[0027] [Description of Embodiments of the Present Disclosure]

[0028] First, embodiments of the present disclosure will be described below.

[0029] [1] The wiring harness disclosed in the present invention comprises: a wire component having a terminal and a wire connected to the terminal, the terminal having a through hole; and a protector for accommodating the wire component, the protector comprising: a protector body having a bottom wall extending in the longitudinal direction of the wire component, two side walls protruding from both side edges of the bottom wall and opposite to each other, and an opening formed by the two side walls and opposite to the bottom wall; a bolt having a top end pointing to the side opposite to the bottom wall, protruding from the bottom wall and inserted into the through hole of the terminal; and a limiting portion covering only a portion of the wire component that is closer to the side opposite to the top end side of the terminal than the through hole in the longitudinal direction, and limiting the movement of the wire component in the protruding direction of the bolt.

[0030] According to this configuration, the movement of the electric wire member in the protruding direction is restricted inside the protector, so that the terminal can be prevented from coming off the bolt.

[0031] [2] Preferably, the restriction portion restricts movement of the electric wire member in the longitudinal direction by contacting the electric wire member.

[0032] According to this configuration, since the movement of the electric wire member in the longitudinal direction is restricted, it is possible to suppress the load from acting on the terminal due to the movement of the electric wire member.

[0033] [3] Preferably, the restricting portion includes a restricting portion body that opens and closes the opening, and a hinge that connects one of the two side walls to the restricting portion body.

[0034] According to this structure, the opening of the protector body can be opened and closed by rotating the restriction part body via the hinge. Therefore, the restriction part can be embodied with a simple structure.

[0035] [4] Preferably, the restriction portion body has an engaging portion that engages with the other of the two side walls.

[0036] According to this configuration, the restriction portion body is engaged with the other of the two side walls, so that the restriction portion body can easily maintain the state of closing the opening of the protector body. Therefore, the movement of the electric wire member in the protruding direction of the bolt can be effectively restricted.

[0037] [5] Preferably, when the hinge is set as the first hinge, the limiting portion body comprises: a first part, which is connected to the first hinge and covers the wire member from the side opposite to the bottom wall; a second part, which overlaps with the outer surface of the first part and covers a portion of the wire member that is closer to the terminal in the longitudinal direction than the portion covered by the first part; and a second hinge, which is arranged at an end edge of the first part on the side opposite to the terminal in the longitudinal direction, and connects the first part to the second part, and the second part is arranged to be able to rotate to a position overlapping with the outer surface of the first part and a position unfolded relative to the first part and extending to the side opposite to the terminal in the longitudinal direction via the second hinge.

[0038] For example, when there is a portion protruding from the protector body on the outer peripheral side of the side wall where the first hinge is provided, the restricting portion body may interfere with the portion by rotating the restricting portion body toward the outer peripheral side of the side wall.

[0039] In this regard, according to the above structure, the second part, which is longer than the first part in the above-mentioned length direction, is connected to the first part via the second hinge and overlaps with the outer surface of the first part. In addition, the second part is arranged to be able to rotate to a position overlapping with the outer surface of the first part and a position unfolded relative to the first part via the second hinge. Therefore, when the limiting part body is rotated toward the outer peripheral side of the side wall, the limiting part body can be rotated toward the outer peripheral side of the side wall in a state where the second part is unfolded relative to the first part. At this time, the second part is changed to a state extending from the first part to the side opposite to the terminal in the above-mentioned length direction. That is, the second part is changed to a state extending in a direction away from the above-mentioned part. Therefore, the above-mentioned inconvenience is easily avoided.

[0040] [6] Preferably, the restricting portion and the protector body are formed integrally.

[0041] According to this configuration, it is possible to suppress an increase in the number of components of the protector and, further, the number of components in the wire harness.

[0042] [7] Preferably, the electric wire member includes a corrugated tube covering the outer periphery of the electric wire, and the restricting portion restricts movement of the corrugated tube relative to the protector body by contacting the corrugated tube.

[0043] According to this structure, the movement of the electric wire member relative to the protector body is restricted by the corrugated tube. Therefore, it is possible to suppress the terminal from coming off the bolt.

[0044] [8] Preferably, the bellows has a corrugated structure, wherein an annular convex portion and an annular concave portion having an outer diameter smaller than that of the convex portion are alternately arranged in the length direction, and the limiting portion has an engaging convex portion that engages with the concave portion.

