[0013]
――― Piping support method ―――
4 to 7, a method of supporting the pipe by attaching the rubber grommet 100 and the resin cap 200 to the pipe and fixing it to the panel opening will be described. FIG. 4 is a diagram showing a state where the pipes 10 and 20 are sandwiched between the rubber grommet 100 and the resin cap 200. The pipes 10 and 20 are arranged in two stages vertically in the front-rear direction of the vehicle, and are connected to equipment (not shown) while penetrating an opening 31 opened in a panel 30 of the vehicle. Even if both ends of the pipes 10 and 20 are already connected to equipment and the like, since the rubber grommet 100 is made of soft rubber, the cut surface 101 can be opened to sandwich the pipes 10 and 20. Similarly to the rubber grommet 100, the resin cap 200 can be opened right and left from the top of each of the cylinders 210 and 220 to sandwich the pipes 10 and 20. The rubber grommet 100 sandwiches the pipes 10 and 20 such that the pipe 10 passes through the upper through-hole 151 and the pipe 20 passes through the lower through-hole 152.
[0014]
FIG. 5 shows a state in which the rubber grommet 100 sandwiches the pipes 10 and 20, then moves the rubber grommet 100 to the opening 31 opened in the panel 30, and inserts the rubber grommet 100 into the opening 31 to temporarily fix the pipes 10 and 20. FIG. The rubber grommet 100 inserted into the opening 31 holds the panel 30 from both front and back sides by the left and right rear locking portions 111 and 131 and the left and right front locking portions 112 and 132, and the rubber grommet 100 and the pipes 10 and 20. Is fixed to the panel 30.
[0015]
FIG. 6 is a view showing a state where the resin cap 200 is inserted into the rubber grommet 100 from the state of FIG. 5 and the pipes 10 and 20 are fixed to the panel 30. FIG. 7 is a cross-sectional view as viewed from plane VII-VII in FIG. The resin cap 200 is inserted into the groove 120 of the rubber grommet 100 as described above. When the resin cap 200 is further pushed into the rubber grommet 100 after the flange portion 207 of the resin cap 200 hits the rubber grommet 100, the claw 208 of the resin cap 200 is locked in the opening 31 as shown in FIG. . The claws 208 of the resin cap 200 penetrate through holes 107 provided in the upper grooves 121 and 126 of the rubber grommet 100 and penetrating from the front to the back of the rubber grommet 100. In this state, the locking portion 218 of the claw 208 comes into contact with the panel 30, and the locking portion 217 of the flange 207 presses the rubber grommet 100. The same applies to the claws 209. This restricts the rubber grommet 100 from moving in the axial direction of the pipe 10 and prevents the rubber grommet 100 from coming off the panel 30. In addition, the resin cap 200 inserted into the groove 120 suppresses the deformation of the soft rubber grommet 100 and prevents the rubber grommet 100 from opening at the cut surface 101. Further, as described above, the tip portions of the claws 208 and 209 are inclined inward. However, since the claws 208 and 209 are pushed outward by the pipes 10 and 20 via the rubber grommet 100, the resin cap 200 is securely inserted into the opening 31. Can be locked. 7, the nail 208 presses the inner surface of the upper through hole 151 of the rubber grommet 100 against the pipe 10 by elasticity. The same applies to the claws 209. In the grommet structure of the present embodiment, the number of fixed pipes may be one or three or more. Further, even when a plurality of pipes are fixed, the pipe diameters do not need to be all the same, and pipes having different diameters may be used.
[0016]
The grommet structure according to the first embodiment has the following advantages.
(1) The rubber grommet 100 can open the cut surface 101 to sandwich the pipes 10 and 20. Similarly to the rubber grommet 100, the resin cap 200 can be opened right and left from the top of each of the cylinders 210 and 220 to sandwich the pipes 10 and 20. Thereby, even if both ends of the plurality of pipes are already connected to equipment or the like, the rubber grommet 100 and the resin cap 200 can be attached to these pipes, and the pipes can be reliably fixed to the panel in a short time.
