Description

  The present invention relates to a communication device used as an outdoor wireless base station of a mobile phone system, and more particularly to a communication device capable of easily performing installation work.

  Communication equipment used as an outdoor wireless base station of a mobile phone system is generally used by being fixed to a pole or a steel tower to which an antenna is attached, so that installation work at a high place is required. On the other hand, communication equipment for outdoor wireless base stations tends to be miniaturized year by year, but still has a mass of several tens of kilograms. For this reason, the installation work of a communication apparatus becomes very difficult. That is, since a communication device having a large mass must be lifted to a high place and fixed on a pole or the like, the installation work becomes very difficult.

  By the way, in order to facilitate the installation work of the communication device, it can be considered that the communication device is divided into a plurality of parts and each part is accommodated in a separate casing. By doing in this way, handling becomes easy and it becomes possible to perform installation work easily.

  As a conventional technique for dividing a communication device into a plurality of parts, for example, the following techniques are known (see, for example, Patent Documents 1 and 2).

  The conventional technique described in Patent Document 1 divides a communication device into a high-frequency part to which an antenna is connected and other parts, and the high-frequency part and the other parts are respectively a high-frequency part casing and a main casing. To accommodate. The high-frequency unit housing and the main housing are detachable by a clasp, and when both are separated, both can be connected by a cable.

Further, the conventional technique described in Patent Document 2 divides a communication device into a cooling part and other parts, and accommodates the cooling part and other parts in the cooling part casing and the main body casing, respectively. I am doing so. The cooling unit housing is substantially L-shaped when viewed from the side, and has a structure that serves as a base for supporting the main body housing. During the installation work of the communication device, the cooling unit casing is fixed to the pole by a metal band or the like, and the main unit casing is assembled on the L-shaped base constituted by the cooling unit casing. Integrated.

  By the way, when performing installation work at a high place, it is important for safety to prevent the casing from falling. However, the conventional technique described in Patent Document 1 does not consider this point at all.

  On the other hand, in the conventional technique described in Patent Document 2, the shape of the cooling unit casing is substantially L-shaped, and the main body casing is mounted on the L-shaped pedestal. The risk of the body falling can be greatly reduced. However, since it is necessary to make the housing shape substantially L-shaped, there is a problem that costs are increased.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a communication device that can perform installation work at a high place easily and safely with an economical configuration.

The first communication device according to the present invention is:

On the back surface of the modem unit housing, it has a column member mounting portion to which a column member is mounted,
On the bottom surface of the opening, having a protrusion and a screw hole,
The upper fastening member has a guide hole that fits with the protrusion at a portion corresponding to the protrusion to be inserted into the opening, and is used for inserting a bolt that communicates vertically with the portion corresponding to the screw hole. It has a hole.

  According to this configuration, the upper mounting member fixed to the back surface of the transmission / reception amplification unit housing is inserted into the opening provided on the front surface of the modulation / demodulation housing, so that the protrusion provided on the bottom surface of the opening is provided. Since the guide hole provided in the upper fastening member is fitted, even if the operator removes his / her hand from the transmission / reception amplification unit case, the transmission / reception amplification unit case can be prevented from falling.

Moreover, in order to enable the second communication device according to the present invention to install the transmission / reception amplification unit casing alone on the antenna pole or the like, in the first communication device,
A columnar member attaching portion to which a columnar member is attached is provided on the rear surface of the transmission / reception amplification unit casing.

Further, a third communication device according to the present invention is the second communication device,
An upper surface of the modulation / demodulation unit housing is configured by a sunshade that can be opened and closed.

Furthermore, in order to facilitate maintenance, the fourth communication device according to the present invention is the third communication device,
The transmission / reception amplifier housing has a maintenance door on its front surface,
The modem unit housing has a maintenance door on a side surface thereof.

In addition, the fifth communication device according to the present invention has an economical configuration so that installation work at a high place can be performed easily and safely.

On the bottom surface of the opening, having a protrusion and a screw hole,
The upper fastening member has a guide hole that fits with the protrusion at a portion corresponding to the protrusion to be inserted into the opening, and is used for inserting a bolt that communicates with the screw hole in a vertical direction. It has a hole.

  The first effect of the present invention is that an installation work at a high place can be easily and safely performed with an economical configuration.

  The reason is that the upper fastening member fixed to the back surface of the transmission / reception amplifier housing is inserted into the opening provided on the front surface of the modulation / demodulation housing, so that the protrusion on the bottom surface of the opening This is because the guide hole provided in the mounting member is fitted and has a structure for preventing the fall. In other words, since it is only necessary to provide an attachment portion for the upper fastening member in the transmission / reception amplifier housing and provide an opening in the modem housing, the shape viewed from the side of the housing must be L-shaped. The cost can be reduced compared to the technology.

  The second effect of the present invention is that the transmission / reception amplifier housing is installed in the vicinity of the antenna in order to reduce the power loss due to the cable between the transmission / reception amplifier housing and the antenna, and the modem housing for easy maintenance. It can be installed in a state where the transmission / reception amplification unit casing and the modulation / demodulation unit casing are separated from each other so that the antenna is installed below the antenna pole.

  The reason is that it has a columnar member attaching portion to which the columnar member is attached on the back of the transmission / reception amplification unit casing and the modem unit casing.
