Description

Stratum holder and striatum fixator

[0001] The present disclosure relates to a wire holder and a wire fastener.

[0002] Conventionally, there has been known a technique for laying a wire inside various structural members, including industrial robots (see, for example, Patent Document 1). In the technique described in Patent Document 1, a coaxial connector connected to one end of the wire is fixed to a fixing jig, and the fixing jig is installed inside a tower cover of a tower-type antenna.

[0003] JP 2013-31002 A

[0004] When wiring a wire inside a structural member via a through-hole that penetrates the wall of the structural member from the inside to the outside, it may not be possible to attach the fixing member to the wire in advance depending on the size relationship between the hole and the fixing member. In that case, the wire must be passed through the through-hole before being attached to the fixing member, so it is difficult to determine whether the wire is twisted after passing it through the through-hole. Furthermore, when wiring multiple wires, it is difficult to determine whether the wires are tangled in addition to whether each wire is twisted.

[0005] Furthermore, even when a wire is routed through a wall of a structural member without passing through a through-hole, it is difficult to determine whether the wire is twisted or not depending on the appearance of the wire. If one or more wires are routed through a structural member in a twisted or tangled state, excessive load will be placed on the wire due to the twist. In particular, when a wire is routed through a movable structural member, even a slight twist during routing can cause excessive load to be placed on the wire when the structural member moves, resulting in a break. Therefore, it is desirable to be able to route one or more wires through the interior or wall of a structural member without twisting or tangling.

[0006] One aspect of the present disclosure is a wire holder that is fixed to one or more wires near an attachment position to the structural member at a midpoint in the longitudinal axis direction so as not to be rotatable around the longitudinal axis in order to wire the wires inside or within the wall of the structural member, the wire holder having a contact surface that contacts the wires and a phase recognition unit that indicates the phase of the wires attached to the structural member at the attachment position around the longitudinal axis, the contact surface comprising at least a portion of the circumferential surface of a cylindrical inner surface.

[0008] [First embodiment] A wire member holder and a wire member fastener according to a first embodiment of the present disclosure will be described below with reference to the drawings. As shown in Fig. 1, the wire member fastener 1 according to this embodiment includes two wire member holders 11 for wiring one or more wire members 3 inside various structural members such as industrial robots, and two auxiliary fastening members 7 to which the wire member holders 11 are detachably attached.

[0009] The structural member is not limited to an industrial robot, and is not particularly limited as long as it is installed with the wire body 3. The structural member may be a fixed part installed on the floor surface, or a movable part that moves relative to the fixed part.

[0010] The structural member has a hollow hole (through hole) 9 that penetrates the wall from the inside to the outside. The umbilical member 3 is wired inside the structural member via the hollow hole 9. In the case of an industrial robot, for example, the hollow hole 9 may be a cast hole provided in a cast part that constitutes the robot, such as a base (fixed part), a rotating body (movable part), or an arm (movable part), an open gap between two wall surfaces of the cast part, or a gap between a wall surface of the cast part and the outer surface of a motor provided in the robot.

[0011] The wire holder 11 is fixed near a mounting position to a structural member at a midpoint in the longitudinal direction of the wire 3. The mounting positions of the wire 3 to the structural member are positions that are located outside the openings at both ends of the hollow hole 9 when the wire 3 is wired inside the structural member via the hollow hole 9, for example.

[0012] One of the attachment positions in the longitudinal direction of the wire body 3 is attached by one of the wire body holders 11, for example, near the opening of the hollow hole 9 on the inner wall surface of the structural member. The other attachment position in the longitudinal direction of the wire body 3 is attached by the other wire body holder 11, for example, near the opening of the hollow hole 9 on the outer wall surface of the structural member.

[0013] 2, each wire member holder 11 is formed in a cylindrical shape from an elastically deformable material such as resin or rubber, and has a through-hole 11a that penetrates in the longitudinal direction. Each wire member holder 11 also has a rectangular flat surface (phase recognition portion, flat surface, mounting surface) 11b, which is formed by cutting out a portion of the outer circumferential surface from one end to the other in the longitudinal direction. By fixing the wire member holder 11 to the wire 3, the position of the flat surface 11b of the wire member holder 11 can be used as an index to determine the phase around the longitudinal axis of the wire member 3 that is attached to the structural member.

[0014] The wire holder 11 also has a slit 11c extending longitudinally from one end to the other end in a portion of its circumferential direction. In the example shown in Fig. 2, the slit 11c is provided in the flat surface 11b. The slit 11c penetrates from the surface of the flat surface 11b to the inner circumferential surface of the through-hole 11a. The slit 11c need only be provided in a portion of the circumferential direction of the wire holder 11, and is not limited to being provided on the flat surface 11b.

