Description

Technical Field

[0001] This disclosure relates to composite wire harnesses. Background Technology

[0002] For example, Patent Document 1 discloses a composite wiring harness for vehicles. This composite wiring harness includes a first wiring harness consisting of a first wire passing through a metal tube, and a second wiring harness consisting of a second wire passing through a corrugated tube made of synthetic resin. In the first wiring harness, the metal tube covers most of the length of the first wire, protecting it from damage by flying objects, water droplets, etc. Furthermore, the metal tube restricts the wiring path of the first wire. The second wiring harness is arranged side-by-side with the metal tube of the first wiring harness and is connected to the metal tube. Thus, the wiring path of the second wire of the second wiring harness is also restricted by the metal tube.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2012-197034 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] In the wire harness described above, the first wire is protected by a metal conduit that restricts the path of the first wire. Here, for the sake of weight reduction and miniaturization, it is desirable to have a small diameter for the metal conduit. However, when the diameter of the metal conduit is reduced, it is sometimes impossible for components such as connectors installed at the ends of the first wire along its length to pass through the metal conduit. Therefore, it is necessary to pass the first wire through the metal conduit before installing components such as connectors at the ends of the first wire along its length, which can improve the ease of assembly of the composite wire harness.

[0008] Therefore, the aim is to provide composite wire harnesses that improve assembly workability.

[0009] Solution for solving the problem

[0010] The composite wire harness disclosed herein comprises: a first wire harness having a first wire and a first outer casing member covering the first wire; a second wire harness having a second wire and a second outer casing member covering the second wire; and a first path limiting member mounted on the first wire harness and the second wire harness, the first wire harness and the second wire harness being arranged side by side, the first path limiting member having a first body portion and a first insertion port, the first body portion covering a portion of the outer periphery of the first outer casing member and the second outer casing member, the first insertion port being formed by a first end portion and a second end portion serving as two circumferential ends of the first body portion, the first insertion port being an opening extending in the longitudinal direction of the first path limiting member and extending throughout the entire length of the first path limiting member, the first path limiting member holding both the first wire harness and the second wire harness together.

[0026] [Description of embodiments of this disclosure]

[0027] First, embodiments of this disclosure will be described.

[0028] The composite wire harness disclosed herein,

[0029] [1] The device comprises: a first wire harness having a first wire and a first outer member covering the first wire; a second wire harness having a second wire and a second outer member covering the second wire; and a first path limiting member mounted on the first wire harness and the second wire harness, the first wire harness and the second wire harness being arranged side by side, the first path limiting member having a first body portion and a first insertion port, the first body portion covering a portion of the outer periphery of the first outer member and the second outer member, the first insertion port being formed by a first end portion and a second end portion serving as two circumferential ends of the first body portion, the first insertion port being an opening extending in the length direction of the first path limiting member and extending throughout the entire length of the first path limiting member, the first path limiting member holding the first wire harness and the second wire harness together.

[0030] According to this structure, after end processing such as installing connectors at the ends of the first and second wires along their respective length directions, a first path limiting member can be installed on the first and second outer components from the first insertion port. This allows the first path limiting member to be installed after the first and second outer components, thus improving the assembly workability of the composite wire harness.

[0031] In addition, the first path limiting member also holds the first outer component and the second outer component, limiting the paths of the first and second wire harnesses. That is, the paths of multiple wire harnesses can be limited by one first path limiting member, thus helping to reduce the number of components in the composite wire harness.

[0032] [2] The first path limiting member is harder than the first outer component and the second outer component.

[0033] According to this structure, the paths of the first and second wire harnesses can be more firmly restricted by a rigid first path limiting member.

[0034] [3] The first path limiting member has a first protrusion and a second protrusion, the first protrusion protruding from the inner surface of the first end and contacting the outer surface of the first outer member, and the second protrusion protruding from the inner surface of the second end and contacting the outer surface of the second outer member.

[0035] According to this structure, the first and second protrusions can be used to prevent the first and second outer components from falling off the first path limiting member through the first insertion port. This prevents accidental detachment of the first path limiting member, thus further improving the assembly workability of the composite wire harness.

[0036] [4] The first path limiting member has a partition protruding from the first main body toward the first insertion port, the partition being located between the first outer member and the second outer member.

[0037] According to this structure, in the first path limiting member, the division between the portion where the first outer component is disposed and the portion where the second outer component is disposed is made by a partition. Therefore, the workability of assembling the first outer component and the second outer component in the first path limiting member can be improved.

[0038] [5] The top end of the partition has a first top end and a second top end, the first top end covering a portion of the outer periphery of the first outer component, and the second top end extending in a direction different from the first top end and covering a portion of the outer periphery of the second outer component.

[0039] According to this structure, the top end of the partition is formed in a bifurcated manner, dividing into a first top end and a second top end. Therefore, for example, the length of the first top end and the length of the second top end can be set independently. Thus, the outer periphery of the first outer component covered by the first top end and the outer periphery of the second outer component covered by the second top end can be adjusted independently.

[0040] [6] The partition includes a first protrusion protruding from the inner surface of the first top end toward the first outer member and a second protrusion protruding from the inner surface of the second top end toward the second outer member.

[0041] According to this structure, the partition has a first protrusion protruding from the inner surface of the first top end toward the first outer member. This first protrusion can prevent the first outer member from detaching from the first path limiting member. Furthermore, the partition has a second protrusion protruding from the inner surface of the second top end toward the second outer member. This second protrusion can prevent the second outer member from detaching from the first path limiting member.

[0042] [7] A second path limiting member is provided and installed on the outer periphery of the first outer component. The second path limiting member has a second body portion and a second insertion port. The second body portion covers a portion of the outer periphery of the first outer component. The second insertion port is formed by a third end portion and a fourth end portion, which are the two circumferential ends of the second body portion. The second insertion port is an opening extending in the length direction of the second path limiting member and extends throughout the entire length of the second path limiting member. The second path limiting member is disposed between the outer peripheral surface of the first outer component and the first path limiting member.

[0043] According to this structure, a second path-limiting member is installed inside the first outer component, thus providing more appropriate protection for the first outer component against damage from flying objects. This, in turn, contributes to improved durability of the composite wiring harness.

[0044] In addition, the paths of the first and second wire harnesses can be more appropriately restricted using the first path restriction member and the second path restriction member.

[0045] In addition, because the first outer component is double-covered by the first path limiting component and the second path limiting component, heat transfer from the outside to the first outer component can be more effectively suppressed.

[0046] Furthermore, the second insertion port of the second path limiting member is an opening extending along the length of the second path limiting member and extending throughout its entire length. Therefore, after end processing such as installing a connector at the end of the first wire along its length, the second path limiting member can be installed onto the first outer component through the second insertion port. This allows the second path limiting member to be installed after the first outer component, thus improving the ease of assembly of the composite wire harness.

[0047] [8] The second path limiting member is more rigid than the first outer component.

[0048] According to this structure, the path of the first harness can be more firmly restricted by a rigid second path limiting member.

[0049] [9] The second path limiting member is longer than the first path limiting member in the length direction of the first wire harness.

[0050] According to this structure, for example, when the first wire harness requires path restriction in a section longer than the second wire harness, instead of lengthening the first path restriction member, the second path restriction member mounted on the first outer component is lengthened to correspond to this, thereby restricting only the parts that require path restriction. That is, the first path restriction member does not need to be extended to the section of the second wire harness that does not require path restriction. As a result, it is possible to minimize the size of the first path restriction member, and thus contribute to the weight reduction of the composite wire harness.

[0051]

[10] The second path limiting member has a third protrusion that protrudes from the inner surface of at least one of the third end and the fourth end and contacts the outer surface of the first outer member.

[0052] According to this structure, the third protrusion can be used to prevent the first outer component from falling off the second path limiting component through the second insertion port. This prevents accidental detachment of the second path limiting component, thus further improving the assembly workability of the composite wire harness.

[0053]

[11] A third path limiting member is provided and installed on the first path limiting member. The third path limiting member has a third main body and a third insertion port. The third main body covers the outer periphery of the first path limiting member. The third insertion port is formed by a fifth end and a sixth end, which are the two circumferential ends of the third main body. The third insertion port is an opening that extends in the length direction of the third path limiting member and extends throughout the entire length of the third path limiting member.

[0054] According to this structure, a third path-limiting member is provided outside the first path-limiting member, thus providing more adequate protection for the first and second outer components against damage from flying objects. This, in turn, contributes to improved durability of the composite wiring harness.

[0055] In addition, the paths of the first and second wire harnesses can be more appropriately restricted using the first and third path restriction members.

[0056] Furthermore, since the first and second outer components are double-covered by the first and third path limiting components, heat transfer from the outside to the first and second outer components can be more effectively suppressed.

[0057] Furthermore, the third insertion port of the third path limiting member is an opening extending along the length of the third path limiting member and extending along its entire length. Therefore, the third path limiting member can be installed laterally through the third insertion port, thus improving the ease of assembly of the composite wire harness.

[0058]

[12] The third path limiting member is harder than the first outer component and the second outer component.

[0059] According to this structure, the paths of the first and second wire harnesses can be more firmly restricted by a rigid third path limiting member.

[0060]

[13] The third path limiting member is shorter than the first path limiting member in the length direction of the first path limiting member.

[0061] According to this structure, the third path limiting member can be provided only at the locations in the composite wire harness where it is required. Therefore, the third path limiting member does not need to extend to locations where it is not required, which helps to miniaturize the third path limiting member and thus contributes to the weight reduction of the composite wire harness.

[0062]

[14] The third path restriction component is made of metal.

[0063] According to this structure, the third path limiting member, which is made of metal material, can effectively isolate heat transferred from the outside to the first and second outer components.

[0064]

[15] The first path limiting member is made of synthetic resin material.

[0065] According to this structure, the first path limiting member, disposed between the first and second outer components and the third path limiting member, is made of synthetic resin. Therefore, the synthetic resin first path limiting member can suppress contact between the metal third path limiting member and the first and second outer components. As a result, wear on the first and second outer components caused by contact with the metal third path limiting member can be suppressed.

[0066]

[16] The third path limiting member is made of colored synthetic resin material.

[0067] According to this structure, the third path limiting member can be set to a desired color even if the surface is not coated. For example, when at least one of the first and second wires is a high-voltage wire, by setting the color of the first path limiting member to a color that allows the operator to identify that at least one of the first and second wires is a high-voltage wire, attention can be drawn to prevent the operator from mistakenly cutting the composite wire harness that includes the high-voltage wire.

[0068]

[17] The first path limiting member is made of a colored synthetic resin material, and the third path limiting member is made of a synthetic resin material of the same color as the first path limiting member.

[0069] According to this structure, even without surface coating, the first path limiting member and the third path limiting member can be set to a desired color. For example, when at least one of the first wire and the second wire is a high-voltage wire, by setting the color of the first path limiting member to a color that allows the operator to identify that at least one of the first wire and the second wire is a high-voltage wire, attention can be drawn to prevent the operator from mistakenly cutting the composite wire harness that includes the high-voltage wire.

[0070]

[18] The second path limiting member is made of colored synthetic resin material.

[0071] According to this structure, the second path limiting member can be set to a desired color even if the surface is not painted. For example, when the first wire is a high-voltage wire, by setting the color of the second path limiting member to a color that the operator can identify as a high-voltage wire, it can draw the operator's attention and prevent the operator from mistakenly cutting the composite wire harness that includes the high-voltage wire.

[0072]

[19] The first path limiting member is made of a colored synthetic resin material, and the second path limiting member is made of a synthetic resin material of the same color as the first path limiting member.

[0073] According to this structure, even without surface coating, the first path limiting member and the second path limiting member can be set to a desired color. For example, when the first wire is a high-voltage wire, by setting the colors of the first path limiting member and the second path limiting member to colors that allow the operator to identify that the first wire is a high-voltage wire, it can draw the operator's attention and prevent the operator from mistakenly cutting the first wire harness containing the high-voltage wire.

