<p>Means for providing an electrical connection between adjacent cells in an electrochemical accumulator battery through an opening in a cell wall made of plastic material.</p><p>In a joint (10) consisting of a screw (32) passed through concentric openings (16, 28, 30) in the leg (24, 26) of each plate group bus (20, 22) and in the cell wall (18) and a nut (34) holding the joint together, each leg (24, 26) is arranged tightly against the cell wall (18). Around the screw (32) there ist arranged in the openings (16) in the cell wall an annular spacer (36) of greater external diameter than the openings in the legs and with a thickness smaller than that of the cell walls and made of a harder material than the cell walls.</p> |
