  Hereinafter, the protector for wire harnesses which concerns on embodiment is demonstrated. 1 is a partial perspective view showing a wire harness protector 20 according to the embodiment, FIG. 2 is a partial plan view showing the wire harness protector 20, and FIG. 3 is a front view showing the wire harness protector 20. As shown in FIG. FIG. 4 is an explanatory view showing a state in which the locking portion 30 is locked to the wire harness 10.

  The wire harness protector 20 is a member that accommodates the wire harness 10 and performs path regulation, protection, and the like. The wire harness 10 is a component in which a plurality of electric wires are bundled, and is routed through an interior part (for example, interior panel) of an automobile and connects various electrical parts mounted on the automobile. Used as The wire harness 10 may be appropriately branched according to the wiring form to the automobile. Further, an optical fiber or the like may be bound to the wire harness 10.

  The wire harness protector 20 includes a protector body 22. The protector body 22 is a member formed of resin or the like, and includes a bottom 24, a pair of side walls 26, and a pair of locking portions 30.

  Here, the bottom 24 is formed in an elongated plate shape. Further, a pair of side wall portions 26 projecting toward one main surface of the bottom portion 24 are formed on both side portions of the bottom portion 24. Further, a wire harness housing space 23 </ b> S capable of housing the wire harness 10 is formed between the pair of side wall portions 26 on the one main surface side of the bottom portion 24. The wire harness accommodating space 23S is formed in an elongated groove-like space, and the wire harness 10 is accommodated along the extending direction thereof. An opening 23 </ b> P is formed at one end of the pair of side wall portions 26. That is, the wire harness housing space 23S communicates with the outside through the opening 23P. And the wire harness 10 accommodated in the wire harness accommodating space 23S extends outside through the opening 23P.

  A pair of hole portions 24h is formed in a region corresponding to a region where the pair of locking portions 30 are formed in the bottom portion 24. The pair of holes 24h is used as a space for removing a mold part for molding the pair of locking parts 30.

  A lid may be placed on the opening of the protector body 22 opposite to the bottom 24. The lid portion may be a separate body from the protector main body portion 22, or may be connected to be openable / closable via a hinge or the like.

  Moreover, the shape which forms the wire harness accommodating space to bend may be sufficient as the bottom part and a pair of side wall part of the protector main-body part 22, and the shape which forms the wire harness accommodating space to branch may be sufficient as it. Moreover, the opening which extends a wire harness outside may be formed besides the above-mentioned location.

  A pair of locking portions 30 are formed on the inner surfaces of the pair of side wall portions 26. A pair of latching | locking part 30 is formed in the same position in the longitudinal direction and protrusion direction of a pair of side wall part 26, and has opposed in the width direction of the wire harness accommodating space 23S. Therefore, when the wire harness 10 is disposed between the pair of locking portions 30, the pair of locking portions 30 are locked to the wire harness 10 from both sides of the same position in the longitudinal direction of the wire harness 10.

  Each locking portion 30 includes an elastic support portion 32 and a plurality of locking claws 34 and 36. The plurality of locking claws 34 and 36 are portions that lock the outer periphery of the wire harness 10 disposed in the wire harness housing space 23S, and the elastic support portion 32 wire the plurality of locking claws 34 and 36 to each other. It has a role of urging so as to press against the outer peripheral portion of the harness 10.

  That is, the plurality of locking claws 34 and 36 are along the direction from the opening 23P toward the inside of the wire harness housing space 23S (that is, the extending direction of the wire harness 10 disposed in the wire harness housing space 23S). It is provided so that it may line up at intervals. Therefore, the plurality of locking claws 34 and 36 abut against the wire harness 10 at a plurality of locations along the longitudinal direction. The distal end portions of the plurality of locking claws 34 and 36 are formed in a shape that gradually becomes thinner toward the distal end side to some extent within a range in which the wire harness 10 is not damaged. Here, the front ends of the plurality of locking claws 34 and 36 are slightly rounded.

  Moreover, each latching claw 34 and 36 is extended so that the protrusion direction (namely, direction orthogonal to the extension direction of the wire harness 10 arrange | positioned in the wire harness accommodating space 23S) of the side wall part 26 may be extended. Is formed. Accordingly, the plurality of locking claws 34 and 36 abut against the wire harness 10 in a posture orthogonal to the longitudinal direction.

