The wiring duct fixture F1 according to the implementation mode of the present invention, and the duct system 100 including the wiring duct fixture F1 are described in detail with reference to the drawings. In addition, the various drawings described in the following implementation modes are schematic diagrams, and the size and thickness of each component element in each drawing, and the respective ratios do not necessarily reflect the actual size ratio. In addition, the implementation modes and modifications described below are merely examples of the present invention, and the present invention is not limited to the implementation modes and modifications. Even those other than these implementation modes and modifications can be modified in various ways according to the design, etc. as long as they do not deviate from the scope of the technical idea of the present invention. In addition, the following implementation modes (including modifications) can also be implemented in appropriate combinations.

(1) Overview First, the overview of the wiring duct fixture F1 according to this embodiment will be described with reference to Figures 1 to 3 and 10.

The wiring duct fixture F1 of this embodiment is used to fix the wiring duct 4 (so-called DC duct) for supplying DC power to the electrical equipment 20 (refer to FIG. 10 ) to daily appliances.

As shown in Figures 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 in the shape of a long strip and is installed with the wiring duct 4. The second fixing portion 2 is arranged at "at least one end of the long side direction of the first fixing portion 1" to fix the first fixing portion 1 relative to the flat top plate 31. The connector holding portion 7 is arranged on the second fixing portion 2 to hold the connector portion 8, which is electrically connected to: the first connection line W1 connected to the wiring duct 4 and the second connection line W2 connected to the power supply 5 (refer to Figure 10).

In this embodiment, the daily utensil, i.e., the table 3, includes a top plate 31. Here, the so-called daily utensil is a general term for furniture and equipment used at home or outside of home. In addition, the daily utensil including the top plate 31 is not limited to the table 3, and can also be a workbench and a workbench used as a loading platform.

According to the above configuration, by fixing the connector portion 8 to the connector fixing portion 7 "arranged on the second fixing portion 2", the area where 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. In this way, the first connection line W1 and the second connection line W2 are not easily wired on the top plate 31, and the possibility of "reducing the convenience of the daily utensil (table 3) including the top plate 31" can be reduced.

(2) Details The following is a detailed description of the duct system 100 having the wiring duct fixture F1. In the following description, in Figures 1 to 3 and 5 to 7, the direction "parallel to one side of the square top plate 31" is defined as the left-right direction, the horizontal direction perpendicular to the left-right direction is defined as the front-back 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 use direction of the duct system 100. In addition, the arrows indicating the front-back, left-right, and up-down in Figures 1 to 3 and 5 to 7 are only marks for explanation and have no entity.

The duct system 100, as shown in FIGS. 1 and 2, includes: a wiring duct fixture F1, two (only one is shown in FIGS. 1 and 2) wiring ducts 4, two (only one is shown in FIGS. 1 and 2) feeders 6 for supplying power from a power source 5 (see FIG. 10) to the two wiring ducts 4, two (only one is shown in FIGS. 1 and 2) end covers CP1, and a partition portion 10.

The duct system 100 fixes the wiring duct 4 to the ceiling 31 of the table 3 by means of the wiring duct fixture F1. The wiring duct 4 supplies power to the electrical equipment 20 (refer to FIG. 10 ) that the operator uses on the ceiling 31. In addition, the type of electrical equipment 20 is not particularly limited. Examples of electrical equipment 20 include computer terminals (personal computers, smart phones, and tablet terminals, etc.), computer terminal accessories (monitors, speakers, and microphones, etc.), lighting equipment (desk lamps, etc.), web cameras, sensors (temperature sensors, humidity sensors, and light intensity sensors, etc.), game consoles, and air conditioning equipment (desktop fans, etc.).

As shown in FIG1 , the table 3 includes: a top plate 31 that is square in shape when viewed from above, two legs 32, and two support platforms 33. One of the two legs 32 protrudes downward from the vicinity of the right end of the top plate 31, and the other of the two legs 32 protrudes downward from the vicinity of the left end of the top plate 31. The two support platforms 33 correspond to the two legs 32 in a one-to-one manner. Each support platform 33 is connected to the lower end of the corresponding leg 32 to support the leg 32.

(2.1) Wiring duct fixture As mentioned above, the wiring duct fixture F1 includes a first fixing portion 1 and a second fixing portion 2.

