[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-57968 Summary of the Invention [Problem to be solved by the invention]
[0004] In the above-mentioned Patent Document 1, as described above, one of the fixing parts is provided with a circular hole into which a stud bolt is inserted. Therefore, the movement of the stud bolt inserted into the circular hole is restricted by the inner peripheral surface of the circular hole. Therefore, if there is a misalignment between the stud bolt insertion hole on the mounting side and the circular hole in the fixing part, it may be difficult to fasten the stud bolt. Therefore, there is a demand for a protector that can more reliably fasten a harness fixing protector (electric wire fixing jig) to a member on the mounting side.
[0005] The present disclosure has been made to solve the above-mentioned problems, and its purpose is to provide an electric wire fixing jig that can be more reliably fastened to an attachment side member, and a vehicle that can more reliably fasten an electric wire fixing jig to an attachment side member. [Means for solving the problem]
[0006] A wire fastening jig according to a first aspect of the present disclosure is an electric wire fastening jig provided with an electric wire insertion hole into which an electric wire is inserted, and includes a first portion provided with the electric wire insertion hole and a pair of second portions provided on one side and the other side of the first portion in a first direction perpendicular to the insertion direction into the electric wire insertion hole. Each of the pair of second portions is provided with a first fastening member insertion hole into which a first fastening member for fastening the electric wire fastening jig to a predetermined first member is inserted along a second direction perpendicular to both the insertion direction and the first direction. The width of the first fastening member insertion hole provided in each of the pair of second portions in the insertion direction is larger than the width in the first direction. Note that the above width refers to the maximum width.
[0007] In the electric wire fastening jig according to the first aspect of the present disclosure, as described above, the first fastening member insertion holes provided in each of the pair of second portions have a width in the insertion direction that is larger than the width in the first direction. This allows the position of the first fastening member inserted into the first fastening member insertion hole in each of the pair of second portions to be adjusted in the insertion direction. As a result, both of the pair of second portions can be easily fastened to the predetermined first member. This allows the electric wire fastening jig to be more reliably fastened to the predetermined first member.
[0008] In the electric wire fastening jig according to the first aspect, the first fastening member insertion holes provided in each of the pair of second portions preferably have an oval shape. With this configuration, the position of the first fastening member can be easily adjusted along the longitudinal direction of the oval first fastening member insertion holes.
[0009] The electric wire fastening jig according to the first aspect preferably includes a pair of third portions provided on one side and the other side of the first portion in the first direction. Each of the pair of third portions is provided with a second fastening member insertion hole into which a second fastening member for fastening the electric wire fastening jig to a predetermined second member is inserted along the insertion direction. With this configuration, there is no need to separately provide a jig provided with the pair of second portions and a jig provided with the pair of third portions, thereby suppressing an increase in the number of parts. Furthermore, the electric wire fastening jig can be fastened using the second fastening member in addition to the first fastening member (in a direction different from that of the first fastening member).
[0010] In this case, the second fastening member insertion hole preferably has a perfect circular shape. With this configuration, the second fastening member insertion hole and the first fastening member insertion hole can be easily distinguished. As a result, it is possible to prevent the worker from making a mistake in the direction in which the electric wire fastening jig is fastened.
[0011] In the above-described electric wire fastening jig having a pair of third portions, each of the pair of third portions preferably includes a first plate member extending perpendicular to the insertion direction. This configuration allows the thickness of each of the pair of third portions in the insertion direction to be relatively small. As a result, the electric wire fastening jig can be easily made smaller.
[0012] In this case, preferably, each of the pair of second portions includes a second plate member extending perpendicular to the second direction. The first plate member and the second plate member are provided so as to be continuous with each other on each of the first portions on one side and the other side. This configuration allows the distance (size of the space) between the first plate member and the second plate member to be smaller than when the first plate member and the second plate member are spaced apart from each other. As a result, the electric wire fastening jig can be made more compact. Furthermore, the space (area) occupied by the electric wire fastening jig can be reduced.
