Description

【Technical Field】 【0001】 The present invention relates to, for example, an attachment module that wraps a wire harness formed by bundling electric wires and is attached to a predetermined attachment location on a vehicle body, an attachment structure thereof, and a protective member. 【Background Art】 【0002】 Electrical equipment installed in an automobile or the like is connected to another electrical equipment or a power supply device via a wire harness formed by bundling coated electric wires to form an electrical circuit. Such a wire harness is inserted into a protector to regulate the wiring direction and protect it. Further, as an electrical circuit, it may be connected to a terminal block that holds a plurality of bus bars by a bus bar holder, or an electrical connection box such as a junction box or a relay box having a board mounted inside. 【0003】 And attachment modules such as protectors, terminal blocks, or electrical connection boxes are fastened and fixed to a predetermined attachment location on the vehicle body with a fastening member.

Thereby, the fastening force of the fastening member acts on the collar, and the attachment module can be firmly fixed to the attachment location without the attachment fixing portion being damaged by the fastening force of the fastening member. 【0004】 In the above-described attachment module, for example, in order to suppress the influence of electromagnetic noise, an earth wire may be connected to be energizable to a predetermined attachment location on the vehicle body. That is, it is necessary to perform both fixing to the attachment location and fixing for energization, which makes the work for attachment complicated and the workability cannot be improved. 【Prior Art Documents】 【Patent Documents】 【0005】 [Patent Document 1] Japanese Patent Publication No. 2019-190390 [Overview of the project] [Problems that the invention aims to solve] 【0006】 The present invention aims to provide a mounting module, a mounting structure thereof, and a protective member that can be efficiently and securely attached to a mounting location while allowing current to flow through it.

It is characterized by being a mounting module. 【0008】 Furthermore, this invention relates to a mounting module comprising a mounting body for mounting a conductive mounting member and for mounting to a conductive mounting location, and an electric wire connected to the mounting member, wherein a mounting fixing portion provided on the mounting body is fastened and fixed to the mounting location with a bolt, and a protective member is attached to the mounting fixing portion, which is positioned in an insertion opening provided on the mounting fixing portion through which the bolt is inserted, and which protects the mounting fixing portion from the fastening pressure of the fastening bolt, and the protective member is made of a conductive material. The protective member is provided with an insertion direction portion extending in the insertion direction through which the bolt is inserted into the insertion opening, and a wire fixing portion positioned on the opposite side of the mounting location in the mounting fixing portion for fixing the electric wire, and the protective member is configured as a pair and is positioned opposite to each other at a predetermined distance apart so as to sandwich the insertion opening, the insertion opening is a groove opening that extends from the peripheral edge of the mounting fixing portion toward the interior in a plan view and has an open peripheral edge, and the insertion direction portion is formed along the extending direction of the groove opening. The protective member is provided with a contact flange portion located on the side of the mounting location in the mounting fixing portion and electrically abutting the mounting location, and a flange portion located on the opposite side of the insertion direction portion and extending in a direction perpendicular to the insertion direction, and the wire fixing portion is provided on the flange portion. It is characterized by a mounting structure for mounting modules. 【0009】 Furthermore, this invention relates to a mounting module comprising a mounting body for mounting a conductive mounting member and for mounting to a conductive mounting location, and an electric wire connected to the mounting member, wherein the mounting module is provided with a mounting fixing portion for fastening to the mounting location with a bolt, and the mounting fixing portion is provided with an insertion opening for inserting the bolt, and the mounting fixing portion is provided with an insertion opening for inserting the bolt, and the protective member is provided in the mounting fixing portion and is positioned in the insertion opening to protect the mounting fixing portion from the fastening pressure of the bolt, and is made of a conductive material, and is provided with an insertion direction portion that extends in the direction of insertion for inserting the bolt into the insertion opening, and an electric wire fixing portion that is positioned on the opposite side of the mounting location in the mounting fixing portion and fixes the electric wire, wherein the insertion opening is a groove opening that extends inward in a plan view from the peripheral edge of the mounting fixing portion and the peripheral edge is open, and the insertion direction portion is formed along the extending direction of the groove opening, and when positioned in the insertion opening, a pair of protective members are arranged at opposite locations separated by a predetermined distance so as to sandwich the insertion opening. The mounting and fixing portion is provided with a contact flange portion located on the side of the mounting location and electrically abutting the mounting location, and a flange portion located on the opposite side of the insertion direction portion and extending in a direction perpendicular to the insertion direction, wherein the wire fixing portion is provided on the flange portion. It is characterized by the following: 【0010】 Mounting bodies that are equipped with the aforementioned conductive mounting components and attached to a conductive mounting location include protectors that are attached to a grounded vehicle body panel or other mounting location by inserting a wire harness, electrical connection boxes that are mounted with a circuit board to which the wire harness is connected, and terminal blocks that are mounted with a busbar. 【0011】 The wires connected to the aforementioned mounted components include wires electrically connected to mounted components such as busbars, or ground wires that constitute a wire harness. The bolts used to fasten and secure the mounting location include bolts of separate components that are screwed into the mounting location, and stud bolts embedded in the mounting location. 【0012】 This invention allows mounting modules to be efficiently and securely attached to the mounting location while maintaining electrical conductivity. More specifically, the mounting body, which is equipped with a conductive mounting member and attached to a conductive mounting location, has an insertion opening in its mounting fixing portion for inserting a bolt to fasten and secure it to the mounting location. Furthermore, the protective member that protects the mounting fixing portion from the fastening pressure of the bolt has an insertion direction portion that extends in the direction of insertion through the insertion opening for inserting the bolt. As a result, the mounting fixing portion can be protected from the fastening pressure of the bolt, and the mounting module can be securely attached to the mounting location. 