Description

The present invention relates to a wire harness protector that houses the wire harness to be protected.

For example, to protect a wire harness arranged in the body of an automobile, a cylindrical resin protector that houses the wire harness inside is used. In a protector that houses the wire harness through an opening in the main body, the wire harness can be protected by the protector by closing the opening of the main body with a cover after the wire harness is housed.

However, the wire harness housed in the main body of the protector needs to be fixed to the main body using a fastener or the like. If the wire harness is fixed to the main body before the opening of the main body is closed with the cover, the opening of the main body cannot be closed with the cover to protect the wire harness until the work of fixing the wire harness is completed.

On the other hand, if the main body is provided with a portion where the wire harness is still exposed outside the main body even after the opening is covered with the cover, the wire harness can be fixed to the main body even after the opening of the main body is covered with the cover. However, the portion of the wire harness fixed to the main body cannot be protected by the protector. Therefore, a protector has been proposed in which a hinge is provided on the cover, and this hinge allows one portion of the cover to be opened and closed independently of the other portions.

In this protector, after the wire harness is housed and the opening of the main body is closed with the cover, part of the cover is opened to expose the part of the main body and the wire harness is fixed to it, and after the wire harness is fixed, the part of the cover is closed again. This ensures the protection of the wire harness after it is fixed to the main body without compromising the protection of the wire harness between being housed in the main body and being fixed to it (for example, Patent Document 1).

However, because the hinges on the cover are thin, repeated opening and closing of the cover at a large rotation angle may result in excessive load being applied to the hinge, which may cause deformation or damage due to fatigue deterioration. If the hinge is deformed or damaged, this may interfere with the opening and closing of the cover, or part of the cover may fall off from the hinge.

The present invention was made in consideration of the problems inherent in the conventional technology. The object of the present invention is to prevent excessive load from being applied to the hinge that allows the part of the cover that covers the opening of the main body to be opened and closed.

Embodiments of the present invention will be described below with reference to the drawings. The same or equivalent parts and components are denoted by the same or equivalent reference numerals throughout the drawings.

The embodiments shown below are examples of devices that embody the technical ideas of this invention, and the technical ideas of this invention do not specify the materials, shapes, structures, arrangements, etc. of each component part to those described below. For example, the dimensional ratios in the drawings have been exaggerated for the convenience of explanation and may differ from the actual ratios. The technical ideas of this invention may be modified in various ways within the scope of the claims.

[First embodiment]
Fig. 1 is a perspective view of a protector according to a first embodiment of the present invention. A protector 10 (corresponding to a wire harness protector in the claims) according to this embodiment shown in Fig. 1 has a main body 20 into which a wire harness (not shown) is housed through an opening 21, and a cover 30 attached to the main body 20 to cover the opening 21.

Figure 2 is a perspective view of the protector 10 disassembled into the main body 20 and the cover 30. The main body 20 shown in Figure 2 is a resin molded product. The main body 20 has a bottom plate 22 arranged along the wiring path of a wire harness (not shown), and a pair of side wall plates 23, 23. Each side wall plate 23 stands upright from both edges of the bottom plate 22 in the width direction that intersects with the extension direction of the bottom plate 22. The opening 21 of the main body 20 is formed in a portion facing the bottom plate 22. The main body 20 is also open at both ends 24, 25 in the extension direction of the bottom plate 22.

The bottom plate 22 and each side wall plate 23 have a shape that matches the mounting surface of a vehicle (not shown) to which the protector 10 is attached. On one side wall plate 23, an attachment piece 26 protrudes from a location near one end 24 of the main body 20 toward the outside of the main body 20. The attachment piece 26 has an attachment hole 27. The main body 20 can be fixed to a vehicle (not shown), for example, using a fastener such as a bolt inserted into the attachment hole 27. Locking projections 28, 28, ... are formed at multiple locations on each side wall plate 23 of the main body 20.

