The entrance to the space can be opened, and the wire harness can be inserted into the wire harness insertion space as it is. After the wire harness is inserted, the entrance to the wire harness insertion space is closed by restoring the side wall bent outward, so that the wire harness is inserted into the wire harness insertion space first during the wire harness insertion operation. It is possible to prevent the wire harness from jumping out. Therefore, even when a wire harness is manufactured by inserting each wire into the wire harness insertion space one by one, it is possible to prevent the wire inserted earlier during the insertion operation from jumping out, and to increase the productivity of the wire harness. Can do.

  According to the wire harness holding clip configured as described in (2) above, when an electric wire is inserted into the wire harness insertion space one by one, the electric wire to be pulled out is caught in the slit of the auxiliary holding portion, and it becomes more difficult to pull out.

Can also be eliminated. In addition, for example, when the wire bundle is covered with a hard resin protective layer, the fixing force between the resin material and the electric wire increases, so the difference in expansion coefficient between the electric wire and the resin material during curing after molding. As a result, excessive stress is applied to the resin material and the electric wire, and in the worst case, the resin material may be damaged or the electric wire may be disconnected, but when foam is molded outside the wire bundle, , Because the adhesive force can be kept low by generating a slip between the electric wire and the foam, it is possible to absorb the expansion difference generated between the materials during curing, damage the molded body due to the difference in thermal expansion and the electric wire It is possible to prevent the occurrence of problems such as disconnection.

Therefore, it is not necessary to retrofit the wire harness holding clip, and productivity can be improved. Also, by supporting the electric wire bundle with the wire harness holding portion of the wire harness holding clip, the electric wire bundle can be arranged at the center of the cross section of the resin protective layer, so that the resin can be applied to the entire circumference of the electric wire bundle. It can be spread out and the exposed part of the wire bundle can be eliminated. Therefore, the wire bundle can be reliably protected from interference with external parts, and the protection performance can be improved. In addition, since the wire harness holding part of the wire harness holding clip is only embedded, the resin protective layer is not interrupted at that part and the gap is not opened, so the rigidity of the wire harness can be enhanced by continuation of the resin protective layer. As a result, it is possible to reduce the number of places to be clamped and to improve the assemblability when the wire harness is assembled to the vehicle body.

Between the anchor protrusion 2a and the wire harness holding part 2c, a foot part 2b for securing the height of the wire harness holding part 2c is provided.

  In this case, the wire harness holding portion 2c includes a bottom wall 2d fixed directly on the foot portion 2b, and a pair of side walls 2e and 2f extending upward from both ends in the width direction of the bottom wall 2d. . The pair of side walls 2e and 2f together with the bottom wall 2d define a wire harness insertion space 2g and, as shown in order in FIGS. 2 (a) to 2 (c), wire harnesses (electric wires and wire bundles) W from above. By pressing, it bends and deforms outward to open the entrance to the wire harness insertion space 2g, thereby enabling the wire harness W to be inserted into the wire harness insertion space 2g. In addition, after the wire harness W is inserted, the tips 2er and 2fr are overlapped with each other so that the wire harness W is curved inward toward the tip so as to close the entrance to the wire harness insertion space 2g.

  In other words, the side walls 2e and 2f are protruded inward from the curved portions 2ec and 2fc, and the ends 2er and 2fr slightly overlap each other. Then, on the upper side of the overlapping portion, when the wire harness W is pressed from above, a recess 2h (see FIG. 1) for ensuring that the side walls 2e and 2f are bent outward is secured.

  According to the wire harness holding clip 2, the side walls 2e and 2f are bent outward by pressing the wire harness W from above on the overlapping portion of the ends 2er and 2fr of the pair of side walls 2e and 2f curved inward. In addition, the entrance to the wire harness insertion space 2g can be opened, and the wire harness W can be inserted into the wire harness insertion space 2g as it is. Then, after the insertion of the wire harness W, the side walls 2e and 2f bent outward are restored inward to close the entrance of the wire harness insertion space 2g. It is possible to prevent the wire harness W inserted in the wire harness insertion space 2g from jumping out. Accordingly, even when a wire harness is manufactured by inserting each wire into the wire harness insertion space 2g one by one, it is possible to prevent the wire inserted earlier during the insertion operation from jumping out and increase the productivity of the wire harness. be able to.

  Next, the wire harness of embodiment using this wire harness holding clip 2 is demonstrated.

