Description

Technical Field

[0001] The present invention relates to a wiring box device and a partition member in which a partition member is attached inside a wiring box installed on the back side of a building wall material.

Background Art

[0002] When installing a wiring box on the back side of a building wall material, a wall hole is provided in the wall material so that the opening of the wiring box faces the wall surface. The wall hole can be formed, for example, as described in Patent Document 1, by simply providing a plurality of circular holes such that a part of each hole overlaps with the others. In addition to the method of forming a circular hole, the wall hole can also be formed by moving a coping saw along the periphery of the opening of the wiring box.

[0003] On the other hand, a partition member may be attached to the wiring box to partition the internal space. The partition member can be attached, for example, by providing partition plate insertion ridges for attaching the partition member on the inner surface of the peripheral wall of the wiring box and inserting the end portion of the partition member between a pair of partition plate insertion ridges.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when forming a wall hole using a coping saw, the coping saw is moved back and forth in the depth direction of the wiring box along the periphery of the opening of the wiring box to cut the wall material. However, there is a case where the coping saw interferes with the attachment portion formed by the partition plate insertion ridges provided on the inner surface of the peripheral wall of the wiring box, and the cutting operation cannot be performed smoothly.

[0006] Therefore, the object of the present invention is to provide a wiring box device and a partition member that prevent interference between the reciprocating saw and the attachment portion of the wiring box to which the partition member is attached when creating an opening in the wiring box. [Means for solving the problem]

[0007] The wiring box device according to claim 1 comprises a wiring box having a peripheral wall with an annular side wall and an opening formed at least at one end that allows communication between the inside and outside, The partition member comprises a plate-shaped main body and an attachment portion for attaching the main body, which is inserted through the opening, to an attachment portion provided on the wiring box such that it is positioned to divide the internal space surrounded by the peripheral wall. The partition member inserted through the opening can be attached in a state in which movement in the opposite direction to the insertion direction is restricted by moving the entire member in a direction different from the insertion direction.

[0008] As a result, the partition member inserted through the opening can be attached to the attachment point by moving it in a direction different from the insertion direction, thus allowing the attachment point to be formed with a through hole or the like. Therefore, it is possible to ensure that the attachment point does not protrude inward from the opening of the wiring box, and when moving a coping saw along the periphery of the opening of the wiring box installed behind the wall to form a wall hole in the wall material, interference between the coping saw and the attachment point can be avoided.

[0009] Furthermore, if the wiring box is cantilevered and fixed to a column behind the wall on one side, and the partition member is pushed in from the wall hole in the depth direction of the wiring box, which is deep inside the wall, there is a risk that excessive load will be applied to the fixing point of the wiring box to the column due to the pushing, which may damage the fixing point. However, in the wiring box device of claim 1, the partition member is attached to the attachment point by moving it in a direction different from the insertion direction, and since it is not attached by pushing it deep inside the wall, no load is applied to the fixing point of the wiring box to the column.

[0010] The wiring box device according to claim 2 is characterized in that the peripheral wall has a bottom wall on the other end side opposite the opening, the attachment portion is provided on the bottom wall, and the partition member can be attached to the attachment portion by moving it relative to the bottom wall in a direction along its surface direction. As a result, the part to be attached is located on the bottom wall, and therefore does not interfere with the reciprocating saw that moves along the opening.

[0011] The wiring box device according to claim 3 is characterized in that, in particular, at least a portion of the inner circumferential surface of the side wall is located outside the inner circumferential surface of the opening, and the attachment portion is provided at the location on the outer side of the side wall and does not protrude inward beyond the opening. This prevents interference between the reciprocating saw, which moves along the opening, and the part being attached.

