Hereinafter, the slit mounting member mounting jig, the manufacturing method of a wire harness, and the slit mounting member which concern on embodiment are demonstrated.

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 portion 12, a corrugated tube 20, and a path maintenance member 30 as a slit mounting member.

The wire harness main body 12 is configured to be bound by a plurality of electric wires. More specifically, the wire harness main body 12 is configured to be branched and bundled in accordance with the wiring form to the vehicle on which the plurality of electric wires are to be disposed. 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 disposition form. In order to prevent the wire harness main body 12 from interfering with the peripheral portion, the wire harness main body 12 may be maintained in a shape along the wiring form. In such a case, the path maintenance member 30 is mounted on the wire harness main body 12 together with the corrugated tube 20, and the wire harness main body 12 is maintained in a predetermined shape. The portion where the corrugated tube 20 and the path maintenance member 30 are attached to the wire harness main portion 12 may be at least a portion of the wire harness main portion 12 and is a portion of the wire harness main portion 12 Also, it may be 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 resin or the like. Since the corrugated tube 20 is easily elastically deformed at the step 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, a tube having an inner diameter larger than the outer diameter of the portion of the wire harness main body 12 to be mounted 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 so as to be split by the slit 24.

The path maintenance member 30 is an elongated member for maintaining the wire harness main body 12 and the corrugated tube 20 in a shape along a predetermined path.

Here, the path maintenance member 30 is formed in a fixed shape according to the disposition path in which the portion to be mounted in the wire harness main body 12 is disposed at the time of molding. In this case, the path maintenance member 30 is P.I. P. It is preferable to mold with a resin having a certain degree of rigidity such as (polypropylene). The path maintenance member 30 may be straight or curved in the entire longitudinal direction. When the path maintenance member 30 is curved, it may be curved in the entire longitudinal direction, or may be curved in only a part of the longitudinal direction.

The path maintenance member 30 is configured to be attachable to the corrugated tube 20 along the longitudinal direction. That is, the path maintenance member 30 includes a portion of the corrugated tube 20 in which the pair of recessed groove portions 36 g capable of receiving the end edge portions on both sides of the slit 24 are formed. In other words, the route maintaining member 30 is provided with the outer peripheral side protrusion 32 at one edge (outer periphery side) of the long connection portion 31 and the other edge (inner periphery) edge of the connection portion 31 The projection 33 is provided on the inner circumferential side, and the cross-sectional shape in a plane orthogonal to the longitudinal direction of the projection 33 is substantially H-shaped. The outer side surface of the outer peripheral side protrusion 32 has an arc-shaped curved surface that is convex outward. The width dimension of the recessed groove portion 36 g is set to a dimension substantially equal to or larger (slightly larger) than the thickness dimension of the corrugated tube 20.

The portion of the path maintenance member 30 where the pair of concave grooves 36g is formed may be the entire longitudinal direction of the path maintenance member 30, or may be a portion along the longitudinal direction. In the present embodiment, an example in which the pair of recessed groove portions 36 g are formed over the entire longitudinal direction of the path maintenance 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 portions 38 are formed on both side surfaces of the end portion of the connecting portion 31, and are formed in a concave shape of a rectangular parallelepiped surface shape opened outward. Of the recess 38, the surface 38a on the connection portion 31 side, that is, the surface 38a facing the longitudinal direction intermediate portion side of the path maintenance member 30, moves the fixing portion 59a described later to the end side of the path maintenance member 30. It is set as the fixed surface 38a to suppress (refer FIG. 6). Then, in a state in which each of a pair of fixing portions 59a described later is fitted into the pair of concave portions 38, by abutting on the fixing surface 38a, the main path maintenance member 30 is not moved to the longitudinal middle portion side The end of the path maintenance member 30 is fixed by the pair of fixing portions 59a.

Then, the route maintenance member 30 is disposed in the slit 24 of the corrugated tube 20 in a state in which the wire harness main body 12 is disposed in the corrugated tube 20. In this state, both side edge portions sandwiching the slit 24 in the corrugated tube 20 are fitted into the pair of recessed groove portions 36g. Thus, the wire harness main body 12 and the corrugated tube 20 are integrated with the path maintenance member 30 in a state of being bent along the shape of the path maintenance member 30.

