[0008] (Description of embodiments of this disclosure) First, embodiments of this disclosure will be described. (1) The wire harness disclosed herein comprises a plurality of shielded wires, each of the plurality of shielded wires having a core wire, an insulating covering portion covering the outer periphery of the core wire, and a shielding member covering the outer periphery of the insulating covering portion. The wire harness comprises: a core wire connecting portion for connecting the core wires of the plurality of shielded wires to each other; an insulating member covering the outer periphery of the core wire connecting portion; a conductive housing covering the outer periphery of the insulating member and covering the outer periphery of the plurality of shielded wires; and a sealing member for sealing the housing and the plurality of shielded wires, the housing having a connecting portion electrically connected to each of the plurality of shielding members.

[0009] According to this configuration, the outer periphery of the core wire connection is covered by a conductive shell, which is electrically connected to multiple shielding members. This allows the shell to function as an electromagnetic shielding member, suppressing electromagnetic wave (electromagnetic noise) radiation from the core wire connection. Furthermore, a sealing member seals the shell between it and the multiple shielded wires. This allows the shell and sealing member to function as waterproof members, preventing water immersion in the core wire connection. Thus, the shell functions as both an electromagnetic shielding member and a waterproof member. Therefore, compared to cases where the electromagnetic shielding member and waterproof member are separate components, the number of components in the wire harness can be reduced. As a result, the number of assembly steps for the wire harness can be reduced, thus improving the ease of assembly.

[0010] (2) In (1) above, the housing may also have a plurality of segments that can be joined together and a fixing member that fixes the plurality of segments into a joined state. The housing is formed into a cylindrical shape that surrounds the outer periphery of the insulating member and the outer periphery of the plurality of shielded wires by the joining of the plurality of segments.

[0011] According to this configuration, the housing is formed into a cylindrical shape by multiple segments, which surround the outer periphery of the insulating member and the outer periphery of multiple shielded wires. Thus, although the housing is formed into a cylindrical shape, by dividing the housing into multiple segments, the housing can be subsequently installed onto the shielded wires. Therefore, the assemblability of the housing relative to the shielded wires can be improved, and the assembly workability of the wire harness can be enhanced.

[0012] (3) In (2) above, the plurality of segments may also have a first segment and a second segment formed to be able to be combined with the first segment. The first segment has a first overlapping portion protruding from the circumferential end of the first segment toward the radially outer side of the housing. The second segment has a second overlapping portion protruding from the circumferential end of the second segment toward the radially outer side. The first overlapping portion has a first opposing surface opposite to the second overlapping portion and a first chamfered portion formed at the radially outer end of the first opposing surface. The second overlapping portion has a second opposing surface overlapping the first opposing surface and a second chamfered portion formed at the radially outer end of the second opposing surface. The housing has a groove formed by the first chamfered portion and the second chamfered portion. The wire harness has an adhesive filled into the groove. The adhesive constitutes the sealing member.

[0013] According to this configuration, when the first segment and the second segment are combined, the first opposing surface of the first segment and the second opposing surface of the second segment overlap, and a groove is formed by the first chamfer of the first segment and the second chamfer of the second segment. Furthermore, by filling the groove with adhesive, the first opposing surface and the second opposing surface can be properly sealed.

[0014] (4) In (3) above, the adhesive may also constitute the sealing member and the fixing member. According to this configuration, the adhesive functions as a sealing member that seals the space between the housing and the shielded wire, and also as a fixing member that secures the multiple components into a unified state. Therefore, compared to cases where the sealing and fixing members are composed of separate parts, the number of components in the wire harness can be reduced.

[0015] (5) In (3) or (4) above, the first segment and the second segment may have the same structure. According to this configuration, since the first and second segments constituting the shell are formed with the same structure, the increase in the number of parts, or more specifically, the types of parts, can be suppressed.

[0016] (6) In any of (1) to (5) above, each of the plurality of shielded wires may also have a sheath covering the outer periphery of the shielding member, the end of the shielding member having an exposed portion, the exposed portion protruding from the end of the sheath and folded back in a manner that surrounds the outer periphery of the end of the sheath, the connecting portion being formed as a cylinder surrounding the outer periphery of the exposed portion, and the inner peripheral surface of the connecting portion contacting the outer peripheral surface of the exposed portion.

[0017] According to this configuration, the inner circumferential surface of the cylindrical connecting part and the outer circumferential surface of the exposed part can be in contact with each other, so that the shell and the shielding member can be electrically connected to each other. (7) In (6) above, an interference fit may also be provided between the inner periphery of the connecting part and the outer periphery of the exposed part.

[0018] According to this configuration, the exposed portion of the shielded wire is fitted into the inner circumference of the cylindrical connecting portion with an interference fit. That is, when the shielded wire is fitted inside the connecting portion, the outer circumferential surface of the exposed portion contacts the inner circumferential surface of the connecting portion with an interference fit. Thus, the exposed portion of the shielded wire fitted inside the connecting portion contacts the inner circumferential surface of the connecting portion in a state where it is always pressed radially inward by the connecting portion. Therefore, proper contact between the inner circumferential surface of the connecting portion and the outer circumferential surface of the exposed portion can be achieved. Consequently, the electrical connection reliability between the housing and the shielding member can be improved.

[0019] (8) In (6) or (7) above, a washer may also be provided, the washer being disposed between the outer peripheral surface of the sheath and the inner peripheral surface of the exposed portion, the exposed portion being connected to the connecting portion in a state of being clamped by the washer and the connecting portion.

[0020] According to this configuration, the exposed portion is connected to the connecting portion in a state where it is clamped by the gasket and the connecting portion. This allows for proper contact between the inner circumferential surface of the connecting portion and the outer circumferential surface of the exposed portion. Consequently, the reliability of the electrical connection between the housing and the shielding member is improved.

[0021] (9) In any of (1) to (8) above, the plurality of shielded wires may have one or more first shielded wires and two or more second shielded wires, the one or more first shielded wires and the two or more second shielded wires extending in opposite directions from the core wire connection point, the housing having a first receiving part for receiving the one or more first shielded wires, a second receiving part for receiving the two or more second shielded wires, and a third receiving part for receiving the insulating member, the second receiving part having two or more receiving tubes for receiving the two or more second shielded wires respectively, and a partition wall provided between adjacent receiving tubes.

