Description

[Technical Field]

[0001] The present disclosure relates to a wire harness and a protector. [Background technology]

[0002] Conventionally, there has been known a wire harness including a plurality of electric wire members electrically connected to one another and a protector that houses these electric wire members (see, for example, Patent Document 1). The wire harness described in Patent Document 1 includes a first electric wire member, a second electric wire member, and a third electric wire member. The first electric wire member has a first terminal that is L-shaped. The second electric wire member and the third electric wire member have second terminals and third terminals, respectively.

[0003] The protector has a bottom wall extending in the longitudinal direction of the first wire member, two side walls projecting from both side edges of the bottom wall and facing each other, and an opening facing the bottom wall. The opening is defined by the two side walls.

[0004] Inside the protector, there are two bolts with their heads embedded in the bottom wall. The tips of the two bolts point away from the bottom wall. The protector is equipped with a removable cover that covers the opening.

[0005] The first terminal has two through holes into which two bolts are inserted. The second terminal has a through hole into which one of the bolts is inserted. The third terminal has a through hole into which the other bolt is inserted. One of the bolts is inserted into one of the through holes of the first terminal and the through hole of the second terminal. The other bolt is inserted into the other of the through holes of the first terminal and the through hole of the third terminal. A nut is attached to each of the bolts. As a result, the first terminal is electrically connected to both the second terminal and the third terminal. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-19434 Summary of the Invention [Problem to be solved by the invention]

[0007] When assembling such a wire harness, a terminal of one electric wire member is accommodated inside a protector and a bolt is inserted into the through-hole of the terminal. Then, a terminal of another electric wire member is accommodated inside the same protector and a bolt is inserted into the through-hole of the other electric wire member. Then, a nut is attached to the bolt to electrically connect the electric wire members. In this case, in a pre-assembled state in which only one electric wire member is accommodated inside the protector, there is a risk that the terminal of the electric wire member may come loose from the bolt. This problem occurs not only during the assembly of a wire harness, but also when the wire harness is transported in a pre-assembled state.

DETAILED DESCRIPTION OF THE INVENTION

[0013] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. [1] A wire harness of the present disclosure includes a wire member having a terminal with a through hole and an electric wire connected to the terminal, and a protector that houses the wire member. The protector includes a bottom wall extending in the longitudinal direction of the wire member, two side walls protruding from both side edges of the bottom wall and facing each other, and a protector body having an opening formed by the two side walls and facing the bottom wall, a bolt having a tip facing the opposite side to the bottom wall, protruding from the bottom wall and inserted into the through hole of the terminal, and a regulating portion that covers only a portion of the wire member that is opposite to the tip side of the terminal relative to the through hole in the longitudinal direction, and that regulates movement of the wire member in the protruding direction of the bolt.

[0014] According to this configuration, movement of the wire member in the protruding direction is restricted inside the protector, thereby preventing the terminal from slipping out of the bolt. [2] Preferably, the restricting portion restricts movement of the electric wire member in the length direction by contacting the electric wire member.

[0015] According to this configuration, the movement of the electric wire member in the length direction is restricted, and therefore it is possible to suppress the load acting on the terminal due to the movement of the electric wire member. [3] Preferably, the restriction portion has a restriction portion main body that opens and closes the opening, and a hinge that connects one of the two side walls to the restriction portion main body.

[0016] According to this configuration, the opening of the protector body can be opened and closed by rotating the restricting portion body via the hinge, so that the restricting portion can be realized with a simple configuration.

[0017] [4] It is preferable that the restricting portion main body has an engaging portion that engages with the other of the two side walls. With this configuration, by engaging the restricting portion main body with the other of the two side walls, the restricting portion main body can easily maintain the state in which it closes the opening of the protector main body, thereby effectively restricting movement of the electric wire member in the protruding direction of the bolt.

[0018] [5] When the hinge is a first hinge, the regulating body has a first part connected to the first hinge and covering the wire member from the side opposite the bottom wall, a second part overlapping the outer surface of the first part and covering a part of the wire member closer to the terminal in the longitudinal direction than the part covered by the first part, and a second hinge provided on one end edge of the first part opposite the terminal in the longitudinal direction and connecting the first part and the second part, and it is preferable that the second part is rotatably provided via the second hinge between a position where it is overlapped on the outer surface of the first part and a position where it is expanded relative to the first part and extends on the side opposite the terminal in the longitudinal direction.

