Description

  The present invention relates to a wire harness protector that holds a wire harness and is fixed to an attachment member such as a vehicle body panel.

  Conventionally, a wire harness protector that holds a wire harness and is fixed to a member to be attached such as a vehicle body panel (hereinafter, referred to as a protector as appropriate) has been used for path regulation and strengthening of the protection function of electric wires. At a required routing location, a clip portion protruding integrally with the protector is inserted and locked in a locking hole drilled in the vehicle body panel. For example, as described in Japanese Patent Application Laid-Open No. 2006-6087 (Patent Document 1), a protector for a wire harness includes a protector main body through which the wire harness is inserted, a lid that covers an opening of the protector main body, a vehicle body panel, and the like. And a clip portion fixed to the attached member.

  By the way, when the clip portions of the protectors provided in a plurality at the required pitch in the longitudinal direction of the wire harness are fitted into the locking holes formed in the vehicle body panel at the same pitch, the interval between the clip portions and the locking holes of the vehicle body panel In some cases, a dimensional error occurs due to a manufacturing intersection between the gaps and it is difficult to fit the clip portion. In order to absorb this dimensional error, for example, FIG. 2 of Japanese Patent Application Laid-Open No. 2012-228029 (Patent Document 2) discloses a structure in which the clip portion can be moved in the longitudinal direction with respect to the harness mounting portion. ing.

  However, since the slide rail part and the connecting part for enabling the clip part to move in the longitudinal direction with respect to the harness attaching part are provided to protrude outward from the wire harness, the slide rail part and the connecting part are provided. There is a possibility that the portion or the like interferes with other members and it is difficult to move in the longitudinal direction. In addition, since the slide rail portion and the like are provided so as to protrude outside the protector body, there are cases where the request for downsizing cannot be met, for example, when the installation space is limited.

  The present invention has been made in the background of the above-described circumstances, and the problem to be solved is that the clip portion and the vehicle body panel can be bent and deformed in the longitudinal direction without causing a problem of interference with other members. An object of the present invention is to provide a protector for a wire harness having a novel structure that can absorb a dimensional error with respect to a locking hole drilled in the space and can be disposed efficiently.

  A first aspect of the present invention is a protector for a wire harness that is inserted and held in a wire harness and fixed to a member to be attached. The protector main body extends in a bowl shape and can accommodate the wire harness in an inserted state. A lid that covers the opening of the protector main body, and a clip portion that is attached and fixed to the attached member, the clip portion on the outer surface of at least one of the protector main body or the lid body And is connected via a bending part that can be bent and deformed in the longitudinal direction, and the bending part is housed in the protector body.

  According to this aspect, the clip portion is connected to the protector body or the lid body via the bending portion that can be bent and deformed in the longitudinal direction. In other words, since the clip portion connected to the bending portion can be deformed in the longitudinal direction of the protector body, it is possible to absorb a dimensional error generated between the clips and between the locking holes formed in the vehicle body panel. it can.

  Moreover, the bending portion is provided so as to protrude from the protector body. Accordingly, there is no possibility that the bent portion interferes with other members around the protector and thus cannot be moved in the longitudinal direction, or damage to other members or the protector occurs. Further, since a slide rail portion or the like for slidingly holding the clip portion is unnecessary, the size can be easily reduced and the space can be efficiently arranged.

  According to a second aspect of the present invention, in the one described in the first aspect, the clip portion protrudes from the outer surface of the bottom wall portion of the protector body, and is formed on the bottom wall portion via the flexible portion. The bent portion is connected to the opening of the protector body while the bent portion is formed of a bent piece bent in a mountain-fold shape from the bottom wall portion of the protector body toward the opening. The protruding end portion of the bent portion is in proximity to or in contact with the lid body with a slight gap.

  According to this aspect, at the time of covering, the protruding end portion of the bent portion formed of the mountain-folded bent piece is in close proximity to or in contact with the lid body with a slight gap. Thereby, the displacement of the clip portion in the longitudinal direction of the protector body is advantageously allowed by the deformation of the bent portion, while the displacement of the clip portion in the depth direction perpendicular to the longitudinal direction of the protector body is changed to the lid of the bent portion. It is advantageously prevented by contact. Therefore, when the clip portion is fitted into the locking hole of the attached member, it is possible to prevent a problem that it becomes difficult for the clip portion to enter the protector body and to be fixed to the attached member.

  According to a third aspect of the present invention, in the one described in the second aspect, the bent portion projects from a central portion in the width direction of the bottom wall portion of the protector body, and the bent portion and the protector are provided. Between the opposing surfaces of the one side wall portion of the main body is a first electric wire insertion region, and between the opposing surfaces of the other side wall portion of the protector main body is a second electric wire insertion region. .

  According to this aspect, the electric wire can be positioned and inserted and arranged in the first electric wire insertion region and the second electric wire insertion region. Therefore, when the trunk line of the wire harness branches into a plurality of branch lines at the entrance of the protector, the wire harness can be separately routed in advance by utilizing the originally bent portion as a partition piece. Therefore, the wiring harness can be easily routed.

