(Embodiment 1)
(Overview)
As shown in FIG. 1, the DC duct system 100 of the present embodiment includes a DC duct 3 and a feeding member (so-called feed-in) 4.

The DC duct 3 holds the first conductive bar 32A on the positive electrode side and the second conductive bar 32B on the negative electrode side to which a DC voltage is applied. A power receiving device 5 (see FIG. 14) can be connected to the DC duct 3 at arbitrary positions in the length direction of the first conductive bar 32A and the second conductive bar 32B. The power receiving device 5 is a device that receives a DC voltage via the first conductive bar 32A and the second conductive bar 32B.

As shown in FIG. 3, the power feeding member 4 has a first contact 44A that can be connected to the first conductive bar 32A and a second contact 44B that can be connected to the second conductive bar 32B. The feeding member 4 is connected to one end of the DC duct 3 in the length direction.

A connection blocking structure (for example, a protrusion 35) is provided at the other end of the DC duct 3 in the length direction (the end opposite to the end to which the feeding member 4 is connected). The connection blocking structure (projection 35) connects the feeding member 4 to the other end of the DC duct 3 by contacting with at least a part of the feeding member 4 (for example, a projection 45 provided on the feeding member main body 42). To prevent.

As shown in FIG. 8, the power feeding member 4 has a first terminal 43A, a second terminal 43B, and a power feeding member main body 42. The first terminal 43A is electrically connected to the first contact 44A, and the electric wire W1 on the positive electrode side of the DC power supply unit PE1 (see FIG. 14) that outputs a DC voltage can be connected. The second terminal 43B is electrically connected to the second contact 44B, and the electric wire W2 on the negative electrode side of the DC power supply unit PE1 can be connected. The power feeding member main body 42 holds the first terminal 43A and the second terminal 43B. The power feeding member main body 42 is provided with polarity display units (marks M1 and M2) for displaying the polarities of the first terminal 43A and the second terminal 43B.

In the following description, the first conductive bar 32A and the second conductive bar 32B may be collectively referred to as the conductive bar 32. Further, the first contactor 44A and the second contactor 44B may be collectively referred to as a contactor 44.

The power receiving device 5 connected to the DC duct 3 includes an adapter 5A (see FIGS. 6, 11 to 14). The adapter 5A has a connector to which the connector 95 provided on the electric wire of the electric device 94 can be connected. When the adapter 5A is connected to the DC duct 3, the adapter 5A receives a DC voltage via the first conductive bar 32A and the second conductive bar 32B of the DC duct 3. Then, when the connector 95 provided on the electric wire of the electric device 94 is connected to the connector of the adapter 5A, a DC voltage is supplied from the DC duct 3 to the electric device 94 via the adapter 5A. The type of the electric device 94 is not particularly limited. As an example of the electric device 94, a computer terminal (personal computer, smartphone, tablet terminal, etc.), an accessory device of the computer terminal (monitor, speaker, microphone, etc.), a lighting device (desk light, etc.), a network camera, a sensor (temperature sensor, etc.) , Humidity sensor, illuminance sensor, etc.), game machines and air conditioning equipment (desktop fans, etc.). The power receiving device 5 is not limited to the adapter 5A, and may be the electric device 94 itself. By connecting the electric device 94, which is the power receiving device 5, to the DC duct 3, the electric device 94 can receive the DC voltage from the DC duct 3. The fact that the power receiving device 5 is connected to an arbitrary position in the length direction of the first conductive bar 32A and the second conductive bar 32B is continuous in the length direction of the first conductive bar 32A and the second conductive bar 32B. It may include being electrically connected to the first conductive bar 32A and the second conductive bar 32B in a state of being arranged at an arbitrary position in the attached mounting area.

It is possible to reduce the possibility that the polarities of the electric wires connected to the terminal 43A and the second terminal 43B are mistaken. Further, since the DC duct 3 is provided with a connection blocking structure at the other end in the longitudinal direction, it is possible to reduce the possibility that the power feeding member 4 is mistakenly connected to the other end of the DC duct 3. Therefore, the first conductive bar 32A and the second conductive bar 32A and the second conductive bar 32A can be reliably connected to one end of the DC duct 3 so that the first conductive bar 32A is on the positive electrode side and the second conductive bar 32B is on the negative electrode side. A DC voltage can be applied to the conductive bar 32B. Therefore, it is possible to reduce the possibility that a DC voltage is applied to the first conductive bar 32A and the second conductive bar 32B with an erroneous polarity.

Here, the DC duct system 100 includes a DC duct 3 and a feeding member 4. In other words, the DC duct 3 is a DC duct provided (applied to) by the DC duct system 100. Further, the power feeding member 4 is a power feeding member included (applied to) in the DC duct system 100.

Thereby, in the DC duct system 100 of the present embodiment, the DC duct 3 can be fixed to the fixture via the duct fixture F1. Then, by connecting the connector 95 of the electric device 94 (or the connector of the cable connected to the electric device 94) to the adapter 5A, power can be supplied to the electric device 94 from the DC duct 3. Therefore, the wiring around the furniture is simpler than when power is supplied to the electric device 94 from the power outlet or when power is supplied to the electric device 94 from the power tap that distributes the power of the power outlet. Will be transformed. That is, it is possible to reduce the possibility that the electric wires are messed up around the furniture, such as the electric wires of the electric device 94 being mixed, and the electric wires around the furniture are simplified.

Here, the fixture to which the DC duct system 100 is fixed is a general term for furniture and fixtures used in a house or a non-house. An example of furniture is a desk, table, workbench, etc. used as a table on which objects are placed. Another example of furniture is shelves, boxes, dressers, beds, whiteboards, screens, dividers and chaise lounges. In the following, a case where the DC duct system 100 is fixed to a desk 7 as a fixture and used will be described as an example.

Further, the DC duct system 100 of the present embodiment includes a partition fixing structure S1 (see FIGS. 11 and 12) capable of fixing the partition 6 (see FIG. 9). A "partition" is also referred to as a partition or tsuitate. The partition system 200 includes a DC duct system 100 and a partition 6. In the present embodiment, the number of partitions 6 included in one partition system 200 is three.

Hereinafter, a procedure for fixing the DC duct system 100 to the desk 7 using the clamp mechanism 23 will be described. As shown in FIG. 9, a part (left end or right end) of the top plate 71 of the desk 7 is inserted into the wire hole 220. As a result, a part (left end or right end) of the top plate 71 is arranged between the support column portion 22 and the movable portion 231. The operator turns the operation unit 233 to move the movable unit 231 upward. As a result, a part (left end or right end) of the top plate 71 is sandwiched between the support column portion 22 and the movable portion 231. The DC duct system 100 is fixed to the desk 7 by sandwiching the left end and the right end of the top plate 71 by using the respective clamp mechanisms 23 of the two second fixing portions 2.

Further, due to the presence of the support column portion 22, a gap G1 (see FIG. 9) is secured between the two first fixing portions 1 of the DC duct system 100 and the top plate 71 of the desk 7. That is, a gap G1 is secured between the two duct main bodies 31 fixed to the two first fixing portions 1 and the top plate 71. In other words, the second fixing portion 2 (fixing member) includes a support column portion 22 that supports the two duct main bodies 31 with a gap G1 between the two duct main bodies 31 and the desk 7 (furniture).

