[0027] An embodiment of this utility model provides a wiring structure for a motor stator, such as... Figure 1-5 As shown, it includes:

[0028] The stator body 100 has a plurality of winding portions 110 for winding enameled wire, and the winding portions 110 have terminal slots 120.

[0029] Lead-out terminal 200, the lead-out terminal 200 is fixed on the terminal slot 120;

[0030] The terminal block 300 has a plurality of terminal holes 310 that mate with the lead wire terminals 200. The terminal holes 310 are connected to the lead wire terminals 200. The terminal block 300 includes a wiring section 320 for connecting to an external power supply line. The wiring section 320 has a plurality of contacts 330 and the plurality of contacts 330 are electrically connected to the lead wire terminals 200 respectively.

[0031] The stator body 100 is typically made of laminated silicon steel sheets and is used to generate a magnetic field. The stator body 100 has several winding sections 110, which are areas for winding enameled wire. The enameled wire is an insulated conductor used to carry current in the motor. The winding sections 110 have terminal slots 120 for fixing lead-out terminals 200. The lead-out terminals 200 connect to the enameled wire and the terminal block 300. The terminal block 300 has several terminal holes 310 that mate with the lead-out terminals 200 to ensure that current can be smoothly transmitted from the enameled wire to the terminal block 300. The terminal block 300 includes a terminal section 320 for connecting to an external power supply. The terminal section 320 has multiple contacts 330, which are electrically connected to lead-out terminals 200 to transfer current from the dispersed lead-out terminals 200 to a centralized location for mounting terminal blocks or other components in the terminal section 320.

[0032] The working principle of this utility model is as follows:

[0033] The enameled wire is wound on the winding part 110 of the stator body 100 to form the winding of the motor stator. The winding is connected to the terminal block 300 through the lead wire terminal 200. When connecting the power cord, the terminal block 300 can be directly soldered to the power cord.

[0034] This invention simplifies traditional wiring steps, significantly improves wiring speed, and ensures the stability and reliability of welding. This wiring method not only improves production efficiency but also enhances the electrical connection quality of the motor, providing a solid guarantee for the long-term stable operation of the motor.

[0035] In some embodiments, the lead-out terminal 200 includes an insertion portion 210, on which a vertical conductive piece 220 connected to the terminal block 300 is provided. When the insertion portion 210 is inserted into the terminal slot 120, the vertical conductive piece 220 can extend out of the terminal slot 120 and be perpendicular to the radial direction of the stator body 100.

[0036] The lead-out terminal 200 includes an insertion portion 210 for insertion into a terminal slot 120. Vertical conductive pieces 220 are provided on the insertion portion 210; these conductive pieces are conductive components for connection to the terminal block 300. When the insertion portion 210 of the lead-out terminal 200 is inserted into the terminal slot 120, the position and design of the vertical conductive pieces 220 allow them to protrude from the terminal slot 120. The vertical conductive pieces 220 are radially perpendicular to the stator body 100; that is, after the lead-out terminal 200 is installed, the vertical conductive pieces 220 are perpendicular to the stator. At this time, the vertical conductive pieces 220 can be vertically inserted into the terminal block 300, simplifying the installation process.

[0037] Furthermore, the lead-out terminal 200 also includes a first bending portion 230 and a second bending portion 240. The first bending portion 230 is connected to the upper end of the insertion portion 210 and is perpendicular to the vertical conductive sheet 220. The second bending portion 240 is connected to the first bending portion 230 and forms a preset angle with the first bending portion 230.

[0038] A first bend 230 is provided at the upper end of the insertion portion 210 of the lead-out terminal 200, and a second bend 240 is further provided on the first bend 230. The second bend 240 is used for connection with the enameled wire. The preset included angle is determined by those skilled in the art according to the actual situation, for example, it can be 10-30°. The design of the second bend 240 can ensure that the connection between the lead-out terminal 200 and the enameled wire is both firm and reliable, while facilitating installation and maintenance. The design of the second bend 240 helps to ensure the stability of the connection between the lead-out terminal 200 and the enameled wire, reducing poor contact caused by vibration or mechanical stress.