[0012] The wiring box device according to claim 4 is particularly characterized in that the attachment portion consists of a through hole penetrating the peripheral wall. The attachment portion consists of an insertion portion that is inserted into the through hole and a clamping portion that clamps the periphery of the through hole in the peripheral wall from both sides. As a result, the attachment point has a simple configuration of a through-hole, and there are no parts that protrude inside or outside the peripheral wall, so the attachment point does not get in the way when the partition member is not in use.

[0013] The partition member according to claim 5 is attached to a wiring box that has a bottomed box shape with an opening and a through hole formed in the bottom wall, and divides the internal space of the wiring box, The device comprises a plate-shaped main body and an attachment portion having an insertion portion that is inserted into the through hole and a clamping portion that clamps the periphery of the through hole in the bottom wall from both sides, and is positioned such that when attached, the main body divides the internal space.

[0014] The partition member according to claim 6 is particularly capable of gripping the bottom wall by rotating the entire structure around the insertion portion as an axis. [Effects of the Invention]

[0015] In this invention, the partition member inserted through the opening can be attached to the attachment point by moving it in a direction different from the insertion direction. This allows the attachment point to be formed as a through hole or the like, preventing the attachment point from protruding inside the opening of the wiring box. Therefore, when moving a coping saw along the periphery of the opening of the wiring box to form a wall hole in the wall material, interference between the coping saw and the attachment point can be prevented, allowing for the smooth formation of the wall hole.

[0016] Furthermore, the mounting portion of the wiring box can be formed with a through-hole that penetrates the peripheral wall. The end of the mounting portion of the partition member can then be inserted into the through-hole, and the entire partition member can be moved in a direction different from the insertion direction, along the peripheral wall surface, to clamp the peripheral wall in the thickness direction. In this case, the mounting portion does not require any special configuration and simply needs to have a through-hole. In addition, since there are no protrusions on the peripheral wall of the wiring box for attaching the partition plate, the mounting portion does not get in the way when the partition member is not in use.

[0017] Furthermore, when the wiring box is cantilevered and fixed to a stud behind the wall on one side, the partition member is attached to the mounting point by moving along the surrounding wall surface in a direction different from the insertion direction. Since the attachment is not done by pushing the wiring box in the depth direction, no load is placed on the fixing point of the wiring box to the stud, and a stable fixed state can be maintained.

Embodiments for Carrying out the Invention

[0019] Hereinafter, the wiring box device and the partition member of the embodiment of the present invention will be described based on the drawings. The wiring box device 1 consists of a wiring box 10 having a peripheral wall 11 with an annular side wall 12 and an opening 14 formed at one end to connect the inside and outside, and a partition member 30 having a plate-shaped main body and an attachment part for attaching the main body inserted through the opening 14 to an attachment part provided on the wiring box 10. The partition member 30, which is inserted through the opening 14 by passing through the wall hole 51, can be attached in a state in which movement in the opposite direction to the insertion direction is restricted by moving it in a direction different from the insertion direction. Here, the partition member 30 partitions between multiple wiring devices housed in the wiring box 10 and between different cables such as low-voltage and high-voltage cables connected to them. The individual components will be described below.

[0020] <First Embodiment> First, Figures 1 to 8 show the wiring box device 1A of the first embodiment. In Figures 2 and 3, the wiring box 10 is a horizontally elongated box with a bottom, having an opening 14 at one end that connects the inside and outside, and is made of synthetic resin or the like. The peripheral wall 11 has a side wall 12 that forms an annular shape of a rectangular frame plate and forms the opening 14, and a bottom wall 13 is provided at the other end opposite the opening 14, and the peripheral wall 11 forms the internal space 15. The side wall 12 consists of a pair of side walls 12a, 12a that form the opposing short sides of the rectangle, and a pair of side walls 12b, 12b that form the opposing long sides of the rectangle. The wiring box 10 is installed on the back side of the building wall, and the entire internal space 15 is visible to the front side of the wall material 50 through a wall hole 51 formed through the wall material 50 of the building, and wiring devices, cables, etc. are housed in the internal space 15.

