CATHODE ELECTRODE PLATE ASSEMBLY AND FASTENING METHOD THEREOF

摘要

The present invention is a cathode electrode plate assembly and a method for assembling the cathode electrode plate that can be assembled by rotating the bush without rotating the coupling ring when assembling the cathode electrode plate, so that the operation is convenient and the damage of the coupling ring is prevented to reduce the cost of parts by reuse. It relates to a cathode electrode plate having an insertion groove formed therein, a bush inserted into the insertion groove of the cathode electrode plate but integrated with a fastening portion thereon, and a coupling ring for fixing the bush by being inserted into the outside of the bush and fastened to the insertion groove It characterized in that it comprises a. In addition, the method for fastening the cathode electrode plate assembly of the present invention includes the steps of assembling a coupling ring outside the bush body of the bush, fastening the bush to which the coupling ring is assembled into the insertion groove of the cathode electrode plate, and Positioning an insertion ring on the upper side to couple with the bush, passing the fastening portion of the bush through the insertion portion of the upper electrode plate on the upper side of the cathode electrode plate to make the upper electrode plate in close contact, and fixing the upper electrode plate on the fastening portion of the bush. And fixing the cathode electrode plate and the upper electrode plate by fastening the member.
