[Figure 2] FIG. 2 is a cross-sectional view of a housing of an electrical device and a wire harness according to an embodiment. [Figure 3] FIG. 3 is a partially exploded perspective view of the wire harness according to the embodiment. [Figure 4] FIG. 4 is an exploded perspective view of a connector according to one embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: [1] A connector that is fixed to the end of a shielded electric wire having a core wire, an insulating coating covering the outer periphery of the core wire, and a shielding member covering the outer periphery of the insulating coating, and is fixed to an attachment object, thereby electrically connecting the shielding member to the attachment object, and includes: a metal pipe through which the core wire and the insulating coating are passed and to which the shielding member is connected; and a metal fixing member that is fixed to the outer surface of the metal pipe and fixed to the attachment object.

[0010] According to this configuration, the core wire is covered by the metal pipe, and the shielding member is connected to the attachment object via the metal pipe and the metal fixing member. This suppresses electromagnetic wave radiation from the core wire. Here, the metal pipe and the metal fixing member are each separately manufactured and then fixed to each other, making them easy to obtain. Furthermore, since the connector does not include a resin molded part and does not require a mold, the connector can be easily manufactured.

[0011] [2] In the above item [1], it is preferable that the metal fixing member is made of a plate material. According to this configuration, the metal fixing member can be manufactured more easily than a casting.

[0012] [3] In the above [1] or [2], it is preferable that the metal fixing member has a pipe fixing hole, and the metal pipe has a first expanded portion that is joined to the inner surface of the pipe fixing hole.

[0013] According to this configuration, the metal pipe can be expanded before being joined to the inner surface of the pipe fixing hole, making the fixing operation easier than by welding. [4] In any one of the above [1] to [3], it is preferable to include a first rubber ring fitted onto the metal pipe.

[0014] According to this configuration, by interposing the first rubber ring between the outer circumferential surface of the metal pipe and the attachment object, it is possible to waterproof this portion. [5] In the above item [4], it is preferable that the metal pipe has a first narrowed portion onto which the first rubber ring is fitted.

[0015] According to this configuration, displacement of the first rubber ring along the length of the metal pipe is suppressed. [6] In any one of the above [1] to [5], it is preferable to include a second rubber ring fitted inside the metal pipe.

[0016] According to this configuration, by interposing the second rubber ring between the inner circumferential surface of the metal pipe and the outer circumferential surface of the insulating coating, it is possible to waterproof this portion. [7] In the above item [6], it is preferable that the metal pipe has a second expanded portion into which the second rubber ring is fitted.

[0017] According to this configuration, the second rubber ring is prevented from shifting in position along the length of the metal pipe. [8] In any one of the above items [1] to [7], the metal pipe preferably has a second reduced section that is pressure-welded to the insulating coating.

[0018] According to this configuration, the insulating coating and the connector can be fixed together by the second tube-reducing portion without using a separate member. [9] In any one of the above [1] to [8], it is preferable that the shielded electric wire is a multi-core collective shielded electric wire having a plurality of the core wires and the insulating coatings, and the shielding member covers the plurality of insulating coatings collectively, and that the shielded electric wire is provided with a plurality of the metal pipes through which the core wires and the insulating coatings are passed one by one as a set, and that the metal fixing member is fixed to at least one of the plurality of metal pipes so that the axes of the plurality of metal pipes are parallel to each other, and is provided with a connecting member that is arranged to fill the gaps between the outer surfaces of the plurality of metal pipes and to which the shielding member is connected.

[0019] According to this configuration, the connecting member can satisfactorily electrically connect the shielding member of the multi-core shielded electric wire to the metal pipe. That is, in a configuration without a connecting member, the shielding member does not or has difficulty making contact in the gaps between the outer circumferential surfaces of the multiple metal pipes, resulting in a small contact area. However, this configuration can avoid this.

[0020]

[10] In the above [7], it is preferable that the shielded electric wire is a multi-core collective shielded electric wire having a plurality of the core wires and the insulating coatings, and the shielding member covers the plurality of insulating coatings collectively, and that the shielded electric wire is provided with a plurality of metal pipes through which the core wires and the insulating coatings are passed one by one as a set, and that the metal fixing member is fixed to at least one of the plurality of metal pipes so that the axes of the plurality of metal pipes are parallel to each other, and is provided with a connecting member that is arranged to fill the gap between the outer circumferential surfaces of the second expansion portions of the plurality of metal pipes and to which the shielding member is connected.

