Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device suitable for effectively preventing crosstalk between a power line and a communication line drawn into the communication device.

[0002]

2. Description of the Related Art Generally, in a communication device used as a communication device for internal communication on a premises, an intercom that enables communication between a child device installed outdoors and a master device installed indoors. Has been put to practical use and has become widespread. In addition, recently, there is also one configured as a security system for crime prevention that has an emergency contact function to notify the outside of an emergency occurrence indoors as well as a call to the outside. It is strongly expected from the user's need to prepare for an emergency.

Normally, the intercom system used is composed of a base unit and a handset unit, and as is well known, the base unit is supplied with a drive power source for driving a main electric system circuit group for a call function. It is supposed to be done. In addition, the slave unit is supplied with drive power for activating circuits in the slave unit from the master unit to the slave unit via a communication line connecting the two units for bidirectional communication. . In this case, the driving power supplied to the child device is extremely smaller than the power supplied to the parent device. That is, the main unit is supplied with a strong power source that is a general household power source, and the slave unit is supplied with a weak power source.

Therefore, when an intercom is installed, a power supply power line for supplying high-power power to the base unit and a low-power power supply from the base unit to the handset and at the time of a call are used. By connecting both lines to the intercom, which are necessary for transmitting the audio signal, and the communication line,
We are trying to carry out wiring work associated with the installation.

Considering the place where the intercom is installed, it is desirable that the base unit is installed at a height that is convenient for use and in a space where the handset can be picked up more quickly. However, in order to install the master unit at the desired location, it is necessary to connect the power supply line and the communication line connecting the slave unit as described above. I won't.
In other words, the installation method of the parent device may differ depending on how the power supply line and the communication line, which must be connected to the parent device, are drawn inside the room. FIG. 6 shows a wiring state with the power supply line and the communication line, which has been widely used as described above.

FIG. 6 is an explanatory view for explaining a wiring state of a power supply line and a communication line necessary for connecting an intercom, and FIG. 6 (a) shows a switch box embedded in an indoor wall. Shows that each line is drawn in,
FIG. 6B shows a state in which each line is along an indoor wall and is wired by using a staple for locking.

Conventionally, there are at least two types of methods for pulling in a power supply line and a communication line. One is
As shown in FIG. 6A, at the time of new construction or remodeling, a wiring hole for installing an intercom is provided in advance in the indoor wall 50, and a switch box 51 (also referred to as a mounting box) is provided in the wiring hole. ) Is buried. At this time,
The power line 53 drawn from the inside of the building and the communication line 54 connected to the outdoor child device are prevented from coming into contact with each other by the contact prevention member 52 attached to the embedded switch box 51. It is designed to be pulled indoors.

The other is, as shown in FIG. 6B, the wiring hole for installing the intercom as described above is provided on the wall 5.
It corresponds to the case where it is not set in advance in 0,
The power line 53 and the communication line 54 drawn into the interior of the room
Are wired on the wall 50 at predetermined intervals so as not to come into contact with each other, and both wires are locked on the wall 50 by using a stop member 55 (referred to as a staple) formed of an insulating material or the like. In this way, both lines are placed on the wall 50.

Usually, the retracting method shown in FIG.
If wiring holes are provided on the wall 50 in advance, it is convenient for installation work of the intercom, but it is also conceivable to install the intercom in a limited space due to recent housing circumstances. In this case, since the wiring hole is not provided in advance, by adopting the retracting method shown in FIG. 6B, wiring is performed according to the mounting location desired by the user, and the master unit is installed. I am trying to do it. Therefore, in the case where the wiring hole is not provided due to the housing situation as described above, the wiring method of the power supply line and the communication line is adopted as shown in FIG. 6B. Depending on the mounting position where the intercom is installed, it is desirable that the power supply line from the power supply located at a position as close as possible be drawn in and wired so that the drive power is supplied.

Therefore, for example, as shown in FIG. 7, depending on the mounting height position of the base unit 60 of the intercom, the power line 53 is pulled in from the breaker 56 near the ceiling, and the normal state near the floor. It can be considered that the home power supply is pulled in from the home power supply set. That is, the base unit 60
The power line 53 may be pulled in from the upper part or the lower part. Normally, the power supply line 53 is pulled in from the breaker 56, but as shown in the drawing, the household conset 5
In some cases, the power supply line 53 may be pulled in from the inside of the main unit, and in consideration of the structure of the main unit 60 in which the power line 53 is drawn inside the main unit for connection, it is necessary to make the structure connectable from either the upper side or the lower side.

Therefore, a conventional method of connecting the main unit and the power supply line will be described with reference to FIG.