[0074]

[20] The first path limiting member is made of colored synthetic resin material.

[0075] According to this structure, the first path limiting member can be set to a desired color even if the surface is not coated. For example, when at least one of the first wire and the second wire is a high-voltage wire, by setting the color of the first path limiting member to a color that allows the operator to identify that at least one of the first wire and the second wire is a high-voltage wire, attention can be drawn to prevent the operator from mistakenly cutting the composite wire harness that includes the high-voltage wire.

[0076]

[21] The first path restriction member is made of metal.

[0077] According to this structure, the first path limiting member made of metallic material can effectively isolate heat transferred from the outside to the first outer component and the second outer component.

[0078]

[22] The first outer component is larger than the second outer component.

[0079] According to this structure, the first path limiting member, together with the first and second outer components which have different external dimensions, restricts the paths of the first and second wire harnesses. That is, even when the first and second outer components have different external dimensions, the paths of multiple wire harnesses can be restricted by a single first path limiting member. This helps to reduce the number of components in a composite wire harness.

[0080]

[23] The first wire harness has two first wires, and the second wire harness has three second wires. The two first wires are wires that constitute a DC circuit, and the three second wires are wires that constitute a three-phase circuit.

[0081] According to this structure, a first path limiting member can be used to restrict the path of a first wiring harness having two first wires constituting a DC circuit and a second wiring harness having three second wires constituting a three-phase circuit. Therefore, a first path limiting member can be used to restrict the path of the first and second wiring harnesses used, for example, in a four-wheel drive vehicle. This contributes to reducing the number of components in a composite wiring harness.

[0082] [Details of the embodiments of this disclosure]

[0083] Specific examples of the composite wire harness of this disclosure are described below with reference to the accompanying drawings. In the drawings, for ease of explanation, sometimes a portion of the structure is shown enlarged or simplified. Furthermore, the dimensional ratios of the various parts sometimes differ in the drawings. Additionally, the terms "parallel" and "orthogonal" in this specification include not only cases where they are strictly parallel or orthogonal, but also cases where they are substantially parallel or orthogonal to the extent that they serve the function and effect of this embodiment.

[0084] Furthermore, the term "cylindrical" as used in this specification refers not only to a cylindrical shape with a continuous circumferential wall, but also to a shape formed by combining multiple components, or a shape with a notch in a portion of the circumference, such as a C-shape. Additionally, the shape of "cylindrical" includes circles, ellipses, and polygons with pointed or rounded corners. Furthermore, the term "ring-shaped" as used in this specification sometimes refers to any structure forming a ring, a continuous shape without ends, or a generally ring-shaped structure with a gap, such as a C-shape. Additionally, the shape of "ring-shaped" includes circles, ellipses, and polygons with pointed or rounded corners, but is not limited to these.

[0085] <First Implementation>

[0086] The first embodiment of the composite wire harness will be described below.

[0087] Figure 1The composite wiring harness 10 shown connects, for example, machines installed in vehicle V to each other. The composite wiring harness 10 is configured in vehicle V, for example, with its middle portion along its length passing under the floor of vehicle V or outside the vehicle body.

[0088] The composite wire harness 10 includes a first wire harness 11 and a second wire harness 12 arranged side by side. The first wire harness 11 and the second wire harness 12 are arranged, for example, in a parallel manner. Furthermore, the composite wire harness 10 includes... Figure 2 The first path limiting member 40 is shown. The first path limiting member 40 together holds the first harness 11 and the second harness 12. Furthermore, in... Figure 1 The illustration of the first path restriction component 40 is omitted.

[0089] like Figure 1 As shown, the first wiring harness 11 electrically connects the first unit M1 and the second unit M2, which are installed in the vehicle V, to each other. As an example of the first unit M1 and the second unit M2, the first unit M1 is a high-voltage battery located at the rear of the vehicle V, and the second unit M2 is an inverter located at the front of the vehicle V. The first unit M1, as a high-voltage battery, is, for example, a battery capable of supplying voltages of 100 volts or higher. The second unit M2, as an inverter, is connected to an electric motor (not shown) that serves as the power source for the drive wheels of the vehicle. The inverter generates alternating current from the direct current (DC) power of the high-voltage battery and supplies this AC power to the electric motor. The first wiring harness 11 is a high-voltage wiring harness capable of exchanging high voltage between the high-voltage battery and the inverter.

[0090] The second wiring harness 12 electrically connects the third machine M3 and the fourth machine M4, which are installed in the vehicle V, to each other. As an example of the third machine M3 and the fourth machine M4, the third machine M3 is a low-voltage battery located at the rear of the vehicle V, and the fourth machine M4 is a relay box located at the front of the vehicle V. The fourth machine M4, acting as a relay box, distributes the voltage of the low-voltage battery to various machines installed in the vehicle V. The second wiring harness 12 is a low-voltage wiring harness that corresponds to the supply current of the low-voltage battery. Furthermore, both the first wiring harness 11 and the second wiring harness 12 are formed in a two-dimensional or three-dimensional shape according to the wiring path.

[0091] (Structure of the first harness 11)

[0092] like Figure 3 As shown, the first wiring harness 11 has a first wire 21 and a first outer casing 22. For example, multiple first wires 21 are provided. The first outer casing 22 is, for example, cylindrical. The first outer casing 22, for example, surrounds multiple first wires 21 together. Furthermore, one end of the first wire 21 is connected to the first machine M1, and the other end of the first wire 21 is connected to the second machine M2. The first wire 21 is a high-voltage wire capable of handling high voltage and high current.

[0093] The first wire 21 has a first core wire 23 and a first insulating covering portion 24 that encloses the outer periphery of the first core wire 23. The first core wire 23 is, for example, made of a flexible conductor that can be easily bent. Furthermore, as an example of such a flexible conductor, it is a stranded wire made of multiple metal wires twisted together. As the material of the first core wire 23, for example, copper-based, aluminum-based, and other metal materials can be used.

[0094] The first insulating cover 24, for example, covers the entire outer periphery of the first core wire 23. The first insulating cover 24 is made of an insulating material such as synthetic resin. The first insulating cover 24 can be formed, for example, by extrusion molding of the first core wire 23.

[0095] The first outer casing 22 is generally elongated cylindrical. A first wire 21 is inserted into the internal space of the first outer casing 22. The first outer casing 22 protects the first wire 21 from damage by, for example, flying objects or water droplets.

[0096] like Figure 2 As shown, the first outer component 22 is, for example, a corrugated tube made of synthetic resin. The first outer component 22, being a corrugated tube, is formed with a corrugated shape whose diameter varies repeatedly along its length. That is, the first outer component 22 has recesses 22a and protrusions 22b that are alternately connected along its length. Each of the recesses 22a and protrusions 22b is, for example, formed into a ring that wraps around the circumference of the first outer component 22. The first outer component 22, being made of corrugated tube, is flexible and can be easily bent. Furthermore, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used as the constituent material of the first outer component 22.

[0097] (Structure of the second harness 12)

[0098] like Figure 3 As shown, the second wiring harness 12 has a second wire 31 and a second outer casing 32. Multiple second wires 31 are provided, for example. The second outer casing 32 is, for example, cylindrical. The second outer casing 32, for example, surrounds multiple second wires 31 together. Furthermore, one end of the second wire 31 is connected to the third machine M3, and the other end of the second wire 31 is connected to the fourth machine M4. The second wire 31 is a low-voltage wire.

[0099] The second wire 31 has a second core wire 33 and a second insulating covering portion 34 that encloses the outer periphery of the second core wire 33. The second core wire 33 is, for example, made of a flexible conductor that can be easily bent. Furthermore, as an example of such a flexible conductor, it is a stranded wire made of multiple metal wires twisted together. As the material of the second core wire 33, for example, copper-based, aluminum-based, and other metal materials can be used.

[0100] The second insulating cover 34, for example, covers the entire outer periphery of the second core wire 33. The second insulating cover 34 is, for example, made of an insulating material such as synthetic resin. The second insulating cover 34 can be formed, for example, by extrusion molding of the second core wire 33.

[0101] The second outer casing 32 is generally elongated cylindrical. The second wire 31 is inserted into the internal space of the second outer casing 32. The second outer casing 32 protects the second wire 31 from damage by, for example, flying objects or water droplets.

[0102] like Figure 2 As shown, the second outer component 32 is, for example, made of a corrugated tube of synthetic resin. The second outer component 32, as a corrugated tube, is formed with a corrugated shape whose diameter varies repeatedly along its length. That is, the second outer component 32 has recesses 32a and protrusions 32b that are alternately connected along its length. Each of the recesses 32a and protrusions 32b is, for example, formed into a ring that wraps around the circumference of the second outer component 32. The second outer component 32, made of corrugated tube, is flexible and can be easily bent. Furthermore, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used as the constituent material of the second outer component 32.

[0103] like Figure 3 As shown, the first outer component 22 and the second outer component 32 are arranged along the X-axis. The X-axis is perpendicular to the length direction of the first outer component 22 and the second outer component 32. Hereinafter, the direction along the X-axis will sometimes be referred to as the arrangement direction X of the first outer component 22 and the second outer component 32.

[0104] (Structure of the first path restriction component 40)

[0105] like Figure 2 and Figure 3 As shown, the first path limiting member 40 holds the first outer member 22 and the second outer member 32 together. Furthermore, the first path limiting member 40 is more rigid than the first outer member 22 and the second outer member 32. That is, the first path limiting member 40 has a rigidity that makes it less prone to bending in a direction orthogonal to the length direction of the first wire harness 11 and the second wire harness 12 compared to the first outer member 22 and the second outer member 32. Therefore, the first path limiting member 40 restricts the path of the first wire harness 11 and the path of the second wire harness 12. In other words, the first path limiting member 40 assists the first wire harness 11 and the second wire harness 12, preventing them from deviating from their predetermined paths due to their own weight, etc. Therefore, the first outer member 22 and the second outer member 32 are less prone to bending than when the first path limiting member 40 is not installed.

[0106] The first path limiting member 40 is partially provided along the length of the first wire harness 11 and the second wire harness 12. The first path limiting member 40 is installed, for example, in the straight-extending portion of the path of the first wire harness 11 and the second wire harness 12. The first path limiting member 40 is provided singly or in multiples depending on the path of the first wire harness 11 and the second wire harness 12.

[0107] The first path limiting member 40 has a first main body 41 and a first insertion port 42 that cover a portion of the outer periphery of the first outer member 22 and the second outer member 32.

[0108] The first main body portion 41 covers a portion of the outer periphery of the first outer member 22 and the second outer member 32 arranged in the X-direction. The first main body portion 41 extends, for example, in a straight line along the length of the first outer member 22 and the second outer member 32. The cross-sectional shape of the first main body portion 41 is, for example, approximately C-shaped. Furthermore, the cross-sectional shape of the first path limiting member 40 is, for example, the same throughout its entire length. Additionally, the radial thickness of the first main body portion 41 is, for example, the same in the circumferential direction.

[0109] like Figure 3 As shown, the first main body 41 has a covering portion 43, a pair of arms 44a and 44b, a first end portion 45 which is the top end portion of the arm 44a, and a second end portion 46 which is the top end portion of the arm 44b.

[0110] The covering portion 43 covers, for example, the side of the first outer component 22 and the second outer component 32 in the Y-axis direction perpendicular to the arrangement direction X.

[0111] A pair of arms 44a and 44b extend from both ends of the covering portion 43 in the arrangement direction X. The arms 44a and 44b clamp the first outer member 22 and the second outer member 32 together from both sides in the arrangement direction X. Each arm 44a and 44b extends in the Y-axis direction to the side opposite to the covered side of the covering portion 43. That is, the first end 45 of arm 44a and the second end 46 of arm 44b are located in the Y-axis direction opposite to the covered side of the covering portion 43. Arm 44a covers the side of the first outer member 22 in the arrangement direction X. Arm 44b covers the side of the second outer member 32 in the arrangement direction X.

