Reference numeral 1 denotes a case, which comprises a main body 2 and a lid 3 made of a metal material (for example, die casting) as is well known.
Reference numeral 4 denotes a mounting leg portion. In the present application, the mounting leg portion 4 is integrally formed with the main body, and is arranged so as to be on a diagonal line of a bottom surface and a side surface which are mounting surfaces. The mounting leg 4 may be formed separately from the main body. Reference numeral 4a is a fastening screw for fastening the main body, which is held by the mounting leg portion 4 at the time of shipment from the manufacturer. Reference numeral 5 is a ground terminal, and 6 is a coaxial connector. Reference numeral 9 indicates a circuit board that constitutes an electronic circuit. Next, in the contact plug 6, 11 is a hollow cylindrical outer conductor that is formed integrally with the case 1 and projects to the outside, has an external thread 12 on the outer circumference, and has an opening toward the case inner surface 2a. . Reference numeral 13 is an insulator, which is a well-known insulator such as polyethylene, and is inserted from the opening of the outer conductor 11 so that the outer periphery of the insulator 13 is in contact with the inner surface of the outer conductor 11. Although the present application shows an example in which the tangent line 6 is formed on the side surface that opposes each other, the present invention is not limited to this and may be on any side surface. A jaw-shaped engagement piece 14 is provided on the inner end side of the insulator 13, the engagement 14 abuts on the inner surface 2a of the case, and both sides of the lower engagement piece 14 are rotated around the fixing member 8. It abuts against the stopper 8d to prevent the insulator 13 from rotating.

Next, the center conductor is bent by using a known plate-shaped conductive material, and 20 is a circuit connecting terminal of the circuit board. Next, the fixing member 8 of the substrate is formed integrally with the main body 2 or is formed by fixing a separate conductive member to the main body 2, and has a flat surface 8a for receiving the circuit board 9. The pedestal part 8b and the ground part 9b of the circuit board 9
The columnar connecting member 8c for connecting to is shown.

Next, the assembly of the above structure will be described. The circuit board 9 is placed on the pedestal portion 8b shown in FIG. 1 as shown in FIGS. In this case, the concave portion 9c of the circuit board 9 corresponds to the connecting portion 8c and the terminal 20, respectively. Next, the ground portion 9b and the connecting member 8c and the circuit portion 9a and the terminal 20 are connected to each other by soldering or other connecting means, and as a result, the circuit board 9 and the main body 2 are integrated. Further, next, the lid body 3 is fixed to the step 2b formed on the peripheral edge portion of the opening end of the main body 2 shown in FIG. 1 by press fitting or other fixing means. Needless to say, at this time, a fixing method considering the shield characteristics is necessary.

Next, a method of mounting the case 1 will be described. FIG. 4 is a perspective view showing an installed state when the side surface of the antenna joint reception device of the present application is a mounting surface. Case 1
Is attached to a predetermined position on the wall surface 25 or a mounting wall surface in the storage box, and the fixing screw 4a is screwed toward the wall to mount the wall surface 25. FIG. 5 is a perspective view showing an installation state when the bottom surface of the antenna joint reception device of the present application is a mounting surface. As in the above-described example, the fixing screw 4a is screwed toward the wall to be attached to the wall surface 25.
As described above in detail, since the antenna joint receiving device of the present application is configured such that the mounting surface can be selected from either the bottom surface or the side surface of the case 1, the conventional antenna joint receiving device can be mounted according to the situation around the predetermined position to be mounted. Since it can be mounted even in a narrow space, the mounting legs 4 are formed integrally with the main body 2, so that they can be firmly mounted on the wall surface or the mounting wall surface of the storage box. The present invention is not limited to the above-described embodiment, and is implemented by appropriately changing the structure and arrangement of each part (for example, mounting leg part, ground terminal, etc.) without departing from the spirit of the present invention. It is also possible.