In the present disclosure, the fact that there is a gap between the duct main body 31 and the desk 7 (furniture) means that a predetermined member (a part of the first fixing portion 1) is provided between the duct main body 31 and the desk 7 as in the present embodiment. ), And there is a gap G1 extending from the lower surface of the predetermined member to the upper surface of the desk 7. Further, in the present disclosure, the gap between the duct main body 31 and the desk 7 (furniture) includes a case where there is a gap extending from the lower surface of the duct main body 31 to the upper surface of the desk 7.

By passing through the gap G1, documents and other items can be delivered across the partition 6. Further, an opening may be provided in a portion of the top plate 71 of the desk 7 below the first fixing portion 1. The opening is configured to draw out an electric wire for supplying AC power from under the top plate 71. The user can reach into the gap G1 and pull out the wire through the opening.

(5) DC Duct As shown in FIGS. 1 to 4, 6 and 13, each of the two DC ducts 3 has a duct main body 31 and two conductive bars 32 (first conductive bar 32A and second conductive bar 32). Bar 32B) and. The duct body 31 includes a first rail 311 made of metal and a second rail 312 made of two synthetic resins.

The two DC ducts 3 correspond one-to-one with the two first fixing portions 1. Each DC duct 3 is housed in the storage groove 130 of the corresponding first fixing portion 1. Therefore, the two DC ducts 3 are arranged on both sides in the front-rear direction with the partition 6 in between. That is, the DC duct system 100 includes a plurality (two) of DC ducts 3, and the plurality of DC ducts 3 include two DC ducts 3 arranged on both sides of the partition 6. Thereby, in the present embodiment, electric power can be supplied to the electric devices 94 arranged on both sides of the partition 6.

Further, in the above two DC ducts 3, a predetermined number of DC ducts 3 are fixed along the horizontal plane with a plurality of DC ducts 3 fixed to the first fixing portion 1 and the second fixing portion 2 fixed to the fixture (desk 7). They are located on opposite sides of each other in the direction (front-back direction). In other words, the two DC ducts 3 are arranged in the front-rear direction.

The shape of the first rail 311 is a square cylinder. The axial direction (length direction) of the first rail 311 is along the left-right direction. The first rail 311 includes a recess 3110. The recess 3110 is formed along the length direction (left-right direction) of the duct main body 31. More specifically, the recess 3110 is formed over both ends of the duct body 31 in the length direction. Two conductive bars 32 are housed in the recess 3110.

The recess 3110 is open on the surface along the surface of the partition 6. More specifically, in each of the two DC ducts 3, the recess 3110 is opened on the surface (outward surface) opposite to the surface on which the two DC ducts 3 face each other. In each of the two DC ducts 3, the surface on which the recess 3110 opens is referred to as the front surface. The end portion of each of the two DC ducts 3 that is the right end when viewed from the front side is referred to as the first end 31A, and the end portion that is the left end is referred to as the second end 31B.

As shown in FIGS. 1, 2A, 2B, and 13, the first rail 311 further includes two fitting portions 3111 and two mounting grooves 3112.

Each of the two fitting portions 3111 is a groove. The two fitting portions 3111 are provided on the inner surface of the recess 3110. The two fitting portions 3111 are formed along the length direction (left-right direction) of the duct main body 31. More specifically, the two fitting portions 3111 are formed over the entire length of the duct body 31. The two fitting portions 3111 are fitted to the adapter 5A. As a result, the adapter 5A is attached to the DC duct 3. That is, the duct main body 31 includes an adapter mounting portion (two fitting portions 3111) for mounting the adapter 5A. The procedure for attaching the adapter 5A to the DC duct 3 will be described later.

The two mounting grooves 3112 are provided on the inner surface of the recess 3110. Of the two fitting portions 3111 and the two mounting grooves 3112, the two fitting portions 3111 are provided closer to the opening of the recess 3110. The two mounting grooves 3112 are formed along the length direction (left-right direction) of the duct main body 31. More specifically, the two mounting grooves 3112 are formed over the entire length of the duct body 31.

The two mounting grooves 3112 correspond one-to-one with the two second rails 312. A corresponding second rail 312 is fitted in each mounting groove 3112. As a result, two second rails 312 are attached to the first rail 311. The first rail 311 has two protrusions 3113 (see FIG. 13) for suppressing the falling off of the two second rails 312.

Further, the first rail 311 further has a regulation unit 3114 (see FIG. 13). The regulating portion 3114 is a protrusion. The regulation unit 3114 (see FIG. 13) is provided at the lower part of the first rail 311. The regulating portion 3114 is inserted into the regulating portion 55 (recessed portion) of the adapter 5A.

Each of the two second rails 312 has a length in the left-right direction. The second rail 312 is made of a synthetic resin such as PTC (Polyvinyl Chloride). The shape of the second rail 312 in the cross section orthogonal to the left-right direction is U-shaped. The second rail 312 holds a conductive bar 32 (first conductive bar 32A or second conductive bar 32B) inside the second rail 312.

Each of the two conductive bars 32 (first conductive bar 32A or second conductive bar 32B) has a length in the left-right direction. Each of the first conductive bar 32A and the second conductive bar 32B is provided from the right end to the left end of the duct main body 31. Each of the first conductive bar 32A and the second conductive bar 32B is electrically connected to the corresponding electric wires W1 and W2 (see FIGS. 7, 8 and 10A) via the feeding member 4. In the present embodiment, the first conductive bar 32A is electrically connected to the electric wire W1 on the positive side, the second conductive bar 32B is electrically connected to the electric wire W2 on the negative side, and the first conductive bar 32A and the first conductive bar 32B. DC power is supplied to the two conductive bars 32B.

The duct main body 31 is provided with fitting portions for fitting with the power feeding member 4 at the first end (for example, the right end) 31A and the second end (for example, the left end) 31B in the longitudinal direction. Therefore, the duct main body 31 is provided with a connection blocking structure that restricts the end portion to which the power feeding member 4 can be attached to either the first end 31A or the second end 31B. In this embodiment, the connection blocking structure includes a protrusion 35 provided on the inner surface of the duct body 31. The protrusion 35 is provided at the lower part of the rear wall in the recess 3110 of the duct main body 31. The protrusion 35 is provided over the entire length of the duct main body 31 in the longitudinal direction (left-right direction). That is, the DC duct 3 is provided with a connection blocking structure (projection 35) as a whole in the length direction (left-right direction) of the first conductive bar 32A and the second conductive bar 32B.

As a result, as shown in FIGS. 2A and 2B, when the DC duct 3 is viewed from the length direction, the fitting portion of the DC duct 3 to which the feeding member 4 fits (first end 31A and second end 31B). ) Is asymmetrical with respect to the center line L1 of the DC duct 3 in a predetermined direction. The predetermined direction is a direction (vertical direction) orthogonal to the mounting direction (front-back direction) and the length direction (left-right direction) of the power receiving device 5 (adapter 5A or the like) to the DC duct 3.

