  Hereinafter, the slit mounting member mounting jig, the wire harness manufacturing method, and the slit mounting member according to the embodiment will be described.

  FIG. 1 is a schematic view showing a wire harness 10, and FIG. 2 is a schematic cross-sectional view taken along the line II-II of FIG.

  The wire harness 10 includes a wire harness main body 12, a corrugated tube 20, and a path maintaining member 30 as a slit mounting member.

  The wire harness main body 12 is configured by binding a plurality of electric wires. More specifically, the wire harness main body 12 has a configuration in which a plurality of electric wires are bundled while being branched according to a wiring form to a vehicle to be arranged. The wire harness main body 12 does not necessarily have to be branched. The wire harness main body 12 may be configured by a single electric wire. Further, another optical cable or the like may be bound to the wire harness main body 12.

  When the wire harness main body 12 is disposed in a vehicle or the like, the wire harness main body 12 is bent along the arrangement form. In order to suppress the wire harness main body 12 from interfering with the peripheral portion, etc., the wire harness main body 12 may be maintained in a shape along the wiring form. In such a case, the path maintaining member 30 is attached to the wire harness main body 12 together with the corrugated tube 20 to maintain the wire harness main body 12 in a certain shape. In addition, the part by which the corrugated tube 20 and the path | route maintenance member 30 are mounted | worn with respect to the wire harness main-body part 12 should just be at least one part of the wire harness main-body part 12, and is a part of the wire harness main-body part 12. Or almost the whole.

  The corrugated tube 20 is a cylindrical member in which annular convex portions and annular concave portions are alternately formed along the longitudinal direction, and is formed of a resin or the like. Since the corrugated tube 20 is easily elastically deformed at a step portion between the annular convex portion and the annular concave portion, the corrugated tube 20 itself has a property of being easily bent and deformed as a whole. Usually, as the corrugated tube 20, what has an internal diameter larger than the outer diameter of the part of the wire harness main-body part 12 used as mounting | wearing object is used.

  Moreover, the slit 24 is formed in the one side part of the corrugated tube 20 along the longitudinal direction (refer FIG. 2). Then, the wire harness main body 12 can be easily disposed in the corrugated tube 20 by being split open by the slit 24.

  The path maintenance member 30 is a long member that maintains the wire harness body 12 and the corrugated tube 20 in a shape along a predetermined path.

  Here, the path | route maintenance member 30 is formed in the fixed shape according to the arrangement | positioning path | route in which the part used as mounting | wearing object is arrange | positioned among the wire harness main-body parts 12 at the time of metal mold | die shaping | molding. In this case, the path maintaining member 30 is a P.M. P. It is preferable to mold using a resin having a certain degree of rigidity, such as (polypropylene). The path maintaining member 30 may be linear in the entire longitudinal direction or may be bent. When the path maintaining member 30 is bent, it may be bent in the entire longitudinal direction, or may be bent only in a part of the longitudinal direction.

  The path maintaining member 30 is configured to be attachable to the corrugated tube 20 along its longitudinal direction. That is, the path maintaining member 30 includes a portion of the corrugated tube 20 in which a pair of concave groove portions 36g capable of accommodating the edge portions on both sides of the slit 24 are formed. In other words, the path maintaining member 30 is provided with the outer peripheral projection 32 on the one side (outer peripheral side) edge of the elongated connecting part 31 and the other side (inner peripheral side) edge of the connecting part 31. The inner peripheral projection 33 is provided with a cross-sectional shape in a plane perpendicular to the longitudinal direction thereof, which is substantially H-shaped. The outer surface of the outer peripheral projection 32 has an arcuate curved surface that protrudes outward. The width dimension of the recessed groove part 36g is set to a dimension that is substantially the same as or larger than (slightly larger than) the thickness dimension of the corrugated tube 20.

  The part of the path maintaining member 30 where the pair of concave groove portions 36g is formed may be the entire longitudinal direction of the path maintaining member 30 or a part along the longitudinal direction. In the present embodiment, an example in which the pair of concave groove portions 36g is formed over the entire longitudinal direction of the path maintaining member 30 will be described.

