Connector having grounding bar connecting to both shielding shell and grounding layers of wires

An electrical connector assembly comprising:

• an insulative housing extending along a longitudinal direction and includes a pair of opposite side walls extending along the longitudinal direction, and a pair of opposite end walls at ends of the side walls to cooperate with the side walls commonly forming a mating cavity forwardly exposed to an exterior in a front-to-back direction perpendicular to the longitudinal direction;
• a plurality of passageways formed in each of the side walls so as to form two rows of contacts in the housing;
• a metallic shielding plate retained in the housing and between two rows of contacts in a vertical direction perpendicular to both the longitudinal direction an the front-to-back direction;
• a metallic shielding shell enclosing the housing;
• a plurality of contacts disposed in the corresponding passageways, respectively, each of the contacts including a front contacting section exposed in the mating cavity and a rear connecting section exposed outside of the housing;
• a cable sub-assembly located behind the housing including:
• two rows of wires corresponding to the two rows of contacts, each of said wires including an inner conductor, an inner insulator, an outer conductor and an outer insulator sequentially and coaxially arranged with one another;
• a pair of inner grounding bars corresponding two rows of the wires and mechanically and electrically connected to the outer conductors of the wires;
• and
• a pair of outer grounding bars corresponding two rows of wires and mechanically and electrically connected to the outer conductors of the wires opposite to the corresponding inner grounding bars, respectively, in the vertical direction;
• wherein
• the shielding plate is located between the pair of inner grounding bars in the vertical direction, and between the pair of outer grounding bars in the vertical direction as well.