The duct main body 31 is provided with a protrusion 35 as a connection blocking structure, and the protrusion 35 is provided over the entire length of the duct main body 31. Therefore, when the first feeding member 4A connectable to the first end 31A is to be connected to the second end 31B, the feeding member main body 42 of the first feeding member 4A interferes with the protrusion 35 on the second end 31B. The connection of the first feeding member 4A to the second end 31B is blocked. Further, when the second feeding member 4B connectable to the second end 31B is to be connected to the first end 31A, the feeding member main body 42 of the second feeding member 4B interferes with the protrusion 35 on the first end 31A. The connection of the second feeding member 4B to the first end 31A is blocked. That is, the connection blocking structure (projection 35) blocks the connection of the first feeding member 4A to the second end 31B, and blocks the connection of the second feeding member 4B to the first end 31A. Therefore, the feeding member 4 can prevent the feeding member 4 from being connected to the end of the first end 31A and the second end 31B opposite to the end to which the connection is permitted, and the feeding member 4 can supply power. There is an advantage that the first contactor 44A and the second contactor 44B of the member 4 are securely connected to the first conductive bar 32A and the second conductive bar 32B, respectively.

Further, since the duct main body 31 is provided with a protrusion 35 which is a connection blocking structure as a whole in the length direction, the duct main body 31 is cut to an arbitrary length according to the dimensions of the fixture to which the DC duct 3 is attached. Even in this case, the shapes of the first end 31A and the second end 31B of the duct main body 31 can be formed into the same shape.

(6) Feeding member and end cap As shown in FIG. 6, the two feeding members 4 correspond one-to-one with the two DC ducts 3. The two end caps CP1 have a one-to-one correspondence with the two DC ducts 3. A corresponding feeding member 4 is attached to one of the first end 31A and the second end 31B of each DC duct 3, and the corresponding end cap CP1 is attached to the other.

As described above, the power feeding member 4 is configured so that it can be attached to only one of the first end 31A and the second end 31B of the DC duct 3. That is, the feeding member 4 includes a first feeding member 4A connected to the first end 31A of the duct main body 31 and a second feeding member 4B connected to the second end 31B of the duct main body 31. Only one of the first feeding member 4A and the second feeding member 4B needs to be connected to one DC duct 3.

The power feeding member 4 (first feeding member 4A and second feeding member 4B) corresponds to the two conductive bars 32 (first conductive bar 32A and second conductive bar 32B) of the DC duct 3, respectively, of electric wires W1 and W2 (FIG. 8 and FIG. 10A) for electrical connection. That is, the first conductive bar 32A and the second conductive bar 32B are electrically connected to the corresponding electric wires W1 and W2 via the feeding member 4. Hereinafter, the configuration of the feeding member 4 will be described with reference to FIG. 8 by taking the second feeding member 4B as an example. Since the configuration of the first feeding member 4A is the same as that of the second feeding member 4B except for the

protrusions

45A and 45B, the description of the first feeding member 4A will be omitted.

The feeding member 4 (second feeding member 4B) includes an outer box 41, a feeding member main body 42, and two terminals 43.

The shape of the outer box 41 is a rectangular parallelepiped. The outer box 41 houses the power feeding member main body 42. The power feeding member main body 42 has a first block 421 and a second block 422. By connecting the first block 421 and the second block 422, one box-shaped member (feeding member main body 42) is formed.

The power feeding member main body 42 houses two terminals 43. Further, the power feeding member main body 42 has two entry holes 423 into which the two electric wires W1 and W2 are inserted. The two entry holes 423 are provided in the first block 421.

The two terminals 43 include a first terminal 43A connected to the electric wire W1 on the positive electrode side of the DC power supply and a second terminal 43B connected to the electric wire W2 on the negative electrode side of the DC power supply. A first contact 44A is provided integrally with the first terminal 43A, and a second contact 44B is provided integrally with the second terminal 43B. Each of the two terminals 43 (first terminal 43A and second terminal 43B) has a spring 431 and a terminal portion 432 (see FIG. 10B). The set of the spring 431 and the terminal portion 432 constitutes a quick connection terminal. That is, each of the two terminals 43 has a quick-connect terminal.

The spring 431 is formed by bending a metal plate or the like. The terminal portion 432 is made of a metal plate and is formed in a plate shape. The terminal portion 432 faces the spring 431. The two terminals 43 (first terminal 43A and second terminal 43B) have a one-to-one correspondence with the two conductive bars 32 (first conductive bar 32A and second conductive bar 32B). The terminal portion 432 of each terminal 43 is electrically connected to the corresponding conductive bar 32 (first conductive bar 32A and second conductive bar 32B). That is, the first terminal 43A includes a first contact 44A made of a terminal portion 432, and the second terminal 43B includes a second contact 44B made of a terminal portion 432.

As shown in FIGS. 10A and 10B, each of the electric wires W1 and W2 inserted into the inside of the feeding member main body 42 through the entry hole 423 is sandwiched between the spring 431 and the terminal portion 432. As a result, each of the electric wires W1 and W2 is electrically connected to the first terminal 43A and the second terminal 43B, respectively, and is held between the spring 431 and the terminal portion 432, respectively.

As described above, the power feeding member 4 is configured to be connectable to only one of the first end 31A and the second end 31B of the DC duct 3.

In order to prevent the power feeding member 4 from connecting to the end of the first end 31A and the second end 31B of the DC duct 3 opposite to the connectable end to the power feeding member main body 42 of the feeding member 4. Is provided with a protrusion 45 that interferes with the protrusion 35 of the DC duct 3. In the following, the protrusion 45 provided on the feeding member main body 42 of the first feeding member 4A may be referred to as a protrusion 45A, and the protrusion 45 provided on the feeding member main body 42 of the second feeding member 4B may be referred to as a protrusion 45B.

In the feeding member main body 42 of the second feeding member 4B that can be connected to the second end 31B of the DC duct 3, the protrusion 45B is located at a position where the feeding member main body 42 interferes with the protrusion 35 when the feeding member main body 42 is inserted into the first end 31A (FIG. 4) is provided. Since the protrusion 45B is provided on the side opposite to the protrusion 35 in the vertical direction (upper side in a state of being connected to the second end 31B of the DC duct 3), the feeding member main body 42 is inserted into the second end 31B. In that case, it does not interfere with the protrusion 35. Therefore, the second power feeding member 4B is configured to be connectable only to the second end 31B of the DC duct 3, and can be prevented from being attached to the side opposite to the side where the connection is permitted to the DC duct 3. ..

Further, in the feeding member main body 42 of the first feeding member 4A that can be connected to the first end 31A of the DC duct 3, the protrusion 45A is located at a position where the feeding member main body 42 interferes with the protrusion 35 when the feeding member main body 42 is inserted into the second end 31B. (See FIG. 1) is provided. Since the protrusion 45A is provided on the side opposite to the protrusion 35 in the vertical direction (upper side in a state of being connected to the first end 31A of the DC duct 3), the feeding member main body 42 is inserted into the first end 31A. In that case, it does not interfere with the protrusion 35. Therefore, the first power feeding member 4A is configured to be connectable only to the first end 31A of the DC duct 3, and can be prevented from being attached to the side opposite to the side where the connection is permitted to the DC duct 3. ..

