  However, although the corrugated tube itself has good bendability and can be bent according to the bending form of the wire harness, it is difficult to keep the form constant. Therefore, in order to maintain the wire harness in the routing configuration, it is necessary to attach a clamp member to the wire harness or the corrugated tube and fix the clamp member at a predetermined position of the vehicle. If the number of fixing points by the clamp member increases, there is a risk of increasing the number of work steps and the cost of parts.

  Therefore, by the applicant of the present invention, a path maintaining member molded in a long shape bent in at least a part of the extending direction is attached to the corrugated tube, and the wire harness inside the corrugated tube is maintained in the routing form.

  Hereinafter, the corrugated tube 10 with a path maintenance member and the path maintenance wire harness 50 according to the embodiment will be described (see FIG. 1). The corrugated tube 10 with a path maintaining member is a member for maintaining the wiring path while protecting the wire harness 1.

  For convenience of explanation, the wire harness 1 to which the corrugated tube with path maintaining member 10 is applied will be described. The wire harness 1 is a wire harness routed in a vehicle or the like, and has at least one electric wire. Here, the wire harness 1 is formed by binding a plurality of electric wires. And the wire harness 1 is routed along a routing route.

  The corrugated tube 10 with a path maintaining member is applied to a portion of the wire harness 1 that is a path maintenance target. For example, the part that is subject to route maintenance is a part that is routed on a routing path that includes a curved path, a part that is routed on a routing path in which other members are disposed in the vicinity, and the like. is there. This routing route is a route including a straight line shape, a curved line shape, or both. And the corrugated tube 10 with a path | route maintenance member protects the wire harness 1 over the extension direction, and maintains the wire harness 1 in a wiring path | route in part or the whole of the extension direction. More specifically, the corrugated tube 10 with a path maintenance member is configured to maintain a portion of the wire harness 1 that is a path maintenance target in the routing path.

  The corrugated tube 10 with a path maintaining member includes a corrugated tube 20 and a path maintaining member 30 (see FIG. 2).

  The corrugated tube 20 is a member formed in a cylindrical shape in which annular convex portions 22 and annular concave portions 24 are alternately provided in the axial direction. That is, the corrugated tube 20 has a wave shape (substantially rectangular wave shape) in a cross-sectional view orthogonal to the circumferential direction (see FIG. 4). The corrugated tube 20 has a shape in which a top portion of the annular convex portion 22 and a bottom portion of the annular concave portion 24 are connected by a side wall portion 26 substantially orthogonal to the axial direction. The side wall portion 26 is a side wall portion of each of the annular convex portion 22 and the annular concave portion 24 and is a portion shared by both. Hereinafter, focusing on the annular convex portion 22 or the annular concave portion 24, it may be referred to as the side wall portion 26 of the annular convex portion 22 or the side wall portion 26 of the annular concave portion 24. The corrugated tube 20 is bent in such a manner that the annular convex portions 22 or the annular concave portions 24 arranged in the axial direction are close to or separated from each other.

  Further, the corrugated tube 20 has a slit 28 formed along a part of the circumferential direction along the axial direction. That is, the wire harness 1 can be disposed inside the corrugated tube 20 through the slit 28.

  The path maintaining member 30 is a member that is attached to the corrugated tube 20 and maintains the corrugated tube 20 in a form along the wiring path of the wire harness 1. The path maintaining member 30 also serves to suppress the opening of the slit 28 of the corrugated tube 20. The path maintaining member 30 is formed in a long shape having a locking portion, an interposition portion 36 connected to the locking portion, and a positioning protrusion 42. The locking part has an outer peripheral locking part 32 and an inner peripheral locking part 34.

  Schematically, the path maintaining member 30 has a shape in which an outer peripheral side locking part 32 and an inner peripheral side locking part 34 are connected by an interposition part 36. In the state where the interposition part 36 is interposed in the slit 28 of the corrugated tube 20, the path maintaining member 30 has the outer peripheral side locking part 32 locked from the outer peripheral side to the edge portions on both sides of the slit 28. The inner peripheral side locking portion 34 is attached to the corrugated tube 20 in such a manner that the inner peripheral side locking portion 34 is locked from the inner peripheral side to the edge portions on both sides of the slit 28.

  More specifically, the interposition part 36 is a part formed in a long shape along the extending direction of the path maintaining member 30. This interposition part 36 is sandwiched between edge portions on both sides of the slit 28 (the direction perpendicular to the extending direction of the path maintaining member 30 and the direction connecting the inner peripheral side locking part 34 and the outer peripheral side locking part 32). ) In a thin flat shape. Further, the dimension of the interposition part 36 in the direction connecting the inner peripheral side locking part 34 and the outer peripheral side locking part 32 is set to be larger than the dimensions of the annular convex part 22 and the annular concave part 24 in the inner and outer directions of the corrugated tube 20. (See FIG. 3). That is, the interposition part 36 supports the outer peripheral side locking part 32 and the inner peripheral side locking part 34 at a position sandwiching the edge portions on both sides of the slit 28 while being interposed in the slit 28.

