[Modes for carrying out the invention]

[0010] Embodiments will be described below with reference to the drawings. In the following description, components having the same or similar function will be denoted by the same reference numerals. Duplication of these components may be omitted. In this disclosure, terms are defined as follows: “Connection” is not limited to mechanical connections but may include electrical connections. That is, “Connection” is not limited to cases where two elements to be connected are directly connected but may include cases where two elements to be connected are connected with another element interposed between them.

[0011] In this disclosure, the +X direction, -X direction, +Y direction, -Y direction, +Z direction, and -Z direction are defined as follows: The +X direction is the direction in which the end portion 21e, described later, protrudes from the insulating coating 22 of the electric wire 20 (see Figure 5). The -X direction is the direction opposite to the +X direction. When the +X direction and -X direction are not distinguished, they are simply referred to as the "X direction". The +Y direction and -Y direction are directions that intersect (e.g., orthogonal) with the X direction. The +Y direction is the direction from the first shield busbar 10A, described later, toward the second shield busbar 10B (see Figure 2). The -Y direction is the direction opposite to the +Y direction. When the +Y direction and -Y direction are not distinguished, they are simply referred to as the "Y direction". The +Z direction is the direction that intersects (e.g., orthogonal) with the X direction and the Y direction. The +Z direction is the direction from the base 60, described later, toward the cover 70 (see Figure 2). The -Z direction is the direction opposite to the +Z direction. When the +Z and -Z directions are not distinguished, they are simply referred to as the "Z direction." The X direction is an example of the "first direction." The Z direction is an example of the "second direction." The Y direction is an example of the "third direction."

[0012] (Embodiment) <1. Overall composition of the deployment unit> Figure 1 is a perspective view showing a wiring unit 1 of an embodiment. The wiring unit 1 is a component for electrically connecting multiple components (for example, multiple in-vehicle components). The wiring unit 1 includes, for example, multiple shield busbars 10, multiple electric wires 20, multiple insulating members 30 (see Figure 2), multiple shielding members 40, and connecting components 50. In this embodiment, an example of a "connecting component set AS" is formed by the multiple shielding members 40 and the connecting components 50.

[0013] <2. Shield bus bar> First, let me explain the shield busbar 10. The shield busbar 10 is a busbar having a shield structure. In this disclosure, the term "shield busbar" is used for explanatory purposes only and does not limit the scope of the invention to a specific structure.

[0014] FIG. 2 is a perspective view showing a partial breakdown of the planning unit 1. In the present embodiment, the plurality of shield busbars 10 include a first shield busbar 10A and a second shield busbar 10B. The first shield busbar 10A is an example of each of the "first busbar" and the "first planning material". The second shield busbar 10B is an example of each of the "second busbar" and the "third planning material". Hereinafter, when the first shield busbar 10A and the second shield busbar 10B are not distinguished, they are simply referred to as "shield busbar 10".

[0015] FIG. 3 is a perspective view showing an end portion 10e of the shield busbar 10. FIG. 4 is a cross-sectional view taken along line F4-F4 of the shield busbar 10 shown in FIG. 3. The shield busbar 10 includes, for example, a conductor 11, an insulating coating 12, and a shield layer 13.

[0016] <2.1 Conductor> The conductor 11 forms a conductive path through which current or a signal flows in the shield busbar 10. The conductor 11 is, for example, made of metal. The conductor 11 is, for example, a prismatic member having a flat rectangular cross-sectional shape.

[0017] As shown in FIG. 4, the conductor 11 has a first main surface 11s1, a second main surface 11s2, a first side surface 11s3, and a second side surface 11s4. The first main surface 11s1 is located at the end portion on the -Z direction side of the conductor 11. The first main surface 11s1 is a plane along the X direction and the Y direction. The second main surface 11s2 is located at the end portion on the +Z direction side of the conductor 11. The second main surface 11s2 is a plane along the X direction and the Y direction. The first side surface 11s3 is located at the end portion on the +Y direction side of the conductor 11. The first side surface 11s3 is a plane along the X direction and the Z direction. The second side surface 11s4 is located at the end portion on the -Y direction side of the conductor 11. The second side surface 11s4 is a plane along the X direction and the Z direction. In the present embodiment, the first main surface 11s1 and the second main surface 11s2 are larger than the first side surface 11s3 and the second side surface 11s4.

[0018] As shown in FIG. 3, the conductor 11 has an end portion 11e as an end portion on the -X direction side. The end portion 11e protrudes in the -X direction from the end portion 12e of the insulating film 12 described later. The end portion 11e is not covered with the insulating film 12 and the shield layer 13 and is exposed outside the shield bus bar 10. The end portion 11e is an example of a "conductor end portion".

