In an improved connector assembly, a male pin is inserted into a proximal end of a female contact which conductively engages the pin at a distal end, providing a folded signal path geometry. As a signal propagates in a first direction along the male pin, it generates a first magnetic field of a first orientation about the male pin. 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. Their respective opposed orientations cause the magnetic fields to substantially cancel in the region of magnetic interaction. Any remaining electric fields are contained by grounded shielding in the female contact cavities. This configuration mitigates the effect of crosstalk between adjacent signals in the connector, and reduces the effective path length of the signal.

Dans un ensemble connecteur amélioré, une fiche mâle est insérée à l'intérieur de l'extrémité proximale d'un contact femelle qui met en contact conducteur la fiche mâle à une extrémité distale, établissant une géométrie de trajet des signaux à repli. En se propageant dans une première direction le long de la fiche mâle, un signal induit un premier champ magnétique ayant une première orientation autour de la fiche mâle. Au point de contact, le signal se propage en sens inverse et induit un second champ magnétique ayant une seconde orientation opposée à la première orientation autour du contact femelle. Ces orientations respectives opposées font que les champs magnétiques s'annulent sensiblement dans la zone d'interaction magnétique. Tout champ électrique restant est contenu par un écran mis à la terre dans les cavités du contact femelle. Une telle configuration atténue l'effet de diaphonie entre signaux adjacents dans le connecteur et réduit par ailleurs la longueur de trajet effective des signaux.