Further, the power feeding member main body 42 is provided with marks M1 and M2 as polarity display units indicating the polarities of the electric wires W1 and W2 connected to the two terminals 43 (first terminal 43A and second terminal 43B). The marks M1 and M2 are provided on the surface of the feeding member main body 42 in the vicinity of the entry hole 423 corresponding to the first terminal 43A and the second terminal 43B, respectively. The marks M1 and M2 are provided on the power feeding member main body 42 by an appropriate method such as resin molding, engraving, printing, painting, and sticking a sticker or a name plate on which the marks M1 and M2 are printed. Since the polarity display units (marks M1 and M2) are provided on the surface of the power feeding member main body 42, polarity errors are less likely to occur when the electric wires W1 and W2 are connected to the first terminal 43A and the second terminal 43B, respectively. It has the advantage of becoming.

(7) Partition Hereinafter, the partition 6 will be described with reference to FIG. 9. Hereinafter, the three partitions 6 may be distinguished and referred to as

partitions

6A, 6B, and 6C, respectively. The configurations common to the three partitions 6 are designated by the same reference numerals, and duplicate description will be omitted as appropriate. Of the three partitions 6, partition 6A is located on the far right, partition 6C is located on the far left, and partition 6B is located between partition 6A and partition 6C.

Partitions 6A to 6C have a plate-shaped partition body 61 having translucency. The material of the partition 6 is, for example, acrylic resin. A fitting projection inserted into the partition fixing structure S1 (through hole) is provided at the lower portion of the partition main body 61.

The fitting protrusions of the three partitions 6 are inserted into the corresponding partition fixing structures S1 (through holes). As a result, each partition 6 is fixed to the DC duct system 100. That is, the partition fixing structure S1 is a structure that fits with the partition 6. Further, each partition 6 can be removed from the DC duct system 100 by removing the fitting protrusion from the partition fixing structure S1. That is, the partition fixing structure S1 fixes the partition 6 detachably.

(8) Adapter As shown in FIGS. 9 and 10A, one first fixing portion 1 is arranged on both sides in the front-rear direction with the partition 6 interposed therebetween, and a DC duct 3 is housed in each first fixing portion 1. Has been done. An adapter 5A can be attached to each of these two DC ducts 3.

As shown in FIGS. 11 to 13, the adapter 5A has a housing 51, a release operation unit 52, a mounting projection 53, two power receiving terminals 54, and a spring housed in the housing 51.

The shape of the housing 51 is a rectangular parallelepiped. The housing 51 has a first insertion port 511 and a second insertion port 512. The first outlet 511 is an outlet for a USB Type-A plug as a connector 95 (see FIG. 14). The second outlet 512 is an outlet for a USB Type-C plug as a connector 95. That is, the standard of the first outlet 511 is different from that of the second outlet 512. The size of the first outlet 511 is different from that of the second outlet 512.

The first insertion port 511 and the second insertion port 512 are provided on the surface facing the opposite side of the DC duct 3 (connector mounting surface 501) when the adapter 5A is attached to the DC duct 3. The first outlet 511 and the second outlet 512 are arranged one above the other when the adapter 5A is attached to the DC duct 3.

The release operation unit 52 is held in the housing 51. The release operation unit 52 can move in a predetermined direction by applying a force. The return force of the spring housed in the housing 51 acts on the release operation unit 52. Therefore, when no force is applied to the release operation unit 52, the tip portion (claw portion 520) of the release operation unit 52 protrudes from the housing 51 to the side opposite to the connector mounting surface 501 side. ..

The mounting protrusion 53 includes a shaft portion 531 and two ribs 532. The shaft portion 531 protrudes from the housing 51 on the side opposite to the connector mounting surface 501 side. The two ribs 532 project from the side surface of the shaft portion 531. The two ribs 532 project in opposite directions.

The two power receiving terminals 54 project from the housing 51 to the side opposite to the connector mounting surface 501 side. The tip of each of the two power receiving terminals 54 is bent.

The adapter 5A has a regulation unit 55. The restricting portion 55 is a recess formed on the surface of the adapter 5A (the surface facing the DC duct 3). When the adapter 5A is attached to the duct main body 31, the restricting portion 3114 (projection) of the duct main body 31 is inserted into the restricting portion 55. If the orientation of the adapter 5A is incorrect (that is, the orientation shown in FIG. 11 is upside down), the restricting unit 3114 interferes with the adapter 5A, so that the adapter 5A can be attached to the duct body 31. Can not. That is, the regulating

portions

55 and 3114 regulate the orientation of the adapter 5A when the adapter 5A is attached to the duct main body 31. As a result, of the two power receiving terminals 54, the power receiving terminal 54 on the positive electrode side is connected to the first conductive bar 32A on the positive electrode side, and the power receiving terminal 54 on the negative electrode side is connected to the second conductive bar 32B on the negative electrode side.

The adapter 5A further has a voltage converter. The voltage converter converts the DC voltage received by the two power receiving terminals 54 into a DC voltage having a desired voltage value. A DC voltage whose voltage value has been converted by a voltage converter is output from the first insertion port 511 and the second insertion port 512. A DC voltage is applied to the electrical device 94 (see FIG. 14) via a cable including a connector 95 connected to a first outlet 511 or a second outlet 512.

The procedure for attaching the adapter 5A to the DC duct 3 will be described below.

In the orientation of the housing 51 shown in FIGS. 12 and 13, the two ribs 532 are arranged in the vertical direction.

First, as shown in FIG. 11, the operator holds the adapter 5A so that the direction in which the two ribs 532 are arranged is along the length direction (left-right direction) of the duct main body 31. In this state, the mounting projection 53 can be inserted into the recess 3110 of the duct body 31 without the two ribs 532 interfering with the duct body 31. The release operation unit 52 moves toward the connector mounting surface 501 side due to the contact pressure with the first fixing unit 1.

After inserting the mounting protrusion 53 into the recess 3110 as shown in FIG. 11, the operator rotates the adapter 5A 90 degrees clockwise as shown in FIGS. 12 and 13. Then, as shown in FIG. 13, the two ribs 532 are inserted into the two fitting portions 3111. As a result, the movement of the adapter 5A in the front-rear direction is restricted. Further, as shown in FIG. 12, since the rotation of the housing 51 is restricted by inserting the claw portion 520 of the release operation portion 52 into the recess 3110 of the duct main body 31, the adapter 5A is attached to the DC duct 3. It is held in the state of being. Further, the two power receiving terminals 54 come into contact with the corresponding conductive bars 32 (first conductive bar 32A and second conductive bar 32B), respectively, thereby being electrically connected to the corresponding conductive bars 32.

By the above procedure, the adapter 5A is attached to the DC duct 3. The adapter 5A can be attached to the DC duct 3 at an arbitrary position in the area (attachment area) where the recess 3110 is provided, and can be electrically connected to the conductive bar 32.