[0019] <2.2 Insulating Film> The insulating film 12 is an insulating member that covers the outer periphery of the conductor 11. The insulating film 12 is made of, for example, a synthetic resin. The insulating film 12 covers the outer periphery of the conductor 11 having, for example, a flat rectangular cross-sectional shape so as to surround the entire circumference of the cross-sectional shape. The insulating film 12 has an end portion 12e as an end portion on the -X direction side. The end portion 12e of the insulating film 12 is not covered with the shield layer 13 and is exposed outside the shield bus bar 10.

[0020] <2.3 Shield Layer> The shield layer 13 is a shield portion that covers the outer periphery of the insulating film 12. The shield layer 13 is, for example, a shield portion for noise reduction. The shield layer 13 is a braid, a mesh structure, a metal foil, or the like, but is not limited thereto. In this embodiment, the shield layer 13 is integrated with the conductor 11 and the insulating film 12. The shield layer 13 covers the outer periphery of the insulating film 12 so as to surround the entire circumference of the cross-sectional shape for a conductor 11 having, for example, a flat rectangular cross-sectional shape.

[0021] As shown in FIG. 4, the shield layer 13 has a first main surface portion 13s1, a second main surface portion 13s2, a first side surface portion 13s3, and a second side surface portion 13s4.

[0022] The first main surface portion 13s1 is located at an end portion on the -Z direction side in the shield layer 13. The first main surface portion 13s1 is a flat portion along the X direction and the Y direction. The first main surface portion 13s1 is a flat portion along the first main surface 11s1 of the conductor 11.

[0023] The second main surface portion 13s2 is located at the +Z direction end of the shield layer 13. The second main surface portion 13s2 is a flat portion along the X and Y directions. The second main surface portion 13s2 is a flat portion along the second main surface 11s2 of the conductor 11.

[0024] The first side portion 13s3 is located at the +Y direction end of the shield layer 13. The first side portion 13s3 is a flat portion along the X and Z directions. The first side portion 13s3 is a flat portion along the first side portion 11s3 of the conductor 11.

[0025] The second side portion 13s4 is located at the -Y direction end of the shield layer 13. The second side portion 13s4 is a flat portion along the X and Z directions. The second side portion 13s4 is a flat portion along the second side portion 11s4 of the conductor 11.

[0026] In this disclosure, the term "flat area" is not limited to a flat area in the strict sense, but may include areas that can be considered flat when viewed macroscopically. For example, areas that have small steps, depressions, or voids formed by braiding or mesh structures may also be considered examples of "flat areas" as defined in this disclosure.

[0027] The shield layer 13 has an end 13e as its -X-direction end. The end 13e of the shield layer 13 is located on the +X-direction side compared to the end 12e of the insulating coating 12. The shield layer 13 is exposed to the outside of the shield busbar 10.

[0028] <2.4 Shape of Shield Busbars> In this embodiment, the shield busbar 10 has an end 10e as the end on the +X direction side. The end 10e of the shield busbar 10 includes, for example, the end 11e of the conductor 11, the end 12e of the insulating coating 12, and the end 13e of the shield layer 13. In this embodiment, the end 10e of the shield busbar 10 extends linearly in the X direction.

[0029] <2.5 Arrangement Structure of Two Shielded Busbars> As shown in Figure 2, the first shield busbar 10A and the second shield busbar 10B are arranged side by side in the Y direction. The first shield busbar 10A and the second shield busbar 10B are arranged side by side in the Y direction, for example, with their shorter sides, which are included in the flattened rectangular cross-sectional shape of the conductor 11, facing each other.

[0030] Furthermore, in this disclosure, "the first busbar and the second busbar are aligned in the Y direction" is not limited to cases where the first busbar and the second busbar are aligned in the Y direction along their entire lengths, but may also include cases where a portion of the first busbar (e.g., the -X direction end 10e) and a portion of the second busbar (e.g., the -X direction end 10e) are aligned in the Y direction, but another portion of the first busbar and another portion of the second busbar are not aligned in the Y direction. This definition also applies to the first wire 20A and the second wire 20B described later.

[0031] <3.Electric wire> Next, I will explain the electric wire 20. As shown in Figure 2, the multiple wires 20 include a first wire 20A and a second wire 20B. The first wire 20A is an example of a "second wiring material". The second wire 20B is an example of a "fourth wiring material". Hereafter, when the first wire 20A and the second wire 20B are not distinguished, they will simply be referred to as "wire 20". The wire 20 includes, for example, a core wire 21 and an insulating coating 22 (see Figure 5).

