But the part to which the harness clamp 10 of the wire harness 1 is attached may be comprised by bundling an electric wire bundle with a tape, and the electric wire bundle may be covered with the exterior member. And the wire harness 1 may have a different diameter depending on a part in the extending direction, a vehicle type, or a vehicle having a different version even at the same wiring location. Hereinafter, for convenience of explanation, a wire harness 1 having a diameter larger than a reference dimension (for example, 5 mm) may be referred to as a large-diameter wire harness 1a, and a diameter less than the reference dimension may be referred to as a small-diameter wire harness 1b. .

  The wire harness 1 is routed to the vehicle along the routing route. At this time, the wire harness 1 is partially fixed to each part of the vehicle (fixed counterpart part 90) in the extending direction. The fixing counterpart 90 is, for example, a metal panel that constitutes the vehicle body of the vehicle, and is formed with a fixing hole 92 that penetrates in the thickness direction.

More specifically, the band portion 30 is formed in a shape in which a plurality of concave locked portions 32 opened on one main surface are arranged at intervals in the longitudinal direction (see FIG. 4).

  The band part 30 is provided so as to extend from the fixing part 20, and is wound around the outer peripheral part of the wire harness 1 on the support surface 28 side of the fixing part 20 (see FIG. 4). Here, the band portion 30 is inserted into the pair of band insertion hole portions 45. More specifically, the band portion 30 has both ends extending from the insertion direction S front side of the insertion portion 22 with respect to the pair of band insertion hole portions 45, and the intermediate portion extends from the insertion direction rear side. Are inserted in a ring shape. That is, the band portion 30 is wound around the outer peripheral portion of the wire harness 1 disposed along the first direction R at a position facing the support surface 28, and both end portions are each a pair of band insertion hole portions 45. Is inserted. This form is a winding form of the band part 30.

  The band locking part 40 is a part that locks the band part 30 and maintains the band part 30 in a winding form. Here, the band locking portion 40 is provided in each of the pair of band insertion hole portions 45 in the fixing portion 20 (see FIGS. 3 and 4). The pair of band locking portions 40 are formed so as to restrict the band portion 30 inserted through the pair of band insertion hole portions 45 from moving forward in the insertion direction S of the insertion portion 22.

  Each of the pair of band locking portions 40 is formed in a shape protruding into the pair of band insertion hole portions 45. More specifically, the band locking portion 40 has a protrusion having a locking surface that faces the front side in the insertion direction S of the insertion portion 22 and is substantially orthogonal to the insertion direction S. The band locking portion 40 has a locking surface that is engaged with an inner surface facing the rear side in the insertion direction S of the locked portion 32 of the band portion 30 inserted into the pair of band insertion hole portions 45. By stopping, the movement of the band part 30 is regulated.

  Here, the band locking portion 40 has two protrusions arranged in the penetrating direction of the band insertion hole 45. That is, the band locking portion 40 is simultaneously locked to the two locked portions 32.

  The small protrusion 50 and the large protrusion 60 are portions for suppressing the harness clamp 10 from rotating (laterally shifting) in the direction of rotation or extension around the central axis with respect to the wire harness 1 to be fixed.

  The small protrusion 50 is a part that mainly suppresses the rotation and movement of the harness clamp 10 relative to the small-diameter wire harness 1b. The small protrusion 50 protrudes from at least one of the positions on both sides of the band portion 30 (the pair of band insertion hole portions 45) in the first direction R on the support surface 28 of the fixed portion 20. Here, the small protrusions 50 are provided at positions on both sides of the band portion 30 in the direction along the first direction R. The small protrusions 50 are provided at positions on both sides of the center in the second direction R. That is, four small protrusions 50 are provided here.

  Moreover, the small protrusion 50 is set to the protrusion dimension which can bite into the outer peripheral surface of the small diameter wire harness 1b. Here, the bite includes the case of biting into the outer peripheral surface of the electric wire constituting the wire harness 1, the case of entering between the electric wires, the case of biting into the outer peripheral surface of the tape for binding the electric wire bundle or the exterior member covering the electric wire bundle. Shall be. However, the small protrusion 50 regulates the rotation and lateral displacement of the wire harness 1b mainly by biting into the outer peripheral surface of the electric wire, the tape, or the outer peripheral surface of the exterior member. Here, the small protrusion 50 is formed in a cylindrical shape having a hemispherical shape at the tip.

