Low profile modular jack having spring-biased cover

An electrical connector comprising:

• an insulative base defining a mounting face thereof for mounting to a printed circuit board;
• terminals secured in said insulative base and each having a contacting section projecting upwards thereof;
• a detachable cover pivotally assembled on the insulative base and rotated to an opened position where a mating cavity is defined for receiving a mating plug therein and a closed position where the mating cavity is not large enough for receiving said mating plug;
• and
• at least one resilient tang located under said cover for providing a supporting force no matter the cover is in the opened position or in the closed position;
• wherein the contacting sections of the terminals project upward for supporting the mating plug not to contact with the insulative base;
• wherein the cover forms a concave configuration comprising a first stopping face parallel to the printed circuit board and a second stopping face perpendicular to the printed circuit board for respectively engaging with the mating plug;
• wherein the cover respectively forms a front skirt and a rear skirt, the front skirt covers a front end of the base when the cover is in a closed position, while the rear skirt covers a rear end of the base when the cover is in an opened position;
• wherein the rear skirt defines a first and a second engaging faces separately defined and the first engaging face is closer to a rear end of the rear skirt, the resilient tang abut against the first engaging faces when the cover is in the opened position while the resilient tang abut against the second engaging faces when the cover is in the closed position.