  The interposition part 36 is maintained in a state of being sandwiched between edge portions on both sides of the slit 28 in a state where the path maintaining member 30 is attached to the corrugated tube 20.

  The outer peripheral side locking portion 32 is a portion that is elongated along the extending direction of the path maintaining member 30. The outer peripheral side locking portion 32 is set to a size larger than the interposition portion 36 in the extending direction of the path maintaining member 30 and the direction orthogonal to the direction connecting the inner peripheral side locking portion 34 and the outer peripheral side locking portion 32. (See FIG. 3). In addition, the outer peripheral side locking portion 32 has a curved surface portion 33 that is convex toward the outer peripheral side of the corrugated tube 20 (opposite side of the interposition portion 36).

  And the outer peripheral side latching | locking part 32 is arrange | positioned in the position of the outer peripheral side of the slit 28 in the state in which the path | route maintenance member 30 was attached to the corrugated tube 20, and extends along the axial direction.

  The inner peripheral side locking portion 34 is a portion that is formed in an elongated shape along the extending direction of the path maintaining member 30. The inner peripheral side locking portion 34 is larger than the interposition portion 36 in the direction perpendicular to the extending direction of the path maintaining member 30 and the direction connecting the inner peripheral side locking portion 34 and the outer peripheral side locking portion 32. It is set (see FIG. 3). Here, the dimension of the inner peripheral side locking portion 34 in the above direction is set to be smaller than the dimension of the outer peripheral side locking portion 32 in the direction.

  And the inner peripheral side latching | locking part 34 is arrange | positioned in the inside of this corrugated tube 20 in the position of the inner peripheral side of the slit 28 in the state in which the path | route maintenance member 30 was attached to the corrugated tube 20, and the axial direction Extending along.

  The positioning protrusion 42 is a part for positioning the path maintaining member 30 in the axial direction with respect to the corrugated tube 20. The positioning protrusion 42 protrudes into the space inside the outer peripheral side locking part 32 and the inner peripheral side locking part 34 (locking part) and the interposition part 36, and in the axial direction of the corrugated tube 20, With respect to the side wall part 26 of the cyclic | annular convex part 22, it forms so that it can latch from the inner side of this cyclic | annular recessed part 24, or the inner side of the cyclic | annular convex part 22. FIG. Here, the inner side of the annular concave portion 24 or the inner side of the annular convex portion 22 does not indicate the inner peripheral side but indicates a space between the respective side wall portions 26.

  Here, the positioning protrusion 42 is formed so as to be able to be engaged with the side wall 26 of the annular recess 24 from the inside of the annular recess 24 in the axial direction of the corrugated tube 20. The positioning protrusion 42 protrudes from the outer peripheral locking portion 32 to the inner peripheral side (see FIGS. 3 and 4). Further, the positioning protrusion 42 is formed in a substantially rectangular shape when viewed from the extending direction of the path maintaining member 30. Further, one side of the positioning protrusion 42 is connected to the interposition part 36.

  The protruding dimension of the positioning protrusion 42 is set to be the same as or smaller than the dimension in the inner and outer directions of the annular protrusion 22 (slightly smaller here). In other words, the positioning protrusion 42 is present between the inner peripheral side locking portion 34 with an interval at which the bottom of the annular recess 24 of the corrugated tube 20 can be disposed. Further, the dimension of the positioning protrusion 42 in the extending direction of the path maintaining member 30 is equal to or smaller than the annular recess 24 (the interval between adjacent annular protrusions 22) in the axial direction of the corrugated tube 20 (here, Set slightly smaller). In other words, the dimension of the positioning protrusion 42 in the extending direction of the path maintaining member 30 is not limited as long as it can be fitted into the annular recess 24 and can be locked to the side wall 26 of the annular recess 24. .

  Here, being able to be locked to the side wall portion 26 means that an external force that moves in the axial direction of the corrugated tube 20 acts on the path maintaining member 30 in a state where the positioning protrusion 42 is fitted in the annular recess 24. In addition, the positioning protrusion 42 contacts the side wall 26 of the annular recess 24 and does not move over the side wall 26. For example, the shape that can be locked to the side wall portion 26 is a shape having a surface inclined at an angle larger than 45 degrees with respect to the extending direction, and is larger than half of the dimension in the inner and outer directions of the annular recess 24, preferably reaching the bottom. A shape or the like set to the protruding amount can be employed.

