DETAILED DESCRIPTION OF THE INVENTION

[0008] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. [1] A wire harness according to the present disclosure includes a plurality of electric wire members each including a first shielded electric wire having a cylindrical first individual shielding member and a conductive member electrically connected to the first shielded electric wire; a cylindrical member surrounding an outer periphery of the conductive member and having electrical conductivity; and a cylindrical first shielding member surrounding an outer periphery of a portion of the plurality of electric wire members that is exposed from the first individual shielding member and the cylindrical member and having electrical conductivity, wherein each of the plurality of first shielded electric wires included in the plurality of electric wire members includes a conductive first core wire and the first individual shielding member. The cable has a first insulating coating that surrounds the outer periphery of the core wire and has insulating properties, a first individual shielding member that surrounds the outer periphery of the first insulating coating and is conductive, and a first sheath that surrounds the outer periphery of the first individual shielding member and has insulating properties, wherein an end of the first individual shielding member has a first exposed portion that is exposed from the end of the first sheath, and the first shielding member is electrically connected to the first individual shielding member while in contact with the multiple first exposed portions of the multiple electric wire members and is also electrically connected to the tubular member.

[0009] According to this configuration, the first shielding member is electrically connected to the first individual shielding member while in contact with the multiple first exposed portions, and is also electrically connected to the tubular member. This allows the first individual shielding member and the tubular member to be electrically connected via the first shielding member. Therefore, the electric wire members can be suitably electromagnetically shielded by the first shielding member, the first individual shielding member, and the tubular member. Here, the first shielding member is provided to surround the outer peripheries of the portions of the multiple electric wire members that are exposed from the first individual shielding member and the tubular member. Therefore, even if the electric wire members have portions that are exposed from the first individual shielding member and the tubular member, the exposed portions can be surrounded by a first shielding member that is separate from the first individual shielding member and the tubular member. This allows the electric wire members in the exposed portions to be suitably electromagnetically shielded by the first shielding member. Therefore, even if the electric wire members have portions that are exposed from the first individual shielding member and the tubular member, a decrease in electromagnetic shielding performance in the exposed portions can be suitably suppressed. As a result, it is possible to suitably prevent electromagnetic waves (electromagnetic noise) generated in the exposed portion from being radiated to the outside of the wire harness.

[0010] [2] Preferably, the first shielding member is arranged to span between the multiple first exposed portions and the tubular member in the longitudinal direction of the electric wire member, a first axial end of the first shielding member collectively surrounding the outer peripheries of the multiple first exposed portions and being fixed to the outer periphery of the multiple first shielded electric wires while being in contact with the multiple first exposed portions, and a second axial end of the first shielding member collectively surrounding the outer periphery of the tubular member over the entire circumferential direction and being fixed to the outer periphery of the tubular member while being in contact with the outer periphery of the tubular member. According to this configuration, the first shielding member is formed to span between the multiple first exposed portions and the tubular member. Furthermore, the first shielding member is formed to collectively surrounding the outer periphery of the multiple first exposed portions and being formed to surround the outer periphery of the tubular member over the entire circumferential direction. Therefore, the outer periphery of the multiple first shielded electric wires arranged between the first exposed portion and the tubular member can be surrounded by a single first shielding member, and the multiple first shielded electric wires can be electromagnetically shielded in an appropriate manner by the first shielding member.

[0011] [3] Preferably, each of the plurality of first exposed portions has a structure folded back toward the end of the first sheath and surrounds the outer periphery of the end of the first sheath. With this configuration, the first exposed portions and the first shielding member can be electrically connected when the first exposed portions folded back to surround the outer periphery of the end of the first sheath are in contact with each other.

[0012] [4] The cable further includes an underlay member provided between the outer periphery of the end of the first sheath and the first exposed portions, and a connecting member connecting the plurality of first exposed portions and the first shielding member. The underlay member is preferably a metal ring member attached to each of the plurality of first shielded electric wires, and the connecting member electrically connects the plurality of first exposed portions and the first shielding member with the plurality of first exposed portions and the first shielding member sandwiched between the underlay member and the connecting member. According to this configuration, the underlay member, which is a metal ring member, is interposed between the first sheath and the first exposed portions. The plurality of first exposed portions and the first shielding member are sandwiched between the underlay member and the connecting member. As a result, when the connecting member is tightened around the plurality of first exposed portions, the presence of the underlay member between the first exposed portions and the first sheath can suppress deformation of the shielded electric wire. As a result, the stability of the electrical connection between the first exposed portions and the first shielding member can be improved. Furthermore, since the underlay member is attached to each of the plurality of first shielded electric wires, deformation of each of the plurality of first shielded electric wires can be suitably suppressed.

[0013] [5] Preferably, the connection portion between the plurality of first exposed portions and the first shielding member has a structure in which the plurality of first exposed portions are bundled together so as to be in contact with one another and each of the plurality of first exposed portions is in contact with the first shielding member. With this configuration, each of the plurality of first exposed portions is in direct contact with the first shielding member, thereby improving the stability of the electrical connection between the plurality of first exposed portions and the first shielding member.

[0014] [6] Preferably, the plurality of first shielded electric wires are three or more first shielded electric wires, and the three or more first shielded electric wires are arranged along a first direction intersecting the longitudinal direction of the electric wire member and a second direction intersecting the longitudinal direction of the electric wire member and intersecting the first direction. According to this configuration, the three or more first shielded electric wires are arranged side by side along the first direction and the second direction. Therefore, compared to a case where, for example, three or more first shielded electric wires are arranged side by side only along the first direction, it is possible to preferably prevent the first shielded electric wires from becoming large in size in the first direction.

[0015] [7] The first individual shield member is preferably provided outside the tubular member in the longitudinal direction of the electric wire member. This configuration eliminates an overlapping area between the first individual shield member and the tubular member, i.e., an area that is excessively electromagnetically shielded by the two shield members, the first individual shield member and the tubular member. This prevents the first individual shield member from being formed longer than necessary, compared to, for example, a case where the first individual shield member is formed to extend into the tubular member, and reduces unnecessary portions of the first individual shield member.

[0016] [8] Preferably, the conductive member is a single-core wire made of a single conductor, the single-core wire being housed inside the tubular member, and the first core wire of the first shielded electric wire being electrically connected to the single-core wire inside the tubular member. According to this configuration, the single-core wire and the connection portion between the single-core wire and the first core wire are housed inside the tubular member. Therefore, the single-core wire and the electric wire member at the connection portion can be suitably electromagnetically shielded by the tubular member. Furthermore, the single-core wire and the connection portion can be suitably protected by the tubular member.

[0017] [9] Each of the plurality of electric wire members has one of the single core wires, the first shielded electric wire electrically connected to one end of the single core wire in the length direction, and a second shielded electric wire electrically connected to the other end of the single core wire in the length direction, and each of the plurality of second shielded electric wires of the plurality of electric wire members has a second core wire having conductivity, a second insulating coating that surrounds the outer periphery of the second core wire and has insulation, a second individual shield member that surrounds the outer periphery of the second insulating coating and has conductivity, and a second individual shield member that surrounds the outer periphery of the second individual shield member. Preferably, the cable further includes a conductive cylindrical second shielding member that surrounds the outer peripheries of the portions of the plurality of electric wire members that are exposed from the second individual shielding members and the tubular member, and an end of the second individual shielding member has second exposed portions that are exposed from the end of the second sheath, and the second shielding member is electrically connected to the second individual shielding members while contacting the second exposed portions of the plurality of electric wire members, and is also electrically connected to the tubular member. According to this configuration, the second shielding member is electrically connected to the second individual shielding member while contacting the second exposed portions, and is also electrically connected to the tubular member. This allows the second individual shielding member and the tubular member to be electrically connected via the second shielding member. Therefore, the electric wire members can be suitably electromagnetically shielded by the second shielding member, the second individual shielding member, and the tubular member. Here, the second shielding member is arranged to surround the outer peripheries of the portions of the plurality of electric wire members that are exposed from the second individual shielding members and the tubular member. Therefore, even if the electric wire member has a portion exposed from the second individual shield member and the tubular member, the exposed portion can be surrounded by a second shield member that is separate from the second individual shield member and the tubular member. This allows the electric wire member at the exposed portion to be suitably electromagnetically shielded by the second shield member. Therefore, even if the electric wire member has a portion exposed from the second individual shield member and the tubular member, it is possible to suitably prevent a decrease in electromagnetic shielding performance at the exposed portion.As a result, it is possible to suitably prevent electromagnetic waves generated in the exposed portion from being radiated to the outside of the wire harness.