[0015] The filament holder 11 accommodates the filament 3 at a midpoint in the longitudinal direction in the through-hole 11a with the slit 11c open by elastic deformation, and then by closing the slit 11c, it is positioned in a state where it surrounds the midpoint in the longitudinal direction of the filament 3.

[0016] The through hole 11a has an inner diameter that is approximately the same as or slightly smaller than the outer diameter of the filament 3. The through hole 11a also has a contact surface 11f that comes into contact with the filament 3. The contact surface 11f comprises at least a portion of the cylindrical inner surface in the circumferential direction. In the example shown in FIG. 2, the entire circumferential area of ​​the inner surface of the through hole 11a serves as the contact surface 11f. The filament holder 11 has an outer diameter that is smaller than the inner diameter of the hollow hole 9 when attached to the filament 3.

[0017] The wire holder 11 also has one or more cable grooves (grooves for the first bundling member) 11d extending circumferentially on its outer circumferential surface. In the example shown in Fig. 2, two cable grooves 11d are provided on the outer circumferential surface excluding the flat surface 11b of the wire holder 11. The two cable grooves 11d are formed at an interval from each other in the longitudinal direction of the wire holder 11.

[0018] The cable groove 11d also functions as an attachment position recognition portion that indicates the attachment position of the wire 3 in the longitudinal direction relative to the structural member. Instead of the cable groove 11d, the longitudinal end surface of the wire holder 11 may be used as the attachment position recognition portion.

[0019] The wire body fixing device 1 includes first cable ties (first bundling members) 13 that fix the wire body holders 11 to the wire body 3, respectively. The first cable ties 13 are, for example, nylon bands. The first cable ties 13 are wound around the cable grooves 11d of the wire body holders 11 attached to the wire body 3. This tightens the wire body holders 11 radially inward, thereby fixing the wire body holders 11 to the wire body 3 so that they cannot rotate around the longitudinal axis of the wire body 3.

[0020] 1, each auxiliary fixing member 7 is made of, for example, a long, thin metal plate. Each auxiliary fixing member 7 has a fixing portion 7a provided at one end in the longitudinal direction, an attachment portion 7b provided at the other end in the longitudinal direction, and an intermediate portion 7c connecting the fixing portion 7a and the attachment portion 7b.

[0021] The auxiliary fixing member 7 has a shape in which the fixing portion 7a and the mounting portion 7b are bent in opposite directions in the plate thickness direction relative to the intermediate portion 7c. The fixing portion 7a and the mounting portion 7b extend parallel to each other with a shift in position in the plate thickness direction, and the intermediate portion 7c extends obliquely in the plate thickness direction relative to the fixing portion 7a and the mounting portion 7b.

[0022] The surface of the fixing portion 7a opposite to the mounting portion 7b is fixed to the inner or outer wall surface of the structural member with an adhesive or bolts. The surface of the mounting portion 7b opposite to the fixing portion 7a is flat and forms a mounting surface that comes into contact with the flat surface 11b of the wire holder 11.

[0023] The operation of the wire holder 11 and wire fixture 1 according to this embodiment configured as described above will be described below. To wire the wire 3 to a structural member using the wire holder 11 and wire fixture 1 according to this embodiment, first, the fixing portion 7a of one auxiliary fixing member 7 is fixed to the inner wall surface of the structural member near the opening of the hollow hole 9 with an adhesive or bolts. Similarly, the fixing portion 7a of the other auxiliary fixing member 7 is fixed to the outer wall surface of the structural member near the opening of the hollow hole 9 with an adhesive or bolts.

[0024] Next, before passing the wire 3 through the hollow hole 9 in the structural member, each wire holder 11 is fixed near the attachment position to the structural member at a midpoint in the longitudinal direction of the wire 3. By opening and closing the slits 11c by elastically deforming the wire holder 11, the wire holder 11 can be easily attached to a midpoint in the longitudinal direction of the wire 3. At this time, the two wire holders 11 are fixed in a predetermined phase relationship around the longitudinal axis of the wire 3.

[0025] Next, the first cable tie 13 is wound around the cable groove 11d of the wire holder 11 attached to the wire 3, thereby fixing the wire holder 11 so that it cannot rotate around the longitudinal axis of the wire 3. By winding the first cable tie 13 around the cable groove 11d, it becomes difficult for the first cable tie 13 to come off the wire holder 11. This makes it possible to more reliably maintain the state in which the wire holder 11 is fixed to the wire 3.