[0032] <3.1 Core Wire> Figure 5 is a cross-sectional view along the F5-F5 line of the wiring unit 1 shown in Figure 1. The core wire 21 forms a conductive path through which current or signals flow in the electric wire 20. The core wire 21 is, for example, made of metal. The core wire 21 is, for example, cylindrical. The core wire 21 has an end 21e as the end on the +X direction side. The end 21e protrudes in the +X direction from the end 22e of the insulating coating 22, which will be described later. The end 21e is not covered by the insulating coating 22 and is exposed to the outside of the insulating coating 22. The end 21e is an example of a "core wire end".

[0033] The end 21e of the core wire 21 has a flat portion 21p formed, for example, by crushing the end 21e. The end 11e of the conductor 11 of the shield busbar 10 and the flat portion 21p of the end 21e of the core wire 21 are overlapped in the Z direction. The end 11e of the conductor 11 of the shield busbar 10 and the flat portion 21p of the end 21e of the core wire 21 are then joined together. This joining connects the conductor 11 of the shield busbar 10 and the core wire 21 of the electric wire 20 both physically and electrically. The joining method is, for example, ultrasonic welding or resistance welding, but is not limited to these examples.

[0034] <3.2 Insulating Coating> The insulating coating 22 is an insulating member that covers the outer circumference of the core wire 21. The insulating coating 22 is made of, for example, synthetic resin. The insulating coating 22 covers the outer circumference of the core wire 21 so as to surround its entire circumference. The insulating coating 22 has an end 22e as the end on the +X direction side.

[0035] <3.3 Arrangement Structure of Two Electrical Wires> As shown in Figure 2, the first wire 20A and the second wire 20B are arranged side by side in the Y direction. In this embodiment, the end 11e of the conductor 11 of the first shield busbar 10A is joined to the end 21e of the core wire 21 of the first wire 20A. Also, the end 11e of the conductor 11 of the second shield busbar 10B is joined to the end 21e of the core wire 21 of the second wire 20B.

[0036] <4. Insulating materials> Next, the insulating member 30 will be described. As shown in Figure 2, the multiple insulating members 30 include a first insulating member 30A and a second insulating member 30B. Hereafter, when the first insulating member 30A and the second insulating member 30B are not distinguished, they will simply be referred to as "insulating member 30".

[0037] As shown in Figure 5, the insulating member 30 is a member that insulates and protects the end 11e of the conductor 11 of the shield busbar 10 and the end 21e of the core wire 21 of the electric wire 20 from the outside. The insulating member 30 is provided in the X direction, extending from the end 12e of the insulating coating 12 of the shield busbar 10 to the end 22e of the insulating coating 22 of the electric wire 20. The insulating member 30 is, for example, cylindrical. The insulating member 30 covers the outer circumference of the end 11e of the conductor 11 of the shield busbar 10 and also covers the outer circumference of the end 21e of the core wire 21 of the electric wire 20. The insulating member 30 is, for example, a hot-melt-filled heat-shrinkable tube.

[0038] In this embodiment, the first insulating member 30A is attached to the connection between the first shield busbar 10A and the first electric wire 20A. On the other hand, the second insulating member 30B is attached to the connection between the second shield busbar 10B and the second electric wire 20B.

[0039] <5. Shielding material> Next, the shield member 40 will be described. As shown in Figure 2, the multiple shield members 40 include a first shield member 40A and a second shield member 40B. Hereafter, when the first shield member 40A and the second shield member 40B are not distinguished, they will simply be referred to as "shield member 40".

[0040] As shown in Figure 5, the shielding member 40 is an outer covering member attached to the electric wire 20. The shielding member 40 is, for example, an outer covering member for noise reduction. The shielding member 40 is, for example, a sheet-type corrugated tube having a shielding layer 41.

[0041] The shield member 40 includes, for example, a shield layer 41 and an outer covering material 42. The shield layer 41 is, for example, a sheet. The shield layer 41 is, for example, a nonwoven fabric with metal plating. The outer covering material 42 is, for example, a mesh structure provided on the outer surface of the shield layer 41. The outer covering material 42 is, for example, a metal-plated material. The shield member 40 is rolled into a cylindrical shape and attached to surround the entire circumference of the electric wire 20.

