Description

TECHNICAL FIELD The present invention relates to a grommet for closing an electric wire through hole of a vehicle body panel through which an electric wire penetrates and a wire harness having a grommet.

Conventionally, various grommets have been proposed (for example, Patent Document 1). As a conventional example of such a grommet, there is one shown in FIGS. 13 to 16, an electric wire through hole 2 is formed in the vehicle body panel 1. The electric wire W passes through the electric wire through hole 2. A grommet 100 is attached to the outer circumference of the electric wire W. The grommet 100 includes a grommet body 101 made of a flexible material (for example, a rubber material), and an inner protector 110 arranged inside the grommet body 101 and made of a material having higher rigidity than the grommet body 101. ..

A lip portion 102 is formed on the grommet body 101 on the contact surface side of the vehicle body panel 1. The inner protector 110 is provided with a plurality of panel locking claws 111 at intervals in the circumferential direction. The grommet 100 is attached to the vehicle body panel 1 by sandwiching the outer peripheral edge of the wire through hole 2 of the vehicle body panel 1 by the panel locking claw 111 and the lip portion 102. The lip portion 102 is brought into close contact with the outer peripheral edge of the wire through hole 2 of the vehicle body panel 1 by the clamping force of the panel locking claw 111 and the lip portion 102 on the vehicle body panel 1.

On the grommet body 101, an electric wire holding cylinder portion 103 is formed on the side opposite to the contact surface of the vehicle body panel 1. The electric wire holding cylinder portion 103 and the portion of the electric wire W pulled out from the electric wire holding cylindrical portion 103 are wound with a tape T. The inner surface of the wire holding tubular portion 103 is in close contact with the outer circumference of the wire W.

In this way, the grommet 100 mounted from one side of the vehicle body panel 1 has the wire through hole 2 for routing the electric wire W across the space 3 on one side of the vehicle body panel 1 and the space 4 on the other side. It is waterproof.

By the way, the electric wire W drawn out from the electric wire through hole 2 to the other side of the vehicle body panel 1 avoids interference with a desired routing route, that is, the peripheral component 140, as shown in FIG. It is necessary to carry out the routing in a routing route that can secure the necessary clearance G with the peripheral component 140. Therefore, conventionally, the tape T is wound around the electric wire W, the clip 120 is mounted on the tape T, and the clip 120 is fixed to the vehicle body (not shown) to force the electric wire W to a desired path. The route was regulated.

JP, 2016-10165, A

However, in the above-mentioned conventional example, since the electric wire W avoids the interference with the peripheral component 140 and is a routing route which can secure the necessary clearance G between the peripheral component 140 and the peripheral component 140, the clip 120 which is the vehicle body fixing component is In addition to being necessary, the work of fixing the clip 120 to the vehicle body was extremely difficult and troublesome.

In particular, as shown in FIG. 16A, when it is necessary to shorten the length L from the vehicle body panel 1 to the clip 120 in order to secure the clearance G with the peripheral component 140, the wire W is attached to the clip 120. Since a large tension acts on the tape T, the winding fixing position of the tape T may shift due to deterioration over time, and the predetermined clearance G may not be secured.

Therefore, the present invention has been made to solve the above-mentioned problems, and a grommet grommet capable of arranging an electric wire in a desired route without the need for a vehicle body fixing component, which is difficult and which does not require a troublesome work. And a wire harness having a grommet.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
1 to 5 show a first embodiment of the present invention. 1 to 4, a circular electric wire through hole 2 is formed in a vehicle body panel 1. The electric wire (electric wire assembly) W of the wire harness is penetrated through the electric wire through hole 2. The electric wire W of the wire harness is laid out by passing through the electric wire through hole 2 so as to extend over the space 3 (shown in FIG. 3 etc.) on one side of the vehicle body panel 1 and the space 4 (shown in FIG. 3 etc.) on the other side. To be done. The wire harness has a grommet 10 attached to the outer circumference of the electric wire W. The electric wire through hole 2 of the vehicle body panel 1 is closed by the grommet 10. Hereinafter, the structure of the grommet 10 will be described in detail.

