Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1 above, when inserting the wire harness into the panel hole, first, the wire harness is inserted into the grommet and the grommet is attached to the wire harness. Then, the portion from the tip of the wire harness to the portion where the grommet is attached is passed inside the panel hole, and then the grommet is attached to the panel hole.

[0005] In such an insertion operation of the wire harness, it is necessary to perform the operation so that the wire harness and the panel do not come into contact with each other and the wire harness is not damaged, and there is a problem that the insertion operation becomes complicated.

[0006] The problem to be solved by the present invention is to provide a panel assembly and a grommet capable of improving the efficiency of the assembly work of a linear member and a grommet to a panel.

Brief Description of the Drawings

[0020] [Figure 1] FIG. 1 is a perspective view showing a panel assembly according to an embodiment of the present invention. [Figure 2] FIG. 2 is an exploded perspective view showing a panel assembly according to an embodiment of the present invention. [Figure 3] FIG. 3(a) is a first perspective view of a grommet according to an embodiment of the present invention, and FIG. 3(b) is a second perspective view of the grommet according to an embodiment of the present invention. [Figure 4] ​​​​​​​​​​​​​​​​​​​​​​​​​​​​As shown in Figures 1 and 2, the panel assembly 1 in this embodiment comprises a wire 10, a panel 20, and a grommet 30. The wire 10 is one of several wires included in a wire harness. This wire harness is a component comprising several wires and connectors (not shown) attached to the wires. The wire 10 is used to transmit electrical signals to the vehicle's electrical components. In this embodiment, the wire 10 is routed to pass through the panel 20.

[0024] This electric wire 10 corresponds to an example of a "linear member" in an embodiment of the present invention. Note that the "linear member" in an embodiment of the present invention may be any linear component and is not limited to electric wires of a wire harness. While not particularly limited, this "linear member" may, for example, be a cable that transmits optical signals, and in this case, the cable may include an optical fiber cable.

[0025] Panel 20 is, for example, a metal plate-like member that constitutes part of the vehicle body, and is a partition wall that separates multiple internal spaces of the vehicle. Panel 20 is not particularly limited, but could be a door panel, a dashboard panel, etc. However, panel 20 may also be a panel included in machinery other than a vehicle.

[0026] As shown in Figure 2, the panel 20 comprises a plate-like portion 21, mounting holes 22, and slits 23. The plate-like portion 21 has a polygonal planar shape. The plate-like portion 21 in this embodiment is not particularly limited, but has a substantially rectangular planar shape defined by four straight edges 21a, 21b, 21c, and 21d.

[0027] In this embodiment, the plate-like portion 21 does not have bent or curved portions and is composed only of a single flat portion, but is not limited to this. Depending on the structure of the vehicle, the plate-like portion 21 may have bent or curved portions as appropriate.

[0028] A mounting hole 22 is formed in the plate-shaped portion 21. This mounting hole 22 penetrates the plate-shaped portion 21 in the direction of its thickness. The electric wire 10 is inserted through this mounting hole 22 and fixed to the plate-shaped portion 21 via the grommet 30. Specifically, the mounting hole 22 is a through-hole into which the main body portion 40 (described later) of the grommet 30 is fitted, and has a shape substantially identical to the outer shape of the main body portion 40 of the grommet 30.

[0029] The outer shape of the mounting hole 22 in this embodiment is not particularly limited, but is oval (track-shaped, or oval-shaped). Here, oval shape means a shape consisting of a pair of straight sections 22a and 22b extending parallel to each other, and a pair of arc sections 22c and 22d connecting the straight sections to each other. The outer shape of the mounting hole 22 may also be a perfect circle, an ellipse, a polygon, or the like.

[0030] A slit 23 is formed in the plate-like portion 21. The slit 23 is a through-hole into which the protruding portion 70 (described later) of the grommet 30 is fitted, and it has a strip shape. This slit 23 penetrates the plate-like portion 21 in the direction of its thickness. The slit 23 is connected to the fitting hole 22 and also opens to the edge 21a of the plate-like portion 21. Specifically, the upper end 23a of the slit 23 (one end in the +Z direction) is connected to the straight portion 22b of the fitting hole 22. On the other hand, the lower end 23b of the slit 23 (the other end in the -Z direction) opens to the edge 21a of the plate-like portion 21. Therefore, the slit 23 extends vertically downward (in the -Z direction in the figure) from the straight portion 22b of the fitting hole 22 to the edge 21a of the plate-like portion 21.