[0042] In this embodiment, the shield member 40 extends beyond the end 21e of the core wire 21 of the electric wire 20 toward the +X direction so as to cover the outer circumference of the end 10e of the shield busbar 10 in addition to the outer circumference of the electric wire 20. The shield member 40 has a main body portion 45 that covers the outer circumference of the electric wire 20 and an end portion 46 that covers the outer circumference of the end 10e of the shield busbar 10 (for example, the outer circumference of the end 13e of the shield layer 13). The main body portion 45 is an annular shape that follows the outer circumference of the cylindrical electric wire 20. The main body portion 45 is an example of the "first portion". The end portion 46 is a flat rectangular annular shape that follows the outer circumference of the end 10e of the flat rectangular prism-shaped shield busbar 10. The end portion 46 is an example of the "second portion".

[0043] In this embodiment, the first shield member 40A covers the outer circumference of the first electric wire 20A and the outer circumference of the end portion 10e of the first shield busbar 10A. The second shield member 40B covers the outer circumference of the second electric wire 20B and the outer circumference of the end portion 10e of the second shield busbar 10B.

[0044] Figure 6 is a cross-sectional view of the shielding unit 1 shown in Figure 5 along the line F6-F6. The end portion 46 of the shield member 40 includes a flat portion 46s1 and a flat portion 46s2.

[0045] The flat portion 46s1 is located at the -Z direction end of the shield member 40. The flat portion 46s1 is a flat portion that runs along the X and Y directions. The flat portion 46s1 is a flat portion that runs along the first main surface portion 13s1 of the shield layer 13 of the shield busbar 10.

[0046] The flat portion 46s2 is located at the +Z direction end of the shield member 40. The flat portion 46s2 is a flat portion that runs along the X and Y directions. The flat portion 46s2 is a flat portion that runs along the second main surface portion 13s2 of the shield layer 13 of the shield busbar 10.

[0047] As stated above, the term "flat area" in this disclosure is not limited to a plane in the strict sense, but may include areas that can be considered flat when viewed macroscopically. For example, even if the exterior material 42 is formed by braiding or a mesh structure and has small steps, depressions, or voids, it may still be considered an example of a "flat area" as defined in this disclosure.

[0048] Hereinafter, the assembly formed by assembling the first shield busbar 10A, the first electric wire 20A, the first insulating member 30A, and the first shield member 40A will be referred to as the first conduit assembly CA1. Similarly, the assembly formed by assembling the second shield busbar 10B, the second electric wire 20B, the second insulating member 30B, and the second shield member 40B will be referred to as the second conduit assembly CA2.

[0049] <6. Connecting Components> Next, let's return to Figure 2 and explain the connecting component 50. The connecting component 50 is a component that presses the shield member 40 toward the shield layer 13 of the shield busbar 10. The connecting component 50 has, for example, a base 60, a cover 70, and a pressing portion 80 (see Figure 5).

[0050] <6.1 Base> The base 60 is a member facing the first guideway assembly CA1 and the second guideway assembly CA2 from the -Z direction. The base 60 is an example of the "first member". The base 60 is formed of an insulating material such as synthetic resin. The base 60 includes, for example, a first main wall portion 61, a first side wall portion 62, a second side wall portion 63, and an upright wall portion 64. The base 60 is open on the +Z direction side.

[0051] (1st main wall) The first main wall portion 61 is a wall portion that faces the first guideway assembly CA1 and the second guideway assembly CA2 from the -Z direction. The first main wall portion 61 includes a first region R1 and a second region R2. The first region R1 faces the first guideway assembly CA1 from the -Z direction. The first housing portion S1 is the space in the connecting component 50 where the first guideway assembly CA1 is arranged. The second region R2 faces the second guideway assembly CA2 from the -Z direction. The second housing portion S2 is the space in the connecting component 50 where the second guideway assembly CA2 is arranged.

[0052] In this embodiment, the first region R1 has, for example, a first portion 61a, a second portion 61b, and a third portion 61c.

[0053] The first portion 61a faces a part of the first shield busbar 10A from the -Z direction in an area that is separate from the first shield member 40A when viewed from the Z direction. The first portion 61a is a flat wall portion along the X and Y directions. The first portion 61a is along the first main surface portion 13s1 of the shield layer 13 of the first shield busbar 10A.

[0054] The second portion 61b is located on the -X side of the first portion 61a. The second portion 61b faces the end 46 of the first shield member 40A from the -Z direction. The second portion 61b is a flat wall portion along the X and Y directions. The second portion 61b is along the flat portion 46s1 of the first shield member 40A.

