  The present invention relates to a technique for protecting an electric wire.

  A protection member for protecting an electric wire included in the wire harness from its peripheral members may be attached to the wire harness in a vehicle or the like.

  As the protective member, a molded protector, a corrugated tube, or the like, which is a resin molded product, is used. Patent Document 1 discloses a molding protector, and Patent Document 2 discloses a corrugated tube.

Japanese Patent Laid-Open No. 08-154324 JP 2014-7850 A

  However, since the molding protector is a resin molded product, it is necessary to start a separate mold for each path of various wire harnesses and mold the molding protector. For this reason, the manufacturing cost tends to increase.

  Moreover, since a corrugated tube is easy to bend, it is unsuitable for the use which carries out path | route control of a wire harness.

  Therefore, a technique has been proposed in which a hollow plate material is bent into a cylindrical shape that can accommodate a wire harness to form a protective member.

  However, for example, in order to keep the hollow plate material in a cylindrical shape, some configuration for maintaining the both side portions in a connected state is required. For example, in the structure which joins the both sides of a hollow board material by an adhesive agent or welding, there exists a problem that processing cost becomes high.

  Then, when forming the protection member of an electric wire with a hollow plate material, this invention aims at enabling it to connect at low cost as much as possible.

  In order to solve the above-mentioned problem, the first aspect is an accommodation shape in which a hollow plate material in which a hollow structure is formed between at least one electric wire and a plurality of plate-like portions can accommodate the at least one electric wire.

  A third aspect is an electric wire module according to the first or second aspect, wherein the protection member includes a bottom part, a pair of side wall parts erected on both side parts of the bottom part, and The first lid portion extending from one of the pair of side wall portions to the other and a second lid portion extending from the other of the pair of side wall portions to the other are bent. The first lid portion includes the first overlapping portion, and the second lid portion includes the second overlapping portion overlapping the first overlapping portion.

  A 4th aspect is an electric wire module which concerns on a 3rd aspect, Comprising: The said 1st cover part and the said 2nd cover part overlap with each between the said pair of side wall parts as a whole.

  The fifth aspect is a protective member capable of accommodating at least one electric wire, and a hollow plate material in which a hollow structure is formed between a plurality of plate-like portions accommodates the at least one electric wire. The protection member is configured to be bent into a shape, and includes a first overlapping portion and a second overlapping portion that are overlapped in the state of being bent into the accommodating shape, and the first overlapping portion includes the first overlapping portion and the second overlapping portion.

Can be overlapped with each other through the first slit and the second slit, so that the first overlapped portion and the second overlapped portion can be overlapped with each other. When forming the hollow plate members, the portions of the hollow plate members can be connected as low as possible.

  According to the second aspect, the portion of the first overlapped portion divided by the first slit enters between the plurality of interposition portions of the second overlapped portion via the second slit, and the second overlapped portion Of these, the portion divided by the second slit enters between the plurality of intervening portions of the first overlapped portion via the first slit. Thereby, a 1st overlapping part and a 2nd overlapping part can be maintained more reliably in the overlapping state.

  Hereinafter, the electric wire module and the protection member according to the embodiment will be described.

  FIG. 1 is a schematic perspective view showing the electric wire module 10, and FIG. 2 is a schematic perspective view showing a state before the electric wire module 10 is completed. 3 is a partial front view of FIG. 1, and FIG. 4 is a partial front view of FIG. FIG. 5 is a schematic perspective view showing an example of the hollow plate member 50 constituting the protective member.

  The electric wire module 10 includes at least one electric wire 14 and a protection member 20.

  The electric wire 14 is configured by extruding an insulation coating or the like around the conductive wire. Here, the electric wire module 10 includes an electric wire bundle 12 in which a plurality of electric wires 14 are bundled. The wire bundle 12 may be branched at an intermediate portion in the extending direction of the protection member 20 or outside.

  As will be described below, the protective member 20 is formed by bending a hollow plate member 50 in which a hollow structure is formed between a plurality of plate-like portions 52 into an accommodation shape capable of accommodating the at least one electric wire 14. It is configured.

  Here, an example of the hollow plate member 50 will be described with reference to FIG.

  The hollow plate member 50 includes a plurality (two in this case) of plate-like portions 52 and an interposed portion 54 sandwiched between the plurality of plate-like portions 52. Here, the hollow plate member 50 includes a plurality of interposition portions 54 interposed in parallel between the plurality of plate-like portions 52.

  The plate-like portion 52 is formed in a flat plate shape. A plurality of plate-like portions 52 are connected via an intervening portion 54 with a space therebetween.

