[0011] Each drawing described in the following embodiments is a schematic drawing, and the size and thickness ratios of each component in each drawing do not necessarily reflect the actual dimensional ratios.

[0012] (1) Embodiment 1 (1-1) Overview An overview of a mounting member 100 according to the first embodiment will be described below with reference to FIGS.

[0013] The mounting member 100 (see FIG. 1) according to the first embodiment is a member for mounting an electric device 200 having at least one of a detection function for detecting a detection target and a load function for functioning as a load to a construction material M1 (see FIG. 3). The construction material M1 here includes parts of building structures such as ceiling materials and wall materials, piping (e.g., electrical conduits, wiring ducts, metal wire pipes, etc.) attached to building structures, embedded switch boxes, etc. In the following description, it is assumed that the mounting member 100 is used to mount the electric device 200 to the construction material M1 which is a piping.

[0014] As shown in Fig. 2, the mounting member 100 has a main body 11, a first mounting portion 12, a second mounting portion 13, and a separation assisting portion X1. As shown in Fig. 3, the main body 11 is cylindrical and has a first end E1 and a second end E2 in an axial direction D1. The first mounting portion 12 mounts the electric device 200 to the first end E1 of the main body 11. Meanwhile, the second mounting portion 13 mounts the second end E2 of the main body 11 to the construction material M1 as shown in Fig. 5. As shown in Figs. 4 and 5, the separation assisting portion X1 assists in the separation of the weak electric wire W1 and the strong electric wire W2 connected to the electric device 200 in the internal space Spa (see Fig. 3) of the main body 11.

[0015] As described above, the mounting member 100 of the first embodiment has an advantage that the weak electric wires W1 and the strong electric wires W2 can be easily accommodated apart in the internal space Spa of the main body 11.

[0016] (1-2) Detailed configuration (1-2-1) Electrical appliances The detailed configuration of the electric appliance A1 of the first embodiment will be described below with reference to Figs.

[0017] In the following description, as shown in Fig. 5, the axial direction D1 of the mounting member 100 in the electric appliance A1 is defined as the up-down direction, the side of the construction material M1 as viewed from the mounting member 100 is defined as the top, and the side of the mounting member 100 as viewed from the construction material M1 is defined as the bottom. However, these directions are not intended to define the mounting direction of the electric appliance A1.

[0018] 1, 2, and 6, the electric appliance A1 includes an electric appliance 200 and a mounting member 100 for mounting the electric appliance 200 to a construction material M1. With this configuration, the electric appliance 200 is mounted to the construction material M1 via the mounting member 100, so that even if the construction material M1 is a pipe having a smaller dimension in the axial direction D1 than the electric appliance 200, for example, as shown in FIG. 3, the electric appliance 200 can be mounted to the construction material M1.

[0019] (1-2-2) Electrical equipment The electric device 200 has at least one of a detection function for detecting a detection target and a load function for functioning as a load. The electric device 200 of the first embodiment has a detection function for detecting a detection target. More specifically, the electric device 200 of the first embodiment is a detection device 300. The detection device 300 is a detection device that detects a detection target in a detection area. Specifically, the detection device 300 has a function for detecting the presence or absence of a moving object such as a person in the detection area. In addition, when the electric device 200 has a load function for functioning as a load, the electric device 200 may be, for example, a lighting device or a hub device such as a switching hub.

[0020] As shown in Fig. 6, the detection device 300 includes a power supply circuit module 71, a sensor module 72 including an image sensor 34 and a plurality of infrared sensors 31 (see Fig. 2), and a communication module 73 that communicates with a communication device B1 described later. The power supply circuit module 71 converts AC voltage supplied from an external power source (e.g., a commercial power source) into a predetermined DC voltage and supplies it to the sensor module 72 and the communication module 73. The communication module 73 transmits detection information based on an output signal output by the sensor module 72 to the communication device B1. The power supply circuit module 71, the sensor module 72, and the communication module 73 are accommodated in a housing 33. Fig. 6 shows a schematic configuration of the detection device 300, but omits a plurality of infrared transparent members 32 (see Fig. 2).

[0021] That is, the detection device 300 of this embodiment is a device that detects the presence or absence of a moving object by using the image sensor 34 and the infrared sensor 31. However, the detection device 300 may be a device that uses only various sensors such as the image sensor 34, the infrared sensor 31, or the radio wave sensor, or may be a device that uses a combination of the above various sensors.

[0022] 2, the detection device 300 further includes a plurality of infrared transparent members 32 and a housing 33. The plurality of infrared transparent members 32 are disposed one by one below the plurality of infrared sensors 31. The housing 33 houses the plurality of infrared sensors 31 and holds the plurality of infrared transparent members 32.

[0023] Moreover, the detection device 300 further includes an attachment device 4 for attachment to the attachment member 100. In other words, the detection device 300 (electrical device 200) is attached to the attachment member 100. The attachment member 100 is attached to the construction material M1 (see FIG. 3). That is, the detection device 300 (electrical device 200) is attached to the construction material M1 via the attachment member 100.

[0024] (Infrared sensor) Each of the multiple infrared sensors 31 has a pyroelectric element, a signal processing unit, a mounting board, and a package. The pyroelectric element is a quad-type pyroelectric element. The pyroelectric element receives infrared rays and outputs a current signal according to a change in the amount of infrared rays received. The signal processing unit processes the output signal of the pyroelectric element. The signal processing unit includes an IC element (IC: Integrated Circuit). The signal processing unit includes a current-voltage conversion circuit, a voltage amplification circuit, a determination circuit, and an output circuit. The current-voltage conversion circuit is a circuit that converts a current signal, which is an output signal output from the pyroelectric element, into a voltage signal and outputs the voltage signal. The voltage amplification circuit is a circuit that amplifies and outputs a voltage signal of a predetermined frequency band (for example, 0.1 Hz to 10 Hz) out of the voltage signals output from the current-voltage conversion circuit. The voltage amplification circuit has a function as a bandpass filter. The function as a bandpass filter is a function that passes components of the predetermined frequency band out of the voltage signals output from the current-voltage conversion circuit and removes unnecessary frequency components that become noise. The determination circuit is a circuit that compares the voltage signal output from the voltage amplifier circuit with a preset threshold value and determines whether the voltage signal exceeds the threshold value. The output circuit is a circuit that outputs a human body detection signal as an output signal when the determination circuit determines that the voltage signal exceeds the threshold value. The pyroelectric element and the signal processing unit are mounted on a mounting board. The mounting board is, for example, a molded board. The package is a so-called can package.

[0025] In the first embodiment, the number of the multiple infrared sensors 31 is four. Note that, in Fig. 2, only three of the multiple infrared sensors 31 are illustrated, and the remaining infrared sensors 31 are not illustrated.

[0026] (Infrared transmitting material) The infrared transparent member 32 is a synthetic resin molded product. The material of the infrared transparent member 32 is, for example, polyethylene. More specifically, the material of the infrared transparent member 32 is polyethylene to which a white pigment is added. The white pigment is, for example, titanium oxide. The infrared transparent member 32 is formed by a molding method. The infrared transparent member 32 has electrical insulation properties. In the first embodiment, the number of the infrared transparent members 32 matches the number of the infrared sensors 31, and the infrared transparent members 32 correspond one-to-one to the infrared sensors 31. That is, in the first embodiment, the number of the infrared transparent members 32 is four.

[0027] 2, the infrared transparent member 32 is cylindrical with a hemispherical bottom surface protruding downward. A plurality of (two) claws 323 for attaching the infrared transparent member 32 to a housing 33 (more specifically, a decorative cover described later) are formed on a side wall of the infrared transparent member 32 at intervals in the circumferential direction.