  According to the present invention, the clip portion is connected to the protector body or the lid body via the bending portion that can be bent and deformed in the longitudinal direction. Thereby, the dimensional error which arose between the clip parts and between the locking holes drilled in the vehicle body panel can be absorbed. And since the bending part is protrudingly provided in the protector main body, there is no possibility that a bending part may interfere with the other members around a protector. Further, since a slide rail portion or the like for slidingly holding the clip portion is not required, the size can be easily reduced and the space can be efficiently arranged.

In the present embodiment, the engagement protrusions 56 are formed in two locations on the other side wall portion 54b corresponding to the engagement frame 24 of the protector body 12, but are required to be separated in the longitudinal direction. Any number may be provided according to the above.

  As shown in FIG. 2, first, the protector body 12 having such a structure is inserted and accommodated in a state where the two wire harnesses 62a and 62b are separated. Here, the one wire harness 62 a is disposed in the first electric wire insertion region 64 formed between the opposing surfaces of the bent portion 32 and the one side wall portion 22 a of the protector body 12. On the other hand, the other wire harness 62b is disposed in a second electric wire insertion region 66 formed between the opposing surfaces of the bent portion 32 and the other side wall portion 22b of the protector body 12. When it is necessary to route the two wire harnesses 62a and 62b in the wire harness protector 10 as described above, the wire harnesses 62a and 62b are separately routed in advance by using the original bending portion 32. Therefore, the wiring harnesses 62a and 62b can be easily routed.

  Next, the upper opening 14 of the protector main body 12 in which the wire harnesses 62 a and 62 b are inserted and held in this manner is covered with the lid 16. That is, the two engagement protrusions 56 of the corresponding lid body 16 are inserted into the engagement holes 26 of the two engagement frames 24 of the protector body 12, and the engagement between the engagement frame 24 and the engagement protrusions 56.

  As shown in FIG. 1 (FIG. 4), in such a cover state, with respect to the lid body 16 attached to the upper opening 14 of the protector main body 12, the bent portion 32, that is, the protruding end portion 72 of the bent piece 34. However, they are in close proximity or in contact with each other with a slight gap. Thereby, while the bending deformation of the bending part 32 of the protector main body 12 is accept | permitted, the bending deformation of the depth direction (in FIG. 1, upper direction) orthogonal to the longitudinal direction of the bending part 32 of the protector main body 12 is bending. The protruding end 72 of the portion 32 is blocked by contact with the lid 16. Therefore, when the clip portion 18 is fitted into the locking hole 70 of the vehicle body panel 68 that is a member to be attached, it is difficult for the clip portion 18 to enter the protector body 12 and be fixed to the locking hole 70 of the vehicle body panel 68. The problem of becoming can be prevented.

  According to the wire harness protector 10 having such a structure, the clip portion 18 is connected to the protector main body 12 via the bending portion 32 that can be bent and deformed in the longitudinal direction. The connected clip portion 18 can be deformed in the longitudinal direction of the protector body 12, and a dimensional error generated between the clip portions 18, 18 and between the locking holes 70, 70 formed in the vehicle body panel 68 can be prevented. Can be absorbed.

  And since the bending part 32 is accommodated in the protector main body 12, the bending part 32 interferes with the other member around the protector 10 for wire harnesses, and it becomes difficult to move in a longitudinal direction. There is no risk of damage to the harness protector 10. Moreover, since the slide rail part etc. which slide-hold the clip part 18 are unnecessary, size reduction is easy and it can arrange | position with space efficiency.

  Next, another embodiment of the wire harness protector 10 of the present invention will be described in detail with reference to FIG. 5, but members and parts having the same structure as the above embodiment will be described with reference to FIG. The detailed description is abbreviate | omitted by attaching | subjecting the code | symbol same as a form. That is, the wire harness protector 74 is different from the above-described embodiment in that the clip portion 76 is connected to the lid body 80 instead of the protector body 78 via the bending portion 82 that can be bent and deformed in the longitudinal direction. Different embodiments are shown. Therefore, also in the wire harness protector 74 of this aspect, the clip part 76 is connected to the lid body 80 via the bending part 82 that can be bent and deformed in the longitudinal direction. Since it can be set as the structure substantially the same as the protector 10 for an object, the same effect can be acquired.

  As mentioned above, although one Embodiment of this invention has been described, this is an illustration to the last, Comprising: This invention is not limited at all by the specific description in this Embodiment. For example, in the present embodiment, the clip portion 18 is integrally formed with the protector body 12, but may be formed separately. Thereby, since it can respond to various to-be-attached members only by replacing | exchanging to a clip part, a versatility improvement and the reduction of cost can be aimed at.

  In the illustrated embodiment, the clip portions 18 and 76 are connected to the protector main body 12 or the lid body 80 via the flexible portions 32 and 82. However, depending on the structure of the attached member, The clip portions 18 and 76 may be coupled to both the lid body 80 via the flexure portions 32 and 82.