[0019] For example, if there is a portion that protrudes from the protector main body on the outer periphery of the side wall where the first hinge is provided, rotating the regulating unit main body toward the outer periphery of the side wall may cause the regulating unit main body to interfere with the portion.

[0020] In this regard, according to the above configuration, the second part, which is longer in the longitudinal direction than the first part, is connected to the first part via a second hinge and overlaps the outer surface of the first part. The second part is rotatably disposed via the second hinge between a position where it overlaps the outer surface of the first part and a position where it is deployed relative to the first part. Therefore, when rotating the restricting body toward the outer periphery of the side wall, the restricting body can be rotated toward the outer periphery of the side wall with the second part deployed relative to the first part. At this time, the second part extends from the first part toward the opposite side of the terminal in the longitudinal direction. That is, the second part extends in a direction away from the part. This makes it easier to avoid the above-mentioned inconvenience.

[0021] [6] It is preferable that the restricting portion and the protector body are integrally formed. According to this configuration, an increase in the number of parts in the protector, and therefore in the number of parts in the wire harness, can be suppressed.

[0022] [7] It is preferable that the electric wire member has a corrugated tube that covers 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.

[0023] According to this configuration, movement of the electric wire member relative to the protector body is restricted via the corrugated tube, thereby preventing the terminal from slipping out of the bolt. [8] It is preferable that the corrugated tube has a bellows structure in which annular convex portions and annular concave portions having an outer diameter smaller than that of the convex portions are alternately arranged in the longitudinal direction, and that the regulating portion has an engaging convex portion that engages with the concave portion.

[0024] According to this configuration, the engaging protrusion of the restricting portion engages with the recess of the corrugated tube, thereby effectively restricting movement of the corrugated tube relative to the protector body. [9] It is preferable that the protector has a cover that is detachably attached to the protector body and covers the restricting portion and the terminals collectively.

[0025] According to this configuration, the restricting portion and the terminal are covered together by the cover, so that the connection points of the terminals can be protected and the restricting portion can be prevented from coming off the protector body.

[0026]

[10] When the terminal is a first terminal, the electric wire is a first electric wire, and the electric wire member is a first electric wire member, it is preferable that the electric wire member has a second terminal having a through hole, and a second electric wire connected to the second terminal and is electrically connected to the first electric wire member, the bolt is inserted into the through hole of the first terminal and the through hole of the second terminal, and a nut is attached to the bolt to fasten the first terminal and the second terminal.

[0027] According to this configuration, in a temporary assembly state in which a 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 nut, it is possible to prevent the first terminal from coming loose from the bolt.

[0028]

[11] The protector of the present disclosure is a protector that houses an electric wire member having a terminal with a through hole and an electric wire connected to the terminal, and includes a bottom wall extending in the longitudinal direction of the electric wire member, two side walls protruding from both side edges of the bottom wall and facing each other, and a protector body having an opening formed by the two side walls and facing the bottom wall, a bolt having a tip facing the opposite side to the bottom wall, protruding from the bottom wall and inserted into the through hole of the terminal, and a regulating portion that covers only the portion of the electric wire member opposite the tip side of the terminal relative to the through hole in the longitudinal direction and regulates movement of the electric wire member in the protruding direction of the bolt.

[0029] According to this configuration, movement of the wire member in the protruding direction is restricted inside the protector, thereby preventing the terminal from slipping out of the bolt. [Details of the embodiments of the present disclosure] Specific examples of the wire harness and protector of the present disclosure will be described below with reference to the drawings. In each drawing, for the sake of convenience, some of the configuration may be exaggerated or simplified. Furthermore, the dimensional ratios of each part may differ from one drawing to another. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims. In this specification, "orthogonal" does not only refer to the case where the wiring harness and protector are strictly orthogonal, but also includes the case where the wiring harness and protector are approximately orthogonal within the scope of the effect of this embodiment.

[0030] (Configuration of wire harness 10) The wire harness 10 electrically connects electrical devices mounted on a vehicle such as a hybrid vehicle or an electric vehicle.

[0031] 1 and 2, the wire harness 10 includes a first electric wire member 20, a second electric wire member 30, and a protector 40 that houses the first electric wire member 20 and the second electric wire member 30. The first electric wire member 20 and the second electric wire member 30 are electrically connected inside the protector 40. The first electric wire member 20 and the second electric wire member 30 are drawn out from the protector 40 in opposite directions to each other in the longitudinal direction of the first electric wire member 20, for example.

