100 has at least four mating positions, so that the connector assembly 100 can be used to connect multiple external interfaces simultaneously. The number M of connectors 20 does not exceed the number N of mating positions, so each connector 20 can be set in a mating position, and there are situations where the mating positions are empty and spare. The connector 20 is formed with a connecting end 201 and a mating end 202. The connecting end 201 is used for electrical connection with the stator assembly 200 and / or electronic components. That is, the connecting end 201 of the connector 20 can be connected to the stator assembly 200, the connecting end 201 of the connector 20 can also be connected to electronic components, and the connecting end 201 of the connector 20 can also be connected to both the stator assembly 200 and electronic components. The mating end 202 is located inside the connector assembly 100, and one end of the mating end 202 extends to the mating position, which facilitates electrical connection with external interfaces. This allows current to be transmitted efficiently and reliably from the stator assembly 200 to the plug-in terminal 202. Both the connection terminal 201 and the plug-in terminal 202 are integrated on the connector 20, reducing the assembly steps between the plug-in terminal 202 and the connection terminal 201, and improving the connection stability and reliability between components.

[0050] In other words, in the existing technology, the stator assembly is first electrically connected to the connector, then electrically connected to the plug-in terminal via multiple insulated wires, and finally connected to the external interface. The entire process involves four independent electrical connections, which increases the number of parts used, complicates the manufacturing process, and reduces production efficiency. Multiple connections also affect the reliability of the connection, increase the possibility of failure, increase costs, and make some areas of the motor larger, which can easily cause space interference problems during installation. In this application, both the connector 201 and the plug-in terminal 202 are integrated into the connector 20, reducing the need for multiple electrical connections in the traditional design. Only the stator assembly 200 needs to be connected to the connector 20, reducing the number of connection points and achieving large integration in a small space.

[0051] Furthermore, the number M of connectors 20 does not exceed the number N of plug positions, so that each connector 20 can be set in a plug position. Moreover, there are situations where plug positions are empty and spare. The number of connectors can be flexibly configured according to actual needs. At the same time, it supports the connection of multiple components, increasing the scalability and compatibility of the connector assembly 100.

[0052] According to the embodiment of the present invention, the motor 1000 limits the number M of connectors 20 to no more than the number N of plug positions and the number of plug positions to no less than 4. In this way, each connector 20 can be set in a plug position, and there are situations where plug positions are empty and spare. The number of connectors 20 can be flexibly configured according to actual needs. At the same time, it supports the connection of multiple components, increasing the scalability and compatibility of the connector assembly 100. The connector 20 has a connection end 201 connected to the stator assembly 200 and a plug end 202 connected to the external interface, reducing the need for multiple electrical connections in traditional designs. Only the stator assembly 200 needs to be connected to the connector 20, thereby simplifying the assembly process of the motor 1000, reducing the number of connection points, reducing the risk of failure due to poor contact or looseness, making the overall size of the motor 1000 more compact, avoiding space waste caused by multiple independent components, and helping to solve the space interference problem that may occur during installation.

[0053] It should be noted that the number of plug positions N can be any integer from 4 to 10, that is, the number of plug positions can be 4, 5, 6, 7, 8, 9, or 10; the number of connectors 20 M can be any integer from 4 to 6, that is, the number of connectors 20 can be 4, 5, or 6.

[0054] When the number of connectors 20 M is 4, the connector assembly 100 has a three-phase output terminal and a ground terminal, and the number of mating positions N can be any integer from 4 to 10. Each mating position is provided with a connector 20. When the number of mating positions N is greater than the number of connectors 20 M (i.e., when the number of mating positions N is greater than 4), the mating position has a spare position.

[0055] When the number of connectors 20 M is 5, the connector assembly 100 has a three-phase output terminal and an identification resistor (the two ends of the identification resistor are respectively connected to a connector 20, that is, it has a three-phase output terminal and two resistor terminals 303), and the number of mating positions N can be any integer from 4 to 10. Each mating position is provided with a connector 20. When the number of mating positions N is greater than the number of connectors 20 M (that is, when the number of mating positions N is greater than 5), the mating position has a spare position.