【0013】 Furthermore, the protective member, which is attached to the mounting and fixing portion while positioned in the insertion opening through which the bolt is inserted, is made of a conductive material and is provided with a wire fixing portion. In addition, the wire fixing portion of the protective member is positioned on the opposite side of the mounting location on the mounting and fixing portion and fixes the wire connected to the mounted member. 【0014】 When the mounting part is fastened and secured with bolts to the conductive mounting location, the insertion direction portion of the protective member, which is made of a conductive material, comes into contact with the mounting location, allowing the protective member and the mounting location to conduct electricity. As a result, the wire connected to the wire fixing portion of the protective member will conduct electricity with the mounting location. In this way, by fastening and securing the mounting module to the mounting location with bolts, the wire connected to the mounted member and the conductive mounting location can be electrically connected, and the mounting module can be efficiently mounted to the mounting location in an electrically conductive manner. 【0015】 Furthermore, the protective members are arranged in pairs and are positioned opposite each other so as to straddle the insertion opening. eye, Unlike a cylindrical protective member, the protective member can be attached to the mounting and fixing portion without having to be positioned around the entire circumference of the insertion opening. Therefore, compared to a cylindrical protective member, it is less dependent on the shape and size of the insertion opening and can be easily constructed. 【0016】 Furthermore, since the distance between the pair of protective members can be adjusted according to the size of the insertion opening, the pair of protective members can be arranged to accommodate insertion openings of various sizes. 【0017】 Furthermore, the insertion opening extends from the peripheral edge of the mounting and fixing portion toward the interior in a plan view, and is a groove opening with the peripheral edge open, and the insertion direction portion is formed along the extending direction of the groove opening. 【0018】 This allows for fastening and securing with bolts of multiple shaft diameters simply by adjusting the groove width of the groove opening. Furthermore, since the insertion direction portion is formed along the extending direction of the groove opening, fastening and fixing are possible even if the bolt or the nut to which the bolt fastens is misaligned due to tolerances or the like. 【0019】 Also,A flange portion is provided on the opposite side of the insertion direction portion and extends in a direction orthogonal to the insertion direction, and the wire fixing portion is provided on the flange portion. Therefore, Compared with the case where the wire fixing portion is directly provided on the insertion direction portion of the protection member, the wire fixing portion can be stably provided, a plurality of the wire fixing portions can be provided, and a plurality of wires can be connected. 【0020】 Also, compared with the case where only the insertion direction portion of the protection member is directly abutted against the bolt head or nut, by abutting including the flange portion, the contact area with respect to the bolt head or nut increases, and the protection member can more firmly protect the mounting and fixing portion against the fastening pressure of the bolt. 【0021】 Ma Ta, The protection member is provided with a contact flange portion that is disposed on the side of the attachment location of the attachment and fixing portion and is conductively abutted against the attachment location. Therefore, Compared with the case where the insertion direction portion of the protection member is directly abutted against the attachment location, by providing the contact flange portion, the contact area of the protection member with respect to the attachment location increases, and the conductivity can be improved. 【0022】 Also, as an aspect of the present invention, the insertion opening and the insertion direction portion may be formed in an oval shape through which the bolt shaft portion of the bolt can be inserted. According to the present invention, even if the bolt or the nut to which the bolt is fastened is displaced due to a tolerance or the like with respect to the longitudinal direction of the insertion opening and the insertion direction portion formed in an oval shape, fastening and fixing can be performed. 【0023】 Also, as an aspect of the present invention, a plurality of the attachment and fixing portions are provided on the attachment main body, one of the plurality of attachment and fixing portions is used as a reference attachment and fixing portion, and the insertion opening provided in the reference attachment and fixing portion may be circular through which the bolt shaft portion of the bolt can be inserted. 【0024】 With this invention, in the reference mounting fixing part, unlike the case where the insertion opening is, for example, an elongated hole shape, the mounting position relative to the mounting location can be uniquely determined by inserting a bolt into the circular insertion opening. 【0025】 Therefore, when fastening and fixing the mounting body to the mounting location using multiple mounting fixing parts, even if the spacing between the multiple mounting fixing parts has a tolerance relative to a predetermined spacing, the reference mounting fixing part can be attached to the mounting location as a reference mounting position among the mounting positions of the multiple mounting fixing parts, where the mounting position does not change due to tolerances. 【0026】 This invention allows the mounting module to be more securely attached to the mounting location by fastening and fixing the reference mounting part with one of the bolts, even if the spacing between bolts changes from a predetermined spacing due to tolerances or expansion / contraction of the material. Furthermore, the insertion opening of the reference mounting and fixing portion may be fitted with a protective member having an insertion direction portion and a wire fixing portion, or it may be fitted with a protective member that does not have a wire fixing portion. 【0027】 In another aspect of this invention, the mounting member may be a wire harness, the mounting body may be a protector through which the wire harness is inserted, and the electric wire may be an earth wire provided on the wire harness. 【0028】 This invention allows for the protection of a wire harness, which is made up of electric wires, by inserting it into the protector and attaching the protector to the mounting location using the mounting and fixing part. This also allows for route regulation of the wiring path. Furthermore, since the ground wire of the wire harness is fixed to the wire fixing part of the protective member provided on the mounting and fixing part, the ground wire can be grounded by fastening and fixing the protector to the mounting location. [Effects of the Invention] 【0029】 According to this invention, it is possible to provide a mounting module, a mounting structure thereof, and a protective member that can be efficiently and securely attached to a mounting location while allowing current to flow through it.

