  The present invention relates to a mounting structure of an electronic device having an input / output plug that is used by being attached to a ceiling or a wall surface of a building or an underground mall in the field of wireless communication or television broadcasting.

  In a wireless communication or terrestrial digital broadcast relay device, an electronic device having an input / output plug such as an antenna is attached to a ceiling or a wall surface of a building or an underground shopping mall (see, for example, Patent Document 1). .

  When the electronic device having the input / output plug is attached to a ceiling or a wall surface, it is conventionally attached as shown in FIGS.

  In the example shown in FIG. 6, a plurality of mounting bolts 14 are mounted in advance on the mounting surface of the input / output plug 12 in the electronic device 11, and input / output is performed on the plug through holes 15 and the bolt mounting holes 16 provided on the ceiling 13. Each of the plug 12 and the mounting bolt 14 is inserted, and a nut 18 is screwed and fixed to the tip of the mounting bolt 14 protruding from the back side of the ceiling 13 through a washer 17.

  Further, in the example shown in FIG. 7, a mounting plate 20 larger than the device case is attached in advance to the mounting surface of the input / output plug 12 in the electronic device 11, and the screw hole 21 provided in the ceiling 13 outside the device case. The mounting bolt 23 is fastened and fixed via the mounting plate 20 and the washer 22.

  In the conventional apparatus mounting method shown in FIG. 6 and FIG. 7, a bolt mounting hole 16 for mounting the mounting bolt 14 or a mounting bolt in addition to the plug through hole 15 for passing the input / output plug 12 through the ceiling 13. It is necessary to provide a screw hole 21 for attaching 23. Further, when mounting the mounting bolts 14 and 23, the mounting positions must be measured and the bolt mounting holes 16 and the screw holes 21 must be formed in the corresponding positions of the ceiling 13, which takes time for installation work and increases the cost. There was a problem of becoming. Furthermore, since it is necessary to open many holes in the ceiling 13, there is a problem that it is difficult to obtain installation permission from the manager or owner of the installation location.

  6 and 7 show the case where the electronic device 11 is attached to the ceiling 13, the same applies to the case where it is attached to a wall surface.

In addition, the conventional electronic device 11 is provided with an input / output waveguide, but the electronic device provided with the input / output waveguide can also be used by the method shown in FIG. 6 or FIG. Since it is attached to the ceiling 13 or the like, there is a problem similar to that of the electronic device 11 including the input / output plug 12.
