Summary of the Invention

Problems to be Solved by the Invention

[0004] The grommets and wire harnesses described above have room for improvement in terms of increasing work efficiency during wire harness manufacturing. For example, when joining a grommet and the wire material inserted through the grommet at the tubular section during wire harness manufacturing, it is conceivable to integrate the tubular section and the wire material by wrapping tape around the tubular section and then wrapping tape around the wire material extending from the tubular section. In this case, if the tubular section is divided in the circumferential direction, it is necessary to support multiple tubular sections together at the center of the wire material side and wrap the tape around them. At this time, it is not easy to support multiple tubular sections together, which hinders the improvement of manufacturing efficiency.

[0005] Therefore, the present invention aims to provide grommets and wire harnesses that allow for efficient manufacturing while maintaining good die-cutting properties for the grommets. [Means for solving the problem]

[0006] In other words, the grommet according to the present invention comprises an annular water-stopping portion that is inserted into a through hole formed in a mounting panel to stop water, a closing portion formed that protrudes radially inward from the water-stopping portion and is provided on one side and the other side in the axial direction of the water-stopping portion, and a cylindrical portion provided in the center of the closing portion on one side and the other side through which a cable guide is inserted, and one of the closing portion and the cylindrical portion on either side has a plurality of divided portions that are divided circumferentially by a plurality of radially extending notches, and the plurality of divided portions are configured such that a connecting portion is formed in a part of the notches between adjacent divided portions in the cylindrical portion, and adjacent divided portions are connected by the connecting portion. [Effects of the Invention]

[0009] Embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited by these embodiments. Furthermore, some of the components in the following embodiments are substituted or substantially identical to those easily substituted by those skilled in the art.

[0010] [Embodiment] Figures 1 and 2 are perspective views of the grommet and wire harness according to this embodiment, and Figure 3 is a cross-sectional view of the grommet along line III-III in Figure 2. Figure 4 is a view of the grommet according to this embodiment from the axial direction. Figure 5 is an enlarged view of the grommet according to this embodiment and is an explanatory diagram of the cut portion, divided portion and connecting portion of the grommet. Figures 6 and 7 are explanatory diagrams of the manufacturing process of the wire harness according to this embodiment.

[0011] As shown in Figures 1, 2, and 3, the grommet 1 of this embodiment is incorporated into a wire harness WH routed in a vehicle or the like. Here, the wire harness WH is, for example, a bundle of multiple wiring materials W used for power supply and signal communication to connect various devices mounted on a vehicle, and the multiple wiring materials W are connected to each device with connectors or the like. The wire harness WH comprises conductive wiring materials W and a grommet 1 provided on the wiring materials W through which the wiring materials W are inserted. In addition, the wire harness WH may also include various components such as corrugated tubing, resin tape, protectors and other exterior members, electrical connection boxes, and fasteners. The wiring materials W are, for example, made of metal rods, electric wires, bundles of electric wires, etc. A metal rod is a conductive rod-shaped member with an insulating coating on the outside. An electric wire is a conductor (core wire) consisting of multiple conductive metal strands with an insulating coating on the outside. A wire bundle is a bundle of wires. A wire harness WH bundles and integrates multiple wiring members W, and various devices are electrically connected via connectors and the like provided at the ends of the bundled wiring members W.

[0012] The grommet 1 is applied to the through-hole 101 formed in the mounting panel 100, which is the object to be mounted, when routing the wiring material W across two spaces separated by the mounting panel 100. The mounting panel 100 is, for example, a metal plate that makes up the body of a vehicle, and the through-hole 101 penetrates the mounting panel 100 along the thickness direction. The two spaces separated by the mounting panel 100 are typically the interior space (e.g., the cabin) and the exterior space (e.g., the engine compartment). The grommet 1 is assembled into the through-hole 101 with the wiring material W of the wire harness WH inserted through it and the grommet 1 attached to the periphery of the wiring material W, thereby protecting the wiring material W passing through the through-hole 101 and sealing (waterproofing) the through-hole 101. In addition to waterproofing the through-hole 101, the grommet 1 also has functions such as dustproofing and sound insulation. The configuration of grommet 1 will be explained in detail below with reference to the respective figures.

