Description

The present invention relates to a harness mounting member for mounting a wire harness to a specified mounting location, and a wire harness arrangement structure in which the harness mounting member with the wire harness exterior is mounted to the mounting location.

A wire harness installed in a vehicle or the like is composed of, for example, a first wire harness that electrically connects the battery and electrical devices that are installed as standard, and a second wire harness that connects electrical devices that are added as optional devices to the battery, etc.

As an example of an attachment structure for attaching such a second wire harness to a first wire harness, Patent Document 1 discloses a protector having a male engagement portion and a female engagement portion on the side wall of a hollow protector through which the wire harness passes.

This protector allows the second wire harness to be attached to the first wire harness by engaging the male engagement portion of the protector through which the second wire harness is inserted with the female engagement portion of the protector that protects the first wire harness.

However, with the protector disclosed in Patent Document 1, the same protector must be used to attach the second wire harness to the first wire harness. Also, the second wire harness could not be attached to a desired location other than the protector. Therefore, there was a need for a new harness attachment member that would allow the wire harness to be easily attached to a specified location.

JP 2015-154596 A

In consideration of the above problems, this invention aims to provide a harness mounting member that can mount a wire harness to a mounting location with a simple structure, and a wire harness routing structure in which the harness mounting member to which the wire harness is mounted is attached to a protector through which another wire harness is inserted.

This invention is a harness mounting member for mounting a wire harness to a mounting location formed of a resin sheet material, and is characterized in that it is provided with an exterior body that covers at least a portion of the wire harness, and an insertion protrusion that protrudes from the exterior body in a direction that intersects the longitudinal direction of the wire harness and is inserted into a mounting hole provided at the mounting location, and the exterior body and the insertion protrusion are formed of a resin sheet material.

The present invention also provides a wire harness arrangement structure comprising: a first wire harness arranged in a predetermined arrangement path; a protector into which the first wire harness is inserted; a second wire harness arranged parallel to the first wire harness; and a harness mounting member for mounting the second wire harness to an attachment location of the protector, the harness mounting member being made of a resin sheet material and including an outer casing for covering at least a portion of the second wire harness and an insertion protrusion protruding from the outer casing in a transverse direction intersecting the longitudinal direction of the first wire harness, a mounting hole for inserting the insertion protrusion being provided at the attachment location of the protector, the insertion protrusion of the harness mounting member that has covered at least a portion of the second wire harness along the longitudinal direction of the outer casing being inserted into the mounting hole to attach the harness mounting member to the protector, the insertion protrusions being provided opposite each other on both sides in a width direction perpendicular to the longitudinal direction, and the opposed insertion protrusions being inserted in a state of being overlapped in the mounting hole .

Furthermore, the present invention is characterized in that it is a wire harness arrangement structure comprising: a wire harness arranged in a predetermined wiring path; an attachment member made of a resin sheet material and fixed to a predetermined location in the wiring path; and a harness attachment member for attaching the wire harness to the attachment member, the harness attachment member being made of a resin sheet material and having an exterior body that exteriors at least a part of the wire harness and an insertion protrusion that protrudes from the exterior body in a cross direction that intersects the longitudinal direction of the wire harness, the attachment member being provided with an attachment hole for inserting the insertion protrusion, the insertion protrusion of the harness attachment member that exteriors at least a part of the wire harness along the longitudinal direction is inserted into the attachment hole to attach the harness attachment member to the attachment member fixed to the predetermined location in the wiring path, the insertion protrusions being provided opposite each other on both sides in a width direction perpendicular to the longitudinal direction, and the opposed insertion protrusions being inserted in a state of being overlapped in the attachment hole .

The resin sheet material is not particularly limited as long as it can be bent, and includes both thermoplastic resin sheet materials and thermosetting resin sheet materials. In addition, it is preferable that the resin sheet material is a synthetic resin foam sheet material composed of a synthetic resin foam molded into a foamed or porous shape. This allows the harness attachment member to have excellent flexibility and cushioning properties, and further improves wearability and processability.

The mounting hole is not particularly limited as long as the insertion protrusion can be inserted, and may be provided, for example, in the cover of the protector made of the resin sheet material or on the side of the protector. The mounting hole may also be provided in a member made of the resin sheet material that is assembled to a desired mounting location.

The term "parallel" includes not only the case where the first wire harness and the second wire harness are parallel, but also the case where they are arranged substantially parallel. In other words, it refers to a state where the second wire harness is held so as to be aligned with the first wire harness that is inserted into the protector.

This invention allows the wire harness to be easily attached to the desired mounting location with a simple structure that simply requires inserting the insertion protrusion on the exterior body that sheathes the wire harness into the mounting hole provided at the mounting location.

The resin sheet material that constitutes the exterior body and the insertion protrusion is easier to process than resins such as polypropylene that are used in molding protectors, and is lightweight, so it is possible to reduce the weight while improving the productivity of wire harness wiring structures in which the exterior body is wrapped around a wire harness and harness mounting members.

