The invention relates to a cathode conductive seat for electroplating, a cathode conductive device for electroplating, and electroplating equipment. The electroplating equipment comprises the cathode conductive device. The cathode conductive device comprises the cathode conductive seat and a cathode conductive rod. The cathode conductive seat comprises a V-shaped seat and elastic jaws, wherein the upper end of each elastic jaw extends and crosses the sidewall, adjacent to the corresponding elastic jaw, of the V-shaped seat along a horizontal direction; and a friction head used for forming friction with the cathode conductive rod is arranged on each elastic jaw. When the cathode conductive rod is installed downwards on the V-shaped seat, an oxidation rust layer on the cathode conductive rod falls off due to the mutual friction between the friction head on each elastic jaw, and the cathode conductive rod, thus maintenance for the good electrical conductivity of the cathode conductive device is promoted; and in addition, the contact between the upper end of each elastic jaw and the cathode conductive rod is equivalent to the addition of contact points of the cathode conductive seat and the cathode conductive rod, and due to the newly-added contact points, improvement for the electrical conductivity of the cathode conductive device is also promoted.