As shown in FIG. 1 and FIG. 2 , the first fixing portion 1 is in the shape of a long strip that is longer in the left-right direction. Furthermore, as shown in FIG. 4 , the front and rear surfaces of the first fixing portion 1 are respectively formed with groove portions 11 and 12 in the left-right direction. The groove portion 11 is formed with an opening toward the front on the front surface of the first fixing portion 1, and the groove portion 12 is formed with an opening toward the rear on the rear surface of the first fixing portion 1. Here, in this embodiment, the groove portion 11 accommodates one wiring duct trough 4 (first wiring duct trough 41), and the groove portion 12 accommodates one wiring duct trough 4 (second wiring duct trough 42). That is, in the first fixing portion 1, two wiring duct troughs 4 (first wiring duct trough 41, second wiring duct trough 42) are installed opposite to each other in the front-rear direction. Furthermore, the groove portions 11 and 12 may each accommodate a plurality of wiring duct troughs 4.

Furthermore, as shown in FIG. 3 and FIG. 5 , the right end of the groove portion 11 accommodates the feeder 6 (feeder 61) that “supplies power to the first wiring duct 41”, and as shown in FIG. 1 and FIG. 2 , the left end of the groove portion 11 accommodates the end cover CP1. Specifically, the first wiring duct 41 that “receives the end cover CP1 and the feeder 61 at both ends in the left and right directions” is accommodated in the groove portion 11. The right end of the groove portion 12 accommodates the feeder 6 (feeder 62) that “supplies power to the second wiring duct 42”, and the left end of the groove portion 12 accommodates the end cover CP1. Specifically, the second wiring duct 42 that “receives the end cover CP1 and the feeder 62 at both ends in the left and right directions” is accommodated in the groove portion 12. Furthermore, the feeder 61 may be accommodated at the left end of the groove 11, and the end cap CP1 may be accommodated at the right end of the groove 11. Furthermore, the feeder 62 may be accommodated at the left end of the groove 12, and the end cap CP1 may be accommodated at the right end of the groove 12.

As shown in FIG. 1 and FIG. 2 , the second fixing portion 2 is respectively provided at both ends of the first fixing portion 1 in the longitudinal direction. That is, the wiring duct trough fixture F1 includes two second fixing portions 2 (second fixing portions 21, 22). The second fixing portions 21, 22 fix the first fixing portion 1 relative to the top plate 31. That is, the second fixing portions 21, 22 fix the first wiring duct trough 41 and the second wiring duct trough 42 relative to the top plate 31. Hereinafter, the second fixing portion 21 disposed at the "right end portion in the longitudinal direction of the first fixing portion 1" among the second fixing portions 21, 22 will be described. The second fixing portion 22 disposed at the "left end portion in the longitudinal direction of the first fixing portion 1" has a structure that is symmetrical with the second fixing portion 21 described below, so a detailed description is omitted.

As shown in FIG. 3 , FIG. 5 and FIG. 6 , the second fixing portion 21 includes a support strip portion 23 protruding from the right end portion in the longitudinal direction of the first fixing portion 1 toward the top plate 31 side.

The support bar portion 23 includes: a base portion 24, in which a portion of the top plate 31 is inserted. Specifically, as shown in FIG. 3 , FIG. 5 and FIG. 6 , the support bar portion 23 includes: a support portion 25, which is in the form of a flat plate and parallel to the up-down direction; an insertion portion 26, which is in the form of a flat plate and is connected to and arranged at the upper end of the support portion 25, and protrudes from the upper end of the support portion 25 toward the side (left side) of the first fixing portion 1; and a base portion 24, which is connected to and arranged at the lower end of the support portion 25.

The insertion portion 26 is inserted into the mounting groove 13 "set in the left-right direction on the bottom surface of the first fixing portion 1" from the right side of the first fixing portion 1. The second fixing portion 21 is fixed to the right end of the first fixing portion 1 by fixing the insertion portion 26 to the first fixing portion 1 from below with, for example, screws, while the insertion portion 26 is inserted into the mounting groove 13.

As shown in FIG6 , the base 24 includes: a top portion 241, which is in the shape of a plate and protrudes from the lower end of the support portion 25 to the "side opposite to the first fixing portion 1 (right side)"; a contact portion 242, which is in the shape of a plate and protrudes downward from the right end of the top portion 241; and a bottom portion 243, which is in the shape of a plate and protrudes to the left from the lower end of the contact portion 242. That is, the top portion 241 and the bottom portion 243 face each other in the vertical direction with the contact portion 242 sandwiched therebetween. Furthermore, the top portion 241, the contact portion 242, and the bottom portion 243 form a recess 27 that "opens to the left side".