[0026] Next, the wire 3 with the two wire holders 11 attached thereto is inserted into the structural member via the hollow hole 9. The wire holder 11 has an outer diameter smaller than the inner diameter of the hollow hole 9 when attached to the wire 3, so that one of the wire holders 11 can be inserted into the structural member via the hollow hole 9 together with the wire 3.

[0027] When one of the wire holders 11 reaches the vicinity of the opening of the hollow hole 9 on the inner wall surface of the structural member, the wire holder 11 is positioned at the attachment position of the wire 3 on the inner wall surface of the structural member using the longitudinal end face of the wire holder 11 or the position of the cable groove 11d as an index.

[0028] Similarly, using the longitudinal end face or cable groove 11d of the other wire holder 11 as an index, the wire holder 11B is positioned at the attachment position of the wire 3 on the outer wall surface of the structural member. Then, the flat surfaces 11b of the two wire holders 11 are placed on the attachment surfaces of the attachment portions 7b of the auxiliary fixing member 7.

[0029] In this case, the position of the plane 11b of the wire holder 11 indicates the phase around the longitudinal axis of the wire 3 attached to the structural member, so that if there is an unintended twist in the wire 3, it can be easily corrected to the correct phase using the plane 11b as an indicator.

[0030] Furthermore, since the mounting surfaces of the filament holder 11 and the mounting portion 7b of the auxiliary fixing member 7 are flat, it is more difficult for the filament holder 11 to rotate around the longitudinal axis of the filament 3 and it is easier for the filament holder 11 to remain on the mounting portion 7b than when one or both of the mounting surfaces are curved.

[0031] When each of the wire holders 11 is placed on the mounting portion 7b of each of the auxiliary fixing members 7 without any unintended twisting of the wire 3, the wiring work for the wire 3 is completed.

[0032] As described above, with the wire body holder 11 and wire body fastener 1 according to this embodiment, by attaching the wire body holder 11 to the wire body 3 outside the structural member, it is possible to easily fix each wire body holder 11 in a desired phase relationship without twisting the wire body 3.

[0033] Furthermore, by using the flat surface 11b provided on a part of the outer circumferential surface of the wire holder 11 as an index indicating the phase around the longitudinal axis of the wire 3, the wire holder 11 can be attached to the attachment position of the structural member without twisting the wire 3. Therefore, the wire 3 can be wired inside the structural member without twisting.

[0034] In the present embodiment, a case where one wire 3 is held by the wire holder 11 has been described as an example. Alternatively, as shown in Fig. 3, a plurality of wires 3 may be held by the wire holder 11. Fig. 3 illustrates a case where four wires 3 are wired.

[0035] 3, when there are multiple wires 3, wire holders 11 are fixed near the respective attachment positions to the structural member at midpoints in the longitudinal direction of the multiple wires 3. In this case, the wires 3 are radially shifted and in close contact with each other, and the wire holders 11 are arranged so as to surround all of the wires 3 at midpoints in the longitudinal direction.

[0036] By bundling the plurality of wire bodies 3 together with the wire body holder 11 before passing them through the hollow hole 9, it is possible to prevent each wire body 3 from being attached to the structural member in a twisted state, and also to prevent the plurality of wire bodies 3 from being attached to the structural member in a tangled state inside the hollow hole 9.

[0037] In this embodiment, the cable groove 11 d is provided in the cable holder 11. As long as it is possible to make it difficult for the first cable tie 13 to come off the cable holder 11, the cable holder 11 may be provided with a hole (first binding member hole) through which the first cable tie 13 passes, instead of the cable groove 11 d.

[0038] In this embodiment, the wire body fastener 1 is provided with a first cable tie 13. If the wire body holder 11 can fasten the wire body 3 so that it cannot rotate around the longitudinal axis thereof by its elastic force and the friction between the inner surface of the wire body holder 11 and the outer surface of the wire body 3, the first cable tie 13 does not need to be used. Also, the wire body holder 11 may be fastened to the wire body 3 by an adhesive.

[0039] Second Embodiment Next, a wire body holder and a wire body fastener according to a second embodiment of the present disclosure will be described. As shown in Figure 4, the wire body fastener 1 according to this embodiment differs from the first embodiment in that it does not include a first cable tie 13. Hereinafter, parts that share the same configuration as the wire body holder 11 and wire body fastener 1 according to the first embodiment will be assigned the same reference numerals and will not be described again.

[0040] The wire fixture 1 includes, instead of the wire holder 11, two wire holders 21 that are detachably attached to the two auxiliary fixing members 7 by snap fitting.

[0041] As shown in Figure 5, each wire holder 21 has four elastically deformable claws (protrusions) 11e that protrude perpendicularly from the flat surface 11b. The four claws 11e are spaced apart in the width and length directions of the flat surface 11b. Using the flat surface 11b and the positions of the claws 11e of the wire holder 21 as indicators, the phase of the wire 3 about its longitudinal axis when attached to the structural member can be determined. The claws 11e also function as attachment position recognition units that indicate the attachment position of the wire 3 in the longitudinal direction on the structural member.

