[0008] [Description of Embodiments in this Disclosure] First, embodiments of this disclosure will be listed and described. [1] The wire harness of the present disclosure includes an electric wire, a terminal connected to the end of the electric wire in a first direction, a terminal cover housing the terminal, a first electromagnetic shielding member surrounding the outer circumference of the electric wire, a second electromagnetic shielding member surrounding the outer circumference of the electric wire exposed from the first electromagnetic shielding member and surrounding the outer circumference of the terminal cover, a first fixing member fixing the second electromagnetic shielding member to the outer circumference of the terminal cover, and a connecting member electrically connecting the first electromagnetic shielding member and the second electromagnetic shielding member, wherein the second electromagnetic shielding member has a first end and a second end, the second end surrounding the outer circumference of the first electromagnetic shielding member and electrically connected to the first electromagnetic shielding member by the connecting member.

[0009] In this configuration, the outer circumference of the wire exposed from the first electromagnetic shielding member is surrounded by the second electromagnetic shielding member, which is electrically connected to the first electromagnetic shielding member, and the outer circumference of the terminal cover is also surrounded. As a result, the wire exposed from the first electromagnetic shielding member and the wire housed inside the terminal cover can be electromagnetically shielded by the second electromagnetic shielding member. Consequently, the degradation of the electromagnetic shielding performance in the wire exposed from the first electromagnetic shielding member can be effectively suppressed.

[0010] [2] In [1] above, it further has a second fixing member for fixing the first end portion to the outer periphery of the electric wire. The first end portion is provided at a position facing in a first opposite direction, which is the opposite direction of the first direction from the terminal cover. The second electromagnetic shielding member has a folded-back portion that is folded back from a position facing in the first direction from the first fixing member toward the first electromagnetic shielding member. The folded-back portion surrounds the outer periphery of the first fixing member, and the tip end portion of the folded-back portion may be the second end portion.

[0011] According to this configuration, a part of the outer periphery of the terminal cover and a part of the outer periphery of the electric wire are doubly surrounded by the region from the first end portion to the folded-back portion of the second electromagnetic shielding member and the folded-back portion of the second electromagnetic shielding member. Thereby, the electric wire exposed from the first electromagnetic shielding member can be stably electromagnetic shielded by the second electromagnetic shielding member having the folded-back portion.

[0012] [3] In [2] above, the first end portion may be provided at a position facing in the first direction from the end portion of the first electromagnetic shielding member. According to this configuration, the first end portion of the second electromagnetic shielding member is fixed to the outer periphery of the electric wire by the second fixing member at a position where it does not overlap with the first electromagnetic shielding member. Thereby, since the first end portion of the second electromagnetic shielding member can be directly fixed to the outer periphery of the electric wire, the first end portion of the second electromagnetic shielding member can be stably fixed to the outer periphery of the electric wire.

[0013] [4] In any one of [1] to [3] above, the terminal cover has a fixing portion to which the second electromagnetic shielding member is fixed by the first fixing member. The fixing portion is provided at an intermediate position in the axial direction of the terminal cover, and the outer peripheral surface of the fixing portion may be formed in a groove shape.

[0014] According to this configuration, the outer peripheral surface of the fixing portion is formed in a groove shape. Therefore, even when the first fixing member is attached to the fixing portion, it is possible to suitably suppress an increase in the size of the entire wire harness.

[0015] [5] In [4] above, the first fixing member may include a tape member that covers the outer peripheral surface of the second electromagnetic shielding member, and a fixing ring attached to the outer periphery of the fixing portion so as to surround the outer periphery of the tape member.

[0016] According to this configuration, the outer peripheral surface of the second electromagnetic shielding member is covered by the tape member, and the fixing ring is attached to the fixing portion so as to surround the outer periphery of the tape member. Therefore, when attaching the fixing ring, it is possible to preferably prevent the second electromagnetic shielding member from being caught by the fixing ring.

[0017] [6] In [5] above, the fixing ring may include a receiving portion and a lid portion that together surround the outer periphery of the electric wire over the entire circumferential direction. According to this configuration, since the fixing ring has a receiving portion and a lid portion, for example, the fixing ring can be retrofitted to the terminal cover. Thereby, the workability of assembling the wire harness can be improved as compared with, for example, the case where the fixing ring is a non-deformable cylindrical shape.

[0018] [7] In [5] or [6] above, the terminal cover houses the end portion of the electric wire in the first direction inside, the fixing portion is formed in a cylindrical shape that surrounds the outer periphery of the electric wire over the entire circumferential direction, the cross-sectional shape of the fixing portion is formed in an asymmetric shape, and the inner peripheral surface of the fixing ring may be formed in a shape along the outer peripheral surface of the fixing portion.

[0019] According to this configuration, the cylindrical fixing portion is formed in an asymmetric shape, and the inner peripheral surface of the fixing ring is formed along the outer peripheral surface of the fixing portion. Therefore, it is possible to preferably prevent the fixing ring from being attached to the fixing portion in an incorrect posture.

[0020] [8] In any one of [1] to [7] above, each of the first electromagnetic shielding member and the second electromagnetic shielding member may be a braided wire. With this configuration, a second electromagnetic shielding member, which is a braided wire, can be electrically connected to a first electromagnetic shielding member, which is a braided wire.

[0021] [9] In any of the above [1] to [8], the end of the first electromagnetic shielding member in the first direction has a separation portion that extends away from the electric wire without surrounding the outer circumference of the electric wire, and the wire harness may further have a grounding member that is connected to the tip of the separation portion and electrically connected to a grounding portion.

[0022] In this configuration, a grounding member is electrically connected to the tip of a separation portion provided at the first end of the first electromagnetic shielding member in a first direction. Furthermore, the grounding member is electrically connected to a grounding point provided on a vehicle or the like. This allows the tip of the separation portion to be electrically connected to the grounding point via the grounding member. As a result, the first electromagnetic shielding member can function effectively as an electromagnetic shielding member. Consequently, the second electromagnetic shielding member, electrically connected to the first electromagnetic shielding member, can also function effectively as an electromagnetic shielding member.

