发明名称 Electricity collection and distribution ring and electric motor
摘要 An electricity collection and distribution ring 90 includes a plurality of bus rings 1-3 that include a plurality of annular conductive bodies 10, 20, 30 and a plurality of connecting terminals 11, 21, 31 provided on the annular conductive bodies 10, 20, 30. The connecting terminals 11 each include a first connecting portion 111 connected to a center conductor 101, a second connecting portion 112 connected to a winding 911 and a coupling portion 110 for coupling the first and second connecting portions 111, 112. The coupling portion 110 includes the first extended portion 114 including an end portion114a extending through a gap between the annular conductive bodies 10, 20, 30 toward one side in an axial direction of the annular conductive bodies 10, 20, 30 and the second extended portion 115 extending from the end portion 114a of the first extended portion 114 toward one side in a radial direction of the annular conductive bodies 10, 20, 30. The second connecting portion 112 is formed at an end portion of the second extended portion 115 on one side in the radial direction.
