Abstract

A stacked jack modular jack assembly is comprised of a multi-port housing, and a plurality of modular jack subassemblies. The jack subassemblies include upper and lower jack housings sandwiching therebetween, a cross-talk shield. The terminal subassembly is substantially Z-shaped, which allows for increased space there below for signal conditioning components. The terminal module also includes a center shield and a lower shield, and an outer shield, all of which are commoned together and grounded. An outer shield substantially surrounds the entire assembly, and is commoned to the other shield members.
