Electrical connector for reliably mounted on a printed circuit board

Abstract

An electrical connector (100) includes an insulative housing (1) defining a number of passageways (121) for receiving corresponding contacts (2), and a metal shield (3) enclosing the insulative housing (1). The metal shield has a top face (31), a bottom face (32) and a pair of side faces (33). The bottom face includes a pair of first board mounting legs (325) downwardly and a slot (326) between the first board mounting legs (325). The first board mounting legs (325) are disposed in communication of the slot (326) and mounted on a printed circuit board (4). The length of the slot (326) is equal to the total length of the first board mounting legs (325). With the addition of the first board mounting legs (325), the connector (100) can be more stably mounted on the printed circuit board.

2. The electrical connector according to claim 1, wherein the first board mounting legs respectively include a major surface disposed face to face.

3. The electrical connector according to claim 1, wherein the metal shield includes a top face opposite to the bottom face, a pair of side faces connecting the top and bottom faces, and a receiving space between the side faces.

4. The electrical connector according to claim 3, wherein the top face include a pair of first fingers and a pair of second fingers, the first and second fingers extending into the receiving space wherein the first fingers extend in a direction opposite to that of the second fingers.

5. The electrical connector according to claim 3, wherein the bottom face includes a pair of third fingers facing to the second fingers, said first board mounting legs disposed between the third fingers.

6. The electrical connector according to claim 3, wherein the metal shield includes a rear face perpendicular to the front face, the rear face defining a pair of second board mounting legs, each first board mounting leg having a major surface perpendicular to a major surface of each second board mounting leg.

7. The electrical connector according to claim 6, wherein the second board mounting legs are coplanar with the rear face.

8. The electrical connector according to claim 1, wherein the bottom face includes a middle projection portion with the first board mounting legs disposed therein.

9. The electrical connector according to claim 1, wherein the insulative housing includes a base and a tongue plate extending from the base with the passageways defined therein.

10. The electrical connector according to claim 1, wherein each passageway extend along a longitude direction of the insulative housing, the contacts include engaging portions received in the passageways wherein the engaging portions are disposed in a row along a direction perpendicular to the longitude direction of the insulative housing.

11. The electrical connector according to claim 10, wherein the contacts include soldering portions parallel to the engaging portions and extending beyond the insulative housing.

12. The electrical connector according to claim 1, wherein the insulative housing includes a bottom plate for mating with the bottom face, the first board mounting legs disposed on lateral sides of the bottom plate.

13. An electrical connector assembly comprising: an insulative housing defining a base with a mating tongue and a bottom plate essentially forwardly horizontally extending therefrom;a plurality of contacts disposed in the housing with corresponding contacting sections seated upon the mating tongue; anda unitary metallic shell enclosing the housing and including a shroud portion including opposite top and bottom faces and two side faces commonly defining a mating cavity receiving said mating tongue therein, said bottom face including a central region essentially seated upon the bottom plate, said shell further including a rear face covering a rear surface of the base.

14. The connector assembly as claimed in claim 13, wherein two lateral sides regions of the bottom face of the shell are downwardly offset from the central region and essentially coplanar with the bottom plate.

15. The connector assembly as claimed in claim 13, wherein a pair of mounting legs unitarily extend from the bottom face and located by two sides of the bottom plate.

16. The connector assembly as claimed in claim 13, wherein said contacts include corresponding horizontal mounting sections which do not extend beyond the rear face of the shell.

17. An electrical connector assembly comprising: an insulative housing defining a base with a mating tongue and a bottom plate essentially forwardly horizontally extending therefrom;a plurality of contacts disposed in the housing with corresponding contacting sections seated upon the mating tongue; and

18. The connector assembly as claimed in claim 17, wherein a pair of mounting legs unitarily extend from the bottom face and located by two sides of the bottom plate.
