[Description of embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
The wire harness of the present disclosure includes:
[1] A plurality of shielded electric wires each having a core wire and an electromagnetic shielding member that covers the outer periphery of the core wire, a first connection portion where the core wires for a first potential are connected to each other, and the core wires for a second potential are connected to each other. a second connection part to which is connected; and an insulating member interposed between the first connection part and the second connection part and covering the outer periphery of the first connection part and the second connection part. and at least one of the plurality of shielded wires is a multi-core collectively shielded wire having a plurality of core wires and the electromagnetic shielding member that collectively covers the plurality of core wires, and each of the plurality of shielded wires is The electromagnetic shielding members are connected to each other outside the insulating member.

According to the same configuration, the first connection part and the second connection part are covered with the insulating member, and all the electromagnetic shielding members are connected outside the insulating member, so that from the periphery of the first connection part and the second connection part Emission of electromagnetic waves is suppressed. The structure is simpler than a structure in which the outer peripheries of the first connection part and the second connection part are each covered with separate electromagnetic shielding members. Moreover, since at least one of the plurality of shielded wires is a multicore collectively shielded wire, the configuration is simpler than when all the shielded wires are each core shielded wire. That is, if all of the plurality of shielded wires are core shielded wires, the number of electromagnetic shielding members increases, but in this configuration, a plurality of electromagnetic shielding members are grouped together.

[2] In the above [1], all of the plurality of shielded wires may be the multicore collectively shielded wires.
According to this configuration, the configuration is simpler than the case where at least one of the plurality of shielded wires is each core shielded wire having one electromagnetic shielding member for one core wire.

[3] In the above [1] or [2], each of the plurality of connection parts includes a plurality of connection parts to which the core wires are connected, including the first connection part and the second connection part. The cross-sectional shape perpendicular to the extending direction of the core wire may be flat, and the cross-sectional shapes may be stacked in a thinner direction.

According to this configuration, the wire harness can be made into a more compact shape compared to another configuration in which the plurality of connection parts are arranged in a direction different from the present configuration.
[4] In the above [3], the number of core wires in the multi-core collectively shielded electric wire may match the number of the plurality of stacked connection parts.

According to this configuration, all of the plurality of core wires in the multicore collectively shielded electric wire are stacked, so that the wire harness can be made into a compact shape.
[5] In any one of [1] to [4] above, the insulating member may be configured to be disposed from outside of the first connection portion and the second connection portion.

According to this configuration, it is not necessary to assemble the insulating member in advance before connecting the core wires in the first connection part and the second connection part, so that the assemblability becomes good.
[6] Any one of [1] to [5] above, including a shield connecting member to which each of the electromagnetic shielding members in the plurality of shielded wires is connected while covering the outer periphery of the insulating member. Good too.

According to the configuration, since the first connecting part and the second connecting part are covered by the shield connecting member via the insulating member and the electromagnetic shielding member is connected to the shield connecting member, the first connecting part and the second connecting part Emission of electromagnetic waves from the surrounding area can be effectively suppressed. In addition, since the first connection part and the second connection part are covered together by a single shield connection member, compared to a structure in which the first connection part and the second connection part are each covered by separate shield connection members, , has a simple configuration.

[7] In the above [6], the shield connecting member may be configured to be disposed from outside the insulating member.
According to this structure, unlike a pipe formed in a cylindrical shape, it is not necessary to pass the shield wire through the shield connecting member in advance, so that ease of assembly is improved.

[8] In the above [6] or [7], a fixing member may be provided that fixes the shield connecting member and each of the electromagnetic shield members in the plurality of shielded wires.

According to this configuration, the shield connecting member and the electromagnetic shielding member can be easily connected without performing complicated welding work or the like.
[9] In [8] above, the fixing member may be a caulking member that is provided so as to surround the shield connecting member and the electromagnetic shielding member and fixed by caulking while using the shield connecting member as a base. good.

According to the configuration, the shield connecting member and the electromagnetic shielding member can be easily connected by caulking and fixing.
[10] In any one of [1] to [9] above, the insulating member includes a first insulating member that covers the outer periphery of the first connecting portion, and a second insulating member that covers the outer periphery of the second connecting portion. and an insulating member.