[0028] (Image Sensor) The image sensor 34 captures an image and analyzes the captured image to detect the presence or absence of a person. When the image sensor 34 detects the presence of a person, it outputs a human body detection signal as an output signal. The image sensor 34 is disposed in the center of the lower surface of the housing main body 5 described later, as shown in FIG.

[0029] The image sensor 34 has an imaging element, an imaging lens, an image processing unit, a mounting board, and a package. The imaging element is, for example, a CCD (Charge Coupled Devices) image sensor or a CMOS (Complementary Metal-Oxide Semiconductor) image sensor. The imaging lens includes a plurality of single lenses. Each of the plurality of single lenses is, for example, a plano-convex lens. The image sensor 34 captures an image using the imaging element and the imaging lens. The image processing unit includes an IC element. The image processing unit includes a determination circuit and an output circuit. The determination circuit analyzes an image captured using the imaging element and the imaging lens to determine whether or not a person is present. The output circuit is a circuit that outputs a human body detection signal as an output signal when the determination circuit determines that a person is present. The imaging element and the signal processing unit are mounted on the mounting board. The mounting board is, for example, a molded board. The package accommodates the implementation board.

[0030] (housing) The housing 33 includes a housing main body 5 and a decorative cover 6. The housing main body 5 houses a power supply circuit module 71 and a sensor module 72. The decorative cover 6 has a plurality of window holes 61 that expose the image sensor 34 and each of the plurality of infrared transparent members 32. The decorative cover 6 is attached to the housing main body 5.

[0031] The housing main body 5 includes a body 51 and a cover 52. The housing main body 5 is configured by joining the body 51 and the cover 52. The body 51 and the cover 52 are joined by fitting a plurality of joining protrusions of the body 51 into a plurality of fitting holes of the cover 52.

[0032] The body 51 is a synthetic resin molded product. The material of the body 51 is, for example, ABS resin. The body 51 has electrical insulation properties. The body 51 is in the shape of a cylinder with a bottom.

[0033] As shown in FIG. 4, a first terminal block 511 and a second terminal block 512 are provided at the end (upper end) of the body 51 opposite to the cover 52 side. In FIG. 4, each of the weak electric wires W1 and the strong electric wires W2 is simply illustrated as a single cable, but each of the original weak electric wires W1 and the strong electric wires W2 is formed by bundling a plurality of cables. That is, in each of the original weak electric wires W1 and the strong electric wires W2, the ends of each of the plurality of cables are inserted into the connection holes provided in each of the first terminal block 511 and the second terminal block 512. As an example, the weak electric wires W1 are four cables consisting of at least two power lines and two signal lines, and are ten cables consisting of at most two power lines, two feeder lines, and six signal lines. Also, as an example, the strong electric wires W2 are two cables consisting of at least two power lines, and are four cables consisting of at most two power lines and two feeder lines.

[0034] The first terminal block 511 is a terminal block that is electrically connected to the connecting terminal of the sensor module 72 and has a connection hole into which the tip W11 of the weak electric wire W1 can be inserted. That is, when the tip W11 of the weak electric wire W1 is inserted into the connection hole of the first terminal block 511 and connected, the weak electric wire W1 is electrically connected to the connecting terminal of the sensor module 72 via the first terminal block 511. The first terminal block 511 has a connection release part 5111 that releases the connection between the connection hole and the tip W11 of the weak electric wire W1. The connection release part 5111 is a push button, and is configured so that the connection between the connection hole of the first terminal block 511 and the tip W11 of the weak electric wire W1 is released by the operator pressing the connection release part 5111.

[0035] Similarly, the second terminal block 512 is a terminal block that is electrically connected to the connecting terminal of the power supply circuit module 71 and has a connection hole into which the tip W21 of the strong power wire W2 can be inserted. That is, when the tip W21 of the strong power wire W2 is inserted into the connection hole of the second terminal block 512, the strong power wire W2 is electrically connected to the connecting terminal of the power supply circuit module 71 via the second terminal block 512. The second terminal block 512 has a connection release part 5121 that releases the connection between the connection hole and the tip W21 of the strong power wire W2. The connection release part 5121 is a push button, and is configured so that the connection between the connection hole of the second terminal block 512 and the tip W21 of the strong power wire W2 is released when the operator presses the connection release part 5121.

[0036] The cover 52 is a synthetic resin molded product. The material of the cover 52 is, for example, ABS resin. The cover 52 has electrical insulation properties. The cover 52 includes a cylindrical portion 521 and a flange portion 522. The flange portion 522 protrudes outward from one axial end (the lower end in FIG. 3) of the cylindrical portion 521. The outer periphery of the flange portion 522 is circular.

[0037] The decorative cover 6 is a synthetic resin molded product. The material of the decorative cover 6 is, for example, ABS resin. The decorative cover 6 has electrical insulation properties. The decorative cover 6 includes a disk-shaped base 60. The outer peripheral shape of the base 60 is circular. The inner diameter of the base 60 is slightly larger than the outer diameter of the flange portion 522.

[0038] The decorative cover 6 has multiple (four) locking claws for detachably attaching to (the flange portion 522 of) the housing main body 5. The multiple locking claws are provided on the upper surface of the base portion 60 of the decorative cover 6. The decorative cover 6 is attached to the flange portion 522 by inserting each of the multiple locking claws into multiple mounting holes in the flange portion 522 and hooking them onto the periphery of the mounting holes.

[0039] When attached to the flange portion 522, the decorative cover 6 covers the outer peripheral surface of the flange portion 522, the heads of the screws 41 described below, and the like.

[0040] In the decorative cover 6, a plurality of (five) window holes 61 are formed in the base 60. Hereinafter, among the five window holes 61, the window hole 61 exposing the infrared transparent member 32 is referred to as a first window hole 611, and each window hole 61 exposing one of the image sensors 34 is sometimes referred to as a second window hole 612. The opening shape of the first window hole 611 and the second window hole 612 is circular. The first window hole 611 is formed in the center of the base 60 of the decorative cover 6. The four second window holes 612 are arranged at equal intervals in the circumferential direction around the first window hole 611 so as to surround the first window hole 611.

[0041] (Mounting device) The mounting device 4 is a device for mounting the housing main body 5 to the mounting member 100. The mounting device 4 includes two screws 41 and two clamping members 42, as shown in FIG.

[0042] The screw 41 has a head 411 and a shaft portion 412 including a male thread portion 4121. The two shaft portions 412 are inserted into the two screw insertion holes 520 of the flange portion 522, respectively, and are located on the sides of the body 51.

[0043] The clamping metal fitting 42 has a female thread portion 421 which is fitted into the male thread portion 4121 , and is fitted into the male thread portion 4121 .

[0044] 3, the mounting device 4 has a pair of storage sections 513 (one in the figure) that protrude laterally from each of a pair of side walls of the body 51 and store the shaft portion 412 of the screw 41. In each of the pair of storage sections 513, a slit 5110 that allows the clamping metal fitting 42 to rotate in a plane perpendicular to the axial direction of the shaft portion 412 of the screw 41 is formed at the end (upper end in FIG. 2) opposite to the flange portion 522 side of each of the pair of storage sections 513. A method for mounting the detection device 300 (electrical device 200) to the mounting member 100 using the mounting device 4 will be described later in "(1-3-1) Method for mounting an infrared detection device to a mounting member".

[0045] (1-2-3) Mounting parts The detailed configuration of the mounting member 100 of the first embodiment will be described below with reference to FIGS.

[0046] As shown in FIGS. 2 and 3, the mounting member 100 includes a main body portion 11, a pair of shoulder portions (first mounting portions) 12, an upper bottom wall (second mounting portion) 13, and a partition wall 15.

