Abstract

An electrical connector used for mating a mating connector includes an insulation body having a base portion and a tongue extending from the base portion, terminals fixedly disposed in the base portion and grouped into an upper row and a lower row, and a middle shielding sheet embedded in the tongue and located between the upper and lower rows. The tongue has upper and lower surfaces arranged opposite to each other, and a front surface connected to the upper and lower surfaces. The upper and lower rows of terminals are exposed on the upper and lower, respectively. The middle shielding sheet has a front end surface extending out of the front surface, a slot formed on the front end surface, and a first projection portion extending into the slot, overlapping a central line of the middle shielding sheet along a longitudinal direction, and located behind the front surface.

First claim

What is claimed is:

1. An electrical connector for mating a mating connector, comprising:
an insulation body, having
a base portion; and
a tongue extending from the base portion and having
an upper surface;
a lower surface arranged opposite to the upper surface; and
a front surface connected to the upper surface and the lower surface;

a plurality of terminals, fixedly disposed in the base portion and grouped into an upper row of terminals and a lower row of terminals, wherein the upper row of terminals are exposed on the upper surface, the lower row of terminals are exposed on the lower surface, and wherein each of the terminals has a connecting portion, and the connecting portion is embedded in the base portion;
a middle shielding sheet, embedded in the tongue, located between the upper row of terminals and the lower row of terminals, and having
a front end surface, extending out of the front surface;
a slot, formed on the front end surface;
a first projection portion, extending into the slot, overlapping a central line of the middle shielding sheet along a longitudinal direction, and located behind the front surface; and

a metal casing wrapping the insulation body, comprising
a shielding casing; and
a wrapping casing, wrapping the base portion and the tongue, wherein the shielding casing is arranged outside of the wrapping casing;
wherein the wrapping casing has a first rear wall, the shielding casing has a second rear wall, the first rear wall and the second rear wall cover the base portion, and projections of the first rear wall, the second rear wall and connecting portions of the terminals in the longitudinal direction overlap each other;
wherein each of two sides of the shielding casing has a second soldering pin, the two second soldering pins are located on two sides of the insulation body, a fixing pin extends from the second rear wall, and the fixing pin is located between the two second soldering pins.

2. The electrical connector according to claim 1 , wherein the terminals include a pair of signal terminals in compliance with USB 2.0 specifications and arranged to vertically correspond to the first projection portion.

3. The electrical connector according to claim 2 , wherein the middle shielding sheet has a first hole located behind the first projection portion, overlapping the central line of the middle shielding sheet along the longitudinal direction, and arranged to vertically correspond to the pair of signal terminals.

4. The electrical connector according to claim 2 , wherein the middle shielding sheet has two second holes located behind the first projection portion and on two sides of the central line of the middle shielding sheet along the longitudinal direction, and arranged to one-to-one vertically correspond to the pair of signal terminals.

5. The electrical connector according to claim 1 , wherein the middle shielding sheet has a third hole located between the slot and a side edge of the middle shielding sheet, the terminals include a grounding terminal, and the third hole is arranged to vertically correspond to the grounding terminal.

6. The electrical connector according to claim 1 , wherein the slot defines a first space located on one side of the first projection portion, the terminals include a power supply terminal, and the power supply terminal is arranged to vertically correspond to the first space.

7. The electrical connector according to claim 1 , wherein each of the upper and lower rows of the terminals include at least one pair of differential signal terminals, each differential signal terminal has a first portion and a second portion extending from the first portion, the first portion and the second portion are arranged on the tongue, and a width of the first portion is larger than a width of the second portion.

8. The electrical connector according to claim 7 , wherein a distance between two neighboring first portions of the differential signal terminals is larger than a distance between two neighboring second portions of the differential signal terminals.

9. The electrical connector according to claim 7 , wherein each row of the upper and lower rows of the terminals include two non-high-speed terminals arranged on two sides of the pair of differential signal terminals, and a distance between the first portion and the neighboring non-high-speed terminal is less than the distance between the second portion and the neighboring non-high-speed terminal.

10. The electrical connector according to claim 1 , wherein each of the terminals has a soldering portion extending out of the base portion, soldering portions of the upper row of terminals are arranged in a row, and the soldering portions of the lower row of terminals are arranged in two rows.

11. The electrical connector according to claim 1 , wherein the middle shielding sheet extends and bends to form a pin, the pin extends out of the base portion, each of the terminals has a soldering portion extending out of the base portion, and soldering portions of the lower row of terminals and the pin are located on the same straight line.

12. The electrical connector according to claim 1 , wherein each of two sides of the wrapping casing has a first soldering pin, first soldering pins and second soldering pins are staggered in the longitudinal direction, the first soldering pins are closer to the base portion than the second soldering pins are, and the second soldering pins are closer to the tongue than the first soldering pins are.