[0018]

[10] Preferably, each of the plurality of electric wire members includes one of the single-core wires and two or more of the first shielded electric wires electrically connected to one end of the single-core wire in the longitudinal direction. According to this configuration, two or more first shielded electric wires are electrically connected to one end of the single-core wire. This makes it possible, for example, to distribute power supplied to the single-core wire to two or more first shielded electric wires.

[0019] [Details of the embodiments of the present disclosure] Specific examples of wire harnesses according to the present disclosure will be described below with reference to the drawings. For ease of explanation, some components may be exaggerated or simplified in the drawings. The dimensional ratios of the components may differ between the drawings. In this specification, "parallel" and "orthogonal" do not necessarily mean strictly parallel or orthogonal, but also include roughly parallel or orthogonal within the scope of the present embodiment's advantageous effects. In this specification, "opposite" refers to surfaces or components facing each other, and includes not only cases where the surfaces or components are completely opposite each other but also cases where the surfaces are partially opposite each other. In this specification, "opposite" refers to both cases where a separate component is interposed between the two components and cases where there is no interposition between the two components. In this specification, "cylindrical" refers not only to a component having a continuous peripheral wall formed around the entire circumference, but also to a component formed by combining multiple components and a component having a notch in the circumferential direction, such as a C-shape. The "cylindrical" shape includes a circle, an ellipse, and a polygon with pointed or rounded corners. It should be noted that the present invention is not limited to these examples, but is defined by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0020] (Overall configuration of the wire harness 10) The wire harness 10 shown in FIG. 1 is mounted on a vehicle V, such as a hybrid vehicle or an electric vehicle. The wire harness 10 electrically connects, for example, two or more in-vehicle devices. The in-vehicle devices are electrical devices mounted on the vehicle V. The wire harness 10 of this embodiment electrically connects a high-voltage battery M1 and multiple in-vehicle devices M2, M3. The wire harness 10 is formed in an elongated shape so as to extend, for example, in the fore-and-aft direction of the vehicle V.

[0021] The battery M1 is, for example, provided toward the rear of the vehicle V. An example of the in-vehicle device M2 is an inverter provided forward of the battery M1 on the vehicle V. The battery M1 is, for example, a high-voltage battery capable of supplying a voltage of 100 volts or more. The in-vehicle device M2 as an inverter is connected, for example, to a wheel drive motor (not shown) that serves as a power source for running the vehicle. The inverter generates AC power from DC power from the battery M1 and supplies the AC power to the motor. The in-vehicle device M3 is, for example, an electric device such as an air conditioner or a DC / DC converter. DC power is supplied to the in-vehicle device M3 from the battery M1. In this way, the wire harness 10 distributes and supplies DC power from the battery M1 to the multiple in-vehicle devices M2 and M3. The in-vehicle devices M2 and M3 are provided, for example, in a vehicle interior such as an engine compartment.

[0022] In this embodiment, for convenience, the side of the wire harness 10 that is closer to the battery M1 in the longitudinal direction is referred to as the rear, and the side of the wire harness 10 that is closer to the in-vehicle devices M2 and M3 in the longitudinal direction is referred to as the front. Also, the end of each member located on the battery M1 side is referred to as the rear end, and the end of each member located on the in-vehicle devices M2 and M3 side is referred to as the front end.

[0023] The wire harness 10 includes one or more electric wire members 20 that electrically connect the battery M1 and two in-vehicle devices M2 and M3, and an exterior member 70 that surrounds the outer periphery of the electric wire members 20. The wire harness 10 of this embodiment includes two electric wire members 20.

[0024] As shown in FIG. 2 , each electric wire member 20 has one single core wire 21. The single core wire 21 has a front end portion which is one end portion of the single core wire 21 in the length direction, and a rear end portion which is the other end portion of the single core wire 21 in the length direction. Each electric wire member 20 has two or more electric wires 31, 32 (two in this embodiment) connected to the front end portion of the single core wire 21, and one electric wire 41 connected to the rear end portion of the single core wire 21. Each electric wire member 20 has a first connection portion 51 at which the single core wire 21 and the plurality of electric wires 31, 32 are connected, a second connection portion 52 at which the single core wire 21 and the electric wire 41 are connected, and a covering member 60. Each electric wire member 20 is formed by electrically connecting different types of electric wires 31, 32, the single core wire 21, and the electric wire 41 in the length direction of the electric wire member 20. The exterior member 70 includes, for example, a cylindrical member 71 that surrounds the outer periphery of the single core wire 21, a waterproof member 81, and a waterproof member .

[0025] 1 , the wire harness 10 includes, for example, a connector C1 attached to the rear end of the electric wire 41, a connector C2 attached to the front end of the electric wire 31, and a connector C3 attached to the front end of the electric wire 32. The rear end of the electric wire 41 is electrically connected to the battery M1 via the connector C1, and the front end of the electric wire 41 is electrically connected to the rear end of the single-core wire 21. The front end of the electric wire 31 is electrically connected to the in-vehicle device M2 via the connector C2, and the rear end of the electric wire 31 is electrically connected to the front end of the single-core wire 21. As a result, the battery M1 and the in-vehicle device M2 are electrically connected via the connector C1, the electric wire 41, the single-core wire 21, the electric wire 31, and the connector C2. The front end of the electric wire 32 is electrically connected to the in-vehicle device M3 via the connector C3, and the rear end of the electric wire 32 is electrically connected to the front end of the single-core wire 21. As a result, the battery M1 and the in-vehicle device M3 are electrically connected via the connector C1, the electric wire 41, the single-core wire 21, the electric wire 32, and the connector C3.

[0026] In the wire harness 10, one electric wire 41 and a single-core wire 21 are branched into two or more electric wires 31, 32 at a longitudinal intermediate portion of the electric wire member 20. In the wire harness 10 of this embodiment, DC power supplied from a battery M1 is distributed to the plurality of electric wires 31, 32 and supplied to on-vehicle devices M2, M3 through the electric wires 31, 32. In the wire harness 10, for example, the single-core wire 21 and the electric wire 41 function as main electric wires, and the electric wires 31, 32 function as branch electric wires. The electric wires 31, 32, 41 are, for example, high-tension electric wires capable of handling high voltages and large currents.

[0027] (Configuration of single-core wire 21) As shown in Figs. 2 and 3, the single core wire 21 is provided in the middle portion of the electric wire member 20 in the longitudinal direction. The single core wire 21 is formed to have higher bending rigidity than, for example, the electric wire 41. The single core wire 21 is formed to have higher bending rigidity than, for example, each of the electric wires 31 and 32. The single core wire 21 has rigidity that allows it to maintain a shape along the routing path of the wire harness 10. For example, the single core wire 21 has rigidity that prevents it from being released from a straight or bent state due to vibrations of the vehicle V or the like when it is mounted on the vehicle V. The single core wire 21 can be made of, for example, a metal material such as a copper-based or aluminum-based material.

[0028] The single core wire 21 is made of a single conductor. For example, the single core wire 21 may be a columnar conductor made of a single columnar metal rod having a solid interior, or a tubular conductor having a hollow interior. The single core wire 21 of this embodiment is a flat columnar conductor made of a single metal rod having a solid interior in the shape of a rectangular column (for example, a rectangular parallelepiped). The single core wire 21 is formed in an elongated shape so as to extend in the fore-and-aft direction of the vehicle V.