Thereafter, as required, tie bands, adhesive tapes, etc. are wound around the outer periphery of the corrugated tube 20, and 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 maintenance member may be a member that is plastically deformable and exhibits rigidity to maintain 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 maintenance member 30 may be molded with an elastomer such as rubber, and a shape maintenance line may be embedded in the inside along the longitudinal direction. As a path | route maintenance member, metal wires, such as an iron wire, a copper wire, a stainless steel wire, or these alloy wires, or resin etc. which show a certain amount of rigidity after plastic deformation can be used.

Moreover, although it demonstrates by the path | route maintenance member 30 which maintains the path | route of the wire harness main-body part 12 as a slit mounting member here, a slit mounting member does not necessarily need to perform the path | route maintenance of the wire harness main-body part 12. For example, the slit mounting member is formed of an elastic material such as elastomer (rubber or the like), and the path maintenance of the wire harness main body 12 is not performed, but it is mounted to the slit 24 similarly to the above to close the slit 24 It may be configured as a member.

The operation of arranging the path maintenance member 30 over the long slit 24 of the corrugated tube 20 is a very difficult operation. In particular, when the path maintenance member 30 is used for the purpose of maintaining the wire harness 10 in a bent shape, the path maintenance member 30 itself is formed in a bent shape in various manners. Also from this point, the operation of inserting the path maintenance member 30 into the slit 24 becomes difficult.

The slit attachment member attachment jig of the present embodiment is a jig for easily attaching the path maintenance 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. In FIG. 3 and FIG. 4, the route maintenance member 30 etc. to be mounted are shown for convenience of explanation. 6 is a schematic cross-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. 6 is a schematic sectional view taken along line VIII-VIII of FIG.

The slit mounting member mounting jig 50 is a member formed of resin or the like, and is formed in a shape in which a plate-like member is bent in a U-shape. The plate-like member may be a plate-shaped member that is initially formed into a flat plate and bent into a U-shape, or may be formed into a U-shaped bend from the beginning. Here, the plate-like member is bent in a U-shape by bending a substantially isosceles triangular flat plate-shaped member into a substantially U shape along a vertical bisector of the bottom side. The shape is formed. Among the substantially isosceles triangle plate-shaped members, a plurality of holes 52 are formed at intervals along the vertical bisector of the bottom side. Then, the plate-like member can be easily bent along a planned straight line.

The outer edge 54 (a portion corresponding to two oblique sides connected to the base in the substantially isosceles triangle shape) of the portion extending on both sides of the bent portion of the slit mounting member mounting jig 50 is an extension of the bent portion It is formed in the inclination shape which goes to the one end side of the said bending part, being skewed with respect to direction. Further, by forming a shape in which the outer piece portion of the outer edge portion 54 is bent so as to extend outward, a flange portion 55 which is oblique to the extending direction of the bent portion is formed. There is. The outer edge portion 54 and the flange portion 55 form a one-side tube guiding portion 56 for guiding the edge portion on one side of the slit 24 in the corrugated tube 20. When the corrugated tube 20 moves along the one-sided tube guiding portion 56 in a state where the pair of one-sided tube guiding portions 56 is inserted into the slit 24 of the corrugated tube 20, the corrugated tube 20 is opened while the slit 24 is opened. It is delivered while being skewed toward one end of the bent portion. That is, the pair of one-side tube guiding portions 56 is formed in the slit 24 of the corrugated tube 20 so as to be movably inserted along the longitudinal direction, and the corrugated tube 20 is inserted in the slit 24. By being pulled out, an open guide portion 57 for delivering the corrugated tube 20 while opening the slit 24 is configured.

Moreover, the positioning part 58 is provided in the one end part (left side of FIG. 3) of the said bending part. 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 maintenance member 30 can be disposed in the slit of the corrugated tube 20 delivered from the opening guide portion 57. It is configured to be positioned at any position.

That is, both sides of the slit 24 in the corrugated tube 20 are guided through a passage surrounded by the outer edge 54 and the flange 55. Therefore, the positioning portion 58 is positioned such that the pair of recessed groove portions 36g of the path maintenance 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. It is set.