[0021] The wiring box 10 has a pair of bosses 16, 16 extending from the bottom wall 13 to the inner surfaces of the pair of side walls 12a, 12a on the short side, facing the opening 14. Screws 64 are attached to the bosses 16 in mounting holes 63 on both sides of the wiring device mounting frame 62 equipped with wiring devices 61, thereby allowing the wiring device mounting frame 62 to be attached from the front side of the opening 14. The tip of the boss 16 on the opening 14 side is positioned at a predetermined distance set back toward the bottom wall 13.

[0022] The bottom wall 13 has a roughly oval-shaped through-hole 22 in the center that penetrates the peripheral wall 11. The through-hole 22 is the attachment part 21 to which the attachment part 32 of the partition member 30 is attached. Here, if a detectable part 18 is provided in the through-hole 22 for detecting the position of the opening 14 of the wiring box 10 on the back side of the wall from the front side of the wall before forming the wall hole 51 after the wall material 50 is erected, it becomes possible to make the opening 14 of the wiring box 10 face the front of the wall even if it is covered by the wall material 50. In this embodiment, as shown in Figure 2, an example is shown in which the detectable part 18 is provided in the through-hole 22 via folded-off parts 17 provided at two locations on its periphery. The detectable part 18 is formed in a cylindrical shape and has a magnet embedded inside, and the position of the magnet on the back of the wall is detected from the front of the wall by magnetic force. The detection portion 18 is removed by breaking off the break-off portion 17, and after removal, a through hole 22 is formed in this portion, as shown in Figure 3.

[0023] The through-hole 22 may be formed from the beginning. In this case, the detection area 18 may be formed in a location other than the through-hole 22 in the bottom wall 13, or it is not necessary to provide it if the position of the opening 14 can be indicated by dimensional measurement or other means without using the detection area 18 when forming the wall hole 51 with a coping saw. Cable entry holes 19, formed by punching, are provided on both sides of the through-hole 22 in the bottom wall 13. The bottom wall 13 is also provided with two fixing holes 20 for use when fixing the bottom wall 13 to the wall material 50.

[0024] The pair of side walls 12a, 12a on the shorter side are provided with fixing parts 23 for their outer surfaces to abut against the building's column 52 and secure with screws 53. The fixing parts 23 are formed by two vertically extending, elongated holes in the side wall 12a on the shorter side, in a direction perpendicular to the bottom wall 13. The wiring box 10 may also be fixed to the column 52, etc., using a separate fixing member.

[0025] Next, as shown in Figure 4, the partition member 30 comprises a plate-shaped main body 31 and an attachment part 32 that attaches the main body 31, which is the attachment part 21 of the wiring box 10, to the through hole 22 so that the main body 31 inserted through the opening 14 is positioned to divide the internal space 15. The main body 31 is formed in a rectangular plate shape, and two V-shaped folding grooves 33 are formed at intervals in the length direction, i.e., the horizontal direction in Figure 4(c), with the grooves 33 spaced apart, and extending linearly in the width direction. The main body 31 can be divided according to the volume of the internal space 15 of the wiring box 10 and the thickness of the wall hole 51 by folding along the folding grooves 33, and can be changed to three different horizontal lengths.

[0026] The attachment portion 32 is connected to one end of the main body portion 31 in the longitudinal direction, perpendicular to the plane of the main body portion 31, and consists of an insertion portion 34 made of a roughly oval-shaped plate material that is inserted into the through hole 22, and a rectangular plate-shaped clamping portion 35 provided parallel to the main body portion 31 at a predetermined distance from the insertion portion 34. The insertion portion 34 and the clamping portion 35 are connected by two connecting portions 36 provided at the upper and lower parts between them.