The insertion protrusions are provided opposite each other on both sides in a width direction perpendicular to the longitudinal direction, and the opposed insertion protrusions are inserted in an overlapping state into the mounting hole.
This makes it possible to improve the rigidity of the insertion convex body in the width direction, so that the exterior body that is fitted around the wire harness can be reliably supported.

As an aspect of the present invention, the insertion convex body may be provided with a locking hole for locking a locking piece provided in the mounting hole in the insertion direction.
According to this invention, since the locking piece provided in the mounting hole is locked in the locking hole, the insertion protrusion can be stably supported in the mounting hole and the insertion protrusion can be prevented from falling out of the mounting hole. Therefore, even if an unintended external force acts on the wire harness or the harness mounting member, the harness mounting member can be reliably supported and prevented from falling out.

As a further aspect of the present invention, the locking hole may be provided in plurality at predetermined intervals in the insertion direction.
The predetermined intervals may be not only regular intervals but also irregular intervals.

According to this invention, the insertion protrusion can be engaged in the mounting hole in stages, so the insertion amount of the insertion protrusion can be selected according to the outer diameter of the wire harness attached to the exterior body. This allows for compactness in the insertion direction and restricts movement of the wire harness in the width direction.

As a further aspect of the present invention, a plurality of the insertion convex bodies may be provided at predetermined intervals in the longitudinal direction.
According to the present invention, the exterior body that is attached to the wire harness can be supported by the plurality of insertion protrusions, thereby improving the stability of the harness attachment member attached to the attachment location.

As a further aspect of the present invention, the insertion convex body may be provided on both sides in a width direction perpendicular to the longitudinal direction.
The above-mentioned provision on both sides in the width direction includes not only the case where the insertion convex bodies are at the same position in the longitudinal direction, but also the case where they are at different positions in the longitudinal direction.

This invention makes it possible to support the exterior body that is wrapped around the wire harness at two or more points in the width direction, improving the stability of the harness attachment member that is attached to the attachment location. It also makes it possible to restrict the exterior body that wraps around the wire harness from moving in the width direction.

As a further aspect of the present invention, the exterior body may be provided with a folding portion extending in the longitudinal direction at a midpoint in the width direction, the folding portion folding the exterior body in the width direction.
According to the present invention, by folding the exterior body at the bending portion, the wire harness can be surrounded by the folded exterior body, so that the wire harness can be protected more reliably. Also, since the exterior body can be folded and deformed according to the mounting location, versatility can be improved.

As a further aspect of the present invention, the bent portion may be provided in plurality at predetermined intervals in the width direction.
According to the present invention, the bending position can be appropriately selected according to the outer diameter of the wire harness, so that the exterior body can be wrapped around wire harnesses of various outer diameters, the wire harness can be protected by the exterior body, and the movement of the wire harness in the width direction can be restricted.

As a further aspect of the present invention, the insertion protrusions may be provided opposite each other on both sides in a width direction perpendicular to the longitudinal direction, and the opposed insertion protrusions may be inserted in a state overlapping the mounting hole.
According to this invention, the rigidity of the insertion convex body in the width direction can be improved, so that the exterior body that is attached to the wire harness can be reliably supported.

In another aspect of the invention, the mounting holes may be provided along the longitudinal direction, and the insertion protrusions may be arranged in multiple locations along the longitudinal direction, and may be provided at different positions on one side and the other side in the width direction perpendicular to the longitudinal direction.

The above-mentioned phrase "arranged in multiple locations along the longitudinal direction and provided at different positions on one side and the other side in the width direction perpendicular to the longitudinal direction" includes cases where the insertion protrusions are provided alternately on one side and the other side of the width direction of the exterior body along the longitudinal direction, and cases where one or more insertion protrusions are irregularly provided at a predetermined interval along the longitudinal direction on one side and the other side of the width direction of the exterior body.

This invention allows the number of insertion protrusions inserted into the mounting hole to be reduced while stably mounting the exterior body that covers the wire harness. In addition, when the insertion protrusions are provided alternately on both sides of the width of the exterior body along the longitudinal direction, the exterior body that is attached to the wire harness can be supported more stably and reliably.

In another aspect of the invention, the insertion protrusions may be provided on both sides in a width direction perpendicular to the longitudinal direction, and the exterior body may be inclined inward in the width direction perpendicular to the longitudinal direction as the insertion protrusions move in the insertion direction when the insertion protrusions are inserted into the mounting hole.

The above-mentioned inclination toward the inside in the width direction perpendicular to the longitudinal direction includes cases where the insert protrusions provided on both sides of the exterior body in the width direction are inserted into mounting holes formed along the longitudinal direction to tilt the exterior body, cases where the insert protrusions provided on both sides of the exterior body in the width direction are inserted into mounting holes provided at intervals shorter than the width length of the exterior body to tilt the exterior body, and cases where a folding portion is provided in part of the exterior body and the exterior body is folded to tilt the exterior body.

According to this invention, the space for accommodating the wire harness formed on the inside of the exterior body in the width direction can be made small to fit the wire harness, so that the positional deviation of the wire harness wrapped around the exterior body can be suppressed.

