Definitions

  • the present invention relates to an electrical contact which can be used either singly or as part of a switch, a contactor, a relay or a connector.
  • This contact is characterized in that it comprises a male element and a female element in which the male element is mounted sliding with hard friction, an air chamber being formed between the end of the male element and the bottom, of the female element, and in that these two male and female elements are at least partially made of a porous material soaked with an aqueous solution charged with metallic submicronic particles so that, when inserted, this solution constitutes between these elements, a conductive film ensuring the passage of current.
  • the male and female elements are in the form of envelopes containing the aqueous solution.
  • the male and female elements are monolithic and soaked with the solution aqueous.
  • Figures 1 and 2 are views in axial section of these embodiments.
  • the contact according to the invention comprises a male element 1 and a female element 2 in which the element 1 is mounted sliding with hard friction.
  • the male element 1 is constituted by a cylindrical envelope 3 made of porous material, for example ceramic or alumina, which is closed by a capsule 4, carrying a connection wire 5, and contains an aqueous solution 6 containing metallic sub-micron particles , with very high conductivity and very low resistance, the particles having a diameter of 10 to 1000 times smaller than the diameter of the pores of the envelope 3;
  • the female element 2 is constituted by an envelope which comprises a wall 7 of porous material and a metal wall 8 carrying a connection wire 9 and contains a solution 10 similar to the solution 6.
  • the two elements 1 and 2 delimit a chamber 11 filled with air.
  • the contact consists of the male 12 and female 13 elements, which are made of a microporous material having a high coefficient of elasticity and soaked with a viscous compound charged with metallic submicronic particles.
  • the male element 12 is closed externally by a cap 14 carrying a connection wire 15 while the female element 13 is housed in an envelope 16 carrying a connection wire 17. This contact operates as previously described.
  • the male element 12 is pressed into the female element, the air in the chamber 11 is compressed and a conductive film is formed between the elements 12 and 13.
  • the contact according to the invention has no rebounds on closing and no electric arc is established. It works perfectly in VHF because of the skin effect, it has a low contact resistance and responds excellently to micro-currents.
  • An inverter could be produced by providing two contacts and by connecting their male elements to the same control lever so that, when one of the male elements is inserted into its female element, the other comes out of it and vice versa.