[0027] The insertion portion 34 is formed to be approximately the same shape as the through hole 22 but slightly smaller, and the outer shape of the clamping portion 35 is formed to be slightly larger than the through hole 22. As shown in Figure 4(b), the connecting portion 36 has one end in the longitudinal direction formed in an arc shape and the other end formed in a straight line. The distance between the insertion portion 34 and the clamping portion 35 is formed to be slightly smaller than the thickness of the bottom wall 13 of the wiring box 10. The attachment portion 32 is attached to the through hole 22 by having the periphery 22a of the through hole 22 in the bottom wall 13 fit into the space at the upper and lower ends of the insertion portion 34 and the clamping portion 35, and by clamping the periphery 22a from both sides.

[0028] The partition member 30 is inserted into the wall hole 51 from the front side by gripping the end of the main body 31, and after inserting the insertion part 34 into the through hole 22, the attachment part 32 is attached to the through hole 22 by rotating it 90 degrees in a direction along the surface direction of the bottom wall 13 relative to the through hole 22, thereby restricting movement in the opposite direction of insertion and preventing it from coming loose. To facilitate the work of inserting and attaching the partition member 30 into the opening 14 of the wiring box 10, it is desirable to set the length in the insertion direction such that when installed, the tip of the main body 31 on the side opposite the attachment part 32 protrudes from the opening 14 of the wiring box 10 to the front side of the wall and fits within the thickness of the wall hole 51. In addition, the surface of the attachment part 32 on the side opposite the main body 31 is formed as a flat adhesive surface 37 to which double-sided tape can be attached. This makes it possible to attach the partition member 30 to any location on the flat surface of the wiring box 10.

[0029] Next, a method for installing the partition member 30 of the wiring box device 1 into the internal space 15 of the wiring box 10 will be described. First, insert the screws 53 through the elongated holes in the fixing part 23 so that the opening 14 faces the back surface of the wall material 50, and attach the wiring box 10 to the side of the column 52 as shown in Figure 5. At this time, fix the side wall 12 so that the tip surface is flush with the front surface of the column 52. Next, erect the wall material 50 so that it abuts the tip surface of the side wall 12 of the wiring box 10 and the front surface of the column 52. Once the wall material 50 is erected, the opening 14 of the wiring box 10 is covered by the wall material 50, so use a magnetic detector to detect the position of the magnet embedded in the detectable part 18 inside the wiring box 10 from the surface of the wall, and use that position as a reference to determine the periphery 14a of the opening 14 of the wiring box 10 and mark the outline on the surface of the wall material 50.

[0030] Next, a coping saw is used to cut the wall material 50 along the outline of the opening 14 shown on the wall material 50, forming a wall hole 51, which allows the internal space 15 of the wiring box 10 to be seen from the wall hole 51 to the wall surface. At this time, the attachment portion 21 of the wiring box 10 to which the partition member 30 is attached is provided in the bottom wall 13 and consists of a through hole 22, so it does not protrude into the internal space 15 and does not interfere with the coping saw, allowing the wall material 50 to be cut smoothly and the wall hole 51 to be formed.

[0031] Once the wall opening 51 is formed, as shown in Figure 6(a), the partition member 30 is laid on its side and inserted through the wall opening 51 from the front of the wall into the internal space 15 facing the front of the wall from the opening 14 of the wiring box 10. Then, as shown in Figure 6(b), the insertion tip 34 is inserted into the through hole 22 in the bottom wall 13 of the wiring box 10. At this point, when the insertion tip 34 is inserted, the end of the main body 31 of the partition member 30 on the side opposite the attachment portion 32 protrudes beyond the opening 14 of the wiring box 10 to about halfway through the thickness of the wall opening 51. This makes it easy to pinch and manipulate the partition member 30 when inserting and attaching it.

[0032] Furthermore, the main body portion 31 of the partition member 30 is adjusted in length by folding off the folding groove 33 as appropriate, either before or after attachment to the wiring box 10, according to the volume of the internal space 15 of the wiring box 10 and the thickness of the wall hole 51. This prevents the end of the main body portion 31 from interfering with the wiring device mounting frame 62 after it has been installed.

