DETAILED DESCRIPTION OF THE INVENTION

<First Embodiment> An embodiment of the present invention will be described below with reference to FIGS. In the figure, a wiring switch box 1 is arranged behind a wall, and its front surface faces a wall surface through a through hole formed in a wall material. The switch box body 2 is detected at an eccentric position from the wall surface. The possible detected part 3 is formed integrally with the bottom wall 4 so that it can be broken off,
A pair of boss bodies 5 for mounting a wiring device mounting frame for accommodating wiring devices and the like are provided so as to project from the bottom wall 4 in the vicinity of opposite positions of the peripheral wall of the switch box body 2.

The detected part 3 is a bottom wall 4 of a wiring box.
A disk-shaped magnet 6 is fitted to the top end of a tubular body 3a that is connected by a thin annular connecting portion 4a and is provided so as to project so that it can be folded. The locking claw 3d of the elastic piece 3c that is inserted from the bottom surface opening 3b and formed on the upper side is elastically spread laterally and is locked on the upper side of the locking claw 3d. The detected portion 3 is connected to the annular connecting portion 4a.
The reason why the switch box can be broken is that if the detected part 3 remains in the switch box body 2 after the through hole is formed in the wall material, it interferes with the work of attaching the cable and the wiring device and the switch box. This is because the accommodating space in the main body 2 becomes narrower so that it can be removed. A magnet accommodating portion 3e is formed below the magnets 6 for accommodating a plurality of additional magnets 6 by inserting the additional magnets 6 from the bottom opening 3b when detecting the switch box body 2. Added magnet 6
Is attracted to the magnet locked by the locking claw 3d, it is not necessary to provide a special locking means in the magnet housing portion 3e. The additional magnet 6 is formed in a disk shape having the same shape and size as the magnet 6 locked by the locking claw 3d, but the shape is not limited to this, and a different shape such as a square disk shape. It doesn't matter.

Next, with respect to the wiring switch box having the above-described structure, the detection of the wiring switch box in the work of punching the wall material will be described. If the wall material has a normal thickness and the switch box for wiring is to be mounted in contact with the back surface of the wall material, that is, for the wiring at the portion where the detected part 3 is close to the magnetic detector. When the switch box 1 is attached, the detected part 3
Can detect the position of the wiring switch box 1 on the back side of the wall and the center position of the perforation with respect to the wall material by using one magnet 6 locked by the locking claw 3d at the top end. .

On the other hand, when the detected portion 3 is separated from the magnetic detector by a predetermined distance or more, that is, when the wall material is thick or the wiring switch box 1 is mounted at a position far away from the wall material. However, since the magnetic force is weak with only the one magnet 6, it may be difficult or impossible to detect.
In such a case, prior to the detection work, an appropriate number of magnets 6 are inserted from the bottom surface opening 3b of the detected part 3 and housed in the magnet housing part 3e. As a result, the magnetic force increases, and the mounting position of the wiring switch box 1 and the center of perforation of the wall material can be detected.

Here, when the magnet 6 is, for example, a disk-shaped ferrite magnet having an outer diameter of 1 cm and a thickness of 3 mm, one magnet has about 500 gauss on the surface portion, but two magnets are laminated. Approximately 680 gauss, three layers are approximately 78
A magnetic force of 0 Gauss was obtained.

After the predetermined through holes are formed in the wall material,
Since the detected part 3 is exposed to the wall surface through the through hole, it is removed from the bottom wall 4 of the wiring switch box 1 through the through hole, and then the boss body 5 provided in the wiring switch box 1 is removed. All the work is completed by attaching a wiring device mounting frame that accommodates wiring devices (not shown).

Next, in the above embodiment, the detected portion 3 is provided so as to project at the eccentric position of the bottom wall 4 of the switch box body 2. However, as shown in FIGS. It is also possible to provide a pair of detected parts 3 on the outer surface of the. In this embodiment, the approximate position of the wiring switch box 1 can be detected from the wall surface by the pair of detected parts 3 on both sides, and when the wall material is thick or at a position distant from the wall material to the inner side, the wiring switch box 1 is detected. In the case of mounting, the position of the wiring switch box 1 can be easily detected by adding the magnet 6 appropriately, similarly to the case where the detected portion 3 is provided at the eccentric position of the bottom wall 4 described above. In addition, in the case of this embodiment, since the detected part 3 is provided outside the switch box body, after the wall material is perforated, the detected part 3 is formed.
Need not be removed.

As described above, the wiring switch box according to the present embodiment has a wiring switch box 1 arranged behind the wall so that the front surface is exposed to the front surface of the wall by the through hole formed in the wall material.
In addition, there is provided a detected portion 3 for providing the approximate position of the wiring switch box 1 or the center position of the perforation on the wall surface by magnetic detection, and the detected portion 3 is laminated with a plurality of magnets 6. It can be accommodated.

