[0008] A wiring duct fixture F1 and a duct system 100 including the wiring duct fixture F1 according to an embodiment of the present disclosure will be described in detail with reference to the drawings. Note that the figures described in the following embodiments are schematic diagrams, and the size and thickness ratios of the components in the figures do not necessarily reflect the actual dimensional ratios. Furthermore, the embodiments and modifications described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiments and modifications. Various modifications other than these embodiments and modifications are possible depending on the design, etc., as long as they do not deviate from the technical concept of the present disclosure. Furthermore, the following embodiments (including modifications) may be realized in appropriate combinations.

[0009] (1) Overview First, an overview of the wiring duct fixture F1 according to this embodiment will be described with reference to FIGS. 1 to 3 and 10. FIG.

[0010] The wiring duct fixture F1 of this embodiment is used to fix a wiring duct 4 (so-called DC duct) that supplies DC power to an electric device 20 (see FIG. 10) to a fixture.

[0011] As shown in FIGS. 1 to 3, the wiring duct fixture F1 includes a first fixing portion 1, a second fixing portion 2, and a connector holding portion 7. The first fixing portion 1 is long and has a wiring duct 4 attached thereto. The second fixing portion 2 is provided at least at one end of the first fixing portion 1 in the longitudinal direction and fixes the first fixing portion 1 to a flat top plate 31. The connector holding portion 7 is provided on the second fixing portion 2 and holds a connector portion 8 that electrically connects a first connection line W1 connected to the wiring duct 4 and a second connection line W2 connected to a power source 5 (see FIG. 10).

[0012] In this embodiment, the desk 3, which is a fixture, is provided with a top panel 31. Here, fixture is a general term for furniture, fixtures, and other equipment used in residential or non-residential settings. Note that the fixture provided with the top panel 31 is not limited to the desk 3, and may be a table or workbench used as a platform for placing items.

[0013] According to the above configuration, the connector portion 8 is held by the connector holding portion 7 provided on the second fixing portion 2, so that the area in which the first connection line W1 and the second connection line W2 connected to the connector portion 8 can be wired is limited to the periphery of the second fixing portion 2. This makes it difficult for the first connection line W1 and the second connection line W2 to be wired on the top plate 31, and reduces the possibility that the convenience of the furniture (desk 3) equipped with the top plate 31 will be reduced.

[0014] (2)Details The duct system 100 including the wiring duct fixture F1 will be described in detail below. In the following description, in Figures 1 to 3 and 5 to 7, the direction along one side of the square-shaped top plate 31 is defined as the left-right direction, the horizontal direction perpendicular to the left-right direction is defined as the front-rear direction, and the thickness direction of the top plate 31 is defined as the up-down direction. However, these definitions are not intended to limit the direction in which the duct system 100 is used. Furthermore, the arrows representing the front-rear, left-right, and up-down directions in Figures 1 to 3 and 5 to 7 are merely shown for the purpose of explanation and do not have any substance.

[0015] As shown in Figures 1 and 2, the duct system 100 comprises a wiring duct fixing fixture F1, two wiring ducts 4 (only one is shown in Figures 1 and 2), two feed-ins 6 (only one is shown in Figures 1 and 2) for supplying power from a power source 5 (see Figure 10) to each of the two wiring ducts 4, two end caps CP1 (only one is shown in Figures 1 and 2), and a partition section 10.

[0016] The duct system 100 fixes the wiring duct 4 to the top board 31 of the desk 3 via a wiring duct fixture F1. The wiring duct 4 supplies power to electrical equipment 20 (see FIG. 10 ) used by a worker on the top board 31. The type of electrical equipment 20 is not particularly limited. Examples of the electrical equipment 20 include computer terminals (personal computers, smartphones, tablet terminals, etc.), accessories for computer terminals (monitors, speakers, microphones, etc.), lighting equipment (desk lamps, etc.), network cameras, sensors (temperature sensors, humidity sensors, illuminance sensors, etc.), game consoles, and air conditioning equipment (desk fans, etc.).

