Busbar structure

Abstract

To provide a bus bar structure capable of insulating a plurality of bus bars from each other with a simple configuration.SOLUTION: A bus bar structure 10 according to an embodiment includes a bus bar holder 20 that accommodates a bus bar, a first bus bar 31a, a second bus bar 31b, and a ring-shaped insulating plate 50 that insulates the first bus bar 31a and the second bus bar 31b. A first vertical portion 33a of the first bus bar 31a and a second vertical portion 33b of the second bus bar 31b are fitted into a cutout portion 51 of the ring-shaped insulating plate 50, and the ring-shaped insulating plate 50 is inserted between a first bus bar main body portion 32a of the first bus bar 31a and a second transition portion 34b of the second bus bar 31b, thereby insulating the first bus bar 31a and the second bus bar 31b.SELECTED DRAWING: Figure 13

The insulating member (50) has a ring shape, The notch (51) of the insulating member (50) includes a radial notch (52) formed to extend along the radial direction and a circumferential notch (53) connected to the radial notch (52) and formed to extend along the circumferential direction. When the first vertical portion (33a) of the first busbar (31a) and the second vertical portion (33b) of the second busbar (31b) are inserted into the radial notch (52) of the notch (51) of the insulating member (50), the insulating member (50) rotates along the circumferential direction, causing the first vertical portion (33a) of the first busbar (31a) and the second vertical portion (33b) of the second busbar (31b) to fit into the circumferential notch (53).

2. The bus bar holder (20) is The first housing portion (24a) includes the first groove portion (24a), The second housing portion (24b) includes the second groove portion (24b), A wall portion (23a) is provided between the first groove portion (24a) and the second groove portion (24b), The busbar structure according to claim 1, wherein the wall portion (23a) is inserted between the first busbar body portion (32a) of the first busbar (31a) housed in the first groove and the second busbar body portion (32b) of the second busbar (31b) housed in the second groove.

3. The system further comprises a cover member (60) that covers the insulating member (50), The cover member (60) has a snap-fit ​​projection (61), The bus bar structure according to claim 1 or 2, wherein the bus bar holder (20) has a snap-fit ​​fitting portion (26) into which the snap-fit ​​projection (61) fits.

4. The first busbar body portion (32b) and the second busbar body portion (32e) each have a third vertical portion (35b, 35e) extending along the axial direction, The busbar structure according to claim 3, wherein the cover member (60) has a support portion (62) that insulates and supports the third vertical portions (35b, 35e) from each other.
