ABSTRACT:
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 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 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 at the tips of the conductors and insulating film faces located in the vicinity thereof are flush with each other or the exposed portions 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 of a rotary electric machine such as an AC generator for a vehicle could be improved.