[0055] The second portion 61b is positioned offset to the -Z direction relative to the first portion 61a so that the first housing portion S1 expands to the -Z direction. As a result, a stepped portion ST1 in the Z direction is formed at the boundary between the first portion 61a and the second portion 61b. The stepped portion ST1 extends in the Y direction at a position corresponding to the +X direction end 46ea of ​​the first shield member 40A. Positioning of the first guideway assembly CA1 (for example, positioning of the first shield member 40A) can be done, for example, by aligning the +X direction end 46ea of ​​the first shield member 40A along the stepped portion ST1.

[0056] The third portion 61c is located on the -X side of the second portion 61b. The third portion 61c faces a part of the main body 45 of the first shield member 40A from the -Z direction. The third portion 61c is arc-shaped and follows the outer shape of the main body 45 of the first shield member 40A. The third portion 61c is integrated with the first side wall portion 62 and the upright wall portion 64, which will be described later.

[0057] The third portion 61c bulges in the -Z direction relative to the second portion 61b so that the first housing portion S1 expands in the -Z direction. As a result, a stepped portion ST2 in the Z direction is formed at the boundary between the second portion 61b and the third portion 61c. The stepped portion ST2 is provided at a position corresponding to the boundary between the main body portion 45 and the end portion 46 of the first shield member 40A. Positioning of the first guideway assembly CA1 (for example, positioning of the first shield member 40A) can be done, for example, by aligning the boundary between the main body portion 45 and the end portion 46 of the first shield member 40A along the stepped portion ST2.

[0058] In this embodiment, the second region R2 has a first portion 61a, a second portion 61b, and a third portion 61c, similar to the first region R1. Details regarding the second region R2 can be found by replacing "first shield busbar 10A" with "second shield busbar 10B" and "first shield member 40A" with "second shield member 40B" in the description above regarding the first region R1.

[0059] (First side wall section) The first side wall portion 62 is a wall portion that protrudes in the +Z direction from the -Y direction end of the first main wall portion 61.

[0068] (Standing wall) The upright wall portion 74 is a wall portion that protrudes in the -Z direction from the center of the second main wall portion 71 in the Y direction. The upright wall portion 74 is located between the third region R3 and the fourth region R4 of the second main wall portion 71. The upright wall portion 74 extends along the X and Z directions. The upright wall portion 74 forms part or all of the insulating wall WI. In this embodiment, the insulating wall WI is formed by the combination of the upright wall portion 74 of the cover 70 and the upright wall portion 64 of the base 60. Alternatively, the insulating wall WI may be formed by the upright wall portion 64 of the base 60 alone, or by the upright wall portion 74 of the cover 70 alone.

[0069] <6.3 Pressing Section> The pressing portion 80 is the part that presses the end 46 of the shield member 40 toward the end 13e of the shield layer 13 of the shield busbar 10 when the base 60 and the cover 70 are assembled. The pressing portion 80 is provided on at least one of the base 60 and the cover 70.

[0070] As shown in Figure 5, in this embodiment, the pressing portion 80 has, for example, a first protrusion 81, a second protrusion 82, a third protrusion 83, and a fourth protrusion 84.

[0071] (1st protrusion) The first projection 81 is provided on the second portion 61b of the first main wall portion 61 of the base 60. The first projection 81 is provided at a position that overlaps with the end portion 46 of the shield member 40 (a position that overlaps with the end portion 13e of the shield layer 13 of the shield busbar 10) when viewed from the Z direction. The first projection 81 protrudes in the +Z direction from the inner surface 61s1 of the second portion 61b of the first main wall portion 61. When the base 60 and the cover 70 are assembled (for example, engaged), the first projection 81 contacts the end portion 46 of the shield member 40 from the -Z direction side and presses the end portion 46 of the shield member 40 toward the end portion 13e of the shield layer 13 of the shield busbar 10. When the end portion 46 of the shield member 40 is pressed toward the end portion 13e of the shield layer 13 of the shield busbar 10, the end portion 46 of the shield member 40 and the end portion 13e of the shield layer 13 make sure contact. When the end portion 46 of the shield member 40 and the end portion 13e of the shield layer 13 are in secure contact, the electrical connection between the end portion 46 of the shield member 40 and the end portion 13e of the shield layer 13 becomes stable.

[0072] As shown in Figure 6, the first projection 81 is a rib that extends in the Y direction with a constant height relative to the inner surface 61s1 of the first main wall 61. When viewed from the Z direction, the first projection 81 overlaps the flat portion 46s1 of the end 46 of the shield member 40 and the first main surface portion 13s1 of the shield layer 13 of the shield busbar 10. When the base 60 and the cover 70 are assembled (for example, engaged), the first projection 81 presses the flat portion 46s1 of the end 46 of the shield member 40 toward the first main surface portion 13s1 of the shield layer 13 of the shield busbar 10.

