Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of a wiring duct used for attaching an outlet to a building structure and wiring the outlet.

(Prior art) Conventionally, when installing an outlet on a building structure, such as a wall, the outlet is directly attached to the wall with screws, and then the connection between the outlet and the power line wired on the floor or ceiling is connected. Connections are made using electric wires that pass through a gutter that is attached to the wall with screws or double-sided adhesive tape, but in this case, due to the structure of the wiring using the gutter and the outlet, it must be connected to a wall far away from the corner of the room. It is installed in a relatively conspicuous position, and as a practical matter, it is not possible to match the wiring gutters and outlets with the wide variety of interior designs. Not only does this tendency become stronger as the number of wires increases, but as the number of wires increases, the wire gutter becomes more likely to come off the wall, etc., and construction becomes difficult. When wiring power lines and signal lines, although both lines are insulated and isolated from each other, the signal lines must be specially magnetically shielded to prevent electromagnetic interference between the two lines. This not only increases costs, but also makes the line gutter thicker and impractical, resulting in no countermeasures against electromagnetic interference, and noise is superimposed on the signal line due to the influence of line noise and unnecessary radiation waves on the power line. There were some drawbacks.

(Problems to be Solved by the Invention) The present invention has a relatively small size, does not damage the interior design, is easy to install even when the number of wiring lines and outlets increases, and is equipped with a special magnetic shielding device. To provide a wiring duct which can take measures against electromagnetic interference between power lines and signal lines without causing interference.

(Means for Solving the Problem) Therefore, in the present invention, the duct main body installed along the structure of the building has a cross-sectional shape of a substantially right triangular shape corresponding to the corner shape of the structure, and Forming a right-angled triangle so that the hypotenuse surface is an open surface, forming an outlet attachment means for removably attaching an outlet having the open surface as the insertion surface at any position in the longitudinal direction of the duct body, Further, a removable wiring cover is provided on the open surface of the duct body, and furthermore, at least one corner between two adjacent sides of the right triangle of the duct body is provided with a wiring cover that holds the electric wire passing through the corner and Forming a holding plate attachment means to which a holding plate formed of an electromagnetic wave shielding material is attached to serve as a magnetic shield for electric wires, and adjacent to a right triangle formed by the holding plate and two corners of the duct body. By forming two sides of the duct with electromagnetic shielding members, the right triangular structure at the corners is changed to a two-layer structure of the duct body and the electromagnetic shielding member,
It is to configure a wiring duct.

In addition, the duct body that is attached along the structure of the building has a cross-sectional shape that corresponds to the corner shape of the structure, and has a substantially right triangular shape,

By forming two adjacent sides of the electromagnetic wave shielding member, the right triangular structure at the corner becomes a two-layer structure of the duct body and the electromagnetic wave shielding member, and the duct body is further attached to the end face of the duct body. The end cover is made of an electromagnetic shielding material in order to have a magnetic shielding effect on the electric wire passing through the corner of the duct body, and when the end cover is attached to the end face of the duct body, the end cover is tightened to prevent the electromagnetic shielding from occurring. The wiring duct is configured so that the material part is tightened with a metal screw that also serves as grounding.
