[0047] In each of the following embodiments, the DC piping system, the DC piping and power supply components included in the DC piping system, and the power supply system of this disclosure will be described with reference to the accompanying drawings. However, the following embodiments are merely some of the various embodiments of this disclosure. The following embodiments can be modified in various ways according to design, etc., as long as the purpose of this disclosure is achieved. Furthermore, the drawings described in the following embodiments are schematic diagrams, and the ratios of the dimensions and thicknesses of each component in the drawings do not necessarily reflect the actual dimension ratios. In addition, the following embodiments (including variations) can be appropriately combined with each other to implement them.

[0048] (First Embodiment)

[0049] (Overview)

[0050] like Figure 1 As shown, the DC piping system 100 of this embodiment includes a DC piping 3 and a power supply component (so-called feed-in portion) 4.

[0051] DC conduit 3 holds the first conductive strip 32A on the positive side and the second conductive strip 32B on the negative side, where a DC voltage is to be applied. Power receiving device 5 (see...) Figure 14 The first conductive strip 32A and the second conductive strip 32B can be connected to the DC conduit 3 at any position along their length. The receiving device 5 is a device that receives DC voltage supply via the first conductive strip 32A and the second conductive strip 32B.

[0052] like Figure 3 As shown, the power supply component 4 has a first contact 44A that can be connected to a first conductive strip 32A and a second contact 44B that can be connected to a second conductive strip 32B. The power supply component 4 is connected to one end of the DC conduit 3 in the longitudinal direction.

[0053] An anti-connection structure (e.g., a protrusion 35) is provided at the other end of the DC conduit 3 in the longitudinal direction (the end opposite to the end to which the power supply member 4 is connected). The anti-connection structure (protrusion 35) contacts at least a portion of the power supply member 4 (e.g., a protrusion 45 provided on the power supply member body 42) to prevent the power supply member 4 from being connected to the other end of the DC conduit 3.

[0054] The power supply component 4 has a first terminal 43A, a second terminal 43B, and a power supply component body 42, such as Figure 8 As shown. The first terminal 43A is electrically connected to the first contact 44A and can be connected to the DC power supply section PE1 that outputs DC voltage (see Figure 44A). Figure 14The first terminal 43A and the second terminal 43B are connected to the positive electrode side of the DC power supply section PE1. The second terminal 43B is electrically connected to the second contact 44B and can be connected to the wire W2 on the negative electrode side of the DC power supply section PE1. The power supply component body 42 holds the first terminal 43A and the second terminal 43B. The power supply component body 42 is provided with polarity display portions (marked M1 and M2) that display the polarity of the first terminal 43A and the second terminal 43B.

[0055] Note that in the following description, in some cases, the first conductive strip 32A and the second conductive strip 32B may be collectively referred to as conductive strip 32. Furthermore, in some cases, the first contact 44A and the second contact 44B may be collectively referred to as contact 44.

[0056] The power receiving device 5 connected to DC conduit 3 includes adapter 5A (see...). Figure 6 and 11 (14). Adapter 5A has a connector to which connector 95, which is provided on the wires of electrical device 94, can be connected. When adapter 5A is connected to DC conduit 3, adapter 5A receives a supply of DC voltage via the first conductive bar 32A and the second conductive bar 32B of DC conduit 3. Then, when connector 95, which is provided on the wires of electrical device 94, is connected to the connector of adapter 5A, DC voltage is supplied to electrical device 94 from DC conduit 3 via adapter 5A. There are no particular limitations on the type of electrical device 94. Examples of electrical device 94 include computer terminals (personal computers, smartphones, tablet terminals, etc.), auxiliary devices for computer terminals (monitors, speakers, microphones, etc.), lighting devices (desk lamps, etc.), network cameras, sensors (temperature sensors, humidity sensors, illuminance sensors, etc.), game consoles, and air conditioning devices (desk fan lights). Note that the receiving device 5 is not limited to adapter 5A and can also be electrical device 94 itself. By connecting electrical device 94, which is the receiving device 5, to DC conduit 3, electrical device 94 can receive a supply of DC voltage from DC conduit 3. Note that the power receiving device 5 may be connected to any position along the length of the first conductive strip 32A and the second conductive strip 32B, including being electrically connected to either the first conductive strip 32A or the second conductive strip 32B, and being located at any position within a continuous mounting area along the length of the first conductive strip 32A and the second conductive strip 32B.

[0057] Because the main body 42 of the power supply component is provided with polarity indicator portions (marked M1 and M2), when the wires W1 and W2 of the DC power supply section PE1 are connected to the first terminal 43A and the second terminal 43B respectively, the possibility of incorrectly connecting the wires to the first terminal 43A and the second terminal 43B can be reduced. Furthermore, because the DC conduit 3 has an anti-connection structure at its other end in the longitudinal direction, the possibility of incorrectly connecting the power supply component 4 to the other end of the DC conduit 3 can be reduced. Therefore, the power supply component 4 can be reliably connected to one end of the DC conduit 3, and DC voltage can be applied to the first conductive strip 32A and the second conductive strip 32B, such that the first conductive strip 32A is on the positive side and the second conductive strip 32B is on the negative side. Therefore, the possibility of applying DC voltage to the first conductive strip 32A and the second conductive strip 32B with incorrect polarity can be reduced.

[0058] Here, the DC piping system 100 includes a DC pipe 3 and a power supply component 4. In other words, the DC pipe 3 is a DC pipe included in the DC piping system 100. Furthermore, the power supply component 4 is a power supply component included in the DC piping system 100.

[0059] Furthermore, the DC piping system 100 is included in the power supply system PS1 together with the DC power supply section PE1. The DC power supply section PE1 converts the AC voltage input from the AC power supply 91 into DC voltage and outputs the DC voltage to the power supply component 4.

[0060] Since the power supply system PS1 includes the aforementioned DC conduit system 100, the possibility of applying DC voltage to the first conductive bar 32A and the second conductive bar 32B with incorrect polarity can be reduced.

[0061] In addition to the DC pipe 3 described above, the DC piping system 100 of this embodiment also includes a pipe fixing device F1. Figure 9 The pipe fixing device F1 has a first fixing part 1 to which the DC pipe 3 is fixed and a second fixing part 2 to which it is fixed to the furniture (table 7).

[0062] Therefore, in the DC conduit system 100 of this embodiment, the DC conduit 3 can be fixed to the furniture via the conduit fixing device F1. Power can be supplied to the electrical device 94 from the DC conduit 3 by connecting the connector 95 of the electrical device 94 (or the connector of the cable connected to the electrical device 94) to the adapter 5A. Therefore, the wiring around the furniture is simpler compared to supplying power to the electrical device 94 from a power outlet or from a power tap that distributes power from the power outlet to the electrical device 94. In other words, the likelihood of the electrical device 94's wires becoming tangled and messy around furniture is reduced, and the wiring around the furniture is simplified.

[0063] Here, the term "furniture" to which the DC conduit system 100 is fixed refers collectively to household furniture and furniture used in residential or non-residential settings. Examples of furniture include tables, pedestals, and workbenches used as platforms for placing objects. Other examples of furniture include shelves, boxes, dressing tables, beds, whiteboards, screens, dividers, and benches. The following description will use the case where the DC conduit system 100 is fixed to a table 7 used as furniture as an example. Figure 9 As shown, the table 7 has a rectangular top plate 71, two legs 72, and two support bases 73 in the plan view. In the following description, the direction along the length of the DC conduit 3 is defined as the left-right direction. Furthermore, the direction along which the power receiving device 5 is attached to and detached from the DC conduit 3 is defined as the front-back direction, and the direction orthogonal to both the left-right and front-back directions is defined as the up-down direction. The side of the DC conduit 3 to which the adapter 5A is attached is defined as the front side, and when viewed from the front, the upper right end of the DC conduit 3 is defined as the first end 31A, and the upper left end is defined as the second end 31B. Note that these directions are not intended to limit the direction of use of the DC conduit system 100. Furthermore, Figure 1 The arrows indicating forward, backward, left, right, up, and down are for descriptive purposes only and are not substantive.

[0064] Furthermore, the DC piping system 100 of this embodiment includes a spacer 6 (see...) Figure 9 The separator fixing structure S1 (see) Figure 11 and 12 The term "separator" is also referred to as a partition or screen. Separation system 200 includes DC piping system 100 and separators 6. In this embodiment, three separators 6 are included in one separation system 200.

[0065] The partition 6 is fixed above the top plate 71. As a result, the space above the top plate 71 is divided into two spaces, with the partition 6 positioned between them. When some people (hereinafter referred to as "the first person") sit on one side of the table 7, and others (hereinafter referred to as "the second person") sit on the opposite side of the table, the partition 6 is positioned between the first person and the second person. This prevents the second person from being exposed to droplets spread by the first person's speech, sneezing, coughing, etc. Similarly, it prevents the first person from being exposed to droplets spread by the second person's speech, sneezing, coughing, etc.

[0066] (detail)

[0067] (1) DC piping system

[0068] The DC piping system 100 and its construction for use with the DC piping system will be described in more detail below.

[0069] like Figures 1 to 4 As shown in Figures 6 and 6, the DC piping system 100 includes two ( Figure 1 and 4 Only one DC pipe is shown in the image (3) and two (in the image). Figure 1 and Figure 4 Only one power supply component 4 (the so-called feed) is shown in the image, and two (only one is shown in the image) are shown in the image. Figure 6 The diagram shows an end cap CP1. The pipe fixing device F1 has two first fixing parts 1 and two second fixing parts 2. The two first fixing parts 1 correspond one-to-one with two DC pipes 3. Each first fixing part 1 fixes the corresponding DC pipe 3. One of the two second fixing parts 2 fixes one end of the two first fixing parts 1 along its length to the table 7, and the other of the two second fixing parts 2 fixes the other end of the two first fixing parts 1 along its length to the table 7.