[0073] In this embodiment, the first protrusion 81 is provided in the first main wall portion 61 of the base 60, in both the first region R1 and the second region R2. The first protrusion 81 provided in the first region R1 presses the flat portion 46s1 of the end portion 46 of the first shield member 40A toward the first main surface portion 13s1 of the shield layer 13 of the first shield busbar 10A. On the other hand, the first protrusion 81 provided in the second region R2 presses the flat portion 46s1 of the end portion 46 of the second shield member 40B toward the first main surface portion 13s1 of the shield layer 13 of the second shield busbar 10B.

[0074] (Second protrusion) As shown in Figure 5, the second projection 82 is provided on the second portion 71b of the second main wall portion 71 of the cover 70. The second projection 82 is provided at a position that overlaps with the end portion 46 of the shield member 40 when viewed from the Z direction (a position that overlaps with the end portion 13e of the shield layer 13 of the shield busbar 10). The second projection 82 is positioned, for example, opposite the first projection 81 in the Z direction. The second projection 82 protrudes in the -Z direction from the inner surface 71s1 of the second portion 71b of the second main wall portion 71. When the base 60 and the cover 70 are assembled (for example, engaged), the second projection 82 contacts the end portion 46 of the shield member 40 from the +Z direction side and presses the end portion 46 of the shield member 40 toward the end portion 13e of the shield layer 13 of the shield busbar 10. When the end portion 46 of the shield member 40 is pressed toward the end portion 13e of the shield layer 13 of the shield busbar 10, the end portion 46 of the shield member 40 and the end portion 13e of the shield layer 13 come into secure contact. As described above, when the end portion 46 of the shield member 40 and the end portion 13e of the shield layer 13 come into secure contact, the electrical connection between the end portion 46 of the shield member 40 and the end portion 13e of the shield layer 13 becomes stable. In this embodiment, the end portion 46 of the shield member 40 is held between the first projection 81 and the second projection 82 from both sides in the Z direction.

[0075] As shown in Figure 6, the second projection 82 is a rib that extends in the Y direction with a constant height relative to the inner surface 71s1 of the second main wall 71. When viewed from the Z direction, the second projection 82 overlaps the flat portion 46s2 of the end 46 of the shield member 40 and the second main surface portion 13s2 of the shield layer 13 of the shield busbar 10. When the base 60 and the cover 70 are assembled (for example, engaged), the second projection 82 presses the flat portion 46s2 of the end 46 of the shield member 40 toward the second main surface portion 13s2 of the shield layer 13 of the shield busbar 10.

[0076] In this embodiment, the second protrusion 82 is provided in the second main wall portion 71 of the cover 70, in both the third region R3 and the fourth region R4. The second protrusion 82 provided in the third region R3 presses the flat portion 46s2 of the end portion 46 of the first shield member 40A toward the second main surface portion 13s2 of the shield layer 13 of the first shield busbar 10A. On the other hand, the second protrusion 82 provided in the fourth region R4 presses the flat portion 46s2 of the end portion 46 of the second shield member 40B toward the second main surface portion 13s2 of the shield layer 13 of the second shield busbar 10B.

[0077] (3rd protrusion) The third projection 83 is provided on the first main wall portion 61 of the base 60. The third projection 83 is positioned so as to overlap with the main body portion 45 of the shield member 40 when viewed from the Z direction. The third projection 83 protrudes in the +Z direction from the inner surface 61s1 of the first main wall portion 61 of the base 60. When the base 60 and the cover 70 are assembled (for example, engaged), the third projection 83 contacts the main body portion 45 of the shield member 40 from the -Z direction side. When the third projection 83 contacts the main body portion 45 of the shield member 40, the main body portion 45 of the shield member 40 is held stably.

[0078] (4th protrusion) The fourth projection 84 is provided on the second main wall portion 71 of the cover 70. The fourth projection 84 is positioned so as to overlap with the main body portion 45 of the shield member 40 when viewed from a certain direction. The fourth projection 84 protrudes in the -Z direction from the inner surface 71s1 of the second main wall portion 71 of the cover 70. When the base 60 and the cover 70 are assembled (for example, engaged), the fourth projection 84 contacts the main body portion 45 of the shield member 40 from the +Z direction side. When the fourth projection 84 contacts the main body portion 45 of the shield member 40, the main body portion 45 of the shield member 40 is held stably.

