Electrical connector with improved tongue

摘要

A receptacle connector for mating with the plug connector, includes an insulative housing and two rows of terminals. The housing includes a main body and a mating tongue forwardly extending from the main body and forming two opposite mating surfaces. Each of the terminals includes a front mating section and a rear mounting section. The mating tongue forms a plurality of passageways to receive the mating sections of the corresponding terminals therein, respectively. The housing further forms a plurality of holes communicatively behind the some passageways in the vertical direction for increase the impedance of the corresponding terminal on the mating sections, respectively.

1. An electrical connector comprising:
an insulative housing including a main body and a mating tongue forwardly extending from the main body in a front-to-back direction and defining opposite mating surfaces thereon in a vertical direction perpendicular to said front-to-back direction; a plurality of contacts disposed in the housing, each of said contacts defining a front mating section and a rear mounting section, said contacts including grounding contacts, power contacts and differential pairs for signals; a plurality of passageways formed in each of the mating surfaces to receive the plurality of contacts; a metallic shielding plate is embedded within the mating tongue at a mid-level; and corresponding passageways of plurality of passageways receiving the differential pairs therein, each corresponding passageway equipped with each hole communicatively located behind the mating section of a corresponding differential pairs in the vertical direction to raise impedance of the mating section; wherein each hole extends with a distance to expose the shielding plate in the vertical direction; wherein the mating tongue forms a plurality of ribs on the mating surfaces to separate the plurality of passageways in a transverse direction perpendicular to both said front-to-back direction and said vertical direction; and wherein the holes extend rearwardly along said front-to-back direction beyond said ribs and also extend to reach a level in the vertical direction, where the metallic shielding plate is located.