[0013] In the drawings, the cable guide W and mounting panel 100 are sometimes omitted using dashed lines, or they are sometimes omitted altogether. In Figures 1 and 2, the mounting panel 100 is shown as a rectangle for illustrative purposes, but it is formed in a shape appropriate to the structure of the vehicle. In the following explanation, of the three intersecting directions, the first direction is referred to as the "axial direction X," the second direction as the "width direction Y," and the third direction as the "height direction Z." The axial direction X, width direction Y, and height direction Z are typically mutually orthogonal. Here, the axial direction X corresponds to the thickness direction of the mounting panel 100 described above, and corresponds to the insertion direction of the cable guide W and grommet 1 into the through hole 101. In other words, the axial direction X is the direction along the extension direction of the cable guide W inserted into the grommet 1. The width direction Y and the height direction Z correspond to the extending direction of the mounting panel 100. For the sake of clarity, this explanation assumes that the cable guide W is routed in a straight line along the axial direction X, but it is not limited to this. When the grommet 1 is attached to the mounting panel 100, the axial direction X may be a bent direction, and the grommet 1 and the cable guide W may be bent in part. Furthermore, unless otherwise specified, the directions used in the following explanation refer to the directions when the grommet 1 is assembled to the mounting panel 100. The central axis C passing through the center of the through hole 101 is perpendicular to the surface of the mounting panel 100 and extends along the axial direction X. The direction perpendicular to the central axis C is called the radial direction, the side away from the central axis C is called the radially outward direction, and the side approaching the central axis C is called the radially inward direction.

[0014] Specifically, as shown in Figures 1, 2, and 3, the grommet 1 of this embodiment is a sealing member that can seal off water between the grommet and the through hole 101 of the mounting panel 100, with a cable guide W inserted through it along the axial direction X. The grommet 1 is composed of a water-sealing portion 2, a closing portion 3, and a cylindrical portion 4, which are integrally formed as an elastic body. The grommet 1 is made of an insulating elastic resin material with low rigidity and high flexibility, such as rubber or thermoplastic elastomer (for example, ethylene-propylene-diene rubber (EPDM)).

[0015] The water-stopping section 2 is a portion that fits into the through hole 101 to stop water from entering the through hole 101, and through which the cable material W is inserted along the axial direction X. A closing section 3 and a cylindrical section 4 are provided on the radially inner side of the water-stopping section 2. The closing section 3 is formed by protruding radially inward from the water-stopping section 2 and has a first closing section 31 provided on one side of the water-stopping section 2 in the axial direction and a second closing section 32 provided on the other side in the axial direction. The cylindrical section 4 is a cylindrical portion provided in the center of the closing section 3 for inserting the cable material W. The cylindrical section 4 has a first cylindrical section 41 provided on one side of the water-stopping section 2 in the axial direction and a second cylindrical section 42 provided on the other side in the axial direction.

[0016] The first closing part 31 and the second closing part 32 are each formed in an annular plate shape with the central axis C along the axial direction X. The first closing part 31 and the second closing part 32 are spaced apart in the axial direction X and face each other on one side and the other side in the axial direction X and are integrated by the water stop part 2. Here, the water stop part 2 is an outer peripheral part provided annularly at an end portion located on the outer side in the radial direction (the direction orthogonal to the central axis C) in the first closing part 31 and the second closing part 32. The first closing part 31 and the second closing part 32 are respectively disposed on one side and the other side in the axial direction X of the water stop part 2 so as to protrude inside the radial direction of the water stop part 2 and close the annulus of the water stop part 2. At least one of the first closing part 31 and the second closing part 32 (here, the second closing part 32) is formed in a shape bulging outward along the axial direction X. The first closing part 31 and the second closing part 32 are integrally formed by the water stop part 2 and are formed in a dome shape with a hollow interior as a whole. The first cylinder part 41 is connected to a surface of the first closing part 31 on the side opposite to the second closing part 32 side in the axial direction X. The second cylinder part 42 is connected to a surface of the second closing part 32 on the side opposite to the first closing part 31 side in the axial direction X.