[0031] As described above, the slit 23 extends vertically downward, allowing the second grooves 701a and 701b (described later) of the protruding portion 70 (described later) of the grommet 30 to open vertically downward. This makes it difficult for water to penetrate the second grooves 701a and 701b (described later), thereby improving the waterproofing performance of the grommet 30.

[0032] As shown in Figures 1 and 2, the grommet 30 is fitted into the mounting holes 22 and slits 23 of the panel 20 for the protection of the electric wires 10 and for waterproofing the interior space of the vehicle. The material constituting the grommet 30 is not particularly limited, but examples include rubber and flexible plastic.

[0033] Figure 3(a) is a first perspective view of the grommet 30 in this embodiment, and Figure 3(b) is a second perspective view of the grommet 30 in this embodiment. Figure 4 is a rear view showing the grommet 30 in this embodiment. Figure 5 is a cross-sectional view showing the grommet 30 cut along the VV line in Figure 3(a). Figure 6 is a bottom view showing the grommet 30 in this embodiment. Note that the first perspective view shown in Figure 3(a) is a perspective view of the grommet 30 shown in Figures 1 and 2, inverted in the vertical direction (±Z direction). The second perspective view shown in Figure 3(b) is a perspective view of the grommet 30 shown in Figure 3(a), inverted in the front-back direction (±Y direction).

[0034] As shown in Figure 3(a), the grommet 30 comprises a main body portion 40 and a protruding portion 70. In this embodiment, the main body portion 40 is integrally formed with the protruding portion 70. The main body portion 40 is the part that is fitted into the mounting hole 22. This main body portion 40 comprises a base portion 50 and a cylindrical portion 60.

[0035] As shown in Figures 1 and 2, the base portion 50 is the part that is fitted into the mounting hole 22. As shown in Figures 3(b) and 5, this base portion 50 has a bottomed cylindrical shape. As shown in Figure 4, when the base portion 50 is viewed along the Y direction (when the base portion 50 is viewed from the front along the +Y direction, or when the base portion 50 is viewed from the back along the -Y direction), the base portion 50 has an oval shape. That is, when the base portion 50 is viewed along the Y direction, the contour of the base portion 50 is composed of a pair of straight sections 50a, 50b that extend parallel to each other, and a pair of arc sections 50c, 50d that connect the pair of straight sections 50a, 50b to each other. Note that the contour of the base portion 50 refers to the shape of the outer edge of the base portion 50 when the base portion 50 is viewed along the Y direction. Furthermore, in this case, the straight section 50b in this embodiment is a straight section that constitutes the boundary line with the protruding section 70 (corresponding to the dashed line in Figure 4).

[0036] As shown in Figures 3(b), 4, and 5, the base portion 50 includes a first recess 501. This first recess 501 is formed on the rear surface 50e of the base portion 50 and is a bottomed recess that is recessed in the -Y direction in the figures. As shown in Figure 4, when the first recess 501 is viewed along the -Y direction, the first recess 501 has an oval shape similar to the outer shape of the base portion 50, although it is not particularly limited. This first recess 501 reduces the rigidity of the base portion 50, making it easier to install the base portion 50 into the mounting hole 22. This improves the efficiency of the assembly work of the panel assembly 1. The -Y direction in the figures corresponds to an example of the "first direction" in the embodiment of the present invention.

[0037] As shown in Figures 3(a) and 5, the base portion 50 comprises a large-diameter portion 51, a first tapered portion 52, a first seal lip portion 53, and a holding portion 54. The large-diameter portion 51, the first tapered portion 52, the first seal lip portion 53, and the holding portion 54 are integrally formed. Furthermore, as shown in Figure 5, the large-diameter portion 51, the first tapered portion 52, and the holding portion 54 are arranged in this order along the first central axis CA1 of the first recess 501, and the central axis of the large-diameter portion 51, the central axis of the first tapered portion 52, and the central axis of the holding portion 54 substantially coincide with the first central axis CA1.

[0038] The large-diameter portion 51 has a cylindrical shape. This large-diameter portion 51 is located at the rear end (the end in the +Y direction) of the base portion 50. This large-diameter portion 51 has the largest outer diameter within the base portion 50. Therefore, when the base portion 50 is viewed along the Y direction, the outer circumferential surface of this large-diameter portion 51 defines the outer shape of the base portion 50.