[0032] Hereinafter, the length direction of the first wire member 20 will be simply referred to as the length direction. (Configuration of the first wire member 20) 2, the first electric wire member 20 has 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 drawn out from the protector 40.

[0033] (Configuration of first terminal 21) The first terminal 21 has a circular through-hole 21a. The first terminal 21 can be made of a metal material such as copper, a copper alloy, aluminum, an aluminum alloy, or stainless steel.

[0034] (Configuration of the first electric wire 22) The first electric wire 22 has a core wire 23 made of a conductor and an insulating coating 24 that covers the outer periphery of the core wire 23. The core wire 23 can be made of a metal material such as a copper or aluminum material. The insulating coating 24 can be made of a synthetic resin whose main component is a polyolefin resin such as cross-linked polyethylene or cross-linked polypropylene.

[0035] The core wire 23 is exposed from the insulating sheath 24 at the end of the first electric wire 22. The core wire 23 exposed from the insulating sheath 24 is electrically connected to the first terminal 21. (Configuration of Corrugated Tube 25) The corrugated tube 25 has a bellows structure in which annular projections 26 and annular recesses 27 having an outer diameter smaller than that of the projections 26 are alternately provided in the longitudinal direction. The corrugated tube 25 is flexible.

[0036] For example, a conductive resin material or a non-conductive resin material can be used as the material of the corrugated tube 25. For example, the resin material can be a synthetic resin such as polyolefin, polyamide, polyester, or ABS resin.

[0037] The end of the corrugated tube 25 pulled out from the protector 40 and the first electric wire 22 are fixed by a fixing member 28 such as tape. The fixing member 28 is wrapped around the entire circumference of the end of the corrugated tube 25 and the first electric wire 22. This restricts relative movement between the corrugated tube 25 and the first electric wire 22.

[0038] (Configuration of the second wire member 30) The second electric wire member 30 has a second terminal 31 and a second electric wire 32 connected to the second terminal 31 .

[0039] The second terminal 31 and the second wire 32 have the same configuration as the first terminal 21 and the first wire 22, respectively. Therefore, the configuration of the second wire member 30 is denoted by the symbol "3*", which is obtained by adding "10" to the symbol "2*" indicating the configuration of the first wire member 20, and redundant explanations will be omitted.

[0040] (Configuration of protector 40) As shown in FIG. 1, the protector 40 comprises a protector body 50, a bolt 70 protruding from the protector body 50, a restricting portion 80 formed integrally with the protector body 50, and a cover 90 detachably attached to the protector body 50.

[0041] (Configuration of protector body 50) 3 and 4, the protector body 50 has a bottom wall 51 extending in the length direction, two side walls 52 projecting 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. The protector body 50 can be made of an insulating material such as a synthetic resin, for example.

[0042] In the following description, one of the two side walls 52 may be referred to as a side wall 52A, and the other of the two side walls 52 may be referred to as a side wall 52B. 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 drawn out from the first end 50A. The second electric wire member 30 is drawn out from the second end 50B.

[0043] The portions of the two side walls 52 that form the first end 50A have a tip 52a that protrudes further than the other portions of the side walls 52. The inner surface of the first end 50A is provided with a plurality of engaging protrusions 54 that engage with the recesses 27 of the corrugated tube 25. The engaging protrusions 54 are spaced apart from one another in the longitudinal direction. Each of the engaging protrusions 54 has, for example, an arc shape that follows the outer circumferential surface of the recess 27.

[0044] The plurality of engaging protrusions 54 includes an engaging protrusion 54A extending from the bottom wall 51 to the protruding end 52a of the side wall 52. The plurality of engaging protrusions 54 includes, for example, two engaging protrusions 54A. The engaging protrusion 54A has, for example, a U-shape. Two more engaging protrusions 54 are provided between the two engaging protrusions 54A.

[0045] 3 and 5, a retaining projection 55 that prevents the corrugated tube 25 from slipping out of the opening 53 is provided on the portion of the side wall 52B that constitutes the first end 50A. The retaining projection 55 is provided between the two engaging protrusions 54A. The retaining projection 55 protrudes from the side wall 52B toward the side wall 52A. The corrugated tube 25 housed inside the protector body 50 comes into contact with the retaining projection 55, thereby preventing the corrugated tube 25 from slipping out of the opening 53.

