It is a disassembled perspective view of a box.

  The underfloor wiring system 1 according to the present embodiment is formed in a space between a lower floor 9 and an upper floor (floor panel) 10 installed on the lower floor 9 with a space therebetween. As shown in FIG. 1, this space is a box having a floor panel for forming the upper floor 10 on a support (not shown) arranged on the lower floor 9 as shown in FIG. Or the like (not shown) may be arranged on the lower floor 9. FIG. 1 shows a form in which only the power supply line is routed in the space between the upper floor 10 and the lower floor 9, but communication lines such as LAN cables and telephone lines are also routed in this space. can do. Further, a floor carpet or the like may be appropriately laid on the upper floor 10.

  This underfloor wiring system 1 has two power supply systems (A system and B system). For each power supply system, the main harness 3, joint box 4, harness cap 8, branch cable 7, power tap 5, floor A power supply line is constructed using wiring equipment such as the outlet 6.

  The power supply system can be arbitrarily determined according to the application. Specifically, depending on the power management method and power supply method, for example, a system using an uninterruptible power supply, a system using a power switching device, a system connected to a commercial power supply, etc. can be set. it can. Further, a framework may be set according to the user, the device used, the number of devices used, the total power consumption of the device, and the like, and a power supply system may be set for each framework.

  In the example of FIG. 1, so-called cascade connection is employed for each power supply system. That is, a plurality of joint boxes 4 are connected in cascade from the distribution board 2 for each power system via the trunk harness 3, and the power taps 5 and floor outlets are connected to the joint boxes 4 via the branch cables 7. An output wiring tool such as 6 is connected.

  The joint box 4 includes a plurality of connectors, and functions as a relay unit that connects the main line harness 3 and the branch cable 7 far from the power source to the main line harness 3 near the power source (not shown). The branch cable 7 is attached with a harness cap 8 as a connector.

  A wiring device such as the power tap 5 and the floor outlet 6 is connected to the end side of the branch cable 7. In addition, it is convenient to attach and integrate the branch cable 7 and the harness cap 8 to the power tap 5 and to set a plurality of specifications with different lengths of the branch cable 7.

  And in this embodiment, the discriminating tool for identifying a power supply system is detachably attached to the wiring device. Specific examples will be described below.

  FIGS. 2 and 3 are examples in which the identification tools 11 and 12 are detachably attached to the power tap 5 as a wiring instrument.

  The identification tool 11 is formed in a substantially rectangular frame shape in plan view, and is fitted into (inserted into) an annular recess 5b in the plan view substantially rectangular shape formed around the insertion block 5a of the power tap 5. . In this case, the identification tool 11 is formed of an elastic member such as a resin, and an engagement mechanism (not shown) for engaging the identification tool 11 and the main body of the power strip 5 is appropriately provided or fitted. It is preferable to adjust the mating dimension so that the discriminator 11 can be easily attached and detached with fingers and tools and can be held more securely.

  Moreover, the identification tool 12 is formed in a substantially rectangular plate shape, and is fitted into a shallow concave portion 5c having a substantially rectangular shape in plan view formed on the surface of the power tap 5 (the surface on the side where the insertion port is disposed). (Fitted) In this case, the identification tool 12 is formed of an elastic member such as a resin, and a mechanism for appropriately engaging the identification tool 12 and the main body of the power strip 5 (for example, formed at both ends in the longitudinal direction of the identification tool 12). The claw 12a and the groove 5d for fitting the claw 12a formed at both ends in the longitudinal direction of the recess 5c are provided, and the fitting dimension is adjusted, so that the identification tool 12 can be attached and detached more easily with fingers or tools. It is preferable to be able to hold it more reliably.

  All or a part of these identification tools 11 and 12 are colored according to the power supply system. Specifically, for example, the power system identification tools 11 and 12 connected to the uninterruptible power supply are green, and the power system identification software 11 and 12 connected to a normal commercial power supply are red. In this case, the user can recognize that the power supply may be stopped for the power tap 5 to which the red identification tools 11 and 12 are attached, and the green identification tools 11 and 12 are attached. It can be recognized that the power supply tap 5 is less likely to stop power supply. In addition, since one color is assigned to one power supply system, in the example shown in FIGS. 2 and 3, the identification tools 11 and 12 have the same color.

  Moreover, if the display element (a character, a pattern, a pattern, a stamp, etc.) corresponding to a power supply system is provided on the surface like the discriminator 12, the discriminability can be further improved.

