Abstract
A connector with at least two pairs of contacts is provided, wherein crosstalk between first and third contacts, which are separated by a second contact, is reduced by a lateral extension of the third contact. The lateral extension includes a suppressing section extending parallel and adjacent to the first contact, and a pair of connecting sections that each connects one end of the suppressing section to the rest of the third contact. This allows at least some current passing along the third contact, to pass through the suppressing section and induce anti-crosstalk currents in the first contact to counter crosstalk. At least one connecting section has a lengthening portion that increases its length to create a phase shift. The suppressing section has a minimal width compared to its height. For a stamped sheet metal contact, the width is less than twice the height to reduce capacitive coupling while maintaining inductive coupling.