This invention provides a harness mounting member that can mount a wire harness to a mounting location with a simple structure, and a wire harness routing structure in which the harness mounting member to which the wire harness is mounted is attached to a protector through which another wire harness is inserted.

Fig. 3 shows an explanatory diagram of the cover 30 constituting the protector 10, Fig. 4 shows a plan view of a thermoplastic resin foam sheet material 50 (hereinafter referred to as the sheet material 50) from which the harness attachment member 40 is cut out, and Fig. 5 shows an explanatory diagram of the harness attachment member 40. Fig. 6 shows a plan view and a cross-sectional view explaining the assembled state of the harness attachment member 40 to the cover 30.

3, 5 and 6 will now be described in detail.
Fig. 3(a) shows a plan view of the cover 30, Fig. 3(b) shows an enlarged plan view of the mounting hole 33, and Fig. 3(c) shows a cross-sectional view taken along the line A-A in Fig. 3(a).

FIG. 6(a) shows a plan view of the cover 30 to which one harness mounting member 40 is attached, and FIG. 6(b) shows a cross-sectional view taken along the line BB in FIG. 6(a).
In FIG. 6A, in order to clarify the position of the exterior side surface 412 relative to the cover surface 31, the exterior side surface 412, the insertion protrusion 42, and the mounting hole 33 which are hidden by the cover surface 31 and cannot be seen are shown by dotted lines.

Here, the up-down direction in FIG. 1 is the up-down direction Z, and the direction in which the first harness WH1 and the second harness WH2 extend is the longitudinal direction L. Also, the width direction of the protector 10 in FIG. 1 is the width direction W. Note that the longitudinal direction L, the width direction W, and the up-down direction Z are all orthogonal to each other.

As shown in FIG. 1, the wire harness arrangement structure 1 is composed of a first harness WH1 arranged in a vehicle, a protector 10 through which a portion of the first harness WH1 is inserted along the longitudinal direction L, two second harnesses WH2 arranged parallel to the first harness WH1, and a harness attachment member 40 that attaches the second harnesses WH2 to the attachment points of the protector 10.

The first harness WH1 electrically connects the standard electrical devices installed in the vehicle, such as the battery, and is routed along a specified routing path in the vehicle. A portion of the first harness WH1 is inserted into the protector 10 to prevent interference with other components installed in the vehicle.

The second harness WH2 is a bundle of electric wires that electrically connects optional equipment installed as an option with standard electrical equipment such as a battery, and is routed in the vehicle when the optional equipment is installed. The second harness WH2 is routed so as to be parallel to the first harness WH1 at least at the point where the first harness WH1 is inserted into the protector 10.

The protector 10 is made of a thermoplastic resin foam sheet material made of a synthetic resin foam molded into a foamed or porous shape. As shown in Figures 1 and 2, this protector 10 has a protector body 20 with a concave cross section and a cover 30 that covers the opening of the protector body 20.

As shown in Figures 1 and 2, the protector body 20 is composed of a bottom surface 21 on which the first harness WH1 is placed, and body side surfaces 22, 22 arranged at both ends of the bottom surface 21 in the width direction W. The bottom surface 21 and the body side surfaces 22 form a cross-sectional concave shape that opens upward, and an internal space S1 is formed inside that passes through along the longitudinal direction L.

The cover 30 has a concave cross section that opens downward (in the opposite direction to the direction in which the body side surface 22 stands upright relative to the bottom surface 21), and when assembled to the protector body 20, it closes the opening in the protector body 20.

In more detail, as shown in Figures 1 and 2, the cover 30 is composed of a cover surface 31 that faces the bottom surface 21 of the protector 10, and cover side surfaces 32 that stand upright from both ends of the cover surface 31 in the width direction W.

The cover surface 31, like the bottom surface 21, is a flat plate extending along the longitudinal direction L, and as shown in FIG. 3(a), a plurality of mounting holes 33 penetrating in the plate thickness direction (vertical direction Z) are provided along the longitudinal direction L and width direction W.

The mounting hole 33 is configured in a generally I-shape in plan view, with the central portion of the long side of the generally rectangular through hole protruding inward in the width direction W. As shown in FIG. 3(b), this mounting hole 33 is integrally configured with a first wide hole 331, a narrow hole 332, and a second wide hole 333.

The first wide hole 331 is a through hole arranged on one side of the narrow hole 332 in the longitudinal direction L, and its length in the width direction W (width D1) is configured to be slightly wider than the plate thickness of the harness mounting member 40.
The second wide hole 333 is disposed on the other side of the narrow hole 332 in the longitudinal direction L, and has the same configuration as the first wide hole 331 .

The narrow hole 332 is a through hole whose length in the width direction W (spacing D2) is shorter than the first wide hole 331 and the second wide hole 333. The narrow hole 332 is formed by a pair of locking pieces 34, 34 that protrude inward from both ends in the width direction W of the substantially rectangular outer frame.

