Abstract

An electrical connector for mating with a mating connector having a metal elastic sheet. The electrical connector includes an insulating body, a middle shielding sheet and a metal casing. The insulating body includes a base, a tongue extending forward from the base, and an upper row and a lower row of terminals. Each upper and lower row terminals has a contact portion exposed from upper and lower surfaces of the tongue respectively. The middle shielding sheet is disposed in the tongue and located between the upper row and lower row of terminals. The middle shielding sheet includes a groove exposed from a side of the tongue, for being buckled by the metal elastic sheet to stop forward displacement of the metal elastic sheet. The metal casing wraps a periphery of the insulation body to form a mating cavity, for the mating connector to be entered therein.

First claim

What is claimed is:

1. An electrical connector for mating with a mating connector, the mating connector having at least one metal elastic sheet, the electrical connector comprising:
an insulating body, having a base, a tongue extending forward from the base, and an upper row of terminals and a lower row of terminals, wherein each of the upper row of terminals has a contact portion exposed from an upper surface of the tongue, and each of the lower row of terminals has a contact portion exposed from a lower surface of the tongue;
a middle shielding sheet, disposed in the tongue, located between the upper row of terminals and the lower row of terminals, and comprising at least one groove exposed from a side of the tongue, and a notch disposed at each of two sides of the middle shielding, wherein the groove is used for being buckled by the metal elastic sheet to stop forward displacement of the metal elastic sheet;
an upper shielding sheet and a lower shielding sheet respectively laminated to the upper surface and the lower surface of the tongue, wherein the upper shielding sheet has two first bending portions disposed at two ends of the upper shielding sheet, the lower shielding sheet has two second bending portions disposed at two ends of the lower shielding sheet, and each of the first bending portions and the second bending portions enters into corresponding one of the notches; and
a metal casing, wrapping a periphery of the insulation body, wherein a mating cavity is formed in a peripheral space of the tongue by the metal casing, for the mating connector to be entered therein.

2. The electrical connector of claim 1 ,
wherein the tongue comprises a front surface and two side surfaces located between the upper surface and the lower surface;
wherein the middle shielding sheet comprises a plate portion fixed in the tongue and an extending portion extending out of one of the two side surfaces of the plate portion; and
wherein the groove is disposed at the extending portion and located outside the tongue, and the extending portion and the groove are both located in the mating cavity.

3. The electrical connector of claim 2 , wherein the extending portion is disposed at each of two sides of the plate portion, the two extending portions symmetrically extend out of the two side surfaces, and the corresponding two grooves are located outside the tongue.

4. The electrical connector of claim 1 ,
wherein the tongue comprises a snap-fit slot corresponding to the groove, and the groove has a buckling wall close to the front of the middle shielding sheet and exposed from the snap-fit slot; and
wherein the metal elastic sheet buckles to the buckling wall and partially locates in the snap-fit slot and the groove, and the buckling wall stops forward displacement of the metal elastic sheet.

5. The electrical connector of claim 4 , wherein an outline of an inner wall of the groove is the same as that of an inner wall of the snap-fit slot.

6. The electrical connector of claim 1 , wherein the groove has a buckling wall close to the front of the middle sheet, the buckling wall is arc-shaped, the metal elastic sheet buckles to the buckling wall, and the buckling wall stops forward displacement of the metal elastic sheet.

7. The electrical connector of claim 1 ,
wherein the tongue comprises a front surface and two side surfaces located between the upper surface and the lower surface; and
wherein the middle shielding sheet comprises a plate portion fixed in the tongue, and at least one protecting portion extends out of the front surface of the plate portion.

8. The electrical connector of claim 1 ,
wherein the upper shielding sheet and the lower shielding sheet are mounted and connected to each other by two snap-fit structures, and each of the notches reserves a space for the corresponding snap-fit structure.

9. The electrical connector of claim 1 , wherein the middle shielding sheet comprises a mounting portion disposed at a rear segment of the middle sheet and fixed in the base, and the width of the mounting portion is greater than the width of the tongue.

10. The electrical connector of claim 1 ,
wherein the tongue further comprises a front surface and two side surfaces located between the upper surface and the lower surface; and
wherein the middle shielding sheet has a plate portion fixed in the tongue, the groove is disposed at the plate portion and located in the tongue, and the groove does not exceed the side surfaces.