In this embodiment, there is no configuration for restricting the movement of the adapter 5A attached to the DC duct 3 in the left-right direction. Therefore, the adapter 5A can move in the left-right direction while being attached to the DC duct 3. However, in order to suppress the wear of the two power receiving terminals 54 due to the movement of the adapter 5A in the left-right direction, the DC duct system 100 has a configuration that restricts the movement of the adapter 5A attached to the DC duct 3 in the left-right direction. You may be prepared.

Next, the procedure for removing the adapter 5A from the DC duct 3 will be described. When the operator applies a force toward the connector mounting surface 501 to the release operation unit 52, the release operation unit 52 moves and the claw portion 520 comes out of the recess 3110. As a result, the restriction on the rotation of the housing 51 is lifted. When the operator rotates the housing 51 counterclockwise by 90 degrees, the two ribs 532 come out from the two fitting portions 3111. By the above procedure, the adapter 5A is removed from the DC duct 3.

(9) Power Supply System Next, with reference to FIG. 14, an example of the configuration of a system (including the DC duct system 100) that supplies power to the electric device 94 will be described.

A switching hub 92 and a splitter 93 are provided in the facility where the electric device 94 is used. The switching hub 92 is electrically connected to the AC power supply 91. The AC power supply 91 supplies AC power to the switching hub 92. The AC power supply 91 is, for example, a commercial power supply or a distributed power supply.

The switching hub 92 is a PoE switching hub compatible with PoE (Power over Ethernet), and is provided with a DC power supply unit 921. The DC power supply unit 921 converts the AC voltage input from the AC power supply 91 into a DC voltage having a predetermined voltage value, and outputs the AC voltage to the splitter 93. The switching hub 92 is electrically connected to the splitter 93 via a LAN (Local Area Network) cable. Further, the switching hub 92 may be electrically connected to a device compatible with PoE. Devices compatible with PoE are, for example, computer terminals, network cameras, IP (Internet Protocol) telephones, wireless access points, and the like. The switching hub 92 can exchange a PoE signal including data and electric power (DC power) with a device electrically connected to the switching hub 92.

The splitter 93 is a PoE splitter compatible with PoE and includes a DC power supply unit 931. The DC power supply unit 931 converts the DC voltage input from the switching hub 92 into a DC voltage having a predetermined voltage value, and outputs the DC voltage to the DC duct 3. The splitter 93 separates the PoE signal received from the switching hub 92 into data and electric power (DC electric power). The splitter 93 supplies the electric power separated from the PoE signal to a device that does not support PoE. As an example, the splitter 93 supplies the power separated from the PoE signal to one or more electrical devices 94 that do not support PoE via the DC duct system 100.

Further, the splitter 93 transmits a data signal including data separated from the PoE signal to a device that does not support PoE.

Here, in the present embodiment, the DC power supply unit 921 of the switching hub 92 and the DC power supply unit 931 of the splitter 93 convert the AC voltage input from the AC power supply 91 into a DC voltage and output it to the power supply member 4. The power supply unit PE1 is configured.

The DC power output terminal of the splitter 93 is electrically connected to the first end of each of the two electric wires W1 and W2. One DC duct 3 of the two DC ducts 3 corresponds to two electric wires W1 and W2 of each of the two electric wires W1 and W2, and the other DC duct 3 corresponds to the remaining two electric wires W1. , W2. In the following, one DC duct 3, two electric wires W1 and W2 corresponding to the DC duct 3, and one feeding member 4 will be described.

The two electric wires W1 and W2 are an electric wire W1 on the positive electrode side and an electric wire W2 on the negative electrode side. The two electric wires W1 and W2 have a one-to-one correspondence with two entry holes 423 (see FIG. 8) provided in the power feeding member 4. Further, the two electric wires W1 and W2 correspond one-to-one with the first conductive bar 32A and the second conductive bar 32B of the DC duct 3. The second end of the electric wire W1 on the positive electrode side is inserted into the corresponding entry hole 423 and connected to the first terminal 43A, and is electrically connected to the first conductive bar 32A via the first terminal 43A. The second end of the electric wire W2 on the negative electrode side is inserted into the corresponding entry hole 423 and connected to the second terminal 43B, and is electrically connected to the second conductive bar 32B via the second terminal 43B. One or more adapters 5A can be connected to the DC duct 3, and one or more electrical devices 94 can be electrically connected to the first conductive bar 32A and the second conductive bar 32B via the adapter 5A. be.

From the above, each electric device 94 receives the electric power supplied from the DC power supply unit 931 via the electric wires W1 and W2 (that is, the DC power output by the DC power supply unit 931) via the conductive bar 32 and the adapter 5A. be able to. The user can use the electrical equipment 94 on or around the desk 7 (see FIG. 9).

The DC voltage (voltage between the two conductive bars 32) received by the adapter 5A from the two conductive bars 32 is preferably 60 V or less. In this case, there is an advantage that a qualification such as an electrician is not required when installing the adapter 5A. Therefore, the power supply can be easily secured as compared with the case where the AC100V outlet is relocated or newly installed.

It is more preferable that the DC voltage received by the adapter 5A from the two conductive bars 32 (that is, the DC voltage output by the DC power supply unit 931) is 24 V or less. Further, it is also preferable that the DC voltage received by the adapter 5A from the two conductive bars 32 is 48 V or less.

As an example, the DC voltage of the PoE signal output from the DC power supply unit 921 of the switching hub 92 is 48V. The DC power supply unit 931 of the splitter 93 has a function of lowering the DC voltage of the PoE signal received from the switching hub 92, and the DC voltage output from the DC power supply unit 931 of the splitter 93 is 24V as an example. The adapter 5A receives the DC voltage output from the splitter 93 and outputs a DC voltage of 24 V or less to the electric device 94.

By setting the voltage between the two conductive bars 32 of the DC duct 3 to 60 V or less (for example, 24 V), it is possible to reduce the possibility of electric shock when the user comes into contact with the conductive bar 32. Therefore, it is not necessary to provide the cover on the DC duct 3, and there is an advantage that the work of attaching and detaching the cover to the DC duct 3 does not take time and effort in the work of attaching the adapter 5A to the DC duct 3.

Although the configuration example of the system for supplying electric power to the electric device 94 has been described above, instead of this system, for example, the electric wires W1 and W2 are connected to a commercial power source via the AC adapter 96 (see FIG. 7). You may try to connect to the outlet of.

(10) Advantages Since the DC duct 3 of the first embodiment has a connection blocking structure, the feeding member 4 (the first feeding member 4A and the second feeding member 4B) has the first end 31A and the first feeding member 3 of the DC duct 3. Of the two ends 31B, only the predetermined end can be connected. Therefore, in a state where the first feeding member 4A and the second feeding member 4B are connected to the DC duct 3, the first contact 44A on the positive electrode side is connected to the first conductive bar 32A on the positive electrode side, and the second contact on the negative electrode side. The child 44B is connected to the second conductive bar 32B on the negative electrode side. As a result, when the first feeding member 4A and the second feeding member 4B are connected to the DC duct 3, the first contactor 44A on the positive electrode side is erroneously connected to the second conductive bar 32B on the negative electrode side, and the second on the negative electrode side. The possibility that the two contacts 44B are erroneously connected to the first conductive bar 32A on the positive electrode side can be reduced.

