(Embodiment 1)
(1) Overview First, an overview of the wiring device system 10 according to the present embodiment will be described with reference to FIGS. 1A and 1B.

The wiring device system 10 according to the present embodiment is fixed to the construction target 3 and performs at least one of supplying power to the load 4 and controlling the load 4. The "construction target" in the present disclosure is an object to which the wiring equipment system 10 is fixed, such as a structure such as a wall, ceiling, or floor, or fixtures (fittings) such as a desk, shelf, or counter stand. ), etc. In addition, a "load" as used in the present disclosure refers to equipment (including equipment, devices, and systems) to which power is supplied from the wiring equipment system 10 or controlled by the wiring equipment system 10, such as lighting equipment. , air conditioning equipment, refrigerators, ventilation fans, information processing equipment, mobile terminals, etc.

That is, the wiring device system 10 is a system used as a "wiring device" such as an outlet, a switch device, a light control device, a human sensor device, a timer device, or the like. For example, the wiring device system 10 that functions as an outlet is used while being fixed to a construction target 3 such as a wall of a building, and supplies power to a load 4 such as an air conditioner. Further, for example, the wiring equipment system 10 having a function as a switch device is used while being fixed to a construction target 3 such as a building wall, and is used by turning on/off electricity to a load 4 such as a lighting equipment. , controls the load 4.

Such a wiring device system 10 is used, for example, in a facility. In this embodiment, a case is illustrated in which the wiring device system 10 is used in a residential facility such as an apartment complex or a single-family house. The wiring device system 10 is not limited to this example, and may be used in non-residential facilities such as office buildings, stores, schools, welfare facilities, commercial facilities, theme parks, hospitals, hotels, or factories. In short, a large number of devices serving as loads 4 are used in various facilities, regardless of whether they are residential facilities or non-residential facilities, and the wiring equipment system 10 can be used to supply or control power to these devices. Furthermore, the wiring equipment system 10 is not limited to being used indoors, but may be used in a specific space in an outdoor facility such as a park or a ground. In outdoor applications, the wiring device system 10 preferably satisfies predetermined performance in terms of waterproofness (including rainproofness and dripproofness), weatherproofness, and the like.

In this type of facility, a typical wiring device is fixed to a construction target 3 such as a wall using a mounting member such as a switch box, for example. General wiring devices have terminals for connecting wiring (electrical wires), and the wiring routed inside the wall (construction target 3) is connected to the terminal, allowing the wiring to be connected. It is electrically connected to a power source or load 4 via the power supply. For example, when replacing such a wiring device, a certain level of skill or more is required since it involves reconnecting the wires to the wiring device, and furthermore, depending on the country or region, specific qualifications are required. Therefore, in general wiring devices, it may take time and effort to replace them. The wiring device system 10 according to the present embodiment aims to reduce the effort involved in replacing wiring devices, etc. by employing the following configuration.

The wiring device system 10 according to this embodiment includes a first unit 1 and a second unit 2. The first unit 1 is fixed to the construction target 3. The second unit 2 is removably attached to the first unit 1. The first unit 1 includes a power receiving section 11 (see FIG. 3) and a mounting space 12 (see FIG. 1A). The power receiving unit 11 receives power supply. The mounting space 12 is a space for mounting one second unit 2. The second unit 2 is a wiring device having a functional section 21 (see FIG. 4). The functional unit 21 performs at least one of supplying power to the load 4 and controlling the load 4 . The first unit 1 supplies power to the second unit 2.

That is, by employing the above configuration, the wiring device system 10 can reduce the effort involved in replacing wiring devices. In short, the second unit 2 as a wiring device is removably attached to the first unit 1 fixed to the construction target 3, so by removing the second unit 2 from the first unit 1, It is possible to remove only the two units 2 from the construction object 3. At this time, the first unit 1 equipped with the power receiving part 11 for receiving power supply remains on the workpiece 3 side, so the wiring 51 (see FIG. 2B) to the power receiving part 11 can be connected without being reconnected. It becomes possible to replace the second unit 2 as an instrument. Therefore, according to the wiring device system 10, it is possible to reduce the effort involved in replacing wiring devices, etc.

Further, the unit device according to the present embodiment is a device used as the first unit 1 or the second unit 2 in the wiring device system 10. In other words, the first unit 1 and the second unit 2 are each constituted by a unit device. Therefore, when looking at the wiring equipment system 10 as a whole, the unit device as the second unit 2 is removably attached to the unit device as the first unit 1.

(2) Details Below, the configuration of the wiring device system 10 according to the present embodiment will be described in detail with reference to FIGS. 1A to 4.

A case will be explained below. That is, in this embodiment, the wiring device system 10 functions as an outlet to which a plug of an electrical device as the load 4 is connected and supplies power to the load 4.

Further, in this embodiment, as an example, a case will be described in which the wiring device system 10 is fixed to a wall of a residential facility. In other words, the construction target 3 is a wall of a residential facility.

Hereinafter, when the wiring equipment system 10 is fixed to the wall of a residential facility, which is the construction target 3, the direction perpendicular (orthogonal) to the horizontal plane will be referred to as the "vertical direction", and the wiring equipment system 10 will be viewed from the front. The downward direction (vertical direction) when viewed is sometimes described as "downward." Also, the direction perpendicular to the up-down direction and parallel to the surface of the construction target 3 is referred to as the "left-right direction", and the right side when looking at the wiring device system 10 from the front is the "right side", and the left side is the "left side". It may be explained as. Furthermore, the direction perpendicular to both the vertical direction and the left-right direction, that is, the direction perpendicular to the surface of the construction object 3 is referred to as the "front-back direction," and the back side of the construction object 3 (back side of the wall) is referred to as the "rear". There are cases where However, these directions are not intended to limit the directions in which the wiring device system 10 is used.

Furthermore, "orthogonal" as used in the present disclosure includes not only a state in which they intersect strictly at 90 degrees, but also a state in which they intersect substantially at right angles within a certain degree of error. That is, the angle between the surface of the construction target 3 and the front-rear direction is within a certain error range (for example, 10 degrees or less) with respect to 90 degrees. In this embodiment, as an example, the angle between the surface of the construction target 3 and the front-rear direction is 90 degrees. Similarly, "parallel" in the present disclosure includes not only a state in which the angle between the two is strictly 0 degrees, but also a state in which the two are substantially parallel within a certain degree of error.

