  In general, when a flat cable having a long width and a short width in the cross section is wired, the direction in which the cable is easily bent is the extending direction of the short width and the cable is difficult to be bent. The direction is a long-width extending direction. For wiring in the back space, it is common to install a cable holder on the stud, hold the cable with the cable holder, and bend the cable toward the wiring box facing the front side of the wall. is there. Therefore, in the wiring path from the cable holder to the wiring box, it is necessary to bend the cable at least on the wall surface side (that is, the front-rear direction orthogonal to the support portion).

  However, in the case where a flat cable having a long width and a short width is held by the first cable holder of Patent Document 1 (the wiring system for the studs in FIG. 13 of Patent Document 1), the long width of the cable is the support portion (support And the short width of the cable is arranged along the vertical direction perpendicular to the support portion. That is, the easy bending direction of the flat cable held by the cable holder is the vertical direction, and the difficult bending direction is the front-back direction. Therefore, when wiring the cable by bending it to the front side of the wall, the cable must be forcibly twisted to form a wiring path in order to bend the cable in a direction in which bending is difficult.

  On the other hand, when the flat cable is held by the second cable holder of Patent Document 1 (the wiring system for the studs in FIG. 18 of Patent Document 1), the long width of the cable is the front surface of the construction material (or the standing wall surface). ) And the short width of the cable is arranged along the front-rear direction (wall surface direction). That is, the easy bending direction of the flat cable held by the cable holder is the front-rear direction, and the difficult bending direction is the left-right direction (the direction away from the construction material). With this cable holder, the cable can be easily bent in the wall surface direction. However, since the direction away from the construction material is the direction in which the cable is difficult to bend, when forming a wiring path at a location away from the construction material, the cable is forced to bend in the same direction that is difficult to bend. The wiring path had to be formed by twisting.

  When the cables are twisted and wired as in the conventional cable holder, the cables are entangled with each other due to the twisted cables, and the wiring work or the wiring route may be complicated. Alternatively, the cable may be disconnected due to twisting, or a load may be applied to the cable terminal due to a force that recovers from twisting of the cable, so that the wiring structure may be fragile. Accordingly, there is a need for a cable holder and a wiring device that can form a wiring path without bending the cable in the direction that is difficult to bend as much as possible when wiring a cable having an easy-bend axis and a difficult-bend axis in the radial direction behind the wall. It has been.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a cable holder and a wiring device that hold a cable on the back of the wall so that wiring can be performed more easily and reliably.

As shown in FIGS. 3 and 4, the support 110 is a long plate having an L shape in plan view that extends from the base end to the tip, and is disposed at the base end so as to contact the side surface P <b> 1 of the construction material P. And a support portion 112 extending in a longitudinal direction from the fixed portion 111 toward the tip (or the side of the construction material P). In other words, the support body 110 is bent in an L shape, and the short piece-like fixing portion 111 and the long piece-like support portion 112 are connected at a substantially right angle.

  In addition, three first fixing holes 111a are formed in the fixing portion 111, and can be fixed to the side surface P1 of the construction material P through part or all of the first fixing holes 111a. The support portion 112 has a plurality of long holes 112a for fixing the wiring box. Further, a plurality of T-shaped fitting holes 114 are arranged along the longitudinal direction above and below the plurality of long holes 112a. The fitting hole 114 is used for fixing the engaging claw 126 of the holding body 120. The fitting hole 114 has a wide portion 114a extending in the longitudinal direction, and a narrow portion 114b continuously provided upward or downward at the approximate center of the wide portion 114a. As will be described later, the wide portion 114a is formed with a width that fits the wide first protrusion 126a of the engaging claw 126, while the narrow portion 114b can be fitted with the narrow second protrusion 126b. It is formed with a wide width. In addition, in the cable holder 100 of this embodiment, the long hole 112a is not used.