[0022] According to this configuration, the first shielded wire is housed in the first housing section of the housing, each of the second shielded wires is housed in a housing tube section of the second housing section, and the insulating member is housed in the third housing section. (10) In any of (1) to (9) above, the housing may also be made of die-cast aluminum.

[0023] Based on this structure, a conductive casing can be easily manufactured. (Details of the embodiments disclosed herein) Specific examples of the wire harness disclosed herein will be described below with reference to the accompanying drawings. In each drawing, for ease of explanation, some components are sometimes exaggerated or simplified. Furthermore, the dimensional ratios of the various parts may differ in different drawings. The terms "orthogonal" or "parallel" in this specification include not only strictly orthogonal or parallel cases, but also cases that are approximately orthogonal or parallel within the range that achieves the effect of this embodiment. In this specification, "identical" includes not only cases of exact sameness, but also cases where there are slight differences between the compared objects due to dimensional tolerances, etc. The term "cylindrical" as used in this specification includes not only shapes where the peripheral wall is continuously formed along the entire circumference, but also shapes formed by combining multiple components to form a cylindrical shape, or shapes such as C-shapes or U-shapes with a notch in a portion of the circumference. It should be noted that "cylindrical" shapes include, but are not limited to, circles, ellipses, and polygons with sharp or rounded corners. Furthermore, the terms "first," "second," "third," etc., in this specification are used only to distinguish objects and do not order the objects. The X-axis, Y-axis, and Z-axis are illustrated as mutually orthogonal in each drawing. The figures illustrate a first direction X1 along the X-axis and a first opposite direction X2. The figures also illustrate a second direction Y1 along the Y-axis and a second opposite direction Y2. Finally, the figures illustrate a third direction Z1 along the Z-axis and a third opposite direction Z2. It should be noted that the invention is not limited to these illustrations, but is intended to include all modifications within the meaning and scope of the claims.

[0024] (Composition of wire harness 10) like Figure 1 and Figure 2 As shown, the wiring harness 10 includes one first shielded wire 11 and two or more (two in this embodiment) second shielded wires 12. For example... Figure 2 As shown, the wire harness 10 includes a core wire connection portion 15, an insulating member 20 covering the outer periphery of the core wire connection portion 15, a conductive housing 30 covering the outer periphery of the insulating member 20, and an adhesive 60.

[0025] (Composition of the first shielded wire 11 and the second shielded wire 12) The first shielded wire 11 has a core wire 11a and an insulating covering portion 11b that covers the outer periphery of the core wire 11a. The first shielded wire 11 has a shielding member 11c that covers the outer periphery of the insulating covering portion 11b and a sheath 11d that covers the outer periphery of the shielding member 11c. The cross-sectional shape of the core wire 11a is, for example, circular.

[0026] Each second shielded wire 12 has a core wire 12a and an insulating covering portion 12b that covers the outer periphery of the core wire 12a. Each second shielded wire 12 has a shielding member 12c that covers the outer periphery of the insulating covering portion 12b and a sheath 12d that covers the outer periphery of the shielding member 12c. The cross-sectional shape of the core wire 12a is, for example, circular.

[0027] Shielding components 11c and 12c are components that suppress electromagnetic wave radiation from core wires 11a and 12a. Shielding components 11c and 12c are, for example, braided wires made of conductive wires such as copper alloys and aluminum alloys, woven into a cylindrical shape. It should be noted that the shape and appearance of the braided wires in shielding components 11c and 12c are schematically shown in the figures as appropriate.

[0028] At the ends of the first shielded wire 11 and each of the second shielded wires 12, the core wires 11a and 12a are exposed to the outside. At the ends of the first shielded wire 11 and each of the second shielded wires 12, shielding members 11c and 12c are exposed to the outside. The end of the shielding member 11c has an exposed portion 11e that protrudes from the end of the sheath 11d and is folded back to surround the outer periphery of the end of the sheath 11d. The exposed portion 11e is formed to fold back from the inside of the sheath 11d to the outside and cover the outer periphery of the sheath 11d. The end of each shielding member 12c has an exposed portion 12e that protrudes from the end of the sheath 12d and is folded back to surround the outer periphery of the end of the sheath 12d. The exposed portion 12e is formed to fold back from the inside of the sheath 12d to the outside and cover the outer periphery of the sheath 12d.

[0029] At the ends of the first shielded wire 11 and each of the second shielded wires 12, the sheaths 11d and 12d are first stripped. This exposes the ends of the shielding members 11c and 12c from the sheaths 11d and 12d. Next, the ends of the shielding members 11c and 12c are folded back to surround the outer periphery of the sheaths 11d and 12d. This creates exposed portions 11e and 12e at the ends of the shielding members 11c and 12c, which are exposed from the sheaths 11d and 12d and then folded back to surround the outer periphery of the sheaths 11d and 12d. Next, at the ends of the first shielded wire 11 and the second shielded wire 12, the insulation covering portions 11b and 12b are stripped. This exposes the core wires 11a and 12a from the insulation covering portions 11b and 12b.

[0030] The wiring harness 10, for example, has a washer 13 disposed between the sheaths 11d and 12d and the exposed portions 11e and 12e. The washer 13 is, for example, made of metal. The washer 13 is, for example, formed into a cylindrical shape that surrounds the outer periphery of the sheaths 11d and 12d. The washer 13 is, for example, disposed on the outer periphery of the sheaths 11d and 12d when the ends of the shielding members 11c and 12c are folded back.

[0031] The core wire connection portion 15 is constructed by connecting one core wire 11a and two core wires 12a. In the core wire connection portion 15 of this embodiment, the one core wire 11a and the two core wires 12a are directly soldered. One first shielded wire 11 and two second shielded wires 12 extend in opposite directions from the core wire connection portion 15. Specifically, with the core wire connection portion 15 as the base point, one first shielded wire 11 extends in a first direction X1, and two second shielded wires 12 extend in a first opposite direction X2. In other words, in the wire harness 10, at the middle portion of the length direction (here, the X-axis direction) of the wire harness 10, one first shielded wire 11 branches into two second shielded wires 12. The wire harness 10 electrically connects, for example, a battery connected to the core wire 11a of the first shielded wire 11 and an electrical device connected to the core wires 12a of each of the two second shielded wires 12.

