Detailed Description

[ description of embodiments of the present disclosure ]

First, embodiments of the present disclosure will be described.

[1] The wire harness of the present disclosure has: an electric wire; a terminal electrically connected to the electric wire; a holder attached to the electric wire; and a temperature sensor member fixed to the holding body and capable of measuring a temperature of the terminal, the holding body having a positioning portion that performs positioning of the holding body in a longitudinal direction of the electric wire.

According to this structure, the positioning portion for positioning the holding body in the longitudinal direction of the electric wire is provided in the holding body to which the temperature sensor member is fixed. Therefore, when the holder is attached to the electric wire, the holder can be easily positioned with respect to the electric wire in the longitudinal direction of the electric wire. Further, the positioning of the temperature sensor member with respect to the electric wire can be easily performed in the longitudinal direction of the electric wire. Thus, the workability of assembling the wire harness can be improved.

[2] Preferably, the electric wire has: a core wire having conductivity; and an insulating coating portion that coats an outer periphery of the core wire and has insulation, wherein an end portion in a longitudinal direction of the core wire has an exposed portion exposed from the insulating coating portion, the electric wire has a step formed by an outer peripheral surface of the exposed portion, a 1 st end surface in the longitudinal direction of the insulating coating portion, and an outer peripheral surface of the insulating coating portion, and the positioning portion is engageable with the 1 st end surface in the longitudinal direction of the electric wire.

According to this configuration, when the holder is attached to the electric wire, the positioning portion is engaged with the 1 st end surface of the insulating cover portion, so that the holder can be easily positioned with respect to the electric wire in the longitudinal direction of the electric wire.

[3] Preferably, the terminal is electrically connected to the exposed portion, and the positioning portion is provided between the 1 st end face and the terminal in a longitudinal direction of the electric wire.

According to this structure, the positioning portion of the holder to which the temperature sensor member is fixed is provided between the 1 st end surface of the insulating cover and the terminal. Therefore, the holding body can be provided in the vicinity of the terminal. Further, the temperature sensor member can be provided in the vicinity of the terminal. Thereby, the temperature sensor member can appropriately detect a temperature change of the terminal provided in the vicinity of the temperature sensor member. In other words, the accuracy of temperature detection of the terminals in the temperature sensor member can be improved.

[4] Preferably, a part of the temperature sensor member is provided so as to overlap the positioning portion in the radial direction of the electric wire.

According to this structure, the temperature sensor member can be provided in the vicinity of the terminal. Thereby, the temperature sensor member can more appropriately detect the temperature change of the terminal. In other words, the accuracy of temperature detection of the terminals in the temperature sensor member can be further improved.

[5] Preferably, the holder has: a holding portion that holds the temperature sensor member; and a restricting portion that protrudes from the holding portion and restricts relative movement of the holding body in a circumferential direction of the electric wire.

According to this structure, the regulating portion that regulates the relative movement of the holding body in the circumferential direction of the electric wire is provided to the holding body. Therefore, misalignment of the holder with respect to the electric wire can be suppressed in the circumferential direction of the electric wire, and the positional accuracy of the holder with respect to the electric wire can be improved. Further, misalignment of the temperature sensor member with respect to the electric wire can be suppressed in the circumferential direction of the electric wire, and positional accuracy of the temperature sensor member with respect to the electric wire can be improved.

[6] Preferably, the restriction portion has: a tubular restricting body portion having an inner surface along an outer peripheral surface of the electric wire; and an insertion port that opens in a direction orthogonal to the axial direction of the regulating body portion and extends over the entire axial length of the regulating body portion, wherein an opening width of the insertion port is smaller than an outer diameter of the electric wire.