  Further, as shown in FIGS. 3 and 4, the support body 110 includes a protruding portion 113 that can selectively protrude laterally from the fixed portion 111 so as to contact the front surface P <b> 2 of the building material P. The protruding portion 113 is a rectangular plate piece formed inside the fixed portion 111. The projecting portion 113 connects the projecting portion 113 and the fixed portion 111 so that the projecting portion 113 and the fixed portion 111 can rotate (or refract) so as to abut on the front surface P2 of the construction material P facing the support portion 112 side.

  In addition, although the support body 110 of this embodiment was obtained by bending and punching a SUS material, this invention is not limited to the manufacturing method and material of one Embodiment. For example, instead of a metal material such as SUS material, it is possible to form a support by molding a hard resin or the like. In this embodiment, the support 110 is fixed to the construction material P in a cantilever state via the fixing portion 111. However, the support is provided at both ends of the support portion, and the support is placed between the two construction materials. It is also possible to fix it in a both-sided state (see FIG. 20).

  FIG. 5 is a perspective view of the holding body 120, and FIGS. 6A to 6D are a side view, a front view, a rear view, and a plan view of the holding body 120. As shown in FIGS. 5 and 6, the holding body 120 includes a rectangular plate-shaped base 121, a comb-shaped holding portion 122 integrally formed on the lower half of the front surface of the base 121, and a back surface of the base 121. And a hooking portion 123 integrally coupled. A relatively large rectangular opening 121 a is formed in the upper half portion of the base 121. The opening 121a is formed in such a size that the surface of the support portion 112 can be visually recognized from the front side of the wall through the opening 121a when the holding body 120 is hooked on the support body 110. Further, both side edges of the base part 121 are partially cut out, and a cut out part 121b is formed so that a minus driver D described later can be easily inserted into the fitting hole 114.

  The holding portion 122 includes a side wall 122a erected substantially vertically on one of the left and right sides of the base 121, and a plurality of nippings arranged side by side so as to extend substantially vertically (parallel to the front surface of the base 121) from the side wall 122a. A piece 122b and a holding claw 122c for retaining the cable C formed so as to bulge in the front-rear direction at the tip of each holding piece 122b are provided. A pair of sandwiching pieces for sandwiching the side surface of the cable C is formed by two adjacent sandwiching pieces 122b, and a cable housing space 122d is defined therebetween. The interval between adjacent sandwiching pieces 122b is preferably slightly smaller than the short width w2 of the cable C to be sandwiched, and is slightly elastically deformed so as to open when the cable C is inserted, and the elastic restoring force sandwiches the side surface of the cable C. Pressure is possible. In this embodiment, the holding part 122 has four clamping pieces 122b and three cable housing spaces 122d.

  Fig.7 (a) is AA sectional drawing of FIG.6 (b), FIG.7 (b) is the elements on larger scale. 8A is a cross-sectional view taken along line BB in FIG. 6B, and FIG. 8B is a partially enlarged view thereof. As shown in FIG. 7, the hook portion 123 is integrally coupled to the rear surface of the base portion 121 via the coupling portion 122. The hook portion 123 includes a thin plate-like hook plate 124 extending vertically, a coupling portion 125 integrally connected to the outer surface of the base 121 near the upper edge of the hook plate 124, and a front portion near the lower end of the hook plate 124. And an engaging claw 126 that protrudes. A thin portion 124a extending in the width direction is recessed in the upper part of the front surface of the hooking plate 124 (in the vicinity of the coupling portion 125). The thin portion 124 a is formed thin along the lateral width direction of the engagement plate 124 and functions to assist the opening and closing operation of the engagement plate 124 before and after. The hooking plate 124 is formed with a hole 124b drilled at a substantially central position where it can communicate with the opening 121a of the base 121.

  Next, with reference to FIG.7 and FIG.8, the form of the engaging claw 126 formed in the lower end (or front-end | tip) of the latching board 124 is demonstrated in detail. The front end (lower end) of the engaging claw 126 is formed in a tapered shape, and a front end inclined surface 126c facing forward is provided on the lower surface side of the engaging claw 126. The tip inclined surface 126c is provided with a recess 126c1 in a part in the width direction. And since the front-end | tip of the engaging nail | claw 126 was formed in the taper shape, it is possible to latch the holding body 120 on the support part 112 of the support body 110 easily.