[0023] [Details of the embodiments of this disclosure] Specific examples of the wire harnesses of this disclosure will be described below with reference to the drawings. In each drawing, some parts of the configuration may be exaggerated or simplified for the sake of explanation. Also, the dimensional ratios of each part may differ in each drawing. In this specification, "parallel" and "orthogonal" include not only cases where they are strictly parallel or orthogonal, but also cases where they are roughly parallel or orthogonal within the range that produces the effects of this embodiment. As used in this description, "cylindrical" includes not only those in which a circumferential wall is formed continuously around the entire circumference, but also those formed by combining multiple parts to form a cylinder, or those having a cutout or the like in the circumferential direction, such as a C shape. The shape of "cylindrical" includes, but is not limited to, circular, elliptical, and polygons with pointed or rounded corners. In this specification, "opposing" means that faces or members are in a position facing each other. In this specification, "opposing" includes not only cases where they are completely facing each other, but also cases where they are partially facing each other. Furthermore, in this specification, "opposing" includes both cases where a member other than the two parts is interposed between the two parts, and cases where nothing is interposed between the two parts. Also, terms such as "first," "second," and "third" in this specification are used simply to distinguish objects and do not rank the objects. Each drawing shows a first axis X, a second axis Y perpendicular to the first axis X, and a third axis Z perpendicular to both the first axis X and the second axis Y. Each drawing also shows a first direction X1, which is one direction along the first axis X, and a first opposite direction X2, which is another direction along the first axis X and the opposite direction of the first direction X1. Each drawing also shows a second direction Y1, which is one direction along the second axis Y, and a second opposite direction Y2, which is another direction along the second axis Y and the opposite direction of the second direction Y1. Each drawing illustrates a third direction Z1, which is one direction along the third axis Z, and a third opposite direction Z2, which is the other direction along the third axis Z and is opposite to the third direction Z1. However, the present invention is not limited to these examples and is as shown in the claims, and all modifications within the meaning and scope of equivalence to the claims are intended.

[0024] (Overall configuration of wire harness 10) The wire harness 10 shown in Figure 1 is installed in vehicles such as hybrid cars and electric vehicles. The wire harness 10 electrically connects two or more electrical devices. Examples of electrical devices include batteries, inverters, motors, DC-DC converters, and junction boxes.

[0025] The wire harness 10 includes an electric wire 20, a terminal 30 connected to the end of the electric wire 20 in a first direction X1, a terminal cover 40 that houses the terminal 30, a first electromagnetic shielding member 60, and a second electromagnetic shielding member 70. The wire harness 10 also includes a fixing member 80, a connecting member 95, and a metal box 100.

[0026] (Configuration of the 20 electric wires) As shown in Figures 2 and 3, the electric wire 20 is a covered electric wire having a conductive core wire 21 and an insulating coating 22 that covers the outer circumference of the core wire 21. The insulating coating 22 covers the outer circumference of the core wire 21 around its entire circumference. The ends of the core wire 21 are exposed from the insulating coating 22.

[0027] (Configuration of terminal 30) As shown in Figure 2, the terminal 30 has a wire connection portion 31 that connects to the end of the wire 20 and a terminal connection portion 32 that connects to a mating terminal (not shown). The terminal 30 has a structure in which the wire connection portion 31 and the terminal connection portion 32 are arranged side by side along the first direction X1. The terminal 30 is a single component in which the wire connection portion 31 and the terminal connection portion 32 are continuously and integrally formed.

[0028] The wire connection part 31 is connected to the end of the core wire 21 exposed from the insulating coating 22. The wire connection part 31 is connected to the core wire 21 by crimping, resistance welding, or the like. In this embodiment, the wire connection part 31 is connected to the core wire 21 by crimping.

[0029] The terminal connection portion 32 is formed in a plate shape. The terminal connection portion 32 has a through hole 33 that penetrates the terminal connection portion 32 along the third axis Z. The through hole 33 is located at the center of the terminal connection portion 32 in a plan view in the third direction Z1. The terminal connection portion 32 is electrically connected to a mating terminal (not shown) by screw fastening using a screw (not shown) inserted into the through hole 33. The mating terminal is, for example, a terminal provided on an electrical device (not shown).

[0030] (Configuration of terminal cover 40) The terminal cover 40 houses the terminal 30 inside. The terminal cover 40 houses the end of the electric wire 20 in a first direction X1 inside. The terminal cover 40 extends, for example, along a first axis X. The terminal cover 40 is made of, for example, a synthetic resin. As the material for the terminal cover 40, synthetic resins such as polypropylene, polyamide, and polyacetal can be used.

[0031] As shown in Figure 4, the terminal cover 40 has a receiving portion 41, a lid portion 42, and one or more (two in this embodiment) hinge portions H1 connecting the receiving portion 41 and the lid portion 42. The terminal cover 40 is, for example, a single component in which the receiving portion 41, the hinge portion H1, and the lid portion 42 are formed in a continuous, integral manner.

[0032] The cover portion 42 is rotatable relative to the receiving portion 41 around the hinge portion H1. The cover portion 42 is formed to be rotatable between the closed position shown in Figure 3 and the open position shown in Figure 4, with the hinge portion H1 as the axis. As shown in Figure 3, when the cover portion 42 is in the closed position, the terminal cover 40 covers the end of the electric wire 20 and the terminal 30. In the closed position, the cover portion 42, together with the receiving portion 41, covers the outer circumference of the end of the electric wire 20 and the outer circumference of the terminal 30 over the entire circumference.

[0033] As shown in Figure 4, the receiving portion 41 is formed in a half-cylindrical shape overall. The receiving portion 41 has a first bottom wall 43 facing the lid portion 42, and two first side walls 44A and 44B that protrude toward the lid portion 42 from both side edges of the first bottom wall 43. The first bottom wall 43 is formed in a plate shape.

[0034] The first bottom wall 43 is provided with a through hole 43X that penetrates the first bottom wall 43 along the third axis Z. The through hole 43X is located at the end of the first bottom wall 43 in the first direction X1. As shown in Figure 3, the through hole 43X is located in a position that overlaps with the terminal connection portion 32 of the terminal 30 in a plan view in the third direction Z1.

