  In recent automobiles, the number of in-vehicle electrical components has increased with the increase in functionality, the number of wires required for wiring has increased, and wiring has become complicated, such as having many branch portions. In addition, with the diversification of vehicle types, it is necessary to cope with wire harnesses of a large number of specifications in which the position of the above-described branching portion is different.

  As the number of electric wires increases, wire harnesses for instrument panels (instrument panel wire harnesses) in which a large number of electrical components are concentrated are especially provided in order to reduce the weight of automobiles and reduce environmental impact. ), It has been proposed to make the wires thinner. However, while there is a limit to reducing the weight by reducing the diameter of the wire, the wire becomes thinner and the rigidity of the wire harness is reduced, making it difficult to maintain the shape, and it is easy to hang down with its own weight. There is no denying that the installation work is even more difficult.

  In this regard, the configuration of Patent Document 1 requires a special cross-sectional shape reinforcement having a recess, which greatly increases the cost. In addition, the shape of the wire harness can be surely retained after being attached to the recess of the reinforcement, but the wire harness easily bends before being attached to the recess, so the problem of improving the workability of wiring It cannot be said that it was solved satisfactorily.

  Moreover, since the protector is divided in the configuration of Patent Document 2, the number of parts increases. Moreover, since it is necessary to provide a tongue piece, a to-be-latched hole, etc. in order to couple | segment a division-shaped protector, each protector will become a complicated shape and cost will increase.

  Furthermore, since Patent Document 2 is configured to fix the protector to the reinforcement by inserting and locking the clip portion into the attachment hole, it is necessary to align the position of the clip portion of the protector to the attachment hole where the reinforcement is small. In addition, the operator was forced to perform a difficult task of adjusting the insertion position in a narrow space inside the panel. Further, once the protector is attached to the reinforcement, it is difficult to remove the protector, and the workability when the wire harness needs to be repaired or replaced is reduced. Furthermore, since the length of each divided protector is fixed, it is not possible to flexibly cope with various wire harnesses having different branch positions, and there is still room for improvement in this respect.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a wire harness shape holding member that facilitates the mounting work of the wire harness and can be manufactured at a low cost with a small number of components. .

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to the 1st viewpoint of this invention, the wire harness shape holding member of the following structures is provided. That is, the wire harness shape holding member includes an outer shell portion and a fixing portion.

In the fixed portion, a pair of elastically deformable arms for grasping the reinforcement from outside is provided. The arm is formed integrally with the outer shell portion.

  Thereby, the wire harness can be attached to the reinforcement while the shape of the wire harness that is easily bent is held by the outer shell portion, so that the assembly workability is good. Moreover, since the wire harness shape holding member is fixed by the arm of the fixing portion gripping the reinforcement from the outside, the wire harness shape holding member can be easily attached to the reinforcement without special processing. Furthermore, since the arm of the fixed part is formed integrally with the outer shell part, a simple structure that can effectively reduce the number of parts can be realized. Further, since the elastic deformation of the arm is used at the time of fixing, even if it is necessary to remove the arm for the repair after the wire harness is attached, it can be easily removed by elastically deforming the arm again.

  In the said wire harness shape holding member, it is preferable that the said outer shell part is formed with the open part which opens the said accommodation space over the whole longitudinal direction of the said outer shell part.

  Thereby, the trunk line part of a wire harness can be easily accommodated in an outer shell part. Moreover, since a branch line part can be pulled out from the arbitrary positions of an open part, it can respond to a wide variety of wire harnesses.

  In the wire harness shape holding member, a hooking rib for fixing a cover member that closes a part of the open portion is formed in the outer shell portion in parallel with the longitudinal direction of the outer shell portion. It is preferable.

  Thereby, various cover members can be easily attached to the outer shell, and can be used for the wiring work of the wire harness.

  The wire harness shape holding member preferably has the following configuration. That is, in the fixing portion, an opening is formed between the ends of the arms provided in pairs. The direction of the opening is opposite to the direction of the opening.

  Thereby, the direction in which the wire harness shape holding member is attached to the reinforcement and the direction in which the branch line portion of the wire harness is pulled out from the accommodation space are opposite to each other. Therefore, when attaching the wire harness shape holding member to the reinforcement, the branch line portion is not easily obstructed, so that the assembling workability can be further improved.

