PURPOSE:To facilitate a work to mount and demount a source cord and to reduce the number of parts used by a method wherein a source terminal board is covered with a removable small second cover, and the source cord connected thereto is secured by means of a securing part formed to a part of the source cord. CONSTITUTION:A work to connect a source cord 2 to a source terminal board 4 is effected by removing a second cover 7 by pulling off a securing screw 8. In this case, the source terminal board 4 is visually watched from the outside as it is, and with this state, the core of the source cord 2 is inserted in the source terminal board 4. The peripheral edge of an opening window formed in the first cover 6 is nipped between lower and upper ribs 7c and 7b formed on the peripheral edge part of the top wall of the second cover 7 to close the opening window with the second cover 7. The source cord 2 is pressed by means of a securing part 7a and a securing screw 8 is fastened against the bottom plate of an electric device containing box A. This operation brings the electric device containing box A into a state to be closed with a large first cover 6 and the smaller second cover 7. |