[0013] A vehicle according to a second aspect of the present disclosure includes a vehicle body and an electric wire fastening jig having an electric wire insertion hole into which an electric wire to be wired in the vehicle body is inserted. The electric wire fastening jig includes a first portion having the electric wire insertion hole and a pair of second portions provided on one side and the other side of the first portion in a first direction perpendicular to the insertion direction into the electric wire insertion hole. Each of the pair of second portions has a fastening member insertion hole into which a fastening member for fastening the electric wire fastening jig to a predetermined member of the vehicle body is inserted along a second direction perpendicular to both the insertion direction and the first direction. The fastening member insertion hole has a width in the insertion direction that is larger than its width in the first direction. Note that the above width refers to the maximum width.
[0014] In the vehicle according to the second aspect of the present disclosure, as described above, the fastening member insertion holes provided in each of the pair of second portions have a width in the insertion direction that is larger than the width in the first direction, thereby providing a vehicle that allows the wire fastening jig to be more reliably fastened to the predetermined member. [Effects of the Invention]
[0015] According to the present disclosure, the electric wire fastening jig can be more reliably fastened to the attachment side member. [Brief explanation of the drawings]

[0017] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals, and description thereof will not be repeated.
[0018] FIG. 1 is a schematic diagram showing the configuration of a vehicle 100 according to this embodiment. The vehicle 100 includes a vehicle body 100a. The vehicle 100 also includes an electric device 10, an electric device 20, and an electric wire 30. The electric device 10 and the electric device 20 are each provided in the vehicle body 100a. The electric wire 30 is wired in the vehicle body 100a. The electric wire 30 electrically connects the electric device 10 and the electric device 20.
[0019] As shown in FIG. 2, in the vehicle 100, three (three-phase) electric wires 30 are wired in parallel with each other.
[0020] The vehicle 100 is provided with a protector 40. The protector 40 is provided to fix the electric wire 30 to a member of the vehicle body 100a (members 200 and 300 described below, see Figures 9 and 10). The vehicle 100 is provided with two protectors 40 (40A, 40B). The protectors 40A and 40B have the same configuration. The protectors 40 are made of resin. The protectors 40 (40A, 40B) are an example of an "electric wire fixing jig" of the present disclosure.
[0021] 3, the protector 40 includes a wire fixing portion 41 having a wire insertion hole 41a into which the wire 30 is inserted. The wire fixing portion 41 fixes the wire 30 inserted into the wire insertion hole 41a. The wire fixing portion 41 is an example of a "first portion" in the present disclosure.
[0022] The wire fastening portion 41 is provided with three wire insertion holes 41a corresponding to the three wires 30. The three wire insertion holes 41a are provided adjacent to one another along the X direction. The wires 30 are inserted into the wire insertion holes 41a along the Y direction perpendicular to the X direction. The X direction and the Y direction are examples of the "first direction" and the "insertion direction," respectively, in the present disclosure.
[0023] Inside the wire insertion hole 41a, a holding portion 41b is provided to hold the wire 30, which is a round wire (a wiring having a circular cross section). The holding portion 41b has a curved shape so as to fit along the outer surface of the wire 30. The holding portion 41b is provided on a cover portion 41e, which will be described later.
[0024] The protector 40 also includes a pair of plate portions 42 provided on one side (X1 side) and the other side (X2 side) of the wire fixing portion 41 in the X direction. Each of the pair of plate portions 42 is provided to extend perpendicular to the Z direction. The Z direction is a direction perpendicular to both the X direction and the Y direction. The plate portions 42 are an example of a "second plate member" and a "second portion" in the present disclosure. The Z direction is an example of a "second direction" in the present disclosure.
