WIRE HARNESS

To provide a wire harness that restricts rotation of a wire in a holder, a wire harness includes a tubular member, a wire member extending through the tubular member, and a tubular holder holding the wire member in the tubular member. The holder includes a first segment and a second segment, which are separated by a separation plane extending in a longitudinal direction of the holder. The first segment includes a holding portion that holds the wire member in the holder. Also, the second segment includes a holding portion that holds the wire member in the holder.

BACKGROUND

The following description relates to a wire harness.

2. Description of Related Art

A conventional wire harness used in a vehicle such as a hybrid vehicle or an electric vehicle includes a wire and a metal shield pipe through which the wire extends. An end of the wire is drawn out from an end of the shield pipe and then connected to an electric device through a desired route. Japanese Laid-Open Patent Publication No. 2015-35915 discloses an example of this type of wire harness that includes a resin holder attached to an axial end of the shield pipe. The resin holder is attached to the inside of the shield pipe. This hampers contact of the wire, which extends through the inside of the shield pipe, with an edge of the end of the shield pipe, thereby limiting damage to an insulation covering of the wire.

SUMMARY

In the conventional wire harness, the inner circumferential surface of the holder has a true-circular cross section. Thus, the holder is likely to be separated from the wire by a large gap. This allows the wire to easily rotate in the holder. A jig for restraining the wire may be used to restrict rotation of the wire. However, the jig needs to be adjusted in accordance with the wire.

It is an objective of the present disclosure to provide a wire harness that restricts rotation of a wire in a holder.

A wire harness according to the present disclosure includes a tubular member, a wire member inserted through the tubular member, and a tubular holder holding the wire member in the tubular member. The holder includes a first segment and a second segment that are separated by a separation plane that extends in a longitudinal direction of the holder. Each of the first segment and the second segment includes a holding portion configured to hold the wire member disposed in the holder.

The wire harness according to the present disclosure is effective in restricting rotation of a wire in the holder.

DETAILED DESCRIPTION

Description of Embodiments of Present Disclosure

The embodiments of the present disclosure will now be described.

In some embodiments of the present disclosure, a wire harness includes a tubular member, a wire member inserted through the tubular member, and a tubular holder holding the wire member in the tubular member. The holder includes a first segment and a second segment that are separated by a separation plane that extends in a longitudinal direction of the holder. Each of the first segment and the second segment includes a holding portion configured to hold the wire member disposed in the holder.

With this structure, the wire member located in the holder is sandwiched and held by the holding portions disposed on each of the first segment and the second segment. This restricts rotation of the wire member in the holder. In addition, a jig for bundling wire members is not necessary. This simplifies the structure of the wire harness. Furthermore, as compared to a case in which the jig for bundling the wire members is adjusted, the holder readily deals with wire members that have different cross-sectional shapes. Thus, the holder has a high versatility.

In some embodiments, each of the first segment and the second segment includes two ends in the longitudinal direction of the holder, and in each of the first segment and the second segment, the holding portion is disposed on each of the two ends.

With this structure, rotation of the wire member is restricted at the two ends in the longitudinal direction of the holder.

In some embodiments, the holder is cylindrical. Each of the first segment and the second segment includes a semi-cylindrical body and the holding portion projecting from an inner surface of the semi-cylindrical body.

With this structure, the cylindrical holder includes the first segment and the second segment. Thus, the wire member is readily covered by the holder.

In some embodiments, the wire member is one of wire members. The wire members are inserted through the holder. In the first segment and the second segment, the holding portions are disposed to sandwich the wire members in a direction orthogonal to a direction in which the wire members are arranged next to one another.

This structure restricts rotation of each of the wire members.

In some embodiments, as viewed in the longitudinal direction of the holder, the holding portion is V-shaped.

In some embodiments, the wire member includes a first wire, a second wire, and a joint portion joining the first wire and the second wire. The joint portion is disposed in the holder.

With this structure, the holder stably holds the first wire, the second wire, and the joint portion of the wire member. This appropriately restricts movement of the joint portion in the holder. Thus, the joined state of the first wire and the second wire is appropriately maintained.