[0035] As shown in Figure 4, each first side wall 44A, 44B is formed integrally with the first bottom wall 43 in a continuous manner. The first side wall 44A protrudes from the end of the first bottom wall 43 in the second direction Y1 toward the third direction Z1. The first side wall 44B protrudes from the end of the first bottom wall 43 in the second opposite direction Y2 toward the third direction Z1. The two first side walls 44A, 44B face each other along the second axis Y. Each first side wall 44A, 44B is formed in a plate shape. A hinge portion H1 is connected to the end of the first side wall 44B in the third direction Z1.

[0036] The receiving portion 41 has one or more (four in this embodiment) first engaging portions 45. Three of the first engaging portions 45 are provided on the first side wall 44A. The three first engaging portions 45 are provided at intervals along the first axis X. One of the first engaging portions 45 is provided at the end of the first side wall 44B in the first direction X1. Each first engaging portion 45 is, for example, a projection that protrudes toward the third direction Z1 from the end face of the first side walls 44A, 44B toward the third direction Z1, and also protrudes outward from the outer surface of the first side walls 44A, 44B.

[0037] The lid portion 42 is formed in a half-cylindrical shape overall. The lid portion 42 has a second bottom wall 46 facing the receiving portion 41, and two second side walls 47A and 47B that protrude toward the receiving portion 41 from both side edges of the second bottom wall 46.

[0038] Each second side wall 47A, 47B is formed integrally with the second bottom wall 46. In the open position, the second side wall 47A protrudes from the end of the second bottom wall 46 in the second opposite direction Y2 toward the third direction Z1. In the open position, the second side wall 47B protrudes from the end of the second bottom wall 46 in the second direction Y1 toward the third direction Z1. The two second side walls 47A, 47B face each other along the second axis Y. Each second side wall 47A, 47B is formed in a plate shape.

[0039] As shown in Figure 1, the lid portion 42 has a main body portion 51, an opening / closing portion 52, and a hinge portion H2 connecting the main body portion 51 and the opening / closing portion 52. For example, the lid portion 42 is formed by continuously integrating the main body portion 51, the hinge portion H2, and the opening / closing portion 52.

[0040] As shown in Figure 4, the main body 51 is connected to the receiving portion 41 via a thin-walled hinge portion H1. In this embodiment, the main body 51 is connected to the receiving portion 41 via two hinge portions H1 that are spaced apart from each other along the first axis X. More specifically, one circumferential end of the main body 51 is connected to one circumferential end of the receiving portion 41 via a thin-walled hinge portion H1. The main body 51 is rotatable around the hinge portion H1 relative to the receiving portion 41.

[0041] As shown in Figure 3, the main body 51 has a retaining portion 53. The retaining portion 53 protrudes from the inner surface of the second bottom wall 46 toward the connection portion between the electric wire 20 and the terminal 30. In the closed position, the retaining portion 53 extends from the inner surface of the second bottom wall 46 along a third opposite direction Z2. The retaining portion 53 is formed to, for example, press the connection portion between the electric wire 20 and the terminal 30 from the third direction Z1. The retaining portion 53 restricts the movement of the electric wire 20 and the terminal 30 in the third direction Z1.

[0042] The opening / closing section 52 is connected to the main body 51 via a thin hinge section H2. The opening / closing section 52 is rotatable relative to the main body 51 around the hinge section H2. The opening / closing section 52 is formed to be rotatable between the closed state shown in Figure 3 and the open state shown in Figure 1, with the hinge section H2 as its axis. As shown in Figure 3, in the closed state, the opening / closing section 52 covers the outer circumference of the terminal connection section 32 of the terminal 30. As shown in Figure 1, in the open state, the opening / closing section 52 exposes the terminal connection section 32 to the outside. Note that, as shown in Figure 4, the hinge section H1 is not connected to the opening / closing section 52. That is, the opening / closing section 52 is not connected to the receiving section 41 via the hinge section H1.

[0043] The lid portion 42 has one or more (four in this embodiment) second engaging portions 48. Two of the second engaging portions 48 are provided on the second side wall 47A of the main body portion 51. The two second engaging portions 48 are spaced apart along the first axis X. One second engaging portion 48 is provided on the second side wall 47A of the opening / closing portion 52. One second engaging portion 48 is provided on the second side wall 47B of the opening / closing portion 52. Each second engaging portion 48 is formed to be engageable with each first engaging portion 45 provided on the receiving portion 41. Each second engaging portion 48 is, for example, an engaging frame portion formed to protrude outward from the outer surface of the second side walls 47A, 47B. Each second engaging portion 48 is formed to be elastically deformable. Each second engaging portion 48 is, for example, formed as a rectangular frame and has an engaging hole in the center of the frame into which the first engaging portion 45 engages. Each first engaging portion 45 and each second engaging portion 48 engage with each other, for example, by a snap-fit ​​method utilizing the elastic deformation of the second engaging portion 48. The engagement of the second engaging portion 48 and the first engaging portion 45 provided on the main body portion 51 restricts the movement of the lid portion 42 toward the open position. This allows the closed position of the lid portion 42 to be suitably maintained. Furthermore, the engagement of the second engaging portion 48 and the first engaging portion 45 provided on the opening / closing portion 52 restricts the movement of the opening / closing portion 52 toward the open state. This allows the closed state of the opening / closing portion 52 to be suitably maintained.

[0044] As shown in Figure 2, the terminal cover 40 has a fixing portion 55 to which the second electromagnetic shielding member 70 is fixed by a fixing member 80. The fixing portion 55 is located at an intermediate position in the axial direction of the terminal cover 40 (here, in the direction along the first axis X). The outer circumferential surface of the fixing portion 55 is formed in a groove shape so as to be recessed radially inward from the outer circumferential surface of the terminal cover 40 other than the fixing portion 55. The fixing portion 55 does not have a hinge portion H1. Two hinge portions H1 are provided so as to sandwich the fixing portion 55 in the first axis X. The fixing portion 55 does not have a first engaging portion 45 or a second engaging portion 48.