According to the configuration, by providing the first insulating member in the first connecting portion and providing the second insulating member in the second connecting portion, the second insulating member is provided between the first connecting portion and the second connecting portion. Insulation can be easily ensured by using an insulating member that covers the outer periphery of the first connection part and the second connection part.

[11] Any one of [1] to [10] above, including a waterproof member that collectively covers the first connection portion, the second connection portion, the insulating member, and the electromagnetic shielding member. Good too.

According to this configuration, the first connection part, the second connection part, and the electromagnetic shielding member can be prevented from being exposed to water all at once using a single waterproof member.
[12] In the above [11], the multicore collectively shielded electric wire may have a spacer member that fills a gap inside the wire corresponding to a portion where the waterproof member is provided.

According to the same configuration, the spacer member prevents the outer surface of the multi-core collectively shielded wire from bending inward at the portion where the waterproof member is provided. Therefore, it is possible to prevent a gap from forming between the outer surface of the multi-core collectively shielded electric wire and the waterproof member, thereby preventing liquid from entering inside the waterproof member.

[13] In any one of [1] to [10] above, the connection portion waterproof member covers the first connection portion and the second connection portion, and the electromagnetic shielding member may be exposed. good.

According to the same configuration, the first connection part and the second connection part can be prevented from being exposed to water by the connection part waterproof member. Further, compared to a configuration including a waterproof member that collectively covers the first connecting portion, the second connecting portion, and the electromagnetic shielding member, the size can be reduced, for example.

[14] In the above [13], the connection portion waterproof member may also serve as the insulating member.
According to this configuration, the configuration can be simplified compared to a case where the connecting portion waterproof member is provided separately and independently from the insulating member.

[15] In the above [14], the connection portion waterproof member may be a non-conductive molded resin.
According to the same structure, it is possible to easily provide a connecting portion waterproof member that also serves as an insulating member.

[16] In any one of [13] to [15] above, the connection portion waterproof member includes a first waterproof member that covers the first connection portion and a second waterproof member that covers the second connection portion. It may be composed of.

According to the configuration, by providing the first waterproof member in the first connecting portion and providing the second waterproof member in the second connecting portion, the first waterproof member is provided between the first connecting portion and the second connecting portion. Insulation can be easily ensured by the connection part waterproof member that covers the outer periphery of the first connection part and the second connection part.

[17] Any one of [13] to [16] above, comprising a shield connecting member to which each of the electromagnetic shielding members in the plurality of shielded wires is connected while covering the outer periphery of the insulating member, The shield connecting member may be configured to be disposed from outside the insulating member, and the connecting portion waterproof member may be interposed between the first connecting portion and the second connecting portion and the shield connecting member. good.

According to the configuration, since the first connecting part and the second connecting part are covered by the shield connecting member via the insulating member and the electromagnetic shielding member is connected to the shield connecting member, the first connecting part and the second connecting part Emission of electromagnetic waves from the surrounding area can be effectively suppressed. In addition, in the same configuration, the first connection part and the second connection part are covered together by a single shield connecting member, so for example, the first connection part and the second connection part are each covered by separate shields. The structure is simpler than the structure covered by the connecting member. In addition, the shield connecting member configured to be disposed from the outside of the insulating member is easy to assemble because there is no need to pass a shield wire through it in advance, as is the case with, for example, a cylindrical pipe. Further, since the connecting portion waterproof member is not disposed outside the shield connecting member, it does not interfere with the connection between the shield connecting member and the electromagnetic shielding member.

Thereby, the first electromagnetic shielding member 26 , the second electromagnetic shielding member 36 , and the third electromagnetic shielding member 46 are connected to each other outside the insulating member 51 .

Further, the wire harness 11 includes a caulking member 53 as a fixing member that fixes the shield connecting member 52, the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46.

(Configuration of caulking member 53)
The caulking member 53 is made of, for example, a conductive metal ring made of aluminum alloy or the like. The length of the caulking member 53 along the extending direction of the wire harness 11 is set to be shorter than the length of the shield connecting member 52. Two caulking members 53 are provided. One caulking member 53 is provided so as to surround the shield connecting member 52 and the first electromagnetic shielding member 26 while using the shield connecting member 52 as a base, and is caulked and fixed thereto. The other caulking member 53 is provided so as to surround the shield connecting member 52, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46, and is caulked and fixed using the shield connecting member 52 as a base.

