The fitting part 201c gets over the raised part 34c and fits into the groove part 34a when the connection terminal board 30 is pressed downward by an external force. As a result, the connection terminal board substrate 30 is prevented from being detached by the raised portions 34 c of the temporary placement portion 201, and is thus securely fixed to the base member 200.

  A construction method of the operation terminal 1 configured as described above will be described. 12A to 12G are diagrams illustrating an outline of a construction method of the operation terminal 1.

  First, the operator installs the base member 200 using the screw 400 at the installation location of the wall K1 (FIG. 12A). Subsequently, the operator removes the connection terminal block substrate 30 from the cover member 100, inserts the connection terminal block substrate 30 into the temporary placement portion 201 of the base member 200, and fits the groove portion 34a into the fitting portion 201c. It mounts | wears with the placing part 201 (FIG. 12B). Thereafter, the operator connects the plurality of signal lines 300 to the corresponding terminals T of the terminal block 31 through the openings 202 (FIG. 12C).

  After connecting the plurality of signal lines 300 to the terminal block 31, the operator removes the connection terminal block substrate 30 from the temporary placement portion 201 and attaches the connector portion 33 of the connection terminal block substrate 30 to the connector portion 21 of the cover member 100. (FIG. 12D → FIG. 12E). At this time, the connection terminal block substrate 30 is connected to the main substrate 20 with the terminals T of the terminal block 31 oriented so that the main substrate 20 is orthogonal.

  After mounting the connection terminal block substrate 30 on the main substrate 20, the operator fixes the cover member 100 to the base member 200 with a filling member such as packing interposed (FIG. 12F → FIG. 12G). At this time, the worker accommodates the extra signal line 300 in the accommodating portion 204. Thereby, it is possible to prevent the extra signal line 300 from erroneously contacting the main substrate 20. Further, since the signal line 300 is accommodated in the accommodating portion 204, disconnection from an external force can be prevented and the thickness of the operation terminal 1 in the width direction can be reduced.

  According to the embodiment of the present invention described above, the base member 200 is combined so as to face the inner surface side of the cover member 100 to form the cover member 100 and the housing 10 and connect each of the plurality of signal lines 300. Since the temporary placement unit 201 temporarily places and fixes the connection terminal block substrate 30 when connecting to the terminal block substrate 30, wiring work for connecting each of the plurality of signal lines 300 to the terminal block 31 is easy and less. Can be done with effort.

  Furthermore, according to one embodiment of the present invention, when the main board 20 is replaced, the connection terminal block board 30 to which the signal line 300 is connected may be removed and mounted on the new main board 20. An erroneous connection between the signal line 300 and the terminal T that sometimes occurs can be reliably prevented.

  Further, according to one embodiment of the present invention, the temporary placement portion 201 is provided at a position on the inner surface side of the base member 200 facing the position where the connection terminal base substrate 30 is mounted on the main substrate 20, and the cover member 100 and When the base member 200 is mounted, a part of the connection terminal board substrate 30 is accommodated in the temporary placement part 201, so that the thickness of the operation terminal 1 can be reduced.

  Furthermore, according to one embodiment of the present invention, the height h in the direction in which the connection terminal block substrate 30 and the terminal block substrate 33 and the terminal block substrate 33 are placed on the plate portion 34 is greater than the width w of the terminal block substrate 33. When connecting the connection terminal block board 30 to the main board 20, the connection terminal block board 30 is connected to the main board 20 with the terminals T of the terminal block 31 oriented in a direction orthogonal to the main board 20, so that the operation terminal 1 Can be made thinner.

  In the embodiment of the present invention, the connection terminal block substrate 30 is mounted at the position in the longitudinal direction of the cover member 100. However, the connection terminal block substrate 30 may be mounted at a position in the short direction, for example. It can be appropriately changed according to the number of T and the shape of the operation terminal. Similarly, the position of the temporary placement portion 201 of the base member 200 can be changed as appropriate.

  In the embodiment of the present invention, the operation terminal used in the remote operation system for remotely operating the security device or the entrance management device has been described as an example. For example, for an apparatus such as an air conditioner, an illumination, and an electric curtain. The present invention can also be applied to an operation terminal that operates on / off or the like via a signal line.