[0017] As shown in FIG. 1 , the desk 3 has a top panel 31 that is square in plan view, two legs 32, and two support bases 33. One of the two legs 32 protrudes downward from near the right end of the top panel 31, and the other of the two legs 32 protrudes downward from near the left end of the top panel 31. The two support bases 33 correspond one-to-one to the two legs 32. Each support base 33 is connected to the lower end of the corresponding leg 32 and supports the leg 32.

[0018] (2.1) Wiring duct fixing device The wiring duct fixture F1 includes the first fixing portion 1 and the second fixing portion 2, as described above.

[0019] As shown in FIGS. 1 and 2, the first fixing part 1 has an elongated shape that is long in the left-right direction. Furthermore, as shown in FIG. 4, grooves 11 and 12 are formed on the front and rear surfaces of the first fixing part 1 along the left-right direction. Groove 11 opens forward on the front surface of the first fixing part 1, and groove 12 opens rearward on the rear surface of the first fixing part 1. In this embodiment, groove 11 accommodates one wiring duct 4 (first wiring duct 41), and groove 12 accommodates one wiring duct 4 (second wiring duct 42). That is, two wiring ducts 4 (first wiring duct 41, second wiring duct 42) are attached to the first fixing part 1 facing each other in the front-rear direction. Each of grooves 11 and 12 may accommodate a plurality of wiring ducts 4.

[0020] 3 and 5, a feed-in 6 (feed-in 61) that supplies power to the first wiring duct 41 is accommodated in the right end of the groove 11, and an end cap CP1 is accommodated in the left end of the groove 11, as shown in FIGS. 1 and 2. Specifically, the first wiring duct 41, which has the end cap CP1 and the feed-in 61 accommodated at both ends in the left-right direction, is accommodated in the groove 11. The feed-in 6 (feed-in 62) that supplies power to the second wiring duct 42 is accommodated in the right end of the groove 12, and the end cap CP1 is accommodated in the left end of the groove 12. Specifically, the second wiring duct 42, which has the end cap CP1 and the feed-in 62 accommodated at both ends in the left-right direction, is accommodated in the groove 12. The feed-in 61 may be accommodated in the left end of the groove 11, in which case the end cap CP1 is accommodated in the right end of the groove 11. The feed-in 62 may also be housed at the left end of the groove 12, in which case the end cap CP1 is housed at the right end of the groove 12.

[0021] As shown in FIGS. 1 and 2, the second fixing portions 2 are provided at both ends of the first fixing portion 1 in the longitudinal direction. That is, the wiring duct fixing device F1 has two second fixing portions 2 (second fixing portions 21, 22). The second fixing portions 21, 22 fix the first fixing portion 1 to the top plate 31. That is, the second fixing portions 21, 22 fix the first wiring duct 41 and the second wiring duct 42 to the top plate 31. Of the second fixing portions 21, 22, the second fixing portion 21 provided at the right end of the first fixing portion 1 in the longitudinal direction will be described below. The second fixing portion 22 provided at the left end of the first fixing portion 1 in the longitudinal direction has a structure symmetrical to the second fixing portion 21 described below, and therefore will not be described in detail.

[0022] As shown in FIGS. 3, 5 and 6, the second fixing portion 21 has a stay portion 23 that protrudes from the right end of the first fixing portion 1 in the longitudinal direction toward the top board 31 side.

[0023] The stay portion 23 has a base portion 24 into which a part of the top plate 31 is inserted. In detail, as shown in Figures 3, 5 and 6, the stay portion 23 has a support portion 25 formed in a flat plate shape along the up-down direction, an insertion portion 26 formed in a flat plate shape that is provided continuous with the upper end of the support portion 25 and protrudes from the upper end of the support portion 25 towards the first fixed portion 1 side (left side), and the base portion 24 provided continuous with the lower end of the support portion 25.

