[0003] [Patent Document 1] JP 2012-115022 A Summary of the Invention [Problem to be solved by the invention]

[0004] Since various items are mounted on a vehicle, it is possible that the items may be on the path of the harness. In this case, it is necessary to route the harness while detouring the parts. However, if the upper wall of the detouring path is weak in strength, when a load is applied to the upper wall, the load may also be applied to the harness, which may lead to damage to the harness.

[0005] An object of the present disclosure is to provide a protector that can protect a harness. [Means for solving the problem]

[0006] The protector that solves the above problem comprises a protector main body through which a harness is passed and at least a portion of which is placed in the space between opposing first and second items, a fixing portion that fixes the protector main body to the first item, and a suppression portion that suppresses tilting of the protector main body around the fixing portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] First, the embodiments of the present disclosure will be listed and described. [1] The protector disclosed herein comprises a protector body through which a harness is passed and at least a portion of which is positioned in a space between opposing first and second items, a fixing portion that fixes the protector body to the first item, and a suppression portion that suppresses tilt of the protector body from the fixing portion.

[0010] According to the configuration of this example, when a load is applied to the protector from above, the protector may tilt around the fixed portion, but the suppression portion provided on the protector makes it difficult for the protector to tilt. If the protector tilts, the harness may be pulled and loaded at the opening in the protector through which the harness passes, but with the configuration of this example, this situation is unlikely to occur. Therefore, it is possible to protect the harness.

[0011] [2] The protector body is formed in a shape that crosses the columnar first article. With this configuration, it is possible to effectively utilize the space around the first article and ensure a route for the harness.

[0012] [3] The suppression portion is provided in plurality. With this configuration, even if a load applied to the protector from above causes the protector to tilt around the fixing portion, the load is dispersed by the multiple suppression portions, making it possible to prevent the protector from tilting.

[0013] [4] The protector body includes a first harness insertion portion disposed opposite the top surface of the columnar first article, and a second harness insertion portion disposed opposite the side surface of the first article. The fixing portion is disposed on the back surface of the first harness insertion portion. The suppressing portion is disposed on the inner surface of the second harness insertion portion. With this configuration, even if a load applied to the protector from above causes the protector to tilt around the fixing portion, the suppressing portion abutting the side surface of the first article makes it possible to firmly hold the position of the protector.

[0014] [5] The first harness insertion portion has a pair of arms disposed in the space. The second harness insertion portion is formed in a shape that connects the pair of arms. The fixing portion is disposed in the arms. With this configuration, even if an obstacle is present at the midpoint of the pair of arms, the harness can be detouring by the protector and returned to the original wiring route that would be taken if no detouring were to be taken.

[0015] [6] The suppression portion suppresses the inclination of the protector body by bending the base end with the tip as a fulcrum. With this configuration, the shape of the suppression portion can be such that there is no member at the tip of the suppression portion. Therefore, it is possible to prevent the tip of the suppression portion from interfering with the surrounding wall surface or the like when the suppression portion bends.

[0016] [7] The suppression portion is a spring portion that applies a load to the protector body to suppress tilt by a bending reaction force. With this configuration, the suppression portion can be configured with a simple spring structure.

[0017] [Details of the embodiment of the present disclosure] Specific examples of the protector of the present disclosure will be described below with reference to the drawings. Note that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In each drawing, for convenience of explanation, some of the configuration may be shown exaggerated or simplified. Furthermore, the dimensional ratios of each part may differ from the actual ones.

[0018] As shown in Fig. 1, a wire harness 1 electrically connects electrical components provided in a vehicle. The electrical components include, for example, various ECUs, a motor, and an engine. The wire harness 1 includes a harness 2 and a protector 3 that passes the harness 2 inside midway through its path to protect it. The harness 2 may be either a single electric wire or multiple electric wires.

[0019] As shown in Fig. 3, the protector 3 is constructed by assembling two housings 4, 5. In this example, the protector 3 is constructed by assembling an upper housing 4 and a lower housing 5. In this example, the two housings 4, 5 are assembled and fixed via a plurality of snap-fit ​​portions 6. In the protector 3, the internal space of the two housings 4, 5 serves as a location for storing the harness 2.

[0020] As shown in Fig. 2, the protector 3 includes a protector body 9 through which the harness 2 passes. At least a portion of the protector body 9 is disposed in a space 12 between a first article 10 and a second article 11 facing each other. The first article 10 is preferably a cross member extending in the left-right direction of the vehicle body. The second article 11 is preferably an interior floor surface (carpet, etc.), for example. The space 12 is preferably a narrow gap between the cross member and the interior floor surface.

