PURPOSE: A matrix board for an automatic MDF(Main Distribution Frame) is provided to insert a metal connection pin having a metal spring into holes, and to connect one side with the other side, thereby maintaining a stable connection state. CONSTITUTION: Many board bodies(32) form many lines inputting subscriber lines(40), and form many holes passing through X-axis and Y-axis lines at certain intervals. A conductor(50) is installed on one side of the boards corresponding to the X-axis lines of the board bodies(32) and an inner side of the holes, and electrically connects the X-axis lines with the holes. A metal connection pin(51) inserted into the X-axis lines connects the X-axis lines. A metal spring(52) inserted into the metal connection pin(51) electrically connects the Y-axis lines with the conductor(50) separated when the metal connection pin(51) is inserted into the holes.
