Electrical connector with shielding means for grounding and impedance metching

An electrical connector comprising:

• an insulative housing defining a plurality of passageways and shielding holes arranged among the passageways;
• a plurality of electrical contacts receiving in the passageways and comprising a plurality of signal contacts and grounding contacts;
• a plurality of metal posts filled in the shielding holes and electrically connected with the grounding contacts;
• and
• a pair of conductive coverings provided on opposite surfaces of the insulative housing and electrically connecting the metal posts and the grounding contacts, said signal and grounding contacts projecting out the conductive coverings while said metal posts are located within the pair of conductive coverings.

An electrical connector comprising:

• an insulative housing defining a plurality of passageways and shielding holes arranged among the passageways;
• an interior covering provided on a top surface of the insulative housing;
• an exterior covering provided on a top surface of the conductive covering;
• a plurality of electrical contacts receiving in the passageways and comprising a plurality of signal contacts and grounding contacts;
• and
• a plurality of conductive elements received in the shielding holes and electrically connected to the grounding contacts via conductive paths provided by the exterior covering, said conductive elements being insulated from the signal contacts.