[0042] The wire body holder 21 does not have a cable groove 11d on its outer surface, and is fixed so that it cannot rotate around the longitudinal axis of the wire body 3 by the elastic force of the wire body holder 21 or by an adhesive or the like that bonds the inner surface of the wire body holder 21 to the outer surface of the wire body 3.

[0043] In this embodiment, the auxiliary fixing member 7 has four grooves (recesses) (not shown) on the mounting surface of the mounting portion 7b, into which the claws 11e of the wire holder 21 are detachably fitted.

[0044] The four claws 11e of the wire body holder 21 are fitted into the four grooves on the mounting surface of the auxiliary fixing member 7 by elastic deformation, thereby attaching the wire body holder 21 to the auxiliary fixing member 7. The four claws 11e of the wire body holder 21 are also removed from the four grooves on the mounting surface of the auxiliary fixing member 7 by elastic deformation, thereby removing the wire body holder 21 from the auxiliary fixing member 7.

[0045] The operation of the wire member holder 21 and wire member fastener 1 according to this embodiment configured as described above will be described below. To wire the wire member 3 to a structural member using the wire member holder 21 and wire member fastener 1 according to this embodiment, before passing the wire member 3 through the hollow hole 9, each wire member holder 21 is fixed non-rotatably by its elastic force or adhesive near the attachment position to the structural member at a midpoint in the longitudinal direction of the wire member 3. At this time, the two wire member holders 21 are fixed in a predetermined phase relationship around the longitudinal axis of the wire member 3.

[0046] Next, the wire 3 to which the two wire holders 21 are attached is inserted into the structural member via the hollow hole 9. When one of the wire holders 21 reaches the vicinity of the opening of the hollow hole 9 on the inner wall surface of the structural member, any unintended twisting of the wire 3 is corrected using the flat surface 11b of each wire holder 21 as an index.

[0047] Next, using the longitudinal end faces or claw portions 11e of each wire holder 21 as indicators, each wire holder 21 is positioned at the attachment position of the wire 3 on the inner wall surface and outer wall surface of the structural member. Then, the flat surface 11b of each wire holder 21 is placed on the attachment surface of the attachment portion 7b of each auxiliary fixing member 7.

[0048] Next, the four claws 11e of the wire holder 21 are fitted into the four grooves on the mounting surface of the auxiliary fixing member 7, respectively, to attach the wire holder 21 to the auxiliary fixing member 7 by snap-fitting. This fixes the wire 3 to the structural member. When each wire holder 21 has been attached to each auxiliary fixing member 7 without twisting the wire 3, the wiring work for the wire 3 is complete.

[0049] As explained above, with the wire body holder 21 and wire body fastener 1 according to this embodiment, the wire body holder 21 can be attached to and detached from the auxiliary fixing member 7 by snap-fitting, so that the wire body holder 21 can be easily attached to the auxiliary fixing member 7 in a unique position. Furthermore, compared to when the attachment surfaces of the wire body holder 21 and the auxiliary fixing member 7 are flat, rotation of the wire body holder 21 around the longitudinal axis of the wire 3 can be more reliably prevented.

[0050] Furthermore, by using the flat surface 11b and the claw portion 11e provided on part of the outer surface of the wire body holder 21 as indicators indicating the phase around the longitudinal axis of the wire body 3, the wire body holder 21 can be attached to the attachment position of the structural member without twisting the wire body 3.

[0051] In this embodiment, the wire body holder 21 has a claw portion 11e, and the auxiliary fixing member 7 has a groove portion. The attachment surfaces of the wire body holder 21 and the auxiliary fixing member 7 may have complementary shapes that fix the rotation of the wire body holder 21 about the longitudinal axis, for example, the wire body holder 21 may have a groove portion, while the auxiliary fixing member 7 may have a claw portion 11e. Furthermore, the configuration is not limited to a groove portion and a claw portion 11e, and may be a recess portion and a protrusion portion that is detachably fitted into the recess portion.

[0052] Third Embodiment Next, a wire body holder and a wire body fastener according to a third embodiment of the present disclosure will be described. As shown in Figure 6, the wire body fastener 1 according to this embodiment differs from the first and second embodiments in that it includes a mutual rotation prevention member 25 that maintains a predetermined phase relationship between the wire body holders 21 about the longitudinal axis of the wire 3. Hereinafter, parts that share the same configuration as the wire body holders 11, 21 and wire body fastener 1 according to the first and second embodiments will be assigned the same reference numerals, and their description will be omitted.

