Patent number: 11031724Abstract: An object is to provide a technique by which a space in a vehicle in which a wire harness including a plurality of splice circuits is arranged can be reduced and good manufacturability at the time of manufacture can be achieved. A stacked connector is formed by joining a plurality of split connectors to each other. The split connectors each include a split connector housing provided with a plurality of terminal receiving chambers and a plurality of terminal-equipped electric wires that each include a terminal received in the terminal receiving chamber and an electric wire to which the terminal is connected. At least one of the split connector housings is provided with a locking portion having a protruding shape that protrudes outward to be capable of locking the terminal-equipped electric wire received in the split connector housing of a joining counterpart.Type: GrantFiled: March 9, 2017Date of Patent: June 8, 2021Assignee: SUMITOMO WIRING SYSTEMS, LTD.Inventors: Susumu Hiei, Kenta Itou, Takehiro Nakata, Kohei Yamaguchi, Yuichi Nakamura, Daisuke Fukai, Masaki Mizushita, Motohiro Yokoi, Kohei Takagi

Patent number: 10224647Abstract: A wire with terminal includes a wire in which a core is covered with a coating, and a terminal 20 including a wire barrel 24 to be crimped to the core exposed from the coating of the wire and an insulation barrel 26 to be crimped to the coating of the wire. The wire is pulled rearwardly from the terminal. Recesses 26B are provided on a surface of the insulation barrel 26 to be crimped and openings of the recesses 26B are shaped to become narrower toward a rear side. As the wire is pulled more rearwardly, the coating penetrating into the recesses 26B moves rearwardly of the recesses 26B to be compressed and hardened and becomes less likely to come out of the recesses 26B. Thus, impact strength can be enhanced.Type: GrantFiled: February 16, 2016Date of Patent: March 5, 2019Assignees: AutoNetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Hiroshi Hamada, Satoshi Morikawa, Takehiro Nakata, Takuji Otsuka, Takanobu Shimada
