ABSTRACT The present invention is directed generally to electri- cal connectors for providing interconnection between one or more printed circuit board panels and external electrical com- ponents. When connectors are used under severe environmental conditions, printed circuit boards and their associated con- nectors must be coated with insulating liquids. These liquids, however, are able to seep or wick into small crevices and apertures. The present invention provides an improved con- nector not subject to wicking and seepage, as is the case with prior art connectors. According to the invention, there is provided an electrical connector comprising a one-piece plastic body member having a main body portion, first and second exterior surfaces, and a plurality of spaced-apart, contact-receiving apertures extending between the surfaces. Each aperture has a narrow cavity region and a shoulder cavity region communicating with the narrow cavity region and cooperating therewith to define an offset shoulder surface. Electrical contacts are disposed in the apertures, each con- tact including a terminal portion, a shoulder portion and an active contact portion. Each portion of the contact is shaped to correspond to the configuration of the correspond- ing cavity region in the connector, whereby the press fit of the terminal portion, the shoulder portion, and a plurality of raised ridges provided on the terminal portion of the contact define an irregular constricted and circuitous path through the aperture to provide an essentially liquid imper- vious juncture.
