Moreover, the cable 61 is illustrated as a wiring material described in this embodiment. Here, the wiring fixture mounting frame 62 to which switches, outlets, and the like are attached is also included in the wiring fixture. Hereinafter, each component will be described in detail.

  The wiring box 11 constituting the wiring fixture mounting body has a bottom wall 12 and a peripheral wall 13 standing from the bottom wall 12, and is formed in a bottomed box shape that opens facing the bottom wall 12. The wiring box 11 is used on the back side of the partition wall through a mounting bracket fixed to the partition column, or is used by being embedded in concrete. The bolt hole 14 provided in the center of the bottom wall 12 is used for attaching a bolt to a formwork when concrete is placed, but is not necessary when the wiring box 11 is disposed on the partition wall. The bottom wall 12 and the peripheral wall 13 are provided with knockouts 15 that are punched to insert the cable 61 as necessary. Further, a pair of mounting flanges 17 for mounting the wiring fixture mounting frame 62 on the front surface of the opening 16 are provided on the periphery 16 a of the opening 16 of the wiring box 11 in the vertical direction, and a screw hole 18 is provided at the center of each mounting flange 17. Is provided. The wiring box 11 is formed of a synthetic resin material or a metal plate.

  Further, the box cover 21 constituting the wiring fixture mounting body is formed in a square frame shape, and the central portion bulges in a trapezoidal shape on one side at a constant height, and almost the entire bulged trapezoidal portion is opened. The opening 22 is formed. A part of the opening 16 of the wiring box 11 is exposed from the opening 22. The opening 22 is formed in a substantially oval shape, and the periphery thereof is formed in a straight line in which the upper and lower portions are curved outward in an arc shape and the left and right side portions are parallel. Arc-shaped long holes 23 are formed in the circumferential direction at positions corresponding to the screw holes 18 of the wiring box 11 at the four corners of the flat portion around the outside of the opening 22 of the box cover 21, and one end of the long hole 23. Is formed in an insertion hole through which the screw 51 can be inserted. Further, as shown in FIG. 2 and FIG. 3 and the like, a pair of mounting flanges 24 projecting in the opening plane direction are opposed to each other at the center portion of the upper and lower peripheral edges of the opening 22. A screw hole 25 into which the screw 51 is screwed is provided in the center of the screw. The attachment flange 24 constitutes an instrument mounting part, and the screw hole 25 constitutes a threaded part into which a screw 51 for attaching a wiring instrument is screwed. The box cover 21 is formed of a synthetic resin material or a metal plate.

  Next, as shown in FIG. 5, the regulation body 31, which is a feature of the present invention, is formed of a synthetic resin in a generally T-shape when viewed from the front, the vertical portion is cylindrical, and the screw 51 is formed inside. A screw insertion space 34a through which the shaft portion is inserted is formed. The restricting body 31 includes an attaching portion 32 attached to the box cover 21, a restricting portion 33 that restricts screwing of the screw 51 to secure the wiring space 19 of the cable 61 in the wiring box 11, and a box cover. And a sliding contact prevention portion 34 that is disposed ahead of the screw 51 in the screwing direction of the screw 21 and that prevents the cable 61 from entering the screwing planned space 20 of the screw 51. ing. Here, with respect to the regulating body 31, the front means a surface that can be seen from the inside of the opening 22 of the box cover 21. Further, the screwing direction of the screw 51 is an arrow direction of the screw 51, as shown in FIG. 7, and the screwing direction described later is the opposite direction.

  First, the attachment portion 32 of the restricting body 31 is a portion attached to the attachment flange 24 which is an instrument attachment portion of the box cover 21, and is formed in a T-shaped horizontal portion, and in the horizontal direction. It is formed by two upper and lower contact portions of an extending front side contact portion 35 and back side contact portion 36. The front-side contact portion 35 is located on the outer surface side of the attachment flange 24 of the box cover 21 when the restricting body 31 is attached to the box cover 21, and the back-side contact portion 36 is located on the inner surface side of the attachment flange 24. In addition, the front-side contact portion 35 and the back-side contact portion 36 are provided as a pair on the left and right sides with a gap 37 at the center. A central gap 37 between the pair of left and right contact portions is a space through which the shaft portion of the screw 51 passes vertically. A groove portion 38 formed between the upper and lower surfaces of the front-side contact portion 35 and the back-side contact portion 36 is a space into which the attachment flange 24 of the instrument mounting portion of the box cover 21 is press-fitted, and the front-side contact portion The attachment flange 24 is sandwiched between 35 and the back side contact portion 36. In addition, in order to further increase the clamping force with respect to the attachment flange 24, both contact parts may be integrally provided with a small projection such as a hemisphere that is elastically pressed against the contact surface.

