{First embodiment}
Hereinafter, the wire harness 10 according to the first embodiment will be described. FIG. 1 is a schematic view showing the entire wire harness 10 according to the first embodiment. 2, 3, and 4 are a perspective view, a side view, and a front view showing a portion of the wire harness 10 according to the first embodiment where the vibration absorbing and fixing member 22 is provided.

  The wire harness 10 according to the present embodiment includes at least one electric wire 11 and two fixing members 20 and 21 having a vehicle fixing portion 40 for fixing the electric wire 11 to the vehicle. At least one of the two fixing members 20 and 21 is a vibration absorbing fixing member 22 including the vibration absorbing portion 30.

  Specifically, the electric wire 11 includes a plurality of electric wires bundled here, and is used as a wiring material that is routed in a vehicle or the like and electrically connects various electric components. The electric wire 11 may include an optical fiber cable or the like. Moreover, the electric wire 11 of FIGS. 1-9 has drawn the outline of the thing in which the some electric wire was bundled.

  The two fixing points to which the two fixing members 20 and 21 are fixed will be described here using the example of the engine 12 and the body 14, but may be a body and a frame. When the two fixing members are fixed at two places where the vibration conditions are the same, the case where the two fixing members are fixed at two places where the vibration conditions are different tends to increase the amplitude of the electric wire between them. It is good to fix to two places where conditions differ.

  Further, here, an example in which both the fixing member 20 fixed to the engine 12 and the fixing member 21 fixed to the body 14 are the vibration absorbing fixing member 22 provided with the vibration absorbing portion 30 will be described. At least one of them may be the vibration absorption fixing member 22. In addition, when it is provided in only one of them, the vibration amplitude of the electric wire 11 can be further suppressed when the vibration strength is higher, so that the engine 12 having a higher vibration strength is provided. It is desirable to be provided.

  In the wire harness 10 according to the present embodiment, as shown in FIG. 1, fixing members 16 and 17 having no vibration absorbing portion are provided so as to sandwich the fixing members 20 and 21 including the vibration absorbing portion 30. It is desirable that the wire harness 10 is fixed to the vehicle by the members 16 and 17. At this time, it is desirable that the fixing members 16 and 17 without the vibration absorbing portion are fixed to the same counterpart as the counterpart to which the fixing members 20 and 21 including the vibration absorbing portion 30 are fixed.

  Here, as the fixing member without the vibration absorbing portion, for example, a member in which the vibration absorbing portion 30 is not provided in FIG.

  Further, when only one of the fixing members 20 and 21 is the vibration absorbing fixing member 22 provided with the vibration absorbing portion 30, the fixing member that is not the vibration absorbing fixing member 22 among the fixing members 20 and 21. The electric wire 11 does not need to be further fixed by the fixing member 16 or the fixing member 17 with respect to the fixing partner to which is fixed.

  The vibration absorbing portion 30 is formed so as to cover the entire circumference in the circumferential direction of a part of the electric wires 11 in the longitudinal direction by an elastic sheet 32 formed of an elastic material such as foamed resin or rubber. And the vibration absorption part 30 is connected with the vehicle fixing | fixed part 40 by the outer peripheral side.

  More specifically, here, the vibration absorbing portion 30 is an electric wire having an elastic sheet 32 formed of foamed urethane in a sheet shape with an adhesive layer provided on one surface of the elastic sheet as the electric wire 11 side. 11 is formed by being wound around. If the elastic sheet 32 is formed of a foamed resin such as urethane foam, it is easy to form the elastic sheet 32.

  At this time, the thickness of the elastic sheet 32 is different depending on the type of elastic material to be used. However, if the elastic material of the same kind is used, the vibration of the electric wire 11 can be absorbed more as the thickness of the elastic sheet 32 increases.

  In addition, the width of the elastic sheet 32 is the same as or larger than the circumference of the electric wire 11 (in this case, larger) so that the entire circumference of the electric wire 11 can be covered in the circumferential direction of the electric wire 11. Is formed. In particular, when the thickness of the elastic sheet 32 is large, a difference in radius between the inner peripheral side and the outer peripheral side of the elastic sheet 32 wound around the electric wire 11 is increased due to the thickness, and thus the elastic sheet 32 is larger than the circumference of the electric wire 11. It is essential to do.