  Moreover, the elastic support part 32 supports the some latching claws 34 and 36 so that it can advance / retreat toward the center of the width direction of the wire harness accommodating space 23S with its own elastic force. Here, the elastic support portion 32 includes a proximal end portion 32a protruding from the inner surface of the side wall portion 26 and a distal end portion 32b extending from the distal end portion of the proximal end portion 32a. The base end side portion 32a protrudes from the inner surface of the side wall portion 26 toward the center in the width direction of the wire harness accommodating space 23S. The distal end side portion 32b is directed from the outside of the wire harness 10 toward the inside of the wire harness housing space 23S from the opening 23P (that is, along the extending direction of the wire harness 10 disposed in the wire harness housing space 23S). It is an inclined part inclined toward the center side in the width direction of the wire harness housing space 23S (that is, the center side of the pair of side wall portions 26). The elastic support portion 32 is elastically deformed so as to swing around the base end side portion 32a. The proximal end portion 32a is formed thinner than the distal end portion 32b, and the distal end portion 32b is formed so as to be gradually thinner toward the proximal end portion 32a. Accordingly, the elastic support portion 32 is more easily elastically deformed with the base end side portion 32a as the center.

  The plurality of locking claws 34, 36 are provided on the surface of the distal end portion 32 b of the elastic support portion 32 facing the wire harness accommodating space 23 </ b> S. Among the plurality of locking claws 34 and 36, the one provided on the most distal end side of the elastic support portion 32 is the first locking claw 34, and the one provided on the proximal end side more than that is a plurality (here, Two) second locking claws 36.

  The first locking claw 34 is inclined in the same direction as the distal end portion 32 b of the elastic support portion 32. That is, the 1st latching claw 34 inclines in the width direction center side of the wire harness accommodating space 23S toward the inner side of the wire harness accommodating space 23S from the opening 23P.

  The second locking claw 36 is inclined in the direction opposite to the inclination direction of the distal end side portion 32 b of the elastic support portion 32. That is, the 2nd latching claw 36 inclines to the width direction center side of the wire harness accommodating space 23S toward the opening 23P side from the wire harness accommodating space 23S. Although the said inclination direction is defined in the state which does not accommodate the wire harness 10, even if the state which accommodated the wire harness 10, ie, the state which the latching claws 34 and 36 are latching to the wire harness 10, It is preferable that it is in the same inclined state as.

  Further, a plurality (two in this case) of the second locking claws 36 are provided, and therefore, a larger number than the first locking claws 34 are provided. A plurality of first locking claws 34 may be provided, and even in this case, it is preferable that a larger number of second locking claws 36 are provided than the first locking claws 34.

  The plurality of locking claws 34, 36 protrude in large order sequentially toward the center in the width direction of the wire harness housing space 23 </ b> S in the order from the opening 23 </ b> P to the inside of the wire harness housing space 23 </ b> S. When the wire harness 10 is disposed between the pair of locking portions 30 and each elastic support portion 32 is elastically deformed so as to swing around the base end side portion 32a, the wire harness housing space 23S The projecting dimensions of the plurality of locking claws 34 and 36 in the width direction are approximately the same, and are pressed against the outer peripheral portion of the wire harness 10 with substantially equal force. However, depending on the thickness of the wire harness 10, it is not essential that the above is established, and it is sufficient that at least two locking claws 34 and 36 abut on the outer peripheral portion of the wire harness 10.

  Further, of the tip portions (tip portions extending along the protruding direction of the side wall portion 26) of the plurality of locking claws 34, 36, the portion on the opposite side to the bottom portion 24 faces the opening on the opposite side to the bottom portion 24. And is formed on a guide surface 34g extending outward. Here, the guide surface 34g is formed on a flat slope, but may be a curved surface or the like.

  A procedure for housing the wire harness 10 in the wire harness protector 20 will be described.

  First, the wire harness 10 is pushed between the pair of locking portions 30 from above between the pair of locking portions 30. Then, the outer peripheral portion of the wire harness 10 is pressed against the pair of guide surfaces 34 g and guided toward the space between the pair of locking portions 30.

  When the wire harness 10 is further pushed in, the outer peripheral portion of the wire harness 10 is pressed against the pair of guide surfaces 34g, so that the pair of locking portions 30 are elastically pushed away from both sides of the wire harness housing space 23S. Deform. And the space which can accommodate the wire harness 10 between the some latching claws 34 and 36 of both sides is formed.

  When the wire harness 10 is pushed in until it reaches the bottom 24, the outer peripheral portion of the wire harness 10 comes into sliding contact with the plurality of locking claws 34 and 36 along the longitudinal direction thereof, and the longitudinal direction of the locking claws 34 and 36. Reach the middle part. Thereby, it will be in the state which the some latching claws 34 and 36 latched from the both sides of the wire harness 10, and the wire harness 10 is fixed with respect to the protector 20 for wire harnesses. Thereafter, attachment of a lid or the like is performed as necessary.

  In addition, the effect | action which accommodates the other part in the wire harness 10 in the wire harness accommodating space 23S may be performed before the said pinching operation | work, and may be performed after it.

  In order to prevent the wire harness 10 from being pulled out while the wire harness 10 is pushed between the plurality of locking claws 34 and 36 on both sides as described above, a part of the plurality of locking claws 34 and 36 or An embossing process may be applied to all the tip portions.