  Moreover, the recessed part 38 is formed in the outer peripheral part of the edge part of the path | route maintenance member 30 (refer FIG. 1). Here, the recessed part 38 is formed in the both sides | surfaces of the edge part of the connection part 31, and is formed in the recessed shape of the rectangular parallelepiped surface shape opened toward outward, respectively. Of the recess 38, the surface 38 a on the side of the connecting portion 31, that is, the surface 38 a facing the intermediate portion in the longitudinal direction of the path maintaining member 30 moves the fixing portion 59 a described later to the end side of the path maintaining member 30. It is set as the fixed surface 38a to suppress (see FIG. 6). Then, in a state where each of a pair of fixing portions 59a to be described later is fitted into the pair of recesses 38, the path maintaining member 30 is prevented from moving toward the middle portion in the longitudinal direction by contacting the fixing surface 38a. The ends of the path maintaining member 30 are fixed by the pair of fixing portions 59a.

  The path maintaining member 30 is disposed in the slit 24 of the corrugated tube 20 in a state where the wire harness main body 12 is disposed in the corrugated tube 20. In this state, both side edges sandwiching the slit 24 in the corrugated tube 20 are fitted into the pair of concave grooves 36g. In this manner, the wire harness main body 12 and the corrugated tube 20 are integrated with the path maintaining member 30 in a state bent along the shape of the path maintaining member 30.

  Thereafter, if necessary, a tie band, an adhesive tape or the like is wound around the outer periphery of the corrugated tube 20 so that the closed state of the corrugated tube 20 is maintained, and the corrugated tube 20 and the path maintaining member 30 are integrated. Is maintained.

  The path maintaining member may be a member that is plastically deformable and exhibits rigidity that maintains the wire harness main body and the corrugated tube in a shape along a predetermined path after plastic deformation. For example, the outer shape portion of the path maintaining member 30 may be molded with an elastomer such as rubber, and a shape maintaining line may be embedded in the inside along the longitudinal direction. As the path maintaining member, a metal wire such as an iron wire, a copper wire, a stainless steel wire, or an alloy wire thereof, or a resin that exhibits a certain degree of rigidity after plastic deformation can be used.

  In addition, here, a description will be given of the path maintaining member 30 that maintains the path of the wire harness body 12 as the slit mounting member, but the slit mounting member does not necessarily need to maintain the path of the wire harness body 12. For example, the slit mounting member is formed of an elastic material such as an elastomer (rubber or the like) and does not maintain the path of the wire harness main body 12, but is mounted on the slit 24 and closes the slit 24 in the same manner as described above. It may be configured as a member.

  The operation | work which arrange | positions the said path | route maintenance member 30 over a long length with respect to the slit 24 of the corrugated tube 20 becomes a very difficult operation | work. In particular, when the path maintaining member 30 is used for the purpose of maintaining the wire harness 10 in a bent shape, the path maintaining member 30 itself is formed in a shape bent in various modes. Also from this point, the operation of inserting the path maintaining member 30 into the slit 24 becomes difficult.

  The slit mounting member mounting jig of the present embodiment is a jig for easily mounting the path maintaining member 30 to the slit 24 of the corrugated tube 20.

  3 is a schematic perspective view showing the slit mounting member mounting jig 50, FIG. 4 is a partial perspective view of the slit mounting member mounting jig 50, and FIG. 5 is a partial plan view of the slit mounting member mounting jig 50. FIG. 3 and 4, for the sake of convenience of explanation, the route maintaining member 30 and the like to be mounted are shown. FIG. 6 is a schematic sectional view showing the slit mounting member mounting jig 50 during the mounting operation, FIG. 7 is a schematic perspective view showing the slit mounting member mounting jig 50 during the mounting operation, and FIG. FIG. 6 is a schematic sectional view taken along line VIII-VIII.

  The slit mounting member mounting jig 50 is a member formed of resin or the like, and is formed in a shape obtained by bending a plate-shaped member into a U shape. The plate-like member may be one that is initially formed in a flat plate shape and bent into a U shape, or may be one that has been molded into a U shape from the beginning. Here, a plate-shaped member is bent into a U shape by bending a member having a shape obtained by cutting out the apex of a substantially isosceles triangular flat plate shape along a vertical bisector of its base. A shape is formed. In the substantially isosceles triangular plate-like member, a plurality of hole portions 52 are formed at intervals along a perpendicular bisector of the base. And the said plate-shaped member is made to be able to be bent easily along the planned straight line.

