Abstract

1461474 Electrical connectors FULMER RESEARCH INSTITUTE Ltd 3 Oct 1975 [3 July 1974] 29552/74 Heading H2E [Also in Division C7] An electric connector comprises a conductive substrate bearing a plating of gold alloy up to 5Á thick, the alloy containing 0À1-5% by wt. of Cd, Sb or Sn. The substrate may be Cu, a Cu alloy, Cu-Ni-Fe, brass, steel or Ni and may include Ni plated on Cu. The alloy is electroplated conventionally and exhibits increased corrosion and substrate-diffusion resistance. Cu substrates may be degreased, cathodically cleaned in cyanide and etched with a sulphochromic etch (for Cu base) or with HCl (when a Ni plating is present). Reference is made to the insertion and separation of connectors.