[0029] As shown in FIG. 4 , the single core wire 21 of this embodiment is formed in a flat plate shape. The single core wire 21 is a flat plate-like member that extends in a lengthwise direction (axial direction) and a widthwise direction perpendicular to the lengthwise direction, and that has a predetermined thickness in a thicknesswise direction perpendicular to the lengthwise and widthwise directions. The cross-sectional shape of the single core wire 21 obtained by cutting the single core wire 21 along a plane perpendicular to the lengthwise direction of the single core wire 21, i.e., the transverse cross-sectional shape of the single core wire 21, is formed, for example, in a flat shape. In this specification, the term "flat shape" includes, for example, a rectangle and an oval. In addition, a "rectangle" in this specification refers to a shape having long sides and short sides and excludes a square. In addition, a "rectangle" in this specification also includes a shape with chamfered ridges or a shape with rounded ridges. Note that FIG. 4 illustrates only some of the components of the wire harness 10.

[0030] The single core wire 21 of this embodiment has a rectangular cross-sectional shape. For example, the cross-sectional shape of the single core wire 21 is the same rectangle over the entire length of the single core wire 21. The single core wire 21 has four end faces: a pair of long side faces 22 including the long sides of the rectangle, and a pair of short side faces 23 including the short sides of the rectangle. These pair of long side faces 22 and the pair of short side faces 23 are formed to extend over the entire length of the single core wire 21 in the length direction. Each long side face 22 has a larger surface area per unit length of the single core wire 21 than each short side face 23.

[0031] As shown in Fig. 3, the single core wires 21 of the multiple electric wire members 20 are arranged side by side in a direction intersecting the longitudinal direction of the electric wire members 20. The single core wires 21 are arranged side by side, for example, in a direction perpendicular to the longitudinal direction of the electric wire members 20 (the vertical direction in the figure). The single core wires 21 are arranged side by side, for example, with their long side surfaces 22 facing each other. The long side surface 22 of one single core wire 21 and the long side surface 22 of the other single core wire 21 are arranged so as to face each other. The long side surface 22 of one single core wire 21 and the long side surface 22 of the other single core wire 21 are arranged so as to extend parallel to each other, for example.

[0032] (Configuration of electric wires 31 and 32) 2 are more flexible than, for example, the single core wire 21. Each of the electric wires 31 and 32 are more flexible than, for example, the single core wire 21. The electric wires 31 and 32 have higher flexibility than, for example, the single core wire 21.

[0033] Each of the electric wires 31, 32 has a first core wire 33 made of a plurality of metal wires, and a first insulating coating 34 that surrounds the outer periphery of the first core wire 33 and has insulating properties. Each of the electric wires 31, 32 has, for example, a cylindrical first individual shield member 35 that surrounds the outer periphery of the first insulating coating 34 and has conductivity, and a first sheath 36 that surrounds the outer periphery of the first individual shield member 35 and has insulating properties. Each of the electric wires 31, 32 in this embodiment is a shielded electric wire that has an electromagnetic shield structure itself.

[0034] The first core wire 33 may be, for example, a stranded wire made by twisting together a plurality of metal wires or a braided wire made by weaving a plurality of metal wires into a cylindrical shape. The first core wire 33 of this embodiment is a stranded wire. The first core wire 33 may be made of, for example, a copper-based or aluminum-based metal material.

[0035] 5, the first insulating coating 34 covers, for example, the entire circumferential outer surface of the first core wire 33. The first insulating coating 34 is made of, for example, an insulating resin material.

[0036] The first individual shield member 35, for example, surrounds the outer peripheral surface of the first insulating coating 34 over the entire circumferential direction. The first individual shield member 35, for example, has flexibility. The first individual shield member 35 may be, for example, a braided wire in which a plurality of metal wires are woven into a tubular shape or a metal foil. The first individual shield member 35 of this embodiment is a braided wire. The first individual shield member 35 may be, for example, a copper-based or aluminum-based metal material.

[0037] The first sheath 36, for example, surrounds the entire circumferential outer periphery of the first individual shield member 35. The first sheath 36 is made of, for example, an insulating resin material.

[0038] The cross-sectional shape of each of the electric wires 31 and 32 is formed to be, for example, a circular shape. Note that the cross-sectional shape of each of the electric wires 31 and 32 is not limited to a circular shape and may be formed to be any shape such as a semicircular shape, a polygonal shape, a square shape, or a flat shape.

[0039] Each electric wire member 20 has two electric wires 31 and 32. Therefore, two electric wire members 20 have two electric wires 31 and two electric wires 32, a total of four electric wires 31 and 32. The four electric wires 31 and 32 are arranged side by side, for example, in a direction intersecting the longitudinal direction of the electric wire member 20. For example, the four electric wires 31 and 32 are arranged side by side along a first direction (vertical direction in the figure) intersecting the longitudinal direction of the electric wire member 20 and a second direction (horizontal direction in the figure) intersecting the longitudinal direction of the electric wire member 20 and intersecting the first direction. Specifically, two electric wires 31 are arranged side by side along the first direction. Two electric wires 32 are arranged side by side along the first direction. The electric wires 31 and 32 are arranged side by side along the second direction. In this way, the four electric wires 31 and 32 are arranged side by side vertically and horizontally in a cross section. The first direction in this embodiment coincides with the direction in which the single core wires 21 (see FIG. 3) are arranged.

[0040] As shown in FIG. 2 , the rear end of each first individual shield member 35 has, for example, a first exposed portion 37 exposed from the first sheath 36. At the rear end of each electric wire 31, 32, a predetermined length of the first sheath 36 is stripped from the end of the electric wire 31, 32, exposing the rear end of the first individual shield member 35 as the first exposed portion 37. For example, each first exposed portion 37 is folded back toward the rear end of the first sheath 36. For example, each first exposed portion 37 is folded back so as to cover the outer periphery of the rear end of the first sheath 36. Here, an underlying member 38 is attached to the outer periphery of the rear end of each first sheath 36. The underlying member 38 is attached individually to each of the plurality of electric wires 31 and each of the plurality of electric wires 32. The underlying member 38 is, for example, a metal ring member. The underlying member 38 is formed, for example, in a ring shape that surrounds the outer circumferential surface of the first sheath 36 over the entire circumferential direction. The first exposed portion 37 is, for example, folded back so as to cover the outer periphery of the underlying member 38. That is, the first exposed portion 37 surrounds the outer periphery of the underlying member 38. As shown in FIG. 5 , the first exposed portion 37 surrounds, for example, the outer circumferential surface of the underlying member 38 over the entire circumferential direction. The cross-sectional shape of the portion where the underlying member 38 is provided is formed into a structure in which the first insulating coating 34, the first individual shield member 35, the first sheath 36, the underlying member 38, and the first exposed portion 37 are layered in this order on the outer circumferential surface of the first core wire 33. Note that the underlying member 38 can be made of, for example, a copper-based or aluminum-based metal material.

[0041] Here, the two electric wire members 20 have four first exposed portions 37. The four first exposed portions 37 are arranged vertically and horizontally in a cross section, similar to the four electric wires 31, 32. The four first exposed portions 37 are arranged together so that the outer circumferential surfaces thereof contact each other.

[0042] 2 and 4 , at the rear end of each of the electric wires 31, 32 provided rearward of the first exposed portion 37, the rear end of the first core wire 33 is exposed from the first insulating coating 34. At the rear end of each of the electric wires 31, 32, a predetermined length of the first insulating coating 34 is stripped from the end of the electric wire 31, 32, exposing the rear end of the first core wire 33. Then, at each of the first connection portions 51, the rear end of the first core wire 33 of the electric wire 31 and the rear end of the first core wire 33 of the electric wire 32 are joined to the front end of the single core wire 21. For example, at each of the first connection portions 51, the first core wire 33 of the electric wire 31 and the first core wire 33 of the electric wire 32 are joined to one single core wire 21 while being overlapped individually in the radial direction, i.e., in a direction intersecting the length directions of the first core wire 33 and the single core wire 21. For example, in each first connection portion 51, two first core wires 33 are individually overlapped and joined to one long side surface 22 (here, the upper surface) of the single core wire 21. Note that the method for connecting the first core wires 33 and the single core wire 21 is not particularly limited. For example, ultrasonic welding, laser welding, or the like can be used as the method for connecting the first core wires 33 and the single core wire 21.