[Modes for carrying out the invention] 【0031】 One embodiment of this invention will be described below with reference to the drawings. In the following description, an example will be given in which the mounting module of the invention is applied to an outer casing structure 1 for a wire harness. 【0032】 In the figure, arrow Z indicates the thickness direction of the exterior structure 1, arrow W indicates the width direction of the exterior structure 1, and arrow Y indicates the direction perpendicular to the thickness direction Z and the width direction W, i.e., the longitudinal direction of the exterior structure 1. Furthermore, in the figure, arrow Za indicates one side in the thickness direction, arrow Zb indicates the other side in the thickness direction, arrow Wa indicates one side in the width direction, arrow Wb indicates the other side in the width direction, arrow Ya indicates one side in the longitudinal direction, and arrow Yb indicates the other side in the longitudinal direction. 【0033】 As shown in Figure 1, the exterior structure 1 of this embodiment includes a protector 10 that houses the wire harness 100 and is attached to mounting locations P2a, P2b on the vehicle body, such as conductive vehicle body panels 200, and an earth wire 2 that branches off from the wire harness 100. 【0034】 The wire harness 100 has each end in the longitudinal direction Y electrically connected to various electrical devices and on-board equipment such as power supplies (batteries) mounted on the vehicle via connectors, and is equipped with multiple wires that serve as conductive paths for conducting electricity between on-board equipment, and is routed along a predetermined routing path in the vehicle. 【0035】 Multiple ground wires 2 are provided, corresponding to each of the multiple mounting fixing parts 13a and 13b. Each ground wire is branched from the wire harness 100 and extends through the lateral openings 4a and 4b to the corresponding mounting fixing part 13. The ground wire 2 has a conductor 2T covered with an insulating coating 2C, but the insulating coating 2C is stripped at the tip, exposing the conductor 2T. 【0036】 The protector 10 of this embodiment is incorporated into a vehicle such as an automobile, and is integrally formed by resin molding so that the entire structure follows the routing path of the wire harness 100. 【0037】 The protector 10 has a plate-shaped bottom surface 11 that extends in the width direction W over substantially the entire length in the longitudinal direction Y, and a pair of side wall sections 12a and 12b that rise vertically from both sides of the bottom surface 11 in the width direction W toward one side Za in the thickness direction. The protector 10 has a cross-sectional shape perpendicular to the longitudinal direction Y, which is squared U-shaped, so that it has an internal space 7 with one side Za in the thickness direction open. The protector 10 protects the wire harness 100 by housing it in its internal space 7, thereby restricting the routing direction of the wire harness 100. As shown in Figure 1, the wire harness 100 is housed in the internal space 7 along its longitudinal direction Y, and is led outwards from both sides of the protector 10 along its longitudinal direction Y. The protector 10 in this embodiment may also be appropriately equipped with a cover to cover the opening of the internal space 7. 【0038】 As shown in Figure 1, the protector 10 has multiple mounting and fixing parts 13 (13a, 13b) arranged in the longitudinal direction Y, which are attached and fixed to predetermined mounting locations P2a, P2b on, for example, the vehicle body panel 200. 【0039】 Furthermore, each of the pair of side wall portions 12a and 12b has a lateral opening 4 (4a, 4b) formed therein, where the portion corresponding to the mounting and fixing portion 13a and 13b in the longitudinal direction Y opens to the side. The lateral opening 4 has a width that allows the ground wire 2 to pass through. 【0040】 As shown in Figure 1, the protector 10 of this embodiment is equipped with two mounting and fixing parts 13a and 13b. These two mounting and fixing parts 13a and 13b are spaced apart from each other in the longitudinal direction Y of the protector 10, and are both formed to protrude from one end of the widthwise side Wa of the bottom surface 11 to the widthwise side Wa. 【0041】 Here, of the two mounting and fixing parts 13a, the mounting and fixing part 13 on one side Ya in the longitudinal direction is set as the first mounting and fixing part 13a, and the mounting and fixing part 13 on the other side Yb in the longitudinal direction is set as the second mounting and fixing part 13b. 【0042】 The mounting and fixing portions 13a and 13b have through-openings 14 (14a, 14b) formed in the thickness direction Z through which bolts B are inserted. The mounting and fixing portions 13a and 13b are fastened and fixed to the mounting locations P2a and P2b on the vehicle body panel 200 with bolts B and nuts N as fastening means. 【0043】 As shown in Figures 1, 2, and 4, the vehicle body panel 200 has mounting points P2a and P2b to which the two mounting fixing parts 13a and 13b are attached, and both of these mounting points P2a and P2b have circular insertion openings 2a and 2b through which bolts B can be inserted. 【0044】 Protective members 20 (20a, 20b) are attached to the edges of the insertion openings 14a, 14b in the mounting and fixing parts 13a, 13b to protect the mounting and fixing parts 13a, 13b from the fastening pressure of the bolt B. Furthermore, nuts N are welded to the opposite side of the mounting points P2a and P2b of the vehicle body panel 200 from the side to which the corresponding mounting fixing parts 13a and 13b are attached. The insertion openings 2a and 2b of the mounting points P2a and P2b communicate with the insertion openings of the nuts N in the thickness direction Z. 【0045】 Here, the protective member 20 attached to the first mounting and fixing part 13a is set as the first protective member 20a, and the protective member 20 attached to the second mounting and fixing part 13b is set as the second protective member 20b. 