Electroplating cathode hanger

Abstract

An electroplating cathode hanger is structurally characterized in that a hanger main body is fixed below a main body upper fixing frame, a conductive block is arranged on one side of the main body upper fixing frame, a mounting groove is formed in the middle of the hanger main body, a conductive sheet is pressed in the mounting groove through a pressing plate, a fluororubber conductive sheet sealing ring covers the upper layer of the conductive sheet, and a groove is formed in the hanger main body; an electric lead is arranged in the groove and sealed and insulated through sealant, one end ofthe electric lead is connected with the conducting strip, the other end of the electric lead is led to the conductive block along the fixing frame on the body, the body cover plate is provided with agroove, an air bag is fixed in the groove in the body cover plate, and a rear cover plate covers the outer side face of the pressing plate and is fixedly connected with the body cover plate. The hanger has the advantages that the hanger main body has an anti-corrosion function, and the strength is ensured; conductive areas of the product are uniformly distributed; liquid medicine can be more effectively prevented from entering the non-plated surface of a product, and the influence on the plating effect of the product due to plating of a plating layer on the conducting strip is avoided; the service life is prolonged; the coating quality is improved; the safety is improved; increasing efficiency and quality.

Description

technical field [0001] The invention relates to an electroplating cathode hanger, in particular to a 2-inch, 4-inch, 6-inch, 8-inch, and 12-inch or 16-inch hanger. Background technique [0002] The function of the electroplating hanger is to hang or fix various products so that they are connected to the cathode. During anodic oxidation and electropolishing, they are connected to the anode to conduct current to the product, so as to form a plating layer (such as copper plating, nickel plating, gold plating, etc.) ) or other processing purposes. Specifically, the plated parts are transferred by means of the hanger, and loaded into the plating tank as a conductor, and the plated parts are connected to the plating solution through the hanger. Nearby electrons are obtained, so that a coating is formed on the surface of the product. [0003] In the whole process of obtaining the coating by reduction on the plated piece, whether the design of the hanger is reasonable or not has ...

AI Technical Summary

Problems solved by technology

[0004] The electroplating hangers in the prior art have the following deficiencies: 1) the non-plated surface of the product is prone to seepage, which leads to the conductive area being easily plated; 2) the conductive contact part has poor contact after being used for a period of time, which will cause the product coating Uneven; 3) The current conduction part is easy to heat and burn, which will cause damage to the main body of the hanger; 4) The back cover is usually sealed by tightening screws, the screws are fragile, and the main body of the hanger is easily damaged, resulting in leakage
