Embodiment 1
[0112] A bus bar, including: a skeleton 1, a plurality of bus bars 2 and a plurality of terminals 3, such as Figure 20 shown.
[0113] Specifically, the skeleton 1 is an insulating part.
[0114] Each bus bar 2 includes a main body portion 21 and a plurality of connection portions 22, such as Figure 1 to Figure 9 as well as Figure 13 with Figure 14 shown. Wherein, the main body part 21 is embedded in the framework 1 (such as Figure 19 with Figure 20 shown), and extend along the circumferential direction of the skeleton 1, such as figure 1 , figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 13 with Figure 14 As shown; a plurality of connecting parts 22 are connected with the main body part 21 and protrude outward from the skeleton 1, such as Figure 20 As shown, it is used to connect the terminal 41 of the winding of the stator 42 of the motor.
[0115] A plurality of terminals 3 are connected to a plurality of bus bars 2, such as Figur...
Embodiment 2
[0133] The difference from the first embodiment is that on the basis of the first embodiment, further, the main body parts 21 of all the bus bars 2 are stacked and arranged along the axial direction of the skeleton 1 (such as Figure 16 to Figure 18 shown), and spaced apart from each other (such as Figure 21 to Figure 23 As shown), the connecting parts 22 of all bus bars 2 are distributed at intervals along the circumferential direction of the skeleton 1, and the end faces of all the connecting parts 22 away from the stator winding are kept flush in the axial direction of the skeleton 1, as Figure 18 with Figure 19 shown.
[0134] All the connecting parts 22 are distributed at intervals along the circumferential direction of the frame 1, corresponding to the terminals 41 of a plurality of windings distributed at intervals along the circumferential direction on the motor stator 42, and all the connecting parts 22 are in the axial direction of the frame 1 If kept flush, the...
Embodiment 3
[0166] The difference from Embodiment 2 is that: on the basis of Embodiment 2, further, the bus bar 2 connected to the terminal 3 is connected to the terminal 3 through the extension piece 221 of one of the connecting parts 22, as Figure 16 to Figure 18 shown.
[0167] For the bus bar 2 connected with the terminal 3, the bus bar 2 is connected to the terminal 3 through the extension piece 221 of one of the connecting parts 22, and there is no need to design other additional structures on the bus bar 2 to connect the terminal 3, thus The structure of the bus bar 2 is simplified, and the radial dimension of the bus bar will not be enlarged.
[0168] Certainly, the terminal 3 may also be formed by bending and extending the bus bar 2 directly. Alternatively, the terminal 3 may also be directly connected to the main body 21 and spaced apart from the connecting portion 22 .
[0169] Wherein, the extension piece 221 is perpendicular to the axial direction of the framework 1, such ...
