The sensor unit 37 of the human sensor unit 35 can be tilted, and the detection area can be arbitrarily adjusted by tilting the wiring device body 11 in the front-rear direction and the left-right direction.

  The human sensor 40 detects the intrusion of the person into the detection area, detects that the person has entered the detection area, turns on the open / close switch of the power supply board 44, and closes the power supply circuit to the lighting fixture. And turn on the luminaire.

  In addition, the ambient brightness is detected by the illuminance sensor 42, and by detecting that it is darker than the set brightness, the open / close switch of the power supply board 44 is turned on, the power supply circuit to the lighting fixture is closed, Turn on the luminaire.

  By operating the knob 48 of each setting device 47 provided on the front surface of the wiring fixture body 11 with the cover 13 removed, a combination of the control by the human sensor 40 and the control by the illuminance sensor 42 can be arbitrarily set.

  In the wiring device 10 of the present embodiment, the human sensor 40 is disposed in the light incident path from the lens 39, and the illuminance sensor 42 is disposed on the outer surface of the wiring device main body 11 at a position different from the light incident path from the lens 39. The human sensor 40 can accurately detect a person entering a predetermined detection area through the lens 39, and the illuminance sensor 42 can detect light that does not pass through the lens 39. The ambient brightness can be detected accurately without being affected by reflected light. As a result, the lighting fixture can be controlled with high accuracy.

  Further, the lens 39 and the illuminance sensor 42 of the human sensor 40 are arranged facing the lower surface side of the wiring fixture body 11, and a cover in which an opening 61 that faces the lens 39 and the illuminance sensor 42 is formed on the lower surface side. Since the wiring apparatus main body 11 is covered with 13, external light does not directly enter the illuminance sensor 42, and erroneous detection of the illuminance sensor 42 can be prevented.

  Further, since the protruding portion 27 is provided above the knob 48 arranged on the front surface of the wiring device main body 11, temporarily, rainwater or the like enters from between the upper part of the wiring device main body 11 and the cover 13, and the wiring device main body 11 Even if it is transmitted from the upper surface to the front surface, the protruding portion 27 prevents rainwater and the like from entering the portion of the knob 48, so that the wiring device main body 11 is inserted from the hole 26 of the wiring device main body 11 where the knob 48 is disposed. Can prevent rainwater and the like from entering inside. Further, even when an external force is applied to the cover 13, it is possible to prevent the cover 13 from receiving the cover 13 and coming into contact with the knob 48 and damaging the knob 48, the setting device 47 and the control board 46.

  In addition, since the terminal block 50 is separated from the wiring fixture body 11, and the terminal block 50 is configured to be attached to the terminal block mounting portion 29 of the wiring fixture body 11, the wiring fixture body 11 has high molding accuracy and low cost thermoplasticity. After being formed of a resin material, the holder 51 of the terminal block 50 that holds the charging unit including the terminal 52 can be formed of a thermosetting resin material having better heat resistance. Therefore, the wiring device main body 11 and the holder 51 of the terminal block 50 can be formed of appropriate materials, respectively, and the degree of freedom in selecting the material of the wiring device main body 11 can be ensured.

  Furthermore, in the case of the specifications of the wiring device 10 with different numbers of terminals, for example, when there is a terminal for a slave unit, a terminal block 50 corresponding to the number of terminals is prepared and the terminal block mounting portion 29 of the wiring device body 11 is prepared. What is necessary is just to attach, there is no change in the wiring instrument main body 11, and the wiring instrument main body 11 can be made shared.

  Furthermore, since the terminal block mounting portion 29 is inclined downward toward the outside of the wiring device main body 11, and the terminal block 50 can be mounted obliquely, rainwater or the like enters from between the upper portion of the wiring device main body 11 and the packing 12. Thus, even if it falls down the back side of the wiring device body 11, it can be prevented from entering the wiring device body 11.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
