Abstract

A connector assembly is provided having a receptacle connector mateable with a header connector. The assembly includes an insulated housing and a plurality of terminal modules mounted to the insulated housing. The terminal modules have an insulated molded body enclosing multiple connector contacts having opposed mating portions. The terminal module further includes receptacle contacts and leads connected thereto for carrying signals through the terminal module. A differential shell is mounted to the terminal module and has an open sided chamber formed therein. The differential shell includes walls that define the chamber and receive the receptacle contacts. Each chamber includes an open front and open rear ends and includes at least one open side. Each chamber accepts a corresponding receptacle contact through the open side thereof. The walls of the differential shells have non-linear contours that substantially conform to a contour of the receptacle contacts to reduce the air gap therebetween and reduce the impedance of the terminal contact, thereby improving signal performance.