Therefore, since the magnetic force in the detected portion 3 can be easily and arbitrarily increased and changed, the wall material is thick,
Even when the wiring switch box 1 is mounted at a position away from the magnetic detector, such as at a position far away from the wall material, the approximate position of the switch box main body 2 or the center of perforation of the wall material The position can be reliably detected.

<Second Embodiment> Next, an embodiment of the present invention will be described with reference to FIGS. In the first embodiment, the detected part 3 is provided integrally with the switch box main body 2, whereas in the second embodiment, the detected part is a separate detection part from the switch box main body 2. A member that can be detachably attached is shown as a member.

First, in FIGS. 6 and 7, a screw hole 4b is provided at an eccentric position of the bottom wall 4 of the wiring switch box 1, and the detected member 8 is inserted into the screw hole 4b.
Can be attached and removed freely. The detected member 8 is not limited to being screwed to the bottom wall 4 of the wiring switch box 1, but may be simply fitted into the hole in the bottom wall. A disk-shaped magnet 6 is fitted to the top end of a tubular body 8a of the detected member 8, and the magnet 6 is formed at an upper portion by being inserted from a side opening 8b formed on a side surface of the tubular body 8a. The locked claw 8c is elastically pushed out to the side and locked on the upper part of the locking claw 8c. Further, below the magnets 6, there is formed a magnet accommodating portion 8d for accommodating a plurality of additional magnets 6 by inserting the additional magnets 6 from the side surface opening 8b during the detection work of the switch box body 2. The lower end surface of the tubular body 8a is integrally formed with a flange portion 8e that comes into contact with the surface of the bottom wall 4 of the switch box body 2 and a screw portion 8f that is screwed into the screw hole 4b.

The detected member 8 of the second embodiment is composed of the magnet 6
Therefore, as in the first embodiment, the wall material is thick, and the wiring switch box 1 is mounted at a position away from the wall material such that the wiring switch box 1 is mounted at a position far from the magnetic detector. Even in such a case, the approximate position of the switch box body 2 or the center position of perforation of the wall material can be reliably detected.

Next, another detected member is shown in FIGS. 8 and 9. In the figure, the detected member 9 is configured such that a plurality of magnets 6 can be inserted and accommodated in the tubular body 9a through the bottom opening 9b, and a wiring switch box is provided on the upper side surface of the tubular body 9a. An attachment portion 9c that is held by gripping the first boss body 5 is integrally provided. The mounting portion 9c of the detected member 9 elastically expands to expand the boss body 5
And a connecting plate 9e for separating the boss 5 from the boss 5 by a predetermined length.

In this embodiment, the detected member 9 is elastically held by the gripping piece 9d, so that the same state as in FIG. 1 can be obtained, and the same action and effect can be expected. In particular, in the present embodiment, the detected member 9 is detachably attached to the boss body 5 of the wiring switch box 1, so that after detecting the wiring switch box 1 and punching it in the wall material, It can be removed and reused again for mounting another wiring switch box 1.

In this embodiment also, the detected member 9
Similarly to the detected member 8 of FIG. 6, a side opening 9f may be formed in the cylindrical body 9a so that the magnet 6 can be inserted from the side, as shown in FIG.

Next, another member to be detected is shown in FIGS. The detected member 10 has a pair of flexible plate-shaped mounting pieces 10b integrally projecting from the side surface of a tubular body 10a. The mounting pieces 10b are opposite side walls of the wiring switch box 1. 7 can be inserted into the insertion groove 7a. That is, a plurality of magnets 6 are added to the detected member 11 of the conventional example shown in FIG. 14 from the bottom opening or the side opening of the cylindrical body 10a so that the magnetic force can be enhanced.

Therefore, in this embodiment as well, the detected member 10 can reliably detect the position of the wiring switch box 1 and the center of perforation of the wall material from the wall surface, and after the perforation of the wall material is made flexible. By bending the mounting piece 10b having the sideways from the insertion groove 7a to the detected member 1
0 can be removed.

In each of the above embodiments, the magnet 6 is added to the inside of the detected portion or the detected member in order to enhance the magnetic force. However, conversely, the wall thickness and the switch box 1 for wiring are shown. If a large magnetic force is not required due to the relationship with the arrangement position of the above, the excess magnet 6 can be removed from the state in which a large number of magnets 6 are accommodated in advance. in this case,
The removed magnet 6 can be diverted to another wiring switch box, and the magnet 6 can be saved.

Further, in each of the above-mentioned embodiments, when the magnet 6 is inserted from the bottom opening or the side opening of the detected part or the detected member, the supplementary magnet 6 is attracted and held by the magnet locked at the top end. However, in order to prevent the supplementary magnet 6 from falling off the bottom opening or the side opening due to an impact from the outside, etc., a seal or the like is attached to the bottom opening or the side opening after the supplementary magnet 6 is housed inside. It may be worn and sealed.

Further, in each of the above embodiments, the detected part,
The magnet 6 is housed and held in the detected member by using the locking claw 3d or the like, or the magnet 6 at the top end is attracted and held.
The present invention is not limited to these means when implementing the present invention.