  In the wire harness shape holding member, it is preferable that a protrusion is provided between the root portions of the arms provided in pairs in the fixing portion.

  Thereby, the movement of the fixing part attached to the reinforcement is prevented by the protrusion. Therefore, the wire harness shape holding member and the wire harness can be reliably fixed to the reinforcement.

  The wire harness shape holding member preferably has the following configuration. That is, a plurality of the fixing portions are provided at intervals in the longitudinal direction of the outer shell portion. The protrusions are provided only on some of the fixed portions of the plurality of fixed portions.

  As a result, by omitting the configuration for positioning the fixing portion at the less important place, the configuration of the wire harness shape holding member can be simplified, and at the same time, the cost and man-hour for processing the reinforcement can be suppressed. it can.

  The wire harness shape holding member preferably has the following configuration. That is, a rib is formed on the arm in the fixed portion. The rib is connected to the wall surface of the outer shell portion to which the base portion of the arm is connected, and is also connected to a wall surface perpendicular to the wall surface.

  Thereby, the intensity | strength of an arm and an outer shell part can be raised effectively.

  The wire harness shape holding member preferably has the following configuration. That is, the wire harness is an instrument panel wire harness. The reinforcement is instrument panel reinforcement.

  That is, in the instrument panel wire harness, a thin electric wire may be used, and the wire harness is particularly loose. In this regard, according to the above configuration, the wire harness is accommodated in the outer shell portion to increase the rigidity to maintain the shape and improve the assembling workability. Therefore, the present invention makes the instrument panel wire harness an instrument panel reinforcement. It is particularly suitable for mounting.

  According to the 2nd viewpoint of this invention, the wire harness with a shape holding member of the following structures is provided. That is, this wire harness with a shape holding member includes the wire harness shape holding member and the wire harness. The said wire harness is accommodated in the accommodation space of the said outer shell part.

  As a result, the wire harness can be attached to the reinforcement while the shape of the wire harness that is easily bent is held by the outer shell portion, so that the assembly workability is good. Moreover, since the wire harness shape holding member is fixed by the arm of the fixing portion gripping the reinforcement from the outside, the wire harness shape holding member can be easily attached to the reinforcement without special processing. Furthermore, since the arm of the fixed part is formed integrally with the outer shell part, a simple structure that can effectively reduce the number of parts can be realized. Further, since the elastic deformation of the arm is used at the time of fixing, even if it is necessary to remove the arm for the repair after the wire harness is attached, it can be easily removed by elastically deforming the arm again.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic perspective view showing a wire harness shape holding member 1 of the present embodiment. FIG. 2 is a perspective view showing the wire harness 3 and the reinforcement 2. FIG. 3 is an enlarged view of the wire harness shape holding member 1 as seen in the longitudinal direction of the outer shell portion 4.

  The wire harness shape holding member 1 of the present embodiment shown in FIG. 1 is used for routing the wire harness 3 along the reinforcement 2 shown in FIG. As shown in FIG. 1, the wire harness shape holding member 1 includes an elongate outer shell portion 4 and two (plural) gripping portions (fixing portions) 5.

  As shown in FIG. 3, the outer shell portion 4 includes a flat plate-like first plate portion 41, a flat plate-like second plate portion 42 that is perpendicularly connected to one end of the first plate portion 41, and a first plate portion 41. And a flat plate-like third plate portion 43 that is connected perpendicularly to the other end. Therefore, the cross section obtained by cutting the outer shell portion 4 perpendicularly to the longitudinal direction has a shape in which the gate is inverted as shown in FIG. 3 when the first plate portion 41 is viewed downward.

  In the outer shell portion 4, a portion surrounded by these three plate portions 41 to 43 is an accommodation space 44. Further, the side opposite to the first plate portion 41 (the side without the plate portion, the upper side) is an open portion 45 that opens the accommodation space 44.