According to this structure, the insertion port of the restricting portion is opened in a direction orthogonal to the axial direction of the restricting body portion, and extends over the entire axial length of the restricting body portion. Thus, after the terminal is attached to the end portion of the electric wire in the longitudinal direction, the restriction portion and the holder having the restriction portion can be attached to the electric wire from the insertion port. In this way, the holding body can be mounted on the electric wire, and thus the workability of the assembly of the wire harness can be improved. In addition, the opening width of the insertion opening is formed smaller than the outer diameter of the electric wire. Therefore, after the regulating body portion is attached to the outer periphery of the electric wire, the relative movement of the regulating body portion and the holder with respect to the electric wire can be appropriately suppressed.

[7] Preferably, there is a 1 st adhesive that adheres the temperature sensor member to the holder, the 1 st adhesive being a thermosetting resin.

According to this structure, the temperature sensor member is integrated with the holder by the thermosetting resin as the 1 st adhesive. Therefore, the wire harness having the electric wire, the terminal, the holder, and the temperature sensor member can be suitably applied to, for example, a wire harness for charging that can be brought to a high temperature.

[8] Preferably, the temperature sensor member includes a sensor body portion and a signal line led out from the sensor body portion, and further includes a tubular covering member covering the sensor body portion and a connection portion between the electric line and the terminal in a longitudinal direction of the electric line.

According to this structure, the sensor body and the connection portion between the electric wire and the terminal are covered with the tubular covering member. Therefore, the sensor body portion and the connection portion of the electric wire and the terminal can be restrained from directly contacting other members. This can suppress abrasion and the like due to contact between the sensor body and the connection portion between the wire and the terminal and other members. As a result, the durability of the sensor body portion can be improved, and the durability of the connection portion of the electric wire and the terminal can be improved.

[9] Preferably, the coating member has a tubular heat shrink tube and a 2 nd adhesive provided on an inner peripheral surface of the heat shrink tube, one end portion in an axial direction of the heat shrink tube is adhered to an outer peripheral surface of the electric wire by the 2 nd adhesive, and the other end portion in the axial direction of the heat shrink tube is adhered to the outer peripheral surface of the terminal by the 2 nd adhesive.

According to this structure, the gap between the inner peripheral surface of the one end portion in the axial direction of the heat shrink tube and the outer peripheral surface of the electric wire is blocked by the 2 nd adhesive, and the gap between the inner peripheral surface of the other end portion in the axial direction of the heat shrink tube and the outer peripheral surface of the terminal is blocked by the 2 nd adhesive. This can prevent liquid such as water from entering the interior of the sheathing member from both axial end portions of the sheathing member.

[10] Preferably, the terminal is provided in a connector mounted on the vehicle, the connector being electrically connectable to an external connector, the external connector being connected to an external power supply device.

According to this configuration, terminals are provided in the connector electrically connected to the external connector and the external power supply device. Since a large current flows through the terminal in this case, the temperature of the terminal is liable to rise. The temperature of such a terminal can be measured by the temperature sensor member. Therefore, by the temperature sensor member, abnormal heat generation in the terminal, for example, can be appropriately detected.

That is, the rear end portion of the core wire 21 has an exposed portion 23 exposed from the insulating coating portion 22. For example, the rear end portion of the core wire 21, that is, the exposed portion 23 is exposed from the insulating coating portion 22 by peeling the insulating coating portion 22 of a predetermined length from the tip end of each electric wire 20 at the rear end portion of the electric wire 20.

The restricting portion 50 protrudes from, for example, the 2 nd face 42B of the base portion 42. The restricting portion 50 is, for example, continuously formed integrally with the base portion 42. The restricting portion 50 is attached to, for example, an outer peripheral surface of the electric wire 20. The restricting portion 50 is attached to, for example, the outer peripheral surface of the insulating coating portion 22 of the electric wire 20. As shown in fig. 3, the restricting portion 50 is attached to, for example, the outer peripheral surface of the rear end portion of the insulating cover 22. The restricting portion 50 is provided locally in the longitudinal direction of the base portion 42, for example. The restricting portion 50 is provided, for example, at a middle portion in the longitudinal direction of the base 42. The restricting portion 50 is provided, for example, apart from the 3 rd surface 42C of the base 42 in the longitudinal direction of the base 42.