The locking pieces 34 have the same plate thickness as the cover surface 31, and protrude inward in the width direction W from the outer ends in the width direction W of the first wide hole 331 and the second wide hole 333. In addition, both end portions in the longitudinal direction L of the locking pieces 34 that form the narrow hole 332 are inclined toward the inside in the width direction W as they move inward in the longitudinal direction L from the other end in the longitudinal direction L of the first wide hole 331 and one end in the longitudinal direction L of the second wide hole 333. The spacing D2 in the width direction W of the locking pieces 34 is configured to be approximately half the length of the plate thickness of the harness mounting member 40.

The mounting holes 33 thus configured are arranged in parallel, four along the longitudinal direction L and four along the width direction W, for a total of 16 mounting holes. The number of mounting holes 33 provided on the cover surface 31 can be adjusted as appropriate.

The harness attachment member 40 to be attached to the cover 30 is formed by bending an attachment mold 40A cut from a sheet material 50 made of a foamed or porous, thermoplastic, and bendable synthetic resin foam (see Figures 4 and 5).

More specifically, the mounting die 40A used to cut out the sheet material 50 is composed of a substantially rectangular plate-like body 41A and four insertion protrusions 42A that protrude outward in the width direction W from both ends of the plate-like body 41A in the width direction W, as shown in FIG. 4.

The plate-like body 41A has folds F1, F1 that divide the plate-like body 41A into approximately three equal parts in the width direction W after punching out the plate-like body 41A from the sheet material 50, and a fold F2 that divides the plate-like body 41A into two equal parts in the width direction W, along the longitudinal direction L (see FIG. 5(a)). Here, the portion surrounded by the folds F1, F1 is the top surface corresponding portion 411A, and the portion outside the fold F1 in the width direction W is the side surface corresponding portion 412A.

The insertion convex body type 42A is a band-like body extending in the width direction W, with a tapered tip. Two insertion convex body types 42A are provided on one side of the width direction W of the plate-like body 41A, and two on the other side, spaced apart at a predetermined interval along the longitudinal direction L. The insertion convex body types 42A provided on one side of the width direction W and the insertion convex body types 42A provided on the other side are alternately arranged along the longitudinal direction L.

The insertion convex mold 42A has three through holes 43A arranged in the width direction W, which correspond to the locking holes 43 that penetrate in the plate thickness direction after punching out the sheet material 50 (see FIG. 5(b)). The through holes 43A are configured so that the length in the longitudinal direction L is approximately equal to the length of the mounting hole 33, and the length in the width direction W is the same as the plate thickness of the cover surface 31.

Here, the density of the resin sheet constituting the above-mentioned sheet material 50 is not particularly limited. For example, in order to prevent anisotropy of mechanical properties, that is, to make the mechanical properties isotropic, and improve the degree of freedom in designing the harness attachment member 40, and to further improve the strength against stress on the second harness WH2 housed in the harness attachment member 40, the density is preferably 200 kg/m ³ or more and 1000 kg/m ³ or less. In order to further improve the balance between light weight and mechanical strength, the density is more preferably 300 kg/m ³ or more and 600 kg/m ³ or less, and particularly preferably 350 kg/m ³ or more and 550 kg/m ³ or less.

The thickness of the sheet material 50 is not particularly limited. For example, in order to improve the balance between the ease of folding and the mechanical strength, particularly the mechanical strength against the stress on the second harness WH2 housed in the harness mounting member 40, the thickness is preferably 0.50 mm or more and 4.0 mm or less, and more preferably 1.0 mm or more and 2.5 mm or less. The thermoplastic resin foam sheet may have a non-foamed layer formed on both sides or one side.

That is, the sheet material 50 (thermoplastic resin foam sheet) may have a foam layer and a non-foam layer formed on the foam layer. By forming a non-foam layer on the surface of the thermoplastic resin foam sheet, the mechanical strength of the harness mounting member 40 is improved, and the protective performance of the second harness WH2 housed therein is further improved. The thickness of the non-foam layer is not particularly limited, and may be, for example, 10 μm or more and 100 μm or less.

The bubble density of the foamed layer of the sheet material 50 is not particularly limited, and the lower limit is preferably 800 bubbles/ ^mm3 or more, and particularly preferably 1000 bubbles/ ^mm3 or more, from the viewpoint of more reliably preventing anisotropy of mechanical properties. On the other hand, the upper limit of the bubble density can be, for example, 1010 bubbles/mm3 or ^less , from the viewpoint of more reliably obtaining excellent mechanical strength.

In the mounting mold 40A cut out from the sheet material 50 configured in this manner, the side surface corresponding portion 412A can be folded relative to the top surface corresponding portion 411A at the folds F1, F1 to form a harness mounting member 40 with a concave cross section that opens downward.

That is, the harness attachment member 40 is composed of an exterior body 41, which is composed of an exterior upper surface 411 corresponding to the upper surface corresponding portion 411A and an exterior side surface 412 corresponding to the side surface corresponding portion 412A, and an insertion convex body 42 corresponding to the insertion convex body type 42A. The bent portion where the exterior side surface 412 is bent relative to the exterior upper surface 411 is referred to as a first bent portion 44.

