Electrical connector and electrical connector assembly

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.