  Further, the engaging claw 126 includes a wide first protrusion 126a protruding forward and a narrow second protrusion 126b connected to the first protrusion 126a at the upper center. As shown in FIG. 7B and FIG. 8B, the first protrusion 126 a is formed with a width that can be fitted into the wide portion 114 a of the T-shaped fitting hole 114 of the support 110. Further, the upper surface 126a1 of the first protrusion 126a extends at an angle orthogonal to the hooking plate 124. The upper surface 126a1 functions to prevent the first protruding portion 126a fitted to the wide portion 114a from coming out upward. Further, the side edge 126a2 of the first protrusion 126a is chamfered and inclined. On the other hand, the 2nd protrusion part 126b is formed in the narrower width | variety which can be fitted in the narrow part 114b of the fitting hole 114. FIG. Similarly, the side edge 126b2 of the second protrusion 126b is chamfered and inclined. As will be described later, the side edges 126a2 and 126b2 formed in an inclined shape assist the side slide when the engaging claw 126 engaged with the inner edge of the fitting hole 114 is disengaged. The work of removing 120 is facilitated.

  In addition, although the holding body 120 of this embodiment is a thing shape | molded with the synthetic resin, the holding body of this invention is not limited to this. For example, the holding body can be made of metal, and those skilled in the art can arbitrarily configure the material and the like.

  FIG. 9 is an exploded perspective view of the cable holder 100. As shown in FIG. 9, the cable holder 100 can be constructed by arranging the holding body 120 so as to hang from the orthogonal direction with respect to the support portion 112 of the support body 110. More specifically, the latching process will be described. When the holding body 120 is latched to the support portion 112, the tip inclined surface 126c is brought into contact with the upper end surface of the support portion 112, and the support portion is supported with respect to the tip inclined surface 126c. By sliding the 112 relatively up and down, the hook plate 124 can be rotated backward (elastically deformed) (elastically deformed) (with the thin-walled portion 124a as an axis) to easily open the tip of the hook portion 123. When the engaging portion 123 is further pushed down with respect to the support portion 112, the engaging plate 124 is elastically restored and the engaging claw 126 is disposed in the fitting hole 114 as the engaged portion. As a result, a part of the support part 112 is disposed between the base part 121 and the hooking plate 124 via the opening part formed at the lower end of the hooking part 123.

  10A to 10C, the holding body 120 is latched on the support body 110, and the engaging claw 126 of the engaging portion 123 is fitted into the fitting hole 114 of the support body 110, so that the holding body 120. The top view of the state which attached to the support part 112 so that attachment or detachment was possible, the CC sectional drawing and DD sectional drawing are shown. As shown in FIGS. 10A to 10C, the wide first protrusion 126a of the engaging claw 126 is disposed in the wide part 114a of the fitting hole 114, and the narrow second protrusion 126b. Is disposed in the narrow portion 114 b of the engagement hole 114. Since the first and second protrusions 126a and 126b and the wide portion 114a and the narrow portion 114b of the fitting hole 114 are formed with substantially the same width in the width, they are in a fitting relationship. . Further, as shown in FIG. 10C, the upper surface 126a1 of the engaging claw 126 is engaged with the upper end surface of the fitting hole 114 (wide portion 114a), and the first protrusion 126a fitted to the wide portion 114a. Is restricted from coming out upward. That is, the holding body 120 is firmly hooked to the support portion 112 unless this fitting relationship is released. Further, in this fixed state, a screw (not shown) is screwed from the front into the hole 124 b formed in the engaging portion 123 and the narrow portion 114 a of the fitting hole 114, so that the holding body 120 is strengthened by the support body 110. You may connect to. In the present embodiment, in order to fix the support 110 to the left side construction material P, one fitting hole 114 located on the upper side is used. However, when fixing the support body 110 to the right side construction material P, the other fitting hole 114 can be arrange | positioned above by reversing the support body 110 right and left. That is, by arranging the upper and lower fitting holes 114 symmetrically with respect to the central axis extending in the longitudinal direction, the support body 110 can be similarly installed on either the left or right construction material P. .

