Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fixing part fixing structure for fixing a fixing part such as a protector to two fixing points having different angles of a fixing member such as a body panel of an automobile.
[0002]
[Prior art]
For example, many long members such as wire harnesses and cables are wired in automobiles, and the long members include not only straight portions but also bent portions, and a plurality of protectors for protecting the bent long members are provided. In addition, a plurality of brackets such as a connector bracket to which connectors for connecting these long members are attached are provided.
[0003]
These parts such as a protector and a bracket are fixed parts that are fixed to a fixing member such as a vehicle body panel, and there are a plurality of fixed parts that are fixed at, for example, two places. When the fixing parts are fixed at two locations, if clips are used at both locations, there may be a problem in strength when used for a long time. In addition, when fixing is performed using a stat bolt at both locations, there is no problem in strength, but an operation of fastening screws at two locations is required, and workability is deteriorated. For this reason, it has been proposed to use a clip at one location and a stat bolt at the other location, and by using the clip and the stat bolt together in this way, screwing is only required at one location. Workability is improved and there is no worry about strength.
[0004]
[Problems to be solved by the invention]
By the way, a fixing member such as a vehicle body panel may not be composed of only one plane, but adjacent surfaces may be bent at an obtuse angle, and fixing components may be fixed over two planes having different angles. The two fixing directions are, for example, directions orthogonal to the fixing surface. That is, when fixing using a clip, a part of the clip is inserted into, for example, the engagement hole, and a part of the clip is brought into contact with the wall surface having the engagement hole to engage and fix the clip. The engagement direction is a direction substantially orthogonal to the surface to be fixed. When using a stat bolt, the stat bolt is fixed to the fixing member so that the longitudinal direction of the stat bolt is substantially perpendicular to the surface to be fixed, and a bolt insertion hole provided in the fixing component is provided on the stat bolt. Engagement (with a stat bolt inserted in the bolt insertion hole) and screwing with a nut and tightening to fix, the engagement (insertion) direction is almost orthogonal to the surface to be fixed Direction.
[0005]
As described above, since both directions are substantially perpendicular to the plane and the two fixing directions are not the same direction (parallel), both the engagement hole for engaging the clip and the bolt insertion hole for inserting the stat bolt are provided. If it is formed to have a diameter substantially the same as the diameter of the engaging portion, it is impossible to simultaneously engage the clip and insert the stat bolt into the bolt insertion hole. In other words, when the fixed part is moved in the clip engagement direction, the stat bolt moves in an inclined state with respect to the axial direction of the bolt, so the bolt insertion hole has a circular shape with a diameter considerably larger than the outer diameter of the stat bolt. Had to form. That is, the engagement hole is formed as a so-called fool hole.
[0006]
When fixing the fixing part to two surfaces with different angles, if the clip is erected on the side wall of the fixing part, it is difficult to see the positioning of the clip in the engagement hole. After engaging the joint hole, after positioning the clip in the clip engagement hole, move the fixed part along the clip engagement direction, engage the clip, and then screw the nut onto the stat bolt When the clip is positioned with the bolt engaging hole engaged with the stat bolt, the bolt engaging hole is formed to be considerably larger than the outer diameter of the stat bolt (in the fool hole). Therefore, it is difficult to position the clip and workability is poor.
[0007]
Therefore, the present invention has been made in view of such a situation, and an object of the present invention is to provide a fixing structure for a fixing part that can easily fix the fixing part.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the fixing structure of the fixing part of the present invention comprises two fixing points having different angles of a fixing member such as a vehicle body panel, one using a clip and the other using a stat bolt. It is a structure that fixes fixed parts such as
A bolt fixing means for fixing using the stat bolt includes a stat bolt fixed to the other fixing location along a direction substantially perpendicular to the fixing location, a nut screwed to the stat bolt, and the like. A fastening member and a bolt insertion hole provided in the fixed part and into which the stat bolt is inserted,
When the bolt insertion hole is brought into contact with the peripheral surface of the stat bolt on the side of the inner wall forming the bolt insertion hole close to the fixing side of the clip, the clip is fixed to one of the fixing points or the fixing part. The elongated hole is positioned at the engagement position and allows movement of the stat bolt in a direction away from the fixed side of the clip.
