Description

[Detailed Description of the Invention] [Technical Field] The present invention provides insulation between low-power wiring devices such as TV terminals and telephone wiring devices and high-power wiring devices such as switches and outlets in the same wiring device box. This invention relates to an insulating separator for separation.

[Background technology]

Generally, when a strong electric wire and a weak electric wire are wired in the same box, it is stipulated that they must be separated by a strong insulating partition. For example, Fig. 1a is a perspective view of a conventional information and power supply type wiring equipment box, and as shown in Fig. 1b, in the center of the wiring equipment box 1,
An insulating plate supporting rib 3 is formed for mounting an insulating plate 2 for insulating and separating information wiring equipment and power supply wiring equipment. 4 is wiring equipment box 1
This is a hole provided at the bottom of the wall, and is used for positioning when the wiring equipment box 1 is embedded in the wall surface and concrete is poured. In such a conventional example, when connecting a power outlet and an information outlet such as a TV terminal, a standard wiring equipment box cannot be used, and the insulating plate supporting rib 3 as described above is used. This method requires a special wiring device box 1, and has the disadvantage that the position where the insulating plate 2 is fixed is determined in advance and cannot be fixed at an arbitrary position. Furthermore, as shown in FIG. 1b, when a coating allowance cover 5 is added to the front opening of the wiring equipment box 1, there is a drawback that the insulating plate 2 cannot be attached or removed after installation. It was hot. In other words, the paint allowance cover 5 is used to reduce the front opening area of the wiring equipment box 1 in order to prevent the wall material 6 from entering the inside of the wiring equipment box 1 when painting the wall. When the cover 5 is added, there is a drawback that the insulating plate 2 cannot be attached or detached. In addition, in such a conventional example, since the size of the insulating plate 2 in the height direction cannot be adjusted at all, for example, if the wiring equipment box 1 is buried too deep in the wall surface, the wiring equipment box 1 may be There was a problem in that a gap was created between the front plate covered on the front side and the upper end surface of the insulating plate 2, making it impossible to completely insulate and separate the wiring block for low electric current and the wiring block for heavy electric current. .

[Purpose of the invention]

The present invention has been made in view of the above-mentioned points, and uses a standard wiring equipment box to connect a wiring block for heavy electricity and a wiring block for light electricity, without using a special wiring equipment box. In addition to making it possible to connect them in an insulated state,
The object of the present invention is to provide an insulating separator whose size in the height direction can be adjusted to some extent.

[Disclosure of the invention]

Hereinafter, the configuration of the present invention will be described with reference to illustrated embodiments. As shown in FIGS. 2 to 4, there is a wiring device that connects and houses a wiring device 7 for power supply and a wiring device 8 for information. In the insulating separator installed in the box 1 so as to partition both the wiring devices 7 and 8, the periphery is slightly smaller than the cross-sectional shape of the inside of the wiring device box 1 in the direction in which both the wiring devices 7 and 8 are partitioned.

The extension portion 12 is provided with notch grooves 11 at appropriate intervals as described above, making it possible to adjust the size of the insulating separator in the height direction.

[Effects of the Invention] The present invention is configured as described above, and a wiring equipment box for storing a wiring equipment for power supply and an information wiring equipment in conjunction with each other is provided with a wiring equipment box that partitions both wiring equipment. The insulating separator to be installed includes a flat portion having a peripheral edge shape slightly smaller than the cross-sectional shape of the inside of the wiring device box in the direction in which both wiring devices are partitioned, and a substantially Y-shaped branch from the peripheral edge of this flat portion. A flexible flange portion that extends to and from the inner bottom surface of the wiring device box and the inner surfaces of both ends in the partition direction, and a peripheral edge portion of the flat portion located on the opposite side from the inner bottom surface of the wiring device box. Since it is provided with a flexible extension part that extends and has notch grooves that serve as cutting lines at appropriate intervals in the extension direction,
The insulating separator can be attached using the elastic contact force of the flange without the need for ribs for supporting the insulating plate. Therefore, there is no need for a special wiring equipment box as in the past, and a standard wiring equipment box can be used. The insulating separator of the present invention has the effect of being able to connect an information wiring device and a power supply wiring device in an insulated and separated state, and the insulating separator of the present invention can be attached to a wiring device box by the elastic force of the flange portion. Since it is a type of wire, the mounting position can be set arbitrarily, and dimensional errors in the wiring equipment box can be absorbed. Furthermore, in the present invention, flexibility is provided by providing notch grooves extending from the peripheral edge of the plane part located on the opposite side of the inner bottom surface of the wiring equipment box and serving as cutting lines at appropriate intervals in the extending direction. By cutting the extending part at the notch groove, it is possible to adjust the size of the insulating separator in the height direction. Even if there is slight variation in the embedding depth, etc., there will be no gap between the front plate of the wiring equipment box and the insulating separator. In addition, in the insulating separator of the present invention, the flange portion that comes into elastic contact with the inner surface of the wiring equipment box has flexibility, and the peripheral edge shape of the flat portion is Since it is slightly smaller than the internal cross-sectional shape of the wiring equipment box, it has the effect that the insulating separator can be attached and removed even when a coating allowance cover is added to the front opening of the wiring equipment box to reduce the opening area.