(2) Since the resin cap 200 is harder than the rubber grommet 100, deformation of the soft rubber grommet 100 can be suppressed by the resin cap 200 inserted into the groove 120, so that the rubber grommet 100 can be prevented from opening at the cut surface 101. As a result, the pipe can be securely fixed, and it is possible to prevent the cut surface from opening and the appearance from being deteriorated.
(3) The tips of the claws 208 and 209 of the resin cap 200 are inclined inward, and when the resin cap 200 is inserted into the rubber grommet 100, the claws press the inner surface of the through hole of the rubber grommet 100 against each pipe by elasticity. Thereby, the displacement of each pipe in the axial direction can be prevented, and the pipe can be securely fixed.
(4) Since a plurality of pipes having different diameters can be fixed at the same time, the pipes can be reliably fixed to the panel with a small number of parts. As a result, it is possible to reduce the working time, the number of parts, and the cost in the assembly process.

FIG. 11 is a sectional view taken along line XX of FIG. The resin cap 400 has a low-cap shape with a hole 402 opened at the center of the cap body 401. As shown in FIG. 10B, the cap body 401 is cut at a cut portion (opening) 403 extending radially from the hole 402. When the cap body 401 is used, the opening 403 is closed and FIG. The cap body 401 has an integral structure shown in FIG. Two claws 408 are provided inside the cap body 401. On one end surface of the opening 403, a trapezoidal projection (ant) 404 having a wide tip is provided. On the other end surface of the opening 403, a trapezoidal concave portion (dovetail groove) 405 having a narrow end surface side is provided. As will be described later, when the cap body 401 is mounted on the pipe, the trapezoidal convex portion 404 and the trapezoidal concave portion 405 engage to maintain the circular shape of the cap body 401. D in FIG. 10C is the distance that the outer peripheral portion 406 protrudes from the rear surface of the cap body 401. The relationship with the thickness t of the front locking portion 312 of the rubber grommet 300 is as follows.

[0020]
――― Piping support method ―――
With reference to FIGS. 11 to 15, a method of attaching the rubber grommet 300 and the resin cap 400 to the pipe and supporting the pipe at the opening of the panel will be described. FIG. 11 is a view showing the pipe 40, and FIG. 12 is a view showing a state where the pipe 40 is sandwiched between the rubber grommet 300 and the resin cap 400. The pipe 40 is provided in the front-rear direction of the vehicle, and is connected to a device (not shown) while passing through an opening 51 formed in a panel 50 of the vehicle. The pipe 40 is provided with a groove 41 on the outer periphery of the pipe 40. Even if both ends of the pipe 40 are already connected to the device or the like, the rubber grommet 300 and the resin cap 400 can cut the cutting line CL and the cutting portion 403 similarly to the rubber grommet 100 and the resin cap 200 of the first embodiment. The pipe 40 can be opened to sandwich the pipe 40. When the rubber grommet 300 is sandwiched between the pipes 40, the grooves 41 of the pipe 40 and the protrusions 355 of the rubber grommet 300 are fitted as shown in FIG.
[0021]
FIG. 14 is a perspective view showing a state in which the rubber grommet 300 is inserted into the panel opening 51 from the state shown in FIGS. FIG. 15 is a cross-sectional view of FIG. 14, and shows a state where the pipe 50 is cut along a surface where the claw 408 is located in the axial direction. The rubber grommet 300 is locked while holding the panel 50 between the rear locking portion 311 and the front locking portion 312. As shown in FIG. 15, the claw tip 418 engages with the through-hole locking portion 317 of the rear locking portion 311. Further, at this time, from the relationship of the above-described formula (1), a state is established in which there is a gap 55 between the front surface of the panel 50 and the outer peripheral portion 406 of the resin cap 400. That is, the resin cap 400 sandwiches the panel 50 via the rear locking portion 311 and the front locking portion 312 of the rubber grommet 300 by the cap body 401 and the claw tip 418.
