[0003] Japanese Patent Translation of PCT International Publication No. 2023-538729

[0004] In the wire harness as described above, a shield member is provided corresponding to a core wire connection portion where the core wire of the first shielded wire and the core wire of the second shielded wire are connected. In order to enhance the shielding performance of the shield member provided corresponding to the core wire connection portion and the shielding performance of the shield members of each shielded wire, it is necessary to electrically connect these shield members. A highly reliable configuration is required when electrically connecting the shield members of each of the first and second shielded wires and also electrically connecting these shield members and the shield member provided corresponding to the core wire connection portion.

[0005] An object of the present disclosure is to provide a wire harness capable of enhancing the reliability of electrical connection of shield members.

[0006] The wire harness of the present disclosure includes a first shielded wire, a second shielded wire, and a connection structure in which the first shielded wire and the second shielded wire are connected. The first and second shielded wires each include a core wire, an inner insulating coating covering the core wire, an individual shield member covering the inner insulating coating, and an outer insulating coating covering the individual shield member. The connection structure includes a core wire connection portion, a connection portion insulating coating covering the core wire connection portion, an exposed portion where each of the individual shield members is exposed, an individual shield member connection portion electrically connecting the exposed portion of the first shielded wire and the exposed portion of the second shielded wire, a connection shield member arranged to cover the connection portion insulating coating, and a holding member holding the connection shield member in a state of being pressed against the exposed portion.

[0007] The wire harness of this disclosure has the effect of improving the reliability of the electrical connections of the shielding members.

[0009] [Description of Embodiments of the Disclosure] Embodiments of the Disclosure will be described first by listing them. [1] The wire harness of the Disclosure comprises a first shielded wire, a second shielded wire, and a connection structure to which the first shielded wire and the second shielded wire are connected, wherein the first and second shielded wires each comprises a core wire, an inner insulating cover covering the core wire, an individual shielding member covering the inner insulating cover, and an outer insulating cover covering the individual shielding member, wherein the connection structure comprises a core wire connection portion, a connection portion insulating cover covering the core wire connection portion, an exposed portion where each of the individual shielding members is exposed, an individual shielding member connection portion electrically connecting the exposed portion of the first shielded wire and the exposed portion of the second shielded wire, a connection shielding member arranged to cover the connection portion insulating cover, and a holding member that holds the connection shielding member in a state pressed against the exposed portion.

[0010] With this configuration, each individual shielding member has an individual shielding member connection part that electrically connects the exposed portion of each individual shielding member of the first and second shielded wires, thereby increasing the reliability of the electrical connection. Furthermore, since the connecting shielding member is held in a state where it is pressed against the exposed portion by the holding member, the reliability of the electrical connection between the connecting shielding member and the individual shielding member can be increased.

[0011] [2] In the above [1], the individual shield member connection portion may be covered by the connecting shield member. With this configuration, for example, the individual shield member connection portion can be protected by the connecting shield member. Also, for example, the individual shield member connection portion can be integrated with the connection portion insulating coating by the connecting shield member, making it easier to handle the wire harness.

[0012] [3] In [1] above, the individual shield member connection portion may be positioned in a location not covered by the connecting shield member. With this configuration, for example, the state of the individual shield member connection portion can be easily checked. In addition, the degree of freedom in the arrangement of the individual shield member connection portion can be increased.

[0013] [4] In any one of [1] to [3] above, the first and second shield wires may be arranged such that the orientation of the tips of the core wires of the first and second shield wires are aligned. With this configuration, the exposed portions of each individual shield member can be arranged adjacent to each other, which simplifies the structure for holding the connecting shield member in a state where it is pressed against the exposed portion by the holding member.

[0014] [5] In any one of [1] to [4] above, the connecting shield member may have a bag-shaped member having an opening, and the holding member may surround the outer circumference of the bag-shaped member so as to close the opening of the bag-shaped member. With this configuration, for example, the configuration of the connecting shield member can be simplified. Also, for example, it becomes possible to easily increase the force with which each of the individual shield members presses the connecting shield member against the exposed portion.

[0015] [6] 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 to which the first shielded wire and the group of wires are connected, wherein each of the first, second and third shielded wires comprises a core wire, an inner insulating cover covering the core wire, an individual shield member covering the inner insulating cover, and an outer insulating cover covering the individual shield member, wherein the connection structure may comprise a core wire connection portion, a connection portion insulating cover covering the core wire connection portion, exposed portions where each of the individual shield members is exposed, an individual shield member connection portion electrically connecting the exposed portion of the first shielded wire, the exposed portion of the second shielded wire, and the exposed portion of the third shielded wire, a connecting shield member arranged to cover the connection portion insulating cover, and a holding member that holds the connecting shield member in a state pressed against the exposed portion. Thus, the connection structure of the wire harness may be a structure in which a first shielded wire is connected to a group of wires including a second shielded wire and a third shielded wire.

