It was made for the purpose of providing no wiring box.

In order to solve the above-mentioned problems, the invention described in claim 1 is formed in a rectangular parallelepiped shape having a rectangular opening on the front surface, and is disposed on the back of the wall, and a part of the wall material overlaps with the same diameter. substantially the entire front surface by two through holes to be set is a wiring box that face the wall table, a to be detected portion for determining the drilling center of one hole of said two apertures In addition, the opening end surface of one short wall of the box body peripheral wall is provided with a drilling blade at a position corresponding to a trajectory position through which the drilling blade that drills one of the two through holes passes. A recess for avoiding contact is provided at the opening end surfaces of the pair of long walls, and a recess for avoiding contact with the drilling blade is provided at a position corresponding to a trajectory position through which the drilling blade drills the one through hole. Each is provided.

According to a second aspect of the present invention, there is provided a box which is formed in a rectangular parallelepiped shape having a square opening on the front surface, is disposed on the back of the wall , and partially overlaps and is perforated with the same diameter in the wall material. A wiring box in which substantially the entire front face is faced to the wall surface by four through- holes arranged two along each side wall of the main body , and at least one of the four through-holes A perforation that includes a to-be-detected portion for determining the perforation center of each of the four perforations, and each of the opening end surfaces of the side walls of the box body peripheral wall has two perforations partially overlapping among the four perforations. A concave portion for avoiding contact with the drilling blade is provided at a position corresponding to the trajectory position through which the blade passes.

The invention described in claim 3 is characterized in that, in the invention described in claim 1 or claim 2 , a detected portion is provided at the drilling center of the through hole to be drilled.

According to the first aspect of the present invention, since the detected part is provided in the wiring box, the position of the wiring box arranged on the back of the wall can be detected from the wall surface, and the wall material can be detected. The center position of the through hole to be drilled can be determined. Further, contact with the drilling blade can be avoided at a position corresponding to a trajectory position through which the drilling blade for drilling one of the two through holes is formed in one short wall of the opening end surface of the wiring box. Concave portions are provided, and the opening end surfaces of the pair of long walls are respectively provided with concave portions that can avoid contact with the drilling blades at positions corresponding to the trajectory positions through which the drilling blades drill the one through hole pass. Therefore, when the through hole is drilled in the wall material, the drilling blade is not brought into contact with the opening end surface of the wiring box. That is, for example, even when the wiring box is temporarily fixed, the wiring box can be prevented from being displaced at the time of drilling the through-hole, and the drilling blade is in contact with the opening end surface of the wiring box, It is possible to prevent the box itself from being damaged or the wiring box itself from being damaged such as cracks.

Are provided with recesses that can avoid contact with the perforation blades at positions corresponding to the trajectory positions through which the perforation blades that perforate two of the four perforations partially overlap . When the through hole is drilled in the wall material, the drilling blade is not brought into contact with the opening end surface of the wiring box. That is, for example, even when the wiring box is temporarily fixed, the wiring box can be prevented from being displaced at the time of drilling the through-hole, and the drilling blade is in contact with the opening end surface of the wiring box, It is possible to prevent the box itself from being damaged or the wiring box itself from being damaged such as cracks.

  According to the third aspect of the present invention, since the detected portion is provided at the drilling center of the through-hole to be drilled, the drilling blade can be accurately positioned at the drilling center of the through-hole to be drilled. .

  Hereinafter, the present invention will be described in detail with reference to the drawings. 1 is a partially broken perspective view showing a wiring box 1a according to a first embodiment of the present invention, FIG. 2 is a plan view of the wiring box 1a shown in FIG. 1, and FIG. FIG. 4 is a longitudinal sectional view showing a section A, and FIG. 4 is a longitudinal sectional view showing a section BB in FIG.

  In the figure, the wiring box 1a of this embodiment is arranged behind the wall, and the front surface of the wiring box 1a faces the wall surface through a through hole 20 drilled in the wall material W. A pair of bosses for attaching a wiring device mounting frame for housing a wiring device and the like, in which the detected portion 2 that can be detected from the wall surface is integrally formed at the eccentric position of the wiring box body. The bodies 3a and 3a are protrusively provided in proximity to opposing positions on the peripheral wall of the wiring box body. In the opening end face of the wiring box main body, a trajectory range in which the drilling blade attached to the drilling tool 10 may be displaced due to the detection misalignment of the drilling center position of the through hole 20 ( Recesses 4 for avoiding contact with the drilling blade are formed at all positions corresponding to those indicated by broken lines in FIG. That is, the through-hole 20 can be formed in the wall material W without bringing the perforating blade into contact with the opening end surface of the wiring box 1a.

