Abstract: In an improved connector assembly, a male pin (112) is inserted into a proximal end of a female contact which (110) conductivity engages the pin at a distal end, providing a folded signal path geometry. As a signal propagates in a first direction alone the male pin (112), it generates a first magnetic field of a first orientation about the male pin (112). At the contact point, the signal reverses direction and generates a second magnetic field of a second orientation opposite the first orientation about the female contact (110). Their respective opposed orientations cause the magnetic fields to substantially cancel in the region of magnetic interaction. Any remaining electronic fields are contained by grounded shielding in the female contact (110) cavities, for example in the form of chambers with conductivity coated walls surrounding the contacts. This configuration mitigates the effect of crosstalk between adjacent signals in the connector, and reduces the effective path length of the signal.