[0070] In addition, the configuration used with the DC piping system 100 includes one or more adapters 5A (see...). Figure 6 and 13 ), three dividers 6 and table 7.

[0071] (2) Table

[0072] like Figure 9 As shown, the table 7 has a rectangular top plate 71 in plan view, two legs 72, and two support bases 73. One of the two legs 72 protrudes downward from near the right end of the top plate 71, and the other leg protrudes downward from near the left end of the bottom plate 71. The two support bases 73 correspond one-to-one with the two legs 72. Each support base 73 is connected to the lower end of the corresponding leg 72 and supports the leg 72.

[0073] (3) First fixing part

[0074] like Figure 10A As shown, the two first fixing parts 1 are arranged side by side in the front-rear direction and engage with each other. Figure 6 As shown, each of the two first fixing parts 1 includes a pipe receiving part 11 and two connecting protrusions 12. The pipe receiving part 11 and the two connecting protrusions 12 are formed as one piece.

[0075] The pipe receiving portion 11 is cuboid in shape. The pipe receiving portion 11 has a length in the left-right direction. One of the two connecting protrusions 12 protrudes from the right end of the pipe receiving portion 11, and the other protrudes from the left end of the pipe receiving portion 11. The pipe receiving portion 11 houses the DC pipe 3, specifically the pipe body (so-called pipe guide) 31 of the DC pipe 3. The pipe receiving portion 11 also houses the power supply component 4. Each of the two connecting protrusions 12 is configured to connect the first fixing portion 1 to the second fixing portion 2. Here, in the two DC pipes 3 respectively held by the two first fixing portions 1, the power supply component 4 is attached to the corresponding end of the first fixing portion 1 in the length direction. In this embodiment, as... Figure 10A As shown, in one DC conduit 3, a first power supply component 4A for the right end is connected to a first end 31A, which is the right end of the DC conduit 3, and in another DC conduit 3, a second power supply component 4B for the left end is connected to a second end 31B, which is the left end of the DC conduit 3. That is, the power supply component 4 includes a first power supply component 4A connected to the first end 31A and a second power supply component 4B connected to the second end 31B in the first end 31A and the second end 31B along the length direction of the DC conduit 3.

[0076] Each first fixing part 1 has a receiving groove 130 and two wire channel grooves 140. The receiving groove 130 accommodates the DC conduit 3 and the power supply component 4. The wires W1 and W2, which are electrically connected to the DC conduit 3, are shown in the figure. Figure 10A and 10B (Pass through the wire channel groove 140)

[0077] A receiving groove 130 is provided in the pipe receiving portion 11. The receiving groove 130 is formed along the length direction (left-right direction) of the pipe receiving portion 11. In each of the two first fixing portions 1, the receiving groove 130 opens on the outward-facing surface.

[0078] Two wire channel grooves 140 correspond one-to-one with two connecting protrusions 12. Each wire channel groove 140 is provided on the corresponding connecting protrusion 12 and pipe receiving portion 11. That is, the wire channel grooves 140 are respectively provided at the right end and the left end of the first fixing portion 1. Each wire channel groove 140 is formed along the length direction (left-right direction) of the pipe receiving portion 11. Each of the two first fixing portions 1 has a wire channel groove 140 that is open on its inward-facing surface.

[0079] When the two first fixing parts 1 are joined together, the wire channel grooves 140 at the right ends of the two first fixing parts 1 are joined together to form a space (see Figure 10AThe wire channel grooves 140 at the left ends of each of the two first fixing parts 1 are joined together to form another space. Each wire channel groove 140 is connected to the receiving groove 130. Wires W1 and W2 passing through the wire channel grooves 140 are electrically connected to the first terminal 43A and the second terminal 43B of the power supply member 4 received in the receiving groove 130 (see...). Figure 8 , 10A (and 10B). The positive side wire W1 is electrically connected to the first conductive bar 32A of the DC pipe 3 via the first terminal 43A, and the negative side wire W2 is electrically connected to the second conductive bar 32B of the DC pipe 3 via the second terminal 43B.

[0080] Furthermore, each of the two first fixing parts 1 has a portion of the separator fixing structure S1, such as Figure 6 As shown. That is to say, each of the two first fixed parts 1 has four ( Figure 6 (Only two are shown in the image.) Four recesses 150 are provided in the pipe receiving portion 11. In the two first fixing portions 1, the recesses 150 are provided on the inward-facing surface of the pipe receiving portion 11. The recesses 150 are provided from the upper end to the lower end of the pipe receiving portion 11.

[0081] When the two first fixing parts 1 are joined together, the four recesses 150 of each of the two first fixing parts 1 are joined together to form four gaps between the two first fixing parts 1. Each of these four gaps corresponds to a spacer fixing structure S1. More specifically, each spacer fixing structure S1 is a through hole vertically passing through the structure obtained by joining the two first fixing parts 1 together.

[0082] Four partition fixing structures S1 are arranged side by side in the left-right direction. Each of the four partition fixing structures S1 corresponds one-to-one with one of the four mounting protrusions belonging to the three partitions 6 (6A, 6B, 6C). The corresponding mounting protrusions are inserted into each partition fixing structure S1. Thus, each partition 6 is fixed to the two first fixing parts 1, namely the DC pipe 3.

[0083] (4) Second fixing part

[0084] like Figure 6 and Figure 9 As shown, each of the two second fixing parts 2 includes a horizontal portion 21, a support portion 22, and a clamping mechanism 23. The horizontal portion 21 and the support portion 22 are formed as one piece. The two second fixing parts 2 are structures (fixing members) for fixing the pipe body 31 to the furniture (table 7). More specifically, the two second fixing parts 2 are used in conjunction with the two first fixing parts 1 to fix the pipe body 31 to the furniture (table 7).

[0085] The horizontal portion 21 is rectangular in shape. The axial direction of the horizontal portion 21 is along the left-right direction.

[0086] Each of the two second fixing parts 2 corresponds one-to-one with the two connecting protrusions 12 provided at both ends of each of the two first fixing parts 1 in the left-right direction. The corresponding connecting protrusions 12 provided on each of the two first fixing parts 1 are inserted into the horizontal portion 21 of the second fixing part 2. Furthermore, the two first fixing parts 1 are threadedly connected to the two second fixing parts 2 respectively. As a result, the two first fixing parts 1 are connected to the two second fixing parts 2. That is, the two first fixing parts 1 are connected to the two second fixing parts 2 to bridge between the two second fixing parts 2. Moreover, each of the two first fixing parts 1 can be separated from the two second fixing parts 2. That is, by removing the screws connecting the two first fixing parts 1 and the two second fixing parts 2 and pulling out the connecting protrusions 12 from the horizontal portion 21, the two first fixing parts 1 can be separated from the two second fixing parts 2.

[0087] The support portion 22 is cylindrical in shape. The axial direction of the support portion 22 extends vertically. The horizontal portion 21 protrudes from the upper end of the support portion 22 in the left-right direction. The internal space of the horizontal portion 21 connects with the internal space of the support portion 22 to form an internal space SP1 (see...). Figure 10A A total of four wires, W1 and W2, connected in pairs to the two power supply components 4, pass through the internal space SP1. That is, the second fixing part 2 (fixing component) has an internal space SP1, through which wires W1 and W2, electrically connected to the first conductive strip 32A and the second conductive strip 32B (see...) Figure 1 (Pass through the interior space SP1.)

[0088] The support portion 22 has a wire channel hole 220. The wire channel hole 220 is provided on the side surface of the support portion 22. Wires W1 and W2 are led out from the internal space SP1 to the outside through the wire channel hole 220.

[0089] The clamping mechanism 23 secures the table 7 (furniture) to the table 7 (furniture) by clamping a portion of the table (furniture), such as the top panel 71. More specifically, one of the two second fixing parts 2 clamps one end of the top panel 71 along its length, and the other of the two second fixing parts 2 clamps the other end of the top panel 71 along its length. Thus, the DC piping system 100 is secured to the table 7 (furniture).

[0090] The clamping mechanism 23 has a movable part 231, a base 232 and an operating part 233.

[0091] The base 232 and the support 22 are formed as one piece. The base 232 protrudes from the lower end of the support 22 in the left-right direction.

[0092] The movable part 231 is disposed on the base 232. A portion of the movable part 231 is arranged inside the wire channel hole 220 of the support 22.

[0093] The operating part 233 receives an operation for moving the movable part 231 in the vertical direction. The operating part 233 is a lever, and when the operator rotates the operating part 233, the movable part 231 moves in the vertical direction.

[0094] The process of securing the DC piping system 100 to the table 7 using the clamping mechanism 23 will be described below. Figure 9 As shown, a portion (left or right end) of the top plate 71 of the table 7 is inserted into the electrical conduit hole 220. Consequently, a portion (left or right end) of the top plate 71 is positioned between the support 22 and the movable portion 231. The operator rotates the operating part 233 to move the movable portion 231 upwards. As a result, a portion (left or right end) of the top plate 71 is clamped between the support 22 and the movable portion 231. The DC piping system 100 is secured to the table 7 by clamping the left and right ends of the top plate 71 using the clamping mechanisms 23 of the two second fixing parts 2.