[0016] [Details of Embodiments of the Disclosure] Specific examples of the wire harnesses of the Disclosure are described below with reference to the drawings. In each drawing, some parts of the configuration may be exaggerated or simplified for the sake of explanation. Also, the dimensional ratios of each part may differ in each drawing. As used in this specification, "cylindrical" does not only refer to those with a continuous circumferential wall formed around the entire circumference, but also includes those formed by combining multiple parts, and those having notches or other cutouts in the circumferential direction, such as C-shapes or U-shapes. The shape of "cylindrical" includes, but is not limited to, circular, elliptical, and polygons with pointed or rounded corners. In addition, terms such as "first," "second," and "third" in this specification are used simply to distinguish objects and do not rank them. Each drawing shows the X, Y, and Z axes which are orthogonal to each other.

[0017] <First Embodiment> The first embodiment of the wire harness will be described below. (Overall configuration of the 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 comprises a connection structure 10A to which the first shielded wire 11 and the group of wires 20 are connected. The first shielded wire 11, the second shielded wire 12, and the third shielded wire 13 are arranged, for example, adjacent to each other.

[0018] As shown in Figures 1, 4, and 5, the wire harness 10 includes a core wire connection portion 30, a connection portion insulating coating 40, an exposed portion 50, and an individual shield member connection portion 52. As shown in Figure 1, the wire harness 10 includes a connection shield member 60 and a holding member 70.

[0019] The first shielded wire 11 and the second and third shielded wires 12 and 13 of the wire group 20 are arranged to extend in the same direction, for example, starting from the core wire connection portion 30. The first shielded wire 11, the second shielded wire 12, and the third shielded 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 shielded wire 11, the second shielded wire 12, and the third shielded wire 13.

[0020] 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.

[0021] (Configuration of the first shielded wire 11, the second shielded wire 12, and the third shielded wire 13) As shown in Figure 4, 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.

[0022] 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.

[0023] Examples of the first core wire 11a, the second core wire 12a, and the third core wire 13a include stranded wires made by twisting together multiple metal strands, and single-core wires made of a single conductor. Examples of single-core wires include columnar conductors with a solid internal structure and cylindrical conductors 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, metal materials such as copper-based and aluminum-based materials can be used.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] The first shield wire 11, the second shield wire 12, and the third shield wire 13 are arranged so that the direction of the tip of the first core wire 11a, the direction of the tip of the second core wire 12a, and the direction of the tip of the third core wire 13a are aligned. The first outer insulating sheath 11d of the first shield wire 11 and the second outer insulating sheath 12d of the second shield wire 12 may be spaced apart or in contact. The second outer insulating sheath 12d of the second shield wire 12 and the third outer insulating sheath 13d of the third shield wire 13 may be spaced apart or in contact. The third outer insulating sheath 13d of the third shield wire 13 and the first outer insulating sheath 11d of the first shield wire 11 may be spaced apart or in contact.

[0028] (Configuration of the core wire connection part 30 and the connection part insulating coating 40 in the connection structure 10A) As shown in Figures 3 and 4, the core wire connection part 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 part in which the first core wire 11a is exposed. The end of the second shield wire 12 has a connection part in which the second core wire 12a is exposed. The end of the third shield wire 13 has a connection part in which the third core wire 13a is exposed. The core wire connection part 30 is constructed so that the connection parts of the first core wire 11a, the second core wire 12a, and the third core wire 13a are electrically connected, for example, by welding, crimping, etc. The core wire connection part 30 has, for example, a splice connection structure.

[0029] 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.

[0030] (Configuration of the exposed portion 50 and the individual shield member connection portion 52 in the connection structure 10A) As shown in Figure 4, the first shielded wire 11 has a first exposed portion 51a in which the first individual shield member 11c is exposed to the outside. The second shielded wire 12 has a second exposed portion 51b in which the second individual shield member 12c is exposed to the outside. The third shielded wire 13 has a third exposed portion 51c in which the third individual shield member 13c is exposed to the outside.

[0031] The individual shield member connection portion 52 electrically connects the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c. More specifically, the individual shield member connection portion 52 is constructed by electrically connecting the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c, for example, by welding, crimping, or the like.

[0032] (Configuration of the connection shielding member 60) As shown in Figures 1 and 3, the connection shielding member 60 is positioned to cover the connection portion insulating coating 40. The connection shielding member 60 shields electromagnetic waves radiated from the core wire connection portion 30. The individual shielding member connection portion 52 is covered by the connection shielding member 60.