Here, the positioning portion 58 is a portion integrally formed at the end of the bent portion, and includes a pair of positioning ends 59 for positioning the end of the path maintenance member 30 in the width direction. More specifically, a pair of positioning end portions 59 is formed on both sides of the recess 59 h by forming a notch-like recess 59 h at the center in the width direction of the end of the bent portion. Preferably, the width W1 of the positioning end 59 is set to be the same as the width of the connecting portion 31. Then, the connecting portion 31 is interposed between the pair of positioning end portions 59, whereby the connecting portion 31 is positionally restricted in the width direction. The width W 1 of the positioning end portion 59 is equal to the width of the connecting portion 31 as long as the connecting portion 31 can be sandwiched between the pair of positioning end portions 59 using elastic deformation of the positioning end portion 59 and the periphery thereof. It may be smaller. Further, the width W1 of the positioning end portion 59 is the connection if the position of the connecting portion 31 can be regulated within the range where 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 part 31.

Further, on the inner side of the tip end portion of the pair of positioning end portions 59, a fixing portion 59a as a fixing convex portion protruding toward the inside is provided. The fixing portion 59 a is set to a size that can be fitted into the recess 38. It is preferable that the projecting dimension of the fixing portion 59 a be approximately the same as the depth dimension of the recess 38. The spacing dimension of the pair of fixing portions 59 a is preferably set smaller than the width of the connecting portion 31. Then, the connecting portion 31 can be disposed by elastically deforming the fixing portion 59a, the positioning portion 58, and the peripheral portion thereof to widen the space between the pair of fixing portions 59a. Then, the fixing portion 59a, the positioning portion 58, and the peripheral portion thereof are elastically returned to the original shape, whereby the pair of fixing portions 59a is fitted into the pair of concave portions 38. Thus, the end of the path maintenance member 30 is fixed by the fixing portion 59a (see FIGS. 4 and 6 to 8). Note that only one fixing portion 59a may be provided.

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

A method of 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 the 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 operation of the wire harness main body 12 can be easily performed.

Next, the end of the path maintenance 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 end portion of the path maintenance member 30 is positioned and fixed by the positioning portion 58 by fitting the pair of fixing portions 59a into the pair of concave portions 38. (See FIG. 4).

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

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

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

When one end of the corrugated tube 20 opens and passes over the guide portion 57, a portion of the wire harness main portion 12 extending from the one end of the harness guiding portion 53 is disposed in the corrugated tube 20 through the opened slit 24. Be done.

When one end of the corrugated tube 20 passes the positioning portion 58, both sides of the slit 24 of the corrugated tube 20 are disposed on both sides of the end of the path maintaining member 30 fixed by the positioning portion 58. Thus, the path maintaining member 30 is disposed in the opened slit 24, and both sides of the slit 24 in the corrugated tube 20 are disposed in the pair of recessed groove portions 36 g of the path maintaining member 30.

In this state, the portion of the wire harness main portion 12 extending from the harness guiding portion 53 is accommodated in the portion of the corrugated tube 20 beyond the opening guide portion 57, and the path maintenance is performed 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 portion 12 are pulled out from the opening guide portion 57 and the harness guiding portion 53.

Then, the path maintenance member 30 is sequentially disposed with respect to the slit 24 of the portion drawn out from the open guide portion 57 of the corrugated tube 20, and both side portions of the slit 24 of the corrugated tube 20 are a pair of recessed groove portions 36g. It will be inserted sequentially in the inside. Further, when the corrugated tube 20 reaches the positioning portion 58, the portion of the wire harness main portion 12 drawn out from the harness guiding portion 53 is sequentially disposed in the corrugated tube 20 through the opened slit 24. Thus, the wire harness main body 12 and the path maintenance member 30 are sequentially mounted on the corrugated tube 20.

When the entire corrugate tube 20 is pulled out, the entire path maintenance member 30 is attached to the corrugate tube 20, and the wire harness body 12 is disposed inside the entire corrugate tube 20. Then, when the positioning and fixing of the path maintenance member 30 by the positioning portion 58 and the fixing portion 59a are released, the wire harness 10 can be manufactured.

As described above, according to the present embodiment, the slit 24 opened by the open guide portion 57 can be guided toward the slit 24 positioned by the positioning portion 58. In this state, when the corrugated tube 20 is pulled out from the open guide portion 57, the entire path maintenance member 30 is mounted in the slit 24. Therefore, the path maintenance member 30 can be easily attached to the slit 24 of the corrugated tube 20. 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 whole of the path maintaining member 30 is completely attached to the slit 24 of the corrugated tube 20.

