Abstract
The present invention provides a structure of an electric contact of an electrolytic cell, wherein an elongated conductive member is provided as a bus bar 10 on a wall of an electrolytic cell for feeding current to anodes 1 and cathodes 2 arranged in the electrolytic cell; the conductive member 10 forms a convex portion 12 in parallel with the longitudinal direction on the upper surface of an elongated plate member 11 forming a base; and at least the upper surface of the convex portion 12 is totally or partially gold plated 13 in the longitudinal direction.
Claims17
A structure of an electric contact of an electrolytic cell, wherein an elongated conductive member is provided as a bus bar on a wall of an electrolytic cell for feeding current to anodes and cathodes arranged in the electrolytic cell;
- said conductive member forms a convex portion in parallel with the longitudinal direction on the upper surface of an elongated plate member forming a base;
- and at least the upper surface of said convex portion is totally or partially gold-plated in the longitudinal direction.
A structure of an electric contact of an electrolytic cell, wherein side bus bars and connecting conductors for electrically connecting the individual bus bars are provided along the side wall of electrolytic cells for electrically connecting neighboring electrolytic cells;
- at electric contacts between said side bus bars and said connecting conductors, any of the contact surfaces of at least any one of them is gold-plated;
- and said bus bars and said connecting conductors are secured.
A structure of an electric contact of an electrolytic cell, wherein a crossbar is provided for suspending an electrode arranged in the electrolytic cell therefrom and for electrically connecting a bus bar or a side bus bar and the electrode;
- and at least the ends of the crossbar which come into electrical contact with the bus bar or the side bus bar are gold-plated.
A structure of an electric contact of an electrolytic cell, wherein a bus bar or a side bus bar is provided on a wall of an electrolytic cell for feeding current to anodes arranged in the electrolytic cell;
- and each of said anodes is gold-plated at least at a portion in electrical contact with said bus bar or said side bus bar.
