  • Patent number: 5043235
    Abstract: A galvanic battery having band-shaped positive and negative electrodes, and an intermediate band-shaped separator, which are helically wound to develop an electrode structure for mounting within a cylindrical housing having a cell pole sealed and insulated against the housing, includes a connecting element which electrically bridges the gap between the cell pole and the edge of the corresponding electrode band and which is comprised of a contact plate having a branched contact clamp concentrically welded to it, an insulation plate positioned over the contact plate and having a centrally disposed aperture for receiving the branched contact clamp, and a pressure spring placed over the insulation plate so that the contact plate presses on the exposed edge of the corresponding electrode band under the influence of the pressure spring, and so that the cell pole is received within the branched contact clamp.
