Description

  The present invention relates to a technique for covering and protecting a wire harness with a protector.

  Patent document 1 is disclosing the electric wire biting prevention structure of the protector fixed to a connector. In Patent Document 1, the protector is configured by a pair of halves. An electric wire biting prevention column is erected on one half body, and the electric wire biting prevention column prevents the electric wire from climbing on the edge of the one half body. The electric wire is prevented from biting between the split bodies.

JP-A-11-89046

  However, according to the protector disclosed in Patent Document 1, since the electric wire biting column protrudes from the edge of one half body, it interferes with the wiring work of the wire harness.

  Moreover, there is a possibility that the wire harness is disposed outside the electric wire biting column, and in that case, the electric wire may be bitten.

  Therefore, an object of the present invention is to prevent the wire harness from being obstructed when the wire harness is inserted into the protector, and to more reliably suppress the electric wire from being pinched.

  In order to solve the above-described problem, a protector according to a first aspect includes a bottom portion and a pair of side wall portions erected on the bottom portion, and the pair of side walls is provided at at least one tip portion of the pair of side wall portions. The guide surface which inclines in the base end side toward between the side wall parts of this is provided.

In the first aspect, at least one of the pair of side wall portions includes a plate-like portion rising from the bottom portion, and a protrusion protruding from the plate-like portion toward the pair of side wall portions. The protruding portion extends over the entire protruding direction of the plate-shaped portion, and the guide surface is formed at a distal end portion of the protruding portion on the leading end side in the protruding direction of the plate-shaped portion. It is what.

A 2nd aspect is a protector which concerns on a 1st aspect, Comprising: The said guide surface is formed also in the front-end | tip part of the said plate-shaped part.

A 3rd aspect is a protector which concerns on the 1st or 2nd aspect, Comprising: The angle of 90 degree | times or more is made to the front-end | tip part of the said plate-shaped part with respect to the said guide surface and the outer surface of the said plate-shaped part. In other words, a continuous surface is formed through a curved surface.

The first aspect, before Symbol pair of side wall portions is erected at a distance so as to form a flex path, located inside the said path flexing of the pair of side wall portions The thing is provided with the guide surface.

A 4th aspect is provided with the protector which concerns on any one 1st- 3rd aspect, and the wire harness arrange | positioned between said pair of side wall parts.

According to the first to fourth aspects, since at least one distal end portion of the pair of side wall portions is provided with a guide surface that is inclined toward the proximal end side between the pair of side wall portions, Can be guided between the pair of side wall portions, and pinching of the electric wire can be suppressed more reliably. Further, the guide surface is unlikely to interfere with the wire harness arrangement work.

According to the 1st aspect, pinching of an electric wire can be suppressed more reliably by the guide surface formed in the front-end | tip part of a protrusion.

According to the 2nd aspect, an electric wire can be guided toward a pair of side wall part also in the front-end | tip part of a plate-shaped part, and pinching of an electric wire can be suppressed more reliably.

According to the 3rd aspect, even if an electric wire is inserted | pinched between a plate-shaped part and another member, the damage of an electric wire can be suppressed.

When arranging an electric wire between a pair of side wall parts, an electric wire tends to get on the side wall part located inside in the curved path. Therefore, as in the first aspect, by providing the guide surface on the side wall portion located on the inner side in the curved path, the pinching of the electric wire can be effectively suppressed.

  Hereinafter, the protector and the wire harness with protector according to the embodiment will be described. FIG. 1 is a perspective view showing the protector 20, and FIG. 2 is a partially enlarged view of FIG. 3 and 4 are perspective views showing the wire harness with protector 10, and FIG. 5 is a partially enlarged view of FIG. 3 to 5, the wire harness 12 being inserted into the protector 20 is illustrated.

  The wire harness with protector 10 includes a protector 20 and a wire harness 12.