The power supply member main body 42 of the power supply member 4 (first power supply member 4A and second power supply member 4B) has a polarity display unit (mark) indicating the polarity of the electric wire connected to the first terminal 43A and the second terminal 43B, respectively. Since M1 and M2) are provided, it is possible to reduce the possibility that the polarities of the electric wires are mistakenly connected when the electric wires are connected to the first terminal 43A and the second terminal 43B. Therefore, it is possible to reduce the possibility that a DC voltage is applied to the first conductive bar 32A and the second conductive bar 32B of the DC duct 3 with an erroneous polarity.

(Variation example of Embodiment 1)
Hereinafter, modified examples of the first embodiment are listed. The following modifications may be realized by combining them as appropriate.

(Modification 1)
The fixture to which the DC duct system 100 of the first embodiment is applied is not limited to the desk 7 in which a person sits on the seats placed on both sides, and may be the desk 7C as shown in FIG.

The desk 7C is a desk on which the user is supposed to be seated only in front of the desk 7C, and is referred to as a counter desk, for example. The desk 7C includes a desk body 70, a duct fixture F2 for fixing the DC duct 3, and a back panel 74. The duct fixative F2 has a first fixing portion 1C and two second fixing portions 2C. The desk body 70 includes a top plate 701, a pedestal 702, and a support 703. A DC duct 3 is attached to the desk 7C. A power feeding member 4 and an adapter 5A (see FIG. 12) are attached to the DC duct 3.

(Modification 2)
The DC duct system 100 of the second modification will be described with reference to FIGS. 16 and 17.

The DC duct system 100 of the second modification is described above in that it includes a notification unit 80 (see FIG. 16) for notifying the application state of the DC voltage to the first contact 44A and the second contact 44B of the feeding member 4. It differs from the form. Here, notifying the application state of the DC voltage includes notifying whether or not a DC voltage having a predetermined polarity is applied to the first contact 44A and the second contact 44B. Further, the notification may be performed by outputting light or sound, or both light and sound, or a mobile communication terminal (for example, a smartphone) possessed by a user (for example, a worker who connects an electric wire to the power feeding member 4). It may be done by sending information to (etc.). Since the parts other than the notification unit 80 are the same as those in the above embodiment, the same components are designated by the same reference numerals and the description thereof will be omitted.

The notification unit 80 is provided, for example, on the power feeding member 4. As shown in FIG. 16, the notification unit 80 includes a resistor 82 and a light source 81 connected between the first terminal 43A and the second terminal 43B. The light source 81 is, for example, a light emitting diode, and is connected between the first contact 44A and the second contact 44B with the anode on the first contact 44A side and the cathode on the second contact 44B side. The notification unit 80 is housed inside the power feeding member main body 42 in a state where the light source 81 can be visually recognized from the outside of the feeding member main body 42 through a hole on the surface of the feeding member main body 42 (see FIG. 17). The light source 81 is not limited to the light emitting diode, and may be a solid light source such as an organic EL (Organic Electro Luminescence), an incandescent light bulb, a neon lamp, or the like.

When the positive electrode side electric wire W1 is connected to the first terminal 43A and the negative electrode side electric wire W2 is connected to the second terminal 43B, that is, an electric wire having a predetermined polarity with respect to the first terminal 43A and the second terminal 43B. When W1 and W2 are connected, the light source 81 lights up. On the other hand, when the electric wire W2 on the negative electrode side is connected to the first terminal 43A and the electric wire W1 on the positive electrode side is connected to the second terminal 43B, the light source 81 is turned off. As a result, the operator who connects the electric wires confirms whether the light source 81 is on or off, so that the electric wires W1 from the DC power supply unit PE1 are connected to the first terminal 43A and the second terminal 43B. , W2 can be easily confirmed whether or not they are connected with a predetermined polarity. Therefore, it is possible to further reduce the possibility that a DC voltage is applied to the first conductive bar 32A and the second conductive bar 32B with an erroneous polarity.

As shown in FIG. 18, in the light emitting diode which is the light source 81, the cathode is on the first contact 44A side and the anode is on the second contact 44B side, and the first contact 44A and the second contact 44B are arranged. It may be connected in between. In this case, the light source 81 is in a state where a DC voltage is applied to the first contact 44A and the second contact 44B so that the voltage of the second contact 44B is higher than the voltage of the first contact 44A. Light. That is, the light source 81 is lit in a state where the electric wire W2 on the negative electrode side is erroneously connected to the first terminal 43A and the electric wire W1 on the positive electrode side is erroneously connected to the second terminal 43B. Since 81 is lit, it can be easily confirmed that the electric wires W1 and W2 are erroneously connected. Further, when the electric wires W1 and W2 are connected to the first terminal 43A and the second terminal 43B with predetermined polarities (when no erroneous connection occurs), the light source 81 is turned off. Therefore, there is an advantage that power consumption can be suppressed.

As shown in FIG. 19, the power feeding member 4 may be provided with a first notification unit 80A and a second notification unit 80B as the notification unit 80.

The first notification unit 80A includes a resistor 82A and a light source 81A connected between the first terminal 43A and the second terminal 43B. The light source 81A is, for example, a light emitting diode, and is connected between the first contact 44A and the second contact 44B with the anode on the first contact 44A side and the cathode on the second contact 44B side. The first notification unit 80A has a light source 81A that lights up with the positive electrode side electric wire W1 connected to the first terminal 43A and the negative electrode side electric wire W2 connected to the second terminal 43B. The light source 81A of the first notification unit 80A is arranged on the surface of the power feeding member main body 42 in the vicinity of the entry hole 423 corresponding to the first terminal 43A.

The second notification unit 80B includes a resistor 82B and a light source 81B connected between the first terminal 43A and the second terminal 43B. The light source 81B is, for example, a light emitting diode, and is connected between the first contact 44A and the second contact 44B with the anode on the second contact 44B side and the cathode on the first contact 44A side. The second notification unit 80B has a light source 81B that lights up with the positive electrode side electric wire W1 connected to the second terminal 43B and the negative electrode side electric wire W2 connected to the first terminal 43A. The light source 81B of the second notification unit 80B is arranged on the surface of the power feeding member main body 42 in the vicinity of the entry hole 423 corresponding to the second terminal 43B.

As described above, when the power feeding member 4 includes the first notification unit 80A and the second notification unit 80B, it depends on which of the light source 81A of the first notification unit 80A and the light source 81B of the second notification unit 80B is lit. It is possible to confirm whether or not an incorrect connection of electric wires has occurred.

It is not essential that the notification unit 80 is provided in the power feeding member 4, and as shown in FIG. 20, the notification unit 80 may be provided in the DC duct 3. The notification unit 80 shown in FIG. 20 is configured to light up when an electric wire having a polarity different from the predetermined polarity is erroneously connected to the first terminal 43A and the second terminal 43B, but it is determined in advance. It may be configured to light up when a wire of the same polarity is connected. Further, the DC duct 3 is lit when a wire with a predetermined polarity is connected to the first terminal 43A and the second terminal 43B, and the first notification unit 80A is lit when the wire is erroneously connected. A second notification unit 80B may be provided.

