Press-fit mounted electrical connector

An electrical connector to be mounted on a printed circuit board, comprising:

• a plurality of plate wafers vertically stacked, each wafer comprising a frame and a plurality of conductive contacts planarly arrayed and secured by said frame, each of said conductive contacts having a mating portion extending forwardly to mate with a complementary mating connector, 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 a first length along said lower edge of the frame;
• an insulating housing defining a front face and an opposite rear face, a plurality of contact receiving slots, and a plurality of engaging portions for securing said plurality of plate wafers, said plurality of engaging portions extending along a second length backwardly from the rear face above said rib of said frame;
• a cylindrical positioning bar;
• wherein said second length does not overlap the first length in a vertical direction, the rib of the frame forming a top face on which a tooling downwardly press;
• 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.

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 in a front-to-back direction;
• 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 lower rib extending over the first length along said lower edge of the frame for a tooling to press on a top face of the lower rib;
• said insulating housing forming a plurality of upper engaging portions extending a second length backwardly from the rear face at a level higher than said rib and engaged with an upper portion of the corresponding plate wafers;
• a cylindrical positioning bar;
• wherein said upper engaging portions are offset from the lower ribs of the corresponding plate wafers in said front-to-back 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.