The second fixing portion 21 is further provided with a clamping portion 28. As shown in FIG6 , the clamping portion 28 includes: a support shaft 281 having an up-down direction as an axial direction; a contact portion 282 connected to the upper end of the support shaft 281; and an actuating button 283 fixed to the lower end of the support shaft 281. The contact portion 282 is connected in a manner that allows arbitrary rotation with the axis of the support shaft 281 as the center. The support shaft 281 is, for example, provided with a threaded groove that is screwed into the "open screw hole 244 of the bottom portion 243 of the base 24". That is, the contact portion 282 connected to the upper end of the support shaft 281 is located in the recess 27 of the base 24, and by rotating the actuating button 283, the contact portion 282 can move in the up-down direction between the top portion 241 and the bottom portion 243.

Here, the right end of the top plate 31 is inserted between the top surface 241 and the contact surface 282 until it is "at the position of contacting the contact surface 242". By rotating the actuating button 283 in this state to move the contact surface 282 upward, the top surface 241 and the contact surface 282 clamp the top plate 31, and the second fixing portion 21 is fixed to the right end of the top plate 31. In addition, the second fixing portion 22 is fixed to the left end of the top plate 31 in the same way as the second fixing portion 21. In this way, the second fixing portions 21 and 22 are fixed to the top plate 31. That is, the first fixing portion 1 is fixed to the top plate 31 through the second fixing portions 21 and 22. At this time, as shown in FIG. 2 , the first fixing portion 1 is fixed by the support portion 25 of the support bar portion 23 (see FIG. 6 ) at a predetermined interval G1 from the top plate 31. In other words, the second fixing portions 21 and 22 fix the first fixing portion 1 in a manner of “separating the first fixing portion 1 from the top plate 31 at a predetermined interval G1” in the direction in which the support bar portion 23 protrudes (the vertical direction). That is, the first wiring duct trough 41 and the second wiring duct trough 42 accommodated in the first fixing portion 1 are separated from the top plate 31 and fixed. Thereby, when, for example, an operator working on the top plate 31 sprinkles water such as drinks on the top plate 31, the water is not easily attached to the first wiring duct trough 41 and the second wiring duct trough 42, which is an advantage.

As shown in Fig. 3, Fig. 5 and Fig. 6, the wiring duct fixture F1 further includes a connector holding portion 7. The connector holding portion 7 is, for example, disposed on the brace portion 23 of the second fixing portion 21, and holds the connector portion 8. The connector holding portion 7 includes a mounting portion 71 and a protruding portion 72. The mounting portion 71 is in the shape of a flat plate and is parallel to the up-down direction. The protruding portion 72 is in the shape of a flat plate and is connected to the lower end of the mounting portion 71 and protrudes from the lower end of the mounting portion 71 in the direction (right side) of "the right end of the top plate 31 is inserted into the base 24".

The connector holding portion 7 is fixed to the second fixing portion 21 by fixing the mounting portion 71 to the supporting portion 25 with screws, for example. That is, the connector holding portion 7 is arranged on the upper side relative to the "base 24 provided on the lower side of the supporting portion 25". In addition, the protruding portion 72 of the connector holding portion 7 protrudes from the supporting portion 25 in the direction (right side) of "the right end of the top plate 31 is inserted into the base 24".

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

The first connector part 81 is electrically connected to: the first connection line W1 (first connection line W11) connected to the first wiring duct 41 through the feeder 61, and 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 the commercial power source 30 (refer to Figure 10), which converts the "AC power supplied from the commercial power source 30" into DC power and outputs it to the feeder 61. The first connector part 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.

The second connector part 82 is electrically connected to: the first connection line W1 (first connection line W12) connected to the second wiring duct 42 through the feeder 62, and 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 the commercial power source 30, which converts the "AC power supplied from the commercial power source 30" into DC power and outputs it to the feeder 62. In addition, the first power source 51 and the second power source 52 can be the same power source 5. In this case, the power source 5 has a circuit that converts the "AC power supplied from the commercial power source 30" into DC power and outputs the DC power to the feeders 61 and 62 respectively. The second connector part 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 addition, in this embodiment, since the right end of the groove portion 11 and the right end of the groove portion 12 respectively receive the feeder 61 and the feeder 62, the connector holding portion 7 is arranged on the second fixing portion 21. When the left end of the groove portion 11 and the left end of the groove portion 12 respectively receive the feeder 61 and the feeder 62, the connector holding portion 7 is arranged on the second fixing portion 22.

