[0045] The wiring portion 10 includes: a socket inner space 11 for plugging with the socket 100; and an inner clamping member 12, which is provided on a side wall of the wiring portion 10. After the socket 100 is inserted into the socket inner space 11, the inner clamping member 12 is engaged with the spring 101 on the socket 100.
[0046] When the socket 100 is plugged into the inner space 11 of the socket, the spring 101 moves along the inner space 11 of the socket from the inside to the outside, enters the inner clamping member 12, and is positioned in the inner clamping member 12;
[0047] Specifically, during implementation, a wiring portion 10 is provided; the wiring portion 10 includes: a socket inner space 11 and an inner clamp 12; the socket inner space 11 is used to be plugged into the socket 100; when the socket 100 is plugged into the socket inner space 11, the spring piece 101 on the socket 100 follows the socket inner space 11, from the inside to the outside, enters the inner clamp 12, and is positioned inside the inner clamp 12; because the socket 100 is plugged into the socket inner space 11 and is not exposed to the outside of the wiring portion 10, it is not easily affected by external factors, reduces external environmental erosion, slows down aging, and reduces the probability of the socket 100 loosening;
[0048] Another embodiment:
[0049] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown; when implemented, the outer shape of the connection portion 10 is a stepped structure, and the plane projection from top to bottom is a square;
[0050] The space 11 inside the socket is a square-shaped space, which is conducive to accommodating the socket 100;
[0051] Another embodiment:
[0052] like Figure 5 As shown; in implementation, the wiring portion 10 is provided with at least three guide grooves 13 for sliding contact with the socket 100 to limit the socket 100; the guide grooves 13 are spaced apart and communicate with the inner space 11 of the socket and are provided at different positions within the inner space 11 of the socket;
[0053] The first guide groove 13 is provided on an inner wall of one side of the wiring portion 10; the second guide groove 13 is provided on an inner wall of the other side of the wiring portion 10, and is provided opposite to the first guide groove 13.

[0054] The three guide grooves 13 are arranged in a triangle, and the triangular structure has relatively good stability;
[0055] The guide groove 13 is a rectangular space with a regular shape, which is easy to process and manufacture;
[0056] A guide groove 13 is provided to form a guide, which facilitates the insertion of the socket 100 into the inner space 11 of the socket. When the socket 100 is inserted, it will not shake up and down or left and right, and will not damage the pins on the coil assembly 400. The structural reliability is relatively good;
[0057] Another embodiment:
[0058] like Figure 5 As shown; when implemented, the wiring portion 10 is further provided with a missing space 14, the missing space 14 is close to the third guide groove 13 and communicates with the third guide groove 13 to form a stepped structure, and is provided between the first guide groove 13 and the second guide groove 13;
[0059] The missing space 14 is a rectangular parallelepiped space with a regular shape, which is easy to process and manufacture;
[0060] The missing space 14 and the guide groove 13 form a stepped structure, making the shape of the space 11 in the socket significantly asymmetrical, which is conducive to determining the insertion direction of the socket 100, preventing the socket 100 from being inserted backward and damaging the pins on the coil assembly 400, thereby improving assembly efficiency.
[0061] Another embodiment:
[0062] like Figure 5 As shown; in implementation, the connection portion 10 is further provided with a chamfer 15;

[0064] A chamfer 15 is provided to form a guide, which facilitates the insertion of the socket 100 into the inner space 11 of the socket, reduces the collision between the socket 100 and the wiring portion 10, and reduces the probability of collision damage;
[0065] Another embodiment:
[0066] like Figure 4 As shown; when implemented, the corner 16 between the socket space 11, the guide groove 13 and the missing space 14 is an angular corner;
[0067] An edge is provided, and the edge is an obtuse angle, an acute angle or a right angle, preferably a right angle, and no chamfered angle or rounded corner is provided, thereby improving the matching accuracy between the wiring portion 10 and the socket 100 and preventing foreign matter from entering through the matching gap and affecting the performance of the motor;
[0068] Another embodiment:

[0070] The wiring portion 10 is further provided with an inclined hook 17, which is provided on the inner wall of the square through-slot and is used for contacting and engaging with the spring piece 101;
[0071] A square through slot is provided, which is conducive to the engagement with the spring piece 101, and the operator can directly see whether the spring piece 101 is engaged with the square through slot, thereby preventing poor on-off contact of the motor due to improper installation of the socket 100;
[0072] An inclined hook 17 is provided, which is an inclined surface, which is conducive to contact and engagement with the spring piece 101, reducing the chance of loosening;
[0073] Another embodiment:
[0074] like Figure 6 As shown; when implemented, the inner clamping member 12 is a hook-shaped boss 12-1, which protrudes from the inner space 11 of the socket and is used to engage with the spring 101;
[0075] The wiring portion 10 is further provided with a through hole 18 , which passes through the wiring portion 10 , communicates with the inner space 11 of the socket, and faces the hook-shaped boss 12 - 1 ;
[0076] The hook-shaped boss 12-1 is provided to facilitate contact and engagement with the spring piece 101, thereby reducing the chance of loosening.

[0078] Another embodiment:
[0079] like Figure 1 As shown; during implementation, the wall thickness A at the location of the inner clamping member 12 on the wiring portion 10 is greater than the wall thickness at other locations on the wiring portion 10; the control of the wall thickness makes the structural strength of the inner clamping member 12 relatively high, preventing the plugging impact of the socket 100 from damaging the socket 100 and the inner clamping member 12, and the structural reliability is relatively good;
[0080] Another embodiment:
[0081] like Figure 8As shown; during implementation, the inner space 11 of the socket faces and is close to one end of the housing 200, away from the output shaft 301 on the transmission gear assembly 300; so that after the socket 100 is plugged into the inner space 11 of the socket, the socket 100 fits the housing 200, and the occupied space is relatively small, which is equivalent to reducing the space occupied by the motor, and the socket 100 will not collide with other components on the motor, and the structural reliability is good;