[0022]
In this manner, the resin cap 400 covers the front locking portion 312 of the rubber grommet 300 and locks the panel 50 and the rubber grommet 300. Thereby, the resin cap 400 restricts the rubber grommet 300 from moving in the axial direction of the pipe 40, and prevents the rubber grommet 300 from coming off the panel 50. Further, the resin cap 400 covers the front locking portion 312 of the rubber grommet 300, and the claw 408 presses the through hole 351 from the outer peripheral direction, thereby suppressing the deformation of the soft rubber grommet 300 and causing the rubber grommet 300 to cut. To suppress opening. Since the groove 41 of the pipe 40 and the protrusion 355 of the rubber grommet 300 are fitted, the pipe 40 is fixed to the rubber grommet 300 and further to the panel 50.
[0023]
The grommet structure according to the second embodiment has the following advantages.
(1) The rubber grommet 300 can open and close the cutting line CL with the hinge 300H as a fulcrum. The resin cap 400 also has an opening 403. Thereby, even if both ends of the pipe are already connected to the device or the like, the rubber grommet 300 and the resin cap 400 can be attached to the pipe, and the pipe can be reliably fixed to the panel in a short time.
(2) The resin cap 400 sandwiches the panel 50 via the rear locking portion 311 and the front locking portion 312 of the rubber grommet 300 by the cap body 401 and the claw tip 418. Thereby, the adhesion between the resin cap 400 and the rubber grommet 300 is improved, and the vibration of the pipe is not easily transmitted to the vehicle body panel.
(3) In the resin cap 400, the trapezoidal convex portion 404 and the trapezoidal concave portion 405 are engaged with each other to maintain the circular shape of the cap body 401 and cover the front locking portion 312 of the rubber grommet 300. Thus, when the rubber grommet 300 is viewed from the front of the vehicle, the cut surface of the rubber grommet 300 is not visible, and the appearance is good.
(4) When fixing the pipe 40 to the panel 50, the groove 41 of the pipe 40 and the protrusion 355 of the rubber grommet 300 are fitted. This can prevent the rubber grommet 300 from being displaced from the pipe 40, thereby improving workability in the assembling process and preventing the fixed position from being displaced from the panel.
[0024]
――― Third embodiment ―――
Referring to FIG. 16, a third embodiment of the grommet structure according to the present invention will be described. The grommet structure of the third embodiment uses the grommet structure of the second embodiment to fix two pipes. Therefore, the differences between the grommet structure of the third embodiment and the grommet structure of the second embodiment will be mainly described.
[0025]
FIG. 16 is a diagram showing a state where two pipes are sandwiched between a rubber grommet and a resin cap. The grommet structure of the third embodiment is also composed of a rubber grommet and a resin cap similarly to the first and second embodiments, and the grommet structure of the second embodiment is vertically extended in two steps. It is a stacked structure. That is, the rubber grommet 500 has the upper through-hole 551 and the lower through-hole 552 that support two pipes provided through the opening of the vehicle body panel. The rubber grommet 500 includes a rear locking portion 511 having an elliptical bottom surface for fitting and locking the rubber grommet 500 into the panel opening, a disk-shaped upper front locking portion 512, and a lower portion. And a side front locking portion 513. The front locking portions 512 and 513 are provided in front of the rear locking portion 511, and when the rear locking portion 511 is fitted to the panel, the front locking portions 512 and 513 and the rear locking portion 511 are provided. Between the panel. When the rear locking portion 511 is viewed from the front, the rear locking portion 511 has the rear locking portion 511 at a position corresponding to the short axis of the ellipse symmetrically with respect to the long axis of the ellipse. Two through holes 507 are provided. A nail 608 of the resin cap 600 described later is fitted into the through hole 507. The rubber grommet 500 is cut along cutting lines CL1 and CL2 along the axial direction of the pipes 60 and 70, and can be mounted on the pipe by opening the hinge parts 500H and 500I in the direction of the arrow 5 as fulcrums. Protrusions (not shown) are provided on the inner peripheral surfaces of the through holes 551 and 552, respectively, similarly to the protuberances 355 in FIG. Similar to the groove 41 of the pipe 40 of the second embodiment, grooves (not shown) are provided in the pipes 60 and 70, and provided on the inner peripheral surfaces of the through holes 551 and 552 of the rubber grommet 500. And not shown protrusions.