[0045] As shown in Figure 5, the fixing portion 55 is formed in a cylindrical shape that surrounds the outer circumference of the electric wire 20 around its entire circumference when the lid portion 42 is in the closed position. The cross-sectional shape of the fixing portion 55 is, for example, asymmetrical. More specifically, the cross-sectional shape of the fixing portion 55 is rectangular overall. However, in the cross-sectional shape of the fixing portion 55, only one of the four corners (the upper right corner in the figure) is formed as a curved portion 56 that is more curved than the other three corners. The curved portion 56 is provided, for example, at the corner between the second bottom wall 46 and the second side wall 47A of the lid portion 42.

[0046] (Configuration of the first electromagnetic shielding member 60) As shown in Figure 2, the first electromagnetic shielding member 60 is formed in a cylindrical shape, for example. The first electromagnetic shielding member 60 surrounds the outer circumference of the electric wire 20 around its entire circumference. The first electromagnetic shielding member 60 is, for example, flexible. As the first electromagnetic shielding member 60, for example, a braided wire or metal foil in which multiple metal strands are woven into a cylindrical shape can be used. In this embodiment, the first electromagnetic shielding member 60 is a braided wire. As the material for the first electromagnetic shielding member 60, for example, a metal material such as copper-based or aluminum-based materials can be used.

[0047] The end of the first electromagnetic shielding member 60 in the first direction X1 has a separation portion 61 that extends away from the electric wire 20 without surrounding the outer circumference of the electric wire 20. The separation portion 61 extends, for example, in a direction intersecting the longitudinal direction of the electric wire 20 (here, the second direction Y1). The tip of the separation portion 61 is electrically connected to, for example, a metal grounding terminal 62. The grounding terminal 62 is electrically connected to, for example, a grounding point G1 provided on a vehicle body panel or the like. The tip of the separation portion 61 is grounded to the grounding point G1 through the grounding terminal 62. Here, the tip of the separation portion 61 is the end of the axial end of the separation portion 61 that is furthest from the electric wire 20. As for the method of joining the separation portion 61 and the grounding terminal 62, crimping, welding such as ultrasonic welding or laser welding, or other known joining methods can be used.

[0048] The first electromagnetic shielding member 60 is formed to expose the terminal cover 40. The first electromagnetic shielding member 60 is formed to expose the portion of the electric wire 20 located between the separation portion 61 and the terminal cover 40.

[0049] (Configuration of the second electromagnetic shielding member 70) The second electromagnetic shielding member 70 is formed, for example, in a cylindrical shape. The second electromagnetic shielding member 70 surrounds the outer circumference of the electric wire 20 over its entire circumference and also surrounds the outer circumference of the terminal cover 40 over its entire circumference. The second electromagnetic shielding member 70 is, for example, flexible. For the second electromagnetic shielding member 70, for example, braided wire or metal foil can be used. In this embodiment, the second electromagnetic shielding member 70 is braided wire. For the material of the second electromagnetic shielding member 70, for example, a metal material such as copper-based or aluminum-based material can be used.

[0050] The second electromagnetic shielding member 70 is formed to surround the outer circumference of the electric wire 20 that is exposed from the first electromagnetic shielding member 60. The second electromagnetic shielding member 70 is formed to surround the outer circumference of a part of the terminal cover 40. For example, the second electromagnetic shielding member 70 is formed to surround the outer circumference of the terminal cover 40 from the end in the first opposite direction X2 to the fixing portion 55.

[0051] The second electromagnetic shielding member 70 has a first end 71 and a second end 72. The first end 71 is positioned in the first opposite direction X2 from the terminal cover 40, and also in the first direction X1 from the end of the first electromagnetic shielding member 60 in that direction. That is, the first end 71 is positioned so as not to overlap with the first electromagnetic shielding member 60 on the first axis X. The first end 71 is fixed to the outer circumference of the electric wire 20 by, for example, a fixing member 75. Here, the fixing member 75 can be, for example, a tape member, a cable tie, or a crimping band. In this embodiment, the fixing member 75 is a tape member.

[0052] The fixing member 75 is formed to fix the axial first end 71 of the second electromagnetic shielding member 70 to the outer circumferential surface of the insulating coating 22 of the electric wire 20. The fixing member 75 is wound, for example, over the outer circumferential surface of the first end 71 of the second electromagnetic shielding member 70 and over the outer circumferential surface of the electric wire 20 exposed from the first electromagnetic shielding member 60 and the second electromagnetic shielding member 70. The fixing member 75 is wound continuously over the range from the outer circumferential surface of the second electromagnetic shielding member 70 to the outer circumferential surface of the electric wire 20. The fixing member 75 covers the outer circumference of the second electromagnetic shielding member 70 over its entire circumference and also covers the outer circumference of the electric wire 20 over its entire circumference. The fixing member 75 has, for example, an overlapping winding structure.

[0053] Here, the overlap winding structure is a structure in which tape members are wound spirally so that predetermined portions of the tape members overlap in the width direction. An example of an overlap winding structure is a half-wrap winding, in which tape members are wound spirally so that approximately half of the tape members overlap in the width direction.

[0054] The axial intermediate portion of the second electromagnetic shielding member 70 is fixed, for example, to the outer circumferential surface of the fixing portion 55 of the terminal cover 40 by a fixing member 80. (Configuration of the fixing member 80) Here, the fixing member 80 includes, for example, a tape member 81 and a fixing ring 82. The tape member 81 tightens the second electromagnetic shielding member 70 toward the terminal cover 40, that is, radially inward, so that the inner circumferential surface of the second electromagnetic shielding member 70 comes into contact with the outer circumferential surface of the fixing part 55. The tape member 81 is formed to cover the outer circumferential surface of the second electromagnetic shielding member 70. The tape member 81 is formed to cover the mesh of the second electromagnetic shielding member 70, which is, for example, a braided wire. The tape member 81 is provided, for example, only on the outer circumference of the fixing part 55. The tape member 81 is formed to extend along the first axis X within the fixing part 55.

