Circular waterproof connectors play a crucial role in enabling power and signal transmission, with their contact components serving as direct channels. One key aspect of these connectors is the contact component, which is primarily made of copper alloys and coated with a layer of protective metal. In this blog post, we will explore the reasons behind using copper alloys for contact components and the importance of applying a protective metal coating.
Why Copper Alloys Instead of Pure Copper?
The choice of copper alloys for contact components is not primarily driven by the cost of pure copper, but rather by the mechanical strength requirements. While pure copper offers higher conductivity, it is relatively soft in terms of its physical properties. Copper alloys, on the other hand, provide enhanced strength, making them more suitable for meeting the mechanical requirements of plug-and-socket compatibility.
The Significance of Protective Metal Coating:
There are two primary reasons for applying a protective metal coating on the contact components:
Protection Against Oxidation and Corrosion:
Over time, copper alloys are prone to oxidation and corrosion. By coating the surface with less reactive metals like gold, the contact components’ base metal is effectively shielded from corrosion.
Enhanced Durability and Wear Resistance:
Contact components that mate with each other can experience micro-frictional wear in operational environments. Additionally, the act of plugging and unplugging may lead to mechanical wear. Applying a coating through the plating process reinforces the contact surfaces, improving wear resistance and ensuring long-term stability in both mechanical and electrical performance.
Introducing the BD Series Industrial Connector by Shine Industry Electric:
To ensure long-term high reliability of contact components, Shine Industry Electric’s BD Series industrial connectors employ high-quality copper alloys as the base material for contact components. These components are further treated with a thick layer of nickel under a gold plating surface.
The nickel underlayer enhances the durability of the precious metal contact plating, with gold being an excellent choice for contact plating material. Through this plating process, the BD Series contact components exhibit outstanding electrical conductivity, heat dissipation, wear resistance, and corrosion resistance. These qualities ensure that the BD Series contact components possess exceptional adaptability and durability in harsh working environments.
