Abstract

A receptacle connector includes an insulative housing defining a base and a mating tongue extending with a step portion defined at a root region of the mating tongue; a plurality of contacts disposed in the insulative housing with contacting sections exposed upon a first surface and a second surface of the mating tongue and categorized with signal contacts, power contacts and grounding contacts; a shielding plate embedded with the mating tongue and forming a pair of locking edge in two opposite lateral side edges; and an EMI collar intimately surrounding the step portion, the collar comprising two long portions covering the first surface and the second surface of the step portion and two short portions connecting with opposite ends of the long portions. A lateral rigid finger extends straight from a side of the shielding plate and touch an inner side of a short portion of the collar.

Claims

1. A receptacle connector comprising:

a housing defining a base and a mating tongue extending from the base, the mating tongue defining a step portion at a root region of the mating tongue;

a plurality of contacts disposed in the housing with contacting sections exposed upon a first surface and a second surface of the mating tongue and categorized with signal contacts, power contacts and grounding contacts;

a shielding plate embedded with the mating tongue and forming a pair of locking edges in two opposite lateral side edges thereof and exposed upon two opposite sides of the mating tongue;

a one-piece EMI collar intimately surrounding the step portion, the collar comprising two long portions covering a first surface and a second surface of the step portion and two short portions connecting with opposite ends of the long portions;

wherein a lateral rigid finger extends straight from a side of the shielding plate and touch the short portion of the collar.

2. The receptacle connector as claimed in claim 1, wherein a rear finger extends straight from the side of the shielding plate and touches an inner side of a shielding shell surrounding the housing, the rear finger is located behind the lateral rigid finger.

3. A receptacle connector comprising:

an insulative housing defining a base and a mating tongue extending from the mating tongue, the mating tongue defines a thickened step portion at a root region of the mating tongue;

a plurality of contacts disposed in the insulative housing with contacting sections exposed upon a first surface and a second surface of the mating tongue;

a shielding plate embedded with the mating tongue and forming a pair of locking edges in two opposite lateral side edges and exposed upon two opposite sides of the mating tongue;

an EMI collar intimately surrounding the step portion, the collar comprising two long portions covering a first surface and a second surface of the step portion and two short portions connecting with opposite ends of the long portions;

wherein a lateral rigid finger unitarily extends straight from a side of the shielding plate and mechanically connects with an inner side of the short portion of the collar.

4. The receptacle connector as claimed in claim 3, wherein a rear finger unitarily extends straight from the side of the shielding plate and mechanically connects with an inner side of a shielding shell surrounding the insulative housing, the rear finger is located behind the lateral rigid finger.

5. The receptacle connector as claimed in claim 3, wherein each of the longer portions defines two spring tabs elastically pressing against corresponding grounding contacts.

6. The receptacle connector as claimed in claim 5, wherein the spring tabs extend forwards.