[0021] As shown in FIG. 1, the protector body 9 is formed in a shape that crosses the columnar first article 10. In this example, the protector body 9 includes a first harness insertion portion 14 disposed on an upper surface 13 of the columnar first article 10, and a second harness insertion portion 15 disposed opposite to a side surface of the first article 10. In this example, the first harness insertion portion 14 is a pair of arms 16 disposed in the space 12. The second harness insertion portion 15 is formed in a shape that connects the pair of arms 16. In this way, the protector body 9 is formed in a shape in which the pair of arms 16 are connected at their bases, that is, in a so-called approximate U-shape.

[0022] An opening 17 is formed at the tip of each of the arms 16 for pulling the harness 2 into the inside of the protector body 9. A guide portion 18 is formed in the opening 17 for guiding the direction of the harness 2 exposed from the opening 17. The guide portion 18 is preferably, for example, a guide piece extending obliquely from a corner of the opening 17.

[0023] As shown in Fig. 4, the protector 3 has a fixing part 21 that fixes the protector body 9 to the first article 10 (cross member). The fixing part 21 is disposed on a rear surface 25 of the first harness insertion part 14 (arm part 16 in this example). A fixing part 21 is disposed on each arm part 16, and when there are two arms 16, two fixing parts 21 are provided on the protector body 9.

[0024] The fixing portion 21 includes a main body 22 and a protrusion 23 that engages with the first article 10 (cross member). The main body 22 is disposed on the back surface 25 of the protector main body 9 (arm portion 16) and is formed, for example, in a rectangular cross section. For example, a plurality of protrusions 23 are provided, and when two protrusions 23 are formed, they are disposed so as to face each other on both sides of the main body 22. The protrusions 23 are connected at their base to the main body 22 and are formed in a shape such that their tip opens out as it approaches the back surface of the protector main body 9.

[0025] As shown in Fig. 5, the pair of fixing portions 21 are arranged so as to be positioned on the same line as a line L1 extending in the arrangement direction of the arm portions 16. A pair of pushing pieces 24 are formed on both sides of the fixing portion 21 on the back surface 25 of the protector body 9 (arm portions 16). The pushing pieces 24 have, for example, a leaf spring structure. When the protector 3 is attached to the first article 10, the pushing pieces 24 cooperate with the fixing portions 21 to fix the protector 3 to the first article 10. The fixing portions 21 are arranged on the back surface 25 of the first harness insertion portion 14.

[0026] 6 and 7, the protector 3 includes a suppression portion 27 that suppresses tilt of the protector body 9 with the fixed portion 21 as a base point. A plurality of suppression portions 27 are provided, and in this example, two are provided. In this case, the suppression portions 27 are arranged side by side in the width direction of the protector body 9 (Y-axis direction in FIG. 6, etc.). The suppression portions 27 are arranged on the inner surface 28 of the second harness insertion portion 15. In this example, the suppression portion 27 is preferably a spring portion (spring structure) that applies a load to the protector body 9 to suppress tilt by bending reaction force.

[0027] Next, the operation of the protector 3 of this embodiment will be described. As shown in Fig. 2, when the wire harness 1 is routed along the first item 10, for example, the route path may be restricted by the presence of an obstacle inside the vehicle (see Fig. 2). In this case, a route that goes around the obstacle must be taken. In this case, if the route around the obstacle has to take the space 12 between the first item 10 and the second item 11, the wire harness 1 needs to be protected from an impact from the second item 11, so this is addressed by attaching a protector 3 to the first item 10 in the space 12 between the first item 10 and the second item 11 and passing the wire harness 1 through this protector 3.

[0028] In this example, the protector 3 is fixed to the first article 10 by attaching the fixing part 21 formed on the back surface of the protector body 9 to a recess 29 formed on the top surface of the first article 10. The recess 29 of the first article 10 is preferably an elongated hole, for example, to match the shape of the body 22 of the fixing part 21. If the shape of the fixing part 21 and the recess 29 is a combination of a rectangular cross-sectional shape and an elongated hole, this is advantageous for preventing the fixing part 21 from rotating in the recess 29 and for firmly fixing the fixing part 21 to the recess 29.

[0029] As shown in Fig. 8, when a load is applied to the top surface of the second article 11, the load is transmitted to the protector 3, and the protector 3 may tilt in the direction of arrow A in the figure, with the fixed part 21 as the base point. For example, if the second article 11 is the floor surface of a vehicle, the protector 3 will tilt with the fixed part 21 as the base point when the floor surface is stepped on. If the protector 3 tilts, the harness 2 will be pulled at the opening 17 of the protector 3, and an excessive load will be applied to the wire harness 1 near the opening 17. In addition, the back surface of the protector main body 9 will come into contact with the first article 10, which will lead to the generation of a hitting sound due to this contact.

