Detailed Implementation
[0009] [Description of embodiments of this disclosure] First, the implementation methods of this disclosure are listed and explained. The wire harness disclosed herein, [1] The wire harness body comprises a wire member and an mounting member. The wire harness body comprises: a wire member; an outer member covering the outer periphery of the wire member; and a first path limiting member mounted on the outer periphery of the outer member to limit the path of the outer member. The mounting member is mounted on the outer periphery of a portion of the length direction of the first path limiting member. The first path limiting member has an insertion port that opens in a direction orthogonal to the length direction of the first path limiting member and extends throughout the length direction of the first path limiting member. The mounting member has a covering portion that covers the outer periphery of the first path limiting member. The covering portion has a through hole that extends from the outer periphery to the inner periphery of the covering portion. The wire harness comprises a filler that is filled between the wire harness body and the covering portion through the through hole.
[0010] According to this structure, the wire harness body passing through the inner side of the covering portion is pressed against the covering portion by the filler material filled between the covering portion and the wire harness body. This suppresses the shaking of the covering portion and the wire harness body.
[0011] [2] The filler enters the insertion port, and the filler is located between the outer peripheral surface of the outer component and the inner peripheral surface of the covering part. According to this structure, the outer component and the first path limiting member can be pressed into the covering portion using filler that is filled between the outer component and the covering portion. Furthermore, because the filler enters the insertion port of the first path limiting member, the circumferential rotation of the first path limiting member can be suppressed by the filler. Additionally, because the filler enters the insertion port of the first path limiting member, the covering portion can be radially miniaturized compared to a structure where the filler contacts the outer peripheral surface of the first path limiting member.
[0012] [3] The through hole is opposite the insertion port in the radial direction of the covering portion. According to this structure, the filler can be properly inserted into the insertion port. [4] The through hole faces the outer peripheral surface of the first path limiting member, and the filler is located between the outer peripheral surface of the first path limiting member and the inner peripheral surface of the covering portion. According to this structure, the first path limiting member can be pressed into the covering portion using the filler filled between the first path limiting member and the covering portion.
[0013] [5] A portion of the filler enters the interior of the through hole. According to this structure, the through hole can be sealed with the filler. [6] The mounting member includes: a main body portion that restricts the path of the outer mounting member; a receiving portion disposed at an end of the main body portion in the length direction of the wire harness body; and a cover portion that, together with the receiving portion, covers the entire circumference of the first path restricting member, wherein the receiving portion and the cover portion constitute the covering portion. According to this structure, the receiving portion and the cover portion can be used to form a covering portion that covers the outer circumference of the first path restricting member.
[0014] [7] The through hole is provided in the cover. According to this structure, filler can be filled through the through hole provided in the cover. [8] The filler is made of resin material. According to this structure, the wire harness body can be properly pressed into the covering part using the filler made of resin material.
[0015] [9] The mounting member is a second path limiting member installed on the outer periphery of the outer component and limiting the path of the outer component. The covering part is provided at the end of the second path limiting member in the length direction and covers the outer periphery of the end of the first path limiting member in the length direction.
[0016] According to this structure, the covering portion is provided at the end of the second path limiting member in the longitudinal direction, covering the outer periphery of the end of the first path limiting member in the longitudinal direction. Therefore, the first path limiting member and the second path limiting member are connected in the longitudinal direction. Thus, the path of the outer component is continuously limited by the first path limiting member and the second path limiting member.
[0017]
[10] The first path limiting member restricts the path of the straight part, the straight part being the straight portion in the path of the wire harness body, and the second path limiting member restricts the path of the bent part, the bent part being the bent portion in the path of the wire harness body.
[0018] According to this structure, the path of the straight portion is restricted by a first path limiting member, and the path of the bent portion is restricted by a second path limiting member. Thus, deviations of the straight and bent portions of the wire harness from their desired paths can be continuously prevented.
[0019] [Details of the embodiments of this disclosure] The following is a reference to the appendix. Figure 1 Specific examples of the wiring harnesses disclosed herein will be described below. In the accompanying drawings, for ease of explanation, sometimes a portion of the structure is shown enlarged or simplified. Furthermore, the dimensional ratios of the various parts may differ in the accompanying drawings. Additionally, the term "orthogonal" in this specification includes not only strictly orthogonal cases but also cases that are substantially orthogonal to the extent that they serve the functions and effects of this embodiment.