  Then, by making the discriminating tools 11 and 12 detachable from the power strip 5, the discriminating tools 11 and 12 can be used as the power strip 5 for another power supply system simply by changing the discriminating tools 11 and 12 to those of different colors. However, it goes without saying that it is necessary to change the connection source of the power strip 5 when the replacement is made.

  4 and 5 show an example in which the identification tool 13 is detachably attached to a power strip 5A similar to the power strip 5 described above. This power strip 5A can be provided in place of the power strip 5 of the underfloor wiring system 1 shown in FIG.

  The identification tool 13 is formed in the shape of an elongated square bar, and is fitted (fitted) into a notch-shaped recess 5f formed in the peripheral edge (corner part) 5e of the surface of the power tap 5A. In this case, the identification tool 11 is formed of an elastic member such as resin, and an engagement mechanism (not shown) for engaging the identification tool 13 and the main body of the power tap 5 is provided or fitted as appropriate. It is preferable to adjust the mating dimension so that the discriminating tool 13 can be attached and detached more easily with fingers and tools and can be held more securely. In the case of this example, a plurality of elongated identification tools 13 are arranged in tandem along the long peripheral edge of the surface of the power tap 5A. By doing so, the handling can be facilitated as compared with the case where one long discriminator is provided, and the discriminability of the power supply system can be improved as compared with the case where the length is short. In addition, there is an advantage that it is less likely to come off than when the length is long.

  The identification tool 13 is also color-coded for each power supply system, as with the identification tools 11 and 12. In this case as well, the identification tool 13 can be attached to and detached from the power strip 5A so that the identification tool 13 can be used as a power strip 5A for another power system simply by changing the identification tool 13 to a different color. Become.

  6 and 7 show an example in which the identification tool 15 is detachably attached to the power tap 5B similar to the power taps 5 and 5A. This power strip 5B can be provided in place of the power strip 5 of the underfloor wiring system 1 shown in FIG.

  On the surface of the power tap 5 </ b> B, a display lamp 14 having a substantially rectangular shape in a plan view showing an energized state is provided. That is, the identification tool 15 is formed of a resin that is colored and transparent and has elasticity, and a mechanism for appropriately engaging the identification tool 15 and the main body of the power strip 5B (for example, at both ends in the longitudinal direction of the identification tool 15). The formed claw 15a and the groove 14a into which the claw 15a formed adjacent to both ends in the longitudinal direction of the indicator lamp 14 is provided, or the fitting dimension is adjusted, and the discriminating tool 15 is formed by fingers or tools. It is preferable to be able to attach and detach easily and to be held more securely.

  The identification tool 15 is also color-coded for each power supply system, similar to the identification tools 11-13. In this case as well, the identification tool 13 can be attached to and detached from the power strip 5B, so that the identification tool 13 can be used as a power strip 5B for another power supply system by simply replacing the identification tool 13 with a different color. Become.

  8 and 9 are examples in which the identification tool 16 can be detachably attached to a joint box 4A similar to the joint box 4 described above. This joint box 4A can be equipped in place of the joint box 4 of the underfloor wiring system 1 shown in FIG.

  The identification tool 16 is configured as a cover on the outer surface of the joint box 4A. That is, the identification tool 16 is formed of an elastic resin or a metal plate, and a mechanism (not shown) for appropriately engaging the identification tool 16 and the main body of the joint box 4A is provided. It is preferable to adjust the dimensions so that the identification tool 16 can be attached and detached more easily with fingers and tools and can be held more securely. In this example, both ends in the longitudinal direction of the identification tool 16 are bent to form a pair of arm portions 16a, and the pair of arm portions 16a sandwich the pair of side walls 4a of the joint box 4A. When the joint box 4A is screwed to any fixing member with a screw (not shown) inserted into the through hole 4b, the screw is also inserted into the through hole 16b provided in the identification tool 16. The identification tool 16 is preferably fastened together.

  The identification tool 16 is also color-coded for each power supply system, similar to the identification tools 11 to 13 and 15. In this case as well, the identification tool 16 can be attached to and detached from the joint box 4A so that the identification tool 16 can be used as a joint box 4A for another power supply system simply by replacing the identification tool 16 with a different color. Become.

  Furthermore, as shown in FIG. 8, when the identification tool 17 that holds the branch cable 7 in the vicinity of the harness cap 8 is used, if the identification tool 17 has the same color as the identification tool of the power strip in advance, the power strip The power line extending from the joint box 4A to the power tap can be more easily constructed simply by matching the colors of the discriminating tool 16 and the discriminating tool 17 without checking the discriminating tool. Such a configuration is particularly effective when the length of the branch cable 7 is long. As the identification tool 17, a bushing attached to the branch cable 7, a detachable noise filter, or the like can be used.