(2.2) Overall Configuration The wiring device system 10 includes a first unit 1 and a second unit 2, as shown in FIGS. 1A to 2B. The first unit 1 is fixed to a construction target 3 (in this embodiment, a wall of a residential facility). The second unit 2 is removably attached to the first unit 1.

FIG. 1A is a schematic perspective view of the second unit 2 removed from the first unit 1, and FIG. 1B is a schematic perspective view of the second unit 2 attached to the first unit 1. . Further, in FIGS. 2A and 2B, the second unit 2 attached to the first unit 1 is shown by an imaginary line (two-dot chain line).

The construction target 3 includes a wall panel 31 and a pillar 32 located on the back (rear) side of the wall panel 31. The wall panel 31 is fixed to the pillar 32. The construction target 3 has a construction hole 33 at a position corresponding to the first unit 1. The construction hole 33 penetrates the wall panel 31 in the thickness direction (front-back direction). In this embodiment, as an example, the construction hole 33 is formed in a circular (perfect circle) shape when viewed from the front.

The first unit 1 is arranged on the back side of the wall panel 31. The first unit 1 is fixed to the construction target 3 by being attached to the pillar 32 using a fixture 34 (see FIG. 1A) such as a wood screw, for example. The first unit 1 arranged on the back side of the wall panel 31 is exposed to the front of the wall panel 31 through the construction hole 33. That is, the first unit 1 can be accessed from the front side of the wall panel 31 by passing through the construction hole 33.

The first unit 1 includes a power receiving section 11 and a mounting space 12. The power receiving unit 11 receives power supply. The mounting space 12 is a space for mounting one second unit 2. A wiring 51 (see FIG. 2B) is electrically connected to the power receiving unit 11. The wiring 51 is electrically connected to a power source such as a system power source or a distributed power source, for example, via electrical equipment such as a distribution board 53 (see FIG. 8D). Thereby, the power receiving unit 11 receives power supply from the power source via the wiring 51.

Furthermore, the mounting space 12 for the first unit 1 has a recess 121 (see FIG. 1A) that accommodates at least a portion of the second unit 2. Here, the recess 121 is open to the front by forming a part of the front surface of the first unit 1 in a shape concave toward the rear. The recess 121 is included in the mounting space 12 for mounting the second unit 2. In this embodiment, as an example, as shown in FIG. 2A, the recess 121 is formed in a circular shape that is one size smaller than the construction hole 33 when viewed from the front. As a result, when the second unit 2 is mounted in the mounting space 12 of the first unit 1, at least a portion of the second unit 2 is accommodated in the recess 121 of the mounting space 12. In this embodiment, since the recess 121 is open to the front, at least the rear part of the second unit 2 is accommodated in the recess 121.

Further, the first unit 1 includes a switch box 13. The switch box 13 is fixed to the construction target 3. Furthermore, the switch box 13 has a lead-in part 131 (see FIG. 3) into which the wiring 51 is drawn. In this embodiment, the first unit 1 has a box-shaped switch box 13 as its outer shell, and has the power receiving section 11 and the like inside the switch box 13. The first unit 1 is fixed to the construction target 3 by attaching the switch box 13 to a pillar 32 with a fixture 34 such as a wood screw. Then, the wiring 51 is drawn into the switch box 13 from the lead-in part 131, so that the wiring 51 can be electrically connected to the power receiving part 11 within the switch box 13. In this embodiment, the first unit 1 is arranged on the back side of the wall panel 31, so the switch box 13 is a built-in switch box.

The second unit 2 is removably attached to the first unit 1. In other words, the second unit 2 is detachable from the first unit 1. In this embodiment, the second unit 2 is attached to the first unit 1 from the front side of the wall panel 31 through the construction hole 33 . The second unit 2 is configured to be supplied with power from the first unit 1 while attached to the first unit 1. That is, the first unit 1 supplies power to the second unit 2.

In the present embodiment, the second unit 2 includes a circular portion 22 that is circular when viewed from the front. The circular portion 22 is formed into a columnar shape. Further, the second unit 2 is integrated with the front end portion of the circular portion 22 and includes a front plate portion 23 having a square shape when viewed from the front. The front plate part 23 is formed one size larger than the front surface of the circular part 22 so that the front plate part 23 protrudes laterally (upwardly, downwardly, leftwardly, and rightwardly) from the entire circumference of the circular part 22. There is. In other words, the circular portion 22 is located within the projection plane of the front plate portion 23, and the cylindrical circular portion 22 protrudes rearward from the center of the back surface of the plate-shaped front plate portion 23. Become.

The second unit 2 is a wiring device having a functional section 21 (see FIG. 4). The functional unit 21 performs at least one of supplying power to the load 4 and controlling the load 4 . In this embodiment, the second unit 2 has a function as an outlet to which a plug of the load 4 can be connected. Therefore, the functional unit 21 is an outlet block that supplies power to the load 4. The load 4 has a pair of insertion pieces 41 on its plug. The "insertion piece" in the present disclosure means a conductive member that is inserted into the outlet (second unit 2) of the plug, and is, for example, a plug blade or a pin. In this embodiment, each of the pair of insertion pieces 41 is a plug blade made of a flat metal plate. The pair of insertion pieces 41 are arranged so as to face each other in the thickness direction of each insertion piece 41.

In the present embodiment, the second unit 2 functions as a 100V AC outlet without a ground electrode, and has a single-port type outlet to which one plug can be connected. Specifically, the second unit 2 has a pair of insertion holes 231 in the front plate portion 23. A pair of insertion holes 231 are provided so as to open at the front surface of the second unit 2. The pair of insertion holes 231 are configured to allow insertion of the pair of insertion pieces 41 of the plug. The functional unit 21 supplies power to the load 4 and mechanically holds the plug in a state where the pair of insertion pieces 41 are inserted into the pair of insertion holes 231.

