FIG. 1 is a perspective view showing an abnormal noise suppressing member 3 for suppressing generation of abnormal noise when the protective member 2 covering the electric wire 1 hits the electric wire 1. Below, the case where the protection member 2 is a corrugated tube and the protection member 2 covers the wire bundle 10 composed of the plurality of wires 1 will be described. The protective member 2 may be other than the corrugated tube, and the protective member 2 may cover only one electric wire 1. Hereinafter, the protection member 2 may be referred to as “corrugated tube 2”.

The noise suppressing member 3 is disposed inside the corrugated tube 2 and attached to the wire bundle 10 so as to partially cover the wire bundle 10. FIG. 2 is a diagram illustrating a state where the noise suppressing member 3 is attached to the wire bundle 10. As shown in FIG. 2, the noise suppressing member 3 is attached to the wire bundle 10 so as to cover a part of the wire bundle 10 in the extending direction.

FIG. 3 is a perspective view showing the corrugated tube 2. As shown in FIG. 3, the corrugated tube 2 is a cylindrical member in which annular convex portions 20 and annular concave portions 21 are alternately formed along the extending direction. The corrugated tube 2 is made of a resin such as polypropylene (PP), for example. Since the corrugated tube 2 is easily elastically deformed at a step portion between the annular convex portion 20 and the annular concave portion 21, the corrugated tube 2 itself has a property of being easily bent and deformed. The corrugated tube 2 is formed with one slit (elongated cut) 22 from end to end in the extending direction. The wire bundle 10 can be easily disposed in the corrugated tube 2 by splitting the corrugated tube 2 with the slits 22.

FIG. 4 is a view showing a cross-sectional structure of the corrugated tube 2 in a plane perpendicular to the extending direction thereof. In the corrugated tube 2, the annular protrusions 20 and the annular recesses 21 are alternately formed along the extending direction, so that the inner surface 200 is uneven as in the outer surface 210 as shown in FIG. 4. Is made. Specifically, on the inner surface 200 of the corrugated tube 2, an annular concave surface 201 that is recessed toward the outside of the corrugated tube 2 and an annular convex surface 202 that protrudes toward the inside of the corrugated tube 2 extend the corrugated tube 2. It is formed alternately along the direction.

The corrugated tube 2 having such a structure is inserted through the slit 22 with a wire bundle 10 to which the noise suppressing member 3 is attached as shown in FIG. Arranged in the corrugated tube 2.

As shown in FIGS. 1 and 2, the noise suppressing member 3 is a cylindrical member, and is formed of a synthetic rubber such as EPDM, for example. The noise suppressing member 3 has a cylindrical main body 30 that covers the wire bundle 10. The outer surface 300 of the main body 30 is provided with unevenness corresponding to the unevenness on the inner surface 200 of the corrugated tube 2. Specifically, on the outer surface 300 of the main body 30, an annular convex surface 301 corresponding to the annular concave surface 201 on the inner surface of the corrugated tube 2 that protrudes toward the outer side of the main body 30, and the inner side of the main body 30. An annular concave surface 302 corresponding to the annular convex surface 202 on the inner surface of the corrugated tube 2 is provided. The annular convex surface 301 of the main body 30 can enter the annular concave surface 201 of the corrugated tube 2, and the annular convex surface 202 of the corrugated tube 2 can enter the annular concave surface 302 of the main body 30. Yes. On the outer surface 300 of the main body 30, the annular convex surfaces 301 and the annular concave surfaces 302 are alternately formed along the direction in which the columnar through holes 320 of the main body 30 extend. In other words, on the outer surface 300 of the main body 30, the annular convex surface 301 and the annular concave surface 302 are alternately formed along the extending direction of the wire bundle 10 to which it is attached. In the example of FIGS. 1 and 2, two annular convex surfaces 301 and one annular concave surface 302 are provided on the outer surface 300 of the main body 30, but the number of the annular convex surfaces 301 and the annular concave surfaces 302 is limited to this. Absent. On the other hand, the inner surface 310 of the main body 30 is not uneven and has a flat curved surface.

Further, the main body 30 is provided with one slit (elongated gap) 31 along the extending direction of the through hole 320, that is, the space through which the wire bundle 10 passes. In other words, the main body 30 is provided with one slit 31 along the extending direction of the wire bundle 10 to which the main body 30 is attached. The slit 31 is provided from end to end in the extending direction of the through hole 320 so as to be connected to the through hole 320 in the main body 30. Therefore, both ends of the slit 31 are open.

Next, the process from attaching the noise suppressing member 3 to the wire bundle 10 and then covering the wire bundle 10 with the corrugated tube 2 will be described. That is, the manufacturing method of a wire harness provided with the wire bundle 10 to which the noise suppression member 3 is attached and the corrugated tube 2 covering the wire bundle 10 will be described.