[0032] (Composition of insulating component 20) The insulating member 20 is integrally formed in a cylindrical shape. The insulating member 20 covers the outer periphery of the core wire connection portion 15 circumferentially. The insulating member 20 covers the outer periphery of the core wire 11a exposed from the insulating cover portion 11b and the outer periphery of the core wire 12a exposed from the insulating cover portion 12b. The insulating member 20 is, for example, formed between the end of the insulating cover portion 11b and the ends of the two insulating cover portions 12b. For example, the end of the insulating member 20 in the first direction X1 covers the outer periphery of the end of the insulating cover portion 11b, and the end of the insulating member 20 in the first opposite direction X2 covers the outer periphery of the ends of the two insulating cover portions 12b. The end of the insulating member 20 in the first opposite direction X2 is formed to cover both insulating cover portions 12b together. The portion of the insulating member 20 that covers the two insulating covers 12b at the end in the first opposite direction X2 is larger in size along the second direction Y1 than the portion of the insulating member 20 that covers one insulating cover 11b. The insulating member 20, for example, has the function of maintaining the electrical insulation of the core wire connection portion 15 and the core wires 11a and 12a exposed from the insulating covers 11b and 12b.

[0033] As the insulating member 20, for example, heat shrink tubing, rubber tubing, resin molding, hot melt adhesive, or tape components can be used. In this embodiment, the insulating member 20 is a heat shrink tubing. The insulating member 20, as a heat shrink tubing, is formed into a cylindrical shape, for example, from an insulating resin material that shrinks when heated and solidifies when cooled. The insulating member 20, as a heat shrink tubing, is formed into a shape that shrinks toward the inner component by being heated and cooled.

[0034] (Composition of the shell 30) The housing 30 is formed to surround the outer periphery of the insulating member 20, the outer periphery of the first shielded wire 11, and the outer periphery of the second shielded wire 12. The housing 30 is, for example, integrally formed into a cylindrical shape. The housing 30 has an opening in a first direction X1 and an opening in a first opposite direction X2. The housing 30 is, for example, made of metal. Copper-based or aluminum-based metal materials can be used as the material for the housing 30. In this embodiment, the housing 30 is made of die-cast aluminum.

[0035] The housing 30 has a first storage portion 31 for accommodating one first shielded wire 11, a second storage portion 32 for accommodating two second shielded wires 12, and a third storage portion 33 for accommodating the core wire connection portion 15 and the insulating member 20. In the housing 30, the first storage portion 31, the third storage portion 33, and the second storage portion 32 are arranged along the X-axis. The internal spaces of the first storage portion 31, the third storage portion 33, and the second storage portion 32 are interconnected in the housing 30.

[0036] (The structure of the first storage section 31) The first receiving portion 31 extends along a first direction X1. The first receiving portion 31 is provided at the end of the housing 30 in the first direction X1. The first receiving portion 31 is formed to receive a portion of the first shielded wire 11. The first receiving portion 31 is sized to receive the end of the first shielded wire 11 in the first opposite direction X2. The first receiving portion 31 is generally formed in a cylindrical shape. The first receiving portion 31 surrounds the outer periphery of the first shielded wire 11 circumferentially.

[0037] The first storage section 31 has a connection section 34 that is electrically connected to the shielding member 11c. The connection section 34 is electrically connected to the exposed portion 11e of the shielding member 11c. like Figure 3 As shown, the connecting portion 34 is integrally formed into a cylindrical shape. The connecting portion 34 surrounds the outer periphery of the exposed portion 11e circumferentially. The connecting portion 34 is formed such that its inner peripheral surface contacts the outer peripheral surface of the exposed portion 11e. Thus, through the contact between the inner peripheral surface of the connecting portion 34 and the outer peripheral surface of the exposed portion 11e, the connecting portion 34 is electrically connected to the shielding member 11c. The inner peripheral surface of the connecting portion 34 is, for example, formed as a smooth surface.

[0038] An interference fit is provided, for example, between the inner periphery of the connecting portion 34 and the outer periphery of the exposed portion 11e. For example, the minimum inner diameter of the connecting portion 34 is set to be smaller than the maximum outer diameter of the exposed portion 11e before it is inserted into the connecting portion 34. With this setting, the exposed portion 11e of the first shielded wire 11 is fitted into the inner periphery of the connecting portion 34 with an interference fit. As a result, the inner peripheral surface of the connecting portion 34 and the outer peripheral surface of the exposed portion 11e are in contact with each other with an interference fit. That is, the exposed portion 11e fitted into the connecting portion 34 is held in a state where it is always pressed towards the radially inward side of the connecting portion 34 by the inner peripheral surface of the connecting portion 34. Therefore, the inner peripheral surface of the connecting portion 34 and the outer peripheral surface of the exposed portion 11e can be properly in contact. In this embodiment, the exposed portion 11e is pressed by the connecting portion 34, thereby connecting to the connecting portion 34 in a state where it is clamped by the connecting portion 34 and the washer ring 13. In addition, the shaking of the first shielded wire 11 can be suppressed inside the connecting portion 34.

[0039] like Figure 2 As shown, an inclined surface 35 is formed on the inner circumferential surface of the end of the first storage portion 31 in the first direction X1. The inclined surface 35 is formed to be inclined radially outward toward the opening end of the first storage portion 31 in the first direction X1. For example, the inclined surface 35 is formed to form a C-shaped chamfer at the corner of the inner circumferential surface of the first storage portion 31 and the end face of the first storage portion 31 in the first direction X1. The inclined surface 35 is formed, for example, on the entire circumference of the inner circumferential surface of the first storage portion 31.

[0040] (The composition of the second storage section 32) The second storage section 32 extends along the first direction X1. The second storage section 32 is located at the end of the housing 30 in the first opposite direction X2. The second storage section 32 has two storage tube sections 36 for storing two second shielded wires 12 respectively, and a partition wall 37 separating the two storage tube sections 36. Each storage tube section 36 is formed to store a portion of the second shielded wire 12. Each storage tube section 36 is sized to accommodate the end of the second shielded wire 12 in the first direction X1. Each storage tube section 36 is integrally formed into a cylindrical shape. Each storage tube section 36 surrounds the outer periphery of the second shielded wire 12 circumferentially. The partition wall 37 is located between the two storage tube sections 36 in the second direction Y1. The partition wall 37 is formed to separate the internal spaces of the two storage tube sections 36.