Detailed Description of Embodiments of Present Disclosure

Specific examples of a wire harness according to the present disclosure will be described below with reference to the drawings. In the drawings, components may be partially exaggerated or simplified to facilitate understanding. The dimensional ratio of the components may differ between the drawings. In this specification, “orthogonal” is not limited to being exactly orthogonal and includes being generally orthogonal within the scope in which the operation and advantages of the embodiments are obtained. The present disclosure is not limited to those exemplified and is shown by the scope of the claims. It is intended to include all modifications within the meaning and range equivalent to the scope of the claims.

An embodiment of a wire harness will now be described with reference toFIGS.1to6.

As shown inFIG.1, the wire harness10electrically connects electric devices M1and M2. Alternatively, the wire harness10may be configured to connect three or more electric devices.

In an example, the wire harness10is mounted on a vehicle11such as a hybrid vehicle, an electric vehicle, or the like. The wire harness10includes one or more (in the present embodiment, two) wire members20that electrically connect the electric device M1and the electric device M2. In an example, the wire harness10includes a tubular member30and tubular exterior members41. The wire members20extend through the tubular member30. The tubular exterior members41surround the wire members20extending out of the tubular member30. In an example, the wire harness10includes holders50arranged on ends31and32of the tubular member30in the longitudinal direction (axial direction). The tubular member30and the exterior members41protect the wire members20, accommodated in the tubular member30and the exterior members41, from flying objects and waterdrops. In an example, the wire harness10has a passage that is bent in two dimensions or three dimensions.

In an example, the wire harness10is laid out so that a portion of the wire harness10in the longitudinal direction extends under the floor of the vehicle11from the electric device M1to the electric device M2. One end of each wire member20is connected to the electric device M1. The other end of the wire member20is connected to the electric device M2. In an example, the electric device M1is an inverter arranged toward the front of the vehicle11, and the electric device M2is a high-voltage battery arranged toward the rear of the vehicle11from the electric device M1. In an example, the inverter is connected to a wheel driving motor that is used as a power source for the vehicle to travel. The inverter generates an alternating current power from a direct current power of the high-voltage battery and supplies the alternating current power to the motor. The high-voltage battery is configured to supply a voltage of, for example, 100 V or higher.

As shown inFIG.3, each wire member20includes a first wire21and a second wire24electrically connected to the first wire21. In an example, the first wire21is a flexible wire, and the second wire24is a rigid wire. In the present embodiment, the wire member20is obtained by electrically connecting the first wire21and the second wire24, which differ in type, in the longitudinal direction of the wire member20. Alternatively, the wire member20may be obtained by electrically connecting a first wire21and a second wire24that are the same type. The flexible wire is more flexible than the rigid wire. The flexible wire has a higher bendability than the rigid wire. In an example, the rigid wire has a greater flexural rigidity than the flexible wire. In an example, the rigid wire is rigid enough to retain a shape conforming to the laid out passage of the wire member20. In an example, when mounted on the vehicle11(refer toFIG.1), the rigid wire is rigid enough to maintain a straight or bent state of the rigid wire when the vehicle11, for example, vibrates. In an example, when the rigid wire is laid out in a curved passage, the rigid wire is bent and retains the bent shape.

As shown inFIGS.1and3, the wire member20includes a joint portion27that joins each first wire21and the second wire24and a covering member28that covers the circumference of the joint portion27. The first wires21are connected to two opposite ends of the second wire24in the longitudinal direction. In the present embodiment, the wire member20includes a longitudinal intermediate portion formed of the second wire24, and the wire member20includes two longitudinal ends formed of the first wires21. The first wires21and the second wire24are, for example, high-voltage wires that may be used with high voltage and high current. In an example, each of the first wires21and the second wire24may be a shielded wire having an electromagnetic shielding structure and an unshielded wire that does not have an electromagnetic shielding structure. In the present embodiment, the first wires21and the second wire24are unshielded wires.

First Wire21

As shown inFIG.3, the first wire21includes a core wire22formed of metal strands and an insulation covering23that covers the circumference of the core wire22. The core wire22may be, for example, a stranded wire obtained by twisting a plurality of metal strands or a braided member obtained by braiding a plurality of metal strands into the form of a tube. In the present embodiment, the core wire22is a stranded wire. The material of the core wire22may be, for example, copper-based or aluminum-based metal.

When the core wire22is cut along a plane orthogonal to the longitudinal direction, the cross section of the core wire22, that is, the transverse cross section of the core wire22, may have any shape. The transverse cross-sectional shape of the core wire22may be, for example, a circle, a semicircle, a polygon, a square, or an oblong. In the present embodiment, the transverse cross-sectional shape of the core wire22is a circle.

