Connector greases from Nye Lubricants

Why should electrical contacts be lubricated?

Reduction of friction

A thin film of lubricant can reduce mating force by as much as 80 percent, an important factor in connector assembly. For electronic connectors with dozens or even hundreds of pins, or for automotive connectors that are in hard-to-reach places, a low insertion force makes assembly more efficient and ensures solid connections.

Protection against oxidation

Lubricants guard against oxidation and the effects of harsh environments. With gold-plated connectors this means protection against substrate corrosion. Thin gold plating can be microscopically porous; and a thin film of lubricant can seal the pores, prevent substrate attack and assure low contact resistance.

Preventing fretting corrosion

In addition to atmospheric corrosion, tin/lead connectors are also subject to fretting corrosion, which is mainly caused by vibration and shock. Fretting corrosion continually exposes fresh layers of metal surface to oxidation. A lubricant film minimizes metal-to-metal contact during vibration, protecting the connector from metal wear.

Advantages of lubricating electrical components