[0024] The insertion portion 26 is inserted from the right side surface of the first fixed portion 1 into an attachment groove 13 provided along the left-right direction on the underside of the first fixed portion 1. With the insertion portion 26 inserted into the attachment groove 13, the second fixed portion 21 is fixed to the right end portion of the first fixed portion 1 by being fixed to the first fixed portion 1 from below with, for example, a screw.

[0025] 6, the base portion 24 has an upper surface portion 241 formed in a flat plate shape that protrudes from the lower end of the support portion 25 to the side opposite to the first fixed portion 1 (the right side), an abutting portion 242 formed in a flat plate shape that protrudes downward from the right end of the upper surface portion 241, and a lower surface portion 243 formed in a flat plate shape that protrudes to the left from the lower end of the abutting portion 242. In other words, the upper surface portion 241 and the lower surface portion 243 face each other in the vertical direction with the abutting portion 242 sandwiched therebetween. Furthermore, the upper surface portion 241, the abutting portion 242, and the lower surface portion 243 form a recess 27 that opens toward the left side.

[0026] The second fixing portion 21 further includes a clamp portion 28. As shown in FIG. 6 , the clamp portion 28 includes a support shaft 281 whose axial direction is the vertical direction, a contact surface portion 282 connected to the upper end of the support shaft 281, and a knob 283 fixed to the lower end of the support shaft 281. The contact surface portion 282 is connected to the support shaft 281 so as to be rotatable about its axis. The support shaft 281 is provided with, for example, a thread groove, and is screwed into a screw hole 244 formed in a lower surface portion 243 of the base portion 24. In other words, the contact surface portion 282 connected to the upper end of the support shaft 281 is located in the recess 27 of the base portion 24, and the contact surface portion 282 is configured to be movable in the vertical direction between the upper surface portion 241 and the lower surface portion 243 by rotating the knob 283.

[0027] Here, the right end of the tabletop 31 is inserted between the upper surface portion 241 and the contact surface portion 282 until it abuts against the abutment portion 242. In this state, by rotating the knob 283 to move the contact surface portion 282 upward, the tabletop 31 is sandwiched between the upper surface portion 241 and the contact surface portion 282, and the second fixing portion 21 is fixed to the right end of the tabletop 31. The second fixing portion 22 is fixed to the left end of the tabletop 31 in the same manner as the second fixing portion 21. As a result, the second fixing portions 21 and 22 are fixed to the tabletop 31. In other words, the first fixing portion 1 is fixed to the tabletop 31 via the second fixing portions 21 and 22. At this time, the first fixing portion 1 is fixed at a predetermined distance G1 from the tabletop 31 by the support portion 25 of the stay portion 23 (see FIG. 6), as shown in FIG. 2. In other words, the second fixing portions 21, 22 fix the first fixing portion 1 to the top plate 31 at a predetermined distance G1 in the direction in which the stay portion 23 protrudes (the up-down direction). In other words, the first wiring duct 41 and the second wiring duct 42 housed in the first fixing portion 1 are fixed at a distance from the top plate 31. This has the advantage that, for example, if a worker working on the top plate 31 spills liquid such as a drink on the top plate 31, the liquid is less likely to adhere to the first wiring duct 41 and the second wiring duct 42.

[0028] As shown in Figures 3, 5, and 6, the wiring duct fixture F1 further includes a connector holding portion 7. The connector holding portion 7 is provided, for example, on the stay portion 23 of the second fixing portion 21, and holds the connector portion 8. The connector holding portion 7 has an attachment portion 71 and a protrusion 72. The attachment portion 71 is formed in a flat plate shape that extends in the up-down direction. The protrusion 72 is provided continuous with the lower end of the attachment portion 71, and is formed in a flat plate shape that protrudes from the lower end of the attachment portion 71 in a direction (right side) in which the right end of the top plate 31 is inserted into the base portion 24.