[0021] According to this configuration, in addition to the effect of [9], the gap between the outer peripheral surfaces of the second expansion section is smaller than the gap between the outer peripheral surfaces of other parts that have not been expanded, thereby reducing the material cost of the connecting member that is provided to fill the gap.

[0022] The wire harness of the present disclosure includes:

[11] The connector includes any one of the connectors [1] to

[10] above and the shielded electric wire.

[0023] This configuration provides the same effects as those of a connector.

[12] A wire harness comprising the connector according to [9] or

[10] above and the shielded electric wire, further comprising a crimping member for crimping and fixing the shielding member to the connecting member.

[0024] According to this configuration, in addition to the effect of

[11] , the shielding member can be easily connected to the connecting member by the crimping member. [Details of the embodiments of the present disclosure] Specific examples of the wire harness of the present disclosure will be described below with reference to the drawings. In each drawing, for convenience of explanation, some of the configuration may be exaggerated or simplified. Furthermore, the dimensional ratios of each part may differ between drawings. In this specification, "parallel," "orthogonal," and "circular" do not only refer to strictly parallel, orthogonal, or circular, but also include approximately parallel, orthogonal, or circular within the scope of the effects of this embodiment. Note that the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0025] (Configuration of wire harness 10) As shown in FIG. 1, the wire harness 10 includes a multi-core unit shielded electric wire 20 as a shielded electric wire, and a connector 30.

[0026] (Configuration of multi-core shielded electric wire 20) 1 to 3, the multi-core shielded electric wire 20 includes electric wires 21 and a shielding member 22. The multi-core shielded electric wire 20 of this embodiment includes three electric wires 21.

[0027] The electric wire 21 has a core wire 23 and an insulating coating 24 that covers the outer periphery of the core wire 23. The core wire 23 in this embodiment has a circular cross-sectional shape. The insulating coating 24 has an annular cross-sectional shape.

[0028] The shielding member 22 covers the outer periphery of the insulating coating 24. In this embodiment, the shielding member 22 collectively covers a plurality of insulating coatings 24. The shielding member 22 is, for example, a braided wire in which conductive wires such as copper alloy or aluminum alloy are braided into a cylindrical shape. Note that the shielding member 22 is illustrated schematically in each drawing. The end of the electric wire 21 protrudes outward from the end of the shielding member 22.

[0029] (Configuration of connector 30) As shown in FIG. 2, the connector 30 is fixed to an end of the multi-core unit shielded electric wire 20, and is also fixed to a housing 50 of an electric device to which it is attached.

[0030] 1 to 4, the connector 30 includes a metal pipe 31 and a metal fixing member 32 fixed to the outer circumferential surface of the metal pipe 31. The connector 30 of this embodiment corresponds to the three electric wires 21 of the multi-core shielded electric wire 20 and includes three metal pipes 31. That is, the connector 30 includes three metal pipes 31, and one electric wire 21 is passed through each of the metal pipes 31. In other words, one set of a core wire 23 and an insulating coating 24 is passed through each of the metal pipes 31.

[0031] (Configuration of metal fixing member 32) The metal fixing member 32 is made of a plate material. Specifically, the metal fixing member 32 is made by punching a metal plate material.

[0032] As shown in FIG. 4, the metal fixing member 32 has a rectangular main body 32a when viewed in the thickness direction, and fixing portions 32b protruding in the short direction from both longitudinal ends of the main body 32a. The metal fixing member 32 has pipe fixing holes 32c penetrating in the thickness direction. Three pipe fixing holes 32c are formed in the main body 32a. The three pipe fixing holes 32c are arranged in parallel at equal intervals along the longitudinal direction of the main body 32a. The inner surfaces of the pipe fixing holes 32c are preferably subjected to a textured finish such as knurling. The metal fixing member 32 also has connector mounting holes 32d penetrating in the thickness direction. The connector mounting holes 32d are formed in each of the two fixing portions 32b.

[0033] (Configuration of metal pipe 31) The metal pipe 31 is made of a pipe material. Specifically, the metal pipe 31 is made by subjecting a metal pipe material with a fixed diameter to a pipe expansion process to widen the diameter or a pipe reduction process to reduce the diameter.

