Abstract:
A method of reducing signal cross talk during coupling in a connector for the transfer of balanced electrical high frequency signals, the method comprising providing a connector comprising contact springs (5) and terminals (4) as well as first and second non-co-axial pairs of first and second conductors (A+, Aâˆ’), (D+, Dâˆ’) arranged in an insulation member (9) to connect the contact springs (5) and the terminals (4) for respectively transferring the balanced signals, whereinthe conductors (A+, Aâˆ’), (D+, Dâˆ’) of each of the pairs are respectively in two spaced layer, and an effective permittivity âˆˆrâˆ’1 between the first conductor (A+) of the first pair of conductors (A+, Aâˆ’) and the first conductor (D+) of the second pair of conductors (D+, Dâˆ’) is different from an effective permittivity âˆˆrâˆ’2 between the second conductor (Aâˆ’) of the first pair of conductors (A+, Aâˆ’) and first conductor (D+) of the second pair of conductor (D+, Dâˆ’), wherein one of the effective permittivities comprises a notch in the insulation member all along the conductors.