[0029] The connector holding portion 7 is fixed to the second fixing portion 21 by fixing the attachment portion 71 to the support portion 25 with, for example, a screw. In other words, the connector holding portion 7 is provided above the base portion 24 which is provided below the support portion 25. In addition, the protrusion 72 of the connector holding portion 7 protrudes from the support portion 25 in the direction (right side) where the right end portion of the top plate 31 is inserted into the base portion 24.

[0030] As shown in FIGS. 3, 5 and 10, the connector portion 8 includes a first connector portion 81 and a second connector portion 82.

[0031] The first connector unit 81 electrically connects the first connection line W1 (first connection line W11) connected to the first wiring duct 41 via the feed-in 61 to the second connection line W2 (second connection line W21) connected to the power source 5 (first power source 51). The first power source 51 is, for example, an AC adapter connected to a commercial power source 30 (see FIG. 10), and converts AC power supplied from the commercial power source 30 into DC power and outputs it to the feed-in 61. The first connector unit 81 has a first connector 811 and a second connector 812. The first connector 811 is connected to the first connection line W11, and the second connector 812 is connected to the second connection line W21.

[0032] The second connector unit 82 electrically connects the first connection line W1 (first connection line W12) connected to the second wiring duct 42 via the feed-in 62 to the second connection line W2 (second connection line W22) connected to the power source 5 (second power source 52). The second power source 52 is, for example, an AC adapter connected to a commercial power source 30, and converts AC power supplied from the commercial power source 30 into DC power and outputs the DC power to the feed-in 62. The first power source 51 and the second power source 52 may be the same power source 5. In this case, the power source 5 has a circuit that converts AC power supplied from the commercial power source 30 into DC power and outputs the DC power to each of the feed-ins 61 and 62. The second connector unit 82 has a first connector 821 and a second connector 822. The first connector 821 is connected to the first connection line W12, and the second connector 822 is connected to the second connection line W22. In this embodiment, since the feed-ins 61 and 62 are housed in the right end portions of the grooves 11 and 12, respectively, the connector holding portion 7 is provided in the second fixed portion 21. When the feed-ins 61 and 62 are housed in the left end portions of the grooves 11 and 12, respectively, the connector holding portion 7 is provided in the second fixed portion 22.

[0033] As shown in FIG. 5, mating holes 721 and 722 are provided at the tip of the protrusion 72 of the connector holding portion 7. The first connector 811 of the first connector portion 81 is fitted into the mating hole 721 from above. The second connector 812 is detachably connected to the first connector 811 from below. The first connector 821 of the second connector portion 82 is fitted into the mating hole 722 from above. The second connector 822 is detachably connected to the first connector 821 from below. Here, the mating holes 721 and 722 are arranged side by side in the direction in which the first wiring duct 41 and the second wiring duct 42 face each other (front-rear direction). That is, as shown in FIG. 5, the connector holding portion 7 holds the first connector portion 81 and the second connector portion 82 so that they are lined up in the direction in which the first wiring duct 41 and the second wiring duct 42 face each other. This makes it easier to understand the correspondence between the first wiring duct 41 and the second wiring duct 42 and the first connector portion 81 and the second connector portion 82, thereby reducing the possibility of incorrect wiring occurring.

[0034] 6, the protrusion 72 of the connector holding portion 7 protrudes from the support portion 25 of the stay portion 23 in the direction in which the right end of the top plate 31 is inserted into the base portion 24. More specifically, the protrusion 72 extends from the stay portion 23 to the outside (right side) of the stay portion 23 in the direction in which the right end of the top plate 31 is inserted into the base portion 24, and holds the connector portion 8 (first connector portion 81 and second connector portion 82) outside the stay portion 23 so as not to come into contact with the stay portion 23. In other words, the connector portion 8 (first connector portion 81 and second connector portion 82) , support The connectors 811 and 821 are held by the protrusions 72 so as to have a gap between them and the connector 25. This improves the workability of attaching and detaching the first connector 811 and the second connector 812, and the work of attaching and detaching the first connector 821 and the second connector 822.