[0079] <7. Additional waterproofing treatment> In addition to the configuration described above, the connecting component 50 may also have a waterproof section WP (see Figure 5). The waterproof section WP is a waterproofed portion that suppresses corrosion of the connection between the conductor 11 of the shield busbar 10 and the core wire 21 of the electric wire 20. The waterproof section WP is formed between the base 60 and the cover 70 by injecting potting material between the base 60 and the cover 70. For example, the waterproof section WP is formed by injecting potting material between the base 60 and the cover 70 through an injection hole 91 provided in the base 60 or the cover 70.

[0080] <8. Assembly method for distribution unit 1> Next, we will explain how to assemble the wiring unit 1. Figure 7 is a diagram illustrating the assembly method of the wiring unit 1. First, the end 11e of the conductor 11 of the first shield busbar 10A is joined to the end 21e of the core wire 21 of the first electric wire 20A. Then, the end 11e of the conductor 11 of the second shield busbar 10B is joined to the end 21e of the core wire 21 of the second electric wire 20B (see (a) in Figure 7).

[0081] Next, the insulating members 30 are attached. For example, the first insulating member 30A, before heat shrinkage, is attached to the connection between the first shield busbar 10A and the first wire 20A. Also, the second insulating member 30B, before heat shrinkage, is attached to the connection between the second shield busbar 10B and the second wire 20B. Then, a heat treatment is performed to cause the first insulating member 30A and the second insulating member 30B to shrink (see (b) in Figure 7). This process ensures insulation at the connection between the first shield busbar 10A and the first wire 20A, and at the connection between the second shield busbar 10B and the second wire 20B.

[0082] Next, the shield members 40 are attached. For example, the first shield member 40A is provided so as to cover the outer circumference of the end 10e of the first shield busbar 10A and the outer circumference of the first electric wire 20A. The second shield member 40B is also attached so as to cover the outer circumference of the end 10e of the second shield busbar 10B and the outer circumference of the second electric wire 20B (see (c) in Figure 7). This completes the assembly of the first guideway assembly CA1 and the second guideway assembly CA2.

[0083] Next, the connecting parts 50 are attached. For example, with the base 60 and the cover 70 separated, the first guideway assembly CA1 and the second guideway assembly CA2 are placed inside the base 60. Next, the cover 70 is combined with the base 60 (see (d) in Figure 7). When the cover 70 is combined with the base 60, the first projection 81 and the second projection 82 each press the end 46 of the first shield member 40A toward the end 13e of the shield layer 13 of the first shield busbar 10A, and the end 46 of the second shield member 40B toward the end 13e of the shield layer 13 of the second shield busbar 10B.

[0084] <9. Advantages> In a configuration where a busbar having a shielding layer is connected to a wire with a shielding member, the process of electrically connecting the shielding layer and the shielding member may become complicated.

[0085] On the other hand, in this embodiment, a shielding member 40 is provided. The shielding member 40 includes a main body portion 45 that covers the outer circumference of the insulating coating 22 of the electric wire 20, and an end portion 46 that covers the outer circumference of the end portion 13e of the shielding layer 13 of the shield busbar 10. The connecting component 50 has a base 60, a cover 70, and a pressing portion 80. The base 60 faces the shielding member 40 from the Z direction. The cover 70 is positioned on the opposite side of the shielding member 40 from the base 60 and is combined with the base 60. When the base 60 and the cover 70 are combined, the pressing portion 80 presses the end portion 46 of the shielding member 40 toward the end portion 13e of the shielding layer 13. With this configuration, the pressing portion 80 presses the end portion 46 of the shielding member 40 toward the end portion 13e of the shielding layer 13, making it easy to electrically connect the shielding member 40 and the shielding layer 13. This improves work efficiency.

[0086] In this embodiment, the shield member 40 is a sheet-type corrugated tube having a shield layer 41. With this configuration, the shield member 40, which is a sheet-type corrugated tube, can be easily connected to the shield layer 13 of the shield busbar 10.

[0087] In this embodiment, the pressing portion 80 is provided on the base 60 or cover 70 and includes a projection 81 or projection 82 that presses the end 46 of the shield member 40 toward the end 13e of the shield layer 13. With this configuration, the end 46 of the shield member 40 can be pressed toward the end 13e of the shield layer 13 more reliably by the projection 81 or projection 82.

[0088] In this embodiment, the shield member 40 has a flat portion 46s1 or flat portion 46s2 along the main surface portion 13s1 or second main surface portion 13s2 of the shield layer 13. The protrusion 81 or protrusion 82 is a rib extending in the Y direction. The protrusion 81 or protrusion 82 presses the flat portion 46s1 or flat portion 46s2 of the shield member 40 toward the first main surface portion 13s1 or second main surface portion 13s2 of the shield layer 13. With this configuration, the contact area between the shield member 40 and the shield layer 13 can be increased by utilizing the structure having the flat portion 46s1 or flat portion 46s2.