【0046】 Next, the configuration of the first mounting and fixing part 13a will be described. As shown in Figures 1 to 3, the first mounting and fixing portion 13a is fastened and fixed to the mounting locations P2a and P2b together with the first protective member 20a by bolts B and nuts N. The insertion opening 14a in the first mounting and fixing portion 13a is formed as a reference insertion opening 14a, and is formed in a perfectly circular shape through which the bolt shaft portion Bb of the bolt B (see Figures 2 and 3) can be inserted. 【0047】 As shown in Figures 1 and 2, the first protective member 20a includes a wire fixing portion 21 for fixing the conductor 2T of the ground wire 2, and a collar portion 24 positioned in the reference insertion opening 14a, as shown in Figures 1 to 3. The entire member is made of a conductive metal material such as aluminum. 【0048】 As shown in Figures 1 and 2, the wire fixing section 21 includes a coating crimping section 22 and a conductor crimping section 23. Both the coating crimping section 22 and the conductor crimping section 23 are so-called open barrels, each having a barrel piece. The coating crimping section 22 crimps the insulating coating 2C at the tip of the ground wire 2, and the conductor crimping section 23 crimps the exposed conductor 2T. The wire fixing section 21 is connected (crimped) to the exposed conductor 2T at the tip of the ground wire 2. Note that the wire fixing section 21 is not limited to an open barrel; a cylindrical closed barrel through which the tip of the ground wire 2 can be inserted may also be used. 【0049】 As shown in Figures 2 and 3, the collar portion 24 is interposed between the bolt B and the mounting location P2a on the vehicle body, and is attached to the edge of the reference insertion opening 14a of the first mounting fixing portion 13a by the fastening force of the bolt B and nut N. The collar portion 24 includes a cylindrical portion 25 that extends in the insertion direction into the reference insertion opening 14a, i.e., in the thickness direction Z, and a flange portion 26 that expands radially outward in a flange shape from the end of one side Za in the thickness direction of the cylindrical portion 25. 【0050】 The cylindrical portion 25 is formed in a cylindrical shape having an outer diameter that allows it to be inserted into the reference insertion opening 14a of the first mounting and fixing portion 13a, and an inner diameter that allows the bolt shaft portion Bb of the bolt B to be inserted. Furthermore, the cylindrical portion 25 is formed such that its projection length toward the other side Zb in the thickness direction is equal to the thickness of the first mounting and fixing portion 13a (depth of the reference insertion opening 14a) compared to the flange portion 26 on one side. 【0051】 As shown in Figure 3, when the cylindrical portion 25 of the first protective member 20a is inserted into the reference insertion opening 14a (fitted in place), the one-sided flange portion 26 is positioned on the periphery of the one-sided side Za in the thickness direction of the reference insertion opening 14a of the first mounting fixing portion 13a. That is, the one-sided flange portion 26 is positioned on the side opposite to the mounting location P2a in the thickness direction Z of the reference insertion opening 14a so as to be able to abut against the bolt head Ba of the bolt B inserted into the reference insertion opening 14a. As a result, when the first protective member 20a is attached to the first mounting fixing portion 13a, the one-sided flange portion 26 is interposed between the bolt head Ba and the first mounting fixing portion 13a. 【0052】 Furthermore, as shown in Figures 1 to 3, the flange portion 26 on one side is formed in a cylindrical shape that is radially larger than the contact portion of the bolt head Ba. Then, as shown in Figures 1 and 2, the wire fixing portion 21 extends radially outward from a part of the circumferential direction of the flange portion 26 on one side and is formed integrally with the collar portion 24. The wire fixing portion 21 consists of a conductor crimping portion 23 and a covering crimping portion 22, and the conductor crimping portion 23 is positioned so that it faces one side Ya in the longitudinal direction. 【0053】 Next, the procedure for attaching the first mounting fixing part 13a to the mounting location P2a will be briefly explained. First, the cylindrical portion 25 of the first protective member 20a is inserted into the reference insertion opening 14a of the first mounting fixing part 13a from one side Za in the thickness direction. This allows the collar portion 24 of the first protective member 20a to be attached to the first mounting fixing part 13a with the cylindrical portion 25 positioned in the reference insertion opening 14a. 【0054】 Next, the bolt shaft portion Bb of bolt B is inserted from one side Za in the thickness direction into the reference insertion opening 14a at the mounting location P2a, more precisely, into the insertion opening in the cylindrical portion 25 located in the reference insertion opening 14a. At the same time, a nut N is screwed onto the bolt shaft portion Bb that protrudes from the mounting location P2a to the other side Zb in the thickness direction. 【0055】 As described above, the fastening force of the bolt B and nut N allows the first mounting fixing part 13a to be attached to the mounting location P2a. Furthermore, since the collar portion 24 of the first protective member 20a is interposed in a bracing state between the bolt head Ba and the mounting location P2a, the collar portion 24 of the first protective member 20a protects the first mounting fixing part 13a from being damaged by the fastening force. In addition, the first protective member 20a and the mounting location P2a are electrically connected to each other, and the exposed conductor 2T at the tip of the ground wire 2 is connected to the wire fixing part 21. As a result, the ground wire 2 is grounded to the mounting location P2a. Moreover, the first protective member 20a, which functions as a ground terminal, can be easily attached to the protector 10 simply by inserting the cylindrical portion 25 into the reference insertion opening 14a. 