[0035] As shown in Figures 1 to 3 and 7, each of the second fixing parts 21, 22 further has a cover part 29. The cover parts 29 are provided on both ends in the longitudinal direction (left-right direction) of the first fixing part 1 so as to cover at least a part of the stay part 23. In detail, as shown in Figure 7, the cover part 29 covers the stay part 23 except for the lower surface part 243 of the base part 24.

[0036] Since the connector holding portion 7 is provided on the support portion 25 of the stay portion 23 of the second fixed portion 21, the cover portion 29 is provided at the right end portion of the first fixed portion 1 so as to cover the connector holding portion 7. This protects the first connection lines W11, W12 and the second connection lines W21, W22 connected to the connector portion 8 held by the connector holding portion 7 from the outside, reducing the possibility of the first connection lines W11, W12 and the second connection lines W21, W22 being disconnected due to contact from the outside.

[0037] Furthermore, the cover portion 29 has a mating portion on its inner surface, and the mating portion on the inner surface of the cover portion 29 is mated with at least a part of the second fixing portion 2 other than the cover portion 29 (for example, the stay portion 23), thereby detachably fixing the cover portion 29 to the stay portion 23. This allows the user of the duct system 100 to manually remove the cover portion 29 without using tools, for example, when plugging or unplugging the connector portion 8.

[0038] Here, the base portion 24 of the stay portion 23 is fixed to the top plate 31, and the insertion portion 26 of the stay portion 23 is fixed to the first fixed portion 1. Therefore, the stay portion 23 has high resistance to vibration and impact, and by attaching the cover portion 29 to the stay portion 23, the stability of the cover portion 29 can be ensured. Note that the cover portion 29 may be attached detachably by engaging with the left and right ends of the first fixed portion 1.

[0039] The cover portion 29 also has an opening 291 that opens downward. The opening 291 is provided below the top plate 31 in the up-down direction. For example, the opening 291 is provided at approximately the same height as the lower surface portion 243 of the base portion 24 that is located below the top plate 31.

[0040] Furthermore, in the second fixing portion 21, the second connection lines W21, 22 connected to the first connector portion 81 and the second connector portion 82, respectively, held by the connector holding portion 7, are drawn downward from the opening 291. Here, as described above, the opening 291 is provided below the top plate 31 in the up-down direction, and therefore the second connection lines W21, 22 drawn out from the opening 291 are less likely to be wired on the top plate 31, and the possibility of them interfering with work on the top plate 31 can be reduced.

[0041] (2.2) Wiring duct 4, each of the first wiring duct 41 and the second wiring duct 42 has a duct rail 43 and two conductive bars 44. The duct rail 43 includes a first rail 431 and two second rails 432. Here, the first wiring duct 41 and the second wiring duct 42 have a symmetrical structure in the front-to-rear direction, so the following description will focus on the first wiring duct 41, and a detailed description of the second wiring duct 42 will be omitted.

[0042] The first rail 431 has a rectangular cylindrical shape. The first rail 431 is made of, for example, metal. The axial direction (length direction) of the first rail 431 is along the left-right direction. The first rail 431 includes a groove 4310. The groove 4310 is formed along the length direction (left-right direction) of the duct rail 43. More specifically, the groove 4310 is formed across both ends of the duct rail 43 in the length direction. Two conductive bars 44 are housed in the groove 4310.

[0043] The first rail 431 further includes two fitting portions 4311 and two mounting grooves 4312 .

[0044] Each of the two fitting portions 4311 is a groove. The two fitting portions 4311 are provided on the inner surface of the groove portion 4310. The two fitting portions 4311 are formed along the length direction (left-right direction) of the duct rail 43. More specifically, the two fitting portions 4311 are formed across both ends of the duct rail 43 in the length direction. The two fitting portions 4311 are fitted into the adapter 9A (see FIG. 11). This allows the adapter 9A to be attached to the first wiring duct 41.

