Electrical connector with improved buckling tab

An electrical connector adapted for electrically connecting with a mating plug, comprising:

• an insulating housing defining a recess, a receiving plate extending frontwardly from a rear surface of the recess and spaced apart from a bottom surface thereof;
• a plurality of terminals received in the receiving plate;
• and
• a shell coupled with the insulating housing to form an insertion space where the receiving plate is located for allowing the mating plug to insert therein and receive the receiving plate, the shell having a connecting plate located between the receiving plate and the bottom surface of the recess, a portion of the connecting plate being extended and curved upwards and then curved downwards and upwards sequentially to form a substantial split ring-shaped resilient element, the resilient element comprising an upper resistive portion extended from the connecting plate and located adjacent to the receiving plate and a lower resistive portion opposite to the upper resistive portion and located adjacent to the bottom surface of the recess, a free end of the lower resistive portion extending obliquely upwardly to form a connecting portion, a distal end of the connecting portion forming a propping portion located above the connecting plate,
• wherein when the mating plug is inserted, one of the upper resistive portion and the propping portion resist the mating plug firstly to make the other thereof uplift under the lower resistive portion resisting the bottom surface of the recess, and then the other thereof begins to resist the mating plug due to a reaction to the one thereof.