[0053] The mutual rotation prevention member 25 is made of a flexible and rigid material such as metal, resin, rubber, etc. The mutual rotation prevention member 15 is formed in the shape of a long, thin plate that is hung between the two wire holders 21 along the longitudinal axis of the wire 3.

[0054] The mutual rotation prevention member 25 has, for example, protrusions or holes (not shown) at both longitudinal ends of one surface. The wire holder 21 has holes or protrusions, which have shapes complementary to the protrusions or holes of the mutual rotation prevention member 25, on its outer peripheral surface on the radially opposite side from the flat surface 11 b.

[0055] The protrusions or holes at both ends of the mutual rotation prevention member 25 are fitted into the holes or protrusions of the two wire body holders 21 fixed to the wire body 3, so that the mutual rotation prevention member 25 is detachably attached to each of the wire body holders 21 in a state of being suspended across the two wire body holders 21. Furthermore, the mutual rotation prevention member 25 can be removed from each of the wire body holders 21 by disengaging the protrusions or holes of the mutual rotation prevention member 25 from the holes or protrusions of the two wire body holders 21.

[0056] The following describes the operation of the thus configured wire member holder 21 and wire member fastener 1. To wire the wire member 3 to a structural member using the wire member holder 21 and wire member fastener 1 according to this embodiment, before passing the wire member 3 through the hollow hole 9, the wire member holder 21 is fixed by its elastic force or adhesive in a predetermined phase relationship so as not to rotate, near the attachment position to the structural member at a midpoint in the longitudinal direction of the wire member 3.

[0057] Next, the protrusions or holes at both ends of the mutual rotation prevention member 25 are fitted into the holes or protrusions on the outer surface of each wire body holder 21, so that the mutual rotation prevention member 25 is attached to each wire body holder 21 in a state where it is suspended across the two wire body holders 21.

[0058] Next, the wire 3 to which the two wire holders 21 and the mutual rotation prevention members 25 are attached is inserted into the structural member via the hollow hole 9. When one of the wire holders 21 reaches the vicinity of the opening of the hollow hole 9 on the inner wall surface of the structural member, the positions of the longitudinal end faces of each wire holder 21 are used as indicators to position each wire holder 21 at the attachment position of the wire 3 on the inner and outer wall surfaces of the structural member.

[0059] Then, after the flat surface 11b of each wire member holder 21 is placed on the mounting surface of the mounting portion 7b of each auxiliary fixing member 7, each wire member holder 21 is attached to the auxiliary fixing member 7 by snap fitting. Once each wire member holder 21 has been attached to each auxiliary fixing member 7, the mutual rotation prevention members 25 are removed from both wire member holders 21 and then pulled out from the hollow hole 9. This completes the wiring work for the wire 3.

[0060] As described above, with the wire body holder 21 and wire body fixing device 1 according to this embodiment, by attaching mutual rotation prevention members 25 to the two wire body holders 21 and inserting one of the wire body holders 21 together with the wire body 3 into a structural member, it is possible to prevent the wire body 3 from twisting when passing through the hollow hole 9.

[0061] In this embodiment, the case where the mutual rotation prevention member 25 is applied to the wire body holder 21 of the second embodiment has been described as an example. Alternatively, the mutual rotation prevention member 25 may be applied to the wire body holder 11 of the first embodiment.

[0062] In this case, the mutual rotation prevention member 25 may be detachably attached to each of the wire body holders 11 with the first cable tie 13 wound around each of the wire body holders 11. For example, the cable tie 13 may be wound around each of the wire body holders 11 at a position shifted in the longitudinal direction of the wire body holder 11 from the attachment position of the mutual rotation prevention member 25 on the wire body holder 11.

[0063] In this embodiment, protrusions or holes are provided on both ends of the mutual rotation prevention member 25 and on the outer circumferential surfaces of the two wire body holders 21. The attachment means is not limited to this, as long as it allows the mutual rotation prevention member 25 to be detachably attached to the two wire body holders 21. For example, a through hole may be provided in the mutual rotation prevention member 25 and a tapped hole may be provided in the wire body holder 21, and the mutual rotation prevention member 25 may be attached to the wire body holder 21 by bolt fastening. Alternatively, the mutual rotation prevention member 25 may be attached to the wire body holder 21 by a hook-and-loop fastener such as Velcro (registered trademark).

