Abstract

An electrical connector includes an insulative housing defining a mating cavity, two parallel and stacked mating portions respectively forwards extending into the mating cavity, sets of contact retained in the housing and a grounding member retained in the housing. The first mating portion defines thereon a first surface; the second mating portion spaces from the first mating portion and defines thereon a second surface opposite to the first surface. The sets of contact include a first set of contacts each defining a contacting section exposed upon the first surface and a second set of contacts each defining a deflectable cantilevered beam accessible from the second face. The grounding member is disposed between the first and second mating portions to reduce the cross-talk between the first and second sets of contacts.

Claims

1. An electrical connector, comprising:

an insulative housing defining a mating cavity;

a first mating portion forwards extending into the mating cavity and defining thereon an first surface;

a second mating portion forwardly extending into the mating cavity and spaced from the first mating portion, the first and second mating portions disposed parallel to each other and arranged in a stacked manner, and the second mating portion defining thereon a second surface opposite to the first surface;

a first set of contacts each defining a contacting section exposed upon the first surface;

a second set of contacts each defining a deflectable cantilevered beam accessible from the second face; and

a grounding member disposed between the first and second mating portions.

2. The electrical connector as described in claim 1, wherein the first mating portion unites with the second mating portion to provide a tongue portion of the electrical connector.

3. The electrical connector as described in claim 1, wherein a receiving slot is provided between the first and second mating portions and the grounding member is retained in the receiving slot.

4. The electrical connector as described in claim 3, wherein the grounding member defines a main section and a leg section bending from the main section, the main section is retained in the receiving slot and the contacting sections and the deflectable cantilevered beams are respectively disposed at two opposite sides of the main section.

5. The electrical connector as described in claim 4, wherein the main section is disposed parallel to the first and second surfaces and spaced from the contacting sections and the deflectable cantilevered beams.

6. The electrical connector as described in claim 5, wherein the first mating portion defines a third surface opposite to the first surface, the second mating portion defines a fourth surface facing to the third surface, and the main section is sandwiched by the third and fourth surfaces.

7. An electrical connector compatible to standards of Universal Serial Bus (USB) and External Serial Advanced Technology Attachment (eSATA) protocols, comprising:

an insulative housing defining a base portion, a pair of sidewalls respectively extending forwards from two opposite ends of the base portion and a tongue portion disposed between the sidewalls and defining thereon first and second surfaces opposite to each other;

an eSATA contact set comprising several contacts each defining a blade contacting section exposed upon the first surface and a leg section;

a USB contact set comprising several contacts each defining a deflectable cantilevered beam accessible from the second surface; and

a grounding member retained in the tongue portion and disposed between the eSATA contact set and the USB contact set, and further spaced from the blade contacting sections and the deflectable cantilevered beams.

8. The electrical connector as described in claim 7, wherein the tongue portion defines two opposite side surfaces facing to the sidewalls, a front face connecting with the side surfaces and a receiving slot running through the side surfaces and the front face thereof to divide the tongue portion into first and second mating portions spaced from each other in a stacked manner, and the grounding member defines a main section received in the receiving slot and disposed between the first and second mating portions.

9. The electrical connector as described in claim 8, wherein the main section is retained in the receiving slot with two outmost side edges respectively exposed upon the corresponding side surfaces and a front edge hidden in the receiving slot without any portion extending beyond the front face.

10. The electrical connector as described in claim 9, wherein the grounding member further defines a leg section bending from the main section.

11. The electrical connector as described in claim 10, wherein the main section is disposed between the first and second surfaces and parallel to the first and second surfaces.

12. The electrical connector as described in claim 11, wherein the eSATA contact set has seven contacts including two pairs of differential pairs and three grounding contacts arranged at opposite sides of the differential pairs.

13. An electrical connector comprising:

an insulative housing defining a mating port with therein a forwardly extending mating tongue defining opposite first and second faces thereon;

a plurality of first contacts disposed in the housing and defining stiff contacting sections exposed upon the first face;

a plurality of second contacts disposed in the housing and defining resilient contacting section exposed upon the second face;

a grounding contact embedded into the mating tongue between the first face and the second face;

wherein

the housing defines a plurality of spaced standoffs formed on a rear region of the first face of the mating tongue, and the first contacts are respectively exposed in corresponding gaps between said spaced standoffs.

14. The electrical connector as described in claim 13, wherein the mating tongue defines two opposite side surfaces each connecting with the first and second faces, a front face connecting with the side surfaces and a receiving slot running through the side surfaces and the front face thereof to divide the mating tongue into first and second mating portions spaced from each other in a stacked manner, and the grounding contact defines a main section received in the receiving slot and disposed between the first and second mating portions.

15. The electrical connector as described in claim 14, wherein the main section is retained in the receiving slot with two outmost side edges respectively exposed upon the corresponding side surfaces and a front edge hidden in the receiving slot without any portion extending beyond the front face.

16. The electrical connector as described in claim 15, wherein the grounding contact further defines a leg section bending from the main section.

17. The electrical connector as described in claim 16, wherein the main section is disposed between the first and second surfaces and parallel to the first and second surfaces.