When attaching the noise suppressing member 3 to the wire bundle 10, first, as shown in FIG. 5, using the manual work or a jig, the noise suppressing member 3 expands the slit 31 of the noise suppressing member 3. The main body 30 of the suppressing member 3 is elastically deformed. Next, as shown in FIG. 6, the wire bundle 10 (more specifically, a part of the wire bundle 10) is put inside the main body 30 from the slit 31 in a state where the slit 31 is expanded. And as FIG. 7 shows, the elastic deformation of the main-body part 30 is cancelled | released, and the width | variety of the slit 31 is returned. Thereby, the noise suppressing member 3 is attached to the wire bundle 10. In addition, the coating | covering material of each electric wire 1 of the electric wire bundle 10 is formed with vinyl chloride (PVC) or polyethylene (PE), for example.

When the noise suppressing member 3 is attached to the electric wire bundle 10, the electric wire bundle 10 (more specifically, the electric wire bundle 10, more specifically, from the slit 22 of the corrugated tube 2 so that the abnormal noise suppressing member 3 is positioned inside the corrugated tube 2. A part of the electric wire bundle 10 is put inside the corrugated tube 2. Thereby, as shown in FIGS. 8 and 9, the wire harness 100 in which the noise suppressing member 3 is located in the corrugated tube 2 and the wire bundle 10 is covered with the corrugated tube 2 is completed. FIG. 8 is a perspective view of the wire harness 100, and FIG. 9 is a view showing a structure inside the corrugated tube 2 in the wire harness 100. In FIG. 9, about the corrugated tube 2, the cross-sectional structure in the surface perpendicular | vertical to the extension direction is shown. After covering the wire bundle 10 with the corrugated tube 2, an adhesive tape may be wound around the corrugated tube 2 in order to prevent the slit 22 of the corrugated tube 2 from opening.

As shown in FIG. 9, in the wire harness 100, the unevenness of the outer surface 300 of the main body 30 of the noise suppressing member 3 and the unevenness of the inner surface 200 of the corrugated tube 2 corresponding to the unevenness are fitted. . That is, the noise suppressing member 3 is housed in the corrugated tube 2 so that the unevenness of the outer surface 300 of the main body 30 of the abnormal noise suppressing member 3 and the unevenness of the inner surface 200 of the corrugated tube 2 are fitted. In the wire harness 100, the annular convex surface 301 of the outer surface 300 of the main body 30 of the noise suppressing member 3 enters the annular concave surface 201 of the inner surface 200 of the corrugated tube 2, and both are in contact with each other. The diameter of the annular convex surface 301 coincides with the diameter of the annular concave surface 201. Further, the annular convex surface 202 of the inner surface 200 of the corrugated tube 2 enters the annular concave surface 302 of the outer surface 300 of the main body 30 of the noise suppressing member 3 so that they are in contact with each other. The diameter of the annular convex surface 202 and the diameter of the annular concave surface 302 are the same.

As mentioned above, since the main body part 30 which is arrange | positioned inside the protection member 2 and covers the wire bundle 10 is provided in the noise suppression member 3, the protection member 2 and the wire bundle 10 strike. Generation of abnormal noise can be suppressed. Therefore, it is possible to suppress abnormal noise from the inside of the protective member 2.

From the viewpoint of suppressing the generation of abnormal noise from the inside of the protective member 2, it is desirable that there is no play between the abnormal noise suppressing member 3 and the wire bundle 10 as much as possible. That is, it is desirable that as many wires 1 as possible be passed through the through holes 320 of the main body 30 of the noise suppressing member 3. Even when there is play between the noise suppressing member 3 and the electric wire bundle 10, the electric wire bundle is compared with the case where the electric wire bundle 10 is covered with the protective member 2 without being attached with the abnormal noise suppressing member 3. Since the play of 10 can be reduced, it is possible to suppress the generation of abnormal noise from the inside of the protection member 2.

Moreover, in the noise suppressing member 3 according to the present embodiment, the main body 30 is provided with the slits 31 along the extending direction of the space (through hole 320) through which the wire bundle 10 in the main body 30 passes. Therefore, as described above, the noise suppressing member 3 can be easily attached to the electric wire bundle 10 by inserting the electric wire bundle 10 into the main body 30 from the slit 31. Furthermore, even after attaching a terminal etc. to the edge part of each electric wire 1, since the noise suppression member 3 can be attached to the electric wire bundle 10, workability | operativity improves.

Further, as in the present embodiment, the protective member 2 is a corrugated tube, and the abnormal sound suppressing member 3 is accommodated in the corrugated tube. By fitting the unevenness with the unevenness on the inner surface of the corrugated tube, it is possible to suppress the positional deviation (more specifically, lateral deviation) of the noise suppressing member 3 in the protective member 2. Therefore, it is possible to suppress the generation of abnormal noise due to the displacement of the abnormal noise suppression member 3 within the protection member 2.