[0055] The tape member 81 has, for example, an overlap winding structure. Although detailed illustrations are omitted, the tape member 81 is wrapped multiple times around the second electromagnetic shielding member 70 in the circumferential direction, for example, by a half-wrap winding structure. As shown in Figure 5, the tightening by the tape member 81 causes the inner circumferential surface of the second electromagnetic shielding member 70 to be in contact with the outer circumferential surface of the fixing portion 55 in the circumferential direction.

[0056] The fixing ring 82 is attached to the outer circumference of the fixing portion 55. The fixing ring 82 is formed in a ring shape (cylindrical shape) that surrounds the outer circumference of the fixing portion 55. The fixing ring 82 is attached to the outer circumference of the fixing portion 55 so as to surround the outer circumference of the tape member 81. The fixing ring 82 is provided so as to overlap with the tape member 81 in the axial direction of the terminal cover 40. The fixing ring 82 is made of, for example, synthetic resin or metal. In this embodiment, the fixing ring 82 is made of synthetic resin. As the material for the fixing ring 82, for example, synthetic resins such as polypropylene, polyamide, and polyacetal can be used.

[0057] As shown in Figure 6, the fixing ring 82 has a receiving portion 83, a lid portion 84, and one or more (one in this embodiment) hinge portions H3 connecting the receiving portion 83 and the lid portion 84. The fixing ring 82 is, for example, a single component in which the receiving portion 83, the hinge portion H3, and the lid portion 84 are continuously and integrally formed.

[0058] The lid portion 84 is rotatable relative to the receiving portion 83 around the hinge portion H3. The lid portion 84 is formed to be rotatable between the closed position shown in Figure 5 and the open position shown in Figure 6, with the hinge portion H3 as the axis. As shown in Figure 5, the fixing ring 82 is configured as a ring that surrounds the outer circumference of the fixing portion 55 around its entire circumference when the lid portion 84 is in the closed position. The fixing ring 82 surrounds the outer circumference of the second electromagnetic shielding member 70, which is covered by the tape member 81, around its entire circumference.

[0059] The receiving portion 83 is formed in a half-cylindrical shape overall. The cross-sectional shape of the receiving portion 83 is formed in a U-shape overall. The receiving portion 83 has a third bottom wall 85 facing the lid portion 84, and two third side walls 86A and 86B that protrude toward the lid portion 84 from both side edges of the third bottom wall 85.

[0060] The third bottom wall 85 is formed in a plate shape. The third bottom wall 85 is formed to face the first bottom wall 43. The outer surface of the third bottom wall 85, that is, the end face of the third bottom wall 85 in the third opposite direction Z2, is formed, for example, as a flat surface.

[0061] As shown in Figure 6, each third side wall 86A, 86B is formed integrally with the third bottom wall 85 in a continuous manner. The third side wall 86A protrudes from the end of the third bottom wall 85 in the second direction Y1 toward the third direction Z1. The third side wall 86B protrudes from the end of the third bottom wall 85 in the second opposite direction Y2 toward the third direction Z1. The two third side walls 86A, 86B face each other along the second axis Y. Each third side wall 86A, 86B is formed in a plate shape. A hinge portion H3 is connected to the end of the third side wall 86B in the third direction Z1.

[0062] The receiving portion 83 has one or more (in this embodiment, one) third engaging portions 87. The third engaging portion 87 is provided on the third side wall 86A. The third engaging portion 87 is, for example, a projection that protrudes toward the third direction Z1 from the end face of the third side wall 86A toward the third direction Z1, and also protrudes outward from the outer surface of the third side wall 86A.

[0063] The lid portion 84 is formed in a half-cylindrical shape overall. The cross-sectional shape of the lid portion 84 is formed in a U-shape overall. The lid portion 84 has a fourth bottom wall 88 facing the receiving portion 83, and two fourth side walls 89A and 89B that protrude toward the receiving portion 83 from both side edges of the fourth bottom wall 88.

[0064] The fourth bottom wall 88 is formed in a plate shape. As shown in Figure 3, the inner surface of the fourth bottom wall 88, that is, the end face of the fourth bottom wall 88 in the third opposite direction Z2, is formed to face the second bottom wall 46. The outer surface of the fourth bottom wall 88, that is, the end face of the fourth bottom wall 88 in the third direction Z1, is the opposing surface 88A that faces the inner surface of the box body 100. The opposing surface 88A is formed, for example, as a flat surface.

[0065] As shown in Figure 5, each of the fourth side walls 89A and 89B is formed integrally with the fourth bottom wall 88. In the closed position, the fourth side wall 89A protrudes from the end of the fourth bottom wall 88 in the second direction Y1 toward the third opposite direction Z2. In the closed position, the fourth side wall 89B protrudes from the end of the fourth bottom wall 88 in the second opposite direction Y2 toward the third opposite direction Z2. The two fourth side walls 89A and 89B face each other along the second axis Y. Each of the fourth side walls 89A and 89B is formed in a plate shape.

[0066] As shown in Figure 6, the lid portion 84 is connected to the receiving portion 83 via a thin hinge portion H3. More specifically, one circumferential end of the lid portion 84 (specifically, the end of the fourth side wall 89B) is connected to one circumferential end of the receiving portion 83 (specifically, the end of the third side wall 86B) via the thin hinge portion H3. The lid portion 84 is rotatable about the hinge portion H3 relative to the receiving portion 83.

[0067] The lid portion 84 has one or more (one in this embodiment) fourth engaging portions 90. The fourth engaging portion 90 is provided on the fourth side wall 89A. The fourth engaging portion 90 is formed to be engageable with a third engaging portion 87 provided on the receiving portion 83. The fourth engaging portion 90 is, for example, an engaging frame portion formed to protrude outward from the outer surface of the fourth side wall 89A. The fourth engaging portion 90 is formed to be elastically deformable. The fourth engaging portion 90 is, for example, formed in the shape of a rectangular frame and has an engaging hole in the center of the frame into which the third engaging portion 87 engages. The third engaging portion 87 and the fourth engaging portion 90 are engaged with each other, for example, by a snap-fit ​​method utilizing the elastic deformation of the fourth engaging portion 90. By engaging the third engaging portion 87 and the fourth engaging portion 90 with each other, the movement of the lid portion 84 toward the open position can be restricted. This allows the closed position of the lid portion 84 to be suitably maintained.