  The outer shell portion 4 is formed in an elongated shape in a straight line while having the above-described cross section uniformly, and as a result, as shown in FIG. The space 44 is elongated. Moreover, the opening part 45 that opens the accommodation space 44 is also provided linearly over the entire longitudinal direction of the outer shell part 4. Therefore, by inserting the trunk portion 31 of the wire harness 3 from the open portion 45 and arranging the trunk portion 31 in the accommodating space 44, the outer shell portion 4 can cover the trunk portion 31 over a certain length.

  As described above, the outer shell portion 4 has a shape in which the three plate portions 41 to 43 are vertically connected. Therefore, the outer shell portion 4 has good rigidity in combination with ensuring the thickness of the plate portions 41 to 43 as appropriate. Can be obtained. Therefore, by arranging the wire harness 3 in the housing space 44 of the outer shell portion 4, the shape of the wire harness 3 can be maintained so that the wire harness 3 is not easily deformed by its own weight or the like.

  In the present embodiment, as shown in FIG. 2, the wire harness 3 branches from the trunk portion 31 serving as the main harness while two (plural) branch lines 32 and 32 form branch portions 33 and 33, respectively. It has become the composition. When the trunk portion 31 is accommodated in the accommodation space 44, the branch line portion 32 is arranged so as to be pulled out from the opening portion 45. Thus, the open part 45 has a function not only as an insertion port of the main line part 31 but also as a drawing place of the branch line part 32.

  In addition, since the opening part 45 is provided over the whole longitudinal direction of the outer shell part 4 (similar to the said accommodation space 44), the branch line part 32 can be pulled out from the arbitrary site | parts of the opening part 45. FIG. Accordingly, it is possible to flexibly accommodate various wire harnesses 3 in which the number of branch line portions 32 and the position of the branch portion 33 are different.

  Further, since the cross section of the outer shell 4 cut perpendicularly to the longitudinal direction is uniform as described above, the direction in which the opening 45 opens the accommodation space 44 is constant in any part of the outer shell 4 ( In the present embodiment, the upper side). As a result, since the two branch lines 32 and 32 can be guided so as to be drawn out in the same direction, the routing workability of the branch lines 32 can be improved.

  Next, the grip part 5 will be described. The plurality of gripping portions 5 have the same shape, and are integrally formed with the outer shell portion 4 by synthetic resin.

  As shown in FIGS. 1 and 3, the grip portion 5 is formed in a C shape such that a part of a short cylinder is cut out, thereby forming a shape having two arc-shaped arms 54 and 54. Has been. An opening 55 is formed between the distal ends of the two arms 54 and 54. The direction of the opening 55 is arranged opposite to the direction of the opening portion 45 in the outer shell portion 4.

  The two arms 54 and 54 are configured to be elastically deformed to some extent, and are deformed by applying an external force in the direction of expanding the opening 55, while returning to the original shape when the external force is released. ing. In addition, an inclined guide surface 56 is formed at the tip of each arm 54, 54, so that the opening 55 gradually expands from the inside to the outside of the grip portion 5. It has become.

  On the outside of each arm 54, 54, a rib 57 is integrally formed along the shape of the arm 54. Thereby, the rigidity of the grip part 5 is increased to some extent.

  As shown in FIG. 1 and the like, each of the plurality of gripping portions 5 is formed such that the axial direction of the short cylindrical gripping portion 5 with a part cut away is parallel to the longitudinal direction of the outer shell portion 4. ing. Thus, since the direction of the some holding | gripping part 5 is arrange | equalized, the wire harness shape holding member 1 (wire harness 3) is easily attached to the elongated reinforcement 2 using the plurality of holding parts 5. be able to.

  Next, the wiring work to the reinforcement 2 of the wire harness 3 using the wire harness shape holding member 1 of this embodiment is demonstrated with reference to FIGS. FIG. 4 is a perspective view showing a state in which the wire harness 3 is housed in the outer shell portion 4. FIG. 5 is a perspective view showing how the wire harness 3 with the wire harness shape holding member 1 is fixed to the reinforcement 2.

  First, as shown in FIG. 4, the operator inserts the trunk portion 31 of the wire harness 3 from the open portion 45 of the outer shell portion 4 and arranges it in the accommodation space 44. Thereby, since the shape of the wire harness 3 is linearly held by the outer shell portion 4, the subsequent handling of the wire harness 3 is simplified.