[0043] 3, the two electric wire members 20 have two first connection portions 51. The two first connection portions 51 are provided, for example, at positions shifted from each other in the longitudinal direction of the electric wire members 20. That is, the two first connection portions 51 are provided at positions not overlapping each other in the radial direction of the first core wire 33 and the single core wire 21. In other words, the two first connection portions 51 are provided at positions not overlapping each other in the overlapping direction of the single core wire 21 and the first core wire 33 (the up-down direction in the figure).

[0044] (Configuration of electric wire 41) 2 and 3 are more flexible than, for example, the single core wire 21. Each electric wire 41 is more flexible than, for example, the single core wire 21. Each electric wire 41 has higher flexibility than, for example, the single core wire 21.

[0045] Each electric wire 41 has a second core wire 43 made of a plurality of metal wires, and a second insulating coating 44 that surrounds the outer periphery of the second core wire 43 and has insulating properties. Each electric wire 41 has, for example, a cylindrical second individual shield member 45 that surrounds the outer periphery of the second insulating coating 44 and has conductivity, and a second sheath 46 that surrounds the outer periphery of the second individual shield member 45 and has insulating properties. Each electric wire 41 in this embodiment is a shielded electric wire.

[0046] For example, a twisted wire or a braided wire can be used as the second core wire 43. In this embodiment, the second core wire 43 is a twisted wire. For example, a copper-based or aluminum-based metal material can be used as the material for the second core wire 43.

[0047] 6, the second insulating coating 44 covers, for example, the entire circumferential outer surface of the second core wire 43. The second insulating coating 44 is made of, for example, an insulating resin material.

[0048] The second individual shield member 45, for example, surrounds the outer peripheral surface of the second insulating coating 44 over the entire circumferential direction. The second individual shield member 45, for example, has flexibility. The second individual shield member 45 can be made of, for example, a braided wire or a metal foil. The second individual shield member 45 of this embodiment is a braided wire. The second individual shield member 45 can be made of, for example, a copper-based or aluminum-based metal material.

[0049] The second sheath 46, for example, surrounds the entire circumferential circumference of the outer circumferential surface of the second individual shield member 45. The second sheath 46 is made of, for example, an insulating resin material.

[0050] The cross-sectional shape of each electric wire 41 is formed to be, for example, a circular shape. Note that the cross-sectional shape of each electric wire 41 is not limited to a circular shape and may be formed to be any shape such as a semicircular shape, a polygonal shape, a square shape, or a flat shape.

[0051] 3, each electric wire member 20 has one electric wire 41. Therefore, two electric wire members 20 have two electric wires 41. The two electric wires 41 are arranged side by side in a direction intersecting the length direction of the electric wire member 20. The two electric wires 41 are arranged side by side, for example, along the direction in which the multiple single-core wires 21 are arranged (the vertical direction in the figure).

[0052] The front end of the second individual shield member 45 has, for example, a second exposed portion 47 exposed from the second sheath 46. At the front end of each electric wire 41, a predetermined length of the second sheath 46 is stripped from the end of the electric wire 41, and the front end of the second individual shield member 45 is exposed as the second exposed portion 47. Each second exposed portion 47 is, for example, folded back toward the front end of the second sheath 46. The second exposed portion 47 is, for example, folded back so as to cover the outer periphery of the front end of the second sheath 46. Here, an underlying member 48 is attached to the outer periphery of the front end of the second sheath 46. The underlying member 48 is, for example, attached individually to each of the multiple electric wires 41. The underlying member 48 is, for example, a metal ring member. The underlying member 48 is, for example, formed in a ring shape that surrounds the outer periphery of the second sheath 46 in the entire circumferential direction. The second exposed portion 47 is folded back, for example, to cover the outer periphery of the underlying member 48. That is, the second exposed portion 47 surrounds the outer periphery of the underlying member 48. As shown in FIG. 6 , the second exposed portion 47 surrounds, for example, the entire outer periphery of the underlying member 48. The cross-sectional shape of the portion where the underlying member 48 is provided is formed into a structure in which the second insulating coating 44, the second individual shield member 45, the second sheath 46, the underlying member 48, and the second exposed portion 47 are layered in this order on the outer periphery of the second core wire 43. Note that the underlying member 48 can be made of, for example, a copper-based or aluminum-based metal material.

[0053] As shown in FIG. 3 , at the front end of each electric wire 41 provided forward of the second exposed portion 47, the front end of the second core wire 43 is exposed from the second insulating coating 44. At the front end of each electric wire 41, a predetermined length of the second insulating coating 44 is stripped from the end of the electric wire 41, exposing the front end of the second core wire 43. At each second connection portion 52, the front end of the second core wire 43 exposed from the second insulating coating 44 is joined to the rear end of the single core wire 21. For example, at each second connection portion 52, the second core wire 43 and the single core wire 21 are joined by overlapping each other in the radial direction, that is, in a direction intersecting the length directions of the second core wire 43 and the single core wire 21. For example, at each second connection portion 52, one second core wire 43 is joined by overlapping each other on the long side surface 22 (here, the upper surface) of the single core wire 21. 2 , in each electric wire member 20 of this embodiment, the first core wire 33 of the electric wires 31 and 32 is joined to the front end of one long side surface 22 of each single core wire 21, and the second core wire 43 of the electric wire 41 is joined to the rear end of the one long side surface 22. That is, the first core wire 33 of the electric wires 31 and 32 is joined to one long side surface 22 of the pair of long side surfaces 22 of each single core wire 21, and the second core wire 43 of the electric wire 41 is joined to that long side surface 22. Note that the method for connecting the second core wire 43 to the single core wire 21 is not particularly limited. For example, ultrasonic welding, laser welding, or the like can be used as the method for connecting the second core wire 43 to the single core wire 21.

[0054] 3, the two electric wire members 20 have two second connection portions 52. The two second connection portions 52 are provided, for example, at positions shifted from each other in the longitudinal direction of the electric wire members 20. That is, the two second connection portions 52 are provided at positions not overlapping each other in the radial direction of the electric wire 41 and the single core wire 21. In other words, the two second connection portions 52 are provided at positions not overlapping each other in the overlapping direction of the single core wire 21 and the second core wire 43 (the up-down direction in the figure).

[0055] Here, the multiple single core wires 21 differ from one another in, for example, lengthwise dimension. For example, the single core wire 21 arranged on the upper side in the drawing is formed shorter than the single core wire 21 arranged on the lower side in the drawing. For this reason, the single core wire 21 on the upper side in the drawing is not arranged above the rear end of the single core wire 21 arranged on the lower side in the drawing, and the single core wire 21 on the upper side in the drawing is not arranged above the front end of the single core wire 21 arranged on the lower side in the drawing. Therefore, the first connection portion 51 of the electric wire member 20 arranged on the lower side in the drawing overlaps with a part of the single core wire 21 arranged on the upper side in the drawing in the lengthwise direction of the electric wire member 20. Not It can be set up as follows.