  Next, with reference to FIG.11 and FIG.12, the operation | movement which cancels | releases the fitting state of FIG. 10, and removes the holding body 120 from the support body 110 and its process are demonstrated. As shown in FIG. 11 (a), the front end of the flathead screwdriver D is vertically positioned along the notch 121b, and both the wide portion 114a and the narrow portion 114b of the fitting hole 114 are from the front (or may be the back). Insert. Next, from the state of FIG. 11A, the minus driver D is rotated, and the side wall of the holding body 120 is pressed to the side (longitudinal direction of the support portion 112) with the tip of the minus driver D. Side force is applied to the holding body 120 such that the first and second protrusions 126a and 126b of the engaging claw 126 fitted into the fitting hole 114 get over the side edge of the fitting hole 114. The engagement claw 126 is lifted rearward from the fitting hole 114 and detached. At this time, since the side edges 126a2 and 126b2 of the first and second protrusions 126a and 126b are both chamfered, the first and second protrusions 126a and 126b are locked to the side edges of the fitting hole 114. It is possible to smoothly ride on the back surface of the support portion 112 without being done. In this release process, the narrow portion 114b of the fitting hole 114 functions as a release portion for inserting the flat screwdriver D, and the holding body 120 is effectively forced by using the flat screwdriver D and the narrow portion 114b. Can be communicated. However, instead of the minus driver D, other means for applying a lateral force may be employed.

  FIGS. 12A to 12C are a plan view, a EE cross-sectional view, and a FF cross-sectional view showing a state in which the flat-blade screwdriver D is pulled out from the state shown in FIG. 11B. As shown in FIGS. 12B and 12C, a part of the first and second protrusions 126 a and 126 b of the engaging claw 126 rides on the back surface of the support portion 112. At this time, the hooking plate 124 rotates rearward with the thin portion 124a as an axis, and an open portion is formed at the lower end thereof. And from this state, the holding body 120 can be removed from the support body 110 through the open part by pulling the holding body 120 upward from the support section 112.

  That is, in the present embodiment, the holding body 120 can be easily fixed to the support portion 112 by simply engaging the holding body 120 with the support body 110 to fit the engaging claw 126 into the fitting hole 114, and The holding body 120 can be easily removed as needed by sliding the holding body 120 sideways with respect to the support portion 112. That is, in this embodiment, the holding body 120 is detachable from the support body 110, and the workability thereof is greatly improved.

  FIG. 13 is a perspective view illustrating an installation structure in a state where the wiring device 10 including the cable holder 100 and the wiring box 130 is installed on the construction material P behind the wall and the cable C is wired. In FIG. 13, the wall material WF and the wiring device E are omitted for convenience of explanation. As shown in FIG. 13, the support body 110 of the cable holder 100 is fixed to the side surface P1 of the construction material P via the fixing portion 111, and the wiring box 130 is directly below the cable holder 100. It is fixed to the side surface of the construction material P via the peripheral wall 131. The wiring box 130 includes a peripheral wall 131, a side wall 132, and an opening 133. A plurality of insertion holes 131 a for inserting the cable C are provided on one surface (upper surface) of the peripheral wall 131 of the wiring box 130. In addition, a plurality of fixing holes 131b are provided on one surface (side surface) of the peripheral wall 131 of the wiring box 130. By driving a screw into the side surface of the construction material P through the fixing holes 131b, the wiring box 130 is formed. It is directly fixed to the construction material P. Further, a detected part 134 projects from the approximate center of the bottom wall 132. This detector 134 can be detected by a magnetic detector from the wall surface, is used to specify the position of the hole H, and is removed as necessary after the hole is drilled. The wiring box 130 may be a general-purpose wiring box, and various wiring boxes can be selected.