[0045] The two mounting grooves 4312 are provided on the inner surface of the groove portion 4310. Of the two fitting portions 4311 and the two mounting grooves 4312, the two fitting portions 4311 are provided closer to the opening of the groove portion 4310. The two mounting grooves 4312 are formed along the length direction (left-right direction) of the duct rail 43. More specifically, the two mounting grooves 4312 are formed across both ends of the duct rail 43 in the length direction.

[0046] The two mounting grooves 4312 correspond one-to-one to the two second rails 432. A corresponding second rail 432 is fitted into each mounting groove 4312. In other words, the two second rails 432 are attached to the first rail 431 facing each other in the vertical direction. The first rail 431 has two protrusions 4313 for preventing the two second rails 432 from falling off.

[0047] Each of the two second rails 432 has a length in the left-right direction. The cross section of the second rail 432 perpendicular to the left-right direction is U-shaped. The second rail 432 has electrical insulation properties. The second rail 432 is made of a synthetic resin material such as PVC (polyvinyl chloride). The second rail 432 holds the conductive bar 44 inside.

[0048] Each of the two conductive bars 44 (the first conductive bar 44A and the second conductive bar 44B) has a length in the left-right direction. The first conductive bar 44A or the second conductive bar 44B is provided across from the right end to the left end of the duct rail 43. The first conductive bar 44A or the second conductive bar 44B is electrically connected to the corresponding electric wires W31 and W32 (see FIG. 9 ) via a feed-in 61. Here, the electric wires W31 and W32 are electric wires included in the first connection line W11. In this embodiment, the first conductive bar 44A is electrically connected to the positive electric wire W31, and the second conductive bar 44B is electrically connected to the negative electric wire W32, and a DC voltage is supplied to the first conductive bar 44A and the second conductive bar 44B.

[0049] (2.3) Feed-in 3, the feed-ins 61 and 62 correspond one-to-one to the first wiring duct 41 and the second wiring duct 42. Since the feed-ins 61 and 62 have a symmetrical structure in the front-to-rear direction, the following description will focus on the feed-in 61, and a detailed description of the feed-in 62 will be omitted.

[0050] The feed-in 61 has a configuration for electrically connecting the first conductive bar 44A and the second conductive bar 44B of the first wiring duct 41 to the corresponding electric wires W31 and W32, respectively. That is, the first conductive bar 44A and the second conductive bar 44B are electrically connected to the corresponding electric wires W31 and W32 via the feed-in 61. The configuration of the feed-in 61 will be described below with reference to FIGS. 8 and 9.

[0051] The feed-in 61 includes an outer box 63, a main body 64, and two contacts 65 (including a first contact 65A and a second contact 65B).

[0052] The main body 64 has a rectangular parallelepiped shape with a left-right dimension greater than its front-rear and up-down dimensions. The main body 64 has a first block 641 on the front side and a second block 642 on the rear side. The main body 64 is formed by joining the first block 641 and the second block 642 with screws 643. Note that the "left-right direction," "front-rear direction," and "up-down direction" referred to here refer to directions in a state in which the feed-in 61 is housed in the first wiring duct 41, as shown in FIG. 3. The main body 64 houses two contacts 65 (including a first contact 65A and a second contact 65B). The left end of the main body 64 in the left-right direction is inserted into the first wiring duct 41, as shown in FIG. 8. Specifically, the feed-in 61 is inserted into the first wiring duct 41 so that the first contact 65A contacts the first conductive bar 44A and the second contact 65B contacts the second conductive bar 44B.

[0053] The shape of outer box 63 is a C-shaped rectangular parallelepiped when viewed from the side. Outer box 63 is attached to main body 64 using screws 644 so as to cover the portion of main body 64 that is exposed from first wiring duct 41.