[0020] Furthermore, in this specification, "opposite" refers to a position where surfaces or components are directly opposite each other, including not only positions where they are completely opposite each other, but also positions where they are partially opposite each other. Additionally, "opposite" in this specification includes both cases where a component independent of the two parts is interposed between the two parts, and cases where nothing is placed between the two parts.
[0021] In addition, the term "ring" as used in this specification sometimes refers to any structure forming a ring, or a continuous shape without ends, and a generally ring-shaped structure with gaps, such as a C-shape. Furthermore, the shape of "ring" includes circles, ellipses, and polygons with pointed or rounded corners, but is not limited to these.
[0022] (Overall structure of wire harness 10) Figure 1 The wiring harness 10 shown is, for example, mounted on a vehicle V such as a hybrid vehicle or an electric vehicle. The wiring harness 10 electrically connects two or more on-board devices to each other. On-board devices are electrical devices mounted on the vehicle V. For example, the wiring harness 10 electrically connects an inverter M1 located at the front of the vehicle V and a high-voltage battery M2 located at the rear of the vehicle V, beyond the inverter M1. The wiring harness 10 is, for example, formed as a long strip extending in the longitudinal direction of the vehicle V. For example, the wiring harness 10 is laid out in the vehicle V such that its middle portion, along its length, passes under the floor of the vehicle V or outside the passenger compartment.
[0023] Inverter M1 is connected, for example, to an electric motor (not shown) that powers the drive wheels of the vehicle. Inverter M1 generates alternating current from the direct current (DC) of high-voltage battery M2 and supplies this AC power to the electric motor. High-voltage battery M2 is, for example, a battery capable of supplying several hundred volts.
[0024] The wire harness 10 has a wire harness body 11. The wire harness body 11 has a wire member 20 and a cylindrical outer member 30 that surrounds the outer periphery of the wire member 20. In addition, the wire harness body 11 has a first path limiting member 40 (see reference) that is mounted on the outer periphery of the outer member 30 and limits the path of the outer member 30. Figure 2The wiring harness 10 has connectors C1 and C2 installed at both ends of the wire member 20. One end of the wire member 20 in the longitudinal direction is connected to the inverter M1 via connector C1, and the other end of the wire member 20 in the longitudinal direction is connected to the high-voltage battery M2 via connector C2.
[0025] like Figure 2 As shown, the wire harness 10 has a second path limiting member 50 mounted on the outer periphery of the outer component 30. The first path limiting member 40 and the second path limiting member 50 limit the routing path of the wire harness body 11. Furthermore, in Figure 1 The illustrations of the first path limiting member 40 and the second path limiting member 50 are omitted.
[0026] (Structure of electrical component 20) like Figure 3 and Figure 4 As shown, the wire member 20 has, for example, one or more wires 21, which are two wires in this embodiment, and a braided member 25 that surrounds the outer circumference of the multiple wires 21.
[0027] Each wire 21 is a covered wire having a core wire 22 and an insulating covering 23. The core wire 22 is conductive, and the insulating covering 23 surrounds the outer periphery of the core wire 22 and is insulating. Each wire 21 is, for example, a high-voltage wire capable of handling high voltage and high current. Each wire 21 can be, for example, an unshielded wire without its own electromagnetic shielding structure, or a shielded wire with its own electromagnetic shielding structure. In this embodiment, each wire 21 is an unshielded wire.
[0028] As the core wire 22, for example, a stranded wire composed of multiple metal wires twisted together or a single-core wire composed of a single conductor can be used. As a single-core wire, for example, a cylindrical conductor composed of a single metal rod with a solid internal structure or a cylindrical conductor with a hollow internal structure can be used. As the core wire 22, stranded wires, cylindrical conductors, and cylindrical conductors can also be used in combination. As the material of the core wire 22, for example, copper-based or aluminum-based metal materials can be used.
[0029] The insulating covering portion 23, for example, covers the entire circumference of the outer periphery of the core wire 22. The insulating covering portion 23 is, for example, made of an insulating resin material. The cross-sectional shape of each wire 21, which is the shape of the cross section formed by cutting the wire 21 with a plane orthogonal to the length direction of each wire 21, can be any shape. For example, the cross-sectional shape of each wire 21 can be formed as a circle, a semi-circle, a polygon, a square, a flat shape, etc. In this embodiment, the cross-sectional shape of each wire 21 is formed as a circle.