[0041] Each storage cylinder 36 has a connecting portion 38 that is electrically connected to the shielding member 12c. The connecting portion 38 is electrically connected to the exposed portion 12e of the shielding member 12c. like Figure 4As shown, the connecting portion 38 is integrally formed into a cylindrical shape. The connecting portion 38 surrounds the outer periphery of the exposed portion 12e circumferentially. The inner circumferential surface of the connecting portion 38 contacts the outer circumferential surface of the exposed portion 12e. Thus, through the contact between the inner circumferential surface of the connecting portion 38 and the outer circumferential surface of the exposed portion 12e, the connecting portion 38 is electrically connected to the shielding member 12c. The inner circumferential surface of the connecting portion 38 is, for example, formed as a smooth surface.

[0042] An interference fit is provided, for example, between the inner periphery of the connecting portion 38 and the outer periphery of the exposed portion 12e. For example, the minimum inner diameter of the connecting portion 38 is set to be smaller than the maximum outer diameter of the exposed portion 12e before it is inserted into the connecting portion 38. With this setting, the exposed portion 12e of the second shielded wire 12 is fitted into the inner periphery of the connecting portion 38 with an interference fit. As a result, the inner peripheral surface of the connecting portion 38 and the outer peripheral surface of the exposed portion 12e are in contact with each other with an interference fit. That is, the exposed portion 12e fitted into the connecting portion 38 is held in a state where it is always pressed towards the radially inward side of the connecting portion 38 by the inner peripheral surface of the connecting portion 38. Therefore, the inner peripheral surface of the connecting portion 38 and the outer peripheral surface of the exposed portion 12e can be properly in contact. In this embodiment, the exposed portion 12e is pressed by the connecting portion 38, thereby connecting to the connecting portion 38 in a state where it is clamped by the connecting portion 38 and the washer ring 13. In addition, the shaking of the second shielded wire 12 can be suppressed inside the connecting portion 38.

[0043] like Figure 2 As shown, each storage tube portion 36 has, for example, a locking wall 39. The locking wall 39 is formed, for example, to protrude radially inward from the inner circumferential surface of the connecting portion 38 toward the storage tube portion 36. The locking wall 39 is provided at the end of the storage tube portion 36 in the first opposite direction X2. The locking wall 39 is formed so that it can engage with the exposed portion 12e of the second shielded wire 12 in the axial direction of the storage tube portion 36. The locking wall 39 is formed, for example, on the entire circumferential circumference of the inner circumferential surface of the storage tube portion 36.

[0044] An inclined surface 40 is formed on the inner circumferential surface of the end face of each storage tube portion 36 in the first opposite direction X2. The inclined surface 40 is located further in the first opposite direction X2 than the engaging wall 39. The inclined surface 40 is formed to be inclined radially outward toward the storage tube portion 36 as it approaches the opening end in the first opposite direction X2. For example, the inclined surface 40 is formed to have a C-shaped chamfer at the corner of the inner circumferential surface of the storage tube portion 36 (specifically, the inner circumferential surface of the engaging wall 39) and the end face in the first opposite direction X2 of the storage tube portion 36. The inclined surface 40 is formed, for example, on the entire circumference of the inner circumferential surface of the storage tube portion 36.

[0045] (The composition of the third storage section 33) The third storage section 33 extends along the first direction X1. The third storage section 33 is disposed between the first storage section 31 and the second storage section 32 in the axial direction (X-axis direction in this embodiment) of the housing 30. The third storage section 33 has a first storage tube section 41 and a second storage tube section 42.

[0046] The first receiving tube portion 41 houses the insulating member 20 that covers one insulating cover portion 11b. The first receiving tube portion 41 also houses the insulating member 20 that covers the core wire connection portion 15. The second receiving tube portion 42 houses the insulating member 20 that covers both insulating cover portions 12b. The first receiving tube portion 41 and the second receiving tube portion 42 are integrally formed into a cylindrical shape. The first receiving tube portion 41 and the second receiving tube portion 42 completely surround the outer periphery of the insulating member 20 in the circumferential direction.

[0047] The third storage portion 33, for example, has a engaging surface 43. The engaging surface 43 is configured to engage with the insulating member 20 covering the portions of the two insulating covering portions 12b in the first direction X1. Here, the dimension of the internal space of the first storage tube portion 41 along the second direction Y1 is smaller than the dimension of the internal space of the second storage tube portion 42 along the second direction Y1. Therefore, a step is formed on the inner peripheral surface of the third storage portion 33 at the boundary between the first storage tube portion 41 and the second storage tube portion 42. Furthermore, the engaging surface 43 is formed by the surface of the inner peripheral surface of the first storage tube portion 41 facing the first opposite direction X2. In other words, the internal space of the first storage tube portion 41 is sized such that the insulating member 20 covering the portions of the two insulating covering portions 12b cannot be inserted.

[0048] like Figure 5 As shown, the housing 30 has a first partition 51 and a second partition 52 formed to be assembled with the first partition 51. The housing 30 is constructed by assembling the first partition 51 and the second partition 52. The housing 30 is formed into a cylindrical shape that surrounds the outer periphery of the first shielded wire 11, the outer periphery of the second shielded wire 12, and the outer periphery of the insulating member 20 by assembling the first partition 51 and the second partition 52. The first partition 51 and the second partition 52 are, for example, separate components. The first partition 51 and the second partition 52 have the same structure as each other. That is, the first partition 51 and the second partition 52 are components with the same product number. Therefore, in the following description, the structure of the first partition 51 will be described in detail, while the description of the structure of the second partition 52 will be omitted. Specifically, regarding the structure of the second partition 52, repeated descriptions will be omitted by changing the last "A" of the corresponding configuration of the first partition 51 to "B".

[0049] The first segment 51 is, for example, integrally formed into a semi-segmented cylindrical shape. The first segment 51, for example, has a first segmented storage portion 31A, a second segmented storage portion 32A, and a third segmented storage portion 33A. The second segment 52 is, for example, integrally formed into a semi-segmented cylindrical shape. The second segment 52, for example, has a first segmented storage portion 31B, a second segmented storage portion 32B, and a third segmented storage portion 33B. When the first segment 51 and the second segment 52 are combined, the first storage portion 31 is formed by the first segmented storage portion 31A and the first segmented storage portion 31B. When the first segment 51 and the second segment 52 are combined, the second storage portion 32A and the second segmented storage portion 32B are formed by the second storage portion 32. With the first segment 51 and the second segment 52 combined, the third storage section 33 is formed by the third segment storage section 33A and the third segment storage section 33B.

