Then, as shown in FIGS. 7 and 8, when the control side division unit CU is attached to the power supply side division unit PU in the information communication unit 2, the power supply side division unit PU to the control side division unit CU A power supply connection unit 31 for connecting the power supply side division unit PU and the control side division unit CU in a state where power can be supplied to the power supply side is provided.
The power supply connection portion 31 has a metal flat plate-shaped first power supply contact 31A provided in the power supply side dividing unit PU and a metal bent plate shape (dogleg shape, etc.) provided in the control side dividing unit CU. ), And when the control side division unit CU is attached to the power supply side division unit PU, the first power supply contact 31A and the second power supply contact 31B come into contact with each other. Arranged to be connected.

Further, when the control side division unit CU is attached to the power supply side division unit PU in the information communication unit 2, the power supply side division unit PU and the control side division unit CU can communicate with each other (the present embodiment). Is provided with a communication connection unit 32 for connecting in a state where LAN communication and telephone communication are possible).
The communication connection unit 32 has a metal flat plate-shaped first communication contact 32A provided in the power supply side dividing unit PU and a metal bent plate shape (dogleg shape, etc.) provided in the control side dividing unit CU. ), And when the control side division unit CU is attached to the power supply side division unit PU, the first communication contact 32A and the second communication contact 32B come into contact with each other. Arranged to be connected.

Therefore, when the control side division unit CU is attached to the power supply side division unit PU and is in the attached state, the information communication unit 2 is automatically connected from the power supply unit 23 of the power supply side division unit PU through the power supply connection unit 31. Power can be supplied to the wireless communication unit 24 and the control unit 25 of the control side division unit CU, and communication between the power supply side division unit PU and the control side division unit CU is possible through the communication connection unit 32. ..

Further, as shown in FIGS. 7 and 8, when the control side division unit CU is mounted on the power supply side division unit PU, the heat generated by the control side division unit CU is transferred to the power supply side in the information communication unit 2. A heat dissipation connecting portion 44 for connecting the power supply side split unit PU and the control side split unit CU in a state where heat can be transferred to the split unit PU is provided.
The heat dissipation connection portion 44 is composed of a first heat dissipation contact 44A provided in the power supply side split unit PU and a second heat dissipation contact 44B provided in the control side split unit CU, and is formed in the power supply side split unit PU. On the other hand, when the control side dividing unit CU is mounted, the first heat radiating contact 44A and the second heat radiating contact 44B are arranged so as to be in contact with each other and connected to each other.
When the control side division unit CU is attached to the power supply side division unit PU and is in the attached state, the information communication unit 2 automatically moves from the control side division unit CU to the power supply side division unit PU through the heat dissipation connection unit 44. Electric heating is possible.

As an example, the second heat dissipation contact 44B provided in the control side division unit CU is arranged on the rear side surface of the control side board 39 (control board 39 constituting the wireless communication unit 24 and the control unit 25) described later. It is composed of a pad-shaped heat-good conductor, and is configured to be able to transfer heat from the control-side substrate 39 to the first heat dissipation contact 44A satisfactorily. In the operating state of the information communication unit 2, the control side board 39 provided in the control side division unit CU has a higher temperature than the power supply side board 38 provided in the power supply side division unit PU, which will be described later.

Further, the power supply side split unit PU has a first plate portion 45A extending in the left-right direction and a second plate portion 45B extending rearward from both left and right ends of the first plate portion 45A, and has a substantially U-shape in top view. The heat arm 45 for heat transfer is housed. The heat arm 45 is configured to have good thermal conductivity from a metal or the like.
Then, the left and right central portions of the first plate portion 45A of the heat arm 45 are exposed to the outside to form the first heat dissipation contact 44A. Further, the tip end (rear end) of the second plate portion 45B of the heat arm 45 is in contact with the inner surface of the thermally conductive rear casing 33B, which will be described later.
Therefore, the heat transferred from the second heat dissipation contact 44B of the control side split unit CU to the first heat dissipation contact 44A of the power supply side split unit PU (the left and right center portions of the first plate portion 45A of the heat arm 45) is heat. It is transmitted from the tip (rear end) of the second plate portion 45B of the arm 45 to the rear casing 33B, and heat is dissipated from the rear casing 33B to the outside (internal space of the wall W).

In this way, the heat generated in the control side division unit CU is transferred to the power supply side division unit PU through the heat dissipation connection portion 44, and then radiated from the power supply side division unit PU to the outside (internal space of the wall W). Therefore, since the wireless communication unit 24 and the control unit 25, which generate a large amount of heat, are provided, it is possible to appropriately avoid the excessive temperature rise of the control side split unit CU, which tends to rise in temperature in the operating state.
The specific configuration such as the number, shape, and arrangement of the heat arms 45 can be changed as appropriate. For example, inside the power supply side dividing unit PU, the first plate portion 45A of the heat arms 45 is also attached to the power supply side substrate 38. It 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 dissipated to the outside (internal space of the wall W) via the rear side casing 33B.

As described above, the information / communication unit 2 has a plurality of types of power supply side split unit PUs having a common basic configuration and different functions or specifications, and a plurality of types of control sides having a common basic configuration and different functions or specifications. Since the split unit CU is prepared, each of the plurality of types of control side split unit CUs having different functions or specifications can be selectively mounted on each of the plurality of types of power supply side split unit PUs having different functions or specifications. It has become.