[0095] Furthermore, due to the presence of the support 22, a gap G1 is ensured between the two first fixing parts 1 of the DC piping system 100 and the top plate 71 of the table 7 (see...). Figure 9 In other words, the gap G1 ensures that it is located between the two pipe bodies 31 and the top plate 71 of the two first fixing parts 1. In other words, the second fixing part 2 (fixing member) includes a support part 22 that supports the two pipe bodies 31 with the gap G1 between the two pipe bodies 31 and the table 7 (furniture).

[0096] In this disclosure, the gap between the pipe body 31 and the table 7 (furniture) includes the following situation: as in this embodiment, there is a predetermined member (part of the first fixing part 1) between the pipe body 31 and the table 7, and there is a gap G1 extending from the lower surface of the predetermined member to the upper surface of the table 7. Furthermore, in this disclosure, the gap between the pipe body 31 and the table 7 (furniture) includes the case where there is a gap extending from the lower surface of the pipe body 31 to the upper surface of the table 7.

[0097] Objects such as documents can be passed across the divider 6 by passing through the gap G1. Furthermore, an opening can be provided in the portion of the top plate 71 of the table 7 located below the first fixing part 1. This opening is the space through which the AC power supply wire will pass and be pulled out from below the top plate 71. The user can insert their hand into the gap G1 and pull out the wire through the opening.

[0098] (5) DC pipe

[0099] like Figures 1 to 4 , Figure 6 and Figure 13 As shown, each of the two DC conduits 3 includes a conduit body 31 and two conductive strips 32 (first conductive strip 32A and second conductive strip 32B). The conduit body 31 includes a first metal guide rail 311 and two second synthetic resin guide rails 312.

[0100] Two DC conduits 3 correspond one-to-one with two first fixing parts 1. Each DC conduit 3 is housed in a receiving groove 130 of the corresponding first fixing part 1. For this purpose, the two DC conduits 3 are arranged on both sides in the front-rear direction, with the separator 6 located between them. That is, the DC conduit system 100 includes a plurality of (two) DC conduits 3, and the plurality of DC conduits 3 includes two DC conduits 3 arranged on both sides, with the separator 6 sandwiched between them. Therefore, in this embodiment, power can be supplied to the electrical devices 94 arranged on both sides of the separator 6.

[0101] Furthermore, with multiple DC pipes 3 fixed to the first fixing part 1 and the second fixing part 2 fixed to the furniture (table 7), the two DC pipes 3 are located on opposite sides of each other in a predetermined direction (front-back direction) along the horizontal plane. In other words, the two DC pipes 3 are arranged side by side in the front-back direction.

[0102] The first guide rail 311 is rectangular in shape. The first guide rail 311 extends along its axial direction (length direction) in the left-right direction. The first guide rail 311 includes a recess 3110. The recess 3110 is formed along the length direction (left-right direction) of the pipe body 31. More specifically, the recess 3110 is formed at both ends of the pipe body 31 along its length. Two conductive strips 32 are accommodated in the recess 3110.

[0103] The recess 3110 opens in a plane along the surface of the separator 6. More specifically, in each of the two DC channels 3, the recess 3110 opens in a surface opposite to the surface of the two DC channels 3 facing each other (the outward-facing surface). Note that in each of the two DC channels 3, the surface at the opening of the recess 3110 is referred to as the front surface. In each of the two DC channels 3, the end that is the right end when viewed from the front is referred to as the first end 31A, and the end that is the left end is referred to as the second end 31B.

[0104] like Figure 1 , 2A As shown in Figures 2B and 13, the first guide rail 311 also includes two mounting parts 3111 and two attachment slots 3112.

[0105] Each of the two mounting portions 3111 is a recess. The two mounting portions 3111 are disposed within the inner surface of the recess 3110. The two mounting portions 3111 are formed along the length direction (left-right direction) of the pipe body 31. More specifically, the two mounting portions 3111 are formed integrally on the pipe body 31 in the length direction. The two mounting portions 3111 are mounted to the adapter 5A. Therefore, the adapter 5A is attached to the DC pipe 3. That is, the pipe body 31 includes adapter attachment portions (two mounting portions 3111) for attaching the adapter 5A. The process for attaching the adapter 5A to the DC pipe 3 will be described later.

[0106] Two attachment grooves 3112 are provided in the inner surface of the recess 3110. Of the two mounting portions 3111 and the two attachment grooves 3112, the two mounting portions 3111 are positioned closer to the opening of the recess 3110. The two attachment grooves 3112 are formed along the length direction (left-right direction) of the pipe body 31. More specifically, the two attachment grooves 3112 are formed on the entire pipe body 31 in the length direction.

[0107] Two attachment slots 3112 correspond one-to-one with two second guide rails 312. The corresponding second guide rails 312 are fitted into each attachment slot 3112. Therefore, the two second guide rails 312 are attached to the first guide rail 311. The first guide rail 311 has two protrusions 3113 (see...). Figure 13 ), used to prevent the two second guide rails 312 from falling off.

[0108] In addition, the first guide rail 311 also has a limiting part 3114 (see Figure 13 The limiting part 3114 is a protrusion. (See limiting part 3114). Figure 13 It is positioned below the first guide rail 311. The limiting part 3114 is inserted into the limiting part 55 (recess) of the adapter 5A.

[0109] Each of the two second guide rails 312 has a length in the left-right direction. The second guide rail 312 is made of a synthetic resin such as PTC (polyvinyl chloride). The shape of the second guide rail 312 in cross-section perpendicular to the left-right direction is U-shaped. The second guide rail 312 holds the conductive strip 32 (first conductive strip 32A or second conductive strip 32B) inside.

[0110] Each of the two conductive strips 32 (first conductive strip 32A or second conductive strip 32B) has a length in the left-right direction. Each of the first conductive strip 32A and the second conductive strip 32B extends from the right end to the left end of the pipe body 31. The first conductive strip 32A and the second conductive strip 32B are electrically connected to corresponding wires W1 and W2 (see power supply component 4) via the power supply component 4. Figure 7 , 8(and 10A). In this embodiment, the first conductive strip 32A is electrically connected to the positive electrode wire W1, the second conductive strip 32B is electrically connected to the negative electrode wire W2, and the first conductive strip 32A and the second conductive strip 32B are supplied with DC power.

[0111] The pipe body 31 has mounting portions at a first end (e.g., right end) 31A and a second end (e.g., left end) 31B in the longitudinal direction for mating with the power supply component 4. Therefore, the pipe body 31 is provided with an anti-connection structure that restricts the end to which the power supply component 4 can be attached to to either the first end 31A or the second end 31B. In this embodiment, the anti-connection structure includes a protrusion 35 provided on the inner surface of the pipe body 31. The protrusion 35 is provided below the rear wall of the recess 3110 in the pipe body 31. The protrusion 35 is provided on the entire length (left-right direction) of the pipe body 31. That is, the DC pipe 3 has an anti-connection structure (protrusion 35) on the entire length (left-right direction) of the first conductive strip 32A and the second conductive strip 32B.

[0112] Therefore, as Figure 2A and 2B As shown, when the DC conduit 3 is viewed from the length direction, the shape of the assembly part (first end 31A and second end 31B) of the DC conduit 3 into which the power supply component 4 is assembled is asymmetrical with respect to the centerline L1 of the DC conduit 3 in a predetermined direction. The predetermined direction is a direction perpendicular to both the attachment direction (front-back direction) and the length direction (left-right direction) of the power receiving device 5 (adapter 5A, etc.) attached to the DC conduit 3 (vertical direction).

[0113] A protrusion 35 is provided on the pipe body 31 as an anti-connection structure, and the protrusion 35 is disposed on the entire length of the pipe body 31. Therefore, when attempting to connect the first power supply member 4A, which can be connected to the first end 31A, to the second end 31B, the power supply member body 42 of the first power supply member 4A interferes with the protrusion 35 at the second end 31B, thus preventing the first power supply member 4A from connecting to the second end 31B. Furthermore, when attempting to connect the second power supply member 4B, which can be connected to the second end 31B, to the first end 31A, the power supply member body 42 of the second power supply member 4B interferes with the protrusion 35 on the first end 31B, thus preventing the second power supply member 4B from connecting to the first end 31A. In other words, the anti-connection structure (protrusion 35) prevents the first power supply member 4A from connecting to the second end 31B and prevents the second power supply member 4B from connecting to the first end 31A. Therefore, the advantage of the power supply component 4 is that it can prevent connection to the ends of the first end 31A and the second end 31B that are opposite to the ends that allow the power supply component 4 to be connected, and the first contact 44A and the second contact 44B of the power supply component 4 are reliably connected to the first conductive bar 32A and the second conductive bar 32B, respectively.

[0114] Furthermore, since the pipe body 31 has a protrusion 35 as an anti-connection structure along its entire length, the first end 31A and the second end 31B of the pipe body 31 can be formed to have the same shape, even if the pipe body 31 is cut to an appropriate length according to the size of the furniture to which the DC pipe 3 is attached.

[0115] (6) Power supply components and end caps

[0116] like Figure 6 As shown, two power supply components 4 correspond one-to-one with two DC pipes 3. Two end caps CP1 correspond one-to-one with two DC pipes 3. The corresponding power supply component 4 is attached to one of the first end 31A and the second end 31B of each DC pipe 3, and the corresponding end cap CP1 is attached to the other.