[0046] 3 and 4, a positioning protrusion 56 that comes into contact with the end face of the corrugated tube 25 is provided in a portion of the protector body 50 between the first end 50A and the second end 50B. The positioning protrusion 56 protrudes from the bottom wall 51 and is connected to the two side walls 52.

[0047] The protector body 50 has a plurality of first engagement frames 57 that fix the restriction portion 80 to the protector body 50. The protector body 50 has, for example, three first engagement frames 57.

[0048] One first engagement frame 57 is provided on a portion of the side wall 52B facing a first hinge 82 of a restriction portion 80 (described later). The remaining two first engagement frames 57 are provided on portions of the two side walls 52 facing each other with the positioning protrusion 56 in between.

[0049] The protector body 50 has a plurality of second engagement frames 58 that fix the cover 90 to the protector body 50. The protector body 50 has, for example, four second engagement frames 58.

[0050] The two second engagement frames 58 are provided on the two side walls 52B at portions that form the first ends 50A, and the remaining two second engagement frames 58 are provided on the two side walls 52 at portions that form the second ends 50B.

[0051] 2, a fixing portion 60 that protrudes from the bottom wall 51 and fixes the bolt 70 is provided in a portion of the protector body 50 between the positioning projection 56 and the second end 50B. 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 perpendicular to the bottom wall 51.

[0052] Two engaging pieces 62 that extend in the axial direction of the through hole 61 and face 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 so as to be elastically deformable in directions away from each other.

[0053] (Bolt 70 configuration) 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 housed inside the through hole 61 of the fixing part 60, a male threaded part 72 protruding from the head 71 toward the opening 53, and a tip 73 extending from the male threaded part 72. The protruding direction of the bolt 70 is perpendicular to the bottom wall 51. The bolt 70 protrudes in the protruding direction to a position farther from the bottom wall 51 than the side wall 52.

[0054] The head 71 has, for example, a quadrangular prism shape. The portion of the head 71 opposite to the bottom wall 51 engages with the inner wall of the fixing part 60 in the protruding direction. The tip 73 faces away from the bottom wall 51. The tip 73 is exposed from the protector body 50.

[0055] A nut 100 is attached to 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. The bolt 70 is inserted into the through-hole 61 of the fixing part 60 in a 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 engagement pieces 62, causing the two engagement pieces 62 to elastically deform in directions away from each other. When the head 71 moves in the protruding direction until it contacts the inner wall of the fixing part 60, the two engagement pieces 62 elastically return to their original position and engage with the head 71. This fixes the bolt 70 to the fixing part 60.

[0056] (Configuration of the restriction portion 80) 1 , 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 electric wire member 20 that is on the opposite side of the tip of the first terminal 21 from the through hole 21a of the first terminal 21 in the longitudinal direction, and restricts movement of the first electric wire member 20 in the protruding direction of the bolt 70. The restricting portion 80 covers the first electric wire 22 and the corrugated tube 25 of the first electric wire member 20. The restricting portion 80 restricts movement of the corrugated tube 25 relative to the protector body 50 by coming into contact with the corrugated tube 25.

[0057] The restricting portion 80 may be made of an insulating material such as synthetic resin. The restricting portion 80 is integrally formed with the protector body 50. More specifically, the restricting portion 80 and the protector body 50 are integrally formed from a single resin material.

[0058] As shown in FIGS. 3 and 4, the restricting portion 80 has a restricting portion main body 81 that opens and closes the opening 53, and a first hinge 82 that connects the side wall 52A and the restricting portion main body 81. The restricting portion main body 81 has a first part 83 that covers the first electric wire member 20 from the side opposite the bottom wall 51, a second part 88 that is superimposed on the outer surface of the first part 83, and a second hinge 87 that connects the first part 83 and the second part 88.

[0059] The first portion 83 has two arms 84 facing each other and a connecting portion 85 connecting the ends of the two arms 84. The first portion 83 is gate-shaped. One of the two arms 84 is connected to the side wall 52A via a first hinge 82. The other of the two arms 84 has a first engagement claw 81a that engages with the first engagement frame 57. The first engagement claw 81a is an example of an engagement portion.

[0060] 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 to be thinner than the arm portion 84 and the side wall 52A.

