  However, when such a hollow plate material starts burning, air may be supplied to the burning portion through the space in the hollow plate material.

  Then, an object of this invention is to reduce more the speed which spreads in the electric wire module containing the protection member formed with the hollow plate material.

  The electric wire module according to the first aspect covers at least a part of the electric wire or the electric wire bundle and the electric wire or the electric wire bundle in the circumferential direction, and is disposed between the plurality of plate-like portions and the plurality of plate-like portions. A protection member formed of a hollow plate material including an interposition portion that forms a hollow space between the plurality of plate-like portions, and the hollow plate material is configured to partition the hollow space and the outside. It includes a joined portion in which at least a part of the outer peripheral edge of the plate-like portion is joined together.

  The electric wire module which concerns on a 2nd aspect is an aspect of the electric wire module which concerns on a 1st aspect. In the electric wire module according to the second aspect, the protection member is formed by the hollow plate member including the interposition portion that forms a plurality of elongated hollow spaces in parallel in the first direction between the plurality of plate portions. And the said junction part has joined at least one of the both sides in the 2nd direction which is the extension direction of the said hollow space.

  The electric wire module which concerns on a 3rd aspect is an aspect of the electric wire module which concerns on a 2nd aspect. In the electric wire module which concerns on a 3rd aspect, the said junction part has joined the both sides in said 2nd direction.

  The electric wire module according to the fourth aspect is an aspect of the electric wire module according to any one of the first aspect to the third aspect. In the electric wire module which concerns on a 4th aspect, the said hollow board material contains the said junction part which joins the said outer peripheral edge parts of these plate-shaped parts.

  The electric wire module according to the fifth aspect is an aspect of the electric wire module according to any one of the first aspect to the fourth aspect. In the electric wire module according to the fifth aspect, the plurality of plate portions are other than the electric wire side plate portion and the electric wire side plate portion that are arranged closest to the electric wire or the electric wire bundle among the plurality of plate portions. The joint portion includes the outer peripheral edge portion of the other plate-shaped portion and the outer peripheral edge portion of the other plate-shaped portion in a state where the outer peripheral edge portion of the other plate-shaped portion is inclined toward the outer peripheral edge portion side of the wire-side plate-shaped portion. At least a part of the outer peripheral edge portion of the wire side plate-like portion is joined.

  The electric wire module according to the sixth aspect is an aspect of the electric wire module according to any one of the first aspect to the fifth aspect. In the electric wire module which concerns on a 6th aspect, the said protection member is formed in the strip | belt shape in alignment with the longitudinal direction of the said electric wire or electric wire bundle, and the said protection member is a lamination | stacking direction of a wide part and these several plate-shaped parts.

  In each of the above aspects, the electric wire module includes a joint portion in which at least some of the outer peripheral edge portions of the plurality of plate-like portions are joined so as to partition the hollow space from the outside. That is, the outside and the hollow space are partitioned by the joint portion in a state where the hollow space exists in the hollow plate material. This makes it difficult for air to flow through the hollow plate. For this reason, even if a hollow board material starts combustion, it becomes difficult to supply air through the inside of a hollow board material with respect to the combustion part. Thereby, the speed which spreads can be reduced more.

  In the second aspect, the protective member is formed of a hollow plate material including a plurality of elongated hollow spaces formed in parallel in the first direction. In this case, air easily flows in the extending direction of the intermediate space. Here, the joining part joins at least one of the both sides in the second direction which is the extending direction of the hollow space. For this reason, in the 2nd mode, it becomes difficult for air to flow in the extension direction of hollow space, and the speed which spreads can be reduced effectively.

  Moreover, in the 3rd aspect, since the junction part has joined the both sides in the 2nd direction which is the extension direction of hollow space, it can make it more difficult to flow the air in a hollow plate material more reliably. Thereby, the speed which spreads more reliably can be reduced.

  Further, in the fourth aspect, the hollow plate material includes a joining portion that joins the outer peripheral edge portions of the plurality of plate-like portions, so that the air in the hollow plate material can be made difficult to flow, and the speed at which the flame spreads is reduced.