The exterior body 41, which is composed of the exterior upper surface 411 and the exterior side surface 412, is open downward and has a concave cross-section with an insertion space S2 through which the second harness WH2 can be inserted (see Figure 2). At the center of the width direction W of the exterior upper surface 411, a second fold 45 that corresponds to the fold F2 in the mounting mold 40A extends along the longitudinal direction L.

The insertion protrusions 42 provided on the exterior side surface 412 on one side in the width direction W and the insertion protrusions 42 provided on the exterior side surface 412 on the other side in the width direction W are alternately arranged at a predetermined interval along the longitudinal direction L so as not to face each other (see FIG. 5(c)).

The insertion convex body 42 has a generally rectangular shape in a plan view protruding downward, and the length in the longitudinal direction L is equal to the length in the longitudinal direction L of the mounting hole 33. The main surface is provided with three locking holes 43 arranged side by side in the up-down direction Z, penetrating along the plate thickness direction (width direction W). The length in the longitudinal direction L of the locking holes 43 is equal to the length in the longitudinal direction L of the narrow hole 332.
The three locking holes 43 arranged side by side in this manner are referred to as locking holes 43a, 43b, and 43c, in that order from the top.

Next, a method for assembling the harness attachment member 40 to the protector 10 and the assembled state will be briefly described with reference to FIG.
First, the attachment mold 40A is punched out from the sheet material 50, and a through hole 43A is provided at a predetermined location of the insertion convex mold 42A. Then, the side surface corresponding portion 412A is folded relative to the top surface corresponding portion 411A at the folds F1, F1 to manufacture the harness attachment member 40, and the second harness WH2 is inserted into the insertion space S2 from the opening and fixed.

The first harness WH1 is inserted into the internal space S1 through the opening in the protector body 20, and the cover 30 is attached to close the opening. Then, the insertion protrusion 42 is inserted into the mounting hole 33 provided in the cover 30 (see Figures 6(a) and (b)).

At this time, since the narrow hole 332 is slightly shorter than the plate thickness of the insertion protrusion 42, the insertion protrusion 42 is press-fitted into the mounting hole 33. Here, since the cover 30 is made of a flexible thermoplastic resin sheet and the harness mounting member 40 is made of the sheet material 50, the mounting hole 33 and the insertion protrusion 42 can be deformed by inserting the insertion protrusion 42. This allows the insertion protrusion 42 to be inserted into the mounting hole 33.
Then, by inserting the locking hole 43 to a position corresponding to the mounting hole 33, the narrow hole 332 fits into the locking hole 43, and the narrow hole 332 and the locking hole 43 are locked together (see FIG. 6B).

The insertion protrusion 42 is provided with a plurality of locking holes 43 along the vertical direction Z. This allows the insertion protrusion 42 to be inserted so that the locking holes 43b and 43c lock with the locking pieces 34 according to the outer diameter of the second harness WH2.
That is, by providing a plurality of locking holes 43 along the vertical direction Z, it is possible to select the locking hole 43 according to the outer diameter of the second harness WH2 inserted into the insertion space S2 of the harness attachment member 40.

Furthermore, by folding the exterior upper surface 411 at the second folding portion 45, the harness attachment member 40 can be made substantially flat (see FIG. 7). This allows the harness attachment member 40 to be exteriorly mounted by sandwiching the third harness WH3, which has a smaller outer diameter than the second harness WH2, in the harness arrangement space S3 formed on the exterior upper surface 411 folded substantially flat.

In addition, since the insertion protrusions 42 protruding from one side of the exterior side surface 412 and the insertion protrusions 42 protruding from the other side are alternately provided, by making the harness mounting member 40 substantially flat, the insertion protrusions 42 can be arranged in a line in the longitudinal direction L. This allows the insertion protrusions 42 to be inserted into each of the mounting holes 33 arranged along the longitudinal direction L. Therefore, the exterior body 41 that protects the thin-diameter third harness WH3 can be supported while having enough strength to erect the insertion protrusions 42 against the cover surface 31.

In this way, the harness mounting member 40 is a member that mounts the second harness WH2 to the mounting location configured by the sheet material 50. This harness mounting member 40 is equipped with an exterior body 41 that covers at least a portion of the second harness WH2, and an insertion protrusion 42 that protrudes from the exterior body 41 in the width direction W that intersects with the longitudinal direction L of the second harness WH2 and is inserted into a mounting hole 33 provided in the mounting location (cover surface 31 of the protector 10). The exterior body 41 and the insertion protrusion 42 are configured by the sheet material 50.

The wire harness wiring structure 1 also includes a first harness WH1 that is wired along a predetermined wiring path, a protector 10 that is made of a sheet material 50 and through which the first harness WH1 is inserted, a second harness WH2 that is arranged parallel to the first harness WH1, and the above-mentioned harness mounting member 40 that mounts the second harness WH2 to the mounting location of the protector 10.

This allows the second harness WH2 to be easily attached to the desired attachment location (cover surface 31) with a simple structure that simply requires inserting the insertion protrusion 42 on the exterior body 41 that sheathes the second harness WH2 into the attachment hole 33 provided in the protector 10.