[0009]
By configuring in this way, the clip is brought into contact with the peripheral surface of the stat bolt fixed to the fixing member with the inner wall close to the fixing side of the clip of the bolt insertion hole of the fixing component, so that the clip is fixed to one fixing point or the fixing component. Since it can be positioned at the engagement position, it can be easily fixed by a clip. In addition, since the bolt insertion hole is a long hole that allows movement in one direction away from the fixed side of the clip of the stat bolt, the bolt moves through the long hole even when the stat bolt is inclined with respect to the axial direction. Therefore, the location where the bolt insertion hole of the fixing component is provided together with the fixing (engagement) of the clip can be brought into contact with the other fixing location of the fixing member. Therefore, the fixing part can be easily fixed.
[0010]
In addition, the fixing structure of the fixing component of the present invention is to fix the fixing component such as a protector at two fixing points having different angles of a fixing member such as a vehicle body panel, one using a clip and the other using a stat bolt. A structure to
The bolt fixing means for fixing using the stat bolt includes a stat bolt fixed to the fixing component so as to follow a direction substantially perpendicular to the other fixing portion, a nut screwed to the stat bolt, and the like A fastening member and a bolt insertion hole provided in the other fixing portion and into which the stat bolt is inserted;
When the bolt insertion hole is brought into contact with the peripheral surface of the stat bolt on the side of the inner wall forming the bolt insertion hole that is far from the fixing side of the clip, the clip is fixed to one of the fixing points or the fixing part. The elongated hole is positioned at an engagement position and allows movement of the stat bolt in a direction approaching the fixed side of the clip.
[0011]
By configuring in this way, the clip is brought into contact with the inner wall far from the fixing side of the clip of the bolt insertion hole of the fixing member by contacting the peripheral surface of the stat bolt fixed to the fixing component, so that the clip is fixed to one fixing point or the fixing component. Since it can be positioned at the engagement position, it can be easily fixed by a clip. In addition, since the bolt insertion hole is a long hole that allows movement in a direction approaching the fixed side of the clip of the stat bolt, the stat bolt moves in the long hole even when it is inclined with respect to the axial direction. In addition to the fixing (engagement) of the clip, the portion provided with the stat bolt of the fixing component can be brought into contact with the other fixing portion of the fixing member. Therefore, it is possible to fix the fixed component with simple workability.
[0012]
It is preferable that the long hole is formed in a shape that allows movement of the stat bolt only along the extending direction of the fixed component when the fixed component is fixed to a fixing member. Item 3).
As a result, the movement of the fixed part in a state where the stat bolt is inserted into the bolt insertion hole is in the direction along the extending direction of the fixed part. Since the bolt can be brought into contact with a predetermined inner wall of the bolt insertion hole, the clip can be easily positioned at one fixing portion of the clip or the engaging position of the fixing component, and the fixing component can be fixed more easily.
[0013]
The fixing portion of the fixing member is a flat portion formed in a flat shape, and the portion fixed to the fixing portion of the fixing component is formed in a flat shape in surface contact with the flat portion. (Claim 4).
As a result, the contact state between the fixing member and the fixing component is improved, so that the fixing component can be fixed stably with simple workability.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 to 5 are views showing a fixing structure of a fixing component according to the present invention. 1 to 5, reference numeral 1 denotes a fixing member. The fixing member 1 is, for example, a vehicle body panel fixed in an automobile. The vehicle body panel 1 is not only a single plane, but is curved or bent, and is adjacent to two plane portions (first and second plane portions) having different angles (bent at an acute angle). Some of the fixing parts 4 are fixed over two or three.
[0015]
Examples of the fixed component 4 include a protector that protects a long member such as a wire harness and a cable that are arranged in the automobile, and a bracket such as a connector bracket to which a connector that connects these long members is attached. In this embodiment, a protector will be described.
[0016]
The protector 4 protects a bent portion that bends or curves rather than protects a straight portion of a long member, for example, a wire harness (not shown).
Specifically, the protector 4 is formed by integrally forming a lid 6 on the wire harness housing 5 via a coupling hinge (not shown) by injection molding using a synthetic resin as a material. In addition, you may form the wire harness accommodating part 5 and the cover body 6 separately.
[0017]
The wire harness housing part 5 is composed of three parts, ie, first, second, and third housing parts 7, 8, and 9, which are bent at two acute angles on the same plane. 3 housing part 9 is arranged substantially in parallel. The first, second, and third accommodating portions 7, 8, and 9 are respectively flat plate-like bottom walls 7a, 8a, and 9a, and first and second side walls 7b, 7c, 8b, and 8c that are erected on both sides thereof. 9b and 9c are integrally formed in a substantially concave section. The widths of the bottom walls 7a, 8a, 9a and the heights of the first and second side walls 7b, 7c, 8b, 8c, 9b, 9c are arbitrarily determined depending on the wire harness to be accommodated.
