  Here, a modification of the present embodiment will be described with reference to FIGS.

  In the following description, the x-axis direction shown in FIGS. 6 and 7 is the left-right direction, the y-axis direction shown in FIGS. 6 and 7 is the up-down direction, and the z-axis direction shown in FIG. 7 (the direction orthogonal to the paper surface of FIG. However, it is not intended to limit the direction in the actual use state.

  In the modification, the second communication adapter 3 is configured to perform wireless communication with an external communication device (not shown) using radio waves as a medium.

  The modified second communication adapter 3 includes a second connector 17b and a holding portion 36 on the lower surface.

  In the second communication adapter 3 shown in FIGS. 1 and 2, the first connector 17a is connected to the second connector 17b from the front, and the third connecting portion 38 is connected to the holding portion 36 from the front. On the other hand, in the second communication adapter 3 shown in the modified example, the second connector 17 b and the holding unit 36 are provided downward in the second communication adapter 3. That is, the first connector 17a is connected to the second connector 17b from below, and the third connecting portion 38 is connected to the holding portion 36 from below.

  For example, even if the distribution board 11 is installed at a high position from the floor such as near the ceiling, the operator can connect the first connector 17a and the third connecting portion 38 from the lower direction of the second communication adapter 3. Because it is possible, workability is improved. Further, when the first connector 17a and the third connecting portion 38 are easily attached / detached, stress applied to the connector portion and the connector holding portion during attachment / detachment is reduced, so that the durability of the connector portion and the connector holding portion is improved.

  Here, in the case where the second communication adapter 3 is configured to perform wired communication using an external communication device and a communication cable (not shown) as a medium, the second communication adapter 3 is formed on the lower portion of the front surface of the case 3a. The third connection part 30 is disposed inside the covered part 300. The third connection unit 30 has a connector and is mounted on the second circuit board in the second communication adapter 3. A hole 33 is formed on the lower surface of the cover part 300 so that the third connection part 30 is exposed. A communication cable (for example, a LAN (Local Area Network) cable or the like) (not shown) is connected to the third connection unit 30.

  For example, even if the distribution board 11 is installed at a high position from the floor such as near the ceiling, the operator can connect the communication cable from the lower direction of the second communication adapter 3 to the third connection unit 30. The workability is improved. Further, when the communication cable is easily attached / detached, the stress applied to the connector portion and the connector holding portion during attachment / detachment is reduced, so that the durability of the connector portion and the connector holding portion is improved.

  The third communication adapter 4 of the modified example includes a plurality (four in the modified example) of display units 40 on the front surface.

  The display unit 40 is disposed on the front surface of the third communication adapter 4 so as to be exposed in a region excluding the lower region of the third connection unit 30. In the modification, since the third connection unit 30 is provided on the left side of the second communication adapter 3, the display unit 40 is disposed on the right front surface of the third communication adapter 4. The display unit 40 has, for example, an LED (Light Emitting Diode). The display unit 40 displays a communication state of an arbitrary communication line set in advance among communication information transmitted and received by the third communication adapter 4. The display unit 40 is used, for example, for confirming whether or not communication with various devices can be normally performed during construction. For example, the display unit 40 is turned on when communication with an external communication device (not shown) is possible, flashes when communication is in progress, and turns off when communication is not being performed. Display the communication status using the display method. Since the display part 40 is not arrange | positioned below the 3rd connection part 30, it becomes difficult to hide the display part 40 with the communication cable connected to the 3rd connection part 30, and it is easy to see the lighting state of the display part 40 Become.
