ABSTRACT:
This invention relates to electrical connector terminal arrays, having interference canceling characteristics that meet or exceed the performance requirements of Category 5 components. The arrays are suited for producing connectors of the type for mounting to a printed circuit board. The connectors comprise a dielectric housing into which are mounted four pairs of electrical conductors. The conductors are arranged essentially in parallel fashion where the respective one ends thereof are spaced apart a first uniform distance, and the other respective ends thereof are spaced apart a second uniform distance greater than the first uniform distance. The conductors are further characterized by being arranged in a non-contact overlapping arrangement with the respective conductors of each outer pair in a single overlap of each other. The respective conductors of the center pair cross each other and then each crosses the adjacent conductor twice. By this arrangement, for an 8-conductor connector of the plug and receptacle type, the inner pairs of conductors exhibit a NEXT Loss of at least 45.00 at 100 MHz.