[0017] Here, a protrusion part 321 protruding outward (on the side opposite to the first closing part 31 in the axial direction X) is formed on the second closing part 32. The protrusion part 321 has an annular protrusion part 321A formed annularly around the central axis C so as to surround the base end part of the second cylinder part 42, and a plurality of radially protruding protrusion parts 321B provided radially outward from the annular protrusion part 321A and located radially around the central axis C. In this embodiment, the radially protruding protrusion parts 321B are located at eight positions at equal intervals in the circumferential direction. Such a protrusion part 321 improves the strength of the second closing part 32 and suppresses deformation.

[0018] The water stop part 2 is formed so as to integrate the first closing part 31 and the second closing part 32 therebetween. The water stop part 2 is formed radially outward from a position where the wall thickness changes with respect to the first closing part 31. The water stop part 2 has a fitting groove part 21 and a lip part 22. The fitting groove part 21 is formed as an annular groove part centered on the central axis C. The fitting groove part 21 is fitted with an edge part forming the through hole 101 in the mounting panel 100 in a state where the main body part 10 is fitted into the through hole 101.

[0019] The lip portion 22 is a fold-like portion formed along the fitting groove portion 21. Here, the lip portion 22 is formed annularly along the fitting groove portion 21 at the end portion on the side of the first closing portion 31 in the fitting groove portion 21. That is, the lip portion 22 is formed annularly around the central axis C in the fitting groove portion 21. The lip portion 22 contacts the surface of the edge portion (here, the surface on the side of the first closing portion 31) in a state where the edge portion of the through hole 101 is fitted into the fitting groove portion 21 and seals the space between the lip portion 22 and the surface. The lip portion 22 is configured to closely adhere to the surface of the edge portion forming the through hole 101 by elastic deformation and seal the entire peripheral edge of the through hole 101.

[0020] The first cylindrical portion 41 and the second cylindrical portion 42 are integrally formed with the main body portion 10 in a cylindrical shape and are portions through which the wire harness W is inserted along the axial direction X inside.

[0021] The first cylindrical portion 41 is formed so as to project from the first closing portion 31 along the axial direction X to the other side (the side opposite to the second closing portion 32). The first cylindrical portion 41 is formed in a cylindrical shape centered on the central axis C and extends along the axial direction X. The first cylindrical portion 41 is formed in a cylindrical shape with a smaller diameter than the first closing portion 31. The tip end portion on the other side in the axial direction X of the first cylindrical portion 41 is open, and the base end portion on one side is connected to the first closing portion 31. The first cylindrical portion 41 penetrates and is connected to a substantially central position of the first closing portion 31 with respect to the width direction Y and the height direction Z. Here, the base end portion of the first cylindrical portion 41 on the side of the first closing portion 31 in the axial direction X is formed such that the diameter increases as it approaches the first closing portion 31. A plurality of lip portions 41A are formed on the inner peripheral surface of the first cylindrical portion 41. The plurality of lip portions 41A are each a fold-like water stop portion formed annularly along the circumferential direction (the direction around the central axis C) and are spaced apart along the axial direction X. Each lip portion 41A contacts the outer surface of the wire harness W in a state where the wire harness W is inserted inside and seals the space between the lip portion 41A and the outer surface. Each lip portion 41A is configured to closely adhere to the outer surface of the wire harness W by elastic deformation and seal the entire circumference of the wire harness W.

[0022] The second cylindrical portion 42 is formed to protrude from the second closing portion 32 in the axial direction X to one side (opposite to the first closing portion 31). The second cylindrical portion 42 is formed in a cylindrical shape with a central axis C and extends along the axial direction X. The second cylindrical portion 42 is formed in a cylindrical shape with a smaller diameter than the second closing portion 32. The tip of the second cylindrical portion 42 on one side in the axial direction X is open, and the base end on the other side penetrates and connects to the second closing portion 32. The second cylindrical portion 42 is connected to the approximate center position of the second closing portion 32 with respect to the width direction Y and the height direction Z. Here, the second cylindrical portion 42 is formed such that the diameter increases as the base end on the second closing portion 32 side in the axial direction X approaches the second closing portion 32.