The sheet material 50 constituting the exterior body 41 and the insertion protrusion 42 is lighter and easier to process than polypropylene resins that constitute resin-molded protectors. This makes it possible to reduce the weight of the wire harness arrangement structure 1 and the harness mounting member 40 in which the exterior body 41 is fitted to the second harness WH2 while improving the productivity of the wire harness arrangement structure 1 and the harness mounting member 40.

In addition, the insertion protrusion 42 is provided with a locking hole 43 that locks the locking piece 34 provided in the mounting hole 33 in the insertion direction, so that the locking piece 34 provided in the mounting hole 33 is locked in the locking hole 43. This allows the insertion protrusion 42 to be stably supported in the mounting hole 33 and prevents the insertion protrusion 42 from falling out of the mounting hole 33. Therefore, even if an unintended external force acts on the second harness WH2 or the harness mounting member 40, it is possible to reliably support the harness mounting member 40 and prevent it from falling out.

Furthermore, by providing multiple locking holes 43 at a predetermined interval in the insertion direction, the insertion protrusion 42 can be locked in the mounting hole 33 in stages. This allows the insertion amount of the insertion protrusion 42 to be selected according to the outer diameter of the second harness WH2 attached to the exterior body 41, making it possible to reduce the size of the second harness WH2 in the insertion direction and restricting movement of the second harness WH2 in the width direction W.

In addition, since multiple insertion protrusions 42 are provided at predetermined intervals in the longitudinal direction L, the multiple insertion protrusions 42 can be inserted into the mounting hole 33 to support the exterior body 41 that is attached to the second harness WH2. This improves the stability of the harness mounting member 40 attached to the cover surface 31, which is the mounting location.

Furthermore, by providing the insertion protrusions 42 on both sides in the width direction W perpendicular to the longitudinal direction L, the exterior body 41 attached to the second harness WH2 can be supported at least at two or more points in the width direction W. This improves the stability of the harness attachment member 40 attached to the cover surface 31, which is the attachment point.

In addition, the exterior body 41 is provided with a first bending portion 44 extending in the longitudinal direction L, which bends the exterior body 41 in the width direction W, at a midpoint in the width direction W. As a result, by bending the exterior body 41 at the first bending portion 44, an exterior side surface 412 is formed that is bent relative to the exterior upper surface 411, and the second harness WH2 can be surrounded by the folded exterior upper surface 411 and exterior side surface 412. This makes it possible to more reliably protect the second harness WH2. In addition, since the exterior body 41 can be bent and deformed according to the installation location, versatility can be further improved.

In addition to the first bend portion 44, the second bend portion 45 is provided at a predetermined interval in the width direction W of the first bend portion 44, so that the bending position can be appropriately selected according to the outer diameter of the second harness WH2. This allows the exterior body 41 to be fitted around second harnesses WH2 of various outer diameters, and the exterior body 41 can protect the second harness WH2, while also restricting movement of the second harness WH2 in the width direction W.

As shown in FIG. 7, the mounting holes 33 into which the insertion protrusions 42 are inserted are provided along the longitudinal direction L, and the insertion protrusions 42 are arranged in multiple locations along the longitudinal direction L, and are provided at different positions on one side and the other side of the width direction W perpendicular to the longitudinal direction L.

This allows the exterior body 41 that covers the second harness WH2 to be stably attached to the protector 10 (cover 30) while reducing the number of insertion protrusions 42 inserted into the mounting holes 33. In addition, since the insertion protrusions 42 are provided alternately on both sides of the width direction W of the exterior body 41 along the longitudinal direction L, the exterior body 41 that is covered by the second harness WH2 can be more stably and reliably supported.

Furthermore, as shown in FIG. 7, the insertion protrusions 42 are provided on both sides in the width direction W perpendicular to the longitudinal direction L, and the exterior body 41 is inclined inward in the width direction W perpendicular to the longitudinal direction L as it moves downward when the insertion protrusions 42 are inserted into the mounting holes 33 provided along the longitudinal direction L.

This allows the storage space for the second harness WH2 formed on the inside of the exterior body 41 in the width direction W to be made smaller to match the outer diameter of the second harness WH2, thereby preventing the second harness WH2 wrapped around the exterior body 41 from shifting out of position.

The present invention is not limited to the above-described embodiment.

For example, in this embodiment, the sheet material 50 is made of a synthetic resin foam that is molded into a foamed or porous shape, has thermoplastic properties, and is bendable, but is not limited to this configuration. For example, it may be made of a synthetic resin foam that is molded into a foamed or porous shape, has thermosetting properties, and is bendable. Furthermore, it may be made of a synthetic resin instead of a synthetic resin foam. Note that the sheet material 50 is preferably a synthetic resin foam sheet material made of a synthetic resin foam that is molded into a foamed or porous shape.

In this embodiment, the first harness WH1 and the second harness WH2 are arranged in parallel, but the present invention also includes cases where they are arranged approximately in parallel. Specifically, the second harness WH2 only needs to be held so as to be aligned with the first harness WH1 inserted through the protector 10, and the second harness WH2 may be inclined relative to the first harness WH1.

