Next, the cable K is inserted into each conduit 33, and each cable K is drawn into the box body 12. At this time, each cable K is wound around each cable K so that the cable K can be pulled out to the front side of the wall member 34 erected on the front side of the box body 12 later. A long portion Y is provided. And the cable K which has the surplus length part Y is accommodated in each accommodation space. At this time, since the accommodation space is formed by the installation spaces S1 to S3, the pair of cables K having the extra length Y are accommodated in the accommodation space with a margin. Moreover, since all the installation spaces S1 to S3 are open, the work of housing the pair of cables K in the housing space of the box body 12 is easily performed.

  Subsequently, the upper and lower wiring device attachment portions 15 at the center of the box body 12 and the upper and lower mounting recesses 23 of the blocking wall 21 are aligned. Further, the mounting groove 16a adjacent to the wiring device attaching portion 15 and the support leg 22 are aligned. Then, when each support leg 22 is inserted into the mounting groove 16a and the end surface of each support leg 22 is brought into contact with the bottom wall 12a which is the bottom surface of the box body 12, as shown in FIG. The blocking wall 21 is supported on the opening side of the box body 12 separated by a length. Further, as shown in FIG. 1, in this contact state, each mounting protrusion 24 engages with the engagement hole 16b of the upper wall 12b and the lower wall 12c, respectively. As a result, the closing wall 21 is supported at a fixed position by the four support legs 22 without moving to the inner side of the box body 12, and the box body is engaged by the engagement relationship between the mounting protrusion 24 and the engagement hole 16b. 12 is attached in a state where the closing member 20 is not easily detached. The blocking wall 21 is located on the same plane as the opening end of the box body 12.

  As shown in FIG. 4, one installation space S <b> 2 located in the center among the three installation spaces S <b> 1 to S <b> 3 is closed by a single blocking wall 21. Therefore, in the opening of the box body 12, the open area is narrowed. In addition, the guide surfaces 26 are provided so as to extend along the boundary between the installation space S1 and the installation space S2 and the boundary between the installation space S3 and the installation space S2. That is, each guide surface 26 is provided so as to extend along a right side edge that is one side edge in the front view of the installation space S1 and a left side edge that is one side edge in the front view of the installation space S3. Both guide surfaces 26 are provided in the box body 12 so as to extend along straight lines that vertically traverse the opening of the box body 12.

  As shown in FIG. 1, a communication opening 29 is located closer to the bottom wall 12a of the box body 12 than the guide surface 26, and the open installation spaces S1 and S3 and the closed installation space S2 communicate with each other. is doing. That is, even when the box body 12 is provided with the blocking wall 21, the opened installation spaces S1 and S3 and the installation space S2 adjacent thereto are not blocked by the blocking member 20, and the installation spaces S1 to S1. An accommodation space for communication with S3 is secured. A wiring box 11 is formed by the box body 12 and the closing member 20.

  Next, as shown in FIG. 5, wall members 34 (only the front wall member 34 is shown) are erected on both front and rear sides of the wiring box 11, and the wiring box 11 is disposed on the back of the wall. At this time, since the blocking wall 21 is located on the same plane as the opening end surface of the box body 12, the opening end surface of the box body 12 abuts on the back surface of the wall member 34, and a gap is formed between the box body 12 and the wall member 34. Is not formed. In order to install the wiring device on the wall material 34 standing on the front side of the wiring box 11, first, the installation space S 1 is opened for wiring device installation at the opening of the box body 12, and the wall material 34 is opened. Open toward the front side.

  In order to make the installation space S1 face the front side of the wall material 34, first, on the front side of the wall material 34, a position corresponding to the installation space S1 is cut by a cutting tool (not shown), and the blade portion of the cutting tool is further moved. It is made to contact | abut to the inner surface of the upper wall 12b which forms installation space S1. And if a cutting tool is moved along the inner surface of the same wall 12b, the wall material 34 will be cut | disconnected along the one side edge in the front view of installation space S1. Similarly, when the cutting tool is moved along the inner surface of the left wall 12d and the inner surface of the lower wall 12c, the wall member 34 is cut along the two side edges in the front view of the installation space S1. Further, when the cutting tool is moved along the guide surface 26, the cutting tool is guided so that the wall member 34 is cut along one side edge in the front view of the installation space S1, and the opening of the box body 12 is opened. The wall member 34 is cut along a straight line that crosses in the vertical direction. As a result, the wall material 34 is cut along the four side edges that are the outline of the installation space S1 when viewed from the front, and a wall hole 34a having the same shape as that of the installation space S1 when viewed from the front is formed in the wall material 34. .