  Here, as the vehicle fixing portion 40, a clamp portion 42 formed of a so-called belt clamp is used. The clamp portion 42 includes an anchor portion 44 that is fixed to a fixed portion of the vehicle, and a plate-like fixing portion 46 that is integrally formed with the anchor portion 44. The clamp portion further includes a belt fixing portion 47 and a belt portion 48 provided on the plate-like fixing portion 46, and the belt portion 48 is wound around the vibration absorbing portion 30 (elastic sheet 32) and then the belt. By being fixed to the fixing portion 47, the vibration absorbing portion 30 is fixed to the plate-like fixing portion 46. Thereby, the vibration absorption part 30 and the vehicle fixing | fixed part 40 are connected in the outer peripheral side of the vibration absorption part 30. FIG.

  The length in the longitudinal direction of the electric wire 11 in the plate-like fixing portion 46 is formed to be the same as or shorter than the length of the elastic sheet 32, and the plate-like fixing portion 46 is provided as the vibration absorbing portion 30. It is desirable not to protrude in the longitudinal direction of the electric wire 11 than the elastic sheet 32 that is present. Thereby, it can suppress that the plate-shaped fixing | fixed part 46 damages the electric wire 11 by contacting the electric wire 11. FIG.

  Here, the belt portion 48 protrudes from one side surface of the plate-like fixing portion 46. The belt fixing portion 47 is provided with a hole penetrating from the side surface from which the belt portion 48 projects to the side surface opposite to the side surface. The vibration absorbing portion 30 is fixed to the plate-like fixing portion 46 by inserting and fixing the belt portion 48 wound around the vibration absorbing portion 30 into the hole from the front end side.

  However, as the clamp part 42, a clamp without the belt fixing part 47 and the belt part 48 may be used. In that case, instead of the plate-like fixing portion 46 provided with the belt fixing portion 47 and the belt portion 48, a plate-like fixing portion extended in the longitudinal direction of the electric wire 11 can be used. With the vibration absorbing part 30 in contact with the main surface of the plate-like fixing part, by winding the plate-like fixing part and the vibration absorbing part 30 at the same time with a tape or the like, with respect to the plate-like fixing part, The vibration absorbing unit 30 can be fixed. Hereinafter, a type of clamp fixed with a tape is referred to as a tape winding clamp with respect to a belt clamp fixed with a belt.

  Further, when the belt portion is wound around the vibration absorbing portion 30, the elastic sheet 32 of the vibration absorbing portion 30 is wound in a slightly reduced diameter state or in a natural length state (here, a slightly reduced diameter state). It has been turned.

  Although the fixing member 20 has been described here, it is assumed that the fixing member 21 is a vibration absorbing fixing member 22 similar to the fixing member 20. However, with respect to the fixing member 21, the material or size of the elastic sheet used for the fixing member 21 is changed according to the vibration of the body 14 to which the fixing member 21 is fixed. Things can be changed.

<Operation>
Next, the operation | movement which absorbs a vibration by the vibration absorption part 30 is demonstrated. The dotted line in FIG. 4 shows an example of the relative position of the electric wire 11 with respect to the fixing member 20 that is the vibration absorbing fixing member 22 when the electric wire 11 vibrates.

  First, the engine 12 and the body 14 which are counterparts to which the two fixing members 20 and 21 are fixed respectively vibrate under different vibration conditions (in general, the amplitude of the vibration of the engine 12 is the vibration of the body 14). Larger than the amplitude of). This vibration is transmitted in the order of the fixing members 20, 21, the respective vibration absorbing portions 30, and the electric wires 11.

  At this time, the fixing member 20 fixed to the engine 12 absorbs vibration when the elastic sheet 32 provided as the vibration absorbing portion 30 is elastically deformed, so that the vibration is attenuated and transmitted to the electric wire 11. To go. Thereby, compared with the case where the vibration absorption part 30 is not provided, since the amplitude of the electric wire 11 can be suppressed, the length of play required in order to prevent a disconnection can be shortened. For this reason, even when the distance between components is short, it can set to the length of play sufficient not to interfere with other members, and the electric wire 11 is not disconnected, and the disconnection of the electric wire 11 is suppressed. Is possible.

  In addition, when the fixing location fixed by the two fixing members 20 and 21 is a location with different vibration conditions, the two fixing members 20 and 21 vibrate differently. Thereby, since the distance between the two fixing members 20 and 21 varies, the distance may be larger than when stationary, and the electric wires 11 are moved to the opposite side by the two fixing members 20 and 21, respectively. Sometimes. For this reason, in the fixing members 20 and 21, a change in the relative position of the electric wire 11 (positional deviation) increases. If the vibration absorbing fixing member 22 is provided on a fixing member that is fixed at a location having different vibration conditions, the positional deviation of the electric wire 11 when vibrating can be suppressed, and the length of play can be set small.

