USB connector assembly having reduced mating height

Claim 2

A plug connector comprising: a dielectric housing having a main body, a front body extending forwards from said main body, and a mating tongue extending forwards from said front body, said dielectric housing defining a plurality of passageways therein; a plurality of terminals accommodated in corresponding passageways of the dielectric housing; and an upper shield enclosing the dielectric housing, said upper shield having a rear section enclosing said main body and a front section extending from said rear section, dimensions of said front section being smaller than those of said rear section, said front section having an inverted U-shaped portion at a front end thereof and a rear portion connecting with said rear section, said inverted U-shaped portion defining a receiving passage therethrough for receiving said mating tongue and said rear portion defining a channel communicating with said receiving passage for receiving said front wherein dimensions of the mating tongue are smaller than those of remaining parts of the first housing.

Claim 3

The plug connector as described in claim 1 , further comprising a lower shield engaged with said upper shield for enclosing the dielectric housing from a bottom side thereof.

Claim 4

The plug connector as described in claim 1 , wherein said rear section of the upper shield defines an engaging groove communicating with said receiving passage and said channel for receiving said main body of the dielectric housing therein.

Claim 5

An electrical connector assembly comprising: a first connector including a dielectric first housing defining a first body with a first tongue forwardly extending therefrom, said first tongue defining two opposite first mating and backing faces thereon; a plurality of first contacts received in said first housing and extending in said first tongue; a first metallic shield generally enclosing said fist housing; a second connector including a dielectric second housing defining a second body with a second tongue forwardly extending therefrom, said second tongue defining two opposite second mating and backing faces thereon; a plurality of second contacts received in said second housing and extending in said second tongue; a second metallic shield generally enclosing said second housing; wherein when mated, from a cross-sectional view the first mating face and the second mating face engage each other with the corresponding first contacts and second contacts mechanically and electrically engaged with each other, under a condition that all of a front portion of the first shield is only sandwiched between said first backing face and said second shield.

Claim 6

An electrical connector assembly comprising: a first connector including a dielectric first housing defining a first body with a first tongue forwardly extending therefrom, said first tongue defining two opposite first mating and backing faces thereon; a plurality of first contacts received in said first housing and extending in said first tongue; a first metallic shield generally enclosing said fist housing; a second connector including a dielectric second housing defining a second body with a second tongue forwardly extending therefrom, said second tongue defining two opposite second mating and backing faces thereon; a plurality of second contacts received in said second housing and extending in said second tongue; a second metallic shield generally enclosing said second housing; wherein when mated, from a cross-sectional view the first mating face and the second mating face engage each other with the corresponding first contacts and second contacts mechanically and electrically engaged with each other, under a condition that all of a front portion of the first shield is only sandwiched between said first backing face and said second shield.