And the joining part is a state where the outer peripheral edge of the other plate-shaped portion is inclined toward the outer peripheral edge of the electric wire-side plate-like portion, and At least a part is joined. In this case, at the time of tape winding work for integrating the electric wire or the electric wire bundle and the protective member, the load applied to the portion of the tape that contacts the protective member can be reduced, and the tape for integrating the electric wire bundle and the protective member can be reduced. Durability can be improved.

  In the sixth aspect, the protection member is formed in a belt shape along the longitudinal direction of the electric wire or the electric wire bundle, and includes a wide portion and a narrow portion. In this case, by performing a tape winding operation for fixing the electric wire or the electric wire bundle and the protective member at the narrow portion of the protective member, the fixed state between the electric wire or the electric wire bundle made by tape winding and the protective member is further improved. It can be stable.

  In the seventh aspect, the protective member is formed by bending the hollow plate material on which the joint portion is formed so as to cover the electric wire or the electric wire bundle from at least three sides. In this case, the protection performance of the electric wire or electric wire bundle is improved.

  Hereinafter, embodiments will be described with reference to the accompanying drawings. The following embodiment is an example embodying the present invention, and is not an example of limiting the technical scope of the present invention.

<First Embodiment>
The electric wire module 100 according to the first embodiment will be described with reference to FIGS. The electric wire module 100 includes an electric wire bundle 1 (or electric wires 11) and a protective member 3 formed by the hollow plate material 2. The electric wire module 100 constitutes a part of a wire harness mounted on a vehicle such as an automobile, for example. In the present embodiment, a case where the electric wire module 100 includes the electric wire bundle 1 including the plurality of electric wires 11 is shown, and the case where the electric wire module 100 includes the electric wire bundle 1 will be described below. However, it is also conceivable that the electric wire module 100 includes one electric wire 11 instead of the electric wire bundle 1.

  FIG. 1 is a partially cutaway perspective view of the electric wire module 100. FIG. 2 is a plan view of the electric wire module 100. FIG. 3 is a bottom view of the electric wire module 100. 2 and 3 are views of the electric wire module 100 as viewed from the opposite side. FIG. 4 is a side view of the electric wire module 100. In FIG. 4, the vicinity of the end portion of the protection member 3 in the electric wire module 100 is mainly shown, and an intermediate portion of the electric wire module 100 is omitted. Moreover, in FIGS. 2-4, the electric wire bundle 1 is simplified and shown. 5 and 6 are cross-sectional views of the electric wire module 100. FIG. FIG. 5 is a cross-sectional view taken along the plane II-II in FIG. FIG. 6 is a cross-sectional view in the III-III plane of FIG.

<Wire module: Wire bundle>
The wire bundle 1 is formed by bundling a plurality of wires 11. The electric wire 11 is considered to be an insulated wire including, for example, a core wire that is a conductor and an insulating coating that covers the periphery of the core wire. In addition, it is possible that a core wire is a member which has metals, such as copper or aluminum, as a main component. The insulating coating may be a synthetic resin member mainly composed of polyethylene or vinyl chloride.

  In this embodiment, as FIG. 1-4 shows, the wire bundle 1 is arrange | positioned along a linear path | route. The wire bundle 1 is disposed in a path along the main surface of the plate-like mating member 9. In FIG. 1, the counterpart member 9 is indicated by a virtual line (two-dot chain line). The counterpart member 9 may be, for example, a metal panel that constitutes a vehicle body.

  In the electric wire module 100, a part of the electric wire bundle 1 in the circumferential direction is covered with the protection member 3. Therefore, by arranging the protective member 3 between the mating member 9 and the wire bundle 1, the wire bundle 1 is suppressed from contacting the mating member 9.

  Moreover, in this embodiment, the case where the wire bundle 1 is united with the protection member 3 with the tape 7 is shown. For example, it is conceivable that the tape 7 is wound so as to cover the two bundles together with the wire bundle 1 and the protective member 3 inside.