[0068] As shown in Figure 5, the inner circumferential surface of the fixing ring 82 is formed in a shape that conforms to the outer circumferential surface of the fixing portion 55. The inner circumferential surface of the fixing ring 82 has a curved surface 91 that conforms to the curved portion 56 of the fixing portion 55. The curved surface 91 is provided on the lid portion 84. The curved surface 91 is provided at the corner between the fourth bottom wall 88 and the fourth side wall 89A. Such a fixing ring 82 can only be attached to the outer circumference of the fixing portion 55 in an orientation where the curved surface 91 faces the curved portion 56.

[0069] (Configuration of the second electromagnetic shielding member 70) As shown in Figure 2, the second electromagnetic shielding member 70 has a folded portion 73 that is folded back toward the first electromagnetic shielding member 60. The folded portion 73 is formed to be folded back toward the outside of the fixing member 80 from a position toward the first direction X1 toward the fixing member 80, for example. The folded portion 73 is folded back from the fixing member 80, for example. The folded portion 73 is formed to surround the outer circumference of the fixing ring 82 over its entire circumference. The folded portion 73 is formed to surround the outer circumference of a part of the terminal cover 40 over its entire circumference. The folded portion 73 is formed to surround the outer circumference of the electric wire 20 exposed from the first electromagnetic shielding member 60 and the terminal cover 40 over its entire circumference. The folded portion 73 extends to the end of the first electromagnetic shielding member 60 in the first direction X1. The folded portion 73 extends to a position in the first opposite direction X2 from the separation portion 61, for example, by utilizing the mesh of the braided wire and the gaps between the metal strands constituting the braided wire to avoid the separation portion 61. Here, the tip of the folded portion 73 is the second end portion 72 of the second electromagnetic shielding member 70. The second end portion 72 is formed, for example, to surround the outer circumference of the first electromagnetic shielding member 60 over its entire circumference. The second end portion 72 is electrically connected to the first electromagnetic shielding member 60 by a connecting member 95. As a result, the second electromagnetic shielding member 70 is grounded to the grounding portion G1 through the first electromagnetic shielding member 60, the separation portion 61, and the grounding terminal 62.

[0070] (Configuration of connecting member 95) As the connecting member 95, for example, a tape member, a cable tie, or a crimping band can be used. In this embodiment, the connecting member 95 is a tape member.

[0071] The connecting member 95 is formed to bring the inner circumferential surface of the second end 72 of the second electromagnetic shielding member 70 into contact with the outer circumferential surface of the first electromagnetic shielding member 60. The connecting member 95 tightens the second end 72 of the second electromagnetic shielding member 70 radially inward. The connecting member 95 is wound, for example, over the outer circumferential surface of the second end 72 of the second electromagnetic shielding member 70 and the outer circumferential surface of the first electromagnetic shielding member 60 exposed from the second electromagnetic shielding member 70. The connecting member 95 is wound continuously over the range from the outer circumferential surface of the second electromagnetic shielding member 70 to the outer circumferential surface of the first electromagnetic shielding member 60. The connecting member 95 covers, for example, the entire circumference of the outer circumferential surface of the second electromagnetic shielding member 70 and the entire circumference of the outer circumferential surface of the first electromagnetic shielding member 60. The connecting member 95 has, for example, an overlap winding structure.

[0072] (Composition of box 100) As shown in Figure 3, the box 100 is formed in a box shape capable of housing, for example, the terminal cover 40 inside. The box 100 has, for example, an opening 101 that opens toward the first opposite direction X2. The electric wire 20 and the second electromagnetic shielding member 70 are led out of the box 100 through the opening 101.

[0073] As shown in Figure 1, the box body 100 has, for example, one or more (two in this embodiment) box body fixing parts 102 that protrude outward from the outer circumferential surface of the box body 100. Each box body fixing part 102 is formed, for example, in the shape of a plate. Each box body fixing part 102 has a through hole 103 that penetrates the box body fixing part 102 along the third axis Z. The box body 100 is fixed to a mounting target such as a vehicle body panel (not shown) by screw fastening using screws (not shown) inserted into the through holes 103 of the box body fixing part 102. By being fixed to the mounting target such as a vehicle body panel, the box body 100 is connected to the grounding part G2. Note that the grounding part G2 may be a different grounding part from the grounding part G1, or it may be the same grounding part as the grounding part G1.

[0074] As shown in Figure 3, a connecting member 110 is provided on the inner surface of the box body 100 to electrically connect the box body 100 and the second electromagnetic shielding member 70. The connecting member 110 is fixed, for example, to the portion of the inner surface of the box body 100 that faces the fixing ring 82. The connecting member 110 is provided so as to protrude from the inner surface of the box body 100 toward the fixing ring 82. The connecting member 110 is fixed to the inner surface of the box body 100 by, for example, a conductive joining member (not shown).

[0075] The connecting member 110 includes, for example, an elastic member 111 and a conductor 112 covering the surface of the elastic member 111. A soft gasket can be used as the connecting member 110. The elastic member 111 is formed, for example, in a rectangular parallelepiped shape. Urethane foam or the like can be used as the material for the elastic member 111. The conductor 112 is formed to cover the entire surface of the elastic member 111.

[0076] The connecting member 110 is positioned between the fixing ring 82 and the inner surface of the box body 100. The end face of the connecting member 110 in the third opposite direction Z2 faces the opposing surface 88A of the fixing ring 82. The end face of the connecting member 110 in the third opposite direction Z2 contacts the folded portion 73 of the second electromagnetic shielding member 70 provided on the opposing surface 88A. More specifically, when the box body 100 is screwed to the mounting object with screws (not shown), the connecting member 110 is compressed in the third direction Z1 between the opposing surface 88A of the fixing ring 82 and the inner surface of the box body 100 by pressure from the inner surface of the box body 100. As a result, the connecting member 110 is pressed against the outer circumferential surface of the second electromagnetic shielding member 70 provided on the opposing surface 88A. Consequently, the second electromagnetic shielding member 70 is grounded to the grounding point G2 (see Figure 1) through the connecting member 110 and the box body 100.

