Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall-mounting waterproof case for electronic equipment, such as a distributor of an antenna, in which electronic equipment is installed and mounted on a wall surface.

[0002]

2. Description of the Related Art A wall-mounting case for an electronic device, for example, a distributor of an antenna, in which an electronic device is disposed inside and is mounted on a wall surface, has an airtight interior in consideration of outdoor use. There is a waterproof structure that prevents the entry of rainwater. FIG. 2 (1) shows an example of such a case structure. Reference numeral 11 denotes a case housing, and a waterproof structure of the case housing 11 includes a pair of wall mounting holes 12 on the left and right below the inside of the case housing 11.
12 is perforated to the rear surface, and wall surface mounting screws 13 and 13 are held by screw holders 14 and 14.

When mounting the case housing 11 on the wall surface, however, as shown in FIG. 2 (2), the case housing 11 is brought into contact with the wall surface 15 at a predetermined position, and then the screw holders 14 and 14 are mounted on the wall surface. Wall mounting hole 1 by removing screws 13 and 13 respectively
It is fixed by screwing from 2 and 12 to the wall 15.

[0004]

However, in the structure of the case housing 11 as described above, when the wall surface mounting screw 13 is once removed from the screw holder 14 during the work of mounting the case housing 11 on the wall surface 15, Since it had to be screwed in more and the wall surface mounting screw 13 could be dropped, workability was poor.

Further, as shown in FIG. 3 using another case housing 11 ', when the mounting and fixing of the case housing 11' to the wall surface 15 'by the wall mounting screw 13' is swaying, the outside air and the case housing are swayed. It is considered that the airtightness between the inside of 11 ′ and the interior of 11 ′ is broken through the wall mounting hole 12 ′, and rainwater and the like may enter the inside of the case housing 11 through this wall mounting hole 12 ′. There is a risk that the operation of electronic circuits and the like arranged inside 11 'may be hindered.

The present invention has been made in view of the above circumstances, and an object thereof is to improve workability in mounting the case housing on the wall surface and to provide an airtight state inside the housing after mounting. (EN) Provided is a wall-mounting waterproof case for an electronic device capable of reliably maintaining the above.

[0007]

[Means for Solving the Problems] The present invention is to provide a device housing chamber having a waterproof structure in which electronic devices are arranged inside a case housing, and a screw drilled up to the back surface of the case housing. The screw mounting chamber in which the mounting hole is formed is spatially separated, and the mounting screw is attached by penetrating only the tip of the screw mounting hole in the screw mounting chamber. The case housing can be attached and fixed to the wall surface only by inserting it, and the screw mounting chamber having the screw mounting hole and the device accommodating chamber having the waterproof structure for disposing the electronic device have a separated structure. Therefore, rainwater or the like does not enter the equipment chamber through the screw mounting hole.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a partial sectional structure thereof.
Is a case housing, and inside the case housing 21, a device housing chamber having a completely waterproof structure for disposing electronic circuits and the like.
22 and a screw mounting chamber 23 formed so as to surround the device accommodating chamber 22 and having wall surface mounting holes 25, 25 for penetrating the pair of wall surface mounting screws 24, 24 are spatially separated. Formed.

As shown in FIG. 1 (B), the wall surface mounting holes 25, 25 are respectively fitted with wall surface mounting screws 24, 24 so that only the tips thereof penetrate shallowly.
The inside of the wall surface mounting hole 25 is divided by the thin film 27 into the wall surface 26 side and the inside of the housing. In this state, the thin film 27 causes the wall surface mounting hole 25 from the outside to the inside of the screw mounting chamber 23 of the case housing 11. No water will enter the area.

However, when the case housing 11 is attached to the wall surface 26, as shown in FIG.
After abutting against the wall surface 26 at a predetermined position, the wall surface mounting screw 24 is screwed in as it is, and the thin film 27 is pierced and screwed to the wall surface 26 as shown in FIG. 1 (C).

With such a structure, the wall surface mounting screw 24 for mounting the case housing 21 on the wall surface 26 as described above.
Is easy to handle and simply use this wall mounting screw 24
Since it can be screwed in as it is, workability is greatly improved.

Even if rainwater or the like enters the inside of the case housing 11 from the outside through the wall surface mounting hole 25, even if the mounting and fixing of the case housing 21 to the wall surface 26 by the wall surface mounting screws 24 is loosened, the wall surface mounting is performed. Since the wall surface mounting screw 24 having the hole 25 formed therein and the device accommodating chamber 22 in which the electronic device is arranged are spatially separated in the case housing 21, and the device accommodating chamber 22 has a waterproof structure. Rainwater and the like do not enter the equipment chamber 22.

[0014]

As described above, according to the present invention, a device housing chamber having a waterproof structure in which electronic devices are arranged inside the case housing, and a screw drilled to the back surface of the case housing are provided. Since the screw mounting chamber with the mounting hole is formed spatially separated, and only the tip of the screw mounting hole of the screw mounting chamber is inserted to mount the mounting screw, tighten the mounting screw. The case housing can be easily attached and fixed to the wall surface only by itself, and the screw mounting chamber in which the screw mounting hole is formed and the device accommodating chamber having a waterproof structure for disposing the electronic device are separated structures. Therefore, it is possible to provide a wall-mounting waterproof case for an electronic device that can reliably maintain the airtight state of the device housing chamber without rainwater or the like entering the device housing chamber through the screw mounting holes.
