Electrical connector with improved metallic shell

An electrical connector comprising:

• an insulative housing defining a central receiving slot through a front face and extending along a longitudinal direction thereof with top and bottom longitudinal walls by two sides of the central receiving slot;
• two rows of contact receiving passages formed in the housing and located by the two sides of the central receiving slot and at least partially enclosed by the corresponding longitudinal wall, respectively;
• at least one passageway extending through a base of the housing in a mating direction which is perpendicular to the longitudinal direction;
• two rows of discrete and independent contacts disposed in the two rows of contact receiving passages, respectively;
• a pair of slots respectively located at lengthwise ends of the housing and extending through the top wall of the housing in communication with the central receiving slot and communicatively aligned with the passageway;
• and
• a metallic shell being in a hollow rectangle having a top plate for shielding the top wall of the housing and a bottom plate for shielding the bottom wall of the housing, a pair of securing portions retained in the lengthwise ends of the housing;
• wherein each securing portion includes:
• a connection portion unitarily projecting downward from a rear edge of the top plate, through the corresponding slot and abutting against the front face of the housing in the mating direction,
• a retaining portion extending rearward from the connection portion and forming a curved portion for firmly engaging with the at least one passageway with regard to the housing without relative movement, wherein the retaining portion is fully surrounded by said passageway only, and
• a solder tail extending from the retaining portion and extending out of a rear face of the housing.

• a metallic shell having a top plate for shielding the top wall of the housing and a bottom plate for shielding the bottom wall of the housing, a pair of securing portions retaining in the lengthwise ends of the housing;
• wherein the metallic shell being in a hollow rectangle configuration enclosing said housing under a condition that one of the two rows of contacts are electrically and mechanically engaged with the shell while the other not;
• wherein the housing further defines therein a plurality of receiving channels in one of the longitudinal walls intermingled with said one of the two rows of contact receiving passages along the longitudinal direction, and the shell further defines a plurality of retaining tangs rearwardly extending into the corresponding receiving channels, respectively;
• and
• wherein each securing portion includes:
