[0008] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. The wiring harness of the present invention, [1] Installed on an installation object, the installation object includes a fixed portion and an opening and closing body that opens and closes between a fully open position and a fully closed position relative to the fixed portion, the wiring harness includes a wire sheath and a wire component that passes through the wire sheath, the wire sheath is arranged between the fixed portion and the opening and closing body, the wire sheath has a fixed side end fixed to the fixed portion and a movable side end fixed to the opening and closing body, the wire component passes through the inside of the wire sheath and is wired throughout the fixed portion and the opening and closing body, and when the torsion angle of the wire component when the opening and closing body is in the fully open position is set to a positive value, the wire sheath holds the wire component in such a manner that the torsion angle is 0 degrees when the opening and closing body is in an intermediate position between the fully open position and the fully closed position, and in such a manner that the torsion angle is a negative value when the opening and closing body is in the fully closed position.

[0009] According to this structure, when the opening and closing body is in the middle position, the wire component is in a neutral state without twisting. In addition, the wire component can be configured to twist in the opposite direction in the fully open position and the fully closed position. Therefore, compared with the case where the wire component is set to be in a neutral state when the opening and closing body is in the fully open position or the fully closed position, the twisting amount of the wire component accompanying the opening and closing of the opening and closing body can be suppressed to be smaller. As a result, damage to the wire component caused by the twisting accompanying the opening and closing of the opening and closing body can be suppressed.

[0010] [2] In the above [1], the absolute value of the torsion angle when the opening and closing body is in the fully open position may be equal to the absolute value of the torsion angle when the opening and closing body is in the fully closed position.

[0011] According to this structure, the twisting amount of the electric wire member can be made equal in the fully open position and the fully closed position. Therefore, the twisting amount of the electric wire member accompanying the opening and closing of the opening and closing body can be suppressed to a minimum.

[0012] [3] In the above [1] or [2], the intermediate position may be a position located in the middle between the fully open position and the fully closed position. According to this structure, the twisting amount of the electric wire member can be made equal in the fully open position and the fully closed position. Therefore, the twisting amount of the electric wire member accompanying the opening and closing of the opening and closing body can be suppressed to a minimum.

[0013] [4] In any one of the above [1] to [3], it may be that when a straight line connecting the center of the movable side end portion and the center of the fixed side end portion when the opening and closing body is in the fully open position is set as a first imaginary straight line, a straight line connecting the center of the movable side end portion and the center of the fixed side end portion when the opening and closing body is in the fully closed position is set as a second imaginary straight line, and a straight line connecting the center of the movable side end portion and the center of the fixed side end portion when the opening and closing body is in the middle position is set as a third imaginary straight line, the third imaginary straight line is set at a position that bisects the angle formed by the first imaginary straight line and the second imaginary straight line.

[0014] According to this structure, the twisting amount of the electric wire member can be made equal in the fully open position and the fully closed position. Therefore, the twisting amount of the electric wire member accompanying the opening and closing of the opening and closing body can be suppressed to a minimum.

[0015] [5] In any one of the above [1] to [4], the electric wire member may include a braided member. According to this configuration, the electric wire member includes the braided member that is easily damaged by twisting. Therefore, the damage suppression effect produced by suppressing the twisting amount of the electric wire member to be small can be more significantly obtained.

[0016] [Details of Embodiments of the Invention] A specific example of the wiring harness of the present invention is described below with reference to the accompanying drawings. In each of the drawings, for the sake of convenience of description, a part of the structure is sometimes enlarged or simplified. In addition, the size ratios of the various parts are sometimes different in each of the drawings. In addition, the "cylindrical" used in the description of this specification includes not only a shape in which a peripheral wall is continuously formed throughout the entire circumference, but also a shape in which a plurality of parts are combined to form a cylindrical shape, a shape such as a C-shape having a notch in a part of the circumference, and the like. In addition, the "cylindrical" shape includes a circle, an ellipse, and a polygon with a sharp corner or a rounded corner.

[0017] like Figure 1 As shown, the wire harness 10 of the present embodiment is installed on an installation object 11. The installation object 11 includes a fixing portion 12 and an opening and closing body 13 supported by the fixing portion 12. The opening and closing body 13 is configured to be openable and closable between a fully open position Po and a fully closed position Pc relative to the fixing portion 12. The installation object 11 is, for example, a vehicle. The fixing portion 12 is, for example, a vehicle body. The opening and closing body 13 is, for example, an opening and closing body of a rear door, a side door, a sliding door, a sunroof device, a rearview mirror, an interior mirror, etc. in the vehicle.

[0018] The opening and closing body 13 is connected to the fixed portion 12, for example, via a hinge shaft 14. The opening and closing body 13 is configured to be rotatable between a fully open position Po and a fully closed position Pc with the hinge shaft 14 as a rotation axis.

[0019] (Structure of the wiring harness 10) The wire harness 10 includes a cable sheath 20 and an electric wire member 30. The cable sheath 20 is formed of a flexible material. As a material forming the cable sheath 20, for example, rubber, elastomer, etc. can be used.

[0020] The wire sheath 20 is provided between the fixing portion 12 and the opening and closing body 13. In addition, the wire sheath 20 is provided, for example, near the hinge shaft 14. The wire sheath 20 is cylindrical as a whole. The wire member 30 passes through the wire sheath 20. The wire member 30 passes through the inside of the wire sheath 20 and is wired throughout the fixing portion 12 and the opening and closing body 13. One end portion of the wire member 30 is connected to a device (not shown) provided on the opening and closing body 13.

[0021] like Figure 5 As shown, the wire member 30 is, for example, an LVDS (Low Voltage Differential Signaling) cable having a wire 31 and a braided member 32 covering the outer periphery of the wire 31. The wire 31 is a single wire or a bundle of multiple wires having a core wire and an insulating coating. The braided member 32 is formed by braiding multiple metal wires, for example. The braided member 32 magnetically shields the wire 31.

[0022] (Structure of the cable protection cover 20) like Figure 2 and Figure 3 As shown in the figure, the cable sheath 20 has a fixed side end 21, a movable side end 22, and an intermediate portion 23. The fixed side end 21 is provided at one end in the length direction of the cable sheath 20. The movable side end 22 is provided at the other end in the length direction of the cable sheath 20. The intermediate portion 23 is a portion connecting the fixed side end 21 and the movable side end 22. The fixed side end 21 and the movable side end 22 each extend in a flange shape in a radial direction relative to the intermediate portion 23, for example. The wire member 30 penetrates the fixed side end 21, the intermediate portion 23, and the movable side end 22 of the cable sheath 20.

[0023] like Figure 3 As shown, the cable cover 20 has a fixing piece 24 for fixing the electric wire member 30. The fixing piece 24 is provided, for example, at the fixing side end portion 21. The electric wire member 30 is fixed to the fixing piece 24 by an adhesive tape 25, for example.

[0024] The middle portion 23 has a corrugated portion 26 in at least a portion in the longitudinal direction. The corrugated portion 26 is formed into a corrugated shape with a diameter that changes in size in the longitudinal direction. That is, the corrugated portion 26 has a structure in which a large diameter portion 26a and a small diameter portion 26b are alternately connected and arranged along the longitudinal direction. Figure 4 In the figure, for convenience of description, illustration of the detailed shape of the bellows portion 26 is omitted.

[0025] like Figure 4 As shown, the fixed side end portion 21 is fixed to the mounting surface 12a of the fixed portion 12. The movable side end portion 22 is fixed to the mounting surface 13a of the opening and closing body 13. like Figure 3 As shown, the fixed side end portion 21 has a lip portion 21a that is in close contact with the mounting surface 12a. The lip portion 21a is annular. The lip portion 21a is in close contact with the mounting surface 12a at a position surrounding a through hole (not shown) formed on the mounting surface 12a. Thus, the lip portion 21a seals the through hole. In addition, the center C1 of the fixed side end portion 21 described later coincides with the center of the annular lip portion 21a. The wire component 30 enters the interior of the fixed portion 12 from the through hole of the mounting surface 12a.

[0026] The movable side end portion 22 has a lip portion 22a that is in close contact with the mounting surface 13a. The lip portion 22a is annular. The lip portion 22a is in close contact with the mounting surface 13a at a position that surrounds a through hole (not shown) formed on the mounting surface 13a. Thus, the lip portion 22a seals the through hole. In addition, the center C2 of the movable side end portion 22 described later coincides with the center of the annular lip portion 22a. The wire component 30 enters the interior of the opening and closing body 13 from the through hole of the mounting surface 13a.

[0027] (Regarding the twisting accompanying the opening and closing of the opening and closing body 13) like Figure 4 As shown, the mounting surface 13a of the opening and closing body 13 and the movable side end 22 of the wire sheath 20 are displaced along with the opening and closing of the opening and closing body 13. And, due to the displacement of the movable side end 22 relative to the fixed side end 21 that does not displace when the opening and closing body 13 is opened and closed, the middle part 23 of the wire sheath 20 and the wire member 30 in the wire sheath 20 are twisted. "Twist" of the wire sheath 20 and the wire member 30 refers to deformation when rotating in a plane perpendicular to the longitudinal direction.