[0112] The first end portion 45 and the second end portion 46 are the two circumferential ends of the first main body portion 41. The first end portion 45 and the second end portion 46 are positioned opposite each other in a circumferentially separated state of the first main body portion 41. The first insertion port 42 is formed through the first end portion 45 and the second end portion 46. That is, the gap between the first end portion 45 and the second end portion 46 constitutes the first insertion port 42.

[0113] like Figure 2 and Figure 3 As shown, the first outer member 22 and the second outer member 32 are in contact with each other while being held by a pair of arms 44a and 44b. Further, in this embodiment, at least in the portion held by the first path limiting member 40, the protrusions and concavities of the outer peripheral surface of the first outer member 22 engage with the protrusions and concavities of the outer peripheral surface of the second outer member 32. That is, the protrusion 22b of the first outer member 22 engages with the concave portion 32a of the second outer member 32, and the protrusion 32b of the second outer member 32 engages with the concave portion 22a of the first outer member 22. Thus, in the holding portion of the first path limiting member 40, the composite wire harness 10 can be miniaturized in the arrangement direction X according to the engagement amount of the first outer member 22 and the second outer member 32. Furthermore, the engagement of the first outer member 22 and the second outer member 32 restricts the relative movement of the first outer member 22 and the second outer member 32 in the longitudinal direction.

[0114] The first insertion port 42 is an opening along the length direction of the first path limiting member 40. Furthermore, the first insertion port 42 opens along the Y-axis. That is, the first insertion port 42 opens in a direction perpendicular to the arrangement direction X. Additionally, the first insertion port 42 extends along the entire length of the first path limiting member 40. The opening width of the first insertion port 42, i.e., the shortest distance between the first end 45 and the second end 46, is less than the length obtained by subtracting the engagement amount of the first outer member 22 and the second outer member 32 from the length obtained by adding the outer diameters of the first outer member 22 and the second outer member 32. The first outer member 22 and the second outer member 32 are inserted into the first insertion port 42 along the Y-axis direction.

[0115] The first path limiting member 40 has a first protrusion 47 protruding from the inner surface of a first end 45 and a second protrusion 48 protruding from the inner surface of a second end 46. The cross-sectional shape of the first protrusion 47 and the second protrusion 48 is, for example, semi-circular. The first protrusion 47 and the second protrusion 48 extend, for example, along the length direction of the first path limiting member 40. In addition, the first protrusion 47 and the second protrusion 48 extend, for example, along the entire length of the first path limiting member 40.

[0116] The first protrusion 47 protrudes toward the first outer member 22. The first protrusion 47 contacts the outer surface of the first outer member 22. Additionally, the second protrusion 48 protrudes toward the second outer member 32. The second protrusion 48 contacts the outer surface of the second outer member 32. Furthermore, the first protrusion 47 and the second protrusion 48, for example, press against the first outer member 22 and the second outer member 32 respectively. The first outer member 22 and the second outer member 32 are elastically clamped by the first protrusion 47, the second protrusion 48, and the first main body portion 41. Thus, the connection between the first path limiting member 40 and the first outer member 22 and the second outer member 32 becomes secure. Therefore, the first path limiting member 40 is prevented from moving along the length direction of the first outer member 22 and the second outer member 32.

[0117] Furthermore, when the first outer member 22 and the second outer member 32 are inserted into the first path limiting member 40, the opening width of the first insertion port 42 may not return to its original width, i.e., the width when the first outer member 22 and the second outer member 32 are not inserted. Specifically, the elastic deformation of each arm 44a and 44b, which would otherwise return to its original shape, is hindered by the first outer member 22 and the second outer member 32, thus sometimes causing the opening width of the first insertion port 42 to become slightly larger than its original width. Additionally, when the first outer member 22 and the second outer member 32 are inserted into the first path limiting member 40, due to the pressure of the first path limiting member 40, the first outer member 22 and the second outer member 32 become flexed, thus sometimes causing the opening width of the first insertion port 42 to return to its original width. That is, when the first outer component 22 and the second outer component 32 are inserted into the interior of the first path limiting component 40, the opening width of the first insertion port 42 becomes based on the rigidity, flexibility, etc. of the first outer component 22, the second outer component 32, and the first path limiting component 40.

[0118] like Figure 3 As shown, in the first path limiting member 40, when viewed from the length direction of the first path limiting member 40, the circumferential tip 45a of the first end 45 and the circumferential tip 46a of the second end 46 are each curved. In other words, the cross-sectional shape of the tip 45a of the first end 45 and the tip 46a of the second end 46 is formed into a curved shape. Furthermore, the first insertion port 42 is formed by the tip 45a of the first end 45 and the tip 46a of the second end 46. In addition, the first protrusion 47 protrudes from the inner surface of the tip 45a of the first end 45. The second protrusion 48 protrudes from the inner surface of the tip 46a of the second end 46.

[0119] Furthermore, synthetic resins such as polypropylene, polyamide, and polyoxymethylene can be used as materials for the first path limiting member 40. The first path limiting member 40 can be formed, for example, by known methods such as extrusion molding and injection molding. Moreover, as described above, the first path limiting member 40 is harder than the first outer component 22 and the second outer component 32, but the constituent material of the first path limiting member 40 does not necessarily have to be a material harder than the constituent materials of the first outer component 22 and the second outer component 32. That is, the constituent material of the first path limiting member 40 can be either a material harder or softer than the constituent materials of the first outer component 22 and the second outer component 32. Alternatively, the constituent material of the first path limiting member 40 can also be the same material as the constituent materials of the first outer component 22 and the second outer component 32.

[0120] The first path limiting member 40 in this embodiment is, for example, made of a colored synthetic resin material. Here, the color of the synthetic resin material constituting the first path limiting member 40 is set to a color that allows the operator to identify that the wires included in the composite wire harness 10 are high-voltage wires.

[0121] Furthermore, the composite wiring harness 10 is fixed to the vehicle body using a fixing member (not shown). Multiple fixing points are provided along the path of the composite wiring harness 10, where the fixing member secures it to the vehicle body. These fixing points are located in sections where the first path limiting member 40 is provided, or in sections where the first path limiting member 40 is not provided.

[0122] The function of this embodiment will be explained.

[0123] According to the composite wire harness 10 of this embodiment, in the portion where the first path limiting member 40 is installed, the rigidity of the first path limiting member 40 is used to suppress the deflection of the first wire harness 11 and the second wire harness 12 due to their own weight, etc. In other words, the first path limiting member 40 restricts the paths of both the first wire harness 11 and the second wire harness 12.

[0124] Furthermore, existing structures include those where the first outer component 22 is a rigid tubular component such as a metal tube, which serves to both protect the first wire 21 and restrict its path. In such structures, the tubular component is elongated, and bending processes using a bending machine or similar equipment are required at the bends in the path of the first wire 21. This bending process is a complex operation. However, in the composite wire harness 10 of this embodiment, the first path-restricting component 40 is installed on the straight sections of the composite wire harness 10's path, thus eliminating the need for bending processes using a bending machine or similar equipment as in the past.

[0125] The effects of the first embodiment will be explained.

[0126] (1) The first insertion port 42 of the first path limiting member 40 is an opening extending along the length of the first path limiting member 40 and extending throughout the entire length of the first path limiting member 40. According to this structure, after end processing such as installing connectors at the ends of the first wire 21 and the second wire 31 along their respective lengths, the first path limiting member 40 can be installed on the first outer member 22 and the second outer member 32 from the first insertion port 42. In this way, the first path limiting member 40 can be installed on the first outer member 22 and the second outer member 32, thereby improving the assembly workability of the composite wire harness 10.

[0127] In addition, the first path limiting member 40 holds the first outer component 22 and the second outer component 32 together, limiting the paths of the first wire harness 11 and the second wire harness 12. That is, the paths of multiple wire harnesses can be limited by one first path limiting member 40, thus helping to reduce the number of components in the composite wire harness 10.

[0128] Furthermore, the first path limiting member 40 is more rigid than the first outer member 22 and the second outer member 32. That is, the first path limiting member 40 has a rigidity that makes it less prone to bending than the first outer member 22 and the second outer member 32. According to this structure, the paths of the first wire harness 11 and the second wire harness 12 can be more firmly restricted by the rigid first path limiting member 40.

[0129] (2) The first path limiting member 40 has a first protrusion 47 and a second protrusion 48. The first protrusion 47 protrudes from the inner surface of the first end 45 and contacts the outer surface of the first outer member 22. The second protrusion 48 protrudes from the inner surface of the second end 46 and contacts the outer surface of the second outer member 32. According to this structure, the first outer member 22 and the second outer member 32 can be prevented from falling off the first path limiting member 40 through the first insertion port 42 by means of the first protrusion 47 and the second protrusion 48. As a result, accidental falling off of the first path limiting member 40 can be prevented, thereby improving the assembly workability of the composite wire harness 10.

[0130] (3) The first path limiting member 40 is made of a colored synthetic resin material. According to this structure, the first path limiting member 40 can be set to a desired color even without surface coating. Therefore, by setting the color of the first path limiting member 40 to a color that allows the operator to identify that the composite wiring harness 10 includes the first wire 21, which is a high-voltage wire, it is possible to draw the operator's attention and prevent them from accidentally cutting the first wire 21.

[0131] (4) When viewed from the length direction of the first path limiting member 40, the tip 45a of the first end 45 and the tip 46a of the second end 46 are each bent. Therefore, the first outer member 22 and the second outer member 32 can be smoothly inserted into the interior of the first path limiting member 40 through the first insertion port 42 formed by the tips 45a and 46a. In addition, the first outer member 22 and the second outer member 32 are less likely to be damaged when inserted into the interior of the first path limiting member 40 through the first insertion port 42.

[0132] (5) The cross-sectional shape of the first path limiting member 40 is the same throughout its entire length. With this structure, the first path limiting member 40 can be easily manufactured using an extrusion molding machine that extrudes the raw material of the first path limiting member 40 in the longitudinal direction. Furthermore, multiple types of first path limiting members 40 with different dimensions in the longitudinal direction can be manufactured using a single extrusion molding machine.

[0133] (6) The first protrusion 47 and the second protrusion 48 extend along the entire length of the first path limiting member 40. This structure improves the bending stiffness of the first path limiting member 40. Furthermore, the first protrusion 47 and the second protrusion 48, along the entire length of the first path limiting member 40, contact the outer surfaces of the first outer member 22 and the second outer member 32, respectively. Therefore, extending along the entire length of the first path limiting member 40 prevents the first path limiting member 40 from disengaging from the first outer member 22 and the second outer member 32 through the first insertion port 42.

[0134] <Second Implementation Method>

[0135] Next, a second embodiment of the composite wire harness will be described. Furthermore, in this embodiment, the differences from the first embodiment will be mainly described, and the same reference numerals will be used to label structures identical to those in the first embodiment; sometimes, part or all of the description may be omitted.

[0136] like Figure 4 and Figure 5 As shown, the first path limiting member 40 has a partition 49 protruding from the first main body portion 41 toward the first insertion port 42. The partition 49 extends, for example, along the entire length of the first path limiting member 40. The partition 49 is located between the first outer member 22 and the second outer member 32. That is, the partition 49 separates the first outer member 22 and the second outer member 32. The first outer member 22 is disposed between the partition 49 and the first end portion 45. The second outer member 32 is disposed between the partition 49 and the second end portion 46.

[0137] The partition 49 has a first protrusion 49a protruding from the top of the partition 49 toward the first outer member 22 and a second protrusion 49b protruding from the top of the partition 49 toward the second outer member 32. The first protrusion 49a contacts the outer peripheral surface of the first outer member 22. The second protrusion 49b contacts the outer peripheral surface of the second outer member 32.

[0138] Furthermore, the shortest distance between the top end of the partition 49 and the first end 45 is less than the outer diameter of the first outer member 22. Additionally, the shortest distance between the top end of the partition 49 and the second end 46 is less than the outer diameter of the second outer member 32.

[0139] The effects of the second embodiment will be explained.

