Embodiment 1
[0109] A bus bar, including: a skeleton 1, a plurality of bus bars 2 and a plurality of terminals 3, such as Figure 20 shown.
[0110] Specifically, the skeleton 1 is an insulating part.
[0111] 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 and Figure 14 shown. Wherein, the main body part 21 is embedded in the framework 1 (such as Figure 19 and 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 and 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.
[0112] A plurality of terminals 3 are connected to a plurality of bus bars 2, such as Figure 1...
Embodiment 2
[0148] The difference from Embodiment 1 is that: on the basis of Embodiment 1, 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.
[0149] 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.
[0150] 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 .
[0151] Wherein, the extension piece 221 is perpendicular to the axial direction of the framework 1, such ...
Embodiment 3
[0166] The difference from any of the above-mentioned embodiments is that: on the basis of any of the above-mentioned embodiments, further, the framework 1 includes a ring-shaped bracket 11 and a plurality of strip-shaped brackets 12 . Specifically, a plurality of strip brackets 12 are integrally connected with the ring bracket 11, such as Figure 23 shown. The main body portion 21 of all bus bars 2 is embedded in the annular bracket 11, such as Figure 21 to Figure 23 shown. A plurality of strip brackets 12 correspond to a plurality of terminals 3 one-to-one, such as Figure 20 As shown, and a part of each terminal 3 is embedded in the corresponding strip bracket 12, as Figure 23 and Figure 25 shown.
[0167]The framework 1 includes a ring-shaped support 11 and a strip-shaped support 12 . The ring bracket 11 is used to support multiple bus bars 2 and ensure mutual insulation between the multiple bus bars 2 . Multiple strip supports 12 are used to support multiple ter...
