Flippable electrical connector

Abstract

A receptacle connector includes an insulative housing defining a base and a mating tongue, with a widen and thicken step structure around a root thereof adjacent to the base; two rows of contacts disposed in the insulating housing with contacting sections exposed upon the mating tongue and mount tails out of the base; a metallic shield surrounding the mating tongue so as to define a mating cavity; and a metallic bracket attached the shield. The first wall of the shield defines a pair of spring tangs split therefrom and extending rearwards into the mating cavity, the second wall defines a pair of dimples protruding inwards the mating cavity for holding the plug connector. The bracket covers spring tangs and seals any opens defined on the first wall for keeping integrity therewith under EMI consideration.

         2 . The receptacle connector as claimed in  claim 1 , wherein the end walls defines spring tangs split therefrom and extend rearwards into the mating cavity, and the metallic bracket includes a pair of endwalls covering the spring tangs and sealing corresponding opens on the endwalls. 
     
     
         3 . The receptacle connector as claimed in  claim 1 , wherein the metallic bracket defines mounting tails extending from the endwalls thereof for mounting to the printed circuit board. 
     
     
         4 . The receptacle connector as claimed in  claim 1 , wherein the metallic shield defines mounting tails extending from rear sides of the end walls thereof. 
     
     
         5 . The receptacle connector as claimed in  claim 1 , wherein the metallic shield further includes a rear wall with two ears latched to two opposite end walls of the shield. 
     
     
         6 . The receptacle connector as claimed in  claim 6 , wherein the rear wall of the metallic shield further defines mounting tails. 
     
     
         7 . The receptacle connector as claimed in  claim 1 , comprising a shielding plate embedded in the insulating housing, wherein the shielding plate comprises a front horizontal portion in the mating tongue and the base and a rear vertical portion extending out of the base and between two rows of the mounting tails of the contacts. 
     
     
         8 . The receptacle connector as claimed in  claim 1 , wherein a front edge of the metallic shield is equipped with a plurality of flared flanges for easy insertion of the plug connector. 
     
     
         9 . A vertical type receptacle connector for mounting on a printed circuit board, comprising:
 an insulative housing comprising a lower base and an upper mating tongue extending from the base;   a metallic shield enclosing the insulative housing; and   a metallic bracket surrounding an upper side of the metallic shell;   wherein the shield forms a plurality of spring tangs via corresponding cutouts defined thereon, the metallic bracket covers and seals the spring tangs and the corresponding cutouts for keeping integrity therewith under EMI consideration.   
     
     
         10 . The vertical type receptacle connector as claimed in  claim 9 , wherein a bottom portion of the metallic shield is split to outwardly extend and form a relative large gap exposing the insulating housing, a horizontal extension is unitarily formed on the bottom portion of the metallic shield to cover the gap mostly. 
     
     
         11 . The vertical type receptacle connector as claimed in  claim 9 , wherein the metallic bracket is a one-piece ring. 
     
     
         12 . A right angle type receptacle connector for mounting on a printed circuit boards, comprising:
 an insulative housing defining a rear base and a front mating tongue forwardly along a front-to-rear direction, the mating tongue defining a widen and thicken step structure around a root thereof adjacent to the rear base;   a row of upper contacts and a row of lower contacts disposed in the insulating housing with contacting sections exposed upon the front mating tongue and mount tails from the rear base;   a shielding plate embedded in the insulating housing; and   a metallic shield retained around the base and surrounding the mating tongue so as to define a mating cavity between the metallic shied and the mating tongue, the mating cavity and the contacts being arranged in a diagonally symmetrical arrangement;   wherein the shielding plate comprises a front horizontal portion located in the mating tongue and the base and between the contacting sections of the two rows of contacts, a rear vertical portion extending out of the base and between the mounting tails of the upper and lower contacts.   
     
     
         13 . The right angle type receptacle connector as claimed in  claim 12 , wherein the shielding plate further defines two mounting tails extending from opposite lateral ends of the rear vertical portion thereof for mounting to the printed circuit board. 
     
     
         14 . The right angle type receptacle connector as claimed in  claim 12 , wherein the shielding plate further defines a pair of spring arms extending from the front horizontal portion and goes across the rear base to mechanically and electrically connect to the metallic shield. 
     
     
         15 . The right angle type receptacle connector as claimed in  claim 12 , wherein the shielding plate is manufactured with the insulating housing via an inserting mold process, and the upper and lower contacts are assembled into the insulating housing after the inserting mold process.