[0047] The mounting member 100 further includes a separation auxiliary part X1 that assists in the separation of the weak electric wire W1 and the strong electric wire W2 connected to the detection device 300 (electrical device 200) in the internal space Spa of the main body 11. The separation auxiliary part X1 of the first embodiment includes a separation structure St1 that separates the weak electric wire W1 and the strong electric wire W2 in the internal space Spa of the main body 11. In other words, the mounting member 100 of the first embodiment includes the separation structure St1 as the separation auxiliary part X1. The separation structure St1 is a structure of the mounting member 100 that is provided in the internal space Spa of the main body 11 in order to separate the weak electric wire W1 and the strong electric wire W2. The inclusion of the separation structure St1 in the separation auxiliary part X1 makes it possible to reduce the amount of work that a worker (hereinafter simply referred to as "worker") who attaches the electric appliance A1 to the construction material M1 must do to separate the weak electric wire W1 and the strong electric wire W2. As a result, the mounting member 100 of the first embodiment has an advantage that the weak electric wires W1 and the strong electric wires W2 can be more easily accommodated apart in the internal space Spa of the main body 11.

[0048] (Main body) The main body 11 is formed in a cylindrical shape as shown in Fig. 3. The main body 11 is large enough to accommodate the detection device 300. The main body 11 has a first end E1 (lower end) and a second end E2 (upper end) in the axial direction D1. The "axial direction D1 of the main body 11" here refers to the direction along the central axis of the cylindrical shape of the main body 11.

[0049] The opening 112 on the first end E1 side (lower side) of the main body 11 in the axial direction D1 is circular when viewed from the axial direction D1. A pair of shoulders 12 is provided on the inner circumferential surface of the first end E1 of the main body 11. A detection device 300 (electrical device 200) is attached to the pair of shoulders 12. In other words, the pair of shoulders 12 are first mounting portions 12 that mount the electric device 200 to the first end E1 of the main body 11. When the detection device 300 (electrical device 200) is attached to the first mounting portions 12, the main body 11 houses the detection device 300.

[0050] On the other hand, the opening on the second end E2 side (upper side) of the main body 11 in the axial direction D1 is covered by an upper bottom wall 13 (see FIG. 2). The construction material M1 is attached to the upper bottom wall 13. In other words, the upper bottom wall 13 is a second mounting portion 13 that mounts the second end E2 of the main body 11 to the construction material M1.

[0051] As shown in FIG. 2, the opening 14 is provided in the main body 11 at a position closer to the second end E2 than the first end E1 in the axial direction D1. In other words, the opening 14 is provided in the main body 11 at a position closer to the second mounting portion 13 than the first mounting portion 12 in the axial direction D1. With this configuration, after the detection device 300 is attached to the construction material M1 via the mounting member 100, the worker can perform the work of separating the weak electric wire W1 and the strong electric wire W2 from the opening 14. That is, in the first embodiment, the separation auxiliary portion X1 includes the opening 14 in addition to the separation structure St1. As a result, the mounting member 100 of the first embodiment has the advantage that the weak electric wire W1 and the strong electric wire W2 can be separated and more reliably accommodated in the internal space Spa of the main body 11.

[0052] In the first embodiment, the opening 14 is provided at the second end E2 of the main body portion 11. That is, the opening 14 is provided so that the upper end of the opening 14 contacts the second attachment portion 13. In the first embodiment, two openings 14 are provided in the main body portion 11. The two openings 14 are provided in the second end E2 of the main body portion 11 in the circumferential direction of the main body portion 11. More specifically, the two openings 14 are provided in the second end E2 of the main body portion 11 so as to be continuously aligned along the circumferential direction of the main body portion 11. The dimension of each of the two openings 14 along the circumferential direction of the main body portion 11 is slightly smaller than half the circumference of the main body portion 11.

[0053] The main body 11 has a cover 111 that covers the two openings 14. In the first embodiment, the openings 14 are provided at the second end E2 of the main body 11, and therefore, when the cover 111 covers the openings 14, the upper end of the cover 111 corresponds to the second end E2 of the main body 11. Having the cover 111 on the main body 11 has the advantage that the detection device 300 (electrical device 200) accommodated inside the main body 11 can be protected.

[0054] The cover 111 is configured to be separable into two or more members in a direction intersecting the axial direction D1. Specifically, in the first embodiment, the cover 111 is configured to be separable into a first cover 1111 and a second cover 1112 in a direction intersecting the axial direction D1. As a result, there is an advantage that the cover 111 (the first cover 1111 and the second cover 1112) can be easily attached to the opening 14. Each of the first cover 1111 and the second cover 1112 is a plate member curved in a semicircular arc when viewed from the axial direction D1. The dimension of each of the first cover 1111 and the second cover 1112 along the circumferential direction of the main body 11 is approximately equal to half the circumference of the main body 11.

[0055] (Partition wall) As shown in Fig. 2, the partition wall 15 protrudes inward (downward) from the inner surface (lower surface) of the upper bottom wall 13 along the axial direction D1. As shown in Fig. 4, the partition wall 15 has a plate shape that is long in the radial direction (hereinafter also simply referred to as "radial direction D2") of the main body 11 as viewed from the axial direction D1, and is formed integrally with the upper bottom wall 13 of the main body 11. In the first embodiment, the partition wall 15 is formed so as to be curved in a Z-shape as viewed from the axial direction D1 as shown in Fig. 4. The partition wall 15 is formed so as to straddle an electric wire insertion hole 131 (described later) of the upper bottom wall 13 as shown in Fig. 7.

[0056] As shown in Figs. 4 and 5, the partition wall 15 divides the internal space Spa (see Fig. 3) of the main body 11 into a first arrangement space Sp1 in which the weak electric wire W1 is arranged and a second arrangement space Sp2 in which the strong electric wire W2 is arranged. That is, in the first embodiment, the separation structure St1 that separates the weak electric wire W1 and the strong electric wire W2 includes the partition wall 15. In other words, in the first embodiment, the separation auxiliary part X1 includes the separation structure St1 that is the partition wall 15. The main body 11 has the partition wall 15, which has the advantage that it is possible to simplify the work of separating the weak electric wire W1 and the strong electric wire W2 by a worker who attaches the electric appliance A1 to the construction material M1. In addition, the main body 11 has the partition wall 15, which has the advantage that the weak electric wire W1 and the strong electric wire W2 can be more easily stored separately in the internal space Spa of the main body 11.

[0057] As shown in Fig. 5, each of the first arrangement space Sp1 and the second arrangement space Sp2 is located closer to the second end E2 (upper end) than to the first end E1 (lower end) in the internal space Spa of the main body 11 (see Fig. 3). In other words, each of the first arrangement space Sp1 and the second arrangement space Sp2 is located closer to the second mounting portion 13 than to the first mounting portion 12 (see Fig. 2) in the internal space Spa of the main body 11. That is, each of the first arrangement space Sp1 and the second arrangement space Sp2 is located closer to the construction material M1. This has the advantage that it becomes easier for the worker to separate the weak electric wire W1 and the strong electric wire W2.

[0058] (First mounting part) As shown in FIG. 2, the pair of shoulders 12 (first attachment parts 12) are rectangular parallelepipeds elongated in the axial direction D1, and are formed integrally with the side walls of the main body part 11. Specifically, the pair of shoulders 12 protrude inward from the inner peripheral surface of the side walls of the main body part 11 along the radial direction D2. The pair of shoulders 12 also face each other in the radial direction D2 (see FIG. 7). Specifically, the pair of shoulders 12 are provided on the main body part 11 and face each other across the center of the main body part 11 when viewed from the axial direction D1. The distance between the pair of shoulders 12 is smaller than the diameter of the flange part 522 of the housing main body 5, and is a length that allows the body 51 to pass between the pair of shoulders 12. The length (height) of the pair of shoulders 12 in the axial direction D1 is slightly longer than the distance between the flange part 522 and the clamping metal fitting 42. A protrusion 121 is provided on each of the first surfaces (lower surfaces in FIG. 2) of the pair of shoulders 12. The pair of protrusions 121 are formed with a size that allows them to fit into a pair of recesses (not shown) provided on the upper surface of flange portion 522, respectively.