  As shown in FIG. 13, the cable C is held by the holding portion 122 of the holding body 120 supported by the support portion 112. In the longitudinal direction of the support portion 112, the cable holder 100 holds the cable C so that the position of the holding portion 122 corresponds to the position of the insertion hole 131 a of the wiring box 130. In other words, the holding body 120 is appropriately attached to the support body 110 so that the position of the wiring source holding section 122 on the longitudinal axis of the support section 112 matches the position of the wiring destination insertion hole 131a.

  14 is a longitudinal sectional view of a structure in which wall materials WF and WR are erected on the installation structure of FIG. As shown in FIGS. 13 and 14, the cable C is inserted into the wiring box 130 through the insertion hole 131 a and bent to the opening 133. And the cable C is connected to the wiring location of wiring appliances E, such as an outlet socket and a switch attached to the appliance attachment hole 133a, through the perforation H of the wall material WF. Although the final wiring destination of the cable C in the present embodiment is the wiring device E, the insertion hole 131a of the wiring box 130 in front of the cable C can also be interpreted as a wiring target.

  15 is a cross-sectional view taken along the line GG in FIG. With reference to FIG. 15, the form which clamps the cable C and the bending direction of the cable C are demonstrated in detail. As shown in FIG. 15, the cable C is a flat cable having a substantially oval cross section in which two cores arranged in parallel are covered with a shield material and a covering material. Short width w2 (<w1). In the radial direction of the cable C, the direction orthogonal to the long width w1 (or the extending direction of the short width w2) is the direction in which the cable C is easily bent, and this is defined as the easy bending axis c1. On the other hand, the direction orthogonal to the short width w2 of the cable C (or the extending direction of the long width w1) is the direction in which the cable C is difficult to bend, and this is defined as the difficult to bend axis c2. The bendable axis c1 indicates a direction that is relatively easy to bend in the radial direction of the cable C (or compared to the bendable axis c2), and bends at least along the easy bend axis c1 without twisting the cable C. can do.

  The side surface of the cable C on the side of the long width w1 is sandwiched between the pair of sandwiching pieces 122b of the holding body 120, and the cable C is housed in the housing space 122d so as not to fall off sideways by the sandwiching claws 122c. At this time, the side surface of the cable C on the long width w1 side is disposed along the longitudinal direction of the support portion 112, and as a result, the easy-bend axis c1 is disposed so as to be orthogonal to the longitudinal axis of the support portion 112. That is, in a state where the cable C is supported by the holding portion 120, the cable C is easily bent in the direction perpendicular to the longitudinal axis of the support portion 112, while it is difficult to bend in the longitudinal direction of the support portion 112.

  In the wiring device 10 (the cable holder 100 and the wiring box 130) of the present embodiment, the holding portion 122 and the insertion hole 131a of the wiring box 130 in the longitudinal direction of the support portion 112 (or the direction away from the construction material side surface P1). Because of the corresponding position, the cable C can be routed from the cable holder 100 to the wiring box 130 without bending the cable C in the direction of the difficult bending axis c2 as shown in FIG. That is, the holding body 120 (holding portion) so that the distance from the construction material side surface P1 to the insertion hole 131a (wiring destination) of the wiring box 130 matches the distance (wiring source) from the building material side surface P1 to the holding portion 122. 122) is adjusted along the support portion 112, and the cable C is held by the cable holder 100, so that the cable C is bent only in the easy bending axis c1 direction and twisted in the difficult bending axis c2 direction. Therefore, the wiring path can be optimally formed.

  In the embodiment shown in FIGS. 13 to 15, the installation structure in which the insertion hole 131 a of the wiring box 130 is arranged immediately below the holding portion 122 has been described, but the present invention is not limited to this. For example, the holding portion and the insertion hole can be arranged so as to be greatly separated in the direction orthogonal to the longitudinal axis of the support portion. The cable held so that the easy bending axis c1 is orthogonal to the support portion can be bent freely (360 degrees) in the plane orthogonal to the longitudinal axis of the support portion, so that the holding portion and the insertion hole are orthogonal to the longitudinal axis. Even if they are greatly separated in the direction, the wiring path can be optimally formed without twisting in the direction of the difficult bending axis c2. Alternatively, even if the position of the holding portion does not match the position of the insertion hole in the longitudinal direction of the support portion, the holding portion and the insertion hole are made to be as close as possible along the longitudinal axis of the support portion. Thus, it is possible to optimize the wiring route so that the bending amount in the direction of the easy bending axis c1 is maximized and the bending amount in the direction of the difficult bending axis c2 is minimized and the cable C is not twisted as much as possible.