[0064] In this embodiment, after each wire holder 21 of the wire 3 is attached to the auxiliary fixing member 7, the mutual rotation prevention member 25 is pulled out of the hollow hole 9. If the structural member is a movable part that moves relative to the fixed part, the mutual rotation prevention member 25 needs to be pulled out of the hollow hole 9. On the other hand, if the structural member is a fixed part that is installed on the floor surface, the mutual rotation prevention member 25 may be left attached to the wire holder 21 without being pulled out. In this case, the mutual rotation prevention member and the two wire holders may be configured integrally.

[0065] The first to third embodiments can be modified as follows. In the above embodiments, cylindrical wire holders 11 and 21 having slits 11c have been described as examples. Instead of this, as shown in FIG. 7, for example, a wire holder 31 may be employed that is made up of a pair of semi-cylindrical bodies 33 and 35 formed by dividing a single cylindrical member into two halves along a plane including the central axis.

[0066] In this case, a plurality of grooves 33a may be provided on the circumferential outer edge of one semi-cylinder 33, and a plurality of claws 35a may be provided on the circumferential outer edge of the other semi-cylinder 35. The claws 35a are removably fitted into the grooves 33a by elastic deformation. The semi-cylinders 33, 35 may be connected to each other by snap-fitting with the filament 3 sandwiched radially between them. In this case, at least a portion of the inner surface of each semi-cylinder 33, 35 in the circumferential direction serves as the contact surface 11f.

[0067] In this modification, a flat surface 11b may be provided on the outer peripheral surface of one of the semi-cylinders 33. Furthermore, a claw portion 11e or a groove portion for fixing to the auxiliary fixing member 7 by snap-fitting may be provided on the flat surface 11b.

[0068] 8, a semi-cylindrical filament holder 41 may be used instead of the filament holders 11, 21, and 31. The semi-cylindrical filament holder 41 has a circumferential portion cut out in the longitudinal direction from one end to the other end. In this case, at least a portion of the circumferential surface of the inner surface of the filament holder 41 serves as the contact surface 11f.

[0069] In this case, the wire holder 41 may have a flat surface 11b extending in the longitudinal direction at the circumferential center of its outer circumferential surface. The wire holder 41 may also have a plurality of cable grooves 11d (grooves for the first bundling member, grooves for the second bundling member) on its outer circumferential surface, extending in the circumferential direction on either side of the flat surface 11b. In the example shown in Fig. 8, three cable grooves 11d are provided on the outer circumferential surface of the wire holder 41.

[0070] 9, with the wire 3 housed on the inner circumferential surface of the wire holder 41, the wire holder 41 may be fastened to the wire 3 by, for example, a single first cable tie 13 arranged along the cable groove 11d of the wire holder 41. In the example shown in FIG. 9, the entire circumferential area of ​​the inner surface of the wire holder 41 forms a contact surface 11f.

[0071] Furthermore, the wire 3 and the wire holder 41 may be fastened together to the attachment portion 7b of the auxiliary fixing member 7 by two second cable ties (second bundling members) 43 arranged along other cable grooves 11d of the wire holder 41. The attachment portion 7b of the auxiliary fixing member 7 may be provided with notches (second bundling member notches) 7d through which the second cable ties 43 fastened to the wire 3 and the wire holder 41 pass.

[0072] In this modification, instead of the notch 7d, a hole (second binding member hole) through which the second cable tie 43 is passed may be provided in the auxiliary fixing member 7. In Fig. 9, reference numeral 7e denotes a bolt hole for fastening the fixing portion 7a of the auxiliary fixing member 7 to a structural member with a bolt.

[0073] Fourth Embodiment Next, a wire body holder and a wire body fastener according to a fourth embodiment of the present disclosure will be described. As shown in Figures 10 and 11 , the wire body fastener 1 according to this embodiment differs from the first to third embodiments in that, instead of wire body holders 11, 21, 31, and 41, it includes a wire body holder 51 that can be separated into multiple segments 53, 55, and 57 that are individually fastened to two or more wire bodies 3. Hereinafter, parts that share the same configuration as the wire body holders 11, 21, 31, and 41 and the wire body fastener 1 according to the first to third embodiments will be assigned the same reference numerals, and descriptions thereof will be omitted.

[0074] The two wire member holders 51 have a cylindrical shape and are made of an elastically deformable material such as resin or rubber. In the example shown in Figures 10 and 11, each wire member holder 51 is formed so as to be separable in the circumferential direction into three segments 53, 55, and 57. The segments 53, 55, and 57 are separated at different angles around an axis parallel to the central axis of the wire member holder 51.

[0075] Each of the divided bodies 53, 55, 57 has a through hole (filament hole) 53a, 55a, 57a extending in the longitudinal direction so that one of the filaments 3 can pass through. Each of the divided bodies 53, 55, 57 also has a slit (not shown) extending in the longitudinal direction from one end to the other end.