As shown in fig. 5, the restricting portion 50 includes, for example: a tubular regulating body 51 having an inner surface along the outer peripheral surface of the insulating coating 22; and an insertion port 52 provided in a part of the circumferential direction of the restricting body 51 and opening in a direction orthogonal to the axial direction of the restricting body 51. Here, the axial direction of the restricting body 51 is a direction in which the central axis of the restricting body 51 extends. The axial direction of the regulating body 51 of the present embodiment extends parallel to the longitudinal direction of the electric wire 20.

The regulating body 51 covers a part of the outer periphery of the insulating cover 22 in the circumferential direction of the insulating cover 22, for example. The regulating body 51 is formed in a cylindrical shape, for example, in which a part of the circumferential direction of the insulating coating portion 22 coats the outer periphery of the insulating coating portion 22. The cross-sectional shape of the restricting body portion 51 is formed in a C-shape as a whole. The restricting body 51 covers a range larger than half of the outer periphery of the insulating cover 22, for example. That is, the regulating body 51 covers a range larger than half of the entire circumference of the insulating cover 22 in the outer circumference of the insulating cover 22.

The restricting body 51 includes a pair of arms 53 and 54 extending from the 2 nd surface 42B of the base 42, a 1 st end 53A as a distal end of the arm 53, and a 2 nd end 54A as a distal end of the arm 54. The arm portions 53 and 54 extend from the 2 nd surface 42B along the outer peripheral surface of the electric wire 20 in a curved manner. The pair of arm portions 53 and 54 extend in a curved manner in directions opposite to each other in the radial direction of the electric wire 20. The inner surfaces of the arm portions 53 and 54 have cross-sectional shapes along the outer peripheral surface of the insulating coating 22. The inner surfaces of the arm portions 53 and 54 are formed in an arc shape, for example, in cross-section. The inner surfaces of the arm portions 53 and 54 are, for example, in close contact with the outer peripheral surface of the wire 20.

The 1 st end 53A and the 2 nd end 54A are both end portions of the restricting body 51 in the circumferential direction. The 1 st end 53A and the 2 nd end 54A are disposed on opposite sides from each other in the circumferential direction of the restricting body portion 51. The 1 st end 53A and the 2 nd end 54A are provided so as to be separated from each other with the insertion port 52 therebetween in the circumferential direction of the restricting body 51. In other words, in the circumferential direction of the regulating body 51, the gap between the 1 st end 53A and the 2 nd end 54A is configured as the insertion port 52. In this way, the restricting portion 50 is formed in a C-shape having the insertion opening 52 at a part of the circumferential direction of the restricting body portion 51.

The insertion opening 52 extends along the axial direction of the restricting body 51 over the entire axial length of the restricting body 51, for example. That is, the insertion port 52 is formed in the following manner: open in a direction orthogonal to the axial direction of the restricting body 51, and open at both ends of the restricting body 51 in the axial direction. The insertion opening 52 is provided at a position offset from a portion connected to the base 42 in the circumferential direction of the regulating body 51, for example. The insertion opening 52 is provided at a position facing the restricting body 51 at a portion connected to the base 42, for example, in the radial direction of the restricting body 51. The opening width of the insertion opening 52, that is, the shortest distance between the 1 st end 53A and the 2 nd end 54A is, for example, smaller than the outer diameter of the electric wire 20.