The grommet 10 is attached to the wire through hole 2 from the space 3 on one side of the vehicle body panel 1. The grommet 10 includes a grommet main body 11 formed of a flexible material (for example, a rubber material), an inner protector 20 disposed inside the grommet main body 11 and formed of a material having higher rigidity than the grommet main body 11, and an inner protector 20. And a path regulating member 30 fixed to the.

The grommet main body 11 has a tubular shape in which the electric wire W is routed, and is provided on the large-diameter tubular portion 12 having the inner fitting groove 13 on the inner peripheral side, and on the vehicle body panel 1 side of the large-diameter tubular portion 12. Also, a lip portion 15 and an electric wire holding tubular portion 19 provided on the opposite side of the large diameter tubular portion 12 to the vehicle body panel 1 side are provided, and these are integrally provided. The large-diameter cylindrical portion 12 has a larger diameter than the electric wire through hole 2. The inner fitting groove 13 is formed over the entire circumference of the large-diameter cylindrical portion 12. The outer peripheral edge of the inner protector 20 is fitted in the inner fitting groove 13. As a result, the grommet body 11 and the inner protector 20 are fixed. Further, the shape of the grommet main body 11, especially the large-diameter cylindrical portion 12 is maintained by the inner protector 20.

The lip portion 15 is provided so as to project from the outer peripheral surface of the large-diameter tubular portion 12 on the vehicle body panel 1 side. The lip portion 15 is formed of an inner peripheral lip portion 16 and an outer peripheral lip portion 17. The inner peripheral lip portion 16 and the outer peripheral lip portion 17 are continuously formed over the entire circumference of the large-diameter cylindrical portion 12.

Before the grommet 10 is attached to the electric wire through hole 2, the inner peripheral lip portion 16 projects from the root toward the central axis direction, and the tip side thereof is inclined in the direction of opening outward with respect to the central axis. The outer peripheral lip portion 17 projects in a direction that opens outward with respect to the central axis direction. In the state where the grommet 10 is attached to the wire through hole 2, the inner peripheral lip portion 16 and the outer peripheral lip portion 17 are elastically deformed in a direction to fall to the outer peripheral edge surface of the large-diameter cylindrical portion 12, and the wire through hole of the vehicle body panel 1 is formed. It is closely attached to the peripheral surface of 2. This prevents water and the like from entering the grommet 10 through the gap between the one side surface of the vehicle body panel 1 and the lip portion 15. 2, 3, and 5, the inner peripheral lip portion 16 and the outer peripheral lip portion 17 show a state before the grommet 10 is attached to the electric wire through hole 2.

The electric wire holding tubular portion 19 has an inner diameter slightly smaller than or substantially the same as the outer diameter of the electric wire W. The electric wire holding tubular portion 19 is in contact with the outer peripheral surface of the electric wire W over a predetermined length, and a tape (not shown) is wound around the outer peripheral surface of the electric wire holding tubular portion 19. This prevents water and the like from entering the grommet 10 through the gap between the inner surface of the electric wire holding tubular portion 19 and the outer peripheral surface of the electric wire W.

The electric wire holding tubular portion 19 is formed of a flexible material (for example, a rubber material) as described above. As a result, the electric wire holding tubular portion 19 can be flexibly deformed together with the electric wire W, and the electric wire W drawn out to the space 4 (the mounting side of the grommet 10) on one side of the vehicle body panel 1 can have a desired path within the range of the flexural deformation. It is possible to arrange it in.

The inner protector 20 is formed of a pair of inner members 21 assembled with each other. Each inner member 21 includes an inner main body 22 having a semicircular shape when viewed from above, and a flange 28 protruding outward from the inner main body 22. The inner body portion 22 is provided at a semicircular side wall 23, an upper regulation wall portion 24 provided inward from the semicircular side wall 23, and a lower position spaced from the upper regulation wall portion 24. The lower regulation wall portion 25 is provided. A semi-arc shaped fitting groove 26 is formed in each inner body portion 22 and is surrounded by the upper regulation wall portion 24 and the lower regulation wall portion 25. In a state where the pair of inner members 21 are combined, the two fitting grooves 26 form a circumferential groove shape.