[0059] (Second mounting part) As shown in FIG. 7, an electric wire insertion hole 131 having a circular shape when viewed from the axial direction D1 is provided in the center of the upper bottom wall 13 (second mounting portion 13). The electric wire insertion hole 131 penetrates the upper bottom wall 13 in the thickness direction. A plurality of (here, ten) mounting holes 132 are provided around the electric wire insertion hole 131 in the upper bottom wall 13. Each of the multiple mounting holes 132 penetrates the upper bottom wall 13 in the thickness direction and is large enough to allow a mounting screw 400 (see FIG. 3) to be inserted therein. Here, the mounting screw 400 is a screw for screwing the upper bottom wall 13 to the construction material M1, that is, a screw for mounting the main body portion 11 to the construction material M1.

[0060] In the first embodiment, as shown in Fig. 7, the electric wire insertion hole 131 is partitioned by a partition wall 15 into a first electric wire insertion hole 1311 and a second electric wire insertion hole 1312. The first electric wire insertion hole 1311 is large enough to pass a weak electric wire W1 (see Fig. 5). The second electric wire insertion hole 1312 is large enough to pass a strong electric wire W2 (see Fig. 5).

[0061] Here, among the multiple mounting holes 132, a pair of mounting holes 132 facing each other across the center O1 of the main body 11 is referred to as a "mounting hole group." In other words, the upper bottom wall 13 has multiple mounting hole groups consisting of a pair of mounting holes 132 facing each other across the center O1 of the main body 11 and into which the mounting screws 400 are inserted. In the first embodiment, the upper bottom wall 13 has five mounting hole groups 10A, 10B, 10C, 10D, and 10E. The mounting hole groups 10A and 10B are located on a first straight line L1. The mounting hole groups 10C and 10D are located on a second straight line L2. The mounting hole group 10E is located on a third straight line L3.

[0062] The first straight line L1 is a straight line passing through the center O1 of the main body 11 as viewed from the axial direction D1. The second straight line L2 is a straight line that forms a predetermined angle θ1 with the first straight line L1 as viewed from the axial direction D1. Here, the predetermined angle θ1 is 45 degrees. Of course, the predetermined angle θ1 may be an angle other than 45 degrees. The third straight line L3 is a straight line that is perpendicular to the second straight line L2 as viewed from the axial direction D1. Here, "perpendicular" is not limited to strictly perpendicular to each other, but may be approximately perpendicular (for example, the angle at which the second straight line L2 and the third straight line L3 intersect is 90 degrees ± 5 degrees).

[0063] The multiple mounting hole groups 10A, 10B are aligned in the radial direction D2. Specifically, when looking at the upper side of the center O1 in FIG. 7, the mounting holes 132 of the mounting hole group 10A and the mounting holes 132 of the mounting hole group 10B are aligned on a first straight line L1, that is, in the radial direction D2. The same is true for the lower side of the center O1 in FIG. 7. The pitch P1 of the mounting hole group 10A and the pitch P1 of the mounting hole group 10B are different from each other. The "pitch P1" here is the diameter of an imaginary circle formed by connecting the center lines of a pair of mounting holes 132 belonging to any mounting hole group along the circumferential direction D3 of the main body 11 as viewed from the axial direction D1 (hereinafter simply referred to as the "circumferential direction D3").

[0064] The multiple mounting hole groups 10C, 10D are aligned in the radial direction D2. Specifically, looking at the upper side of the center O1 in Fig. 7, the mounting holes 132 of the mounting hole group 10C and the mounting holes 132 of the mounting hole group 10D are aligned on the second straight line L2, that is, in the radial direction D2. The same is true below the center O1 in Fig. 7. The pitch P1 of the mounting hole group 10C and the pitch P1 of the mounting hole group 10D are different from each other.

[0065] The multiple mounting hole groups 10A, 10C are aligned in the circumferential direction D3. Specifically, a pair of mounting holes 132 of the mounting hole group 10A and a pair of mounting holes 132 of the mounting hole group 10C are aligned in the circumferential direction D3. The multiple mounting hole groups 10B, 10D, 10E are aligned in the circumferential direction D3. Specifically, a pair of mounting holes 132 of the mounting hole group 10B, a pair of mounting holes 132 of the mounting hole group 10D, and a pair of mounting holes 132 of the mounting hole group 10E are aligned in the circumferential direction D3. That is, the two or more mounting hole groups 10A, 10C (or 10B, 10D) aligned in the circumferential direction D3 have the mounting hole group 10A (or 10B) located on the first straight line L1 and the mounting hole group 10C (or 10D) located on the second straight line L2.

[0066] Each of the multiple mounting holes 132 is an elongated hole that is long in the circumferential direction D3. In other words, in one or more of the two or more mounting hole groups 10A, ..., 10D aligned in the circumferential direction D3, each pair of mounting holes 132 has a predetermined length S1 in the circumferential direction D3 that is longer than the diameter of the mounting screw 400. In the first embodiment, in all of the mounting hole groups 10A, ..., 10E, each pair of mounting holes 132 has a predetermined length S1 in the circumferential direction D3. The predetermined length S1 differs for each of the multiple mounting hole groups 10A, ..., 10E.

[0067] (1-2-4) Communication Systems As shown in Fig. 6, the communication system C1 includes the above-mentioned electric appliance A1 and a communication device B1 that communicates with the electric appliance A1. In the first embodiment, since the electric device 200 of the electric appliance A1 is the detection device 300, the communication device B1 receives detection information from the communication module 73 in the detection device 300. The communication between the communication device B1 and the communication module 73 is, for example, wireless communication. That is, the communication module 73 transmits a wireless signal including the detection information to the communication device B1. In addition, the communication device B1 may transmit a wireless signal including control information for controlling the detection device 300 to the communication module 73.

[0068] When the electric device 200 has a load function that functions as a load, the communication device B1 receives monitoring information notifying the state of the electric device 200 from the communication module 73 in the electric device 200 of the electric appliance A1. That is, the communication module 73 transmits a wireless signal including the monitoring information to the communication device B1. The communication device B1 may also transmit a wireless signal including control information for controlling the electric device 200 to the communication module 73.

[0069] (1-3) Installation method (1-3-1) Method of mounting the infrared detector to the mounting member The detection device 300 (electrical device 200) can be attached to the mounting member 100 as follows. First, the body 51 of the detection device 300 is passed through the opening 112 of the mounting member 100 with the pair of clamping metal fittings 42 housed in the pair of slits 5110, respectively. Next, the pair of protrusions 121 of the mounting member 100 are fitted into a pair of recesses provided on the upper surface of the flange portion 522, thereby positioning the detection device 300 relative to the mounting member 100. Then, the pair of screws 41 are tightened using a jig such as a screwdriver. As a result, the pair of clamping metal fittings 42 are pressed by the pair of shoulder portions 12 (first mounting portions 12), respectively, and rotate while bending, and come into contact with the second surfaces (upper surfaces in FIG. 2) of the pair of shoulder portions 12 in the axial direction D1. Therefore, the pair of shoulder portions 12 are clamped between the pair of clamping metal fittings 42 and the flange portion 522 while receiving the elastic force of the pair of clamping metal fittings 42. In this manner, the detection device 300 is attached to the attachment member 100 .

