D-Sub, D-Shaped Connectors - Contacts, referred to as D-Sub contacts, as the core component of D-shaped connectors, are key components for connecting electronic signals or power sources. D-Sub contacts are typically made of highly conductive materials, such as copper alloys, with a surface coated with gold or tin to enhance corrosion resistance and conductivity. They are precisely designed and installed inside the socket or plug of the connector, achieving signal transmission or power connection between circuits through tight insertion. The design principle of D-Sub contacts ensures good electrical contact and mechanical stability, and can maintain long-term reliable connections in harsh working environments. Its characteristics include high conductivity, low contact resistance, wear resistance, and good plug-in durability.