  As a result, only the left installation space S1 of the opening of the box body 12 is opened toward the front side of the wall member 34 by the wall hole 34a, and the other installation spaces S2 and installation space S3 are hidden behind the wall member 34. At the same time, only the installation space S <b> 2 is blocked by the blocking wall 21. Subsequently, the two cables K in the box body 12 are respectively drawn through the wall holes 34 a to the front side of the wall material 34, and a wiring device is connected to each cable K. At this time, since each cable K was accommodated in the accommodation space with the extra length Y, the front end side of each cable K can be sufficiently drawn out to the front side of the wall member 34, and the connection work with the wiring device can be performed. It is done with a margin. And although not shown in figure, a wiring instrument is attached to the box main body 12 using an attachment frame, and is accommodated and installed in the wiring box 11. FIG. Further, the wall hole 34a is covered with a decorative plate (not shown).

  At this time, since the size of the wall hole 34a is the same size as the installation space S1, even if the box body 12 provided with the three installation spaces S1 to S3 is used, only the installation space S1 is provided. A decorative plate that is applied when using is used. That is, the wall hole 34a can be covered without increasing the size of the decorative plate. When removing the blocking member 20 attached to the box main body 12, a finger is inserted into the pair of circular holes 25, and the finger is hooked on the back surface of the blocking wall 21 to move the blocking member 20 away from the box main body 12. Pull to. Then, the engagement between the attachment protrusion 24 and the engagement hole 16 b is released, and the closing member 20 is removed from the box body 12.

According to the above embodiment, the following effects can be obtained.
(1) The wiring box 11 has the accommodation space composed of the three installation spaces S1 to S3, and the installation space S2 is closed by the closing member 20. Therefore, when the wall hole 34a is drilled in the wall member 34 using the opening of the installation space S1, the wall hole having the same shape as the wall hole drilled when using the box body having the installation space S1 as the accommodation space. 34 a can be drilled in the wall material 34. In addition, the communication opening 29 can secure an accommodation space in the box body 12 in which the installation space S1 and the installation space S3 adjacent to the installation space S1 communicate with each other. Therefore, even if the closing member 20 is attached to the box body 12 with the cable K having the extra length Y accommodated in the box body 12, the accommodation space can be maintained without being blocked. Therefore, it is possible to secure an accommodation space behind the wall that allows the pair of cables K having the extra length Y to be accommodated with a margin without enlarging the wall hole 34a. In particular, it is possible to prevent deterioration of the aesthetic appearance of the wall surface without increasing the size of the decorative plate used to cover the wall hole 34a. In addition, the opening of the accommodation space is partially blocked by the blocking wall 21. Therefore, unlike the case where the entire opening of the accommodation space is open, nails or the like driven from the front side of the wall material 34 are less likely to enter the accommodation space. Accordingly, it is possible to make the cable K accommodated in the accommodation space less susceptible to damage by a nail or the like.

  (2) The entire accommodation space consisting of the installation spaces S1 to S3 can be used as the accommodation space for the two cables K. Therefore, unlike the case where the two cables K are accommodated in the state having the extra length Y in the box body provided with only the installation space S1, the work of accommodating each cable K in the box body 12 is easy. Can be done. Furthermore, unlike the case where the cable K is forcibly bent and pushed into a narrow space, the cable K can be accommodated in a gently bent state, so that the possibility of the cable K being disconnected can be eliminated. In particular, by using the wiring box 11 to accommodate the optical cable, it becomes possible to wind the optical cable with a minimum bending radius, and to prevent damage due to the bending of the optical cable and a decrease in the propagation rate. Can do.