[0056] (Configuration of covering member 60) The covering member 60 is provided on each of the plurality of electric wire members 20, for example. Each covering member 60 is formed so as to cover the outer periphery of the first connection portion 51. Each covering member 60 is formed, for example, in a long, cylindrical shape. As shown in FIG. 2 , each covering member 60 is formed so as to cover, for example, the first core wire 33 of each electric wire 31, 32 exposed from the first insulating covering 34. Each covering member 60 is formed so as to cover, for example, at least the rear end of the first insulating covering 34 of each electric wire 31, 32 to the first connection portion 51. Each covering member 60 is formed, for example, so as to cover the outer periphery of the single core wire 21 over the entire length of the single core wire 21 in the longitudinal direction. Each covering member 60 is formed, for example, so as to cover the outer periphery of the second connection portion 52. Each covering member 60 is formed, for example, so as to cover the second core wire 43 exposed from the second insulating covering 44. Each covering member 60 is formed, for example, to cover the electric wires 31, 32 from the rear end of the first insulating covering 34 to the front end of the second insulating covering 44. For example, the front end of each covering member 60 covers the outer peripheral surface of the rear end of the first insulating covering 34 of the electric wires 31, 32, and the rear end of each covering member 60 covers the outer peripheral surface of the front end of the second insulating covering 44. Each covering member 60 surrounds the outer periphery of the single core wire 21, the outer periphery of the electric wires 31, 32, and the outer periphery of the electric wire 41 over the entire circumferential direction. Each covering member 60 is formed, for example, to expose the first individual shielding member 35 of the electric wires 31, 32 and the second individual shielding member 45. In other words, each covering member 60 is formed, for example, so as not to cover the outer periphery of the first individual shielding member 35 of the electric wires 31, 32. The covering member 60 is formed, for example, so as not to cover the outer periphery of the second individual shielding member 45. Each covering member 60 covers, for example, the outer peripheral surface of the rear end of the first insulating covering 34 exposed from the first exposed portion 37 and the first sheath 36, and also covers the outer peripheral surface of the front end of the second insulating covering 44 exposed from the second exposed portion 47 and the second sheath 46. The inner peripheral surface of each covering member 60 is formed, for example, to be in close contact with the outer peripheral surface of the first insulating covering 34. The inner peripheral surface of each covering member 60 is formed, for example, to be in close contact with the outer peripheral surface of the second insulating covering 44. The inner peripheral surface of each covering member 60 is formed, for example, to be in close contact with the outer peripheral surface of the single core wire 21.Each covering member 60 has a function of maintaining electrical insulation among, for example, the first connecting portion 51, the second connecting portion 52, the single core wire 21, the first core wire 33 exposed from the first insulating covering 34, and the second core wire 43 exposed from the second insulating covering 44. Each covering member 60 also has a function of waterproofing, for example, the first connecting portion 51, the second connecting portion 52, the single core wire 21, the first core wire 33 exposed from the first insulating covering 34, and the second core wire 43 exposed from the second insulating covering 44.

[0057] The covering member 60 may be, for example, a heat shrinkable tube, a rubber tube, a resin mold, a hot melt adhesive, or a tape. The covering member 60 in this embodiment is a heat shrinkable tube. The covering member 60 may be made of, for example, a synthetic resin containing a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene as its main component.

[0058] (Configuration of cylindrical member 71) The cylindrical member 71 is formed, for example, in a long cylindrical shape. A plurality of electric wire members 20 are housed in the internal space of the cylindrical member 71. The cylindrical member 71 is formed to surround the outer peripheries of the plurality of electric wire members 20 over the entire circumferential direction. The cylindrical member 71 is formed, for example, to surround only the outer peripheries of a portion of the electric wire members 20 in the longitudinal direction, in this case, a middle portion. The cylindrical member 71 surrounds, for example, the outer peripheries of the single core wires 21 in the longitudinal direction of each electric wire member 20. The cylindrical member 71 surrounds, for example, the outer peripheries of each single core wire 21 over the entire length of the single core wire 21 in the longitudinal direction. The cylindrical member 71 surrounds, for example, the outer peripheries of the first connecting portion 51 and the second connecting portion 52 of each electric wire member 20 in the longitudinal direction. The cylindrical member 71, for example, surrounds the outer periphery of the rear end portion of the first insulating coating 34 of the electric wires 31, 32 and surrounds the outer periphery of the front end portion of the second insulating coating 44 of the electric wire 41 in the longitudinal direction of each electric wire member 20. The cylindrical member 71 is formed, for example, in the longitudinal direction of each electric wire member 20, so as to expose the first individual shield members 35 of the electric wires 31, 32 and the second individual shield member 45. In other words, the first individual shield members 35 of the electric wires 31, 32 are arranged outside the cylindrical member 71. The second individual shield member 45 is arranged outside the cylindrical member 71.

[0059] The cylindrical member 71 of this embodiment is a conductive shielded pipe. For example, a metal pipe made of metal can be used as the cylindrical member 71. For example, a copper-based or aluminum-based metal material can be used as the material of the cylindrical member 71. The cylindrical member 71, which is a shielded pipe, has an electromagnetic shielding function that suppresses radiation of electromagnetic waves from the electric wire member 20, for example.

[0060] The cross-sectional shape of the cylindrical member 71 can be any shape. The cross-sectional shape of the cylindrical member 71 is formed, for example, in a circular shape, a semicircular shape, a polygonal shape, a square shape, or a flat shape. The cross-sectional shape of the cylindrical member 71 can be set, for example, to a shape corresponding to the cross-sectional shape of the single-core wire 21. As shown in FIG. 4, the cross-sectional shape of the cylindrical member 71 of this embodiment is formed in a quadrangular shape. That is, the cylindrical member 71 of this embodiment is formed in a rectangular tube shape in which the cross-sectional shapes of the inner periphery and the outer periphery are quadrangular.

[0061] The cylindrical member 71 can be formed by, for example, extrusion molding. The cylindrical member 71 is formed so that its cross section has a constant shape over the entire length of the cylindrical member 71 in the longitudinal direction (axial direction).

[0062] (Grounding structure of first individual shield member 35, second individual shield member 45, and cylindrical member 71) As shown in FIG. 2 , the wire harness 10 includes, for example, a first shielding member 91 having a conductive cylindrical shape and a second shielding member 92 having a conductive cylindrical shape. The wire harness 10 includes, for example, a connecting member 93 that connects a front end of the first shielding member 91 to the first individual shielding member 35 and a connecting member 94 that connects a rear end of the first shielding member 91 to a front end of the tubular member 71. The wire harness 10 includes, for example, a connecting member 95 that connects a rear end of the second shielding member 92 to the second individual shielding member 45 and a connecting member 96 that connects a front end of the second shielding member 92 to the rear end of the tubular member 71. Each of the first shielding member 91 and the second shielding member 92 is, for example, flexible. The first shielding member 91 and the second shielding member 92 can be, for example, a braided wire or a metal foil. In this embodiment, the first shielding member 91 and the second shielding member 92 are each a braided wire. The first shielding member 91 and the second shielding member 92 may be made of, for example, a copper-based or aluminum-based metal material. The connecting members 93, 94, 95, and 96 may be made of, for example, a crimping ring, a cable tie, or a tape member. The connecting members 93, 94, 95, and 96 in this embodiment are crimping rings. The crimping rings may be made of, for example, an iron-based, aluminum-based, or copper-based metal material.

[0063] The first shielding member 91 is formed, for example, in a long cylindrical shape. The first shielding member 91 is formed, for example, so as to surround the outer peripheries of the portions of the plurality of electric wire members 20 that are exposed from the first individual shielding member 35 and the cylindrical member 71. The first shielding member 91 is formed, for example, so as to bridge between the first exposed portions 37 of the electric wires 31, 32 and the front end portion of the cylindrical member 71 in the longitudinal direction of the electric wire member 20. The first shielding member 91 is formed, for example, so as to collectively surround the outer peripheries of the plurality of electric wires 31, 32 that are provided between the first exposed portions 37 and the cylindrical member 71. A front end portion (first end portion), which is one end portion of the first shielding member 91 in the axial direction (lengthwise direction), is formed, for example, so as to cover the outer peripheries of the first exposed portions 37 of the electric wires 31, 32. As shown in FIG. 5 , the front end portion of the first shielding member 91 is formed, for example, so as to collectively surround the outer peripheries of the plurality of first exposed portions 37 (four in this embodiment). The front end of the first shielding member 91 is arranged to overlap the underlay member 38 in the radial direction of the electric wire members 20, for example. The first shielding member 91 surrounds, for example, the outer peripheries of the plurality of electric wire members 20 over the entire circumferential direction. As shown in FIG. 3, the rear end (second end), which is the other end in the axial direction of the first shielding member 91, is formed to surround, for example, the outer periphery of the front end of the tubular member 71. As shown in FIG. 7, the first shielding member 91 surrounds, for example, the outer periphery of the tubular member 71 over the entire circumferential direction.