[0023] In the grommet 1, the internal spaces of the watertight section 2, the first closing section 31, the second closing section 32, the first cylindrical section 41, and the second cylindrical section 42 function as an insertion space 11. The insertion space 11 is a space through which the cable material W is inserted, and it is continuous along the axial direction X across the first cylindrical section 41, the watertight section 2, and the second cylindrical section 42. In the grommet 1, the cable material W is inserted along the axial direction X into the insertion space 11 which is formed by communication across the first cylindrical section 41, the watertight section 2, and the second cylindrical section 42.

[0024] The grommet 1 is attached to the cable material W by inserting it into the insertion space 11, and then the first cylindrical portion 41 or the second cylindrical portion 42 is inserted into the through hole 101 together with the end of the cable material W. The grommet 1 is then assembled to the mounting panel 100 by fitting the water-sealing portion 2 into the through hole 101 so that the edge of the through hole 101 fits into the water-sealing portion 2. In this state, the lip portion 22 of the grommet 1 elastically deforms and adheres tightly to the surface of the periphery of the through hole 101, sealing the entire periphery of the through hole 101. Alternatively, the grommet 1 may be fitted with a winding tape or the like wrapped around the cable material W inserted into the insertion space 11, the first cylindrical portion 41 and the second cylindrical portion 42, and the cable material W to seal the openings of the first cylindrical portion 41 and the second cylindrical portion 42.

[0025] In this manner, the grommet 1 and wire harness WH seal the through-hole 101 formed in the mounting panel 100 by fitting the watertight portion 2 into the through-hole 101, while the wiring material W is inserted inside.

[0026] As shown in Figures 4 and 5, the second closing portion 32 and the second cylindrical portion 42 have multiple divisions 6 that are divided circumferentially by multiple radially extending notches 5. The notches 5 are slits formed radially from the central axis C in the second closing portion 32 and the second cylindrical portion 42. The notches 5 penetrate both the front and back surfaces of the second closing portion 32 and the second cylindrical portion 42 and extend from the second cylindrical portion 42 to the position of the water-stopping portion 2. For example, four of these notches 5 are formed at equal intervals in the circumferential direction, dividing the second closing portion 32 and the second cylindrical portion 42 into four divisions 6. The division of the second closing portion 32 and the second cylindrical portion 42 improves the demolding performance during the molding of the grommet 1. That is, when demolding is performed, the second closing portion 32 and the second cylindrical portion 42 can be opened radially outward, and the core portion of the mold for forming the insertion space 11 can be smoothly withdrawn.

[0027] Multiple divisions 6 form connecting portions 7 in a part of the notch 5 between adjacent divisions 6 in the second cylindrical portion 42. The connecting portions 7 are formed on a part of the notch 5 between adjacent divisions 6, and connect adjacent divisions 6. Divisions 6 on which the connecting portions 7 are formed are integrated through the connecting portions 7. In Figure 4, connecting portions 7 are formed on two of the four notches 5 that are opposite each other across the axis (central axis C) of the water-stopping portion 2. The connecting portions 7 are formed, for example, at the tip of the second cylindrical portion 42. In other words, the connecting portions 7 connect adjacent divisions 6 at the tip of the second cylindrical portion 42. Here, the tip of the second cylindrical portion 42 may be the very tip of the second cylindrical portion 42, or it may be a position closer to the tip than the center of the axial direction X of the second cylindrical portion 42. Figure 5 shows the case where the connecting portion 7 is formed at the very tip of the second cylindrical portion 42. The connecting portion 7 connects the divided portion 6, making it easier to bundle the divided second cylindrical portion 42 toward the central side where the cable material W is located during manufacturing. The notch portion 5 is formed between the adjacent divided portions 6 where the connecting portion 7 is formed, from the second closing portion 32 to the position of the connecting portion 7 in the second cylindrical portion 42. Even if the connecting portion 7 is formed in part of the notch portion 5, the mold release properties during molding of the grommet 1 will be good. That is, the second closing portion 32 and the second cylindrical portion 42 are divided circumferentially by a plurality of notches 5 extending radially, and the notches 5 connected by the connecting portion 7 are a part of them, so the core portion of the mold for forming the insertion space portion 11 can be smoothly pulled out by opening the second closing portion 32 and the second cylindrical portion 42 radially outward.

