Definitions

  • the invention relates to a pair of electrical connectors, the individual connector elements of which consist of a base material coated with tin or a tin alloy.
  • Connectors usually consist of a socket and plug, which are made from metal strips by forming.
  • the base material used for this is generally given a full or partial surface coating before the forming step, which is intended both to protect the base material from corrosive attack and, if appropriate, to improve the solderability.
  • all metals and metal alloys customary for electrical applications can be used as the base material, with copper and copper alloys being particularly preferred. It is already known to either galvanically coat the strip from the base material with tin, or to apply tin or a tin-lead alloy to the metal strip in a molten bath.
  • the invention has for its object to provide an electrical connector pair of the type mentioned in the preamble of claim 1, which has excellent properties, particularly with regard to low insertion and removal forces.
  • the base material of the single plug element has a surface coating made of an alloy which is applied in a molten manner and which, in addition to tin and optionally lead and small deoxidation and processing additives, also comprises up to a total of 10% by weight of at least one of the elements the group contains silver, aluminum, silicon, copper, magnesium, iron, nickel, manganese, zinc, zirconium, antimony, rhodium, paladium and platinum.
  • the harder surface coating of one of the connection partners of the connector system ensures on the one hand that the insertion and pulling forces or the total insertion forces in a multi-pole connector system - are significantly reduced, on the other hand the harder coating also improves corrosion protection and increases the achievable number of connections / withdrawals.
  • this intermediate layer can have a thickness of 0.1 to 1 ⁇ m.
  • the hardness of the surface coating is increased by adding at least one element which preferably forms mixed crystals or intermetallic phases, for example hume-rothery phases, with tin.
  • the electrical conductivity and in connection with it the contact resistance depend on lattice structures and the crystalline structure of the alloy partner.
  • An ordered structure present in intermetallic phases generally favors the conductivity, while the conductivity is reduced when an alloy is formed.
  • the hardness of alloys is normally higher than the hardness of pure metals.
  • the coating material should be molten at the lowest possible temperatures. It is advantageous if the tin alloy has a melting point of at most 390 ° C. for the surface coating of the metal strip. The melting point should preferably be below 320 ° C.
  • the surface coating of the base material for the individual connector elements consists of a tin alloy which contains 0.1 to 8.5% by weight of at least one of the elements from the group silver, aluminum, silicon, copper, magnesium, iron , Nickel, manganese, zinc, zirconium, antimony, rhodium, palladium and platinum.
  • the tin alloy layer deposited from the molten bath should preferably have a thickness of 0.3 to 12 ⁇ m.
  • an alloy composition was selected which consisted essentially of 1% by weight of silver, 0.03% by weight of phosphorus and the balance of tin including inevitable impurities.
  • a metal strip made of the low-alloy copper alloy CuFe2P was coated with the tin alloy over the entire surface using the hot-melt tinning method.
  • the melt bath temperature was about 250 ° C.
  • Plug sleeves of various known plug systems were produced from the coated metal strip, the coating of which had a microhardness of 1200 N / mm2.
  • the corresponding plugs of the plug systems examined were made from a corresponding metal strip with a surface coating of pure tin.
  • the hardness of the pure tin coating was about 600 N / mm2. Due to the different hardness of the individual connector elements, a reduction of the insertion forces of 20 to 50% compared to a connector system could be achieved with the different connector systems, the connector connection partners of which each had a coating of pure tin.
  • Example 2 An alloy of a tin multi-material system was used to coat the base material mentioned in Example 1.
  • the sample alloy composition contained 5 wt% antimony, 1 wt% copper, 0.5 wt% silver, 0.2 wt% nickel, 0.2 wt% zinc, 0.02 wt% phosphorus and the balance tin .
  • the microhardness of the coatings tested in practice was 1900 Nmm2.
  • Out Plugs of a flat plug connection were produced in the coated metal strips.
  • the corresponding plug-in sleeve or socket of this plug-in connection consisted of a base material with a pure tin coating applied in a molten manner. With this combination, too, there was a reduction in the plug-in force of about 50% compared to a plug-in connection, the individual plug elements of which had a surface coating of pure tin.