[0045] According to this configuration, the engagement convex portion of the restricting portion engages with the concave portion of the corrugated tube, thereby effectively restricting the movement of the corrugated tube relative to the protector body.

[0046] [9] Preferably, the protector includes a cover that is detachably provided on the protector body and covers both the restricting portion and the terminal.

[0047] According to this configuration, the restricting portion and the terminal are covered together by the cover, so that the connection portion of the terminal can be protected and the restricting portion can be prevented from falling off from the protector body.

[0048]

[10] Preferably, when the terminal is set as the first terminal, the wire is set as the first wire, and the wire component is set as the first wire component, a second wire component is provided, the second wire component has a second terminal and a second wire connected to the second terminal, and is electrically connected to the first wire component, the second terminal has a through hole, the bolt is inserted into the through hole of the first terminal and the through hole of the second terminal, and a nut for fastening the first terminal and the second terminal is assembled on the bolt.

[0049] According to this configuration, in the provisional assembly state where the bolt is inserted into the through hole of the first terminal and the first terminal and the second terminal are not fastened by the bolt and the nut, it is possible to suppress the first terminal from coming off the bolt.

[0050]

[11] The protector disclosed in the present invention accommodates an electric wire component, wherein the electric wire component has a terminal and an electric wire connected to the terminal, and the terminal has a through hole. The protector comprises: a protector body having a bottom wall extending in the length direction of the electric wire component, two side walls protruding from both side edges of the bottom wall and opposite to each other, and an opening formed by the two side walls and opposite to the bottom wall; a bolt having a top end pointing to the side opposite to the bottom wall, protruding from the bottom wall and inserted into the through hole of the terminal; and a limiting portion covering only a portion of the electric wire component that is closer to the side opposite to the top end side of the terminal than the through hole in the length direction, and limiting the movement of the electric wire component in the protruding direction of the bolt.

[0051] According to this configuration, the movement of the electric wire member in the protruding direction is restricted inside the protector, thereby preventing the terminal from being disengaged from the bolt.

[0052] [Details of the embodiments of the present disclosure]

[0053] The following is a reference to the attached Figure 1 Specific examples of the wiring harness and protector disclosed in the present invention are described. In each of the drawings, for the sake of convenience of explanation, parts of the structure are sometimes enlarged or simplified. In addition, the size ratios of the various parts are sometimes different in the various drawings. In addition, the present disclosure is not limited to these examples, but is shown in the claims, and is intended to include all changes within the meaning and scope equivalent to the claims. "Orthogonal" in this specification includes not only the case of strict orthogonality, but also the case of approximately orthogonality within the range of the effect of the present embodiment.

[0054] (Structure of the wiring harness 10)

[0055] The wire harness 10 electrically connects electrical devices mounted on a vehicle such as a hybrid vehicle or an electric vehicle, for example.

[0056] like Figure 1 and Figure 2 As shown, the wire harness 10 includes a first wire member 20, a second wire member 30, and a protector 40 that accommodates the first wire member 20 and the second wire member 30. The first wire member 20 and the second wire member 30 are electrically connected inside the protector 40. The first wire member 20 and the second wire member 30 are led out from the protector 40 in opposite directions in the longitudinal direction of the first wire member 20, for example.

[0057] Hereinafter, the longitudinal direction of the first electric wire member 20 will be simply referred to as the longitudinal direction.

[0058] (Structure of the First Electric Wire Member 20)

[0059] like Figure 2As shown, the first electric wire member 20 includes a first terminal 21, a first electric wire 22 connected to the first terminal 21, and a corrugated tube 25 covering the outer periphery of the first electric wire 22. The corrugated tube 25 is led out from the protector 40.

[0060] (Structure of the first terminal 21)

[0061] The first terminal 21 has a circular through hole 21 a. As a material of the first terminal 21 , for example, a metal material such as copper, copper alloy, aluminum, aluminum alloy, stainless steel, etc. can be used.

[0062] (Structure of the First Electric Wire 22)

[0063] The first electric wire 22 includes a core wire 23 made of a conductor and an insulating coating 24 covering the outer periphery of the core wire 23. As the material of the core wire 23, for example, a metal material such as copper or aluminum can be used. As the material of the insulating coating 24, for example, a synthetic resin containing a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene as a main component can be used.