[0117] As described above, the power supply component 4 is configured to be connected only to one of the first end 31A and the second end 31B of the DC conduit 3. That is, the power supply component 4 includes a first power supply component 4A connected to the first end 31A of the conduit body 31 and a second power supply component 4B connected to the second end 31B of the conduit body 31. Note that a DC conduit 3 may be connected only to one of the first power supply component 4A and the second power supply component 4B.

[0118] The power supply component 4 (first power supply component 4A and second power supply component 4B) is configured to electrically connect the two conductive strips 32 (first conductive strip 32A and second conductive strip 32B) of the DC conduit 3 to the corresponding wires W1 and W2 (see Figure 8 and 10A In other words, the first conductive strip 32A and the second conductive strip 32B are electrically connected to the corresponding wires W1 and W2 via the power supply component 4. Hereinafter, the second power supply component 4B will be used as an example for reference. Figure 8 The construction of power supply component 4 is described. Note that, except for protrusions 45A and 45B, the construction of the first power supply component 4A is the same as that of the second power supply component 4B, therefore the description of the first power supply component 4A is omitted.

[0119] The power supply component 4 (second power supply component 4B) includes an outer box 41, a power supply component body 42, and two terminals 43.

[0120] The outer box 41 has a cuboid shape. The outer box 41 houses the power supply component body 42. The power supply component body 42 has a first block 421 and a second block 422. By coupling the first block 421 and the second block 422 together, a box-shaped component (power supply component body 42) is formed.

[0121] The main body 42 of the power supply component accommodates two terminals 43. Furthermore, the main body 42 of the power supply component has two wire sockets 423 into which two wires W1 and W2 are inserted. The two wire sockets 423 are located in the first block 421.

[0122] The two terminals 43 include a first terminal 43A connected to the positive side wire W1 of the DC power supply and a second terminal 43B connected to the negative side wire W2 of the DC power supply. A first contact 44A is integrally formed with the first terminal 43A, and a second contact 44B is integrally formed 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...). Figure 10B A set of springs 431 and terminal portions 432 constitute a quick-connect terminal. That is, each of the two terminals 43 has a quick-connect terminal.

[0123] Spring 431 is formed by bending a metal plate, etc. Terminal portion 432 is made of metal plate and formed in a plate shape. Terminal portion 432 faces spring 431. Two terminals 43 (first terminal 43A and second terminal 43B) correspond one-to-one with two conductive bars 32 (first conductive bar 32A and second conductive bar 32B). 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, first terminal 43A includes a first contact 44A formed by terminal portion 432, and second terminal 43B includes a second contact 44B formed by terminal portion 432.

[0124] like Figure 10A and 10B As shown, each of the wires W1 and W2, which are inserted into the power supply component body 42 through the wire socket 423, is clamped between the spring 431 and the terminal portion 432. Therefore, each of the 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.

[0125] As described above, the power supply component 4 is configured to be connected only to one of the first end 31A and the second end 31B of the DC conduit 3.

[0126] The main body 42 of the power supply component 4 is provided with a protrusion 45, which interferes with the protrusion 35 of the DC conduit 3 to prevent the power supply component 4 from being connected to the end opposite to the end that can be connected to the first end 31A and the second end 31B of the DC conduit 3. In the following, in some cases, the protrusion 45 provided on the main body 42 of the first power supply component 4A will be referred to as protrusion 45A, and the protrusion 45 provided on the main body 42 of the second power supply component 4B will be referred to as protrusion 45B.

[0127] The power supply component body 42 of the second power supply component 4B, which can be connected to the second end 31B of the DC pipe 3, has a protrusion 45B at the position where it interferes with the protrusion 35 when attempting to insert the power supply component body 42 into the first end 31A. Figure 4 Since the protrusion 45B is located on the opposite side of the protrusion 35 in the vertical direction (on the upper side when connected to the second end 31B of the DC conduit 3), the protrusion 45B does not interfere with the protrusion 35 when the power supply component body 42 is inserted into the second end 31B. Therefore, the second power supply component 4B is configured to be connected only to the second end 31B of the DC conduit 3, and is prevented from being attached to the side of the DC conduit 3 opposite to the side that is allowed to be connected.

[0128] Furthermore, the power supply component body 42 of the first power supply component 4A, which can be connected to the first end 31A of the DC pipe 3, has a protrusion 45A at the position where it interferes with the protrusion 35 when the power supply component body is inserted into the second end 31B (see...). Figure 1 Since the protrusion 45A is located on the opposite side of the protrusion 35 in the vertical direction (on the upper side when connected to the first end 31A of the DC conduit 3), the protrusion 45A does not interfere with the protrusion 35 when the power supply component body 42 is inserted into the first end 31B. Therefore, the first power supply component 4A is configured to be connected only to the first end 31A of the DC conduit 3, and is prevented from being attached to the side of the DC conduit 3 opposite to the side that is allowed to be connected.

[0129] Furthermore, the power supply component body 42 is provided with markings M1 and M2 as polarity indicators, indicating the polarity of the wires W1 and W2 connected to the two terminals 43 (first terminal 43A and second terminal 43B). Markings M1 and M2 are respectively provided on the surface of the power supply component body 42 near the wire sockets 423 corresponding to the first terminal 43A and the second terminal 43B. Markings M1 and M2 are provided on the power supply component body 42 using appropriate methods—such as resin molding, engraving, printing, painting, or affixing stickers or nameplates with markings M1 and M2 printed on them. Since the polarity indicators (markings M1 and M2) are provided on the surface of the power supply component body 42, it is advantageous that polarity errors are less likely to occur when wires W1 and W2 are connected to the first terminal 43A and the second terminal 43B.

[0130] (7) Divider

[0131] The following will refer to Figure 9 The separator 6 is described below. In the following text, the three separators 6 can be distinguished and referred to as separators 6A, 6B, and 6C, respectively. The common features shared among the three separators 6 are indicated by the same reference numerals, and redundant descriptions are omitted where appropriate. Of the three separators 6, separator 6A is located on the far right, separator 6C is located on the far left, and separator 6B is located between separators 6A and 6C.

[0132] Each of the separators 6A to 6C has a translucent, plate-shaped separator body 61. The material of the separator 6 is, for example, acrylic resin. The lower part of the separator body 61 is provided with a mating protrusion that is inserted into the separator fixing structure S1 (through hole).

[0133] The mating protrusions of the three partition members 6 are inserted into the corresponding partition member fixing structures S1 (through holes). Thus, each partition member 6 is fixed to the DC piping system 100. That is, the partition member fixing structure S1 is a structure that mates with the partition member 6. Each partition member 6 can be removed from the DC piping system 100 by removing the mating protrusion from the partition member fixing structure S1. In other words, the partition member fixing structure S1 detachably fixes the partition member 6.

[0134] (8) Adapter

[0135] like Figure 9 and 10A As shown, a first fixing part 1 is provided on both sides in the front-rear direction, with a separator 6 between them, and each first fixing part 1 accommodates a DC pipe 3. The adapter 5A can be attached to these two DC pipes 3 respectively.

[0136] like Figures 11 to 13As shown, adapter 5A has a housing 51, a release operation portion 52, an attachment protrusion 53, two power receiving terminals 54, and a spring housed in the housing 51.

[0137] The housing 51 is rectangular in shape. The housing 51 has a first insertion port 511 and a second insertion port 512. The first insertion port 511 is the insertion port for a USB-A plug used as connector 95 (see...). Figure 14 The second insertion port 512 is an insertion port for use as a USB-C plug for connector 95. That is, the first insertion port 511 has a different standard than the second insertion port 512. The dimensions of the first insertion port 511 are different from those of the second insertion port 512.

[0138] When adapter 5A is attached to DC conduit 3, the first insertion port 511 and the second insertion port 512 are located on the surface facing away from DC conduit 3 (connector mounting surface 501). When adapter 5A is attached to DC conduit 3, the first insertion port 511 and the second insertion port 512 are arranged side by side in the vertical direction.

[0139] The release operation portion 52 is held by the housing 51. The release operation portion 52 can move in a predetermined direction due to an applied force. The restoring force of the spring housed in the housing 51 acts on the release operation portion 52. Therefore, when no force is applied to the release operation portion 52, the front end portion (claw portion 520) of the release operation portion protrudes from the housing 51 to the side opposite to the side of the connector mounting surface 501.

[0140] The attachment protrusion 53 includes a shaft portion 531 and two ribs 532. The shaft portion 531 protrudes from the housing 51 to a side opposite to the connector mounting surface 501. The two ribs 532 protrude from the side surface of the shaft portion 531. The two ribs 532 protrude in opposite directions.

[0141] Two power receiving terminals 54 protrude from the housing 51 to the side opposite to the connector mounting surface 501. The front end of each of the two power receiving terminals 54 is bent.

[0142] Adapter 5A has a limiting part 55. The limiting part 55 is a recess formed in the surface of adapter 5A (the surface facing DC pipe 3). When adapter 5A is attached to pipe body 31, the limiting part 3114 (protrusion) of pipe body 31 is inserted into the limiting part 55. If the orientation of adapter 5A is incorrect (i.e., if...), Figure 11If the direction shown is inverted, the limiting part 3114 will interfere with the adapter 5A, thus preventing the adapter 5A from being attached to the pipe body 31. In other words, when the adapter 5A is attached to the pipe body 31, the limiting parts 55 and 3114 restrict the orientation of the adapter 5A. As a result, of the two power receiving terminals 54, the positive-side power receiving terminal 54 is connected to the positive-side first conductive strip 32A, and the negative-side power receiving terminal 54 is connected to the negative-side second conductive strip 32B.

