PURPOSE: To simplifying and improving a shielding effect in relation to an electron device where the shield structure of a printed board unit to be plug-in connected through a shelf back board and the external wire connectors connected to said printed board unit is improved.
CONSTITUTION: A wavelike or U-shaped shield spring plate 24 is provided on the interior sides of the neighboring intervals of the line wire connector insertion holes 23 of a shield cover 21 covering a back board while having an insertion holes of the line wire connectors 22 to be plug-in connected from the rear side to a back board 3 of a shelf 20 for coming in contact with the sides of the line wire connectors 22 to be plugged into the shield spring boards so as to conduction-connect the conductive surfaces of the line wire connector sides to the shield cover 21.