[0030] 9(a), in this example, since the suppression section 27 is provided in the protector 3, even if a load is applied from above to the protector 3, a reaction force against the tilt load can be applied to the protector 3 by the suppression section 27. Therefore, even if a load is applied to the protector 3 from above, the protector 3 can easily maintain the initial position, making it possible to reduce the occurrence of the above-mentioned problem.

[0031] In addition, in the structure of this example, as shown in Fig. 9(b), the tip of the spring-structured suppression section 27 is constantly in contact with the first article 10, and when a tilting load is applied to the protector 3, a reaction force against the tilting load is applied by bending the base end of the suppression section 27 with the tip of the suppression section 27 as a fulcrum. In this structure, since there is no component shape at the tip of the suppression section 27, when the suppression section 27 bends, the tip of the suppression section 27 does not unintentionally come into contact with the inner surface of the protector 3. In this way, in the structure of this example, it is possible to secure a wide bending space for the suppression section 27, which is also highly effective in this respect.

[0032] Also, in this example, the protector 3 is structured to have a suppression section 27. That is, a member (suppression section 27) that suppresses the tilt is provided on a member (protector 3) that tends to tilt when a load is applied. Therefore, the tilt of the protector 3 can be suppressed by the simple configuration of providing the suppression section 27 on the protector 3. In this way, it is possible to provide a protector 3 that is integrally provided with the suppression section 27.

[0033] According to the protector 3 of the above embodiment, the following effects can be obtained. (1) The protector 3 includes a protector body 9, a fixing portion 21, and a suppressing portion 27. The harness 2 passes through the protector body 9, and at least a portion of the protector body 9 is disposed in the space 12 between the opposing first article 10 and second article 11. The fixing portion 21 fixes the protector body 9 to the first article 10. The suppressing portion 27 suppresses tilting of the protector body 9 with the fixing portion 21 as a base point.

[0034] According to the configuration of this example, when a load is applied to the protector 3 from above, the protector 3 may tilt around the fixed portion 21, but the suppressing portion 27 provided on the protector 3 makes it possible to make the protector 3 less likely to tilt. If the protector 3 tilts, the harness 2 may be pulled and subjected to a load at the opening 17 through which the harness 2 passes in the protector 3, but with the configuration of this example, this situation is less likely to occur. Therefore, the harness 2 can be protected.

[0035] (2) Since the protector 3 is made difficult to tilt, it is possible to make it difficult for the protector 3 to tilt and come into contact with the first article 10. Therefore, it is possible to make it difficult for the protector 3 to tilt and come into contact with the first article 10, which would cause a hitting sound.

[0036] (3) The protector body 9 is formed in a shape that crosses the columnar first article 10. With this configuration, the space around the first article 10 can be effectively utilized to ensure a path for the harness 2.

[0037] (4) A plurality of suppression parts 27 are provided. According to this configuration, even if a load applied to protector 3 from above causes protector 3 to tilt about fixing part 21, the load is dispersed by the plurality of suppression parts 27, making it possible to prevent protector 3 from tilting.

[0038] (5) The protector body 9 includes a first harness insertion portion 14 disposed opposite an upper surface of a columnar first article 10, and a second harness insertion portion 15 disposed opposite a side surface of the first article 10. The fixing portion 21 is disposed on a rear surface 25 of the first harness insertion portion 14. The suppressing portion 27 is disposed on an inner surface 28 of the second harness insertion portion 15. With this configuration, even if a load applied to the protector 3 from above causes the protector 3 to tilt about the fixing portion 21, the suppressing portion 27 abutting against the side surface of the first article 10 can firmly hold the position of the protector 3.

[0039] (6) The first harness insertion portion 14 includes a pair of arms 16 disposed in the space 12. The second harness insertion portion 15 is formed in a shape that connects the pair of arms 16. The fixing portion 21 is disposed on the arms 16. With this configuration, even if an obstacle is present at the midpoint between the pair of arms 16, the harness 2 can be detouring by the protector 3 and returned to the original wiring route that would be taken if no detouring were performed.

[0040] (7) The suppression portion 27 suppresses the inclination of the protector body 9 by bending the base end with the tip as a fulcrum. With this configuration, it is possible to form the shape of the suppression portion 27 such that no member is present at the tip of the suppression portion 27. This makes it possible to prevent the tip of the suppression portion 27 from interfering with the surrounding wall surface (for example, the inner surface of the protector 3) when the suppression portion 27 bends.

