摘要： An object of the invention is to reduce a stress on an insulating coating on a conductor segment for a stator coil. The conductor segments are bent simultaneously by a head bending apparatus and leg bending apparatus, both provided with a respective disc guide member for guiding the inner most conductor segments along the circumferential direction. Particularly, the disc guide member 16b (for example, may have a permanent magneto built-in) is fixed at the lower surface of the stator core 1. The disc guide member 16b almost touches the inner circumferential surface of the larger segment 331. During bending the tip of the leg portions 33c on the bending jig 543, the disc guide member 16b prevents the leg portions 33c of the larger segments 331 from inclining toward the inner radius direction, thereby bending and extending the linear portions 33c along the circumferential direction.

摘要： An object of the present invention is to improve electrical insulation between a small conductor segment and large conductor segment which forms stator coils inserted into slots of stator core of a driving motor for a automobile vehicle. The axial length of the curved head 3a' is made shorter than that of the curved head 3a. Further, the distance "d" between the border point "c" (the border point between the curved head 3a and legs 3b) and border point "c' " (the border point between the curved head 3a' and legs 3b') is made greater than the difference between the contraction quantity due to bending of the large segment 331 and that of the small segment 332. Thus, the contracted head 3a' (relatively displaced toward the legs) can stay inside the head 3a, thereby improving the electrical insulation between the small conductor segment and large conductor segment.

摘要： Joint Structure of Electric Wire, Stator of Rotary Electric Machine, Method for Manufacturing the same
When electric wires (joint conductors) are disposed adjacent each other in a peeled state of coatings, a gap corresponding to the total thickness of both conductors' insulating films as skin layers is formed between end joined face portions 1H, 2H of the conductors. The gap becomes larger because the conductors are tapered. Therefore, the adhesion between both conductors is impaired, with a consequent fear of occurrence of joining imperfection. In opposed joined face portions 1H, 2H of electric wires (joint conductors), the conductors are deformed from the tips of their axes to the joined face side in such a manner that exposed portions 1A, 2A at the tips of the conductors and insulating film faces located in the vicinity thereof are flush with each other or the exposed portions 1A, 2B are projected. The gap formed between the electric wires (joint conductors) can be diminished, whereby the reliability of connection is improved and it becomes easier to perform the work of joint conductors, with the result that the productivity of a stator 160 of a rotary electric machine such as an AC generator for a vehicle could be improved.