As shown in FIG. 5 , the front end portion of the protrusion 72 of the connector holding portion 7 is provided with engaging holes 721 and 722. In the engaging hole 721, the first connector 811 of the first connector portion 81 is inserted from the upper side. The second connector 812 is connected to the first connector 811 from the lower side in a detachable manner. In the engaging hole 722, the first connector 821 of the second connector portion 82 is inserted from the upper side. The second connector 822 is connected to the first connector 821 from the lower side in a detachable manner. Here, the engaging holes 721 and 722 are arranged side by side in the direction (front-rear direction) in which the first wiring duct 41 and the second wiring duct 42 are opposite. That is, as shown in Fig. 5, the connector holding portion 7 holds the first connector portion 81 and the second connector portion 82 side by side in the direction of "the first wiring duct 41 and the second wiring duct 42 facing each other". Thus, the corresponding relationship between the first wiring duct 41 and the second wiring duct 42, and the first connector portion 81 and the second connector portion 82 is clear and easy to understand, which can reduce the possibility of incorrect wiring.

As shown in FIG. 6 , the protrusion 72 of the connector holding portion 7 protrudes from the support portion 25 of the support bar portion 23 in the direction of “the right end of the top plate 31 is inserted into the base portion 24”. More specifically, the protrusion 72 extends from the support bar portion 23 to the outer side (right side) of the support bar portion 23 in the direction of “the right end of the top plate 31 is inserted into the base portion 24”, and holds the connector portion 8 (the first connector portion 81 and the second connector portion 82) on the outer side of the support bar portion 23 in a manner that does not contact the support bar portion 23. In other words, the connector portion 8 (the first connector portion 81 and the second connector portion 82) is held on the protrusion 72 in a manner that is spaced relative to the support portion 25 of the support bar portion 23. Thereby, the operability of the loading and unloading operation of the first connector 811 and the second connector 812 and the loading and unloading operation of the first connector 821 and the second connector 822 can be improved.

As shown in Figs. 1 to 3 and 7, the second fixing parts 21 and 22 each further include a cover 29. The cover 29 is disposed at both ends of the first fixing part 1 in the longitudinal direction (left-right direction) so as to cover at least a portion of the stay 23. Specifically, as shown in Fig. 7, the cover 29 covers the stay 23 except for the bottom surface 243 of the base 24.

Since the connector holding portion 7 is disposed on the supporting portion 25 of the supporting strip portion 23 of the second fixing portion 21, the cover portion 29 is disposed at the right end portion of the first fixing portion 1 in a manner of covering the connector holding portion 7. Thus, the first connecting wires W11, W12 and the second connecting wires W21, W22 connected to the "connector portion 8 held by the connector holding portion 7" are protected from external contact, thereby reducing the possibility of "the first connecting wires W11, W12 and the second connecting wires W21, W22 being disconnected due to external contact".

Furthermore, the cover 29 has an engaging portion on the inner surface, and the engaging portion on the inner surface of the cover 29 engages with at least a portion of the second fixing portion 2 other than the cover 29 (e.g., the support strip portion 23), so that the cover 29 and the support strip portion 23 are fixed in a detachable manner. Thus, the user of the tube slot system 100 can manually remove the cover 29 without using tools, for example, when plugging and unplugging the connector portion 8.

Here, the base 24 of the support bar 23 is fixed to the top plate 31, and the insertion portion 26 of the support bar 23 is fixed to the first fixing portion 1. Therefore, the support bar 23 is strong against vibration or impact, and the cover 29 is mounted on the support bar 23 to ensure the firmness of the cover 29. In addition, the cover 29 is engaged with the left and right ends of the first fixing portion 1 and is mounted in a detachable manner.

In addition, the cover 29 has an opening 291 that is "opened downward". The opening 291 is disposed below the top plate 31 in the vertical direction. For example, the opening 291 is disposed at substantially the same height as the bottom surface 243 of the base 24 located below the top plate 31.

