Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a wiring device.

[Background technology]

Recently, floors with a double floor structure, in which floor panels and the like are placed at regular intervals on the top surface of the foundation (foundation surface), have come into use. This is due to the following circumstances.

In recent years, OA equipment has rapidly become popular, and even small offices are using a considerable number of OA equipment.

There are few power outlets in existing old buildings, so
This has been countered by using cordless wiring for table taps, etc., but this method is extremely dangerous as the cords are intertwined on the floor.

In order to solve this problem, we installed a floor panel on top of the existing concrete floor using spacers, and installed a wiring cable in the space between the concrete floor and the floor panel.
A wiring device to which this cable is connected is placed at a desired location on the floor panel, and the plug of the OA equipment is connected to this wiring device.

A wiring device shown in FIG. 3 has also been developed for use in such a double floor structure.

As shown in the figure, this wiring device includes a box 1' that is fitted into an opening provided in the floor of a floor panel 9 suspended on a base surface 1°0. Box 1' has an opening on the top surface.

This top opening is covered with a lid 2. The lid 2 and the box 1' are fixed with screws 70.

Inside the box 1', there are a plug holder for strong electricity (heavy electricity connection device) 5 and a plug holder for light electricity (connection device for light electricity) 6. It is stored facing the inside of 1. An electric outlet etc. is inserted into the strong electric plug receiver 5,
A telephone (information) jack or the like is inserted into the light electrical plug receiver 6. These heavy electric power plug receiver 5 and low electric power plug receiver 6 are connected to the appliance fixing fitting 3 fixed to the box 1'.
It is mounted at an angle.

A hole 23 is formed in the center of the lid 2 to allow a connected device to be inserted into the box 1' from the outside through the top opening. ing. This opening 23 is normally closed by a door 21 which is attached to the lid frame 26 via a hinge portion 22 so as to be freely openable and closable (in the figure, the door 21 is shown in an open state). ). A notch 24 is formed in the free end of the opening/closing door 21, so that the cord of the connected appliance connected to the heavy electrical plug receiver 5 or the light electrical plug receiver 6 can be pulled out when the opening/closing door 21 is closed. ing.

In this wiring device, the connection of connected devices such as plugs is made inside the box, and the connected devices are not exposed or protrude from the floor, so the appearance is good and the connected devices do not get in the way. be.

A height adjustment bolt (
Height adjustment means) 90' are passed through four locations. The box 1' is supported on the base surface 100 via this bolt 90', and its height can be adjusted by rotating the bolt 90'. After adjusting the height, bolt 90'
The rotation of the nut 91' is locked to prevent loosening.

In this wiring device, the height of the box 90' is adjustable, so the lid 2 covering the top opening of the box 1' is installed on the floor panel 9 forming the floor. This makes it possible to prevent the lid 2 from being dented even if the floor panel 9 is stepped on, even if the floor panel 9 is of low strength.

However, in this wiring device, since the bolt 90' and nut 91' for adjusting the height are provided on the bottom surface 19 of the box 1', it is difficult to adjust the height by rotating the NAND 91'. Moreover, from the bottom surface 19)
0' and the nut 91' protrude, which obstructs the connection of the connected appliance to the high-power plug receiver 5 or the low-power plug receiver 6, and also prevents the box 1' from being inserted.
The depth of the cord became shallow, making it impossible to store the extra length of the cord of the connected device.

[Purpose of the invention]

In view of the above circumstances, the present invention takes advantage of the advantages of the newly developed wiring device described above, allows for easy height adjustment, does not get in the way when connecting a connected device to a connected device, and provides It is an object of the present invention to provide a wiring device that can sufficiently accommodate the extra length of the cord of a connecting device.