[0030] The braided member 25 is, for example, formed as a cylindrical shape that surrounds the outer circumference of the multiple wires 21. The braided member 25 can be, for example, a braided wire made of multiple metal wires, or a braided wire made of a combination of metal wires and resin wires. The material of the metal wires can be, for example, copper-based, aluminum-based, or other metal materials. Although not shown in the figure, the two ends of the braided member 25 in the longitudinal direction are, for example, at connectors C1 and C2 (see reference). Figure 1 Grounding in, etc.
[0031] (Structure of external component 30) The outer casing 30 is formed into a cylindrical shape that surrounds the entire circumference of the wire component 20. In this embodiment, the outer casing 30 is formed into a cylindrical shape. For example, a circumferential wall is continuously formed throughout the entire circumference of the outer casing 30. For example, the outer casing 30 completely seals the interior circumferentially. For example, the outer casing 30 has the function of protecting the wire component 20 from flying objects and water droplets.
[0032] The outer component 30 is flexible and can be easily bent. Examples of flexible outer components 30 include resin corrugated tubes and rubber waterproof caps. In this embodiment, the outer component 30 is a resin corrugated tube with a corrugated shape whose diameter repeatedly increases and decreases along the length of the outer component 30. That is, the outer component 30 of this embodiment has a corrugated structure in which a large-diameter portion 31 and a small-diameter portion 32 with a diameter smaller than the large-diameter portion 31 are alternately connected along the length of the outer component 30. The large-diameter portion 31 and the small-diameter portion 32 are each, for example, formed as an annulus around the circumference of the outer component 30. As the material for the outer component 30, synthetic resins such as polyolefin, polyamide, polyester, and ABS resin can be used. Furthermore, in... Figures 1-3 For the sake of simplicity in the accompanying drawings, the external component 30 is shown in a simplified manner.
[0033] (Structure of the first path limiting member 40 and the second path limiting member 50) like Figure 2 and Figure 3 As shown, the first path limiting member 40 and the second path limiting member 50 each hold the outer member 30. The first path limiting member 40 and the second path limiting member 50 are, for example, more rigid than the outer member 30. The first path limiting member 40 and the second path limiting member 50 each have a rigidity that makes them less prone to bending in a direction orthogonal to the length direction of the wire harness body 11 compared to the outer member 30. Therefore, the first path limiting member 40 and the second path limiting member 50 each restrict the path of the wire harness body 11. For example, the first path limiting member 40 and the second path limiting member 50 each assist the outer member 30 so that the wire harness body 11 does not deviate from the desired path due to its own weight or other factors.
[0034] like Figure 2 As shown, the first path limiting member 40 is partially provided along the length of the wire harness body 11. The first path limiting member 40 is, for example, mounted on the outer periphery of the outer component 30 in a straight section 11A, which is a straight portion in the path of the wire harness body 11. The first path limiting member 40 restricts the path of the wire harness body 11 in the straight section 11A. Here, the straight section 11A is the portion of the wire harness body 11 whose path extends straight in one direction. Furthermore, one or more first path limiting members 40 are provided according to the path of the wire harness body 11.
[0035] The second path limiting member 50 is partially provided along the length of the wire harness body 11. The second path limiting member 50 is installed, for example, on the outer periphery of the outer component 30 at a bend 11B, which is a bent portion in the path of the wire harness body 11. The second path limiting member 50 restricts the path of the wire harness body 11 within the bend 11B. Here, the bend 11B is a portion of the path of the wire harness body 11 that bends away from a straight line. Furthermore, one or more second path limiting members 50 are provided depending on the path of the wire harness body 11.
[0036] (Structure of the first path restriction component 40) like Figure 2 and Figure 4 As shown, the first path limiting member 40 covers a portion of the circumferential periphery of the outer member 30. The first path limiting member 40 is shaped to cover a portion of the circumferential periphery of the outer member 30. The cross-sectional shape of the first path limiting member 40 is generally C-shaped. For example, the first path limiting member 40 covers an area larger than half the circumference of the outer member 30. That is, the first path limiting member 40 covers an area of the outer periphery of the outer member 30 larger than half the total circumference of the outer member 30.
[0037] like Figure 2 As shown, the first path limiting member 40 extends along the length direction of the outer member 30 in the straight section 11A. The first path limiting member 40 is formed, for example, into a shape that extends in a straight line in one direction. The cross-sectional shape of the first path limiting member 40 is, for example, the same throughout the entire length direction of the first path limiting member 40.
