Abstract

An electrical connector for mating with a mating connector includes an insulating body having a base and a tongue extending forward from the base. An upper row of terminals and a lower row of terminals are disposed in the insulating body. Each upper or lower row terminal has a contact portion exposed from an upper or a lower surface of the tongue, respectively. An upper and a lower grounding sheets are laminated to the upper and lower surfaces of the tongue respectively, and are assembled and connected to each other. A shielding case covers the periphery of the insulating body, and the upper and lower grounding sheets. The shielding case, the insulating body, and the upper and lower grounding sheets together form an insertion space for the mating connector to be inserted therein. The shielding case is respectively and electrically conducted to the upper and lower grounding sheets.

Claims

1. An electrical connector for mating with a mating connector, comprising:

an insulating body, having a base and a tongue extending forward from the base;

an upper row of terminals and a lower row of terminals disposed in the insulating body, 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;

an upper grounding sheet and a lower grounding sheet, laminated to the upper surface and the lower surface of the tongue respectively, wherein the upper grounding sheet and the lower grounding sheet are assembled and connected to each other; and

a shielding case, covering the periphery of the insulating body, the upper grounding sheet and the lower grounding sheet, wherein the shielding case, the insulating body, the upper grounding sheet and the lower grounding sheet together form an insertion space for the mating connector to be inserted therein, and the shielding case is respectively and electrically conducted to the upper grounding sheet and the lower grounding sheet.

2. The electrical connector of claim 1, wherein the upper grounding sheet and the lower grounding sheet are in a snap-fit connection to each other.

3. The electrical connector of claim 1, wherein the upper grounding sheet comprises a flat portion covering a rear segment of the upper surface of the tongue, and an elastic arm extending backward from the flat portion, and the elastic arm is located above the base and urges against the shielding case upward elastically.

4. The electrical connector of claim 3, wherein a plurality of depressed portions are depressed downward from the flat portion and used for snap-fitting a grounding elastic sheet in the mating connector.

5. The electrical connector of claim 3, wherein a snap-fit portion bends downward from each of two ends of the flat portion and covers a side edge of the tongue, and a protruding block protrudes from the snap-fit portion outward.

6. The electrical connector of claim 1, wherein the lower grounding sheet comprises a plate shaped portion covering a rear segment of a lower side of the tongue, and an urging portion extending backward from the plate shaped portion, and the urging portion is located below the base and urges against the shielding case.

7. The electrical connector of claim 6, wherein a plurality of depressed portions are depressed upward from the plate shaped portion and used for snap-fitting a grounding elastic sheet in the mating connector.

8. The electrical connector of claim 6, wherein a buckling portion bends upward from each of two ends of the plate shaped portion and covers a side edge of the tongue, and the buckling portion is provided with a through-hole.

9. The electrical connector of claim 1, wherein the insulating body comprises an upper body and a lower body, the upper body and the lower body together form the tongue, the upper row of terminals is fixed to an insulating block, the insulating block and the upper row of terminals are together insert-molded into the upper body, the lower row of terminals is fixed to the lower body, the lower body and the lower row of terminals are together assembled on a lower surface of the upper body, the upper grounding sheet is laminated to an upper surface of the upper body, and the lower grounding sheet is laminated to a lower surface of the lower body.

10. The electrical connector of claim 1, wherein the shielding case and the lower grounding sheet are connected by spot welding.