【0056】 As shown in Figure 3, in this embodiment, when the first mounting fixing portion 13a is fastened to the mounting location P2a with bolts B and nuts N, the end Zb on the other side in the thickness direction of the cylindrical portion 25 of the first protective member 20a comes into contact with the edge of the reference insertion opening 14a of the mounting location P2a, and the first protective member 20a and the mounting location P2a come into contact via bolts B and nuts N. As a result, the first protective member 20a and the mounting location P2a become electrically connected to each other as described above. 【0057】 When the protector 10 is attached to the vehicle body, the actual mounting positions of the two mounting parts 13a and 13b to the vehicle body will have tolerances relative to their original mounting positions to the vehicle body due to factors such as machining errors in the formation of the insertion openings 2a and 2b at the mounting points P2a and P2b, and distortions that may occur in the protector 10 itself. As a result, there is a relative tolerance between the two mounting parts 13a and 13b (between the two points (13a and 13b)). 【0058】 Therefore, in this embodiment, the first mounting and fixing portion 13a is attached to the vehicle body at a predetermined mounting location at the reference insertion opening 14a, while the second mounting and fixing portion 13b is attached to the vehicle body at the insertion opening 14b in a manner that can absorb the relative tolerance between the two points (13a, 13b). 【0059】 The specific configuration of the second mounting and fixing part 13b will be described below. However, components identical to the first mounting and fixing portion 13a are denoted by the same reference numerals and their descriptions are omitted. Furthermore, the fastening position of the bolt B of the first mounting and fixing portion 13a to the vehicle body, i.e., the position of the reference insertion opening 14a, is set as the first reference fastening position. 【0060】 As shown in Figures 1, 4, and 5(a), the second mounting and fixing portion 13b is fastened and fixed to the mounting location P2b together with the second protective member 20b by bolts B and nuts N (see Figures 4 and 5(a)). 【0061】 As shown in Figures 1 and 4, the insertion opening 14b in the second mounting and fixing portion 13b extends linearly from the edge of one longitudinal side Ya of the second mounting and fixing portion 13b toward the other side Yb, i.e., toward the interior in a plan view, and is formed in a groove shape with the edge of one longitudinal side Ya open. 【0062】 As a result, as shown in Figures 1 and 4, the insertion opening 14b in the second mounting and fixing portion 13b is formed along the longitudinal direction Y at an intermediate portion in the width direction W and on one side Ya in the longitudinal direction of the second mounting and fixing portion 13b. Furthermore, the insertion opening 14b is formed with a groove width that allows the bolt shaft portion Bb of the bolt B to be inserted over the entire length in the longitudinal direction Y. 【0063】 Furthermore, the insertion opening 14b is formed along the longitudinal direction Y so as to pass through the original fastening position of the second mounting fixing part 13b to the vehicle body, that is, the fastening position of the bolt B of the second mounting fixing part 13b (hereinafter referred to as the "second reference fastening position") assuming there is no relative tolerance between the two points (13a, 13b) mentioned above. 【0064】 Furthermore, the insertion opening 14b of the second mounting and fixing portion 13b is formed such that the direction in which the imaginary straight line connecting the two points (13a, 13b) mentioned above, that is, the first reference fastening position and the second reference fastening position, extends coincides with the groove formation direction. In this embodiment, the groove formation direction is formed to coincide with the longitudinal direction Y. 【0065】 As a result, as shown in Figures 4 and 5(a), even if the fastening position of the bolt B to the vehicle body is misaligned with the second reference fastening position due to the relative tolerance between the two points (13a, 13b), the insertion opening 14b can be connected to the insertion opening 2b of the mounting location P2b in the thickness direction Z, thus ensuring secure fastening to the vehicle body using bolts B or the like. 【0066】 As shown in Figures 1, 4, and 5(a), the second protective member 20b comprises a pair. The pair of second protective members 20b have their respective collar portions 24 formed symmetrically in the width direction W, and both have a cross-sectional shape that is perpendicular to the longitudinal direction Y. 【0067】 As a result, one of the pair of second protective members 20b is positioned on the edge Wa of one side in the width direction of the insertion opening 14b of the second mounting and fixing portion 13b, and the other of the pair of second protective members 20b is positioned on the edge Wb of the other side in the width direction of the insertion opening 14b of the second mounting and fixing portion 13b, and the other side Wb of the width direction of the insertion opening 14b of the second mounting and fixing portion 13b. 【0068】 As shown in Figure 5(a), each collar portion 31 in the pair of second protective members 20b includes a vertical wall portion 32 extended in the thickness direction Z, a one-side flange portion 33 provided at the end of the vertical wall portion 32 on one side Za in the thickness direction, and a other-side flange portion 34 provided at the end of the other side Zb in the thickness direction. 【0069】 As shown in Figure 4, the vertical wall portion 32 is formed as a flat plate extending linearly along the thickness direction Z and the longitudinal direction Y. The vertical wall portion 32 is formed such that the length in the thickness direction Z between one flange portion 33 and the other flange portion 34 is equal to or greater than the thickness of the second mounting fixing portion 13b (depth of the insertion opening 14b). 