The cover part 30 is a resin molded product, like the main body part 20. The cover part 30 has a top plate 31 of a shape corresponding to the opening 21 of the main body part 20. When the cover part 30 is placed between the side wall plates 23, 23 of the main body part 20, the opening 21 of the main body part 20 is blocked by the top plate 31. The top plate 31 is provided with a plurality of locking parts 32, 32, .... Each locking part 32 is disposed on both edges of the width direction W of the top plate 31 that intersects with the extension direction of the top plate 31 (corresponding to the direction intersecting with the rotation direction of the opening and closing lid body in the claims). When the opening 21 of the main body part 20 is blocked with the cover part 30, each locking part 32 of the cover part 30 is locked to each locking protrusion 28 at the corresponding position of the main body part 20, and the cover part 30 is fixed to the main body part 20.

The top plate 31 is constructed by connecting a fixed lid body 33 and an opening/closing lid body 34 with a thin hinge 35. When the opening 21 of the main body 20 is covered with the cover 30, the portion of the opening 21 on one end 24 side is covered by the fixed lid body 33, and the remaining portion on the other end 25 side is covered by the opening/closing lid body 34. The portion of the opening 21 on the other end 25 side can be opened and closed by releasing the engagement between the locking portion 32 of the opening/closing lid body 34 and the corresponding locking protrusion 28 of the main body 20 and rotating the opening/closing lid body 34.

An attachment portion 36 is formed on the surface of the opening/closing cover 34. The cover portion 30 can be fixed to the vehicle, for example, by inserting and engaging an attachment piece provided on the vehicle (not shown) into the attachment portion 36. Note that the attachment piece (not shown) of the vehicle inserted into the attachment portion 36 can be engaged with the attachment portion 36, for example, by engaging a locking protrusion (not shown) of the attachment portion 36 with a locking hole (not shown) of the attachment piece.

In the protector 10 of the present embodiment described above, when the opening/closing lid 34 of the cover 30 is rotated, the portion of the opening 21 of the main body 20 on the other end 25 side that is blocked by the opening/closing lid 34 is opened or closed. When the opening/closing lid 34 is rotated, the hinge 35, which serves as a fulcrum, deforms in the direction of rotation of the opening/closing lid 34. The amount of deformation of the hinge 35 depends on the rotation angle of the opening/closing lid 34.

Therefore, if the opening/closing lid 34 is repeatedly rotated at a large angle to open and close part of the opening 21, excessive load may be applied to the hinge 35, causing deformation or damage to the hinge 35 due to fatigue deterioration. If the hinge 35 is deformed or damaged, the rotation path of the opening/closing lid 34 may change, causing interference with surrounding structures and hindering the opening and closing of the opening 21. Alternatively, the opening/closing lid 34 may fall off from the hinge 35 of the cover part 30, making it impossible to cover the part of the opening 21 on the other end 25 side of the main body part 20.

Therefore, in the protector 10 of this embodiment, a restricting portion that restricts excessive rotation of the opening/closing lid body 34 relative to the fixed lid body 33 of the cover part 30 is provided on both the fixed lid body 33 and the opening/closing lid body 34.

3 is an enlarged perspective view of the main part of the protector 10 of this embodiment. In the protector 10 of this embodiment, as shown in FIG. 3, the regulating portion of the fixed cover 33 is constituted by a regulating piece 37 (corresponding to the fixed regulating piece in the claims) protruding from a portion near the end face 39 (corresponding to the hinge connection portion of the fixed cover in the claims) to which the hinge 35 is connected. In the protector 10 of this embodiment, the regulating portion of the opening and closing cover 34 is constituted by a regulating piece 38 (corresponding to the movable regulating piece in the claims) protruding from a portion near the end face 40 (corresponding to the hinge connection portion of the opening and closing cover in the claims) to which the hinge 35 is connected. Each of the regulating pieces 37, 38 of the fixed cover 33 and the opening and closing cover 34 has a width that covers the entire width direction W of the top plate 31.

