Patent ID: 7837492

Claim:
An electrical connector comprising: an elongate insulative housing having a horizontal mounting surface and a vertical rear face; and a plurality of conductive contacts received in the insulative housing and each comprising a contacting portion horizontally inserted through said rear face, an engaging portion extending to said mounting surface, and a vertical extension portion electrically connecting with the contacting portion and the engaging portion, wherein said extension portion is thinner and shorter than said contacting portion, said extension portion has a node that is wider than other portions of the extension portion, said node is adapted for making the characteristic impedance of the conductive contact matching demand; a positioning portion is disposed in the insulative housing corresponding to the node for cooperating with the node to restrict movement of the node; and wherein the node of the extension portion of the conductive contact defines a through hole in a middle thereof and the positioning portion of the insulative housing disposes a protrusion corresponding to the through hole, the protrusion being inserted to and being retained in the through hole.