[0054] A first connection line W11 is introduced into the main body 64 from the right end thereof, which is opposite to the left end thereof inserted into the first wiring duct 41. The first connection line W11 has two conductors C1 and C2, and the conductor C1 is connected to the first contactor 65A by welding, and the conductor C2 is connected to the second contactor 65B by welding.

[0055] The first connection line W11 is connected to a first connector 811. The first connector 811 is a two-pole connector.

[0056] A second connector 812 provided on a second connection line W21 connected to a first power source 51 (see FIG. 10) is connected to the first connector 811. The first connector 811 is provided with a structure that prevents it from being connected with reverse polarity to the second connector 812, so that it is possible to reduce the possibility of connecting the first connector 811 to the second connector 812 with reverse polarity during construction on site.

[0057] Furthermore, the first connector 811 is connected to the main body 64 via the first connection wire W11, and the two electric wires W31, W32 included in the first connection wire W11 are pre-connected to the first contactor 65A and the second contactor 65B. Therefore, by connecting the first connector 811 of the feed-in 61 to the second connector 812 at the construction site, a DC voltage with the correct polarity is applied to the first conductive bar 44A and the second conductive bar 44B provided in the first wiring duct 41, thereby reducing the possibility of incorrect construction at the construction site.

[0058] (2.4) Adapter As shown in FIG. 10, the duct system 100 supplies power to the electric device 20 via the power receiving device 9 connected to the first wiring duct 41 and the second wiring duct 42.

[0059] 11 , the power receiving device 9 includes an adapter 9A. The adapter 9A has a connector to which a connector 201 provided on an electric wire of the electric device 20 can be connected. For example, when the adapter 9A is connected to the first wiring duct 41, the adapter 9A receives a supply of DC power via the first conductive bar 44A and the second conductive bar 44B of the first wiring duct 41. When the connector 201 provided on the electric wire of the electric device 20 is connected to the connector of the adapter 9A, DC power is supplied from the first wiring duct 41 to the adapter 9A. The adapter 9A can be attached to the first wiring duct 41 at any position within the region where the groove portion 4310 is provided, and can be electrically connected to the conductive bar 44.

[0060] The adapter 9A has a housing 91 and two power receiving terminals (not shown).

[0061] The housing 91 has a rectangular parallelepiped shape. The housing 91 has a first socket 911 and a second socket 912. The first socket 911 is connected to the connector 20. 1 andThe first receptacle 911 is a receptacle for a USB Type-A plug as a connector 201. The second receptacle 912 is a receptacle for a USB Type-C plug as a connector 201. In other words, the first receptacle 911 is of a different standard than the second receptacle 912. The first receptacle 911 is also of a different size than the second receptacle 912.

[0062] The first outlet 911 and the second outlet 912 are provided on a surface (connector mounting surface 901) facing away from the first wiring duct 41 when the adapter 9A is attached to the first wiring duct 41. The first outlet 911 and the second outlet 912 are aligned in the vertical direction when the adapter 9A is attached to the first wiring duct 41.

[0063] The two power receiving terminals protrude from the housing 91 on the side opposite to the connector mounting surface 901. The tips of the two power receiving terminals are bent in opposite directions. When the adapter 9A is attached to the first wiring duct 41, one of the two power receiving terminals is connected to the first conductive bar 44A on the positive side, and the other is connected to the second conductive bar 44B on the negative side.

[0064] The adapter 9A further includes a voltage converter. The voltage converter converts the DC voltage received at the two power receiving terminals into a DC voltage of a desired voltage value. The DC voltage whose voltage value has been converted by the voltage converter is output from the first outlet 911 and the second outlet 912. The DC voltage is applied to the electrical device 20 (see FIG. 10 ) via a cable including a connector 201 connected to the first outlet 911 or the second outlet 912.

