ABSTRACT:
A connector having a housing with a number of cavities that receive connector pins is conformally coated. A thixotropic, curable material is used to seal-off the cavities at the end where the contact tails for the connector pins emerge from the housing. The sealing material seals off the cavities from the environment but does not extend so far into the cavities that electrically insulates the connector portion of the connector pins. The sealing material is preferably both ultravioletly-curable for rapid curing and heat-curable to cure the material in shadow areas.
