Edge and broadside coupled connector
View Patent ↗An electrical connector comprises two signal contacts, each having an L-shaped body portion, a first contact arm connected to a first end of the L-shaped body portion, and a second contact arm also connected to the first end of the L-shaped body portion. For each signal contact, the first contact arm and the second contact arm define a plug contact receiving space therebetween, and the L-shaped body extends from a first end to a second end opposite the first end. The signal contacts are positioned so that an edge of each of the L-shaped bodies is proximate and opposite the edge of the other signal contact, thereby electrically edge coupling the contacts. The edges of the L-shaped bodies may extend along the entire length of the bodies and along the contact arms, thereby providing electrical edge coupling throughout the length of the contact.