Further, as shown in FIGS. 1 and 2, the wire harness 11 includes a waterproof member 54.
(Configuration of waterproof member 54)
The waterproof member 54 includes the first connecting portion 16, the second connecting portion 17, the insulating member 51, the shield connecting member 52, the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, the third electromagnetic shielding member 46, etc. cover. The waterproof member 54 of this embodiment is molded resin.

As shown in FIG. 7, the waterproof member 54 is molded by filling an area surrounded by a mold 55 disposed outside the shield connecting member 52 and the like with a molten resin material. Note that the

outer insulation coatings

27, 37, and 47 accommodated in the mold 55 are coated with an adhesive 56 in advance, so that the

outer insulation coatings

27, 37, and 47 and the waterproof member 54 are bonded without any gaps. has been done. Further, the molten resin material enters the shield connecting member 52 until it reaches the first connecting portion 16, the second connecting portion 17, etc. arranged inside the shield connecting member 52, and then hardens to cover the shield connecting member 52.

Moreover, as shown in FIGS. 2 and 4, each of the first multi-core collectively shielded electric wire 21, the second multi-core collectively shielded electric wire 31, and the third multi-core collectively shielded electric wire 41 is connected to a portion where the waterproof member 54 is provided. A spacer member 57 is provided in the corresponding interior to fill the void. Specifically, in a configuration in which the spacer member 57 is not provided inside the outer insulation coating 27, the first multi-core collectively shielded electric wire 21 has an air gap between the

inner insulation coatings

23, 25 and the first electromagnetic shielding member 26. However, a spacer member 57 is provided in the gap. Further, in the second multi-core collectively shielded electric wire 31, in a configuration in which the spacer member 57 is not provided inside the outer insulation sheath 37, there is a gap between the

inner insulation sheaths

33, 35 and the second electromagnetic shielding member 36. However, a spacer member 57 is provided in the gap. Further, in the third multi-core collectively shielded electric wire 41, in a configuration in which the spacer member 57 is not provided inside the outer insulation coating 47, there is a gap between the

inner insulation coatings

43, 45 and the third electromagnetic shielding member 46. However, a spacer member 57 is provided in the gap. As a result, the

outer insulation coatings

27, 37, and 47 of the first multicore collectively shielded wire 21, the second multicore collectively shielded wire 31, and the third multicore collectively shielded wire 41 are bent inward at the portion where the waterproof member 54 is provided. This prevents the problem of being damaged.

Next, the operation of the wire harness 11 configured as described above will be explained.
The first multicore collectively shielded electric wire 21 has a first electromagnetic shielding member 26 that collectively covers the outer periphery of the first positive core wire 22 and the first negative core wire 24 via the

inner insulation coatings

23 and 25. Emission of electromagnetic waves from the core collectively shielded electric wire 21 is suppressed. Moreover, since the second multicore collectively shielded electric wire 31 has a second electromagnetic shielding member 36 that collectively covers the outer circumferences of the second positive core wire 32 and the second negative core wire 34 via the

inner insulation coatings

33 and 35, Emission of electromagnetic waves from the two multi-core collectively shielded electric wire 31 is suppressed. Further, the third multi-core collectively shielded electric wire 41 includes a third electromagnetic shielding member 46 that collectively covers the outer circumferences of the third positive core wire 42 and the third negative core wire 44 via the

inner insulation coatings

43 and 45. Emission of electromagnetic waves from the three-core multi-core shielded electric wire 41 can be suppressed. Further, the first connecting portion 16 and the second connecting portion 17 are covered with a shield connecting member 52 to which the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46 are connected to the outer peripheral surface. . Therefore, radiation of electromagnetic waves from the vicinity of the first connecting portion 16 and the second connecting portion 17 is suppressed.