Figure 4 shows the hinge 35 of the cover 30, with Figure 4(a) being an enlarged side view of the hinge 35 when the opening/closing lid 34 has been rotated slightly from the position where it closes the end 25 of the opening 21 of the main body 20. Figure 4(b) is an enlarged side view of the hinge 35 when the opening/closing lid 34 has been rotated a predetermined angle from the position where it closes the end 25 of the opening 21.

As shown in FIG. 4(a), the end faces 39, 40 to which the hinges 35 of the fixed cover 33 and the opening/closing cover 34 are connected are arranged almost parallel when the opening/closing cover 34 is rotated slightly from the position where it closes the end 25 side of the opening 21 of the main body 20. When the opening/closing cover 34 is rotated further from this state, as shown in FIG. 4(b), the tips of the regulating pieces 37, 38 come into contact with each other when the opening/closing cover 34 rotates a predetermined angle θ from the position where it closes the end 25 side of the opening 21. In other words, the regulating piece 37 of the fixed cover 33 extends on the rotation path of the rotating cover 34 having the regulating piece 38, and abuts against the regulating piece 38 of the rotating cover 34 that has rotated a predetermined angle θ.

When the tips of the restricting pieces 37, 38 come into contact with each other, further rotation of the opening/closing lid body 34 relative to the fixed lid body 33 is restricted. In other words, the rotation angle of the opening/closing lid body 34 relative to the fixed lid body 33 is restricted to a range from zero, at which the opening/closing lid body 34 closes the portion of the opening 21 on the end 25 side, to a predetermined angle θ.

Therefore, even when the opening/closing cover 34 is rotated, the hinge 35 is always only slightly curved. Therefore, even if the opening/closing cover 34 is repeatedly rotated, it is unlikely that a large load will be applied to the hinge 35, causing deformation or damage due to fatigue deterioration.

Figure 5 shows the hinge portion of a typical protector cover, with Figure 5(a) being an enlarged side view of the hinge portion when the opening/closing lid is rotated slightly from the position where the opening of the main body is closed. Also, Figure 5(b) is an enlarged side view of the hinge portion when the opening/closing lid is fully open.

As shown in FIG. 5(a), a typical protector 100 does not have a protrusion or other structure on the fixed lid body 133 and the opening/closing lid body 134 of the cover part 130 that covers an opening (not shown) of the main body part 120 to restrict the amount of rotation of the opening/closing lid body 134 relative to the fixed lid body 133.

Therefore, in a typical protector 100, the opening/closing lid 134 can be rotated until it overlaps the fixed lid 133 and is fully open, as shown in FIG. 5(b). When the opening/closing lid 134 is rotated fully open, the hinge 135 bends at an acute angle and is significantly deformed. For this reason, in a typical protector 100, repeated rotation of the opening/closing lid 134 places a large load on the hinge 135, which may cause deformation or damage to the hinge 135 due to fatigue deterioration.

In contrast, according to the protector 10 of this embodiment, the rotation angle of the opening/closing cover 34 relative to the fixed cover 33 is restricted to a range of a predetermined angle θ from the position where the end 25 side of the opening 21 of the main body 20 is closed, and the amount of deformation of the hinge 35 is kept small. Therefore, it is possible to prevent excessive load from being applied to the hinge 35 due to repeated rotation of the opening/closing cover 34.

In addition, according to the protector 10 of this embodiment, the regulating pieces 37, 38 of each lid body 33, 34 are protruded from the end faces 39, 40 to which the hinges 35 of each lid body 33, 34 are connected. Therefore, the height of each regulating piece 37, 38 required for the regulating piece 38 to abut against the regulating piece 37 of the fixed lid body 33 when the opening/closing lid body 34 is rotated by a predetermined angle θ can be kept low.

[Modification of the first embodiment]
The regulating pieces 37, 38 of the fixed cover 33 and the opening/closing cover 34 do not have to have a width that covers the entire width direction W of the top plate 31 as shown in Fig. 3. Fig. 6 is an enlarged perspective view of a main part of a protector according to a modified example of the first embodiment of the present invention. For example, as in a modified protector 50 (corresponding to a wire harness protector in the claims) shown in Fig. 6, the regulating pieces 37, 38 of the fixed cover 33 and the opening/closing cover 34 may be provided to protrude only from a part of the width direction W of the top plate 31. However, when the opening/closing cover 34 is rotated from a position where the opening 21 of the main body 20 is closed to a predetermined angle θ, the regulating pieces 37, 38 need to be arranged in a positional relationship in which the tips of the regulating pieces 37, 38 come into contact with each other as shown in Fig. 4(b).