  The wire harness 12 includes at least one electric wire. Here, the wire harness 12 is a bundle of a plurality of electric wires, and is used as a wiring material that is routed in a vehicle or the like and electrically connects various electrical components. The wire harness 12 may be branched on the way. Further, the wire harness 12 may include an optical fiber cable or the like. Here, the part accommodated in this protector 20 among the wire harness 12 is maintained in the state bundled by the binding member. As the binding member, an adhesive tape, a binding band, or the like is used. A portion of the wire harness 12 accommodated in the protector 20 may be maintained in a state of being bundled by a bundling member at a partial location in the longitudinal direction, or the bundling member as a whole in the longitudinal direction. May be bound together. 3-5, the outline of the wire harness 12 in which the some electric wire was bundled is drawn.

  In the state where the wire harness 12 is housed in the protector 20, a binding member such as an adhesive tape is attached to the protector 20 and the wire harness 12, or a lid is attached to the protector 20, and the protector 20 and the wire harness. 12 is preferably maintained in an integrated state.

  The protector 20 is a component integrally molded with resin and includes a bottom portion 22 and side wall portions 30 and 35. The wire harness 12 is accommodated in the protector 20. The protector 20 plays a role of protecting the wire harness 12 while maintaining the wire harness 12 along a predetermined path shape. Here, although protector 20 demonstrates by the example which protects the part where wire harness 12 was bundled in one form, it may protect the part branched among wire harnesses. In this case, the protector may be formed in a shape corresponding to the branch path.

  The bottom 22 is formed in an elongated plate shape. Here, the bottom portion 22 is formed in an elongated plate shape that bends in an arc shape in plan view. Both end portions of the bottom portion 22 extend linearly, but this portion may be omitted. Moreover, the shape which curves in L shape may be sufficient as a bottom part, and the shape extended linearly may be sufficient as it. Although the bottom part 22 is formed in the same width in the whole extension direction, the width | variety may be fluctuate | varied on the way.

  The side wall portions 30 and 35 are erected on both side portions of the bottom portion 22 and extend to one main surface side (the upper side in FIG. 1 and the like) of the bottom portion 22. More specifically, the side wall portion 30 is erected on the outer side portion of both side portions of the bottom portion 22. Further, a side wall portion 35 is erected on the inner side portion of both side portions of the bottom portion 22. And a pair of side wall part 30 and 35 is standingly arranged at intervals so that the path | route (here the path | route curved in an arc shape) may be formed.

  In this protector 20, openings are formed at both ends in the extending direction, and the wire harness 12 accommodated in the protector 20 extends outward from both ends of the protector 20 through the opening. In addition, an accommodation opening is formed on the distal end side of the pair of side wall portions 30 and 35 (that is, the side opposite to the bottom portion 22), and the wire harness 12 passes through the accommodation opening and is on the bottom portion 22 to form a pair. Between the side wall portions 30 and 35.

  In addition, a guide surface 38f that is inclined toward the base end side between the pair of side wall portions 30 and 35 is formed at at least one distal end portion of the pair of side wall portions 30 and 35.

  Here, a guide surface 38f is formed on the side wall 35 located on the inner side in the curved path of the pair of side walls 30, 35.

  More specifically, the side wall portion 35 includes a plate-like portion 36 that rises from the bottom portion 22, and a protrusion 38 that protrudes from the plate-like portion 36 between the pair of side wall portions 30 and 35.

  The plate-like portion 36 is formed in a plate shape formed along the inner side portion of the bottom portion 22. The front end portion of the plate-like portion 36 is formed on a surface perpendicular to the extending direction of the plate-like portion 36, in other words, a surface 36 f parallel to the bottom portion 22. Thus, the surface 36f is continuous with the guide surface 38f and the outer surface of the plate-like portion 36 at an angle of 90 degrees or more. Specifically, the surface 36f is continuous with an obtuse angle with respect to the guide surface 38f, and is connected with the outer surface of the plate-like portion 36 with an angle of 90 degrees.