<Wire module: protection member>
In the electric wire module 100, the protection member 3 covers at least a part of the electric wire bundle 1 in the circumferential direction. In the present embodiment, as shown in FIG. 1, a part of the wire bundle 1 in the circumferential direction is covered with a protective member 3 that supports the wire bundle 1 from one side. That is, the protection member 3 covers a part of the wire bundle 1 on the mating member 9 side and is disposed between the mating member 9 and the wire bundle 1. In the electric wire module 100, the protection member 3 is formed by a hollow plate material 2 including a plurality of plate-like portions 21 and intervening portions 22. The hollow plate member 2 includes a plurality of plate-like portions 21 and an intervening portion 22 disposed between the plurality of plate-like portions 21.

  In the present embodiment, the protection member 3 is formed in a belt shape along the longitudinal direction of the wire bundle 1. Here, the wire bundle 1 is disposed in a linear path as shown in FIG. For this reason, in this embodiment, the protection member 3 is formed in the strip | belt shape in alignment with linear form. In addition, the case where the electric wire bundle 1 is arrange | positioned by the curved path | route is also considered. In this case, it is considered that the protective member 3 is formed in a belt shape along the curved path of the wire bundle 1 or includes a linearly formed portion and a connecting portion that connects them in a bendable manner. It is done.

  In this embodiment, the case where the hollow plate member 2 includes two plate-like portions 21 and an intervening portion 22 disposed between the two plate-like portions 21 is shown. Hereinafter, a case where the plurality of plate-like portions 21 are two plate-like portions 21 will be described. A case where the hollow plate material includes three or more plate-like portions is also conceivable. In this case, it is preferable that an interposition part is provided between each plate-like part. If the interposition part is provided between each plate-shaped part, it will become possible to improve the intensity | strength of a hollow board material more.

  In the present embodiment, the hollow plate member 2 includes a plurality of interposition portions 22 interposed in parallel between the two plate-like portions 21. The plurality of intervening portions 22 are arranged in parallel between the two plate-like portions 21 with an interval therebetween. Each interposed portion 22 is formed in an elongated plate shape, and is disposed in a vertical posture with respect to the two plate-like portions 21. Then, one side portion of each interposition portion 22 is connected to one plate-like portion 21, and the other side portion is connected to another one plate-like portion 21. As a result, the two plate-like portions 21 and the plurality of intervening portions 22 are integrally connected so as to exhibit a ladder-like cross section in a plane orthogonal to the extending direction of the intervening portions 22.

  The plurality of intervening portions 22 form a plurality of elongated hollow spaces 20 in parallel in the first direction between two plate-like portions 21. The first direction is a direction orthogonal to the extending direction of the elongated hollow space 20, and is also a direction orthogonal to the thickness direction that is the stacking direction of a plurality (two in the present embodiment) of the plate-like portions 21. is there. Hereinafter, the extending direction of the hollow space 20 will be referred to as a second direction.

  Each hollow space 20 is surrounded by two intervening portions 22 and two adjacent intervening portions 22. For this reason, in the hollow space 20, the cross-sectional shape orthogonal to the second direction has a square shape.

  It is conceivable that the hollow plate member 2 is a member formed of, for example, a resin material. For example, the case where the hollow plate material 2 is formed of a plastic corrugated board made of a resin material such as polypropylene can be considered. In the case of forming the hollow plate 2, for example, the hollow plate 2 can be continuously produced by an extrusion molding apparatus that extrudes resin from the extrusion hole corresponding to the ladder-shaped cross section. Can be easily manufactured at low cost. In addition, the interposition part 22 may be connected with the plate-shaped part 21 with the adhesive agent or welding.

  According to such a hollow plate material 2, a plurality (two in the present embodiment) of plate-like portions 21 are connected by the intervening portions 22 with a space therebetween, and thus are difficult to bend. Further, since the intervening portion 22 is interposed between the plate-like portions 21, the hollow plate material 2 is also reinforced by the intervening portion 22 so that it is difficult to bend and dent. In particular, in the present embodiment, the hollow plate 2 can be made difficult to bend in the second direction of the hollow space 20.