[0033] After inserting the insertion portion 34 into the through hole 22, the clamping portion 35, having a larger outer diameter than the through hole 22, does not pass through the through hole 22 but instead contacts the inner surface of its periphery 22a. Subsequently, the main body portion 31 is grasped and the entire partition member 30 is rotated 90 degrees around the insertion axis along the surface direction of the bottom wall 13. As a result, as shown in Figures 1 and 7, the partition member 30 is mounted in a position where the insertion portion 34 and the clamping portion 35 clamp the bottom wall 13 material, and the main body portion 31 divides the internal space 15 of the wiring box 10 into two parts in the middle.

[0034] Here, as shown in Figure 4(b), the connecting portion 36 between the insertion portion 34 and the clamping portion 35 is formed with one end in an arc shape and the other end in a straight line. The arc-shaped portion allows the attachment portion 32 to rotate smoothly, and once it has rotated to 90 degrees, the straight portion prevents it from rotating any further. After attachment, the insertion portion 34 comes into contact with the outer surface of the periphery 22a of the through hole 22, restricting the movement of the partition member 30 in the opposite direction of insertion and preventing it from coming loose from the through hole 22.

[0035] After installing the partition member 30, the cable 60, which has been routed into the wiring box 10 through the cable entry hole 19 behind the wall, is pulled out to the front of the wall and connected to the wiring device 61 held by the wiring device mounting frame 62. Then, the cable 60 is pushed back to the back of the wall, a screw 64 is inserted through the mounting hole 63 of the wiring device mounting frame 62, and the wiring device mounting frame 62 is attached to the boss portion 16 inside the wiring box 10. The state after installation is shown in Figure 8. After that, although not shown in the figure, a decorative plate is attached to the front side of the wiring device mounting frame 62. This completes the installation of the wiring device 61 to the wall material 50.

[0036] <Second Embodiment> Next, the wiring box device 1B of the second embodiment will be described with reference to Figures 9 and 10. Note that the wall material 50 and wall hole 51 are not shown in Figures 9 and 10. The wiring box 10 of the second embodiment differs from the first embodiment mainly in the attachment portion. In the first embodiment, the attachment portion provided on the bottom wall 13 of the wiring box 10 is formed by a through hole 22, but in the second embodiment, it is formed by an L-shaped locking projection 25 erected in the center of the bottom wall 13. Two locking projections 25 are arranged side by side in the width direction at an interval in the middle of the length direction of the bottom wall 13, and a locking piece 25b is formed by bending perpendicularly from the end of the rising piece 25a, and an attachment space 25c is formed between the bottom wall 13 and the locking piece 25b into which the insertion portion 40 of the attachment portion 39 of the partition member 30 fits.

[0037] On the other hand, the partition member 30 of the second embodiment consists of a rectangular plate-shaped main body portion 38 sized to divide the internal space 15 of the wiring box 10 into two, and a U-shaped plate-shaped attachment portion 39 integrally provided on one end of the main body portion 38. Similar to the first embodiment, the main body portion 38 is set to a length such that the end portion on the side opposite the attachment portion 39 fits within the thickness of the wall hole 51 after attachment, or at least to a size that does not interfere with the wiring device mounting frame 62 that is subsequently attached. The attachment portion 39 consists of an elongated rectangular plate-shaped insertion portion 40 and an elongated rectangular plate-shaped clamping portion 41 formed on its opposite side, which are integrally connected by an elongated plate-shaped connecting portion 42. The locking space 43 between the insertion portion 40 and the clamping portion 41 is formed at a distance slightly smaller than the thickness of the bottom wall 13.

