I know this is not a novel topic and I have done some searching and reading*, but I feel like I am still not crispy clear on the best way to apply dielectric grease on different connectors.
For example, for a Z9 Higo over-molded connector, on the male part there are 9 pins, each with about 2 mm of insulation at the bottom. Do I apply the grease around the base of those pins, or up near the tips? Should I envision it sealing the large 8 mm diameter connection or sealing around the individual pins? Would you tend to use it very sparingly, or be pretty generous?
For Anderson and JST I am thinking that one would need to apply a lot to both metal and plastic parts, as AW explains below, focussing on the male side for a JST-sm. Is there a downside to applying too much?
The grease I plan to use is Ancor, dielectric silicone compound, ZZC946.
* "If it helps, the idea behind it is to completely seal out moisture from getting to any of the conductive surfaces or wires or contacts, so essentially "filling up" the connector's airspaces / airgaps is it's job.
If you have "overmolded" connectors like Higo, etc., then just the ends you plug together need it.
If you have "open" connectors like JST, Molex, Tamiya, Anderson, etc., it should go in the entire connector shell so the moisture can't get onto and corrode the crimp or solder area of the contact either, or get into the wire conductors and wick up the wire, corroding it from within.
It doesnt' have to be totally filled...just covering all the conductive surfaces and places water could get in there and sit."