  Therefore, the protective member 3 formed by bending the hollow plate member 2 can sufficiently protect the wire bundle 1 and can sufficiently restrict the path. In addition, since a hollow structure is formed between the two plate-like portions 21 of the hollow plate member 2, the weight can be reduced and the material cost can be reduced accordingly.

  And the hollow plate material 2 used for the protection member 3 of the electric wire module 100 is at least the outer peripheral edge portion of the plural (two in this embodiment) plate-like portions 21 so as to partition the hollow space 20 and the outside. It includes a joint part 23 that is partly joined together.

  For example, a case where the joining portion 23 joins at least one of both sides in the second direction of the hollow space 20 can be considered. In addition, this embodiment is an example in case the junction part 23 has joined the both sides in the 2nd direction of the hollow space 20. FIG. That is, in the present embodiment, both ends of the two plate-like portions 21 in the second direction are joined to each other. For this reason, the hollow space 20 is sealed, and the hollow space 20 and the outside are separated by the joint portion 23.

  In addition, the joint portion 23 joins both sides of a plurality (two in this embodiment) of the plate-like portions 21 in the first direction in which the plurality of hollow spaces 20 are arranged. In this case, it is conceivable that the joining portion 23 joins a region that does not include the intervening portion 22 in the plate-like portion 21 or joins the outer peripheral edge portions of the plate-like portion 21 together with the intervening portion 22.

  As described above, in this embodiment, both sides of the two plate-like portions 21 are joined by the joining portion 23 in the first direction and the second direction. Therefore, in this embodiment, it can be said that the hollow plate material 2 includes a joint portion 23 that joins the outer peripheral edge portions of a plurality (two in the present embodiment) of the plate-like portions 21. In this case, the hollow plate member 2 is provided with a joint portion 23 so as to collectively surround a plurality of hollow spaces 20 formed in the hollow plate member 2, and the hollow space 20 of the hollow plate member 2 and the outside are joined to each other. 23.

  In the present embodiment, the protection member 3 includes a wide portion 31 and a narrow portion 32. The wide portion 31 is a portion whose dimension in the width direction orthogonal to the longitudinal direction of the wire bundle 1 (or the electric wire 11) and the thickness direction is larger than that of the narrow portion 32. Moreover, the narrow part 32 is a part formed so that a dimension may become smaller than the wide part 31 in the said width direction. The narrow portion 32 is adjacent to the wide portion 31 in the longitudinal direction of the wire bundle 1 (or the electric wire 11). In FIG. 1, for convenience, only the region of the wide portion 31 of the protection member 3 is shown.

  In the present embodiment, the protective member 3 is provided so that the width direction orthogonal to the longitudinal direction of the wire bundle 1 matches the first direction of the hollow plate 2. However, a case where the width direction orthogonal to the longitudinal direction of the wire bundle 1 in the protection member 3 and the first direction of the hollow plate member 2 do not match is also conceivable. For example, the case where the width direction of the protection member 3 and the first direction of the hollow plate member 2 are orthogonal to each other, that is, the case where the width direction of the protection member 3 and the second direction of the hollow plate member 2 coincide.

  In addition, this embodiment is an example in which the protection member 3 includes two wide portions 31 and three narrow portions 32 as shown in FIG. The protection member 3 has narrow portions 32 at both ends in the longitudinal direction of the wire bundle 1. The two wide portions 31 are adjacent to the narrow portions 32 at both ends, respectively, and the two wide portions 31 are connected to one narrow portion 32. That is, in the present embodiment, the protective member 3 includes the narrow portion 32, the wide portion 31, the narrow portion 32, the wide portion 31, and the wide portion 31 in a form formed side by side with the narrow portion 32 in order from the end. A plurality of narrow portions 32 are included.

  In the present embodiment, the narrow portion 32 is a portion around which the tape 7 in the protection member 3 is wound. For this reason, as shown in FIG. 6, in the electric wire module 100 of the present embodiment, the tape 7 is wound so as to collectively cover the electric wire bundle 1 and the narrow portion 32 of the protective member 3, thereby 1 and the protective member 3 are integrated. In this case, in the state where the tape 7 is wound, the gap formed between the narrow portion 32 and the wire bundle 1 can be further reduced.