[0038] The first path limiting member 40 is made of, for example, metal or resin. In this embodiment, the first path limiting member 40 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used as the material for the first path limiting member 40. The first path limiting member 40 can be manufactured by known manufacturing methods such as extrusion molding and injection molding. In this embodiment, the first path limiting member 40 is an extruded article manufactured by extrusion molding. Therefore, the first path limiting member 40 can be easily manufactured by using an extrusion molding machine that extrudes the raw material of the first path limiting member 40 in the length direction. Furthermore, multiple first path limiting members 40 with different dimensions in the length direction can be manufactured using a single extrusion molding machine. For example, by using a cutting machine to cut the base material formed by a single extrusion molding machine to an arbitrary length, multiple first path limiting members 40 with different dimensions in the length direction can be manufactured.
[0039] like Figure 3 and Figure 4 As shown, the first path limiting member 40 has an insertion port 40X that opens in a direction orthogonal to the length direction of the first path limiting member 40. The insertion port 40X extends throughout the length direction of the first path limiting member 40. The first path limiting member 40 has a first end 41 and a second end 42 forming the insertion port 40X, the first end 41 and the second end 42 being the two circumferential ends of the first path limiting member 40. The first path limiting member 40 has a connecting portion 43 connecting the first end 41 and the second end 42. In other words, the first path limiting member 40 has: a connecting portion 43 formed in such a way as to cover a portion of the circumferential direction of the outer member 30; a first end 41 and a second end 42 provided at the two ends of the connecting portion 43; and an insertion port 40X formed by the first end 41 and the second end 42.
[0040] The connecting portion 43 constitutes a major part of the first path limiting member 40. The radial thickness of the connecting portion 43 is, for example, the same in the circumferential direction of the first path limiting member 40. The cross-sectional shape of the connecting portion 43 is, for example, formed along the outer surface of the outer member 30. The cross-sectional shapes of the first end 41, the second end 42, and the connecting portion 43 are, for example, formed as arcs.
[0041] The first end 41 and the second end 42 are disposed opposite to each other in the circumferential direction of the first path limiting member 40. The first end 41 and the second end 42 are disposed separately from each other in the circumferential direction of the first path limiting member 40 through an insertion opening 40X. In other words, in the circumferential direction of the first path limiting member 40, the gap between the first end 41 and the second end 42 constitutes the insertion opening 40X. Thus, the first path limiting member 40 is formed in a C-shape with the insertion opening 40X in a portion of the circumferential direction of the first path limiting member 40.
[0042] The top ends of the first end 41 and the second end 42 are formed into curved shapes. In this embodiment, the top ends of the first end 41 and the second end 42 are formed into arc shapes.
[0043] The first path limiting member 40 has a protrusion 45 protruding from the inner surface of the first end 41 and a protrusion 46 protruding from the inner surface of the second end 42. Each protrusion 45, 46 protrudes toward an outer member 30 inserted into the first path limiting member 40 and contacts the outer surface of the outer member 30. Each protrusion 45, 46 contacts the outer surface of the large-diameter portion 31 of the outer member 30. For example, the protrusion 45 protrudes from the inner surface of the tip of the first end 41. For example, the protrusion 46 protrudes from the inner surface of the tip of the second end 42. The cross-sectional shape of each protrusion 45, 46 is, for example, formed as a curved shape. In this embodiment, the cross-sectional shape of each protrusion 45, 46 is formed as an arc shape. Each protrusion 45, 46 extends along the length of the first path limiting member 40. For example, each protrusion 45, 46 extends along the entire length of the first path limiting member 40.
[0044] Each protrusion 45, 46 presses against the outer component 30 from the outside. The outer component 30 is elastically held in place by the protrusions 45, 46, and the connecting portion 43. As a result, the connection between the first path limiting member 40 and the outer component 30 becomes secure.
[0045] like Figure 4 As shown, the opening width of the insertion port 40X, that is, the shortest distance between the first end 41 and the second end 42, is less than the outer diameter of the outer component 30. The opening width of the insertion port 40X increases due to the elastic deformation of the first path limiting member 40. For example, the opening width of the insertion port 40X increases as the outer member 30 is inserted into the insertion port 40X from a direction orthogonal to the length direction of the first path limiting member 40. When the outer member 30 is inserted into the interior of the first path limiting member 40, the first path limiting member 40 elastically returns to its original shape. Thus, the opening width of the insertion port 40X is smaller than the outer diameter of the outer member 30, and therefore the first path limiting member 40 is mounted on the outer periphery of the outer member 30.