  Further, the front-side contact portion 35 of the attachment portion 32 is a surface of the attachment flange 24 of the box cover 21 on the screwing direction side of the screw 51, that is, on the upper side of the attachment flange 24 in FIGS. 3 (a) and 3 (b). It has the contact surface 35a which contact | abuts the surface. The front contact portion 36 has a contact surface 36a that contacts the surface of the mounting flange 24 on the screw 51 screwing direction side, that is, the lower back surface of the mounting flange 24 in FIG.

  Among these, as shown in FIG. 6A, the front-side contact portion 35 is an imaginary line 26 indicated by a two-dot chain line extending the end edge 22 a of the opening 22 of the box cover 21, that is, the base end of the attachment flange 24. It is formed so as not to protrude outside the line drawn along the arc as it is across the part. If a part of the front side abutting portion 35 protrudes outside the virtual line 26 as shown by the hatched portion in FIG. 6B, the wall hole into which the opening 22 of the box cover 21 fits is brought into the front side abutting. This is because the portion 35 has to be increased by the amount of protrusion, which may cause a problem described later.

  The mounting portion 32 formed in this way faces the screw 51 from the front side of the box cover 21 because the screw hole 25 of the box cover 21 faces the front side through the gap 37 in the front side contact portion 35 and the back side contact portion 36. It can be inserted into the screw hole 25 and screwed. The screw 51 may be a tapping screw that is forcibly screwed into the screw hole 25 or a screw that is attached using a nut.

  Further, as shown by the arrow in FIG. 3A, the attachment portion 32 is attached to the instrument attachment portion of the box cover 21 from the direction orthogonal to the screwing shaft of the screw 51. In 3 (a), the attachment flange 24 is fitted into the groove portion 38 of the attachment portion 32 from the horizontal direction and is sandwiched between the front-side contact portion 35 and the back-side contact portion 36 to be attached to the box cover 21.

  On the other hand, the restricting portion 33 of the restricting body 31 is provided at the tip of a T-shaped cylindrical vertical portion, and the tip of the screw insertion space 34a is closed by a bottom 39 having a flat bottom surface. . As a result, the tip of the screw 51 that has screwed into the wiring box 11 beyond the screwed portion of the box cover 21 abuts against the bottom surface of the restricting portion 33 and is restricted from screwing further. Note that the bottom surface of the bottom portion 39 does not have to be planar, and may be formed in a recessed surface or the like. The restricting portion 33 is set at a distance away from the attachment portion 32 so that a gap in which the cable 61 can be routed, that is, the wiring space 19 is provided between the tip portion and the bottom wall 12 of the wiring box 11. . The bottom 39 at the tip of the restricting portion 33 has a hemispherical outer surface, and the cable 61 in the wiring box 11 is prevented from being damaged by contact.

Next, the sliding contact preventing portion 34 of the restricting body 31 is formed in a connecting portion 40 that connects the attachment portion 32 and the restricting portion 33, and the screw 51 screwed into the screwing portion of the box cover 21. It is arranged ahead. The sliding contact prevention portion 34 is formed in a cylindrical shape surrounding the shaft portion of the screw 51 screwed into the connecting portion 40, and thereby, a planned screwing space that is the tip of the screw 51 in the connecting portion 40 in the screwing direction. The cable 61 is prevented from entering the inside 20 and slidingly contacting and rubbing against the shaft portion of the screw 51 to be damaged. A meat stealing space is formed on the side surface of the cylindrical connecting portion 40 from the point of resin molding.
The restriction part 33 and the sliding contact prevention part 34 of the restriction body 31 thus formed constitute an interference prevention body that prevents the cable 61 from being damaged by preventing interference with the cable 61.

Next, the attachment of the wiring device to the wiring device mounting body configured as described above will be described.
In advance, the box cover 21 is brought into contact with the opening side of the wiring box 11, and a screw 51 is inserted into the long hole 23 of the box cover 21 and screwed into the screw hole 25 of the mounting flange 17. 21 is assembled together. Therefore, although not shown, the wiring box 11 is fixed to a mounting bracket fixed to the partitioning pillar of the building, the partitioning wall 71 is erected, and the wiring box 11 and the box cover 21 are disposed behind the wall.

