９をシヤーシ６に固定する。 As mentioned above, the bent portions 7a of the tongue pieces 7, 8,
The vertical distance A between the tip protrusions P 1 and P 2 of 8a, the gap B between the tongues 7 and 8 when viewed diagonally from above, and the thickness C of the printed circuit board 9 are determined by adjusting distances 1 and 2 to appropriate lengths. Since the configuration is such that the relationship A<C<B is established by selecting the printed circuit board 9 as shown in FIG.
from the end on the grounding copper foil pattern 13 side, with the copper foil pattern 13 facing down, insert it diagonally from above, and then push down the other end to attach the printed circuit board 9 as shown in the fourth figure. Seat hole 12 with chassis 6
The printed circuit board 9 is fixed to the chassis 6 by fitting into the fixing part 10 protruding from the bottom plate 6b of the board and twisting the claw part 11 at the tip.

され、アースも確実である。 If mounted in this way, the grounding copper foil pattern 13 of the printed circuit board 9 will be able to push the tongue piece 8 on the principle of leverage when the end surface of the printed circuit board 9 on the mounting hole 12 side is pushed down. Tongue piece 7 as a fulcrum
can be pushed up. At this time, since the vertical distance A between the tip protrusions P 1 and P 2 of the bent portions 7 a and 8 a of the tongues 7 and 8 is set in advance to be smaller than the thickness C of the printed circuit board 9, when attached, the The grounding copper foil pattern 13 of the board 9 is strongly pressed against the tongue piece 8, and the grounding is also reliable.
第６図は、本考案の他の実施例を示し、第２図

ナツプ止めされる。 In this embodiment, the tongue piece 14 is only cut and raised from the side plate 6a of the chassis 6 perpendicularly to the side plate 6a, so there is no elasticity, and the printed circuit board 9
As in the first embodiment, the cut-and-raised tongue piece 8 on the other side that holds the is provided with a bent part 8a to impart elasticity, and both tongue pieces 8 and 14 are arranged at different positions, and the fixed part 15 is It has a structure that can be fastened with a snap. Next, the method of mounting the printed circuit board 9 is the same as that of the first embodiment of the present invention shown in FIG. Just push it into the tip of No. 15 and it will snap into place.