[0064] The core wire 23 is exposed from the insulating coating 24 at the end of the first electric wire 22. The core wire 23 exposed from the insulating coating 24 is electrically connected to the first terminal 21.

[0065] (Structure of bellows 25)

[0066] The bellows 25 has a bellows structure in which annular convex portions 26 and annular concave portions 27 having an outer diameter smaller than that of the convex portions 26 are alternately provided in the longitudinal direction. The bellows 25 has flexibility.

[0067] For example, a resin material having conductivity or a resin material having no conductivity can be used as the material of the corrugated tube 25. For example, a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin can be used as the resin material.

[0068] The end of the corrugated tube 25 drawn out from the protector 40 and the first electric wire 22 are fixed by a fixing member 28 such as a band. The fixing member 28 is wrapped around the end of the corrugated tube 25 and the entire circumference of the first electric wire 22. Thus, the relative movement of the corrugated tube 25 and the first electric wire 22 can be restricted.

[0069] (Structure of the Second Electric Wire Member 30)

[0070] The second electric wire member 30 includes a second terminal 31 and a second electric wire 32 connected to the second terminal 31 .

[0071] The second terminal 31 and the second electric wire 32 have the same structure as the first terminal 21 and the first electric wire 22. Therefore, regarding the structure of the second electric wire member 30, the reference numeral "3*" which is obtained by adding "10" to the reference numeral "2*" indicating the structure of the first electric wire member 20 is marked to omit repeated description.

[0072] (Structure of Protector 40)

[0073] like Figure 1 As shown, the protector 40 includes a protector body 50 , a bolt 70 protruding from the protector body 50 , a restricting portion 80 provided integrally with the protector body 50 , and a cover 90 detachably provided on the protector body 50 .

[0074] (Structure of Protector Main Body 50)

[0075] like Figure 3 and Figure 4 As shown, the protector body 50 includes a bottom wall 51 extending in the longitudinal direction, two side walls 52 protruding from both side edges of the bottom wall 51 and facing each other, and an opening 53 facing the bottom wall 51. The opening 53 is formed by the two side walls 52. As a material of the protector body 50, for example, an insulating material such as synthetic resin can be used.

[0076] In the following description, one of the two side walls 52 may be distinguished as a side wall 52A, and the other of the two side walls 52 may be distinguished as a side wall 52B.

[0077] The protector body 50 has a first end 50A located at one end in the longitudinal direction and a second end 50B located at the other end in the longitudinal direction. The first electric wire member 20 is led out from the first end 50A. The second electric wire member 30 is led out from the second end 50B.

[0078] The portions of the two side walls 52 that constitute the first end 50A have protruding ends 52 a that protrude from the other portions of the side walls 52 .

[0079] The first end 50A has a plurality of engagement projections 54 disposed on the inner surface thereof to engage with the recess 27 of the bellows 25. The plurality of engagement projections 54 are disposed at intervals in the longitudinal direction. Each engagement projection 54 is formed in an arc shape along the outer peripheral surface of the recess 27, for example.

[0080] The plurality of engagement protrusions 54 include an engagement protrusion 54A extending from the bottom wall 51 to the protrusion 52a of the side wall 52. The plurality of engagement protrusions 54 include, for example, two engagement protrusions 54A. The engagement protrusion 54A is formed in, for example, a U shape. For example, two engagement protrusions 54 are provided on the two engagement protrusions 54A.

[0081] like Figure 3 and Figure 5As shown, a portion of the side wall 52B constituting the first end 50A is provided with a disengagement prevention protrusion 55, and the disengagement prevention protrusion 55 prevents the bellows 25 from being disengaged from the opening 53. The disengagement prevention protrusion 55 is provided between the two engaging convex portions 54A. The disengagement prevention protrusion 55 protrudes from the side wall 52B toward the side wall 52A. The bellows 25 accommodated in the protector body 50 contacts the disengagement prevention protrusion 55, thereby preventing the bellows 25 from being disengaged from the opening 53.

[0082] like Figure 3 and Figure 4 As shown, a positioning protrusion 56 with which the end surface of the bellows 25 contacts is provided in the portion between the first end 50A and the second end 50B of the protector body 50. The positioning protrusion 56 protrudes from the bottom wall 51 and is connected to the two side walls 52.

