Flippable electrical connector

A flappable receptacle connector adapted for mating with a plug connector either in an upside direction or in an upside-down direction which defines a mating slot and a pair of metallic latches with hooks protruding into the mating slot, the receptacle connector comprising:

• an insulating housing comprising a base and a mating tongue extending from the base, the mating tongue intending to insert in the mating slot of the plug connector;
• a row of first contacts and a row of second contacts, the contacts comprising plate contacting sections exposed upon opposite surfaces of the mating tongue and leg section extending from the base;
• a shielding plate disposed in the mating tongue and the base and isolated from the first and second contacts;
• and
• wherein the mating tongue defines two opposite lateral sides and a front side connecting with front ends of the two lateral sides thereof, the shielding plate defines corresponding lateral sides and corresponding front side thereof, the lateral sides of the shielding plates slightly protruding beyond the corresponding lateral sides of the mating tongue in a transverse direction for protection under an improper angular mating of the plug connector;
• wherein each lateral side of the shielding plate define an inflexible locking notch for locking with the hooks of the plug connector;
• wherein the lateral sides of shielding plate slightly protrude beyond the mating tongue, and each of the lateral sides of the mating tongue forms a through notch which is generally matching with the inflexible locking notch of each of the lateral sides of the shielding plate;
• wherein the inflexible locking notch slightly protrude beyond the corresponding through notches in the transverse direction.