[0056] When the number of connectors M is 6, the connector assembly 100 has a three-phase output terminal, a ground terminal and an identification resistor (the two ends of the identification resistor are respectively connected to a connector 20, that is, it has a three-phase output terminal and two resistor terminals 303), and the number of mating positions N can be any integer from 4 to 10. Each mating position is provided with a connector 20. When the number of mating positions N is greater than the number of connectors 20 M (that is, when the number of mating positions N is greater than 6), the mating position has a spare position.

[0057] Furthermore, it is understandable that the connector 20 is a one-piece molded design.

[0058] Reference Figure 3 As shown, the connector assembly 100 has 10 mating positions, which are arranged in two rows, with 5 mating positions in each row.

[0059] In some embodiments of this invention, the connecting end 201 is connected to the stator assembly 200 and / or electronic components by welding. Specifically, the connecting end 201 is connected to the stator assembly 200 and / or electronic components by resistance welding, soldering, or cold soldering. This achieves large-scale integration within a small space in the connector assembly 100, making the structure of the connector assembly 100 more compact and its integration higher.

[0060] In some embodiments of this utility model, such as Figure 9 As shown, the connector assembly 100 includes a connector base 10, a connector 20 which is a power connector 301, and a stator assembly 200 with a stator winding 2001. The stator winding 2001 has a connecting lead 2002, which is connected to and electrically connected to the connector terminal 201. In other words, the connector terminal 202 is connected to an external interface, and the connector terminal 202 and the connector terminal 201 are integrally formed, providing the required power input to the motor 1000. This simplifies the power connection process for the motor 1000 and improves the overall efficiency and reliability of the system.

[0061] In some embodiments of this utility model, such as Figure 9 As shown, an intermediate portion 3011 is formed between the connecting end 201 and the plug-in end 202, and a fixing groove 101 is formed in the connector base 10, with the intermediate portion 3011 disposed within the fixing groove 101. It can be understood that the connecting end 201 and the plug-in end 202 are connected via the intermediate portion 3011. The connecting end 201, the plug-in end 202, and the intermediate portion 3011 are integrally formed. The intermediate portion 3011 improves the structural strength of the integrally formed connecting end 201 and the plug-in end 202. The intermediate portion 3011 being disposed within the fixing groove 101 reduces assembly difficulty and provides stable support for the connecting end 201 and the plug-in end 202, preventing the intermediate portion 3011 from moving under vibration or other external forces, thereby avoiding movement between the connecting end 201 and the plug-in end 202.

[0062] In some embodiments of this utility model, such as Figure 7As shown, the connector base 10 has a placement portion 102, and the connecting end 201 is disposed on the placement portion 102. It can be understood that the placement portion 102 is used to support the placement of the connecting end 201. The placement portion 102 cooperates with the fixing groove 101 to fix the power connector 301 on the connector base 10, which not only facilitates assembly but also improves the assembly accuracy of the power connector 301. It also prevents displacement of the connecting end 201 and the plug end 202 during use, thereby improving the reliability and durability of the connector assembly 100.

[0063] In one specific embodiment, the placement part 102 is formed as a placement platform, and the side surface of the placement platform away from the connector base 10 is formed as a placement surface 1021. The connection end 201 is placed on the placement surface 1021. The contact area between the connection end 201 and the placement platform is large, and the connection structure is stable.

[0064] In some embodiments of this utility model, the connector base 10 has a lead wire fixing part 103, which is disposed on opposite sides of the placement part 102. It is understood that the lead wire fixing part 103 is used to fix the connecting lead 2002 of the stator winding 2001 at the lead wire inlet and lead wire outlet of the placement part 102. This facilitates positioning the relative position between the connecting lead 2002 and the connection end 201, improving assembly efficiency and accuracy, and enhancing mechanical stability and electrical connection reliability. Furthermore, by providing the placement part 102, the fixing groove 101, and the lead wire fixing part 103, the connector base 10 has a compact structure, reducing the overall size of the motor 1000 and avoiding spatial interference problems during installation.

