In addition, for convenience of description, the following portions of the present application are directly described by taking the circular ring-shaped motor stator 100 having twenty-four leads 11 as an example, and will not be described in detail below.
In some embodiments of the present invention, the wire groove 21 has a power receiving groove 22 therein, at least two wires 11 are stacked in the power receiving groove 22 substantially along a groove depth direction of the power receiving groove 22, and the first conductive member 30 includes a power receiving portion and a cutting portion, the cutting portion is located at an end of the power receiving portion close to the power receiving groove 22, the cutting portion is used for cutting an insulating skin of the wire 11, and the power receiving portion is used for electrically connecting with a conductive wire of the wire 11.
For example, as shown in fig. 7 and 8, the power receiving slot 22 has a lead slot 221 and a conductive piece slot 222, the lead slot 221 penetrates the power receiving slot 22 along the middle of the power receiving slot 22, the two leads 11 are respectively bent along the lead slot 21 and then fit into the lead slot 221 of the power receiving slot 22, and a diameter a of the lead slot 221 and a diameter b of the lead 11 can satisfy: b is less than or equal to a < 2b, so that the two leads 11 can be stacked in the connecting slot 22 along the slot depth direction of the connecting slot 22, the first conductive member 30 can be fitted in the conductive member notch 222, in this example, the lead notch 221 is located at the middle position of the conductive member notch 222 and penetrates through the conductive member notch 222, in other examples, the conductive member notch 222 can also be located at one side of the lead notch 221 and also penetrates through the conductive member notch 222, and the method is not limited herein. The purpose of the lead notch 221 penetrating through the conductive piece notch 222 is that after the lead 11 can be stacked in the lead notch 221 along the groove depth direction, in the process that the first conductive piece 30 is inserted into the conductive piece notch 222 along the groove depth direction, the cutting part can better cut off the insulation skin of the lead 11, so that the part of the conductive wire of the lead 11 is exposed, and thus, as the first conductive piece 30 continues to extend along the conductive piece notch 222, the power connection part of the first conductive piece 30 can be contacted with the conductive wire, and the power connection part has the conductive capability, so that the conductive wires of the two lead 11 with the insulation skin cut off can be electrically connected. Therefore, when wiring, the insulation skin does not need to be cut off, the lead wires 11 do not need to be welded through tin soldering, or the lead wires 11 are wound mutually in other modes, the operation is simple, and when the insulation skin is dismounted according to requirements, the first conductive parts 30 can be directly dismounted, the damage to the lead wires 11 is small, and the lead wires can be used after being reassembled.
In some examples, a positioning structure, such as a snap structure or a spring structure, may be further disposed between the first conductive member 30 and the power connection slot 22, so that the first conductive member 30 and the power connection slot 22 are relatively stable after being engaged and are not easy to fall off.
In some examples, the first conductive member 30 has a conductive groove and a cut portion at a notch of the conductive groove, the cut portion being located within the conductive groove. Referring to the structure of the first conductive member 30 in fig. 9 and 10, the conductive member has two support plates 31 and a connecting plate 32 between the two support plates 31, the contact groove 22 penetrates through the two support plates 31 and the connecting plate 32, the first conductive member 30 may be completely made of a metal material, and in fig. 10, a notch of the conductive groove has a corner, and the corner may directly cut off an insulating coating of the lead 11 when the first conductive member 30 is inserted into the lead 11, or may be made more sharp, so as to better cut off the insulating coating of the lead 11. The corner can thus be configured as a cutting section directly, but of course, the cutting of the insulation sheath can also be realized in a manner of adding a cutting knife, without limitation.
Further, in the power receiving slot 22 and the lead notch 221 of the present application, the extending direction of the notch of the power receiving slot 22 and the extending direction of the lead notch 221 are perpendicular to each other, so that the common clamping of the power receiving slot 22 and the lead notch 221 to the lead 11 can be preferably realized. In addition, it is understood that the included angle between the extending direction of the notch of the power receiving slot 22 and the extending direction of the lead notch 221 may be an acute angle, which is not limited herein as long as the common clamping of the lead 11 by the power receiving slot 22 and the lead notch 221 can be realized.
Optionally, the groove width of the conductive groove is smaller than or equal to the diameter of the conductive wire, so that the insulating sheath of the lead 11 can be cut through the notch of the conductive groove, and the groove width of the conductive groove is smaller than or equal to the diameter of the conductive wire, so that the conductive wire can be reliably clamped, virtual connection of a circuit is prevented, and potential safety hazards are brought to operation of the motor.
In some embodiments of the present invention, a plurality of wire receiving slots 22 are spaced apart along the outer periphery of the insulated wire holder 20, the wire receiving slot 21 is located on the side of the insulated wire holder 20 facing away from the end of the lead 11, the insulated wire holder 20 further has a plurality of lead 11 holes allowing the lead 11 to pass through, the plurality of lead 11 holes correspond to the plurality of leads 11 one-to-one, and the lead 11 holes of at least two electrically connected leads 11 are located in the wire receiving slot 21.

In one example, twelve power receiving slots 22 of the insulated wire holder 20 are sequentially a first power receiving slot 22 to a twelfth power receiving slot 22 along a counterclockwise direction, wherein a distance between the first power receiving slot 22 and the second power receiving slot 22 is L, a distance between the second power receiving slot 22 and the third power receiving slot 22 is m, a distance between the third power receiving slot 22, the fourth power receiving slot 22, the fifth power receiving slot 22, the sixth power receiving slot 22 and the seventh power receiving slot 22 is n, a distance between the eighth power receiving slot 22, the ninth power receiving slot 22 and the tenth power receiving slot 22 is O, a distance between the tenth power receiving slot 22, the eleventh power receiving slot 22 and the twelfth power receiving slot 22 is P, a distance between the twelfth power receiving slot 22 and the first power receiving slot 22 is Q, and the above distances satisfy: o < L < m < n, p < Q.