Furthermore, in the second fixing portion 21, the second connection wires W21, 22 respectively connected to the "first connector portion 81 and the second connector portion 82 held in the connector holding portion 7" are pulled out from the opening portion 291 to the lower side. Here, as mentioned above, since the opening portion 291 is disposed at a lower side than the top plate 31 in the vertical direction, the "second connection wires W21, 22 pulled out from the opening portion 291" are not easily wired on the top plate 31, which can reduce the possibility of "hindering the operation on the top plate 31".

(2.2) Wiring duct

As shown in FIG4 , the first wiring duct 41 and the second wiring duct 42 each have a duct rail 43 and two conductive bars 44. The duct rail 43 includes a first rail 431 and two second rails 432. Here, since the first wiring duct 41 and the second wiring duct 42 have a symmetrical structure in the front-rear direction, the following description is directed to the first wiring duct 41, and the detailed description of the second wiring duct 42 is omitted.

The first rail 431 is in the shape of a square tube. The first rail 431 is made of metal, for example. The axial direction (longitudinal direction) of the first rail 431 is parallel to the left-right direction. The first rail 431 includes a groove portion 4310. The groove portion 4310 is formed along the long-side direction (left-right direction) of the tube slot rail 43. More specifically, the groove portion 4310 is formed across both ends of the long-side direction of the tube slot rail 43. The groove portion 4310 accommodates two conductive bars 44.

The first track 431 further includes two engaging portions 4311 and two mounting grooves 4312 .

The two interlocking parts 4311 are grooves. The two interlocking parts 4311 are provided on the inner surface of the groove part 4310. The two interlocking parts 4311 are formed along the long side direction (left-right direction) of the tube groove track 43. In detail, the two interlocking parts 4311 are formed across the two ends of the long side direction of the tube groove track 43. The two interlocking parts 4311 are interlocked in the adapter 9A (refer to FIG. 11). Therefore, the adapter 9A is installed in the first wiring tube groove 41.

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 near the opening of the groove portion 4310. The two mounting grooves 4312 are formed along the long side direction (left-right direction) of the tube groove track 43. In detail, the two mounting grooves 4312 are formed across the two ends of the long side direction of the tube groove track 43.

The two mounting grooves 4312 correspond to the two second rails 432 in a one-to-one manner. Each mounting groove 4312 has a corresponding second rail 432 embedded therein. That is, the two second rails 432 face each other in the vertical direction and are mounted on the first rail 431. The first rail 431 has two protrusions 4313 for preventing the two second rails 432 from falling off.

The two second rails 432 have long sides in the left and right directions. The second rail 432 forms a U-shape in a "section perpendicular to the left and right directions". The second rail 432 has electrical insulation. The second rail 432 is formed of a synthetic resin material such as polyvinyl chloride (PVC). The conductive strip 44 is fixedly held inside the second rail 432.

The two conductive bars 44 (the first conductive bar 44A and the second conductive bar 44B) have long sides in the left and right directions, respectively. The first conductive bar 44A or the second conductive bar 44B is arranged horizontally from the right end of the tube slot track 43 to the left end. The first conductive bar 44A or the second conductive bar 44B is electrically connected to the corresponding wires W31 and W32 (refer to Figure 9) through the feeder 61. Here, the wires W31 and W32 are wires included in the first connecting wire W11. In this embodiment, the first conductive bar 44A is electrically connected to the wire W31 on the positive side, and the second conductive bar 44B is electrically connected to the wire W32 on the negative side. The first conductive bar 44A and the second conductive bar 44B receive a DC voltage supply.

(2.3) Feeder As shown in FIG3 , the feeders 61 and 62 correspond to the first wiring duct 41 and the second wiring duct 42 in a one-to-one manner. Since the feeders 61 and 62 have a symmetrical structure in the front-rear direction, the following description is focused on the feeder 61, and the detailed description of the feeder 62 is omitted.

The feeder 61 has a structure for "electrically connecting the first conductive strip 44A and the second conductive strip 44B of the first wiring duct 41 to the corresponding wires W31 and W32 respectively". That is, the first conductive strip 44A and the second conductive strip 44B are electrically connected to the corresponding wires W31 and W32 through the feeder 61. The structure of the feeder 61 is described below with reference to FIG. 8 and FIG. 9.

The feeder 61 includes a housing 63, a body 64, and two contacts 65 (including a first contact 65A and a second contact 65B).