[0143] Adapter 5A also includes a voltage converter. The voltage converter converts the DC voltage received by the two power receiving terminals 54 into a DC voltage with the desired voltage value. The DC voltage, whose voltage value has been converted by the voltage converter, is output from the first insertion port 511 and the second insertion port 512. The DC voltage is applied to the electrical device 94 (see [link to adapter]) via a cable including a connector 95 connected to the first insertion port 511 or the second insertion port 512. Figure 14 ).

[0144] The process of connecting adapter 5A to DC pipe 3 will be described below.

[0145] exist Figure 12 and 13 In the orientation of the housing 51 shown, two ribs 532 are arranged side by side in the vertical direction.

[0146] First, such as Figure 11 As shown, the worker holds the adapter 5A so that the two ribs 532 are arranged side-by-side along the length (left-right direction) of the pipe body 31. In this state, the attachment protrusion 53 can be inserted into the recess 3110 of the pipe body 31 without the two ribs 532 interfering with the pipe body 31. The release operation part 52 moves toward the connector mounting surface 501 due to the contact pressure with the first fixing part 1.

[0147] like Figure 11 As shown, after inserting the attachment protrusion 53 into the recess 3110, the worker rotates the adapter 5A 90 degrees clockwise, as... Figure 12 and 13 As shown. Then, insert the two ribs 532 into the two assembly parts 3111, as shown. Figure 13 As shown. This restricts the movement of adapter 5A in the front-to-back direction. Furthermore, as... Figure 12 As shown, the claw 520 of the release operation unit 52 is inserted into the recess 3110 of the pipe body 31 to restrict the rotation of the housing 51, so that the adapter 5A is held in place while being attached to the DC pipe 3. In addition, the two power receiving terminals 54 respectively contact the corresponding conductive strips 32 (first conductive strip 32A and second conductive strip 32B), thereby electrically connecting to the corresponding conductive strips 32.

[0148] The adapter 5A is connected to the DC conduit 3 via the steps described above. The adapter 5A can be attached to the DC conduit 3 and electrically connected to the conductive strip 32 at any location in the area where the recess 3110 is provided (attachment area).

[0149] Note that in this embodiment, no structure is provided for limiting the movement of the adapter 5A attached to the DC conduit 3 in the left-right direction. Therefore, the adapter 5A can move in the left-right direction while attached to the DC conduit 3. However, in order to suppress wear on the two power receiving terminals 54 caused by the movement of the adapter 5A in the left-right direction, the DC conduit system 100 may also include a structure for limiting the movement of the adapter 5A attached to the DC conduit 3 in the left-right direction.

[0150] Next, the process of removing adapter 5A from DC conduit 3 will be described. When the worker applies a force toward connector mounting surface 501 to release operating part 52, release operating part 50 moves and claw 520 emerges from recess 3110. As a result, the restriction on rotation of housing 51 is released. When the worker rotates housing 51 counterclockwise 90 degrees, two ribs 532 emerge from two mounting parts 3111. The adapter 5A is thus removed from DC conduit 3 through the above process.

[0151] (9) Power supply system

[0152] Next, refer to Figure 14 This section will describe a construction example of a system (including DC piping system 100) that supplies power to electrical device 94.

[0153] A switching hub 92 and a splitter 93 are provided in the facility using electrical equipment 94. The switching hub 92 is electrically connected to an AC power source 91. The AC power source 91 supplies AC power to the switching hub 92. The AC power source 91 is, for example, a commercial power source or a distributed power source.

[0154] Switch hub 92 is a PoE (Power over Ethernet) compatible switch hub and includes a DC power supply section 921. The DC power supply section 921 converts the AC voltage input from AC power supply 91 into a DC voltage with a predetermined voltage value and outputs this DC voltage to splitter 93. Switch hub 92 is electrically connected to splitter 93 via a LAN (Local Area Network) cable. Furthermore, switch hub 92 can also be electrically connected to PoE compatible devices. PoE compatible devices include, for example, computer terminals, network cameras, IP (Internet Protocol) phones, wireless access points, etc. Switch hub 92 can exchange PoE signals containing data and power (DC power) with devices electrically connected to switch hub 92.

[0155] Splitter 93 is a PoE-compatible splitter and includes a DC power supply section 931. The DC power supply section 931 converts the DC voltage input from the switching hub 92 into a DC voltage with a predetermined value and outputs this DC voltage to the DC conduit 3. Splitter 93 splits the PoE signal received from the switching hub 92 into data and power (DC power). Splitter 93 supplies the power split from the PoE signal to non-PoE devices. For example, splitter 93 supplies the power separated from the PoE signal to one or more non-PoE electrical devices 94 via the DC conduit system 100.

[0156] In addition, splitter 93 sends a data signal to non-PoE devices, including data split from the PoE signal.

[0157] In this embodiment, the DC power supply section PE1 that converts the AC voltage input from the AC power supply 91 into DC voltage and outputs the DC voltage to the power supply component 4 is composed of the DC power supply section 921 of the switching hub 92 and the DC power supply section 931 of the splitter 93.

[0158] The DC power output terminal of the splitter 93 is electrically connected to the first end of each of the two wires W1 and W2. One of the two DC conduits 3 corresponds to one pair of the two pairs of wires W1 and W2, while the other DC conduit corresponds to the remaining two wires W1 and W2. The following description focuses on one DC conduit 3, the two wires W1 and W2 corresponding to that DC conduit 3, and a power supply component 4.

[0159] The two wires W1 and W2 are the positive terminal wire W1 and the negative terminal wire W2. The two wires W1 and W2 are connected to two wire sockets 423 (see...) in the power supply component 4. Figure 8 A one-to-one correspondence exists. Furthermore, the two wires W1 and W2 correspond one-to-one with the first conductive bar 32A and the second conductive bar 32B of the DC conduit 3. The second end of the positive-side wire W1 is inserted into the corresponding wire socket 423, connected to the first terminal 43A, and electrically connected to the first conductive bar 32A via the first terminal 43B. The second end of the negative-side wire W2 is inserted into the corresponding wire socket 423, connected to the second terminal 43B, and electrically connected to the second conductive bar 32B via the second terminal 43B. One or more adapters 5A can be connected to the DC conduit 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 adapters 5A.

[0160] As described above, each electrical device 94 can receive power supplied from the DC power supply section 931 via wires W1 and W2 (i.e., DC power output from the DC power supply section 931) via the conductive strip 32 and adapter 5A. The user can use the electrical device 94 on or around the table 7 (see...). Figure 9 ).

[0161] The DC voltage (voltage between the two conductive strips 32) received by adapter 5A from the two conductive strips 32 is preferably 60V or lower. In this case, there is an advantage that no electrician's certificate is required when installing adapter 5A. Therefore, power supply can be easily secured compared to relocating or installing a new AC 100V socket.

[0162] The DC voltage received by adapter 5A from the two conductive strips 32 (i.e., the DC voltage output by the DC power supply section 931) is more preferably 24V or lower. Furthermore, the DC voltage received by adapter 5A from the two conductive strips 32 is preferably 48V or lower.

[0163] For example, the DC voltage of the PoE signal output from the DC power supply section 921 of the switching hub 92 is 48V. The DC power supply section 931 of the splitter 93 has the function of stepping down the DC voltage of the PoE signal received from the switching hub 92, and the DC voltage output from the DC power supply section 931 of the splitter 93 is, for example, 24V. The adapter 5A receives the DC voltage output from the splitter 93 and outputs a DC voltage of 24V or lower to the electrical device 94.

[0164] By setting the voltage between the two conductive strips 32 of the DC conduit 3 to 60V or lower (e.g., 24V), the likelihood of electric shock when a user touches the conductive strips 32 can be reduced. Therefore, a cover for the DC conduit 3 is not required, and the task of attaching and removing the cover during the process of attaching the adapter 5A to the DC conduit 3 is time-efficient.

[0165] Although an example of the construction of a system for supplying power to electrical appliance 94 has been described above, wires W1 and W2 can also be more simply connected to a commercial power outlet via AC adapter 96 (see...). Figure 7 ).

[0166] (10) Advantages

[0167] Because the DC conduit 3 of the first embodiment has an anti-connection structure, the power supply components 4 (first power supply component 4A and second power supply component 4B) can be connected only to predetermined ends of the first end 31A and the second end 31B of the DC conduit 3. Therefore, when the first power supply component 4A and the second power supply component 4B are connected to the DC conduit 3, the positive side first contact 44A is connected to the positive side first conductive strip 32A, and the negative side second contact 44B is connected to the negative side second conductive strip 32B. Therefore, when the first power supply component 4A and the second power supply component 4B are connected to the DC conduit 3, the possibility of the positive side first contact 44A being mistakenly connected to the negative side second conductive strip 32B and the negative side second contact 44B being mistakenly connected to the positive side first conductive strip 32A can be reduced.

[0168] The main body 42 of the power supply component 4 (first power supply component 4A and second power supply component 4B) is provided with a polarity indicator (markers M1 and M2) indicating the polarity of the wires connected to the first terminal 43A and the second terminal 43B, respectively. Therefore, when connecting wires to the first terminal 43A and the second terminal 43B, the possibility of connecting wires with incorrect polarity can be reduced. Thus, the possibility of DC voltage with incorrect polarity being applied to the first conductive strip 32A and the second conductive strip 32B of the DC conduit 3 can be reduced.