[0083] The protector body 50 includes a plurality of first engagement frame portions 57 that fix the restriction portion 80 to the protector body 50. The protector body 50 includes, for example, three first engagement frame portions 57.

[0084] One first engagement frame portion 57 is provided at a portion of the side wall 52B facing a first hinge 82 of a restricting portion 80 described later. The remaining two first engagement frame portions 57 are provided at portions of the two side walls 52 facing each other with the positioning protrusion 56 interposed therebetween.

[0085] The protector body 50 has a plurality of second engagement frame portions 58 for fixing the cover 90 to the protector body 50. The protector body 50 has four second engagement frame portions 58, for example.

[0086] The two second engagement frame portions 58 are provided at the portions of the two side walls 52B that constitute the first end 50A. The remaining two second engagement frame portions 58 are provided at the portions of the two side walls 52 that constitute the second end 50B.

[0087] like Figure 2 As shown, a fixing portion 60 that protrudes from the bottom wall 51 and fixes the bolt 70 is provided in the portion between the positioning protrusion 56 and the second end 50B in the protector body 50. The fixing portion 60 is provided integrally with the bottom wall 51. The fixing portion 60 has a through hole 61 that penetrates the protector body 50 in a direction orthogonal to the bottom wall 51.

[0088] Two engaging pieces 62 extending in the axial direction of the through hole 61 and facing each other are provided inside the through hole 61. The two engaging pieces 62 are cantilevered with one end connected to the bottom wall 51. The two engaging pieces 62 are provided to be elastically deformable in a direction away from each other.

[0089] (Structure of bolt 70)

[0090] The bolt 70 is inserted into the through hole 21a of the first terminal 21 and the through hole 31a of the second terminal 31. The bolt 70 has a head 71 received in the through hole 61 of the fixing portion 60, a male thread portion 72 protruding from the head 71 toward the opening 53, and a top end 73 extending from the male thread portion 72. The protruding direction of the bolt 70 is orthogonal to the bottom wall 51. The bolt 70 protrudes in the above-mentioned protruding direction to a position farther from the bottom wall 51 than the side wall 52.

[0091] The head portion 71 is formed in, for example, a quadrangular column shape, and a portion of the head portion 71 on the opposite side to the bottom wall 51 engages with the inner wall of the fixing portion 60 in the protruding direction.

[0092] The top end 73 is directed to the side opposite to the bottom wall 51. The top end 73 is exposed from the protector body 50.

[0093] The nut 100 is mounted on the male thread portion 72 . The first terminal 21 and the second terminal 31 are fastened together by the bolt 70 and the nut 100 .

[0094] The bolt 70 is inserted into the through hole 61 of the fixing portion 60 in the direction from the bottom wall 51 toward the opening 53. When the bolt 70 is inserted into the through hole 61, the head 71 moves while contacting the engaging pieces 62, so that the two engaging pieces 62 are elastically deformed in a direction away from each other. When the head 71 moves in the above-mentioned protruding direction to contact the inner wall of the fixing portion 60, the two engaging pieces 62 elastically recover and engage with the head 71. Thus, the bolt 70 is fixed to the fixing portion 60.

[0095] (Structure of the Limiting Section 80)

[0096] like Figure 1 As shown in FIG. 5 , the restricting portion 80 covers a portion of the opening 53 of the protector body 50. The restricting portion 80 covers only a portion of the first wire member 20 that is closer to the side opposite to the tip side of the first terminal 21 than the through hole 21a of the first terminal 21 in the length direction, and restricts the movement of the first wire member 20 in the protruding direction of the bolt 70. The restricting portion 80 covers the first wire 22 and the corrugated tube 25 in the first wire member 20. The restricting portion 80 contacts the corrugated tube 25, thereby restricting the movement of the corrugated tube 25 relative to the protector body 50.

[0097] As a material of the restriction portion 80, an insulating material such as synthetic resin can be used, for example. The restriction portion 80 is formed integrally with the protector body 50. More specifically, the restriction portion 80 and the protector body 50 are formed integrally with a single resin material.

[0098] like Figure 3 and Figure 4As shown, the restriction portion 80 includes a restriction portion main body 81 that opens and closes the opening 53 , and a first hinge 82 that connects the side wall 52A and the restriction portion main body 81 .