[0076] The slits extend from the outer surfaces of the segments 53, 55, and 57 to the inner peripheral surfaces of the through-holes 53 a, 55 a, and 57 a of the segments 53, 55, and 57. The slits are opened and closed by elastically deforming the segments 53, 55, and 57, so that the filament 3 can be accommodated at a midpoint in the longitudinal direction in the through-holes 53 a, 55 a, and 57 a of the segments 53, 55, and 57.

[0077] At least one of the divided bodies 53, 55, and 57 is provided with a positional relationship recognition unit that indicates the positional relationship of each of the divided bodies 53, 55, and 57 when the wire holder 51 is assembled. For example, the divided body 53 may have a flat surface 11b on its outer circumferential surface, and the flat surface 11b may function as the positional relationship recognition unit. The positional relationships of the divided bodies 54 and 55 with respect to the divided body 53 are each determined in advance.

[0078] By combining the three divided bodies 53, 55, 57 with each other while being individually fixed to the respective filament bodies 3, the three filament bodies 3 are held together by the filament body holder 51 while being arranged in parallel with their positions shifted in the radial direction.

[0079] The segments 53, 55, and 57 may be fixed to each other by bonding the connecting surfaces of adjacent segments 53, 55, and 57 with an adhesive. Alternatively, the three segments 53, 55, and 57 may be bundled together with a cable tie. Alternatively, holes or protrusions may be provided on the connecting surfaces of adjacent segments 53, 55, and 57, and the connecting surfaces of adjacent segments 53, 55, and 57 may be fixed to each other by fitting the holes and protrusions together.

[0080] The following describes the operation of the wire holder 51 and wire fixture 1 configured as described above. To wire a plurality of wires 3 to a structural member using the wire holder 51 and wire fixture 1 according to this embodiment, before passing the wires 3 through the hollow hole 9, the segments 53, 55, and 57 of the two wire holders 51 are individually fixed by their elastic force or adhesive near the attachment position to the structural member at a midpoint in the longitudinal direction of each wire 3. At this time, the segments 53, 55, and 57 are fixed in a predetermined phase relationship around the longitudinal axis of each wire 3.

[0081] Next, the filament 3 to which each divided body 53, 55, 57 is attached is inserted one by one into the structural member via the hollow hole 9. When all of the divided bodies 53, 55, 57 of one filament holder 51 have reached the vicinity of the opening of the hollow hole 9 on the inner wall surface of the structural member, the divided bodies 53, 55, 57 are fixed to each other with a fixing means such as an adhesive, thereby assembling the filament holder 51.

[0082] At this time, the divided bodies 53, 55, and 57 are arranged in a predetermined positional relationship using the flat surface 11b of each divided body 53 as an index, with the three filaments 3 free from unintended twists and tangles.

[0083] Next, using the longitudinal end faces of each wire holder 51 as indicators, each wire holder 51 is positioned at the attachment position of the wire 3 on the inner wall surface and outer wall surface of the structural member. Then, the flat surface 11b of each wire holder 51 is placed on the attachment surface of the attachment portion 7b of each auxiliary fixing member 7. Once the wire holder 51 is attached to each auxiliary fixing member 7 without any twisting of the wire 3, the wiring work for the wire 3 is complete.

[0084] As described above, with the filament holder 51 and filament fixing device 1 according to this embodiment, when a plurality of filaments 3 are held by the filament holder 51, the filament holder 51 can be divided into segments 53, 55, 57 for each filament 3, making it easier to pass the filament through the hollow hole 9 of the structural member.

[0085] In this case, the positional relationship of each divided body 53, 55, 57 when the wire holder 51 is assembled can be determined by using the flat surface 11b of the divided body 53 as an index, so that the multiple wires 3 can be easily wired in a predetermined positional relationship.

[0086] In this embodiment, the filament holder 51 is formed so as to be separable into three divided bodies 53, 55, and 57, but it may be formed so as to be separable into the same number of divided bodies 53, 55, and 57 as the number of filaments 3.

[0087] In this embodiment, the filament 3 is inserted one by one into the hollow hole 9. If the outer diameter of the filament holder 51 is smaller than the inner diameter of the hollow hole 9, the filament holder 51 may be inserted into the hollow hole 9 in a constructed state.

[0088] Furthermore, in this embodiment, the flat surface 11b is used as the positional relationship recognition portion, but the positional relationship recognition portion may be anything that indicates the positional relationship of each of the divided bodies 53, 55, and 57 in the assembled state of the filament holder 51. For example, a mark such as a symbol or letter may be attached to at least one of the divided bodies 53, 55, and 57, and the mark may serve as the positional relationship recognition portion. Furthermore, by color-coding the divided bodies 53, 55, and 57, the colors of the divided bodies 53, 55, and 57 themselves may serve as the positional relationship recognition portion.

