  • Patent number: 7682192
    Abstract: An electrical coupler includes a connector receptacle having multiple modules. The modules each include a pair of signal conductors and a ground plane or shield, held together by a dielectric module body. The shields are between the pairs of conductors in adjacent modules, and provide electrical shielding between the pairs of signal contacts of different modules. The signal conductors and the shields may be coupled to a board, such as a circuit board. The receptacle may be an angled receptacle, such as a right angle receptacle. The signal conductors of each pair in the receptacle may have a predetermined amount of skew, having different effective electrical lengths. This may allow signal paths through the receptacle and the board to have a combined electrical path that is substantially the same for the signal conductor pair of one of the modules.