Here, when the second unit 2 is installed in the installation space 12, it is accompanied by linear movement relative to the first unit 1. That is, when attaching the second unit 2 to the first unit 1, as shown in FIG. 1A, at least linear movement of the second unit 2 with respect to the first unit 1 is involved. Furthermore, when the second unit 2 is installed in the installation space 12, it is rotated relative to the first unit 1. That is, when the second unit 2 is attached to the first unit 1, at least the second unit 2 is rotated relative to the first unit 1, as shown in FIG. 1B. More specifically, after the second unit 2 is inserted straight into the first unit 1 in the direction of arrow A1 (see FIG. 1A), the second unit 2 is inserted straight into the first unit 1 in the direction of arrow A2 (see FIG. 1B). It is attached to the first unit 1 by being rotated. Here, the second unit 2 is rotated in opposite directions when the second unit 2 is attached and when it is removed. In this embodiment, as an example, when the second unit 2 is attached to the first unit 1, the second unit 2 rotates clockwise when viewed from the front, and when the second unit 2 is removed from the first unit 1, the second unit 2 rotates clockwise. rotates counterclockwise when viewed from the front.

In this embodiment, the first unit 1 employs a hook ceiling rosette as a structure for electrically and mechanically connecting the second unit 2. Specifically, the first unit 1 uses a rectangular hanging ceiling rosette (see FIG. 3) as the power receiving section 11. As a result, the pair of connection terminals 24 (see FIG. 4) in the second unit 2 are inserted into the power receiving section 11 from the front and further rotated clockwise in front view, so that the second unit 2 is connected to the second unit 2. It is electrically and mechanically connected to the power receiving section 11 of one unit 1 .

As explained above, the wiring device system 10 according to the present embodiment is divided into two units, the first unit 1 and the second unit 2. Therefore, by fixing the first unit 1 to the workpiece 3 and attaching the second unit 2 to the first unit 1, the entire wiring fixture system 10 is attached to the workpiece 3. Then, when the entire wiring device system 10 is attached to the construction target 3, as shown in FIGS. 2A and 2B, not only the first unit 1 but also the circular part 22 of the second unit 2 can be It is embedded in the construction target 3 through the hole 33. At this time, the front plate portion 23 of the second unit 2 covers the construction hole 33 from the front, so that the construction hole 33 is closed.

Further, with the entire wiring device system 10 attached to the construction target 3, the front surface of the first unit 1 comes into contact with the vicinity of the construction hole 33 in the wall panel 31 from behind. Furthermore, the back surface (rear surface) of the front plate portion 23 of the second unit 2 contacts the periphery of the construction hole 33 in the wall panel 31 from the front. Therefore, the wiring equipment system 10 can be attached to the construction target 3 with the wall panel 31 sandwiched between a part of the first unit 1 and a part of the second unit 2 (front plate part 23). become. Furthermore, the amount of protrusion from the surface of the wall panel 31 of the wiring device system 10 is approximately equal to the thickness dimension of the front plate portion 23.

(2.3) Configuration of first unit Next, the configuration of the first unit 1 will be described in more detail with reference to FIG. 3.

As shown in FIG. 3, the first unit 1 includes a power receiving section 11, a switch box 13, an inner cover 14, and an insertion guide 15. That is, in this embodiment, the first unit 1 further includes an inner cover 14 and an insertion guide 15 in addition to the above-described power receiving section 11, mounting space 12, and switch box 13.

As described above, the power receiving unit 11 is a rectangular hook ceiling rosette. In this embodiment, as an example, the power receiving unit 11 is formed in a rectangular parallelepiped shape that is longer in the left-right direction than in the up-down direction when viewed from the front. The power receiving unit 11 has a terminal on the back side for connecting the wiring 51 (see FIG. 2B).

Furthermore, the power receiving unit 11 has a pair of connection ports 111. The pair of connection ports 111 are located at both ends of the front surface of the power receiving unit 11 in the left and right direction. Each of the pair of connection ports 111 is formed in an arc shape along a virtual circle centered on the center point of the front surface of the power receiving unit 11 . Here, each of the pair of connection ports 111 has a wide portion at one end in the circumferential direction around the center point of the front surface of the power receiving section 11, which is wider than the other portion. Therefore, the pair of connection terminals 24 of the second unit 2 are inserted from the wide part into the pair of connection ports 111, and the second unit 2 is rotated clockwise when viewed from the front, so that the second unit 2 receives power. It is electrically and mechanically connected to section 11 . Thereby, the second unit 2 will be electrically connected to the wiring 51 via the power receiving section 11, and the first unit 1 will be able to supply power to the second unit 2.

In this embodiment, the power receiving unit 11 is fixed to the switch box 13 using a pair of bolts 161 and a pair of collars 162. The pair of bolts 161 and the pair of collars 162 are fastened to each other through the pair of through holes 112 of the power receiving section 11 and the pair of through holes 132 of the switch box 13, with the power receiving section 11 and the switch box 13 sandwiched therebetween. Strictly speaking, the pair of collars 162 are fixed to the power receiving unit 11 while being inserted into the pair of through holes 112 . The pair of through holes 112 penetrate the power receiving section 11 in the front-rear direction, and the pair of through holes 132 penetrate the bottom plate of the switch box 13 in the front-rear direction. Thereby, the power receiving unit 11 is fixed to the bottom plate of the switch box 13.

The switch box 13 is formed into a box shape with an open front. In this embodiment, as an example, the switch box 13 is made of metal and has a substantially square shape when viewed from the front. The switch box 13 has a hole as a recess 131 in the center of the bottom plate (rear wall) of the switch box 13 . Therefore, in the switch box 13, the wiring 51 can be drawn into the switch box 13 from the back (rear) side through the lead-in portion 131. The wiring 51 drawn into the switch box 13 is electrically connected to the power receiving unit 11 within the switch box 13 . A pair of through holes 132 are formed on both sides of the retracting portion 131 in the left-right direction in the bottom plate of the switch box 13 .

A pair of fixing holes 133 for fixing the switch box 13 to the construction target 3 are formed in the left side wall of the switch box 13 . That is, the switch box 13 is fixed to the construction object 3 by tightening the fixture 34 (see FIG. 1A) such as a wood screw to the pillar 32 of the construction object 3 through the pair of fixing holes 133. A pair of operating holes 134 are formed in the right side wall of the switch box 13 at positions facing the pair of fixing holes 133 . Thereby, the fixture 34 such as a wood screw can be operated through each operation hole 134 with a jig such as a screwdriver.