[0046] (Structure of the second path restriction component 50) like Figure 2 As shown, the second path limiting member 50 is mounted on the outer periphery of the outer member 30 in the bending portion 11B. The second path limiting member 50 extends along the length direction of the outer member 30 in the bending portion 11B. The second path limiting member 50 is bent, for example, along the shape of the bending portion 11B.
[0047] The second path limiting member 50 is made of, for example, metal or resin. In this embodiment, the second path limiting member 50 is made of resin. For example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used as the material for the second path limiting member 50. The second path limiting member 50 can be manufactured, for example, by a known manufacturing method such as injection molding.
[0048] like Figure 2 , Figure 3 as well as Figure 4 As shown, the second path limiting member 50 has a main body portion 51 and a covering portion 52 that covers the end of the first path limiting member 40 in the longitudinal direction. The main body portion 51 is, for example, formed as an elongated shape extending along the longitudinal direction of the outer member 30 in the bending portion 11B. The main body portion 51 extends along the path of the bending portion 11B, for example. That is, the main body portion 51 has a bent shape that bends along the shape of the bending portion 11B. The main body portion 51 covers a portion of the circumferential direction of the outer member 30 in the outer periphery. The main body portion 51 covers, for example, about half of the outer periphery of the outer member 30. For example, the main body portion 51 covers about 180° of the outer periphery of the outer member 30. The main body portion 51 is, for example, generally semi-cylindrical.
[0049] The covering portion 52 is provided at one end of the main body portion 51 in the longitudinal direction. It has a receiving portion 53 integrally formed with one end of the main body portion 51 in the longitudinal direction and a cover portion 54 covering the receiving portion 53.
[0050] The receiving portion 53 covers a portion of the circumferential direction of the first path limiting member 40. The receiving portion 53 also covers a portion of the circumferential direction of the end of the first path limiting member 40 along its length. The receiving portion 53 is shaped to enclose a portion of the circumferential direction of the first path limiting member 40. The cross-sectional shape of the receiving portion 53 is generally semi-cylindrical. For example, the receiving portion 53 is a semi-cylindrical shape with a diameter larger than that of the main body portion 51. The receiving portion 53, for example, covers half of the outer periphery of the first path limiting member 40.
[0051] The cover portion 54, together with the receiving portion 53, covers the entire circumference of the end of the first path limiting member 40. More specifically, the cover portion 54, together with the receiving portion 53, covers the entire circumferential portion of the end of the first path limiting member 40 along its outer periphery. In this embodiment, the cover portion 54 covers a portion of the outer periphery of the first path limiting member 40 and the portion of the outer periphery of the outer fitting member 30 exposed from the insertion port 40X.
[0052] The cover portion 54 has a semi-cylindrical cross-sectional shape. The cover portion 54 is formed into a semi-cylindrical shape with the same diameter as the receiving portion 53. The cover portion 54 covers the portion of the first path limiting member 40 that is not covered by the receiving portion 53 along its outer periphery, and covers half of the first path limiting member 40 along its outer periphery.
[0053] The cover 54 is, for example, separate from the receiving part 53. The receiving portion 53 has a first connecting portion 55. The first connecting portion 55 is provided at both ends of the receiving portion 53 in the circumferential direction. The first connecting portion 55 protrudes radially outward from both ends of the receiving portion 53 in the circumferential direction.
[0054] The cover portion 54 has a second connecting portion 56. The second connecting portion 56 is provided at both ends of the cover portion 54 in the circumferential direction. Each second connecting portion 56 has a groove 57 into which a first connecting portion 55 is inserted. The groove 57 extends along the length direction of the second path limiting member 50. The second connecting portion 56 can be mounted to the first connecting portion 55 by sliding along the length direction of the second path limiting member 50. The first connecting portion 55 and the second connecting portion 56 are connected, thereby keeping the receiving portion 53 and the cover portion 54 inseparable from each other.
[0055] (Structure of filler 60) like Figure 4 As shown, the wire harness 10 includes a filler 60, which fills the space between the covering portion 52 and the wire harness body 11. The filler 60 is injected into the inner circumferential side of the covering portion 52 through a through hole 58 provided in the cover portion 54. The through hole 58 is a hole that extends from the outer circumferential side of the covering portion 52 to the inner circumferential side. The through hole 58 extends through the cover portion 54, for example, radially along the covering portion 52. The through hole 58 is, for example, an elongated hole that extends along the length of the wire harness body 11. The through hole 58 is provided at a position corresponding to the insertion port 40X of the first path limiting member 40. That is, the through hole 58 is opposite the insertion port 40X in the radial direction of the covering portion 52.
