[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. [1] The wire harness of the present disclosure comprises a first shielded wire, a group of wires including a second shielded wire and a third shielded wire, and a connection structure connecting the first shielded wire and the group of wires, wherein the first, second and third shielded wires comprise a core wire, an inner insulating cover covering the core wire, individual shielding members covering the inner insulating cover, and an outer insulating cover covering the individual shielding members, wherein the connection structure comprises a core wire connection portion, a connection portion insulating cover covering the core wire connection portion, exposed portions where each of the individual shielding members is exposed, and a connection portion arranged to cover the connection portion insulating cover. The shielding member comprises a shielding member, a first holding member that holds the connecting shielding member in a state where it is pressed against the exposed portion of the first shield wire, a second holding member that holds the connecting shielding member in a state where it is pressed against the exposed portions of the second shield wire and the third shield wire, and a support member that is positioned opposite the second holding member and supports the exposed portions of the second shield wire and the third shield wire, wherein the support member has a restricting portion that restricts the exposed portions of the second shield wire and the third shield wire from entering between the second shield wire and the third shield wire.

[0010] This configuration prevents the exposed portion to which the connecting shield member is pressed from entering between the second shield wire and the third shield wire. This makes it possible to improve the contact between the connecting shield member and the exposed portion between the second support member and the second holding member. In other words, it is possible to improve the contact of the connecting shield member with each individual shield member of the second shield wire and the third shield wire between the support member and the second holding member. Therefore, it is possible to improve the reliability of the electrical connection between the connecting shield member and the individual shield members.

[0011] [2] In the above [1], the support member may have a shape that surrounds the outer insulating coating of each of the second shield wire and the third shield wire together. With this configuration, for example, displacement of the support member can be easily suppressed. Also, for example, since the support member can support the exposed portion around the entire circumference of the wire group, it is possible to further improve the adhesion of the exposed portion to the connecting shield member.

[0012] [3] In the above [1], the support member may have a shape that surrounds the inner insulating coating of each of the second shield wire and the third shield wire together. Even if the configuration of the above [2] is changed in this way, for example, displacement of the support member can be easily suppressed. Also, for example, since the exposed portion can be supported around the entire circumference of the wire group by the support member, it is possible to further improve the adhesion of the exposed portion to the connecting shield member.

[0013] [4] In the above [2] or [3], the support member may be made of a metal plate and may have an overlapping portion where the ends of the metal plate overlap. With this configuration, the rigidity of the support member can be easily increased by the overlapping portion of the support member. For this reason, the function of the support member having the restricting portion can be easily improved.

[0014] [5] In [4] above, the overlapping portion of the support member may constitute the restricting portion. According to this configuration, the rigidity of the restricting portion of the support member can be easily increased. Therefore, the function of the restricting portion can be easily enhanced.

[0015] [6] In any one of [1] to [5] above, the exposed portion where the individual shield member of the second shielded wire is exposed is folded back so as to overlap the outer peripheral surface of the outer insulating coating of the second shielded wire, and the exposed portion where the individual shield member of the third shielded wire is exposed is folded back so as to overlap the outer peripheral surface of the outer insulating coating of the third shielded wire, and the support member may be disposed between the outer insulating coating of each of the second shielded wire and the third shielded wire and the exposed portion. According to this configuration, for example, the support member can be easily disposed.

[0016] [7] In any one of [1] to [6] above, the support member may have conductivity. According to this configuration, a conductive path using the support member can be ensured. Thereby, it becomes possible to enhance the conductivity between the connection shield member and the individual shield members of the second shield member and the third shield member using the support member.

[0017] [8] In any one of [1] to [7] above, the individual shield members of each of the second shielded wire and the third shielded wire are braided members, and the restricting portion of the support member may restrict the strands constituting the braided member from entering between the second shielded wire and the third shielded wire. According to this configuration, it is possible to restrict the strands of the braided member from entering between the second shielded wire and the third shielded wire. Therefore, it becomes possible to enhance the reliability of the electrical connection between the connection shield member and the braided member which is the individual shield member.