Each upper regulation wall portion 24 is formed with a notch 27 having a triangular shape when viewed from above. In the state where the pair of inner members 21 are combined, the two cutout portions 27 form a square cutout shape.

A lock portion 29 is provided near the united surface of each inner member 21. The pair of inner members 21 are locked by both lock portions 29 in a state where their united surfaces are butted against each other.

Panel locking claws 29A are provided on the outer peripheral surface of each semicircular side wall 23 at intervals. Each panel locking claw 29A is elastically deformable in the direction in which the tip end side approaches the semicircular side wall 23. The vehicle body panel 1 is sandwiched by the plurality of panel locking claws 29A of the inner protector 20 and the lip portion 15 of the grommet body 11. Due to this clamping force, the grommet 10 is attached to the wire through hole 2 of the vehicle body panel 1.

The route restricting member 30 is made of a material having a rigidity capable of at least maintaining its own shape with the electric wire W accommodated therein. The route restricting member 30 is a tubular body that houses the electric wire W therein. The route regulating member 30 extends along the desired wiring direction of the electric wire W. Specifically, the path restricting member 30 is bent at a position near the base end position fixed to the inner protector 20, and extends straight in an oblique direction from the bent position to the tip.

The route restricting member 30 includes a route restricting main body 31, a cover 33 connected to the route restricting main body 31 via a hinge portion 32, and a base flange portion 34 attached to the base end of the route restricting main body 31 and the cover 33. Is equipped with. The path restricting body 31 has a U-shaped wall surface portion extending along a desired wiring direction of the electric wire W, and an electric wire housing chamber 35 is formed in the U-shaped wall surface portion. The cover 33 is provided so that the electric wire storage chamber 35 can be opened and closed by the hinge portion 32. At the closed position, the path restricting body 31 and the cover 33 are locked by the locking portions 36 of each other.

The base flange portion 34 of the path restricting member 30 is fitted into the circumferential fitting groove 26 of the inner protector 20 (the pair of inner body portions 22 that are united together), and the tip side of the base flange portion 34 is the inner side. The protector 20 (the pair of upper regulation wall portions 24 combined together) is projected to the outside from a pair of rectangular notches 27. The path restricting member 30 is fixed to the inner protector 20 by the notch 27 and prevented from rotating by the fitting groove 26 so as to be protruded in a predetermined direction. That is, the route restricting member 30 extends along the predetermined direction in the space 4 on the other side of the vehicle body panel 1 and restricts the route of the electric wire W drawn to the space 4 on the other end side of the vehicle body panel 1. .. As shown in FIG. 5A, the route restricting member 30 routes the electric wire W in a routing route that avoids interference with the peripheral component 140 and can secure a necessary clearance G with the peripheral component 140. To do.

The base flange portion 34 of the path regulation member 30 is fitted into the fitting groove 26 of the inner protector 20 without any gap. This prevents the path restricting member 30 from being displaced in the horizontal direction or the swinging direction. As a result, the routing path of the internal electric wire W is uniquely specified.

Next, the procedure for assembling the grommet 10 will be described. The electric wire W is accommodated in the path regulation member 30. That is, as shown in FIG. 4A, the electric wire W is routed in the path regulation body 31 with the cover 33 opened, and the cover 33 is closed.

Next, the path regulating member 30 is attached to the inner protector 20. That is, as shown in FIG. 4B, the base collar portion 34 of the path restricting member 30 is set between the pair of inner members 21, and the base collar portion 34 is fitted into the fitting groove 26 of the pair of inner members 21. Meanwhile, the pair of inner members 21 are united (see FIG. 4C).