[0050] (The composition of the first segment 51) The first segment 51, for example, has a first overlapping portion 53A disposed at the circumferential end of the first segment 51. In this embodiment, the first segment 51 has two first overlapping portions 53A. The two first overlapping portions 53A are respectively disposed at the two circumferential ends of the first segment 51. Each first overlapping portion 53A protrudes radially outward from the circumferential end of the first segment 51 toward the outer side of the housing 30. The two first overlapping portions 53A protrude in opposite directions in the radial direction of the housing 30. Each first overlapping portion 53A extends, for example, along the length direction of the housing 30 (the X-axis direction in this embodiment). Each first overlapping portion 53A extends, for example, along the entire length of the housing 30.

[0051] Each of the first overlapping portions 53A has a first opposing surface 54A opposite to the second dividing body 52, and a first chamfered portion 55A at the radially outer end of the housing 30 formed in the first opposing surface 54A. The first opposing surface 54A is an end face facing the third direction Z1. The first opposing surface 54A is formed, for example, to extend parallel to the XY plane. The first opposing surface 54A extends, for example, along the entire length of the housing 30 in the length direction.

[0052] The first chamfered portion 55A is, for example, formed with a C-shaped chamfer on the corner of the radially outer end face of the first opposing surface 54A and the first overlapping portion 53A. The first chamfered portion 55A is, for example, formed to slope toward the third opposite direction Z2 as it moves away from the interior space of the housing 30. The first chamfered portion 55A extends along the entire length of the housing 30 in the longitudinal direction. The first chamfered portion 55A is also, for example, formed at the end of the housing 30 in the longitudinal direction of the first opposing surface 54A.

[0053] The first segment 51, for example, has a supply Figure 1One or more (four in this embodiment) fixing portions 56A are inserted into the bolt B1 shown. Each fixing portion 56A is provided, for example, in the first overlapping portion 53A. In the first segment 51 of this embodiment, two fixing portions 56A are provided in each first overlapping portion 53A. Each fixing portion 56A has a through hole that penetrates in the thickness direction (Z-axis direction in this embodiment) of the first overlapping portion 53A. A hole is formed on the inner peripheral surface of the fixing portion 56A that allows it to engage with the bolt B1 (see reference). Figure 1 The internal threaded portion is fastened. The fixing portion 56A is formed, for example, to protrude from the end face of the first overlapping portion 53A in the third opposite direction Z2 toward the third opposite direction Z2.

[0054] (The composition of the second segment 52) The second segment 52 has one or more (two in this embodiment) second overlapping portions 53B protruding radially outward from the circumferential end of the second segment 52 toward the housing 30. Each second overlapping portion 53B has a second opposing surface 54B opposite to the first opposing surface 54A, and a second chamfered portion 55B formed in the second opposing surface 54B at the radially outward end of the housing 30. The second segment 52 has one or more (four in this embodiment) fixing portions 56B.

[0055] like Figure 1 As shown, the first segment 51 and the second segment 52 are joined together such that the first overlapping portion 53A and the second overlapping portion 53B overlap. The housing 30 is secured to the joined state of the first segment 51 and the second segment 52, for example, by bolt B1. Bolt B1 passes through the fixing portions 56A and 56B, for example, by being screwed into the internal threads provided on the inner circumferential surfaces of the fixing portions 56A and 56B. By bolting with bolt B1 in this way, the joined state of the first segment 51 and the second segment 52 can be maintained.

[0056] like Figure 3 As shown, when the first segment 51 and the second segment 52 are combined, the first opposing surface 54A and the second opposing surface 54B overlap. The first opposing surface 54A and the second opposing surface 54B overlap each other in a direction orthogonal to the protruding direction of the first overlapping portion 53A (the Y-axis direction in this embodiment) (the Z-axis direction in this embodiment). The second opposing surface 54B is in direct contact with the first opposing surface 54A. For example, the second opposing surface 54B is in contact with the surface of the first opposing surface 54A.

[0057] With the first segment 51 and the second segment 52 combined, a groove 57 is formed by the first chamfered portion 55A and the second chamfered portion 55B. The groove 57 extends, for example, along the length of the housing 30. The groove 57 is formed such that its opening width increases along the Z-axis direction as it moves away from the interior space of the housing 30. The projected shape of the groove 57, viewed from the X-axis direction, is, for example, triangular. The groove 57 is formed, for example, on the entire circumference of the housing 30.

[0058] (Composition of adhesive 60) As the adhesive 60, for example, a thermosetting adhesive or a UV-curing adhesive can be used. In this embodiment, the adhesive 60 is a thermosetting adhesive.

[0059] like Figure 2 As shown, the adhesive 60 is formed to seal the space between the housing 30 and the first shielded wire 11. Specifically, the adhesive 60 is formed to seal the space between the inner peripheral surface of the first receiving portion 31 of the housing 30 and the outer peripheral surface of the first shielded wire 11. The adhesive 60 is formed to cover the outer peripheral surface of the first shielded wire 11 circumferentially and to cover the inner peripheral surface of the first receiving portion 31 circumferentially. The adhesive 60 is disposed at the end of the first receiving portion 31 in the first direction X1. With this adhesive 60, liquids such as water can be appropriately prevented from seeping into the interior of the housing 30 through the gap between the inner peripheral surface of the first receiving portion 31 and the outer peripheral surface of the first shielded wire 11.

[0060] Furthermore, the adhesive 60 is configured to seal the housing 30 with each of the second shielded wires 12. Specifically, the adhesive 60 is configured to seal the inner circumferential surface of each receiving tube portion 36 of the housing 30 with the outer circumferential surface of each of the second shielded wires 12. The adhesive 60 is configured to cover the outer circumferential surface of each of the second shielded wires 12 and the inner circumferential surface of each receiving tube portion 36 with the same circumferential surface. The adhesive 60 is disposed at the end of each receiving tube portion 36 in the first opposite direction X2. With this adhesive 60, liquids such as water can be appropriately prevented from seeping into the interior of the housing 30 through the gap between the inner circumferential surface of the receiving tube portion 36 and the outer circumferential surface of the second shielded wire 12.