In an example, the insulation covering23entirely covers the circumference of the core wire22in the circumferential direction. In an example, the insulation covering23is formed from an insulation material such as a synthetic resin. In an example, the material of the insulation covering23may be a polyolefin-based resin such as cross-linked polyethylene or a cross-linked polypropylene. In an example, the insulation covering23may be formed by performing extrusion (extrusion covering) on the core wire22.

In an example, the second wire24includes a single core wire25formed of a single conductor and an insulation covering26covering the circumference of the single core wire25. The single core wire25may be, for example, a rod-shaped conductor formed of a single metal rod having a solid inner structure or a tubular conductor having a hollow inner structure. In the present embodiment, the single core wire25is a rod-shaped conductor. The material of the single core wire25may be, for example, copper-based or aluminum-based metal. In an example, the material of the single core wire25may be the same type as the material of the core wire22or may differ from the material of the core wire22. The single core wire25is formed through, for example, extrusion. The single core wire25may have any transverse cross-sectional shape. In the present embodiment, the transverse cross-sectional shape of the single core wire25is a circle.

In an example, the insulation covering26entirely covers the circumference of the single core wire25in the circumferential direction. In an example, the insulation covering26is formed from an insulation material such as a synthetic resin. The material of the insulation covering26may be, for example, a polyolefin-based resin such as cross-linked polyethylene or a cross-linked polypropylene. In an example, the insulation covering26may be formed by performing extrusion on the single core wire25. The insulation covering26may be, for example, formed of a heat-shrink tube or a rubber tube.

The joint portion27joins the core wire22and the single core wire25. More specifically, the insulation covering23is removed from a longitudinal end of the first wire21by a fixed length from the terminal of the first wire21to expose the end of the core wire22. Also, the insulation covering26is removed from a longitudinal end of the second wire24by a fixed length from the terminal of the second wire24to expose the end of the single core wire25. In the joint portion27, the end of the core wire22exposed from the insulation covering23is joined to the end of the single core wire25exposed from the insulation covering26. In an example, in the joint portion27, the core wire22and the single core wire25are disposed one on the other in a radial direction, that is, a direction intersecting the longitudinal direction of the core wire22and the single core wire25, and joined to each other. The process of joining the core wire22and the single core wire25is not particularly limited. In an example, the core wire22and the single core wire25may be joined by ultrasonic welding or laser beam welding.

The covering member28covers the circumference of the joint portion27. In an example, the covering member28is elongated and tubular. In an example, the covering member28covers the core wire22, exposed from the insulation covering23, and the single core wire25, exposed from the insulation covering26. In an example, the covering member28extends over an end of the insulation covering23and an end of the insulation covering26. In an example, one end of the covering member28covers the outer circumferential surface of the end of the insulation covering23, and the other end of the covering member28covers the outer circumferential surface of the end of the insulation covering26. The covering member28entirely surrounds the circumference of the first wire21and the circumference of the second wire24in the circumferential direction. In an example, the covering member28maintains the electrical insulation of the joint portion27, and the core wire22and the single core wire25, which are exposed from the insulation coverings23and26. In an example, the covering member28also protects the joint portion27, and the core wire22and the single core wire25, which are exposed from the insulation coverings23and26.

The covering member28may be, for example, a shrinkable tube, a rubber tube, a resin mold, a hot melt adhesive, or a tape member. In the present embodiment, the covering member28is a heat-shrink tube. In an example, the material of the covering member28may be a synthetic resin, the main component of which is a polyolefin-based resin such as cross-linked polyethylene or a cross-linked polypropylene.

In an example, the second wire24is disposed in the tubular member30. In an example, the entire length of the second wire24is disposed in the tubular member30in the longitudinal direction of the second wire24. In an example, the joint portion27is disposed in the tubular member30. In an example, a longitudinal end of the first wire21is disposed in the tubular member30. The first wire21is drawn out of the tubular member30from the end31of the tubular member30. Although not shown, in the same manner, at the end32(refer toFIG.1) of the tubular member30, the joint portion27, which joins the longitudinal end of the first wire21and the longitudinal end of the second wire24, is disposed in the tubular member30. Also, the first wire21is drawn out of the tubular member30from the end32of the tubular member30.

