The invention relates to a cell connector (6) for a battery, especially for absorbing, in conjunction with at least one damping element (9), the vertical forces that are caused by the impact of shocks. The cell connector (6), at one end, is connected to the positive or negative electrodes (4, 5) which are received in a housing (2) having a housing cover (3), and, at the other end, comprises at least one terminal (7, 8) projecting from the housing cover (3). The aim of the invention is to elastically dampen the electrode plates (4, 5) of an accumulator (1) which are disposed inside a housing (2). For this purpose, a terminal (6) having a supporting shoulder (11), integrally molded thereto, is used in the housing (2), a damping element (9), disposed between the housing cover (3) of an accumulator (1) and the cell connector (6), coming to rest thereon. The forces caused by the impact of shocks are passed from the cell connector (6) into the damping element (9) and from the at least one damping element (6) into the housing cover (3) via large-area plane faces (30, 31), said cover being fixed to the housing (2). This measure allows to elastically cushion the electrode plates (4, 5) inside the housing (2). For this purpose, the at least one damping element (9) has corresponding large dimensions and is adapted to receive higher vertical forces. The invention also allows the terminals (7, 8) to move in relation to the housing cover (3) if there is a movement of the electrode plates (4, 5) in relation to the housing (2).

A pole bridge according to claim 4, wherein the parallel planar faces of the at least one damping element are at least partially lubricated with silicon grease. 11. A pole bridge according to claim 4, wherein the at least one damping element has a height of 40 to 80 mm. 12. A pole bridge according to claim 4, wherein the at least one damping element includes a first support surface with an area of 3,000 to 4,000 mm2, and a second support surface with an area of 5,000 to 7,000 mm2. 13. A pole bridge according to claim 4, wherein the cell lid comprises a recess on its outside for a seal ring, which is disposed in disk shape in the recess, and through which the terminal protrudes to the outside, wherein a metal disk rests on the seal ring, and is clamped by means of the safety pins, which are disposed in the provided recesses of the terminal. 14. A pole bridge element according to claim 4, wherein a seal ring is provided as a second seal element, which has height of 25 to 40 mm. 15. A pole bridge according to claim 14, wherein a second damping element is slid onto the terminal from above. 16. A pole bridge according to claim 14, wherein the seal ring includes a diameter of 50 to 70 mm. 17. A pole bridge according to claim 4, wherein the terminal includes copper. 18. A pole bridge at least one damping element according to claim 4, wherein the pole bridge and, in particular, a portion of the support shoulder is clad with lead. 19. A pole bridge according to claim 4, wherein the terminal is at least partially clad with lead. 20. A pole bridge according to claim 4, wherein the terminal is clad with lead up to the elevation of the lid.