[0140] (7) In the first path limiting member 40, the division between the portion where the first outer member 22 is disposed and the portion where the second outer member 32 is disposed is made by the partition 49. Therefore, the workability when assembling the first outer member 22 and the second outer member 32 in the first path limiting member 40 can be improved.

[0141] (8) The partition 49 has a first protrusion 49a protruding from the top of the partition 49 toward the first outer member 22. Therefore, the first protrusion 49a can be used to prevent the first outer member 22 from falling off the first path limiting member 40. Additionally, the partition 49 has a second protrusion 49b protruding from the top of the partition 49 toward the second outer member 32. Therefore, the second protrusion 49b can be used to prevent the second outer member 32 from falling off the first path limiting member 40.

[0142] <Third Implementation Method>

[0143] Next, a third embodiment of the composite wire harness will be described. Furthermore, in this embodiment, the differences from the first embodiment will be mainly described, and the same reference numerals will be used to label structures identical to those in the first embodiment; sometimes, part or all of the description may be omitted.

[0144] like Figure 6 and Figure 7 As shown, the composite wire harness 10A of this embodiment includes a second path limiting member 50 mounted on the outer periphery of the first outer member 22. Additionally, the composite wire harness 10A includes a first path limiting member 40 that holds the first wire harness 11 and the second wire harness 12 together. The first path limiting member 40 is disposed outside the second path limiting member 50. That is, the second path limiting member 50 is disposed between the outer peripheral surface of the first outer member 22 and the first path limiting member 40.

[0145] (Structure of the second path restriction component 50)

[0146] The second path limiting member 50 covers a portion of the circumferential portion of the outer periphery of the first outer member 22. Furthermore, the second path limiting member 50 is more rigid than the first outer member 22. That is, the second path limiting member 50 has a rigidity that makes it less prone to bending in a direction orthogonal to the length direction of the first wire harness 11 compared to the first outer member 22. Therefore, the second path limiting member 50 assists the first outer member 22 in preventing it from deviating from its predetermined path due to its own weight or other factors. In other words, the first outer member 22 is less prone to bending than when the second path limiting member 50 is not installed.

[0147] The second path limiting member 50 is partially provided along the length of the first outer component 22. The second path limiting member 50 is installed, for example, in a straight section extending along the path of the first wiring harness 11. The second path limiting member 50 may be provided singly or in multiples depending on the path of the first wiring harness 11.

[0148] like Figure 7 As shown, the second path limiting member 50 has a second main body 51 that covers a circumferential portion of the outer periphery of the first outer member 22 and a second insertion port 52.

[0149] The second main body portion 51 covers a portion of the circumferential direction of the outer peripheral surface of the first outer member 22. For example, the second main body portion 51 covers more than half of the outer periphery of the first outer member 22. Furthermore, the second main body portion 51 extends along the length direction of the first outer member 22. The cross-sectional shape of the second main body portion 51 is, for example, arc-shaped. Furthermore, the radial thickness of the second main body portion 51 is, for example, the same in the circumferential direction. Furthermore, the cross-sectional shape of the second path limiting member 50 is, for example, the same throughout its entire length. Furthermore, the central axis C in the cross-section of the second main body portion 51 is, for example, a straight line. That is, the second main body portion 51 is formed in a shape that extends linearly in one direction.

[0150] The second main body 51 has a third end 53 and a fourth end 54, which are the two circumferential ends of the second path limiting member 50. The third end 53 and the fourth end 54 are positioned opposite each other in a circumferentially separated state from the second path limiting member 50. The second insertion port 52 is formed through the third end 53 and the fourth end 54 of the second main body 51. That is, the gap between the third end 53 and the fourth end 54 constitutes the second insertion port 52.

[0151] The second insertion port 52 is an opening along the length of the second path limiting member 50. Furthermore, the second insertion port 52 extends along the entire length of the second path limiting member 50. The opening width of the second insertion port 52, i.e., the shortest distance between the third end 53 and the fourth end 54, is less than the outer diameter of the first outer member 22. The first outer member 22 is inserted into the second insertion port 52 in a direction orthogonal to the length of the second path limiting member 50.

[0152] In the cross-section of the second path limiting member 50, the tangent passing through the third end 53 of the central axis C of the second main body 51 is designated as tangent T1, and the tangent passing through the fourth end 54 of the central axis C is designated as tangent T2. The opening angle θ of the second insertion port 52 in the circumferential direction of the second path limiting member 50 is, for example, in the range of 60° to 120°. Furthermore, the opening angle θ of the second insertion port 52 is the angle centered on the central axis C of the second main body 51, that is, the angle formed by tangent T1 and tangent T2.

[0153] The second path limiting member 50 has a third protrusion 55 protruding from the inner surfaces of the third end 53 and the fourth end 54, respectively. The cross-sectional shape of each third protrusion 55 is, for example, semi-circular. Each third protrusion 55 extends, for example, along the length direction of the second path limiting member 50. In addition, each third protrusion 55 extends, for example, along the entire length of the second path limiting member 50.

[0154] Each third protrusion 55 protrudes toward the first outer member 22. Each third protrusion 55 contacts the outer surface of the first outer member 22. Furthermore, each third protrusion 55 presses against the first outer member 22, for example. The first outer member 22 is elastically held between each third protrusion 55 and the second main body portion 51. Thus, the connection between the second path limiting member 50 and the first outer member 22 becomes secure. Therefore, the second path limiting member 50, mounted on the outer periphery of the first outer member 22, is prevented from moving along the length direction of the first outer member 22.

[0155] Furthermore, when the first outer component 22 is inserted into the second path-limiting component 50, the opening width of the second insertion port 52 may not return to its original width, i.e., the width when the first outer component 22 is not inserted. Specifically, the elastic deformation of the second path-limiting component 50 that would otherwise return to its original shape is hindered by the first outer component 22, thus the opening width of the second insertion port 52 may sometimes become slightly larger than its original width. Additionally, when the first outer component 22 is inserted into the second path-limiting component 50, due to the pressure of the second path-limiting component 50, the first outer component 22 becomes flexed, thus the opening width of the second insertion port 52 may sometimes return to its original width. In other words, the opening width when the first outer component 22 is inserted into the second path-limiting component 50 becomes based on the rigidity, flexibility, etc., of the first outer component 22 and the second path-limiting component 50.

[0156] In the second path limiting member 50, when viewed from the length direction of the second path limiting member 50, the circumferential tip 53a of the third end 53 and the circumferential tip 54a of the fourth end 54 are each curved. In other words, the cross-sectional shape of the tip 53a of the third end 53 and the tip 54a of the fourth end 54 is formed into a curved shape. Furthermore, the second insertion port 52 is formed by the tip 53a of the third end 53 and the tip 54a of the fourth end 54. In addition, the third protrusion 55 protrudes from the inner surface of the tip 53a of the third end 53 and the tip 54a of the fourth end 54.

[0157] Furthermore, synthetic resins such as polypropylene, polyamide, and polyoxymethylene can be used as materials for the second path limiting member 50. The second path limiting member 50 can be formed, for example, by known methods such as extrusion molding and injection molding. Moreover, as described above, the second path limiting member 50 is harder than the first outer component 22, but the constituent material of the second path limiting member 50 does not necessarily have to be a material harder than the constituent material of the first outer component 22. That is, the constituent material of the second path limiting member 50 can be either a material harder or softer than the constituent material of the first outer component 22. Alternatively, the constituent material of the second path limiting member 50 can also be the same material as the constituent material of the first outer component 22.

[0158] The second path limiting member 50 in this embodiment is, for example, made of a colored synthetic resin material. Here, the color of the synthetic resin material constituting the second path limiting member 50 is set such that an operator can identify that the first wire 21 included in the first wiring harness 11 is a high-voltage wire. Furthermore, in this embodiment, the second path limiting member 50 is set to the same color as the first path limiting member 40.

[0159] The second path limiting member 50 is disposed inside the first main body portion 41 of the first path limiting member 40. Furthermore, the second path limiting member 50 is, for example, longer than the first path limiting member 40 in the length direction of the first wire harness 11. The arm portion 44a of the first main body portion 41 contacts the second main body portion 51 of the second path limiting member 50. The arm portion 44a presses against the second main body portion 51, for example, in the arrangement direction X. Additionally, the first insertion port 42 of the first path limiting member 40 and the second insertion port 52 of the second path limiting member 50 open, for example, in the same direction along the Y-axis.

[0160] The first end portion 45 of the first main body portion 41 extends longer than the third end portion 53 of the second main body portion 51 in the circumferential direction of the first outer fitting member 22. Thus, the first end portion 45 faces the outer circumferential surface of the first outer fitting member 22. Furthermore, in Figure 7 In the structure shown, in the first path limiting member 40, the first protrusion 47 of the first end 45 does not contact the outer peripheral surface of the first outer member 22, but it is not limited to this. The first protrusion 47 may also be configured to contact the outer peripheral surface of the first outer member 22.

[0161] The effects of the third embodiment will be explained.

[0162] (9) The paths of the first wire harness 11 and the second wire harness 12 can be more appropriately restricted by the first path restriction member 40 and the second path restriction member 50.

[0163] Furthermore, a second path-limiting member 50 is installed on the inner side of the first path-limiting member 40 and mounted on the first outer member 22, thus providing more adequate protection for the first outer member 22 against damage from flying objects. As a result, this contributes to improving the durability of the composite wire harness 10A.

[0164] Furthermore, since the first outer component 22 is double-covered by the first path limiting component 40 and the second path limiting component 50, heat transfer from the outside to the first outer component 22 can be more appropriately suppressed.

[0165] Furthermore, the second insertion port 52 of the second path limiting member 50 is an opening extending along the length of the second path limiting member 50 and extending throughout the entire length of the second path limiting member 50. Therefore, after end processing such as installing a connector at the end of the first wire 21 along its length, the second path limiting member 50 can be installed onto the first outer component 22 through the second insertion port 52. This allows the second path limiting member 50 to be installed after the first outer component 22, thus improving the assembly workability of the composite wire harness 10A.

[0166] Furthermore, the first path limiting member 40 also holds the first outer component 22 and the second outer component 32. Therefore, the first outer component 22 and the second outer component 32 can be connected to each other using the first path limiting member 40.

[0167] Furthermore, the second path limiting member 50 is more rigid than the first outer member 22. That is, the second path limiting member 50 has a rigidity that makes it less prone to bending than the first outer member 22. According to this structure, the path of the first wire harness 11 can be more firmly restricted by the rigid second path limiting member 50.

[0168] (10) The second path limiting member 50 is longer than the first path limiting member 40 in the length direction of the first wire harness 11. According to this structure, for example, when the first wire harness 11 requires path limiting in a section longer than the second wire harness 12, instead of lengthening the first path limiting member 40, the second path limiting member 50 mounted on the first outer component 22 is lengthened to correspond, thereby limiting only the portions requiring path limiting. That is, the first path limiting member 40 does not need to be extended to the sections of the second wire harness 12 that do not require path limiting, which contributes to the miniaturization of the first path limiting member 40 and, consequently, to the weight reduction of the composite wire harness 10A.

[0169] (11) The second path limiting member 50 has a third protrusion 55, which protrudes from the inner surfaces of the third end 53 and the fourth end 54 and contacts the outer surface of the first outer member 22. According to this structure, the third protrusion 55 can be used to prevent the first outer member 22 from falling off the second path limiting member 50 through the second insertion port 52. Therefore, accidental detachment of the second path limiting member 50 can be prevented, thus further improving the assembly workability of the composite wire harness 10A.

[0170] (12) The second path limiting member 50 is made of a colored synthetic resin material. According to this structure, the second path limiting member 50 can be set to a desired color even without surface coating. Therefore, by setting the color of the second path limiting member 50 to a color that allows the operator to identify that the first wiring harness 11 includes the first wire 21, which is a high-voltage wire, it is possible to draw the operator's attention and prevent them from mistakenly cutting the first wiring harness 11.

[0171] (13) The second path limiting member 50 is set to the same color as the first path limiting member 40. This allows the operator to more properly identify that the composite wire harness 10A includes high-voltage wires.