[0034] As shown in FIG. 2, the metal pipe 31 has a first expanded tube portion 31a that is joined to the inner surface of the pipe fixing hole 32c. The first expanded tube portion 31a is a portion of the metal pipe 31 that has a larger diameter than adjacent portions in the longitudinal direction. The first expanded tube portion 31a is provided in the middle portion of the metal pipe 31. When the first expanded tube portion 31a is formed by pipe expansion, the first expanded tube portion 31a is pressed against and joined to the inner surface of the pipe fixing hole 32c, thereby fixing the metal pipe 31 to the metal fixing member 32. In other words, the metal pipe 31 is expanded in the pipe fixing hole 32c to form the first expanded tube portion 31a, thereby fixing the metal fixing member 32 to the metal pipe 31.

[0035] 3 and 4, the metal fixing member 32 is fixed to the plurality of metal pipes 31 so that the axes Z of the plurality of metal pipes 31 are parallel to each other. Note that Fig. 4 is not an exploded perspective view of the metal pipe 31 and the metal fixing member 32 before they are fixed to each other, but shows the metal pipe 31 having the first expanded portion 31a in a state where the metal pipe 31 and the metal fixing member 32 have been fixed to each other and then disassembled again.

[0036] The metal pipe 31 also has a first reduced tube portion 31b. The first reduced tube portion 31b is a portion of the metal pipe 31 whose diameter is smaller than that of an adjacent portion in the longitudinal direction. The first reduced tube portion 31b is provided closer to the tip end of the metal pipe 31 than the first expanded tube portion 31a. More specifically, the metal pipe 31 has a first end portion 31c arranged closer to the tip end of the wire harness 10, and a second end portion 31d arranged closer to the middle portion of the wire harness 10. The first reduced tube portion 31b is provided closer to the first end portion 31c than the first expanded tube portion 31a.

[0037] The connector 30 includes a first rubber ring 33 fitted onto the metal pipe 31. The first rubber ring 33 is fitted onto the first narrowed portion 31b. The metal pipe 31 also has a second expanded tube portion 31e. The second expanded tube portion 31e is a portion of the metal pipe 31 whose diameter is larger than that of an adjacent portion in the longitudinal direction. The second expanded tube portion 31e is provided closer to the second end portion 31d than the first expanded tube portion 31a, with a gap between it and the first expanded tube portion 31a. Between the first expanded tube portion 31a and the second expanded tube portion 31e, there is provided a basic portion 31f which has not been subjected to expansion or reduction processing and which maintains the original diameter of the pipe material constituting the metal pipe 31.

[0038] The connector 30 includes a second rubber ring 34 fitted inside the metal pipe 31. The second rubber ring 34 is fitted inside the second expanded tube portion 31e. The electric wire 21 is passed through the metal pipe 31. With the electric wire 21 passed through the metal pipe 31, the second rubber ring 34 is interposed in a compressed state between the outer circumferential surface of the insulating coating 24 and the inner circumferential surface of the metal pipe 31.

[0039] The metal pipe 31 also has a second narrowed portion 31g that is pressed against the insulating coating 24. The second narrowed portion 31g is a portion of the metal pipe 31 that has a smaller diameter than an adjacent portion in the longitudinal direction. The second narrowed portion 31g is provided at the second end portion 31d. The metal pipe 31 is fixed to the electric wire 21 by the second narrowed portion 31g being pressed against the insulating coating 24.

[0040] As shown in FIGS. 3 and 4, the connector 30 includes a connection member 35. As shown in FIG. 4, the connection member 35 has three through holes 35a into which the metal pipes 31 are fitted. The through holes 35a are sized to fit the second expanded portions 31e of the metal pipes 31. The connection member 35 is provided to cover the three metal pipes 31 and fill gaps 36 between the outer circumferential surfaces 31h of the three metal pipes 31. More specifically, the connection member 35 is provided to cover the second expanded portions 31e of the three metal pipes 31 and fill gaps 36 between the outer circumferential surfaces 31h of the second expanded portions 31e of the three metal pipes 31. That is, the connection member 35 fills gaps 36 formed between the outer circumferential surfaces 31h of the metal pipes 31 at connection portions 35b between the through holes 35a.

[0041] As shown in FIG. 2 , the shielding member 22 is connected to the outer peripheral surface of the connecting member 35. More specifically, the wire harness 10 includes a crimping member 37. The shielding member 22 is disposed so as to cover the outer peripheral surface of the connecting member 35, and the crimping member 37 is crimped to the outside of the shielding member 22, thereby connecting the shielding member 22 to the connecting member 35. That is, the connecting member 35 serves as a base when the crimping member 37 is crimped, and is in contact with the shielding member 22 over its entire circumference. The crimping member 37 crimps and fixes the shielding member 22 to the connecting member 35. In this embodiment, the crimping member 37 is a metal crimping ring formed in an annular shape. The shielding member 22 is electrically connected to the metal pipe 31 via the connecting member 35.