  Next, the cable 61 wired on the back of the wall is drawn into the wiring box 11 from the through hole in which the knockout 15 of the wiring box 11 is punched, and is assembled to the wiring fixture mounting frame 62 on the front side of the wall through the wall hole 72 of the partition wall 71. Connect to the terminal of the switch 63. Then, the restricting body 31 is attached to the instrument mounting portion of the box cover 21. At this time, the attachment portion 32 of the restricting body 31 has a front-side contact portion 35 and a back-side contact portion 36 that come into contact with the front side surface and the back side surface of the attachment flange 24 of the box cover 21, respectively. The restriction body 31 can be easily attached to the wiring fixture attachment body by pushing in and fitting the attachment flange 24 into the groove portion 38 of the restriction portion 33. Next, as shown in FIG. 7, the screws 51 are inserted into a pair of insertion holes provided in the upper and lower ends of the wiring fixture mounting frame 62 from the wall surface side, and the pair of upper and lower attachment flanges 24, 24 of the box cover 21 are inserted. Screw into the screw holes 25, 25. Thereby, the attachment of the wiring device to the wiring device mounting body is completed.

  In the state where the wiring device is attached, the wiring space 19 of the cable 61 is formed between the bottom 39 of the restricting portion 33 of the restricting body 31 and the bottom wall 12 of the wiring box 11. The screw 51 shown in FIG. 7 has an appropriate length. However, when the screw 51 is selected too long by mistake, the tip of the screw 51 is positioned at the bottom 39 of the restricting portion 33 of the restricting body 31. The screw 51 is prevented from screwing further. At this time, the screw 51 cannot be screwed any further, and the head of the screw 51 jumps forward from the wall surface to form a gap, and the wiring fixture mounting frame 62 is stuck. You can notice abnormalities in the wearing state. If the screw 51 is too long in this way, it is removed and replaced with another screw 51 for attachment.

Next, the effect | action of the wiring fixture attachment body apparatus 1 is demonstrated.
In the restricting body 31, the restricting portion 33 restricts the tip of the screw 51 that is screwed inside the wiring fixture mounting body from coming into contact with the leading end of the screw 51, so that the initial worker or the like can reduce the wall thickness. Even if different screws are used, even if the same length of screw is always used, the recognition of scratches is insufficient, or careless, even if the screw 51 is too long, It is possible to prevent the screw 51 from being screwed more than the length and the tip portion from contacting and damaging the cable 61 in the wiring box 11.
If the length of the screw 51 is too long, the tip of the screw 51 abuts against the restricting portion 33 and the screw 51 cannot be screwed further. It is possible to alert the beginning worker and the like.

  Further, since the attaching portion 32 of the restricting body 31 is attached to the attaching flange 24 into which the screw 51 of the wiring fixture mounting body is screwed, the restricting body 31 is attached using the place where the screw 51 is screwed. Can be attached. Thereby, the regulation body 31 can be attached compactly in the wiring fixture mounting body, and the regulation body 31 can be prevented from projecting alone in the wiring box 11 and the internal space being narrowed.

  And since the attachment part 32 of the regulation body 31 is attached to the attachment flange 24 which is an instrument attachment part from the direction different from the screwing direction of the screw 51, the regulation body 31 is attached with the screwing of the screw 51. It can be prevented from coming off or coming off easily.

  Furthermore, the contact portion of the attachment portion 32 of the restricting body 31 does not protrude outward from the imaginary line 26 that extends the edge 22 a of the opening 22 of the box cover 21. For this reason, if a part of the contact portion of the attachment portion 32 of the restricting body 31 protrudes outside the imaginary line 26 as shown in FIG. 6B, the wall hole 72 is also restricted. When it is necessary to enlarge the cover to cover the wiring device, it is necessary to enlarge it to avoid interference with the contact part of the body 31, and the wall hole 72 is too large than the decorative cover In this case, a gap is generated in the wall hole 72 and the appearance is deteriorated. However, the regulation body 31 of the present embodiment does not cause such a problem.

  In addition, since the sliding contact preventing portion 34 that prevents the wiring material from entering the screw 51 planned space 20 is provided, the wiring material enters the screw 51 planned screwing space 20 and is screwed. It is possible to prevent the shaft 51 from interfering with and rubbing.

  By the way, in the said embodiment, although the wiring fixture attachment body illustrated what attached the box cover 21 to the wiring box 11, this invention is the same also when the wiring fixture attachment body is the wiring box 11. FIG. Applied. In this case, a screw hole 25 for attaching the wiring fixture mounting frame 62 is provided at a position away from the bottom wall 12 of the peripheral wall 13 of the wiring box 11, and the restricting body 31 is a fixture provided with the screw hole 25. It is attached to the mounting part.