When the holder 40 is attached to the outer periphery of the electric wire 20, the electric wire 20 is inserted into the insertion port 52 from a direction orthogonal to the axial direction of the restricting body 51, whereby the restricting body 51 is elastically deformed, and the opening width of the insertion port 52 is increased. When the electric wire 20 is inserted into the inside of the restricting main body portion 51, the restricting main body portion 51 is elastically restored to be returned to the original shape. Thus, the opening width of the insertion opening 52 is smaller than the outer diameter of the electric wire 20. Therefore, the restriction portion 50 is attached to the outer periphery of the electric wire 20, and the restriction portion 50 can be restrained from moving relatively in the circumferential direction of the electric wire 20. Further, the relative movement of the holder 40 in the circumferential direction of the electric wire 20 can be suppressed.

The holder 40 is attached to, for example, the outer peripheral surface of the rear end portion of the electric wire 20. The holder 40 is attached to the outer peripheral surface of the rear end portion of the insulating cover 22 in a state where the temperature sensor member 60 is fixed to the holder 41, for example. At this time, the engaging portion 47 of the positioning portion 45 is engaged in contact with the 1 st end surface 22A of the insulating cover 22. Thereby, the position of the holding body 40 with respect to the electric wire 20 is positioned in the longitudinal direction of the electric wire 20. Further, in the longitudinal direction of the electric wire 20, the temperature sensor member 60 is positioned with respect to the position of the electric wire 20.

(Structure of coating member 70)

As shown in fig. 4, the sheathing member 70 is formed in an elongated tubular shape, for example. The coating member 70, for example, coats the outer periphery of the sensor body 61 in the temperature sensor member 60. The coating member 70 coats, for example, the outer periphery of the holder 40. The coating member 70 coats, for example, the outer periphery of the exposed portion 23. The coating member 70 coats, for example, the outer periphery of the wire connection portion 31 in the terminal 30. The coating member 70, for example, coats the connection portion between the exposed portion 23 and the terminal 30. The coating member 70 is coated on the rear end surface of the exposed portion 23 from the sensor body portion 61 in the longitudinal direction of the electric wire 20, for example. The coating member 70 surrounds the outer periphery of the sensor body 61, the outer periphery of the holder 40, the outer periphery of the exposed portion 23, and the outer periphery of the wire connection portion 31 over the entire circumference. The coating member 70 has a function of maintaining electrical insulation of the connection portion between the exposed portion 23 and the terminal 30, for example. The cover member 70 has a function of waterproofing a range from the sensor main body 61 to the rear end surface of the exposed portion 23, for example. As the coating member 70, for example, a shrink tube, a rubber tube, a resin mold, a hot melt adhesive, a tape member can be used.

The coating member 70 of the present embodiment includes a heat-shrinkable tube 71 having a tubular shape and a 2 nd adhesive 72 formed on an inner peripheral surface of the heat-shrinkable tube 71.

The heat shrink tube 71 is, for example, a tube that has been formed into a cylindrical body from a state before the sensor body 61 and the connection portion between the exposed portion 23 and the terminal 30 are placed inside the coating member 70. The heat shrink tube 71 is obtained by stretching a resin member formed into an extremely thin cylindrical shape by extrusion molding into a rough cylindrical shape in a heated state, and then cooling the resin member. The heat shrinkable tube 71 thus obtained has a shape memory property of a thin tube shape which shrinks to a state before stretching when heated. As a material of the heat shrink tube 71, for example, synthetic resins such as polyolefin, polyester, nylon, silicon, and fluororesin can be used.

The 2 nd adhesive 72 is formed in a tubular shape on the inner peripheral surface of the heat shrinkage tube 71 with a uniform thickness, for example, in a state where the sensor main body 61 and the connection portion between the exposed portion 23 and the terminal 30 are placed in the interior of the covering member 70. The 2 nd adhesive 72 is formed over the entire circumferential surface and the entire axial length of the inner circumferential surface of the heat shrink tube 71, for example. As the 2 nd adhesive 72, for example, a modified polyolefin-based and polyester-based hot melt adhesive can be used.

