Abstract
1488220 Capacitors SIEMENS AG 4 June 1975 [27 June 1974 (2) 26 March 1975] 24012/75 Heading H1M In a capacitor comprising electrodes in the form of metal coatings 3, 5 separated by dielectric 4 and covering layers 1, 6 to protect the exposed surfaces of the metal coatings, of which covering layer 1 is substantially integrally keyed to the capacitor assembly whereas layer 2 is more loosely united, e.g. where lead wires are connected to the electrodes as described in Specification 1,393,829, the less exposed metal layer is apparently the more affected by corrosion due to atmospheric moisture. To minimize corrosion, an adhesive layer 2 of polyphenylene oxide is provided between covering layer 2 and electrode 3, the dielectric layer is selected from polystyrene, polycarbonate and polysulphone and the adhesive layer is keyed thereto through pores in the electrode coating. To construct the assembly, on covering layer 1, preferably polyethylene terephthalate, as a base is deposited the adhesive layer in solution, optionally containing a hardening adhesive components followed by electrode layer 3 by vapour deposition, dielectric layer 4 as a lacquer and metal layer 5 by vapour deposition. Metal layer 5 may be protected from corrosion by a coating of insulating liquid, e.g. polyisobutylene, silicone, polybutene, polyether, polyisobutylene ether, optionally diluted with halogenated hydrocarbons, e.g. 1,2,2-trifluorotrichloroethane, and possibly in a solvent such as benzene, chloroform, toluene or xylene which is subsequently expelled. The insulating liquid may contain petroleum jelly or mixtures thereof with hard wax. Instead of liquid suitably plastic waxes, e.g. ozoberite or oberin.
