Electrical connector with shieldingthereof

A receptacle electrical connector comprising:

• an insulative housing defining a rear base and a front mating tongue, the rear base defining a receiving cavity opening rearwards;
• a first terminal module and a second terminals module stacked with each other and commonly received in the receiving cavity, each of the first and the second terminal modules including an insulator associated with therewith a plurality of contacts categorized with differential pairs and grounding contacts mixed up with one another, each of said contacts defining a front contacting section exposed upon the mating tongue, a middle retention section retained in the insulator for being positioned in the receiving cavity, and a rear tail section extending out of the insulator;
• and
• a metallic plate located between the first and second terminal modules, the metallic plate including a front region snugly inserted into the mating tongue, a spring tang mechanically and electrically contacting one of said grounding contacts for grounding and a rear tail section;
• wherein
• one of said first terminal module and said second terminal module forms an aperture to accommodate said spring tang.

An electrical connector for mating with a complementary connector, comprising:

• opposite upper and lower terminal modules stacked with each other in a vertical direction, each of said upper and lower terminal modules including an insulator associated with therewith a plurality of contacts categorized with differential pairs, grounding contacts and power contacts mixed up with one another along a transverse direction perpendicular to said vertical direction for coupling to the plug, each of said contacts defining a front contacting section exposed upon a mating tongue for mating with the plug, a middle retention section retained in the insulator, and a rear tail section extending out of the insulator for mounting to a printed circuit board;
• and
• a metallic shielding plate located between the upper and lower terminal modules and including a spring tang mechanically and electrically contacting a selected grounding contact for grounding;
• wherein
• said shielding plate and said upper and lower terminal modules are configured to allow said shielding plate to be relatively assembled to at least one of said upper and lower terminal modules in only said vertical direction instead of a front-to-back direction perpendicular to both said vertical direction and said transverse direction;
• wherein
• the insulator of one of the upper and the lower terminal modules defines at least one hole into which at least one mounting tab of the shielding plate extends in the vertical direction for retention.
