[0005] Preferably, the No. 1 U-phase copper busbar, No. 2 V-phase copper busbar, and No. 3 W-phase copper busbar are bent parts formed by bending a 1mm thick copper plate, which are characterized by consisting of "U"-shaped terminals on two sides and a middle protruding end, and the angle between the middle protruding end and the "U"-shaped terminals on both sides is 45°, the long side of the "U"-shaped terminal is 3mm, the inner diameter of the semicircle is 3mm, and the width is 3mm.

[0006] Preferably, the No. 4 common terminal copper busbar is a bent part formed by bending a 1mm thick copper plate, which is characterized by being composed of three "U"-shaped terminals. The angle between the "U"-shaped terminals is 30°, the long side length of the "U"-shaped terminal is 3mm, the inner diameter of the semicircle is 3mm, and the width is 3mm.

[0007] Preferably, the No. 5 positioning foot has an upper portion that is a column with a cross-section of 2mm×5mm, and a lower portion that is a rectangular parallelepiped structure with a size of 1mm×3mm×3mm and chamfered on three sides at the end.

[0008] Preferably, the upper portion of the No. 6 support leg is a column with a cross-section of 2mm×5mm.

[0009] Beneficial effects achieved by the utility model:

[0010] According to the utility model, a stable and reliable motor wiring structure is provided for motor wiring, which can improve wiring stability and facilitate automated production line production. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The No. 1 U-phase copper bar, No. 2 V-phase copper bar, and No. 3 W-phase copper bar are arranged in sequence at intervals of 30° in the circumferential direction and 1 mm apart in the axial direction. The No. 4 common-end copper bar is flush with the No. 1 U-phase copper bar in the axial direction, and its middle "U"-shaped terminal forms an angle of 89° with the middle protruding end of the No. 1 U-phase copper bar. Another No. 4 common-end copper bar forms an angle of 90° with the above-mentioned No. 4 common-end copper bar.

[0018] The No. 5 positioning foot and No. 6 supporting foot are formed together with the No. 1 U-phase copper bar, No. 2 V-phase copper bar, No. 3 W-phase copper bar and No. 4 common end copper bar through injection molding as injection molding features. The thickness of the injection molding layer on the outer side of the copper bar is 1 mm. The angle between the two No. 5 positioning feet is 120°. The two supporting feet are respectively located directly below the middle protruding end of the No. 1 U-phase copper bar and the middle protruding end of the No. 3 W-phase copper bar.