[Second embodiment]
Fig. 7 shows a protector according to a first embodiment of the present invention, and Fig. 7(a) is an enlarged perspective view of the main part of the protector. Fig. 7(b) is an enlarged cross-sectional view of the hinge part in the state where the opening and closing lid of the cover part in Fig. 7(a) is fully opened. As shown in Fig. 7(a), in a protector 60 (corresponding to a wire harness protector in claims) of this embodiment, a recessed part 61 and a protruding part 62 are provided on each of the restricting pieces 37, 38 of the fixed lid 33 and the opening and closing lid 34 of the cover part 30, respectively.

The recess 61 and the protrusion 62 are respectively provided by extending the ends of the regulating pieces 37, 38 of the fixed cover 33 and the opening/closing cover 34 of the protector 10 of the first embodiment shown in FIG. 3. In the width direction W of the top plate 31, the recess 61 and the protrusion 62 are arranged at the same position. Also, the recess 61 has a groove width corresponding to the protrusion width of the protrusion 62 in the width direction W of the top plate 31. The protector 60 of this embodiment has the same configuration as the protector 10 of the first embodiment, except that the recess 61 and the protrusion 62 are respectively provided on the regulating pieces 37, 38 of the fixed cover 33 and the opening/closing cover 34.

In the protector 60 of this embodiment, the end faces 39, 40 to which the hinges 35 of the fixed cover 33 and the opening/closing cover 34 are connected are arranged almost parallel when the opening/closing cover 34 is rotated slightly from the position where the end 25 side of the opening 21 of the main body 20 is closed. When the opening/closing cover 34 is rotated further from this position, as shown in FIG. 7(b), the tips of the regulating pieces 37, 38 come into contact with each other when the opening/closing cover 34 rotates a predetermined angle θ from the position where the opening/closing cover 34 closes the end 25 side of the opening 21. Therefore, the rotation angle of the opening/closing cover 34 relative to the fixed cover 33 is restricted to a range from zero rotation angle to a predetermined angle θ, at which the opening/closing cover 34 closes the end 25 side of the opening 21.

Therefore, the protector 60 of this embodiment can achieve the same effects as the protector 10 of the first embodiment shown in FIG. 3.

In addition, in the protector 60 of this embodiment, when the opening/closing lid 34 is rotated slightly from the position where the end 25 side of the opening 21 of the main body 20 is closed, the convex portion 62 of the opening/closing lid 34 is inserted into the concave portion 61 of the fixed lid 33. Since the concave portion 61 has a groove width corresponding to the protrusion width of the convex portion 62, there is almost no gap in the width direction W of the top plate 31 between the convex portion 62 inserted into the concave portion 61 and the concave portion 61. Therefore, the movement of the opening/closing lid 34 in the width direction W of the top plate 31 relative to the fixed lid 33 is restricted by the concave portion 61 and the convex portion 62 inserted into the concave portion 61.

Therefore, according to the protector 60 of this embodiment, it is possible to prevent the application of a shear force or a torsional external force in a direction other than the rotational direction of the opening/closing cover 34 to the hinge 35 connecting the fixed cover 33 and the opening/closing cover 34 while the opening/closing cover 34 is being opened or closed.

Contrary to the protector 60 of this embodiment, the fixed lid body 33 of the cover part 30 and the regulating pieces 37, 38 of the opening and closing lid body 34 may each be provided with a protrusion 62 and a recess 61.

