The present invention relates to an FBT focus unit output terminal component connecting device capable of realizing high quality television.

In a conventional FBT focus unit board connection structure, as shown in FIGS. 1 and 2, the circular focus and the screen resistor patterns 20 and 30 that are printed on the upper side of the substrate 10 are focused on one side. And screen voltage output units 40 and 50, respectively, and the focus and screen resistor patterns 20 and 30 are in contact with the slider 70 provided in the focus unit 60.

In the conventional focus unit substrate having the connection connection structure as described above, as shown in the cross-sectional view of FIG. 2, the focus and screen resistor patterns 20 and 30 formed above the substrate 10 are formed inside the focus unit 60.

Accordingly, when the image quality is improved by superimposing an AC voltage parabola pulse voltage on the focus output unit 40 which is a DC voltage in order to realize high image quality, the television may be affected by noise generated by complex voltages. There was a lot of problems, such as not being able to realize the high picture quality properly.