[0065] Reference Figure 6 and Figure 7 As shown, the lead wire fixing part 103 is formed as a lead wire groove 1031. The connecting lead wire 2002 passes through and exits the lead wire groove 1031. Specifically, the connecting lead wire 2002 first passes through and exits one of the lead wire grooves 1031, and then the connecting lead wire 2002 contacts the connecting end 201. After passing through the connecting end 201, the connecting lead wire 2002 passes through and exits the other lead wire groove 1031. This facilitates the connection of the connecting lead wire 2002 to the connecting end 201, reduces the assembly difficulty, and the lead wire fixing part 103 makes the connecting lead wire 2002 arranged in an orderly manner on the connector base 10, avoiding spatial interference during installation.

[0066] In some embodiments of this utility model, the connector base 10 has a cutting and fixing portion 104, which is disposed at the free end of the connecting lead 2002. It is understood that the cutting and fixing portion 104, disposed at the end portion of the connecting lead 2002, is used to fix the connecting lead 2002 during assembly with the connecting wire. Furthermore, after the connecting end 201 and the connecting lead 2002 are assembled, it facilitates the cutting of any excess connecting lead 2002, which helps to speed up production and reduce production costs.

[0067] Reference Figure 6 and Figure 7 As shown, the cutting and fixing part 104 is formed as a wire cutting groove 1041, and the end of the connecting lead 2002 is located in the wire cutting groove 1041. The fixing method of the connecting lead 2002 and the wire cutting groove 1041 is simple, which reduces the production difficulty and facilitates the operation of production personnel.

[0068] In some embodiments of this utility model, the cutting and fixing part 104 is snapped into place with the free end of the connecting lead 2002. It is understood that this snap-fit ​​connection is simple, securely holds the free end of the connecting lead 2002, and facilitates the removal of the lead segment from the wire cutting groove 1041 after the excess connecting lead 2002 is cut, reducing the difficulty of snapping and removal, thereby improving production efficiency.

[0069] In some embodiments of this utility model, a limiting flange 2011 is formed around the periphery of the connecting end 201, and a wire groove 2012 is formed on the limiting flange 2011. It can be understood that the limiting flange 2011 is formed around the periphery of the connecting end 201 so that when the connecting end 201 is soldered to the connecting lead 2002, the surface tension of the solder is relatively large. When the solder flows to the limiting flange 2011, it cannot continue to flow due to the obstruction of the limiting flange 2011. More and more solder accumulates in the thickness direction of the connecting end 201, thereby enabling the connecting end 201 and the connecting lead 2002 to be stably connected.

[0070] In some embodiments of this utility model, the connector base 10 includes a base body 60 and a connector body 70, which are integrally formed, or the base body 60 and the connector body 70 are detachably connected. It is understood that the integral formation of the base body 60 and the connector body 70 reduces the number of parts and improves the stability and reliability of the structure; the detachable connection of the base body 60 and the connector body 70 facilitates assembly, maintenance, and replacement, making it suitable for situations requiring frequent maintenance or component replacement, and providing greater flexibility.

[0071] In some embodiments of this utility model, multiple power connectors 301 are arranged at intervals on the base 60. The fixing slots 101 and placement portions 102 are arranged one-to-one with each power connector 301. It is understood that the spaced arrangement of multiple power connectors 301 on the base 60 ensures that each power connector 301 has independent mechanical support and a path for electrical connection, improving the reliability and ease of assembly of the connector assembly 100. The one-to-one correspondence between the fixing slots 101 and placement portions 102 ensures that each power connector 301 corresponds to a fixed placement portion 102 and fixing slot 101, guaranteeing that each power connector 301 can be accurately installed in the corresponding position and electrically connected to the corresponding power connector 301. This effectively avoids electrical interference and short circuits, improving the safety of the motor 1000.

[0072] In some embodiments of this utility model, the connector 20 is a grounding connector 302. The connecting end 201 is connected to the stator core 2003 of the stator assembly 200. A reinforcing portion 3021 is formed between the connecting end 201 and the plug-in end 202. The connector base 10 has a grounding through hole 1051, and the reinforcing portion 3021 is located within the grounding through hole 1051. It can be understood that the plug-in end 202 is connected to the connecting end 201 through the reinforcing portion 3021 to enhance the mechanical structural strength of the grounding connection. The connecting end 201 and the plug-in end 202 are integrally formed, which improves the connection stability and reliability.

[0073] In summary, the shape and dimensions of the fixing groove 101 match the shape and dimensions of the intermediate portion 3011, including but not limited to this.