In the present embodiment, the tubular member30has the form of an elongated cylindrical tube. In an example, the tubular member30is disposed in a longitudinal intermediate portion of the wire harness10. In an example, a longitudinal intermediate portion of the wire member20is accommodated in the tubular member30. In an example, the tubular member30entirely surrounds the circumference of the wire member20in the circumferential direction. The tubular member30may be, for example, a metal pipe, a resin pipe, a corrugated resin tube, a waterproof rubber cover, or a combination of these. The material of the metal pipe may be, for example, an aluminum-based or copper-based metal material. The material of the resin pipe and the corrugated tube may be, for example, a conductive resin material or a non-conductive resin material. The resin material may be, for example, a synthetic resin such as polyolefin, polyamide, polyester, or an acrylonitrile butadiene styrene (ABS) resin. In the present embodiment, the tubular member30is a metal pipe.

As shown inFIGS.2and4, the tubular member30includes a through hole33. The through hole33extends through the tubular member30from an outer surface34to an inner surface35of the tubular member30. In the present embodiment of the tubular member30, the ends31and32each include two through holes33. The two through holes33are located in different positions in the circumferential direction of the tubular member30. In the present embodiment, the through holes33are separated at an interval of 180 degrees in the circumferential direction of the tubular member30.

As shown inFIG.1, the exterior members41are elongated and tubular. In an example, the exterior members41are disposed on two longitudinal ends of the wire harness10. In an example, a longitudinal end of the wire member20, that is, an end of the wire member20drawn out from the tubular member30, is accommodated in the exterior member41. In an example, the exterior member41entirely surrounds the circumference of the wire member20in the circumferential direction. In an example, the exterior member41entirely surrounds the circumference of the first wire21in the circumferential direction along the longitudinal direction of the wire members20. The exterior member41may be, for example, a corrugated tube or a waterproof cover.

When the holder50is inserted into the tubular member30, the holder50is coupled to the ends31and32of the tubular member30. The holder50holds a plurality of wire members20. More specifically, the holders50holds the wire members20that are inserted through the tubular member30. In an example, the holder50is formed from a synthetic resin. The material of the holder50may be, for example, a synthetic resin such as polyolefin, polyamide, polyester, or an acrylonitrile butadiene styrene (ABS) resin. The holder50sets layout positions (arrangement) of the wire members20and maintains the layout positions. The holder50sets the layout positions of the wire members20with respect to the tubular member30and maintains the layout positions. When the holder50is disposed in the tubular member30, the holder50protects the wire members20from an edge of the tubular member30.

FIG.2shows the holder50that is disposed on the end31of the tubular member30and the wire members20that are inserted through the holder50. The state at the end32of the tubular member30is the same as that at the end31and thus will not be shown and described.

As shown inFIG.2, when the holder50is inserted into the tubular member30, the holder50is coupled to the end31of the tubular member30. The holder50includes a first end51and a second end52, which are located at opposite sides of the holder50. The second end52of the holder50is inserted in an inner side of the tubular member30. The holder50is coupled to the tubular member30so that a portion including the first end51is exposed from the tubular member30.

The holder50is cylindrical. Two wire members20are inserted through the holder50. As shown inFIG.3, each wire member20includes a joint portion27that joins the first wire21and the second wire24. The holder50covers the joint portion27of each wire member20.

As shown inFIGS.4to6, the holder50includes a first segment60A and a second segment60B. The first segment60A and the second segment60B have a shape of the cylindrical holder50that is separated by a separation plane extending in the longitudinal direction of the holder50. Thus, each of the first segment60A and the second segment is semi-cylindrical. In the present embodiment, the separation plane extends through a center axis O1of the tubular holder50.

The holder50includes a hinge54that joins the first segment60A and the second segment60B. In an example, the holder50is a single-piece component in which the first segment60A, the second segment60B, and the hinge54are formed integrally. The hinge54is a thin plate. The first segment60A and the second segment60B are configured to pivot relative to each other about the hinge54. The holder50is configured to pivot the first segment60A relative to the second segment60B to obtain the closed state shown inFIG.2. Also, as shown inFIG.6, the holder50is configured to obtain an open state in which the inner surfaces63A and63B of the first segment60A and the second segment60B are exposed. When the holder50changes the first segment60A and the second segment60B from the open state to the closed state, the holder50is coupled to the wire members20so as to cover the wire members20from an outer side.