  Next, a method for constructing an installation structure in which the cable C is wired by the wiring device 100 will be described with reference to FIG. FIG. 16 is an exploded perspective view of the installation structure of FIG. 13 (and FIG. 14).

  First, the height for fixing the support 110 (cable holder 100) is set, and the position where the fixing portion 111 of the support 110 is arranged is marked on the construction material side surface P1. In accordance with this ruled line, the staple 113f is partially driven into the construction material side surface P1, and then the head of the staple 113f is inserted into the proximal end (the distal end of the protruding portion 113) of the U-shaped peripheral groove 113d. The fixing portion 111 is disposed so as to abut (or approach) the construction material side surface P1. And the fixed part 111 is slightly slid to the back of the construction material P so that the protrusion part 113 may be inserted between the staple 113f and the construction material side surface P1 from this state. At this time, the fixing portion 111 is temporarily fixed by the staple 113f so as not to fall on the side surface P1 of the construction material, and the staple 113f can be relatively moved in the circumferential groove 113d, so that the support 110 itself can slide back and forth. is there. Next, the support body 110 is positioned forward and backward by sliding the fixing portion 111 back and forth along the construction material side surface P2. Subsequently, the fixed portion 111 of the support 110 can be fixed to the construction material side surface P1 by driving the staple 113f into the construction material side surface P1 in this positioned state. Alternatively, instead of the staple 113f or together with the staple 113f, the support 110 is attached to the construction material P by driving a screw 111b (virtual line) into the construction material side face P1 through the first fixing hole 111a of the fixing portion 111. It may be fixed.

  On the other hand, the height for fixing the wiring box 130 is set in accordance with the position (height) of the through hole H provided in the wall material WF, and the position where the wiring box 130 is arranged is marked on the construction material side surface P1. The peripheral wall 131 of the wiring box 130 is directed to the construction material side surface P1 along the ruled line, and the wiring box 130 is fixed to the construction material P by passing a screw through the fixing hole 131b on the construction material side surface P1.

  Subsequently, the fitting hole 114 of the support body 110 corresponding to the position spaced from the construction material side face P1 of the insertion hole 131a of the wiring box 130 is selected from the plurality of fitting holes 114, and the holding body 120 is supported by the support portion 112. The engaging claw 126 is fitted into the fitting hole 114 from the orthogonal direction (above). In this way, the holding portion 122 is fixed in a detachable state at a predetermined position of the support portion 112 (in this embodiment, the position is directly above the insertion hole 131a but is closest to the wiring destination target in the longitudinal direction). be able to. Further, in a state where the cable holder 100 is installed on the construction material P, the cable C is inserted into the accommodation space 122d so that the side surface of the cable C on the long width w1 side is clamped by the clamping pieces 122b of the holding unit 122. Then, the cable C held by the holding portion 122 is inserted into the wiring box 130 through the insertion hole 131a while being bent only in the direction of the easy bending axis c1.

  Next, although not shown here, the cable holder 100 and the wiring box 130 are installed on the construction material P, the cable C is temporarily fixed by the holding portion 122, and then the wall materials WF and WR are constructed before and after the construction material P. Then, one or a plurality of oval perforations H having a predetermined size are formed in a predetermined position of the wall material WF using a hole saw or the like from the wall surface space. In general, the drilling position is determined by addressing a magnetic detector from the front side of the wall and magnetically detecting the detected part 134 of the wiring box 130. After the drilling, the detected part 134 is removed.

  Finally, (after the wall material WF is erected), the installation structure is constructed by connecting the wiring fixture E from the wall surface to the wiring location of the wiring fixture E and attaching the wiring fixture E to the fixture mounting hole 133a of the wiring box 130 with a screw. Is possible.