[0018] [9] In any one of the above [1] to [8], between the restricting portion of the support member and the second holding member, a laminated portion of the exposed portion of the second shielded wire and the connection shield member, and a laminated portion of the exposed portion of the third shielded wire and the connection shield member may be sandwiched. According to this configuration, the adhesion between the individual shield member of the second shielded wire and the connection shield member can be enhanced between the restricting portion of the support member and the second holding member. Also, the adhesion between the individual shield member of the third shielded wire and the connection shield member can be enhanced between the restricting portion of the support member and the second holding member.

[0019] [Details of Embodiments of the Present Disclosure] A specific example of the wire harness of the present disclosure will be described below based on the drawings. In each drawing, for convenience of explanation, a part of the configuration may be shown exaggeratedly or simplified. Also, the dimensional ratios of each part may be different in each drawing. In this specification, "orthogonal" and "parallel" include not only the cases of strict orthogonality and parallelism, but also the cases that are generally orthogonal and parallel within the range where the effects of the present embodiment are achieved. The "cylindrical" used in the description of this specification includes not only those in which a circumferential wall is continuously formed over the entire circumference in the circumferential direction, but also those formed by combining a plurality of parts into a cylindrical shape, and those having a notch or the like in a part of the circumferential direction such as a C shape or a U shape. Note that the shape of the "cylindrical" includes, but is not limited to, a circular shape, an elliptical shape, and a polygon having sharp or rounded corners. Also, the terms "first", "second", "third", etc. used in this specification are merely used to distinguish objects and do not rank the objects. In each drawing, an X-axis, a Y-axis, and a Z-axis orthogonal to each other are shown.

[0020] (Overall Configuration of Wire Harness 10) As shown in Figure 1, the wire harness 10 comprises a first shielded wire 11 and a group of wires 20. The group of wires 20 includes a second shielded wire 12 and a third shielded wire 13. The wire harness 10 includes a connection structure 10A to which the first shielded wire 11 and the group of wires 20 are connected. The second shielded wire 12 and the third shielded wire 13 are arranged, for example, adjacent to each other.

[0021] As shown in Figure 6, the wire harness 10 includes a core wire connection portion 30, a connection portion insulating coating 40, and an exposed portion 50. As shown in Figure 1, the wire harness 10 includes a connection shield member 60. As shown in Figures 1, 3, and 5, the wire harness 10 includes a holding member 70 and a support member 80.

[0022] The first shield wire 11, the second shield wire 12, and the third shield wire 13 are arranged, for example, so as to extend in opposite directions from the core wire connection portion 30. The first shield wire 11, the second shield wire 12, and the third shield wire 13 extend, for example, along the X-axis of the drawing. In this case, the Y-axis and Z-axis of the drawing are perpendicular to the longitudinal directions of the first shield wire 11, the second shield wire 12, and the third shield wire 13. The second shield wire 12 and the third shield wire 13 may be arranged so as to extend in a direction intersecting the first shield wire 11. Alternatively, the second shield wire 12 and the third shield wire 13 may be arranged parallel to each other, or so as to extend in a direction intersecting each other. The second shield wire 12 and the third shield wire 13 may be arranged so as to increase in distance from the first wire.

[0023] The wire harness 10 is installed, for example, in a vehicle. The wire harness 10 electrically connects three or more in-vehicle devices. The wire harness 10 constitutes, for example, part of an electrical circuit, particularly a high-voltage circuit. Examples of vehicles include hybrid vehicles and electric vehicles.

[0024] (Configuration of the first shielded wire 11, the second shielded wire 12, and the third shielded wire 13) As shown in Figures 2 and 3, the first shielded wire 11 comprises a first core wire 11a and a first inner insulating sheath 11b covering the first core wire 11a. The first shielded wire 11 comprises a first individual shield member 11c covering the first inner insulating sheath 11b and a first outer insulating sheath 11d covering the first individual shield member 11c.