Even if the outer surface 300 of the main body portion 30 of the noise suppressing member 3 is not provided with irregularities, the electric wire bundle 10 and the protection member 2 are in contact with each other even when the main body portion 30 has a flat cylindrical shape. The generation of abnormal noise can be suppressed.

Further, the protective member 2 may be other than the corrugated tube. For example, the protective member 2 may be a tube having a flat outer surface and inner surface.

Further, the longer the protective member 2 is, the more noise suppressing members 3 may be attached to the wire bundle 10. Thereby, since many noise suppression members 3 can be arranged in the long protection member 2, even if the protection member 2 is long, the protection member 2 and the electric wire bundle 10 are difficult to hit, and noise is generated. Can be suppressed.

Alternatively, a plurality of types of abnormal noise suppressing members 3 having different lengths may be prepared, and the longer the abnormal noise suppressing member 3 may be attached to the electric wire bundle 10 as the protective member 2 covering the electric wire bundle 10 is longer. In other words, a plurality of kinds of noise suppressing members 3 having different numbers of the annular convex surfaces 301 and the annular concave surfaces 302 are prepared, and the longer the protective member 2 covering the wire bundle 10 is, the larger the numbers of the annular convex surfaces 301 and the annular concave surfaces 302 are. The noise suppressing member 3 may be attached to the wire bundle 10. Thereby, since the long noise suppression member 3 can be arrange | positioned in the long protection member 2, even if it is the long protection member 2, the said protection member 2 and the wire bundle 10 become difficult to hit, and an abnormal noise generate | occur | produces. This can be suppressed.

In addition, a plurality of types of noise suppressing members 3 having different diameters of the through holes 320 of the main body 30 are prepared. The noise suppressing member 3 having a small diameter of the through hole 320 of the main body 30 may be attached to the wire bundle 10. Thereby, the play between the wire bundle 10 and the noise suppressing member 3 can be reduced regardless of the diameter of the wire bundle 10. As a result, it is possible to further suppress the generation of abnormal noise from the inside of the protective member 2.

Further, the shape and material of the noise suppressing member 3 may be other shapes and materials. FIG. 10 is a perspective view showing an abnormal noise suppressing member 13 which is a modification of the abnormal noise suppressing member 3. FIG. 11 is a diagram illustrating a state in which the noise suppressing member 13 is attached to the wire bundle 10. In the example of FIG. 11, two abnormal noise suppressing members 13 are attached to the wire bundle 10.

As shown in FIGS. 10 and 11, the noise suppressing member 13 has a spherical main body 130 having a cylindrical through hole 140 at the center. The main body 130 is provided with one slit (elongated gap) 131 along the extending direction of the space through which the through hole 140, that is, the wire bundle 10 passes. In other words, the main body 130 of the noise suppressing member 13 is provided with one slit 131 along the extending direction of the wire bundle 10 to which the noise suppressing member 13 is attached. The slit 131 is formed from end to end in the extending direction of the through hole 140 so as to be connected to the through hole 140 in the main body 130. The abnormal noise suppressing member 13 is made of, for example, foamed polystyrene.

As shown in FIG. 11, the noise suppressing member 13 having such a structure is attached to the wire bundle 10 so as to cover a part of the wire bundle 10 in the extending direction. The electric wire bundle 10 to which the noise suppressing member 13 is attached is inserted into the corrugated tube 2 from the slit 22 of the corrugated tube 2 so that the noise suppressing member 13 is located in the corrugated tube 2 described above. It is done.

Next, a process from attaching the noise suppressing member 13 to the wire bundle 10 and then covering the wire bundle 10 with the corrugated tube 2 will be described.

In this modification, when attaching the noise suppressing member 13 to the wire bundle 10, unlike the above example, as shown in FIGS. 12 to 14, each of the plurality of wires 1 constituting the wire bundle 10 is provided. One by one from the slit 131 of the noise suppressing member 13 is pushed into the inside of the main body 130 of the noise suppressing member 13 (in the through hole 140). FIG. 12 shows a state before the electric wire 1 is pushed into the main body 130. FIG. 13 shows a state where one electric wire 1 is pushed from the slit 131 toward the inside of the main body 130. FIG. 14 shows a state after one electric wire 1 is pushed into the main body 130.

As shown in FIG. 13, the electric wire 1 is pushed into the slit 131 so as to expand the slit 131. At this time, the main body 130 undergoes elastic deformation. Then, when the electric wire 1 passes through the slit 131 and reaches the through hole 140, the elastic deformation of the main body 130 is released, and the width of the slit 131 returns to the original. In this manner, when each electric wire 1 constituting the electric wire bundle 10 is pushed into the main body 130 from the slit 131, the noise suppressing member 13 is attached to the electric wire bundle 10.

