  Next, the installation procedure of the floor wiring device 1 will be described. In the following description, it is assumed that the box 2 to which the embedded cover 3 is attached is embedded in a predetermined position of the concrete floor 100. Further, description will be made assuming that the wiring fixture block 4 is prepared in which the wiring fixture 8 is attached to the attachment frame 9 and the attachment frame 9 is fixed to the attachment plate 411 using the attachment screw 17.

  First, the operator pulls an electric wire (not shown) drawn into the box 2 through the conduit 110 into a wiring hole (not shown) on the back surface of the wiring device 8. The ground wire 18 drawn into the box 2 through the conduit 110 is screwed to the bottom surface of the box 2. Thereafter, the operator attaches the wiring device block 4 to the embedded cover 3 using the mounting screws 13 while the wiring device block 4 is housed in the box 2 through the opening 301 of the embedded cover 3. At this time, the wiring device block 4 is arranged so that the longitudinal direction of the mounting plate 411 of the mounting bracket 41 and the longitudinal direction of the opening 301 of the embedded cover 3 are the same direction.

  Next, the operator screws the adjustment screw 14 inserted through the insertion hole 502 of the adjustment plate 5 into the screw hole 305 of the embedded cover 3. At this time, the operator adjusts the height of the adjusting screw 14 according to the thickness of the surface material (for example, tile carpet) laid on the floor upper surface. Further, the operator attaches the adjustment plate 6 to the adjustment plate 5 using the attachment screw 15. When the adjustment plate 6 is attached to the adjustment plate 5, the head of the adjustment screw 14 is sandwiched between the adjustment plate 5 and the adjustment plate 6, and the upper adjustment plate 6 is at a height position determined by the screwing amount of the adjustment screw 14. Retained.

  Finally, the operator attaches the floor plate 7 to the adjustment plate 6 using the attachment screws 16. At this time, the floor plate 7 is attached to the adjustment plate 6 so that the axial direction of the door 71 and the width direction of the opening 301 of the embedded cover 3 are the same direction and the wiring chip 72 is on the conduit 110 side. It is done. The installation of the floor wiring device 1 is completed by the above procedure. Here, when the floor wiring device 1 is installed on the floor, the upper surface of the main body 60 of the adjustment plate 6 is in surface contact with the lower surface of the plate frame 70 of the floor plate 7. And in the state which installed the wiring apparatus 1 for floors, the wiring fixture block 4 is arrange | positioned so that the said functional surface may face diagonally upward.

  Next, a procedure for connecting a power plug to the wiring device 8 will be described. First, the user opens the door 71 by sliding the open / close button provided on the upper surface of the door 71 of the floor plate 7 in the opening direction, and supplies power to the insertion port 81 of the wiring device 8 housed in the box 2. Insert the plug. Subsequently, the user moves the wire tip 72 in the opening direction with the door 71 open, and then closes the door 71 with the wire tip 72 open. At this time, an electric wire (not shown) connected to the power plug is protected by the bush 74 and led out to the outside through the opening of the wiring chip 72.

  A procedure for removing the power plug from the wiring device 8 will be described. First, the user opens the door 71 by sliding the open / close button provided on the upper surface of the door 71 of the floor plate 7 in the opening direction, and pulls out the power plug from the insertion port 81 of the wiring device 8. Subsequently, the user moves the wire chip 72 in the closing direction while keeping the door 71 open, and then closes the door 71. In this way, in a state where the floor wiring device 1 is not used, the wiring chip 72 does not get in the way by closing the wiring chip 72.

  Finally, a procedure for removing the wiring device 8 from the mounting device for repair or the like will be described. However, it is assumed that the floor plate 7, the adjustment plates 5 and 6, and the power plug have already been removed. The mounting screw 13 is removed, and the wiring device block 4 is taken out. Using a jig such as a screwdriver from the front of the mounting plate 411 of the mounting bracket 41 mounted on the front surface of the mounting frame 9, it is inserted between the vertical frame 91 and the release piece 94, and the release piece 94 is inserted into the vertical frame 91. Press outward to pull away from. In a state where the release piece 94 is being pressed, the attachment claws 821 of the wiring device 8 are respectively extracted from the attachment holes 93 on one side of the release piece 94 and then attached to the attachment holes 93 on the other side of the attachment frame 9. Remove 821 respectively.

The mounting device for a wiring device of the present embodiment includes a mounting frame 9 that detachably holds the wiring device 8, a mounting bracket 41 that holds the mounting frame 9, and an embedded member (embedding for embedding the mounting bracket 41 under the floor. Cover 3 and adjusting plates 5 and 6). The attachment frame 9 is provided with an detachment portion (release piece 94) configured so that the wiring device 8 can be removed when operated from the front at the end (vertical frame 91). The embedding member is configured such that the wiring device 8 faces the opening 101 provided in the floor 100. The mounting bracket 41 has a mounting plate 411 that is mounted on the front surface of the mounting frame 9. The attachment plate 411 is configured such that the removal portion can be operated from the front of the attachment frame 9.