  Outer edge portion 54 of the slit mounting member mounting jig 50 extending to both sides of the bent portion (the portion corresponding to the two oblique sides connected to the bottom of the substantially isosceles triangular shape) is an extension of the bent portion. It is formed in an inclined shape toward the one end side of the bent portion while skewing with respect to the direction. Further, by forming the outer piece portion of the outer edge portion 54 so as to project outward, a flange portion 55 that is inclined with respect to the extending direction of the bent portion is formed. Yes. The outer edge portion 54 and the flange portion 55 form a one-side tube guide portion 56 that guides one edge portion of the slit 24 in the corrugated tube 20. When the corrugated tube 20 moves along the one-side tube guide portion 56 in a state where the pair of one-side tube guide portions 56 is inserted into the slit 24 of the corrugated tube 20, the slit 24 is opened and the corrugated tube 20 is It is sent while being skewed toward one end of the bent portion. That is, the pair of one-side tube guide portions 56 is formed in a shape that can be inserted into the slit 24 of the corrugated tube 20 so as to be movable along the longitudinal direction of the corrugated tube 20, and the corrugated tube 20 is inserted into the slit 24. By being pulled out, an opening guide portion 57 for sending out the corrugated tube 20 while opening the slit 24 is configured.

  Further, a positioning portion 58 is provided at one end of the bent portion (left side in FIG. 3). The positioning portion 58 is provided on the delivery direction side of the corrugated tube 20 by the opening guide portion 57, and the end of the path maintaining member 30 can be disposed in the slit of the corrugated tube 20 delivered from the opening guide portion 57. It is comprised so that it may position in a correct position.

  That is, both side portions of the slit 24 in the corrugated tube 20 are guided through a passage surrounded by the outer edge portion 54 and the flange portion 55. Therefore, the positioning portion 58 is positioned so that the pair of concave groove portions 36g of the path maintaining member 30 positioned by the positioning portion 58 is positioned on the extension of the passage surrounded by the outer edge portion 54 and the flange portion 55. Is set.

  Here, the positioning portion 58 is a portion formed integrally with the end portion of the bent portion, and includes a pair of positioning end portions 59 that position the end portion of the path maintaining member 30 in the width direction. More specifically, a pair of positioning end portions 59 are formed on both sides of the concave portion 59h by forming a notch-shaped concave portion 59h in the central portion in the width direction of the end portion of the bent portion. The width W <b> 1 of the positioning end portion 59 is preferably set to be the same as the width of the connecting portion 31. And when the connection part 31 is pinched | interposed between the pair of positioning end parts 59, the position of the connection part 31 is regulated in the width direction. Note that the width W1 of the positioning end 59 is equal to the width of the connecting portion 31 as long as the connecting portion 31 is sandwiched between the pair of positioning end portions 59 using the elastic deformation of the positioning end portion 59 and its periphery. It may be smaller. In addition, the width W1 of the positioning end portion 59 is connected as long as the position of the connecting portion 31 can be regulated within a range in which the path maintaining member 30 can be disposed in the slit 24 of the corrugated tube 20 delivered from the opening guide portion 57. It may be larger than the width of the portion 31.

  In addition, a fixed portion 59a as a fixed convex portion protruding toward the inner side is provided on the inner portion of the distal end portion of the pair of positioning end portions 59. The fixing portion 59a is set to a size that can be fitted into the recess 38. It is preferable that the protrusion dimension of the fixing portion 59a is approximately the same as the depth dimension of the recess 38. The distance between the pair of fixed portions 59 a is preferably set smaller than the width of the connecting portion 31. And the connection part 31 can be arrange | positioned by elastically deforming the fixing | fixed part 59a, the positioning part 58, and its peripheral location, and expanding the space | interval between a pair of fixing | fixed part 59a. The pair of fixing portions 59a are fitted into the pair of recesses 38 by elastically returning the fixing portion 59a and the positioning portion 58 and their peripheral portions to the original shape. Thereby, the edge part of the path | route maintenance member 30 is fixed by the fixing | fixed part 59a (refer FIG. 4, FIG. 6-FIG. 8). Note that only one of the fixing portions 59a may be provided.

  The bent portion of the slit mounting member mounting jig 50 is formed in a semi-cylindrical harness guide 53 having a substantially U-shaped cross section. When the wire harness main body 12 guided through the inside from the other end portion of the harness guide portion 53 is guided to one end portion of the harness guide portion 53, the wire harness main body portion 12 is moved to the positioning portion 58. Further, it is guided on the side of the opening guide portion 57 so as to be disposed in the corrugated tube 20 through the slit 24 opened by the opening guide portion 57.

  A method for manufacturing the wire harness 10 using the slit mounting member mounting jig 50 will be described.

  First, the wire harness main body 12 is disposed in the harness guide 53. At this time, one end of the wire harness main body 12 is drawn outward from one end of the harness guide 53 (see FIG. 3). At this time, by opening both sides of the slit mounting member mounting jig 50, the mounting work of the wire harness body 12 can be easily performed.

