Therefore, the plate 30 can be easily attached and detached. Next, the screw 70 is inserted into the hole 21 and screwed into the boss 110 to fix the upper case 20 to the lower case 10.

(Second Embodiment)
Hereinafter, the housing structure of the wireless gateway 1 will be described in detail with reference to the accompanying drawings. The casing structure of the wireless specification gateway 1 is merely the replacement of the plate 30 with the plate 30A in the casing structure of the casing 100 of the wired specification gateway 1. Hereinafter, the plate 30A will be mainly described. The same components as those of the plate 30 are denoted by the same reference numerals.

  8, 9, and 10, the plate 30 </ b> A includes an insertion hole 36 for inserting the wireless antenna 80, and a cylindrical portion 37 that extends from the insertion hole 36 toward the inner side of the lower case 10 and holds the antenna. A step portion 370 that prevents the antenna 80 from being inserted beyond a predetermined position on the inner side of the cylindrical portion 37, and a front portion inside the cylindrical portion 37 that restricts the rotation of the antenna 80. And a restricting portion 371 to be used.

  8A, three insertion holes 36 are formed at both ends at substantially the same distance from the center in the longitudinal direction of the plate 30A. FIG. 8B is a diagram in which three antennas 80 are inserted into the insertion holes 36. The antenna 80 has a substantially rod shape. As shown in the antenna 80 at the end of the figure, the antenna 80 can be bent according to the installation status of the gateway 1 shown in FIG. FIG. 8C is a diagram in which one antenna 80 is inserted into the insertion hole 36 at one end. The insertion hole 36 in which the antenna 80 is not inserted can be closed by fitting the hole filling member 360.

  Hereinafter, the portion where the antenna 80 is inserted into the insertion hole 36 will be described in detail. FIG. 10 shows the insertion direction I of the antenna 80. 9 and 10, a slit 810 is formed in the insertion portion 81 of the antenna 80 to be inserted into the insertion hole 36, and a protrusion 82 is formed at the tip thereof toward the outside. When the insertion portion 81 of the antenna 80 is inserted into the insertion hole 36 and the cylindrical portion 37 is passed, the insertion portion 81 of the antenna 80 is inserted while being deformed inward, and when the projection 82 passes through the cylindrical portion 37, the insertion portion 81 is moved outward. It becomes difficult to come out in the direction opposite to the insertion direction I.

  A protrusion 811 is formed on the front side of the insertion portion 81 of the antenna 80. The step portion 370 is formed over the inner circumferential direction of the insertion hole 36. The projection 811 hits the stepped portion 370 and is prevented from being inserted when the projection 82 is inserted to a position where the projection 82 passes through the cylindrical portion 37 and the insertion portion 81 opens outward.

  The projections 82 make it difficult for the antenna 80 to come out in the direction opposite to the insertion direction I, and the projections 811 hit the stepped portion 370 to prevent the insertion, so that the antenna 80 is attached to the plate 30A without rattling. Since the antenna 80 is attached to the plate 30A by insertion, it is not necessary to use other members for attachment, and the aesthetic appearance when the antenna 80 is attached is improved.

  Further, the step portion 370 is formed with a restricting portion 371 that protrudes in a direction opposite to the insertion direction I. The restricting portion 371 is provided about a quarter of the circumferential direction of the step portion 370. When the antenna 80 rotates, the protrusion 811 hits the restricting portion 371 and the rotation is restricted. By restricting the rotation of the antenna 80, it is possible to prevent the direction of the bent antenna 80 from being greatly deviated.

  According to the embodiment, it is possible to provide a housing structure of the gateway 1 that can easily cope with the wired specification and the wireless specification having the antenna 80 outside and can reduce the manufacturing cost.

  In the embodiment described above, the shape of the gateway 1 is not limited to a thin, substantially rectangular parallelepiped shape, and may be another shape. For example, it may be a rectangular parallelepiped shape.

  Further, the corresponding specification is not limited to the wired and wireless specifications, and may be other specifications. For example, the replaceable plate may be a plate having a base for vertical installation and a plate not having the base.

  The solid housing structure in the embodiment is not limited to the gateway 1 and may be an electronic device. For example, it can be applied to alarm devices, communication devices, detectors, and the like.