[0056] The filler 60 is made of a resin material. Examples of resin materials used in the filler 60 include ethylene copolymers such as EEA (ethylene ethyl acrylate copolymer) and EVA (ethylene-vinyl acetate copolymer), and silicone materials such as one-component liquid silicone rubber. When an ethylene copolymer is used as the filler 60, the filler 60 can be injected into the through hole 58 using an adhesive spray gun. When filling the filler 60, the molten filler 60 is first injected into the inner circumference of the covering portion 52 through the through hole 58. The filler 60 flows into the space between the outer member 30 and the covering portion 52 inside the insertion port 40X of the first path restricting member 40. Furthermore, the viscosity and injection pressure of the filler 60 are set in such a way that the filler 60 does not spread throughout the entire circumference of the small-diameter portion 32 of the outer member 30. As a result, the filler 60 appropriately fills the space between the outer member 30 and the covering portion 52 inside the insertion port 40X.
[0057] The filler 60 cures after being filled between the outer component 30 and the covering portion 52. In the cured state, the filler 60 has a first portion 61 located inside the insertion port 40X, in the space between the outer component 30 and the covering portion 52. The first portion 61 is bonded to the inner peripheral surface of the covering portion 52, the outer peripheral surface of the outer component 30, and the first end 41 and the second end 42 of the first path limiting member 40, respectively. The wire harness body 11, including the outer component 30 and the first path limiting member 40, is pressed against the inner peripheral surface of the covering portion 52 by the pressure of the first portion 61 of the filler 60. Furthermore, it is preferable that the filler 60 has moderate elasticity in the cured state.
[0058] Furthermore, in its cured state, the filler 60 has a second portion 62 that enters the interior of the through hole 58. The second portion 62 is bonded to the inner circumferential surface of the through hole 58. The second portion 62, for example, seals the through hole 58.
[0059] like Figure 2 As shown, the wire harness 10, for example, has a first sliding limiting member 71 that restricts the sliding movement of the first path limiting member 40 relative to the outer member 30 in the longitudinal direction. Additionally, the wire harness 10, for example, has a second sliding limiting member 72 that restricts the sliding movement of the second path limiting member 50 relative to the outer member 30 in the longitudinal direction. The first sliding limiting member 71 and the second sliding limiting member 72 can be, for example, made of resin or metal, such as cable ties, fastening rings, or adhesive tape. In this embodiment, the first sliding limiting member 71 and the second sliding limiting member 72 are adhesive tape. The first sliding limiting member 71 is wound around the end of the first path limiting member 40 that is not connected to the second path limiting member 50 and the outer member 30. The second sliding limiting member 72 is wound around the end of the second path limiting member 50 that is not connected to the first path limiting member 40 and the outer member 30.
[0060] The effects of this implementation method will be explained. (1) The wire harness 10 includes a filler 60, which is filled between the wire harness body 11 and the covering portion 52 through the through hole 58. According to this structure, the wire harness body 11, which passes through the inside of the covering portion 52, is pressed against the covering portion 52 by the filler 60. This suppresses the shaking of the covering portion 52 and the wire harness body 11. Furthermore, in the above embodiment, the receiving portion 53 and the cover portion 54 are pushed apart by the pressure of the filler 60. This suppresses the shaking between the first connecting portion 55 of the receiving portion 53 and the groove 57 of the cover portion 54.
[0061] (2) The first portion 61 of the filler 60 enters the insertion port 40X. Furthermore, the first portion 61 is located between the outer peripheral surface of the outer member 30 and the inner peripheral surface of the covering portion 52. According to this structure, the outer member 30 and the first path limiting member 40 can be pressed against the covering portion 52 using the filler 60 filled between the outer member 30 and the covering portion 52. Additionally, because the filler 60 enters the insertion port 40X of the first path limiting member 40, the circumferential rotation of the first path limiting member 40 can be suppressed using the filler 60. Furthermore, because the filler 60 enters the insertion port 40X of the first path limiting member 40, compared to a structure where the filler 60 contacts the outer peripheral surface of the first path limiting member 40, the covering portion 52 can be radially miniaturized.
[0062] (3) The through hole 58 is opposite the insertion port 40X in the radial direction of the covering portion 52. According to this structure, the filler 60 can be properly inserted into the insertion port 40X. (4) The second part 62, which is part of the filler 60, enters the interior of the through hole 58. According to this structure, the through hole 58 can be sealed with the filler 60.
