Description

[Technical Field]

[0001] The present invention relates to a path control member. [Background technology]

[0002] Conventionally, path-regulating members have been proposed to regulate bending of electric wires. Patent Document 1 discloses a path-regulating member that covers an area greater than half of the circumferential direction of an outer periphery of an outer periphery member such as a corrugated tube that covers the outer periphery of an electric wire, extends along the length of the outer periphery member, and regulates the path along which the electric wire is routed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-69307 Summary of the Invention [Problem to be solved by the invention]

[0004] However, since the above-mentioned path regulating member cannot cover the entire circumferential area of the electric wire, it cannot be directly attached to the electric wire, and is attached to the electric wire after using an outer member such as a corrugated tube as described above. Therefore, the above-mentioned path regulating member tends to have an increased number of parts, and there is also a risk that the manufacturing process will become complicated and the manufacturing costs will increase. Furthermore, the above-mentioned path regulating member can only be attached to electric wires with a predetermined diameter, and it is necessary to manufacture the path regulating member according to the diameter of the electric wire, which is likely to increase the manufacturing costs.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and its purpose is to provide a path control member that controls the path along which an electric wire is routed with a simple structure while minimizing an increase in the number of parts. [Means for solving the problem]

[0006] In order to achieve the above object, the path regulating member according to the present invention is characterized as follows. A path regulating member for regulating a path through which an electric wire is routed, A sheet-like first sheet member in which a first ridge portion and a first valley portion extending in the axial direction of the electric wire are alternately connected in a direction intersecting the axial direction on the outer surface, and which is wound so as to cover a part of the outer periphery of a predetermined portion of the electric wire; A sheet-like second sheet member in which a second ridge portion and a second valley portion extending in the axial direction are alternately connected in the intersecting direction on the outer surface, and which is wound so as to cover the outer periphery of another predetermined portion of the electric wire and is fitted to the first sheet member; Comprising: The second sheet member has: A fitting extension portion that extends toward the first sheet member in the axial direction and is fitted to the outer surface of the first sheet member, It is a path regulating member.

Advantages of the Invention

[0007] According to the present invention, a first ridge portion and a first valley portion extending in the axial direction are alternately connected in the intersecting direction on the outer surface of the first sheet member, and a second ridge portion and a second valley portion extending in the axial direction are alternately connected in the intersecting direction on the outer surface of the second sheet member, so that it is possible to regulate the path through which the electric wire is routed, including the regulation of the bending of the electric wire. Further, since the outer surfaces of the first sheet member and the second sheet member are configured as described above, by adjusting the interval between adjacent ridge portions, for example, when the electric wire is routed under the floor of a vehicle such as an automobile, it is possible to cope with chipping such as flying stones. And since the first sheet member and the second sheet member are configured to be simply wound around the electric wire, the number of parts can be reduced compared to the conventional one provided with an exterior member and a path regulating member. Thus, according to the present invention, it is possible to regulate the path through which the electric wire is routed with a simple structure.

[0008] The above is a brief description of the present invention. Further, the details of the present invention will be further clarified by reading through the embodiments for carrying out the invention described below (hereinafter referred to as "embodiments") with reference to the accompanying drawings.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, with reference to the drawings, a path restricting member 1 according to an embodiment of the present invention will be described.

[0011] Hereinafter, for convenience of explanation, as shown in FIG. 1 and the like, "front", "rear", "left", "right", "upper" and "lower" are defined. The "front-rear direction", "left-right direction" and "upper-lower direction" are orthogonal to each other. Note that the front-rear direction corresponds to the "axial direction" of the present invention. Also, in FIGS. 3 to 4, the left-right direction corresponds to the "crossing direction" of the present invention, and the upper-lower direction corresponds to the "thickness direction" of the present invention.

[0012] As shown in FIGS. 1 to 2, the path regulating member 1 is wound (mounted) so as to cover the outer periphery of the electric wire W, and constitutes a wire harness WH together with the electric wire W. The wire harness WH connects between a plurality of vehicle devices (not shown) mounted on a vehicle such as an electric vehicle, and is routed so as to pass under the floor of the vehicle or the like. The path regulating member 1 regulates the path along which the electric wire W is routed, including regulating the bending of the electric wire W, in this type of wire harness WH.

[0013] As shown in FIGS. 3 to 4, the path regulating member 1 includes a sheet-like first sheet member 10 and a sheet-like second sheet member 20 fitted to the first sheet member 10. Hereinafter, the first sheet member 10 and the second sheet member 20 constituting the path regulating member 1 will be described in order.

