Abstract: A shielded electrical connector is formed by the mating of upper and lower housing covers and is used with twisted pair cables, each of which includes a pair of signal wires and a drain wire enclosed within an outer insulation. Each pair of terminated signal wires is disposed in a contact module which is positioned in one of a plurality of shielded compartments formed between adjacent separating walls extending from the outer housing covers when the covers are mated with each other. Each of the separating walls has a positioning slot into which a positioning rib on the contact modules may be disposed in order to properly position and retain the contact module in one of the shielded compartments. A ferrule assembly is crimped about the end of the insulation of each of the cables and is coupled to the drain wire of the twisted pair cable.
