Claim 13:
14. An electrical connector cooperated with a docking connector, the docking connector including an outer shell, two sides of a bottom wall of the outer shell defining two openings, the electrical connector comprising:
an insulating body;
a plurality of terminals fastened in the insulating body;
an elastic element mounted to a surface of the insulating body, the elastic element having a body portion, two elastic arms slantwise extended frontward and outward, and then extended frontward from two sides of one end of the body portion, two extension arms slantwise extended outward and rearward from two front ends of two sides of the body portion, and a tail portion slantwise extended upward and rearward from the other end of the body portion, the two elastic arms being slightly inclined upward, a front end of each elastic arm being bent downward to form a snap hook;
a camshaft arranged at a rear end of the insulating body, the camshaft having a rotating shaft and a cam portion, a front of the cam portion being outwardly arched along a radial direction of the rotating shaft to form a cam surface, the cam portion being arranged corresponding to the tail portion of the elastic element; and
a shell surrounding the insulating body, the plurality of the terminals, the elastic element and the camshaft, a bottom of the shell having two through holes vertically penetrating through the bottom of the shell, the two through holes being corresponding to the two snap hooks;
wherein when the rotating shaft rotates in a forward direction, the rotating shaft drives the cam portion to rotate, the cam surface of the cam portion slides frontward and upward to a tip of the tail portion along a rear surface of the tail portion, the cam surface of the cam portion pushes the tail portion to twist the two extension arms, the two extension arms drive the two elastic arms to twist downward to abut against an inner surface of the shell, the two snap hooks are buckled to the two through holes, the two snap hooks project out of the shell through the two through holes, and the two snap hooks are buckled to the two openings of the docking connector, the electrical connector is locked to the docking connector; and
wherein when the rotating shaft rotates in a reverse direction, the rotating shaft drives the cam surface of the cam portion to rotate to slide downward from the tip of the tail portion, the cam surface of the cam portion gradually breaks away from the tip of the tail portion to make the two extension arms elastically return to two original positions, the two extension arms drive the two elastic arms to move to two initial positions, the two snap hooks are receded from the two openings and the two through holes, so the electrical connector is unlocked with the docking connector.
