Abstract:
An electrical connector used for electrically connecting a land grid array integrated circuit (IC) module to a printed circuit board (PCB) comprising:an insulative housing defining a first surface adapted to carry the IC module, a second surface adapted to connect with a substrate of the PCB, and a plurality of passageways communicating the first and the second surfaces; a plurality of contacts interferentially received in the passageways, each passageway receiving two contacts therein; wherein each Passageway receives two contacts of same structure therein and the two contacts are opposite to each other; wherein the Passageway is centrosymmetric and is bounded by two first walls, two second walls and two third walls; wherein the first wall is opposite from the third wall and the two second walls align with each other; wherein one first wall and a third wall opposite from the first wall define a first cavity therebetween, the two second walls define a second cavity therebetween and the other third wall and the other first wall define a third cavity; wherein the passageway further is bounded by two centrosymmetric steps therein; and wherein the passageway further comprises two centrosymmetric guiding slots therein.