[0089] In this embodiment, at least one of the base 60 and the cover 70 has a stepped portion ST1 provided at a position corresponding to the X-direction end 46ea of ​​the shield member 40, which restricts the position of the shield member 40 in the X-direction. With this configuration, the base 60 or the cover 70 can position the shield member 40 in the X-direction and / or suppress misalignment.

[0090] In this embodiment, when the base 60 and the cover 70 are assembled, the pressing portion 80 presses the end 46 of the first shield member 40A toward the end 13e of the shield layer 13 of the first shield busbar 10A, and also presses the end 46 of the second shield member 40B toward the end 13e of the shield layer 13 of the second shield busbar 10B. With this configuration, the process of assembling the base 60 and the cover 70 allows for the simultaneous electrical connection of multiple pairs of shield members 40 and shield layers 13.

[0091] <10. Variation> Next, a modified example of the embodiment will be described. Note that, apart from the configuration described below, the configuration is the same as that of the embodiment described above.

[0092] Figure 8 shows a cross-section of a modified shielding unit 1. In this modified example, the shield member 40 includes a braided or mesh structure and has multiple recesses or voids. For example, the exterior material 42 of the shield member 40 is a braided or mesh structure and has multiple recesses or voids.

[0093] In this modified example, at least one of the base 60 and the cover 70 includes a plurality of projections 101. The plurality of projections 101 protrude from the first main wall portion 61 or the second main wall portion 71 toward the end portion 46 of the shield member 40. The plurality of projections 101 are arranged at equal intervals, for example, in the X and Y directions. The plurality of projections 101 engage with the end portion 46 of the shield member 40 from the Z direction.

[0094] In this modified example, the multiple protrusions 101 are provided on the second portion 61b of the first main wall portion 61 of the base 60, or on the second portion 71b of the second main wall portion 71 of the cover 70. The multiple protrusions 101 include two or more protrusions 101 that are positioned at different locations with respect to the Y direction. In this disclosure, "positioned at different locations with respect to the Y direction" is not limited to being aligned in the Y direction, but may also include being positioned at obliquely offset locations with respect to the Y direction. The two or more protrusions 101 engage with the flat portion 46s1 or flat portion 46s2 of the end portion 46 of the shield member 40 from the Z direction.

[0095] As described above, in this modified example, the connecting component 50 has a plurality of protrusions 101 that bite into the end portion 46 of the shield member 40. With this configuration, the plurality of protrusions 101 can be used to position the first guideway assembly CA1 and the second guideway assembly CA2, and / or to suppress misalignment.

[0096] In this modified example, two or more protrusions 101 positioned at different locations in the Y direction engage with the flat portion 46s1 or flat portion 46s2 of the end portion 46 of the shield member 40. With this configuration, the positioning of the first guideway assembly CA1 and the second guideway assembly CA2, and the suppression of misalignment, can be more firmly achieved by utilizing the configuration of the shield member 40 having the flat portion 46s1 or flat portion 46s2.

[0097] If we were to provide two or more protrusions as described above on a base or cover corresponding to a cylindrical shielded cable, all the protrusions would have to be directed towards the center of the conductor. In this case, an undercut problem would occur during the molding of the base or cover, making it difficult to provide such protrusions. On the other hand, in this embodiment, the structure of the base 60 or cover 70 corresponding to the shielded busbar 10 is used to provide the protrusion 101, making it easier to form the protrusion 101.

[0098] Furthermore, the multiple protrusions 101 may engage with the main body portion 45 of the shield member 40 instead of the end portion 46 of the shield member 40. Alternatively, the multiple protrusions 101 may engage with the shield layer 13 of the shield busbar 10 instead of / in addition to the shield member 40. Even with a configuration in which the multiple protrusions 101 engage with the shield layer 13, the positioning of the first guideway assembly CA1 and the second guideway assembly CA2, and / or suppression of misalignment, can be achieved.

[0099] Embodiments and several modifications have been described above. However, embodiments and modifications are not limited to the examples described above. For example, the modifications may be implemented in combination with each other. For example, in the embodiment described above, the engaging portions 65 and 66 of the base 60 were claws, and the engaging portions 75 and 76 of the cover 70 were engaging holes. Alternatively, the engaging portions 75 and 76 of the cover 70 may be claws, and the engaging portions 65 and 66 of the base 60 may be engaging holes. [Explanation of Symbols]
