Precautions For Gold Plating Of Heavy-duty Connectors

When heavy duty waterproof electrical connectors pins or sockets that cannot be gold-plated are gold-plated, if the outer surface thickness of the plating layer reaches or exceeds the specified thickness, the inner hole of the punch hole will be plated, or the socket will be very thin, or even have no gold plating layer.

To ensure that the heavy duty 2 pin connector socket has a certain degree of flexibility when plugging and unplugging, most types of heavy duty connector 16 pin sockets are designed with a slit at the opening. During the electroplating process, the parts being plated are constantly flipped, and some heavy duty connector 5 pin sockets are interlocked at the opening, causing the heavy duty connector 6 pin power lines of the inserted parts to shield each other, making electroplating inside the hole difficult.

During gold plating, the plated parts are connected end-to-end. For some types of heavy duty electrical contacts, in the pin design, the outer diameter of the pin is slightly smaller than the diameter of the wire hole. During the electroplating process, some pins will form end-to-end connections. The result is that the heavy duty industrial connector wire hole cannot be gold plated. Both of these phenomena are more likely to occur during vibration gold plating.
