Abstract
Abstract A miniaturized high-denisty coaxial interconnect system for use in termination of coaxial signal cables to electrical signal transmission systems is provided. The system contains one or more grouper modules having a staggered array of receptacle grooves in which the grouper modules are housed within a grouper frame. The system is easy to assemble and provide easy attachment and detachment from the transmission system. This invention also provides for an increased density of signal cables with improved spacing due to the unique design of component parts and their arrangement within the system.
