JY series-Circular Electrical Connector Manufacturers

What is the purpose of electroplating (such as gold plating, silver plating, nickel plating, etc.) on the metal parts of JY series-circular electrical connectors? How to perform surface treatment to improve the aesthetics and protective performance of connectors?
1. The purpose of electroplating treatment
The primary purpose of electroplating metal parts is to improve the electrical conductivity of the connector. Gold plating, silver plating and other precious metal layers have excellent electrical conductivity, which can significantly reduce contact resistance and improve current transmission efficiency, thereby ensuring the stable operation of the connector under high frequency and high power conditions. Especially in high-end fields such as aerospace and nuclear energy, the conductive performance of connectors is extremely demanding, and electroplating treatment is particularly important.
Connectors often face complex and changeable environments during use, such as high temperature, high humidity, salt spray, etc. These harsh environments can easily cause metal parts to corrode and rust. Through electroplating treatment, a dense protective film can be formed on the metal surface to effectively isolate external corrosive media and extend the service life of the connector. For example, the nickel plating layer has good corrosion resistance and can significantly improve the weather resistance of the connector.
During the plugging and unplugging process of the connector, friction and wear will occur between the metal parts. Electroplating treatment can form a layer of higher hardness coating on the metal surface, such as hard chromium plating, thereby improving the wear resistance and hardness of the connector, reducing wear during the plugging and unplugging process, and extending the service life of the connector.
In addition to the above functional purposes, plating can also improve the aesthetics of the connector. By choosing platings of different colors and glosses, such as gold plating, rose gold plating, etc., the connector can be given a more refined and high-end appearance to meet the aesthetic needs of specific occasions.
2. Surface treatment process
Before electroplating, metal parts must be pre-treated. This step includes degreasing, rust removal, pickling, etc., aiming to thoroughly clean the metal surface, remove oil, oxides and other impurities, and lay a good foundation for the uniform adhesion of the electroplating layer. HENGLIAN uses advanced automated cleaning equipment to ensure stable and reliable pre-treatment quality.
The electroplating process is to place metal parts in a plating tank containing electroplating solution, and deposit a required layer of coating on the metal surface through electrolysis. HENGLIAN uses advanced electroplating equipment and technologies, such as pulse electroplating, cyanide-free electroplating, etc., to ensure that the coating thickness is uniform, dense, and environmentally friendly. At the same time, the company also strictly controls the composition, temperature, pH value and other parameters of the electroplating solution to optimize the electroplating effect.
After electroplating is completed, post-processing is required. This step includes cleaning, passivation, drying, etc., aiming to remove residual electrolyte, impurities, etc. during the electroplating process, while improving the stability and corrosion resistance of the coating. HENGLIAN uses an efficient and environmentally friendly post-processing process to ensure that the surface quality of connectors reaches the highest standards.
3. The role of electroplating treatment in improving the aesthetics and protective performance of connectors
Through electroplating treatment, the surface of connector metal parts can show different colors and lusters, such as gold, silver, chrome, etc., thereby significantly improving the aesthetics of the connector. This improvement in appearance not only satisfies users' aesthetic needs for the product, but also enhances the overall quality of the product.
The electroplating treatment forms a dense protective film on the surface of the connector's metal parts. This film can effectively isolate external corrosive media and prevent the metal parts from being oxidized and corroded. The coating also has good wear resistance, hardness and other physical properties, which can reduce wear and scratches during the plugging and unplugging process and extend the service life of the connector. Electroplating treatment can also improve the conductivity and electromagnetic compatibility of the connector, ensuring its stable operation under high-frequency and high-power conditions."
