Abstract

An electrical connector includes a metallic shell defining a mating cavity opening forwards, a terminal module assembly received in the metallic shell, and a shielding plate being located between an upper surface and a lower surface of the terminal module assembly. The terminal module assembly defines a front region exposed in the mating cavity to function as a mating tongue. The terminal module assembly defines an insulator associated with a plurality of contacts with corresponding contacting sections exposed upon opposite upper and lower faces of the mating tongue, the contacts are categorized with differential pairs and grounding contacts. The shielding plate defines a main plate and grounding fingers split from the main plate to directly touch with corresponding grounding contacts. The shielding plate is embedded with the terminal module assembly and the grounding fingers of the shielding plate are fixed with the insulator of the terminal assembly.
