<p>The present invention relate to an ordinary power supply for a digital door lock. According to the present invention, there is provided a digital door lock system having a mortise unit, an input unit, a control unit and a secondary battery unit, which includes a deadbolt insulating member including an insulating material surrounding a deadbolt of the mortise unit; (+)/(-) sliding contact surfaces of a positive conductor provided on at least one side surface of the deadbolt insulating member; a support plate unit embedded at a corresponding position of the mortise unit in a door frames and a building wall and provided with (+)/(-) DC power feeding wires introduced thereinto; a first elastic contact point connected to the (+)/(-) DC power feeding wires to make elastic contact with the sliding contact surfaces; and a second elastic contact point installed to the mortise unit and connected to the (+)/(-) DC power feeding wires to make elastic contact with the sliding contact surfaces. Thus, the external ordinary power is supplied to the second battery through the sliding contact point formed on the deadbolt, the mortise and the support plate unit in state that the door lock is locked, so that there is no need to exchange the battery of the digital door lock system, thereby reducing labor and maintenance costs.</p> |
