Patent number: 10920821Abstract: [Problem] To provide a terminal securing device the size of which can be reduced. [Solution] When a key lock 7 is positioned in a second position a key 6 and the key lock 7 are arranged at overlapping positions in the lengthwise direction of a rod 3, so a portion of a space for displacing the key lock 7 from the second position to a first position can be provided at a position overlapping the key 6 in the lengthwise direction of the rod 3. Thus, an increase in the size of a holder 4 in the lengthwise direction of the rod 3 can be avoided, so the size of the terminal securing device 1 can be reduced.Type: GrantFiled: July 24, 2018Date of Patent: February 16, 2021Assignee: CHUO HATSUJO KABUSHIKI KAISHAInventors: Kenta Imai, Shinji Okamoto, Seiji Yamada