[0025] As shown in Figures 4 and 5, the second shielded wire 12 comprises a second core wire 12a and a second inner insulating sheath 12b covering the second core wire 12a. The second shielded wire 12 comprises a second individual shielding member 12c covering the second inner insulating sheath 12b and a second outer insulating sheath 12d covering the second individual shielding member 12c. The third shielded wire 13 comprises a third core wire 13a and a third inner insulating sheath 13b covering the third core wire 13a. The third shielded wire 13 comprises a third individual shielding member 13c covering the third inner insulating sheath 13b and a third outer insulating sheath 13d covering the third individual shielding member 13c. The cross-sectional shape of the first shielded wire 11, the second shielded wire 12, and the third shielded wire 13 is, for example, circular.

[0026] The first core wire 11a, the second core wire 12a, and the third core wire 13a can be, for example, a stranded wire made by twisting together multiple metal strands, or a single core wire made of a single conductor. Examples of single core wires include a columnar conductor with a solid internal structure and a cylindrical conductor with a hollow internal structure. The core wires may be a combination of multiple types of core wires, such as stranded wires and single core wires. As the material for the core wires, for example, metal materials such as copper-based or aluminum-based materials can be used.

[0027] The first inner insulating coating 11b, the second inner insulating coating 12b, and the third inner insulating coating 13b each cover the outer circumference of the first core wire 11a, the second core wire 12a, and the third core wire 13a, respectively, around the entire circumference of the axis. The first inner insulating coating 11b, the second inner insulating coating 12b, and the third inner insulating coating 13b can be made of, for example, an insulating resin material.

[0028] The first individual shielding member 11c, the second individual shielding member 12c, and the third individual shielding member 13c shield electromagnetic waves radiated from the first core wire 11a, the second core wire 12a, and the third core wire 13a, respectively. The material of the first individual shielding member 11c, the second individual shielding member 12c, and the third individual shielding member 13c includes, for example, a conductive material such as a copper alloy or an aluminum alloy. The first individual shielding member 11c, the second individual shielding member 12c, and the third individual shielding member 13c may be, for example, a braided member in which strands are woven into a tubular shape, or a foil member. The drawing schematically shows the case where the first individual shielding member 11c, the second individual shielding member 12c, and the third individual shielding member 13c are braided members.

[0029] The first outer insulating coating 11d, the second outer insulating coating 12d, and the third outer insulating coating 13d each cover the outer circumference of the first individual shielding member 11c, the second individual shielding member 12c, and the third individual shielding member 13c, respectively, around the entire circumference of the axis. The first outer insulating coating 11d, the second outer insulating coating 12d, and the third outer insulating coating 13d can be made of, for example, an insulating resin material.

[0030] As shown in Figure 4, the wire group 20 has a first recess 20a and a second recess 20b that are recessed toward the space between the second shield wire 12 and the third shield wire 13. The first recess 20a and the second recess 20b open toward opposite sides. The inner surfaces of the first recess 20a and the second recess 20b are composed of the outer surface of the second outer insulating coating 12d and the outer surface of the third outer insulating coating 13d. The first recess 20a and the second recess 20b may or may not be in communication. That is, the second outer insulating coating 12d of the second shield wire 12 and the third outer insulating coating 13d of the third shield wire 13 may be spaced apart or in contact.

[0031] (Configuration of the core wire connection part 30 and the connection part insulating coating 40 in connection structure 10A) The core wire connection section 30 electrically connects the first core wire 11a of the first shield wire 11, the second core wire 12a of the second shield wire 12, and the third core wire 13a of the third shield wire 13. More specifically, the end of the first shield wire 11 has a connection section in which the first core wire 11a is exposed. The end of the second shield wire 12 has a connection section in which the second core wire 12a is exposed. The end of the third shield wire 13 has a connection section in which the third core wire 13a is exposed. The core wire connection section 30 is constructed by electrically connecting the respective connection sections of the first core wire 11a, the second core wire 12a, and the third core wire 13a, for example, by welding, crimping, etc. The core wire connection section 30 has, for example, a splice connection structure.

