EW-LP Series Device Connectors

The EW-LP20 series connectors are designed for high-precision, high-quality automatic insertion. With features such as self-locking device and waterproof and dustproof, it is widely used in various challenging environments.

We all know that the contact is a key structural component of the industrial connector, the main component is a copper alloy, the outer layer of a protective metal plating, then the contact parts why the choice of copper alloy and the need to do the plating process? First of all, we choose copper alloy contact parts instead of using pure copper which is because although pure copper conductivity will be higher but the texture is soft and copper alloy is stronger, more suitable for the use of pins and jacks with each other when a strength requirement.

Why do you need a protective metal layer?

On the one hand, because the copper alloy in the long-term use of easy to oxidation and easy to corrosion and gold plating on the surface can be very good to protect the contact parts, on the other hand, the intermatching contact parts in the operating environment prone to wear and tear problems, because often to plug and unplug, through the plating process to deal with can strengthen the contact parts a contact surface, improve his a wear resistance.

We can see Weichat’s waterproof industrial connector, the use of high-end high-quality copper alloy as the base material of the contact, the contact surface using a high thickness of liquid gold plating surface treatment process to improve the durability and wear resistance of the contact plating, and through this process, our waterproof industrial connector has excellent electrical and thermal conductivity. Our aim is to make the world’s electrical connections safer and more convenient for our customers.