[0099] The restricting portion body 81 includes a first portion 83 covering the first electric wire member 20 from the side opposite to the bottom wall 51 , a second portion 88 overlapping the outer surface of the first portion 83 , and a second hinge 87 connecting the first portion 83 and the second portion 88 .

[0100] The first portion 83 includes two arms 84 facing each other and a connecting portion 85 connecting the ends of the two arms 84. The first portion 83 is door-shaped. One of the two arms 84 is connected to the side wall 52A via the first hinge 82. The other of the two arms 84 includes a first engaging claw 81a engaged with the first engaging frame portion 57. The first engaging claw 81a is an example of an engaging portion.

[0101] The first hinge 82 is provided in a portion of the side wall 52A between the first end 50A and the positioning protrusion 56. The first hinge 82 extends in the longitudinal direction. The first hinge 82 is formed in a thin-walled shape that is thinner than the arm portion 84 and the side wall 52A.

[0102] The first portion 83 has an inner surface provided with an engaging projection 86 that engages with the recess 27 of the bellows 25. The engaging projection 86 is provided over the connection portion 85 and the two arm portions 84. The engaging projection 86 is formed in an arc shape along the outer peripheral surface of the recess 27, for example.

[0103] The second hinge 87 is provided at one end edge of the connecting portion 85 on the opposite side from the first terminal 21 in the longitudinal direction. The second hinge 87 extends in the width direction of the protector body 50 perpendicular to the longitudinal direction. The second hinge 87 is formed thinner than the connecting portion 85 and the second portion 88.

[0104] like Figure 1 As shown in FIG. 1 , the second portion 88 is formed to be longer than the first portion 83 in the length direction. When the restriction portion 80 closes the opening 53, the second portion 88 extends to a position closer to the first terminal 21 in the length direction than the first portion 83. That is, the second portion 88 covers a portion of the first electric wire member 20 that is closer to the first terminal 21 in the length direction than the portion covered by the first portion 83. More specifically, the second portion 88 covers the end portion of the corrugated tube 25.

[0105] like Figure 6 As shown, the end portion of the second portion 88 on the opposite side to the second hinge 87 is formed in an arc shape along the outer circumference of the bellows 25. Two first engagement claws 81a that engage with the first engagement frame portion 57 are provided at this end portion.

[0106] The inner surface of the second portion 88 is provided with a plurality of engagement projections 89 that engage with the recess 27 of the bellows 25. The plurality of engagement projections 89 are provided at intervals in the longitudinal direction. Each engagement projection 89 is formed in an arc shape along the outer peripheral surface of the recess 27, for example.

[0107] The second portion 88 is configured to be rotatable about the second hinge 87. More specifically, the second portion 88 is configured to be rotatable via the second hinge 87 to an overlapping position overlapping the outer surface of the first portion 83 and an unfolded position unfolded relative to the first portion 83 and extending to the side opposite to the first terminal 21 in the length direction.

[0108] (Structure of cover 90)

[0109] like Figure 1 As shown, the cover 90 covers the entire opening 53 of the protector body 50. Therefore, the cover 90 covers the restricting portion 80, the first terminal 21, and the second terminal 31. As a material of the cover 90, for example, an insulating material such as synthetic resin can be used.

[0110] like Figure 1 and Figure 5 As shown, the cover 90 includes a top wall 91 extending in the longitudinal direction and facing the bottom wall 51 , and two side walls 92 protruding from both side edges of the top wall 91 and facing each other.

[0111] The cover 90 has four second engagement claws 90 a that engage with the second engagement frame portion 58 . The second engagement claws 90 a are provided on the side wall 92 .

[0112] In a state where the cover 90 is attached to the protector body 50 , a gap is provided between the top wall 91 and the restriction portion 80 .

[0113] (Assembly method of wiring harness 10)

[0114] like Figure 2 and Figure 6 As shown, when the wire harness 10 is assembled, the first electric wire member 20 is first housed in the protector body 50 through the opening 53. At this time, the first terminal 21 is arranged so that the bolt 70 is inserted into the through hole 21a of the first terminal 21. In addition, the end surface of the corrugated tube 25 is brought into contact with the positioning protrusion 56 and the plurality of engaging protrusions 54 are engaged with the recessed portion 27. Thus, the corrugated tube 25 is positioned in the protector body 50 in the longitudinal direction, and thus the length of the corrugated tube 25 drawn out from the protector body 50 is naturally determined.