[0089] Furthermore, when holes or protrusions are provided on each connecting surface as means for fixing the segments 53, 55, and 57, the holes and protrusions may function as positional relationship recognition units. For example, segment 53 may be provided with a hole on each connecting surface with the other two segments 55 and 57, segment 55 may be provided with a protrusion on the connecting surface with segment 53, and a hole on the connecting surface with segment 57, and segment 57 may be provided with a protrusion on each connecting surface with segments 53 and 55.

[0090] In this embodiment, the segments 53, 55, and 57 have through holes 53 a, 55 a, and 57 a, respectively. Alternatively, the segments 53, 55, and 57 may be provided with notches (notches for the filament) for attaching the segments 53, 55, and 57 to the filament 3 in a state where the notches surround the filament 3.

[0091] The first to fourth embodiments can be modified as follows. In the above embodiments, the flat surface 11b, or the claw portion 11e and groove portion have been described as examples of the phase recognition portion. Instead of this, the phase recognition portion may be a mark such as a symbol or letter indicating the phase of the wire body 3 around the longitudinal axis, attached to a visible position on the wire body holder 11, 21, 31, 41, or 51. Furthermore, the phase recognition portion may be a color-coded circumferential surface of the wire body holder 11, 21, 31, 41, or 51 so that the phase of the wire body 3 around the longitudinal axis can be recognized.

[0092] Alternatively, the phase recognition portion may be a recess or protrusion on the outer peripheral surface of the wire body holder 11, 21, 31, 41, or 51 that indicates the phase around the longitudinal axis of the wire body 3. Alternatively, the phase recognition portion may be a feature that can recognize the phase around the longitudinal axis of the wire body 3 in the shape of the outer peripheral surface of the wire body holder 11, 21, 31, 41, or 51 itself.

[0093] Furthermore, in each of the above embodiments, the wire body fixing device 1 is provided with the auxiliary fixing member 7, but the wire body holder 11 may be fixed directly to the inner wall surface and the outer wall surface of the structural member without providing the auxiliary fixing member 7.

[0094] The filament 3 may also have one or more lines extending along the longitudinal axis on the outer circumferential surface thereof. The lines attached to the filament 3 make it easier to determine whether the filament 3 is twisted.

[0095] In each of the above embodiments, the outer diameter of each of the two wire body holders 11 is smaller than the inner diameter of the hollow hole 9. The other wire body holder 11, 21, 31, 41, 51 that is not inserted into the hollow hole 9 may have an outer diameter larger than the inner diameter of the hollow hole 9.

[0096] In the above embodiments, the wire member holders 11 and 21 have been described as having slits, but the wire member holders may be formed in a cylindrical shape without slits 11c. In this case, the wire member 3 may be inserted into the through-hole 11a of the wire member holder 11 from the end in the longitudinal direction. Furthermore, the wire member fixing device 1 may include two or more wire member holders.

[0097] According to at least one of the embodiments described above, before the wire 3 is passed through the hollow hole 9 of the structural member, the wire holders 11, 21, 31, 41, and 51 are fixed to the wire 3 at a midpoint in the longitudinal direction thereof near the attachment position to the structural member. Therefore, the wire holders 11, 21, 31, 41, and 51 can be fixed to one or more wires 3 without twisting or tangling.

[0098] Furthermore, the phase around the longitudinal axis of the wire 3 to be attached to the structural member can be determined by the phase recognition portion such as the flat surface 11b provided on the wire holder 11, 21, 31, 41, 51, so that the wire holder 11, 21, 31, 41, 51 can be attached to the attachment position of the structural member without twisting or tangling the wire 3. Therefore, one or more wires 3 can be wired inside the structural member without twisting or tangling.

[0099] In the above-described embodiments, the case where the filament 3 is wired inside the structural member via the hollow hole 9 using the filament holder 11, 21, 31, 41, 51 has been described as an example. However, instead of this, the filament 3 may be wired to the wall of the structural member without passing through the hollow hole 9.

[0100] In this case, too, the phase around the longitudinal axis of the wire 3 attached to the structural member can be determined from the position of the flat surface 11b of the wire holder 11, 21, 31, 41, 51, so if the wire 3 is unintentionally twisted, the phase can be easily corrected to the correct one using the flat surface 11b as an index. Therefore, even if the appearance of the wire 3 is not distinctive around the longitudinal axis, the wire 3 can be easily wired to the wall of the structural member without being twisted. If the wire does not pass through the hollow hole 9, the wire holder 11 does not need to have an outer diameter smaller than the inner diameter of the hollow hole 9.