[0042] An end of the core wire 23 protrudes from the first end 31c of the metal pipe 31 and is exposed from the insulating coating 24. A terminal 38 is fixed to the end of the core wire 23 by crimping.

[0043] (Configuration of the housing 50 of the electrical device and the fixing structure of the connector 30) 2, the housing 50 of the electrical device to which the connector 30 is to be attached includes a mounting hole 50a and a fastening portion 50b. The housing 50 of the electrical device is made of metal. The connector 30 is fixed to the housing 50 of the electrical device so that the terminal 38 and the first end 31c of the metal pipe 31 are inserted into the mounting hole 50a.

[0044] With the first end 31c of the metal pipe 31 inserted into the mounting hole 50a, the first rubber ring 33 is interposed in a compressed state between the outer circumferential surface of the metal pipe 31 and the inner circumferential surface of the mounting hole 50a. The connector 30 is fixed to the housing 50 of the electrical device by a bolt 39 that passes through the connector mounting hole 32d and is screwed into the fastening portion 50b. This electrically connects the shield member 22 to the housing 50 of the electrical device via the connector 30. With the connector 30 fixed to the housing 50 of the electrical device, a terminal (not shown) of the electrical device is connected to the terminal 38.

[0045] Next, the operation of the wire harness 10 configured as above will be described. In the multi-core shielded electric wire 20, the insulating coatings 24 of the multiple electric wires 21 are collectively covered by the shielding member 22. This suppresses radiation of electromagnetic waves from the core wires 23 in the area covered by the shielding member 22. Furthermore, the connector 30 is fixed to the housing 50 of the electric device, so that the shielding member 22 is electrically connected to the housing 50 of the electric device. In the connector 30, the electric wires 21 are covered by the metal pipe 31. This suppresses radiation of electromagnetic waves from the core wires 23 in the area of ​​the connector 30.

[0046] Next, the effects of the above embodiment will be described below. (1) In the connector 30, the core wire 23 is covered by the metal pipe 31. The shielding member 22 is connected to the housing 50 of the electrical device via the metal pipe 31 and the metal fixing member 32. This makes it possible to suppress radiation of electromagnetic waves from the core wire 23. The metal pipe 31 and the metal fixing member 32 are each separately manufactured and then fixed to each other, making them easy to obtain. Furthermore, since the connector 30 does not include a resin molded part and does not require a mold, the connector 30 can be easily manufactured.

[0047] (2) The metal fixing member 32 is made of a plate material, which makes it easier to manufacture the metal fixing member 32 than a casting, for example. (3) The metal pipe 31 has the first expanded portion 31a that is joined to the inner surface of the pipe fixing hole 32c, and can be joined to the inner surface of the pipe fixing hole 32c by expanding the metal pipe 31. Therefore, the fixing work is easier than, for example, welding.

[0048] (4) The connector 30 includes a first rubber ring 33 fitted onto the metal pipe 31. Therefore, by interposing the first rubber ring 33 between the outer circumferential surface of the metal pipe 31 and the inner circumferential surface of the mounting hole 50a in the housing 50 of the electrical device, the relevant portion can be waterproofed. The first rubber ring 33 does not require a special shape and can be made simple, and can be assembled simply by fitting it onto the metal pipe 31, making it easy to manufacture the connector 30.

[0049] (5) The metal pipe 31 has the first reduced portion 31b onto which the first rubber ring 33 is fitted. Therefore, displacement of the first rubber ring 33 along the length of the metal pipe 31 is suppressed.

[0050] (6) The connector 30 includes a second rubber ring 34 that is fitted inside the metal pipe 31. Therefore, by interposing the second rubber ring 34 between the inner peripheral surface of the metal pipe 31 and the outer peripheral surface of the insulating coating 24, it is possible to waterproof that portion. The second rubber ring 34 does not require a special shape and can be made simple, and can be assembled simply by fitting it inside the metal pipe 31, making it easy to manufacture the connector 30.

[0051] (7) The metal pipe 31 has the second expanded portion 31e into which the second rubber ring 34 is fitted. Therefore, displacement of the second rubber ring 34 along the length of the metal pipe 31 is suppressed.

[0052] (8) The metal pipe 31 has the second narrowed portion 31g that is pressure-welded to the insulating coating 24. Therefore, the insulating coating 24 and the connector 30 can be fixed by the second narrowed portion 31g without using a separate member.