Inner cover 14 is housed within switch box 13 and functions as a cover for power receiving section 11 . In this embodiment, as an example, the inner cover 14 is made of resin and has a substantially square shape when viewed from the front. In a front view, the outer circumferential edge of the inner cover 14 substantially coincides with the inner circumferential edge of the peripheral wall of the switch box 13 . Therefore, when the inner cover 14 is housed in the switch box 13, the inner cover 14 fits into the switch box 13, and movement of the inner cover 14 with respect to the switch box 13 is restricted at least in the direction orthogonal to the front-rear direction. be done. Inner cover 14 is combined with switch box 13 so as to cover power receiving section 11 from the front. Thereby, the power receiving unit 11 is housed between the bottom plate of the switch box 13 and the inner cover 14.

In this embodiment, a recess is formed on the back (rear) side of the inner cover 14, and the power receiving unit 11 is accommodated in this recess. That is, the inner cover 14 and the power receiving section 11 are combined so that at least a portion of the power receiving section 11 enters into the inner cover 14 from the back surface of the inner cover 14. This allows the inner cover 14 to be placed near the bottom plate of the switch box 13. In this embodiment, the inner cover 14 is disposed closer to the bottom plate (that is, on the rear side) than the center in the front-rear direction in the internal space of the switch box 13 .

Here, a recess 141 is formed in the inner cover 14. The recess 141 is open to the front by forming a part of the front surface of the inner cover 14 in a shape concave toward the rear. In this embodiment, as an example, the depression 141 is formed in a circular shape that is one size smaller than the construction hole 33 when viewed from the front (see FIG. 2A). The inner diameter of the recess 141 is greater than or equal to the outer diameter of the circular portion 22 in the second unit 2, and is actually substantially the same as the outer diameter of the circular portion 22.

Furthermore, the inner cover 14 has a pair of insertion holes 142 formed in positions and shapes corresponding to the pair of connection ports 111 of the power receiving section 11 . The pair of insertion holes 142 are open at the bottom of the recess 141 and penetrate the inner cover 14 in the thickness direction (front-back direction). Specifically, the pair of insertion holes 142 are formed in the same position and shape as the pair of connection ports 111 of the power receiving unit 11 so as to overlap with the pair of connection ports 111 in the front view. Therefore, when mounting the second unit 2 in the mounting space 12, the pair of connection terminals 24 of the second unit 2 are inserted into the pair of connection ports 111 through the pair of insertion holes 142. Then, with the pair of connection terminals 24 inserted into the pair of connection ports 111 through the pair of insertion holes 142, the second unit 2 is rotated clockwise when viewed from the front, so that the second unit 2 becomes the power receiving section. 11 electrically and mechanically.

The insertion guide 15 is attached to the front end of the switch box 13 and functions as a guide for regulating the moving direction of the second unit 2 when the second unit 2 is attached to (or removed from) the first unit 1. . In this embodiment, as an example, the insertion guide 15 is made of resin and has a substantially square shape when viewed from the front. Except for the front end of the insertion guide 15, the outer peripheral edge of the insertion guide 15 substantially coincides with the inner peripheral edge of the peripheral wall of the switch box 13 when viewed from the front. Furthermore, the front end of the insertion guide 15 is formed to be slightly larger than the opening surface of the switch box 13 when viewed from the front. Therefore, the insertion guide 15 is attached to the front end of the switch box 13 so as to be fitted from the front, and movement of the insertion guide 15 with respect to the switch box 13 is restricted at least in a direction orthogonal to the front-rear direction.

Here, the insertion guide 15 is formed with a guide hole 151 that penetrates the insertion guide 15 in the thickness direction (front-back direction). Here, the guide hole 151 is formed in most of the insertion guide 15, leaving only the outer periphery of the insertion guide 15 when viewed from the front, so that the insertion guide 15 forms a frame.

In this embodiment, as an example, the guide hole 151 is formed at the same position as the depression 141 so as to overlap with the depression 141 when viewed from the front. Furthermore, when viewed from the front, the guide hole 151 has the same circular shape as the depression 141, but is formed in a shape that is enlarged only in a part of the circumference compared to the depression 141 (see FIG. 2A). . The inner diameter (minimum inner diameter) of the guide hole 151 is the same as the inner diameter of the recess 141. That is, the inner diameter (minimum inner diameter) of the guide hole 151 is greater than or equal to the outer diameter of the circular portion 22 in the second unit 2, and is actually substantially the same as the outer diameter of the circular portion 22. Therefore, the inner circumferential surface of the guide hole 151 overlaps with the inner circumferential surface of the recess 141 at a plurality of locations (eight locations in the example of FIG. 2A) when viewed from the front.

The first unit 1 is configured by combining the power receiving section 11, the switch box 13, the inner cover 14, and the insertion guide 15 configured as described above. When the second unit 2 is attached to the first unit 1, the circular portion 22 of the second unit 2 is inserted into the recess 141 of the inner cover 14 through the guide hole 151 of the insertion guide 15. Become. Therefore, the guide hole 151 of the insertion guide 15 and the recess 141 of the inner cover 14 each constitute a part of the recess 121 (see FIG. 1A) in which the second unit 2 is accommodated. Therefore, the guide hole 151 of the insertion guide 15 and the recess 141 of the inner cover 14 are included in the mounting space 12. The bottom surface of the depression 141 constitutes the bottom surface of the recess 121 formed in the mounting space 12.

Then, the inner circumferential surface of the guide hole 151 in the insertion guide 15 and the inner circumferential surface of the recess 141 in the inner cover 14 contact the outer circumferential surface of the circular part 22 of the second unit 2, so that the insertion guide 15 and the inner cover 14 regulates the moving direction of the second unit 2. In other words, the insertion guide 15 and the inner cover 14 restrict movement of the second unit 2 relative to the first unit 1 in a direction orthogonal to the front-rear direction.