  The plurality of interposition parts 54 are arranged in parallel between the two plate-like parts 52 with a space therebetween. Each interposed portion 54 is formed in an elongated plate shape, and is disposed in a vertical posture with respect to the two plate-like portions 52. One side portion of each interposition portion 54 is connected to one plate-like portion 52, and the other side portion is connected to another one plate-like portion 52. Thereby, the two plate-like portions 52 and the plurality of interposition portions 54 are integrally connected so as to exhibit a ladder-like cross section in a plane orthogonal to the extending direction of the interposition portions 54.

  In addition, the material which forms the several plate-shaped part 52 and the interposition part 54 is not specifically limited. The plurality of plate-like portions 52 and the intervening portions 54 may be formed of paper, may be formed of resin, or may be configured by a combination thereof. When at least one of the plurality of plate-like portions 52 and the intervening portion 54 is formed of paper, it is preferable to perform a water repellent treatment or the like on the surface.

  When the hollow plate material 50 is molded from a resin, for example, the hollow plate material 50 can be continuously produced by an extrusion molding apparatus that extrudes resin from an extrusion hole corresponding to the ladder-shaped cross section. Thus, the hollow plate member 50 can be easily manufactured at low cost. The interposition part 54 may be connected to the plate-like part 52 by an adhesive or welding.

  According to such a hollow plate member 50, the plurality of plate-like portions 52 are connected by the interposition portions 54 at intervals, and thus are difficult to bend. Further, since the interposition portion 54 is interposed between the plate-like portions 52, the hollow plate material 50 is also reinforced by the interposition portion 54 so that it is difficult to bend and dent. In particular, in this example, the hollow plate member 50 can be made difficult to bend in the extending direction of the interposition part 54.

  Therefore, by manufacturing the protection member 20 with the hollow plate member 50, the electric wire 14 can be sufficiently protected and the path can be sufficiently restricted. Further, since a hollow structure is formed between the plurality of plate-like portions 52 of the hollow plate member 50, the weight can be reduced and the material cost can be reduced accordingly.

  Note that an electromagnetic shield member such as a metal foil (aluminum foil) may be provided on at least a part of the hollow plate member 50 described above.

  Moreover, when each hollow plate material includes three or more plate-like portions, it is preferable that an intervening portion is provided between each. Thereby, the intensity | strength of a hollow plate material can be improved more.

  The protection member 20 is formed by bending the hollow plate member 50.

  Here, the protection member 20 includes a bottom portion 22, a pair of side wall portions 24, a first lid portion 26, and a second lid portion 28.

  The bottom 22 is formed in an elongated plate-like portion. The pair of side wall portions 24 are formed in an elongated plate shape, and are erected so as to protrude from both side portions of the bottom portion 22 to one main surface side of the bottom portion 22. The wire bundle 12 is accommodated in a space surrounded by the bottom portion 22 and the pair of side wall portions 24.

  The first lid portion 26 and the second lid portion 28 are formed in an elongated plate shape. The first lid part 26 is formed so as to extend from one side wall part 24 toward the other side wall part 24. The second lid portion 28 is formed so as to extend from the other side wall portion 24 toward the one side wall portion 24.

  That is, the hollow plate material 50 before forming the protection member 20 is formed in a square shape, and the hollow plate material 50 is bent at a plurality of linear folds arranged in parallel at intervals. The bottom portion 22, the pair of side wall portions, the first lid portion 26, and the second lid portion 28 are formed in the shape described above.

  In addition, the protection member 20 has comprised the square cylinder shape in the completion form. Here, although the protection member 20 is extended linearly, you may bend in the middle. As a configuration for bending the protective member, for example, a configuration in which a bellows structure is formed in an intermediate portion in the extending direction, or an intermediate portion in the extending direction of the protective member is cut and bent except for a part around the outer periphery. A configuration or the like can be adopted. Moreover, the opening for branching a part of inner wire bundle and guiding it outward may be formed in the extending direction intermediate part of the protection member.

  Further, here, the first lid portion 26 and the second lid portion 28 are formed in an elongated plate shape having the same width as the bottom portion 22, and each of the openings between the tip portions of the pair of side wall portions 24 is formed in the width direction. It is formed in a shape that can be closed throughout. And the 1st cover part 26 and the 2nd cover part 28 are comprised so that it may overlap between each whole between the front-end | tip parts of a pair of side wall part 24. As shown in FIG. Here, the first lid portion 26 is disposed over the entire end portion of the pair of side wall portions 24, and the second lid portion 28 covers the entire outside of the first lid portion 26. It is superimposed on the part 26.

  In addition, the protection member 20 includes a first overlapping portion and a second overlapping portion that are overlapped in the state of being bent into the accommodation shape. In the present embodiment, the first lid portion 26 includes a first overlapping portion, and the second lid portion 28 includes a second overlapping portion. More specifically, in the present embodiment, the entire first lid portion 26 is a first overlapping portion, and the entire second lid portion 28 is a second overlapping portion.