[0064] As shown in FIG. 5 , the connecting member 93 fixes the front end of the first shielding member 91 to the outer circumferential surfaces of the electric wires 31 and 32, for example, with the front end of the first shielding member 91 in contact with the first exposed portions 37. The connecting member 93 is attached to the outer circumferential surface of the underlying member 38, for example. The connecting member 93 is formed, for example, in a ring shape along the outer circumferential surfaces of the plurality of underlying members 38. The connecting member 93 is fitted to the outside of the underlying member 38 in such a manner that the front end of the first shielding member 91 and the first exposed portions 37 are sandwiched between the connecting member 93 and the outer circumferential surface of the underlying member 38. The connecting member 93 is then fastened to the radially inner side of the electric wire member 20, whereby the front end of the first shielding member 91 is fixed to the outer circumferential surfaces of the electric wires 31 and 32 with the front end of the first shielding member 91 in direct contact with the outer circumferential surfaces of the plurality of first exposed portions 37. For example, the front end of the first shielding member 91 is in partial direct contact with all four of the first exposed portions 37. In other words, all four first exposed portions 37 are in direct contact with the first shielding member 91. As a result, the first shielding member 91 is electrically and mechanically connected to the multiple first exposed portions 37. At the connection portions between the first exposed portions 37 and the first shielding member 91, the multiple first exposed portions 37 are bundled together so as to be in contact with one another. For example, the outer circumferential surface of each first exposed portion 37 is in partial direct contact with the outer circumferential surface of an adjacent first exposed portion 37.

[0065] As shown in FIG. 7 , the connecting member 94 fixes the rear end of the first shielding member 91 to the outer circumferential surface of the tubular member 71, for example, with the rear end of the first shielding member 91 in contact with the outer circumferential surface of the tubular member 71. The connecting member 94 is attached to the outer circumferential surface of the tubular member 71. The connecting member 94 is formed, for example, in a ring shape along the outer circumferential surface of the tubular member 71. The connecting member 94 of this embodiment is formed in a rectangular tubular shape. The connecting member 94 is fitted to the outside of the tubular member 71, for example, in a manner that sandwiches the rear end of the first shielding member 91 between the connecting member 94 and the outer circumferential surface of the tubular member 71. Then, by tightening the connecting member 94 radially inward of the tubular member 71, the rear end of the first shielding member 91 is fixed to the outer circumferential surface of the tubular member 71 in direct contact with the outer circumferential surface of the tubular member 71. This electrically and mechanically connects the first shielding member 91 to the tubular member 71.

[0066] 2, the first exposed portions 37 of the electric wires 31, 32 (i.e., the first individual shield members 35) and the cylindrical member 71 are electrically connected via the first shield member 91. Although not shown, the front end of each of the first individual shield members 35 is earth-connected (earthed) to a vehicle body panel or the like via connectors C2, C3 (see FIG. 1), for example. This allows the first individual shield member 35, the first shield member 91, and the cylindrical member 71 to be earth-connected.

[0067] The second shielding member 92 is formed, for example, in a long cylindrical shape. The second shielding member 92 is formed, for example, so as to surround the outer peripheries of the portions of the plurality of electric wire members 20 that are exposed from the second individual shielding members 45 and the cylindrical member 71. The second shielding member 92 is formed, for example, so as to bridge between the second exposed portions 47 and the rear end portion of the cylindrical member 71 in the longitudinal direction of the electric wire member 20. The second shielding member 92 is formed, for example, so as to collectively surround the outer peripheries of the plurality of electric wires 41 provided between the second exposed portions 47 and the cylindrical member 71. The rear end portion, which is one end of the second shielding member 92 in the axial direction (lengthwise direction), is formed, for example, so as to cover the outer peripheries of the second exposed portions 47 of the electric wires 41. As shown in FIG. 6 , the rear end portion of the second shielding member 92 is formed, for example, so as to collectively surround the outer peripheries of the plurality of second exposed portions 47. The rear end portion of the second shielding member 92 is arranged, for example, so as to overlap with the underlay member 48 in the radial direction of the electric wire member 20. The second shielding member 92, for example, surrounds the outer periphery of the plurality of wire members 20 over the entire circumferential direction. As shown in Fig. 3, the front end portion, which is the other end portion in the axial direction of the second shielding member 92, is formed to surround the outer periphery of the rear end portion of the tubular member 71, for example. The second shielding member 92 surrounds the outer periphery of the tubular member 71 over the entire circumferential direction.

[0068] As shown in FIG. 6 , the connecting member 95 secures the rear end of the second shielding member 92 to the outer circumferential surfaces of the second exposed portions 47, for example, with the rear end of the second shielding member 92 in contact with the second exposed portions 47. The connecting member 95 is attached to the outer circumferential surface of the underlying member 48, for example. The connecting member 95 is formed, for example, in a ring shape along the outer circumferential surfaces of the plurality of underlying members 48. The connecting member 95 is fitted to the outside of the underlying member 48, for example, in a manner that sandwiches the rear end of the second shielding member 92 and the second exposed portions 47 between the connecting member 95 and the outer circumferential surface of the underlying member 48. The connecting member 95 is then fastened to the radially inner side of the wire member 20, whereby the rear end of the second shielding member 92 is secured to the outer periphery of the wire 41 in direct contact with the outer circumferential surfaces of the plurality of second exposed portions 47. For example, the rear end of the second shielding member 92 is in partial direct contact with all of the two second exposed portions 47. In other words, all of the two second exposed portions 47 are in direct contact with the second shielding member 92. This electrically and mechanically connects the second shielding member 92 to the multiple second exposed portions 47. At the connection portion between the second exposed portions 47 and the second shielding member 92, the multiple second exposed portions 47 are bundled together so as to be in contact with each other. For example, the outer circumferential surface of each second exposed portion 47 is in partial direct contact with the outer circumferential surface of the other second exposed portion 47.

[0069] The connecting member 96 fixes the front end of the second shielding member 92 to the outer peripheral surface of the cylindrical member 71, for example, with the front end of the second shielding member 92 in contact with the outer peripheral surface of the cylindrical member 71. The connecting member 96 is attached to the outer peripheral surface of the cylindrical member 71. The connecting member 96 is formed in a ring shape that follows the outer peripheral surface of the cylindrical member 71. The connecting member 96 of this embodiment is formed in a rectangular cylindrical shape. The connecting member 96 is fitted to the outside of the cylindrical member 71, for example, in a manner that sandwiches the front end of the second shielding member 92 between the connecting member 96 and the outer peripheral surface of the cylindrical member 71. Then, by tightening the connecting member 96 radially inward of the cylindrical member 71, the front end of the second shielding member 92 is fixed to the outer peripheral surface of the cylindrical member 71 with the front end being in direct contact with the outer peripheral surface of the cylindrical member 71. This electrically and mechanically connects the second shielding member 92 to the cylindrical member 71.

[0070] 3, the second exposed portion 47 (i.e., the second individual shield member 45) and the tubular member 71 are electrically connected via the second shield member 92. Although not shown, the rear end of each second individual shield member 45 is earth-connected (earthed) to a vehicle body panel or the like via a connector C1 (see FIG. 1), for example. This allows the second individual shield member 45, the second shield member 92, and the tubular member 71 to be earth-connected.

