Abstract: Disclosed is an electrical connector of the type fixedly attached to printed circuit boards having the male pins or terminals of the connector designed to go through corresponding bores in printed circuit boards that are then soldered to said board permanently establishing the desired electrical connections and further offering a high degree of resistance to humidity and, consequent humidity caused corrosion in the male pins or terminals through the novel use of ring-like projections around each male pin, stand-off supports, and a insulating and sealing resin filler.