[0063] (5) The second path limiting member 50 includes: a main body portion 51 that limits the path of the outer component 30; and a receiving portion 53 disposed at the end of the main body portion 51 in the longitudinal direction of the wire harness body 11. Furthermore, the second path limiting member 50 includes a cover portion 54, which, together with the receiving portion 53, covers the entire circumference of the first path limiting member 40. The receiving portion 53 and the cover portion 54 constitute a covering portion 52. According to this structure, the receiving portion 53 and the cover portion 54 can be used to form a covering portion 52 that covers the outer circumference of the first path limiting member 40.
[0064] (6) A through hole 58 is provided in the cover portion 54. According to this structure, filler 60 can be filled through the through hole 58 provided in the cover portion 54. (7) The filler 60 is made of resin material. According to this structure, the wire harness body 11 can be properly pressed onto the covering part 52 using the filler 60 made of resin material.
[0065] (8) The mounting member installed on the first path limiting member 40 is a second path limiting member 50 installed on the outer periphery of the outer member 30 and limiting the path of the outer member 30. Furthermore, a covering portion 52 is installed at the longitudinal end of the second path limiting member 50, covering the outer periphery of the longitudinal end of the first path limiting member 40. Therefore, the first path limiting member 40 and the second path limiting member 50 are connected in the longitudinal direction. Thus, the path of the outer member 30 is continuously limited by the first path limiting member 40 and the second path limiting member 50.
[0066] (9) The first path limiting member 40 limits the path of the straight portion 11A, which is a straight section in the path of the wire harness body 11. The second path limiting member 50 limits the path of the bent portion 11B, which is a bent section in the path of the wire harness body 11. According to this structure, the paths of the straight portion 11A and the bent portion 11B of the wire harness body 11 can be continuously prevented from deviating from the desired paths.
[0067] This implementation can be carried out with the following modifications. This implementation and the following modifications can be combined with each other within the scope of technical inconsistency. • In the covering portion 52 of the above embodiment, a through hole 58 for filling the filler 60 is provided in the cover portion 54, but it is not particularly limited to this.
[0068] For example, such as Figure 5 As shown, a through hole 81 for filling the filler 60 can also be provided in the receiving portion 53 of the covering portion 52. As shown in the figure, the through hole 81 is a hole that extends from the outer peripheral side to the inner peripheral side of the covering portion 52. The through hole 81 extends through the receiving portion 53, for example, along the radial direction of the covering portion 52. The through hole 81 is provided in the first path limiting member 40 at a position corresponding to the outer peripheral surface of the connecting portion 43. That is, the through hole 81 faces the outer peripheral surface of the connecting portion 43 in the radial direction of the covering portion 52. The filler 60 filled from the through hole 81 is located between the outer peripheral surface of the connecting portion 43 and the inner peripheral surface of the receiving portion 53. With this structure, the first path limiting member 40 can also be pressed against the covering portion 52 using the filler 60 filled between the connecting portion 43 and the covering portion 52 of the first path limiting member 40.
[0069] ■ In the above embodiment, the covering part 52 is designed to have a receiving part 53 and a cover part 54, but it is not limited to this. For example, the covering part 52 may be modified to be a cylindrical structure that cannot be disassembled or deformed.
[0070] Furthermore, in the above embodiment, the cover portion 54 is separate from the receiving portion 53, but this is not particularly limiting; the cover portion 54 and the receiving portion 53 may also be formed as one piece. For example, in Figure 6 In the structure shown, the cover portion 54 is integrally formed with the receiving portion 53 via a thin-walled hinge portion 91. That is, the receiving portion 53 and the cover portion 54 are connected by the hinge portion 91. The hinge portion 91 connects one circumferential end of the receiving portion 53 and one circumferential end of the cover portion 54. A locking portion 92 is provided at the other circumferential end of the receiving portion 53. A claw portion 93 is provided at the other circumferential end of the cover portion 54.
[0071] The cover 54 can be in the open position with the hinge 91 as the axis. Figure 6 The cover 54 rotates between the closed positions shown. With the cover 54 in the closed position, the claw 93 hooks onto the locking part 92. Thus, the cover 54 remains in the closed position. In this way, the receiving part 53 and the cover 54 are connected to each other. With the receiving part 53 and the cover 54 connected, the covering part 52 forms an annulus that surrounds the outer periphery of the outer member 30 and the end of the first path limiting member 40. Even if the covering part 52 is as shown... Figure 6 The structure shown can also suppress the shaking of the covering part 52 and the wire harness body 11 by the pressure of the filler 60.
