[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 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 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, a connection shield member disposed so as to cover the connection portion insulating coating, a holding member that holds the exposed portion and the connection shield member, and a conductive member disposed to face the holding member. The conductive member includes at least one of a first conductive member provided corresponding to the first shielded wire and a second conductive member provided corresponding to the second shielded wire. The holding member is provided so as to press the exposed portion in contact with the conductive member and the connection shield member in contact with the conductive member against the conductive member respectively.

[0010] According to this configuration, the holding member provided as described above can enhance both the adhesion of the exposed portion to the conductive member and the adhesion of the connection shield member to the conductive member. Since the conductive member serves as a conductive path between the exposed portion and the connection shield member, it is possible to enhance the reliability of the electrical connection between the individual shield member and the connection shield member of the shielded wire.

[0011] [2] In the above [1], the holding member may include an individual shield holding member that presses the exposed portion against the conductive member and a connection shield holding member that is disposed adjacent to the individual shield holding member and presses the connection shield member against the conductive member.

[0012] According to this configuration, the exposed portion and the connection shield member can be pressed against the conductive member by the individual shield holding member and the connection shield holding member, respectively. Thereby, the adhesion of the exposed portion to the conductive member and the adhesion of the connection shield member to the conductive member can be independently enhanced. Thereby, it becomes possible to further enhance the reliability of the electrical connection between the exposed portion and the conductive member and the reliability of the electrical connection between the connection shield member and the conductive member.

[0013] [3] In [2] above, the connection shield member is disposed so as to cover at least one of the exposed portions of the first shielded wire and the exposed portion of the second shielded wire, and the individual shield holding member may be provided so as to press the exposed portion covered by the connection shield member against the conductive member. According to this configuration, for example, it becomes possible to protect at least one of the exposed portions and the individual shield holding member by the connection shield member.

[0014] [4] In [1] or [2] above, the conductive member includes a first conductive member provided corresponding to the first shielded wire and a second conductive member provided corresponding to the second shielded wire, and the connection shield member may not cover the exposed portion of the first shielded wire and the exposed portion of the second shielded wire. According to this configuration, for example, by reducing the size of the connection shield member, it becomes possible to reduce the material of the connection shield member.

[0015] [5] In any one of [1] to [4] above, the connection shield member is a foil member, and the holding member may be provided so as to press the foil member in surface contact with the conductive member against the conductive member. According to this configuration, it becomes possible to ensure a wide contact area between the foil member, which is the connection shield member, and the conductive member. Therefore, the reliability of the electrical connection between the connection shield member and the conductive member can be enhanced.

[0016] [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 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 an arrangement that covers the connection portion insulating cover. The wire harness connection structure comprises a connecting shield member, a holding member for holding the connecting shield member and the exposed portion, and a conductive member positioned opposite the holding member, wherein the conductive member includes at least one conductive member selected from a first conductive member provided corresponding to the first shield wire, a second conductive member provided corresponding to the second shield wire, and a third conductive member provided corresponding to the third shield wire, and the holding member may be provided so as to press the exposed portion in contact with the conductive member and the connecting shield member in contact with the conductive member against the conductive member, respectively. Thus, the wire harness connection structure may be a structure in which a first shield wire and a group of wires including a second shield wire and a third shield wire are connected.

[0017] [Details of the embodiments of this disclosure] Specific examples of the wire harnesses of this 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. In this specification, "orthogonal" and "parallel" include not only cases where they are strictly orthogonal or parallel, but also cases where they are approximately orthogonal or parallel within the range that achieves the effects of this embodiment. As used in this description, "cylindrical" includes not only those in which a circumferential wall is formed continuously around the entire circumference, but also those formed by combining multiple parts to form a cylinder, and those having notches in part of 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.

[0059] In the process shown in Figure 10, the connecting shield member 60 is positioned to cover the connecting portion insulating coating 40. In this process, the first shield connecting portion 61b of the connecting shield member 60 is positioned to overlap the first conductive member 81. The second shield connecting portion 61c of the connecting shield member 60 is positioned to overlap the second conductive member 82.

