Rubber and metal composite electric contact and preparation method thereof

The invention discloses a rubber and metal composite electric contact and a preparation method thereof. The rubber and metal composite electric contact is a circular layered complex which is formed bytightly combining a metal sheet layer with a plurality of through holes and a rubber layer through heat vulcanization molding and has a thickness of 0.1-5 mm and a diameter of 1-15 mm, no isolation layer is arranged between the rubber layer and the metal layer of the electric contact, no excessive glue exists on the outer surface of the metal layer, in the rubber and metal composite type electriccontact, the rubber and the metal are firmly combined, the overall strength of the electric contact is adjustable, and the electric contact has good dust resistance, so that the electric contact hasstable and reliable electric conduction performance. The invention also discloses a preparation method of the rubber and metal composite electric contact, wherein the method overcomes the traditionaltechnical prejudice, is simp