[0028] like Figure 3 As shown in FIG. 1 , in the electric wire member 30, the portion located inside the fixed side end portion 21 of the wire sheath 20 is defined as the first portion 30a, and the portion located inside the movable side end portion 22 is defined as the second portion 30b. In the following description, the torsion angle θ of the electric wire member 30 refers to the torsion angle of the second portion 30b relative to the first portion 30a.

[0029] like Figure 5As shown, when the opening and closing body 13 is located at the intermediate position Pm between the fully open position Po and the fully closed position Pc, the torsion angle θ of the wire member 30 is 0°. That is, at the intermediate position Pm, the wire member 30 is in a state where no torsion occurs. Furthermore, when the opening and closing body 13 is located at the fully open position Po, the torsion angle θ is a positive value, and when the opening and closing body 13 is located at the fully closed position Pc, the torsion angle θ is a negative value. That is, the second portion 30b of the wire member 30 is twisted in opposite directions at the fully open position Po and the fully closed position Pc.

[0030] like Figure 4 As shown, the center C2 of the movable side end 22 when the opening and closing body 13 is located at the fully open position Po is set as the opening center C2a. In addition, the center C2 of the movable side end 22 when the opening and closing body 13 is located at the fully closed position Pc is set as the closing center C2b. In addition, the center C2 of the movable side end 22 when the opening and closing body 13 is located at the intermediate position Pm is set as the intermediate center C2c. In addition, the straight line connecting the center C1 of the fixed side end 21 and the opening center C2a of the movable side end 22 is set as the first imaginary straight line L1. And, the straight line connecting the center C1 of the fixed side end 21 and the closing center C2b of the movable side end 22 is set as the second imaginary straight line L2. The first imaginary straight line L1 and the second imaginary straight line L2 are set to be equal in length to each other. That is, a triangle with the center C1 of the fixed side end 21, the opening center C2a and the closing center C2b as vertices forms an isosceles triangle.

[0031] Here, for example, the middle position Pm of the opening and closing body 13 is a position located in the middle of the fully open position Po and the fully closed position Pc. That is, in the opening and closing body 13, the amount of movement from the middle position Pm to the fully open position Po is equal to the amount of movement from the middle position Pm to the fully closed position Pc. Therefore, when the straight line connecting the center C1 of the fixed side end 21 and the center C2c of the middle of the movable side end 22 is set as the third imaginary straight line L3, the third imaginary straight line L3 becomes a straight line that bisects the angle θ1 formed by the first imaginary straight line L1 and the second imaginary straight line L2. As a result, the absolute value |α| of the torsion angle θ when the opening and closing body 13 is in the fully open position Po is equal to the absolute value |α| of the torsion angle θ when the opening and closing body 13 is in the fully closed position Pc. That is, the wire component 30 is twisted by the same amount at the fully open position Po and the fully closed position Pc.

[0032] like Figure 3As shown in FIG. 1 , the central axis L4 of the fixed-side end portion 21 of the grommet 20 is orthogonal to the support surface 21b of the fixed-side end portion 21 and passes through the center C1 of the fixed-side end portion 21. Furthermore, the angle formed by the axis CL along the length direction of the intermediate portion 23 and the central axis L4 is set as the first turret angle θ2. In addition, the central axis L5 of the movable-side end portion 22 is orthogonal to the support surface 22b of the movable-side end portion 22 and passes through the center C2 of the movable-side end portion 22. Furthermore, the angle formed by the axis CL of the intermediate portion 23 and the central axis L5 is set as the second turret angle θ3.

[0033] in addition, Figure 2 The rotation angle θ4 of the fixed end portion 21 is an angle of the fixed end portion 21 relative to the axis CL. The rotation angle θ4 is an angle in the rotation direction about the central axis L4 of the fixed end portion 21. The movable end portion 22 also has the same rotation angle as the rotation angle θ4.

[0034] The first turret angle θ2 of the fixed side end portion 21, the rotation angle θ4 of the fixed side end portion 21, the second turret angle θ3 of the movable side end portion 22, and the rotation angle of the movable side end portion 22 are set so that the middle portion 23 does not interfere with the fixed portion 12 and the opening and closing body 13 in the assembled state relative to the installation object 11. In addition, the first turret angle θ2 of the fixed side end portion 21, the rotation angle θ4 of the fixed side end portion 21, the second turret angle θ3 of the movable side end portion 22, and the rotation angle of the movable side end portion 22 are set so that when the opening and closing body 13 is opened and closed, the middle portion 23 interferes with the electric wire member 30, and stress does not concentrate locally on the electric wire member 30.

