[0043] See also Figure 1-Figure 17 The present invention discloses a wiring board, which is applied to a motor and is used to connect a coil and a power input terminal, comprising: an insulating body 10 arranged in a ring shape and a plurality of conductors 20 arranged on the insulating body 10, wherein the plurality of conductors 20 are arranged at intervals around the insulating body 10, and at least one plug hole 12 is opened around each of the conductors 20, at least part of the plug holes 12 are used for electrically connecting the conductor 20 with the coil, and part of the plug holes 12 can also be used for electrically connecting the conductor 20 with the power input terminal.

The advantages of the spirally wound arrangement are: not only the layout is beautiful and short circuits between different conductors 20 are effectively prevented, but also it is convenient to automatically assemble the conductors 20 on the insulating body 10 or to facilitate the in-mold molding of the conductors 20 on the insulating body 10.
[0045] See also Figure 2 , Figure 6 , Fig.11 and Fig.14 , a plurality of the conductors 20 are arranged at intervals in the radial direction of the insulating body 10. In some embodiments, hollow grooves 13 penetrating the upper and lower surfaces of the insulating body 10 are arranged between the conductors 20 arranged at intervals. The hollow grooves 13 can be used to quickly dissipate the heat generated when a large current passes through the conductor when the motor is working.
[0046] See also Figure 3 and Figure 4 The insulating body 10 is provided with a cutting groove 14 penetrating the upper and lower surfaces of the insulating body 10 at at least part of the ends of the conductor 20. The cutting groove 14 is used to cut the entire conductor 20 into a plurality of conductors 20 and arrange them at intervals when the entire continuously extending conductor 20 is wound around the insulating body 10 in a spiral shape, so as to achieve connection of the plurality of conductors 20 to different coils or power input terminals.
[0047] In the present invention, the welding method between the coil and the conductor 20 and the welding method between the power input terminal and the conductor 20 adopts at least one of laser welding, ultrasonic welding, non-contact induction welding, resistance welding or tin furnace immersion soldering. Through welding, the conductor 20 and the coil or the power input terminal can be firmly connected, preventing the motor from being disconnected or connected in a high current power-on process, thereby preventing the motor from being unstable.
[0048] See also Figure 1 , Figure 5 , Figure 8 , Fig.10 , Fig.13 and Fig.17 The outer circumference or inner circumference of the insulating body 10 is provided with a positioning structure 15, and the positioning structure 15 is a convex part or a concave part used to match the internal structure of the motor.
[0049] See also Fig.17The insulating body 10 is formed by splicing a plurality of insulating blocks, and each of the spliced blocks is provided with at least one conductor 20.

[0050] See also Figure 1-Figure 9 , a surface of the insulating body 10 is provided with mounting grooves 11 corresponding to the plurality of conductors 20, and the plurality of conductors 20 are mounted in the mounting grooves 11. The mounting grooves 11 can be arranged in communication with each other, so as to facilitate the installation of the entire conductor 20 and then cut into a plurality of conductors 20 by the cutting grooves 14; the mounting grooves 11 can also be arranged at intervals, and at least one conductor 20 is mounted in each mounting groove 11.
[0051] See also Figure 1-Figure 8 The wiring board also includes a plurality of lead terminals 30.

[0052] Please continue reading Figure 1-Figure 8 The bottom wall of the lead terminal groove 16 is provided with an expansion space 17 connected to the insertion hole 12 for facilitating the assembly of the lead terminal 30 into the insertion hole 12. The expansion space 17 enables the lead terminal 30 to be installed from the side of the insertion hole 12 and snapped into the insertion hole 12, which can effectively avoid the lead terminal 30 being inconvenient to insert into the insertion hole 12 due to the narrow space, thereby greatly improving the assembly efficiency.
[0053] Furthermore, the expansion space 17 located on the outer circumferential surface of the insulating body 10 is arranged through the outer circumferential surface; the expansion space 17 located on the inner circumferential surface of the insulating body 10 is arranged through the inner circumferential surface, and the expansion space 17 located on the outer circumferential surface and the inner circumferential surface of the insulating body 10 can be horizontally installed and snapped into the jack 12 through the opened opening, which further facilitates the assembly of the lead terminal 30.

In this embodiment, the clamping structure 40 is a metal part, and the clamping structure 40 can not only clamp the conductor 20 to fix the conductor 20 in the clamping groove 421, but also realize electrical conduction between the lead terminal 30 and the conductor 20. In other embodiments, the clamping structure 40 can also be a plastic part, so as to realize clamping the conductor 20, which is not particularly limited here.
[0057] Furthermore, a clamping protrusion 43 is provided on at least one side wall of the clamping portion 42 , and the conductor 20 is fixed in the clamping groove 421 through the clamping protrusion 43 .