[0026]
The resin cap 600 includes a cap body 601 having an elliptical cap shape with a low height. The cap body 601 is provided with two holes 602 and 603. Inside the cap body 601, two claws 608 are provided symmetrically with respect to the major axis of the ellipse at positions corresponding to the minor axis of the ellipse. The resin cap 600 has cut portions (openings) similar to the cut portions 403 shown in FIGS. 10A and 10B at the outer peripheral portions of the holes 602 and 603, respectively. The dovetail and the dovetail groove similar to the dovetail 404 and the dovetail groove 405 of FIG. 10B are provided in this opening, and when mounted on the rubber grommet 500, as in the second embodiment, The dovetail and the dovetail groove respectively fit.
[0027]
From the state of FIG. 16, the pipes 60 and 70 can be fixed to the panel by inserting the rubber grommet 500 into the opening of the panel and covering the rubber grommet 500 with the resin cap 600. The method for fixing the pipes 60 and 70 to the panel by using the rubber grommet 500 and the resin cap 600 is the same as that in the second embodiment, and a detailed description thereof will be omitted. The pipe diameters need not all be the same, and pipes having different diameters may be used.
[0028]
The grommet structure of the third embodiment has the following operation and effect in addition to the operation and effect of the second embodiment.
(1) The two pipes 60, 70 can be fixed to the panel by the rubber grommet 500 and the resin cap 600. Thereby, a plurality of pipes can be fixed simultaneously with a small number of parts, and the working time, the number of parts, and the cost in the assembly process can be reduced.
(2) Since pipes having different diameters can be fixed at the same time, the pipes can be reliably fixed to the panel with a small number of parts. Thereby, it is possible to cope with various pipe diameters with a simple structure, and cost can be reduced.
[0029]
――― Modifications ―――
The grommet structure of the second embodiment can be used to fix three or more pipes. For example, as shown in FIG. 17, three grommet structures according to the second embodiment are arranged vertically, and three pipes are formed by the same method as the grommet structure according to the third embodiment. It can also be fixed. In this case, if the rubber grommet 800 is provided with three through holes 821, 822, and 823, and is cut along a cutting line parallel to the axis of each of the through holes 821 to 823, the hinge can be opened and closed using the hinge as a fulcrum. Good. Then, three holes 921, 922, and 923 may be provided in the resin cap 900, and cut portions (openings) 903, 904, and 905 may be provided on the outer peripheral portions of the holes 921 to 923, respectively.
[0030]
In the above description, the pipe diameters need not all be the same, and pipes having different diameters may be used. By doing so, a plurality of pipes having different diameters can be fixed at the same time, so that the pipes can be reliably fixed to the panel with a small number of parts. As a result, it is possible to reduce the working time, the number of parts, and the cost in the assembly process. In the above description, the rubber grommet is made of soft rubber. However, any soft and elastic material capable of absorbing the vibration of the piping is not limited to soft rubber. For example, it may be something like a sponge. Further, when the pipe is sandwiched by the rubber grommet, the groove provided on the outer periphery of the pipe and the protrusion on the inner surface of the rubber grommet through-hole are fitted to regulate the movement in the axial direction. The shape of the joining portion is not limited to the above description. It may be a concave portion or a convex portion that is not a groove or a ridge, and the unevenness may be reversed from the above description. The fitting portion as the regulation structure may not be provided.
[0031]
In the above description, the object to be fixed was described as a pipe, but the present invention is not limited to this. For example, a wire harness may simply be bundled, a tape wound around the wire harness, or a resin tube on a spiral wound around a wire harness bundled. Also, a power supply cable or the like may be used, and the cross-sectional shape is not limited to a circle.
