By combining this again with the main frame 31 using the screw 36, the printed circuit board 35 is installed in a solid state above the main frame 31.

However, the printed circuit board 35 is simply coupled to the upper peripheral edge of the main frame 31 through the screw 36, so that the coupling of the printed circuit board 35 is cumbersome, and in particular, it is installed on the main frame 31. When the printed circuit board 35 is repaired and maintained, the screw 36 is disassembled one by one, and after repairing it, the workability and serviceability due to the recombination are remarkably deteriorated, as well as external impact. In this case, the impact force is transmitted to the printed circuit board as it is, there are many problems such as breakage of the printed circuit board.

The present invention has been made to solve the various problems as described above, the purpose of which is to separate the front and rear and left and right sides of the printed circuit board is installed in the inner side of the main frame of the printed circuit board is provided in the separate No need for fasteners, it is elastically easy and easy to fix and fix, easy to disassemble and combine printed boards, improves maintainability, and the printed circuit board coupled to the board coupler is firm to the main frame. The present invention provides a coupling device for a main frame of a television and a printed circuit board which can be fixed while being coupled to each other, thereby preventing damage to the printed circuit board due to an external impact.
