CONNECTOR WITH TOP- AND BOTTOM-STITCHED CONTACTS

To help maintain and improve signal integrity, a connector housing can include one or more of the following: asymmetric keying features, asymmetric alignment features, and alternating stitched contacts. First and second contact rows and third and fourth contact rows can each have a first row pitch, and the second and the third contact rows can have a second, greater row pitch. First and second keying structures can be positioned non-symmetrically about both longitudinal and median centerlines of the connector housing. If first, second, third, and fourth contacts all lie on a common centerline of the connector housing, the first and the third contacts can be inserted in a first direction, and the second and the fourth contacts can be inserted in a second, opposite direction. First and second contact securing structures can engage the connector housing at different heights of the connector housing.