[0070] (1-3-2) How to attach the mounting components to the construction materials The mounting member 100 can be attached to the construction material M1 (see FIG. 3) as follows. First, with the detection device 300 (electrical device 200) removed, the upper bottom wall 13 of the mounting member 100 is pressed against the construction material M1. At this time, the position of the mounting member 100 relative to the construction material M1 is adjusted so that a pair of mounting holes 132 in one of the multiple mounting hole groups 10A, ..., 10E overlaps with a pair of mounting holes M11 (see FIG. 3) provided in the construction material M1. Then, a pair of mounting screws 400 are inserted into the pair of mounting holes 132 and the pair of mounting holes M11 from the inside of the main body 11, respectively, and each of the pair of mounting screws 400 is tightened. As a result, the upper bottom wall 13 (second mounting portion 13) is fixed to the construction material M1, and the mounting member 100 is attached to the construction material M1.

[0071] At this time, as shown in Fig. 5, the weak electric wire W1 drawn from the inside of the construction material M1 through the electric wire hole M12 (see Fig. 3) is passed through the first electric wire insertion hole 1311 of the upper bottom wall 13. Similarly, the strong electric wire W2 drawn from the inside of the construction material M1 through the electric wire hole M12 is passed through the second electric wire insertion hole 1312 of the upper bottom wall 13. Thus, the tip W11 of the weak electric wire W1 and the tip W21 of the strong electric wire W2 are exposed to the inside of the main body 11.

[0072] Next, the tip W11 of the weak electric wire W1 is inserted into a connection hole provided in the first terminal block 511 of the detection device 300, and the tip W21 of the strong electric wire W2 is inserted into a connection hole provided in the second terminal block 512 of the detection device 300. At this time, the first arrangement space Sp1 in which the weak electric wire W1 is arranged and the second arrangement space Sp2 in which the strong electric wire W2 is arranged are partitioned by the partition wall 15. In other words, the mounting member 100 accommodates the weak electric wire W1 and the strong electric wire W2 in the internal space Spa of the main body 11 while separating them from each other.

[0073] Thereafter, the detection device 300 is attached to the mounting member 100 in accordance with “(1-3-1) Method for attaching an infrared detection device to a mounting member”, so that the detection device 300 is attached to the construction material M1 via the mounting member 100.

[0074] Here, the detection device 300 (electrical device 200) is attached to the mounting member 100 at one position, but the attachment position of the mounting member 100 to the construction material M1 is adjustable. Specifically, this attachment position can be adjusted, for example, by selecting one of the two or more mounting hole groups 10B, 10D, 10E arranged in the circumferential direction D3, or by adjusting the position of the mounting screw 400 inside the mounting hole 132. Therefore, by adjusting the attachment position of the mounting member 100 to which the electrical device 200 is attached to the construction material M1, it is possible to adjust the attachment position of the electrical device 200 to the construction material M1.

[0075] Then, after the detection device 300 is attached to the construction material M1 via the mounting member 100, the work of separating the weak electric wire W1 and the strong electric wire W2 is performed through the opening 14. For example, when the detection device 300 is attached to the mounting member 100, it is considered that the weak electric wire W1 passes through the gap between the partition wall 15 and the detection device 300 and is disposed in the second arrangement space Sp2 in which the strong electric wire W2 is disposed. In the above case, the cover 111 is removed from the opening 14, and the weak electric wire W1 is pulled from the opening 14 so that the weak electric wire W1 is disposed only in the first arrangement space Sp1. Similarly, when the detection device 300 is attached to the mounting member 100, it is considered that the strong electric wire W2 passes through the gap between the partition wall 15 and the detection device 300 and is disposed in the first arrangement space Sp1 in which the weak electric wire W1 is disposed. In the above case as well, the cover 111 is removed from the opening 14, and the high-power wire W2 is pulled from the opening 14 so that the high-power wire W2 is arranged only in the second arrangement space Sp2. After the above work is completed, the opening 14 is covered with the cover 111.

[0076] (1-4) Modification of the first embodiment The above-described first embodiment is merely one of various embodiments of the present disclosure. The above-described first embodiment can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. The following modified examples may be realized in appropriate combination. The same reference numerals are used to designate the same configuration as the above-described first embodiment, and the description thereof will be omitted.

[0077] (1-4-1) First Modification of the First Embodiment In the above-described first embodiment, the opening 14 is provided in the main body 11. However, as shown in Fig. 8, the opening 14 does not have to be provided in the main body 11a. In short, the separation auxiliary part X1 includes the opening 14 in addition to the separation structure St1 in the above-described first embodiment, but may include only the separation structure St1 (partition wall 15) as shown in Fig. 8.

[0078] As shown in FIG. 8, the electric appliance A2 in the first modified example of the first embodiment includes an electric appliance 200 (detection device 300) and an attachment member 100a for attaching the electric appliance 200 to a construction material M1.

[0079] The mounting member 100a includes a main body portion 11a, a pair of shoulder portions (first mounting portions) 12 (see FIG. 2), an upper bottom wall (second mounting portion) 13, and a partition wall 15.

[0080] The main body 11a is formed in a cylindrical shape. The main body 11a is large enough to accommodate the detection device 300. The main body 11a has a first end E1 (lower end) and a second end E2 (upper end) in the axial direction D1. The "axial direction D1 of the main body 11a" here refers to a direction along the central axis of the cylindrical shape of the main body 11a.

[0081] In the main body 11a, the second inner diameter R2 on the second end E2 side of the main body 11a is larger than the first inner diameter R1 on the first end E1 side of the main body 11a. More specifically, the main body 11a is formed such that the inner diameter increases from the first end E1 toward the second end E2. This configuration has the advantage that the internal space Spa on the second end E2 side of the main body 11a can be enlarged, making it easier for the main body 11a to accommodate the weak electric wire W1 and the strong electric wire W2 while separating them.

[0082] The main body 11a is different from the main body 11 of the first embodiment in that it does not have an opening 14 and does not have a cover 111. That is, in the first modified example of the first embodiment, the separation auxiliary part X1 includes only the separation structure St1 which is the partition wall 15.

[0083] A communication system C1 in the first modification of the first embodiment includes the above-mentioned electric appliance A2 and a communication device B1 that communicates with the electric appliance A2, similarly to the first embodiment.

[0084] (1-4-2) Second Modification of the First Embodiment In the above-described first embodiment, the main body 11 is provided with the opening 14. However, as shown in Fig. 9, the main body 11b may be configured to be separable into two or more members in a direction intersecting with the axial direction D1.

[0085] As shown in FIG. 9, the electric appliance A3 in the second modification of the first embodiment includes an electric appliance 200 (detection device 300) and an attachment member 100b for attaching the electric appliance 200 to a construction material M1.

[0086] The mounting member 100b includes a main body portion 11b, a pair of shoulder portions (first mounting portions) 12, an upper bottom wall (second mounting portion) 13, and a partition wall 15.

[0087] The main body 11b is formed in a cylindrical shape. The main body 11b is large enough to accommodate the detection device 300. The main body 11b has a first end E1 (lower end) and a second end E2 (upper end) in the axial direction D1. The "axial direction D1 of the main body 11b" here refers to a direction along the central axis of the cylindrical shape of the main body 11b.

[0088] The main body 11b is configured to be divisible into two or more members in a direction intersecting the axial direction D1. Specifically, in a second modified example of the first embodiment, the main body 11b is configured to be divisible into a first main body 113a and a second main body 113b in a direction intersecting the axial direction D1. In the second modified example of the first embodiment, the first main body 113a and the second main body 113b have the same shape. Note that the first main body 113a and the second main body 113b are not limited to being the same shape, and may be different shapes.