  The protrusion 38 is provided at an intermediate portion in the extending direction of the inner surface of the plate-like portion 36. Here, a plurality (three in this case) of protrusions 38 are provided at intervals in the extending direction of the plate-like part 36. More specifically, one protrusion 38 is provided at the central portion in the extending direction of the arc-shaped portion of the plate-like portion 36, and two protrusions 38 are provided at positions spaced from this.

  The protrusion 38 is formed in a plate shape extending along the protruding direction of the plate-like portion 36. The protrusion 38 protrudes in a vertical posture with respect to the tangential plane of the inner surface of the plate-like portion 36 where the protrusion 38 protrudes.

  The protruding portion 38 extends over the entire protruding direction of the plate-like portion 36, and the protruding portion intermediate portion and the base end portion of the plate-like portion 36 are formed with the same protruding dimensions. A portion of the protrusion 38 on the front end side in the protruding direction of the plate-like portion 36 is formed on a guide surface 38 f that is inclined toward the base end side between the pair of side wall portions 30 and 35. Here, the guide surface 38f is formed so as to incline linearly, but may be formed to incline while curving outward or inward.

  The side wall portion 30 includes a plate-like portion 32 that rises from the bottom portion 22. The plate-like portion 32 is formed in a plate shape formed along the outer side portion of the bottom portion 22.

  The wire harness 12 is inserted into the protector 20 configured as described above through the accommodation opening. It is assumed that when the wire harness 12 is inserted, the wire harness 12 is on the side wall portion 35. In particular, the wire harness 12 extends linearly in the initial state, and when the wire harness 12 is inserted into the protector 20, it is inserted between the pair of side wall portions 30 and 35 while bending the wire harness 12. Therefore, it tends to be in a state where it rides on the side wall portion 35 inside the route of the turn. However, as shown in FIG. 6, when the wire harness 12 is pushed toward the bottom portion 22 from the state where the wire harness 12 rides on the side wall portion 35 (see arrow F in FIG. 6), the wire harness 12 is Then, it contacts the guide surface 38f and is guided toward the pair of side wall portions 30 and 35 (see arrow A in FIG. 6). For this reason, by pushing the wire harness 12 toward the bottom portion 22, the state where the wire harness 12 rides on the side wall portion 35 is easily eliminated, and the wire harness 12 can be easily moved between the pair of side wall portions 30 and 35. Can be accommodated.

  For this reason, the lid is attached to the protector 20 so as to close the accommodation opening, or the protector 20 is attached to the attachment target portion of the vehicle body, and the accommodation opening is closed by the attachment target portion. It becomes difficult for the wire harness 12 to be sandwiched between the side wall portion 35 and the lid portion or the attachment target portion.

  Thereby, pinching of the electric wire contained in the wire harness 12 can be suppressed more reliably.

  Further, the guide surface 38f does not protrude beyond the housing opening of the protector 20, but rather is recessed inside the housing opening. For this reason, it is difficult to disturb the arrangement work when the wire harness 12 is wired while being inserted into the protector 20.

  Further, since the guide surface 38f is guided between the pair of side wall portions 30 and 35 by the guide surface 38f formed at the distal end portion of the protrusion 38, the wire is more inward with respect to the plate-like portion 36. Can be guided to different positions. For this reason, for example, even if some electric wires included in the wire harness 12 are scattered, it is difficult to get on the side wall portion 35. For this reason, pinching of the electric wire contained in the wire harness 12 can be suppressed more reliably.

  In addition, a surface 36 f is formed at the tip of the plate-like portion 36 and is continuous at an angle of 90 degrees or more with respect to the guide surface 38 f and the outer surface of the plate-like portion 36. Specifically, the entire surface of the tip portion of the plate-like portion 36 is formed as a surface perpendicular to the plate-like portion 36. For this reason, it is difficult to form a pointed portion at the tip of the side wall portion 35. Thereby, even if an electric wire is inserted | pinched between the front-end | tip part of the plate-shaped part 36, a cover part, or an attachment object site | part, damage to an electric wire can be suppressed effectively.