[0032] The connection part insulating cover 40 is positioned to cover the core wire connection part 30. The connection part insulating cover 40 can be made of, for example, an insulating resin material. The connection part insulating cover 40 can be made using, for example, heat shrink tubing, insulating tape, etc.

[0033] (Configuration of the exposed portion 50 in the connection structure 10A) As shown in Figures 2 and 3, the first shielded wire 11 has a first exposed portion 51a where the first individual shielding member 11c is exposed to the outside. As shown in Figures 4 and 5, the second shielded wire 12 has a second exposed portion 51b where the second individual shielding member 12c is exposed to the outside. The third shielded wire 13 has a third exposed portion 51c where the third individual shielding member 13c is exposed to the outside.

[0034] The first exposed portion 51a is folded back so as to overlap the outer surface of the first outer insulating coating 11d of the first shielded wire 11. The second exposed portion 51b is folded back so as to overlap the outer surface of the second outer insulating coating 12d of the second shielded wire 12. The third exposed portion 51c is folded back so as to overlap the outer surface of the third outer insulating coating 13d of the third shielded wire 13.

[0035] (Configuration of the connecting shield member 60) As shown in FIG. 1, the connection shield member 60 is arranged to cover the connection part insulation coating 40. The connection shield member 60 shields electromagnetic waves radiated from the core wire connection part 30. The connection shield member 60 electrically connects the first individual shield member 11c, the second individual shield member 12c, and the third individual shield member 13c. Examples of the material of the connection shield member 60 include conductive materials such as copper alloys and aluminum alloys. The connection shield member 60 may be, for example, a braided member in which strands made of a conductive material are braided into a cylindrical shape, or may be a foil member made of a conductive material. In the drawings, a braided member that is the connection shield member 60 is schematically shown.

[0036] As shown in FIG. 1, the connection shield member 60 has a connection shield main body part 61a that covers the core wire connection part 30, and a first shield connection part 61b that is electrically connected to the first individual shield member 11c. The connection shield member 60 has a second shield connection part 61c that is electrically connected to the second individual shield member 12c, and a third shield connection part 61d that is electrically connected to the third individual shield member 13c.

[0037] (Configuration of the holding member 70 and the support member 80 in the connection structure 10A) As shown in FIGS. 1 to 5, the holding member 70 includes a first holding member 71a and a second holding member 71b. The first holding member 71a holds the first shield connection part 61b of the connection shield member 60 in a state of being pressed against the first exposed part 51a. The second holding member 71b holds the second shield connection part 61c of the connection shield member 60 in a state of being pressed against the second exposed part 51b. Further, the second holding member 71b holds the third shield connection part 61d of the connection shield member 60 in a state of being pressed against the third exposed part 51c.

[0038] Examples of the retaining member 70 include adhesive tape, cable ties, and clamps. Examples of the material of the retaining member 70 include metal materials and resin materials. The retaining member 70 may be conductive or electrically insulating. From the viewpoint of increasing the holding force of the retaining member 70, it is preferable that the material of the retaining member 70 be a metal material. For example, a metal cable tie can be used as the retaining member 70.

[0039] As shown in Figures 2 to 5, the support member 80 includes a first support member 81a and a second support member 81b. As shown in Figures 2 and 3, the first support member 81a is positioned opposite the first holding member 71a. The first support member 81a supports the first exposed portion 51a of the first shielded wire 11. The first support member 81a is positioned between the first exposed portion 51a and the first outer insulating coating 11d.