The connection structure 10A also includes a holding member 70 that holds the exposed portion 50 and the connection shield member 60, and a conductive member 80 positioned opposite the holding member 70.

[0063] The holding member 70 is provided such that the exposed portion 50 that contacts the conductive member 80 and the connecting shield member 60 that contacts the conductive member 80 are pressed against the conductive member 80. With this configuration, the retaining member 70 provided as described above makes it possible to improve both the adhesion of the exposed portion 50 to the conductive member 80 and the adhesion of the connecting shield member 60 to the conductive member 80. Since the conductive member 80 forms a conductive path between the exposed portion 50 and the connecting shield member 60, it is possible to improve the reliability of the electrical connection between, for example, the first individual shield member 11c of the first shielded wire 11 and the connecting shield member 60.

[0064] (1-2) The retaining member 70 includes, for example, a first individual shield retaining member 71A and a first connecting shield retaining member 71B arranged adjacent to the first individual shield retaining member 71A. With this configuration, for example, the first exposed portion 51 and the connecting shield member 60 can be pressed against the first conductive member 81 by the first individual shield retaining member 71A and the first connecting shield retaining member 71B, respectively. This makes it possible to independently improve the adhesion of the first exposed portion 51 to the first conductive member 81 and the adhesion of the connecting shield member 60 to the first conductive member 81. Accordingly, it is possible to further improve the reliability of the electrical connection between the first exposed portion 51 and the first conductive member 81 and the reliability of the electrical connection between the connecting shield member 60 and the first conductive member 81.

[0065] Furthermore, the retaining member 70 includes a second individual shield retaining member 72A and a common connecting shield retaining member 74B arranged adjacent to the second individual shield retaining member 72A. This makes it possible to further improve the reliability of the electrical connection between the second exposed portion 52 and the second conductive member 82, and the reliability of the electrical connection between the connecting shield member 60 and the second conductive member 82.

[0066] Furthermore, the retaining member 70 includes a third individual shield retaining member 73A and a common connecting shield retaining member 74B arranged adjacent to the third individual shield retaining member 73A. This makes it possible to further improve the reliability of the electrical connection between the third exposed portion 53 and the third conductive member 83, and the reliability of the electrical connection between the connecting shield member 60 and the third conductive member 83.

[0067] (1-3) The connecting shield member 60 is positioned, for example, to cover the first exposed portion 51. The first individual shield holding member 71A is provided to press the first exposed portion 51, which is covered by the connecting shield member 60, against the first conductive member 81. In this case, for example, the first exposed portion 51 and the first individual shield holding member 71A can be protected by the connecting shield member 60.

[0068] (1-4) When the connecting shield member 60 is a foil member, it is preferable that the holding member 70 is provided so as to press the foil member, which is in surface contact with the conductive member 80, against the conductive member 80. This makes it possible to secure a large contact area between the foil member which is the connecting shield member 60 and the conductive member 80. This makes it possible to improve the reliability of the electrical connection between the connecting shield member 60 and the conductive member 80.

[0069] <Second Embodiment> The following describes a second embodiment of the wire harness 10. In the second embodiment, the same reference numerals are used for the same or corresponding components as in the first embodiment, and some or all of the description of those components may be omitted.

[0070] (Overall configuration of wire harness 10) As shown in Figure 11, the connecting shield member 60 in the wire harness 10 of this embodiment does not cover the exposed portion 50. The connecting shield member 60 does not cover the first individual shield retaining member 71A and the common individual shield retaining member 75A. The common individual shield retaining member 75A is configured by combining the second individual shield retaining member 72A and the third individual shield retaining member 73A of the first embodiment as a common retaining member 70.