[0074] In some embodiments of this utility model, the connector base 10 has a first boss 105, and a grounding through hole 1051 passes through the first boss 105. (Refer to...) Figure 7 As shown, a first boss 105 is formed on the connector base 10. The first boss 105 is arranged at a distance from the fixing groove 101. The grounding through hole 1051 passes through the connector base 10 and the first boss 105. Thus, the first boss 105 enhances the structural strength and stability of the grounding through hole 1051.

[0075] In some embodiments of this utility model, the connector assembly 100 further includes: a housing 40, which covers the connector base 10. A first sealing surface 1011 is formed around the periphery of the fixing groove 101, and a second sealing surface 402 is formed on the housing 40. The first sealing surface 1011 and the second sealing surface 402 are in contact. It is understood that the first sealing surface 1011 is located around the periphery of the fixing groove 101 and is used to contact the second sealing surface 402 on the housing 40 to ensure a good sealing effect. The housing 40 covers the connector base 10, protecting the internal components from the influence of the external environment. The second sealing surface 402 on the housing 40, in contact with the first sealing surface 1011, ensures a sealing effect. The second sealing surface 402 on the housing 40, in contact with the first sealing surface 1011 on the connector base 10, forms an effective sealing structure, preventing injection molding compound, moisture, and dust from entering the connector. This improves the sealing performance of the connector assembly 100 and enhances its reliability and durability.

[0076] In some embodiments of this utility model, such as Figure 7 As shown, the connector base 10 has a second boss 106, a fixing groove 101 is formed on the second boss 106, and the side surface of the second boss 106 facing away from the connector base 10 is formed as a first sealing surface 1011. The housing 40 has a third boss 401, and the side surface of the third boss 401 facing away from the housing 40 is formed as a second sealing surface 402. The second boss 106 and the third boss 401 are arranged correspondingly. Understandably, the second boss 106 is provided on the connector base 10, the fixing groove 101 is formed on the second boss 106, and the first sealing surface 1011 is provided on the side surface of the second boss 106 away from the connector base 10, for fitting with the second sealing surface 402 on the housing 40 to ensure a good sealing effect. The housing 40 covers the connector base 10 to protect the internal components from the influence of the external environment. The housing 40 is provided with a third boss 401, and the side surface of the third boss 401 away from the housing 40 is formed as the second sealing surface 402, which fits with the first sealing surface 1011 to ensure a sealing effect. The third boss 401 is provided on the housing 40 and is arranged correspondingly to the second boss 106. The second sealing surface 402 is provided on the side surface of the third boss 401 away from the housing 40 and fits with the first sealing surface 1011 on the connector base 10 to form an effective sealing structure to prevent injection molding plastic, moisture and dust from entering the connector. This improves the sealing performance of the connector assembly 100, enhances its reliability and durability, and also prevents electrical interference between the mating ends 202.

[0077] In some embodiments of this utility model, a fixing rib 403 is formed on the third boss 401. The fixing rib 403 extends into the fixing groove 101 and abuts against the middle part 3011. It can be understood that the fixing rib 403 is provided on the third boss 401, and the fixing groove 101 is provided on the second boss 106. The fixing rib 403 extends into the fixing groove 101 and abuts against the middle part 3011, which enhances the mechanical locking effect of the middle part 3011 and prevents the middle part 3011 from loosening or shifting during use, thereby ensuring the stability of the power connector 301 and the connector 20.

[0078] In some embodiments of this utility model, the fixing groove 101 has a first guide surface 1012, which is connected to the first sealing surface 1011. The fixing rib 403 has a second guide surface 4031, and the fixing rib 403 and the fixing groove 101 are guided by the first guide surface 1012 and the second guide surface 4031. (Refer to...) Figure 7 , Figure 8 , Figure 11 and Figure 12 As shown, the first guide surface 1012 is disposed within the fixing groove 101 and connected to the first sealing surface 1011, used to guide the correct installation position of the fixing rib 403. The second guide surface 4031 is disposed on the fixing rib 403 and cooperates with the first guide surface 1012 to guide it, ensuring that the fixing rib 403 can be accurately inserted into the fixing groove 101 and abut against the middle part 3011. Thus, the fixing rib 403 and the fixing groove 101 are guided by the cooperation of the first guide surface 1012 and the second guide surface 4031, so that the fixing rib 403 can be smoothly assembled into the fixing groove 101, reducing the assembly difficulty of the fixing groove 101 and the fixing rib 403, ensuring the accuracy of assembly, and improving the assembly efficiency.

