1501808 Electric cell terminal connection VARTA BATTERIE AG 21 June 1976 [25 June 1975] 25689/76 Heading H1B An electric storage cell having a terminal comprising a tubular member having a higher conductivity than lead extending in a leakproof manner through a cover of a cell container 1 and the end of the member within the container being mechanically and electrically undetachably connected to a bridge 2 interconnecting electrode plates of one polarity. The conductor may be a Cu or Al tube 3, may be closed at the end contacting lead bridge 2, may be cast into the bridge and may have lateral extending strips 9 embedded in the bridge 2. The tube may be coated sequentially with a layer of Sn and a layer of Pb 4 and may be coated with a synthetic resin, e.g. polypropylene or polyethylene which is welded to the resin cell cover 5. Alternatively the coated tube may be enclosed in a lead sleeve 6 which itself has a synthetic resin coating 7 which may be interposed between the lead sleeve 6 and the lead coating 4. |