[0077] (Method for manufacturing wire harness 10) Next, the manufacturing method of the wire harness 10 will be described. First, in the process shown in Figure 7, a structure is prepared that includes an electric wire 20, a terminal 30 connected to the end of the electric wire 20, a terminal cover 40 that houses the terminal 30 inside, and a first electromagnetic shielding member 60 having a separation portion 61.

[0078] Next, the terminal cover 40 and a portion of the electric wire 20 are housed inside the cylindrical second electromagnetic shielding member 70. At this time, the second electromagnetic shielding member 70 surrounds the outer circumference of the electric wire 20 located between the terminal cover 40 and the first electromagnetic shielding member 60. The second electromagnetic shielding member 70 also surrounds the entire terminal cover 40. More specifically, the second electromagnetic shielding member 70 surrounds the outer circumference of the terminal cover 40 over its entire circumference. The second electromagnetic shielding member 70 surrounds the outer circumference of the terminal cover 40 over its entire axial length.

[0079] Next, the first end 71 of the second electromagnetic shielding member 70 is fixed to the outer surface of the electric wire 20 by the fixing member 75. At this time, the first end 71 is fixed to the outer surface of the electric wire 20 by the fixing member 75 at a position that does not overlap with the first electromagnetic shielding member 60. This makes it possible to stably fix the second electromagnetic shielding member 70 to the outer surface of the electric wire 20.

[0080] Next, in the step shown in Figure 8, the axial middle portion of the second electromagnetic shielding member 70 is fixed to the outer circumferential surface of the fixing portion 55 of the terminal cover 40 by the tape member 81. This tape member 81 tightens the axial middle portion of the second electromagnetic shielding member 70 radially inward.

[0081] Next, in the step shown in Figure 9, a fixing ring 82 is attached to the outer circumference of the fixing part 55. The fixing ring 82 is maintained in a cylindrical state that surrounds the outer circumference of the fixing part 55 and the second electromagnetic shielding member 70 by engaging the third engaging part 87 and the fourth engaging part 90 with each other in a snap-fit ​​manner. At this time, since the second electromagnetic shielding member 70 is tightened radially inward by the tape member 81, it is possible to suitably prevent the second electromagnetic shielding member 70 from getting caught in the engagement portion between the third engaging part 87 and the fourth engaging part 90. As a result, the third engaging part 87 and the fourth engaging part 90 can be suitably engaged, and the fixing ring 82 can be suitably maintained in a cylindrical state.

[0082] Next, in the process shown in Figure 10, the second electromagnetic shielding member 70 is folded back toward the first electromagnetic shielding member 60, starting from the fixing ring 82. At this time, the second electromagnetic shielding member 70 is folded back until its second end 72 overlaps with the first electromagnetic shielding member 60.

[0083] Next, in the step shown in Figure 11, the second end 72 of the second electromagnetic shielding member 70 is connected to the first electromagnetic shielding member 60 by a connecting member 95. The connecting member 95 is formed to bring the second electromagnetic shielding member 70 into contact with the first electromagnetic shielding member 60 by tightening the second end 72 radially inward. This allows the second electromagnetic shielding member 70 to be electrically connected to the first electromagnetic shielding member 60. Consequently, the second electromagnetic shielding member 70 can be grounded to the grounding point G1 through the first electromagnetic shielding member 60, the separation part 61, and the grounding terminal 62.

[0084] (Effects of this embodiment) Next, the effects and advantages of this embodiment will be explained. (1) The wire harness 10 includes an electric wire 20, a terminal 30 connected to the end of the electric wire 20 in a first direction X1, a terminal cover 40 that houses the terminal 30, and a first electromagnetic shielding member 60 that surrounds the outer circumference of the electric wire 20. The wire harness 10 also includes a second electromagnetic shielding member 70 that surrounds the outer circumference of the electric wire 20 exposed from the first electromagnetic shielding member 60 and surrounds the outer circumference of the terminal cover 40, and a fixing member 80 that fixes the second electromagnetic shielding member 70 to the outer circumference of the terminal cover 40. The wire harness 10 has a connecting member 95 that electrically connects the first electromagnetic shielding member 60 and the second electromagnetic shielding member 70. The second end 72 of the second electromagnetic shielding member 70 surrounds the outer circumference of the first electromagnetic shielding member 60 and is electrically connected to the first electromagnetic shielding member 60 by the connecting member 95.

[0085] In this configuration, the outer circumference of the wire 20 exposed from the first electromagnetic shielding member 60 is surrounded by the second electromagnetic shielding member 70, which is electrically connected to the first electromagnetic shielding member 60, and the outer circumference of the terminal cover 40 is also surrounded. As a result, the wire 20 exposed from the first electromagnetic shielding member 60 and the terminal cover 40 can be electromagnetically shielded by the second electromagnetic shielding member 70. As a result, the degradation of electromagnetic shielding performance in the wire 20 exposed from the first electromagnetic shielding member 60 and the terminal cover 40 can be effectively suppressed.

[0086] (2) However, as the axial length of the terminal cover 40 increases, the length of the electric wire 20 exposed from the first electromagnetic shielding member 60 also increases. Therefore, as the axial length of the terminal cover 40 increases, the electromagnetic shielding performance at the end of the electric wire 20 in the first direction X1 tends to decrease. In contrast, in the wire harness 10 of this embodiment, the electric wire 20 exposed from the first electromagnetic shielding member 60 and the terminal cover 40 are surrounded by the second electromagnetic shielding member 70. Therefore, even if the axial length of the terminal cover 40 increases, the decrease in electromagnetic shielding performance at the end of the electric wire 20 in the first direction X1 can be effectively suppressed.