  On the other hand, since the same vibration is transmitted from the engine to the two fixing members 16 and 20 between the fixing members 16 and 20 that are both fixed to the engine, the two fixing members 16 and 20 are similar to each other. Vibrate. Thereby, the distance between the two fixing members 16 and 20 is almost the same as when stationary, and the electric wires 11 always move in the same direction by the two fixing members 16 and 20. For this reason, the length of the original play between the fixing members 16 and 20 that are both fixed to the engine can be made smaller than the length of the play between the fixing members 20 and 21.

  For the same reason as described above, the original play length between the fixing members 17 and 21 fixed to the body can be made smaller than the play length between the fixing members 20 and 21.

  For this reason, the effect that the length of play can be made small becomes larger when the fixed part fixed by the two fixing members 20 and 21 is a part having different vibration conditions.

  Moreover, since it is difficult to predict the amplitude if the vibration conditions are different, it is difficult to set an appropriate play length. For this reason as well, it is more effective to provide the vibration absorbing portion 30 when the two fixing members 20 and 21 are respectively fixed at locations having different vibration conditions.

  Further, even when the vibration absorbing portion 30 is provided only on one of the fixing members, the vibration is absorbed by elastic deformation of the elastic sheet 32 on the side of the fixing member on which the vibration absorbing portion 30 is provided. Therefore, the vibration is transmitted to the electric wire 11 while being attenuated. Thereby, compared with the case where the vibration absorption part 30 is not provided, since the amplitude of the electric wire 11 can be suppressed, the length of play required in order to prevent a disconnection can be shortened. For this reason, even when the distance between components is short, it can set to the length of play sufficient not to interfere with other members, and the electric wire 11 is not disconnected, and the disconnection of the electric wire 11 is suppressed. Is possible.

  At this time, the vibration amplitude of the electric wire 11 is near the side where the vibration strength is fixed on the side where the vibration strength is high (here, the engine 12) and is fixed on the side where the vibration strength is low (here, the body 14). Bigger than. For this reason, the effect which suppresses the amplitude of the vibration of an electric wire by absorbing a vibration becomes large when the vibration absorption part 30 is provided in the fixing member fixed to the side with large vibration intensity | strength.

And a lid 52. By removing the lid portion 52 from the main body portion 51, the electric wire 11 can be accommodated in the protector portion 50, whereby the electric wire 11 can be protected.

  But the main-body part and a cover part are integrally formed, and may be formed so that opening and closing is possible with a hinge etc. That is, the protector part is good to be formed in the shape which is easy to accommodate the electric wire 11 inside.

  Moreover, the protector part 50 can be formed in three-dimensional shape, and the path | route control of the electric wire 11 can be performed by forming the curved part according to the wiring path | route of 10 A of wire harnesses.

  A fixing piece 54 is provided at one end of the protector 50 in the longitudinal direction of the electric wire 11. Here, the fixing piece 54 has a shape that protrudes in the longitudinal direction of the electric wire 11 from a portion of the end of the main body 51 of the protector 50 that is opposite to the lid 52. It has the same thickness as the portion 51. The fixed piece 54 is provided with a pair of main surfaces, and is in contact with the vibration absorbing portion 30 on one main surface.

  The binding member 56 wound around the fixing piece 54 and the vibration absorbing portion 30 is prevented from coming off at the end of the fixing piece 54 opposite to the end connected to the main body 51 of the protector 50. A tape stopper 55 which is a convex portion for forming the tape is formed. Specifically, the tape stopper 55 is configured so that the thickness of the fixed piece 54 slightly increases from the main surface of the fixed piece 54 that is not in contact with the vibration absorbing unit 30 toward the direction where the electric wire 11 is not provided. The convex part is formed.

  In the fixed piece 54, the fixed piece 54 and the vibration absorbing unit 30 are in contact with the vibration absorbing unit 30 wound around the electric wire 11 between the main body 51 of the protector unit 50 and the tape stopper 55. Are wound with a tape, so that the vibration absorbing portion 30 and the protector portion 50 are connected.

  In addition, although illustration is abbreviate | omitted here, the anchor part etc. are provided in the protector part 50 in order to fix to a vehicle. Thereby, the fixing member provided with the protector part 50 can be fixed to the vehicle.

<Operation>
In the vibration absorption fixing member 22 </ b> A of the wire harness 10 </ b> A according to the present embodiment, vibration from the engine is first transmitted to the protector unit 50, and then transmitted to the vibration absorption unit 30 and the electric wire 11.