  FIG. 17 shows another usage example of the cable holder 100. As shown in FIG. 17, when the body edge material M is fixed to the front surface P <b> 2 of the construction material P, the projecting portion 113 of the support 110 projects sideways and is fixed to the construction material front surface P <b> 2. The cable holder 100 can be moved forward and installed by the thickness of the edge material M. In the installation method of the cable holder 100 in FIG. 17, the protruding portion 113 is bent about the hinge portion 113 b in the direction opposite to the extending direction of the support portion 112, and protrudes laterally from the fixing portion 111. The outer surface of the fixed portion 111 is brought into surface contact with the side surface P1 of the construction material P, and the contact surface 113a of the projecting portion 113 orthogonal to the outer surface of the fixed portion 111 is brought into surface contact with the front surface P2 of the construction material P, thereby supporting Maintain the posture of the body 110. With this posture, the support 110 can be fixed to the construction material P by passing the screw through the second fixing hole 113c of the protrusion 113 and hitting the construction material front surface P2.

  As shown in FIG. 18, it is also possible to attach a resin mounting base 140 to the fixing portion 111 of the support 110 as a separate body. The mounting base 140 includes a mounting portion 141 that is mounted on the fixed portion 141 and a second protruding portion 142 that protrudes laterally from the mounting portion 141. The mounting portion 141 is provided with a clamping claw 141a for clamping the upper and lower side edges of the fixing portion 111, and a protrusion 141b that is inserted into the second fixing hole 113c of the protruding portion 113 and prevents the mounting portion 141 from being displaced. It has been. The mounting base 140 is attached to the support 110 when the protruding portion 113 does not protrude sideways. That is, by mounting the mounting base 140, the mounting portion 141 is brought into contact with the construction material side surface P1, and the second projecting portion 142 is brought into contact with the construction material front surface P2, thereby positioning and fixing the support 110. Can be made even simpler.

  Hereinafter, the effects of the cable holder 100 and the wiring device 10 according to an embodiment of the present invention will be described.

  According to the cable holder 100 and the wiring device 10 of the present embodiment, by inserting the holding portion 122 of the holding body 120 at a predetermined position of the support portion 112 of the support body 110, the insertion hole of the wiring box 130 that is the wiring destination is provided. The cable C can be held in a state separated from the building material P along the longitudinal axis of the support portion 112 so as to correspond to the position of 131a. Further, the holding portion 122 can hold the cable C so that the easy bending axis c1 of the cable C is orthogonal to the longitudinal axis of the support portion 112. Thus, when forming a wiring path from the holding portion 122 to a desired wiring location (the insertion hole 131a of the wiring box 130 or the wiring device E), the cable C is easily bent in the c1 direction (the direction orthogonal to the longitudinal axis of the support portion 112). ), The cable C can be wired without twisting the cable C2 in the direction in which the cable C is difficult to bend (longitudinal direction of the support portion 112). That is, according to the cable holder 100 of the present embodiment, the bending amount of the cable C along the easy-bend axis c1 of the cable C is maximized, and the bending amount of the cable C along the hard-bending axis c2 of the cable C is maximized. Therefore, the wiring route can be optimized so as to minimize the twisting of the cable C. Accordingly, the cable C held by the holding portion 122 can be bent without twisting on a plane orthogonal to the longitudinal axis of the support portion 112, so that the position along the longitudinal axis of the holding portion 122 is set at the wiring box 130. The wiring path of the cable C from the holding portion 122 to the insertion hole 131a or the wiring device E is optimized by appropriately determining the position according to the position of the wiring destination (the insertion hole 131a or the wiring device E). C can be held easily and reliably (without twisting as much as possible).

  In the present embodiment, the cable C can be wired without forcibly twisting as much as possible, and the wiring work due to the entanglement between the cables C or the complicated wiring route, the disconnection of the cable C due to the twist, and the wiring structure due to the burden on the cable terminal The problem of the conventional cable holder such as weakening of the cable is solved.