【0070】 One side flange portion 33 extends from the end of one side Za in the thickness direction of the vertical wall portion 32, The other flange portion 34 protrudes horizontally in the width direction W from the end of the vertical wall portion 32 on the other side Zb in the thickness direction, opposite to the insertion opening 14b. Both the one flange portion 33 and the other flange portion 34 are formed in a flat plate shape over the entire length of the vertical wall portion 32 in the longitudinal direction Y. 【0071】 Furthermore, when attaching the pair of second protective members 20b to the second mounting and fixing part 13b, as shown in Figure 4, the collar portion 31 (vertical wall portion 32) of the pair of second protective members 20b can be inserted into the insertion opening 14b of the second mounting and fixing part 13b from the edge of one longitudinal side Ya to the other longitudinal side Yb, thereby enabling attachment as shown in Figure 1. 【0072】 In this configuration, each collar portion 31 of the pair of second protective members 20b is positioned on the edges of the insertion opening 14b in the width direction W. The bolt head Ba of the bolt B inserted through the insertion opening 14b is in contact with each of the pair of one-sided flange portions 33 of these collar portions 31. In other words, the pair of one-sided flange portions 33 are interposed between the bolt head Ba and the second mounting and fixing portion 13b. 【0073】 In this embodiment, the second protective member 20b is formed to be slightly shorter in length than the total length in the longitudinal direction Y of the groove-shaped insertion opening 14b, i.e., in the extending direction, and is attached to the edge of the insertion opening 14b in the width direction W over substantially the total length in the longitudinal direction Y. 【0074】 As a result, the second protective member 20b is interposed between the bolt head Ba and the second mounting and fixing part 13b, regardless of where the bolt B is inserted in the longitudinal direction Y of the insertion opening 14b. In other words, even if the fastening position of the bolt B to the vehicle body is misaligned with the second reference fastening position due to the relative tolerance between the two points (13a, 13b), the second mounting and fixing part 13b is securely fastened to the vehicle body by the bolt B, etc., and is connected to the ground via the second protective member 20b. 【0075】 Furthermore, as shown in Figure 4, the wire fixing portion 21 is integrally formed with the one-side flange portion 33 so as to extend from the end of the other side Yb in the longitudinal direction of the one-side flange portion 33 to the other side Yb in the longitudinal direction. 【0076】 Furthermore, when the vertical wall portion 32 of the second protective member 20b is positioned in the insertion opening 14b, the other flange portion 34 is positioned on the edge Zb on the other side in the thickness direction of the second mounting and fixing portion 13b. That is, when the second protective member 20b is attached to the second mounting and fixing portion 13b, the other flange portion 34 is interposed between the second mounting and fixing portion 13b and the mounting location P2b on the vehicle body. 【0077】 As shown in Figures 1 to 5(a), the exterior structure 1 of the above-described embodiment accommodates (mounts) the wire harness 100 and is attached to conductive mounting locations P2a and P2b. The mounting and fixing portions 13a and 13b of the protector 10 are provided with insertion openings 14a and 14b through which bolts B, which are fastened and fixed to the mounting locations P2a and P2b, are inserted. Furthermore, as shown in Figures 2 and 3, the first protective member 20a, which protects the first mounting and fixing portion 13a from the fastening pressure of the bolts B, is provided with a cylindrical portion 25 positioned in the reference insertion opening 14a. Additionally, as shown in Figures 4 and 5(a), the second protective member 20b, which protects the second mounting and fixing portion 13b from the fastening pressure of the bolts B, is provided with a vertical wall portion 32 positioned in the insertion opening 14b. 【0078】 Therefore, the mounting and fixing parts 13a and 13b can be protected from the fastening pressure of bolt B, and the exterior structure 1 can be securely attached to the mounting points P2a and P2b. 【0079】 Furthermore, the protective members 20 (20a, 20b) that are attached to the mounting fixing parts 13a, 13b while positioned in the insertion openings 14a, 14b through which the bolt B is inserted are made of conductive material and are provided with a wire fixing part 21, as shown in Figure 1. In addition, the wire fixing part 21 fixes the ground wire 2 extending from the wire harness 100. 【0080】 Then, when the mounting fixing parts 13a, 13b are fastened and fixed with bolts B to the conductive mounting points P2a, P2b, the cylindrical part 25 of the first protective member 20a, which is made of a conductive material, comes into contact with the mounting point P2a, and the first protective member 20a and the mounting point P2a become electrically connected to each other. As a result, the exposed conductor 2T at the tip of the ground wire 2 connected to the wire fixing part 21 of the first protective member 20a becomes electrically connected to the mounting point P2a. 【0081】 Furthermore, the vertical wall portion 32 of the second protective member 20b, which is made of a conductive material, comes into contact with the mounting location P2b, causing the second protective member 20b and the mounting location P2b to be electrically connected to each other. As a result, the ground wire 2 connected to the wire fixing portion 21 of the second protective member 20b becomes electrically connected to the mounting location P2b. 【0082】 In this way, by fastening the exterior structure 1 to the mounting points P2a and P2b with bolts B, the ground wire 2 extending from the wire harness 100 and the conductive mounting points P2a and P2b become electrically connected to each other, and the exterior structure 1 can be efficiently attached to the mounting points P2a and P2b in a state where it can conduct electricity. 