Claim of US Patent No. 10,498,086

1. An apparatus comprising:a housing;
a first differential pair of signal contacts connected to the housing, where a first contact of the first differential pair of signal contacts has a shorter physical length than a second contact of the first differential pair of signal contacts, where a first air gap having a first physical length and a first physical width is provided in the housing at the second contact to thereby shorten an effective electrical length of the second contact and effectively reduce signal transmission in-pair skew between the first and second contacts; and
a second differential pair of signal contacts connected to the housing, where the first and second differential pair of signal contact are substantially aligned in a common plane, and where the second differential pair of signal contacts comprises:
a third contact and a fourth contact, wherein the third contact of the second differential pair of signal contacts having a shorter physical length than the fourth contact of the second differential pair of signal contacts, where a second air gap having a second physical length and a second physical width is provided in the housing at the fourth contact to thereby shorten an effective electrical length of the fourth contact and effectively reduce signal transmission in-pair skew between the third and fourth contacts;
wherein the first physical length is longer than the second physical length and the first physical width is narrower than the second physical width.
