By the way, even such an information communication device may break down after a long period of use, but the cause of the failure is not the power supply unit, which has a simple configuration, but the wireless communication unit and control unit, which have a complicated configuration. There are overwhelmingly many things.
In this regard, in the information communication devices described in Patent Documents 1 and 2, the power supply section, the wireless communication section, and the control section are provided in a common embedded unit. Even if only the control unit fails, it is necessary to remove the entire unit from the installation surface, repair or replace it, and then reattach the normal unit to the installation surface.
However, such work includes electrical work such as attaching and detaching commercial power cables and WAN-side communication cables to and from the unit, and therefore only specialists such as electricians can perform the work. Therefore, there is an inconvenience that it takes time to recover from the occurrence of failure, such as time loss due to arrangement of experts and schedule adjustment with the user. There is also the inconvenience that the cost tends to increase as much as the amount of arranging a specialist.

In view of this situation, the main object of the present invention is to provide an information communication device that can be restored quickly and at low cost even if it breaks down during use.

When the non-power-side split unit is attached to the power-side split unit, the power-side split unit and the non-power-side split unit are connected in a state in which power can be supplied from the power-side split unit to the non-power-side split unit. and a power connection for connecting the

According to this configuration, at least one of the wireless communication unit and the control unit is provided for the power supply side division unit that is provided with the power supply unit and can be installed in the installation surface in an embedded state, and the power supply side division unit is detachable from the power supply side division unit. By installing the non-power supply side split unit that can be attached to the power supply side split unit, the power supply side split unit and the non power supply side split unit are electrically connected at the power supply connection section, and power is supplied from the power supply side split unit to the non power supply side split unit. It is ready for supply and can be used as an information communication device capable of wireless communication with an external information communication terminal.

And even if a failure occurs while it is installed on the installation surface and used as an information communication device, the cause of the failure is overwhelmingly more frequent than the power supply part. If it is at least one of the split units, only the non-power supply side split unit that does not require work by an expert is removed and repaired or replaced, and the non-power supply side split unit after normalization is replaced with the power supply side split unit. By attaching to , recovery can be performed quickly and at low cost.

Furthermore, for example, even if at least one of the wireless communication unit and the control unit provided in the non-power supply side split unit needs to be replaced with a new one due to a change in the communication method, etc., the work by an expert is required. Only the non-power supply side split unit that is not needed is removed and replaced and attached to the power supply side split unit. By attaching it to the unit, it is possible to upgrade the version of the product quickly, easily, and at low cost.

A heat arm 45 for heat transfer is accommodated. The heat arm 45 is made of metal or the like and has good thermal conductivity.
A left-right center portion of the first plate portion 45A of the heat arm 45 is exposed to the outside to form a first heat radiation contact 44A. Further, the tip (rear end) of the second plate portion 45B of the heat arm 45 is in contact with the inner surface of the rear casing 33B having good thermal conductivity, which will be described later.
Therefore, the heat transferred from the second heat radiation contact 44B of the control-side split unit CU to the first heat radiation contact 44A of the power supply-side split unit PU (right-left central portion of the first plate portion 45A of the heat arm 45) The heat is transmitted from the tip (rear end) of the second plate portion 45B of the arm 45 to the rear side casing 33B, and the heat is radiated from the rear side casing 33B to the outside (internal space of the wall W).

In this way, the heat generated in the control-side split unit CU is transferred to the power-side split unit PU through the heat dissipation connecting portion 44, and then radiated from the power-side split unit PU to the outside (internal space of the wall W). Therefore, it is possible to appropriately avoid an excessive increase in temperature of the control-side split unit CU, which tends to increase in temperature in the operating state due to the provision of the wireless communication unit 24 and the control unit 25 that generate a large amount of heat.
The specific configuration such as the number, shape, and arrangement of the heat arms 45 can be changed as appropriate. They may be arranged so as to be in contact with each other, and the heat generated in the power supply side substrate 38 may also be radiated to the outside (internal space of the wall W) via the rear side casing 33B.

As described above, the information communication unit 2 includes a plurality of types of power supply side division units PU having a common basic configuration and different functions or specifications, and a plurality of types of control units having a common basic configuration and different functions or specifications. Since split units CU are prepared, each of multiple types of control side split units CU with different functions or specifications can be selectively attached to each of multiple types of power supply side split units PU with different functions or specifications. It has become.
Therefore, by appropriately combining an appropriate power-side split unit PU and an appropriate control-side split unit CU according to the user's request, etc., the product of the information communication unit 2 having the function or specification according to the user's request is configured. be able to.