  According to the wire harness protector 20 configured as described above, when the wire harness 10 is disposed in the wire harness housing space 23S, the side wall 26 is projected in the extending direction of the plurality of locking claws 34, 36. If the wire harness 10 is pushed between the pair of locking portions 30 along the direction, the plurality of locking claws 34 and 36 are pressed against the outer peripheral portion of the wire harness 10 by the elastic force of the elastic support portion 32. At this time, since the plurality of locking claws 34 and 36 are locked to the outer peripheral portion of the wire harness 10 at a plurality of locations in the longitudinal direction of the wire harness 10, the wire harness 10 can be positioned and fixed more reliably in the longitudinal direction. Therefore, parts such as an adhesive tape or a tie band and their attachment work, and even the wire harness 10 without the corrugated tube, can be more securely fixed to a fixed position with respect to the wire harness protector 20. .

  If necessary, reinforcing fixing with an adhesive tape or a tie band may be performed. But the direction which abbreviate | omitted these fixed structures becomes easy for the fixed structure and fixing operation | work of the wire harness 10. Further, the wire harness 10 may be externally provided with a corrugated tube.

  Moreover, since the wire harness 10 can be easily positioned and fixed along the longitudinal direction by pushing the wire harness 10 between the plurality of locking claws 34 and 36 on both sides, the wire harness extending from the wire harness protector 20 10 dimension management is also facilitated.

  Moreover, since the pinching of the wire harness 10 is performed by the pair of locking portions 30 formed on the pair of side wall portions 26, it is possible to prevent the attachment work of the lid portion and the like from being affected. .

  In addition, since the elastic support portion 32 includes the tip side portion 32b that is inclined as described above, the wire harness 10 is pulled in the direction of being pulled out from the protector main body portion 22 and is engaged with the outer peripheral portion of the wire harness 10. When the entire pawl 34 is pulled in the pull-out direction, the elastic support portion 32 is elastically deformed so as to swing around the base end side portion 32a. Then, the whole of the plurality of locking claws 34 and 36 moves to the center side in the width direction of the wire harness housing space 23 </ b> S and is pressed more strongly against the wire harness 10. Further, since the first locking claw 34 is provided on the distal end side of the elastic support portion 32 and is inclined in the same direction as the distal end side portion 32b of the elastic support portion 32, the plurality of locking claws 34, 36 are provided. When moving to the center side in the width direction of the wire harness housing space 23 </ b> S, the first locking claws 34 bite more strongly into the outer peripheral portion of the wire harness 10. For this reason, the wire harness 10 can be more reliably fixed to a fixed position with respect to the drawing-out direction of the wire harness 10.

  In particular, there is a strong possibility that a large force acts in the pull-out direction on the wire harness 10 extending from the wire harness protector 20. Therefore, as described above, it can be said that it is effective to provide the first locking claw 34 at the distal end portion of the elastic support portion 32 and receive the force in the pulling direction.

  In addition, with respect to the wire harness 10 extended from the protector 20 for wire harnesses, a force may act on the pushing direction.

  Therefore, when the second locking claw 36 inclined in the direction opposite to the first locking claw 34 is provided and a force in the pushing direction is applied to the wire harness 10, the second locking claw 36 is connected to the wire harness 10. The wire harness can be more securely fixed at a certain position even in the pushing direction of the wire harness 10 by causing the wire harness to be strongly bitten into the outer periphery of the wire harness 10.

  However, if the first locking claw 34 is provided at the distal end portion of the elastic support portion 32 as described above and the first locking claw 34 is strongly pressed against the outer peripheral portion of the wire harness 10, There is a possibility that the force with which the two locking claws 36 are pressed against the outer peripheral portion of the wire harness 10 is weakened.

  Therefore, by providing a plurality of the second locking claws 36, the wire harness 10 can be more reliably fixed at a fixed position in the pushing direction.

  In the first embodiment, the same number of the first locking claws and the second locking claws may be provided, and more first locking claws are provided than the second locking claws. It may be done. Moreover, the structure in which only the 1st latching claw was provided may be sufficient, and the structure in which only the 2nd latching claw was provided may be sufficient. Moreover, all or some of the plurality of locking claws may protrude without inclining from the inner surface of the side wall portion toward the center portion in the width direction of the wire harness housing space 23S.

  Moreover, since the part on the opposite side to the bottom part 24 among the front-end | tip parts of the some latching claws 34 and 36 is formed in the guide surface 34g which inclines outside toward the opposite side to the bottom part 24, a wire harness 10 can be easily pushed between the plurality of locking claws 34 and 36 on both sides.

  In addition, it is not essential that the elastic support part 32 inclines and each latching claw 34 and 36 incline like the said embodiment.