Next, the effects of the above embodiment will be described below.
(1) All the electromagnetic shielding members, the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46, are connected to the insulating member 51 that covers the first connecting portion 16 and the second connecting portion 17. Connected on the outside. Therefore, radiation of electromagnetic waves from the vicinity of the first connecting portion 16 and the second connecting portion 17 is suppressed. The configuration is simpler than, for example, a configuration in which the outer peripheries of the first connection part 16 and the second connection part 17 are each covered with separate electromagnetic shielding members. In addition, since the shielded wires are the first multi-core collectively shielded wire 21, the second multi-core collectively shielded wire 31, and the third multi-core collectively shielded wire 41, the configuration is simpler than when the shielded wires are each core shielded wire. becomes. That is, for example, in the case where all of the plurality of shielded wires are core shielded wires each having one electromagnetic shielding member for one core wire, the number of electromagnetic shielding members increases, which increases the manufacturing man-hours and the configuration. It gets complicated. On the other hand, in this embodiment, for example, a plurality of electromagnetic shielding members are grouped together, so the configuration is simple.

(2) The plurality of shielded wires included in the wire harness 11 are all multicore collectively shielded wires, and include the first multicore collectively shielded wire 21 , the second multicore collectively shielded wire 31 , and the third multicore collectively shielded wire 41 It is. Therefore, the configuration is simpler than, for example, a case where at least one of the plurality of shielded wires is a core shielded wire having one electromagnetic shielding member for one core wire.

(3) Each of the first connecting portion 16 and the second connecting portion 17 has a flat cross-sectional shape, and is stacked in a direction in which the cross-sectional shape is thinner. Therefore, the wire harness 11 can be made more compact than a configuration in which the first connecting portion 16 and the second connecting portion 17 are arranged in other directions.

(4) The number of core wires in each of the first multicore collectively shielded electric wire 21, the second multicore collectively shielded electric wire 31, and the third multicore collectively shielded electric wire 41, and the first connection portion 16 which is the stacked connection portion and the number of second connection portions 17 are the same. In this way, all of the core wires in the multi-core collectively shielded electric wire are stacked, so that the wire harness 11 can be made into a compact shape.

(5) The wire harness 11 is a waterproof member that collectively covers the first connecting portion 16, the second connecting portion 17, the insulating member 51, the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46. 54. Therefore, the first connecting portion 16, the second connecting portion 17, the insulating member 51, the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46 are not exposed to water by the single waterproof member 54. You can prevent all of these things at once.

(6) Each of the first multi-core collectively shielded electric wire 21, the second multi-core collectively shielded electric wire 31, and the third multi-core collectively shielded electric wire 41 is provided with a spacer that fills a void inside the part corresponding to the portion where the waterproof member 54 is provided. It has a member 57. Therefore, the spacer member prevents the outer surfaces of the first multi-core collectively shielded wire 21, the second multi-core collectively shielded wire 31, and the third multi-core collectively shielded wire 41 from bending inward at the portion where the waterproof member 54 is provided. 57. Therefore, it is possible to prevent gaps from forming between the outer surfaces of the first multi-core collectively shielded electric wire 21, the second multi-core collectively shielded electric wire 31, and the third multi-core collectively shielded electric wire 41 and the waterproof member 54, and as a result, the waterproof member It is possible to prevent liquid from entering the inside of 54.

(7) The insulating member 51 is configured to be disposed from the outside of the first connecting portion 16 and the second connecting portion 17. Specifically, in this embodiment, the first insulating member 14 that constitutes a part of the insulating member 51 is configured to be disposed from the outside of the first connecting portion 16 . Further, the second insulating member 15 , which constitutes a part of the insulating member 51 , is configured to be disposed from the outside of the second connecting portion 17 . Therefore, the insulating member 51 does not need to be assembled in advance, for example, before connecting the core wires in the first connection part 16 and the second connection part 17, so that the assemblability becomes good.

(8) The first connecting portion 16 and the second connecting portion 17 are covered by the shield connecting member 52 via the insulating member 51. Further, the first electromagnetic shielding member 26 , the second electromagnetic shielding member 36 , and the third electromagnetic shielding member 46 are connected to the shield connecting member 52 . Therefore, radiation of electromagnetic waves from the periphery of the first connecting portion 16 and the second connecting portion 17 can be effectively suppressed. In addition, in the same configuration, the first connecting portion 16 and the second connecting portion 17 are collectively covered by the single shield connecting member 52, so for example, the first connecting portion 16 and the second connecting portion 17 are This is a simpler configuration than a configuration in which each shield is covered with a separate shield connecting member.