[Third embodiment]
Fig. 8 is an explanatory view showing an enlarged view of the hinge portion of the cover portion of the main body of the protector according to the third embodiment of the present invention in a state where the opening/closing lid is rotated slightly from the position where the opening is closed. As shown in Fig. 8, in a protector 70 (corresponding to a wire harness protector in the claims) of this embodiment, the restricting piece on the end face 39 of the fixed lid 33 is omitted, and the restricting piece 38 is provided only on the end face 40 of the opening/closing lid 34. The restricting piece 38 of the opening/closing lid 34 is provided to protrude in a direction inclined toward the hinge 35 side more than the restricting piece 38 of the opening/closing lid 34 in the protector 10 of the first embodiment shown in Fig. 3.

In the protector 70 of this embodiment, when the opening/closing lid 34 rotates a predetermined angle θ from the position where it closes the portion on the end 25 side of the opening 21, the tip of the regulating piece 38 comes into contact with the surface near the end face 39 of the fixed lid 33. Therefore, in the protector 70 of this embodiment, the portion near the end face 39 of the fixed lid 33 and the regulating piece 38 of the opening/closing lid 34 respectively constitute the regulating portions of the fixed lid 33 and the opening/closing lid 34.

According to the protector 70 of this embodiment, it is possible to obtain the same effect as the protector 10 of the first embodiment shown in FIG. 3. Note that, contrary to the protector 70 of this embodiment, the restricting piece 38 on the end face 40 of the opening and closing lid 34 may be omitted, and the restricting piece 37 may be protruding only on the end face 39 of the fixed lid 33. When the restricting piece 38 of the opening and closing lid 34 is omitted, and the restricting piece 37 is protruding only on the fixed lid 33, the restricting piece 37 of the fixed lid 33 is protruding in a direction inclined toward the hinge 35 side more than the restricting piece 37 of the fixed lid 33 in the protector 10 of the first embodiment shown in FIG. 3.

Even with this configuration, when the opening/closing cover 34 rotates a predetermined angle θ from the position where it closes the end 25 side of the opening 21, the tip of the restricting piece 37 comes into contact with the surface near the end face 40 of the opening/closing cover 34, restricting further rotation of the opening/closing cover 34 relative to the fixed cover 33. Therefore, the same effect as the protector 10 of the first embodiment shown in Figure 3 can be obtained.

Even if either the regulating piece 37 of the fixed cover 33 or the regulating piece 38 of the opening/closing cover 34 is omitted, the configuration of the regulating part that regulates the rotation of the opening/closing cover 34 can be simplified compared to the case where the regulating pieces 37, 38 are provided on both covers 33, 34, respectively.

In the above-described embodiments and their modified examples, the protectors 10, 50, 60, and 70 that protect wire harnesses routed in a vehicle have been described as examples. However, the present invention can also be widely applied to protectors that protect wire harnesses other than those of vehicles.

[Invention disclosed by the embodiment and its effects]
The above-described embodiment discloses the invention in the following aspects.

First, as the invention according to the first aspect, a wire harness protector is disclosed that includes a main body and a cover. The main body has an opening through which the wire harness to be protected is inserted and removed. The cover is attached to the main body and has a fixed lid that covers a part of the opening, an openable/closable lid that closes another part of the opening in an openable/closable manner, and a hinge that connects the fixed lid and the openable/closable lid. When the rotation angle of the openable/closable lid from the closed position relative to the fixed lid reaches a predetermined angle, the rotation is restricted by the contact between the restricting portion of the fixed lid and the restricting portion of the openable/closable lid.

According to the wire harness protector of the invention according to the first aspect, when the opening/closing cover is rotated relative to the fixed cover to open the other part of the opening, the hinge that serves as the fulcrum deforms in the direction of rotation of the opening/closing cover. At this time, the amount of deformation of the hinge corresponds to the size of the rotation angle of the opening/closing cover. Then, when the opening/closing cover is rotated to a predetermined angle from the position where the other part of the opening is closed, the two regulating parts of the fixed cover and the opening/closing cover come into contact with each other, and the rotation of the opening/closing cover relative to the fixed cover is regulated.

