Claim 12:
13. An electrical connector, comprising:
an insulating body having a base portion, and an extension portion extended rearward from a rear end of the base portion, the extension portion extending upward or downward to form at least one positioning portion, the at least one positioning portion having a front clamping section and a rear clamping section, the front clamping section and the rear clamping section being longitudinally separated from each other to form a clamping groove between the front clamping section and the rear clamping section;
a plurality of terminals fastened in the base portion of the insulating body;
an elastic element mounted to a bottom surface of the insulating body, the elastic element having a body portion, at least one elastic arm slantwise extended frontward from one end of the body portion, at least one extension arm extended laterally from at least one side of the body portion, and a tail portion slantwise extended upward and rearward from the other end of the body portion, the at least one elastic arm being slightly inclined upward, a front end of the at least one elastic arm being bent downward to form a snap hook;
a camshaft having a rotating shaft and a cam portion, the cam portion being arranged corresponding to the tail portion of the elastic element, the rotating shaft being accommodated in the clamping groove of the at least one positioning portion; and
a shell surrounding the insulating body, the plurality of the terminals and the elastic element, a bottom of the shell having a through hole vertically penetrating through the bottom of the shell, the through hole being corresponding to the snap hook;
wherein when the rotating shaft rotates in a forward direction, the rotating shaft drives the cam portion to rotate, the cam portion pushes the tail portion to twist the at least one extension arm, the at least one extension arm drives the at least one elastic arm to twist downward, the snap hook passes through the through hole; and
wherein when the rotating shaft rotates in a reverse direction, the cam portion gradually breaks away from the tail portion to make the at least one extension arm elastically return to an original position, the at least one extension arm drives the at least one elastic arm to move to an initial position, the snap hook is receded from the through hole.