[0039] Furthermore, this large-diameter portion 51 has an outer diameter larger than the diameter of the mounting hole 22 of the panel 20 (see Figure 2). For this reason, the large-diameter portion 51 is not inserted through the mounting hole 22, but is positioned to face the main surface of the plate-like portion 21 of the panel 20.

[0040] As shown in Figure 5, the first tapered portion 52 has a cylindrical shape. The rear end (the end in the +Y direction) of this first tapered portion 52 is connected to the large diameter portion 51. The first recess 501 described above is formed in the large diameter portion 51 and the first tapered portion 52, and opens to the outside of the grommet 30 at the rear end (the end in the +Y direction) of the large diameter portion 51.

[0041] The first tapered portion 52 includes a first tapered surface 52a. This first tapered surface 52a is inclined to approach the first central axis CA1 as it moves away from the large diameter portion 51. The first tapered portion 52 is the part that is inserted into the mounting hole 22. Therefore, this first tapered surface 52a allows the first tapered portion 52 to be easily inserted into the mounting hole 22.

[0042] As shown in Figures 3(a) and 5, a first groove 502 is formed between the large-diameter portion 51 and the first tapered portion 52. This first groove 502 is formed on the outer circumferential surface 50f of the base portion 50 and extends in the circumferential direction of the base portion 50. Specifically, in this embodiment, the first groove 502 extends along the straight portion 50a and the arc portions 50c and 50d of the base portion 50. In this first groove 502, the outer diameter of the base portion 50 is the same as the diameter of the mounting hole 22 of the panel 20, and the first groove 502 is fitted into the mounting hole 22.

[0043] The first seal lip portion 53 protrudes from the outermost circumference of the first groove 502 in the -Y direction. This first seal lip portion 53 extends along the first groove 502. By contacting the main surface of the panel 20 (see Figures 1 and 2), this first seal lip portion 53 seals the first groove 502 from the outside of the grommet 30, thereby preventing water from entering the first groove 502.

[0044] As shown in Figures 3(a) and 5, the retaining portion 54 holds the cylindrical portion 60 and has an annular shape. The retaining portion 54 is located inside the first tapered portion 52 and outside the cylindrical portion 60. As shown in Figure 5, this retaining portion 54 constitutes the bottom of the first recess 501.

[0045] The holding portion 54 has a thick portion 541 and a thin portion 542. The thick portion 541 is located inside the first tapered portion 52 and is connected to the first tapered portion 52. The thin portion 542 has an annular shape. This thin portion 542 is located inside the thick portion 541 and is connected to the thick portion 541. The thickness of the thin portion 542 is thinner than the thickness of the thick portion 541, and as a result, the rigidity of the thin portion 542 is less than that of the thick portion 541. Therefore, the thin portion 542 can hold the cylindrical portion 60 in a tiltable manner. That is, the thin portion 542 is easily elastically deformable, and as a result, the cylindrical portion 60 can tilt relative to the first central axis CA1 of the first recess in response to the load applied from the electric wire 10.

[0046] The cylindrical portion 60 is held by the holding portion 54 so as to protrude from the base portion 50 in the -Y direction. In this embodiment, the cylindrical portion 60 has a cylindrical shape extending along the Y direction and has a through hole 61 inside. As shown in Figures 1, 2, and 5, the electric wire 10 is inserted through this through hole 61. The cylindrical portion 60 may also have an elliptical or rectangular shape.

[0047] As shown in Figures 3(b), 4, and 5, the rear end 60a of the cylindrical portion 60 is located inside the first recess 501, and the cylindrical portion 60 opens into the first recess 501. Therefore, as shown in Figure 4, when the main body portion 40 is viewed along the -Y direction, the through hole 61 is located inside the first recess 501. In the grommet 30 of this embodiment, the electric wire 10 is inserted not only inside the through hole 61 but also inside the first recess 501.

[0048] As shown in Figures 4 and 5, when the main body 40 is viewed along the -Y direction, the second central axis CA2 of the through hole 61 is located closer to the protrusion 70 than the first central axis CA1 of the first recess 501. As shown in Figure 4, since the grommet 30 in this embodiment has a protrusion 70, the center of gravity G of the grommet 30 is eccentric from the center of the first recess 501 toward the protrusion 70. When the grommet 30 is installed in the mounting hole 22 of the panel 20, the grommet 30 deforms around the center of gravity G, so the worker can easily deform the grommet 30 to fit the mounting hole 22 by holding the cylindrical part 60 of the grommet 30 and inserting it into the mounting hole 22. This improves the efficiency of the assembly work of the panel assembly 1. In this embodiment, the first central axis CA1 coincides with the center of gravity G of the grommet 30, but is not limited to this, and may be slightly offset from the center of gravity G.

