Abstract: A modular plug having an insulative housing comprising a front wall, a rear wall, a top wall, a bottom wall and a pair of lateral walls perpendicularly interposed between the top two bottom walls. There are a number of longitudinal terminal receiving slots in the front and top wall. There is a cable receiving cavity in the rear wall. A number of conductors means extend from the rear wall of the jack to adjacent to a different one of the said pin receiving slots. There are also a number of metallic contacts, and each of the contacts is adjacent to a different one of the terminal receiving slots and is connected to a different one of the conductors. At least one of the contacts has a different shape from at least one of the other contacts. A surprising and unexpected reduction in cross talk is achieved.