[0061] like Figure 3 As shown, the adhesive 60 is formed, for example, to fill the groove 57. The adhesive 60 is formed on the entire circumference of the groove 57. The adhesive 60 is formed inside the groove 57, for example, so that the contact portion between the first opposing surface 54A and the second opposing surface 54B is not exposed to the outside through the groove 57. By filling the groove 57 with adhesive 60, liquids such as water can be appropriately prevented from seeping into the interior of the housing 30 through the gap between the first opposing surface 54A and the second opposing surface 54B.

[0062] Thus, the adhesive 60 of this embodiment is continuously formed on the entire circumference of the outer periphery of the housing 30. The adhesive 60 functions as a sealing member to prevent liquids such as water from seeping into the internal space of the housing 30 from the outside. In addition, the adhesive 60 filled into the groove 57 also functions as a fixing member, for example, to fix the first segment 51 and the second segment 52 into a combined state.

[0063] (Manufacturing method of wire harness 10) Next, the manufacturing method of wire harness 10 will be explained. First of all, Figure 6 In the illustrated process, a core wire connection portion 15 is formed by connecting the core wire 11a of one first shielded wire 11 and the core wires 12a of two second shielded wires 12. At this time, the exposed portion 11e of the first shielded wire 11 is folded back to surround the outer periphery of the sheath 11d. In addition, the exposed portion 12e of each second shielded wire 12 is folded back to surround the outer periphery of the sheath 12d.

[0064] Next, in Figure 7 In the process shown, an insulating member 20 is formed that covers the outer periphery of the core wire connection portion 15. For example, a heat shrink tube is arranged to surround the outer periphery of the core wire connection portion 15 before heating, and the insulating member 20 covering the outer periphery of the core wire connection portion 15 is formed by heating and cooling the heat shrink tube. Through the above process, a wire structure 70 is formed that integrates one first shielded wire 11, two second shielded wires 12, and the insulating member 20.

[0065] Next, in Figure 8 In the process shown, a first segment 51 and a second segment 52 are prepared. The first segment 51 and the second segment 52 can be formed, for example, by forming an aluminum alloy into a specified shape using known methods such as aluminum die casting.

[0066] Next, adhesive 60 is applied to the periphery of the first segment 51. Adhesive 60 is formed to continuously cover the periphery of the first segment 51. Specifically, adhesive 60 is formed to continuously cover the periphery of the first opposing surface 54A of the first segment 51. This adhesive 60 covers the first opposing surface 54A located near the first chamfered portion 55A. Additionally, adhesive 60 is formed to continuously cover the inner periphery of the first segmented storage portion 31A. This adhesive 60, for example, covers the inner periphery of the first segmented storage portion 31A located near the inclined surface 35. Adhesive 60 is formed to continuously cover the inner periphery of the storage tube portion 36 of the second segmented storage portion 32A. The adhesive 60 is, for example, formed to cover the inner periphery of the storage tube portion 36 of the second segmented storage portion 32A located near the inclined surface 40. The adhesive 60 is formed to cover the end of the partition wall 37 in the third direction Z1.

[0067] In addition, Figure 8 In the illustrated process, adhesive 60 is applied to a portion of the second segment 52. Adhesive 60 is formed to continuously cover the inner circumference of the first segment receiving portion 31B over its entire circumference. For example, adhesive 60 is formed to cover the inner circumference of the first segment receiving portion 31B located near the inclined surface 35. Adhesive 60 is formed to continuously cover the inner circumference of the second segment receiving portion 32B over its entire circumference. For example, adhesive 60 is formed to cover the inner circumference of the receiving tube portion 36 of the second segment receiving portion 32B located near the inclined surface 40.

[0068] Next, in Figure 9 In the process shown, in Figure 6 and Figure 7 The wire structure 70 manufactured in the process shown is placed on a first partition 51 coated with adhesive 60. Specifically, the wire structure 70 is placed on the first partition 51 such that the first shielded wire 11 is housed in the first partition housing 31A, each of the second shielded wires 12 is housed in the second partition housing 32A, and the insulating member 20 is housed in the third partition housing 33A. At this time, the engagement surface 43, the partition wall 37, etc., can restrict the movement of the wire structure 70 in the first direction X1 and the first opposite direction X2. Therefore, the positioning of the wire structure 70 relative to the first partition 51 can be easily achieved, and misalignment of the wire structure 70 within the first partition 51 can be appropriately suppressed.

[0069] Next, in Figure 10In the illustrated process, the second segment 52 is overlapped onto the first segment 51, on which the wire structure 70 is provided. Specifically, the first segment 51 and the second segment 52 are overlapped such that the first overlapping portion 53A and the second overlapping portion 53B overlap in the Z-axis direction, and the fixing portion 56A and the fixing portion 56B overlap in the Z-axis direction. Next, the second segment 52 is overlapped onto the first segment 51, on the second segment 52, on the third segment 52, on the fourth segment 52, on the fifth segment 52, on the sixth segment 52, on the seventh segment 52, on the eighth segment 52, on the ninth segment 52, on the eighth segment 53A, on the ninth segment 53B, on the eighth segment 52, on the ninth segment 53A, on the eighth segment 53B, on the ninth segment 54, on the ninth segment 55, on the eighth segment 56A, on the ninth segment 56B, on the ninth segment 51, on the eighth segment 52, on the ninth segment 51, on the eighth segment 51, on the ninth segment 52, on the eighth segment 51, on the ninth segment 51, on the eighth segment 52, on the ninth segment 51, on the eighth segment 52, on the ninth segment 51, on the ninth segment 52, on the eighth segment 51, on the ninth segment 52, on the eighth segment 51, on the ninth segment 52, on the eighth segment 51, on the ninth segment 52, on the eighth segment 51, on the ninth segment 52, on the eighth segment 51, on the ninth segment 52, on the ninth segment 51, on the ninth segment 52, on the eighth segment 51, on the ninth segment 52, on the ninth segment 51, on the ninth segment 52, on the eighth segment 52, on the ninth segment 51, on the ninth segment 52, Figure 1 The bolt B1 shown is screwed into the internal thread portion provided on the inner circumferential surface of the fixing parts 56A and 56B. By using bolt B1 for bolt tightening, the first segment 51 and the second segment 52 are fixed in a combined state. By such bolt tightening, the first segment 51 and the second segment 52 are tightened close to each other. Thus, as... Figure 3 As shown, the adhesive 60 applied to the first opposing surface 54A extends in the Y-axis direction, filling the groove 57 formed by the first chamfered portion 55A and the second chamfered portion 55B. Additionally, as... Figure 2 As shown, the adhesive 60 is formed to block the gap between the inner peripheral surface of the first receiving portion 31 and the outer peripheral surface of the first shielded wire 11, and to block the gap between the inner peripheral surface of the second receiving portion 32 and the outer peripheral surface of the second shielded wire 12. Then, the adhesive 60 is cured by heat treatment or the like. Furthermore, as... Figure 3 As shown, when the first segment 51 and the second segment 52 are fixed in a combined state, the inner peripheral surface of the connecting portion 34 of the first receiving portion 31 contacts the outer peripheral surface of the exposed portion 11e of the first shielded wire 11. Further, as... Figure 4 As shown, when the first segment 51 and the second segment 52 are fixed in a combined state, the inner peripheral surface of the connecting portion 38 of the second storage portion 32 contacts the outer peripheral surface of the exposed portion 12e of the second shielded wire 12.