  For this reason, also in the wire harness 10A according to the present embodiment, the vibration is attenuated because the elastic sheet 32 provided as the vibration absorbing portion 30 is elastically deformed to absorb the vibration, similarly to the first embodiment. While being transmitted to the electric wire 11. Thereby, compared with the case where the vibration absorption part 30 is not provided, since the amplitude of the electric wire 11 can be suppressed, the length of play required in order to prevent a disconnection can be shortened. For this reason, even when the distance between components is short, it can set to the length of play sufficient not to interfere with other members, and the electric wire 11 is not disconnected, and the disconnection of the electric wire 11 is suppressed. Is possible.

{Third embodiment}
A wire harness 10B according to a third embodiment will be described. 7 and 8 are a perspective view and a front view showing a portion where the vibration absorbing fixing member 22B is provided in the wire harness 10B according to the third embodiment. FIG. 9 is a diagram for explaining how the frame is opened and closed. In the description of the present embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The wire harness 10B according to the third embodiment is different from the vibration absorption fixing member 22 according to the first embodiment in that a vibration absorption fixing member 22B is provided, which is the same as the wire harness 10 according to the first embodiment. Different. Specifically, the vibration absorption fixing member 22B includes a cylindrical frame 60 and a vibration absorption unit 30B including at least three elastic members 62 that can be elastically deformed, instead of the vibration absorption unit 30 of the first embodiment. Is provided.

  Here, the frame body 60 is formed in a shape in which a square hole is provided from one surface to the other surface in a pair of opposing surfaces of a rectangular parallelepiped, but the hole cross section may be a circle. Alternatively, a hole may be formed in the cylinder. That is, the elastic member 62 can be disposed on the inner peripheral surface of the hole, and it is only necessary that the hole 11 is formed in a cylindrical shape through which the electric wire 11 can be inserted.

  The elastic member 62 protrudes from the inner peripheral surface of the frame body 60, holds the electric wire 11 at the end portion opposite to the end portion connected to the inner peripheral surface of the frame body 60, and ends at the frame body 60 side. Is formed so as to be elastically deformable in a direction connecting the wire and the end portion on the electric wire 11 side.

  More specifically, here, the elastic member 62 protrudes from the four inner peripheral surfaces of the quadrangular holes formed in the frame body 60 toward the opposing surfaces, and the four elastic members 62 are provided. It has been. Each elastic member 62 is formed in a cylindrical shape in which a bottom surface is a rhombus prism and a hole is formed from one side to the other side of both bottom surfaces, and one of sides (side ridges) connecting corresponding vertices of both bottom surfaces. It is connected with the frame 60 on one side ridge side.

  The electric wire 11 is clamped on the side ridges of the four elastic members 62 opposite to the side ridges connected to the frame body 60. But the electric wire 11 may be fixed with respect to the elastic member 62, but if it is clamped, the effort to fix can be saved.

  In a state where the electric wire 11 is held by the elastic member 62 and in a stationary state, the central axis of the electric wire 11 is on a line connecting the side ridge on the frame body 60 side of the elastic member 62 and the side ridge on the opposite side. It is desirable to be. As a result, the elastic force of the elastic member 62 can be used to more reliably attenuate the vibration.

  Further, in a state where the electric wire 11 is held by the elastic member 62 and in a stationary state, when the frame body 60 and the elastic member 62 are cut by a surface passing through the central axis of the electric wire 11 and parallel to the gravity direction, Desirably, the frame 60 and the elastic member 62 are formed symmetrically. As a result, the elastic force of the elastic member 62 can be used to more reliably attenuate the vibration.

  Here, the frame body 60 includes a hinge portion 64 and a lock portion 66. More specifically, the hinge part 64 is provided in one part of the circumferential direction. Further, the frame body 60 is cut along the longitudinal direction of the electric wire 11 at a portion different from the portion where the hinge portion 64 is provided in the circumferential direction so that the frame body 60 can be opened and closed via the hinge portion 64. ing. The lock part 66 is provided so that the closed state of the frame body 60 can be maintained.

  As the hinge part 64, in order to hold the electric wire 11 between the four elastic members 62, an open state in which the frame body 60 is opened so that the electric wire 11 can be inserted into the inside from the opening, and a closed state in which the opening is closed Any hinge can be used as long as it can be opened and closed between the two. Further, when the frame body 60 is made of resin, the hinge portion 64 can be provided with a hinge function by making the hinge portion 64 thinner than the periphery.

  The lock portion 66 only needs to be capable of maintaining the closed state of the frame body 60. Here, a protrusion is provided on the outer peripheral side of the one side frame body 60 with the cut surface as a boundary, and the other side frame body On the outer peripheral side of 60, a projection is inserted, and an insertion recess that can be locked after insertion is provided.