[0039] Furthermore, the second bend 240 is provided with a groove 250 for fixing the enameled wire.

[0040] A groove 250 is provided on the second bend 240, which is specifically designed to secure the enameled wire. The shape and size of the groove 250 match the diameter of the enameled wire to ensure that the enameled wire can be securely fixed in place.

[0041] Furthermore, the insertion part 210 is provided with a protrusion 260 for engaging with the terminal slot 120.

[0042] A protrusion 260 is provided on the insertion part 210. This protrusion 260 is specifically designed to engage with the terminal slot 120. The engagement of the protrusion 260 with the terminal slot 120 provides additional stability, ensuring that the lead terminal 200 is fixed in position in the terminal slot 120, and preventing the lead terminal 200 from loosening or shifting due to vibration or mechanical stress.

[0043] Furthermore, the 260 protrusion is formed by stamping.

[0044] A protrusion 260 is designed on the insertion portion 210 of the lead terminal 200 and manufactured using a stamping process. This ensures that the protrusion 260 has a precise and consistent shape and good mechanical strength. This process allows for the rapid production of a large number of standardized protrusions 260, meeting the needs of mass production.

[0045] In some embodiments, the winding portion 110 has extension portions 130 on both sides of the stator body 100 in the radial direction, and the terminal slot 120 is disposed on the extension portion 130 near the outer side of the stator body 100.

[0046] Extensions 130 are provided on both sides of the stator body 100 in the radial direction. These extensions 130 extend out of the winding portion 110, increasing the size of the stator body 100 and providing space for the terminal slot 120.

[0047] Furthermore, the terminal block 300 is detachably connected to the extension section 130.

[0048] The detachable connection means that the connection between the terminal block 300 and the extension 130 can be easily disassembled and reinstalled via a mechanism such as clips, screws, welding, or other fasteners. This detachable connection simplifies the installation and maintenance of the terminal block 300. When the terminal block 300 needs to be replaced or repaired, workers can quickly disassemble it without requiring complex operations on the entire motor stator.

[0049] Furthermore, the extension 130 is provided with a fixing post 140, and the wiring plate 300 is provided with a fixing hole 150 that cooperates with the fixing post 140.

[0050] The extension portion 130 is provided with fixing posts 140, which are mechanical structures for connecting to the terminal block 300. The fixing posts 140 may be columnar structures, protruding from the surface of the extension portion 130 for insertion into the fixing holes 150 of the terminal block 300. The terminal block 300 is provided with fixing holes 150 that mate with the fixing posts 140. The size and shape of these holes match the fixing posts 140, ensuring that the fixing posts 140 can be inserted into and secure the terminal block 300. The precise fit between the fixing posts 140 and the fixing holes 150 ensures a strong and stable connection between the terminal block 300 and the extension portion 130, reducing loosening caused by vibration or mechanical stress.

[0051] In some embodiments, an inclined portion 160 is provided on the extension portion 130 near the outside of the stator body 100, and the inclined portion 160 is used to guide the enameled wire to connect with the lead wire terminal 200.

[0052] An inclined portion 160 is provided on the extension 130 near the outer side of the stator body 100. This inclined portion 160 is part of the extension 130 and is designed in an inclined shape to guide the enameled wire to connect with the lead-out terminal 200. The design of the inclined portion 160 helps guide the enameled wire to smoothly transition from one position to another, especially during the process of the enameled wire being led out from the winding portion 110 and connected to the lead-out terminal 200. This design can reduce the bending stress of the enameled wire and avoid damage to the enameled wire due to excessive bending. The inclined portion 160 can reduce the stress on the enameled wire during the connection process and extend the service life of the enameled wire. The design of the inclined portion 160 can also improve the appearance neatness of the motor because the routing of the enameled wire is more orderly, reducing the messy wire bundle.
