The present invention relates to a rail-type connection device having an embedded wire for a door, in which one end of a link bar is rotatably connected by a bracket installed in a door and the other end of the link bar is connected to be moved by sliding on a rail installed in a door frame. As a first wire installed inside the link bar, one end of the first wire is electrically connected to an electrical device installed in the door by a first slip ring installed in a connected portion of the link bar and the bracket. A terminal accommodated in the rail and rotated is installed in the other end of the link bar and electrically connected to the other end of the first wire. A second wire connected to external main power supply is installed inside the rail. The terminal comes into electrical contact with the second wire and can be moved when the link bar is operated. Therefore, the connection device enables the main power supply and the electrical device to be electrically connected without external exposure of the wires. |