(9) The shield connecting member 52 configured to be disposed from the outside of the insulating member 51 does not require the first multi-core bulk shielded wire 21 to be passed through it in advance, as in the case of, for example, a cylindrical pipe. , the ease of assembly is improved.

(10) The wire harness 11 includes a caulking member 53 as a fixing member that fixes the shield connecting member 52 and the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46. Therefore, for example, the shield connecting member 52 and the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46 can be easily connected without performing complicated welding work or the like.

(11) The caulking member 53 is provided so as to surround the shield connecting member 52, the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46, with the shield connecting member 52 as a base. , is fixed by caulking. Therefore, the shield connecting member 52 and the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46 can be easily connected by caulking and fixing.

(12) By providing the first insulating member 14 on the first connecting portion 16 and the second insulating member 15 on the second connecting portion 17, the first insulating member 14 is provided between the first connecting portion 16 and the second connecting portion 17. At the same time, insulation can be easily ensured by the insulating member 51 covering the outer periphery of the first connecting portion 16 and the second connecting portion 17.

This embodiment can be modified and implemented as follows. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

For example, as shown in FIG. 8, the waterproof member 61 may be composed of a resin pipe 62 and rubber plugs 63 and 64. The resin pipe 62 is formed in a cylindrical shape to cover the shield connecting member 52 and the like. One rubber stopper 63 is provided so as to close the gap between the open end of the resin pipe 62 on one side and the outer periphery of the outer insulation coating 27 . The other rubber plug 64 is provided to close the gap between the other open end of the resin pipe 62 and the outer periphery of the

outer insulation coatings

37 and 47.

Additionally, the wire harness 11 includes

retainers

65 and 66 to prevent the rubber plugs 63 and 64 from shifting. The

retainers

65 and 66 are fixed adjacent to the rubber plugs 63 and 64 on the outer periphery of the

outer insulation coatings

27 , 37 and 47 to prevent the rubber plugs 63 and 64 from shifting, that is, from coming off the resin pipe 62 . In this example as well, each of the first multicore collectively shielded electric wire 21, the second multicore collectively shielded electric wire 31, and the third multicore collectively shielded electric wire 41 is located at a portion of the waterproof member 61 where the rubber plugs 63 and 64 are provided. It is preferable to have a spacer member 57 in the corresponding interior to fill the void.

Even if this is done, the first connection part 16, the second connection part 17, the insulating member 51, the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, the third electromagnetic shielding member 46, etc. will be exposed to water. This can be prevented.

Although it is assumed that the shielded wire 41 is used, the present invention is not limited to this. For example, if at least one of the first multi-core collectively shielded wire 21, the second multi-core collectively shielded wire 31, and the third multi-core collectively shielded wire 41 is a multi-core collectively shielded wire, the others are Each core shielded wire may have one electromagnetic shielding member.

- In the above embodiment, each of the first connecting portion 16 and the second connecting portion 17 has a flat cross-sectional shape, and is stacked in the direction of thinner cross-sectional shapes, but the present invention is not limited to this. For example, each of the first connecting portion 16 and the second connecting portion 17 does not need to have a flat cross-sectional shape. Further, for example, each of the first connecting portion 16 and the second connecting portion 17 may have a flat cross-sectional shape, but may be arranged in a direction different from that in the above embodiment.

- In the above embodiment, the wire harness 11 includes the

waterproof members

54, 61 that collectively cover the first connecting portion 16, the second connecting portion 17, etc., but the present invention is not limited to this. A configuration may also be adopted in which this is not provided. Furthermore, the

The first waterproof member 72 is a molded resin in which a non-conductive resin material is provided so as to cover the outer periphery of the first connecting portion 16 and fill the inner gap. Further, the second waterproof member 73 is a molded resin in which a non-conductive resin material is provided so as to cover the outer periphery of the second connecting portion 17 and fill the inner gap. The connecting portion waterproof member 71 is interposed between the first connecting portion 16 and the second connecting portion 17 and the shield connecting member 52. In this example, the shield connecting member 52 is arranged from the outside of the connection part waterproof member 71 after the connection part waterproof member 71 which also serves as an insulating member is provided.