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

Further, since the positioning portion 58 is integrally formed on the plate-like bent portion, the surface shape of the boundary portion thereof exhibits a gentle property, so that the boundary portion is another member, in particular, the wire harness main portion 12 Hard to get hurt.

Of course, the configuration of the slit attachment member attachment jig 50 is not limited to the above example, and may be a combination of a plurality of members. Further, it is not essential that the open guide portion 57 and the positioning portion 58 be integrally combined in the above-described positional relationship, and that they be formed by the plate-like member bent in a U-shape as described above. .

Further, since the U-shaped bent portion of the slit mounting member mounting jig 50 is used as the harness guiding portion 53 for guiding the wire harness main portion 12, the wire guiding portion 53 is guided by the harness guiding 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 attaching the path maintenance member 30 to the corrugated tube 20 and the operation of attaching 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 work of the path | route maintenance member 30 and the mounting work of the wire harness main-body part 12 simultaneously. Even if the wire harness main body 12 is disposed in the corrugated tube 20, then the route maintaining member 30 is attached to the slit 24 of the corrugated tube 20 using the slit attachment member attaching jig 50. Good. In this case, the work for mounting the wire harness main body 12 in the corrugated tube 20 may or may not use the slit mounting member mounting jig 50.

In addition, since the positioning portion 58 includes the 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 width direction. Can be disposed in the slit 24. As a result, the end of the path maintenance member 30 can be guided accurately with respect to the width direction of the slit 24, and the mounting operation of the path maintenance member 30 can be easily performed.

The positioning end 59 also includes a fixing portion 59 a that fixes the end of the path maintenance member 30. Therefore, the corrugated tube 20 can be easily pulled out while fixing the end of the route maintaining member 30 and suppressing the movement of the corrugated tube 20 in the pulling direction, from this point as well, the route maintaining member 30 installation work can be done easily.

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

It is not essential that the fixing portion be fitted into the recess 38 of the path maintenance member 30 as described above. For example, in the case where a rubber slit mounting member is assumed as a member mounted in the slit 24, the projection-like fixing portion may also be inserted by sandwiching and biting in both sides of the rubber slit mounting member. The end of the slit mounting member can also be fixed. In such a case, the recess 38 may be omitted in the slit mounting member.

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

9 to 11 show a modification in which the fixing portion 59a is omitted. FIG. 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 portion 158 according to the modification, and FIG. FIG.

In this modification, as the path maintenance member 130, it is assumed that the recess 38 is omitted.

Moreover, the positioning part 158 corresponding to the positioning part 58 is formed in the shape extended from the edge part of a bending part. Also, the positioning portion 158 includes a pair of positioning end portions 159 protruding with a space. A gap about the same as the width of the connecting portion 31 is provided between the pair of positioning end portions 159. Further, the fixing portion 59 a is not provided at the positioning end portion 159.

Then, the end of the connection portion 31 of the path maintenance member 130 is abutted against the positioning portion 158 and is positioned between the pair of positioning end portions 159 so as to be positioned in the width direction.

In the present modification, since the positioning portion 158 extends outward from the bent portion, when the both sides of the slit 24 in the corrugated tube 20 are disposed in the pair of recessed groove portions 36g, positioning is performed. It is preferable that the groove width of the recessed groove 36g be sufficiently thin so that the end portion 159 does not press the space in the recessed groove 36g (see FIG. 11). Thereby, both sides of the slit 24 of the corrugated tube 20 drawn out from the open guide portion 57 are fitted into the recessed groove 36g even in the portion where the positioning end 159 is disposed in the recessed groove 36g. Can.

In FIG. 11, a portion indicated by a two-dot chain line in the recessed groove portion 36g is 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 recessed groove portions 36g. The wire harness main body portion 12 guided through the harness guide portion 53 is guided through the slit 24 of the corrugated tube 20 and into the corrugated tube 20 in front of the portion.

Also in this modification, the same effects as those of the above embodiment can be obtained except for the effects by fixing the end of the path maintenance member 30.

As mentioned above, although this invention was explained in detail, the above-mentioned explanation is illustration in all the aspects, and this invention is not limited to it. It is understood that countless variations not illustrated are conceivable without departing from the scope of the present invention.
