Patent number: 7948140Abstract: 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.Type: GrantFiled: October 19, 2009Date of Patent: May 24, 2011Assignee: Hitachi, Ltd.Inventors: Takeshi Sakai, Yoshimi Mori, Yasuhiko Kimura, Masahiko Honma, Fuminori Ishikawa