[0038] To install the partition member 30 of the wiring box device 1B of the second embodiment inside the wiring box 10, the wall material 50 is cut using a coping saw along the outer shape of the opening 14 of the wiring box 10, which is marked on the wall material 50, in the same manner as in the first embodiment, to form a wall hole 51. The outer shape of the opening 14 of the wiring box 10 on the back of the wall is marked on the wall material 50 in the same manner, for example, by providing a detectable part 18 at an appropriate position on the bottom wall 13.

[0039] Next, as shown in Figure 9(a), the partition member 30 is inserted into the internal space 15 by passing it from the attachment portion 39 side through the wall hole 51 and then through the opening 14 of the wiring box 10. Once the insertion portion 40 reaches the bottom wall 13, as shown in Figure 9(b), the entire partition member 30 is slid along the length of the bottom wall 13 along the surface direction of the bottom wall 13, and while moving relative to the bottom wall 13, the locking piece 25b of the locking projection 25, which is the attachment portion 24 of the wiring box 10, is pushed into the locking space 43 between the insertion portion 40 and the clamping portion 41, and is clamped to attach it. The state after attachment is shown in Figures 9(c) and 10.

[0040] <Third Embodiment> Next, the wiring box device 1C of the third embodiment will be described with reference to Figures 11 and 12. Note that the wall material 50 and wall hole 51 are not shown in Figures 11 and 12. In the third embodiment, the wiring box 10, compared to the wiring box 10 of the first embodiment, has an elongated rectangular through-hole 27 formed in the middle of the length of one side wall 12b on the longer side, to which the insertion portion 46 of the attachment portion 45 of the partition member 30 of the third embodiment is attached. The width of the through-hole 27 is formed to allow the insertion portion 46 of the partition member 30 to be inserted. The peripheral edge 27a on the longer side of the through-hole 27 constitutes the attachment portion 26.

[0041] Furthermore, as shown in Figure 11(b), a canopy portion 28 that protrudes toward the inside of the opening 14 is integrally formed along the entire length of the side wall 12b at each of the ends of the pair of side walls 12b that constitute the long side, and as a result the width of the opening 14 is narrowed slightly inward compared to the opening 14 of the first and second embodiments.

[0042] The partition member 30 of the third embodiment has a shape and form almost the same as the partition member 30 of the second embodiment, and consists of a rectangular plate-shaped main body portion 44 sized to divide the internal space 15 of the wiring box 10 into two, and a U-shaped plate-shaped attachment portion 45 integrally provided on one end of the main body portion 44. The attachment portion 45 consists of an elongated rectangular plate-shaped insertion portion 46 and an elongated rectangular plate-shaped clamping portion 47 formed on its opposite side, which are integrally connected by an elongated plate-shaped connecting portion 48. In addition, in the partition member 30 of the second and third embodiments, an adhesive surface 37 to which double-sided tape can be attached may be formed on the surface of the attachment portion opposite the main body portion.

[0043] To install the partition member 30 of the wiring box device 1C of the third embodiment inside the wiring box 10, a wall hole 51 is formed in the wall material 50 in the same manner as in the first and second embodiments. Then, the partition member 30 is inserted into the wall hole 51 from the front side of the wall. Furthermore, after passing it through the opening 14 of the wiring box 10 and the tip surface reaches the bottom wall 13, the insertion part 46 is passed through the through hole 27. Then, the partition member 30 is slid along the surface direction of the side wall 12, and the insertion part 46 and the clamping part 47 clamp one of the peripheral edges 27a in the width direction of the through hole 27. Figure 12 shows the state after the partition member 30 has been installed.

[0044] Furthermore, since the attachment portion 45 can be attached to either side of the periphery 27a in the width direction of the through hole 27, the volume ratio of the two divided spaces in the internal space 15 of the wiring box 10, which is separated by the partition member 30, can be slightly different depending on which periphery 27a it is attached to.

