Patent ID: 8822062

Claim:
A power-supply device comprising: a battery assembly composed of a plurality of batteries each having a positive electrode at one end of the battery and a negative electrode at the other end of the battery, said batteries overlapped with each other in a manner that electrodes having the different polarities are adjacent to each other; a plurality of bus bars connecting the batteries in series by connecting the adjacent electrodes having the different polarities in the battery assembly; and a terminal having an electric contact part attached to each bus bar, and a wire connecting part continued to the electric contact part, and attached to an electric wire connected to a voltage measuring device for measuring a voltage of the battery, wherein the electric contact part of the terminal integrally includes a pair of press-contact terminals being connected by a joint plate, each press-contact terminal having a pair of clipping pieces, each pair of clipping pieces respectively being joined by a joint piece at one end of the clipping pieces, the pair of clipping pieces extending away from the joint piece and being disposed with a gap from each other to receive a bus bar of the plurality of bus bars in the gap, each press-contact terminal being connected to the bus bar by the clipping pieces press-inserting the bus bar in between the gap between the clipping pieces, and wherein the clipping pieces alone contact the bus bar and alone press-insert the bus bar between the clipping pieces, wherein an outermost end of the clipping pieces contacts the bus bar.