[0089] Each of the first main body portion 113a and the second main body portion 113b has a base portion 1131, an extension portion 1132, and a locking portion 1133. The base portion 1131 is a plate member curved in a semicircular arc shape when viewed from the axial direction D1. The extension portion 1132 extends from one end (upper end) of the base portion 1131 toward the upper bottom wall (second mounting portion) 13. The extension portion 1132 is a plate member curved in an annular shape when viewed from the axial direction D1. The thickness direction of the extension portion 1132 is along the axial direction D1. The locking portion 1133 is provided at the tip of the extension portion 1132 and is locked to the inner surface (lower surface) of the upper bottom wall 13. More specifically, the locking portion 1133 is provided at the tip of the extension portion 1132, in the center of the radial direction of the extension portion 1132. The "tip of the extension 1132" referred to here is one of the two ends of the base 1131 that face each other in the radial direction and that is not connected to one end (upper end) of the base 1131.

[0090] As described above, the main body 11b is configured to be divisible into two or more members in a direction intersecting with the axial direction D1. Therefore, after the detection device 300 is attached to the construction material M1 via the attachment member 100b, the worker can perform the work of separating the weak electric wire W1 and the strong electric wire W2 by dividing the main body 11b into two or more members. That is, in the second modified example of the first embodiment, the separation auxiliary part X1 includes, in addition to the separation structure St1, a structure in which the main body 11b is configured to be divisible into two or more members (i.e., a division structure). As a result, the attachment member 100b has the advantage that the weak electric wire W1 and the strong electric wire W2 can be more reliably accommodated apart in the internal space Spa of the main body 11b.

[0091] A communication system C1 in the second modification of the first embodiment includes the above-mentioned electric appliance A3 and a communication device B1 that communicates with the electric appliance A3, similarly to the first embodiment.

[0092] (1-4-3) Other Modifications of the First Embodiment Below, other variations of the above-mentioned embodiment 1 are listed. The following variations may be realized in appropriate combination.

[0093] In the above-mentioned embodiment 1, in one or more of the two or more mounting hole groups 10A, ..., 10D arranged in the circumferential direction D3, the pair of mounting holes 132 is an elongated hole having a predetermined length S1 in the circumferential direction D3, but this is not intended to be limiting. For example, in each of the mounting hole groups 10A, ..., 10D, the pair of mounting holes 132 may have multiple holes arranged in the circumferential direction D3 when viewed from the axial direction D1. With this configuration, it is possible to adjust the mounting position of the mounting member 100 relative to the construction material M1 along the circumferential direction D3 by selecting which of the multiple holes in the pair of mounting holes 132 the mounting screw 400 is inserted into.

[0094] In the above-described first embodiment, for example, two mounting hole groups, such as mounting hole groups 10A and 10B, are arranged in the radial direction D2, but this is not intended to be limiting. For example, three or more mounting hole groups may be arranged in the radial direction D2.

[0095] In the above-described first embodiment, for example, three mounting hole groups, such as mounting hole groups 10B, 10D, and 10E, are arranged in the circumferential direction D3, but this is not intended to be limiting. For example, two mounting hole groups or four or more mounting hole groups may be arranged in the circumferential direction D3.

[0096] In the above-described first embodiment, the electric device 200 is the detection device 300, but this is not intended to be limiting. For example, the electric device 200 may be another sensor such as a temperature sensor, or may be a security camera. In other words, the mounting member 100 may be mounted with an electric device 200 other than the detection device 300 (for example, a lighting device).

[0097] In the above-mentioned first embodiment, the electric device 200 is attached to the mounting member 100 in accordance with "(1-3-1) Method for attaching an infrared detection device to a mounting member", but this is not intended to be limiting. In other words, the mounting structure of the mounting member 100 for the electric device 200 is not limited to the pair of shoulder parts 12 in the above-mentioned first embodiment, and may have another mounting structure.

[0098] (2) Embodiment 2 (2-1) Overview Hereinafter, an electric appliance A4 (mounting member 100c) according to the second embodiment will be described with reference to Fig. 10. The same components as those in the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted.

[0099] In the mounting member 100 of the first embodiment, the separation auxiliary part X1 includes a separation structure St1 that separates the weak electric wire W1 and the strong electric wire W2 in the internal space Spa of the main body 11. On the other hand, in the mounting member 100c of the second embodiment, the separation auxiliary part X1 includes an auxiliary structure St2 that assists in separation of the weak electric wire W1 and the strong electric wire W2 on the second end E2 side of the main body 11c.

[0100] In short, the mounting member 100c of the second embodiment differs from the mounting member 100 of the first embodiment in that it has, as the separation auxiliary part X1, an auxiliary structure St2 which is the opening 14a instead of the separation structure St1.

[0101] (2-2) Detailed structure (2-2-1) Electrical appliances As shown in FIG. 10, the electric appliance A4 in the second embodiment includes an electric appliance 200 (a detection device 300a) and an attachment member 100c for attaching the electric appliance 200 to a construction material M1.

[0102] (2-2-2) Electrical Equipment The electric device 200 of the second embodiment is a detection device 300a having a detection function for detecting a detection target, similar to the detection device 300 of the first embodiment.

[0103] The detection device 300a includes a plurality of infrared transparent members 32 and a housing 33a. Similarly to the detection device 300, the detection device 300a further includes a power supply circuit module 71, a sensor module 72 including an image sensor 34 and a plurality of infrared sensors 31, a communication module 73 that communicates with a communication device B1 described later, and an attachment device 4 for attachment to the attachment member 100. Since the shape of the housing 33a in the detection device 300a of the second embodiment is only slightly different from the shape of the housing 33 in the detection device 300 of the first embodiment, a detailed description of the configuration of the detection device 300a will be omitted.

[0104] (2-2-3) Mounting parts The mounting member 100c includes a main body 11c, a pair of shoulders (first mounting portions) 12 (see FIG. 2), and an upper bottom wall (second mounting portion) 13a. The pair of shoulders 12 in the second embodiment are the same as those in the first embodiment, and therefore will not be described.

[0105] The main body 11c is formed in a cylindrical shape as shown in Fig. 10. The main body 11c is large enough to accommodate the detection device 300a. When the detection device 300a (electrical device 200) is attached to the first attachment portion 12, the main body 11c accommodates the detection device 300a. The main body 11c has a first end E1 (lower end) and a second end E2 (upper end) in the axial direction D1. The "axial direction D1 of the main body 11c" here refers to a direction along the central axis of the cylindrical shape of the main body 11c.

[0106] The opening of the main body 11c on the second end E2 side (upper side) in the axial direction D1 is covered by the upper bottom wall 13a. The construction material M1 is attached to the upper bottom wall 13a. In other words, the upper bottom wall 13a is the second mounting portion 13a that mounts the second end E2 of the main body 11c to the construction material M1.

[0107] Two electric wire insertion holes 131a having a rectangular shape when viewed from the axial direction D1 are provided in the center of the upper bottom wall (second mounting portion) 13a. Each of the two electric wire insertion holes 131a penetrates the upper bottom wall 13a in the thickness direction. Each of the two electric wire insertion holes 131a is large enough to pass one of the weak electric wire W1 and the strong electric wire W2 (see FIG. 5). The weak electric wire W1 is passed through one of the two electric wire insertion holes 131a, and the strong electric wire W2 is passed through the remaining electric wire insertion hole 131a.

[0108] A plurality of (here, 14) mounting holes 132a are provided around the electric wire insertion hole 131a in the upper bottom wall 13a. The mounting holes 132a in the second embodiment, like the mounting holes 132 in the first embodiment, all penetrate the upper bottom wall 13a in the thickness direction and are large enough to allow the insertion of mounting screws 400 (see FIG. 3). Here, the mounting screws 400 in the second embodiment are screws for screwing the upper bottom wall 13a to the construction material M1, that is, screws for attaching the main body 11c to the construction material M1.