[0079] In some embodiments of this utility model, a sealing groove 404 is formed on the housing 40, and the sealing groove 404 is correspondingly arranged with the placement part 102 in the arrangement direction of the housing 40 and the connector base 10. It can be understood that the sealing groove 404 has the function of avoiding solder blocks on the connector 20. After the housing 40 is fully assembled onto the connector base 10, the sealing groove 404 is filled with plastic to seal it, ensuring the waterproof and dustproof performance of the connector assembly 100 and preventing moisture and dust from entering the interior of the connector assembly 100. In addition, the plastic filling can prevent the connector 20 from shifting, making the connection between the connecting lead 2002 and the connector 20 more stable and less prone to breakage.

[0080] Furthermore, a sealing partition 405 is provided between any two adjacent sealing grooves 404. The sealing partition 405 is used to insulate and separate two adjacent connectors 20 to ensure the electrical connection safety of the connector assembly 100.

[0081] In some embodiments of this invention, the sealing groove 404 is filled with injection molding material. It is understood that the injection molding material can fill any minute gaps in the sealing groove 404, helping to prevent moisture, dust, and other contaminants from entering the connector assembly 100, thereby improving overall reliability and durability, ensuring consistent and reliable sealing performance, and improving production efficiency and product quality. Injection molding materials typically have good weather resistance and anti-aging properties, maintaining their sealing characteristics during long-term use, extending the service life of the connector assembly 100. Furthermore, the injection molding material has a shock-absorbing effect, absorbing external impacts and vibrations, protecting critical internal components from damage.

[0082] In some embodiments of this utility model, the connector base 10 is formed as an insulating material to ensure electrical isolation and safety, and to prevent current leakage and other electrical faults.

[0083] In some embodiments of this utility model, a plurality of receiving grooves 406 are formed on the housing 40, and the plurality of receiving grooves 406 are arranged at intervals. Terminal through holes 4091 are formed at the bottom of M of the receiving grooves 406, and the plug-in end 202 extends into the terminal through holes 4091. It is understood that the receiving grooves 406 are provided on the housing 40, and the plurality of receiving grooves 406 are arranged at intervals. The terminal through holes 4091 formed at the bottom of the M receiving grooves 406 are used to accommodate the plug-in end 202. The plug-in end 202 is placed within these terminal through holes 4091, ensuring that the plug-in end 202 remains stable and reliable during use, reducing interference between the plug-in ends 202, and improving the safety of the electrical connection.

[0084] Reference Figure 10 As shown, the connector assembly 100 has 10 insertion positions, which are arranged in two rows with 5 insertion positions in each row. There are 10 receiving slots 406, each of which forms a insertion position. The bottom of six of the ten receiving slots 406 has terminal through holes 4091, and each terminal through hole 4091 accommodates a insertion terminal 202. The connector 20 can be a power connector 301, a ground connector 302, and a resistor terminal 303.

[0085] In some embodiments of this utility model, at least one of the plurality of receiving slots 406 has a foolproof part 4061 formed therein. It is understood that the foolproof part 4061, provided in at least one receiving slot 406, is used to prevent incorrect assembly, ensuring that the connector assembly 100 is correctly aligned and secured during the installation of the motor 1000 and the device. This avoids assembly problems caused by human error, helps reduce the error rate during assembly, and improves production efficiency and product quality.

[0086] Reference Figure 10 As shown, the error prevention part 4061 is formed as an error prevention groove.

[0087] In some embodiments of this utility model, a connector boss 407 is formed on the housing 40, a plurality of receiving grooves 406 are formed on the connector boss 407, and a snap-fit ​​portion 4071 is formed on the outer peripheral wall of the connector boss 407. (Refer to...) Figure 10 As shown, a connector boss 407 is formed on the housing 40, a receiving groove 406 is formed on the connector boss 407, and a terminal through hole 4091 passes through the bottom of the connector boss 407 and communicates with the receiving groove 406. Thus, the connector boss 407 enhances the structural strength and stability of the receiving groove 406 and the terminal through hole 4091, and facilitates the insertion of the motor 1000 into the device, thereby improving the insertion strength.