The body 64 is in the shape of a cube, and the dimension in the left-right direction is larger than the dimension in the front-back direction and the dimension in the up-down direction. The body 64 includes a first block 641 on the front side and a second block 642 on the rear side. The body 64 is constructed by fastening the first block 641 and the second block 642 with screws 643. In addition, the so-called "left-right direction", "front-back direction" and "up-down direction" here represent the directions in the state of "the feeder 61 is stored in the first wiring duct groove 41 as shown in Figure 3". The body 64 stores two contacts 65 (including a first contact 65A and a second contact 65B). As shown in Figure 8, the left end of the body 64 in the left-right direction is inserted into the inside of the first wiring duct groove 41. Specifically, the feeder 61 is inserted into the first wiring duct 41 in such a manner that the first contact 65A contacts the first conductive strip 44A, and the second contact 65B contacts the second conductive strip 44B.

The outer shell 63 is formed into a C-shaped cube when viewed from the side. The outer shell 63 is mounted on the main body 64 using screws 644 so that the main body 64 covers the portion exposed from the first wiring duct groove 41.

In the body 64, the first connection wire W11 is introduced into the body 64 from the right end "opposite to the left end inserted into the first wiring duct groove 41". The first connection wire W11 has two conductors C1 and C2. The conductor C1 is connected to the first contact 65A by welding, and the conductor C2 is connected to the second contact 65B by welding.

The first connection line W11 is connected to a first connector 811. The first connector 811 is a diode connector.

The first connector 811 is connected to the second connector 812, and the second connector 812 is arranged on the second connection line W21 connected to the first power source 51 (refer to FIG. 10). Since the first connector 811 is provided with a structure to "prevent connection with reverse polarity relative to the second connector 812", the possibility of "connecting the first connector 811 with reverse polarity at the second connector 812" during on-site construction can be reduced.

Furthermore, the first connector 811 is connected to the main body 64 via the first connection line W11, and the two wires W31 and W32 included in the first connection line W11 are pre-connected to the first contact 65A and the second contact 65B. Therefore, at the construction site, as long as the first connector 811 of the feeder 61 is connected to the second connector 812, the polarity "correct relative to the first conductive strip 44A and the second conductive strip 44B provided in the first wiring duct 41" can be accepted to apply a DC voltage, thereby reducing the possibility of "wrong construction at the construction site".

(2.4) Adapter As shown in FIG. 10 , the pipe trough system 100 supplies power to the electrical equipment 20 via the power receiving device 9 “connected to the first wiring pipe trough 41 and the second wiring pipe trough 42”.

The power receiving device 9, as shown in FIG. 11 , includes an adapter 9A. The adapter 9A has: a connector that can be connected to the connector 201 of the "wire configured in the electrical device 20". For example, when the first wiring duct 41 receives the connection adapter 9A, the adapter 9A receives the supply of DC power through the first conductive strip 44A and the second conductive strip 44B of the first wiring duct 41. Then, when the connector of the adapter 9A receives the connector 201 connected to the "wire configured in the electrical device 20", the DC power is supplied to the electrical device 20 from the first wiring duct 41 through the adapter 9A. The adapter 9A can be installed in the first wiring duct 41 at any position in the area where the groove portion 4310 is provided, and can be electrically connected to the conductive strip 44.

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

The housing 91 is in the shape of a cube. The housing 91 has a first insertion port 911 and a second insertion port 912. The first insertion port 911 is used as an insertion port for the USB Type-A connector of the connector 201 (see FIG. 10 ). The second insertion port 912 is used as an insertion port for the USB Type-C connector of the connector 201. That is, the specification of the first insertion port 911 is different from that of the second insertion port 912. The size of the first insertion port 911 is different from that of the second insertion port 912.

When the adapter 9A is installed in the first wiring duct 41, the first insertion port 911 and the second insertion port 912 are provided on the surface "facing the opposite side of the first wiring duct 41" (connector mounting surface 901). When the adapter 9A is installed in the first wiring duct 41, the first insertion port 911 and the second insertion port 912 are arranged side by side in the vertical direction.

The two power receiving terminals protrude from the housing 91 toward the "side opposite to the connector mounting surface 901". The front ends of the two power receiving terminals are bent in opposite directions. When the adapter 9A is installed in the first wiring duct 41, one of the two power receiving terminals is connected to the first conductive strip 44A on the positive side, and the other is connected to the second conductive strip 44B on the negative side.