[0061] An engaging protrusion 86 that engages with the recess 27 of the corrugated tube 25 is provided on the inner surface of the first portion 83. The engaging protrusion 86 is provided across the connecting portion 85 and the two arm portions 84. The engaging protrusion 86 has, for example, an arc shape that follows the outer peripheral surface of the recess 27.

[0062] The second hinge 87 is provided on one end edge of the connecting portion 85 in the longitudinal direction opposite to the first terminal 21. The second hinge 87 extends in the width direction of the protector body 50, which is perpendicular to the longitudinal direction. The second hinge 87 is formed to be thinner than the connecting portion 85 and the second portion 88.

[0063] 1 , the second portion 88 has an elongated shape that is longer in the longitudinal direction than the first portion 83. When the restricting portion 80 closes the opening 53, the second portion 88 extends in the longitudinal direction to a position closer to the first terminal 21 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 longitudinal direction than the portion covered by the first portion 83. More specifically, the second portion 88 covers an end of the corrugated tube 25.

[0064] 6, the end of the second portion 88 opposite the second hinge 87 is arc-shaped along the outer periphery of the corrugated tube 25. Two first engagement claws 81a that engage with the first engagement frame portion 57 are provided on this end.

[0065] The inner surface of the second portion 88 is provided with a plurality of engaging protrusions 89 that engage with the recesses 27 of the corrugated tube 25. The engaging protrusions 89 are spaced apart from one another in the longitudinal direction. Each of the engaging protrusions 89 has, for example, an arc shape that follows the outer circumferential surface of the recess 27.

[0066] The second part 88 is provided rotatably around the second hinge 87. More specifically, the second part 88 is provided rotatably via the second hinge 87 between an overlapping position where it is overlapped on the outer surface of the first part 83 and an expanded position where it is expanded relative to the first part 83 and extends on the opposite side from the first terminal 21 in the longitudinal direction.

[0067] (Cover 90 configuration) 1, the cover 90 covers the entire opening 53 of the protector body 50. Therefore, the cover 90 collectively covers the restricting portion 80, the first terminal 21, and the second terminal 31. The cover 90 may be made of an insulating material such as a synthetic resin.

[0068] As shown in FIGS. 1 and 5, the cover 90 has a top wall 91 that extends in the length direction and faces the bottom wall 51, and two side walls 92 that protrude from both side edges of the top wall 91 and face each other.

[0069] The cover 90 has four second engagement claws 90a that engage with the second engagement frame 58. The second engagement claws 90a are provided on the side wall 92. When the cover 90 is attached to the protector body 50, a gap is provided between the top wall 91 and the restricting portion 80.

[0070] (Assembly mode of wire harness 10) 2 and 6, when assembling the wire harness 10, first, the first electric wire member 20 is accommodated inside the protector body 50 through the opening 53. At this time, the first terminal 21 is positioned so that the bolt 70 is inserted into the through hole 21a of the first terminal 21. Then, the end face of the corrugated tube 25 is brought into contact with the positioning protrusion 56, and the multiple engaging protrusions 54 are engaged with the recesses 27. As a result, the corrugated tube 25 is positioned relative to the protector body 50 in the longitudinal direction, and the length of the corrugated tube 25 to be pulled out from the protector body 50 is automatically determined.

[0071] Next, the restricting portion 80 in the deployed position is rotated around 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 protrusion 86 of the first portion 83 is engaged with the recess 27 of the corrugated tube 25.

[0072] 2 and 7, next, the second part 88 is rotated about the second hinge 87 until the restricting portion 80 reaches the overlapping position, and the first engaging claws 81a of the second part 88 are engaged with the first engaging frame portions 57 of the two side walls 52. At this time, the engaging protrusions 89 of the second part 88 are engaged with the recesses 27 of the corrugated tube 25.

[0073] As a result of the above, the engaging protrusion 86 of the first portion 83 and the engaging protrusion 89 of the second portion 88 are engaged with the recess 27 of the corrugated tube 25. This restricts movement of the corrugated tube 25 in the longitudinal direction. Note that, since the first electric wire 22 and the corrugated tube 25 are fixed by the fixing member 28, movement of the entire first electric wire member 20 is restricted by the restricting portion 80.

[0074] Next, the second wire member 30 is housed inside the protector body 50. At this time, the second terminal 31 is positioned so that the bolt 70 is inserted into the through hole 31a. As a result, the first terminal 21 and the second terminal 31 are overlapped in the protruding direction of the bolt 70.