[0041] (8) The suppression portion 27 is a spring portion that applies a load for suppressing tilt to the protector body 9 by a bending reaction force. According to this configuration, the suppression portion 27 can be configured with a simple spring structure.

[0042] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs. The fixing portion 21 may be structured such that, for example, a protrusion provided on the first article 10 is inserted into a recess provided on the protector 3 to fix the first article 10 in place.

[0043] The fixing portion 21 is not limited to an insert-type clip, and may be of any shape that can fix the protector 3 to the first article 10. The suppression portion 27 is not limited to being disposed on the inner surface 28 of the protector 3, and may be disposed on the rear surface 25 of the protector body 9, for example.

[0044] The suppression portion 27 may be disposed on both the rear surface 25 and the inner surface 28 of the protector 3 . The location of the suppression unit 27 can be freely set as appropriate. The number of suppressing units 27 is not limited to a plurality, and may be, for example, one.

[0045] The suppression portion 27 is not limited to a spring portion (leaf spring), and may be of any shape that can apply a reaction force against the tilt to the protector 3. The cross-sectional shapes of the first harness insertion portion 14 and the second harness insertion portion 15 are not limited to a flat shape, and may be changed to other shapes, such as a circular or rectangular cross-sectional shape.

[0046] The shape of the protector body 9 is not limited to the U-shape and may be changed to another shape, such as an L-shape. The protector body 9 may have a shape having only one arm portion 16, for example.

[0047] The first item 10 is not limited to a cross member, but may be another member, such as a vehicle body frame. The second item 11 is not limited to the interior floor surface of the vehicle, but may be, for example, any member on which the weight of a vehicle user is applied.

[0048] The space 12 in which the protector 3 is disposed is not limited to the gap between the first item 10 and the second item 11, but may be any gap that occurs between two components of a vehicle. The housing structure of the protector 3 is not limited to a structure in which the two housings 4 and 5 are assembled together. For example, the protector 3 may be made up of three or more housing members, or may have only one housing member.

[0049] The harness 2 is not limited to a single electric wire, but may be a group of electric wires in which a plurality of electric wires are bundled together. Also, the harness 2 may be an electric wire covered with a covering material. Although the present disclosure has been described with reference to the embodiment, it is understood that the present disclosure is not limited to the embodiment or structure. The present disclosure also includes various modifications and modifications within the scope of equivalents. In addition, various combinations and forms, as well as other combinations and forms including only one element, more than one element, or less than one element, are also within the scope and concept of the present disclosure.

[0050] Next, the technical ideas that can be understood from the above embodiment and modified examples will be described. (A) A protector comprising a first arm through which a harness is passed, a second arm arranged opposite the first arm through which the harness is passed, and a connecting part formed in a shape connecting the first arm and the second arm and through which the harness is passed. Note that the first arm and the second arm correspond to the first harness insertion part, and the connecting part corresponds to the second harness insertion part.

[0051] However, there are cases where an obstacle is present on the route along which the harness is routed. In such cases, it may be necessary to make major design changes, such as changing the route of the harness or changing the location of the obstacle.

[0052] On the other hand, according to the configuration of this example, when an obstacle is present on the route along which the harness is routed, the protector is disposed so as to surround the obstacle with the first arm, the second arm, and the connecting part, and the inside of the protector is made the route of the harness. This makes it possible to provide a detour route to avoid the obstacle, thereby improving the degree of freedom in routeing the harness.

[0053] (ii) A protector according to the above technical idea (i), which includes a fixing part that is fixed to an article. According to this configuration, the protector can be fixed to the article by the fixing part, so that the protector can be held in a predetermined mounting position.

[0054] (C) In the technical idea (B), the fixing portion is disposed on the rear surface of each of the first arm and the second arm. With this configuration, the fixing portion on the rear surface of the first arm and the fixing portion on the rear surface of the second arm can firmly fix the protector to an article.

[0055] (D) In ​​the technical ideas (A) to (C), the connecting portion is a protector that extends on a plane that intersects with the plane on which the first arm portion and the second arm portion extend. With this configuration, it is possible to arrange the protector along the top and side surfaces of the article. Therefore, even when storage space is limited, it is possible to arrange the protector.

[0056] (E) In the technical ideas (A) to (D), the first arm and the second arm are formed to have a rectangular cross section (longitudinal cross section) so that they can be placed in a gap. This configuration allows the protector to have a thin shape. Therefore, even when storage space is limited, the protector can be placed.

[0057] (F) A protector according to the above technical ideas (A) to (E), in which the openings of the first arm and the second arm are provided with guide parts for guiding the harness through the openings. With this configuration, the guide parts make it easier to pass the harness through the inside of the protector. [Explanation of symbols]