  Subsequently, the operator winds the adhesive tape 12 around the outer shell portion 4 and the wire harness 3 as shown in FIG. Thereby, it can fix so that the wire harness 3 may not remove | deviate from the outer shell part 4 (wire harness shape holding member 1).

  In addition, the place which winds the adhesive tape 12 is not restricted to the position shown in FIG. 5, but can be suitably changed according to circumstances. For example, the pressure-sensitive adhesive tape 12 may be wound around the entirety of the other portions, leaving the grip portion 5 and the branch portion 33. By the above, the wire harness 3 and the wire harness shape holding member 1 can be integrated (modularized).

  Note that the wire harness 3 with the wire harness shape holding member 1 may be delivered to the automobile manufacturer after the above-described operation described with reference to FIG.

  Thereafter, the operator is formed on the two gripping portions 5 as shown by the arrows in FIG. 5 with the wire harness shape holding member 1 facing so that the opening portion 45 is up and the gripping portion 5 is down. The opening 55 is applied to the reinforcement 2 and pushed in with force. Then, since the reinforcement 2 pushes the inclined guide surfaces 56, 56 wide, the two arms 54, 54 are elastically deformed so as to widen the opening 55, and the reinforcement 2 is inserted into the grip portion 5. When the entire reinforcement 2 enters the inside of the grip portion 5, the elastic deformation of the arms 54, 54 is released and the reinforcement 2 is sandwiched so as to be gripped from the outside. Thereby, the wire harness 3 can be fixed to the reinforcement 2 together with the wire harness shape holding member 1.

  In addition, the wire harness shape holding member 1 of this embodiment differs from the above-mentioned patent document 2 by the point mounted | worn so that the outer periphery of the reinforcement 2 may be gripped using the elastic deformation of the holding part 5 as mentioned above. Yes. With this structure, the wire harness shape holding member 1 can be easily removed by pulling in a direction away from the reinforcement 2. Therefore, even if the wire harness 3 needs to be repaired or replaced, it can be easily handled.

  As described above, the wire harness shape holding member 1 of the present embodiment includes the outer shell portion 4 and the grip portion 5. The outer shell portion 4 is formed in an elongated shape so as to have an accommodation space 44 through which the wire harness 3 passes. The grip portion 5 can be fixed to the reinforcement 2. In the grip part 5, elastically deformable arms 54 and 54 for gripping the reinforcement 2 from the outside are provided in pairs. The arms 54 and 54 are formed integrally with the outer shell 4.

  Thereby, since the said wire harness 3 can be attached to the reinforcement 2 while hold | maintaining the shape of the wire harness 3 which is easy to be bent with the outer shell part 4, the assembly | attachment workability | operativity is favorable. In addition, since the wire harness shape holding member 1 is fixed by the arms 54 and 54 of the grip portion 5 holding the reinforcement 2 from the outside, the wire harness shape holding member 1 can be easily obtained without special processing of the reinforcement 2. It can be attached to Reinforce 2. Furthermore, since the arms 54 and 54 of the grip part 5 are formed integrally with the outer shell part 4, a simple structure that can effectively reduce the number of parts can be realized. In addition, since the elastic deformation of the grip portion 5 is used, even when it is necessary to remove the wire harness 3 for repair, for example, after the wire harness 3 is attached, the grip portion 5 can be easily removed by elastically deforming it again. .

  Further, in the wire harness shape holding member 1 of the present embodiment, the outer shell portion 4 is formed with an open portion 45 that opens the accommodation space 44 over the entire longitudinal direction of the outer shell portion 4.

  Thereby, the trunk line part 31 of the wire harness 3 can be easily accommodated in the outer shell part 4. Moreover, since the branch line part 32 can be pulled out from the arbitrary positions of the open part 45, it can respond to a wide variety of wire harnesses 3.

  Further, in the wire harness shape holding member 1 of the present embodiment, an opening 55 is formed between the tips of the arms 54 and 54 provided in pairs in the grip portion 5. The direction of the opening 55 is opposite to the direction of the opening 45.