[0075] Next, the nut 100 is attached to the male thread portion 72 of the bolt 70, thereby fastening the first terminal 21 and the second terminal 31. This electrically connects the first terminal 21 and the second terminal 31. Note that, because the bolt 70 is not covered by the restricting portion 80, the work of attaching the nut 100 to the bolt 70 can be easily performed.

[0076] Finally, the second engagement claws 90 a of the cover 90 are engaged with the second engagement frame portions 58 of the protector body 50 , thereby attaching the cover 90 to the protector body 50 . In this manner, the wire harness 10 is assembled.

[0077] The operation and effects of this embodiment will be described. (1) The wire harness 10 includes a first electric wire member 20 having a first terminal 21 and a first electric wire 22, and a protector 40 that houses the first electric 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 that protrude from both side edges of the bottom wall 51 and face each other, and an opening 53 that is formed by the two side walls 52 and faces the bottom wall 51. The bolt 70 has a tip 73 that faces away from 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 opposite the tip side of the first terminal 21 relative to the through hole 21a in the longitudinal direction, and restricts movement of the first electric wire member 20 in the protruding direction of the bolt 70.

[0078] According to this configuration, movement of the first wire member 20 in the protruding direction is restricted inside the protector 40. Therefore, slipping out of the first terminal 21 from the bolt 70 can be suppressed.

[0079] 8, in a provisionally assembled state in which the bolt 70 is inserted only into the through-hole 21a of the first terminal 21, the above-described configuration can prevent the first terminal 21 from slipping out of the bolt 70. Therefore, the provisionally assembled wire harness 10 can be easily transported.

[0080] (2) The restricting portion 80 restricts the movement of the first electric wire member 20 in the length direction by coming into contact with the first electric wire member 20. According to this configuration, the movement of the first electric wire member 20 in the length direction is restricted, and therefore, the load acting on the first terminal 21 due to the movement of the first electric wire member 20 can be suppressed.

[0081] (3) The restricting portion 80 has a restricting portion main body 81 that opens and closes the opening 53 of the protector main body 50, and a first hinge 82 that connects the side wall 52A and the restricting portion main body 81. According to this configuration, the opening 53 of the protector body 50 can be opened and closed by rotating the restricting portion body 81 via the first hinge 82. Therefore, the restricting portion 80 can be realized with a simple configuration.

[0082] (4) The restricting portion main body 81 has the first engaging claw 81a that engages with the side wall 52B. According to this configuration, by engaging the restricting portion main body 81 with the side wall 52B, the restricting portion main body 81 is more likely to maintain a state in which it closes the opening 53 of the protector main body 50. Therefore, movement of the first electric wire member 20 in the protruding direction of the bolt 70 can be effectively restricted.

[0083] (5) The restricting portion main body 81 has a first portion 83 that covers the first electric wire member 20 from the side opposite to the bottom wall 51, a second portion 88 that is superimposed on the outer surface of the first portion 83 and covers a portion of the first electric wire member 20 that is closer to the first terminal 21 in the longitudinal direction than the portion covered by the first portion 83, and a second hinge 87 that connects the first portion 83 and the second portion 88. The second portion 88 is rotatable via the second hinge 87 between a position where it is superimposed on the outer surface of the first portion 83 and a position where it is unfolded relative to the first portion 83 and extends on the side opposite to the first terminal 21 in the longitudinal direction.

[0084] For example, if there is a portion on the outer periphery of the side wall 52A that protrudes from the protector main body 50, rotating the regulating portion main body 81 toward the outer periphery of the side wall 52A may cause the regulating portion main body 81 to interfere with the above-mentioned portion.

[0085] In this regard, according to the above configuration, the second portion 88, which is longer in the longitudinal direction than the first portion 83, is connected to the first portion 83 via the second hinge 87 and overlaps the outer surface of the first portion 83. The second portion 88 is rotatably disposed via the second hinge 87 between a position where it overlaps the outer surface of the first portion 83 and a position where it is deployed relative to the first portion 83. Therefore, when rotating the restricting portion main body 81 toward the outer periphery of the side wall 52A, the restricting portion main body 81 can be rotated toward the outer periphery of the side wall 52A with the second portion 88 deployed relative to the first portion 83. At this time, the second portion 88 extends from the first portion 83 toward the opposite side from the first terminal 21 in the longitudinal direction. That is, the second portion 88 extends in a direction away from the above-mentioned portion. This makes it easier to avoid the above-mentioned inconvenience.