  The wire harness WH (FIG. 8) of this embodiment is provided with the resin protective layer 1 (FIG. 8) on the outer periphery of a wire bundle (a bundle of many covered wires) so as to cover the entire circumference of the wire bundle. Furthermore, the wire harness holding clip 2 for fixing the wire harness WH to the vehicle body panel is formed integrally with the resin protective layer 1. Specifically, the foot portion 2b of the wire harness holding clip 2 and the wire harness holding portion 2c are embedded in the resin protective layer 1 by insert molding, and the anchor protrusion 2a at the base of the wire harness holding clip 2 is It protrudes outside the resin protective layer 1. And the electric wire bundle is arrange | positioned in the center part of the cross section of the resin protective layer 1 by hold | maintaining the electric wire bundle in the wire harness holding part 2c of the wire harness holding clip 2. FIG.

  Moreover, the resin protective layer 1 in this case is configured by a foam (hereinafter, the foam may be denoted by reference numeral 1) molded so as to cover the entire outer periphery of the wire bundle. In particular, the foam 1 is foam-molded by a bead method, and is made of, for example, a bead-method polystyrene foam. The beaded polystyrene foam is made by pre-foaming raw material beads made of polystyrene resin and a hydrocarbon-based foaming agent, and then filling the mold and heating. In addition to the bead method polystyrene foam, a bead method polyurethane foam, a bead method polypropylene foam, or the like can be used instead.

  Next, the manufacturing method of the wire harness WH of embodiment is demonstrated using FIGS.

  First, as shown in FIG. 3, the lower mold 11 is set on the wiring jig plate 10 provided with the wiring jig 12, and the wire harness holding clip 2 (not shown) is disposed inside the lower mold 11. To do. When installing the wire harness holding clip 2, as shown in FIG. 1, the wire harness holding clip 2 is formed on the bottom wall of the cavity of the lower mold (molding mold) 11 for molding the resin protective layer (foam) 1 in advance. A holding hole 11a having a shape corresponding to the anchor projection 2a at the base of the wire harness is provided, and the anchor projection 2a at the base of the wire harness holding clip 2 is fitted into the holding hole 11a, thereby supporting the wire harness holding clip 2. At the same time, the wire harness holding portion 2c of the wire harness holding clip 2 is exposed to the inside of the cavity.

  Then, as shown in FIGS. 4 and 5, the sub-wire harnesses W1 and W2 (wire bundle W) are sequentially placed on the wire harness holding portion 2c (not shown in FIGS. 4 and 5) of the wire harness holding clip 2. The sub-wire harnesses W1 and W2 are routed on the routing jig plate 10 in a state where the range in which the resin protective layer 1 is provided is housed in the lower mold 11 while being placed on the sub-wire harness W1, W2 (electric wire bundle W) is held by the wire harness holding portion 2c as shown in FIG. At this time, as shown in FIG. 2A, the electric wire bundle W (sub-wire harnesses W1 and W2) is overlapped with the side walls 2e and 2f of the wire harness holding clip 2 as shown by an arrow A from above. By pressing on the part, the side walls 2e and 2f can be pushed outward as indicated by the arrow B in FIG. 2B, and the wire bundle W (sub-wire harnesses W1 and W2) is inserted into the wire harness insertion space 2g as it is. can do.

  By doing so, as shown in FIG. 1, a certain gap H can be secured between the wire bundle W (sub-wire harnesses W1, W2) and the bottom wall of the cavity of the lower mold 11, thereby Between the outer periphery of the wire bundle W and the inner wall of the cavity, a resin filling gap over the entire circumference of the wire bundle W can be secured. That is, the wire bundle W can be supported by the clip 2 in a state of floating in the cavity. The size of the gap H can be determined by adjusting the height of the foot 2b of the wire harness holding clip 2.

  When the electric wire bundle W (sub-wire harnesses W1 and W2) is routed, the upper die 13 is placed on the lower die 11 and the upper die 13 and the lower die 11 are clamped as shown in FIG. When the mold is clamped, as shown in FIG. 7, the molding material 20 is filled into a cavity (not shown) formed by the lower mold 11 and the upper mold 13. Here, the raw material beads subjected to primary foaming are filled. After filling, steam is introduced into the cavity and heated as necessary. Once heated and foamed, cure and cool. When the cooling is completed, the upper mold 13 is removed and the molded foam (resin protective layer) 1 is removed from the lower mold 11 as shown in FIG. Thereby, while the required location of the wire bundle W is covered with the foam (resin protective layer) 1, the wire harness WH of embodiment which integrated the wire harness holding clip 2 (refer FIG. 1) is obtained.

  According to the wire harness WH manufactured in this way, since the wire harness holding clip 2 is integrated with the resin protective layer 1 at the stage of molding the resin protective layer 1, the wire harness holding clip 2 needs to be retrofitted. Productivity can be improved.

  Moreover, since the wire bundle W is arranged at the center of the cross section of the resin protective layer 1 by supporting the wire bundle W with the wire harness holding portion 2c of the wire harness holding clip 2, the resin protective layer 1 is molded. Sometimes, the resin can be spread over the entire circumference of the wire bundle W, and the exposed portion of the wire bundle W can be eliminated. Therefore, the wire bundle W can be reliably protected from interference with external parts, and the protection performance can be improved.