[0045] Here, as shown in Figure 11(b), the wiring box 10 has a canopy portion 28 that protrudes inward from the tip of the long side wall 12b. Therefore, even if the attachment portion 26 provided on the long side wall 12b is not formed by a through hole 27 but protrudes slightly into the internal space 15 like the locking projection 25 in the second embodiment, if the attachment portion 26 is provided so as not to protrude inward from the virtual side wall surface 12c, which is shown by a dashed line parallel to the side wall 12b with the periphery 14a of the opening 14 being slightly narrower by the amount of the canopy portion 28 as its base, then when forming the wall hole 51 along the outer shape of the opening 14, the coping saw will not interfere with the attachment portion 26, which consists of a locking projection provided on the side wall 12b that is set back outward from the virtual side wall surface 12c.

[0046] Next, the operation of the wiring box device 1 and partition member 30 in each of the above embodiments will be explained. The wiring box device 1 can be attached to the part to be attached by moving the partition member 30, which is inserted through the opening 14, in a direction different from the direction of insertion through the wall hole 51 and the opening 14 of the wiring box 10, that is, along the surface of the peripheral wall 11, in a rotational direction or linear sliding direction perpendicular to the insertion direction, so that the part to be attached can be formed with a through hole or the like. This makes it possible to prevent the part to be attached from protruding inside the opening 14 of the wiring box 10. As a result, interference between the coping saw and the part to be attached can be prevented when forming the opening 14 of the wiring box 10, and the wall hole can be formed smoothly.

[0047] Furthermore, by forming the attachment portion of the wiring box 10 with a through-hole 22 that penetrates the peripheral wall 11, the attachment portion of the partition member 30 can be attached by inserting the insertion portion of the attachment portion into the through-hole 22 and clamping the peripheral wall 11 in the thickness direction. Therefore, no special configuration is required for the attachment portion; it is sufficient to simply have a through-hole 22. In addition, since there are no protrusions in the interior or exterior of the peripheral wall 11 of the wiring box 10 for attaching the partition member 30, the attachment portion does not get in the way when the partition member 30 is not in use.

[0048] Furthermore, when the wiring box 10 is cantilevered and fixed to the column 52 behind the wall on its side, the partition member 30 is attached to the attachment point by moving it in a direction different from the insertion direction toward the back of the wall, and is not attached by pushing the wiring box 10 in the depth direction. Therefore, when the partition member 30 is attached, no load is placed on the part of the wiring box 10 that is fixed to the column 52, and a stable fixed state can be maintained.

[0049] By the way, in order to facilitate the work of inserting and attaching the partition member 30 in each of the above embodiments into the opening 14 of the wiring box 10, the length in the insertion direction is formed such that the end opposite to the insertion side fits into the thickness of the wall hole 51. However, it may be shorter if it does not hinder workability, or it may be longer than the above dimension if it does not interfere with the wiring device mounting frame 62 after it has been installed.

[0050] Furthermore, in the first embodiment, the attachment portion of the partition member 30 has an attachment surface 37 formed on the side opposite the main body portion, which can be attached to any flat surface in the wiring box 10; however, the attachment surface 37 is not necessarily required.

[0051] Furthermore, in the first embodiment, the connecting portion 32 of the partition member 30 is formed in an arc shape on one end in the longitudinal direction and in a straight line on the other side to prevent it from rotating beyond 90 degrees. However, small protrusions may also be provided on the periphery 22a of the through hole 22 in the bottom wall 13 to prevent it from rotating beyond 90 degrees.

[0052] Alternatively, a small hemispherical projection may be provided at another location on the periphery 22a of the through hole 22, so that when the insertion portion 34 rotates up to 90 degrees, it elastically overcomes this projection, preventing the insertion portion 34 from rotating in the reverse direction after it has rotated to 90 degrees. This ensures that the attachment portion 32 is stably held in a fixed position after rotating 90 degrees. These small protrusions, which prevent the device from being reversed after it has been attached, may also be provided in the wiring box device 1 of the second and third embodiments.