  Here, the positioning protrusion 42 has a locking surface 44 orthogonal to the extending direction of the path maintaining member 30. More specifically, the locking surface 44 is a rectangular surface. In addition, here, the positioning protrusion 42 has a pair of locking surfaces 44 that are orthogonal to the extending direction on both sides of the path maintaining member 30 in the extending direction. That is, the positioning protrusion 42 determines the position in the extending direction of the path maintaining member 30 by the pair of locking surfaces 44 locking to the both side walls 26 of the annular recess 24.

  Here, the positioning protrusion 42 is provided at one end in the extending direction of the path maintaining member 30. The one end portion is not required until the positioning protrusion 42 is flush with the one end surface of the outer peripheral side locking portion 32 in the extending direction of the path maintaining member 30. That is, the positioning protrusion 42 may be provided at a position slightly on the other end side from the one end surface of the outer peripheral side locking portion 32 in the extending direction of the path maintaining member 30. More specifically, the positioning protrusion 42 has a pair of adjacent distances from the one end surface of the outer peripheral side locking portion 32 in the extending direction of the path maintaining member 30 in the axial direction of the corrugated tube 20. It is provided at a position in a range smaller than the dimension between the end portions of the annular convex portion 22 and the annular concave portion 24. Here, the positioning protrusion 42 is provided at a position on the other end side in the axial direction dimension of the annular convex portion 22 from the one end surface of the outer peripheral side locking portion 32 among the one end portions in the extending direction of the path maintaining member 30. It has been.

  However, from the viewpoint of workability of attaching the path maintaining member 30 to the corrugated tube 20, the positioning protrusion 42 is flush with one end face of the outer peripheral side locking part 32 in the extending direction of the path maintaining member 30. It is preferable that it is provided at the position. FIG. 5 shows a path maintaining member 130 according to a modified example having a positioning protrusion 142 provided at a position flush with one end surface of the outer peripheral side locking portion 32 in the extending direction of the path maintaining member 30. ing. According to this configuration, it is possible to more reliably suppress the positioning protrusion 142 from being caught by the annular protrusion 22 during the attachment work of the path maintaining member 30 to the corrugated tube 20.

  Further, the positioning protrusions 42 are provided on both sides of the interposition part 36. That is, the positioning protrusion 42 is fitted into the annular recess 24 at the edge portions on both sides of the slit 28.

  The corrugated tube 10 with a path maintaining member maintains the wire harness 1 in the routing path in a state where the wire harness 1 is inserted inside. And the path | route maintenance wire harness 50 is comprised by attaching the corrugated tube 10 with a path | route maintenance member to the path | route maintenance object part of the wire harness 1. FIG.

  More specifically, first, the wire harness 1 is disposed on the inner side through the slit 28 with respect to the corrugated tube 20 to which the path maintaining member 30 is not attached.

  Next, the path maintaining member 30 is attached to the corrugated tube 20. That is, the path maintaining member 30 is arranged in such a manner that the inner peripheral side locking portion 34 is disposed inside the corrugated tube 20 and the interposition portion 36 is interposed in the slit 28 along the axial direction of the corrugated tube 20. Insert into. At this time, the path maintaining member 30 may be inserted into the slit 28 from the end opposite to the position where the positioning protrusion 42 is provided in the extending direction (see FIG. 2). Thereby, it can suppress that the positioning protrusion 42 is caught in the cyclic | annular convex part 22 of the corrugated tube 20 in the middle of attachment work. This attachment work may be performed using a jig for attachment work that opens the slit 28.

  When the path maintaining member 30 is inserted into the slit 28 to the other end in the extending direction, the positioning protrusion 42 provided at the other end in the extending direction is fitted into the annular recess 24 of the corrugated tube 20. Thereby, the positioning protrusion 42 can be locked to both side wall portions 26 of the annular recess 24 from the inside of the annular recess 24. That is, the path maintaining member 30 is movable in the axial direction of the corrugated tube 20 in a state where the positioning protrusion 42 is not fitted in the annular recess 24. In this state, the position of the path maintaining member 30 relative to the corrugated tube 20 may be adjusted. More specifically, the positioning protrusion 42 is fitted into the annular recess 24 at a position where the path maintaining member 30 is attached to the attachment target portion in the axial direction of the corrugated tube 20. Accordingly, the path maintaining member 30 is positioned in the axial direction of the corrugated tube 20.

  In this state, the position of the corrugated tube 10 with a path maintaining member is adjusted so that the path maintaining member 30 is disposed at the outer peripheral position of the path maintaining target portion in the extending direction of the wire harness 1. And the corrugated tube 10 with a path | route maintenance member is fixed by tape winding etc. with respect to the wire harness 1 extended to the extension direction side. Moreover, it is good to wind a tape around the outer peripheral part of the corrugated tube 10 with a path | route maintenance member. At this time, since the curved surface portion 33 is provided on the outer peripheral portion of the outer peripheral side locking portion 32 of the path maintaining member 30, the tape is wound around the curved surface along the curved surface portion 33 and the outer peripheral portion of the corrugated tube 20.

