[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small radio device installed outdoors, and more particularly to a radio device fixed to a pole or a wall and used for a small radio base station having a communication range of several hundred meters.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional radio apparatus of this type includes a case body 21 of an outer case 2 for protecting a radio 1 from wind and rain in an external environment. The wireless device 1 is built in the housing body 21, and the inside of the outer housing 2 is liquid-tightly sealed by the housing cover 22. An antenna power supply line 7 and a power supply line 8 connected to the wireless device 1 are led out of the outer housing 2 via a waterproof electrical connector 10, and are provided upright at the upper end of the pole 4. Antenna 6 and a power supply device (not shown).

[0003]

In order to ensure the liquid-tightness of the outer housing 2 for protecting the wireless device 1, such a wireless device is connected to the antenna 6 via an electrical connector 10 having a waterproof structure. Connection is being made. For this reason, there is a problem that attenuation of an electric signal becomes remarkable in proportion to an increase in a cable length or a connection portion due to the laying of the power supply line 7 from the wireless device 1 to the antenna 6, and the connection structure becomes complicated. Also,
Since the antenna 6 needs to be supported on the pole 4 separately from the outer casing 2, the man-hour for installing the wireless device increases, and the cost increases, such as an increase in the number of regular maintenance items after the start of operation of the wireless device. Has become a factor. An object of the present invention is to provide a wireless device for outdoor installation that simplifies an antenna connection structure and suppresses attenuation of an electric signal, while reducing man-hours for installing the wireless device.

[0004]

According to the present invention, an outer casing for protecting an external environment for accommodating a radio device is formed of a material that transmits radio waves, and the radio device and an antenna connected to the radio device are separated from each other. Built in the housing, the outer housing is a pole, a tower,
The bottom is attached to the outdoor support structure such as the building wall and the opening
And a front of the housing body in which
Case cover attached to the opening in a liquid-tight manner via packing
And the radio and the antenna pass through the opening.
And can be built into the housing body, and
The power line to be connected is on the side located below the housing body
Drawn out of the outer casing through a hole opened in the surface
And the hole is sealed with a sealing material .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an embodiment of the present invention.
In FIG. 1, reference numeral 1 denotes a wireless device. An outer housing 2 is provided to protect the wireless device 1 from wind and rain, which is an outdoor environment, and the wireless device 1 is built in the outer housing 2. . The outer housing 2 includes a housing main body 21 and a housing cover 22 attached to the housing main body 21 to keep the inside liquid-tight. The housing body 21 and the housing cover 2 that constitute the outer housing
Reference numeral 2 employs a material that transmits radio waves at the transmission / reception frequency of the wireless device, for example, reinforced plastic (FRP).

[0006] The housing body 21 is fixed to a part of the pole 4 on which the wireless device is installed by a mounting bracket 5, and the wireless device 1 is built in the housing body 21. In addition, an antenna 6 is provided inside the outer housing 2 together with the wireless device 1, and is directly connected to the wireless device 1 without using a power supply line. Further, a power supply line 8 connected to the wireless device 1 is drawn out of the outer housing 2 through a hole 21a formed on the lower side of the housing main body 21, and is connected to a power supply device (not shown). In this case, after the power supply line 8 is drawn out, the hole 21a is subjected to waterproof treatment with the sealing material 9. In addition, the housing cover 22 is put on the opening of the housing body 21, the packing 3 is sandwiched between the openings, and the inside of the outer housing 2 is sealed in a liquid-tight state.

According to this configuration, the wireless device 1 and the antenna 6
Is sealed in the outer casing 2 in a liquid-tight manner, and is protected from an external environment such as wind and rain. In addition, since the antenna 6 is built in the outer housing 2 and is directly connected to the wireless device 1, the antenna feed line is not required, and there is no need to take waterproofing measures, thereby simplifying the configuration. Thus, the attenuation of the electric signal is suppressed. In addition, even if the antenna 6 is built in the outer housing 2, since the outer housing 2 can transmit radio waves, no problem occurs in transmission and reception. In addition, since the antenna 6 is built in the outer housing, the number of steps for installing the wireless device is reduced,
In addition, regular maintenance items after the start of operation of wireless devices can be reduced,
The cost can be reduced. Note that, in the above-described embodiment, an example in which the wireless device is mounted on a pole is shown. In this case, the mounting bracket 5 may be changed according to the installation location.

[0008]

As described above, according to the present invention, the outer casing for protecting the external environment is formed of a material that transmits radio waves, and the radio and the antenna are built in the outer casing. It is not necessary to lay an antenna feed line connecting the antenna and the antenna, and to perform waterproofing work and maintenance items after the start of operation, thereby simplifying the configuration and preventing attenuation of electric signals. In particular, since the outer casing is made of a reinforced plastic, it can be manufactured by molding, can be mass-produced, can be reduced in price, and is effective for application to a small wireless device. In addition, the outer housing is a housing body with the opening facing in the horizontal direction.
And liquid-tightly attached to the opening of this housing body via packing
The main body of the housing is
Mounted on high altitudes of outdoor support structures such as buildings, towers, and building walls
Even if the wireless device or antenna
The attachment and detachment can be easily performed. In addition, to radio
The connected power line is located on the side located below the housing body.
Can be pulled out through a hole opened in
Therefore, even when the outer casing is installed at a high place,
It becomes easy, and also,
Since the holes provided are sealed with a sealing material,
That water may enter the outer case through the power line.
Not even.