[0033] As shown in Figures 1 and 2, the connecting shield member 60 is electrically connected to the first exposed portion 51a of the first individual shield member 11c, the second exposed portion 51b of the second individual shield member 12c, and the third exposed portion 51c of the third individual shield member 13c. More specifically, the connecting shield member 60 has a hollow structure that covers the connecting portion insulating coating 40 and a shielding connection portion that electrically connects the hollow structure to the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c.

[0034] The connecting shield member 60 has, for example, a bag-shaped member 61 having an opening 61a. The opening 61a of the bag-shaped member 61 is sized to allow the connecting portion insulating coating 40 to be inserted. The opening 61a of the bag-shaped member 61 is also sized to allow the individual shield member connecting portion 52 to be inserted.

[0035] The material of the connecting shield member 60 may be a conductive material such as a copper alloy or an aluminum alloy. The connecting shield member 60 may be a braided member in which strands made of a conductive material are woven together, or it may be a foil member made of a conductive material. The drawing schematically shows a braided member which is the connecting shield member 60.

[0036] (Configuration of the holding member 70 in the connection structure 10A) As shown in Figures 1 and 2, the holding member 70 holds the connection shield member 60 in a state where it is pressed against the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c. The holding member 70 is provided on the outer circumference of the overlapping portion between the exposed portion 50 and the connection shield member 60. For example, if the connection shield member 60 has a bag-shaped member 61, the holding member 70 surrounds the outer circumference of the bag-shaped member 61 so as to close the opening 61a of the bag-shaped member 61.

[0037] 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.

[0038] (Method for manufacturing the 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.

[0039] In the process shown in Figure 4, 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. In addition, the individual shield member connection portion 52 is formed by electrically connecting the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c.

[0040] In the process shown in Figure 5, a connection insulation cover 40 is provided so as to cover the core wire connection portion 30. Next, in the process shown in Figures 5 and 6, a connection shield member 60 is positioned so as to cover the connection insulation cover 40. For example, if the connection shield member 60 has a bag-shaped member 61, the connection insulation cover 40 is inserted into the bag-shaped member 61 through the opening 61a of the bag-shaped member 61. The connection insulation cover 40 is also inserted into the bag-shaped member 61 through the opening 61a of the connection shield member 60. At this time, the end of the bag-shaped member 61 on the opening 61a side is positioned so as to overlap the exposed portion 50.

[0041] In the next step, the retaining member 70 is attached to the outer circumference of the connecting shield member 60. For example, if the connecting shield member 60 has a bag-shaped member 61, the retaining member 70 is attached to the end on the side of the opening 61a of the bag-shaped member 61 so as to close the opening 61a. This allows the connecting shield member 60 to be held in a state pressed against the exposed portion 50.

[0042] Although illustration is omitted, a protective member for protecting the connection shield member 60 can be provided on the outer periphery of the connection shield member 60 as needed. The protective member is provided so as to surround the connection shield member 60. The protective member has properties such as waterproofness and electrical insulation, for example. Examples of the protective member include a heat-shrinkable tube, a tape material, a molded resin, and the like.

[0043] (Operations and Effects of the Present Embodiment) The operations and effects of the present embodiment will be described. (1-1) The wire harness 10 includes a first shielded wire 11, a wire group 20, and a connection structure 10A in which the first shielded wire 11 and the wire group 20 are connected. The wire group 20 includes a second shielded wire 12 and a third shielded wire 13. The first shielded wire 11 includes a first core wire 11a, a first inner insulation coating 11b that covers the first core wire 11a, a first individual shield member 11c that covers the first inner insulation coating 11b, and a first outer insulation coating 11d that covers the first individual shield member 11c. Each of the second shielded wire 12 and the third shielded wire 13 has the same laminated structure as the first shielded wire 11.

[0044] The connection structure 10A of the wire harness 10 includes a core wire connection portion 30, a connection portion insulation coating 40 that covers the core wire connection portion 30, a first exposed portion 51a, and an exposed portion 50. The connection structure 10A includes an individual shield member connection portion 52 that electrically connects the exposed portions 50, a connection shield member 60 that is disposed so as to cover the connection portion insulation coating 40, and a holding member 70 that holds the connection shield member 60 in a state of being pressed against the exposed portion 50.

[0045] According to this configuration, since the individual shield member connection portion 52 that electrically connects the exposed portions 50 is provided, it is possible to enhance the reliability of the electrical connection in the first individual shield member 11c, the second individual shield member 12c, and the third individual shield member 13c. Further, the connection shield member 60 is held in a state of being pressed against the exposed portion 50 by the holding member 70. Therefore, it is possible to enhance the reliability of the electrical connection between the connection shield member 60 and the first individual shield member 11c, the second individual shield member 12c, and the third individual shield member 13c.