Therefore, when the second unit 2 is inserted into and removed from the mounting space 12 (recess 121), the insertion guide 15 and the inner cover 14 function as guides, and movement of the second unit 2 in directions other than the front-back direction is restricted. . As a result, mounting (or removal) of the second unit 2, which involves moving the second unit 2 in the front-rear direction, becomes relatively easy. Also, when rotating the second unit 2 relative to the first unit 1, the insertion guide 15 and the inner cover 14 function as guides, and the movement of the second unit 2 other than the rotation of the second unit 2 is limited. As a result, attachment (or removal) of the second unit 2, which involves rotation of the second unit 2, becomes relatively easy.

(2.4) Configuration of second unit Next, the configuration of the second unit 2 will be described in more detail with reference to FIG. 4.

As shown in FIG. 4, the second unit 2 includes a functional section 21, a circular section 22, a front plate section 23, a pair of connection terminals 24, and a mounting cover 27. That is, in this embodiment, the second unit 2 further includes a mounting cover 27 in addition to the above-described functional section 21, circular section 22, front plate section 23, and pair of connection terminals 24.

Specifically, the functional section 21 is formed into a rectangular parallelepiped shape that is longer in the left-right direction than in the up-down direction when viewed from the front. The functional part 21 has a terminal for connecting an electric wire on the back side. Electric wires connected to a pair of connection terminals 24 are connected to the terminals of the functional section 21 .

Furthermore, the functional section 21 has a pair of insertion ports 211 . The pair of insertion ports 211 are arranged so as to face each other in the left-right direction on the front surface of the functional section 21 . The pair of insertion ports 211 are configured to allow insertion of the pair of insertion pieces 41 of the plug of the load 4 . The functional unit 21 supplies power to the load 4 and mechanically holds the plug in a state where the pair of insertion pieces 41 are inserted into the pair of insertion ports 211.

More specifically, the functional unit 21 has a case 212 made of resin such as urea resin or ASA (Acrylate Styrene Acrylonitrile), and a pair of insertion ports 211 are formed on the front surface of this case 212. . The functional unit 21 has a pair of conductive members at positions corresponding to the pair of insertion ports 211 inside the case 212 . Each conductive member is made of a metal plate having conductivity and elasticity, for example, a metal plate of copper or copper alloy. The conductive member mechanically holds the insertion piece 41 inserted into the insertion opening 211 and is electrically connected to the insertion piece 41 . In this embodiment, since the insertion piece 41 is a plug blade, the conductive member is a blade receiving member that holds the insertion piece 41 on both sides.

Furthermore, the functional section 21 further includes a plurality of attachment pieces 213 that protrude from both end surfaces of the case 212 in the left-right direction. These plurality of attachment pieces 213 are used when fixing the functional section 21 to the attachment frame of a large rectangular interconnection wiring device standardized by the Japanese Industrial Standards. In this embodiment, the functional part 21 is fixed to the circular part 22 by using the plurality of attachment pieces 213.

The circular portion 22 includes a hollow portion 25 and a lid body 26. The hollow portion 25 is formed in a cylindrical shape that is circular in a front view. The lid body 26 is formed into a disk shape, which is circular when viewed from the front. The lid body 26 is coupled to the hollow portion 25 so as to close the back surface (rear surface) of the hollow portion 25. By combining the lid 26 with the hollow portion 25 in this manner, the circular portion 22 is configured. In this embodiment, as an example, the hollow portion 25 and the lid 26 that constitute the circular portion 22 are both made of resin.

The hollow part 25 has a pair of screw holes 251 for fixing the lid body 26 and the mounting cover 27 to the hollow part 25 . Specifically, the lid body 26 is coupled to the hollow portion 25 by a pair of screws 281 inserted into the pair of screw holes 251 from the rear. The mounting cover 27 is coupled to the hollow portion 25 by a pair of screws 282 inserted into the pair of screw holes 251 from the front.

Moreover, the hollow part 25 accommodates at least a part of the functional part 21 in its internal space. The hollow part 25 further includes a pair of fixing parts 252 for fixing the functional part 21. The pair of fixing parts 252 protrude from positions facing each other in the left-right direction on the inner circumferential surface of the hollow part 25 in a direction toward each other. Each fixing portion 252 has a pair of fixing recesses 253 arranged in the vertical direction. Each fixing recess 253 is open to the front.

Further, the hollow portion 25 further includes a pair of through holes 254 for fixing the front plate portion 23. Each through hole 254 penetrates the hollow portion 25 in its thickness direction (radial direction). Specifically, the front plate portion 23 is coupled to the hollow portion 25 by a pair of screws 284 inserted into the pair of through holes 254 from the sides. At this time, the pair of screws 284 are tightened against a pair of projecting pieces that protrude rearward from the back surface (rear surface) of the front plate section 23.

The lid body 26 is attached to the rear end of the hollow portion 25 and closes the back surface (rear surface) of the hollow portion 25. Except for the rear end of the lid 26, the outer peripheral edge of the lid 26 substantially coincides with the inner peripheral edge of the hollow portion 25 when viewed from the front. Furthermore, the rear end portion of the lid body 26 is formed to be slightly larger than the opening surface of the hollow portion 25 when viewed from the front. Therefore, the lid 26 is attached to the rear end of the hollow portion 25 so as to be fitted from the rear, and movement of the lid 26 with respect to the hollow portion 25 at least in a direction orthogonal to the front-rear direction is restricted.

Here, a recess 261 is formed in the lid body 26. The depression 261 is opened to the front by forming a part of the front surface of the lid body 26 in a shape concave toward the rear. In this embodiment, as an example, the recess 261 is formed to be one size larger than the rear end of the functional section 21 so as to accommodate the rear end of the functional section 21 .

Further, the lid body 26 further includes a pair of through holes 262 through which the pair of screws 281 described above are passed. That is, the lid body 26 is coupled to the hollow portion 25 by tightening the pair of screws 281 into the pair of screw holes 251 through the pair of through holes 262 .

Furthermore, a pair of connection terminals 24 are fixed to the back surface (rear surface) of the lid body 26. The pair of connection terminals 24 are arranged at both ends in the left and right direction on the back surface of the lid 26 and are fixed to the lid 26 with a pair of screws 283 . Each connection terminal 24 is made of a conductive metal plate, for example, a metal plate made of copper or copper alloy. The pair of connection terminals 24 are each formed in such a shape that its rear end portions are bent inward, that is, in a direction toward each other. As a result, the second unit 2 is rotated clockwise when viewed from the front with the pair of connection terminals 24 inserted into the pair of connection ports 111 (see FIG. 3), so that the pair of connection terminals 24 are inserted into the pair of connection ports 111 (see FIG. 3). It is caught on the power receiving section 11 and is electrically and mechanically connected to the power receiving section 11 .