Next, the inner protector 20 is fitted to the grommet body 11 through which the electric wire W is passed. That is, as shown in FIG. 4D, the large-diameter cylindrical portion 12 of the grommet body 11 is elastically deformed in the expanding direction, and the brim portion 28 of the inner protector 20 is fitted into the inner fitting groove 13 of the grommet body 11. With this, the grommet 10 is attached to the electric wire W.

Next, the electric wire W is passed through the electric wire through hole 2 of the vehicle body panel 1, and the grommet 10 is pushed into the electric wire through hole 2 from the space 3 on one side of the vehicle body panel 1 with the path regulating member 30 as the insertion tip side. Then, the route restricting member 30 projects from the wire through hole 2 into the space 4 on the other side of the vehicle body panel 1, and then the inner protector 20 enters the wire through hole 2. Here, each panel locking claw 29A of the inner protector 20 abuts on the peripheral edge of the wire through hole 2, but each panel locking claw 29A is elastically deformed to allow the inner protector 20 to be inserted into the wire through hole 2. .. When the inner protector 20 is inserted to the insertion completion position, each panel locking claw 29A elastically returns to lock with the peripheral edge of the vehicle body panel 1 on the opposite side of the wire through hole 2. The vehicle body panel 1 is clamped by the plurality of panel locking claws 29A and the lip portion 15 of the grommet body 11. Due to this gripping force, the grommet 10 is attached to the electric wire through hole 2 of the vehicle body panel 1.

As described above, the grommet 10 is formed of the grommet main body 11 that covers the electric wire W on one side of the vehicle body panel 1 and is in close contact with the peripheral edge of the electric wire through hole 2, and a member having higher rigidity than the grommet main body 11. The inner protector 20 is provided inside the grommet main body 11, and a route restricting member 30 that is fixed to the inner protector 20 and restricts the route of the electric wire W drawn to the other end side of the vehicle body panel 1. In this way, the route regulating member 30 is attached to the grommet 10, and the route regulating member 30 regulates the route of the electric wire W drawn to the other end side of the vehicle body panel 1 so that the electric wire W can be routed in a desired route. More specifically, the electric wire W drawn to the other side of the vehicle body panel 1 is required to avoid interference with the peripheral component 140 and to be provided between the peripheral component 140 and the peripheral component 140, as shown in FIG. It is possible to use a routing route that can secure the clearance G. As described above, unlike the conventional example, the vehicle body fixing component (for example, clip) is not necessary, and the electric wire W can be routed in a desired route without performing difficult and troublesome work.

The route restricting member 30 is a tubular body that houses the electric wire W therein. That is, in the conventional example, as shown in FIG. 16B, the electric wire W drawn to the other side of the vehicle body panel 1 is restricted only at the position of the clip 120, and moreover, the electric wire insertion passage in the inner protector 110. Since 110a has a gap between the wire W and the wire W, there is a degree of freedom in the routing route from the inner protector 110 to the position of the clip 120, and the routing route may be displaced as shown by a virtual line. , And is not uniquely specified. Therefore, a situation occurs in which the electric wire W cannot secure the necessary clearance G with the peripheral component 140. On the other hand, in the present embodiment, as shown in FIG. 5B, in the electric wire W drawn to the other side of the vehicle body panel 1, the route restricting member 30 is supported by the inner protector 20 with substantially no space, and In the section from the inner protector 20 to the tip of the route restricting member 30, the route W of the electric wire W is uniquely specified by the route restricting member 30 without any degree of freedom. The clearance G can be reliably ensured.

The route restricting member 30 is a tubular body that houses the electric wire W therein. Therefore, the route regulating member 30 has a function of protecting the electric wire W (protector function).

(Second embodiment)
6 to 12 show a second embodiment of the present invention. As shown in FIGS. 6 to 9, the grommet 10A of the second embodiment is composed of the grommet main body 11, the inner protector 20 and the route restricting member 40 as in the first embodiment, but the route is defined in the grommet body 11. Only the structure of the restriction member 40 is different. The route regulating member 30 of the first embodiment cannot change the routing route of the electric wire W, but the route regulating member 40 of the second embodiment can change the routing route of the electric wire W. This will be described below.