[0115] Next, the restricting portion 80 at the extended position is rotated about the first hinge 82, and the first engaging claw 81a of the first portion 83 is engaged with the first engaging frame portion 57 of the side wall 52B. At this time, the engaging convex portion 86 of the first portion 83 is engaged with the concave portion 27 of the bellows 25.

[0116] like Figure 2 and Figure 7 As shown, the second part 88 is then rotated around the second hinge 87 until the limiting part 80 becomes the overlapping position, and the first engaging claw 81a of the second part 88 is engaged with the first engaging frame part 57 of the two side walls 52. At this time, the engaging convex part 89 of the second part 88 is engaged with the concave part 27 of the bellows 25.

[0117] As described above, the engaging convex portion 86 of the first portion 83 and the engaging convex portion 89 of the second portion 88 are engaged with the concave portion 27 of the corrugated tube 25. Thus, the movement of the corrugated tube 25 in the length direction is restricted. In addition, since the first electric wire 22 and the corrugated tube 25 are fixed by the fixing member 28, the movement of the entire first electric wire member 20 can be restricted by the restricting portion 80.

[0118] Next, the second electric wire member 30 is housed inside the protector body 50. At this time, the second terminal 31 is arranged so that the bolt 70 is inserted into the through hole 31a. Thus, the first terminal 21 and the second terminal 31 overlap in the protruding direction of the bolt 70.

[0119] Next, the nut 100 is assembled to the male thread portion 72 of the bolt 70, thereby fastening the first terminal 21 and the second terminal 31. Thus, the first terminal 21 and the second terminal 31 are electrically connected. In addition, since the bolt 70 is not covered by the restriction portion 80, the assembly operation of the nut 100 to the bolt 70 can be easily performed.

[0120] Finally, the cover 90 is attached to the protector body 50 by engaging the second engagement claws 90 a of the cover 90 with the second engagement frame portion 58 of the protector body 50 .

[0121] In this way, the wire harness 10 is assembled.

[0122] The function and effect of this embodiment will be described.

[0123] (1) The wire harness 10 includes: a first wire member 20 having a first terminal 21 and a first wire 22; and a protector 40 for accommodating the first wire member 20. The protector 40 includes a protector body 50, a bolt 70, and a restricting portion 80. The protector body 50 includes a bottom wall 51 extending in the longitudinal direction, two side walls 52 protruding from both side edges of the bottom wall 51 and facing each other, and an opening 53 formed by the two side walls 52 and facing the bottom wall 51. The bolt 70 has a top end 73 pointing to the side opposite to the bottom wall 51, protruding from the protector body 50 and inserted into the through hole 21a of the first terminal 21. The restricting portion 80 covers only a portion of the first wire member 20 that is closer to the side opposite to the top end side of the first terminal 21 than the through hole 21a in the longitudinal direction, and restricts the movement of the first wire member 20 in the protruding direction of the bolt 70.

[0124] According to such a configuration, the movement of the first electric wire member 20 in the protruding direction is restricted inside the protector 40 . Therefore, it is possible to suppress the first terminal 21 from coming off the bolt 70 .

[0125] In addition, according to the above structure, Figure 8 As shown, in the provisional assembly state where the bolt 70 is inserted only into the through hole 21a of the first terminal 21, the first terminal 21 can be prevented from being detached from the bolt 70. Therefore, the wire harness 10 in the provisional assembly state can be easily transported.

[0126] (2) The restriction portion 80 restricts movement of the first electric wire member 20 in the longitudinal direction by coming into contact with the first electric wire member 20 .

[0127] According to such a configuration, since the movement of the first electric wire member 20 in the longitudinal direction is restricted, it is possible to suppress the load from acting on the first terminal 21 due to the movement of the first electric wire member 20 .

[0128] (3) The restriction portion 80 includes the restriction portion main body 81 that opens and closes the opening 53 of the protector main body 50 , and the first hinge 82 that connects the side wall 52A and the restriction portion main body 81 .

[0129] According to such a structure, the opening 53 of the protector body 50 can be opened and closed by rotating the restriction portion main body 81 via the first hinge 82. Therefore, the restriction portion 80 can be embodied with a simple structure.

