Electric connector and assembly thereof with better shielding effect and better appearance

An electrical connector, comprising:

• an insulating body, the insulating body comprising a tongue plate;
• a plurality of conductive terminals, each conductive terminal comprising a mating portion exposed to the tongue plate;
• a metal shielding shell, the metal shielding shell at least partially enclosing the tongue plate, the metal shielding shell defining a receiving space to receive a mating connector, the tongue plate being at least partially located in the receiving space;
• and
• a metal fixed shell, the metal fixed shell being connected to the metal shielding shell, the metal fixed shell extends forwardly and expands outwardly with respect to the metal shielding shell;
• wherein the metal shielding shell comprises a first wall portion, a second wall portion opposite to the first wall portion, a third wall portion connecting one side of the first wall portion and one side of the second wall portion, and a fourth wall portion connecting another side of the first wall portion and another side of the second wall portion;
• the receiving space is jointly enclosed by the first wall portion, the second wall portion, the third wall portion, and the fourth wall portion;
• and
• wherein the metal fixed shell comprises an outer wall;
• the outer wall is located on a same side as at least one wall portion of the first wall portion, the second wall portion, the third wall portion and the fourth wall portion;
• the outer wall protrudes beyond the at least one wall portion in a direction away from the receiving space;
• and the outer wall is parallel to the at least one wall portion which is located on the same side as the outer wall.