[0028] Next, a method for joining the grommet 1 and a method for manufacturing the wire harness WH according to this embodiment will be described.

[0029] As shown in Figure 6, the wiring material W is inserted through the grommet 1, and the wiring material W and grommet 1 are joined together to manufacture the wire harness WH. For example, tape T is used to join the wiring material W and grommet 1. Tape T is wound around the second cylindrical portion 42 of the grommet 1, and tape T is also wound around the wiring material W extending from the second cylindrical portion 42, so that the second cylindrical portion 42 and the wiring material W are integrated by tape T.

[0030] In this manufacturing process, in order to wrap the tape T around the second cylindrical section 42 and the wiring harness W, it is necessary to bundle the divided second cylindrical section 42 towards the central position where the wiring harness W is located. At this time, as shown in Figure 7, since a part of the divided section 6 of the second cylindrical section 42 is connected by a connecting section 7, it can be easily bundled toward the wiring harness W. For example, if four divided sections 6 are joined by two connecting sections 7 to form two divided bodies, the two divided bodies (four divided sections 6) can be easily bundled toward the wiring harness W with one hand. In other words, it becomes possible to pull and bundle the four divided sections 6 toward the wiring harness W with one hand and wrap the tape T with the other hand, allowing the joining work between the wiring harness W and the grommet 1 and the manufacturing work of the wire harness WH to be carried out efficiently.

[0031] Here, if the second cylindrical section 42 were not provided with a connecting section 7, the four divided sections 6 would need to be bundled together on the cable material W side, but this would be difficult to do with one hand. In other words, it would be difficult to pull the four divided sections 6 towards the cable material W side with one hand, and it would be necessary to use both hands to pull the four divided sections 6 towards the cable material W side and bundle them together. Then, the bundled divided sections 6 would be held in one hand for support, and the tape T would be wrapped around them to perform the joining work. In other words, compared to the grommet 1 and wire harness WH according to this embodiment, the number of work steps would increase, and the joining work between the cable material W and the grommet 1 and the manufacturing work of the wire harness WH would not be performed efficiently. Dividing the closing section 3 and cylindrical section 4 in this way improves the ease of demolding during molding, but it makes the manufacturing work less efficient. In contrast, the grommet 1 and wire harness WH according to this embodiment connect the divided sections 6 with a connecting section 7, thereby improving the ease of demolding during molding while enabling efficient manufacturing.

[0032] As described above, according to the grommet 1 and wire harness HW of this embodiment, the second closing portion 32 and the second cylindrical portion 42 are divided in the circumferential direction, making it easier to demold the grommet 1 during molding. Furthermore, since a portion of the divided divided portions 6 is connected by the connecting portion 7, it is easy to join the divided second cylindrical portion 42 to the wiring material W. For this reason, the grommet 1 and wire harness HW can be manufactured efficiently while maintaining good demoldability of the grommet 1.

[0033] Furthermore, in this embodiment, the grommet 1 and wire harness HW have a connecting portion 7 formed at the tip of the second cylindrical portion 42, which allows the divided tips of the second cylindrical portion 42 to be easily bundled together during wiring, enabling efficient manufacturing.

[0034] Furthermore, the grommet 1 and wire harness HW according to this embodiment are formed by connecting four divided sections 6 with two connecting sections 7 to form two divided bodies. Therefore, the divided sections 6 can be pulled together and bundled with one hand during wiring, making the manufacturing process easier.

[0035] It should be noted that the grommet 1 and wire harness WH according to the embodiments of the present invention described above are not limited to the embodiments described above, and various modifications are possible within the scope of the claims. Furthermore, the grommet 1 and wire harness WH according to this embodiment may be constructed by appropriately combining the components of the embodiments and modified examples described above.

[0036] In the embodiment described above, the case in which the second closing portion 32 and the second cylindrical portion 42 are divided into four parts was explained, but the second closing portion 32 and the second cylindrical portion 42 may be divided into three or four or more parts. Even in this case, the same effects and advantages as in the embodiment described above can be obtained by connecting the divided parts 6 with the connecting parts 7. [Explanation of Symbols]