  Next, the end of the path maintaining member 30 is positioned by the positioning unit 58. Here, the connecting portion 31 is disposed between the pair of positioning end portions 59 and the pair of fixing portions 59a are fitted into the pair of recessed portions 38, whereby the end portions of the path maintaining member 30 are positioned and fixed by the positioning portion 58. (See FIG. 4).

  Then, the opening guide portion 57 is inserted into the slit 24 on one end side of the corrugated tube 20.

  In addition, the order which performs said each process is arbitrary. For example, the wire harness main body 12 may be set after the end of the path maintaining member 30 is positioned and fixed to the positioning portion 58.

  Then, the one end portion of the corrugated tube 20 is pulled toward the positioning portion, and the corrugated tube 20 is sent out toward the positioning portion 58 while opening the slit 24 by the opening guide portion 57.

  When one end portion of the corrugated tube 20 opens and exceeds the guide portion 57, a portion of the wire harness main body portion 12 that extends from one end portion of the harness guide portion 53 is disposed in the corrugated tube 20 through the opened slit 24. Is done.

  When one end portion of the corrugated tube 20 exceeds the positioning portion 58, both side portions of the slit 24 in the corrugated tube 20 are disposed on both sides of the end portion of the path maintaining member 30 fixed by the positioning portion 58. Accordingly, the path maintaining member 30 is disposed in the opened slit 24, and both side portions of the slit 24 in the corrugated tube 20 are disposed in the pair of concave grooves 36 g of the path maintaining member 30.

  In this state, the portion of the wire harness main body portion 12 extending from the harness guide portion 53 is accommodated in the portion of the corrugated tube 20 beyond the opening guide portion 57, and the path is maintained in the slit 24 of the portion. The member 30 is disposed (see FIG. 7).

  In this state, the corrugated tube 20 and the wire harness main body portion 12 are pulled out from the opening guide portion 57 and the harness guide portion 53.

  Then, the path maintaining member 30 is sequentially disposed with respect to the slit 24 of the corrugated tube 20 drawn from the opening guide portion 57, and both side portions of the slit 24 of the corrugated tube 20 are a pair of concave grooves 36g. It is inserted into the inside sequentially. Further, with the effort of the corrugated tube 20 reaching the positioning portion 58, the portion of the wire harness main body portion 12 drawn out from the harness guide portion 53 is sequentially disposed in the corrugated tube 20 through the opened slit 24. Thereby, the wire harness main-body part 12 and the path | route maintenance member 30 are attached to the corrugated tube 20 one by one.

  When the entire corrugated tube 20 is pulled out, the entire path maintaining member 30 is attached to the corrugated tube 20, and the wire harness main body 12 is disposed in the entire corrugated tube 20. And if the positioning and fixation of the path | route maintenance member 30 by the positioning part 58 and the fixing | fixed part 59a are cancelled | released, the said wire harness 10 can be manufactured.

  As described above, according to the present embodiment, the slit 24 opened by the opening guide portion 57 can be guided toward the slit 24 positioned by the positioning portion 58. When the corrugated tube 20 is pulled out from the opening guide portion 57 in this state, the entire path maintaining member 30 is mounted in the slit 24. Therefore, the path maintaining member 30 can be easily attached to the slit 24 of the corrugated tube 20. Note that the positioning and fixing of the path maintaining member 30 by the positioning portion 58 and the fixing portion 59a may be released before the entire path maintaining member 30 is completely attached to the slit 24 of the corrugated tube 20.

  Moreover, since the slit mounting member mounting jig 50 is formed of a plate-like member bent into a U-shape, the configuration of the slit mounting member mounting jig 50 can be simplified.

  Moreover, since the positioning part 58 is integrally formed in the plate-shaped bending part, since the surface shape of those boundary parts exhibits a gentle property, the said boundary part is another member, especially the wire harness main-body part 12. Is hard to injure

  However, the configuration of the slit mounting member mounting jig 50 is not limited to the above example, and may be configured by a combination of a plurality of members. Further, it is only necessary that the opening guide portion 57 and the positioning portion 58 are integrally combined in the above positional relationship, and it is not essential that the opening guide portion 57 and the positioning portion 58 are formed by a plate-like member bent into a U shape as described above. .

