Patent ID: 8011957

Claim:
An electrical connector to be mounted on a printed circuit board, comprising: an insulating housing defining a front face and an opposite rear face, a plurality of contact receiving slot extending through the front and rear face; a plurality of plate wafers vertically stacked behind the insulating housing, each wafer comprising a frame and a plurality of conductive contacts secured by said frame, the plurality of conductive contacts planarly arrayed and each having a mating portion forwardly extending into said insulating housing, a middle portion secured in said frame and a press-fit portion extending downwardly from a lower edge of the frame, the press-fit portions of said plurality of conductive contacts of each wafer disposed along a first length, said frame forming a rib extending over the first length along said lower edge of the frame for a tooling to press on a top face of the rib; a cylindrical positioning bar; wherein said insulating housing forming a plurality of engaging portions extending a second length backwardly from the rear face at a level higher than said rib, said second length not overlapping the first length in a vertical direction; wherein each of the plate wafers forming a slot within a region of the rib; wherein the slot of each plate wafer aligned in a horizontal direction; wherein the cylindrical positioning bar inserted into the slots.