[0049] Furthermore, as shown in Figures 3(a) and 5, the cylindrical portion 60 has a pair of notches 62, 62. These notches 62 are located at the tip 60b of the cylindrical portion 60 and extend along the Y direction. The notches 62 make it easier to deform the tip 60b of the cylindrical portion 60. Although not particularly limited, the tip 60b may be narrowed by wrapping a tape member 80 around it, and then the tip 60b may be fixed to the electric wire 10 with the tape member 80. In this case, the notches 62 make it easier to deform the tip 60b. Therefore, the efficiency of the assembly work of the panel assembly 1 can be improved.

[0050] As shown in Figures 1 and 2, the protruding portion 70 is the part that fits into the slit 23, and in this embodiment, it has a prism shape that protrudes from the base portion 50 in the vertical downward direction (-Z direction). In this embodiment, the protruding portion 70 does not extend to the edge 21a of the panel 20, and a part of the slit 23 is exposed from the protruding portion 70. However, the protruding portion 70 may extend to the edge 21a of the panel 20, or the protruding portion 70 may fit into the entire slit 23. Furthermore, the protruding portion 70 only needs to protrude in the radial direction of the cylindrical portion 60, and may protrude in a radial direction other than the vertical downward direction.

[0051] As shown in Figures 3(a), 3(b), 4, and 6, the projection 70 includes a wide portion 71, a second tapered portion 72, and a second seal lip portion 73. The wide portion 71, the second tapered portion 72, and the second seal lip portion 73 are integrally formed.

[0052] The wide portion 71 is connected to the large-diameter portion 51 and protrudes vertically downward from the large-diameter portion 51. This wide portion 71 has a rectangular cross-sectional shape. This wide portion 71 has a width greater than the width of the slit 23 of the panel 20 (see Figures 1 and 2). Therefore, the wide portion 71 is not inserted through the slit 23 and is positioned to face the main surface of the plate-like portion 21 of the panel 20.

[0053] A second recess 711 is formed on the rear surface 71a of the wide portion 71. As shown in Figures 3(a), 4, and 6, the second recess 711 is connected to the first recess 501 of the base portion 50. This second recess 711 extends vertically downward from the lower end of the first recess 501 to the bottom surface 71b of the wide portion 71. This second recess 711 reduces the rigidity of the protruding portion 70, making it easier to attach the protruding portion 70 to the slit 23 (see Figures 1 and 2). This improves the efficiency of the assembly of the panel assembly 1.

[0054] The second tapered portion 72 has a trapezoidal cross-sectional shape. One end of the second tapered portion 72 is connected to the wide portion 71. The second tapered portion 72 includes a pair of second tapered surfaces 72a. The pair of second tapered surfaces 72a are inclined to move closer to each other as they move away from the wide portion 71. These second tapered surfaces 72a allow the projection 70 to be easily inserted into the slit 23 (see Figures 1 and 2).

[0055] As shown in Figures 3(a), 3(b), and 6, a pair of second grooves 701a and 701b are formed between the wide portion 71 and the second tapered portion 72. The second groove 701a is formed on the side surface 70a of the protruding portion 70 and extends vertically downward. Similarly, the second groove 701a is formed on the side surface 70b opposite to the side surface 70a and extends along the Z direction. The second groove 701a is connected to one end of the first groove 502, and the second groove 701b is connected to the other end of the first groove 502. The width between the second grooves 701a and 701b is the same as the width of the slit 23 (see Figures 1 and 2), and the second grooves 701a and 701b are fitted into the slit 23.

[0056] A pair of second seal lip portions 73 are formed in a pair of second grooves 701a and 701b, respectively. These second seal lip portions 73 protrude from the second grooves 701a and 701b in the -Y direction. Furthermore, these pair of second seal lip portions 73 extend along the second grooves 701a and 701b, that is, they extend along the Z direction. One end of one second seal lip portion 73 is connected to one end of the first seal lip portion 53, and the other end of the second seal lip portion 73 is connected to the other end of the first seal lip portion 53. These second seal lip portions 73, like the first seal lip portion 53, abut against the main surface of the panel 20, thereby sealing the second grooves 701a and 701b from the outside of the grommet 30 and preventing water from entering the second grooves 701a and 701b.