The front plate part 23 has a pair of insertion holes 231 formed in positions and shapes corresponding to the pair of insertion holes 211 of the functional part 21 . The pair of insertion holes 231 are open at the center of the front surface of the front plate part 23 and penetrate the front plate part 23 in the thickness direction (front-back direction). Specifically, the pair of insertion holes 231 are formed in the same position and shape as the pair of insertion ports 211 so as to overlap with the pair of insertion ports 211 of the functional section 21 when viewed from the front. Therefore, when connecting the plug of the load 4 to the functional part 21, the pair of insertion pieces 41 of the plug are inserted into the insertion port 211 through the pair of insertion holes 231. Then, with the pair of insertion pieces 41 inserted into the pair of insertion ports 211 through the pair of insertion holes 231, the load 4 is electrically and mechanically connected to the functional part 21. Become.

The mounting cover 27 is attached to the front end of the hollow portion 25 and has a function of fixing the functional portion 21 to the hollow portion 25 (circular portion 22). In this embodiment, as an example, the mounting cover 27 is made of metal and has a substantially circular shape when viewed from the front. In a front view, the outer circumferential edge of the mounting cover 27 substantially coincides with the inner circumferential edge of the hollow portion 25 . Therefore, the mounting cover 27 is attached so as to be fitted into the front end of the hollow portion 25 from the front, and movement of the mounting cover 27 with respect to the hollow portion 25 is restricted at least in a direction orthogonal to the front-rear direction.

Here, the mounting cover 27 is formed with a mounting hole 271 that penetrates the mounting cover 27 in the thickness direction (front-back direction). Here, the mounting holes 271 are formed in most of the mounting cover 27, leaving only the outer peripheral portion of the mounting cover 27 when viewed from the front, so that the mounting cover 27 forms a frame.

In this embodiment, as an example, the inner circumferential edge of the attachment hole 271 substantially matches the outer circumferential edge of the front end portion of the functional part 21 when viewed from the front. Therefore, when the mounting cover 27 and the functional section 21 are combined, the front end of the functional section 21 projects forward from the front surface of the mounting cover 27 through the mounting hole 271 of the mounting cover 27.

Furthermore, the mounting cover 27 further includes a pair of through holes 272 through which the pair of screws 282 described above are passed. That is, the mounting cover 27 is coupled to the hollow portion 25 by tightening the pair of screws 282 into the pair of screw holes 251 through the pair of through holes 272 .

When the mounting cover 27 is coupled to the hollow part 25, the mounting cover 27 fixes the functional part 21 to the hollow part 25 (circular part 22). In the present embodiment, as an example, the mounting cover 27 is constructed by sandwiching at least a part of the functional section 21 (here, the mounting piece 213) between a pair of fixing parts 252 in the hollow part 25 (circular shape). The functional part 21 is fixed to the part 22). Specifically, with each mounting piece 213 of the functional part 21 fitted into each fixing recess 253 of the fixed part 252, the mounting cover 27 presses down each mounting piece 213 of the functional part 21 from the front, so that the mounting cover 27 holds each mounting piece 213 in each fixing recess 253. Thereby, the functional part 21 is fixed to the hollow part 25 (circular part 22).

The second unit 2 is configured by combining the functional part 21, circular part 22 (hollow part 25 and lid 26), front plate part 23, pair of connection terminals 24, and mounting cover 27 configured as described above. be done.

(3) Example of replacing the second unit Next, an example of replacing the second unit 2 in the wiring device system 10 according to the present embodiment will be described with reference to FIG. 5. FIG. 5 is an explanatory diagram schematically showing an example of replacement of the second unit 2. For example, the shape of the first unit 1 exposed from the construction hole 33 is appropriately simplified and illustrated.

In this embodiment, a plurality of types of second units 201 to 207 can be attached to the first unit 1. When the plurality of types of second units 201 to 207 are not particularly distinguished, each of the plurality of types of second units 201 to 207 is simply referred to as "second unit 2." That is, in the wiring device system 10 according to the present embodiment, the entire wiring device system 10 is attached to the construction target 3 when the second unit 2 is attached to the first unit 1. Therefore, in the wiring device system 10 according to the present embodiment, it is possible to replace only the second unit 2 with another second unit 2 while leaving the first unit 1 fixed to the construction target 3. . As a result, in the wiring device system 10, for example, the second units 202 to 207 can be attached to the first unit 1 in place of the second unit 201 having a function as an outlet as described above. function can be replaced. As a result, the wiring device system 10 can realize wiring devices having various functions.

That is, as shown in FIG. 5, by lining up a plurality of types of second units 2, the wiring device system 10 can realize various wiring device functions. These plural types of second units 202 to 207 adopt the same configuration as the second unit 201 in terms of the configuration related to electrical and mechanical connection to the first unit 1. These plural types of second units 201 to 207 are formed to have the same shape and dimensions when viewed from the front. Therefore, each second unit 2 is attached to the first unit 1 by being inserted into the first unit 1 and then rotating clockwise relative to the first unit 1 when viewed from the front.

In the example of FIG. 5, the second unit 202 is a wiring device that includes a rotary operation type user interface such as a volume, a rotary encoder, or a rotary switch, and has a function as a load control device. The second unit 202 controls the load 4 by controlling the energization state of the load 4 such as a lighting fixture in accordance with the user's operation received by the user interface. The second unit 203 is a wiring device that functions as a USB (Universal Serial Bus) outlet. This second unit 203 has a USB receptacle into which a USB plug of the load 4 can be inserted and connected, and is configured to output a 5V DC voltage to the load 4 through the USB plug.

Further, the second unit 204 is a wiring device that functions as a magnetic outlet that attracts a plug using magnetic force. This second unit 204 is configured to supply alternating current or direct current power to the load 4 through the plug by attracting the plug of the load 4 with the magnetic force of a magnet. The second unit 205 is a wiring device that includes a human sensor or a sensor for brightness, and has a function as a load control device. The second unit 205 controls the load 4 by controlling the energization state of the load 4 such as a lighting fixture according to the detection result of the sensor.