  Further, since the U-shaped bent portion of the slit mounting member mounting jig 50 is a harness guide portion 53 that guides the wire harness body portion 12, the wire harness body portion 12 is guided by the harness guide portion 53. Thus, the wire harness main body 12 can be easily disposed in the corrugated tube 20 through the slit 24 before the positioning portion 58.

  Therefore, as described above, the operation of mounting the path maintaining member 30 on the corrugated tube 20 and the operation of mounting the wire harness main body 12 in the corrugated tube 20 can be easily performed.

  In addition, it is not essential to perform the mounting operation of the path maintaining member 30 and the mounting operation of the wire harness main body 12 at the same time. Even after the work of disposing the wire harness main body 12 in the corrugated tube 20, the work of attaching the path maintaining member 30 to the slit 24 of the corrugated tube 20 using the slit mounting member mounting jig 50 is performed. Good. In this case, the operation | work which arrange | positions the wire harness main-body part 12 in the corrugated tube 20 may use this slit mounting member mounting jig 50, and does not need to use it.

  Further, since the positioning portion 58 includes a pair of positioning end portions 59 for positioning the end portion of the path maintaining member 30 in the width direction, the path maintaining member 30 is positioned in the state where the path maintaining member 30 is positioned in the width direction. Can be disposed in the slit 24. Thereby, it can guide in the state where the end of path maintenance member 30 was correctly positioned to the width direction of slit 24, and mounting work of path maintenance member 30 can be performed easily.

  Further, the positioning end portion 59 includes a fixing portion 59 a that fixes the end portion of the path maintaining member 30. For this reason, it is possible to easily pull out the corrugated tube 20 in a state where the end of the path maintaining member 30 is fixed and the movement of the corrugated tube 20 in the pulling direction is suppressed. 30 can be easily attached.

  In addition, since the positioning end portion 59 includes the protruding fixing portion 59a that fits into the recess 38 of the path maintaining member 30, the path maintaining member 30 can be fixed more reliably.

  Note that it is not essential that the fixing portion fits into the recess 38 of the path maintaining member 30 as described above. For example, when a rubber slit mounting member is assumed as a member to be mounted in the slit 24, the protrusion-shaped fixing portion sandwiches both side portions of the rubber slit mounting member and bites in. The end of the slit mounting member can also be fixed. In such a case, the recess 38 may be omitted from the slit mounting member.

  Further, it is not essential that the positioning end portion 59 includes the fixing portion 59a.

  9 to 11 show modifications in which the fixing portion 59a is omitted. 9 is a schematic perspective view showing a slit mounting member mounting jig 150 according to a modification, FIG. 10 is a schematic plan view showing a positioning part 158 according to the modification, and FIG. 11 is a schematic showing the positioning part 158. It is sectional drawing.

  In this modification, it is assumed that the concave portion 38 is omitted as the route maintaining member 130.

  Further, the positioning portion 158 corresponding to the positioning portion 58 is formed in a shape extending from the end of the bent portion. Further, the positioning portion 158 includes a pair of positioning end portions 159 projecting with an interval. Between the pair of positioning end portions 159, a gap that is approximately the same as the width of the connecting portion 31 is provided. Further, the positioning end portion 159 is not provided with the fixing portion 59a.

  And the edge part of the connection part 31 of the path | route maintenance member 130 is faced by the positioning part 158, and is positioned between the pair of positioning edge parts 159, and is positioned in the width direction.

  In this modification, the positioning portion 158 extends outward from the bent portion. Therefore, when both side portions of the slit 24 of the corrugated tube 20 are disposed in the pair of concave groove portions 36g, the positioning portion 158 is positioned. It is preferable that the end portion 159 is formed to be sufficiently thin with respect to the groove width of the concave groove portion 36g so as not to press the space in the concave groove portion 36g (see FIG. 11). As a result, both side portions of the slit 24 in the corrugated tube 20 drawn out from the opening guide portion 57 are fitted into the recessed groove portion 36g even in the portion where the positioning end portion 159 is disposed in the recessed groove portion 36g. Can do.

  In FIG. 11, the portion indicated by the two-dot chain line in the concave groove portion 36g is the both side portions of the slit 24 in the corrugated tube 20, and in FIG. 11, the both side portions are disposed in the pair of concave groove portions 36g. The state in which the wire harness main body 12 guided through the harness guide part 53 is guided into the corrugated tube 20 through the slit 24 of the corrugated tube 20 is shown in front of the part.

  Also in this modified example, the same operation effect as the above-described embodiment can be obtained except for the operation effect by fixing the end portion of the path maintaining member 30.

  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.