[0109] The mounting member 100c further includes a separation auxiliary part X1 that assists in the separation of the weak electric wire W1 and the strong electric wire W2 connected to the detection device 300a (electrical device 200) in the internal space Spa of the main body part 11c. The separation auxiliary part X1 of the second embodiment includes an auxiliary structure St2 that assists in the separation of the weak electric wire W1 and the strong electric wire W2 on the second end E2 side of the main body part 11c. In other words, the mounting member 100c of the second embodiment includes the auxiliary structure St2 as the separation auxiliary part X1. The auxiliary structure St2 is a structure of the mounting member 100c that is provided on the second end E2 side of the main body part 11c to assist the worker in the work of separating the weak electric wire W1 and the strong electric wire W2. Note that the "second end E2 side of the main body part 11c" in the present disclosure means a position closer to the second end E2 than the first end E1 of the main body part 11c in the axial direction D1. Since the separation auxiliary part X1 includes the auxiliary structure St2, after the detection device 300a is attached to the construction material M1 via the attachment member 100c, an operator can separate the weak electric wire W1 and the strong electric wire W2. As a result, the attachment member 100c of the second embodiment has an advantage that the weak electric wire W1 and the strong electric wire W2 can be easily stored apart in the internal space Spa of the main body 11c.

[0110] As shown in FIG. 2, the opening 14a is provided in the main body 11c at a position closer to the second end E2 than the first end E1 in the axial direction D1. In other words, the opening 14a is provided in the main body 11c at a position closer to the second mounting portion 13a than the first mounting portion 12 in the axial direction D1. With this configuration, after the detection device 300a is attached to the construction material M1 via the mounting member 100c, the worker can perform the work of separating the weak electric wire W1 and the strong electric wire W2 on the second end E2 side of the main body 11c from each other through the opening 14a. That is, in the second embodiment, the auxiliary structure St2 includes the opening 14a. As a result, the mounting member 100c of the second embodiment has the advantage that the weak electric wire W1 and the strong electric wire W2 can be separated and more reliably accommodated in the internal space Spa of the main body 11c.

[0111] In the second embodiment, the main body 11c is provided with two openings 14a. Each of the two openings 14a is rectangular when viewed from the radial direction of the main body 11c. The two openings 14a are arranged to be spaced apart from each other along the circumferential direction of the main body 11c. More specifically, the two openings 14a are arranged to be equally spaced apart from each other along the circumferential direction of the main body 11c.

[0112] The main body 11c has a cover 111a that covers the opening 14a. More specifically, since the main body 11c has two openings 14a, the main body 11c has two covers 111a that cover corresponding openings 14a of the two openings 14a. Each of the two covers 111a is a plate member curved in an arc shape when viewed from the axial direction D1. Each of the two openings 14a is rectangular when viewed from the radial direction of the main body 11c. The shape of each of the two openings 14a when viewed from the radial direction of the main body 11c matches the shape of the corresponding opening 14a when viewed from the radial direction of the main body 11c. The main body 11c has the cover 111a that covers the openings 14a, which is advantageous in that it can protect the detection device 300a (electrical device 200) accommodated inside the main body 11c.

[0113] Each of the two covers 111a has a locking portion 1113 that is locked to the main body portion 11c. More specifically, each of the two covers 111a has two locking portions 1113 provided on side surfaces that face each other in the circumferential direction of the main body portion 11c. The two locking portions 1113 are locked to the main body portion 11c, whereby the cover 111a having the two locking portions 1113 is attached (fixed) to the main body portion 11c.

[0114] (2-2-4) Communication Systems The communication system C1 of the second embodiment includes an electric appliance A4 and a communication device B1 that communicates with the electric appliance A4. In the second embodiment, since the electric device 200 of the electric appliance A4 is a detection device 300a, the communication device B1 receives detection information from a communication module 73 (see FIG. 6) in the detection device 300a. The communication between the communication device B1 and the communication module 73 is, for example, wireless communication. That is, the communication module 73 transmits a wireless signal including the detection information to the communication device B1. The communication device B1 may also transmit a wireless signal including control information for controlling the detection device 300a to the communication module 73.

[0115] (2-3) Modification of the second embodiment The above-described second embodiment is merely one of various embodiments of the present disclosure. The above-described second embodiment can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. The following modified examples may be implemented in appropriate combination.

[0116] In the above-described second embodiment, the main body 11c is provided with two openings 14a, but it may be provided with one opening 14a, or with three or more openings 14a. That is, the number of openings 14a may be one or more. In this case, it is preferable that the number of covers 111a is equal to the number of openings 14a.

[0117] In the above-described second embodiment, the two openings 14a are arranged to be spaced apart from each other along the circumferential direction of the main body 11c. However, the two openings 14a may be arranged to be continuously arranged along the circumferential direction of the main body 11c.

[0118] (3) Embodiment 3 (3-1) Overview Hereinafter, an electric appliance A5 (mounting member 100d) according to the third embodiment will be described with reference to Figures 11 to 13. The same components as those in the first embodiment will be given the same reference numerals and the description thereof will be omitted.

[0119] In the mounting member 100 of the first embodiment, the separation auxiliary part X1 includes a separation structure St1 that separates the weak electric wire W1 and the strong electric wire W2 in the internal space Spa of the main body 11. On the other hand, in the mounting member 100d of the third embodiment, the separation auxiliary part X1 includes an auxiliary structure St2 that assists in separation of the weak electric wire W1 and the strong electric wire W2 on the second end E2 side of the main body 11d.

[0120] In short, the mounting member 100d of the third embodiment differs from the mounting member 100 of the first embodiment in that it does not have a separation structure St1, but has a division structure of the main body portion 11d as a separation auxiliary portion X1.

[0121] (3-2) Detailed structure (3-2-1) Electrical appliances As shown in FIG. 11, the electric appliance A5 in the third embodiment includes an electric appliance 200 (a detection device 300a) and an attachment member 100d for attaching the electric appliance 200 to a construction material M1.

[0122] (3-2-2) Electrical Equipment The electric device 200 of the third embodiment is a detection device 300a having a detection function for detecting a detection target, similar to the second embodiment. Since the detection device 300a of the third embodiment is similar to the second embodiment, detailed description of the configuration of the detection device 300a will be omitted.

[0123] (3-2-3) Mounting parts The mounting member 100d includes a main body 11d, a pair of shoulders (first mounting portions) 12, and an upper bottom wall (second mounting portion) 13b. The pair of shoulders 12 in the third embodiment are the same as those in the first embodiment, and therefore will not be described.

[0124] The main body 11d is formed in a cylindrical shape as shown in Fig. 11. The main body 11d is large enough to accommodate the detection device 300a. When the detection device 300a (electrical device 200) is attached to the first attachment portion 12, the main body 11d accommodates the detection device 300a. The main body 11d has a first end E1 (lower end) and a second end E2 (upper end) in the axial direction D1. The "axial direction D1 of the main body 11d" here refers to a direction along the central axis of the cylindrical shape of the main body 11d.

[0125] The opening of the main body 11d on the second end E2 side (upper side) in the axial direction D1 is covered by the upper bottom wall 13b. The construction material M1 is attached to the upper bottom wall 13b. In other words, the upper bottom wall 13b is the second mounting portion 13b that mounts the second end E2 of the main body 11d to the construction material M1.

[0126] Three wire insertion holes 131b are provided in the center of the upper bottom wall (second mounting portion) 13b, each of which is rectangular when viewed from the axial direction D1. Each of the three wire insertion holes 131b penetrates the upper bottom wall 13b in the thickness direction. Each of the three wire insertion holes 131b is large enough to pass one of the weak electric wire W1 and the strong electric wire W2 (see FIG. 5). The weak electric wire W1 is passed through one of the three wire insertion holes 131b, and the strong electric wire W2 is passed through one of the remaining two wire insertion holes 131b. This configuration has the advantage that the weak electric wire W1 and the strong electric wire W2 can be easily separated from each other regardless of the angle at which the electric device 200 is attached to the construction material M1.