Further, the second unit 206 is a wiring device that includes a push button type, seesaw type, or touch type user interface and has a function as a switch device. The second unit 206 controls the load 4 by controlling the energization state of the load 4 such as a lighting fixture in accordance with the user's operation received by the user interface. In particular, the second unit 206 includes a plurality of user interfaces (here, four), and has a plurality of (here, four) switches as the functional section 21. Therefore, it is possible to control a plurality of (four in this case) loads 4 with one second unit 206. Further, the second unit 207 is a wiring device that includes a push button type, seesaw type, or touch type user interface and has a function as a switch device. The second unit 207 controls the load 4 by controlling the energization state of the load 4 such as a lighting fixture in accordance with the user's operation received by the user interface.

In short, in the wiring device system 10 according to the present embodiment, the second unit 2 as a wiring device is removably attached to the first unit 1 fixed to the construction target 3. Therefore, by removing the second unit 2 from the first unit 1, it is possible to remove only the second unit 2 from the construction target 3. At this time, since the first unit 1 equipped with the power receiving part 11 for receiving power supply remains on the construction target 3 side, the second unit 1 as a wiring device can be used without reconnecting the wiring to the power receiving part 11. 2 can be exchanged. Therefore, when a plurality of types of second units 2 are lined up as described above, by replacing the second units 2, it is possible to realize various wiring fixture functions in the wiring fixture system 10.

Furthermore, since the first unit 1 is shared by multiple types of second units 2, the first unit 1 can be reused even if the type of wiring equipment for the entire wiring equipment system 10 is changed. It is. Furthermore, not only when replacing an existing second unit 2 with another second unit 2, but also when installing a new second unit 2, various second units 2 such as those described above can be adopted. be.

By the way, in the wiring device system 10 according to the present embodiment, devices 601 and 602 that operate by receiving power supply from the first unit 1 can be installed in the installation space 12 instead of the second unit 2. In FIG. 5, multiple types (here, two types) of devices 601 and 602 are shown, but when the multiple types of devices 601 and 602 are not particularly distinguished, each of the multiple types of devices 601 and 602 is simply referred to as "equipment". 6". That is, in the wiring device system 10 according to the present embodiment, the entire wiring device system 10 is attached to the construction target 3 when the second unit 2 is attached to the first unit 1. Therefore, in the wiring device system 10 according to the present embodiment, it is possible to replace the second unit 2 with the device 6 while leaving the first unit 1 fixed to the construction target 3.

Here, regarding the equipment 6 as well, by lining up a plurality of types of equipment 601 and 602 as shown in FIG. 5, various functions of the equipment 6 can be realized by the wiring device system 10. These multiple types of devices 601 and 602 employ the same configuration as the second unit 201 for electrical and mechanical connection to the first unit 1. The plurality of types of devices 601 and 602 are formed so that the shape and dimensions when viewed from the front are the same as the second unit 2. Therefore, each device 6 is attached to the first unit 1 by being inserted into the first unit 1 and then rotated clockwise relative to the first unit 1 when viewed from the front.

In the example of FIG. 5, the device 601 has a function as a lighting device (including downlights, emergency lights, footlights, etc.) that outputs light. This device 601 receives power from the first unit 1 and turns on the light source, thereby illuminating the surrounding area. The device 602 has a function as a sound output device (including a speaker and an AI speaker) that outputs sound (including voice, beep sound, melody, etc.). This device 602 receives power from the first unit 1, converts an electrical signal into sound, and outputs sound.

However, the device 6 shown in FIG. 5 is only an example, and in addition to the lighting device and the sound output device, for example, a display, a communication device, a measuring device, etc. can be employed as the device 6.

(4) Modifications Embodiment 1 is just one of various embodiments of the present disclosure. Embodiment 1 can be modified in various ways depending on the design, etc., as long as the objective of the present disclosure can be achieved. Each of the figures described in this disclosure is a schematic diagram, and the ratio of the size and thickness of each component in each figure does not necessarily reflect the actual size ratio.

Modifications of the first embodiment will be listed below. The modified examples described below can be applied in combination as appropriate. Hereinafter, configurations similar to those in Embodiment 1 will be given the same reference numerals and descriptions will be omitted as appropriate.

(4.1) First Modification In a wiring device system 10A according to a first modification, the shape of the mounting space 12 is different from that of the wiring device system 10 of the first embodiment, as shown in FIGS. 6A to 6C. In FIGS. 6A to 6C, the second unit 2 is shown by an imaginary line (two-dot chain line). In FIGS. 6A to 6C, for example, the shape of the first unit 1 exposed from the construction hole 33 is illustrated in a simplified manner as appropriate.

In this modification, the first unit 1 has a structure for electrically and mechanically connecting the second unit 2 with a plug-in type, such as an I-type outlet, instead of a hanging ceiling rosette. A connector is used. Specifically, the first unit 1 has an insertion hole 142A forming an I-type outlet on its front surface. As a result, the plurality of plug blades protruding rearward from the back surface (rear surface) of the second unit 2 are inserted into the insertion hole 142A from the front, so that the second unit 2 is connected to the power receiving section 11 of the first unit 1. electrically and mechanically connected to the Therefore, in this modification, when the second unit 2 is installed in the installation space 12, although the second unit 2 is moved linearly with respect to the first unit 1, the second unit 2 is moved relative to the first unit 1. No relative rotation is involved.

In this manner, when the second unit 2 does not rotate, the shape of the mounting space 12 is not limited to a rotationally symmetrical shape such as a circular shape, but any suitable shape can be adopted. In the example of FIG. 6A, the mounting space 12 is formed in a square shape when viewed from the front. In this case, also in the second unit 2, instead of the circular portion 22, a configuration having a square shape when viewed from the front is adopted. In the example of FIG. 6B, the mounting space 12 is formed in a substantially triangular shape when viewed from the front. In this case, also in the second unit 2, instead of the circular portion 22, a configuration having a substantially triangular shape when viewed from the front is adopted. Moreover, in the example of FIG. 6C, the mounting space 12 is formed in an elliptical shape when viewed from the front. In this case, also in the second unit 2, instead of the circular portion 22, a configuration having an elliptical shape when viewed from the front is adopted.

