Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating, and in particular relates to an electroplated corrosion-resistant layer used for the surface of a terminal. Background Art

[0002] Electroplating is the process of applying a thin layer of another metal or alloy to certain metal surfaces using the principle of electrolysis. It utilizes electrolysis to deposit a metal film on the surface of metal or other materials, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics. Many coins are also electroplated on the outside. With the popularization of electronic products, their applications are becoming more and more widespread. During use, electronic interfaces are frequently plugged and unplugged. Frequently plugged and unplugged electronic interfaces are subject to greater wear, and worn areas are susceptible to oxidation and corrosion, often resulting in poor electrical contact. To improve wear resistance and corrosion resistance, many electronic interface terminals are now electroplated with a coating that generally includes a wear-resistant layer and an anti-oxidation and corrosion layer.

[0003] In the prior art, in order to achieve the effects of plug-in resistance, wear resistance, and corrosion resistance, the product has to be electroplated with a very thick layer of precious metal, which makes the production cost very high. In addition, the self-repair function of the plating layer is weak when damaged, thereby reducing the service life of the terminal. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide an electroplated corrosion-resistant layer for the terminal surface, so as to solve the problem that in the prior art proposed in the above background technology, in order to achieve the effects of plug-in resistance, wear resistance and corrosion resistance of the product, it is necessary to electroplate a very thick layer of precious metal, which makes the production cost very high, and the self-repair function of the plating layer is weak when damaged, thereby reducing the service life of the terminal.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a corrosion-resistant electroplated layer for the terminal surface, comprising a copper plating layer, a nickel plating layer fixedly connected to the top of the copper plating layer, a gold plating layer fixedly connected to the top of the nickel plating layer, a nickel-cobalt alloy plating layer fixedly connected to the top of the gold plating layer, a self-repairing plating layer fixedly connected to the top of the nickel-cobalt alloy plating layer, a first through groove and a second through groove respectively provided inside the self-repairing plating, microcapsules provided inside the second through grooves, and a wear-resistant layer fixedly connected to the top of the self-repairing plating layer.

[0006] Preferably, a copper core is fixedly connected inside the copper plating layer.

[0007] Preferably, nickel nanocrystals are provided inside the nickel plating layer.

[0008] Preferably, zinc metal is provided inside the first through groove.

[0009] Preferably, a repairing agent is provided inside the microcapsule.

[0010] Preferably, through holes are provided inside the self-repairing coating.

[0011] Preferably, PTFE (polytetrafluoroethylene) particles are arranged inside the wear-resistant layer.

[0012] Preferably, the wear-resistant layer is a rhodium-ruthenium plating layer.

[0013] Compared with the prior art, the present invention provides an electroplated corrosion-resistant layer for the terminal surface, which has the following beneficial effects:

[0014] 1. The utility model provides a nickel coating and a self-repairing coating, and utilizes nanotechnology to develop nano-level nickel nanocrystals, so that the nickel coating has a smaller grain size, thereby providing higher corrosion resistance and wear resistance. The nanostructure can increase the surface area of ​​the coating and improve the bonding strength between the coating and the substrate. Zinc metal and microcapsules are provided inside the self-repairing coating. When the self-repairing coating is damaged, the microcapsules rupture to release a repair agent, which passes through the through hole and reacts with the zinc metal ions in the first through groove to form a new protective layer, thereby improving the self-repairing function of the coating.

[0015] 2. The utility model provides a gold-plated layer and a wear-resistant layer. The gold-plated layer is provided on the surface of the nickel-plated layer by local electroplating. On the basis of ensuring the bonding between the electroplated layers, the gold content can be reduced, saving costs. PTFE (polytetrafluoroethylene) particles are added to the wear-resistant layer to improve the lubrication effect of the wear-resistant layer, reduce friction, and thus improve the wear resistance of the electroplated layer.

[0016] 3. Through these innovative designs, the utility model can significantly improve the performance of the corrosion-resistant layer of the terminal surface electroplating, extend the service life of the terminal, reduce maintenance costs, and adapt to a wider range of application environments.

[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. BRIEF DESCRIPTION OF THE DRAWINGS
