Abstract
An electrical connector is disclosed particularlity for use between a printed circuit board and another electrical component. A body member of dielectric material is provided having first and second exterior surfaces and a plurality of spaced-apart, contact-receiving apertures extending therethrough between the surfaces. Each aperture has a narrow cavity region, a shoulder cavity region, and a wide cavity region extending seriatim from the first to the second exterior surfaces. A plurality of electrical contacts are disposed in respective ones of the apertures, each contact including a terminal portion press-fit within the narrow cavity region, a shoulder cavity region, and an active contact portion extending into the wide cavity region for connection to another electrically conductive element. The press-fit of the terminal portion and the shoulder portion and the raised ridges between the contact and aperture together define a substantially irregular and constricted path through the aperture from the wide cavity region to the first exterior surface to provide an essentially liquid impervious passage. The active contact portion comprises a pair of spaced parallel prongs disposed within a long dimension of the wide cavity region, and oppositely disposed semi-cylindrical regions are provided intermediate the ends of the long dimension to accommodate a generally cylindrical male contact member inserted into the aperture.