[0071] (Configuration of connection structure 10A) As shown in Figures 12 and 14, the first exposed portion 51 is not folded back to overlap the outer surface of the first outer insulating coating 11d of the first shielded wire 11, but is positioned to extend along the outer surface of the first inner insulating coating 11b. As shown in Figures 15 and 17, the second exposed portion 52 is not folded back to overlap the outer surface of the second outer insulating coating 12d of the second shielded wire 12, but is positioned to extend along the outer surface of the second inner insulating coating 12b. As shown in Figure 15, the third exposed portion 53 is not folded back to overlap the outer surface of the third outer insulating coating 13d of the third shielded wire 13, but is positioned to extend along the outer surface of the third inner insulating coating 13b.

[0072] As shown in Figure 11, the connecting shield member 60 is positioned between the first individual shield holding member 71A and the common individual shield holding member 75A in the direction along the X-axis. The first connecting shield holding member 71B and the common connecting shield holding member 74B are positioned between the first individual shield holding member 71A and the common individual shield holding member 75A in the direction along the X-axis.

[0073] As shown in Figures 12 to 17, the holding member 70 is provided such that the exposed portion 50 that contacts the conductive member 80 and the connecting shield member 60 that contacts the conductive member 80 are pressed against the conductive member 80.

[0074] (Operation and effects of this embodiment) The operation and effects of this embodiment will now be described. (2-1) The connecting shield member 60 does not cover the first exposed portion 51 and the second exposed portion 52. In this case, for example, by reducing the dimensions of the connecting shield member 60, it is possible to reduce the amount of material used for the connecting shield member 60.

[0075] (2-2) The wire harness 10 of the second embodiment can also obtain the same effects and advantages as (1-1), (1-2), and (1-4) of the first embodiment. (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.

[0076] The wire harness 10 may include a fourth shielded wire in addition to the second shielded wire 12 and the third shielded wire 13. It is preferable to apply the same connection structure as in the above embodiment to the fourth shielded wire as well.

[0077] The wire harness 10 may have four or more shielded wires in its wire group 20. The connection structure 10A of the wire harness 10 may be a connection structure between two shielded wires, namely the first shielded wire 11 and the second shielded wire 12.

[0078] The retaining member 70, which is provided to press the exposed portion 50 that contacts the conductive member 80 and the connecting shield member 60 that contacts the conductive member 80 against the conductive member 80, can be provided corresponding to at least one exposed portion 50.

[0079] For example, the first conductive member 81 can be omitted, and the first exposed portion 51 and the connecting shield member 60 can be held together using a holding member that holds the connecting shield member 60 in contact with the first exposed portion 51.

[0080] Alternatively, for example, the second conductive member 82 can be omitted, and the second exposed portion 52 and the connecting shield member 60 can be held together using a holding member that holds the connecting shield member 60 in contact with the second exposed portion 52.

[0081] Furthermore, for example, the third conductive member 83 can be omitted, and the third exposed portion 53 and the connecting shield member 60 can be held together using a holding member that holds the connecting shield member 60 in contact with the third exposed portion 53.

[0082] In the first embodiment, the second conductive member 82 and the third conductive member 83 may be composed of a single conductive member 80 that collectively surrounds the second outer insulating coating 12d and the third outer insulating coating 13d.

[0083] In the second embodiment, the second conductive member 82 and the third conductive member 83 may be composed of a single conductive member 80 that collectively surrounds the second inner insulating coating 12b and the third inner insulating coating 13b.

[0084] The number of first individual shield retaining members 71A may be one or more. The number of first connecting shield retaining members 71B may be one or more. The number of second individual shield retaining members 72A may be one or more. The number of third individual shield retaining members 73A may be one or more. The number of common connecting shield retaining members 74B may be one or more. The number of common individual shield retaining members 75A may be one or more.

[0085] In the second embodiment, the first individual shield holding member 71A and the first connecting shield holding member 71B can also be constructed from a single holding member 70. In the second embodiment, the common individual shield holding member 75A and the common connecting shield holding member 74B can also be constructed from a single holding member 70.

[0086] 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.