The route regulating member 40 is a tubular body that houses the electric wire W therein. In detail, the route regulating member 40 is composed of a fixed side route regulating part 41 and a movable side route regulating part 51 connected to the fixed side route regulating part 41 via a hinge part 50 as one member. The fixed-side route restricting portion 41 includes a fixed-side route restricting main body 42, a fixed-side cover 44 connected to the fixed-side route restricting main body 42 via a hinge 43, and a fixed-side route restricting main body 42 and a fixed-side cover 44. The base flange portion 45 attached to the base end portion is provided. The movable-side route restricting portion 51 includes a movable-side route restricting main body 52 and a movable-side cover 54 connected to the movable-side route restricting main body 52 via a hinge portion 53.

The fixed-side path restricting portion 41 has a shape bent in an arc shape when viewed from the closed surface side of the fixed-side cover 44. The movable-side route restricting portion 51 has a straight form.

As shown in FIG. 8, the fixed-side route regulation main body 42 and the fixed-side cover 44 both have a side surface portion on the tip side (a portion connecting the movable-side route regulation portion 51) in the routing direction of the route of the electric wire W. Four positioning holes (positioning fixing portions) 46 are provided at positions left and right at intervals. Four positioning claws (positioning fixing portions) 47 are provided on the upper surface of the fixed-side path regulating body 42 at intervals in the routing direction of the path of the electric wire W. The respective positioning holes 46 and the corresponding positioning claws 47 are set not at the same position with respect to the routing direction of the path of the electric wire W but at a shifted position.

On the other hand, one positioning claw (positioning fixing part) 57 shifts to the left and right on the side surface parts of both the movable side path regulating body 52 and the movable side cover 54 on the base end side (the part connecting the fixed side path regulating part 41). It is provided at the position where Two positioning holes (positioning fixing portions) 56 are provided on the upper surface of the movable-side path regulation body 52 at intervals in the routing direction of the path of the electric wire W. The positioning claw 57 and one positioning hole 56 are set at positions shifted in the wiring direction of the electric wire W, and the positioning claw 57 and another positioning hole 56 are set at the same position in the wiring direction of the electric wire W. Has been done.

The left and right positioning claws 57 of the movable side path restricting portion 51 can be selectively fitted into the left and right four positioning holes 46 of the fixed side path restricting portion 41, and similarly, the two positioning holes 56 of the movable side path restricting portion 51. Can be selectively fitted with two or one of the four positioning claws 47 of the fixed-side path restricting portion 41. That is, the four connection positions can be selected by selecting the positioning holes 46 and 56 and the positioning claws 47 and 57, and the connection angle (tilt angle) of the movable-side path restricting portion 51 to the fixed-side path restricting portion 41 can be selected by the selection of the connecting positions. Is changed.

For example, as shown in FIG. 9A, when the positioning claw 57 of the movable-side route restricting portion 51 is fitted into the most distal positioning hole 46 of the fixed-side route restricting portion 41, the extending direction of the route restricting member 40 is increased. Becomes an angle a with respect to the surface of the vehicle body panel 1. As shown in FIG. 9B, when the positioning claw 57 of the movable side path regulating portion 51 is fitted into the second positioning hole 46 from the tip side of the fixed side path regulating portion 41, the path regulating member 40 is extended. The direction is the b angle (b>a) with respect to the surface of the vehicle body panel 1.

Further, similarly to the first embodiment, the route regulating member 40 is formed of a material having rigidity that can at least maintain its own shape in the state where the electric wire W is accommodated. The fixed-side route regulation main body 42 and the movable-side route regulation main body 52 have a U-shaped wall surface portion extending along a desired routing direction of the electric wire W, and the electric wire accommodation chamber 48, in the U-shaped wall surface portion. 58 is formed. The fixed side cover 44 and the movable side cover 54 are provided so that the electric wire storage chambers 48 and 58 can be opened and closed by the hinge portions 43 and 53, respectively. At the closed position, the fixed-side path regulation main body 42 and the fixed-side cover 44, and the movable-side path regulation main body 52 and the movable-side cover 54 are locked by their respective locking portions 59.