[0035] The effects of this embodiment will be described. (1) The wire sheath 20 holds the wire member 30 in such a manner that the torsion angle θ is 0 degrees when the opening and closing body 13 is located at the intermediate position Pm between the fully open position Po and the fully closed position Pc. According to this structure, when the opening and closing body 13 is located at the intermediate position Pm, the wire member 30 is in a neutral state without torsion. In addition, the wire member 30 can be configured to be twisted in opposite directions at the fully open position Po and the fully closed position Pc. Therefore, compared with the case where the wire member 30 is set to be in a neutral state when the opening and closing body 13 is located at the fully open position Po or the fully closed position Pc, the torsion amount of the wire member 30 accompanying the opening and closing of the opening and closing body 13 can be suppressed to a smaller value. As a result, damage to the wire member 30 caused by the torsion generated by the opening and closing of the opening and closing body 13 can be suppressed.

[0036] (2) The absolute value of the torsion angle θ when the opening and closing body 13 is in the fully open position Po is equal to the absolute value of the torsion angle θ when the opening and closing body 13 is in the fully closed position Pc. According to this structure, the torsion amount of the wire member 30 can be equal in the fully open position Po and the fully closed position Pc. Therefore, the torsion amount of the wire member 30 accompanying the opening and closing of the opening and closing body 13 can be suppressed to a minimum.

[0037] (3) The intermediate position Pm is a position located in the middle between the fully open position Po and the fully closed position Pc. According to this structure, the twisting amount of the wire member 30 can be equal in the fully open position Po and the fully closed position Pc. Therefore, the twisting amount of the wire member 30 accompanying the opening and closing of the opening and closing body 13 can be suppressed to a minimum.

[0038] (4) A straight line connecting the center C2 of the movable side end 22 and the center C1 of the fixed side end 21 when the opening and closing body 13 is in the fully open position Po is set as the first imaginary straight line L1. In addition, a straight line connecting the center C2 of the movable side end 22 and the center C1 of the fixed side end 21 when the opening and closing body 13 is in the fully closed position Pc is set as the second imaginary straight line L2. In addition, a straight line connecting the center C2 of the movable side end 22 and the center C1 of the fixed side end 21 when the opening and closing body 13 is in the middle position Pm is set as the third imaginary straight line L3. The third imaginary straight line L3 is set at a position that divides the angle θ1 formed by the first imaginary straight line L1 and the second imaginary straight line L2 into two equal parts. According to this structure, the torsion amount of the wire component 30 can be made equal at the fully open position Po and the fully closed position Pc. Therefore, the torsion amount of the wire component 30 accompanying the opening and closing of the opening and closing body 13 can be suppressed to a minimum.

[0039] (5) The wire component 30 includes a braided component 32 that is easily damaged by twisting. Therefore, the damage suppression effect produced by suppressing the twisting amount of the wire component 30 to be small can be more significantly obtained. In addition, the wire component 30 includes a braided wire included in the LVDS cable of the wire 31. This braided wire is also easily damaged by twisting like the braided component 32, so the damage suppression effect can be more significantly obtained.

[0040] (Variation Example) This embodiment can be implemented as the following modifications. This embodiment and the following modifications can be implemented in combination with each other within the range that there is no technical contradiction.

[0041] The third virtual straight line L3 may be set at a position that does not bisect the angle θ1 formed by the first virtual straight line L1 and the second virtual straight line L2. The intermediate position Pm may not be located at the center between the fully open position Po and the fully closed position Pc.

[0042] The absolute value of the torsion angle θ when the opening and closing body 13 is in the fully open position Po and the absolute value of the torsion angle θ when the opening and closing body 13 is in the fully closed position Pc may not be equal. In addition, the smaller the difference between the absolute value of the torsion angle θ when the opening and closing body 13 is in the fully open position Po and the absolute value of the torsion angle θ when the opening and closing body 13 is in the fully closed position Pc, the smaller the torsion amount of the wire member 30 accompanying the opening and closing of the opening and closing body 13.

[0043] The first imaginary straight line L1 and the second imaginary straight line L2 may be set to different lengths. In addition, the smaller the difference between the length of the first imaginary straight line L1 and the length of the second imaginary straight line L2, the smaller the bending amount of the intermediate portion 23 and the wire member 30 accompanying the opening and closing of the opening and closing body 13.