【0083】 Furthermore, as shown in Figures 1 to 3, the first protective member 20a is provided with a flange portion 26 on one side, and the second protective member 20b is provided with a flange portion 33 on one side, and wire fixing portions 21 are provided on each of the flange portions 26 and 33. Therefore, compared to the case where the wire fixing portion 21 is directly provided on the cylindrical portion 25 of the first protective member 20a or the vertical wall portion 32 of the second protective member 20b, the wire fixing portion 21 can be provided more stably, and multiple ground wires 2 can be connected according to the number of wire fixing portions 21 provided. 【0084】 Furthermore, by bringing the bolt head Ba into contact with one side flange portion 26, 33, the protective members 20a and 20b increase the contact area with the bolt head Ba compared to when they only contact the end of one side Za in the thickness direction of the cylindrical portion 25 or the vertical wall portion 32. Therefore, the protective members 20a and 20b can more securely protect the mounting and fixing portions 13a and 13b from the fastening pressure of the bolt B. 【0085】 Furthermore, as shown in Figures 4 and 5(a), the second protective member 20b is provided with a flange portion 34 on the other side that conductively contacts the mounting location P2b. Compared to the case where the flange portion 34 is not provided, when the end of the other side Zb in the thickness direction of the vertical wall portion 32 is brought into contact with the mounting location P2b (see Figure 5(a)), the contact area with the mounting location P2b is increased, thereby improving conductivity. 【0086】 Furthermore, as shown in Figures 4 and 5(a), the second protective member 20b is configured as a pair and is positioned at opposing locations in the insertion opening 14b, allowing it to be easily positioned in insertion openings 14b formed at any spacing (groove width). 【0087】 For example, as shown in Figure 5(b), when fastening the second mounting part 13b to the mounting location P2b using a bolt B' with a different shaft diameter than the bolt B used in Figure 5(a), the second mounting part 13b has an insertion opening 14b formed at a widthwise spacing (groove width) corresponding to the shaft diameter of the bolt B'. Even in this case, the second protective member 20b can be the same size as the second protective member 20b shown in Figure 5(a) and applied to the insertion opening 14b. 【0088】 Furthermore, as shown in Figure 4, the insertion opening 14b extends inward in a plan view from the peripheral edge of the mounting and fixing portion 13a and is formed as a groove opening with an open peripheral edge. Therefore, as shown in Figures 5(a) and (b), it can be fastened and fixed with bolts B and B' of various shaft diameters corresponding to the groove width of the insertion opening 14b. Moreover, even if the fastening position by bolts B, etc. is misaligned in the extension direction of the insertion opening 14b relative to the second reference fastening position due to tolerances, etc., the second mounting and fixing portion 13b can still be fastened and fixed to the mounting location P2b using bolts B, etc. 【0089】 Furthermore, the vertical wall portion 32 of the second protective member 20b is formed along the extending direction of the groove-shaped insertion opening 14b, and in this example, extends over substantially the entire length of the insertion opening 14b. Therefore, as described above, even if the fastening position by the bolt B, etc., is misaligned with the second reference fastening position in the extending direction of the insertion opening 14b due to tolerances, etc., the second protective member 20b can be reliably interposed between the bolt B and the mounting location P2b. Consequently, the ground wire 2 connected to the wire fixing portion 21 of the second protective member 20b can be reliably grounded to the mounting location P2b. 【0090】 Furthermore, as shown in Figures 1 to 3, the exterior structure 1 is provided with multiple mounting and fixing parts 13a and 13b, one of which is designated as the first mounting and fixing part 13a, and the reference insertion opening 14a provided in the first mounting and fixing part 13a is circular in shape, allowing the bolt shaft portion Bb of the bolt B to be inserted. Therefore, even if the distance between the bolts B at the two points (13a and 13b) changes from a predetermined distance due to the relative tolerance between the two points (13a and 13b), the first mounting and fixing part 13a can be fastened and fixed to the mounting location P2a with the bolt B inserted through the circular reference insertion opening 14a, thereby more securely attaching the exterior structure 1 to the mounting locations P2a and P2b. 【0091】 Furthermore, as shown in Figure 1, the wire harness 100, which is made up of electric wires, is housed in the internal space 7 of the outer structure 1, and the outer structure 1 is attached to the mounting points P2a and P2b with the mounting fixing part 13a, thereby protecting the wire harness 100 and restricting the routing path. 【0092】 Furthermore, since the ground wire 2 of the wire harness 100 is fixed to the wire fixing portion 21 of the protective members 20a and 20b, the ground wire 2 can be grounded by fastening and fixing the mounting fixing portions 13a and 13b to the mounting locations P2a and P2b via the protective members 20a and 20b. 【0093】 In the correspondence between the configuration of this invention and the above-described embodiment, the mounting module corresponds to the exterior structure 1, and similarly The wire corresponds to ground wire 2. The mounting unit is compatible with Protector 10. The standard mounting fixing part corresponds to the first mounting fixing part 13a, The groove opening corresponds to the insertion opening 14b, The insertion direction portion corresponds to the cylindrical portion 25, The insertion direction portion corresponds to the vertical wall portion 32, The contact flange portion corresponds to the one-side flange portion 33, The flange portion corresponds to the other side flange portion 34. The mounting components are compatible with wire harness 100. The direction perpendicular to the insertion direction corresponds to the width direction W. The extension direction of the groove opening corresponds to the longitudinal direction Y, The opposite side of the mounting location in the mounting fixing part corresponds to one side Za in the thickness direction of the mounting fixing parts 13a and 13b. The peripheral edge of the mounting and fixing portion corresponds to the end of one longitudinal side Ya of the second mounting and fixing portion 13b, The interior in plan view corresponds to the other side Yb in the longitudinal direction, but this invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained. 