  On the other hand, in this embodiment, the wide part 31 covers the comparatively wide area | region in the circumferential direction of the wire bundle 1, as FIG. 5 shows. That is, the wide portion 31 is a portion suitable for protecting the wire bundle 1. As shown in FIG. 2, it is conceivable that the protective member 3 is provided so that the region of the wide portion 31 is larger than the region of the narrow portion 32 in the longitudinal direction.

  Moreover, in the electric wire module 100 of this embodiment, the junction part 23 is provided in the state inclined to the one side of the some plate-shaped parts 21. FIG. Hereinafter, for the sake of explanation, the plurality of plate-like portions 21 include an electric-wire-side plate-like portion 211 arranged closest to the wire bundle 1 among the plurality of plate-like portions 21 and other plate-like portions 212 other than the wire-side plate-like portion 211. And include. In this case, the plurality of plate-like portions 21 may include one electric wire side plate-like portion 211 and at least one other plate-like portion. In the present embodiment, the case where the plurality of plate-like portions 21 are two plate-like portions 21 is shown. Therefore, in the present embodiment, the two plate-like portions 21 include one electric wire side plate-like portion 211 and one other plate-like portion 212. Hereinafter, the two plate-like portions 21 will be referred to as distinguished from the wire-side plate-like portion 211 and the other plate-like portion 212 as necessary.

  In the present embodiment, as shown in FIGS. 4 to 6, the joining portion 23 is configured so that the outer peripheral edge portion of the other plate-like portion 212 is inclined toward the outer peripheral edge portion side of the electric wire side plate-like portion 211. The outer peripheral edge portion of the wire-like portion 212 and the outer peripheral edge portion of the electric wire side plate-like portion 211 are joined. In addition, as above-mentioned, the junction part 23 can also consider the case where some outer peripheral edge parts of these two plate-shaped parts 21 are joined. Therefore, it can be said that the joining portion 23 joins at least a part of the outer peripheral edge portion of the other plate-like portion 212 and the outer peripheral edge portion of the wire-side plate-like portion 211.

  The joint 23 is formed, for example, by pressing the hollow plate 2 using a mold 6 including an upper mold 61 and a lower mold 62 as shown in FIGS.

  The lower mold 62 includes a flat mold surface 620. In the present embodiment, the hollow plate member 2 in a state before the joining portion 23 is formed is placed on the mold surface 620.

  The upper mold 61 includes a concave mold surface 610. In the present embodiment, the mold surface 610 includes a first portion 611 and a second portion 612 that are portions for pressing one of the two plate-like portions 21 of the hollow plate member 2 against the other.

  The second portion 612 is a portion facing the mold surface 620 of the lower mold 62 with a gap in a state where the upper mold 61 and the lower mold 62 are closest to each other. The distance between the second portion 612 and the mold surface 620 when the upper mold 61 and the lower mold 62 are closest to each other may be the same as or larger than the dimension in the thickness direction of the hollow plate 2. preferable.

  The first portion 611 is a portion that presses one of the two plate-like portions 21 of the hollow plate member 2 against the other, and is provided on both sides of the second portion 612. In the present embodiment, since the outer peripheral edge portions of the two plate-like portions 21 are joined together, it is conceivable that the first portion 611 is provided so as to surround the second portion 612. In this case, the joining part 23 can be provided in the whole outer peripheral part of the two plate-shaped parts 21 by one press operation. However, the case where the 1st part 611 is provided only in the both sides in one direction of the 2nd part 612 is also considered. For example, this is the case where the joint portion 23 is provided by two or more pressing operations, or the joint portion 23 is provided at a part of the outer peripheral edge portions of the two plate-like portions 21.

  In the present embodiment, as shown in FIG. 7, first, the hollow plate member 2 is placed on the mold surface 620 of the lower mold 62. Then, the upper mold 61 and the lower mold 62 are brought close to each other while the mold surface 610 of the upper mold 61 and the mold surface 620 of the lower mold 62 are kept facing each other.