[0040] The first support member 81a has a shape that surrounds the outer circumference of the first outer insulating coating 11d, for example. The first support member 81a is a ring member that surrounds the outer circumference of the first outer insulating coating 11d of the first shielded wire 11.

[0041] Examples of materials for the first support member 81a include metal materials and resin materials. The first support member 81a may be electrically conductive or electrically insulating. If the first support member 81a is electrically conductive, an conductive path can be secured using the first support member 81a. If the material of the first support member 81a is a metal material, the support force of the first support member 81a can be easily increased.

[0042] As shown in Figures 4 and 5, the second support member 81b is positioned opposite the second holding member 71b. The second support member 81b supports the second exposed portion 51b of the second shielded wire 12 and the third exposed portion 51c of the third shielded wire 13. The second support member 81b is positioned between the second exposed portion 51b and the second outer insulating coating 12d. The second support member 81b is positioned between the third exposed portion 51c and the third outer insulating coating 13d.

[0043] As shown in Figures 4 and 6, the second support member 81b has a first restricting portion 82a and a second restricting portion 82b that restrict the second exposed portion 51b and the third exposed portion 51c from entering between the second shielded wire 12 and the third shielded wire 13. The first restricting portion 82a restricts the second exposed portion 51b and the third exposed portion 51c from entering the first recess 20a in the wire group 20. The first restricting portion 82a can also restrict the connecting shield member 60 from entering the first recess 20a. The first restricting portion 82a is positioned to block the first recess 20a.

[0044] The second restricting portion 82b restricts the second exposed portion 51b and the third exposed portion 51c from entering the second recess 20b in the wire group 20. The second restricting portion 82b can also restrict the connecting shield member 60 from entering the second recess 20b. The second restricting portion 82b is positioned to block the second recess 20b.

[0045] If the second exposed portion 51b is made of a braided material, the first restricting portion 82a and the second restricting portion 82b restrict the strands of the braided material constituting the second exposed portion 51b from entering between the second shield wire 12 and the third shield wire 13. If the third exposed portion 51c is made of a braided material, the first restricting portion 82a and the second restricting portion 82b restrict the strands of the braided material constituting the third exposed portion 51c from entering between the third shield wire 13 and the third shield wire 13. If the connecting shield member 60 is made of a braided material, the first restricting portion 82a and the second restricting portion 82b can also restrict the strands of the braided material constituting the connecting shield member 60 from entering between the second shield wire 12 and the third shield wire 13.

[0046] Between the first restricting portion 82a and the second holding member 71b, and between the second restricting portion 82b and the second holding member 71b, for example, a laminated portion of the second exposed portion 51b and the connecting shield member 60 is arranged. Also, between the first restricting portion 82a and the second holding member 71b, and between the second restricting portion 82b and the second holding member 71b, for example, a laminated portion of the third exposed portion 51c and the connecting shield member 60 is arranged.

[0047] The shapes of the first restricting section 82a and the second restricting section 82b can be, for example, a flat plate shape, or a shape having a convex surface that protrudes outward toward the group of electric wires 20. The second support member 81b has a shape that encloses the second outer insulating coating 12d and the third outer insulating coating 13d together. The second support member 81b is, for example, a ring member that encloses the second outer insulating coating 12d and the third outer insulating coating 13d together.

[0048] Examples of materials for the second support member 81b include metal materials and resin materials. The second support member 81b may be electrically conductive or electrically insulating. If the second support member 81b is electrically conductive, a conductive path can be secured using the second support member 81b. If the material of the second support member 81b is a metal material, the support force of the second support member 81b can be easily increased.

[0049] The second support member 81b is made of, for example, a metal plate and has an overlapping portion 83 where the ends of the metal plate overlap. The first restricting portion 82a of the second support member 81b is formed by the overlapping portion 83 of the second support member 81b.

[0050] (Method for manufacturing wire harness 10) Next, a method for manufacturing the wire harness 10 will be described. The following manufacturing method is just one example, and for example, the order in which each component is attached can be changed as appropriate.

