Stacked modular jack

摘要

A stacked modular jack ( 100 ) mounted on a mother printed circuit board includes an insulative casing ( 3 ), a magnetic subassembly ( 2 ) disposed within the casing and an outer shield ( 1 ) enclosing the casing. The magnetic subassembly includes a single molded housing ( 21 ) having a receptacle ( 212 ) forwardly extending from a main body ( 211 ) thereof. A plurality of barriers ( 218 ) are formed in a bottom surface of the receptacle for retaining magnetic coils and transformers. The magnetic subassembly further includes an optional magnetic box liner ( 25 ) defining a plurality of channels ( 255 ) for cooperating with corresponding barriers of the housing for shielding the coils and transformers from other inside components of the modular jack, thereby effectively reducing electromagnetic interference.