  In the state where the upper mold 61 and the lower mold 62 are closest to each other, as shown in FIG. 8, the first portion 611 of the upper mold 61 is the outer peripheral edge of the two plate-shaped portions 21 of the hollow plate 2. One of the parts is pressed against the other on the lower mold 62 side. As described above, the two plate-like portions 21 are sandwiched and pressed between the first portion 611 of the upper die 61 and the die surface 620 of the lower die 62, so that the outer peripheral edges of the two plate-like portions 21 are obtained. A joint portion 23 that joins the portions is formed.

  At this time, the outer peripheral edge portion of the plate-like portion 21 on the upper mold 61 side of the two plate-like portions 21 is pressed in a state inclined to the outer peripheral edge side of the plate-like portion 21 on the lower mold 62 side. . The mold surface 620 of the lower mold 62 is flat, and the distance between the mold surface 620 of the lower mold 62 and the second portion 612 of the upper mold 61 is the same as the mold surface 620 of the lower mold 62. This is because the distance between the upper mold 61 and the first portion 611 is larger. Accordingly, in the state where the outer peripheral edge portion of the plate-like portion 21 on the upper mold 61 side of the two plate-like portions 21 is inclined toward the outer peripheral edge side of the plate-like portion 21 on the lower mold 62 side, the two plates The outer peripheral edges of the shaped portions 21 are joined together. Thereby, the junction part 23 joined in the state in which the outer peripheral edge part of the one side of the two plate-shaped parts 21 was inclined to the outer peripheral edge part of the other side is provided. That is, when the joining portion 23 is provided by the method described above, the plate-like portion 21 on the upper mold 61 side forms the other plate-like portion 212, and the plate-like portion 21 on the lower mold 62 side becomes the wire-side plate shape. A portion 211 is formed.

  In addition, it is preferable that the 1st part 611 is provided with the heating mechanism, and the outer peripheral edge parts of the two plate-shaped parts 21 are pressed while heating. In this case, it is because the junction part 23 can be provided more reliably. In addition, by pressing the outer peripheral edges of the two plate-like portions 21 with the adhesive provided on the surface of the two plate-like portions 21 facing the other side, the two plate-like portions are bonded by the adhesive. It is also conceivable to make a joint where the outer peripheral edges of 21 are joined together.

  7 and 8, when the joint portion 23 is formed, the mold surface 620 of the lower mold 62 is flat, so that the gap between the wire-side plate-like portion 211 and the joint portion 23 is flat. It is conceivable that no step is formed and the electric wire side plate-like portion 211 and the joint portion 23 are provided on the same plane. More specifically, it is conceivable that the main surface of the electric wire side plate-like portion 211 and the main surface of the joint portion 23 are located on the same plane. In this case, the tape 7 wound around the protective member 3 can be prevented from hitting the protective member 3 at an acute angle.

  Moreover, as FIG. 6 shows, the case where the junction part 23 is deformably formed so that it may fall to the electric wire side plate-shaped part 211 side is also considered. In this case, the tape winding operation can be easily performed by winding the tape 7 in a state in which the joint portion 23 is tilted and deformed toward the wire bundle 1 side. Further, the tape 7 is wound in a state where the joint portion 23 is tilted and deformed toward the wire bundle 1 side, so that the gap between the wire bundle 1 and the protection member 3 is further reduced in the state wound around the tape 7. Can do.

  In the present embodiment, as shown in FIGS. 2 and 3, the protection member 3 includes a wide portion 31 and a narrow portion 32. And the outer peripheral edge parts of the two plate-shaped parts 21 of the hollow plate material 2 constituting the protection member 3 are joined to each other. In this case, for example, it is conceivable that the hollow plate 2 set in the mold 6 is made in a form in which the wide portion 31 and the narrow portion 32 are provided in advance. In this case, it is not necessary to provide a cutting blade for cutting in the mold 6. Further, for example, a cutting blade is provided in the first portion 611 of the upper mold 61, and the cutting work is performed on the hollow plate member 2 by the cutting blade provided in the first portion 611 simultaneously with the pressing operation by the mold 6, thereby completing the protective member 3. It is possible to make it. In this case, the time required for the manufacturing operation can be suppressed.