[0130] (4) The restriction portion main body 81 includes the first engagement claw 81 a that engages with the side wall 52B.

[0131] According to such a configuration, by engaging restriction portion body 81 with side wall 52B, restriction portion body 81 can easily maintain a state of closing opening 53 of protector body 50 . Therefore, movement of first wire member 20 in the protruding direction of bolt 70 can be effectively restricted.

[0132] (5) The restricting portion body 81 includes: a first portion 83 covering the first electric wire member 20 from the side opposite to the bottom wall 51; a second portion 88 overlapping the outer surface of the first portion 83 and covering a portion of the first electric wire member 20 closer to the first terminal 21 in the length direction than the portion covered by the first portion 83; and a second hinge 87 connecting the first portion 83 and the second portion 88. The second portion 88 is provided so as to be rotatable via the second hinge 87 to a position overlapping the outer surface of the first portion 83 and a position extending relative to the first portion 83 and on the side opposite to the first terminal 21 in the length direction.

[0133] For example, when there is a portion protruding from the protector body 50 on the outer peripheral side of the side wall 52A, the restricting portion body 81 may interfere with the portion by rotating the restricting portion body 81 toward the outer peripheral side of the side wall 52A.

[0134] In this regard, according to the above structure, the second part 88, which is longer than the first part 83 in the above-mentioned length direction, is connected to the first part 83 via the second hinge 87, and overlaps with the outer surface of the first part 83. In addition, the second part 88 is arranged to be able to rotate to a position overlapping with the outer surface of the first part 83 and a position unfolded relative to the first part 83 through the second hinge 87. Therefore, when the limiting part body 81 is rotated toward the outer peripheral side of the side wall 52A, the limiting part body 81 can be rotated toward the outer peripheral side of the side wall 52A in a state where the second part 88 is unfolded relative to the first part 83. At this time, the second part 88 is changed to a state extending from the first part 83 to the side opposite to the first terminal 21 in the above-mentioned length direction. That is, the second part 88 is changed to a state extending in a direction away from the above-mentioned part. Therefore, it is easy to avoid the above-mentioned inconvenience.

[0135] (6) The restricting portion 80 and the protector body 50 are formed integrally.

[0136] According to such a configuration, it is possible to suppress an increase in the number of components of the protector 40 , and further, the number of components in the wire harness 10 .

[0137] (7) The first electric wire member 20 includes the corrugated tube 25 covering the outer periphery of the first electric wire 22. The restricting portion 80 restricts movement of the corrugated tube 25 relative to the protector body 50 by contacting the corrugated tube 25.

[0138] According to such a configuration, the movement of the first electric wire member 20 relative to the protector body 50 is restricted by the bellows 25 . Therefore, it is possible to suppress the first terminal 21 from coming off the bolt 70 .

[0139] (8) The bellows 25 has a bellows structure in which the annular convex portion 26 and the annular concave portion 27 having an outer diameter smaller than that of the convex portion 26 are alternately provided in the longitudinal direction. The restricting portion 80 has the engaging convex portions 86 and 89 that engage with the concave portion 27 .

[0140] According to such a configuration, the engagement projections 86 and 89 of the restriction portion 80 engage with the recessed portion 27 of the bellows 25 , thereby effectively restricting the movement of the bellows 25 relative to the protector body 50 .

[0141] (9) The protector 40 includes the cover 90 , which is detachably provided on the protector body 50 and covers both the restricting portion 80 and the first terminal 21 .

[0142] According to such a configuration, the restricting portion 80 and the first terminal 21 are covered together by the cover 90 , so that the connection portion between the first terminal 21 and the second terminal 31 can be protected and the restricting portion 80 can be prevented from falling off from the protector body 50 .

[0143] (10) The wiring harness 10 includes the second terminal 31 and the second electric wire 32, and is provided with the second electric wire member 30 electrically connected to the first electric wire member 20. The bolt 70 is inserted into the through hole 21a of the first terminal 21 and the through hole 31a of the second terminal 31. The nut 100 for fastening the first terminal 21 and the second terminal 31 is mounted on the bolt 70.

[0144] With such a configuration, in a temporary assembly state where the bolt 70 is inserted into the through hole 21 a of the first terminal 21 and the first terminal 21 and the second terminal 31 are not fastened by the bolt 70 and the nut 100 , the first terminal 21 can be prevented from coming off the bolt 70 .