[0046] (1-2) The individual shield member connection portion 52 is covered by the connection shield member 60. In this case, for example, it becomes possible to protect the individual shield member connection portion 52 by the connection shield member 60. Also, for example, since the individual shield member connection portion 52 can be integrated with the connection portion insulation coating 40 by the connection shield member 60, the handling of the wire harness 10 becomes easy.

[0047] (1-3) The first shielded wire 11, the second shielded wire 12, and the third shielded wire 13 are arranged such that the directions of the tips of the first core wire 11a, the second core wire 12a, and the third core wire 13a are aligned. In this case, since the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c can be arranged adjacent to each other, it becomes possible to simplify the structure for holding the connection shield member 60 pressed against the exposed portion 50 by the holding member 70.

[0048] (1-4) The connection shield member 60 may have a bag-shaped member 61 having an opening 61a. At this time, the holding member 70 may surround the outer periphery of the bag-shaped member 61 so as to close the opening 61a of the bag-shaped member 61. In this case, for example, the configuration of the connection shield member 60 can be simplified. Also, for example, it becomes possible to easily increase the force for pressing the connection shield member 60 against the exposed portion 50.

[0049] <Second Embodiment> Hereinafter, a second embodiment of the wire harness 10 will be described. In the second embodiment, the same components as those in the first embodiment or corresponding components are denoted by the same reference numerals, and part or all of the description of the components may be omitted.

[0050] (Overall Configuration of Wire Harness 10) As shown in FIG. 7, the individual shield member connection portion 52 of the wire harness 10 in the present embodiment is arranged at a position not covered by the connection shield member 60.

[0051] (Configuration of the exposed portion 50 and the individual shield member connection portion 52 in the connection structure 10A) As shown in Figures 8 and 9, 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 shield wire 11. 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 shield wire 12. 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 shield wire 13.

[0052] As shown in Figure 9, the individual shield member connection portion 52 electrically connects the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c that have been folded back as described above. (Method of manufacturing the wire harness 10) As shown in Figures 8 and 9, the individual shield member connection portion 52 is formed by folding back the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c, and then electrically connecting the first exposed portion 51a, the second exposed portion 51b, and the third exposed portion 51c.

[0053] As shown in Figure 9, the connecting shield member 60 is positioned to cover the insulating coating 40 of the connection portion. At this time, the individual shield member connection portion 52 is positioned so as not to be covered by the connecting shield member 60. Next, the holding member 70 is attached to the outer circumference of the connecting shield member 60. This allows the connecting shield member 60 to be held in a state pressed against the exposed portion 50.

[0054] (Operation and Effects of this Embodiment) The operation and effects of this embodiment will now be described. (2-1) The individual shield member connection portion 52 is positioned in a location that is not covered by the connecting shield member 60. In this case, for example, the state of the individual shield member connection portion 52 can be easily checked. In addition, the degree of freedom in the arrangement of the individual shield member connection portion 52 can be increased.

The above embodiments and the following examples of modifications can be combined with each other to the extent that they do not contradict each other technically.

[0056] The wire harness 10 may include a fourth shield wire in addition to the second shield wire 12 and the third shield wire 13. The core wire of the fourth shield wire can also be connected to the core wire connection part 30. Furthermore, the exposed portion of the individual shield member of the fourth shield wire can be connected to the individual shield member connection part 52.

[0058] - The bag-shaped member 61 described above is not limited to one in which strands are woven into a bag shape. The bag-shaped member 61 may be, for example, constructed by closing one of the openings at both ends of a cylindrical member with a separately prepared fastening member.

[0059] The connecting shield member 60 is not limited to a bag-shaped member 61, but may be, for example, a cylindrical member having openings at both ends. In this cylindrical member, the first opening is closed by the holding member 70, while the second opening is open.

[0060] - The insulating coating 40 of the connection portion may be in contact with the connecting shield member 60 or may be separated from it. - The connecting shield member 60 may be in contact with the first outer insulating coating 11d, the second outer insulating coating 12d, and the third outer insulating coating 13d or may be separated from it.

[0061] - The individual shield member connection portion 52 may be in contact with the connecting shield member 60 or may be spaced apart. - The number of holding members 70 may be one or more.

[0062] The first shielded wire 11, the second shielded wire 12, and the third shielded wire 13 are arranged so that the direction of the tip of the first core wire 11a, the direction of the tip of the second core wire 12a, and the direction of the tip of the third core wire 13a are aligned. The arrangement is not limited to this, and for example, the first shielded wire 11 and the second shielded wire 12 may be arranged so that the direction of the tip of the first core wire 11a and the direction of the tip of the second core wire 12a are opposite.
