Pressure piece for contacting an electric lead

The battery pack has several battery flat cells (6) with cathode arrestor (17) and anode conductor (18) that are connected to each other. A conductive tempering element (30) is pressed on arrestor through pressure piece (25) made of glass-fiber reinforced plastic. The pressure surface (40,41) of pressure piece is inclined at an angle (44) with respect to longitudinal center plane of pressure piece.