As shown inFIGS.2and6, the first segment60A includes a first engagement portion55located at a side opposite to the hinge54in the circumferential direction. The second segment60B includes a second engagement portion56located at a side opposite to the hinge54in the circumferential direction. The second engagement portion56is configured to engage the first engagement portion55. When the first engagement portion55engages the second engagement portion56, the first segment60A the second segment maintain the tubular shape.

Each of the first segment60A and the second segment60B includes a lock portion81. The lock portion81is arranged in accordance with the through hole33of the tubular member30. The lock portion81includes a flexible piece82and a fixing projection83. The flexible piece82extends toward the first end51in the longitudinal direction of the holder50. Each of the first segment60A and the second segment60B includes a U-shaped slit84. The flexible piece82is defined by a portion of the first segment60A and the second segment60B surrounded by the slit84. The flexible piece82is flexible in a radial direction of the holder50. The fixing projection83projects from the flexible piece82to an outer side of the holder50. When the holder50is inserted into the tubular member30, the fixing projection83is fitted into the through hole33of the tubular member30. Thus, the lock portion81fixes the holder50to the tubular member30.

As shown inFIGS.4to6, the first segment60A and the second segment60B include bodies61A and61B, respectively. Each of the bodies61A and61B is semi-cylindrical. The bodies61A and61B respectively include outer surfaces62A and62B and the inner surfaces63A and63B.

The first segment60A includes a first holding portion64A and a second holding portion65A. The second segment60B includes a first holding portion64B and a second holding portion65B. The first holding portions64A and64B and the second holding portions65A and65B are arranged to hold the wire members20in the holder50.

The first holding portions64A and64B are disposed on the first ends51A and51B of the first segment60A and the second segment60B. The second holding portions65A and65B are disposed on the second ends52A and52B of the first segment60A and the second segment60B. The first holding portion64A and the second holding portion65A of the first segment60A project from the inner surface63A of the body61A of the first segment60A. In the same manner, the first holding portion64B and the second holding portion65B of the second segment60B project from the inner surface63B of the body61B of the second segment60B.

As shown inFIG.4, the first holding portions64A and64B are formed so a s to sandwich the circumferential surfaces of the two wire members20in the holder50from opposite sides. As viewed in a direction extending along the center axis O1of the holder50, the first holding portions64A and64B are disposed to sandwich the two wire members20in the holder50in a direction that is orthogonal to a direction (vertical direction inFIG.4) in which the two wire members20are arranged next to one another. As shown inFIG.3, each wire member20includes the first wire21and the second wire24. As shown inFIG.4, the first holding portions64A and64B are disposed to sandwich the circumferential surfaces of the two first wires21from opposite sides. Each of the first holding portions64A and64B includes two contact parts66A and66B configured to contact the two wire members20(first wire21) and recesses67A and67B recessed toward a radially outer side of the holder50between the two contact parts66A and66B. The first holding portions64A and64B having the above structure are V-shaped.

As shown inFIG.5, the second holding portions65A and65B are formed so as to sandwich the two wire members20in the holder50. As viewed in a direction extending along the center axis O1of the holder50, the second holding portions65A and65B are disposed to sandwich the wire members20in the holder50in a direction orthogonal to the arrangement direction (vertical direction inFIG.5) of the two wire members20. As shown inFIG.5, the second holding portions65A and65B are disposed to sandwich the circumferential surfaces of the two second wires24from opposite sides. Each of the second holding portions65A and65B includes two contact parts68A and68B configured to contact the two wire members20(second wire24) and recesses69A and69B recessed toward a radially outer side of the holder50between the two contact parts68A and68B. The second holding portions65A and65B having the above structure are V-shaped.

Operation and Advantages

The operation and advantages of the wire harness10of the present embodiment will now be described.

(1) The wire harness10includes the tubular member30, the wire members20inserted through the tubular member30, and the tubular holders50holding the wire members20in the tubular member30. Each holder50includes the first segment60A and the second segment60B, which are separated by the separation plane extending in the longitudinal direction of the holder50. The first segment60A includes the holding portions64A and65A that hold the wire members20in the holder50. Also, the second segment60B includes the holding portions64B and65B that hold the wire members20in the holder50.