[0051] In the process shown in Figure 6, the core wire connection portion 30 is formed by electrically connecting the first core wire 11a, the second core wire 12a, and the third core wire 13a. Next, a connection portion insulating cover 40 is provided to cover the core wire connection portion 30. In this process, the second support member 81b is placed on the outer circumference of the second outer insulating cover 12d and the third outer insulating cover 13d. In this process, although not shown in the figure, the first support member 81a is placed on the outer circumference of the first outer insulating cover 11d.

[0052] In the process shown in Figure 7, the second exposed portion 51b of the second shield wire 12 is folded back so that it follows the outer circumference of the second support member 81b. In this process, the third exposed portion 51c of the third shield wire 13 is folded back so that it follows the outer circumference of the second support member 81b. In this process, although not shown in the figure, the first exposed portion 51a of the first shield wire 11 is folded back so that it follows the outer circumference of the first support member 81a.

[0053] In the process shown in Figure 8, the connection shield member 60 is positioned to cover the connection portion insulating coating 40. In this process, the connection shield member 60 is positioned to overlap the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c.

[0054] In the next step, the second retaining member 71b is attached to the outer circumference of the connecting shield member 60. This allows the second shield connection portion 61c of the connecting shield member 60 to be held in a state of being pressed against the second exposed portion 51b and the third exposed portion 51c. Also in this step, the first retaining member 71a is attached to the outer circumference of the connecting shield member 60. This allows the first shield connection portion 61b of the connecting shield member 60 to be held in a state of being pressed against the first exposed portion 51a of the first shielded wire 11.

[0055] Although not shown in the diagram, a protective member may be provided around the outer circumference of the connecting shield member 60 as needed. The protective member is provided so as to surround the connecting shield member 60. The protective member has properties such as waterproofing and electrical insulation. Examples of protective members include heat-shrinkable tubing and tape material.

[0056] (Operation and effects of this embodiment) The operation and effects of this embodiment will now be described. (1) The wire harness 10 comprises a first shielded wire 11, a group of wires 20, and a connection structure 10A to which the first shielded wire 11 and the group of wires 20 are connected. The group of wires 20 includes a second shielded wire 12 and a third shielded wire 13. The first shielded wire 11 comprises a first core wire 11a, a first inner insulating coating 11b covering the first core wire 11a, a first individual shielding member 11c covering the first inner insulating coating 11b, and a first outer insulating coating 11d covering the first individual shielding member 11c. The second shielded wire 12 and the third shielded wire 13 each also have a laminated structure similar to that of the first shielded wire 11. The connection structure 10A of the wire harness 10 includes a core wire connection portion 30, a connection portion insulating cover 40 covering the core wire connection portion 30, and exposed portions 50 of a first exposed portion 51a, a second exposed portion 51b, and a third exposed portion 51c. The connection structure 10A of the wire harness 10 includes a connection shield member 60 positioned to cover the connection portion insulating cover 40. The connection structure 10A of the wire harness 10 includes a first holding member 71a that holds the connection shield member 60 in a state where it is pressed against the first exposed portion 51a. The connection structure 10A of the wire harness 10 includes a second holding member 71b that holds the connection shield member 60 in a state where it is pressed against the second exposed portion 51b and the third exposed portion 51c, respectively.

[0057] The connection structure 10A of the wire harness 10 includes a second support member 81b positioned opposite the second holding member 71b. The second support member 81b supports the second exposed portion 51b and the third exposed portion 51c. The second support member 81b has a first restricting portion 82a and a second restricting portion 82b that restrict the second exposed portion 51b and the third exposed portion 51c from entering between the second shielded wire 12 and the third shielded wire 13.

