Patent number: 8784129Abstract: Attaching work of a high-voltage cable is improved. In an electric cable connecting construction of battery packs, the high-voltage cable is connected to conductors held in resin busbar modules for connection with the general electrodes by fastening crimp terminals to the conductors. Two ribs are formed on each of the busbar modules where the crimp terminal is held therebetween to limit an entrained rotation of the crimp terminal. A difference between a gap of the two ribs on one of the adjacent battery packs and a width of the crimp terminal connected to the general electrode is set to a first gap dimension L3 and A difference between a gap and a width of the crimp terminal connected to the general electrode of the other of the adjacent battery packs is set to a second gap dimension L6 larger than the first gap dimension.Type: GrantFiled: January 25, 2013Date of Patent: July 22, 2014Assignees: Yazaki Corporation, Toyota Jidosha Kabushiki KaishaInventors: Shigeyuki Ogasawara, Takao Syouji, Akito Toyama, Shinichi Yanagihara, Michio Ota, Takenori Tsuchiya
