As the unit mounting case 4, the both ends of the flat plate are bent in the same direction to form a cross section in a substantially U shape, and the height is higher than the openings 7 and 9 and wider than both ends of the mounting positions of the openings 7 and 9. The width is set so that the opening side of the mounting case 4 faces the rear panel 2, and the mounting case 4 is mounted on the bottom plate 3 of the cabinet 1 in a direction substantially perpendicular to the rear panel 2. A plurality of openings 5 and 6 are arranged in two rows on the mounting case 4 along the insertion direction of the units 8 and 10.

FIGS. 2A and 2B are partially enlarged views of the unit mounting structure of the electric device of the present invention. As the mounting case 4, a sheet metal is used in order to give a shielding effect to the units 8 and 10, and the openings 5 and 6 are formed in a substantially U-shape on the upper surface of the mounting case 4, respectively. Notches are provided, and bent pieces 11 and 15 are formed by bending downward so that the tips of the notches project toward the insertion side of the units 8 and 10. FIG. 2 (A) is an enlarged view of the opening 6 portion, and the bent piece 15 is formed in a substantially rectangular shape, and the longitudinal direction of the rectangle is parallel to the insertion direction of the unit 10, and is shown in FIG. As described above, the bent pieces 15 are arranged at two locations along the insertion direction of the unit 10. FIG. 2 (B) is an enlarged view of the opening 5 portion, and similarly to the above, the bending piece 11 is formed in a substantially rectangular shape, and the longitudinal direction of the rectangle is parallel to the insertion direction of the unit 8. Thus, as shown in FIG. 1, the bending pieces 11 are arranged at two positions along the insertion direction of the unit 8.

FIG. 3 is a vertical cross-sectional view showing a state in which a unit is attached to the unit attachment structure of the electric device of the present invention. The distance between the side wall portion 17 of the mounting case 4 and the bending piece 11 should be approximately the width of the unit 8, and both side surfaces of the inserted unit 8 should be sandwiched between the side wall portion 17 and the bending piece 11. Similarly, the distance between the side wall portion 18 of the mounting case 4 and the bent piece 15 is set to be approximately the lateral width of the unit 10, and both side surfaces of the inserted unit 10 are folded to the side wall portion 18. It is arranged to be clamped and fixed by the music piece 15.

As shown in FIGS. 2A and 2B, the bent pieces 11 and 15 of the openings 5 and 6 provided on the rear panel 2 side are the upper surface of the mounting case 4 and the bent pieces 11 and 15, respectively. The connecting portions 13 and 14 of 15 are deeply cut in the insertion direction of the unit to form the bent pieces 11 and 15, and the tips of the bent pieces 11 and 15 are inserted into the insertion openings 9 and 7. Each unit is guided by inserting each unit 10 and 8 when the units 10 and 8 are inserted into the units 12 and 16 respectively. I try to make it easier. When the unit is a descrambler module, etc., the inserted descrambler module is electrically connected to the electric circuit housed in the cabinet 1 side on the back side of each descrambler module, and the scramble method is used. Enable to receive different satellite signals. If necessary, a recess protruding downward may be provided on the upper surface of the mounting case 4, and the upper surfaces of the cases of the units 8 and 10 inserted in the recess may be pressed to suppress the vertical movement. good. Therefore, according to the present embodiment, it is possible to integrate the mounting cases of a plurality of units, and it is possible to reduce the number of parts and the number of man-hours for mounting the mounting case.

FIG. 4 is an explanatory view showing another embodiment of the unit mounting structure of the electric device of the present invention, and is a sectional view showing a mounted state of the unit. A metal plate 24 for mounting components, which is formed in a substantially U-shaped cross section, is provided on the upper plate 21 of the cabinet 1, and an upper side of the metal plate 24 is used for mounting, for example, a substrate 25. And bending pieces 23, 27, 29, and 31 are provided in the same manner as in the above-described embodiment, and the distance between the bending pieces 23 and 27 is set to be substantially the width of the unit 10. , Both sides of the unit 10 are clamped and fixed by the bending pieces 23 and 27, and similarly, the distance between the bending pieces 29 and 31 is approximately the width of the unit 8. The both sides of the unit 8 are clamped and fixed by the bent pieces 29 and 31.

In the bending piece 23 and the bending piece 27, the curved portions 22 and 26 are arranged so as to face outward with respect to the insertion opening of the unit 10 in the same manner as in the above embodiment, and the unit 10 is inserted. The bending piece 29 and the bending piece 31 are provided with curved portions 28 and 30 in the same manner as in the above-described embodiment so that the bending pieces 28 and 30 are directed outward with respect to the insertion opening of the unit 8. They are arranged so that the unit 8 can be guided and easily inserted.