  The large protrusion 60 is a portion that suppresses the rotation and movement of the harness clamp 10 relative to the large-diameter wire harness 1a. The large protrusion 60 is located outside the small protrusion 50 with respect to the center in the second direction R on the support surface 28 of the fixed portion 20, and the band portion 30 (the pair of pairs) in the first direction R. It projects from at least one of the two sides of the band insertion hole 45). Here, in the second direction R, the large protrusions 60 are provided at positions on both sides with respect to the center. The large protrusions 60 are provided at positions on both sides of the band portion 30 in the direction along the first direction R. That is, four large protrusions 60 are also provided here.

  More specifically, the large protrusions 60 are provided in the second direction R at intervals smaller than (here, slightly smaller) the diameter (reference dimension (for example, 5 mm)) of the smallest wire harness 1a. It has been.

  The large protrusion 60 is formed in a shape that protrudes larger than the small protrusion 50. More specifically, the large protrusion 60 is set to a size that can bite into the outer peripheral surface of the large-diameter wire harness 1a. The large protrusion 60 regulates rotation and lateral displacement of the wire harness 1a mainly by entering between the electric wires or by biting into the outer surface of the tape or the exterior member covering the electric wire bundle. Here, the large protrusion 60 is formed flat along the first direction R of the wire harness 1, and the tip is formed in an arc shape when viewed from the second direction R. That is, the top of each of the small protrusion 50 and the large protrusion 60 is formed with a curved surface to prevent damage to the wire harness 1.

  A method for applying the harness clamp 10 will be described.

  First, the wire harness 1 is disposed on the support surface 28 along the first direction R. At this time, the wire harness 1 is preferably arranged so that the central axis is located substantially at the center in the second direction R.

  Next, both end portions of the band portion 30 are inserted into the pair of band insertion hole portions 45 in a form in which the intermediate portion in the longitudinal direction of the band portion 30 is wound around the outer peripheral portion of the wire harness 1 on the support surface 28. And the wire harness 1 is clamped and hold | maintained by pulling the both ends of the band part 30 from the insertion direction S front side of the insertion part 22. FIG. Here, when the band part 30 is pulled, the band part 30 is drawn into the pair of band insertion hole parts 45 while abutting the rounding part 46 at the rear end part in the insertion direction S of the fixing part 20. For this reason, the band portion 30 is not bent but is also curved partially or entirely along the curved surface of the rounded portion 46 even at the rear end portion in the insertion direction S of the fixing portion 20.

  In addition, in a state where the band portion 30 is wound in such a manner that the outer peripheral portion of the wire harness 1 is tightened, the pair of band locking portions 40 are respectively locked to any of the plurality of locked portions 32 of the band portion 30. By doing, the state which hold | maintained the wire harness 1 can be maintained.

  As described above, in a state where the band portion 30 is pulled and the outer peripheral portion of the wire harness 1 is tightened, the wire harness 1 is disposed substantially in the center in the second direction R. The wire harness 1 is pressed against the small protrusion 50 or the large protrusion 60 by the band part 30.

  That is, when targeting the large wire harness 1a, the large protrusion 60 bites into the outer periphery of the large wire harness 1a (see FIGS. 5 and 6). FIG. 6 shows a state in which the large protrusion 60 has entered between the wires constituting the large wire harness 1a. Note that the large protrusion 60 may bite into the outer peripheral surface of the electric wire. Moreover, the small protrusion 50 may also be in the state which bite into the outer peripheral part of the wire harness 1a, or the outer peripheral part of the component electric wire.

  Moreover, when targeting the small wire harness 1b, the large sized protrusion 60 bites into the outer peripheral part of the small wire harness 1b (refer FIG. 7, FIG. 8). FIG. 8 shows a state in which the small protrusion 50 has bitten into the outer periphery of the small wire harness 1b in a form in which the small wire harness 1b is sandwiched from both sides. More specifically, the small protrusion 50 bites into the outer peripheral surface of the electric wire constituting the wire harness 1b.