[0071] (Waterproof structure of wire harness 10) As shown in FIG. 2 , the wire harness 10 includes, for example, a fixing member 83 that fixes the front end of the waterproofing member 81 to the electric wire member 20 and a fixing member 84 that fixes the rear end of the waterproofing member 81 to the tubular member 71. The wire harness 10 includes, for example, a fixing member 85 that fixes the rear end of the waterproofing member 82 to the electric wire member 20 and a fixing member 86 that fixes the front end of the waterproofing member 82 to the tubular member 71. The waterproofing members 81 and 82 may be, for example, shrinkable tubes or rubber tubes. The shrinkable tube may be made of, for example, a synthetic resin containing a polyolefin resin, such as cross-linked polyethylene or cross-linked polypropylene, as a main component. The fixing members 83, 84, 85, and 86 may be, for example, crimping rings, cable ties, or tape members. In this embodiment, the fixing members 83, 84, 85, and 86 are each a cable tie.

[0072] The waterproof member 81 is formed, for example, in the shape of a long tube. The waterproof member 81 is formed, for example, so as to collectively surround the outer peripheries of the multiple electric wires 31, 32. The waterproof member 81 is formed, for example, so as to cover the outer peripheries of the electric wires 31, 32 protruding forward from the front end of the tubular member 71. The waterproof member 81 is formed, for example, so as to cover the outer periphery of the first exposed portion 37. The waterproof member 81 is formed, for example, so as to cover the outer peripheries of the first shielding member 91 and the connecting members 93, 94. The waterproof member 81 is formed, for example, so as to bridge between the electric wires 31, 32 arranged forward of the first exposed portion 37 and the outer periphery of the tubular member 71 arranged rearward of the connecting member 94. For example, the front end of the waterproof member 81 covers the electric wires 31, 32 arranged forward of the first exposed portion 37, and the rear end of the waterproof member 81 covers the outer periphery of the tubular member 71 arranged rearward of the connecting member 94. The waterproof member 81 surrounds the outer periphery of the electric wire member 20 and the outer periphery of the cylindrical member 71 over the entire circumferential direction.

[0073] The front end of the waterproofing member 81 is bonded, for example, by an adhesive 87 over the entire circumferential direction to the outer circumferential surfaces of the electric wires 31, 32 arranged forward of the first exposed portion 37. As the adhesive 87, for example, a hot melt adhesive of polyolefin resin, polyester resin, polyamide resin, or the like can be used.

[0074] The adhesive 87, for example, seals the gap between the outer circumferential surfaces of the electric wires 31, 32 arranged forward of the first exposed portion 37 and the inner circumferential surface of the waterproofing member 81. The adhesive 87 is formed, for example, to fill gaps between the outer circumferential surfaces of the electric wires 31, 32 and the inner circumferential surface of the waterproofing member 81. The adhesive 87 is formed, for example, to fill gaps between the electric wires 31, 32 and the electric wires 31, 32. The adhesive 87 is in close contact with the inner circumferential surface of the waterproofing member 81 over the entire circumferential direction, and is in close contact with the outer circumferential surfaces of the electric wires 31, 32 over the entire circumferential direction. This makes it possible to prevent liquids such as water from entering the waterproofing member 81 from the front end of the waterproofing member 81.

[0075] A fixing member 83 is provided on the outer peripheral surface of the front end portion of the waterproofing member 81. The front end portion of the waterproofing member 81 is fastened from the outer peripheral side by the fixing member 83 and fixed to the electric wires 31, 32. The front end portion of the waterproofing member 81 is fixed to the outer peripheral surfaces of the electric wires 31, 32 via an adhesive 87, for example, by being fastened radially inward by the fixing member 83.

[0076] A fixing member 84 is provided on the outer peripheral surface of the rear end portion of the waterproof member 81. The rear end portion of the waterproof member 81 is fastened from the outer peripheral side by the fixing member 84 and fixed to the tubular member 71. For example, the rear end portion of the waterproof member 81 is fastened from the outer peripheral side by the fixing member 84 until it comes into liquid-tight contact with the outer peripheral surface of the tubular member 71. This makes it possible to prevent liquids such as water from entering the interior of the waterproof member 81 from between the waterproof member 81 and the tubular member 71.

[0077] The waterproof member 82 is formed, for example, in the shape of a long tube. The waterproof member 82 is formed, for example, so as to collectively surround the outer peripheries of the multiple electric wires 41. The waterproof member 82 is formed, for example, so as to cover the outer peripheries of the electric wires 41 protruding rearward from the rear end of the tubular member 71. The waterproof member 82 is formed, for example, so as to cover the outer periphery of the second exposed portion 47. The waterproof member 82 is formed, for example, so as to cover the outer peripheries of the second shielding member 92 and the connecting members 95, 96. The waterproof member 82 is formed, for example, so as to bridge between the electric wires 41 arranged rearward from the second exposed portion 47 and the outer periphery of the tubular member 71 arranged forward from the connecting member 96. For example, the rear end of the waterproof member 82 covers the electric wires 41 arranged rearward from the second exposed portion 47, and the front end of the waterproof member 82 covers the outer periphery of the tubular member 71 arranged forward from the connecting member 96. The waterproof member 82 surrounds the outer periphery of the electric wire member 20 and the outer periphery of the cylindrical member 71 over the entire circumferential direction.

[0078] The rear end of the waterproofing member 82 is bonded, for example, by an adhesive 88 over the entire circumferential direction to the outer circumferential surface of the electric wire 41 disposed rearward of the second exposed portion 47. As the adhesive 88, for example, a hot melt adhesive such as a polyolefin resin, a polyester resin, or a polyamide resin can be used.

[0079] The adhesive 88, for example, seals the gap between the outer circumferential surface of the electric wire 41 arranged rearward of the second exposed portion 47 and the inner circumferential surface of the waterproofing member 82. The adhesive 88 is formed, for example, so as to fill the gap between the outer circumferential surface of the electric wire 41 and the inner circumferential surface of the waterproofing member 82. The adhesive 88 is formed so as to fill the gap between the electric wires 41. For example, the adhesive 88 is in close contact with the inner circumferential surface of the waterproofing member 82 over the entire circumferential direction without any gaps, and is in close contact with the outer circumferential surface of each electric wire 41 over the entire circumferential direction without any gaps. This makes it possible to prevent liquids such as water from entering the interior of the waterproofing member 82 from the rear end portion of the waterproofing member 82.

[0080] A fixing member 85 is provided on the outer peripheral surface of the rear end portion of the waterproofing member 82. The rear end portion of the waterproofing member 82 is fastened from the outer peripheral side by the fixing member 85 and fixed to the electric wire 41. The rear end portion of the waterproofing member 82 is fixed to the outer peripheral surface of the electric wire 41 via an adhesive 88, for example, by being fastened radially inward by the fixing member 85.

[0081] A fixing member 86 is provided on the outer peripheral surface of the front end portion of the waterproof member 82. The front end portion of the waterproof member 82 is fastened from the outer peripheral side by the fixing member 86 and fixed to the tubular member 71. For example, the front end portion of the waterproof member 82 is fastened from the outer peripheral side by the fixing member 86 until it comes into liquid-tight contact with the outer peripheral surface of the tubular member 71. This makes it possible to prevent liquids such as water from entering the interior of the waterproof member 82 from between the waterproof member 82 and the tubular member 71.