[0086] (6) The restricting portion 80 and the protector body 50 are integrally formed. According to this configuration, an increase in the number of parts of the protector 40, and therefore the number of parts in the wire harness 10, can be suppressed.

[0087] (7) The first electric wire member 20 has the corrugated tube 25 that covers 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 coming into contact with the corrugated tube 25.

[0088] According to this configuration, movement of the first wire member 20 relative to the protector body 50 is restricted via the corrugated tube 25. Therefore, slipping out of the first terminal 21 from the bolt 70 can be suppressed.

[0089] (8) The corrugated tube 25 has a bellows structure in which annular protrusions 26 and annular recesses 27 having an outer diameter smaller than that of the protrusions 26 are alternately arranged in the longitudinal direction. The restricting portion 80 has engaging protrusions 86, 89 that engage with the recesses 27.

[0090] According to this configuration, the engaging projections 86, 89 of the restricting portion 80 engage with the recesses 27 of the corrugated tube 25, thereby effectively restricting movement of the corrugated tube 25 relative to the protector body 50.

[0091] (9) The protector 40 has a cover 90 that is detachably attached to the protector body 50 and covers the restricting portion 80 and the first terminal 21 collectively. With this configuration, the restricting portion 80 and the first terminal 21 are covered together by the cover 90, which protects the connection point between the first terminal 21 and the second terminal 31 and prevents the restricting portion 80 from coming off the protector main body 50.

[0092] (10) The wire harness 10 includes a second electric wire member 30 having a second terminal 31 and a second electric wire 32 and electrically connected to the first electric wire member 20. A bolt 70 is inserted into the through hole 21a of the first terminal 21 and the through hole 31a of the second terminal 31. A nut 100 is attached to the bolt 70 to fasten the first terminal 21 and the second terminal 31 together.

[0093] With this configuration, in a temporary assembly state in which the bolt 70 is inserted into the through hole 21a 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, it is possible to prevent the first terminal 21 from slipping out of the bolt 70.

[0094] (11) The protector 40 has a protector body 50, a bolt 70, and a restricting portion 80. The protector body 50 has 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 tip 73 facing away from 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 opposite the tip side of the first terminal 21 relative to the through hole 21a in the longitudinal direction, and restricts movement of the first electric wire member 20 in the protruding direction of the bolt 70.

[0095] According to this configuration, movement of the first wire member 20 in the protruding direction is restricted inside the protector 40. Therefore, slipping out of the first terminal 21 from the bolt 70 can be suppressed.

[0096] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0097] The second electric wire member 30 can be omitted from the wire harness 10. The cover 90 can be omitted from the protector 40. The restricting portion 80 may have a protrusion that presses the first electric wire member 20 toward the bottom wall 51, instead of the engaging protrusions 86, 89. In this case, the movement of the first electric wire member 20 in the longitudinal direction is restricted by a frictional force acting on the first electric wire member 20 due to the pressing force of the protrusion.

[0098] At least one of the engaging protrusions 86 and 89 may be omitted from the restricting portion 80. When the engaging protrusions 89 are omitted from the restricting portion 80, the second portion 88 may be configured to press the corrugated tube 25 toward the bottom wall 51.

[0099] The corrugated tube 25 may be omitted from the first electric wire member 20. In this case, the restricting portion 80 may be in direct contact with the first electric wire 22. The restricting portion 80 may be provided separately from the protector main body 50. The restricting portion 80 may have, for example, a first hinge that is separate from the side wall 52A and the restricting portion main body 81.

[0100] The second portion 88 may be omitted from the restricting portion main body 81. In other words, the restricting portion main body 81 may be configured with only the first portion 83. The second hinge 87 may be omitted from the restriction portion 80. In this case, the restriction portion main body 81 may be one in which the first portion 83 and the second portion 88 are integrally provided.

[0101] The first hinge 82 may be omitted from the restricting portion 80. In this case, the restricting portion main body 81 may be provided detachably with respect to the protector main body 50. The restricting portion 80 may be a clamp member that is attached to the protector body 50 and clamps the first electric wire member 20, or a band member that is wrapped around the outer periphery of the protector body 50 and covers the first electric wire member 20 from the side opposite the bottom wall 51.