Next, the structures of the heat shrinkable tube 71 and the 2 nd adhesive 72 after heat shrinkage will be described. The heat shrink tube 71 is formed so as to cover the rear end surface of the exposed portion 23 from the sensor body portion 61 in the longitudinal direction of the electric wire 20. The distal end portion of the heat shrink tube 71 is, for example, covered with the outer peripheral surface of the insulating cover 22 located forward of the distal end surface of the sensor body 61, and is bonded to the outer peripheral surface of the insulating cover 22 by the 2 nd adhesive 72 over the entire circumferential direction. For example, the 2 nd adhesive 72 is in close contact with the outer peripheral surface of the insulating coating portion 22 in the circumferential direction without any gap, and in close contact with the inner peripheral surface of the distal end portion of the heat shrinkage tube 71 in the circumferential direction without any gap. The rear end portion of the heat shrink tube 71 is, for example, covered with the outer peripheral surface of the terminal 30 located rearward of the rear end surface of the exposed portion 23, the intermediate portion 32 in this case, and is bonded by the 2 nd adhesive 72 over the entire circumferential periphery of the outer peripheral surface of the intermediate portion 32. For example, the 2 nd adhesive 72 is in close contact with the outer peripheral surface of the intermediate portion 32 in the circumferential direction without any gap, and in close contact with the inner peripheral surface of the rear end portion of the heat shrinkage tube 71 in the circumferential direction without any gap. Thereby, the gap between the heat shrinkage tube 71 and the insulating coating portion 22 is blocked, and the gap between the heat shrinkage tube 71 and the intermediate portion 32 is blocked. Therefore, the liquid such as water can be prevented from entering the inside of the sheathing member 70 from both end portions in the axial direction of the sheathing member 70.

The 2 nd adhesive 72 is formed, for example, at an axial middle portion of the covering member 70 so as to fill gaps between the inner peripheral surface of the heat shrinkage tube 71 and the outer peripheral surface of the holder 40, the outer peripheral surface of the sensor main body portion 61, and the outer peripheral surface of the wire connection portion 31.

Next, the operational effects of the present embodiment will be described.

(1) The wire harness 10 has: an electric wire 20; a terminal 30 electrically connected to the electric wire 20; a holder 40 attached to the electric wire 20; and a temperature sensor member 60 fixed to the holder 40 and capable of measuring the temperature of the terminal 30. The holder 40 has a positioning portion 45, and the positioning portion 45 positions the holder 40 in the longitudinal direction of the electric wire 20. According to this structure, when the holder 40 is attached to the electric wire 20, the temperature sensor member 60 can be easily positioned with respect to the electric wire 20 in the longitudinal direction of the electric wire 20. Thus, the workability of assembling the wire harness 10 can be improved.

(2) The positioning portion 45 is formed so as to be engageable with the 1 st end surface 22A of the insulating coating 22 in the longitudinal direction of the electric wire 20. According to this configuration, when the holder 40 is attached to the electric wire 20, the positioning portion 45 is engaged with the 1 st end surface 22A of the insulating coating 22, so that the holder 40 can be easily positioned with respect to the electric wire 20 in the longitudinal direction of the electric wire 20.

(3) The positioning portion 45 is provided between the 1 st end surface 22A of the insulating coating 22 and the terminal 30 in the longitudinal direction of the electric wire 20. Therefore, the holder 40 can be provided in the vicinity of the terminal 30. Further, the temperature sensor member 60 fixed to the holder 40 can be provided in the vicinity of the terminal 30. Thereby, the temperature sensor member 60 can appropriately detect the temperature change of the terminal 30 provided in the vicinity of the temperature sensor member 60. In other words, the accuracy of temperature detection of the terminal 30 in the temperature sensor member 60 can be improved.