  Moreover, in the said embodiment, although the regulation body 31 is attached separately to the instrument cover part of the box cover 21 or the wiring box 11, the regulation part 33 of the regulation body 31 is attached to the box cover 21 or the wiring box 11. It can also be provided integrally. For example, in the case shown in FIG. 8A, a part of the edge 22 a of the opening 22 of the box cover 21 is bent to the back side of the opening 22 by pressing, and further bent in a direction parallel to the opening 22. The bent portion 41 at the tip is used as the restricting portion 33. When the screw 51 inserted through the screw hole 25 of the box cover 21 is too long, it is prevented from coming into contact with the bent portion 41 and screwing further. Alternatively, as shown in FIG. 8 (b), a protruding piece 42 protruding inside is formed integrally with a part of the peripheral wall 13 of the wiring box 11 by welding, resin molding, engagement or the like of a metal plate, This projecting piece 42 is used as the restricting portion 33. In this manner, when the restricting portion 33 is provided integrally with the box cover 21 or the wiring box 11, it is not necessary to separately prepare the restricting body 31, so that the component cost can be reduced and the component management becomes unnecessary, and the restriction The trouble of attaching the body 31 to the wiring device mounting body can also be saved.

In addition, the sliding contact prevention portion 34 formed in the connecting portion 40 between the attachment portion 32 and the restriction portion 33 of the restriction body 31 of the above embodiment is formed in a cylindrical shape, but the shaft portion of the screw 51 As long as the sliding contact with the wiring member arranged in the wiring device mounting body can be prevented, the shaft portion may not be enclosed in a cylindrical shape, and may be arranged on both sides of the screw 51 as a plate shape.
Furthermore, in the said embodiment, although the regulation body 31 is provided with the sliding contact prevention part 34, when implementing this invention, as shown in FIG. Good.

  And although the regulation body 31 of the said embodiment is attached to the instrument attachment part, it is good also as what is attached to locations other than this. For example, it may be attached to the corner of the opening 22 of the wiring box 11 or the box cover 21, and in this case, the attaching portion 32 of the restricting body 31 is located at a position away from the screwed portion of the screw 51. Therefore, for example, as shown in FIG. 9 (c), the restricting portion 33 has a shape extending in a direction parallel to the bottom wall 12 of the wiring box 11 to a position directly below the shaft portion that is the planned screwing space 20 of the screw 51. Formed.

  In addition, in the above embodiment, the box cover 21 is shown in which one wiring fixture mounting frame 62 is attached to the opening 22. However, for example, two wiring fixture mounting frames 62 are provided in the opening 22. Needless to say, the present invention can also be applied to a mouth mounted in parallel on the left and right. In such a box cover 21, a screw hole 25 for attaching a wiring device is provided at the periphery of the opening 22 in the vicinity of an attachment hole for attaching and fixing the box cover 21 to the wiring box 11. In this case, the regulating body 31 is formed with a relief cutout space or a relief hole in the attachment portion 32 so as not to interfere with the screw 51 inserted through the attachment hole for attaching the box cover 21. Will be.

However, it may be attached by other means such as engagement.

  In addition, the regulation body 31 may be entirely made of a synthetic resin and may be rigid or flexible. Moreover, you may form with another material.

  In addition, in attaching the wiring device to the wiring device mounting body described above, the regulating body 31 is attached to the equipment mounting portion of the box cover 21 after the wall hole 72 is provided in the partition wall 71. The wall holes 72 may be provided after these are installed on the back of the wall with the 31 attached to the box cover 21. In this case, forgetting to attach the regulating body 31 to the box cover 21 can be prevented. Since the regulating body 31 is separate from the box cover 21, if the regulating body 31 interferes with the work when the cable 61 is pulled in and connected, the regulating body 31 is temporarily removed and the cable 61 is pulled in. It can be attached again after the connection.

  Moreover, in the said embodiment, although the regulation body 31 is attached to both of a pair of instrument attachment parts, such as the box cover 21, generally the screw | thread 51 of the same length is used for the instrument attachment part used as a pair. Therefore, only one of the pair of instrument mounting parts, or when there are a plurality of pairs of instrument mounting parts, be careful of the novice worker, etc. even by attaching the regulating body 31 to any one or one of them. Can be aroused. However, since the screws 51 may be attached first to the appliance mounting portion to which the regulating body 31 is not attached, it is desirable that the regulating body 31 is attached to all the appliance mounting portions.

  Furthermore, in the said embodiment, although the regulation body 31 has shown what was attached to the wiring box 11 and the box cover 21 arrange | positioned on the back side of the partition wall 71 or a concrete wall, this invention is shown inside. The present invention can also be applied to outlet fittings, switch fittings, and the like that are attached to ducts into which wiring materials are drawn.