By restricting the rotation of the opening/closing lid body described above, the amount of deformation of the hinge that realizes the rotation of the opening/closing lid body relative to the fixed lid body in the rotation direction of the opening/closing lid body is restricted to the amount of deformation when the opening/closing lid body is rotated at a specified angle. Because the amount of deformation of the hinge is restricted, it is possible to prevent excessive load from being applied to the hinge due to repeated rotation of the opening/closing lid body relative to the fixed lid body.

Next, as a second aspect of the invention, a wire harness protector is disclosed in which the restricting portion of the fixed lid body has a fixed restricting piece that protrudes from the fixed lid body and extends onto the rotation path of the opening and closing lid body.

According to the wire harness protector of the invention in the second aspect, when the opening/closing lid is rotated relative to the fixed lid by more than a predetermined angle, the fixed lid's fixed restricting piece abuts against the opening/closing lid's restricting portion. This abutment restricts the opening/closing lid from rotating relative to the fixed lid by more than the predetermined angle.

Next, as a third aspect of the invention, a wire harness protector is disclosed in which the fixed restricting piece protrudes from the connection portion of the hinge in the fixed cover.

According to the third aspect of the invention, the wire harness protector has a fixed restricting piece protruding from the connection part of the hinge of the fixed lid that is closest to the opening/closing lid. By protruding the fixed restricting piece here, it is possible to keep low the height of the fixed restricting piece required to abut against the restricting part of the opening/closing lid that is being rotated by a predetermined angle or more relative to the fixed lid.

Next, as a fourth aspect of the invention, a wire harness protector is disclosed in which the restricting portion of the opening/closing lid has a movable restricting piece that protrudes from the opening/closing lid and is exposed to the outside of the main body portion that closes the opening with the cover portion.

According to the wire harness protector of the invention in the fourth aspect, when the opening/closing lid is rotated a predetermined angle relative to the fixed lid, the movable restricting piece of the opening/closing lid abuts against the restricting portion of the fixed lid. This abutment restricts the opening/closing lid from rotating beyond the predetermined angle relative to the fixed lid.

Next, as a fifth aspect of the invention, a wire harness protector is disclosed in which the movable restricting piece is protruding from the connection portion of the hinge in the opening and closing lid.

According to the wire harness protector of the invention relating to the fifth aspect, a movable restricting piece is provided to protrude from the connection part of the hinge of the opening/closing cover that is closest to the fixed cover. By providing the movable restricting piece to protrude here, it is possible to keep the height of the movable restricting piece low so that it abuts against the restricting part of the fixed cover when the opening/closing cover is rotated by a predetermined angle or more.

Next, as a sixth aspect of the invention, a wire harness protector is disclosed in which the regulating portion has a fixed regulating piece and a movable regulating piece. The fixed regulating piece is provided to protrude from the fixed lid body and extends on the rotation path of the opening/closing lid body. The movable regulating piece is provided to protrude from the opening/closing lid body and is exposed to the outside of the main body part that closes the opening with the cover part. Then, at an opening/closing angle of the opening/closing lid body that is equal to or less than the predetermined angle, the movement of the hinge in a direction intersecting the rotation direction of the opening/closing lid body is restricted by the recess of one of the regulating pieces and the protrusion of the other regulating piece inserted into the recess.

According to the wire harness protector of the invention according to the sixth aspect, when the opening/closing lid is rotated relative to the fixed lid by a predetermined angle or less, the convex portion of the regulating piece of one lid is inserted into the concave portion of the regulating piece of the other lid. The convex portion inserted into the concave portion is restricted by the concave portion from moving in a direction intersecting the rotation direction of the opening/closing lid. Therefore, the movement of the opening/closing lid relative to the fixed lid in a direction intersecting the rotation direction of the opening/closing lid is restricted by the insertion of the convex portion into the concave portion while the opening/closing lid is being opened or closed.

As a result, the external force applied to the hinge when the opening and closing lid is opened and closed is restricted to the rotational direction of the opening and closing lid, and it is possible to prevent external forces in the twisting direction or shear forces in directions other than the rotational direction of the opening and closing lid from being applied to the hinge.