In this way, according to the first modification, when the second unit 2 is installed in the installation space 12, the second unit 2 is not rotated relative to the first unit 1. The direction is easy to determine.

(4.2) Second Modification In the wiring device system 10B according to the second modification, as shown in FIGS. 7A to 7C, the posture of the second unit 2 when installed in the installation space 12 is variable. be. In the present disclosure, "posture" refers to the orientation, position, etc. of the second unit 2 in a state fixed to the construction target 3. In FIG. 7A, the second unit 2 is shown by an imaginary line (two-dot chain line). In FIGS. 7A to 7C, for example, the shape of the first unit 1 exposed from the construction hole 33 is illustrated in a simplified manner as appropriate.

In this modification, the first unit 1 has a structure for electrically and mechanically connecting the second unit 2 with a plug-in type, such as a phone jack, instead of a hanging ceiling rosette. A connector is used. Specifically, the first unit 1 has an insertion hole 142B forming a two-pole phone jack in the center of its front surface. As a result, the phone plug protruding rearward from the back surface (rear surface) of the second unit 2 is inserted into the insertion hole 142B from the front, so that the second unit 2 connects to the power receiving section 11 of the first unit 1. electrically and mechanically connected. Therefore, in this modification, when the second unit 2 is installed in the installation space 12, although the second unit 2 is moved linearly with respect to the first unit 1, the second unit 2 is moved relative to the first unit 1. No relative rotation is involved.

Furthermore, in this modification, the insertion hole 142B is arranged at the center of the front surface of the first unit 1. According to such a configuration, when the phone plug is inserted into the insertion hole 142B (phone jack), the second unit 2 can be rotated relative to the first unit 1, as shown in FIGS. 7B and 7C. It is possible to do so. As an example, the posture of the second unit 2 changes by being rotated in the direction of arrow A3 (see FIG. 7C) with respect to the first unit 1. In the example of FIG. 7C, the second unit 2 is rotated 90 degrees clockwise when viewed from the front from the example of FIG. 7B, so that the pair of insertion holes 231 are aligned in the vertical direction.

In this way, according to the second modification, it is possible to change the attitude of the second unit 2 while the second unit 2 remains attached to the attachment space 12 of the first unit 1.

(4.3) Third Modification In a wiring device system 10C according to a third modification, the first unit 1 includes a mounting frame 74, as shown in FIG. 8A. The mounting frame 74 is, for example, a mounting frame for a large rectangular interconnection wiring device standardized by Japanese Industrial Standards. That is, in this modification, the wiring device system 10C is fixed to the construction object 3 using the mounting frame 74.

In the example of FIG. 8A, the switch box 13 of the first unit 1 is fixed to the mounting frame 74. Furthermore, a decorative frame 75 can be attached to the attachment frame 74 directly or indirectly. Thereby, the periphery of the second unit 2 can be covered with the decorative frame 75 in a state where the wiring device system 10C is fixed to the construction target 3, and the appearance is improved.

(4.4) Fourth Modification In a wiring device system 10D according to a fourth modification, the first unit 1 and the second unit 2 are electrically connected by a cable 71, as shown in FIG. 8B. There is. A connector 72 is provided at one end of the cable 71. An end of the cable 71 opposite to the connector 72 is connected to the second unit 2 . Therefore, by connecting the connector 72 to the first unit 1, the first unit 1 and the second unit 2 are electrically connected via the cable 71. In this modification, the electrical connection and mechanical connection (coupling) between the first unit 1 and the second unit 2 are realized by different means.

Further, in this modification, at least one of the first unit 1 and the second unit 2 includes a power conversion section 73. The power conversion unit 73 converts power. That is, in the wiring device system 10D, the power conversion section 73 provided in the first unit 1 and/or the second unit 2 converts power. "Conversion of power" in the present disclosure includes, for example, conversion from AC power to DC power, conversion from DC power to AC power, voltage conversion, and the like. The power conversion unit 73 is realized by a circuit that performs these conversions. In this modification, as an example, the power conversion unit 73 is an AC-DC converter that converts 100V AC power to, for example, 5V, 12V, 24V, or 48V DC power.

In particular, in this modification, the power conversion section 73 is provided in the first unit 1. That is, the power conversion section 73 is housed within the switch box 13 of the first unit 1. A wiring 51 drawn into the first unit 1 is connected to the power converter 73 .

In the wiring device system 10J according to the present embodiment, it is possible to mechanically hold the second unit 2 by using such an unused connection portion 18. That is, in the present embodiment, some of the plurality of connection sections 18 for power feeding feed power to the second unit 2 mounted in the mounting space 12 . One or more of the plurality of connection parts 18 other than the power supply connection part 18 mechanically holds the second unit 2 mounted in the mounting space 12 .

As an example, as shown in FIG. 12C, it is assumed that the second unit 2 using the second connection part 18 as the power supply connection part 18 is attached to the first unit 1. In this case, the connection terminal 24 of the second unit 2 is inserted into the second connection part 18 (three second connection ports 182) for power supply among the plurality of connection parts 18. On the other hand, the connection parts 18 other than the power supply connection part 18, that is, the first connection part 18 (a pair of first connection ports 181) are used for mechanically holding the second unit 2. Specifically, the second unit 2 has a dummy terminal 29 in addition to the connection terminal 24, and this dummy terminal 29 is inserted into the first connection portion 18 (a pair of first connection ports 181). Since the dummy terminal 29 is simply used for mechanically holding the second unit 2, it is electrically separated from the functional section 21 of the second unit 2, like the connection terminal 24. Dummy terminal 29 may be made of electrically insulating material.

In this way, by mechanically holding the second unit 2 using the connection part 18 that is not used for power supply, it is possible to improve the strength of the holding of the second unit 2 by the first unit 1. .

Further, depending on the second unit 2, a plurality of connection parts 18 may be used for power supply.

The configuration described in Embodiment 5 (including modified examples) can be employed in appropriate combination with the various configurations (including modified examples) described in Embodiments 1 to 4.