[0169] (Variations of the first embodiment)

[0170] The following are variations of the first embodiment. These variations can be combined with each other as appropriate.

[0171] (First variant)

[0172] The furniture using the DC piping system 100 of the first embodiment is not limited to the table 7 on either side of the seats, but can be as follows: Figure 15 Table 7C is shown.

[0173] Table 7C is a table designed so that the user sits only in front of it, such as a counter. Table 7C includes a table body 70, a pipe fixing device F2 for fixing the DC pipe 3, and a back panel 74. The pipe fixing device F2 has a first fixing part 1C and two second fixing parts 2C. Table body 70 includes a top plate 701, a protruding base 702, and a support body 703. The DC pipe 3 is attached to table 7C. Power supply component 4 and adapter 5A (see...) Figure 12 ) Attached to DC pipe 3.

[0174] (Second variant)

[0175] Reference Figure 16 and Figure 17 Describes the second variant of the DC piping system 100.

[0176] The second variant of the DC piping system 100 differs from the above embodiment in that it includes a notification section 80 (see...). Figure 16 The notification section 80 notifies the user of the state of DC voltage application to the first contact 44A and the second contact 44B of the power supply component 4. This notification includes indicating whether a DC voltage of predetermined polarity is being applied to the first contact 44A and the second contact 44B. Furthermore, the notification can be performed by outputting light or sound, or both, and can also be performed by sending information to a portable communication terminal (e.g., a smartphone) owned by a user (e.g., a worker connecting the power supply component 4). Note that since the components other than the notification section 80 are the same as those in the above embodiment, the same components are indicated by the same reference numerals, and their descriptions are omitted.

[0177] For example, the notification section 80 is located in the power supply component 4. Figure 16 As shown, the notification section 80 includes a resistor 82 and a light source 81, which are connected between a first terminal 43A and a second terminal 43B. The light source 81 is, for example, a light-emitting diode (LED) and is connected between a first contact 44A and a second contact 44B, with the anode on the first contact 44A side and the cathode on the second contact 44B side. The notification section 80 is housed within the power supply component body 42, and the light source 81 is visible from the outside of the power supply component body 42 through a hole in the surface of the power supply component body 42 (see [link to documentation]). Figure 17 Note that the light source 81 is not limited to light-emitting diodes, but can also be a solid-state light source such as organic EL (organic electroluminescent), incandescent lamp, neon lamp, etc.

[0178] When the positive-side wire W1 is connected to the first terminal 43A and the negative-side wire W2 is connected to the second terminal 43B, that is, when wires W1 and W2 of predetermined polarity are connected to the first terminal 43A and the second terminal 43B, the light source 81 is illuminated. On the other hand, when the negative-side wire W2 is connected to the first terminal 43A and the positive-side wire W1 is connected to the second terminal 43B, the light source 81 is turned off. As a result, the worker performing the wire connection task can easily check whether the wires W1 and W2 from the DC power supply section PE1 are connected to the first terminal 43A and the second terminal 43B of predetermined polarity by checking whether the light source 81 is illuminated. Therefore, the possibility of applying DC voltage to the first conductive strip 32A and the second conductive strip 32B with incorrect polarity can be further reduced.

[0179] Note that, as Figure 18As shown, the light-emitting diode (LED) serving as the light source 81 can also be connected between the first contact 44A and the second contact 44B, with the cathode on the first contact 44A side and the anode on the second contact 44B side. In this case, when a DC voltage is applied to the first contact 44A and the second contact 44B such that the voltage of the second contact 44B is higher than the voltage of the first contact 44B, the light source 81 is lit. That is, the light source 81 is lit when the negative side wire W2 is incorrectly connected to the first terminal 43A and the positive side wire W1 is incorrectly connected to the second terminal 43B, so the worker can easily confirm that the incorrect connection of wires W1 and W2 has occurred due to the fact that the light source 81 is lit. Furthermore, if wires W1 and W2 are connected to the first terminal 43A and the second terminal 43B with a predetermined polarity (if no incorrect connection occurs), the light source 81 is turned off, thus also having the advantage of suppressing power consumption.

[0180] Note that, as Figure 19 As shown, the power supply component 4 may also be provided with a first notification part 80A and a second notification part 80B as a notification part 80.

[0181] The first notification section 80A includes a resistor 82A and a light source 81A, which are connected between a first terminal 43A and a second terminal 43B. The light source 81A is, for example, a light-emitting diode (LED) and is connected between a first contact 44A and a second contact 44B, with the anode on the first contact 44A side and the cathode on the second contact 44B side. The first notification section 80A has a light source 81A that illuminates when the positive-side wire W1 is connected to the first terminal 43A and the negative-side wire W2 is connected to the second terminal 43B. The light source 81A of the first notification section 80A is arranged on the surface of the power supply component body 42, near the wire socket 423 corresponding to the first terminal 43A.

[0182] The second notification section 80B includes a resistor 82B and a light source 81B connected between a first terminal 43A and a second terminal 43B. The light source 81B is, for example, a light-emitting diode (LED) and is connected between a first contact 44A and a second contact 44B, with the anode on the second contact 44B side and the cathode on the first contact 44A side. The second notification section 80B has a light source 81B that illuminates when the second terminal 43B is connected to the positive side wire W1 and the first terminal 43A is connected to the negative side wire W2. The light source 81B of the second notification section 80B is arranged on the surface of the power supply component body 42, near the wire socket 423 corresponding to the second terminal 43B.

[0183] Therefore, if the power supply component 4 includes a first notification portion 80A and a second notification portion 80B, it is possible to check whether an incorrect wiring connection has occurred based on which of the light sources 81A of the first notification portion 80A and 81B of the second notification portion 80B is lit.

[0184] Note that, as Figure 20 As shown, it is not necessary for the notification section 80 to be located on the power supply component 4, and the notification section 80 can also be located on the DC pipe 3. Figure 20 The notification section 80 shown is configured to illuminate when a wire with a polarity different from the predetermined polarity is incorrectly connected to the first terminal 43A and the second terminal 43B, but it can also be configured to illuminate when a wire of the predetermined polarity is connected. Furthermore, the DC conduit 3 may include a first notification section 80A that illuminates when a wire of the predetermined polarity is connected to the first terminal 43A and the second terminal 43B, and a second notification section 80B that illuminates when an incorrect wire connection occurs.

[0185] In addition, the adapter 5A connected to the DC pipe 3 may include a notification section 80, which can check whether a DC voltage of a predetermined polarity is being supplied to the adapter 5A.

[0186] In addition, the power receiving device that can be connected to DC conduit 3 may include inspection device 9 (see Figure 21 The inspection device 9 includes a notification section 80. If the inspection device 9 is connected to the DC pipe 3 during the construction of the DC pipe 3, an incorrect wiring connection can be checked by checking whether the light source 81 included in the notification section 80 is lit.

[0187] Furthermore, the notification section 80 is not limited to notifying the application status of the DC voltage to the first contact 44A and the second contact 44B via light, but can also notify via sound. Figure 22 The notification section 80 shown includes a diode 83 and a buzzer circuit 84, which are connected between the first terminal 43A and the second terminal 43B. In the notification section 80, when the positive-side wire W1 is connected to the second terminal 43B and the negative-side wire W2 is connected to the first terminal 43A, current flows through the buzzer circuit 84 and an alarm sound is output. Therefore, the worker performing the wiring connection task can check whether an incorrect wiring connection has occurred based on whether the notification section 80 emits an alarm sound. Note that in Figure 22 In the circuit shown, a light-emitting diode (LED) can be used instead of diode 83, and notification can be performed by the light emitted by the LED and the sound emitted by the buzzer circuit 84.

[0188] (Other variations)

[0189] In the above embodiment, the DC pipe 3 is provided with a protrusion 35 as an anti-connection structure, but the shape and position of the protrusion 35 can be appropriately changed. In addition, it is not necessary to provide a protrusion 35 as an anti-connection structure along the entire length of the DC pipe 3; the anti-connection structure can also be provided only at the first end 31A and the second end 31B of the DC pipe 3.

[0190] Some components of the DC piping system 100 can be provided independently of other components. For example, the DC pipe 3, the pipe fixing device F1, the first fixing part 1 or the second fixing part 2 (fixing member) can be provided independently of other components.

[0191] The number of individual components shown in the first embodiment is illustrative and is not limited to the number shown in the first embodiment. For example, the DC piping system 100 is not limited to having two DC pipes 3, but may also have one, three or more DC pipes 3. Furthermore, the DC piping system 100 is not limited to having two first fixing parts 1, but may also have one, three or more first fixing parts 1. Furthermore, the DC piping system 100 is not limited to having two second fixing parts 2, but may also have one, three or more second fixing parts 2. Furthermore, the partition system 200 is not limited to having three partitions 6, but may also have one, two, four or more partitions 6.

[0192] The plurality of DC conduits 3 may also include two or more DC conduits 3 arranged side by side in the vertical direction. Furthermore, the voltage of the conductive strip 32 may be different for each of the two or more DC conduits 3. Additionally, the standard of the adapter 5A that can be attached to each of the two or more DC conduits 3 may be different. For example, since the two or more DC conduits 3 have recesses 3110 with different widths or depths, the shape of the adapter 5A that can be attached to each of the two or more DC conduits may be limited. Furthermore, in the DC conduit 3, the first conductive strip 32A on the positive side may be arranged on the lower side, and the second conductive strip 32B on the negative side may be arranged on the upper side.

