Abstract

An electrical connector, for mating a mating connector having two metal elastic sheets, includes: an insulation body having a base portion and a tongue located at a front end thereof; an upper and lower rows of terminals fixed to the base portion, each terminal having a contact portion exposed from an upper or lower surface of the tongue; a middle shielding sheet, fixed to the base portion and tongue, and located between the two terminal rows; two snap-fit portions disposed at two sides of the middle shielding sheet and exposed from two sides of the tongue, where the two metal elastic sheets buckle the snap-fit portions to prevent disengagement; and an outer metal casing wrapping peripheries of the base portion and tongue. When the mating connector is inserted into the electrical connector after it's assembling, the two snap-fit portions are fixed to the mating connector to ensure stable high-frequency performance.

First claim

What is claimed is:

1. An electrical connector for mating with a mating connector, the mating connector having at least two metal elastic sheets, the electrical connector comprising:
an insulation body, having a base portion and a tongue located at a front end of the base portion;
a plurality of terminals fixedly disposed in the base portion in a manner of an upper row and a lower row, wherein each of the terminals has a contact portion exposed from an upper surface or a lower surface of the tongue, and the mating connector and the contact portions are contacted;
a middle shielding sheet, fixedly disposed at the base portion and the tongue, and located between the upper row of terminals and the lower row of terminals;
at least two snap-fit portions disposed at two sides of the middle shielding sheet and exposed from two sides of the tongue, wherein two of the metal elastic sheets buckle the snap-fit portions to stop the metal elastic sheet from being disengaged;
an outer metal casing, wrapping peripheries of the base portion and the tongue; and
an inner metal casing, wherein the inner metal casing comprises:
at least one covering portion disposed on an upper surface of the tongue; and
at least one extending portion extending from the covering portion toward the base portion, the extending portion having at least one contact arm, and the contact arm urging an inner wall of the outer metal casing.

2. The electrical connector according to claim 1 , wherein the extending portion includes two positioning portions, the base portion includes two positioning slots corresponding to the two positioning portions, and the two positioning slots accommodate and fix the two positioning portions.

3. The electrical connector according to claim 1 , wherein the upper row of terminals comprises two grounding terminals, two power supply terminals and two signal terminals, the lower row terminals comprises two grounding terminals, two power supply terminals and two signal terminals, and the upper row of terminals and the lower row of terminals are disposed symmetrically on the upper surface and the lower surface of the tongue respectively.

4. The electrical connector according to claim 1 , wherein the outer metal casing comprises a wrapping casing and a shielding casing, the wrapping casing wraps the peripheries of the base portion and the tongue, the shielding casing is disposed out of the wrapping casing, each of two sides of the wrapping casing has a first soldering pin, each of two sides of the shielding casing has a second soldering pin, the first soldering pins and the second soldering pins are staggered front and back, the first soldering pins are close to a lateral side of the base portion, and the second soldering pins are close to a lateral side of the tongue.

5. The electrical connector according to claim 4 , wherein the wrapping casing has a first rear wall, the shielding casing has a second rear wall, the first rear wall includes a first middle portion and first sheltering portions located at two sides of the first middle portion, the second rear wall includes a second middle portion and a second sheltering portion connected to a lower part of the second middle portion, the first middle portion and the second middle portion are approximately superposed front and back, the second rear wall forms a notch at a place corresponding to the first sheltering portion, and the second sheltering portion exceeds the first middle portion downward.

6. An electrical connector for mating with a mating connector, the mating connector having at least two metal elastic sheets, the electrical connector comprising:
an insulation body, having a base portion and a tongue located at a front end of the base portion;
a plurality of terminals fixedly disposed in the base portion in a manner of an upper row and a lower row, wherein each of the terminals has a contact portion exposed from an upper surface or a lower surface of the tongue, and the mating connector and the contact portions are contacted;
a middle shielding sheet, fixedly disposed at the base portion and the tongue, and located between the upper row of terminals and the lower row of terminals;
at least two snap-fit portions disposed at two sides of the middle shielding sheet and exposed from two sides of the tongue, wherein two of the metal elastic sheets buckle the snap-fit portions to stop the metal elastic sheet from being disengaged; and
an outer metal casing, wrapping peripheries of the base portion and the tongue;
wherein the middle shielding sheet has a plate portion fixedly disposed in the tongue, two protruding portions extend respectively from two sides of the plate portion out of the two sides of the tongue, two of the snap-fit portions are grooves disposed at the two protruding portions, and the two grooves are exposed from the two sides of the tongue.

7. The electrical connector according to claim 6 , further comprising an inner metal casing, wherein the inner metal casing comprises:
at least one covering portion disposed on an upper surface of the tongue; and
at least one extending portion extending from the covering portion toward the base portion, the extending portion having at least one contact arm, and the contact arm urging an inner wall of the outer metal casing.

8. The electrical connector according to claim 7 , wherein the extending portion includes two positioning portions, the base portion includes two positioning slots corresponding to the two positioning portions, and the two positioning slots accommodate and fix the two positioning portions.

9. The electrical connector according to claim 6 , wherein the upper row of terminals comprises two grounding terminals, two power supply terminals and two signal terminals, the lower row terminals comprises two grounding terminals, two power supply terminals and two signal terminals, and the upper row of terminals and the lower row of terminals are disposed symmetrically on the upper surface and the lower surface of the tongue respectively.

10. The electrical connector according to claim 6 , wherein the outer metal casing comprises a wrapping casing and a shielding casing, the wrapping casing wraps the peripheries of the base portion and the tongue, the shielding casing is disposed out of the wrapping casing, each of two sides of the wrapping casing has a first soldering pin, each of two sides of the shielding casing has a second soldering pin, the first soldering pins and the second soldering pins are staggered front and back, the first soldering pins are close to a lateral side of the base portion, and the second soldering pins are close to a lateral side of the tongue.

11. The electrical connector according to claim 10 , wherein the wrapping casing has a first rear wall, the shielding casing has a second rear wall, the first rear wall includes a first middle portion and first sheltering portions located at two sides of the first middle portion, the second rear wall includes a second middle portion and a second sheltering portion connected to a lower part of the second middle portion, the first middle portion and the second middle portion are approximately superposed front and back, the second rear wall forms a notch at a place corresponding to the first sheltering portion, and the second sheltering portion exceeds the first middle portion downward.