Conventionally, as a method of connecting the base unit 60 and the power supply line 53, as shown in FIG. 8A, the SL power supply terminal 58 for connecting to the power supply line 53 is used for connection. . The SL power supply terminal 58 is effective in connection with the power supply line 53 drawn from one direction on the connection terminal surface side because the connection terminal surface for connecting the power supply lines 53 is provided on only one side. Is. For this reason, the SL power supply terminal 58 is arranged inside the master device 60 in a direction corresponding to the direction of drawing the power supply line 53, that is, the direction corresponding to the upper part or the lower part of the master device 60, but it is normally drawn from the upper part. Since it is often the case, it is arranged upward as in the illustrated example.

However, if the SL power supply terminal 58 is arranged upward as described above, when the power supply line 53 is pulled in from the lower part of the base unit 60, as shown in FIG. 8B. The SL power supply terminal 58, which is disposed upward, is connected by drawing it from above, or as shown in FIG.
The only method is to connect the SL power supply terminal 58 while rotating it from the side. In addition, as shown in FIG. 8A, another SL power supply terminal 5 is provided for connection with the power supply line 53 from the lower part.
In some cases, by arranging and arranging 8a so as to face downward, connection corresponding to the power supply line 53 from the upper portion and the lower portion may be made. However, in this case, the SL power supply terminal becomes expensive, which causes inconvenience in an intercom that has a strong demand for cost reduction.

Therefore, when connecting to the power supply line 53 using one SL power supply terminal 58, the connection method as shown in FIG. 8B or 8C is conceivable. According to the method shown in (b), when the base unit main body including the bottom cover on which the SL power supply terminal 58 is disposed and the inner cover on which the main circuit board of the base unit 60 is mounted is combined, However, there is an inconvenience that a normal combination cannot be performed depending on the thickness of the power supply line 53 and that the lead wire is mixed with another lead wire. In addition, since the parent device 60 tends to be thin, it is not possible to reduce the thickness in such a wiring state.

As shown in FIG. 8C, the bottom cover is provided with a terminal board 59 for arranging the SL power supply terminals 58, and the SL power supply terminals are provided in the vicinity of the SL terminals on the terminal board. An output connector 59 is provided for supplying power from 58 to the main circuit board of the main body. Further, since the terminal block 59b for connecting to the taken-in communication line 54 is also provided, the power supply line 5 from the lower part as in the illustrated example.
If 8 is rotated from the side of the SL power supply terminal 58 and connected, the high-power power supply line 58 is at least a line (not shown) connected to the adjacent low-power communication line 54, the terminal board 59, and the output connector 59a. There is a risk of contact with any of them. If the high-power power line 58 and the low-power communication line 54 are in contact with each other, the call performance is adversely affected and, for example, noise is generated. Therefore, it is essential to connect the power supply line 53 taken in to the SL power supply terminal 58 so that the power supply line 58 and the communication line 54 do not touch each other.

By the way, as a means for preventing the power supply line and the communication line from touching each other, there has been conventionally proposed by JP-A-55-128957.

In this proposal, although not shown, a pair of power supply connection terminals and a pair of communication line connection terminals are diagonally arranged on the rear surface of the main unit to be installed, and they are buried in the wiring holes in the wall portion. In addition, a partition plate is provided in the switch box (wiring box) so as to separate the drawn power line and communication line. As a result, the power line and the communication line drawn out from the switch box are separated from each other, and by connecting to each terminal arranged diagonally, the contact of both lines is prevented and the connection process is smooth. It is supposed to be done.

However, in the above proposal, for example, FIG.
As described in (a), there is a problem that only the wiring state of the power line and the communication line drawn from the switch box embedded in the wall can be dealt with. Also, in the connection method according to this proposal, the power line and the communication line are not taken in and connected to the inside of the master unit, but they are connected via the connection terminals provided on the rear surface of the master unit. There is no regulation on how to prevent touching inside the machine. That is, there is a possibility that the power supply line and the communication line may touch each other inside the master unit.

[0019]

As described above, in the conventional communication device, due to the structure of the SL power supply terminal for pulling in and connecting the power supply line to the inside of the master unit, the pulling direction of the power supply line is either upper or lower. Only one direction can be connected satisfactorily, and even if the power line is pulled in from the lower direction in the opposite direction and connected, there is a risk that the power line and the communication line may come into contact with each other. However, there is a problem that the connection work cannot be performed smoothly.

Further, although a conventional technique for preventing the contact between the power supply line and the communication line has been proposed, it is different from the connection method in which the power line and the communication line are directly pulled into the inside of the master unit for connection, so that the inside of the device can be securely connected. There is also a problem that it is not possible to prevent contact between the power line and the communication line.

Therefore, the present invention has been made in view of the above-mentioned problems, and by providing a partition wall at a predetermined position inside the master unit, the power line drawn from the upper or lower part can be surely connected to the power line. It is an object of the present invention to provide a communication device capable of preventing contact between the power line and the communication line and facilitating connection work of the power line.
