STRUCTURE OF DRAWING RAIL FOR ELECTRONIC DEVICE

PURPOSE: To provide a structure of a drawing rail of a drawable unit by which the reliability of power and signal feeding to the drawable unit which is mounted on an electrical device, can be increased and the mounting space of the drawable unit can be reduced. CONSTITUTION: Conductive plates 8, 10, 12, and 14 are so fitted in with an outside rail 14, an intermediate rail 4, and an inside rail 6 of a drawing rail 3 that they may be insulated from each other. Then, the conductive plates are connected and brought into contact with each other by means of a conductive plate 17 and firmly-set mouth-shaped elastic pieces 18, 19. One end of the conductive plate 14 is connected to a connector 20 of a connection cable from a unit 2 and one end of the conductive plate 10 is connected to a connector 21 of a connection cable from a main body of an electrical device. When the rail is drawn or it is in the middle of being put back or it is put back to the original position, the conductive plates which are fitted in with the drawing rail are always connected and brought into contact with each other and thereby the conduction between these conductive plates is maintained. Due to this structure of the rail, the feeding and the transmission of signals to the unit are possible and a cable mounting space can be eliminated.