[0088] In some embodiments of this invention, at least a portion of the circumferential direction of the housing 40 is formed with a connector sealing surface 408. It is understood that the connector sealing surface 408 is located in the circumferential direction of the housing 40. The connector sealing surface 408 can be a continuous sealing surface or spaced sealing surfaces. After the motor 1000 is assembled with the device, the connector sealing surface 408 provides an additional sealing layer in the circumferential direction of the housing 40, preventing moisture, dust, and other contaminants from entering the connector assembly 100, thereby improving the overall sealing effect. The connector sealing surface 408 also helps simplify the assembly process. Using the connector sealing surface 408 as a reference plane ensures that the various components can be correctly aligned and fixed during assembly, avoiding unnecessary adjustments and rework.

[0089] In some embodiments of this utility model, the housing 40 forms a receiving cavity 409, the terminal through hole 4091 communicates with the receiving cavity 409, the connector 20 is a resistor terminal 303, the resistor terminal 303 passes through the receiving cavity 409 and extends into the terminal through hole 4091, and the connector assembly 100 further includes a resistor 50, the resistor 50 is located in the receiving cavity 409, and the two ends of the resistor 50 are respectively connected to the resistor terminal 303. In other words, by integrating the resistor 50 into the housing 40, the structure of the existing motor 1000 connector is simplified, the number of components and process complexity are reduced. The housing 40 has a receiving cavity 409 and a terminal through hole 4091. The receiving cavity 409 is used to place the resistor 50, and the terminal through hole 4091 is used to insert the resistor terminal 303. The resistor terminal 303 passes through the receiving cavity 409 and extends into the terminal through hole 4091, ensuring electrical connection while also playing a mechanical fixing role. The resistor 50 is located in the receiving cavity 409, and the two ends of the resistor 50 are connected to the corresponding resistor terminal 303 to realize the resistance function.

[0090] Understandably, by directly integrating the resistor 50 into the connector assembly 100, steps such as external soldering and heat shrink tubing protection are reduced, greatly simplifying the assembly process. Furthermore, the elimination of additional components such as insulated wires, heat shrink tubing, and cable ties reduces the overall production cost of the connector. The integrated design reduces the number of connection points, thereby reducing the risk of poor contact, avoiding the influence of the external environment on the resistor 50, improving the reliability of the connector, and making the overall structure more compact and space-saving.

[0091] Furthermore, such as Figure 4 As shown, the connector assembly 100 also includes a cover 4010, which cooperates with the housing 40 to define a receiving cavity 409. A clearance groove 40101 is formed on the side of the cover 4010 facing the receiving cavity 409, which is used to avoid the resistor 50. It is understood that the cover 4010 is used to close the receiving cavity 409, ensuring the safety and stability of the internal components. The clearance groove 40101, located on the side of the cover 4010 facing the receiving cavity 409, is used to accommodate the resistor 50, providing additional space and protection for the resistor 50. Furthermore, the shape and size of the clearance groove 40101 match the shape and size of the resistor 50, ensuring that the resistor 50 can be securely placed. Therefore, not only is the internal structural layout of the housing 40 optimized, but better protection and support are also provided for the resistor 50.

[0092] An electrical appliance according to a second aspect of the present invention includes a motor 1000 according to the first aspect of the present invention described above.

[0093] According to the electrical appliance of this utility model embodiment, by limiting the number M of connectors 20 to no more than the number N of plug positions and the number of plug positions to not less than 4, each connector 20 can be set in a plug position independently. Furthermore, there are situations where plug positions are empty or spare, and the number of connectors 20 can be flexibly configured according to actual needs. At the same time, it supports the connection of multiple components, increasing the scalability and compatibility of the connector assembly 100. The connector 20 has a connection end 201 connected to the stator assembly 200 and a plug end 202 connected to an external interface, reducing the need for multiple electrical connections in traditional designs. Only the stator assembly 200 needs to be connected to the connector 20, thereby simplifying the assembly process of the motor 1000, reducing the number of connection points, reducing the risk of failure due to poor contact or looseness, thereby improving the yield rate of the electrical appliance and reducing the installation space of the electrical appliance.
