The present invention relates to a focus unit input terminal pin coupling device for easily and easily connecting and connecting the lead of the diode that is doped on the high voltage bobbin of the FBT and the input terminal pin protruding from the back of the focus unit. The upper side of the (2) is provided with a terminal coupler (6) is formed therein the elastic coupling piece 5 therein is elastically coupled and fixed to the input terminal (8) entered on the back of the focus unit (3), In front of the terminal coupler 6, the lead coupling piece 7 is integrated into the lead of the diode 4 mounted on the diode holder 2 and the terminal pin of the high-voltage bobbin 1 by soldering. The point is to be fixed.;Accordingly, the input terminal drawn out from the back of the focus unit of the FBT can be easily and easily connected to the lead of the diode, and there is no need to draw a separate lead from the back of the diode and the focus unit. It is possible to prevent the occurrence of defects caused by quench between adjacent parts due to drawing out.