In the wire harness10, the wire members20are sandwiched and held by the holding portion64A of the first segment60A and the holding portion64B of the second segment60B in the holder50. Also, the wire members20are sandwiched and held by the holding portion65A of the first segment60A and the holding portion65B of the second segment60B in the holder50. This restricts rotation of the wire members20in the holder50. In addition, a jig for bundling the wire members20is not necessary. This simplifies the structure of the wire harness10. Furthermore, the wire members20having different cross-sectional shapes are readily dealt with as compared to a case in which the jig for bundling the wire members20is adjusted. Thus, the holder50has a high versatility.

(2) The first holding portions64A and64B are disposed on the first ends51A and51B of the first segment60A and the second segment60B. The second holding portions65A and65B are disposed on the second ends52A and52B of the first segment60A and the second segment60B. The holding portions64A,64B,65A, and65B are disposed on the opposite ends51A,51B,52A, and52B of the first segment60A and the second segment60B. Thus, rotation of the wire members20is restricted at the opposite ends51and52in the longitudinal direction of the holder50.

(3) The first segment60A includes the semi-cylindrical body61A and the holding portions64A and65A projecting from the inner surface63A of the body61A. The second segment60B includes the semi-cylindrical body61B and the holding portions64B and65B projecting from the inner surface63B of the body61B. The cylindrical holder50includes the first segment60A and the second segment60B. Thus, the wire members20are readily covered by the holder50.

(4) As viewed in a direction extending along the center axis O1of the holder50, the holding portions64A and65A of the first segment60A and the holding portions64B and65B of the second segment60B are disposed to sandwich the two wire members20in a direction orthogonal to the direction in which the two wire members20are arranged next to one another. This restricts rotation of each of the two wire members20.

(5) The holder50includes the hinge54joining the first segment60A and the second segment60B. The first segment60A and the second segment60B change from the open state to the closed state about the hinge54. Thus, the wire members20are readily disposed in the holders50.

(6) The wire member20includes the first wire21, the second wire24, and the joint portion27joining the first wire21and the second wire24. Thus, the holder50stably holds the first wire21, the second wire24, and the joint portion27of the wire member20. This appropriately restricts movement of the joint portion27in the holder50. Thus, the joined state of the first wire21and the second wire24is appropriately maintained.

(7) The circumference of the joint portion27is covered by the covering member28. The holder50is formed to cover the joint portion27. Thus, the holder50, which is inserted into the tubular member30, hinders contact of the tubular member30with the covering member28, which covers the joint portion27. If the covering member28contacts the tubular member30, the covering member28may wear due to vibration or the like. In the present embodiment, the holder50covers the joint portion27and the covering member28, which covers the joint portion27. This limits the wearing of the covering member28. Thus, the durability of the covering member28is improved, Accordingly, the durability of the wire member20is improved.

Modified Examples

The embodiment described above may be modified as follows. The embodiment and the following modified examples can be combined as long as the combined modified examples remain technically consistent with each other.

As shown inFIG.7, a wire harness110may be configured to electrically connect electric devices M1, M2, M3, and M4. In an example, the wire harness110is mounted on a vehicle11such as a hybrid vehicle, an electric vehicle, or the like. The wire harness110includes the wire members20and one or more (in this modified example, two) wire members120that electrically connects the electric device M3and the electric device M4. The wire members120and the wire members20are inserted through the tubular member30and the holders50. In an example, the wire harness110includes a tubular exterior member42surrounding the wire members120that are drawn out of the tubular member30. The tubular member30and the exterior members41and42protect the wire members20and120, accommodated in the tubular member30and the exterior members41and42, from flying objects and waterdrops.

As shown inFIG.8, the wire member120is a flexible wire. In an example, the wire member120is a low-voltage wire. The wire member120may be, for example, a shielded wire having an electromagnetic shielding structure or an unshielded wire that does not have an electromagnetic shielding structure. In this modified example, the wire member120is an unshielded wire. In the same manner as the first wire21of the above embodiment, the wire member120is more flexible than the rigid wire. In an example, the wire member120has a higher bendability than the rigid wire. The wire member120includes a core wire121formed of metal strands and an insulation covering122that covers the circumference of the core wire121. The core wire121may be, for example, a stranded wire or a braided member. The core wire121is a stranded wire. The material of the core wire121may be, for example, copper-based or aluminum-based metal. The core wire121may have any transverse cross-sectional shape. The transverse cross-sectional shape of the core wire121is a circle.