  The to-be-detected portion 2 has a metal foil 2b bonded to the top end of a tubular body 2a projecting from the bottom wall of the wiring box so that the lower end of the tubular body faces each other. The outer surface of the lower end of the cylindrical body perpendicular to the tongue-shaped attachment portion 2c is connected to the periphery of a circular hole provided in the bottom wall of the wiring box via a connecting portion. It consists of a structure that is integrally connected so as to be separable by folding. However, the part to be detected 2 is not limited as long as a member that can be detected from the wall surface is provided. Examples of the member that can be detected include a metal ring and a magnet in addition to the metal foil 2b described above. it can.

  In general, after the through-hole 20 is drilled in the wall material W, if the detected part remains in the box, it interferes with the installation work of the cable and the wiring device and the accommodation space in the box becomes narrow. It is preferable that the protrusion is provided so as to be removable. In short, the to-be-detected part 2 has a function of making it possible to detect its own position from the wall surface and a function of determining the drilling center position of the through-hole 20 drilled in the wall material W. However, it may be reusable, but it may be appropriately discarded after being broken, such as a detected part provided in a conventional wiring box.

  In addition, as a to-be-detected part which can be reused, a screw is integrally formed at the lower end of the cylindrical body 2 except for the tongue-like attachment part 2c formed at the lower end of the to-be-detected part 2 as described above. In addition, the lower end of the detected part is inserted into a hollow projecting body that is provided in the lower end of the cylindrical body 2 by pressing and fitted into the bottom wall of the wiring box so as to be foldable. Examples (not shown) configured as described above can be exemplified. Further, for example, a separate “detected tool” configured to be directly hooked on the boss body 3 a or the upper peripheral wall of the box may be used.

  Next, the operation of the wiring box 1a of this embodiment configured as described above will be described. First, according to the wiring box 1a of the first embodiment, as shown in FIG. 5, the wiring box 1a is provided in the wiring box 1a even if the wiring box 1a is arranged behind the wall and cannot be seen from the wall surface. If the detected position 2 can be easily detected from the wall surface by the detection tool 30 and then the through hole 20 having the position of the detected section 2 as the drilling center position is drilled in the wall material W, The front surface of the wiring box 1a can be reliably faced to the wall surface through the through hole 20 (FIG. 6).

  And when drilling the through-hole 20 with respect to a wall material, all the rotation locus | trajectories corresponding to the rotation locus | trajectory which the piercing blade of the piercing tool 10 may pass among the opening end surfaces of this wiring box 1a main body. Since the concave portion 4 for avoiding contact with the perforating blade is formed at the position, the through hole 20 can be formed in the wall material W without bringing the perforating blade into contact with the opening end surface of the wiring box 1a. Note that the concave portion 4 acts so as to buffer even if the perforation center position of the through hole 20 is slightly deviated, so that it is not necessary to perform a conventional strict perforation center position detection operation. A remarkable effect can be obtained.

  Therefore, for example, the temporarily fixed wiring box is not displaced and the wiring box itself is not damaged due to the contact of the drilling blade with the opening end surface of the wiring box 1a. An excellent effect is obtained that no damage such as cracking occurs in the box itself.

  Further, after the predetermined through-hole 20 is drilled in the wall material, the detected portion 2 is exposed to the wall surface through the through-hole 20 (FIG. 7), so that the mounting portion 2c remains in the state. It can be removed from the bottom wall of the wiring box 1a (FIG. 8), and then a wiring device mounting frame for housing a wiring device or the like (not shown) is attached to the boss bodies 3a and 3a provided in the wiring box 1a. All work is completed. FIG. 8 schematically shows a state in which the through hole 20 is drilled while the perforation center position of the through hole 20 is displaced, and the displacement of the through hole 20 is buffered by the recess 4. It is shown that it is done.

  As described above, the detected part 2 removed from the bottom wall can be detachably attached to a mounted part provided in another wiring box (not shown) different from the wiring bix via the mounting part 2c. , Can be used repeatedly as "detected tool".

  FIG. 8 is a plan view showing a wiring box 1b according to the second embodiment of the present invention. In the drawing, since the front surface of the wiring box 1b of this embodiment arranged on the back of the wall faces the wall surface through the through hole 20 drilled in the wall material W, the eccentricity of the wiring box 1b main body is shown. At the position, four detected portions 2 that can be detected from the wall surface are integrally formed to be foldable, and two pairs of boss bodies 3a and 3b for attaching a wiring device mounting frame that accommodates the wiring device and the like are provided. The wiring box 1b protrudes in the vicinity of the opposing positions on the peripheral wall of the main body. And, when the four through holes 20 are drilled in the wall material W among the opening end face of the wiring box 1b main body, all corresponding to the rotation trajectory through which the rotating drilling blade provided in the drilling tool 10 passes. A recess 4 for avoiding contact with the drilling blade is formed at the position. That is, the through holes 20 can be formed in the wall material W without bringing the perforating blade into contact with the opening end surface of the wiring box 1b.

