Electrical connector with a grounding bar connecting the terminals of a plurality of ground contact wafers and shielding braids of cables

An electrical connector comprising:

• a plurality of signal contact wafers and a plurality of grounding contact wafers alternately arranged with each other along a transverse direction;
• each of the signal contacts wafer including a pair of upper contacts and a pair of lower contacts integrally formed with an insulative housing, said housing forming a first U-shaped configuration in a side view so as to form a first receiving slot therein, by two sides of said slot said pair of upper contacts and said pair of lower contacts being respectively spaced from each other in a vertical direction perpendicular to said transverse direction;
• each of said grounding contact wafers including a pair of contacts integrally formed with an insulative block, said block forming a second U-shaped configuration similar to said first U-shaped configuration in a side view to form a second receiving slot therein by two sides of which said pair of contacts are respectively located in the vertical direction, said second receiving slot being aligned with said first receiving slot in the transverse direction;
• and
• a plurality of upper cables and a plurality of lower cable mechanically and electrically connected to the corresponding pair of upper contacts and the corresponding pair of lower contacts, respectively.