[0058] This configuration prevents the second exposed portion 51b and the third exposed portion 51c, to which the connecting shield member 60 is pressed, from entering between the second shielded wire 12 and the third shielded wire 13. This makes it possible to improve the contact between the connecting shield member 60 and the second exposed portion 51b and the third exposed portion 51c between the second support member 81b and the second holding member 71b. In other words, it is possible to improve the contact between the connecting shield member 60 and the second individual shield member 12c of the second shielded wire 12 and the third individual shield member 13c of the third shielded wire 13 between the second support member 81b and the second holding member 71b. Therefore, it is possible to improve the reliability of the electrical connection between the connecting shield member 60 and the second individual shield member 12c and the third individual shield member 13c.

[0059] (2) The second support member 81b has a shape that encloses the second outer insulating coating 12d of the second shield wire 12 and the third outer insulating coating 13d of the third shield wire 13 together. In this case, for example, displacement of the second support member 81b can be easily suppressed. Also, for example, the second support member 81b can support the second exposed portion 51b and the third exposed portion 51c around the entire circumference of the wire group 20, so that the adhesion of the second exposed portion 51b and the third exposed portion 51c to the connecting shield member 60 can be further improved. As a result, the reliability of the electrical connection between the connecting shield member 60 and the second individual shield member 12c and the third individual shield member 13c can be further improved.

[0060] (3) The second support member 81b is preferably made of a metal plate. The second support member 81b is preferably made of an overlapping portion 83 where the ends of the metal plate overlap. In this case, the rigidity of the second support member 81b can be easily increased by the overlapping portion 83 of the second support member 81b. For this reason, the function of the second support member 81b having the first restricting portion 82a and the second restricting portion 82b can be easily improved.

[0061] (4) The overlapping portion 83 of the second support member 81b preferably constitutes the first restricting portion 82a of the second support member 81b. In this case, the rigidity of the first restricting portion 82a of the second support member 81b can be easily increased. Therefore, the function of the first restricting portion 82a can be easily improved.

[0062] (5) The second exposed portion 51b of the second shield wire 12 is folded back so as to overlap the outer surface of the second outer insulating coating 12d of the second shield wire 12. The third exposed portion 51c of the third shield wire 13 is folded back so as to overlap the outer surface of the third outer insulating coating 13d of the third shield wire 13. The second support member 81b is positioned between the second outer insulating coating 12d and the third outer insulating coating 13d and the second exposed portion 51b and the third exposed portion 51c. In this case, for example, the second support member 81b can be easily positioned.

[0063] (6) The second support member 81b is preferably conductive. In this case, a conductive path can be secured using the second support member 81b. This makes it possible to improve the conductivity between the connecting shield member 60 and the second individual shield member 12c and the third individual shield member 13c by using the second support member 81b.

[0064] (7) When the second individual shield member 12c and the third individual shield member 13c are braided members, for example, the first restricting portion 82a can restrict the strands of the braided member from entering between the first shield wire 11 and the second shield wire 12. In this way, even when a braided member that is easily able to enter between the first shield wire 11 and the second shield wire 12 is used, it is possible to improve the reliability of the electrical connection as described above.

[0065] (8) Preferably, the laminated portion of the second exposed portion 51b and the connecting shield member 60 is arranged between the first restricting portion 82a and the second restricting portion 82b and the second holding member 71b. In this case, the adhesion between the second individual shield member 12c and the connecting shield member 60 can be increased between the first restricting portion 82a and the second restricting portion 82b and the second holding member 71b.

[0066] Furthermore, it is preferable that the laminated portion of the third exposed portion 51c and the connecting shield member 60 be arranged between the first restricting portion 82a and the second restricting portion 82b and the second holding member 71b. In this case, the adhesion between the third individual shield member 13c and the connecting shield member 60 can be improved between the first restricting portion 82a and the second restricting portion 82b and the second holding member 71b.

