Silvering touch finger electroplating hanger of circuit breaker

Abstract

The invention relates to a silvering touch finger electroplating hanger of a circuit breaker. The silvering touch finger electroplating hanger of the circuit breaker is characterized in that an electroplating support, an electric conductive assembly and a shielding assembly are included; the electric conductive assembly comprises a stainless steel electric conductive substrate and a plurality of sets of touch finger electric conductive contact sockets which are distributed in the horizontal direction and are arranged on the stainless steel electric conductive substrate; the shielding assembly comprises an insulation shielding plate and insulation shielding plates arranged on the two side faces; all the sets of the touch finger electric conductive contact sockets are respectively provided with a rubber shielding bar and a pressing plate in the horizontal direction. The silvering touch finger electroplating hanger of the circuit breaker has the advantages that circuit breaker touch fingers are placed on all the sets of the touch finger electric conductive contact sockets, the electroplating support, the stainless steel electric conductive substrate, metal springs of the touch finger electric conductive contact sockets and the touch fingers are electrically connected to form a cathode, the cathode is matched with a silvering solution which is used as an anode in an electroplating pool so that electroplating can be realized, then a silvering layer is plated in a non-rubber shielding bar area, local electroplating can be achieved, electroplating cost is lowered, electroplating efficiency can be guaranteed, and the problem of production efficiency restriction caused by local protection impregnation is solved.

Description

technical field [0001] The invention relates to an electroplating rack, in particular to an electroplating rack for silver-plated contacts of a circuit breaker. Background technique [0002] The circuit breaker is one of the main electrical equipment in the substation, which uses the cooperation of contacts and fingers to realize opening and closing. It can not only cut off and connect high-voltage lines and various no-load and load currents when the system is running normally, but also cut off various overload currents automatically, quickly and reliably through the function of the relay protection device when the system fails. and short-circuit current to prevent the occurrence and expansion of the scope of the accident. [0003] During the manufacturing process of the contact finger of the circuit breaker, the two arc-shaped convex parts of the contact finger are the working area, and a layer of silver plating needs to be electroplated on the working area. At present, t...

Problems solved by technology

The disadvantages of this method are: partial dipping protection is difficult, the production efficiency is low, and the production capacity cannot be met when the demand is large.

[0004] It is difficult to use the traditional partial protective dipping to produce, the production efficiency is low, and it cannot meet the assembly capacity. Therefore, the full silver plating process has been adopted, which has virtually caused waste of resources and increased costs.