[0172] (14) When viewed from the length direction of the second path limiting member 50, the tip 53a of the third end 53 and the tip 54a of the fourth end 54 are each bent. Therefore, the first outer member 22 can be smoothly inserted into the interior of the second path limiting member 50 through the second insertion port 52 formed by the tips 53a and 54a. In addition, the first outer member 22 is less likely to be damaged when it is inserted into the interior of the second path limiting member 50 through the second insertion port 52.

[0173] (15) The cross-sectional shape of the second path limiting member 50 is the same throughout its entire length. With this structure, the second path limiting member 50 can be easily manufactured using an extrusion molding machine that extrudes the raw material of the second path limiting member 50 in the longitudinal direction. Furthermore, multiple types of second path limiting members 50 with different dimensions in the longitudinal direction can be manufactured using a single extrusion molding machine.

[0174] (16) The third protrusion 55 extends along the entire length of the second path limiting member 50. This structure improves the bending stiffness of the second path limiting member 50. Furthermore, the third protrusion 55 contacts the outer surface of the first outer member 22 along the entire length of the second path limiting member 50. Therefore, extending along the entire length of the second path limiting member 50 prevents the second path limiting member 50 from disengaging from the first outer member 22 through the second insertion port 52.

[0175] <Fourth Implementation>

[0176] Next, a fourth embodiment of the composite wire harness will be described. Furthermore, in this embodiment, the differences from the first embodiment will be mainly described, and the same reference numerals will be used to label structures identical to those in the first embodiment; sometimes, part or all of the description will be omitted.

[0177] like Figure 8 and Figure 9 As shown, the composite wire harness 10B of this embodiment includes a third path limiting member 60 installed on the outer periphery of the first path limiting member 40. The third path limiting member 60 limits the paths of the first wire harness 11 and the second wire harness 12.

[0178] (Structure of the third path restriction member 60)

[0179] like Figure 8 and Figure 9 As shown, the third path limiting member 60 includes a third body portion 61 that covers a portion of the outer periphery of the first path limiting member 40 and a third insertion port 62. Furthermore, the third path limiting member 60 is made of, for example, a metallic material. The third path limiting member 60 can be formed, for example, by methods such as stamping or casting of a metal sheet.

[0180] The third main body portion 61 is shaped to be one size larger than the first main body portion 41 of the first path limiting member 40. The third main body portion 61 extends, for example, in a straight line along the length direction of the first outer member 22 and the second outer member 32. That is, the third main body portion 61 extends along the length direction of the first main body portion 41. The cross-sectional shape of the third main body portion 61 is, for example, approximately C-shaped. Furthermore, the cross-sectional shape of the third path limiting member 60 is, for example, the same throughout its entire length. Additionally, the radial thickness of the third main body portion 61 is, for example, the same in the circumferential direction. Furthermore, the third main body portion 61 is, for example, shorter than the first main body portion 41 in the length direction of the first path limiting member 40.

[0181] like Figure 9 As shown, the third main body 61 has a covering portion 63, a pair of arms 64a and 64b, a fifth end portion 65 which is the top end portion of the arm 64a, and a sixth end portion 66 which is the top end portion of the arm 64b.

[0182] The covering portion 63, for example, covers the outer side of the covering portion 43 in the Y-axis direction, which is perpendicular to the X-axis arrangement direction. The covering portion 63, for example, contacts the covering portion 43.

[0183] A pair of arms 64a and 64b extend from both ends of the covering portion 63 in the arrangement direction X. The pair of arms 64a and 64b sandwich the first path limiting member 40 from both sides in the arrangement direction X. Arm 64a contacts arm 44a of the first path limiting member 40. In addition, arm 64b contacts arm 44b of the first path limiting member 40.

[0184] The fifth end portion 65, which is the tip of the arm portion 64a, extends longer than the first end portion 45 of the first main body portion 41 in the circumferential direction of the first outer member 22. Therefore, the fifth end portion 65 faces the outer circumferential surface of the first outer member 22. Similarly, the sixth end portion 66, which is the tip of the arm portion 64b, extends longer than the second end portion 46 of the first main body portion 41 in the circumferential direction of the second outer member 32. Therefore, the sixth end portion 66 faces the outer circumferential surface of the second outer member 32.

[0185] The fifth end 65 and the sixth end 66 are the two circumferential ends of the third main body 61. The fifth end 65 and the sixth end 66 are located on the side opposite to the covered side of the covering portion 63 in the Y-axis direction. The fifth end 65 and the sixth end 66 are positioned opposite each other in a circumferentially separated state in the third main body 61. The third insertion port 62 is formed through the fifth end 65 and the sixth end 66. That is, the gap between the fifth end 65 and the sixth end 66 constitutes the third insertion port 62.

[0186] The third insertion port 62 is an opening along the length direction of the third path limiting member 60. Furthermore, the third insertion port 62 opens along the Y-axis. That is, the third insertion port 62 opens in a direction perpendicular to the arrangement direction X. Additionally, the third insertion port 62 extends along the entire length of the third path limiting member 60. The opening width of the third insertion port 62, i.e., the shortest distance between the fifth end 65 and the sixth end 66, is less than the size of the first path limiting member 40 in the arrangement direction X. The first path limiting member 40 is inserted into the third insertion port 62 along the Y-axis direction.

[0187] The third path limiting member 60 has a fourth protrusion 67 projecting from the inner surfaces of the fifth end 65 and the sixth end 66, respectively. The cross-sectional shape of each fourth protrusion 67 is, for example, semi-circular. Each fourth protrusion 67 extends, for example, along the length of the third path limiting member 60. Furthermore, each fourth protrusion 67 extends, for example, along the entire length of the third path limiting member 60.

[0188] The fourth protrusion 67, located at the fifth end 65, contacts, for example, the first end 45 of the first main body 41. Additionally, the fourth protrusion 67, located at the sixth end 66, contacts, for example, the second end 46 of the first main body 41. Furthermore, in... Figure 9 In the structure shown, the fourth protrusion 67 does not contact the outer peripheral surface of the first outer component 22 and the outer peripheral surface of the second outer component 32. However, it is not limited to this. The fourth protrusion 67 may also be configured to contact the outer peripheral surface of the first outer component 22 and the outer peripheral surface of the second outer component 32 respectively.

[0189] like Figure 9 As shown, in the third path limiting member 60, when viewed from the length direction of the third path limiting member 60, the circumferential tip 65a of the fifth end 65 and the circumferential tip 66a of the sixth end 66 are each curved. In other words, the cross-sectional shape of the tip 65a of the fifth end 65 and the tip 66a of the sixth end 66 is formed into a curved shape. Furthermore, the third insertion port 62 is formed by the tip 65a of the fifth end 65 and the tip 66a of the sixth end 66. In addition, the fourth protrusion 67 protrudes from the inner surface of the tip 65a of the fifth end 65 and the tip 66a of the sixth end 66.

[0190] The first path limiting member 40 is disposed between the first outer member 22 and the second outer member 32 and the third path limiting member 60. The first insertion port 42 of the first path limiting member 40 and the third insertion port 62 of the third path limiting member 60 are, for example, open in the same direction along the Y-axis.

[0191] The third path limiting member 60 is more rigid than the first outer member 22 and the second outer member 32. That is, the third path limiting member 60 has a higher degree of rigidity than the first outer member 22 and the second outer member 32 in a direction orthogonal to the length direction of the first wire harness 11 and the second wire harness 12. Therefore, the third path limiting member 60 restricts the paths of the first wire harness 11 and the second wire harness 12. In other words, the first outer member 22 and the second outer member 32 are less prone to bending than when the third path limiting member 60 is not installed.

[0192] The effects of the fourth embodiment will be explained.

[0193] (17) The paths of the first harness 11 and the second harness 12 can be more appropriately restricted by the first path restriction member 40 and the third path restriction member 60.

[0194] Furthermore, because the third path limiting member 60 is located outside the first path limiting member 40, the first outer member 22 and the second outer member 32 can be more properly protected from damage by flying objects or the like. As a result, the durability of the composite wire harness 10B can be improved.

[0195] Furthermore, since the first outer component 22 and the second outer component 32 are double-covered by the first path limiting component 40 and the third path limiting component 60, heat transfer from the outside to the first outer component 22 and the second outer component 32 can be more appropriately suppressed.

[0196] Furthermore, the third insertion port 62 of the third path limiting member 60 is an opening extending along the length of the third path limiting member 60 and extending along the entire length of the third path limiting member 60. Therefore, the third path limiting member 60 can be installed through the third insertion port 62, thus improving the assembly workability of the composite wire harness 10B.

[0197] Furthermore, the third path limiting member 60 is more rigid than the first outer member 22 and the second outer member 32. That is, the third path limiting member 60 has a rigidity that makes it less prone to bending than the first outer member 22 and the second outer member 32. According to this structure, the paths of the first wire harness 11 and the second wire harness 12 can be more firmly restricted by the rigid third path limiting member 60.

[0198] (18) The third path limiting member 60 is shorter than the first path limiting member 40 in the length direction. According to this structure, the third path limiting member 60 can be provided only at the locations in the composite wire harness 10B where it is needed. Therefore, the third path limiting member 60 does not need to extend to locations where it is not required, which helps to miniaturize the third path limiting member 60 and, consequently, to reduce the weight of the composite wire harness 10B.

[0199] (19) The third path limiting member 60 is made of metal. According to this structure, the third path limiting member 60, which is made of metal, can effectively isolate heat transferred from the outside to the first outer member 22 and the second outer member 32.

[0200] (20) The first path limiting member 40, disposed between the first outer component 22 and the second outer component 32 and the third path limiting member 60, is made of synthetic resin. Therefore, the use of a synthetic resin first path limiting member 40 can suppress contact between the metal third path limiting member 60 and the first outer component 22 and the second outer component 32. As a result, wear of the first outer component 22 and the second outer component 32 due to contact with the metal third path limiting member 60 can be suppressed.

[0201] <Fifth Implementation>

[0202] Next, a fifth embodiment of the composite wire harness will be described. Furthermore, in this embodiment, the differences from the second embodiment will be mainly described, and the same reference numerals will be used to label structures identical to those in the second embodiment; sometimes, part or all of the description may be omitted.

[0203] like Figure 10 and Figure 11 As shown, the composite wire harness 10C of this embodiment includes a first wire harness 11A, a second wire harness 12A, and a first path limiting member 40 mounted on the first wire harness 11A and the second wire harness 12A. The first wire harness 11A and the second wire harness 12A are arranged side by side. The first wire harness 11A and the second wire harness 12A are, for example, different in size. The first wire harness 11A is, for example, larger than the second wire harness 12A.

[0204] (Structure of harness 11A and harness 12A)

[0205] like Figure 11 As shown, the first wire harness 11A has two first wires 21 and a cylindrical first outer casing 22 that surrounds the two first wires 21 together. The second wire harness 12A has three second wires 31 and a cylindrical second outer casing 32 that surrounds the three second wires 31 together.

[0206] The two first wires 21 are wires constituting a DC circuit. For example, the two first wires 21 are a high-voltage wire on the positive side and a high-voltage wire on the negative side. The three second wires 31 are wires constituting a three-phase circuit. For example, the three second wires 31 are three-phase cables. Each first wire 21 is, for example, larger in shape than each second wire 31. Here, in this embodiment, both the first wire 21 and each second wire 31 are formed in a cylindrical shape. For example, the outer diameter of each first wire 21 is larger than the outer diameter of each second wire 31. The first outer component 22 is, for example, larger in shape than the second outer component 32. Here, in this embodiment, both the first outer component 22 and the second outer component 32 are formed in a cylindrical shape. For example, the outer diameter of the first outer component 22 is larger than the outer diameter of the second outer component 32.

