[0002] The motor stator is a crucial component of motors such as generators and starters. In motors, the arrangement of the stator winding leads is a critical factor affecting assembly efficiency, electrical performance stability, and safety. Currently, traditional motor stator lead wire arrangements suffer from the following technical defects:

[0003] The existing solution mainly consists of copper busbars, three-phase pins, and a copper busbar support. The copper busbars include U-phase, V-phase, and W-phase copper busbars, as well as a three-phase busbar. The copper busbars and three-phase pins are formed using copper plate stamping. The three-phase copper busbars and busbars are arranged horizontally in three layers through bending and staggering. The copper busbars and three-phase pins are connected by welding. The copper busbar support is made of plastic injection molding. To ensure the positional accuracy of the three pins, the support is formed through two injection molding processes. To ensure the installation strength of the busbar, the bottom of the support uses a snap-fit ​​anti-rotation design and connects to the motor stator frame. The copper busbar leads are connected to the windings via resistance clamp spot welding. This solution has low material utilization, complex structure, and high cost.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0030] Example

[0031] This embodiment provides a motor stator wire management device, such as... Figures 1-4As shown, the stator cable management device for this motor includes a cable management frame 3, a cable tube 2, a three-phase pin protective sleeve 1, and three-phase pin terminals 4. The structural design and connection relationship of each component are as follows:

[0032] Combination Figure 1 and Figure 2 As shown, the cable management frame 3 has an overall ring-shaped structure, which fits the outer periphery of the motor stator. Its core function is to support the cable management and positioning components. The cable management frame 3 has multiple through-hole cable slots 8, the width of which is larger than the diameter of the winding enameled wire, to ensure that the enameled wire can pass through smoothly.

[0033] Furthermore, in combination Figure 1 and Figure 2 As shown, the top of the cable management rack 3 is provided with three positioning connection buckles 5. The positioning connection buckles 5 are semi-circular sleeve structures. The two ends of the positioning connection buckles 5 and the outer convex sidewall are integrally formed with positioning guide strips, which are used to achieve precise positioning connection with the cable outlet tube 2.

[0034] Combination Figure 1 and Figure 2 As shown, the top of the cable management frame 3 is also equipped with an L-shaped wire clamp 6. The horizontal section of the wire clamp 6 faces downwards towards the winding enameled wire, used to clamp the winding enameled wire passing through the wire outlet groove 8 and prevent the enameled wire from becoming tangled. Combined with... Figure 4 As shown, the outer wall of the wire clamp 6 is also connected to the cable management frame 3 by a reinforcing rib 601. The reinforcing rib 601 is triangular in shape to improve the structural strength of the wire clamp 6 and prevent deformation under long-term stress.

[0035] Combination Figure 2 As shown, stator positioning buckles 7 are evenly distributed along the circumference at the bottom of the cable management frame 3. The stator positioning buckles 7 have barbs (inverted triangle type) on their inner side, which can engage with the positioning groove on the motor stator housing to achieve quick fixation of the cable management frame 3 to the stator.

[0036] In this embodiment, combined with Figure 1 and Figure 3 As shown, the cable outlet 2 has a cylindrical structure, open at the bottom and closed at the top. A cylindrical buckle 12, adapted to the positioning connection buckle 5 of the cable management frame 3, is provided on the inner wall of the lower end. The cylindrical buckle 12 is also a semi-circular sleeve structure, with a positioning guide groove on its inner wall adapted to the positioning guide strip. When the cable outlet 2 is assembled with the cable management frame 3, the positioning guide strip is embedded in the positioning guide groove to achieve circumferential positioning. Simultaneously, the positioning connection buckle 5 and the cylindrical buckle 12 are interconnected. In this embodiment, three cable outlet 2s are installed for connecting the three-phase pin terminals 4.

[0037] The lower end of the three-phase pin terminal 4 is a welding part that is welded to the enameled wire of the stator winding, and the upper end is a plug-in part for connecting to the external circuit. The three three-phase pin terminals 4 correspond to the U-phase copper busbar terminal 9, V-phase copper busbar terminal 10, and W-phase copper busbar terminal 11 of the flat wire copper busbar, respectively, and form a complete electrical circuit after connection.

[0038] The three-phase pin protection sleeve 1 is cylindrical in shape. Its inner wall is interference-fitted with the insertion part of the three-phase pin terminal 4. It is sleeved on the outside of the three-phase pin terminal 4 and interference-fitted with the outgoing tube 2. It is used to isolate external dust and oil, and at the same time plays an insulating and protective role to prevent short circuits between different phase terminals.

[0039] Working principle

[0040] The motor stator cable management device in this embodiment achieves the functions of cable management and electrical connection in the following way:

[0041] This utility model's motor stator wire management device features a low-cost solution that eliminates the need for integrated injection molding. The three-phase pin terminals 4 are formed using a stamping process, while the wire management frame 3, the three-phase pin protective sleeve 1, and the winding wire exit cylinder 2 are all injection molded. In practical application: the wire management frame 3 is used to manage the winding wire exits; the winding wire exit cylinder 2 is used to position the winding wires; the U-phase copper busbar terminals 9, V-phase copper busbar terminals 10, and W-phase copper busbar terminals 11 are respectively connected to the winding wire exits using resistance clamps for spot welding; finally, the three-phase pin protective sleeve 1 is placed on top.

[0042] The cable management frame 3 uses multiple wire clamps 6 to prevent the winding wires from scattering. The connection between the cable management frame 3 and the winding wire tube 2 is fixed with a buckle, which not only ensures the accuracy of the wire position but also facilitates installation. The three-phase pin protective sleeve 1 and the wire tube 2 are interference fit to ensure the accuracy of the three-phase pin terminal 4 wire position.

[0043] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model.