[0072] ■ In the covering portion 52 of the above embodiment, the concave-convex relationship of the first connecting portion 55 and the second connecting portion 56 may also be reversed. That is, it may also be configured such that the second connecting portion 56 is inserted into the groove provided in the first connecting portion 55.
[0073] ■ The shape of the through hole 58 viewed from the through direction is not limited to the above embodiment, and may be changed to a circle, a polygon, etc. ■The material of the filler 60 is not limited to the above embodiment. It can be appropriately changed as long as it is a material that is appropriately elastic between the wire harness body 11 and the covering part 52.
[0074] In the covering portion 52 of the above embodiment, multiple through holes 58 and filler 60 are provided in the circumferential direction. For example, through holes 58 may also be provided in the receiving portion 53, and filler 60 may be filled from the through holes 58 of the cover portion 54 and the receiving portion 53 respectively.
[0075] The second path limiting member 50 in the above embodiment is formed to limit the path of the bent portion 11B of the wire harness body 11, but it is not limited thereto. For example, the second path limiting member 50 may be changed to a shape that limits the path of the straight portion 11A of the wire harness body 11. In this case, the bent shape of the main body portion 51 may be changed to a shape that extends in a straight line.
[0076] ■In the above embodiment, the mounting member installed on the first path limiting member 40 is specifically embodied as the second path limiting member 50, but it is not limited thereto. For example, the mounting member may also be embodied as a vehicle mounting member for mounting the first path limiting member 40 on the vehicle V.
[0077] ■The structure of the first path limiting member 40 in the above embodiment can be appropriately modified. For example, as long as the first path limiting member 40 has an insertion port 40X and a structure that can be installed on the outer periphery of the outer member 30, other structures are not particularly limited.
[0078] ■ Alternatively, the protrusion 45 of the above embodiment can be provided at a position in the circumferential direction of the first path limiting member 40 that is further away from the insertion port 40X than the top end of the first end 41. ■ Alternatively, the protrusion 46 of the above embodiment can be provided at a position in the circumferential direction of the first path limiting member 40 that is further away from the insertion port 40X than the top end of the second end 42.
[0079] ■ Alternatively, the protrusions 45 and 46 of the above embodiment may be partially provided in the length direction of the first path limiting member 40. ■ At least one of the protrusions 45 and 46 in the above embodiments may also be omitted.
[0080] ■The shape of the connecting portion 43 in the first path limiting member 40 of the above embodiment is not limited to an arc shape, and can be changed to, for example, an elliptical arc shape, a U-shaped shape, etc. ■ In the above embodiment, the first path limiting member 40 and the second path limiting member 50 are harder than the outer member 30, but they are not limited to this; they may also be of equal or less hardness to the outer member 30. That is, the first path limiting member 40 and the second path limiting member 50 only need to function in a way that makes the wire harness body 11 less prone to bending than the wire harness body 11 without the first path limiting member 40 and the second path limiting member 50 installed.
[0081] ■The external component 30 in the above embodiment may, for example, be an external component in which a metal layer containing a metal material is provided on the outer surface of a resin corrugated pipe. ■The external component 30 of the above embodiment is not limited to a bellows, and may also be an external component without a large diameter portion 31 and a small diameter portion 32.
[0082] ■The outer component 30 in the above embodiment may also be an outer component having a slit extending in the length direction of the outer component 30. ■ In the above embodiment, the wire 21 is a high-voltage wire, but it is not limited to this. For example, the wire 21 can also be a low-voltage wire.
[0083] In the wire component 20 of the above embodiment, the electromagnetic shielding component is specifically embodied as a braided component 25, but it is not limited thereto. For example, the electromagnetic shielding component in the wire component 20 may also be embodied as a metal foil.
[0084] ■ The braided component 25 in the wire component 20 of the above embodiment may also be omitted. ■ In the above embodiment, two wires 21 constituting the wire member 20 are provided, but it is not limited to this. The number of wires 21 can be one or more.
[0085] ■ The configuration relationship between the inverter M1 and the high-voltage battery M2 in vehicle V is not limited to the above implementation method, and can be appropriately changed according to the vehicle structure. ■In the above embodiment, the multiple vehicle-mounted devices electrically connected to the wiring harness 10 are specifically embodied as an inverter M1 and a high-voltage battery M2, but are not limited thereto. The multiple vehicle-mounted devices electrically connected to the wiring harness 10 are not particularly limited as long as they are electrical devices mounted on the vehicle V.