  A first slit 26 </ b> S is formed in a portion on the second lid portion 28 side of the first lid portion 26, that is, an outer plate-like portion 52. Here, between the plurality of interposition portions 54 in the outer plate-like portion 52, more specifically, at the center position of the plurality of interposition portions 54, the plurality of first portions along the extending direction of the interposition portions 54. A slit 26S is formed. Here, the first slit 26 </ b> S is formed between the interposed portions 54 in the entire width direction of the first lid portion 26.

  In the first lid portion 26, the plurality of interposition portions 54 are maintained in a parallel state via the inner plate-like portion 52. In addition, an elongated plate-like piece 52p formed by the outer plate-like portion 52 being divided by the first slit 26S remains in the outer portion of the plurality of interposed portions 54, and each of the interposed portions 54 and the elongated portions is formed. The plate-like piece 52p has a T-shaped cross-sectional shape that is wide on the second lid portion 28 side (outside).

  In addition, a second slit 28 </ b> S is formed in a portion on the first lid portion 26 side of the second lid portion 28, that is, an inner plate-like portion 52. Here, between the plurality of interposition portions 54 of the inner plate-like portion 52, more specifically, at a central position of the plurality of interposition portions 54, a plurality of second portions along the extending direction of the interposition portions 54. A slit 28S is formed. Here, the second slit 28 </ b> S is formed between the interposition portions 54 in the entire width direction of the second lid portion 28.

  In the second lid portion 28, the plurality of interposition portions 54 are maintained in a parallel state via the outer plate-like portion 52. In addition, the elongated plate-like piece 52q formed by dividing the inner plate-like portion 52 by the second slit 28S remains in the inner portion of the plurality of intervening portions 54. Each interposed portion 54 and the elongated plate-like piece 52q have a T-shaped cross-sectional shape that is wide on the first lid portion 26 side (inner side).

  The first slit 26S and the second slit 28S can be formed by a punching blade or the like that can cut the hollow plate member 50 halfway in the thickness direction. When the hollow plate material is punched, it is preferable to form the first slit 26S and the second slit 28S together.

  Then, the pair of side wall portions 24 are bent with respect to the bottom portion 22, and further, the first lid portion 26 and the second lid portion 28 are bent from the distal end portions of the pair of side wall portions 24, The second lid portion 28 is overlapped. At this time, the first lid portion 26 and the second lid portion 28 are overlapped so that the plurality of intervening portions 54 are alternately arranged (see FIG. 4).

  In this state, when a force F is applied in the direction in which the first lid portion 26 and the second lid portion are brought into contact with each other, the elongated plate-like pieces 52p of the respective interposition portions 54 of the first lid portion 26 are moved to the second lid portion 28. The inner plate-like portion 52 is pressed against the portion where the second slit 28S is formed. Then, both side portions of the elongated plate-like piece 52p of the first lid portion 26 are elastically deformed toward the proximal end side of the interposition portion 54, and both sides of the second slit 28S in the plate-like portion 52 inside the second lid portion 28. The part is elastically deformed so as to be spread. Thereby, the front-end | tip part of each interposition part 54 of the 1st cover part 26 and the part of the elongate plate-shaped piece 52p enter the hollow structure through the 2nd slit 28S of the 2nd cover part 28. FIG.

  Similarly, the elongated plate-like piece 52q of each intervening portion 54 of the second lid portion 28 is pressed against the portion of the plate-like portion 52 outside the first lid portion 26 where the first slit 26S is formed. Then, both side portions of the elongated plate-like piece 52q of the second lid portion 28 are elastically deformed toward the proximal end side of the interposition portion 54, and both sides of the first slit 26S in the plate-like portion 52 outside the first lid portion 26. The part is elastically deformed so as to be spread. Thereby, the front-end | tip part of each interposition part 54 of the 2nd cover part 28 and the part of the elongate plate-shaped piece 52q enter into the hollow structure through the 1st slit 26S of the 1st cover part 26. FIG.

  In this state, the interposition portions 54 on the first lid portion 26 side and the interposition portions 54 on the second lid portion 28 side are alternately arranged, and the elongated plate-like pieces 52p and 52q face each other on the inner surfaces. Thus, they are locked together, that is, locked together in the retaining direction. Thereby, the 1st cover part 26 and the 2nd cover part 28 are maintained in the state overlapped.

  By maintaining the first lid portion 26 and the second lid portion 28 in a superposed state as described above, with the wire bundle 12 accommodated between the bottom portion 22 and the pair of side wall portions 24, The electric wire module 10 is completed.