  Moreover, since the guide surface 38f is provided in the side wall part 35 located inside in the curved path | route, pinching of an electric wire can be effectively suppressed by the side wall part which an electric wire can easily get on.

  On the other hand, with respect to the side wall portion 30 located on the outer side in the curved path, the configuration is such that the guide surface 38f is not provided (the configuration in which the protrusion 38 is not provided), thereby simplifying the shape and the pair of side wall portions 30, The compression of the accommodation space of the wire harness 12 between 35 can be suppressed. But the guide surface may be provided also in the side wall part located in the outer side in the curved path.

  In the above-described embodiment, the surface 36f of the distal end portion of the plate-like portion 36 of the side wall portion 30 has been described as an example in which the guide surface 38f and the outer surface of the plate-like portion 36 are formed at an angle of 90 degrees or more. However, as shown in FIG. 7, the surface 136f of the tip of the plate-like portion 136 corresponding to the plate-like portion 36 is connected to the guide surface 38f and the outer surface of the plate-like portion 136 via the curved surface R. Also good. Even in this case, it is possible to suppress the damage of the electric wire due to the pinching between the plate-like portion 136 and the lid portion or the attachment target portion.

  Moreover, in the said embodiment, although the whole tip part of the plate-shaped part 36 of the side wall part 30 demonstrated in the example which is the surface 36f perpendicular | vertical with respect to the protrusion direction of the plate-shaped part 36, as shown in FIG. The guide surface 236fg may also be formed at the tip of the plate-like portion 236 corresponding to the plate-like portion 36. In the example shown in FIG. 8, a portion from the inner side of the tip portion of the plate-like portion 236 is formed on a guide surface 236 fg continuous with the guide surface 38 f formed on the protrusion 38. Further, a portion from the outside of the tip portion of the plate-like portion 236 is formed on a surface 236fa perpendicular to the protruding direction of the plate-like portion 236.

  Thereby, even when the wire harness 12 rides on the plate-like part 236 in a state where the center O of the wire harness 12 is located outside the inner side surface of the plate-like part 236, the wire harness 12 is effective. Can be guided inside the plate-like portion 236 (see arrow A).

  In addition, the whole front-end | tip part of the plate-shaped part 236 may be formed in the guide surface. However, in the example shown in FIG. 8, since the surface 236fa is continuous with the guide surface 236fg and the outer surface of the plate-like portion 236 at an angle of 90 degrees or more, the sharp portion can be eliminated as much as possible, and the wire is damaged. Can be effectively suppressed.

  In the above embodiment, the guide surface 38f is formed at the tip of the protrusion 38. However, as shown in FIG. 9, the side wall 335 corresponding to the side wall 35 has a plate shape rising from the bottom. Although the portion 336 is provided, the protrusion 38 is omitted, and a guide surface 336 fg may be formed at the tip of the plate-like portion 336.

  Here, a portion from the inside of the tip portion of the plate-like portion 336 is formed on the guide surface 336fg. Further, the outer portion of the tip of the plate-like portion 336 is formed on a surface 336fa perpendicular to the protruding direction of the plate-like portion 336.

  Even in this case, the wire harness 12 can be guided inside the plate-like portion 336 by the guide surface 336fg. In particular, even when the wire harness 12 rides on the plate-like portion 336 in a state where the center O of the wire harness 12 is located outside the inner surface of the plate-like portion 336, the wire harness 12 is effectively used. It can guide inside the plate-shaped part 336 (refer arrow A).

  In addition, the whole front-end | tip part of the plate-shaped part 336 may be formed in the guide surface. However, in the example shown in FIG. 9, the surface 336fa is continuous with the guide surface 336fg and the outer surface of the plate-like portion 336 at an angle of 90 degrees or more, so that a sharp portion can be eliminated as much as possible, and the electric wire is damaged. Can be effectively suppressed.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  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.