[0207] (Structure of the first path restriction component 40)

[0208] The first path limiting member 40 has a first main body 41 and a first insertion port 42. The first main body 41 has a covering portion 43, a pair of arms 44a and 44b, a first end portion 45, and a second end portion 46. The covering portion 43 is, for example, formed as a flat plate parallel to the length direction and arrangement direction X of the first path limiting member 40. When viewed from the length direction of the first path limiting member 40, the arms 44a and 44b are formed as plates that are curved into arc shapes that convex to opposite sides. When viewed from the length direction of the first path limiting member 40, the arm 44a is, for example, formed into an arc shape curved along the outer peripheral surface of the first outer member 22. When viewed from the length direction of the first path limiting member 40, the arm 44b is, for example, formed into an arc shape curved along the outer peripheral surface of the second outer member 32.

[0209] The first path limiting member 40 has a partition 70 protruding from the covering portion 43 toward the first insertion port 42. For example... Figure 10 As shown, the partition 70 extends, for example, along the length direction of the first path limiting member 40. The partition 70 extends, for example, along the entire length of the first path limiting member 40.

[0210] like Figure 11As shown, the partition 70 is located between the first outer member 22 and the second outer member 32. That is, the partition 70 separates the first outer member 22 and the second outer member 32. The first outer member 22 is disposed between the partition 70 and the arm portion 44a. The second outer member 32 is disposed between the partition 70 and the arm portion 44b. In other words, in the first path limiting member 40, a first storage portion 81 for storing the first outer member 22 is formed by the space surrounded by the partition 70, the arm portion 44a, and a portion of the covering portion 43. Furthermore, in the first path limiting member 40, a second storage portion 82 for storing the second outer member 32 is formed by the space surrounded by the partition 70, the arm portion 44b, and a portion of the covering portion 43. And the partition 70 separates the first storage portion 81 and the second storage portion 82. In other words, the first path limiting member 40 of this embodiment has a first storage portion 81 and a second storage portion 82 and a partition portion 70 that separates the first storage portion 81 and the second storage portion 82.

[0211] (Overview of the structure of the first storage section 81 and the second storage section 82)

[0212] like Figure 12 As shown, the first storage portion 81 and the second storage portion 82 each extend along the length direction of the first path limiting member 40. The first storage portion 81 and the second storage portion 82 each extend along the entire length of the first path limiting member 40.

[0213] The first storage portion 81 has a first storage opening 83 that opens in a direction orthogonal to the length direction of the first path limiting member 40. The second storage portion 82 has a second storage opening 84 that opens in a direction orthogonal to the length direction of the first path limiting member 40. The first storage opening 83 and the second storage opening 84 each extend along the entire length of the first path limiting member 40. The first storage opening 83 and the second storage opening 84 constitute a first insertion port 42.

[0214] like Figure 11 As shown, the cross-sectional shape of the inner surface of the first storage portion 81 is, for example, formed as an arc. The cross-sectional shape of the inner surface of the first storage portion 81 is formed as a C-shape with a first storage opening 83 in a portion of the circumference of the first storage portion 81. The cross-sectional shape of the inner surface of the second storage portion 82 is, for example, formed as an arc. The cross-sectional shape of the inner surface of the second storage portion 82 is formed as a C-shape with a second storage opening 84 in a portion of the circumference of the second storage portion 82.

[0215] like Figure 12 As shown, the first storage section 81 and the second storage section 82 have, for example, the same shape as each other. For example, the first storage section 81 and the second storage section 82 do not internally store the first wire harness 11A and the second wire harness 12A (see reference). Figure 11 In this state, they are formed to have the same shape as each other. Furthermore, the cross-sectional shape of the first storage portion 81 and the second storage portion 82 is, for example, the same along the entire length of the first path limiting member 40. Additionally, the central axis C1 in the cross-section of the first storage portion 81 is, for example, a straight line, and the central axis C2 in the cross-section of the second storage portion 82 is, for example, a straight line. That is, the first storage portion 81 and the second storage portion 82 are formed in a shape that extends in a straight line in one direction.

[0216] (Structure of partition 70)

[0217] like Figure 11 As shown, the partition 70 has a base end portion connected to the covering portion 43, a top end portion disposed on the opposite side of the base end portion in the Y-axis direction, and an intermediate portion 73 disposed between the base end portion and the top end portion.

[0218] The base end of the partition 70 has, for example, a first hem portion 71 and a second hem portion 72 extending in a direction different from the first hem portion 71. One end of the first hem portion 71 is connected to the covering portion 43, and the other end is connected to the middle portion 73 of the partition 70. One end of the second hem portion 72 is connected to the covering portion 43, and the other end is connected to the middle portion 73 of the partition 70. The first hem portion 71 and the second hem portion 72 extend from the middle portion 73 of the partition 70 toward the covering portion 43 and in opposite directions in the arrangement direction X. That is, the base end of the partition 70 is formed in such a way that it branches from the middle portion 73 into two first hem portions 71 and second hem portions 72.

[0219] The first hem portion 71 constitutes the first storage portion 81. Viewed along the length of the first path limiting member 40, the first hem portion 71 is, for example, formed into an arc shape curved along the outer peripheral surface of the first outer member 22. The cross-sectional shape of the first hem portion 71 is, for example, formed into an arc shape extending along the same circumference as the arm portion 44a. The second hem portion 72 constitutes the second storage portion 82. Viewed along the length of the first path limiting member 40, the second hem portion 72 is, for example, formed into an arc shape curved along the outer peripheral surface of the second outer member 32. The cross-sectional shape of the second hem portion 72 is, for example, formed into an arc shape extending along the same circumference as the arm portion 44b. Viewed along the length of the first path limiting member 40, the first hem portion 71 and the second hem portion 72 are, for example, formed into curved shapes that convex towards each other in opposite directions.

[0220] One end of the first hem portion 71 and one end of the second hem portion 72 are connected, for example, by a covering portion 43 extending in the arrangement direction X. The first path limiting member 40 includes, for example, a space S1 defined by the first hem portion 71, the second hem portion 72, and the covering portion 43. When viewed from the length direction of the first path limiting member 40, the space S1 is, for example, formed as a trapezoid or a triangle. The space S1 extends, for example, along the entire length of the first path limiting member 40.

[0221] The middle portion 73 is formed, for example, by merging the first hem portion 71 and the second hem portion 72 into one. The middle portion 73 is shared by both the first storage portion 81 and the second storage portion 82. That is, the middle portion 73 constitutes both the first storage portion 81 and the second storage portion 82. The middle portion 73 has a first inner surface 73A that forms the inner surface of the first storage portion 81 and a second inner surface 73B that forms the inner surface of the second storage portion 82. The first inner surface 73A and the second inner surface 73B are the two end faces of the middle portion 73 in the arrangement direction X.

[0222] The cross-sectional shape of the first inner surface 73A is, for example, formed as an arc shape curved along the outer peripheral surface of the first outer member 22. The cross-sectional shape of the first inner surface 73A is, for example, formed as an arc shape extending on the same circumference as the inner surface of the arm portion 44a. The cross-sectional shape of the first inner surface 73A is, for example, formed as an arc shape extending on the same circumference as the inner surface of the first lower hem portion 71. The cross-sectional shape of the second inner surface 73B is, for example, formed as an arc shape curved along the outer peripheral surface of the second outer member 32. The cross-sectional shape of the second inner surface 73B is, for example, formed as an arc shape extending on the same circumference as the inner surface of the arm portion 44b. The cross-sectional shape of the second inner surface 73B is, for example, formed as an arc shape extending on the same circumference as the inner surface of the second lower hem portion 72.

[0223] The top end of the partition 70 is located on the opposite side of the covering portion 43, separated from the center of the first outer member 22 and the center of the second outer member 32, in the Y-axis direction. For example, in the Y-axis direction, the shortest distance between the top end of the partition 70 and the covering portion 43 is shorter than the shortest distance between the first end 45 of the arm portion 44a and the covering portion 43. That is, in the Y-axis direction, the length of the partition 70 is shorter than the length of the arm 44a.

[0224] The top end of the partition 70 has a first top end 75 and a second top end 76 extending in a direction different from the first top end 75. The top end of the partition 70 is formed such that it branches from the middle portion 73 into two first top end 75 and second top end 76. The first top end 75 and the second top end 76 extend from the middle portion 73 toward a direction separating from the covering portion 43 and in opposite directions to each other in the arrangement direction X.

[0225] The first top end portion 75 covers a portion of the outer peripheral surface of the first outer member 22, constituting the first receiving portion 81. The cross-sectional shape of the first top end portion 75 is, for example, formed into an arc shape curved along the outer peripheral surface of the first outer member 22. The cross-sectional shape of the first top end portion 75 is, for example, formed into an arc shape extending on the same circumference as the arm portion 44a. The second top end portion 76 covers a portion of the outer peripheral surface of the second outer member 32, constituting the second receiving portion 82. The cross-sectional shape of the second top end portion 76 is, for example, formed into an arc shape curved along the outer peripheral surface of the second outer member 32. The cross-sectional shape of the second top end portion 76 is, for example, formed into an arc shape extending on the same circumference as the arm portion 44b. When viewed from the length direction of the first path limiting member 40, the first top end portion 75 and the second top end portion 76 are, for example, formed into arc shapes that convex in opposite directions.

[0226] The length of the first tip 75, that is, the amount by which the first tip 75 protrudes from the middle part 73, is, for example, equal to the length of the second tip 76, that is, the amount by which the second tip 76 protrudes from the middle part 73. Furthermore, in this specification, the term "equal" includes not only cases where they are exactly equal, but also cases where the comparison objects differ slightly due to dimensional tolerances, etc.

[0227] In the first path limiting member 40, when viewed from the length direction of the first path limiting member 40, the circumferential tip 75a of the first tip portion 75 and the circumferential tip 76a of the second tip portion 76 are each curved. In other words, the cross-sectional shape of the tip 75a of the first tip portion 75 and the tip 76a of the second tip portion 76 is formed into a curved shape. In this embodiment, the cross-sectional shape of the tips 75a and 76a is formed into a semi-circular shape.

[0228] The first top portion 75 and the first end portion 45 are disposed opposite each other in the circumferential direction of the first receiving portion 81. The first top portion 75 and the first end portion 45 are disposed separately from each other in the circumferential direction of the first receiving portion 81 through the first receiving opening 83. In other words, in the circumferential direction of the first receiving portion 81, the gap between the first top portion 75 and the first end portion 45 constitutes the first receiving opening 83. For example, the first receiving opening 83 is formed by the top end 75a of the first top portion 75 and the top end 45a of the first end portion 45. The opening width of the first receiving opening 83, that is, the shortest distance between the first top portion 75 and the first end portion 45, is less than the outer diameter of the first outer member 22. The opening width of the first receiving opening 83 is, for example, less than the outer diameter of the first outer member 22 and less than the outer diameter of the second outer member 32. The first outer member 22 is inserted into the first receiving opening 83 in a direction orthogonal to the length direction of the first path limiting member 40.

[0229] The second top portion 76 and the second end portion 46 are disposed opposite each other in the circumferential direction of the second receiving portion 82. The second top portion 76 and the second end portion 46 are separated from each other in the circumferential direction of the second receiving portion 82 by a second receiving opening 84. In other words, in the circumferential direction of the second receiving portion 82, the gap between the second top portion 76 and the second end portion 46 constitutes the second receiving opening 84. For example, the second receiving opening 84 is formed by the top end 76a of the second top portion 76 and the top end 46a of the second end portion 46. The opening width of the second receiving opening 84, i.e., the shortest distance between the second top portion 76 and the second end portion 46, is less than the outer diameter of the second outer member 32. The opening width of the second receiving opening 84 is, for example, less than the outer diameter of the first outer member 22 and less than the outer diameter of the second outer member 32. The opening width of the second receiving opening 84 is, for example, equal to the opening width of the first receiving opening 83. The second external component 32 is inserted into the second receiving port 84 in a direction orthogonal to the length direction of the first path limiting component 40.