  Then, by inserting the insertion portion 22 into the fixing hole 92 along the insertion direction S, the fixing portion 20 is fixed to the fixing counterpart 90. That is, the locking portion 24 and the presser portion 26 are locked from the front and back of the insertion direction S with respect to the peripheral edge portion of the fixing hole 92. As a result, the portion of the wire harness 1 to which the harness clamp 10 is attached is fixed to the predetermined fixing counterpart 90.

  According to the harness clamp 10 according to the above configuration, the band portion 30 is maintained in a form wound around the outer peripheral portion of the wire harness 1 along the support surface 28 of the fixing portion 20, and the fixing portion 20 is fixed to the fixing mating portion 90. By fixing, the wire harness 1 can be fixed to the fixing counterpart 90. Moreover, the small protrusion 50 which protrudes in the position of at least one of the both sides of the band part 30 in the 1st direction R among the support surfaces 28 of the fixing | fixed part 20, and a small protrusion with respect to the center in the 2nd direction R 50 and a large protrusion 60 projecting larger than the small protrusion 50 at at least one of the two sides of the band section 30 in the first direction R. Correspondingly, the wire harness 1 can be held while restricting rotation and lateral displacement.

  Moreover, according to the structure by which the small protrusion 50 and the large protrusion 60 are each provided in the position of the both sides with respect to the center in the 2nd direction R, while being able to hold | maintain the wire harness 1 with sufficient balance, more reliably wire The rotation and lateral shift of the harness 1 can be regulated.

  Moreover, according to the structure by which the small protrusion 50 and the large protrusion 60 are provided in the position of the both sides of the band part 30 in the 1st direction R, respectively, rotation and a lateral shift of the wire harness 1 can be controlled more reliably. it can.

  Moreover, according to the structure by which the band part 30 is formed separately from the fixing part 20, it becomes a simpler shape and can be easily molded by mold molding. Moreover, the band part 30 is produced by cut | disconnecting the length of the long band material supplied continuously by the length which does not have excess and deficiency corresponding to each harness clamp 10. FIG. For this reason, the surplus part (part cut off) of a band material hardly arises, and waste of material can be omitted.

  In addition, the fixing portion 20 has a pair of band insertion hole portions 45 that are adjacent to each other in the second direction R and penetrate from the support surface 28 to the opposite surface and can be inserted through the band portion 30. The stop portions 40 are respectively provided in the pair of band insertion hole portions 45, and the pair of band insertion hole portions 45 are respectively formed with rounded portions on the outer edge portions in the second direction R among the opening edge portions of the support surface 28. Therefore, when the band part 30 is passed through the pair of band insertion hole parts 45 and the wire harness 1 is held, the band part 30 is suppressed from being bent, and the tightening operation can be performed efficiently.

  So far, the harness clamp 10 has been described with an example in which the band locking portion 40 is provided in the pair of band insertion hole portions 45 formed in the fixing portion 20 and the band portion 30 is formed separately from the main body portion. However, the configuration is not limited to this. For example, a convex portion formed with a band insertion hole portion penetrating in the second direction is provided on the support surface 28, and the band portion of the binding band is passed through the band insertion hole portion so as to tighten and hold the wire harness. It may be configured. The binding band includes a band portion in which a plurality of locked portions are formed in the longitudinal direction and a locking housing portion that is inserted through the band portion and can be locked to the locked portion. The stop portion selectively locks to the plurality of locked portions, thereby allowing the circumferential length of the annular portion formed by the band portion to be adjusted and maintained. In addition, it is possible to adopt a configuration in which the binding housing portion of the binding band is provided on the support surface 28 and is integrally formed as the entire harness clamp.

  Moreover, although the example where four small protrusions 50 and four large protrusions 60 are provided has been described, one or a plurality other than four may be provided. For example, the small protrusion 50 and the large protrusion 60 may be provided only on one side of the band insertion hole 45 in the insertion direction S or only on one side with respect to the center in the direction orthogonal to the insertion direction S. That is, the small protrusion 50 and the large protrusion 60 do not interfere with the band section 30 and are provided at positions that bite into the outer periphery of the small wire harness 1b or the large wire harness 1a, respectively. Various selections can be made.

  As mentioned above, although the harness clamp 10 was demonstrated in detail, above-described description is an illustration in all the situation, Comprising: 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.
