にしている。 FIG. 1 is a sectional view showing an embodiment of the present invention. The case 11 has a structure in which the tapped holes used to fix the inner case 5 and the printed circuit board 6 with the fixing screws 7 have been removed, compared to the conventional case 1 shown in FIG. The case 11 is attached to the case 11 in the case 11, and the case 11 is paired with the case 11 to form an outer case.
A shielding partition wall 11a that prevents mutual electrical interference between circuit blocks constituting the high frequency device.
The shielding partition wall 12a is formed in correspondence with the partition wall 11a, and the waterproof flange part 12b is formed in correspondence with the waterproof flange part 11b integrated with the partition wall 11a. Therefore, the printed circuit board 15 of FIG.
is sandwiched between the case 11 and a cover 12 that has a shield partition wall 12a between each circuit and a waterproof flange portion 12b, and is pressed against the end surfaces of the partition walls of both the case and the cover by tightening the cover fixing screws 14. are used to configure each circuit block.
At this time, by providing a clearance between the waterproof flanges 11b and 12b to the extent that the waterproof performance of the gasket 13 is not impaired, the printed circuit board 15 and the bulkhead that abuts the printed circuit board 15 of both the case 11 and the cover 12 can be separated. Ensures pressure welding.