[0067] (Example of change) The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0068] As shown in Figure 9, the wire group 20 of the wire harness 10 may include a fourth shielded wire 14 in addition to the second shielded wire 12 and the third shielded wire 13. The fourth shielded wire 14 also has a fourth core wire 14a, a fourth inner insulating sheath 14b, a fourth individual shielding member 14c, and a fourth outer insulating sheath 14d, similar to the third shielded wire 13. The fourth individual shielding member 14c has a fourth exposed portion 51d. The connecting shielding member 60 has a fourth shielding connection portion 61e that is electrically connected to the fourth individual shielding member 14c. In this wire group 20, the outer circumferences of the third shielded wire 13 and the fourth shielded wire 14 have a first recess 20a and a second recess 20b that are recessed toward the space between the third shielded wire 13 and the fourth shielded wire 14. Preferably, the second support member 81b has a first restricting portion 82a and a second restricting portion 82b that restrict the third exposed portion 51c and the fourth exposed portion 51d from entering between the third shield wire 13 and the fourth shield wire 14. In this case, it is possible to improve the contact between the connecting shield member 60 and the fourth exposed portion 51d between the second support member 81b and the second holding member 71b.

[0069] The wire group 20 of the wire harness 10 may include four or more shielded wires. The first restricting portion 82a of the second support member 81b does not necessarily have to be formed by an overlapping portion 83. Furthermore, the overlapping portion 83 of the second support member 81b can be omitted.

[0070] The number of second support members 81b may be one or more. For example, multiple support members may be provided along the length of the wire group 20. A laminated portion of the second exposed portion 51b and the connecting shield member 60 is located between the first regulating portion 82a and the second regulating portion 82b and the second holding member 71b. This laminated portion may be located in a portion other than the space between the first regulating portion 82a and the second regulating portion 82b and the second holding member 71b.

[0071] A laminated portion of the third exposed portion 51c and the connecting shield member 60 is arranged between the first regulating portion 82a and the second regulating portion 82b and the second holding member 71b. This laminated portion may be arranged in a portion other than the space between the first regulating portion 82a and the second regulating portion 82b and the second holding member 71b.

[0072] The shape of the second support member 81b is not limited to a shape that encloses the second outer insulating coating 12d and the third outer insulating coating 13d together. The second support member 81b can also be changed to a shape that has only one of the first restricting portion 82a and the second restricting portion 82b, for example.

[0073] The second exposed portion 51b is folded back so as to overlap the outer circumferential surface of the second outer insulating coating 12d of the second shielded wire 12. Similarly, the third exposed portion 51c is folded back so as to overlap the outer circumferential surface of the third outer insulating coating 13d of the third shielded wire 13. This configuration can be modified as follows: The second exposed portion 51b and the third exposed portion 51c may be arranged without being folded back, extending along the second inner insulating coating 12b and the third inner insulating coating 13b, respectively. In this case, the second support member 81b is positioned between the second inner insulating coating 12b and the second exposed portion 51b. Alternatively, the second support member 81b is positioned between the third inner insulating coating 13b and the third exposed portion 51c. Even in this case, the same effects as those described in section (1) above can be achieved. In this modified example, it is preferable that the second support member 81b has a shape that encloses the second inner insulating coating 12b and the third inner insulating coating 13b together. The second support member 81b is, for example, a ring member that surrounds the second inner insulating coating 12b and the third inner insulating coating 13b together.

[0074] The first support member 81a can also be omitted. The first support member 81a may or may not have an overlapping portion where the ends of the metal plates overlap.

[0075] The number of first support members 81a may be one or more. The first exposed portion 51a is folded back so as to overlap the outer circumferential surface of the first outer insulating coating 11d of the first shielded wire 11, but it may also be arranged to extend along the first inner insulating coating 11b without being folded back. In this case, the first support member 81a is arranged between the first inner insulating coating 11b of the first shielded wire 11 and the first exposed portion 51a.

[0076] The embodiments and modifications described above are illustrative in all respects, and the present invention is not limited to these examples. That is, the scope of the present invention is indicated by the claims, and all modifications within the meaning and scope equivalent to the claims are intended to be included.
