Abstract
Abstract This invention provides shielded and wireless connectors for interconnecting electronic circuit boards that are stacked in metal carriers. Serial interconnectors through the carriers provide transmission line paths through the stacked layers through connector assemblies embedded in and fed through each carrier in collinear alignment with each other. Each of the embedded feed through connector assemblies has upper and lower button connectors interconnected by a metal conductor, all positions within an axial hole formed by a pair of substantially cylindrical dielectric inserts. The upper and lower button connectors protrude from the upper and lower surfaces of the upper and lower adjacent circuit boards, respectively. This invention provides connector assemblies having the ability to withstand very high inertial forces without degradation of the electrical contact with the metal pads of the respective circuit boards.
