    摘要： A bus bar assembly for electrically connecting a plurality of battery cells having electrode leads is provided. The bus bar assembly includes a bus bar support frame having an opening; an insertion bus bar, the insertion bus bar being displaceable relative to the bus bar support frame in the opening; side-adhering bus bars positioned with the insertion bus bar being interposed therebetween to form fitting spaces respectively besides opposite sides of the insertion bus bar so that at least one electrode lead is insertable into each of the fitting spaces; and a support member configured to support the insertion bus bar at a location protruding further from the bus bar support frame than the side-adhering bus bars protrude from the bus bar support frame, the support member being elastically deformable by the insertion bus bar when the insertion bus bar is pressed.

    摘要： Disclosed is a pressing jig for welding an electrode lead located in a lead slit formed at the bus bar to the bus bar in a closely adhered state. The pressing jig includes a first frame having a first distance adjusting unit and a first pressing unit, and a second frame having a second distance adjusting unit facing the first distance adjusting unit and a second pressing unit facing the first pressing unit. The first frame and the second frame are coupled so that a distance between first pressing unit and the second pressing unit is increased when a distance between the first distance adjusting unit and the second distance adjusting unit is decreased, and the distance between first pressing unit and the second pressing unit is decreased when the distance between the first distance adjusting unit and the second distance adjusting unit is increased.