[0070] Through the above manufacturing processes, the wire harness 10 of this embodiment can be manufactured. Next, the effects of this implementation method will be explained. (1) The wire harness 10 includes a first shielded wire 11 and a second shielded wire 12. Each of the first shielded wire 11 and the second shielded wire 12 has a core wire 11a, 12a, an insulating covering portion 11b, 12b covering the outer periphery of the core wire 11a, 12a, and a shielding member 11c, 12c covering the outer periphery of the insulating covering portion 11b, 12b. The wire harness 10 includes a core wire connecting portion 15 that connects the core wires 11a, 12a of the first shielded wire 11 and the second shielded wire 12 to each other, and an insulating member 20 covering the outer periphery of the core wire connecting portion 15. The wire harness 10 includes: a conductive housing 30 that covers the outer periphery of the insulating member 20 and covers the outer periphery of the first shielded wire 11 and the second shielded wire 12; and an adhesive 60 that seals the housing 30 with the first shielded wire 11 and the second shielded wire 12. The housing 30 has connection portions 34 and 38 that are electrically connected to each of the plurality of shielding members 11c and 12c.

[0071] According to this configuration, the outer periphery of the core wire connection portion 15 is covered by a conductive housing 30, which is electrically connected to each of the plurality of shielding members 11c and 12c. Thus, the housing 30 functions as an electromagnetic shielding member to suppress electromagnetic wave radiation from the core wire connection portion 15. Furthermore, an adhesive 60 seals the housing 30 with the first shielded wire 11 and the second shielded wire 12. Thus, the housing 30 and the adhesive 60 function as waterproof members to prevent water immersion in the core wire connection portion 15. In this way, the housing 30 functions as both an electromagnetic shielding member and a waterproof member. Therefore, compared to cases where the electromagnetic shielding member and the waterproof member are separate components, the number of components in the wire harness 10 can be reduced. As a result, the assembly steps of the wire harness 10 can be reduced, thus improving the ease of assembly of the wire harness 10.

[0072] (2) The housing 30 has a first segment 51 and a second segment 52 that are formed to be able to fit together, and a bolt B1 that fixes the first segment 51 and the second segment 52 into a fitted state. The housing 30 is formed into a cylindrical shape that surrounds the outer periphery of the insulating member 20, the outer periphery of the first shielded wire 11 and the outer periphery of the second shielded wire 12 by fitting the first segment 51 and the second segment 52 together.

[0073] According to this configuration, the housing 30 is formed into a cylindrical shape by the first dividing body 51 and the second dividing body 52, which surrounds the outer periphery of the insulating member 20, the outer periphery of the first shielded wire 11, and the outer periphery of the second shielded wire 12. Thus, although the housing 30 is formed into a cylindrical shape, it can be subsequently mounted onto the wire structure 70 by dividing the housing 30 into multiple dividing bodies, namely the first dividing body 51 and the second dividing body 52. ​​That is, the housing 30 can be mounted onto the wire structure 70 after forming the core wire connection portion 15 that connects the core wires 11a and 12a, and after forming the insulating member 20 that covers the outer periphery of the core wire connection portion 15. Therefore, the assemblability of the housing 30 relative to the wire structure 70 can be improved, and the assembly workability of the wire harness 10 can be improved.

[0074] (3) When the first segment 51 and the second segment 52 are assembled, the first opposing surface 54A of the first segment 51 and the second opposing surface 54B of the second segment 52 overlap, and a groove 57 is formed by the first chamfered portion 55A and the second chamfered portion 55B. Then, adhesive 60 is filled into the groove 57. By filling the groove 57 with adhesive 60, the first opposing surface 54A and the second opposing surface 54B can be properly sealed.

[0075] (4) The first segment 51 and the second segment 52 constituting the housing 30 are formed with the same structure. Therefore, the increase in the number of parts, or more specifically the types of parts, can be suppressed. (5) An interference fit is provided between the inner periphery of the connecting portion 34 and the outer periphery of the exposed portion 11e. According to this configuration, the exposed portion 11e of the first shielded wire 11 is fitted into the inner periphery of the cylindrical connecting portion 34 with an interference fit. That is, when the first shielded wire 11 is fitted inside the connecting portion 34, the outer peripheral surface of the exposed portion 11e and the inner peripheral surface of the connecting portion 34 are in contact with an interference fit. Therefore, the exposed portion 11e of the first shielded wire 11 fitted inside the connecting portion 34 is in contact with the inner peripheral surface of the connecting portion 34 in a state where it is always pressed radially inward by the connecting portion 34. Therefore, the inner peripheral surface of the connecting portion 34 can be properly contacted with the outer peripheral surface of the exposed portion 11e. Thus, the electrical connection reliability between the housing 30 and the shielding member 11c can be improved.

[0076] (6) An interference fit is provided between the inner periphery of the connecting portion 38 and the outer periphery of the exposed portion 12e. According to this configuration, the exposed portion 12e of the second shielded wire 12 is fitted into the inner periphery of the cylindrical connecting portion 38 with an interference fit. That is, when the second shielded wire 12 is fitted inside the connecting portion 38, the outer peripheral surface of the exposed portion 12e and the inner peripheral surface of the connecting portion 38 are in contact with each other with an interference fit. Therefore, the exposed portion 12e of the second shielded wire 12 fitted inside the connecting portion 38 is in contact with the inner peripheral surface of the connecting portion 38 in a state where it is always pressed radially inward by the connecting portion 38. Therefore, the inner peripheral surface of the connecting portion 38 and the outer peripheral surface of the exposed portion 12e can be properly contacted. Therefore, the electrical connection reliability between the housing 30 and the shielding member 12c can be improved.