  Thereby, the direction in which the wire harness shape holding member 1 is attached to the reinforcement 2 and the direction in which the branch line portion 32 of the wire harness 3 is pulled out from the accommodation space 44 are opposite to each other. Therefore, when attaching the wire harness shape holding member 1 to the reinforcement 2, the branch line portion 32 is not easily obstructed, so that the assembly workability can be further improved.

  Moreover, in this embodiment, the wire harness 3 is an instrument panel wire harness and the reinforcement 2 is an instrument panel reinforcement.

  That is, in the instrument panel wire harness, a thin electric wire may be used, and the wire harness is particularly loose. In this respect, according to the above-described configuration, the wire harness 3 is accommodated in the outer shell portion 4 so that the rigidity is increased and the shape can be maintained and the assembling workability can be improved. It is particularly suitable for attachment to a reinforcement.

  Next, a first modification of the above embodiment will be described. FIG. 6 is an enlarged view showing a modified wire harness shape holding member 1 p having a positioning protrusion 61 and the reinforcement 2. FIG. 7 is a perspective view showing a state where the wire harness 3 to which the modified wire harness shape holding member 1p is attached is fixed to the reinforcement 2. FIG. In the following description, the same or similar members as those of the above-described embodiment are denoted by the same reference numerals in the drawings, and description thereof may be omitted.

  In the wire harness shape holding member 1p of the first modification shown in FIG. 6, a positioning protrusion (protrusion) 61 is formed between the roots of the two arms 54 and 54 in the grip portion 5. The positioning projection 61 is integrally formed on the outer surface of the first plate portion 41 constituting the outer shell portion 4 and protrudes toward the opening 55 side.

  On the other hand, in the reinforcement 2, a positioning hole 2a having a shape corresponding to the positioning protrusion 61 is formed.

  As shown in FIG. 7, the wire harness shape holding member 1p has a configuration in which three gripping portions 5 are integrally formed. Of the three gripping portions 5, the positioning protrusions 61 are provided in two of the three gripping portions 5 located at both ends in the longitudinal direction of the outer shell portion 4. On the other hand, the positioning protrusion 61 is not provided on the grip portion 5 located at the center in the longitudinal direction. Along with this, two positioning holes 2 a formed in the reinforcement 2 are formed so as to correspond to the positioning protrusions 61 at both ends.

  In this configuration, when the wire harness shape holding member 1p is attached to the reinforcement 2 as shown in FIG. 7, the positioning protrusion 61 enters the positioning hole 2a so that the grip portion 5 does not move in the longitudinal direction of the reinforcement 2. In addition, it can be regulated not to rotate around the reinforcement 2 as an axis. Therefore, the routing workability is further improved.

  In FIG. 7, the positioning protrusions 61 are provided only at the two gripping portions 5 because the wire harness shape holding member 1 and the reinforcement 2 are both formed in a straight line, so that they are positioned at two locations. This is because it can be sufficiently fixed if possible. For this reason, in this modification, the positioning protrusion 61 and the positioning hole 2a are omitted from the grip portion 5 located at the center, thereby simplifying the configuration and reducing the processing cost. However, depending on the circumstances, the central gripping portion 5 may be provided with the positioning protrusions 61 to have the three positioning protrusions 61.

  As described above, in the wire harness shape holding member 1p of the present modification, the positioning protrusion 61 is provided between the root portions of the arms 54 provided in pairs in the grip portion 5.

  Thereby, the movement of the grip 5 attached to the reinforcement 2 is blocked by the positioning protrusion 61. Therefore, the wire harness shape holding member 1p and the wire harness 3 can be reliably fixed to the reinforcement 2.

  Further, in the wire harness shape holding member 1p of the present modification, a plurality of gripping portions 5 are provided at intervals in the longitudinal direction of the outer shell portion 4. The positioning protrusions 61 are provided only on some gripping portions 5 among the plurality of gripping portions 5.

  As a result, the configuration for the wire harness shape holding member 1p can be simplified by omitting the configuration for positioning the grip portion 5 at a less important place, and at the same time, the cost and man-hour for processing the reinforcement 2 are suppressed. can do.