[0193] One first fixing part 1 can also fix two or more DC pipes 3. Alternatively, two or more first fixing parts 1 can fix one DC pipe 3.

[0194] Two or more DC pipes 3 can be connected along their length (left-right direction).

[0195] As a second fixing part 2, it is also possible to prepare a second fixing part 2 with multiple standards, wherein the length of the horizontal part 21 is different. By replacing the second fixing part 2 with another second fixing part 2 of different standards, the distance between the corresponding support parts 22 of the two second fixing parts 2 on both sides of the first fixing part 1 can be adjusted according to the length of the furniture (table 7).

[0196] The construction of the second fixing part 2 is not limited to the construction of fixing it to the furniture by the clamping mechanism 23. The second fixing part 2 can also be constructed to be fixed to the furniture, for example, by a threaded connection. In addition, by providing the first fixing part with a component to be fixed to the furniture by thread, the first fixing part 1 can also be used as the second fixing part 2.

[0197] In the above embodiment, the voltage supplied to the electrical device 94 can be easily changed by replacing adapter 5A with another adapter that has a different output voltage for connector 95.

[0198] Furthermore, connector 95 is not limited to a plug, but can also be a socket (insertion port). DC conduit 3 can also connect both a first adapter and a second adapter; the first adapter can connect to the plug used as connector 95, and the second adapter can connect to the socket used as connector 95. This allows for the handling of electrical devices 94 or cables with plugs or sockets. The first and second adapters can also share the same construction as connector 95, except for the connection portion.

[0199] (Second Embodiment)

[0200] Reference Figure 23 A second embodiment of the DC piping system 100 is described. In the second embodiment of the DC piping system 100, the same components as in the first embodiment are indicated by the same reference numerals, and their description is omitted.

[0201] The DC conduit system 100 includes a DC conduit 3 and a power supply component 4C. Since the construction of the DC conduit 3 is the same as that of the first embodiment, its description is omitted. The power supply component 4C differs from the power supply component 4 of the first embodiment in that it includes a first connector 46 instead of first terminals 43A and second terminals 43B. The first connector 46 is, for example, a socket-type connector. A plug-type second connector 97, disposed on the wire W3 of a DC power supply (e.g., AC adapter 96) that outputs DC voltage, can be connected to the first connector 46. With the second connector 97 connected to the first connector 46, DC voltage is applied from the DC power supply (AC adapter 96) to the first contact 44A and the second contact 44B. Note that the power supply component 4C includes a right-end first power supply component connected to the first end 31A, which is the right end of the DC conduit 3, and a left-end second power supply component connected to the second end 31B, which is the left end of the DC conduit 3. Figure 23 The power supply component 4C shown is the second power supply component on the left end of the second end 31B of the DC pipe 3.

[0202] Since the DC conduit 3 of the second embodiment has a connection prevention structure similar to that of the first embodiment, the power supply component 4C can only be connected to a predetermined end of the first end 31A and the second end 31B of the DC conduit 3. Therefore, when the power supply component 4C is connected to the DC conduit 3, the positive side first contact 44A is connected to the positive side first conductive bar 32A, and the negative side second contact 44B is connected to the negative side second conductive bar 32B. As a result, when the power supply component 4C is connected to the DC conduit 3, the possibility that the positive side first contact 44A will be mistakenly connected to the negative side second conductive bar 32B and the negative side second contact 44B will be mistakenly connected to the positive side first conductive bar 32A can be reduced.

[0203] In the second embodiment, by connecting the second connector 97 disposed on the wire W3 of the AC adapter 96, which serves as the DC power supply section, to the first connector 46 of the power supply component 4C, erroneous connections when connecting the power supply component 4C and the DC power supply section are suppressed. Therefore, the possibility of a DC voltage with incorrect polarity being applied to the first conductive strip 32A and the second conductive strip 32B of the DC conduit 3 can be reduced.

[0204] Note that the shape of the first connector 46 and the second connector 97 can be changed appropriately.

[0205] (Variation of the second embodiment)

[0206] The following are variations of the second embodiment. These variations can be implemented by combining them with each other where appropriate. Furthermore, the following variations can be implemented by appropriately combining them with the first embodiment.

[0207] (First variant)

[0208] Reference Figures 24 to 26 Describe the first variant of the DC piping system 100.

[0209] The first connector 46 is not limited to being mounted on the main body 42 of the power supply component, such as Figure 24 As shown, the first connector 46A can also be provided on the wire 47 leading out from the power supply component body 42 of the power supply component 4C.

[0210] Here, we will refer to Figure 25 and 26 An example describing the specific construction of power supply component 4C. Note that... Figure 25 and Figure 26The power supply component 4C shown is the first power supply component connected to the right end 31A, which is the right end of the DC pipe 3. However, the power supply component 4C can be the second power supply component connected to the left end 31B, which is the left end of the DC pipe 3.

[0211] The power supply component 4C includes an outer box 41, a power supply component body 42, and two contacts 44 (including a first contact 44A and a second contact 44B).

[0212] The power supply component body 42 has a cuboid shape, wherein its left-right dimensions are larger than its front-back and top-bottom dimensions. The power supply component body 42 has a rear first block 421 and a front second block 422. The first block 421 and the second block 422 are joined together with screws 425 to form the power supply component body 42. The power supply component body 42 accommodates two contacts 44 (including a first contact 44A and a second contact 44B). One end of the power supply component body 42 in the left-right direction is inserted into the DC conduit 3.

[0213] Viewed from the right, the outer box 41 is a C-shaped cuboid. The outer box 41 is attached to the power supply component body 42 using screws 426 to cover the portion of the power supply component body 42 exposed from the DC conduit 3.

[0214] In the power supply component body 42, a wire 47 is introduced into the power supply component body 42 from a second end opposite to the first end into which the DC conduit 3 is inserted. The wire 47 has two conductors 471 and 472, conductor 471 being soldered to a first contact 44A and conductor 472 being soldered to a second contact 44B.

[0215] The first connector 46A is connected to the wire 47. The first connector 46A is a bipolar connector.

[0216] The second connector 97, located on the wire W3 of the AC adapter 96, is connected to the first connector 46A. Because the first connector 46A is provided with a structure to prevent it from connecting to the second connector 97, which has the opposite polarity, the possibility of the first connector 46A being incorrectly connected to the second connector 97 during field installation is reduced.

[0217] Furthermore, the first connector 46A is connected to the power supply component body 42 via a wire 47, and the two conductors 471 and 472 of the wire 47 are pre-connected to the first contact 44A and the second contact 44B. Therefore, if the first connector 46A of the power supply component 4 is connected to the second connector 97 of the AC adapter 96 at the construction site, DC voltage is applied to the first conductive strip 32A and the second conductive strip 32B included in the DC conduit 3 with the correct polarity, thus reducing the possibility of incorrect construction at the construction site.

[0218] Please note, Figure 25 and 26 The first connector 46A shown is an example and can be modified as needed.

[0219] (Second variant)

[0220] Reference Figures 27 to 33 Describes the second variant of the DC piping system 100.

[0221] In the first and second embodiments described above, the protrusion 35, serving as an anti-connection structure, is provided on the rear surface of the DC pipe 3. However, the anti-connection structure is not limited to being provided on the rear surface of the DC pipe 3. As long as the shape of the assembly portion of the DC pipe 3 into which the power supply component 4 is assembled is asymmetrical with respect to the centerline L1, the anti-connection structure can be provided inside the DC pipe 3 in a portion other than the rear surface.

[0222] Figure 27 This is a side view of DC pipe 3 viewed from the right.

[0223] DC pipe 3 has a pipe body 31 and two conductive strips 32 (first conductive strip 32A and second conductive strip 32B).

[0224] The pipe body 31 includes a first metal guide rail 311 and two second synthetic resin guide rails 312. On the upper surface of the first guide rail 311, an attachment groove 3112 for mounting the second guide rails 312 is provided on the rear side, and a mounting part 3111 is provided on the front side. Similarly, the lower surface of the first guide rail 311 is provided with an attachment groove 3112, the second guide rails 312 are attached to the rear side of the attachment groove, and the mounting part 3111 is on the front side.

[0225] Each of the two attachment slots 3112 is provided with retaining claws 3116 and 3117 for retaining the second guide rail 312, and the second guide rail 312 is attached in the attachment slot 3112 because the retaining claws 3116 and 3117 contact the corner of the second guide rail.

[0226] The two mounting portions 3111 are recesses, and the two ribs 532 of the adapter 5A connected to the DC conduit 3 are inserted into the two mounting portions 3111. Furthermore, the two ribs 4211 and 4212 of the power supply member 4 attached to the DC conduit 3 are inserted into the two mounting portions 3111. In the two mounting portions 3111, the lower mounting portion 3112 is provided with a protrusion 3115 as an anti-connection structure.

[0227] The power supply component 4 includes a first power supply component 4A attached to a first end 31A on the right side of the DC channel 3 and a second power supply component 4B attached to a second end 31B on the left side of the DC channel 3.

[0228] The front part of the main body 42 of the first power supply component 4A is provided with a downwardly protruding rib 4211 and an upwardly protruding rib 4212 when attached to the first end 31A of the DC pipe 3 (see...). Figures 28 to 30 Similarly, the front part of the power supply component body 42 of the second power supply component 4B is provided with a downwardly protruding rib 4211 and an upwardly protruding rib 4212 when attached to the second end 31B of the DC pipe 3 (see...). Figures 31 to 33 Each of the first power supply component 4A and the second power supply component 4B has a recess 4213 on the rear surface of the rib 4211, and a protrusion 3115 provided on the mounting part 3111 is inserted into the recess 4213.