[0230] In the cross-section of the first path limiting member 40, the tangent passing through the first end 45 of the central axis C1 of the first storage portion 81 is designated as tangent T3, and the tangent passing through the first top end 75 of the central axis C1 is designated as tangent T4. Furthermore, in the cross-section of the first path limiting member 40, the tangent passing through the second end 46 of the central axis C2 of the second storage portion 82 is designated as tangent T5, and the tangent passing through the second top end 76 of the central axis C2 is designated as tangent T6. The opening angle θ1 of the first storage opening 83 in the circumferential direction of the first storage portion 81 is, for example, in the range of 60° to 120°. The opening angle θ2 of the second storage opening 84 in the circumferential direction of the second storage portion 82 is, for example, in the range of 60° to 120°. In this embodiment, the opening angles θ1 and θ2 are equal when the first outer component 22 and the second outer component 32 are not housed in the first storage portion 81 and the second storage portion 82, respectively. Furthermore, the opening angle θ1 of the first storage opening 83 is the angle centered on the central axis C1 of the first storage portion 81, i.e., the angle formed by tangents T3 and T4. Similarly, the opening angle θ2 of the second storage opening 84 is the angle centered on the central axis C2 of the second storage portion 82, i.e., the angle formed by tangents T5 and T6.

[0231] The partition 70 has a first protrusion 77 protruding from the inner surface of the first top end 75 and a second protrusion 78 protruding from the inner surface of the second top end 76. The first protrusion 77 protrudes from the inner surface of the top end 75a of the first top end 75. The first protrusion 77 protrudes toward a first outer member 22 housed inside the first housing portion 81. The first protrusion 77, for example, contacts the outer surface of the first outer member 22. The second protrusion 78 protrudes from the inner surface of the top end 76a of the second top end 76. The second protrusion 78 protrudes toward a second outer member 32 housed inside the second housing portion 82. The second protrusion 78, for example, contacts the outer surface of the second outer member 32.

[0232] The cross-sectional shapes of the first protrusion 77 and the second protrusion 78 are, for example, curved. The cross-sectional shapes of the first protrusion 77 and the second protrusion 78 are, for example, semi-circular. Viewed from the longitudinal direction of the first path limiting member 40, the surface of the first protrusion 77 is, for example, formed as a smooth, continuous arcuate shape with the surface of the tip 75a of the first tip portion 75. In other words, viewed from the longitudinal direction of the first path limiting member 40, the tip 75a of the first tip portion 75 and the surface of the first protrusion 77 have arcuate surfaces extending on the same circumference. Viewed from the longitudinal direction of the first path limiting member 40, the surface of the second protrusion 78 is, for example, formed as a smooth, continuous arcuate shape with the surface of the tip 76a of the second tip portion 76. In other words, viewed from the longitudinal direction of the first path limiting member 40, the tip 76a of the second tip portion 76 and the surface of the second protrusion 78 have arcuate surfaces extending on the same circumference. The arcuate surface formed by the tip 75a and the first protrusion 77 of the first tip 75 and the arcuate surface formed by the tip 76a and the second protrusion 78 of the second tip 76 are formed in a manner that expands on mutually different circumferences. The outer diameter of the arcuate surface formed by the tip 75a and the first protrusion 77 of the first tip 75 is, for example, equal to the outer diameter of the arcuate surface formed by the tip 76a and the second protrusion 78 of the second tip 76.

[0233] like Figure 12 As shown, the first protrusion 77 and the second protrusion 78 each extend, for example, along the length direction of the first path limiting member 40. The first protrusion 77 and the second protrusion 78 each extend, for example, throughout the entire length of the first path limiting member 40.

[0234] like Figure 11As shown, the first protrusion 77 and the first projection 47 press against the first outer member 22 from the outside, for example. The first outer member 22 is elastically held inside the first receiving portion 81 by the first protrusion 77, the first projection 47, and the covering portion 43. The second protrusion 78 and the second projection 48 press against the second outer member 32 from the outside, for example. The second outer member 32 is elastically held inside the second receiving portion 82 by the second protrusion 78, the second projection 48, and the covering portion 43. As a result, the connection between the first path limiting member 40 and the first outer member 22 and the second outer member 32 becomes secure. Therefore, the first path limiting member 40, which is installed on the outer periphery of the first outer member 22 and the second outer member 32, is prevented from moving in the longitudinal direction of the first outer member 22 and the second outer member 32.

[0235] Furthermore, when the first outer component 22 is inserted into the first storage section 81, the opening width of the first storage opening 83 may not return to its original width, i.e., when the first outer component 22 is not inserted (see reference). Figure 12 The width of the first storage opening 83 is sometimes larger than its original width because the elastic deformation of the first storage portion 81, which is about to return to its original shape, is blocked by the first outer member 22. Furthermore, when the first outer member 22 is inserted into the first storage portion 81, the first outer member 22 becomes flexed due to the pressure of the first storage portion 81, and the opening width of the first storage opening 83 sometimes returns to its original width. That is, the opening width of the first storage opening 83 when the first outer member 22 is inserted into the first storage portion 81 becomes based on the rigidity and flexibility of the first outer member 22 and the first storage portion 81. Similarly, the opening width of the second storage opening 84 when the second outer member 32 is inserted into the second storage portion 82 becomes based on the rigidity and flexibility of the second outer member 32 and the second storage portion 82.

[0236] In this embodiment, with the first outer component 22 inserted into the first storage portion 81 and the second outer component 32 inserted into the second storage portion 82, the opening widths of the first storage opening 83 and the second storage opening 84 are different. Furthermore, with the first outer component 22 and the second outer component 32 respectively stored in the first storage portion 81 and the second storage portion 82, the opening angles θ1 of the first storage opening 83 and the second storage opening 84 are different. Specifically, the opening angle θ1 of the first storage opening 83 is larger than the opening angle θ2 of the second storage opening 84. This is because, for example, the outer diameter of the first outer component 22 is larger than the outer diameter of the second outer component 32.

[0237] The first path limiting member 40 is configured, for example, to individually snap onto the first wire harness 11A and the second wire harness 12A. For example, the first wire harness 11A and the second wire harness 12A can be installed or removed from the first path limiting member 40 at different times. For example, the first path limiting member 40 can first hold only the first wire harness 11A and then hold the second wire harness 12A.

[0238] The effects of the fifth embodiment will be explained.

[0239] (21) In the first path limiting member 40, the division between the portion where the first outer member 22 is disposed and the portion where the second outer member 32 is disposed is performed by the partition 70. Therefore, the workability when assembling the first outer member 22 and the second outer member 32 in the first path limiting member 40 can be improved.

[0240] (22) The top end of the partition 70 is configured to have a first top end 75 and a second top end 76. The first top end 75 covers a portion of the outer periphery of the first outer member 22, and the second top end 76 extends in a direction different from the first top end 75 and covers a portion of the outer periphery of the second outer member 32. That is, the top end of the partition 70 is configured to have two forks, namely the first top end 75 and the second top end 76. As a result, for example, the length of the first top end 75 and the length of the second top end 76 can be set separately. That is, the amount of protrusion of the first top end 75 from the middle portion 73 and the amount of protrusion of the second top end 76 from the middle portion 73 can be set separately. Therefore, the range of the outer periphery of the first outer member 22 covered by the first top end 75 and the range of the outer periphery of the second outer member 32 covered by the second top end 76 can be set separately. In other words, the opening width of the first storage opening 83 and the opening width of the second storage opening 84 can be set separately. Therefore, the opening width of the first storage opening 83 and the opening width of the second storage opening 84 can be set separately, such that, for example, the first outer component 22 and the second outer component 32 have opening widths that are difficult to detach from the first storage part 81 and the second storage part 82, respectively.

[0241] Furthermore, the opening angle θ1 of the first storage opening 83 and the opening angle θ2 of the second storage opening 84 can be set independently. Thus, for example, the insertion angle when the first outer component 22 is inserted into the first storage section 81 and the insertion angle when the second outer component 32 is inserted into the second storage section 82 can be set independently.

[0242] (23) The partition 70 has a first protrusion 77 protruding from the inner surface of the first top end portion 75 toward the first outer member 22. Therefore, the first protrusion 77 can be used to prevent the first outer member 22 from detaching from the first path limiting member 40. Additionally, the partition 70 has a second protrusion 78 protruding from the inner surface of the second top end portion 76 toward the second outer member 32. Therefore, the second protrusion 78 can be used to prevent the second outer member 32 from detaching from the first path limiting member 40.

[0243] (24) The first outer component 22 is larger than the second outer component 32. The first path limiting component 40, together with the first outer component 22 and the second outer component 32, which have different sizes, limits the paths of the first wire harness 11A and the second wire harness 12A. That is, even if the first outer component 22 and the second outer component 32 have different sizes, the paths of multiple wire harnesses can be limited by one first path limiting component 40. This helps to reduce the number of components in the composite wire harness 10C.

[0244] (25) The first wiring harness 11A has two first wires 21 constituting a DC circuit. Additionally, the second wiring harness 12A has three second wires 31 constituting a three-phase circuit. The paths of these first wiring harnesses 11A and second wiring harnesses 12A are restricted by a first path limiting member 40. Thus, the paths of the first wiring harness 11A and second wiring harness 12A used, for example, in a four-wheel drive (4WD) vehicle V can be restricted using a first path limiting member 40. Therefore, it is possible to reduce the number of components in the composite wiring harness 10C.

[0245] Furthermore, in existing structures, for example, when the vehicle V's drive mode is front-wheel drive or rear-wheel drive (2WD), a wiring harness with only the first wiring harness 11A (of the first wiring harness 11A and the second wiring harness 12A) is used. Additionally, in existing structures, when the vehicle V's drive mode is four-wheel drive (4WD), a wiring harness with two first wires 21 and three second wires 31 housed together inside an external component is used. This external component is, for example, a metal tube. Thus, in existing structures, the wiring harnesses for 2WD and 4WD have completely different structures. Therefore, the wiring harnesses for 2WD and 4WD are manufactured using completely different manufacturing methods. In contrast, in the structure of this embodiment, by combining the 2WD wiring harness, i.e., the first wiring harness 11A, with the second wiring harness 12A having three second wires 31, a 4WD wiring harness can be constructed. Therefore, depending on whether the second wire harness 12A is combined with the first wire harness 11A, both a 2WD wire harness and a 4WD wire harness can be constructed. In other words, the first wire harness 11A can be shared by the 2WD wire harness and the 4WD wire harness (i.e., the composite wire harness 10C). Therefore, the first wire harness 11A can be manufactured using a common manufacturing method in both the 2WD wire harness and the 4WD wire harness.

[0246] Furthermore, when combining the first wire harness 11A with the second wire harness 12A, the first wire harness 11A and the second wire harness 12A can be properly arranged side by side by using the first path limiting member 40.

[0247] The above embodiments can be implemented with the following modifications. The above embodiments and the following modifications can be combined with each other within the scope of technical non-contradiction.

[0248] (A variation of the third embodiment)

[0249] In the third embodiment described above, the second path limiting member 50 is configured to be longer than the first path limiting member 40 in the length direction of the first wire harness 11. However, this is not a limitation; the first path limiting member 40 may also be configured to be longer than the second path limiting member 50. According to this structure, the first path limiting member 40 restricts the paths of the first wire harness 11 and the second wire harness 12 over a wide range, and the second path limiting member 50 is provided at locations in the first wire harness 11 where more robust path restriction is required, thereby achieving appropriate path restriction.

[0250] In the third embodiment described above, the first insertion port 42 of the first path limiting member 40 and the second insertion port 52 of the second path limiting member 50 open in the same direction along the Y-axis. However, in other cases, the first insertion port 42 and the second insertion port 52 may be configured to face opposite directions.

[0251] • In the third embodiment described above, in the circumferential direction of the first outer member 22, the first end 45 of the first main body 41 extends longer than the third end 53 of the second main body 51. However, it is not limited to this, and the third end 53 may also extend longer than the first end 45 in the circumferential direction of the first outer member 22.