  In the wire harness protector 120 according to the modification shown in FIGS. 5 and 6, the following pair of locking portions 130 is provided instead of the pair of locking portions 30.

  That is, each locking portion 130 includes an elastic support portion 132 and a plurality of locking claws 134.

  The plurality of locking claws 134 are provided so as to be arranged at intervals from the opening 23P toward the wire harness accommodating space 23S (along the extending direction of the wire harness 10). Here, each latching claw 134 is provided on both sides of the inward surface of the plate-like base portion 135 disposed along the extending direction of the wire harness 10. Each locking claw 134 is formed in a ridge shape extending along the protruding direction of the side wall portion 26. Here, each locking claw 134 protrudes substantially straight from the base portion 135 toward the intermediate portion in the width direction of the pair of side wall portions 26 without being inclined. Moreover, each latching claw 134 is formed in the shape which becomes thin gradually toward the front end side. Further, a guide surface 134g similar to the guide surface 34g is formed on a portion of the locking claw 134 on the side opposite to the bottom 24.

  The elastic support portion 132 has a pair of leg portions 132 a that support the plurality of locking claws 134 so as to be elastically deformable on both sides in the extending direction of the wire harness 10. Here, the pair of leg portions 132 a is provided on both side portions of the base portion 135, and connects both side portions of the base portion 135 and the inner surface of the side wall portion 26. Each leg 132a has a thin portion 132b that is easily elastically deformed.

  Also in this modified example, when the wire harness 10 is disposed between the plurality of locking claws 134 on both sides, as in the above embodiment, the locking claws 134 are arranged at a plurality of locations in the longitudinal direction of the wire harness 10. The wire harness 10 can be positioned and fixed in the longitudinal direction by engaging with the outer peripheral portion.

  In this modification, when the wire harness 10 is disposed between the plurality of locking claws 134 on both sides, the pair of leg portions 132a are elastically deformed in substantially the same manner. For this reason, the plurality of locking claws 134 on each side can be moved back and forth with respect to the wire harness 10 in the original parallel state. For this reason, even if the wire harnesses 10 having different outer diameters are disposed, the plurality of locking claws 134 are pressed against the outer peripheral portion of the wire harness 10 in a substantially similar state. Therefore, even if the outer diameter of the wire harness 10 is different, the wire harness 10 can be positioned in the longitudinal direction in the same manner, and the versatility with respect to the different outer diameter of the wire harness 10 is excellent.

  In the wire harness protector 220 according to the modification shown in FIGS. 7 and 8, the following pair of locking portions 230 is provided instead of the pair of locking portions 30.

  That is, each locking portion 230 includes an elastic support portion 232 and a plurality of locking claws 234.

  The plurality of locking claws 234 are projected from the base portion 235, and the configuration relating to this portion is the same as that of the locking claws 134 and the base portion 135 of the above modification.

  Further, the elastic support portion 232 extends from the distal end portion (opening side opposite to the bottom portion) of the side wall portion 26 toward the base end portion (bottom portion side) so as to incline toward the center in the width direction of the wire harness accommodating space 23S. ing. The plurality of locking claws 234 are provided along with the base 235 at the tip. Here, the guide surface 234g formed on the locking claw 234 is inclined at the same degree as the inclination of the elastic support portion 232, and therefore the guide surface 234g and the outer surface of the elastic support portion 232 are flush with each other. Yes.

  In addition, the elastic support part may extend so as to incline in the direction opposite to the above, that is, incline toward the center side in the width direction of the wire harness housing space 23S from the base end part of the side wall part toward the distal end side. .

  Also in this modified example, when the wire harness 10 is disposed between the plurality of locking claws 234 on both sides as in the above embodiment, the locking claws 234 are attached to the wire harness 10 at a plurality of locations in the longitudinal direction of the wire harness 10. The wire harness 10 can be positioned and fixed in the longitudinal direction by engaging with the outer peripheral portion.

  In this modification, when the wire harness 10 is disposed between the plurality of locking claws 234 on both sides, the elastic support portion 232 is elastically deformed so as to approach the inner surface while maintaining a parallel state with respect to the inner surface of the side wall portion 26. To do. For this reason, the plurality of locking claws 234 on each side can be moved back and forth with respect to the wire harness 10 in the original parallel state. For this reason, even if the wire harnesses 10 having different outer diameters are disposed, the plurality of locking claws 234 are pressed against the outer peripheral portion of the wire harness 10 in a substantially similar state. Therefore, even if the outer diameter of the wire harness 10 is different, the wire harness 10 can be positioned in the longitudinal direction in the same manner, and the versatility with respect to the different outer diameter of the wire harness 10 is excellent.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts. For example, in each of the above modifications, the locking claws 134 and 234 may be inclined as described in the above embodiment.