  According to the electric wire module 10 configured as described above, since the electric wire bundle 12 is accommodated in the protection member 20, the electric wire bundle 12 is externally attached (for example, the edge of a member around the wiring path of the electric wire bundle 12. The wire bundle 12 can be restricted along a predetermined wiring path. Moreover, the electric wire bundle 12 can also be maintained in a shape (here, a square shape) corresponding to the route space in the wiring route.

  In particular, since the protection member 20 is formed by bending the hollow plate material into a shape that can accommodate the wire bundle 12, it can be configured to be lightweight. Further, since a versatile hollow plate material can be bent and appropriately formed into a shape suitable for accommodating the wire bundle 12, cost reduction can be achieved.

  Further, in the form before assembling the hollow plate 50 into the shape of a protective member that can accommodate the electric wires 14, that is, in the form in which the hollow plate 50 is punched into a predetermined shape and the first slit 26S and the second slit 28S are formed, a flat plate Because of its shape, it has the advantage that it can be stored and transported in a space-saving manner.

  Further, the first slit 26S is formed in the first lid portion 26 that is the first overlapping portion of the hollow plate member 50, and the second slit 28S is formed in the second lid portion 28 that is the second overlapping portion, and these By allowing the first lid portion 26 and the second lid portion 28 to enter each other's hollow structure via the first slit 26S and the second slit 28S, the first lid portion 26 and the second lid portion 28 are provided. Therefore, when the protective member 20 of the electric wire 14 is formed by the hollow plate member 50, the portions of the hollow plate member 50 can be connected as low as possible.

  In particular, as compared with the case where the hollow plate material is welded or bonded with an adhesive, a welding facility is not required, or the cost can be reduced in that an adhesive is not required.

  Further, for example, in a configuration in which a slit penetrating the front and back is formed in one side portion of the hollow plate material and a claw portion that can be inserted into and inserted into the slit is formed in the other side portion, It is necessary to cut out the part into a complicated shape, and restrictions on the layout become large in order to secure the cutout part of the claw part. However, in this embodiment, since it is only necessary to form slits in the overlapping portions, layout restrictions can be reduced, and the through punching shape can be simplified.

  In the present embodiment, the hollow plate member 50 is configured to include a plurality of plate-like portions 52 and a plurality of interposition portions 54 interposed in parallel between the plurality of plate-like portions 52, and the first overlap. In the first lid portion 26 that is a portion, the first slit 26S is formed between the plurality of interposition portions 54 with respect to the plate-like portion 52 on the second lid portion 28 side, and is a second overlapping portion. In the lid portion 28, the second slit 28 </ b> S is formed between the plurality of interposition portions 54 with respect to the plate-like portion 52 on the first lid portion 26 side. Therefore, the first slit 26 </ b> S in the first lid portion 26. The elongated plate-like piece 52p, which is a portion divided by the first portion, enters between the plurality of intervening portions 54 of the second lid portion 28 via the second slit 28S, and is divided by the second slit 28S of the second lid portion 28. The elongated plate-like piece 52q, which is the portion that has been formed, has a first slip. Through 26S, enters between the plurality of intervening portion 54 of the first lid portion 26. Thereby, the overlapping state of the 1st cover part 26 and the 2nd cover part 28 can be maintained more reliably.

  But the structure of the hollow plate material 50 is not restricted to the said example, For example, the structure by which a some plate-shaped part is maintained at intervals by the interposition part which interposes in the shape of a dot between them may be sufficient. Even in this case, by forming a slit in the overlapping portion of the hollow plate material, it is possible to enter each other's hollow structure through the slit.

  Here, the first overlap portion is the first lid portion 26, and the second overlap portion is the second lid portion 28. Therefore, the first lid portion 26 and the second lid portion 28 are overlapped. By combining them, it is possible to maintain a state in which the hollow plate member 50 is closed in a square tube shape, that is, a shape in which the hollow plate member 50 can accommodate the electric wires 14.

  Moreover, since the 1st cover part 26 and the 2nd cover part 28 have overlapped entirely, protection performance can be improved in the part. For this reason, when the electric wire module 10 is assembled and then installed in the vehicle, the overlapping portion of the first lid portion 26 and the second lid portion 28 is the bottom side, that is, an attachment component (for example, a floor) Etc). Thereby, the abrasion resistance by interference with the protection member 20 and the other party components in a vehicle can be improved.

  In addition, it is not essential that the 1st cover part and the 2nd cover part have overlapped entirely. For example, the 1st cover part may extend over the whole between a pair of side wall parts, and the 2nd cover part may extend to the middle in between a pair of side wall parts. In this case, it is only necessary to form the slit only in the first lid portion where the second lid portion overlaps.

  It should be noted that the above-described structure for maintaining the overlapping state of the hollow plate members can be applied to a portion other than the overlapping portion of the first lid portion and the second lid portion.

  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.