The adapter 9A further has a voltage converter. The voltage converter converts the "DC voltage received by the two power receiving terminals" into a DC voltage of a desired voltage value. The DC voltage "after the voltage value is converted by the voltage converter" is output from the first plug-in port 911 and the second plug-in port 912. For the electrical device 20 (refer to Figure 10), the DC voltage is applied by a cable including a "connector 201 connected to the first plug-in port 911 or the second plug-in port 912".

(2.5) Partition section As shown in FIG. 4 , the partition section 10 includes a partition 101 and a partition fixing section 102 for fixing the partition 101 to the first fixing section 1. In addition, the "partition" is also called a partition plate or a partition screen.

As shown in Fig. 1 and Fig. 2, the partition fixing part 102 is in the shape of a strip that is long in the left-right direction. The partition fixing part 102 is arranged on the first fixing part 1. Moreover, when the partition fixing part 102 is viewed from the right side, as shown in Fig. 4, it is in the shape of a U with an opening formed on the lower side. The partition fixing part 102 is arranged on the first fixing part 1 in such a way that the opening of the U-shape covers the top of the first fixing part 1. The partition fixing part 102 is fixed to the first fixing part 1 from the upper side by screws or the like.

The partition fixing portion 102 has a clamping portion 103 extending in the left-right direction at the center in the front-rear direction. The clamping portion 103 has a clamping groove 1031 extending from the left end to the right end of the clamping portion 103, for example, to clamp the flat partition 101 in the thickness direction.

The partition 101 is light-transmissive. The material of the partition 101 is, for example, acrylic resin. The thickness direction of the partition 101 is parallel to the front-rear direction.

Thus, the space above the top plate 31 is divided into a front space and a rear space by the partition 101. Some people (hereinafter referred to as "the first person") sit in front of the table 3, and others (hereinafter referred to as "the second person") sit behind the table 3. Since the space between the first person and the second person is separated by the partition 101, the possibility of "droplet infection between the first person and the second person" can be reduced.

(3) Variations The above implementation is only one of the various implementations of the present invention. The above implementation can be modified in various ways according to the design, etc., as long as the purpose of the present invention can be achieved.

The following are examples of modifications of the above-mentioned implementation modes. The modifications described below can be appropriately combined and applied.

For example, the pipe trough system 100 is not limited to having two wiring pipe troughs 4, and may have one or more than three wiring pipe troughs 4. In addition, the pipe trough system 100 is not limited to having one first fixing portion 1, and may have two or more first fixing portions 1. The pipe trough system 100 is not limited to having two second fixing portions 2, and may have one or more than three second fixing portions 2. In addition, the pipe trough system 100 is not limited to having one partition plate 101, and may have two or more partition plates 101.

The first fixing portion 1 may be installed with two or more wiring ducts 4. Furthermore, the voltages of the conductive bars 44 of the two or more wiring ducts 4 may be different. Furthermore, the specifications of the adapters 9A that can be installed in the two or more wiring ducts 4 may be different.

One wiring duct 4 may be fixed to more than two first fixing portions 1 .

The second fixing portion 2 is not limited to being fixed to the top plate 31 by the clamping portion 28. The second fixing portion 2 may also be fixed to the top plate 31 by, for example, screws.

The first fixing portion 1 is not limited to accommodating the wiring duct 4. The first fixing portion 1 may support the wiring duct 4 at one or more locations. The first fixing portion 1 may support the wiring duct 4 with a cantilever beam structure or a double-end fixing beam structure.

The protrusion 72 of the connector holding portion 7 is not limited to extending to the outside of the support bar portion 23 in the direction of the right end of the top plate 31 inserted into the base 24, but may extend to the inside of the base 24 protruding outward in the support bar portion 23. In other words, the base 24 may be located below the connector portion 8 held by the front end of the protrusion 72. In this case, the vertical position of the connector holding portion 7 installed on the second fixing portion 2 can be changed in a manner that the connector portion 8 does not contact the base 24.

(Summary) As described above, the wiring duct fixture (F1) according to the first embodiment includes a first fixing portion (1), a second fixing portion (2), and a connector holding portion (7). The first fixing portion (1) is in the shape of a long strip and is installed with a wiring duct (4).
