Relationship between service life of automobile connectors and coated metal
In order to extend the service life of automobile connectors, automobile connectors are coated with metal to resist oxidation and wear. Does the gold-plated quality of automobile connectors affect connector life?
The service life of automobile connectors is related to the nature of the coated metal, and the problem of connectors during the course of gold plating will lead to color difference when they are used later.
1. There are impurities in the gold-plated raw materials, which may lead to color difference in the coating metal of automobile connector terminal
When coating material for automobile connector terminals is made, impurities exceeding the tolerance of the plating solution will affect the color and brightness of the gold layer. Organic impurities will make the metal layer dark and bloom phenomenon; Interference with metal impurities can make the coating red or even black.
2. If the plating current density is too high, it will also affect the color difference of automobile connector terminals
When calculating the total area of the plating bath part, if it is wrong, the numerical calculation is wrong, which is larger than the actual surface area, it will cause abnormal gold-plated current flow, so the metal layer is red.
3. The aging of plating solution will also affect the plating results of automobile connector terminals
It is easy to cause excessive accumulation of impurities and abnormal color of gold layer.
In addition, the mutual insertion and extraction during gold plating will easily lead to the coating effect of automobile connector terminals, which will affect the service life of automobile connector.