【0094】 For example, the protective member of the present invention may have a configuration that includes a pair of collar parts 31 and three or more (three in this example) wire fixing parts 21, as shown in Figure 6, for example, protective member 20A. Specifically, the protective member 20A includes a connecting bar 3 that connects the ends Yb on the other side in the longitudinal direction of a pair of collar portions 31 in the width direction W. The ends Ya on one side in the longitudinal direction of the three wire fixing portions 21 are joined to the ends Wa on one side in the width direction W, the middle section, and the other end Wb of the connecting bar 3, respectively. 【0095】 As a result, the three wire fixing parts 21 are joined to a pair of collar parts 24 via connecting bars 3, so that each conductor crimping part 23 is arranged in parallel in the width direction W, with the conductor crimping part 23 facing one side Ya in the longitudinal direction. With the above configuration, more ground wires 2 than the number of colored sections 24 can be connected to a single mounting location P2b. 【0096】 Furthermore, when the insertion opening provided in the mounting and fixing portion of the present invention is formed in a shape that extends along the direction connecting two points (13a, 13b), it is not limited to a groove shape (see Figure 4), as in the insertion opening 14b in the second mounting and fixing portion 13b of the above-described embodiment, but may be formed in an elongated hole shape, such as the insertion opening 14c shown in Figure 7. The insertion opening 14c shown in Figures 7(a) and 7(b) is formed in a rectangular shape that is longer in the longitudinal direction Y than in the width direction W when viewed from above. 【0097】 Each collar portion 31c of the pair of protective members 20B positioned in such an insertion opening 14c has a long side portion 36 positioned along the longitudinal direction Y of the insertion opening 14c and a short side portion 37 positioned along the width direction W of the insertion opening 14c, as shown in Figure 7(a). 【0098】 Furthermore, one of the pair of protective members 20B, protective member 20Ba, is formed in an L-shape such that the end of one side Ya in the longitudinal direction of the long side portion 36 and the end of one side Wa in the width direction of the short side portion 37 are connected to each other. Furthermore, the other protective member 20Bb of the pair of protective members 20B is formed in an inverted L-shape such that the end of the other side Yb in the longitudinal direction of the long side portion 36 and the end of the other side Wb in the width direction of the short side portion 37 are connected to each other. 【0099】 The collar portion 31c has a vertical wall portion 32 and a one-sided flange portion 33 in each of its long side portion 36 and short side portion 37, without the other-side flange portion 34. Note that Figure 7(a) omits the illustration of the wire fixing portion 21 provided on each of the pair of protective members 20B. 【0100】 According to the above configuration, even if the insertion opening 14c is in the shape of a hole, the pair of protective members 20B can be easily attached to the insertion opening 14c by fitting them in from one side Za in the thickness direction. 【0101】 In the exterior structure 1 of the embodiment described above, the exposed conductor 2T of the tip of the ground wire 2 is connected to each of the two mounting fixing parts 13a and 13b. However, the mounting module of the present invention is not limited to this configuration. The reference insertion opening 14a of the mounting fixing part 13a may be fitted with a protective member having a collar part 31c and a wire fixing part 21, or it may be fitted with a protective member without a wire fixing part 21. 【0102】 In this embodiment, the insertion opening 14b is formed in a groove shape with an open edge Ya on one side in the longitudinal direction of the second mounting and fixing portion 13b. However, in the present invention, when the insertion opening is formed in a groove shape, for example, it may be formed in a groove shape with an open edge Yb on the other side in the longitudinal direction, or it may be formed in a groove shape that extends along the width direction W and has an open edge Wb on the other side in the width direction. In short, the extension direction and opening direction of the groove shape are not particularly limited. 【0103】 The protective members of the present invention are not particularly limited as long as they protect the mounting fixing portion 13 from damage due to the fastening force of the bolt B and nut N, as in the first protective member 20a and the second protective member 20b, and have the function of making conductive contact with the mounting locations P2a and P2b and connecting the exposed conductor 2T of the tip of the ground wire 2 to the ground with respect to the mounting locations P2a and P2b. For example, the collar portion 24 of the first protective member 20a may be provided with the other side flange portion 34, or the collar portion 31 of the second protective member 20b may be configured without the other side flange portion 34. 【0104】 Alternatively, the mounting locations P2a and P2b may be configured such that instead of insertion openings 2a and 2b, stud bolts (earth bolts) protruding to one side Za in the thickness direction are provided. In that case, the flange portions 26 and 33 on one side may be configured such that nuts N that are screwed onto the stud bolts inserted through the insertion openings 14a and 14b from the other side Zb in the thickness direction from Za in the thickness direction come into contact with them.
