Patent ID: 7854825

Claim:
An electrical contact mechanism for cathodes and anodes within an electro-refining mechanism comprising: a) a base insulator; b) a cap block insulator having, 1) a first set of recesses on a first side of said cap block insulator, each of said first set of recesses having an opening through said cap block insulator, 2) a second set of recesses on the first side of said cap block insulator, each of said second set of recesses having an opening through said cap block, 3) a third set of recesses on an opposing second side of said cap block insulator, each of said third set of recesses having an opening through said cap block, 4) a fourth set of recesses on the second side of said cap block insulator, each of said fourth set of recesses having an opening through said cap block, 5) an insulating ridge positioned substantially along a center line of said cap block insulator and configured to electrically separate said first and second set of recesses from the third and fourth set of recesses, c) a first electrical connector extending through the openings in the first set of recesses and the openings in the third set of recesses; d) a second electrical connector extending through the openings in the second set of recesses; and, e) a third electrical connector extending through the openings in the fourth set of recesses.