  Next, a second modification of the above embodiment will be described. FIG. 8 is an enlarged view showing a wire harness shape holding member 1q according to a modified example in which the shape of the rib 57 is changed.

  In the wire harness shape holding member 1q of the second modified example shown in FIG. 8, the ribs 57 formed on the respective arms 54, 54 are extended, not only the first plate portion 41 of the outer shell portion 4, The second plate portion 42 or the third plate portion 43 that is vertically connected to the end portion is integrally coupled. Thereby, since the intensity | strength of the base part of the arm 54 can be increased effectively, damage can be prevented. Further, the rib 57 can increase the rigidity of the outer shell portion 4.

  As described above, in the wire harness shape holding member 1q of the present modification, the arm 54 is formed with the rib 57, and this rib 57 is the outer shell portion 4 to which the root portion of the arm 54 is connected. In addition to being connected to the wall surface (first plate portion 41), it is also connected to a wall surface (second plate portion 42 or third plate portion 43) perpendicular to the wall surface.

  Thereby, the intensity | strength of the arm 54 and the outer shell part 4 can be raised effectively.

  Next, with reference to FIG.9 and FIG.10, the modification regarding the outer shell part 4 is demonstrated.

  That is, like the wire harness shape holding member 1r in FIG. 9, the fourth plate portion 48 is provided so as to be connected perpendicularly to the end portion of the second plate portion 42, while the third plate portion 43 is slightly shortened, A shape in which one of the four corners of the rectangle is cut out may be used. In this case, the opening part 45 faces diagonally upward.

  Moreover, like the wire harness shape holding member 1 s of FIG. 10, a gentle curve is formed between the first plate portion 41 and the second plate portion 42 and between the first plate portion 41 and the third plate portion 43. It can also be formed to connect.

  Next, with reference to FIG. 11, the modification regarding the holding part 5 is demonstrated.

  That is, like the wire harness shape holding member 1t of FIG. 11, the grip portion 5 (two arms 54, 54) can be provided over the entire length of the outer shell portion 4. In this wire harness shape holding member 1t, the arm 54 is not provided with a rib.

  The wire harness shape holding member 1t of the present modification has a uniform cross section throughout the entire length direction. Therefore, since the wire harness shape holding member 1t can be manufactured by extrusion molding of a synthetic resin, the cost can be reduced. Moreover, since the wire harness shape holding member 1t having a desired length can be easily obtained by cutting the extrusion-molded product with an arbitrary length, the wire harness and the reinforcement having various configurations can be obtained while suppressing the cost. Can respond.

  Next, a second embodiment of the present invention will be described. FIG. 12 is an enlarged view of the wire harness shape holding member 1 u and the reinforcement 2 according to the second embodiment when viewed in the longitudinal direction of the outer shell portion 4.

  The wire harness shape holding member 1u according to the second embodiment shown in FIG. 12 is mainly different from the first embodiment in the shape of the outer shell 4.

  Details will be described below. In the wire harness shape holding member 1u, the second plate portion 42 and the third plate portion 43 constituting the outer shell portion 4 are formed to be lower in height than the first embodiment shown in FIG. As a result, when the wire harness 3 (main line portion 31) is accommodated in the accommodation space 44, the upper portion of the wire harness 3 is greatly exposed from the open portion 45 of the outer shell portion 4.

  On the upper portions of the second plate portion 42 and the third plate portion 43, hook ribs 67, 67 projecting outward are formed. In addition, stopper ribs 68 and 68 projecting outward are formed on the second plate portion 42 and the third plate portion 43, respectively. The hook rib 67 and the stopper rib 68 are provided over the entire longitudinal direction of the outer shell portion 4.

  By using these hooking ribs 67, a tape stopper member 80 and a branching portion support member 90 described later can be fixed to the outer shell portion 4.

  Further, in the wire harness shape holding member 1 u, a positioning protrusion 61 is formed between the root portions of the two arms 54 and 54 in the grip portion 5. The positioning protrusion 61 has the same configuration as the positioning protrusion 61 in the modification described with reference to FIG. 6, and can be positioned by being inserted into the positioning hole 2 a formed in advance in the reinforcement 2.
