Abstract

Abstract A high speed, high density electrical connector. The connector is assembled from wafers. Each wafer is formed by molding a first dielectric housing over a shield plate. Signal contacts are inserted into the first dielectric housing and a second housing is overmolded on the first housing. Features are employed to lock the first and second housings together with the shield plate to provide a mechanically robust subassembly. The connector as formed has a good electrical properties, including precise impedance control and low cross talk.