  In the path maintenance wire harness 50 configured as described above, the wire harness 1 is protected from the outside by the corrugated tube 20. Moreover, the part to which the path | route maintenance member 30 was attached among the corrugated tubes 20 is maintained in the shape along the wiring path | route of the wire harness 1, and the wire harness 1 inside that is maintained by the wiring path | route.

  According to the corrugated tube 10 with a path maintaining member and the path maintaining wire harness 50 according to the above embodiment, the path maintaining member 30 has an outer peripheral side locking portion 32 that is peripheral to the edge portions on both sides of the slit 28 of the corrugated tube 20. The inner peripheral side locking portion 34 is locked from the inner peripheral side with respect to the edge portions on both sides of the slit 28 of the corrugated tube 20, and the outer peripheral side locking portion 32 and the inner peripheral side locking portion are locked. 34 is interposed in the slit 28, and a positioning protrusion 42 that protrudes from the outer peripheral side locking portion 32 to the inner peripheral side is formed on the side wall portion 26 of the annular recess 24 in the axial direction of the corrugated tube 20. On the other hand, it is attached to the corrugated tube 20 in a form that can be locked from the inside of the annular recess 24. For this reason, when the path | route maintenance member 30 is attached with respect to the corrugated tube 20, positioning of the path | route maintenance member 30 with respect to the corrugated tube 20 can be performed without a positioning jig. Moreover, the path maintenance member 30 can be attached while visually observing the positioning protrusion 42 from the outer peripheral side of the corrugated tube 20, which contributes to improvement in workability.

  Further, since the positioning protrusion 42 is provided at one end in the extending direction of the path maintaining member 30, when the path maintaining member 30 is attached to the corrugated tube 20, By attaching the end part last, it is possible to suppress the positioning protrusion 42 from being caught on the annular convex part 22 during the attaching work, which contributes to improvement of working efficiency.

  In addition, since the positioning protrusion 42 has a locking surface 44 orthogonal to the extending direction of the path maintaining member 30, it can be more securely locked to the side portion of the annular convex portion 22, The path maintaining member 30 can be more reliably positioned with respect to the corrugated tube 20.

  So far, the corrugated tube 20 has been described as an example of a cylindrical shape, but may be formed in another cylindrical shape such as an elliptical cylindrical shape.

  Further, until now, the example in which the engaging part of the path maintaining member 30 has the outer peripheral side engaging part 32 and the inner peripheral side engaging part 34 has been described. It is only necessary to have a structure that locks from at least one of the outer peripheral side and the inner peripheral side with respect to the edge portions on both sides. There may be.

  Moreover, although the positioning protrusion 42 was formed in the shape which protrudes in the inner peripheral side from the outer peripheral side latching | locking part 32, it has demonstrated as what can be latched to the cyclic | annular convex part 22 in the axial direction of the corrugated tube 20. The configuration is not limited to this. Like the path maintaining member 230 according to the modification shown in FIGS. 6 and 7, the positioning protrusion 242 may be formed in a shape that protrudes from the inner peripheral side locking portion 34 toward the outer peripheral side. That is, the positioning protrusion 242 is fitted into the inner space of the annular protrusion 22 from the inner peripheral side of the corrugated tube 20 and can be locked to the side wall 26 of the annular protrusion 22 in the axial direction.

  Further, the positioning protrusion is not limited to being provided at one end of the path maintaining member 30 in the extending direction, and may be provided at the other end in the extending direction or in the middle. Furthermore, although the example in which only one positioning protrusion 42 has been provided in the extending direction of the path maintaining member 30 has been described so far, a plurality of positioning protrusions may be provided in the extending direction. The positioning protrusion that can be locked to the side wall 26 from the inside of the annular recess 24 of the corrugated tube 20 and the positioning protrusion that can be locked to the side wall 26 from the inside of the annular protrusion 22 are one path. It may be provided on the maintenance member.

  Moreover, although the positioning protrusion was demonstrated in the example provided in the both sides of the interposition part 36, it may be provided only in either one of the interposition part 36. FIG.

  As mentioned above, although corrugated tube 10 with a path maintenance member and path maintenance wire harness 50 were explained in detail, the above-mentioned explanation is illustration in all the aspects, and this invention is not limited to it. . The various modifications described above can be applied in combination as long as they do not contradict each other. And it is understood that the countless modification which is not illustrated can be assumed without deviating from the scope of the present invention.