[0082] Next, the effects of this embodiment will be described. (1) The first shield member 91 is electrically connected to the first individual shield member 35 while being in contact with the multiple first exposed portions 37, and is also electrically connected to the tubular member 71. This allows the first individual shield member 35 and the tubular member 71 to be electrically connected via the first shield member 91. Therefore, the first shield member 91, the first individual shield member 35, and the tubular member 71 can provide suitable electromagnetic shielding for the wire member 20. Here, the first shield member 91 is provided to surround the outer periphery of the portion of the multiple electric wire members 20 that is exposed from the first individual shield member 35 and the tubular member 71. Therefore, even if the electric wire member 20 has a portion that is exposed from the first individual shield member 35 and the tubular member 71, the exposed portion can be surrounded by the first shield member 91 that is separate from the first individual shield member 35 and the tubular member 71. This allows the electric wire member 20 at the exposed portion to be suitably electromagnetically shielded by the first shield member 91. Therefore, even if the wire member 20 has a portion exposed from the first individual shield member 35 and the tubular member 71, it is possible to preferably prevent a decrease in the electromagnetic shielding performance at the exposed portion. As a result, it is possible to preferably prevent electromagnetic waves generated at the exposed portion from being radiated to the outside of the wire harness 10.

[0083] (2) The first shielding member 91 is formed to bridge between the multiple first exposed portions 37 and the cylindrical member 71. Furthermore, the first shielding member 91 is formed to collectively surround the outer peripheries of the multiple first exposed portions 37, and is also formed to surround the outer periphery of the cylindrical member 71 over the entire circumferential direction. Therefore, the outer peripheries of the multiple electric wires 31, 32 provided between the first exposed portions 37 and the cylindrical member 71 can be surrounded by a single first shielding member 91, and the multiple electric wires 31, 32 can be suitably electromagnetically shielded by the first shielding member 91.

[0084] (3) An underlying member 38, which is a metal ring member, is interposed between the first sheath 36 and the first exposed portions 37. The multiple first exposed portions 37 and the first shield member 91 are sandwiched between this underlying member 38 and the connecting member 93. As a result, when the connecting member 93 is tightened to the multiple first exposed portions 37, the underlying member 38 is interposed between the first exposed portions 37 and the first sheath 36, so deformation of the electric wires 31, 32 can be suppressed. As a result, the stability of the electrical connection between the first exposed portions 37 and the first shield member 91 can be improved. Furthermore, because the underlying member 38 is attached to each of the multiple electric wires 31, 32, deformation of each of the multiple electric wires 31, 32 can be suitably suppressed.

[0085] (4) The connection portion between the multiple first exposed portions 37 and the first shielding member 91 has a structure in which the multiple first exposed portions 37 are bundled together so that they are in contact with one another, and each of the multiple first exposed portions 37 is in contact with the first shielding member 91. With this configuration, each of the multiple first exposed portions 37 is in direct contact with the first shielding member 91, thereby improving the stability of the electrical connection between the multiple first exposed portions 37 and the first shielding member 91.

[0086] (Other embodiments) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0087] In the above embodiment, the first connection portions 51 are arranged at positions offset from one another in the length direction of the electric wire member 20, but the present invention is not limited to this. For example, as shown in Fig. 8, the multiple first connection portions 51 may be arranged side by side in the length direction of the electric wire member 20. For example, the multiple first connection portions 51 may be arranged at the same positions as each other in the length direction of the electric wire member 20. That is, the multiple first connection portions 51 may be provided at positions where they overlap each other in the radial direction of the single core wire 21 and the electric wire 31. In other words, the multiple first connection portions 51 may be provided so as to overlap each other in the overlapping direction of the single core wire 21 and the electric wires 31, 32 (the up-down direction in the figure). Similarly, the multiple second connection portions 52 may be arranged at the same positions as each other in the length direction of the electric wire member 20.

[0088] In the above embodiment, the lengths of the plurality of single core wires 21 are set to be different from each other, but this is not limitative. For example, the lengths of the plurality of single core wires 21 may be set to be the same. In the above embodiment, the first core wire 33 of the electric wires 31, 32 is joined to one long side surface 22 of one single core wire 21, and the second core wire 43 of the electric wire 41 is joined to that long side surface 22. However, this is not limiting. For example, the first core wire 33 may be joined to one long side surface 22 of one single core wire 21, and the second core wire 43 may be joined to the other long side surface 22. Alternatively, the first core wire 33 of the electric wire 31 may be joined to one long side surface 22 of one single core wire 21, and the first core wire 33 of the electric wire 32 may be joined to the other long side surface 22.

[0089] In the above embodiment, the first core wire 33 and the second core wire 43 are joined to the long side surface 22 of the single core wire 21, but this is not limiting. For example, the first core wire 33 and the second core wire 43 may be joined to the short side surface 23 of the single core wire 21.

[0090] In the above embodiment, there is no particular limitation on the arrangement direction of the single-core wires 21. For example, the single-core wires 21 may be arranged so that the short sides 23 face each other. In the above embodiment, the plurality of electric wires 31, 32 are connected to the front end portion of one single core wire 21, but the present invention is not limited to this.

[0091] 9, for example, only one electric wire 31 may be connected to the front end of one single core wire 21. In this case, the first shielding member 91 is electrically connected to the first exposed portion 37 (first individual shielding member 37) of the electric wire 31.

[0092] In the above embodiment, the electric wires 31, 32 are connected to the front end of the single core wire 21, and the electric wire 41 is connected to the rear end of the single core wire 21. That is, the other electric wires 31, 32, 41 are connected to both ends of the single core wire 21 in the length direction. However, this is not limiting. For example, the other electric wire may be connected to only one of both ends of the single core wire 21 in the length direction.

[0093] In the above embodiment, the conductive member is embodied as a single-core wire 21, but this is not limiting. For example, the conductive member may be embodied as a metal connection terminal provided inside a connector C1 or the like. In this case, the cylindrical member 71 may be embodied as a metal shield shell of the connector C1 or the like. Furthermore, the conductive member may be embodied as a non-shielded electric wire or a shielded electric wire that does not have an electromagnetic shield structure itself.

[0094] In the above embodiment, an insulating coating may be provided to cover the outer periphery of each single core wire 21. In this case, the covering member 60 is formed, for example, to cover the outer periphery of the insulating coating that covers the outer periphery of the single core wire 21. In addition, the covering member 60 in this case does not need to cover the outer periphery of the single core wire 21 over the entire length.

[0095] The fixing members 83 and 85 in the above embodiment may be omitted. In the above embodiment, the waterproof member 81 may be omitted. In this case, the fixing members 83 and 84 and the adhesive 87 can be omitted.

[0096] In the above embodiment, the waterproof member 82 may be omitted. In this case, the fixing members 85 and 86 and the adhesive 88 can be omitted. In the above embodiment, the first exposed portion 37 is folded back toward the rear end of the first sheath 36, but it may be modified to a structure in which it is not folded back.

[0097] In the above embodiment, the second exposed portion 47 is folded back toward the front end of the second sheath 46, but it may be modified to a structure in which it is not folded back. The underlay members 38, 48 in the above embodiment may be omitted.

[0098] The second shield member 92 in the above embodiment may be omitted. In this case, the connecting members 95 and 96 can be omitted. In the above embodiment, the first connection portion 51 may be disposed on the outside of the cylindrical member 71 .

[0099] In the above embodiment, the second connection portion 52 may be disposed on the outside of the cylindrical member 71 . In the above embodiment, two electric wires, the electric wire 31 and the electric wire 32, are connected to the front end portion of one single core wire 21, but this is not limiting. For example, three or more electric wires may be connected to the front end portion of one single core wire 21.

[0100] In the above embodiment, the cylindrical member 71 is embodied as a metal pipe, but is not limited to this. For example, the cylindrical member 71 is not limited to a metal pipe as long as it is a cylindrical shielding member. For example, the cylindrical member 71 may be a member obtained by processing a shielding member such as a braided wire into a cylindrical shape. Furthermore, the cylindrical member 71 may be formed by a corrugated tube and a shielding member such as a braided wire surrounding the outer periphery of the corrugated tube.

[0101] In the above embodiment, the electric wire 41 is a shielded electric wire, but this is not limiting. For example, the electric wire 41 may be a non-shielded electric wire. The number of electric wire members 20 constituting the wire harness 10 of the above embodiment is not particularly limited. For example, the number of electric wire members 20 may be three or more.

[0102] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the above meaning, and is intended to include all modifications within the meaning and scope of the claims.