As shown inFIG.8, the wire members120may be disposed in the recesses67A and67B of the first holding portions64A and64B in the holder50. Thus, the holder50restricts rotation of the wire members120together with the wire members20. In addition, the holder50protects the wire members120together with the wire members20from the edge of the end of the tubular member30. As shown inFIG.5, the holder50includes the recesses69A and69B in the second holding portions65A and65B. The wire members120are disposed in the recesses69A and69B. Thus, the second holding portions65A and of the holder50restrict rotation of the wire members120.

The recesses67A and67B may be omitted from the first holding portions64A and64B. The recesses69A and69B may be omitted from the second holding portions65A and65B.

In the embodiment, the holders50are disposed on the longitudinal ends31and32of the tubular member30. However, there is no limitation to such a structure. In an example, the holder50may be disposed on only one of the longitudinal ends of the tubular member30.

In the embodiment, the joint portions27are disposed at different positions, in the longitudinal direction, of the wire members20. However, there is no limitation to such a structure. In an example, the joint portions27may be disposed at the same position, in the longitudinal direction, of the wire members20.

In the embodiment, the number of the wire members20and120inserted through the holders50is not particularly limited. The number of the wire members20and120may be changed in accordance with the specifications of the vehicle11. The number of the wire members20may be, for example, one or three or more. The number of the wire members120may be, for example, one or three or more.

The tubular member30of the embodiment is not limited to a member formed of a single material, that is, metal or resin. In an example, the tubular member30may be a combined member obtained by laminating or embedding a conductive shield layer in a nonmetal pipe body.

In the embodiment, an exterior member having a branching passage may be disposed between the tubular member30and the exterior member41. Such an exterior member may be, for example, a waterproof rubber cover.

Although not particularly described in the embodiment, an electromagnetic shield member may be disposed in the tubular member30. The electromagnetic shield member is disposed, for example, to surround the wire members20as a bundle. In an example, the electromagnetic shield member is disposed between the inner circumferential surface of the tubular member30and the outer circumferential surface of the wire member20. The electromagnetic shield member may be, for example, a flexible braided wire or a metal foil.

The positional relationship of the electric devices M1and M2(M1to M4) in the vehicle11is not limited to that of the embodiment and may be changed in accordance with the configuration of the vehicle.

In the embodiment, a portion of the holder50including the first end51projects from the tubular member30and may form a projection portion. Tape may be wrapped around the projection portion of the holder50and the wire members20so that the wire members20are fixed to the holder50.

As shown inFIGS.2,4and5, when the first segment60A and the second segment60B are in the closed state, the holder50may be cylindrical in which a circumferential wall of the first segment60A and a circumferential wall of the second segment60B are joined together to form a cylindrical circumference that extends continuously around an entire circumference of the holder50.

Each of the holding portions64A,64B,65A, and65B may be referred to as a radially inward projection of the holder50, which projects inwardly in the radial direction and directed toward the center axis O1of the holder50as shown in a cross-sectional view of the holder50. As shown inFIG.4, when viewed from a direction along the center axis O1of the holder50, a radially inner contour of the first holding portion64A includes two planar parts, each defining or serving as the contact part66A and each extending parallel to the radial direction of the holder50, and a concave part located between and continuous with the two planar parts (i.e., the two contact parts66A) of the radially inward projection and defining or serving as the recess67A. As shown inFIGS.4and5, the radially inward contour of the first holding portion64B, the radially inward contour of the second holding portion65A, and the radially inward contour of the second holding portion65B may have the same shape as the radially inward contour of the first holding portion64A.

As shown inFIGS.3and4, the first holding portion64A and the first holding portion64B may be arranged in the same position in the longitudinal direction of the holder50. When the first segment60A and the second segment60B are in the closed state, the two planar parts of the contact part66A and the two planar parts of the contact part66B may face and be parallel to each other. As shown inFIGS.3and5, the second holding portion65A and the second holding portion65B may be arranged in the same manner as the first holding portion64A and the first holding portion64B.

As shown inFIG.4, when the first segment60A and the second segment60B are in the closed state, the distance between the contact part66A of the first holding portion64A and the contact part66B of the first holding portion64B may be smaller than the outer diameter of the wire member20.

All aspects of the embodiments in the present disclosure should be considered to be illustrative and non-restrictive. The present disclosure is not limited to those exemplified and is shown by the scope of the claims. It is intended to include all modifications within the meaning and range equivalent to the scope of the claims.
