  • Publication number: 20220021083
    Abstract: A connection module includes a FPC and bus bars connected to the FPC and connecting the electrode terminals of power storage elements that are adjacent to each other. The FPC includes a first wiring portion, a second bus bar mount portion, and a third bus bar mount portion to which the bus bars are connected. The FPC further includes a second expandable/contractable portion and a third expandable/contractable portion. The second expandable/contractable portion is continuous from the second bus bar mount portion and allowed to be expanded and contracted in a direction to be closer to and farther away from the first wiring portion and the third bus bar mount portion. The third expandable/contractable portion is continuous from the third bus bar mount portion and allowed to be expanded and contracted in a direction to be closer to and farther away from the second bus bar mount portion.

  • Publication number: 20220013868
    Abstract: A connection module includes a FPC, bus bars connected to the FPC and connecting the electrode terminals of power storage elements that are adjacent to each other, and a resin protector holding the bus bars and the FPC. The FPC includes a FPC body member and a first deformable portion that connects the FPC body member and the bus bars. The resin protector includes a FPC holding portion to which the FPC body member is fixed, movable bus bar holding portions to which the bus bars are fixed, respectively, and second deformable portions that connect the FPC holding portion and the movable bus bar holding portions. The first deformable portion and the second deformable portion connect the bus bars and the movable bus bar holding portions to the FPC body member and the FPC holding portion, respectively, such that the bus bars and the movable bus bar holding portions are movable with respect to the FPC body member and the FPC holding portion.

  • Publication number: 20210305723
    Abstract: A joint structure includes an end portion of the flat electric wire assembly, a terminal fitting, and solder. The flat electric wire assembly includes a conductive line, a first insulating layer covering the conductive line, and a second insulating layer covering a portion of the conductive line. The terminal fitting includes a joint portion that includes a receiving section on which the end portion is placed and blocking sections extending from the receiving section such that the end portion is between the blocking sections. The first insulating layer includes a first surface opposed to the receiving section and a second surface on which the conductive line is disposed. The conductive line includes an end portion different from the portion covered with the second insulating layer. The solder is disposed over the second surface. The blocking sections include surfaces over which the solder is not disposed.