In addition, since the harness attachment member 40 is made of the flexible sheet material 50 , the harness attachment member 40 with the protector body 20 exteriorly mounted thereon can also be disposed at an angle relative to the cover 30 .
Furthermore, although the locking holes 43 provided in the insertion convex body 42 are arranged at equal intervals, they may be arranged at irregular intervals in accordance with, for example, a preset value of the outer diameter of the electric wire.

In addition, in this embodiment, the locking pieces 34, 34 are fitted into the locking holes 43 from the width direction W to be locked, but this is not limited to the configuration. For example, the locking protrusions 43x may be inserted into the mounting holes 33x shown in Figures 8 to 12 to be locked.

The following describes the harness mounting member 40x having the locking protrusion 43x and the wire harness arrangement structure 1x in which the harness mounting member 40x is inserted into the mounting hole 33x and the second harness WH2 is attached to the protector 10, with reference to Figures 8 to 12. Note that in Figures 8 to 12, the same components as those in Figures 1 to 7 are given the same reference numerals and detailed descriptions thereof are omitted.

FIG. 10 shows a plan view explaining the configuration of the cover 30x corresponding to the cover 30, and FIG. 11 shows a cross-sectional view explaining the method of inserting the harness attachment member 40x into the cover 30x.

9 to 12 will now be described in detail.

Figure 12(a) shows a plan view of the cover 30x with the harness mounting member 40x attached, and Figure 12(b) shows a cross-sectional view taken along the line C-C in Figure 12(a). Figure 12(c) shows an enlarged side view of the insertion protrusion 42x inserted into the mounting hole 33x. Note that in Figure 12(a), the exterior side surface 412, the insertion protrusion 42x, and the mounting hole 33x, which are hidden by the cover surface 31, are shown by dotted lines.

The wire harness arrangement structure 1x, like the wire harness arrangement structure 1, is composed of a protector 10x composed of a protector body 20 and a cover 30x, a first harness WH1 inserted into the protector 10x, a harness attachment member 40x, and a second harness WH2 inserted into the harness attachment member 40x.

The harness attachment member 40x corresponding to the harness attachment member 40 is formed by bending a mold cut out from a sheet material 50 made of a foamed or porous, thermoplastic, and bendable synthetic resin foam.

The harness attachment member 40x is composed of an exterior body 41 and an insertion protrusion 42x. As shown in Fig. 9, the insertion protrusion 42x is a strip-shaped body extending in the width direction W and has a tapered tip. The insertion protrusion 42x has three locking protrusions 43x arranged in parallel along the width direction W, protruding on both sides in a direction intersecting with the longitudinal direction of the insertion protrusion 42x.
Here, the length of the insertion convex body 42x in the intersecting direction is taken as an axial width l1, and the length of the locking convex portion 43x in the intersecting direction is taken as a locking piece width l2.

As shown in Figures 8 and 10, the cover 30x is composed of a cover surface 31x that faces the bottom surface 21 of the protector 10, and cover side surfaces 32 that stand upright from both ends of the cover surface 31x in the width direction W.

As shown in FIG. 10, the cover surface 31x is a flat plate configured similarly to the cover surface 31, and is provided with mounting holes 33x instead of the mounting holes 33.
As shown in FIG. 10B, the mounting hole 33x is a through hole that is generally cross-shaped in plan view, and is integrally formed with a one-end side hole 331x, a central hole 332x, and an other-end side hole 333x.

As shown in FIG. 10(b), the one-end side hole 331x constitutes one end side of the mounting hole 33 in the width direction W (upper side in FIG. 10(b)), and the other-end side hole 333x constitutes the other end side of the mounting hole 33 in the width direction W (lower side in FIG. 10(b)).

The length in the longitudinal direction L of the one-end side hole 331x and the other-end side hole 333x is the same as the locking piece width l2. The distance between the one-end side hole 331x and the other-end side hole 333x in the mounting hole 33 adjacent in the width direction W is equal to the length of the short side of the exterior body 41, which is made of a substantially rectangular flat plate (length in the width direction W).

The central hole 332x is sandwiched between the one end side hole 331x and the other end side hole 333x in the attachment hole 33x. The length of the central hole 332x in the longitudinal direction L is the same as the shaft width l1.
The length in the width direction W of the one end side hole 331x, the central hole 332x, and the other end side hole 333x is the same as the plate thickness of the insertion convex body 42x.

Next, a method for locking and fixing the insertion protrusion 42x to the mounting hole 33x thus configured and the locked state will be briefly described.
For example, when a harness attachment member 40x formed with a concave cross section as shown in FIG. 8 is assembled to a cover 30x, an insertion protrusion 42x extending from an exterior side surface 412 is inserted into a central hole 332x (see FIGS. 11(a) and 11(b)).

Then, when the exterior body 41 is at the desired height, the locking protrusion 43x is slid into the one end side hole 331x or the other end side hole 333x (see Figures 11(c) and 11(d)). This allows the locking protrusion 43x to be locked into the one end side hole 331x or the other end side hole 333x (see Figures 12(a) and 12(b)).