  Further, since the wire harness holding portion 2c of the wire harness holding clip 2 is merely embedded, the resin protective layer 1 is not interrupted at that portion and a gap is not opened. Therefore, the wire harness WH by continuous resin protective layer 1 is provided. The rigidity can be increased (the holding strength of the self-shape can be increased), the number of places to be clamped can be reduced, and the assemblability when the wire harness WH is assembled to the vehicle body can be improved.

  In this case, since the outer side of the wire bundle W is covered with the foam (resin protective layer) 1 having a buffering property, it is possible to eliminate the occurrence of wear and noise due to interference with peripheral parts and interference between wires. In addition, for example, when the wire bundle is covered with a hard resin protective layer, the fixing force between the resin material and the electric wire increases, so the difference in expansion coefficient between the electric wire and the resin material during curing after molding. As a result, excessive stress is applied to the resin material and the electric wire, and in the worst case, the resin material may be damaged or the electric wire may be disconnected, but the foam 1 is molded on the outside of the electric wire bundle W. In this case, since the sliding force can be generated between the wire bundle W and the foam 1 to suppress the adhesion force low, the difference in expansion generated between the materials during curing can be absorbed, and the molding based on the difference in thermal expansion. It is possible to prevent the occurrence of problems such as body damage and wire breakage.

  In particular, when the foam 1 is foam-molded by a bead method (a foaming method in which beads having a size of primary expanded rice grains are spread in a mold and heated to perform secondary foaming), the wire bundle W This makes it difficult for the foam 1 to enter the complicated and fine irregularities on the outer surface of the film, and the amount of fixing can be further reduced.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  For example, in the above embodiment, the materials of the lower mold 11 and the upper mold 13 which are the molds are not particularly mentioned, but a mold, a resin mold, and a wooden mold can be used as the mold material. . In addition, as a material for the wire harness holding clip 2, polypropylene, polystyrene, polyurethane, or the like can be selected. In this case, the wire harness holding clip 2 needs to be previously formed. In addition to the injection molding method, an injection molding method or a compression molding method can be selected for the molding method of the foam 1.

  Next, a wire harness holding clip according to another embodiment will be described. FIG. 9 is an external perspective view of the wire harness holding clip of the second embodiment.

  The wire harness holding clip 20 includes an anchor projection 21 for fixing to a vehicle body or the like at a base portion, and has a wire harness holding portion 23 on the anchor projection 21. Between the anchor protrusion 21 and the wire harness holding portion 23, a foot portion 22 for securing the height of the wire harness holding portion 23 is provided.

  In this case, the wire harness holding portion 23 includes a bottom wall 23d fixed directly on the foot portion 22 and a pair of side walls 23e and 23f extending upward from both ends in the width direction of the bottom wall 23d. . The pair of side walls 23e and 23f together with the bottom wall 23d define a wire harness insertion space 23g and bend outwardly by pressing the wire harness from above to open the entrance to the wire harness insertion space 23g. The wire harness W can be inserted into the wire harness insertion space 23g. Further, after the wire harness is inserted, the tips 23er and 23fr are overlapped with each other so that the wire harness is curved inward toward the tip so as to close the entrance to the wire harness insertion space 23g.

  In other words, the side walls 23e and 23f are protruded inward from the curved portions 23ec and 23fc, and the ends 23er and 23fr slightly overlap each other. Then, on the upper side of the overlapping part, when the wire harness is pressed from above, a recess 23h is ensured to bend the both side walls 23e, 23f to the outside reliably.

  In addition, the auxiliary holding portion 25 extends from the both side walls 23e and 23f on one end side of the wire harness holding portion 23 of the wire harness holding clip 20 of this embodiment (that is, one end side in the direction in which the wire harness penetrates). Is provided. The auxiliary holding part 25 has a plurality of strips by inserting a cut along the penetration direction of the wire harness from the front end to the base end in an extension wall having the same cross-sectional shape as the side walls 23e, 23f extending from the side walls 23e, 23f. And a slit 25b having a width corresponding to the thickness of the electric wire is formed between adjacent narrow pieces 25a.

  In this way, when a large number of narrow pieces 25a and slits 25b are alternately arranged in a bowl shape, each narrow piece 25a can individually exhibit flexibility, so that an electric wire is inserted into the wire harness insertion space 23g. When it does, the electric wire which is going to come out is caught in the slit 25b, and it becomes difficult to go out. Therefore, an auxiliary electric wire holding function can be exhibited.

  The wire harness holding clip 30 of the third embodiment shown in FIG. 10 is provided on both the one end side and the other end side of the wire harness holding portion 23 (that is, both ends in the direction in which the wire harness penetrates) from both side walls 23e and 23f.
