The relationship between the service life of automotive connectors and the plating metal
In order to extend the service life of automobile connectors, automobile connector manufacturers will plate metal on the surface of the connector to resist oxidation and wear and extend the service life. Will the gold plating quality of automotive connectors affect the life of the connector?
The relationship between the service life of automotive connectors and the plating metal
The service life of automotive connectors is related to the nature of the plated metal, and problems with the connector during the gold-plating process will cause color differences in subsequent use.
1. Impurities in the gold-plated raw materials will cause color difference in the plating metal of the car connector terminal
In the production of automotive connector terminal plating solution materials, impurities exceeding the tolerance of the gold plating solution will affect the color and brightness of the gold layer. Organic impurities will make the metal layer appear dark and blooming; the interference of metal impurities will make the coating red or even black.
2. If the gold plating current density is too large, it will also affect the color difference of the car connector terminal
When calculating the total area of the plating bath parts, if the value is calculated incorrectly, and the surface area is larger than the actual surface area, the gold plating current will be abnormal, and the metal layer will be red.
3. The aging of the gold plating solution will also affect the gold plating results of the automotive connector terminals
If the gold plating solution is used for too long, it is easy to cause excessive accumulation of impurities in the plating solution and cause the color of the gold layer to be abnormal.
In addition, mutual plugging and unplugging during gold plating can easily lead to the plating effect of the automotive connector terminals, which in turn affects the service life of the automotive connector.