[0053] (9) The connecting member 35 is provided so as to fill the gaps 36 between the outer circumferential surfaces 31h of the plurality of metal pipes 31, and is connected to the shielding member 22. This allows the shielding member 22 in the multi-core shielded electric wire 20 to be electrically connected to the metal pipes 31 in a satisfactory manner. That is, in a configuration without the connecting member 35, the shielding member 22 does not or has difficulty making contact with the gaps 36 between the outer circumferential surfaces 31h of the plurality of metal pipes 31, resulting in a small contact area. However, this configuration can avoid this. This allows the shielding member 22 to be connected to the metal pipes 31 in a satisfactory manner.

[0054] (10) The connecting member 35 is provided to fill the gap 36 between the outer circumferential surfaces 31h of the second expanded pipe portions 31e in the metal pipe 31. The gap 36 between the outer circumferential surfaces 31h of the second expanded pipe portions 31e is smaller than the gap between the outer circumferential surfaces of other portions that are not expanded, so the material cost of the connecting member 35 provided to fill the gap 36 can be reduced.

[0055] (11) The shield member 22 can be easily connected to the connecting member 35 by the crimping member 37. This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0056] In the above embodiment, the metal fixing member 32 is made of a plate material, but is not limited to this and may be, for example, a cast product formed using a mold. Also, while the metal fixing member 32 is made by punching a metal plate material, it may be made of a plate material and subjected to other processing such as bending.

[0057] In the above embodiment, the metal pipe 31 has the first expanded portion 31a that is joined to the inner surface of the pipe fixing hole 32c, but this is not limited thereto, and the metal pipe 31 may not have the first expanded portion 31a. For example, the metal pipe and the metal fixing member may be fixed by welding.

[0058] In the above embodiment, the connector 30 includes the first rubber ring 33 fitted onto the metal pipe 31, but this is not limitative and the connector 30 may not include the first rubber ring 33. For example, instead of the first rubber ring 33, a sealing member may be fixed to the metal fixing member 32 by adhesive or the like.

[0059] In the above embodiment, the metal pipe 31 has the first narrowing portion 31b onto which the first rubber ring 33 is fitted, but this is not limited to this, and the metal pipe 31 may be configured without the first narrowing portion 31b.

[0060] In the above embodiment, the connector 30 includes the second rubber ring 34 fitted into the metal pipe 31, but this is not limitative and the connector 30 may not include the second rubber ring 34. For example, instead of the second rubber ring 34, a sealing member may be fixed to the second end 31d of the metal pipe 31 by adhesive or the like.

[0061] In the above embodiment, the metal pipe 31 has the second expanded portion 31e into which the second rubber ring 34 is fitted, but this is not limited thereto, and the metal pipe 31 may be configured without the second expanded portion 31e. Also, instead of forming the second expanded portion 31e independently, the first expanded portion 31a may be used as the second expanded portion, and the second rubber ring 34 may be fitted into the first expanded portion 31a, which also constitutes the second expanded portion.

[0062] In the above embodiment, the metal pipe 31 has the second narrowing portion 31g that is pressed against the insulating coating 24, but this is not limited thereto, and the metal pipe 31 may not have the second narrowing portion 31g. For example, the insulating coating 24, and therefore the electric wire 21, may be fixed to the metal pipe 31 by a separate member.

[0063] In the above embodiment, the connector 30 includes the connecting member 35, but this is not limiting and the connector 30 may not include the connecting member 35. In particular, in the above embodiment, the shielded electric wire is a multi-core batch shielded electric wire 20, and therefore the connecting member 35 is provided to electrically connect the shielding member 22 to the metal pipe 31 satisfactorily. However, in a configuration in which an independent shielding member is provided for each electric wire 21, the connecting member 35 is not necessary. That is, in a configuration in which the shielded electric wire is a core-shielded electric wire and an independent shielding member is provided for each electric wire 21, each shielding member may be directly connected to the metal pipe 31.

[0064] In the above embodiment, the connecting member 35 is arranged to fill the gap 36 between the outer peripheral surfaces 31h of the second expansion section 31e, but this is not limited to this, and the connecting member 35 may be arranged to fill the gap between the outer peripheral surfaces of parts of the metal pipe 31 other than the second expansion section 31e.

[0065] In the above embodiment, the crimping member 37 is provided, but this is not limitative. For example, the crimping member 37 may not be provided, and the shielding member 22 may be fixed to the connecting member 35 by welding.
