I have to disagree with Steve to some extent about dielectric grease on
contact surfaces. In any case of moderate to high contact pressure, the
grease will be penetrated easily and the contact will be fine. The grease
will also help to protect the contacts from moisture which can promote
corrosion and reduce the conductivity, especially in the case of dissimilar
metals.
In the case of connectors with very low contact pressure other types of
protective lubricants should be used containing polyphenyl ether.