[0057] As shown in Figure 6, the width Wp of the protrusion 70 is greater than the diameter dc of the cylindrical portion 60. That is, the width Wp of the protrusion 70 is greater than the diameter of the through hole 61. Similarly, the width Ws of the slit 23 (see Figure 2) into which the protrusion 70 is mounted is also greater than the diameter dc of the cylindrical portion 60. That is, the width Ws of the slit 23 is greater than the diameter of the through hole 61. In this way, because the widths of the protrusion 70 and the slit 23 are greater than the width of the cylindrical portion 60, the cylindrical portion 60 can be passed through the slit 23 in the panel assembly method described later, thereby improving the efficiency of the panel assembly work.

[0058] Next, the assembly method of the panel assembly 1 described above will be explained with reference to Figures 7(a) to 7(c). Figures 7(a) to 7(c) are cross-sectional views illustrating the assembly method of the panel assembly 1 in this embodiment. Figure 7(a) is a cross-sectional view showing the first mounting process, Figure 7(b) is a cross-sectional view showing the insertion process, and Figure 7(c) is a cross-sectional view showing the second mounting process.

[0059] First, as shown in Figure 7(a), before attaching the grommet 30 to the panel 20, the electric wire 10 is inserted through the through hole 61 and the first recess 501 of the grommet 30. Then, the grommet 30 is fixed to a predetermined portion of the electric wire 10. At this time, the grommet 30 may also be fixed to the electric wire 10 by wrapping the tape member 80 around the outer surface of the cylindrical portion 60 and the outer surface of the electric wire 10. In this way, the first attachment step of attaching the grommet 30 to the electric wire 10 is completed.

[0060] Next, as shown in Figure 7(b), the electric wire 10 and the cylindrical portion 60 of the grommet 30 are inserted into the slit 23 from the edge 21a side of the panel 20, passed through the slit 23, and entered into the mounting hole 22. In this way, the insertion process of inserting the electric wire 10 and the cylindrical portion 60 of the grommet 30 into the mounting hole 22 is completed. In this example, the portion of the electric wire 10 surrounded by the cylindrical portion 60, and the cylindrical portion 60 itself, are inserted into the slit 23 and the mounting hole 22, but this is not limited to this. The portion of the electric wire 10 that is not inserted into the grommet 30 may also be inserted into the slit 23 and the mounting hole 22.

[0061] Next, as shown in Figure 7(c), the grommet 30 is pulled in the -Y direction, deforming the base portion 50 and the protruding portion 70, while engaging the first groove 502 of the base portion 50 with the mounting hole 22, and engaging the second grooves 701a, 701b of the protruding portion 70 (see Figures 3(a), 3(b), and 6) with the slit 23. In this way, the second mounting step of attaching the grommet 30 to the panel 20 is completed. The assembly method of the panel assembly 1 in this embodiment is thus completed.

[0062] In conventional panel assemblies, inserting electric wires into mounting holes requires a pulling operation where the wires are pulled along their direction of extension while being guided into the mounting holes. In contrast, with the panel assembly 1 of this embodiment, the grommet 30 can be easily attached to the mounting hole 22 via the slit 23. Therefore, the efficiency of the assembly work of the panel assembly 1 can be improved.

[0063] Furthermore, in conventional wiring operations, the wires are prone to coming into contact with the panels, requiring the wrapping of protective material around the wires to prevent damage. Additionally, this protective material must be removed after the wires have been inserted. In contrast, this embodiment eliminates the need for this wiring operation, thus eliminating the need for wrapping and removing protective material, thereby improving the efficiency of the panel assembly 1.

[0064] The embodiments described above are provided to facilitate understanding of the present invention and are not intended to limit it. Therefore, each element disclosed in the above embodiments is intended to include all design modifications and equivalents that fall within the technical scope of the present invention.

[0065] For example, in the above embodiment, the extension direction of the slit 23 is vertically downward, but it is not limited to this. The extension direction of the slit 23 does not have to be parallel to the vertically downward direction. Figure 8 is a front view showing a modified example of the panel assembly 1 in this embodiment.

[0066] As shown in Figure 8, in this modified example, the panel assembly 1 is positioned on the vehicle so as to be inclined with respect to the horizontal plane. In this case, the angle θ between the extending direction of the slit 23 and the vertical downward direction is greater than 0° (θ>0°). This angle θ is not particularly limited, but it is preferably 80° or less (θ≦80°). Good waterproofing can be obtained if the slit 23 extends such that the angle θ is 80° or less.