[0014] First, the first sheet member 10 will be described. The first sheet member 10 is wound so as to cover a part of the outer periphery of a predetermined portion of the electric wire W, and in this example, it is the main protective sheet that protects most of the predetermined portion.

[0015] As shown in FIGS. 3 to 4, the first sheet member 10 is formed in a substantially rectangular shape that is long in the front-rear direction in a top view, and on its outer surface (the upper surface in FIGS. 3 to 4), first ridge portions 11 and first valley portions 12 extending in the front-rear direction are alternately connected in the left-right direction. On the other hand, the inner surface (the lower surface in FIGS. 3 to 4) of the first sheet member 10 that contacts the electric wire W is flat.

[0016] As shown in FIG. 4, a first hook portion 13 that protrudes downward is provided at the left end of the first sheet member 10. The first hook portion 13 is locked so as to be hooked on one of the first ridge portions 11 in a state where the mounting of the first sheet member 10 to the electric wire W is completed (that is, the first sheet member 10 is wound around the electric wire W).

[0017] At substantially the center in the front-back direction and left-right direction of the first sheet member 10, as shown in FIG. 4, a plurality (a pair in this example) of first through holes 14 penetrating in the up-down direction are provided. When the first sheet member 10 is attached to the electric wire W, a bundling member (not shown, for example, a band or the like) for bundling the electric wire W to the first sheet member 10 is to be inserted through the first through holes 14.

[0018] Next, the second sheet member 20 will be described. The second sheet member 20 is wound so as to cover the outer periphery of other parts at a predetermined position of the electric wire W. In this example, it is a sub (additional) protective sheet for protecting a small part at a predetermined position.

[0019] As shown in FIGS. 3 to 4, the second sheet member 20 has a main body portion 20a formed in a substantially rectangular shape that is long in the front-back direction in a top view. On the outer surface (the upper surface in FIGS. 3 to 4) of the main body portion 20a, second ridge portions 21 and second valley portions 22 extending in the front-back direction are alternately connected in the left-right direction. On the other hand, the inner surface (the lower surface in FIGS. 3 to 4) of the first sheet member 10 that contacts the electric wire W is flat.

[0020] In this example, since the second sheet member 20 is a sub (additional) protective sheet, the length of the main body portion 20a in the front-back direction is formed shorter than the length of the first sheet member 10 in the front-back direction.

[0021] At the left end of the main body portion 20a of the second sheet member 20, as shown in FIG. 4, a second hook portion 23 protruding downward is provided. The second hook portion 23 is locked so as to be hooked on one of the second ridge portions 21 in a state where the second sheet member 20 is completely attached to the electric wire W (that is, the second sheet member 20 is wound around the electric wire W).

[0022] At substantially the center in the front-rear direction and the left-right direction of the main body portion 20a of the second sheet member 20, as shown in FIG. 4, a plurality (a pair in this example) of second through holes 24 penetrating in the vertical direction are provided. When the second sheet member 20 is attached to the electric wire W, a binding member (not shown, such as a band) for binding the electric wire W to the second sheet member 20 is to be inserted through the second through holes 24.

[0023] In a substantially central region in the left-right direction of the main body portion 20a of the second sheet member 20, as shown in FIGS. 1, 3, and 4, a fitting extension portion 25 that extends forward (toward the first sheet member 10) and is fitted to the outer surface of the first sheet member 10 is provided. As particularly shown in FIG. 2, the fitting extension portion 25 has third ridge portions 26 and third valley portions 27 that extend in the front-rear direction and are alternately connected in the left-right direction corresponding to the first ridge portion 11 and the first valley portion 12, and is formed in an uneven shape when viewed in the front-rear direction.

[0024] It should be noted that the third ridge portion 26 becomes a valley when viewed from the inner surface side, and the third valley portion 27 becomes a ridge when viewed from the inner surface side (see FIG. 2). Therefore, when the fitting extension portion 25 is fitted to the outer surface of the first sheet member 10, the third ridge portion 26 is fitted into the first ridge portion 11, and the third valley portion 27 is fitted into the first valley portion 12. In this way, by fitting the third ridge portion 26 and the third valley portion 27 of the fitting extension portion 25 into the first ridge portion 11 and the first valley portion 12, respectively, the second sheet member 20 is fitted to the first sheet member 10.

[0025] The first sheet member 10 and the second sheet member 20 that constitute the path restricting member 1 have been described above. Next, an example of a method (wrapping) of attaching the path restricting member 1 to the electric wire W will be described.