Even in this case, the first connecting portion 16 and the second connecting portion 17 can be prevented from being exposed to water by the connecting portion waterproof member 71. Further, compared to a configuration including

waterproof members

54 and 61 that collectively cover the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, the third electromagnetic shielding member 46, etc., the size can be reduced, for example. Further, for example, with miniaturization, it is possible to reduce the amount of materials and manufacturing costs. Note that the wire harness 11 equipped with the

waterproof members

54 and 61 and the wire harness 11 equipped with the connecting portion waterproof member 71 are two types of products with different waterproof types, and are provided, for example, according to the user's request. can do.

In addition, since the connecting portion waterproof member 71 also serves as an insulating member, the configuration can be simplified compared to a case where the connecting portion waterproof member 71 is provided separately and independently from the insulating member 51.
Further, since the connection portion waterproof member 71 is made of non-conductive molded resin, the connection portion waterproof member 71 which also serves as an insulating member can be easily provided.

Further, since the connecting portion waterproof member 71 is interposed between the first connecting portion 16 and the second connecting portion 17 and the shield connecting member 52, it is possible to configure the connecting portion waterproof member 71 so that it is not disposed outside the shield connecting member 52. can. Therefore, the connection portion waterproofing member 71 can avoid interfering with the connection between the shield connecting member 52 and the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46.

In addition, by providing the first waterproof member 72 on the first connecting portion 16 and the second waterproof member 73 on the second connecting portion 17, it is possible to prevent the first waterproof member 72 from intervening between the first connecting portion 16 and the second connecting portion 17. At the same time, insulation can be easily ensured by the connection part waterproof member 71 that covers the outer periphery of the first connection part 16 and the second connection part 17.

Further, although the connecting portion waterproof member 71 has been described as also serving as an insulating member, the present invention is not limited to this, and the connecting portion waterproof member may include an insulating member separately from the waterproof member.
Further, although the connection portion waterproof member 71 is made of non-conductive molded resin, it is not limited thereto, and may have other configurations. For example, the connection portion waterproof member may be a shrink tube. For example, the connection part waterproofing member includes a pipe that collectively covers the first connection part 16 and the second connection part 17, and a pipe that prevents liquid from reaching the first connection part 16 and the second connection part 17 by blocking the open end of the pipe. It may also be constructed with a rubber stopper that prevents the

For example, the insulating member 51 includes an annular member that collectively covers the outer circumferences of the first connecting portion 16 and the second connecting portion 17, and an intervening member that is interposed between the first connecting portion 16 and the second connecting portion 17. It is good also as a structure which has. Further, for example, the insulating member 51 includes an annular portion that collectively covers the outer circumferences of the first connecting portion 16 and the second connecting portion 17, and an intervening portion that is interposed between the first connecting portion 16 and the second connecting portion 17. The portion may be integrally formed with an insulating tape or the like, for example. That is, the insulating member 51 may have another configuration as long as it can insulate the first connecting portion 16 and the second connecting portion 17 from each other.

- In the above embodiment, the first insulating member 14 is an insulating tape wrapped around the outside of the first connecting portion 16, but the present invention is not limited to this, and may be changed to another insulating member. Further, in the embodiment described above, the second insulating member 15 is an insulating tape wrapped around the outside of the second connecting portion 17, but the present invention is not limited thereto, and may be changed to another insulating member. For example, at least one of the first insulating member 14 and the second insulating member 15 may be changed to a resin molded product.

- In the above embodiment, the wire harness 11 includes the shield connecting member 52, but it may be configured without the shield connecting member 52.

For example, the shield connecting member 52 may be formed into a C-shape with a circumferential portion cut out from a cylindrical shape, and the insulating member 51 may be passed inside through the C-shaped opening. Further, for example, the shield connecting member 52 may be made of a sheet-like shield portion that has flexibility and can be wrapped around the insulating member 51 from the outside.

- In the above embodiment, the wire harness 11 includes the caulking member 53 as a fixing member, but the present invention is not limited to this. For example, the caulking member 53 may not be provided. For example, the shield connecting member 52 and the first electromagnetic shielding member 26, the second electromagnetic shielding member 36, and the third electromagnetic shielding member 46 may be welded. Further, the fixing member may be changed to a fixing member that is fixed by a configuration other than caulking. Further, the caulking member 53 may be a C-shaped ring.