(Modification 1)
In the cable holder 100 of the above-described embodiment, one holding body 120 is attached to one support body 110, but the present invention is not limited to this. For example, in the wiring device 20 and the cable holder 200 in FIG. 19, a plurality of (four) holding bodies 220 are attached to one supporting body 110. In the wiring device 20, the configurations of the support 210, the holding body 220, and the wiring box 230 are the same as the configurations of the support 110, the holding body 120, and the wiring box 130 described above, and thus the description thereof is omitted. As shown in FIG. 19, a plurality of holding bodies 220 are juxtaposed along the support portion 212 of the support body 210, and the positions of the holding portions 222 are the insertion holes 231 a of the wiring box 230 in the longitudinal direction of the support portion 210. Corresponds to the position of. The four cables C are respectively held by the holding portions 222 and are wired in the wiring box 130 through the insertion holes 231 a of the wiring box 130. These cables C form a wiring path without being bent in the direction of the difficult bending axis c2. Therefore, in this embodiment, it is possible to deal with a plurality of cables while exhibiting the same effects as in the embodiment.

(Modification 2)
In the wiring device 10 of the above-described embodiment, the cable holder 100 is installed in a cantilever state on one of the construction materials P, but the present invention is not limited to this. The wiring device 30 of FIG. 20 holds both the holding body 320 and the wiring box 330 so as to be movable laterally (in the direction in which the building material P is separated) between the two building materials P. The wiring device 30 includes a support 310, a holding body 320, a wiring box 330, and an arrangement support 340. The support 310 and the wiring box 330 of this embodiment are partially common to the configurations of the support 110 and the wiring box 130 of the embodiment, and the holding body 320 is the holding of the embodiment. It has the same structure as the body 120. The description of these common configurations is omitted.

  In the present embodiment, the cable holder 300 includes a support body 310 having a long support section 312 having a length spanning the two fixed sections 311 and the two construction materials P at both ends, and the support section 310. And a holding body 320 to be attached. In addition, the wiring box 330 is supported by an arrangement body support tool 340 provided between the two construction materials P similarly to the support body 310, and is slidable along the second support portion 342. The fixed position can be arbitrarily selected. The arrangement body support 340 has the same shape and structure as the support body 310 on which the holding body 320 is supported, and fixes the wiring box 330 to the support portion 342 with screws through the long holes 342a.

  In this embodiment, the wiring box 330 is arranged at a desired position along the longitudinal direction, and the holding body 320 is arranged so that the position of the holding body 320 is directly above (on the longitudinal axis) of the wiring box 330. It can be moved along the support part 310. In the support portion 310, the wide portion 314 a of the fitting hole 314 is continuously provided in the longitudinal direction, so that the holding body 320 can be slid sideways while being hooked on the support portion 312. The holding body 320 is fixed on the support portion 312 by fitting the narrow second protrusion 326 b of the engagement claw 326 into the narrow portion 314 b of the fitting hole 314 of the support portion 312. In other words, since the holding portion 322 can move along the longitudinal direction of the support portion 312, the position of the holding portion 322 can be easily adjusted along the support portion 312.

  That is, in this embodiment, the attachment position of the holding portion 322 can be changed stepwise between the construction materials P according to the positions of the plurality of narrow portions 314b of the fitting hole 314. Therefore, as long as the space is between the building materials P, even if the wiring box 330 is disposed at any location, the cable C is bent in the direction of the axis c2 that is difficult to bend by appropriately selecting the fixing position of the holding portion 322 corresponding thereto. The cable C can be effectively wired by being bent only in the direction of the easy bending axis c1 (the direction orthogonal to the longitudinal axis) without bending the cable C.

  In the above-described embodiment, the support body (support section) and the holding body (holding section) are formed as separate bodies. However, if the position of the holding section on the support section is set in advance, the support section and the holding section Can be formed integrally.

  Therefore, the present invention is not limited to the above-described embodiments and modifications, and can be implemented in various modes as long as they belong to the technical scope of the present invention.