[0077] (7) The exposed portions 11e and 12e are connected to the connecting portions 34 and 38 in a state where they are clamped by the gasket ring 13 and the connecting portions 34 and 38. As a result, the inner peripheral surfaces of the connecting portions 34 and 38 can make proper contact with the outer peripheral surfaces of the exposed portions 11e and 12e. Therefore, the reliability of the electrical connection between the housing 30 and the shielding members 11c and 12c can be improved.

[0078] (8) The housing 30 is made of die-cast aluminum. Based on this structure, a conductive housing 30 can be easily manufactured. (Modified example) The above-described embodiments can be implemented with the following modifications. The above-described embodiments and the following modifications can be combined and implemented with each other within the scope of technical inconsistency.

[0079] In the above embodiment, the fixing member for securing the combined state of the first segment 51 and the second segment 52 is specifically a bolt B1, but it is not limited to this. For example, the fixing member may also be a resin or metal strapping, tape, etc.

[0080] Bolt B1 in the above embodiment can also be omitted. In this case, the fixing parts 56A and 56B of the housing 30 can also be omitted. In this case, for example, the combined state of the first segment 51 and the second segment 52 can be fixed only by adhesive 60.

[0081] In the above embodiment, the sealing member is embodied in adhesive 60, but it is not limited thereto. For example, the sealing member may also be embodied in a rubber sealing member. In this case, the sealing member may not have the function of fixing the combined state of the first segment 51 and the second segment 52.

[0082] The structure of the housing 30 in the above embodiments can be appropriately modified. In the housing 30 of the above embodiment, the first partition 51 and the second partition 52 are composed of separate parts, but this is not a limitation. For example, the first partition 51 and the second partition 52 may also be formed as one piece by means of hinges or the like.

[0083] In the above embodiment, the housing 30 is composed of two segments, namely the first segment 51 and the second segment 52, but it is not limited thereto. For example, the housing 30 may also be composed of three or more segments.

[0084] In the above embodiment, the first segment 51 and the second segment 52 are formed with the same structure, but this is not a limitation. For example, the first segment 51 and the second segment 52 may also be formed with different structures. In other words, the first segment 51 and the second segment 52 may also be components with different product numbers.

[0085] The groove 57 in the housing 30 of the above embodiment may also be omitted. In this case, for example, the first chamfer 55A of the first segment 51 and the second chamfer 55B of the second segment 52 may be omitted.

[0086] In the housing 30 of the above embodiment, a locking surface 43 is provided in the third storage portion 33, but it is not limited thereto. For example, the locking surface 43 may be omitted. In this case, for example, the first storage tube portion 41 and the second storage tube portion 42 are formed to have the same dimensions along the Y-axis direction.

[0087] The inclined surface 35 in the first storage part 31 of the above embodiment can also be omitted. The inclined surface 40 in the storage tube portion 36 of the second storage portion 32 in the above embodiment can also be omitted.

[0088] In the second storage section 32 of the above embodiment, two storage tube sections 36 are provided to store the two second shielded wires 12 respectively, but this is not a limitation. For example, the second storage section 32 may be modified to store both second shielded wires 12 together. In this case, the partition wall 37 is omitted.

[0089] The gasket 13 in the above embodiments can also be omitted. In the above embodiment, core wires 11a and 12a are directly soldered, but this is not a limitation. For example, other components may be used to connect core wires 11a and 12a.

[0090] In the above embodiment, the wiring harness 10 is provided with one first shielded wire 11 and two second shielded wires 12, but it is not limited to this. For example, the number of the first shielded wire 11 and the second shielded wire 12 can be appropriately changed.

[0091] In the above embodiments, the shielding components 11c and 12c are braided wires woven into a cylindrical shape from metal wires, but are not limited to this. For example, the shielding components 11c and 12c may also be formed as metal foils made of materials such as copper alloys or aluminum alloys.

[0092] This disclosure includes the following methods. It should be noted that, in the following description, the purpose is only to aid understanding and not to limit, and the reference numerals indicating the constituent elements of the embodiments are marked with parentheses. (Note 1) A wire harness (10) comprising: Multiple shielded wires (11, 12); The core wire connecting part (15) connects the core wires (11a, 12a) of the plurality of shielded wires (11, 12) to each other; An insulating component (20) covers the outer periphery of the core wire connection portion (15); A conductive housing (30) covers the outer periphery of the insulating member (20) and also covers the outer periphery of the plurality of shielded wires (11, 12); and A sealing member (60) seals the space between the housing (30) and the plurality of shielded wires (11, 12). Each of the multiple shielded wires (11, 12) includes a shielding component (11c, 12c). The housing (30) integrally includes a plurality of cylindrical connecting parts (34, 38), which respectively surround the plurality of shielded wires (11, 12). Each of the plurality of cylindrical connecting portions (34, 38) includes an inner peripheral surface that is in contact with and electrically connected to the outer peripheral surface of the shielding member (11c, 12c) of the corresponding shielding wire among the plurality of shielding wires (11, 12). The sealing member (60) is disposed on the inner circumferential surface of the plurality of cylindrical connecting parts (34, 38) to seal the housing (30) and the plurality of shielded wires (11, 12).

[0093] According to this configuration, by housing the shielded wire within the cylindrical connecting portion, the shielding member of the shielded wire is electrically connected to the connecting portion (housing). Furthermore, a sealing member (adhesive 60 in the example of the above embodiment) provided on the inner circumferential surface of the cylindrical connecting portion allows for a seal between the connecting portion (housing) and the shielded wire. Thus, by simply placing the shielded wire within the cylindrical connecting portion, not only is an electrical connection between the housing and the shielding member achieved (electromagnetic shielding function of the housing), but also a seal between the housing and the shielded wire is achieved (waterproofing function of the housing). Therefore, both electromagnetic shielding and waterproofing functions can be achieved with a single housing, while also facilitating the assembly of multiple shielded wires into the housing.

[0094] It should be understood that the embodiments disclosed herein are illustrative in all respects and not restrictive. The scope of the invention is shown not by the foregoing meaning but by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