[0229] Therefore, when attempting to attach the first power supply component 4A to the second end 31B on the left side of the DC conduit 3, the downward-pointing rib 4212 of the first power supply component 4A contacts the protrusion 3115 of the mounting portion 3111, thus preventing the first power supply component 4A from being attached to the second end 31B. Furthermore, when attempting to attach the second power supply component 4B to the first end 31A on the right side of the DC conduit 3, the downward-pointing rib 4212 of the second power supply component 4B contacts the protrusion 3115 of the mounting portion 3111, thus preventing the second power supply component 4B from being attached to the first end 31A. Therefore, the possibility of DC voltage being applied to the first conductive strip 32A and the second conductive strip 32B of the DC conduit 3 with incorrect polarity can be reduced.

[0230] Furthermore, since the protrusion 3115, which serves as an anti-connection structure, is provided inside the assembly portion 3111, it has the advantage that, compared to the case where the protrusion 35, which serves as an anti-connection structure, is provided on the rear surface of the DC pipe 3 as in the above embodiment, the protrusion 3115 is less likely to interfere when forming the retaining claws 3116 and 3117.

[0231] Note that the anti-connection structure described in the second variation can also be applied to the DC piping system 100 of the first embodiment described above.

[0232] (Third variant)

[0233] Reference Figure 34 The power supply component 4 is described in the DC piping system 100 of the third variant.

[0234] The power supply component 4 included in the third variant of the DC piping system 100 differs from that in the second variant in that it is directly connected to the AC adapter 96 via wire 47.

[0235] Since the power supply component 4 is directly connected to the AC adapter 96 via wire 47, no field connection connector is required, and when the plug of the AC adapter 96 is connected to the power outlet, DC voltage is supplied to the first conductive bar 32A and the second conductive bar 32B of the DC conduit 3. Therefore, the possibility of DC voltage being applied to the first conductive bar 32A and the second conductive bar 32B of the DC conduit 3 with incorrect polarity can be reduced.

[0236] (Summary)

[0237] As described above, the DC conduit system (100) of the first aspect includes a DC conduit (3) and a power supply component (4). The DC conduit (3) holds a first conductive bar (32A) on the positive side and a second conductive bar (32B) on the negative side to which a DC voltage is to be applied. A receiving device (5) that receives DC voltage via the first conductive bar (32A) and the second conductive bar (32B) can be connected to the DC conduit (3) at any position along the length of the first conductive bar (32A) and the second conductive bar (32B). The power supply component (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 (32), and is connected to one end of the DC conduit (3) along the length. The other end of the DC conduit (3) along the length is provided with an anti-connection structure (35, 3115) that prevents the power supply component (3) from connecting to the other end of the DC conduit (4) by contacting at least a portion of the power supply component (4). The power supply component (4) has a first terminal (43A), a second terminal (43B), and a power supply component body (42) that holds the first terminal (43A) and the second terminal (43B). The first terminal (43A) is electrically connected to a first contact (44A) and can be connected to the positive side wire (W1) of the DC power supply section (PE1) that outputs DC voltage. The second terminal (43B) is electrically connected to a second contact (44B) and can be connected to the negative side wire (W2) of the DC power supply section (PE1). The power supply component body (42) is provided with polarity display portions (M1, M2) that display the polarity of the first terminal (43A) and the second terminal (43B).

[0238] Based on this, the possibility of applying DC voltage with incorrect polarity to the first conductive strip (32A) and the second conductive strip (32) can be reduced.

[0239] The second aspect of the DC conduit system (100) includes a DC conduit (3) and a power supply component (4). The DC conduit (3) holds a first conductive bar (32A) on the positive side and a second conductive bar (32B) on the negative side to which a DC voltage is to be applied. A receiving device (5) that receives DC voltage via the first conductive bar (32A) and the second conductive bar (32B) can be connected to the DC conduit (3) at any position along the length of the first conductive bar (32A) and the second conductive bar (32B). The power supply component (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), and is connected to one end of the DC conduit (3) along its length. The other end of the DC conduit (3) is provided with an anti-connection structure (35, 3115) that prevents the power supply component (3) from connecting to the other end of the DC conduit (4) by contacting at least a portion of the power supply component (4). The power supply component (4) has a first connector (46, 46A). A second connector (97) disposed on the wire (W3) of the DC power supply section (PE1) from which the DC voltage is output can be connected to the first connector (46, 46A). When the second connector (97) is connected to the first connector (46, 46A), the DC voltage is applied from the DC power supply section (PE1) to the first contact (44A) and the second contact (44B).

[0240] Based on this, the possibility of applying DC voltage with incorrect polarity to the first conductive strip (32A) and the second conductive strip (32B) can be reduced.

[0241] In the DC conduit system (100) of the second aspect, the power supply component (4) has a power supply component body (42) that holds a first contact (44A) and a second contact (44B). A first connector (46A) is provided on a wire (47) extending from the power supply component body (42). The first connector (46A) is electrically connected to the first contact (44A) and the second contact (44B) via the wire (47).

[0242] Based on this, the possibility of applying DC voltage with incorrect polarity to the first conductive strip (32A) and the second conductive strip (32B) can be reduced.

[0243] In the DC conduit system (100) of the fourth aspect of any of the first to third aspects, the DC conduit (3) is provided with anti-connection structures (35, 3115) on the entire length of the first conductive strip (32A) and the second conductive strip (32B).

[0244] According to this aspect, even if the DC pipe (3) is cut to an appropriate size, the anti-connection structure (35, 3115) can be set at both ends of the DC pipe (2) in the length direction.

[0245] In the DC conduit system (100) of the fifth aspect of any of the first to fourth aspects, the anti-connection structure (35, 3115) includes protrusions (35, 3115) provided on the DC conduit (3). When viewed from the length direction, the shape of the assembly portion of the DC conduit (4) to which the power supply component (4) is assembled is asymmetrical with respect to the centerline (L1) of the DC conduit (3) in a direction orthogonal to the length direction and the direction in which the power receiving device (5) is attached to the DC conduit (1).

[0246] Based on this, the possibility of the power supply component (4) being incorrectly attached to the end opposite to the intended end can be reduced.

[0247] In the DC conduit system (100) of the sixth aspect of any of the first to fifth aspects, the power supply component (4) includes a first power supply component (4A) and a second power supply component (4B). The first power supply component (4A) is connected to the first end (31A) of the DC conduit (3) in the length direction of the first end (31A) and the second end (31B), while the second power supply component (4B) is connected to the second end (31B). Anti-connection structures (35, 3115) prevent the first power supply component (4A) from being connected to the second end (31B) and prevent the second power supply component (4B) from being connected to the first end (31A).

[0248] According to this aspect, it is possible to prevent the first power supply component (4A) from being incorrectly connected to the second end (31B) and to prevent the second power supply component (4B) from being incorrectly connected to the first end (31A).

[0249] In the DC conduit system (100) of the seventh aspect of any of the first to sixth aspects, the DC conduit system further includes a notification section (80) configured to notify the application status of the DC voltage to the first contact (44A) and the second contact (44B).

[0250] According to this aspect, when a DC voltage with incorrect polarity is applied to the first conductive strip (32A) and the second conductive strip (32B), the worker can confirm the construction error based on the notification content provided in the notification section (80). Therefore, the possibility of applying DC voltage with incorrect polarity to the first conductive strip (32A) and the second conductive strip (32B) can be reduced.

[0251] In the DC conduit system (100) of the seventh aspect and the eighth aspect, the notification part (80) includes a light source (81). The light source (81) is lit when a DC voltage is applied to the first contact (44A) and the second contact (44B) such that the voltage of the second contact (44B) is higher than the voltage of the first contact (44A).

[0252] According to this aspect, since the light source (81) is lit, the worker can confirm that a DC voltage is being applied to the first conductive strip (32A) and the second conductive strip (32B) with the wrong polarity. If a DC voltage is applied to the first conductive strip (32A) and the second conductive strip (32B) with the correct polarity, the light source (81) is turned off, thus reducing power consumption.

[0253] The DC conduit (3) of the ninth aspect is the DC conduit (3) included in the DC conduit system (100) of any of the first to eighth aspects.

[0254] Based on this, the possibility of DC voltage being applied to the first conductive strip (32A) and the second conductive strip (32B) of the DC pipe (3) with the wrong polarity can be reduced.

[0255] The power supply component (4) of the tenth aspect is the power supply component (4) included in the DC conduit system (100) of any one of the first to eighth aspects.

[0256] Based on this aspect, the possibility of applying DC voltage with incorrect polarity to the first conductive bar (32A) and the second conductive bar (32B) of the DC pipe (3) to which the power supply component (4) is connected can be reduced.

[0257] The power supply system (PS1) of the eleventh aspect includes a DC conduit system (100) of any one of the first to eighth aspects and a DC power supply section (PE1). The DC power supply section (PE1) converts the AC voltage input from the AC power source (91) into a DC voltage and outputs the DC voltage to the power supply component (4).

[0258] Based on this, the possibility of applying DC voltage with incorrect polarity to the first conductive strip (32A) and the second conductive strip (32B) can be reduced.

[0259] The construction according to aspects two through eight is not necessary for the DC piping system (100) and can be appropriately omitted. Furthermore, aspects nine and ten are aspects that can be implemented independently and can be applied to the DC piping system (100) of any of aspects one through eight.
