Patent number: 11888250Abstract: A terminal-equipped wire is provided with a wire including a conductor, a terminal to be connected to the conductor, and a shell to be mounted on the terminal. The terminal includes a grip portion for sandwiching the conductor. The shell includes a pressing portion for pressing at least a part of the grip portion toward the conductor. The grip portion has a Sn—Ni alloy layer. The Sn—Ni alloy layer includes locally projecting protrusions. The protrusions bite into the conductor.Type: GrantFiled: August 5, 2020Date of Patent: January 30, 2024Assignees: AUTONETWORKS TECHNOLOGIES, SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Takahito Jo, Yasushi Saito, Tomoyuki Sakata, Masaaki Tabata, Teruo Hara, Shunya Takeuchi, Hideki Matsunaga, Keisuke Teramoto

Patent number: 11843194Abstract: A terminal-equipped electric wire includes an electric wire that includes a conductor, a terminal connected to the conductor, and a shell attached to the terminal. The conductor has a nominal cross-sectional area of 0.13 mm2 or less. The terminal includes a grip portion that pinches the conductor. The shell includes a pressing portion that presses at least a portion of the grip portion toward the conductor. At least one of the conductor and the grip portion includes a tin layer, and an oxide coating formed on the surface of the tin layer. An adhering portion formed of a portion of tin contained in the tin layer that passes through the oxide coating and pours out onto a surface of the oxide coating. The adhering portion has an area of 0.100 mm2 or more.Type: GrantFiled: August 5, 2020Date of Patent: December 12, 2023Assignees: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takahito Jo, Yasushi Saito, Tomoyuki Sakata, Masaaki Tabata, Teruo Hara, Shunya Takeuchi, Hideki Matsunaga, Keisuke Teramoto, Hiroshi Kobayashi, Takeshi Amakawa