[0127] A plurality of (here, 14) mounting holes 132b are provided around the electric wire insertion hole 131a in the upper bottom wall 13b. The mounting holes 132b in the third embodiment, like the mounting holes 132 in the first embodiment, all penetrate the upper bottom wall 13b in the thickness direction and are large enough to allow the insertion of a mounting screw 400 (see FIG. 3). Here, the mounting screw 400 in the third embodiment is a screw for screwing the upper bottom wall 13b to the construction material M1, that is, a screw for attaching the main body 11d to the construction material M1.

[0128] The mounting member 100d further includes a separation auxiliary part X1 that assists in the separation of the weak electric wire W1 and the strong electric wire W2 connected to the detection device 300a (electrical device 200) in the internal space Spa of the main body part 11d. The separation auxiliary part X1 of the third embodiment includes an auxiliary structure St2 that assists in the separation of the weak electric wire W1 and the strong electric wire W2 on the second end E2 side of the main body part 11d. In other words, the mounting member 100d of the third embodiment includes the auxiliary structure St2 as the separation auxiliary part X1. The auxiliary structure St2 is a structure of the mounting member 100d that is provided on the second end E2 side of the main body part 11d to assist the worker in the work of separating the weak electric wire W1 and the strong electric wire W2. Note that the "second end E2 side of the main body part 11d" in the present disclosure means a position closer to the second end E2 than the first end E1 of the main body part 11d in the axial direction D1. Since the separation auxiliary part X1 includes the auxiliary structure St2, after the detection device 300a is attached to the construction material M1 via the attachment member 100d, an operator can separate the weak electric wire W1 and the strong electric wire W2. As a result, the attachment member 100d of the third embodiment has an advantage that the weak electric wire W1 and the strong electric wire W2 can be easily stored apart in the internal space Spa of the main body part 11d.

[0129] As shown in FIG. 12, the main body 11d has a division structure that can be divided in the axial direction D1 into a first division body 114a having a pair of shoulder portions (first mounting portion) 12 and a second division body 114b having an upper bottom wall (second mounting portion) 13b.

[0130] The second divided body 114b has a pair of locking portions 1141 (see FIG. 12) that are locked to a pair of protrusions 1142 (see FIG. 11) provided on the first divided body 114a. The pair of locking portions 1141 are locked to the pair of protrusions 1142, whereby the first divided body 114a is attached to the second divided body 114b. The pair of protrusions 1142 are provided so as to protrude inward at an end (upper end) of the inner surface of the first divided body 114a on the second divided body 114b side. The pair of protrusions 1142 are provided at positions facing each other in the radial direction of the first divided body 114a (main body 11d). The pair of locking portions 1141 are hook-shaped when viewed from the radial direction of the second divided body 114b (main body 11d). The pair of locking portions 1141 are provided on the inner surface of the second divided body 114b, and the ends (upper ends) of the pair of locking portions 1141 opposite the first divided body 114a side are connected to the upper bottom wall 13b. The pair of locking portions 1141 are provided at positions facing each other in the radial direction of the second divided body 114b (main body portion 11d).

[0131] According to this configuration, after the detection device 300a is attached to the first divided body 114a and the second divided body 114b is attached to the construction material M1, the worker can perform the work of separating the weak electric wire W1 and the strong electric wire W2 at the second end E2 side of the main body 11d. After that, the worker can attach the first divided body 114a to the second divided body 114b in a state in which the weak electric wire W1 and the strong electric wire W2 are separated. That is, in the third embodiment, the auxiliary structure St2 includes a division structure of the main body 11d. As a result, the mounting member 100d of the third embodiment has the advantage that the weak electric wire W1 and the strong electric wire W2 can be more reliably accommodated apart in the internal space Spa of the main body 11d.

[0132] In the third embodiment, as shown in Fig. 13, the first divided body 114a is formed such that, when viewed from a direction intersecting (here, perpendicular to) the axial direction D1 in a state in which the electric device 200 (detection device 300a) is attached to the first divided body 114a by the first attachment portion 12, the first terminal block (first connection portion) 511 and the second terminal block (second connection portion) 512 of the electric device 200 are exposed from the first divided body 114a. More specifically, the first divided body 114a is formed such that, when viewed from a direction intersecting (here, perpendicular to) the axial direction D1 in a state in which the electric device 200 is attached to the first divided body 114a by the first attachment portion 12, the connection release portion 5111 of the first terminal block 511 and the connection release portion 5121 of the second terminal block 512 are exposed from the first divided body 114a. With this configuration, the worker can more easily separate the weak electric wire W1 and the strong electric wire W2 at the second end E2 side of the main body 11d after the detection device 300a is attached to the first divided body 114a and the second divided body 114b is attached to the construction material M1. As a result, the mounting member 100d of the third embodiment has the advantage that the weak electric wire W1 and the strong electric wire W2 can be separated and more easily accommodated in the internal space Spa of the main body 11d. Note that the first terminal block (first connection part) 511 and the second terminal block (second connection part) 512 of the third embodiment are the same as those of the first embodiment, and therefore will not be described.

[0133] (3-2-4) Communication Systems The communication system C1 of the third embodiment includes an electric appliance A5 and a communication device B1 that communicates with the electric appliance A5. In the third embodiment, since the electric device 200 of the electric appliance A5 is a detection device 300a, the communication device B1 receives detection information from a communication module 73 (see FIG. 6) in the detection device 300a. The communication between the communication device B1 and the communication module 73 is, for example, wireless communication. That is, the communication module 73 transmits a wireless signal including the detection information to the communication device B1. The communication device B1 may also transmit a wireless signal including control information for controlling the detection device 300a to the communication module 73.

[0134] (3-3) Modification of the third embodiment The above-described third embodiment is merely one of various embodiments of the present disclosure. The above-described third embodiment can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved. The following modified examples may be implemented in appropriate combination.

[0135] In the above-mentioned embodiment 3, the mounting member 100d does not have a separation structure St1, and has the division structure of the main body portion 11d as the separation auxiliary portion X1. However, the mounting member 100d may have the separation structure St1, which is the partition wall 15, as the separation auxiliary portion X1 in addition to the division structure of the main body portion 11d. In other words, the separation auxiliary portion X1 of the mounting member 100d may further include the separation structure St1, which is the partition wall 15, in addition to the auxiliary structure St2, which is the division structure of the main body portion 11d. In short, the mounting member 100d of embodiment 3 may have the partition wall 15 protruding inward (downward) from the inner surface (lower surface) of the upper bottom wall 13b along the axial direction D1, as in embodiment 1.

[0136] In the above-mentioned embodiment 3, three electric wire insertion holes 131b are provided in the center of the upper bottom wall (second mounting portion) 13b, but two electric wire insertion holes 131b may be provided, or four or more electric wire insertion holes 131b may be provided. That is, it is preferable that at least two or more electric wire insertion holes 131b are provided in the center of the upper bottom wall (second mounting portion) 13b. However, one electric wire insertion hole 131b may be provided in the center of the upper bottom wall (second mounting portion) 13b, and in this case, it is preferable to have a partition wall that separates the weak electric wire W1 and the strong electric wire W2 in the internal space of the main body 11.

[0137] In the above-described third embodiment, the first divided body 114a is attached to the second divided body 114b by the pair of locking portions 1141 being locked to the pair of protrusions 1142, but this is not intended to be limiting. In other words, the attachment structure for attaching the first divided body 114a to the second divided body 114b is not limited to the pair of locking portions 1141 and the pair of protrusions 1142, and may have another attachment structure.