[0145] (11) The protector 40 includes a protector body 50, a bolt 70, and a restricting portion 80. The protector body 50 includes a bottom wall 51 extending in the longitudinal direction, two side walls 52 protruding from both side edges of the bottom wall 51 and facing each other, and an opening 53 formed by the two side walls 52 and facing the bottom wall 51. The bolt 70 has a top end 73 pointing to the side opposite to the bottom wall 51, protrudes from the protector body 50, and is inserted into the through hole 21a of the first terminal 21. The restricting portion 80 covers only a portion of the first electric wire member 20 that is closer to the side opposite to the top end side of the first terminal 21 than the through hole 21a in the longitudinal direction, and restricts the movement of the first electric wire member 20 in the protruding direction of the bolt 70.

[0146] According to such a configuration, the movement of the first electric wire member 20 in the protruding direction is restricted inside the protector 40 . Therefore, it is possible to suppress the first terminal 21 from coming off the bolt 70 .

[0147] <Change example>

[0148] This embodiment can be implemented as follows: This embodiment and the following modifications can be implemented in combination with each other within the scope of no technical contradiction.

[0149] ■The second electric wire member 30 can be omitted from the wire harness 10 .

[0150] ■The cover 90 can be omitted from the protector 40 .

[0151] ■ The restricting portion 80 may include a projection that presses the first electric wire member 20 toward the bottom wall 51 instead of the engaging projections 86 and 89. In this case, the movement of the first electric wire member 20 in the longitudinal direction is restricted by the friction force acting on the first electric wire member 20 due to the pressing force of the projection.

[0152] ■At least one of the engagement projection 86 and the engagement projection 89 can be omitted from the restriction portion 80 . When the engagement projection 89 is omitted from the restriction portion 80 , the second portion 88 may press the bellows 25 toward the bottom wall 51 .

[0153] ■The corrugated tube 25 can be omitted from the first electric wire member 20 . In this case, the restriction portion 80 may be in direct contact with the first electric wire 22 .

[0154] ■The restriction portion 80 may be provided separately from the protector body 50. The restriction portion 80 may include, for example, a first hinge that is separate from the side wall 52A and the restriction portion body 81.

[0159] The restriction portion 80 does not need to be in contact with the first electric wire member 20. Even in this case, the first electric wire member 20 comes into contact with the restriction portion 80 when moving in the protruding direction of the bolt 70, so the movement of the first electric wire member 20 in the protruding direction is restricted.

[0160] The restriction portion 80 may cover a portion of the first terminal 21 that is closer to the side opposite to the tip of the first terminal 21 than the through hole 21a in the length direction. The restriction portion 80 may cover, for example, a connection portion between the first terminal 21 and the core wire 23.

[0161] The bolt 70 may protrude obliquely relative to the bottom wall 51 .

[0162] The bolt 70 may be insert-molded with respect to the protector body 50 .

[0163] ● Fig. 9 and Fig.10 As shown, the protector 140 may also include a cover 190 instead of the cover 90. The cover 190 includes a first cover 290 and a second cover 390 which are divided in the length direction and adjacent to each other. The first cover 290 covers a part of the limiting portion 80. The second cover 390 covers a part adjacent to the above-mentioned part of the limiting portion 80, the first terminal 21, and the second terminal 31. The first cover 290 and the second cover 390 are divided in the length direction at the arc-shaped part forming the second portion 88. The first cover 290, for example, includes two second engaging claws 290a, a total of four, provided on each side wall 292. The second cover 390, for example, includes one second engaging claw 390a, a total of two, provided on each side wall 392. The protector body 150, for example, includes six second engaging frame portions 58, which are respectively engaged with the four second engaging claws 290a and the two second engaging claws 390a. An opposing wall 293 extending toward the second portion 88 is provided at the end of the first cover 290 that is opposed to the second cover 390 in the longitudinal direction. The opposing wall 293 is formed in an arc shape along the outer circumference of the second portion 88. The opposing wall 293 is in contact with the second portion 88. In this modification, the same reference numerals are given to the same structures as those in the above-described embodiment, and for corresponding structures, duplicate descriptions are omitted by adding reference numerals "100" or "200" or "300" to the reference numerals representing the structures in the above-described embodiment.
