Abstract

An electrical connector (1) includes a housing (10), four signal contacts (20), a pair of power contacts (30) and a shielding (40, 50). The housing has a forwardly extending mating tongue (12). The mating tongue defines four receiving channels (126) therein in a vertical direction and a pair of side surface (122). A groove (128) is defined in each of the side surfaces of the mating tongue. Each signal contact comprises a mating portion (21) retained in a corresponding receiving channel. Each power contact comprises a mating portion (31) retained in a corresponding groove of the mating tongue. The shielding substantially surrounds the housing. The connector has a small dimension and can be used in a portable electronic device.

Claims

1. An electrical connector comprising:

an insulative housing, the housing having a forwardly extending mating tongue, the mating tongue defining a plurality of receiving channels in a vertical direction and a pair of side surfaces, a groove being defined in each of the side surfaces; and

a plurality of contacts composed of a plurality of signal contacts and a pair of power contacts, each contact having a mating portion, the mating portion of each of the signal contacts being retained in a corresponding receiving channel, the mating portion of each of the power contacts being retained in a corresponding groove of the mating tongue.

2. The electrical connector as claimed in claim 1, wherein the housing has a rear base and the mating tongue extends forwardly from the rear base, the rear base of the housing defining a plurality of passageways, and each contact comprise a mounting portion extending rearwardly from the mating portion and retained in a corresponding passageway.

3. The electrical connector as claimed in claim 2, wherein the passageways of the rear base comprises a plurality of first passageways communicating with the corresponding receiving channels and a pair of second passageways communicating with the grooves of the mating tongue.

4. The electrical connector as claimed in claim 1, wherein the mating tongue comprises a plurality of retaining block at a front, top corner of the mating tongue, and each signal contact has a retaining end for engaging with a corresponding retaining block.

5. The electrical connector as claimed in claim 1, wherein the mating tongue has an upper surface and a lower surface perpendicular to the side surfaces, and the receiving channels of the mating tongue extend from the upper surface to the lower surface.

6. The electrical connector as claimed in claim 1, wherein the rear base defines a plurality of spacers extending rearwardly therefrom, a plurality of channels being defined between the spacers and the spacers and sidewalls of the housing, and each contact comprises a retaining portion bent downwardly from the retaining portion and retained in a corresponding channel defined by the spacers and the spacers and the sidewalls of the housing.

7. The electrical connector as claimed in claim 1 further comprising a shielding substantially surrounding the housing.

8. The electrical connector as claimed in claim 7, wherein the shielding comprises a first shielding and a second shielding, and the second shielding surrounds a combination of the first shielding and the housing.

9. An electrical connector comprising:

an insulative housing having a mating face, a pair of sidewalls, an upper wall between the pair of sidewalls thus together forming a receiving space, a rear base opposite to the mating face, and a mating tongue integrally extending forwardly from the rear base and beyond the mating face, the mating tongue defining a plurality of receiving channels in a vertical direction and a pair of groove in each side surface of the mating tongue; and

a plurality of contacts composed of a plurality of signal contacts and a pair of power contacts, each contact having a mating portion, the mating portion of each of the signal contacts being retained in a corresponding receiving channel, the mating portion of each of the power contacts being retained in a corresponding groove of the mating tongue.

10. The electrical connector as claimed in claim 9, wherein the rear base defines a plurality of first passageways each communicating with a receiving channel of the mating tongue, and each signal contact has a mounting portion retained in the first passageway.

11. The electrical connector as claimed in claim 9, wherein the rear base further defines a pair of second passageways communicating with the grooves of the mating tongue, and each of the pair of power contacts has a mounting portion retained in the second passageway.

12. The electrical connector as claimed in claim 9, wherein the mating tongue comprises a plurality of retaining block on a front end thereof, and each signal contact has a retaining end for engaging with the retaining block.

13. The electrical connector as claimed in claim 9, further comprising a first shielding and a second shielding substantially surrounding the subassembly of the housing and the first shielding.

14. An electrical connector comprising:

an insulative housing having a forwardly extending mating tongue with a plurality of signal and power terminals therein;

a one piece lower half shield upwardly assembled to the housing from a bottom face of the housing, said lower half shield defining a U-shaped configuration with a resilient engaging tab extending upwardly from a front edge of a horizontal section of said U-shaped configuration and toward the mating tongue; and

a one piece upper half shield rearwardly assembled to the housing from a front face of the housing, wherein

said upper half shield includes a mating frame enclosing a front end portion of said mating tongue therein.

15. The electrical connector as claimed in claim 14, wherein said upper half shield further includes an upward retention portion with a screw hole therein.

16. The electrical connector as claimed in claim 14, wherein said upper half shield defines a top wall with joint edges extending in a front-to-back direction thereof.
