Abstract

See full text

An electrical connector according to the invention may include a first signal contact that defines a first side and a first edge, wherein the first side is greater in length than the first edge, the first edge having a first edge width, and a second signal contact that defines a second side and a second edge, wherein the second side is greater in length that the second edge, the second edge having a second edge width. The first signal contact and the second signal contact may be positioned edge-to-edge. A gap may be defined between the first edge of the first signal contact and the second edge of the second signal contact. The gap may have a gap width that is approximately equal to at least one of the first edge width and the second edge width. The connector may have a column pitch, and the gap width may be based on the column pitch. The gap width may be approximately 0.3-0.4 millimeters.