[0025] Each of the pair of plate portions 42 has a through hole 42a. A bolt 201 (see FIG. 9) for fastening the protector 40 (40B) to a member 200 (see FIG. 9) of the vehicle body 100a is inserted into the through hole 42a. The bolt 201 (for example, a case that houses an inverter or the like of the vehicle 100) is inserted into the through hole 42a along the Z direction. The member 200 includes a case that houses electrical equipment, circuits, and the like provided in the vehicle 100. The through hole 42a is an example of a "first fastening member insertion hole" and a "fastening member insertion hole" in the present disclosure. The bolt 201 is an example of a "first fastening member" and a "fastening member" in the present disclosure. The member 200 is an example of a "predetermined member" and a "predetermined first member" in the present disclosure.
[0026] Each of the pair of plate portions 42 is integrally formed with the electric wire fixing portion 41 (a portion of the electric wire fixing portion 41 that is included in a base portion 41d, which will be described later). Each of the pair of plate portions 42 is provided so as to extend along the X direction from an end portion 41c on the Z2 side of the electric wire fixing portion 41.
[0027] A plate-shaped reinforcing portion 43 is provided between each of the pair of plate portions 42 and the electric wire fixing portion 41. The reinforcing portion 43 stably (firmly) fixes each of the pair of plate portions 42 to the electric wire fixing portion 41. The reinforcing portion 43 is provided so as to connect the Y1-side ends of the electric wire fixing portion 41 and the plate portion 42 to each other.
[0028] 3, the protector 40 includes a pair of plate portions 44 provided on one side (X1 side) and the other side (X2 side) of the wire fixing portion 41 in the X direction. Each of the pair of plate portions 44 is provided so as to extend perpendicular to the Y direction. The plate portions 44 are an example of the "first plate member" and the "third portion" of the present disclosure.
[0029] Each of the pair of plate portions 44 has a through hole 44a. A bolt 301 (see FIG. 10) for fastening the protector 40 (40A) to a member 300 (see FIG. 10) of the vehicle body 100a is inserted into the through hole 44a. The bolt 301 is inserted into the through hole 44a along the Y direction. The member 300 includes a case that houses electrical equipment, circuits, and the like provided in the vehicle 100. The through hole 44a is an example of a "second fastening member insertion hole" in the present disclosure. The member 300 and the bolt 301 are examples of a "predetermined second member" and a "second fastening member" in the present disclosure, respectively.
[0030] 3, the plate portion 42 and the plate portion 44 are provided so as to be continuous with each other on one side (X1 side) and the other side (X2 side) of the electric wire fixing portion 41 in the X direction. Specifically, the Z2-side end 44b of the plate portion 44 and the Y2-side end 42b of the plate portion 42 are connected to each other. The plate portion 44 is formed integrally with the plate portion 42. That is, each of the pair of plate portions 42 and the pair of plate portions 44 is formed integrally with the electric wire fixing portion 41 (a portion of the electric wire fixing portion 41 that is included in a base portion 41d, which will be described later).
[0031] A plate-shaped reinforcing portion 45 is provided between the plate portion 42 and the plate portion 44, which are continuous with each other. The reinforcing portion 45 stably (firmly) fixes the plate portion 44 to the plate portion 42. The reinforcing portion 45 is provided so as to connect the ends of the plate portion 42 and the plate portion 44 opposite to the electric wire fixing portion 41.
[0032] In conventional protectors, if the fastening holes on the mounting side are misaligned with the fastening holes (circular holes) on the protector, it can be difficult to fasten the mounting side and the protector with the stud bolt. Therefore, it is desirable to more reliably fasten the protector to the mounting side.
[0033] 4, in this embodiment, the through-hole 42a provided in each of the pair of plate portions 42 has a width W1 (inner diameter) in the Y direction that is larger than a width W2 (inner diameter) in the X direction. The maximum value of the width W1 in the Y direction of the through-hole 42a is larger than the maximum value of the width W2 in the X direction. The width W1 is maximum at the center of the through-hole 42a in the X direction. The width W2 is also maximum at the center of the through-hole 42a in the Y direction.
