Description

[Detailed Description of the Invention] [Technical Field] The present invention is a system for storing low-power wiring devices such as TV terminals and telephone wiring devices together with high-power wiring devices such as switches and outlets in a wiring device box. This invention relates to an insulating separator for insulating and separating both wiring devices in a box.

[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.

A conventional wiring equipment box 1' using such an insulating separator is shown in FIGS. 1 and 2. In these figures, 1' is a wiring equipment box, and 2 is a coating allowance cover, which is used to prevent construction materials from entering the wiring equipment box when embedding the wiring equipment box in construction materials. Used to reduce the front opening area of the box. 3' is an insulating separator, 11 is a lip for supporting the insulating separator, 12 is a screw hole for fixing wiring equipment,
Reference numeral 13 denotes a hole provided in the back wall of the wiring equipment box, which is used for positioning when the wiring equipment box 1' is embedded in the wall surface and concrete is poured.

By the way, in such a conventional example, the insulating separator 3
Since the length in the depth direction of ' cannot be adjusted at all, for example, if the wiring equipment box 1' is buried too deep in the wall surface, the front plate that covers the front of the wiring equipment box 1' (not shown) and the front side (front side) end surface of the insulating separator 3, and the problem arises that the wiring block for low electric current and the wiring block for heavy electric current cannot be completely insulated and separated. there were.

In view of these circumstances, the applicant has developed an insulating separator that makes it possible to install the insulating separator into a standard wiring equipment box and also adapts to changes in the depth of embedding of the wiring equipment box. It has been developed. It is an insulating separator in which a cutoff line is provided on the peripheral edge of the main body except for the front side to make a joint of the depth and length. Although this insulating separator is excellent in solving the above-mentioned conventional problems, subsequent use experiments have revealed that there are some points that need to be improved. The problem is that a tool must be used to cut off the front portion of the insulating separator in order to adjust its length in the depth direction.

[Purpose of the invention]

In view of the above circumstances, this invention makes it possible to mount an insulating separator in a standard wiring equipment box, and also adapts to changes in the embedding depth of the wiring equipment box. The purpose of the present invention is to provide an insulating separator whose length can be easily adjusted by hand without using tools.

[Disclosure of the invention]

The present invention provides an insulating separator that is installed in a box that houses both a power supply wiring device and an information wiring device so as to partition the rewiring device, and has a plate-shaped main body, The gist of the insulating separator is that an appropriate number of perforation lines are provided on the front side of the separator for adjusting the depth and length, and the perforation lines have a notch at least at one end. be. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 3 shows how the insulating separator according to the invention is used, and FIG. 4 shows an embodiment of the same insulating separator. As shown in these figures, a hole 5 is made in the construction material 4, and a wiring equipment box l is embedded in the hole 5.

In the box 1, a wiring device 6 for power supply and a wiring device 7 for information are housed together. box 1
An insulating sehalator 3a is attached to the inner center so as to partition the rewiring device 6.7. This insulating separator has a plate-shaped main body part 31, and a substantially Y-shaped skirt part (also referred to as a flange part) 32 extending from the peripheral edge in the direction other than the front direction is elastically crimped to the inner surface of the box 1. are doing. On the front side of the plate-shaped main body part 31, three perforation lines 33 for adjusting the depth and length are formed in the horizontal direction at equal intervals. In this embodiment, the perforation line 33 is constituted by a groove. The perforation line 33 has a ■-shaped notch 34 at both ends thereof. The perforation line is further provided with two through holes 36 having notches 35 at both ends. And this through hole 3
6 becomes shorter from the upper perforation line 33 to the lower perforation line 33.

The skirt portion 32 and the main body portion 31 are made of flexible rubber, special soft vinyl chloride resin, or the like. Front part of main body part 31 (part with cutoff line) 31a
Since it is a cutout part, it needs to be flexible, but the inner part 31b
preferably has rigidity. Therefore, this part 31
b has a built-in rigid core. As this core, thermosetting resins, metal plates, different types of thermoplastic resins, etc. are used. Front part 31a and back bone 3
It may be separate from 1b. The height of the main body portion 31 is sufficient to accommodate the case where the wiring device box 1 is buried deep in the wall surface.The insulating separator according to the present invention has a cutout line formed on the front side in this way. Therefore, the depth and length can be adjusted according to the embedding depth of the wiring equipment box. Since a notch is provided at the end of the cutting line, the cutting line can be cut without using a tool. If notches are provided at both ends or at the through-hole portion, cutting becomes even easier.

By the way, in order to mount the insulating separator 3' shown in FIG. 1, it is necessary to have a wiring equipment box 1' provided with ribs 11 as shown in the same figure. Standard wiring equipment box 1 as shown in Figure 3
could not be used. This is because such a wiring equipment box does not have ribs for fixing the insulating separator.

Furthermore, as shown in Fig. 1, when a coating allowance cover 2 is added to the front opening of the wiring equipment box 1', there is a drawback that the insulating separator cannot be attached or removed after installation. Ta. However, in the insulating separator of the above embodiment, the skirt portion 32 has flexibility and is adapted to press against the inner wall surface of the box 1 due to its elasticity, so there is no insulating separator support rib 11 as in the conventional case. It can be mounted evenly and can be moved laterally. Furthermore, the extension dimension of the skirt portion 32 can be changed freely due to its elasticity;
Even if there is a paint allowance cover 2, it can be attached and removed.

FIG. 5 shows an embodiment of an insulating separator with a tear line for mounting on a conventional power distribution equipment box 1' with an insulating separator support lip. In this case as well, the depth and length can be adjusted by cutting at the tear line 33. Even if the wiring equipment box is buried too deeply into the wall surface in the usage state without using the coating allowance cover, the gap between the front plate covered on the front side of the wiring equipment box 1' and the front end surface of the insulating separator 3b There is no gap between the wires and the wiring devices for low electric current and those for heavy electric current can be completely separated. In the figure, 31 is a main body, 34 is a V-shaped notch, and 36 is a through hole having a notch 35. In the above two embodiments, two through holes 36 are provided for each cutting line, but 1 It doesn't matter if it's one by one. The cutoff line may be of a form in which a large number of small holes are provided in a straight line instead of the grooves, as long as the insulating separator is not bent. In this case as well, it is necessary to provide a notch only at the end of the perforation line. In the embodiment shown in FIG. 4, the main body portion and the skirt portion are separate parts and are connected by fitting, but they may be integrally molded.

C Effects of the Invention As described above, the insulating separator of the present invention is provided with an appropriate number of cut lines and notches on the front side of the plate-like main body for adjusting the depth and length. Because of its construction, it can be adjusted to accommodate slight variations in the depth of standard wiring equipment boxes, and can be easily torn apart by hand without the need for tools.
