What is the main purpose of the plating process used for connector contact plating?

I. What is the main purpose of plating connector contacts with electroplating process? If you look closely at plated contacts, you will see that the contacts may be small and hard to see, but they are the most important component in any connector, and with their intricate design and shiny plating material, the cosmetic aspect of the contact plating is also embellished. Connector contact plating can serve a variety of purposes. A well plated contact ensures better electrical conductivity of the circuit, and when the base material of the contact is electrically conductive, plating reduces the resistance of the contact itself, which makes it easier for current to flow through the contact. Plating connector contacts also serves a mechanical purpose, as rubbing two pieces of metal together can cause friction and damage, and a layer of plating protects the base metal of the contact underneath. Gold is often used as a plating material for a number of reasons. Not only does it have excellent electrical conductivity, but gold is also a precious metal and does not react with other materials, making it ideal for contact plating. Because gold does not oxidize or tarnish in the atmosphere, it gives it long-term durability in harsh environments.