To explain more specifically, when inserting the insertion protrusion 42 on one side in the width direction W into the mounting hole 33, the insertion protrusion 42 inserted into the central hole 332x is inserted, and when the exterior body 41 is at the desired height, the locking protrusion 43x is slid into the one-end side hole 331x (see Figures 12(b) and 12(d)).

On the other hand, when inserting the insertion protrusion 42 on the other side in the width direction W into the mounting hole 33, the insertion protrusion 42 inserted into the central hole 332x is inserted, and the locking protrusion 43x is slid into the other end side hole 333x at a position where the exterior body 41 is at the desired height. This allows the locking protrusion 43x to lock into the mounting hole 33x, as shown in Figures 12(a) and 12(b).

Also, as shown in FIG. 13, the harness attachment member 40x, which is formed by bending the second bend 45 to have a generally flat shape, can be attached to the cover surface 31x. In this case, the four insertion protrusions 42x arranged in a line along the longitudinal direction L can be engaged with the attachment holes 33x provided along the longitudinal direction L.

Here, since the exterior body 41 bent into a substantially flat plate shape has flexibility, the locking protrusions 43x are biased outward in the width direction W, so that they are securely locked into the one end side hole 331x or the other end side hole 333x. This allows the harness attachment member 40x to be attached to the protector 10x more securely.

In addition, in the above embodiment, the insertion convex body 42 and the insertion convex body 42x are provided at different positions in the longitudinal direction on the exterior side surfaces 412, 412, but as shown in the development view of FIG. 14, they may be at the same position in the longitudinal direction. In other words, the insertion convex bodies 42 may be provided at positions facing each other.

Furthermore, when the insertion protrusions 42 and 42x are provided at positions facing each other, they may be overlapped and inserted into the mounting holes 33 and 33x.
In this way, the insertion protrusions 42 and the insertion protrusions 42x are provided opposite each other on both sides of the width direction W of the outer body 41, and by inserting the opposing insertion protrusions 42 and the insertion protrusions 42x in an overlapping state into the mounting holes 33 and the mounting holes 33x, etc., the rigidity of the insertion protrusions 42 and the insertion protrusions 42x in the width direction W can be improved, and the outer body 41 attached to the second harness WH2 can be reliably supported.

In addition, in the above embodiment, the mounting hole 33 into which the insertion protrusion 42 is inserted is provided on the cover surface 31, but this is not limited to the cover surface 31. For example, as shown in FIG. 15, a mounting point for mounting the harness mounting member 40 may be provided on the outer side of the cover side surface 32 in the width direction W.

Furthermore, the location where the harness mounting member 40 is attached does not have to be limited to the protector 10. For example, as shown in FIG. 16, a mounting member 60 made of a sheet material 50 may be attached to a desired mounting location, such as a vehicle body panel P, and the harness mounting member 40 that covers the second harness WH2 routed along a specified routing path may be attached.

In addition, since the mounting member 60 is made of the sheet material 50, the shape can be processed and deformed as needed. Therefore, it can be processed as needed to match the outer shape of the vehicle body panel P, as well as the outer shape of a protector that protects a wire harness that is already installed in the vehicle. This allows the second harness WH2, etc. to be attached to a wire harness that is already installed.

In addition, in this embodiment, the protector 10 is made of a thermoplastic resin foam sheet material made of a synthetic resin foam molded into a foam or porous shape, but for example, only the cover 30 may be made of a thermoplastic resin foam sheet material. Also, the protector 10 does not necessarily have to be made of a thermoplastic resin foam sheet material as long as the harness attachment member 40 can be attached.

Furthermore, at least the portion where the harness mounting member 40 is attached may be made of a thermoplastic resin foam sheet material. In other words, if the harness mounting member 40 is attached to the side, only the side may be made of a thermoplastic resin foam sheet material, and if the harness mounting member 40 is attached to the bottom, only the bottom may be made of a thermoplastic resin foam sheet material.

As shown in FIG. 7, the insertion protrusions 42 are arranged alternately on one side and the other side of the width direction W of the exterior body 41 along the longitudinal direction L, but this does not necessarily have to be alternating, and one or more insertion protrusions 42 may be arranged irregularly at a predetermined interval along the longitudinal direction L on one side and the other side of the width direction W of the exterior body 41.

Furthermore, in the example shown in FIG. 7, the insertion protrusions 42 provided on both sides of the exterior body 41 in the width direction W are inserted into mounting holes 33 formed along the longitudinal direction L to tilt the exterior body 41. However, the exterior body 41 may also be tilted by inserting the insertion protrusions 42 provided on both sides of the exterior body 41 in the width direction into mounting holes 33 provided at intervals shorter than the length of the exterior body 41 in the width direction W. Furthermore, a bent portion may be provided in a part of the exterior body 41, and the exterior body 41 may be bent to tilt it.

Note that the above contents can be implemented in various ways, and the combinations can be changed as appropriate as long as the effect is achieved.