[0026] First, the first sheet member 10 is disposed at a corresponding position of the electric wire W, and a binding member is inserted through the first through hole 14 to bind the electric wire W to the first sheet member 10. Then, the first sheet member 10 is wound around the outer circumference of the electric wire W, and the first hook portion 13 is hooked and locked to one of the first ridge portions 11. Thereby, the first sheet member 10 is attached to the electric wire W.

[0027] Next, the second sheet member 20 is disposed at a corresponding position of the electric wire W. With the fitting extension portion 25 fitted to the outer surface of the first sheet member 10, a bundling member is inserted through the second through hole 24 to bundle the electric wire W to the second sheet member 20. Thereafter, the second sheet member 20 is wound around the outer periphery of the electric wire W, and the second hook portion 23 is hooked and locked to one of the second mountain portions 21. Thereby, the second sheet member 20 is attached to the electric wire W.

[0028] As a result, the path restricting member 1 is attached to the electric wire W, and the wire harness WH shown in FIG. 1 is completed. An example of a method (wrapping) of attaching the path restricting member 1 to the electric wire W has been described.

[0029] In addition, as another example of the method of attaching the path restricting member 1 to the electric wire W, for example, first, after fitting the first sheet member 10 to the second sheet member 20, the first sheet member 10 and the second sheet member 20 may be collectively wound around the electric wire W. Further, in the method of attaching the path restricting member 1 to the electric wire W, the order of the steps of bundling the electric wire W to each sheet member (referring to the first sheet member 10 and the second sheet member 20) and the step of winding each sheet member around the electric wire W does not matter. The order of these steps is appropriately determined.

[0030] By the way, as described above, the electric wire W with the path restricting member 1 attached is transported to an automobile manufacturing factory or the like for mounting on a vehicle, for example. At this time, the electric wire W with the path restricting member 1 will be packed in a packing material such as cardboard. Generally, in an electric wire with a path restricting member, since the bending of the electric wire is restricted, it is necessary to prepare a large packing material or attach the path restricting member to the electric wire at an automobile manufacturing factory or the like. However, in the case of the path restricting member 1 of the present embodiment, as shown in FIG. 5, since the intended fitting release between the first sheet member 10 and the second sheet member 20 can be easily performed, the electric wire W can be packed in a bent state, so that the packing operation of the electric wire W with the path restricting member 1 becomes easy.

[0031] As described above, according to the present embodiment, the first mountain portions 11 and the first valley portions 12 extending in the front-rear direction are alternately connected to the outer surface of the first sheet member 10, and the second mountain portions 21 and the second valley portions 22 extending in the front-rear direction are alternately connected to the outer surface of the second sheet member 20, so that the path through which the electric wire W is routed, including the restriction of the bending of the electric wire W, can be restricted. Further, since the outer surfaces of the first sheet member 10 and the second sheet member 20 are configured as described above, by adjusting the interval between adjacent mountain portions, it is possible to cope with chipping such as flying stones. And since the first sheet member 10 and the second sheet member 20 are configured to be simply wound around the electric wire W, the number of parts can be reduced as compared with the conventional one provided with an exterior member and a path restricting member. Thus, according to the present embodiment, the path through which the electric wire W is routed can be restricted with a simple structure.

[0032] In addition, since the first sheet member 10 and the second sheet member 20 may be simply wound around the electric wire W as described above, the workability of attaching the path restricting member 1 to the electric wire W is excellent, and it is possible to cope with electric wires W having different diameters.

[0033] Furthermore, according to the present embodiment, the second sheet member 20 is fitted to the first sheet member 10 by fitting the third mountain portion 26 and the third valley portion 27 of the fitting extension portion 25 into the first mountain portion 11 and the first valley portion 12 of the first sheet member 10, respectively. Thus, according to the above configuration, the first sheet member 10 and the second sheet member 20 can be fitted with a simple structure, and in addition, as described above, the packaging of the electric wire W with the path restricting member 1 becomes easy.

[0034] Furthermore, according to the present embodiment, by providing the first hook portion 13 on the first sheet member 10 and the second hook portion 23 on the second sheet member 20, the attachment of the path restricting member 1 to the electric wire W becomes easy.

[0035] Furthermore, according to the present embodiment, by providing the first through hole 14 in the first sheet member 10 and the second through hole 24 in the second sheet member 20, the electric wire W can be fixed to each sheet member, so that the friction and wear of the electric wire W due to vibration can be suppressed.

[0036] Note that the present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. In addition, the material, shape, dimensions, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.

[0037] In the above embodiment, the path restricting member 1 is configured to include the first sheet member 10 and the second sheet member 20. However, for example, only one of the first sheet member 10 and the second sheet member 20 may be used as the path restricting member 1.
