Abstract
The invention relates to the plating of conductive components by electrolytic deposition. An electroplating device in accordance with the invention comprises at least one electrolytic cell containing a tubular anode and having inlet and outlet connections for a bath of electrolyte flowing longitudinally through the anode. A removable component-holder of the device comprising means for gripping a component for plating, which component holder is electrically connected to a cathode-supply plate and is adapted to be mounted on the cell to close it and suspend the component along the axis of the anode. The device can be used inter alia for plating with hard chromium.
Claims8
An electrolytic plating device which comprises at least one electrolytic cell comprising:
- a tubular anode provided with an opening at its upper end for the introduction into it of the component to be electroplated, and provided at its lower part with an electrolyte inlet connection and at its upper part with at least one electrolyte outlet connection;
- means for causing a flow of electrolyte through said anode via said electrolyte inlet and outlet connections;
- a removable component-holder formed at its upper part with a cylindrical portion coming in tight adjustment with said tubular anode and formed at its lower part with a conical portion for the automatic centering of said component-holder during its introduction into said opening provided at the upper end of said tubular anode;
- a flange at the upper end of said component-holder for covering the upper edge of said tublar anode;
- sealing means between said cylindrical portion of said component-holder and the inner surface of said tubular anode;
- means for gripping said component to be electroplated provided for at the lower end of said conical portion of said component-holder;
- and means for electrically connecting said tubular anode and said component to be electroplated to a source of direct current.