(4) A regulating portion 50 that regulates the relative movement of the holding body 40 in the circumferential direction of the electric wire 20 is provided to the holding body 40. Therefore, misalignment of the holder 40 with respect to the electric wire 20 can be suppressed in the circumferential direction of the electric wire 20, and the positional accuracy of the holder 40 with respect to the electric wire 20 can be improved. Further, misalignment of the temperature sensor member 60 with respect to the electric wire 20 can be suppressed in the circumferential direction of the electric wire 20, and the positional accuracy of the temperature sensor member 60 with respect to the electric wire 20 can be improved. This can suppress the temperature sensor member 60 from deviating from the desired installation position, and therefore can suppress a decrease in accuracy of temperature detection of the terminal 30 in the temperature sensor member 60.

(5) By attaching the restricting portion 50 to the outer peripheral surface of the electric wire 20, the position of the holding body 40 in the circumferential direction of the electric wire 20 can be fixed. Therefore, for example, when the covering member 70 is attached, the displacement of the holder 40 with respect to the electric wire 20 can be appropriately suppressed in the circumferential direction of the electric wire 20.

(6) The restricting portion 50 is provided in the holder 40 itself for fixing the temperature sensor member 60. Therefore, the number of parts can be reduced as compared with the case where a member for fixing the holding body 40 to the outer periphery of the electric wire 20 is provided separately from the holding body 40. Further, the step of winding the tape member is not required as compared with the case where the holder 40 is fixed to the outer periphery of the electric wire 20 by the tape member or the like, and therefore, the workability of assembling the wire harness 10 can be improved. Further, in the case of using the tape member, for example, it is necessary to perform a basic evaluation as to whether the tape member does not hinder the water repellency of the 2 nd adhesive 72, but such a basic evaluation is not necessary.

(7) The insertion port 52 of the restricting portion 50 is opened in a direction orthogonal to the axial direction of the restricting body 51, and extends over the entire axial length of the restricting body 51. Thus, after the terminal 30 is attached to the end portion of the electric wire 20 in the longitudinal direction, the restriction portion 50 and the holder 40 having the restriction portion 50 can be attached to the electric wire 20 from the insertion port 52. In this way, the holding body 40 can be mounted on the electric wire 20, and thus the workability of mounting the wire harness 10 can be improved.

(8) The opening width of the insertion opening 52 is formed smaller than the outer diameter of the electric wire 20. Therefore, after the regulating body 51 is attached to the outer periphery of the electric wire 20, the relative movement of the regulating body 51 and the holder 40 with respect to the electric wire 20 can be appropriately suppressed.

(9) The temperature sensor member 60 is integrated with the holder 40 by a thermosetting resin as the 1 st adhesive 80. Therefore, the wire harness 10 including the electric wire 20, the terminal 30, the holder 40, and the temperature sensor member 60 can be suitably applied to, for example, a wire harness for charging that can be brought to a high temperature.

(10) The gap between the inner peripheral surface of the front end portion of the heat shrink tube 71 and the outer peripheral surface of the electric wire 20 is blocked by the 2 nd adhesive 72, and the gap between the inner peripheral surface of the rear end portion of the heat shrink tube 71 and the outer peripheral surface of the terminal 30 is blocked by the 2 nd adhesive 72. This can prevent liquid such as water from entering the coating member 70 from both axial end portions of the coating member 70.

(11) The terminal 30 is provided in a connector C1 electrically connected to the external connector 101 and the external power supply device 100. Since a large current flows through the terminal 30 in this case, the temperature of the terminal 30 is liable to rise. The temperature of such a terminal 30 can be measured by the temperature sensor member 60. Therefore, by the temperature sensor member 60, abnormal heat generation in the terminal 30, for example, can be appropriately detected.

(other embodiments)

The above embodiment can be modified as follows. The above-described embodiments and the following modifications can be combined with each other within a range that is not technically contradictory.

The structure of the positioning portion 45 of the above embodiment can be changed as appropriate. For example, the positioning portion 45 is not particularly limited as long as it has a structure capable of positioning the holding body 40 in the longitudinal direction of the electric wire 20.