The structures of the grommet body 11 and the inner protector 20 are the same as those in the first embodiment, and therefore, the same parts in the drawings are designated by the same reference numerals and the description thereof will be omitted.

Next, a procedure for assembling the grommet 10 will be described. As shown in FIG. 11A, with the fixed-side cover 44 and the movable-side cover 54 opened, the movable-side route regulating main body 52 is positioned in an arbitrary positioning hole 46 and a positioning claw 47 of the fixed-side route regulating main body 42. The claw 57 and the positioning hole 56 are fitted to each other to determine the connecting position, that is, the connecting angle. For example, in FIG. 11A, the positioning claw 57 and the positioning hole 56 of the movable side path regulation body 52 are fitted into the positioning hole 46 and the positioning claw 47 on the most distal side of the fixed side path regulation body 42, and the smallest inclination is obtained. The connection angle is used.

Next, the electric wire W is routed in the fixed-side route regulation main body 42 and the movable-side route regulation main body 52, and the fixed-side cover 44 is closed to the fixed-side route regulation main body 42 as shown in FIG. 11B.

Next, as shown in FIG. 11C, the movable side cover 54 is closed with respect to the movable side path regulating main body 52. Then, as shown in FIG. 11D, the positioning claw 57 of the movable side cover 54 fits into the positioning hole 46 of the fixed side cover 44.

The subsequent assembling procedure is the same as in the first embodiment. That is, as shown in FIGS. 12A and 12B, the path regulating member 40 is fixed to the inner protector 20. Next, as shown in FIG. 12C, the inner protector 20 is fitted to the grommet body 11 through which the electric wire W is passed. Thus, the grommet 10A is attached to the electric wire W. Next, the grommet 10A is attached to the electric wire through hole 2 of the vehicle body panel 1 by the same procedure as in the first embodiment, and the process is completed.

As described above, also in the second embodiment, similarly to the first embodiment, the grommet 10A covers the electric wire W on one side of the vehicle body panel 1 and the grommet main body 11 that is in close contact with the peripheral edge of the electric wire through hole 2, and the grommet main body. An inner protector 20 formed of a member having higher rigidity than that of the grommet main body 11 and disposed inside the grommet body 11, and a path for fixing the path of the electric wire W fixed to the inner protector 20 and drawn to the other end side of the vehicle body panel 1. The regulation member 40 is provided. In this way, the route regulating member 40 is attached to the grommet 10A, and the route regulating member 40 regulates the route of the electric wire W drawn to the other end side of the vehicle body panel 1, that is, the electric wire W can be a desired route. More specifically, the electric wire W drawn to the other side of the vehicle body panel 1 avoids interference with peripheral parts (not shown) and can secure a necessary clearance with the peripheral parts. You can As described above, unlike the conventional example, the vehicle body fixing component (for example, clip) is not necessary, and the electric wire W can be routed in a desired route without performing difficult and troublesome work.

The route restricting member 40 is provided so that the route of the electric wire W can be changed. Therefore, even if the arrangement of peripheral parts (not shown) in the space 4 on the other side of the vehicle body panel 1 is changed, it is possible to cope with the situation without newly constructing the route regulating member 40.

The path restricting member 40 has a fixed side path restricting section 41 fixed to the inner protector 20 and a movable side path restricting section 51 connected to the fixed side path restricting section 41, and is movable with the fixed side path restricting section 41. The side path restricting portion 51 is provided with a plurality of positioning fixing portions (positioning holes 46 and 56 and positioning claws 47 and 57) for changing the route of the electric wire W. Therefore, one of the plurality of positioning fixing portions is provided. If is selected, the route of the electric wire W can be easily changed, and workability is good.

The path regulation member 40 is formed of one member. Therefore, workability such as wiring arrangement is good.

(Modification)