[0065] (2.5) Partition 4, the partition unit 10 has a partition 101 and a partition fixing part 102 for fixing the partition 101 to the first fixing part 1. The "partition" is also called a room divider or a screen.

[0066] As shown in Figures 1 and 2, the partition fixing part 102 is elongated in the left-right direction. The partition fixing part 102 is installed on the first fixing part 1. When viewed from the right side, the partition fixing part 102 has a U-shape that is open on the bottom, as shown in Figure 4. The partition fixing part 102 is installed on the first fixing part 1 so that the top of the first fixing part 1 is covered by the U-shaped opening. The partition fixing part 102 is fixed to the first fixing part 1 from above with screws or the like.

[0067] The partition fixing part 102 has a clamping part 103 extending in the left-right direction in the center in the front-rear direction. The clamping part 103 clamps, for example, the flat plate-shaped partition 101 in the thickness direction in a clamping groove 1031 provided from the left end to the right end of the clamping part 103.

[0068] The partition 101 is translucent and is made of, for example, acrylic resin. The thickness direction of the partition 101 is aligned with the front-rear direction.

[0069] As a result, the space above the tabletop 31 is divided into a front space and a rear space by the partition 101. Some people (hereinafter referred to as "first people") sit in front of the desk 3, and some other people (hereinafter referred to as "second people") sit behind the desk 3. Because the space between the first people and the second people is separated by the partition 101, the possibility of droplet infection occurring between the first people and the second people can be reduced.

[0070] (3) Variations The above embodiment is merely one of various embodiments of the present disclosure, and various modifications can be made to the above embodiment depending on the design and the like as long as the object of the present disclosure can be achieved.

[0071] Modifications of the above embodiment are listed below. The modifications described below can be applied in appropriate combinations.

[0072] The number of individual components shown in the above embodiment is merely an example and is not limited to the number shown in the embodiment. For example, the duct system 100 is not limited to having two wiring ducts 4, but may have one or three or more wiring ducts 4. Furthermore, the duct system 100 is not limited to having one first fixing portion 1, but may have two or more first fixing portions 1. Furthermore, the duct system 100 is not limited to having two second fixing portions 2, but may have one or three or more second fixing portions 2. Furthermore, the duct system 100 is not limited to having one partition 101, but may have two or more partitions 101.

[0073] Two or more wiring ducts 4 may be attached to the first fixing portion 1. Furthermore, the voltage of the conductive bar 44 may be different for each of the two or more wiring ducts 4. Furthermore, the standard of the attachable adapter 9A may be different for each of the two or more wiring ducts 4.

[0074] One wiring duct 4 may be fixed to two or more first fixing portions 1.

[0075] The configuration of the second fixing part 2 is not limited to a configuration in which it is fixed to the top plate 31 by the clamp part 28. The second fixing part 2 may be configured to be fixed to the top plate 31 by screwing, for example.

[0076] The configuration of the first fixing part 1 is not limited to a configuration that houses the wiring duct 4. For example, the first fixing part 1 may be configured to support the wiring duct 4 at one location or multiple locations. The first fixing part 1 may be configured to support the wiring duct 4 with a cantilever beam structure or a doubly supported beam structure.

[0077] The protruding portion 72 of the connector holding portion 7 is not limited to a configuration in which it extends outward beyond the stay portion 23 in the direction in which the right end portion of the top panel 31 is inserted into the base portion 24, but may be configured to extend to the inside of the base portion 24 that protrudes outward from the stay portion 23. In other words, the base portion 24 may be configured to be located below the connector portion 8 held at the tip end of the protruding portion 72. In this case, the mounting position of the connector holding portion 7 to the second fixing portion 2 in the vertical direction may be changeable so that the connector portion 8 does not come into contact with the base portion 24.

[0078] (summary) As described above, the wiring duct fixture (F1) according to the first aspect includes a first fixing portion (1), a second fixing portion (2), and a connector holding portion (7).