In this way, by pushing each of the plurality of electric wires 1 constituting the electric wire bundle 10 one by one from the slit 131 into the inside of the main body portion 130, the noise suppressing member 13 is changed as in this example. Even when it is formed of a member such as styrene foam that is not easily elastically deformed, the noise suppressing member 13 can be easily attached to the wire bundle 10. Furthermore, even if the diameter of the electric wire 1 to which the corrugated tube 2 is attached is changed, the electric wire 1 (more specifically, part of the electric wire 1) can be easily put inside the main body 130. That is, the noise suppressing member 13 can correspond to the electric wires 1 having various diameters. FIG. 15 is a diagram showing a state in which the electric wire 1 that is thicker than the electric wire 1 shown in FIGS. 12 to 14 is pushed inward from the slit 131 toward the inside of the main body 130.

When the noise suppressing member 13 is attached to the wire bundle 10, the wire bundle 10 is connected to the corrugated tube 2 from the slit 22 of the corrugated tube 2 so that the noise suppressing member 13 is positioned inside the corrugated tube 2. Put inside. 16 and 17 are views showing a state in which the wire bundle 10 to which the two noise suppressing members 13 are attached is placed in the corrugated tube 2. Note that FIG. 17 shows the internal structure of the corrugated tube 2 in the structure shown in FIG. 16, and the corrugated tube 2 shows a cross-sectional structure in a plane perpendicular to the extending direction thereof.

In this modification, the diameter of the spherical main body 130 of the noise suppressing member 13 is set to be larger than the diameter of the annular concave surface 201 of the inner surface 200 of the corrugated tube 2 that stores nothing inside, for example. . Therefore, when the wire bundle 10 is inserted from the corrugated tube 2 so that the noise suppressing member 13 is positioned in the corrugated tube 2, as shown in FIG. 16, the corrugated tube 2 that stores nothing inside. Then, the closed slit 22 is opened.

As shown in FIG. 18, when the corrugated tube 2 is attached to the wire bundle 10, the slit 22 of the corrugated tube 2 is not opened after the wire harness having the wire bundle 10 and the corrugated tube 2 is routed to a vehicle or the like. The adhesive tape 500 is wound around the corrugated tube 2. At this time, the adhesive tape 500 is wound from end to end in the extending direction of the corrugated tube 2 with the opened slit 22 closed. Accordingly, as shown in FIG. 19, the main body 130 of the abnormal noise suppressing member 13 in the corrugated tube 2 is crushed by the inner surface 200 of the corrugated tube 2 to be plastically deformed, and is in close contact with the inner surface 200. Become. In the example of FIG. 19, the main body 130 is crushed and is in close contact with two annular concave surfaces 201 of the concave-convex inner surface 200 of the corrugated tube 2 and one annular convex surface 202 therebetween.

As described above, the main body portion 130 of the noise suppressing member 13 is brought into close contact with the inner surface 200 of the protective member 2 so that the main body 130 is crushed. Similarly to the case where the unevenness is fitted, it is possible to prevent the abnormal noise suppressing member 13 from being displaced in the protective member 2. Therefore, it is possible to further suppress the generation of abnormal noise from the inside of the protective member 2.

In addition, when the protection member 2 is a corrugated tube as in this example, the main body 130 is in close contact with the concave and convex inner surface of the corrugated tube, so that the noise suppressing member 13 is within the protection member 2. Misalignment can be further suppressed. Therefore, it is possible to further suppress the generation of abnormal noise from the inside of the protective member 2.

It should be noted that the shape of the main body 130 of the noise suppressing member 13 may be other than spherical. For example, the shape of the main body 130 may be a simple cylindrical shape.

Further, the noise suppressing member 3 shown in FIG. 1 may be formed of foamed polystyrene, as in the case of the noise suppressing member 13, or may be formed of a material other than synthetic rubber and foamed polystyrene. Moreover, the noise suppression member 13 may be formed of a synthetic rubber similarly to the noise suppression member 3, or may be formed of a material other than the synthetic rubber and the polystyrene foam.

Similarly to the main body portion 130 of the noise suppressing member 13, the shape of the main body portion 30 of the abnormal noise suppressing member 3 is set to be spherical or the like so that the main body portion 30 is crushed and the inner surface 200 of the protective member 2. It may be in close contact.

Moreover, when attaching the noise suppressing member 3 shown in FIG. 1 to the wire bundle 10, each of the plurality of electric wires 1 constituting the wire bundle 10 is the same as when attaching the noise suppressing member 13 to the wire bundle 10. May be pushed one by one from the slit 31 of the noise suppressing member 3 into the inside of the main body 30 of the noise suppressing member 3 (in the through hole 320).

Although the present invention has been described in detail, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