Further, the adapter 5A connected to the DC duct 3 may be provided with the notification unit 80, and it can be confirmed whether or not a DC voltage having a predetermined polarity is supplied to the adapter 5A.

Further, the power receiving device connectable to the DC duct 3 may include an inspection device 9 (see FIG. 21) provided with a notification unit 80. If the inspection device 9 is connected to the DC duct 3 at the time of construction of the DC duct 3, it is confirmed whether the light source 81 provided in the notification unit 80 is on or off, and whether or not the electric wire is erroneously connected. Can be confirmed.

Further, the notification unit 80 is not limited to the one that notifies the application state of the DC voltage to the first contact 44A and the second contact 44B by light, but may notify by sound. The notification unit 80 shown in FIG. 22 includes a diode 83 and a buzzer circuit 84 connected between the first terminal 43A and the second terminal 43B. In the notification unit 80, when the electric wire W1 on the positive electrode side is connected to the second terminal 43B and the electric wire W2 on the negative electrode side is connected to the first terminal 43A, a current flows through the buzzer circuit 84 and a notification sound is output. .. As a result, the operator who connects the electric wires can confirm whether or not the erroneous connection of the electric wires has occurred based on whether or not the notification unit 80 emits the notification sound. In the circuit shown in FIG. 22, a light emitting diode may be used instead of the diode 83, and the light emission of the light emitting diode and the sound emitted by the buzzer circuit 84 can be used for notification.

(Other variants)
In the above embodiment, the DC duct 3 is provided with the protrusion 35 as a connection blocking structure, but the shape and position of the protrusion 35 can be appropriately changed. Further, it is not essential that the protrusion 35 is provided as a connection blocking structure on the entire DC duct 3 in the length direction, and the connection blocking structure is provided only on the first end 31A and the second end 31B of the DC duct 3. May be good.

A part of the configuration of the DC duct system 100 may be provided independently of the other configurations. For example, the DC duct 3, the duct fixture F1, the first fixing portion 1 or the second fixing portion 2 (fixing member) may be provided independently of other configurations.

The number of individual configurations shown in the first embodiment is an example, and is not limited to the number shown in the first embodiment. For example, the DC duct system 100 is not limited to including two DC ducts 3, and may include one or more DC ducts 3. Further, the DC duct system 100 is not limited to including two first fixing portions 1, and may include one or three or more first fixing portions 1. Further, the DC duct system 100 is not limited to the provision of the two second fixing portions 2, and may include one or three or more second fixing portions 2. Further, the partition system 200 is not limited to including three partitions 6, and may include one, two, or four or more partitions 6.

The plurality of DC ducts 3 may include two or more DC ducts 3 arranged in the vertical direction. Further, the voltage of the conductive bar 32 may be different for each of the two or more DC ducts 3. Further, the standard of the adapter 5A that can be attached may be different for each of the two or more DC ducts 3. For example, by making the two or more DC ducts 3 different in the width or the depth of the recess 3110, even if the shape of the adapter 5A that can be attached is limited for each of the two or more DC ducts 3. good. Further, in the DC duct 3, the first conductive bar 32A on the positive electrode side may be arranged on the lower side, and the second conductive bar 32B on the negative electrode side may be arranged on the upper side.

One first fixing portion 1 may fix two or more DC ducts 3. Alternatively, two or more first fixing portions 1 may fix one DC duct 3.

Two or more DC ducts 3 may be connectable in each length direction (left-right direction).

As the second fixing portion 2, a plurality of standard second fixing portions 2 having different lengths of the horizontal portions 21 may be prepared. By replacing the second fixing portion 2 with another second fixing portion 2 having a different standard, the two second fixing portions 2 on both sides of the first fixing portion 1 are changed according to the length of the fixture (desk 7). The distance between each of the support columns 22 can be adjusted.

The configuration of the second fixing portion 2 is not limited to the configuration of being fixed to the fixture by the clamp mechanism 23. The second fixing portion 2 may be fixed to the fixture by, for example, screwing. Further, the first fixing portion 1 may be used in combination with the second fixing portion 2 by providing the first fixing portion 1 with a portion to be fixed to the fixture by screwing.

In the above embodiment, the supply voltage to the electric device 94 can be easily changed by replacing the adapter 5A with another adapter having a different output voltage to the connector 95.

Further, the connector 95 is not limited to the plug, and may be a jack (insertion port). The DC duct 3 may be capable of connecting both a first adapter to which a plug as a connector 95 can be connected and a second adapter to which a jack as a connector 95 can be connected. This makes it possible to handle an electrical device 94 or a cable having either a plug or a jack. The first adapter and the second adapter may have a common configuration other than the connection portion with the connector 95.

(Embodiment 2)
The DC duct system 100 of the second embodiment will be described with reference to FIG. 23. In the DC duct system 100 of the second embodiment, the same reference numerals are given to the same configurations as those of the first embodiment, and the description thereof will be omitted.

The DC duct system 100 includes a DC duct 3 and a feeding member 4C. Since the configuration of the DC duct 3 is the same as that of the first embodiment, the description thereof will be omitted. The power feeding member 4C is different from the power feeding member 4 of the first embodiment in that the first connector 46 is provided in place of the first terminal 43A and the second terminal 43B. The first connector 46 is, for example, a jack type connector. A plug-type second connector 97 provided on the electric wire W3 from a DC power source (for example, an AC adapter 96) that outputs a DC voltage can be connected to the first connector 46. With the second connector 97 connected to the first connector 46, a DC voltage is applied from the DC power supply (AC adapter 96) to the first contact 44A and the second contact 44B. The power feeding member 4C is a first power feeding member for the right end connected to the first end 31A which is the right end of the DC duct 3 and a left end connected to the second end 31B which is the left end of the DC duct 3. 2 Feeding member and. The feeding member 4C shown in FIG. 23 is a second feeding member for the left end connected to the second end 31B of the DC duct 3.

Since the DC duct 3 of the second embodiment has a connection blocking structure as in the first embodiment, the power feeding member 4C is predetermined among the first end 31A and the second end 31B of the DC duct 3. It can be connected only to the end. Therefore, in a state where the feeding member 4C is connected to the DC duct 3, the first contactor 44A on the positive electrode side is connected to the first conductive bar 32A on the positive electrode side, and the second contactor 44B on the negative electrode side is the second contactor 44B on the negative electrode side. It is connected to the conductive bar 32B. As a result, when the power feeding member 4C is connected to the DC duct 3, the first contact 44A on the positive electrode side is erroneously connected to the second conductive bar 32B on the negative electrode side, and the second contactor 44B on the negative electrode side is on the positive electrode side. The possibility of erroneous connection to the first conductive bar 32A can be reduced.