It can be anywhere if possible. However, when the frame 60 is opened and the electric wire 11 is inserted, it is easier to insert the wire 60 as far as possible in the outer peripheral direction of the frame 60.

  However, it is not essential that the hinge portion 64 and the lock portion 66 are provided. However, by providing the hinge portion 64, the electric wire 11 can be inserted into the inside from the openings in order to cause the electric wire 11 to be held between the four elastic members 62, so that the electric wire 11 is easily held in the elastic member 62. Further, by providing the lock portion 66, the closed state of the frame body 60 can be maintained.

  On the outer peripheral surface of the frame 60, an anchor portion 69 is provided here as a vehicle fixing portion 40B in a portion where the hinge portion 64 and the cut surface are not provided. The anchor portion 69 can be the same as the anchor portion 44 provided in the clamp portion 42 of the first embodiment.

<Operation>
In the portion of the vibration absorption fixing member 22B of the wire harness 10B according to the present embodiment, the engine vibration is first transmitted from the vehicle fixing portion 40B to the frame body 60 in the vibration absorption portion 30B, and then the elastic member 62, the electric wire It will be transmitted to 11. In the wire harness 10B according to the present embodiment, vibration is absorbed by elastic deformation of the elastic member 62, so that the vibration is transmitted to the electric wire 11 while being attenuated. Thereby, since the amplitude of the electric wire 11 can be suppressed compared with the case where the vibration absorption part 30B is not provided, the length of play necessary to prevent disconnection can be shortened. For this reason, even when the distance between components is short, it can set to the length of play sufficient not to interfere with other members, and the electric wire 11 is not disconnected, and the disconnection of the electric wire 11 is suppressed. Is possible.

{Modification}
In the third embodiment, the vibration absorption fixing member 22B includes a protector as a vehicle fixing portion, and includes a frame body 60 and an elastic member 62 according to the third embodiment at the end of the protector in the longitudinal direction of the electric wire 11. A vibration absorbing portion 30B may be formed. At this time, if the protector is provided with a vehicle fixing member, the frame body 60 may not be provided with the anchor portion 69.

  Further, in the third embodiment, instead of the anchor portion 69, the vibration absorption fixing member 22B includes a belt clamp or a tape winding clamp as a vehicle fixing portion, and the belt clamp around the frame body 60 of the vibration absorption portion 30B. The vehicle fixing part and the vibration absorbing part may be connected by being wound with a belt or a tape.

<Effect>
According to the wire harness according to each embodiment, at least one of the two fixing members 20 and 21 is a vibration absorbing fixing member including a vibration absorbing portion, so that vibration is absorbed. Even if the length of play is shortened so that interference can be suppressed, even if the length of play is shortened, it is possible to make it difficult for the electric wire to be disconnected.

  In particular, according to the wire harness according to the first or second embodiment, the vibration absorbing unit 30 is formed by the elastic sheet 32 so as to cover the entire circumference in the circumferential direction of the electric wire 11, and therefore vibrates in all directions. It can absorb, and vibration absorption part 30 can be formed easily. Moreover, since the elastic sheet 32 that forms the vibration absorbing portion 30 is formed of foamed resin, the elastic sheet 32 can be easily formed.

  In particular, according to the wire harness 10 according to the first embodiment, since the clamp portion is provided, it can be fixed to the fixing counterpart by the clamp portion.

  In particular, according to the wire harness 10 </ b> A according to the second embodiment, since the protector unit 50 is provided, the electric wire 11 can be protected or route-regulated.

  In particular, according to the wire harness 10B according to the third embodiment, since the electric wire 11 is sandwiched by at least three elastic members 62 connected to the frame body 60, the vibration is absorbed in all directions of the electric wire 11. Can do.

  In addition, since the frame body 60 can be opened and closed via the hinge portion 64, the electric wire 11 can be easily held in the frame body 60, whereby the electric wire 11 can be easily held by the elastic member 62. Moreover, after the electric wire 11 is clamped and the frame body 60 is closed, the closed state can be maintained by the lock portion 66.

  In addition, when a vibration absorption part is provided in two fixing members, what combined said each embodiment may be sufficient. For example, the vibration absorbing fixing member 22 according to the first embodiment is used as the fixing member 20 fixed to the engine 12, and the vibration absorbing fixing member according to the third embodiment is used as the fixing member fixed to the body 14. 22B may be used.

  Moreover, each structure demonstrated by said each embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, 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.
