Disclosed is a power supply connection structure device for electrically connecting an electrical appliance to a power source. The connections structure device is comprised of: a first electric connection unit; a second electric connection unit; and a control unit which shifts between an idle state and an activation state, wherein in the idle state, the first and second electric connection units are not electrically connected to the power source, and that in the activation state, the control unit electrically connects the first and second electric connection units to the power source, so as to electrically connect an electric circuit between the power supply connection structure device, the power source and the electrical appliance, thereby providing a power supply to the electrical appliance. The power supply connection structure device further comprises a ground wire connection unit which has a ground wire plughole. The control unit is coupled with the ground wire connection unit in such a manner that the control unit is activated by a ground pin which is inserted into the ground wire plughole. The control unit comprises two micro-switches, a push member, two actuation members and a reposition arrangement. Each of the actuation members comprises an actuation arm and a drive arm which is extended from the actuation arm. Each actuation arm is driven by the push member and the reposition arrangement to reciprocate. Each of the micro-switches comprises a resilient element and an electric connection element which is an electric conductive element. When the ground pin is inserted into the ground wire plughole, the push member is driven to move by the ground pin, the actuation arm is pressed by the push member to drive the drive arm to bias against the resilient element, thus the resilient element forces the electric connection element to move, so as to allow the power supply connection structure device to be electrically connected to the power source. |
