The present invention relates to an FBT focus unit lead wire coupling structure in which the focus and screen leads drawn out from the FBT focus unit can be fixed to be spaced apart from the FBT case by a predetermined distance. Lead wire engaging holes 5 are formed to protrude from the lead unit receiving grooves 4 and 4 'through the diaphragm 3 on one side of the focus unit 2 of the focus unit 2, and the lower side of the lead wire engaging hole 5 is provided. The notch groove 6 is recessed in the groove so that the focus and screen lead wires 7 and 8 drawn out from the focus unit 2 are spaced apart from the FBT case 1 so as to be tightly inserted into the lead wire coupler 5. .;Accordingly, the focus and screen lead wires drawn from the focus unit are prevented from sagging and flowing, and the lead wires are coupled and fixed in a rigid state, and in particular, the lead wires are installed at a certain distance from the FBT case to ensure a constant insulation distance. It will be easy, and thereby the electrical characteristics can be improved.