[0087] (3) The wire harness 10 has a fixing member 75 that fixes the first end 71 of the second electromagnetic shielding member 70 to the outer circumference of the electric wire 20. The first end 71 is located in a position opposite to the terminal cover 40 in a first direction X2. The second electromagnetic shielding member 70 has a folded portion 73 that is folded back toward the first electromagnetic shielding member 60 from a position toward the first direction X1 toward the fixing member 80. The folded portion 73 surrounds the outer circumference of the fixing member 80. The tip of the folded portion 73 is the second end 72 of the second electromagnetic shielding member 70.

[0088] With this configuration, the area of ​​the second electromagnetic shielding member 70 from the first end 71 to the folded portion 73, and the folded portion 73 of the second electromagnetic shielding member 70, double-enclose a portion of the outer circumference of the terminal cover 40 and a portion of the outer circumference of the electric wire 20. As a result, the second electromagnetic shielding member 70 with the folded portion 73 can stably electromagnetically shield the terminal cover 40 and the electric wire 20.

[0089] (4) The first end 71 of the second electromagnetic shielding member 70 is fixed to the outer circumference of the electric wire 20 by a fixing member 75 at a position that does not overlap with the first electromagnetic shielding member 60. As a result, the first end 71 can be directly fixed to the outer circumference of the electric wire 20, and the first end 71 can be stably fixed to the outer circumference of the electric wire 20.

[0090] (5) The outer surface of the fixing portion 55 of the terminal cover 40 is formed in a groove shape. Therefore, even when the fixing member 80 is attached to the fixing portion 55, it is possible to effectively suppress an increase in the overall size of the wire harness 10.

[0091] (6) The outer surface of the second electromagnetic shielding member 70 is covered by the tape member 81, and the fixing ring 82 is attached to the fixing part 55 so as to surround the outer surface of the tape member 81. This effectively prevents the second electromagnetic shielding member 70 from getting caught in the fixing ring 82 when the fixing ring 82 is attached.

[0092] (7) Since the fixing ring 82 has a receiving portion 83 and a cover portion 84, for example, the fixing ring 82 can be retrofitted to the terminal cover 40. This improves the assembly workability of the wire harness 10 compared to, for example, when the fixing ring 82 is a non-deformable cylindrical shape.

[0093] (8) The cylindrical fixing portion 55 is formed in an asymmetrical shape, and the inner surface of the fixing ring 82 is formed along the outer surface of the fixing portion 55. Therefore, it is possible to effectively prevent the fixing ring 82 from being attached to the fixing portion 55 in an incorrect position.

[0094] (9) An earth terminal 62 is electrically connected to the tip of a separation portion 61 provided at the end of the first electromagnetic shielding member 60 in the first direction X1. The earth terminal 62 is also electrically connected to a grounding point G1 provided on a vehicle or the like. This allows the tip of the separation portion 61 to be electrically connected to the grounding point G1 through the earth terminal 62. As a result, the first electromagnetic shielding member 60 can function suitably as an electromagnetic shielding member. Consequently, the second electromagnetic shielding member 70, which is electrically connected to the first electromagnetic shielding member 60, can function suitably as an electromagnetic shielding member.

[0095] (10) The second electromagnetic shielding member 70 is electrically connected to the metal housing 100 through the connecting member 110. As a result, the second electromagnetic shielding member 70 is grounded through the connecting member 110 and the housing 100, and also grounded through the first electromagnetic shielding member 60. Therefore, the second electromagnetic shielding member 70 can be grounded through two paths: the path through the connecting member 110 and the housing 100, and the path through the first electromagnetic shielding member 60. For this reason, even if a problem occurs in one path, the second electromagnetic shielding member 70 can be suitably grounded through the remaining path.

[0096] (Example of change) The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0097] The structure of the second electromagnetic shielding member 70 in the above embodiment can be modified as appropriate. For example, the second electromagnetic shielding member 70 may be modified to have a structure that does not have a folded portion 73.

[0098] The fixing position of the first end 71 of the second electromagnetic shielding member 70 in the above embodiment can be changed as appropriate. For example, the first end 71 may be provided in a position that overlaps with the first electromagnetic shielding member 60.

[0099] The structure of the terminal cover 40 in the above embodiment can be modified as appropriate. In the above embodiment, the terminal cover 40 is embodied as a single component in which the receiving portion 41 and the lid portion 42 are integrally formed via the hinge portion H1, but it is not limited to this. For example, the receiving portion 41 and the lid portion 42 of the terminal cover 40 may be made up of separate components.

[0100] In the above embodiment, the lid portion 42 is embodied as a single component in which the main body portion 51 and the opening / closing portion 52 are integrally formed via the hinge portion H2, but it is not limited to this. For example, the main body portion 51 and the opening / closing portion 52 of the lid portion 42 may be made of separate components. Alternatively, the lid portion 42 may be modified to have a structure without the opening / closing portion 52.

[0101] The retaining portion 53 in the lid portion 42 of the above embodiment may be omitted. The structures of the first engaging portion 45 and the second engaging portion 48 in the above embodiment can be modified as appropriate. Furthermore, the formation positions and number of the first engaging portion 45 and the second engaging portion 48 can be modified as appropriate.

[0102] The structure of the fixing portion 55 in the above embodiment can be modified as appropriate. For example, the outer circumferential surface of the fixing portion 55 does not have to be formed in a groove shape. For example, the cross-sectional shape of the fixing portion 55 may be formed in a symmetrical shape.

[0105] In the above embodiment, the opposing surface 88A of the fixing ring 82 is formed as a flat surface, but this is not limited to this. For example, the opposing surface 88A may be formed as a curved surface, or the opposing surface 88A may be formed as an uneven surface.

[0106] The connecting member 110 in the above embodiment may be omitted. In this case, the second electromagnetic shielding member 70 is not electrically connected to the box body 100, for example. In this case, the second electromagnetic shielding member 70 is grounded only by a path through the first electromagnetic shielding member 60, the separation section 61, and the ground terminal 62, for example.

[0107] In the above embodiment, the ground terminal 62 is connected to the tip of the separation portion 61, but the embodiment is not limited to this. For example, a grounding member other than the ground terminal 62 may be connected to the tip of the separation portion 61.