[0034] Width W1 is larger than the sum of the tolerance of electric wire 30 and diameter R1 (see FIG. 5) of bolt portion 201a (see dashed line in FIG. 5) of bolt 201. This allows through hole 42a to absorb the tolerance of electric wire 30 (alleviate the effect of the tolerance) and also alleviate the reaction force of electric wire 30. Width W2 is larger than diameter R1 of bolt 201 and smaller than the above sum.
[0035] The through-hole 42a has an oval shape (elliptical shape). Specifically, the through-hole 42a has a circular shape with the Y direction as the longitudinal direction and the X direction as the lateral direction when viewed along the Z direction.
[0036] As shown in FIG. 5, the through-holes 42a are provided so as to extend along the Z direction without being inclined relative to the Z direction.
[0037] 6, the through-hole 44a provided in each of the pair of plate portions 44 has a perfect circular shape. The through-hole 44a has a circular shape with a radius R2 when viewed along the Y direction. The diameter of the through-hole 44a (2×R2) is approximately equal to the width W2 of the through-hole 42a (see FIG. 4).
[0038] As shown in FIG. 7, the through-holes 44a are provided so as to extend along the Y direction without being inclined relative to the Y direction.
[0039] 8, the protector 40 includes a base portion 41d and a cover portion 41e. The base portion 41d is provided with a plurality of cutout portions 41f that form the electric wire insertion holes 41a (see FIG. 3). The open side of each of the plurality of cutout portions 41f is closed (blocked) by the cover portion 41e, thereby forming the plurality of electric wire insertion holes 41a.
[0040] The base portion 41d is provided with two fitting holes 41g. The cover portion 41e is provided with claws 41h at both ends in the X direction, protruding toward the fitting holes 41g. The claws 41h fit into the fitting holes 41g, thereby fixing the cover portion 41e to the base portion 41d.
[0041] Furthermore, two protrusions 41i protruding in the Z2 direction are provided on the end surface on the Z2 side of the cover portion 41e.
[0042] Each of the plate portion 42 and the plate portion 44 is included in the base portion 41d.
[0043] In addition, in the manufacturing process of the vehicle 100, it is preferable that the electric wire 30 is assembled to the protector 40A (see FIG. 10) and then the electric wire is assembled to the protector 40B (see FIG. 9). In this way, fastening using the through hole 42a, which can absorb the tolerance of the electric wire 30, is performed after fastening using the through hole 44a. As a result, it is possible to effectively alleviate the reaction force acting on the electric wire 30 in the extension direction of the electric wire 30 due to the tolerance of the electric wire 30.
[0044] As described above, in this embodiment, the width W1 of the through hole 42a provided in each of the pair of plate portions 42 in the insertion direction (Y direction) is larger than the width W2 in the X direction. This allows a relatively large amount of position adjustment of the bolt 201 in the insertion direction in the through hole 42a.
[0045] In the above embodiment, an example has been shown in which the protector 40 includes a pair of plate portions 44, but the present disclosure is not limited to this. The protector 40 does not have to include a pair of plate portions 44.
[0046] In addition, in the above embodiment, an example has been shown in which the protector 40A and the protector 40B are fastened to different members (200, 300), but the present disclosure is not limited to this. The protector 40A and the protector 40B may be fastened to a common member.
[0047] In addition, in the above embodiment, an example in which the through-hole 44a has a perfect circular shape has been described, but the present disclosure is not limited to this. The through-hole 44a may have an oval shape. Furthermore, the through-hole 44a may have, for example, a square shape.
[0048] In addition, in the above embodiment, an example has been shown in which the plate portion 42 and the plate portion 44 are provided contiguously with each other, but the present disclosure is not limited to this. The plate portion 42 and the plate portion 44 may be spaced apart from each other and may not be provided contiguously.
[0049] In addition, in the above embodiment, an example was shown in which the through-hole 42a has an oval shape when viewed along the Z direction, but the present disclosure is not limited to this. The through-hole 42a may have, for example, a rectangular shape when viewed along the Z direction.
[0050] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present disclosure is defined by the claims, not by the description of the above embodiments, and is intended to include all modifications within the meaning and scope of the claims.