  Therefore, the wiring box 1b main body of the second embodiment arranged on the back of the wall has substantially the same effect as the wiring box 1a of the first embodiment. That is, the position of the detected portion 2 provided in the wiring box 1b can be easily detected from the wall surface by the detection tool 30, and the drilling center position of each through hole 20 is determined from the detected position of the detected portion 4. In addition, the through hole 20 having the perforation center position as the perforation center can be formed in the wall material W, and the front surface of the wiring box 1b can be surely faced to the wall surface through the through hole 20.

  Further, when the through hole is drilled in the wall material W, the through hole can be drilled in the wall material W without bringing the perforating blade into contact with the opening end surface of the wiring box 1b. After the predetermined through hole 20 is drilled, the detected portion 2 can be removed via the through hole 20, and then the two pairs of boss bodies 3a and 3b provided in the wiring box 1b are connected to the two pairs of boss bodies 3a and 3b. A wiring fixture mounting frame that accommodates a wiring fixture (not shown) can be attached.

Next, FIG. 9 is a plan view showing a wiring box 1c of the third embodiment of the present invention, FIG. 1 0, the existing position of the wiring box 1c of the third embodiment arranged on the wall behind, It is a longitudinal cross-sectional view which shows typically the state which has detected using the detection tool 30 from the wall surface, and has marked the drilling center position of the through-hole with respect to the wall material.

  In the figure, in the wiring box 1c of the present embodiment, a pair of boss bodies 3a for mounting a wiring device mounting frame for housing a wiring device or the like are close to the opposing positions on the peripheral wall of the wiring box 1c main body. The metal foil 2b (detected portion 2) is provided so as to cover the boss body 3a, and the opening end face of the wiring box 1c main body is against the wall material W. Concave portions 4 for avoiding contact with the drilling blade are formed at all positions corresponding to the trajectory through which the drilling blade passes when the through-hole 20 is drilled, and the drilling blade is brought into contact with the opening end surface of the wiring box 1c. The through-hole 20 can be formed in the wall material W without any problems. Therefore, since it is obvious that the wiring box 1c has substantially the same effect as the wiring boxes 1a and 1b of the first and second embodiments, it will not be described repeatedly.

Next, FIG. 11 is a plan view schematically showing a state after the through holes 20 are formed in the wall material W on the front surface of the wiring box 1d of the fourth embodiment arranged on the back of the wall. is there.

  The wiring box 1d of the present embodiment faces the wall surface through two through holes 20 inscribed in the peripheral wall of the wiring box 1d, and the location of the detected portion 2 detected from the wall surface When the first through-hole 20 ′ having a center of perforation is perforated, even if the perforation center position is slightly displaced, this can be accommodated.

  In the figure, the wiring box 1d of the present embodiment allows the detected portion 2 having the magnet 2d for providing the drilling center position of the first through hole 20 ′ to be folded back to the eccentric position of the wiring box 1d main body. A pair of boss bodies 3a that are integrally formed and for mounting a wiring device mounting frame that accommodates a wiring device or the like are formed at opposing positions on the outer peripheral surface of the peripheral wall of the wiring box 1d; and Of the opening end face of the box body 1d, contact with the drilling blade is made at all positions corresponding to the rotation trajectory through which the drilling blade may pass when the first through hole 20 ′ is drilled into the wall material W. The recessed part 4 for avoiding is formed.

Incidentally, FIG. 1 1 shows a state in which the through holes 20 while drilling center position is misaligned in the through hole 20 is perforated schematically, in a manner similar to that described in FIG. 8, such holes 20 This positional deviation indicates that it is buffered by the recess 4.

  Therefore, the first through-hole 20 ′ can be drilled in the wall material W without bringing the drilling blade into contact with the opening end face of the wiring box 1d, and then the drilling center position of the second through-hole is set to the position of the wiring box. The first through hole 20 ′ is determined so as to be inscribed in the peripheral wall, and a second through hole having this position as a drilling center position is drilled.

  Since it is obvious that the wiring box 1d of the fourth embodiment has substantially the same operational effects as the wiring box of each of the above-described embodiments, it will not be described repeatedly.
