Modified socket

A modified socket for a plug having two pins to plug therein, comprising

• a casing;
• a rotatable cap, rotatably disposed on the casing in a manner that the rotatable cap is rotatable between an inserting position and a power-on position, the rotatable cap sequentially comprising a first travel and a second travel on a path rotating from the inserting position to the power-on position, the rotatable cap having a cap body and a pair of plug holes penetrating the cap body for the pins to insert therethrough, respectively;
• two pairs of electrical clips, each disposed in the casing and having a fixed jaw and a movable jaw electrically connected to the fixed jaw, each of the movable jaws being movable between a home position and an accumulating position, the two pairs of electrical clips being corresponding to the plug holes, respectively;
• and
• a resilient means for accumulating resilient force when the movable jaws are moved toward their corresponding accumulating positions, respectively, and for releasing the resilient force to move the movable jaws back to their corresponding home positions, respectively;
• wherein, when viewed from a direction facing the rotatable cap while the rotatable cap is located at the inserting position, the plug holes are not overlapped with contours of the two pairs of the electrical clips, respectively, in a manner that the two pairs of electrical clips are unable to electrically connect to the pins inserted in the plug holes, respectively;
• wherein, when the rotatable cap is rotated toward the power-on position and within the first travel, the rotatable cap is adapted to push the two movable jaws toward their corresponding accumulating positions, respectively, and make the resilient means to accumulate the resilient force;
• wherein, when the rotatable cap enters the second travel right from the first travel, the resilient means starts to release the resilient force to push the movable jaws back to their corresponding home positions, respectively, and further drive the rotatable cap to rotate to the power-on position;
• wherein, when the rotatable cap is located at the power-on position, the two pairs of electrical clips are adapted to contact and electrically connect to the two pins, respective.