[0252] In the third embodiment described above, the second path limiting member 50 may be installed not only on the first outer member 22 but also on the outer periphery of the second outer member 32. The second path limiting member 50, installed on the outer periphery of the second outer member 32, is disposed inside the first path limiting member 40. With this structure, the path of the second wiring harness 12 can be more appropriately limited. Furthermore, it contributes to improving the durability of the second outer member 32.

[0253] • In the second path limiting member 50, a protrusion may also be provided that protrudes from the inner surface of the second main body 51 and contacts the outer surface of the first outer member 22. With such a structure, both the third protrusion 55 and the protrusion can contact the outer surface of the first outer member 22, thereby suppressing the swaying of the second path limiting member 50.

[0254] • In the second path limiting member 50, a groove extending along the length direction may also be provided on the outer peripheral surface of the second main body 51. According to this structure, the second main body 51 can easily deform outwards from the groove, thereby easily enlarging the second insertion port 52. As a result, this contributes to improving the assemblability of the second path limiting member 50.

[0255] • In the second path limiting member 50, the shape of the second main body 51 is not limited to an arc shape, but can be deformed into, for example, an elliptical arc shape.

[0256] • In the third embodiment described above, the second path limiting member 50 is made of a synthetic resin material, but it is not limited to this and may also be made of, for example, a metal material.

[0257] • In the third embodiment described above, the second path limiting member 50 is made harder than the first outer member 22. However, it is not limited to this. The second path limiting member 50 may also be configured to have the same hardness as the first outer member 22 or be softer than the first outer member 22.

[0258] (A variation of the fourth embodiment)

[0259] In the fourth embodiment described above, the third path limiting member 60 is made of a metallic material. However, it can also be made of a colored synthetic resin material, for example. With this structure, the third path limiting member 60 can be set to a desired color even without surface coating. Therefore, by setting the color of the third path limiting member 60 to a color that allows the operator to identify that the composite wiring harness 10B includes the first wire 21, which is a high-voltage wire, it is possible to draw the operator's attention and prevent them from mistakenly cutting the first wire 21. Furthermore, by setting the third path limiting member 60 to the same color as the first path limiting member 40, the operator can more appropriately identify that the composite wiring harness 10B includes a high-voltage wire. Additionally, the material for the third path limiting member 60 can be, for example, synthetic resins such as polypropylene, polyamide, or polyoxymethylene. The third path limiting member 60 can be formed, for example, by known methods such as extrusion molding or injection molding.

[0260] Furthermore, even when the third path limiting member 60 is made of synthetic resin, it is desirable for the third path limiting member 60 to be harder than the first outer member 22 and the second outer member 32. However, the material of the third path limiting member 60 does not necessarily have to be a material harder than the materials of the first outer member 22 and the second outer member 32. That is, the material of the third path limiting member 60 can be either a material harder or softer than the materials of the first outer member 22 and the second outer member 32. Alternatively, the material of the third path limiting member 60 can also be the same as the materials of the first outer member 22 and the second outer member 32.

[0261] • In the fourth embodiment described above, the third path limiting member 60 is configured to be shorter than the first path limiting member 40 in the length direction of the first path limiting member 40. However, it is not limited to this and the third path limiting member 60 may also be configured to be longer than the first path limiting member 40.

[0262] • In the fourth embodiment described above, the first insertion port 42 of the first path limiting member 40 and the third insertion port 62 of the third path limiting member 60 open in the same direction along the Y-axis. However, in other cases, for example, the first insertion port 42 and the third insertion port 62 may be configured to face opposite directions.

[0263] In the fourth embodiment described above, the fifth end 65 extends longer than the first end 45 of the first main body 41 in the circumferential direction of the first outer member 22. However, this is not a limitation; the first end 45 may also extend longer than the fifth end 65 in the circumferential direction of the first outer member 22. Furthermore, the second end 46 may extend longer than the sixth end 66 in the circumferential direction of the second outer member 32. That is, the opening width of the third insertion port 62 in the arrangement direction X may be configured to be wider than the opening width of the first insertion port 42 in the arrangement direction X.

[0264] • In the third path limiting member 60, a groove extending along the length direction may also be provided on the outer peripheral surface of the third main body 61. According to this structure, the third main body 61 can be easily deformed outwards from the groove, thereby easily enlarging the third insertion port 62. As a result, this contributes to improving the assemblability of the third path limiting member 60.

[0265] • In the fourth embodiment described above, the third path limiting member 60 is made harder than the first outer member 22 and the second outer member 32. However, it is not limited to this; the third path limiting member 60 may also be configured to have the same hardness as the first outer member 22 and the second outer member 32, or be softer than the first outer member 22 and the second outer member 32.

[0266] (A variation of the fifth embodiment)

[0267] • The structure of the first path limiting member 40 in the fifth embodiment described above can be appropriately deformed.

[0268] ·For example Figure 13 As shown, the portion of the covering portion 43 that connects one end of the first hem portion 71 and one end of the second hem portion 72 can also be omitted. In this case, the first path limiting member 40 is formed, for example, as a C-shaped first storage portion 81 and a C-shaped second storage portion 82 connected by the middle portion 73 of the separating portion 70. In addition, in the first path limiting member 40 of this modified example, the space S1 between the first hem portion 71 and the second hem portion 72 opens in the Y-axis direction away from the middle portion 73. Therefore, when a component separate from the first path limiting member 40 is provided near the first path limiting member 40, interference between the separate component and the first path limiting member 40 can be appropriately suppressed, for example, by retracting the separate component into the space S1.

[0269] • In the first path limiting member 40 of the fifth embodiment described above, the first storage portion 81 and the second storage portion 82 may be formed with different shapes. For example, when the first outer member 22 and the second outer member 32 are not inserted, the cross-sectional shape of the first storage portion 81 and the cross-sectional shape of the second storage portion 82 may also be formed with different shapes.

[0270] • In the partition 70 of the fifth embodiment described above, the lengths of the first top portion 75 and the second top portion 76 may be set to different lengths. That is, the amount by which the first top portion 75 protrudes from the middle portion 73 and the amount by which the second top portion 76 protrudes from the middle portion 73 may be set to different sizes.

[0271] • In the partition 70 of the fifth embodiment described above, the outer diameter of the arcuate surface formed by the tip 75a of the first tip 75 and the first protrusion 77 and the outer diameter of the arcuate surface formed by the tip 76a of the second tip 76 and the second protrusion 78 may be set to different sizes.

[0272] • In the partition 70 of the fifth embodiment described above, the first top end portion 75 and the second top end portion 76 may be formed with different shapes. For example, the cross-sectional shape of the first top end portion 75 and the cross-sectional shape of the second top end portion 76 may be formed with different shapes.

[0273] Alternatively, the first protrusion 77 in the fifth embodiment described above may be positioned circumferentially in the first receiving portion 81 at a position further away from the first receiving opening 83 than the tip 75a of the first tip portion 75. Furthermore, the second protrusion 78 may be positioned circumferentially in the second receiving portion 82 at a position further away from the second receiving opening 84 than the tip 76a of the second tip portion 76.

[0274] • In the partition 70 of the fifth embodiment described above, the base end of the partition 70 is configured to branch into a first hem portion 71 and a second hem portion 72, but it is not limited to this. For example, the base end of the partition 70 may be modified to a structure that does not branch into two, that is, a structure that converges into one as in the middle portion 73. For example, the middle portion 73 may be modified to extend to the covering portion 43.

[0275] • In the partition 70 of the fifth embodiment described above, the cross-sectional shapes of the first inner surface 73A and the second inner surface 73B of the middle part 73 are not limited to an arc shape, for example, they can be deformed into a shape that extends in a straight line along the Y-axis direction.

[0276] • In the second embodiment described above, the first protrusion 49a and the second protrusion 49b may also be partially provided in the length direction of the first path limiting member 40. Additionally, in the fifth embodiment described above, the first protrusion 77 and the second protrusion 78 may also be partially provided in the length direction of the first path limiting member 40.

[0277] • In the second embodiment described above, at least one of the first protrusion 49a and the second protrusion 49b may be omitted. Additionally, in the fifth embodiment, at least one of the first protrusion 77 and the second protrusion 78 may be omitted.

[0278] In the first and fourth embodiments described above, the unevenness of the outer peripheral surface of the first outer member 22 engages with the unevenness of the outer peripheral surface of the second outer member 32 in the portion held in the first path limiting member 40. However, this is not particularly limited to this configuration, and the outer peripheral surfaces of the first outer member 22 and the second outer member 32 may be configured to merely contact each other without their unevenness engaging.

[0279] • In the second and fifth embodiments described above, a third path limiting member 60 may also be provided on the outside of the first path limiting member 40.

[0280] In the first to third embodiments and the fifth embodiment described above, the first path limiting member 40 is made of a synthetic resin material. However, it can also be made of a metal material, for example. According to this structure, the first path limiting member 40, made of a metal material, can effectively isolate heat transferred from the outside to the first outer member 22 and the second outer member 32. Furthermore, in the third embodiment, when the first path limiting member 40 is made of metal, the second path limiting member 50 made of synthetic resin can suppress contact between the metal first path limiting member 40 and the first outer member 22. As a result, wear on the first outer member 22 caused by contact with the metal first path limiting member 40 can be suppressed.

[0281] • In the above embodiments, the first path limiting member 40 is made harder than the first outer member 22 and the second outer member 32. However, it is not limited to this, and the first path limiting member 40 may also be configured to have the same hardness as the first outer member 22 and the second outer member 32, or be softer than the first outer member 22 and the second outer member 32.

[0282] In the above embodiments, the first protrusion 47 and the second protrusion 48 may be partially provided along the length of the first path limiting member 40. Furthermore, in the third embodiment described above, the third protrusion 55 may be partially provided along the length of the second path limiting member 50. Additionally, in the fourth embodiment described above, the fourth protrusion 67 may be partially provided along the length of the third path limiting member 60.

[0283] Alternatively, the first protrusion 47 and the second protrusion 48 of each of the above embodiments may be positioned circumferentially on the first path limiting member 40 at a location farther from the first insertion port 42 than the tip 45a of the first end 45 and the tip 46a of the second end 46. Furthermore, the third protrusion 55 of each of the third embodiments may be positioned circumferentially on the second path limiting member 50 at a location farther from the second insertion port 52 than the tip 53a of the third end 53 and the tip 54a of the fourth end 54. Additionally, the fourth protrusion 67 of each of the fourth embodiments may be positioned circumferentially on the third path limiting member 60 at a location farther from the third insertion port 62 than the tip 65a of the fifth end 65 and the tip 66a of the sixth end 66.

[0284] In each of the above embodiments, at least one of the first protrusion 47 and the second protrusion 48 may be omitted. Furthermore, in the third embodiment described above, at least one of the third protrusion 55 at the third end 53 and the third protrusion 55 at the fourth end 54 may be omitted. Additionally, in the fourth embodiment described above, at least one of the fourth protrusion 67 at the fifth end 65 and the fourth protrusion 67 at the sixth end 66 may be omitted.

[0285] In the first path limiting member 40 of the above embodiments, a groove extending along the length direction may also be provided on the outer peripheral surface of the first main body 41. According to this structure, the first main body 41 can easily deform outward from the groove, thereby easily enlarging the first insertion port 42. As a result, it can help improve the assemblability of the first path limiting member 40.

[0286] • In the first to fourth embodiments described above, the first wire harness 11 may be modified into the first wire harness 11A, and the second wire harness 12 may be modified into the second wire harness 12A.

[0287] In the above embodiments, the first wire 21 is configured as a high-voltage wire and the second wire 31 is configured as a low-voltage wire, but it is not limited to this. For example, the first wire 21 and the second wire 31 can each be configured as a high-voltage wire or a low-voltage wire.

[0288] The embodiments and variations disclosed herein should be considered illustrative in all respects and not restrictive. The scope of the invention is defined not by the foregoing, but by the claims, and is intended to include all variations within the scope of the same conception as the claims.

[0289] ·like Figure 3 As shown, the opening width of the first insertion port 42 of the first path limiting member 40 can also be larger than the outer diameter of the first outer member 22 and larger than the outer diameter of the second outer member 32.