[0018]
One of the first and second side walls 7b, 7c, 8b, 8c, 9b, 9c, and the upper end (bottom wall) of any one of the first, second, and third accommodating portions 7, 8, 9 A lid 6 that closes the wire harness housing portion 5 is joined to the end of the wire harness housing portion 5 via a coupling hinge. The lid body 6 closes the entire wire harness housing portion 6, but may be composed of three lid bodies that individually close the first, second, and third housing portions 7, 8, and 9.
[0019]
The first housing portion 7 and the third housing portion 9 of the protector 4 are respectively fixed to the fixing portions of the two first and second flat portions 2 and 3 that are bent at an acute angle of the vehicle body panel 1. Of these two fixing means, one is the clip fixing means 10 and the other is the bolt fixing means 11, and these fixing means 10, 11 may be provided at either fixing location. (1 plane part) 2 and the first accommodating part 7 may be fixed by the clip fixing means 10.
[0020]
The clip fixing means 10 is provided, for example, so as to protrude from a substantially circular engagement hole 12 provided in the first flat surface portion 2 and one side wall (first side wall) 7 b of the first housing portion 7 of the protector 4. Clip 13.
The clip 13 is a columnar base portion 14 that protrudes along a direction substantially perpendicular to the surface from the surface integrally with a flexible elastic member on the first side wall 7b, and the tip of the base portion 14 And a frustoconical protrusion 15 provided on the same axis.
[0021]
The base portion 14 is formed to have a diameter that is substantially the same as, slightly larger or smaller than the diameter of the engagement hole 12 of the first plane portion 2, and substantially the same as the length of the engagement hole 12 (the thickness of the first plane portion 2). It is formed to the same length.
The protrusion 15 is formed so that the diameter of the portion (large diameter portion 15a) in contact with the base portion 14 is larger than the diameter of the engagement hole 12, and can be press-fitted into the engagement hole 12 by elastic deformation. (Small diameter part) The diameter of 15b is formed to be slightly smaller than the diameter of the base part 14, and is formed into a truncated cone shape gradually reduced in diameter from the large diameter part 15a to the small diameter part 15b. When the projection 15 is elastically deformed and inserted into the engagement hole 12 by being press-fitted into the engagement hole 12, and the projection 15 penetrates the engagement hole 12, the projection 15 returns to its original shape and the large diameter portion 15a. Is in contact (engagement) with one surface of the first flat surface portion 2 (the surface opposite to the surface on which the protector 4 is fixed) and the outer surface of the first side wall 7b is the other surface of the first flat surface portion 2. Clip 13 (first housing portion 9 of protector 4) in contact with the surface (surface contact) It is adapted to be locking (fixed) to the first planar portion 2.
[0022]
In addition, the engagement hole 12 is provided in the first plane part 2 and the clip 13 is provided in the first side wall 7b of the first housing part 7 of the protector 4. Conversely, the clip is provided in the first plane part 2 and the protector is provided. The clip fixing means may be configured by providing an engagement hole in the first side wall 7 b of the four first accommodating portions 7.
[0023]
The bolt fixing means 11 fixes the other flat surface portion (second flat surface portion) 3 and the third accommodating portion 9 of the protector 4.
The first side wall 9b of the third housing portion 9 of the protector 4 is integrally provided with a contact portion 16 that contacts the second flat surface portion 3 when the protector 4 is fixed to the vehicle body panel 1.
[0024]
The contact portion 16 has a rectangular contact plate 17 in surface contact with the surface of the second flat surface portion 3, and contact plates on both sides of the contact plate 17 (both sides in the extending direction of the protector 4). 17 and a pair of side wall plates 18, 19 respectively connected to the first side wall 9 b of the third housing portion 9 and formed in a substantially U-shaped cross section. Yes.
The abutting portion 16 (the abutting plate 17 and the pair of side flat plates 18, 19) is, for example, along the lower side of the bottom wall 9a of the third accommodating portion 9 (from the upper end portion of the first side wall 9b toward the bottom wall 9a). The first side wall 9b is formed to extend approximately half the height of the first side wall 9b. A bolt insertion hole 20 of the bolt fixing means 11 is provided at a substantially central portion in the height direction of the extending portion of the contact plate 17 (the height direction of the first side wall 9b).