For example, as shown in fig. 6, the positioning portion 45 may be formed so as to protrude from the 2 nd surface 42B of the base portion 42 of the holding portion 41 toward the core wire 21. The positioning portion 45 of the present modification is formed so as to be engageable with the 1 st end surface 22A of the insulating coating portion 22 in the longitudinal direction of the electric wire 20. The positioning portion 45 of the present modification may protrude rearward of the 3 rd surface 42C of the base 42.

The positioning portion 45 of the above embodiment may be formed so as to be in contact with the terminal 30. For example, the positioning portion 45 may be formed so as to contact the distal end surface of the wire connecting portion 31 of the terminal 30.

For example, the rear end portion of the sensor body 61 may be provided so as to overlap the positioning portion 45 in the radial direction of the wire 20. According to this configuration, the rear end portion of the sensor body 61 can be disposed at a position rearward of the 1 st end surface 22A of the insulating cover 22, that is, at a position closer to the terminal 30. Thereby, the temperature sensor member 60 can be disposed at a position closer to the terminal 30. As a result, the accuracy of temperature detection of the terminal 30 in the temperature sensor member 60 can be improved.

The structure of the holding portion 41 of the above embodiment can be changed as appropriate. For example, the holding portion 41 is not particularly limited as long as it has a structure capable of holding the temperature sensor member 60.

For example, the 2 nd surface 42B of the base 42 may be modified to have a shape corresponding to the outer peripheral surface of the electric wire 20. For example, the 2 nd surface 42B may be formed as a curved surface along the outer peripheral surface of the electric wire 20. For example, the cross-sectional shape of the 2 nd surface 42B may be formed in an arc shape.

The restricting wall 44 may not be connected to the pair of wall portions 43.

The limiting wall 44 may also be omitted.

At least one of the pair of wall portions 43 may be omitted.

The fixing method of the sensor body 61 to the holder 41 is not limited to the bonding of the 1 st adhesive 80, and may be other fixing methods than bonding.

The structure of the restricting portion 50 of the above embodiment can be changed as appropriate. For example, the other structure is not particularly limited as long as the regulating portion 50 has a structure capable of regulating the relative movement of the holding body 40 in the circumferential direction of the electric wire 20.

The structure of the restricting body 51 may be modified so that a part of the inner peripheral surface of the restricting body 51 does not adhere to the outer peripheral surface of the wire 20. That is, a gap may be provided between the inner peripheral surface of the restricting body 51 and the outer peripheral surface of the electric wire 20 at a part of the circumferential direction of the restricting body 51.

A plurality of restricting portions 50 may be provided.

The restricting portion 50 may be formed so as to extend over the entire length of the base portion 42 in the longitudinal direction.

The restricting portion 50 may be omitted.

The structure of the terminal 30 of the above embodiment can be changed as appropriate. For example, the intermediate portion 32 may be omitted. For example, the terminal connection portion 33 may be a male terminal.

The structure of the coating member 70 of the above embodiment can be changed as appropriate. For example, the 2 nd adhesive 72 may be omitted.

The cover member 70 may be omitted.

In the above embodiment, the number of the electric wires 20 constituting the wire harness 10 is two, but the present invention is not limited thereto. The number of the electric wires 20 may be one or three or more.

The plurality of in-vehicle devices electrically connected to the wire harness 10 are not particularly limited as long as they are electrical devices mounted on the vehicle V.

In the above embodiment, the connector C1 is embodied as a connector (charging connector) constituting the charging socket M1, but is not limited thereto. For example, the connector C1 may be embodied as a connector provided to an in-vehicle device other than the charging socket M1. The connector C1 may be embodied as a connector electrically connected to an in-vehicle device other than the charging socket M1.

The arrangement relationship between the charging receptacle M1 and the battery device M2 in the vehicle V is not limited to the above embodiment, and may be appropriately changed according to the configuration of the vehicle V.