Then, in the second embodiment, the power supply member 4C and the DC power supply unit are connected by connecting the second connector 97 provided on the electric wire W3 of the AC adapter 96, which is the DC power supply unit, to the first connector 46 of the power supply member 4C. It suppresses erroneous connection when connecting. Therefore, it is possible to reduce the possibility that a DC voltage is applied to the first conductive bar 32A and the second conductive bar 32B of the DC duct 3 with an erroneous polarity.

The shapes of the first connector 46 and the second connector 97 can be changed as appropriate.

(Modified Example of Embodiment 2)
Hereinafter, modified examples of the second embodiment are listed. The following modifications may be realized by combining them as appropriate. Further, the following modifications may be realized by appropriately combining with the first embodiment.

(Modification 1)
The DC duct system 100 of the first modification will be described with reference to FIGS. 24 to 26.

The first connector 46 is not limited to that provided in the power feeding member main body 42, and as shown in FIG. 24, even if the first connector 46A is provided in the electric wire 47 led out from the feeding member main body 42 of the feeding member 4C. good.

Here, an example of a specific configuration of the power feeding member 4C will be described with reference to FIGS. 25 and 26. The power feeding member 4C shown in FIGS. 25 and 26 is the second end 31B, which is the left end of the DC duct 3, which is the first feeding member for the right end connected to the first end 31A, which is the right end of the DC duct 3. It may be the second feeding member for the left end connected to.

The feeding member 4C includes an outer box 41, a feeding member main body 42, and two contacts 44 (including the first contact 44A and the second contact 44B).

The power feeding member main body 42 has a rectangular parallelepiped shape in which the dimensions in the left-right direction are larger than the dimensions in the front-rear direction and the dimensions in the up-down direction. The power feeding member main body 42 has a first block 421 on the rear side and a second block 422 on the front side. The feeding member main body 42 is configured by connecting the first block 421 and the second block 422 with screws 425. The feeding member main body 42 accommodates two contacts 44 (including a first contact 44A and a second contact 44B). One end of the power feeding member main body 42 in the left-right direction is inserted into the inside of the DC duct 3.

The shape of the outer box 41 is a C-shaped rectangular parallelepiped when viewed from the right. The outer box 41 is attached to the feeding member main body 42 by using a screw 426 so as to cover a portion of the feeding member main body 42 exposed from the DC duct 3.

In the power feeding member main body 42, the electric wire 47 is introduced into the inside of the feeding member main body 42 from the second end portion opposite to the first end portion inserted into the DC duct 3. The electric wire 47 has two

conductors

471 and 472, the conductor 471 is connected to the first contactor 44A by welding, and the conductor 472 is connected to the second contactor 44B by welding.

The first connector 46A is connected to the electric wire 47. The first connector 46A is a two-pole type connector.

The second connector 97 provided on the electric wire W3 of the AC adapter 96 is connected to the first connector 46A. Since the first connector 46A is provided with a structure for preventing the second connector 97 from being connected with the opposite polarity, the first connector 46A is erroneously connected to the second connector 97 during on-site construction. The possibility can be reduced.

Further, the first connector 46A is connected to the power feeding member main body 42 via the electric wire 47, and the two

conductors

471 and 472 of the electric wire 47 are previously connected to the first contactor 44A and the second contactor 44B. .. Therefore, if the first connector 46A of the power feeding member 4 is connected to the second connector 97 of the AC adapter 96 at the construction site, direct current is applied to the first conductive bar 32A and the second conductive bar 32B included in the DC duct 3 with the correct polarity. Since the voltage is applied, it is possible to reduce the possibility of erroneous construction at the construction site.

Note that the first connector 46A shown in FIGS. 25 and 26 is an example and can be changed as appropriate.

(Modification 2)
The DC duct system 100 of the second modification will be described with reference to FIGS. 27 to 33.

In the first and second embodiments described above, the protrusion 35, which is a connection blocking structure, is provided on the rear surface of the DC duct 3, but the connection blocking structure is not limited to that provided on the rear surface of the DC duct 3. The connection blocking structure is provided in a portion other than the rear surface inside the DC duct 3 if the shape of the fitting portion of the DC duct 3 into which the power feeding member 4 is fitted is asymmetric with respect to the center line L1. You may.

FIG. 27 is a side view of the DC duct 3 as viewed from the right.

The DC duct 3 has a duct main body 31 and two conductive bars 32 (first conductive bar 32A and second conductive bar 32B).

The duct main body 31 includes a first rail 311 made of metal and a second rail 312 made of two synthetic resins. On the upper surface of the first rail 311, a mounting groove 3112 to which the second rail 312 is mounted is provided on the rear side, and a fitting portion 3111 is provided on the front side. Similarly, on the lower surface of the first rail 311, a mounting groove 3112 to which the second rail 312 is mounted is provided on the rear side, and a fitting portion 3111 is provided on the front side.

Each of the two mounting grooves 3112 is provided with holding

claws

3116 and 3117 for holding the second rail 312, and the holding

claws

3116 and 3117 hit the corners of the second rail 312 so that the second rail can be held. 312 is fixed to the mounting groove 3112.

The two fitting portions 3111 are grooves, and the two ribs 532 of the adapter 5A connected to the DC duct 3 are inserted into the two fitting portions 3111. Further, two

ribs

4211 and 4212 of the feeding member 4 attached to the DC duct 3 are inserted into the two fitting portions 3111. Of the two fitting portions 3111, the lower fitting portion 3111 is provided with a protrusion 3115 which is a connection blocking structure.

The feeding member 4 includes a first feeding member 4A attached to the first end 31A on the right side of the DC duct 3 and a second feeding member 4B attached to the second end 31B on the left side of the DC duct 3.

A rib 4211 projecting downward and a rib 4212 projecting upward are provided on the front side portion of the feeding member main body 42 of the first feeding member 4A in a state of being attached to the first end 31A of the DC duct 3. (See FIGS. 28 to 30). Similarly, on the front side portion of the feeding member main body 42 of the second feeding member 4B, a rib 4211 projecting downward and a rib 4212 projecting upward in a state of being attached to the second end 31B of the DC duct 3 are provided. (See FIGS. 31 to 33). Each of the first feeding member 4A and the second feeding member 4B is provided with a recess 4213 on the rear surface of the rib 4211 into which the protrusion 3115 provided in the fitting portion 3111 enters.

As a result, when the first feeding member 4A is to be attached to the second end 31B on the left side of the DC duct 3, the rib 4212 of the first feeding member 4A facing downward comes into contact with the protrusion 3115 of the fitting portion 3111. Therefore, it is possible to prevent the first feeding member 4A from being attached to the second end 31B. Further, when the second feeding member 4B is to be attached to the first end 31A on the right side of the DC duct 3, the rib 4212 of the second feeding member 4B facing downward comes into contact with the protrusion 3115 of the fitting portion 3111. Therefore, it is possible to prevent the second feeding member 4B from being attached to the first end 31A.

A DC voltage is supplied to the bar 32A and the second conductive bar 32B. Therefore, it is possible to reduce the possibility that a DC voltage is applied to the first conductive bar 32A and the second conductive bar 32B of the DC duct 3 with an erroneous polarity.