[0025]
The bolt fixing means 11 includes, for example, a stat bolt 21 fixed to the second flat surface portion 3, a fastening member (not shown) such as a nut screwed to the stat bolt 21, and a contact portion of the third housing portion 9. 16 is formed in a bolt insertion hole 20 into which a stat bolt 21 is inserted.
[0026]
The stat bolt 21 extends along a direction substantially orthogonal to the second flat surface portion 3 and is fixed to the second flat surface portion 3 by, for example, welding. The length of the stat bolt 21 is fastened to the stat bolt 21 penetrating the bolt insertion hole 20 when the abutting plate 17 is brought into contact with the second flat surface portion 3 with the stat bolt 21 being inserted into the bolt insertion hole 20. It is formed in a dimension that allows the members to be screwed together and tightened.
The fastening member is fixed to the second flat surface portion 3 via the contact plate 17 by being screwed and fastened to the stat bolt 21 and is, for example, a nut.
[0027]
The bolt insertion hole 20 is formed so that a nut that is a fastening member and screwed into the stud bolt 21 does not pass through while the stud bolt 21 is inserted. In addition, the bolt insertion hole 20 is the inner wall that forms the bolt insertion hole 20 and the inner wall closest to the clip 13 is brought into contact with the peripheral surface of the stat bolt 21 (in the illustrated example, or the vicinity thereof). The clip 13 is formed in a long hole that can be positioned substantially coaxially with the engagement hole 12.
This long hole is preferably formed in a shape that allows movement only in one direction in which the inserted stat bolt 21 is separated from the clip 13, specifically, only in the extending direction of the protector 4, for example. .
[0028]
Further, while the stat bolt 21 is fixed to the second plane portion 3 and the bolt insertion hole 20 is provided in the contact portion 16 (contact plate 17), the contact plate 17 of the contact portion 16 extends conversely. A stat bolt is fixed to a substantially central portion in the height direction of the portion, for example, by welding or the like along a direction substantially perpendicular to the contact plate 17 (second flat portion 3), and a bolt is inserted into the second flat portion 3. You may make it comprise a bolt fixing means by providing a hole. In this case, the bolt insertion hole is positioned substantially coaxially with the engagement hole when the peripheral surface of the stat bolt is brought into contact with the inner wall that forms the bolt insertion hole and is the farthest inner wall of the clip. It is made to form in the long hole to obtain. Moreover, it is preferable to form this long hole in a shape that allows movement only in one direction in which the inserted stat bolt approaches the clip, specifically, for example, along the extending direction of the protector.
[0029]
In order to fix the protector 4 to the vehicle body panel 1, first, as shown in FIGS. 1 to 4, as shown in FIG. 1 to FIG. The nearest inner wall is brought into contact with the peripheral surface of the stat bolt 21 (in the illustrated example, the tip (or the vicinity thereof)). When the tip portion (protrusion 15) of the clip 13 is brought into contact with or brought into contact with the first flat surface portion 2 in this manner, the clip 13 is in a position where it can be positioned substantially coaxially with the engagement hole 12.
[0030]
For this reason, when the stat bolt 21 is brought into contact with the inner wall closest to the clip of the inner wall forming the bolt insertion hole 20 and the clip 13 is brought into contact with the first flat portion 2, it can be easily positioned on the engagement hole 12. . Further, even when the clip 13 is not positioned on the engagement hole 12, the protector 4 is rotated about the stat bolt 21 while the stat bolt 21 is in contact with the inner wall forming the bolt insertion hole 20. Thus, the clip 13 can be easily positioned on the engagement hole 12. That is, since the engagement hole 12 is positioned on the rotation of the projection 15 of the clip 13 when the protector 4 is rotated about the stat bolt 21, the projection 15 of the clip 13 is moved to the first plane portion 2. When the protector 4 is rotated in contact with the outer surface, when the protrusion 15 of the clip 13 is positioned on the engagement hole 12, the tip end portion of the protrusion 15 enters (falls) into the engagement hole. The clip 13 can be positioned on the engagement hole 12. In particular, when the clip 13 is brought into contact with the first flat surface portion 2, it is not known where the clip 13 is in contact with the first flat surface portion 2, and the bolt insertion hole is formed in the fool hole. In some cases, it is difficult to position the clip 13 on the engagement hole 12.
