Separable High Current Connector Immune To High Vibration

The use non-fretting contact platings such as silver and gold on separable high-current connector contacts is common knowledge. But in high vibration applications, these platings wear off even when lubricated. We have empirically discovered that tin-plated contacts mated to silver-plated contacts, lubricated with a non-fretting lubricant, will not frett and will not have excessive wear even when subjected to high-currents and high mechanical vibrations. Testing has shown that the enhanced electrical performance and reliability of this proposed connector metallurgy arises from the tin-plating in the contact area being replaced by silver plating in the contact area.