[0102] The restricting portion 80 does not have to be in contact with the first electric wire member 20. Even in this case, when the first electric wire member 20 moves in the protruding direction of the bolt 70, the restricting portion 80 comes into contact with the first electric wire member 20, and therefore, movement of the first electric wire member 20 in the protruding direction is restricted.

[0103] The restricting portion 80 may cover a portion of the first terminal 21 that is on the opposite side of the through hole 21a in the longitudinal direction from the tip side of the first terminal 21. The restricting portion 80 may cover, for example, a connection portion between the first terminal 21 and the core wire 23.

[0104] The bolt 70 may protrude at an angle relative to the bottom wall 51. The bolt 70 may be insert-molded into the protector body 50 . As shown in FIGS. 9 and 10 , the protector 140 may include a cover 190 instead of the cover 90. The cover 190 is divided in the longitudinal direction into a first cover 290 and a second cover 390 that are adjacent to each other. The first cover 290 covers a portion of the restricting portion 80. The second cover 390 collectively covers a portion of the restricting portion 80 adjacent to the portion, the first terminal 21, and the second terminal 31. The first cover 290 and the second cover 390 are divided in the longitudinal direction at the arc-shaped portion of the second portion 88. The first cover 290 has, for example, four second engagement claws 290a, two on each side wall 292. The second cover 390 has, for example, two second engagement claws 390a, one on each side wall 392. The protector main body 150 has, for example, six second engagement frames 58 that engage with four second engagement claws 290a and two second engagement claws 390a, respectively. An opposing wall 293 extending toward the second portion 88 is provided at the end of the first cover 290 facing the second cover 390 in the longitudinal direction. The opposing wall 293 has an arc shape that follows the outer periphery of the second portion 88. The opposing wall 293 is in contact with the second portion 88. In this modified example, the same components as those in the above embodiment are given the same reference numerals, and corresponding components are given reference numerals obtained by adding "100," "200," or "300" to the reference numerals indicating the components of the above embodiment, thereby avoiding redundant explanations.

[0105] Next, the technical ideas that can be understood from the above-described embodiment and modified examples will be described below. The wire harness includes a terminal having a through hole, an electric wire member having an electric wire connected to the terminal, and a protector that houses the electric wire member, and the protector includes a bottom wall extending in the longitudinal direction of the electric wire member, two side walls that protrude from both side edges of the bottom wall and face each other, and a protector body that has an opening that is formed by the two side walls and faces the bottom wall, a bolt that has a tip that faces the opposite side to the bottom wall, protrudes from the bottom wall, and is inserted into the through hole of the terminal, and a restricting portion that covers only a portion of the electric wire member that is opposite to the tip side of the terminal relative to the through hole in the longitudinal direction, and restricts movement of the electric wire member in the protruding direction of the bolt, and the restricting portion includes a restricting portion main body that opens and closes the opening, and a restricting portion that opens and closes the opening and a restricting portion main body that opens and closes the opening. and a hinge connecting one of the side walls of the terminal and the regulating unit main body, and when the hinge is a first hinge, the regulating unit main body has: a first part connected to the first hinge and covering the wire member from the side opposite the bottom wall; a second part overlapping the outer surface of the first part and covering a part of the wire member closer to the terminal in the longitudinal direction than the part covered by the first part; and a second hinge provided on one end edge of the first part opposite the terminal in the longitudinal direction and connecting the first part and the second part, and the second part is rotatably provided via the second hinge between a position where it is overlapped with the outer surface of the first part and a position where it is expanded relative to the first part and extends on the side opposite the terminal in the longitudinal direction.

[0106] For example, if there is a portion that protrudes from the protector main body on the outer periphery of the side wall where the first hinge is provided, rotating the regulating unit main body toward the outer periphery of the side wall may cause the regulating unit main body to interfere with the portion.

[0107] In this regard, according to the above configuration, the second part, which is longer in the longitudinal direction than the first part, is connected to the first part via a second hinge and overlaps the outer surface of the first part. The second part is rotatably disposed via the second hinge between a position where it overlaps the outer surface of the first part and a position where it is deployed relative to the first part. Therefore, when rotating the restricting body toward the outer periphery of the side wall, the restricting body can be rotated toward the outer periphery of the side wall with the second part deployed relative to the first part. At this time, the second part extends from the first part toward the opposite side of the terminal in the longitudinal direction. That is, the second part extends in a direction away from the part. This makes it easier to avoid the above-mentioned inconvenience. [Explanation of symbols]
