Abstract

Abstract A controlled impedance connector assembly comprised of a mutually engageable plug and receptacle for termination of coaxial cable leads in a manner which enables rapid attachment to and detachment from a user board of a very large number of signal leads while ensuring an acceptable level of controlled impedance from the coaxial cable to the user board. The receptacle includes a backup plate and a plurality of metallized grounding segments fixed to the backup plate and having a plurality of spaced parallel terminal receiving bores therein extending between opposed surfaces. An insulation plate is fixed to each grounding segment and overlies one of the surfaces. A plurality of pin contacts are fixed to the insulation plate such that a head member extends into an associated terminal receiving bore and an oppositely directed tail member is adapted for termination at available circuitry. The plug includes a frame mounting a plurality of dielectric segments each having a plurality of parallel spaced terminal receiving bores extending between a front and rear face. The dielectric segments are floatingly mounted for movement within defined limits in directions transverse to the axes of the terminal receiving bores. A terminal mounted to the extremity of each of a plurality of coaxial leads is removably received in an associated terminal receiving bore with a locking spring being utilized to prevent inadvertent removal of a terminal but subject to purposeful manipulation to enable removal of the terminal. Each bore of the grounding block receives and retains a barrel spring for frictionally holding a terminal in place engaged with the lead member of a pin contact. In another embodiment, a plurality of side by side dielectric strips replace the single insulative plate and permit soldered connections between the pin contacts and stripline cable at a location remote from the receptacle. When the heat employed in soldering the connections has dissipated, the strips are then attached to a one piece grounding block thereby avoiding harm of other components by reason of the heat. The dielectric strips are shaped to enable termination of a high density of stripline cables without causing undue interference between neighboring cables.