[0031]
In addition, when a stat bolt is fixed to the extending portion of the abutting plate 17 of the abutting portion 16 and a bolt insertion hole is provided in the second plane portion 3 to constitute a bolt fixing means, By bringing the peripheral surface of the bolt into contact with the inner wall farthest from the clip among the inner walls forming the bolt insertion hole, the clip 13 can be easily positioned on the engagement hole 12 in the same manner as described above.
[0032]
In this way, the entire protector 4 is shown in the engagement direction of the clip 13 in a state where the inner wall forming the bolt insertion hole 20 is brought into contact with the stat bolt 21 and the clip 13 is positioned on the engagement hole 12 as shown in FIG. Move along arrow A direction. That is, the entire protector 4 is pressed against the first plane portion 2.
[0033]
As a result, the clip 13 is press-fitted into the engagement hole 12. That is, the protrusion 15 of the clip 13 is elastically deformed and inserted into the engagement hole 12, the protrusion 15 passes through the engagement hole 12, and returns to the original shape, and the large diameter portion 15a of the protrusion 15 is the first plane. The clip 13 is brought into contact with (engaged with) one surface of the portion 2 and the outer surface of the first side wall 7b is brought into contact (surface contact) with the other surface of the first flat portion 2 so that the clip 13 The first accommodating portion 7 of the protector 4 is fixed to the first flat surface portion 2 of the vehicle body panel 1.
[0034]
In addition, the abutting plate 17 of the abutting portion 16 comes into surface contact with the second flat surface portion 3 together with the engagement (fixation) between the clip 13 and the engaging hole 12. That is, since the bolt insertion hole 20 is formed in a shape that allows the inserted stat bolt 21 to move away from the clip 13, it interferes with the contact of the contact portion 16 with the second flat surface portion 3. Never become. That is, when the contact plate 17 comes into surface contact with the second flat surface portion 3, the stat bolt 21 is positioned at a position separated from the nearest inner wall of the clip 13.
[0035]
Then, in a state where the contact plate 17 is in contact with the second flat surface portion 3, for example, a nut as a fastening member is screwed and tightened to the stat bolt 21 penetrating the bolt insertion hole 20, so that the contact plate 17 is interposed via the contact plate 17. Thus, the third housing portion 9 of the protector 4 is fixed to the second flat surface portion 3 of the vehicle body panel 1. At this time, since the bolt insertion hole 20 is provided in the extending portion of the contact plate 17, compared to the case where the bolt insertion hole 20 is provided in the contact plate 17 facing the first side wall portion 9b. The nut can be easily attached (screwed) to the stat bolt 21 and tightened.
[0036]
Therefore, the fixing part fixing structure of the present invention allows the clip 13 to be easily positioned at the engaging position by bringing the inner wall of the bolt insertion hole into contact with the peripheral surface of the stat bolt 21, and the clip 13 remains in this state. Since the abutting plate 17 can be brought into contact (surface contact) with the second flat surface portion 3 while allowing the stat bolt 21 to pass through the bolt insertion hole 20 together with the fixing by the above, the next work is fastening the nut etc. to the stat bolt 21 Since the protector 4 is fixed to the vehicle body panel 1 simply by screwing and tightening the members, the protector 4 can be easily fixed.
[0037]
Further, when the bolt insertion hole 20 is formed as a long hole that allows the inserted stat bolt 21 to extend only in the extending direction of the protector 4, that is, in only one direction, the stat bolt 21 is inserted into the bolt. A location near or far from the clip 13 on the inner wall of the hole 20 can be easily contacted. That is, since the movement of the protector 4 in a state where the stat bolt 21 is inserted into the bolt insertion hole 20 is only in one direction along the extending direction of the protector 4, the protector 4 is guided and slid by the bolt insertion hole 20. Only, the stat bolt 21 can be reliably brought into contact with a predetermined inner wall of the bolt insertion hole 20. Therefore, the clip 13 can be more easily positioned on the engagement hole 12, and the protector 4 can be fixed more easily.
[0038]
Further, the first side wall 7b of the first housing portion 7 of the protector 4 and the first flat surface portion 2 of the vehicle body panel 1 are in surface contact, and the contact plate 17 of the third housing portion 9 of the protector 4 and the vehicle body panel 1 are in contact with each other. Since the protector 4 is fixed to the vehicle body panel 1 in a state where the second flat surface portion 3 is in surface contact, the contact state between the protector 4 and the vehicle body panel 1 becomes good, so that the workability is simple and stable. The protector 4 can be reliably fixed.