[0053] Furthermore, the inner surfaces of the insertion portion and clamping portion of the partition member 30 in each of the above embodiments, as well as the peripheral surface of the portion to be attached on the peripheral wall of the wiring box 30, may be formed as a slightly inclined tapered surface or a rough surface to clamp the portion to be attached and maintain a stable attachment state.

[0054] In the second embodiment, a pair of locking projections 25 are provided in the central part of the bottom wall 13, but they may also be provided in locations other than the central part of the bottom wall 13, or multiple projections may be provided, and the orientation of the locking pieces 25b may be different among multiple projections.

[0055] In the third embodiment, the through-hole 27, which is the attachment portion 26 of the wiring box 10, is provided in the middle of the length direction of one side wall 12b on the long side, but it may also be provided on both side walls 12b on the long side, or it may be provided at a location other than the middle of the length direction. Furthermore, the through-hole 27 may be provided at multiple locations on the side wall 12b, and one of them may be selected when attaching the partition member 30.

[0056] Furthermore, in the wiring box 10 of the third embodiment, a canopy portion 28 is formed over the opening 14 along the entire length of the side wall 12b, and even if the attachment portion 26 protrudes from the surface of the peripheral wall 11 like the locking projection 25 of the second embodiment, it can be prevented from protruding inward from the virtual side wall surface 12c. Alternatively, a canopy portion 28 can be formed by recessing only a part of the side wall 12, and the locking projection 25 of the attachment portion 26 can be provided in the recessed area to prevent it from protruding inward from the opening 14.

[0057] In addition, in the third embodiment, the canopy portion 28 that narrows the opening 14 is integrally formed on the long side walls 12b, 12b on both sides, but it may also be formed on either one of the side walls 12b, provided on the short side wall 12a, or formed on all sides of the side wall 12. Alternatively, the canopy portion 28 may be formed as an opening-forming member attached to the wiring box 10 as a separate component. Furthermore, the wiring box 10 of the third embodiment may not have a canopy portion 28, similar to the wiring box 10 of the first and second embodiments. In this case, it is desirable that the mounting portion of the wiring box 10 be formed by a through hole 27.

[0058] Furthermore, in each of the above embodiments, the insertion tip corner of the partition member 30 is formed at a right angle in the figure, but if it is formed as a tapered surface by chamfering or the like, it will be easier to insert into the part to be attached to the wiring box. Similarly, in the part to be attached to the wiring box 10, the insertion opening corner is formed at a right angle in the figure, but if it is formed as a tapered surface by chamfering or the like, it will be easier to insert the attachment part of the partition member 30.

[0059] Furthermore, although the main body of the partition member 30 in the above embodiment is formed in the shape of a flat plate, it may also be formed in the shape of a curved plate or the like.

[0060] In addition, although the wiring box 10 is formed in a rectangular box shape, it is not limited to this shape. Furthermore, although the wiring box 10 has an opening 14 formed on one axial end of the annular side wall 12, it may also have openings formed on both ends. In this case, since there is no bottom wall 13, the part to be attached is provided on the side wall 12.

[0061] Furthermore, when implementing the present invention, the mounting portion of the wiring box 10 and the partition member 30 are not limited to those described in the above embodiments. The mounting portion may be of other forms as long as the coping saw does not interfere with the mounting portion of the wiring box 10 when forming the wall hole 51 in the wall material 50 along the outer shape of the opening 14 of the wiring box 10 using a coping saw.

[0062] In each of the above embodiments, the wiring box device 1 has one partition member 30 attached, but multiple attachment points may be provided so that one or more partition members can be selected to be attached.

[0063] In addition, the wall hole 51 in the wall material 50 is created by cutting the wall material 50 with a coping saw along the periphery 14a of the opening 14 of the wiring box 10, thereby exposing almost the entire interior space 15 to the wall surface. However, it is also possible to expose only a portion of the interior space 15 to the wall surface. [Explanation of symbols]
