Abstract

The present invention discloses an electrical connector comprising: a housing; a base body having a tongue, whose one surface is disposed with a plurality of first terminal slots and whose other surface is disposed with a plurality of second terminal slots; a first terminal assembly whose each first terminal is disposed with a leg and a contact portion slightly perpendicular to the leg, respectively, with the legs being alternately arranged; and a second terminal assembly whose each second terminal is disposed with a leg and a contact portion slightly perpendicular to the leg and then bending downward, respectively.

Claims

1. An electrical connector, comprising:

a housing having a receiving space;

a base body received in the receiving space and disposed with a tongue, whose one surface is disposed with a plurality of first terminal slots and whose other surface is disposed with a plurality of second terminal slots;

a first terminal assembly having a plurality of first terminals, which are received in the first terminal slots, respectively, and which are disposed with a leg and a contact portion slightly perpendicular to the leg, respectively, with the legs being alternately arranged; and

a second terminal assembly having a plurality of second terminals, which are received in the second terminal slots, respectively, and which are disposed with a leg and a contact portion slightly perpendicular to the leg and then bending downward, respectively.

2. The electrical connector as defined in claim 1, wherein the housing is made of metal, whose two sidewalls are formed to a first opening, respectively, from which a retaining portion is formed by bending inward.

3. The electrical connector as defined in claim 1, wherein the two sides of the base body are disposed with a guide slot, respectively, whose one end is formed to have a stopper and which guides the retaining portion to be fixedly retained at the stopper.

4. The electrical connector as defined in claim 3, wherein the guide slot may be formed to have a restricting portion near the stopper, which may accommodate the retaining portion as well as prevent the retaining portion from moving backward.

5. The electrical connector as defined in claim 1, wherein the bottom of the two sidewalls of the housing is further disposed with at least a welding piece on each side, which may be further connected onto a printed circuit board to enhance the retaining strength.

6. The electrical connector as defined in claim 1, wherein the first terminal assembly may be the terminal assembly of e-SATA and some first terminals of the first terminal assembly may be alternately arranged in a top/bottom fashion with respect to other first terminals.

7. The electrical connector as defined in claim 1, wherein the first terminals at the top may be power terminal or ground terminals and the first terminals on the bottom may be signal terminals.

8. The electrical connector as defined in claim 1, wherein the second terminal assembly may be the terminal assembly of USB (Universal Serial BUS) or IEEE 1394 and the other ends of the contact portions are bended upward to form a stopping portion, respectively, and the legs of the second terminal assembly may be located inside with respect to the legs of the first terminals.

9. The electrical connector as defined in claim 1, wherein the plurality of the first terminals includes ground terminal and signal terminals, and the plurality of the second terminal assembly includes ground terminal, signal terminal, and power terminal.

10. The electrical connector as defined in claim 9, further comprising a ground piece, which may be embeddingly inserted at the gap of the tongue and whose front end extends downward to form a contact portion to further contact with one of the ground terminals of the terminal assemblies described above to achieve the function of grounding and electrostatic discharge (ESD) prevention.

11. The electrical connector as defined in claim 10, wherein the two sides of the ground piece are further disposed with at least an inserting edge, respectively, which may be embeddingly engaged on the two sides of the tongue.

12. The electrical connector as defined in claim 1, wherein the upper and lower walls of the housing are formed to have a second opening, respectively, from which a ground finger is formed by bending inward.

13. The electrical connector as defined in claim 1, wherein the base body is disposed with a step on two sides of the tongue, respectively, and each step is formed to have a chamfer to provide guiding and restricting functions.

14. The electrical connector as defined in claim 13, wherein both sides of the lower wall of the housing are disposed with a restricting piece, respectively, to restrict and locate the step.

15. The electrical connector as defined in claim 13, wherein the inner of the step extends outward to form a protruding portion to provide restricting function as an USB plug being inserted.

16. The electrical connector as defined in claim 12, wherein the first terminal slots may be formed on top surface of the tongue and the second terminal slots may be formed on bottom surface of the tongue.

17. The electrical connector as defined in claim 1, wherein the legs of the first terminal assembly are alternately arranged in a front/rear fashion.
