Electrical connector haiving contact wafer equipped with transverse grounding bar

An electrical connector comprising:

• an insulative housing defining a receiving space;
• a connection module received within the receiving space and including a pair of vertical contact modules commonly sandwiched a vertical grounding module therebetween in a horizontal lateral direction,
• each of said contact modules including a plurality of contacts embedded within an insulative contact wafer via an insert-molding, a plurality of grooves formed in the insulative contact wafer
• the grounding module including at least a metallic grounding plate;
• and
• a plurality of grounding bars each received within one corresponding groove;
• wherein
• each grounding bar includes an inward part mechanically and electrically connecting to the grounding plate, and a plurality of outward parts mechanically and electrically connecting to corresponding grounding contacts of the contacts of one contact module.

An electrical connector comprising:

• an insulative housing forming a receiving space;
• a metallic shield enclosing the housing;
• a connection module received within the receiving space and including a pair of vertical contact modules commonly sandwiched a vertical grounding module therebetween in a horizontal lateral direction,
• each of said contact modules including a plurality of contacts embedded within an insulative contact wafer via an insert-molding;
• the grounding module including at least a metallic grounding plate, and grounding contacts of the contacts of both the contact modules electrically connected to the grounding plate via either a plurality of spring fingers unitarily extending from the grounding plate, or a plurality of grounding bars discrete from the grounding plate but located between the grounding plate the grounding contacts of the contacts of both the contact modules and mechanically and electrically connected therebetween;
• wherein
• a metallic fastener is secured to the housing and includes a plurality of fastening pieces to be received within corresponding channels in the contact wafers for securing the connection module to the housing.