[0044] The electric wire member 30 may be fixed to the fixing piece 24 using, for example, a binding band. The fixing piece 24 may be provided only at the movable-side end portion 22 or may be provided at both the fixed-side end portion 21 and the movable-side end portion 22 .

[0045] The electric wire member 30 may be a structure including a plurality of electric wires 31 or a structure including the electric wire 31 and one or more electric wires independent therefrom. The wire component 30 is not limited to an LVDS cable having the wire 31 and the braided component 32. For example, the core wire of the wire 31 may be formed of a braided component formed by braiding a plurality of metal wires. In this case, the core wire of the wire 31 is formed of a braided component that is easily damaged by twisting, so the damage suppression effect generated by suppressing the twisting amount of the wire component 30 to a small value can be more significantly obtained.

[0046] ·like Figure 1 , 4 As shown, the hinge shaft 14 (rotation axis) can be located between the movable side end 22 of the grommet 20 and the fixed side end 21 of the grommet 20 in the fully opened position Po, or can be formed to extend in the same direction as the direction in which the mounting surface 12a of the fixing portion 12 extends.

[0047] The movable-side end portion 22 of the grommet 20 may be provided on the end portion side in the axial direction of the hinge shaft 14 relative to the fixed-side end portion 21 of the grommet 20 . The open center C2a, the closed center C2b, and the intermediate center C2c of the movable side end portion 22 of the grommet 20 may coincide with the center of the through hole formed on the mounting surface 13a of the opening and closing body 13 to fix the movable side end portion 22, and the center C1 of the fixed side end portion 21 of the grommet 20 may coincide with the center of the through hole formed on the mounting surface 12a of the fixing portion 12 to fix the fixed side end portion 21. The open center C2a, the closed center C2b, and the intermediate center C2c may be located on different planes.

[0048] ·like Figure 3 , 4 As shown, the first portion 30a of the wire component 30 is fixed to the fixed side end portion 21 of the wire cover 20, and when the opening and closing body 13 is located in the fully open position Po or the fully closed position Pc, the second portion 30b of the wire component 30 can be twisted together with the movable side end portion 22 of the wire cover 20 relative to the first portion 30a of the wire component 30 with the hinge axis 14 as the center.

[0049] [Supplementary Note 1] According to some embodiments of the present invention, the wiring harness 10 may also include a slender cylindrical wire sheath 20 and a wire member 30 passing through the slender cylindrical wire sheath 20, wherein the wire sheath 20 is elastically connected to the opening and closing body 13 that can be moved to the fully open position Po and the fully closed position Pc, for example Figure 5 As shown, When the opening and closing body 13 is located at the fully closed position Pc, the wire member 30 held by the wire sheath 20 may be in the first twisted state. When the opening and closing body 13 is located at the fully opened position Po, the wire member 30 held by the wire cover 20 may be in a second twisted state different from the first twisted state. When the opening and closing body 13 is located at the intermediate position Pm, the electric wire member 30 held by the cable cover 20 may be in a non-twisted state different from the first twisted state and the second twisted state.

[0050] [Supplementary Note 2] In some embodiments of the present invention, the electric wire component 30 may also include an LVDS line including a metal braided component. Note 3] For example Figure 3 As shown, in several embodiments of the present invention, the wire component 30 retained in the wire sheath 20 may also include a first length position and a second length position, the first length position can be a first portion 30a corresponding to the fixed side end portion 21 of the wire sheath 20, and the second length position can be a second portion 30b corresponding to the movable side end portion 22 of the wire sheath 20.

[0051] [Note 4] For example Figure 5As shown, in several embodiments of the present invention, when the wire member 30 is cross-sectionally viewed, When the opening and closing body 13 is in the fully closed position Pc and the wire component 30 held in the wire sheath 20 is in the first twisted state, the second length position of the wire component 30 can also be twisted clockwise (CW) or counterclockwise (CCW) relative to the first length position of the wire component 30. When the opening and closing body 13 is in the fully opened position Po and the wire component 30 held in the wire sheath 20 is in the second twisted state, the second length position of the wire component 30 may be twisted in the other direction of clockwise and counterclockwise relative to the first length position of the wire component 30. When the opening and closing body 13 is located at the middle position Pm and the wire component 30 held in the wire sheath 20 is in the non-twisted state, the second length position of the wire component 30 may not be twisted clockwise or counterclockwise relative to the first length position of the wire component 30.