  (3) The opening of the box body 12 is closed using a closing member 20 that is separate from the box body 12. Therefore, after the cable K is accommodated in the accommodation space, the opening can be closed by the closing wall 21, compared with the case where the cable K is accommodated in the box body 12 in which the opening of the box body 12 is previously closed. Thus, the operation of accommodating the cable K in the accommodation space can be performed quickly and easily. Further, since the closing member 20 closes the desired installation space S <b> 2, the closing member 20 does not close the entire opening of the box body 12, but can be attached by selecting an attachment position with respect to the box body 12. Therefore, unlike the case where the entire opening of the box main body 12 is closed in advance, the work for opening the desired installation space S1 is not required, and the wiring box 11 can be easily formed.

  (4) Further, the closing member 20 is set to a size capable of closing only one of the three installation spaces S1 to S3 of the box body 12, and the closing member 20 has a mounting position with respect to the box body 12. It is formed to be changeable. Therefore, the attachment position of the closing member 20 can be changed according to the installation position of the wiring device, and the positions of the installation spaces S1 to S3 to be closed can be changed. Therefore, by changing the installation spaces S1 to S3 to be opened, the installation position of the wiring device can be changed even if the wiring box 11 is fixed to the pillar 31.

  (5) With the guide surface 26, the cutting tool can be moved along one side edge of the installation space S1, and the wall hole 34a having the same shape as the installation space S1 can be easily drilled in the wall material 34. .

  (6) When the closing member 20 is attached to the box body 12, the front surface of the closing wall 21 is located on the same plane as the opening end surface of the box body 12, so that the back surface of the wall material 34 and the opening side end surface of the box body 12 No gap is formed between the two. Therefore, the cutting tool can be quickly inserted into the installation space S1, and the drilling operation of the wall hole 34a can be performed quickly. Further, in a state where the wiring box 11 is installed on the back of the wall material 34, it is possible to prevent foreign matter and the like from entering the inside from between the opening side end surface of the box body 12 and the back surface of the wall material 34.

  (7) When the closing member 20 is attached to the box body 12, the support leg 22 comes into contact with the bottom wall 12a, so that the closing wall 21 is supported on the opening side in the box body 12 that is apart from the bottom wall 12a by a certain length. The Therefore, even if an intruder such as a nail penetrates the wall material 34 and comes into contact with the blocking wall 21, the blocking wall 21 is prevented from moving inward in the box body 12. Accordingly, there is no problem that the housing space is blocked by the closing member 20, and the possibility that the cable K is pushed by the closing wall 21 and is damaged or bent can be eliminated.

  (8) The closing member 20 is attached to the box body 12 so as not to be easily detached by engaging the attachment protrusion 24 with the engagement hole 16b and inserting the support leg 22 into the attachment groove 16a. Therefore, it is possible to prevent the displacement of the blocking wall 21 in the box main body 12 and the like, and the open state of the installation spaces S1 and S3 can be maintained. Therefore, when the wall material 34 is cut by the cutting tool, the trouble that the blocking wall 21 moves to change the shape of the wall hole 34a, the installation space S1 becomes narrow, and the installation work of the wiring apparatus becomes difficult. be able to.

  (9) Since the mounting recess 23 is provided in the closing member 20, when the closing member 20 is attached to the box body 12, the opening of the box body 12 is not covered by the closing member 20 without covering the wiring device attachment portion 15. You can face to the side. Therefore, the wiring device attaching part 15 can be used for attaching the wiring device to the box body 12. That is, a member that closes any of the installation spaces S1 to S3 is attached to the box body 12 using the wiring device attachment portion 15, and the wiring device is attached to the box body using the attachment portion provided on the member. 12 need not be attached. Therefore, the wiring device can be attached to the box body 12 without increasing the work of attaching the members to the box body 12.

In addition, you may change the said embodiment as follows.
In the embodiment, the closing member 20 is attached to the box body 12 by engaging the attachment protrusion 24 and the engagement hole 16b and inserting the support leg 22 into the attachment groove 16a. Good. That is, at least one of the attachment groove 16a and the support leg 22 may be omitted, and the closing member 20 may be attached to the box body 12 only by engagement of the attachment protrusion 24 and the engagement hole 16b.
