Description

  The present invention relates to a protector that inserts and protects a wire harness, and more particularly to a protector for a wire harness that is used in a wire harness in which a corrugated tube is inserted.

  2. Description of the Related Art Conventionally, in a car or the like, a wire harness protector (hereinafter, referred to as a protector as appropriate) has been used in order to protect the wire harness from interference with other members or hold it at a predetermined location in the vehicle. The protector for a wire harness includes, for example, a protector main body through which the wire harness is inserted and a lid portion that covers the opening of the protector main body, as described in Japanese Utility Model Laid-Open No. 63-153713 (Patent Document 1). Yes.

  By the way, fixing a wire harness with respect to a protector is performed so that the wire harness inserted in the protector may not come out of a protector when tensile force is applied. For example, FIG. 5 of JP-A-8-163743 (Patent Document 2) discloses a structure in which a wire harness is taped and fixed to a tongue-shaped portion protruding from a protector body with an adhesive tape. Furthermore, in FIG. 4 of patent document 2, the protector main body and the cover body are provided with a convex portion that fits into the trough portion of the corrugated tube that is externally fixed to the wire harness, and the convex portion is provided in the trough portion of the corrugated tube. A structure is disclosed in which a wire harness is fixed to a protector by locking and fixing a main body and a lid body in a state of being fitted to the case. According to such a structure, the wire harness can be fixed to the protector without using a tape winding operation or the like by using the trough portion of the corrugated tube that is extrapolated to the wire harness.

  However, the corrugated tube extrapolated to the wire harness has a structure in which annular crests and troughs are alternately connected, and a slit for inserting the wire harness extends in the longitudinal direction. Therefore, the crests and troughs are likely to be displaced in the axial direction of the corrugated tube on both sides of the slit, and the protrusions provided on the wire harness protector may not fit well with the troughs of the corrugated tube.

  Also, in the middle part of the corrugated tube in the length direction, it is difficult to confirm whether the peaks and valleys are displaced in the axial direction on both sides of the slit, and the peaks and valleys are displaced in the axial direction. In this state, there is a tendency that a case where the protector main body and the lid body are lock-fitted by forcibly inserting the convex portion. In this case, the corrugated tube is deformed into an irregular shape, so that the wire harness is easily detached from the protector, and a desired fixing force may not be obtained.

Japanese Utility Model Publication No. 63-153713 JP-A-8-163743

  The present invention has been made in the background of the above-described circumstances, and the problem to be solved is that the corrugated tube can be easily checked for misalignment between the peaks and valleys of the corrugated tube, and the corrugated tube at the valley. An object of the present invention is to provide a wire harness protector having a novel structure capable of reliably fitting a provided convex portion.

  According to a first aspect of the present invention, there is provided a protector for a wire harness comprising a protector body extending in a bowl shape in which a wire harness with an extra corrugated tube is accommodated, and a lid that covers an upper opening of the protector body. And in one opening part of the longitudinal direction of the said protector main body, the convex part for fixation which fits into the trough part of the said corrugated tube is protrudingly provided by at least one of the inner surface of the said protector main body, and the inner surface of the said cover body. On the other hand, an intermediate lid body is provided, which is located inward of the protector body in the longitudinal direction relative to the fixing projection, and partially covers the upper opening of the protector body. An inner surface of the body and an inner surface of the protector body facing the body are fitted into a trough provided on a terminal side of the corrugated tube, and the protector body That pair of misalignment detecting protrusion protruding opposite one another at the same position in the longitudinal direction is provided, and wherein.

  In the protector for a wire harness having a structure according to the present invention, an intermediate lid that partially covers the upper opening of the protector main body is located at a position that is a middle portion in the longitudinal direction that is deeper than the longitudinal opening of the protector main body. A pair of misalignment detection projections are provided that protrude from the inner surface of the intermediate lid and the inner surface of the protector body opposite to the intermediate cover at the same position in the longitudinal direction of the protector body. Therefore, after the wire harness with the corrugated tube inserted is inserted into the protector body and before the lid is mounted, the misalignment detection convex portion is fitted into the trough on the terminal side of the corrugated tube, and the intermediate lid is fitted. Can be covered with a body. The pair of misalignment detection convex portions are fitted into the trough on the end side of the corrugated tube, but on the end side of the corrugated tube, when the crest and trough are misaligned in the axial direction It is easy to detect that a position shift has occurred due to a position shift at both corners of the slit. Therefore, it is possible to easily correct the misalignment between the peaks and valleys. In addition, since the intermediate lid partly covers the upper opening of the protector body, if the displacement in the corrugated tube slit is forcibly inserted and the misalignment detection convex portion is forcibly inserted Can easily recognize the deformed state of the corrugated tube from the outside from the region not covered with the intermediate lid, and can easily detect the displacement.

  The pair of misalignment detection convex portions are provided so as to protrude from each other at the same position in the longitudinal direction of the protector body, so that the single unit aligned from both sides sandwiching the corrugated tube in the axial direction is provided. Can be fitted into the valley of Ichino. Thus, once the intermediate lid is mounted in a state where the valley on the terminal side of the corrugated tube is aligned with the pair of misalignment detecting convex portions, the corrugated tube is attached to all the peaks and valleys. Can be temporarily held in an aligned state. Then, when the lid is attached to the protector main body, the fixing convex portion provided in the opening can be surely fitted into the valley portion of the corrugated tube in a complete state.

  Thus, according to the protector for a wire harness configured according to the present invention, the position of the peak portion and the valley portion of the corrugated tube can be obtained by using a simple configuration of the intermediate lid and the pair of misalignment detection convex portions. The presence or absence of displacement can be easily detected, and the fixing convex portion of the protector can be surely completely fitted into the valley portion of the corrugated tube. Therefore, the wire harness can be held on the protector with a desired fixing force.

  According to a second aspect of the present invention, in the first aspect, the intermediate lid is hinged to the protector body.

  In this aspect, since the relatively small intermediate lid is hinged to the protector body, the intermediate lid can be easily handled and the possibility of loss can be avoided. Further, since the intermediate lid is hinged to the protector body, the lid cannot be attached unless the intermediate lid is securely attached to the body. Therefore, forgetting to fit the intermediate lid, that is, forgetting to detect the misalignment of the corrugated tube can be reliably prevented.

  According to a third aspect of the present invention, in the above-described first or second aspect, the misalignment detection convex portion provided on the inner surface of the intermediate lid and the inner surface of the protector body. Further, the misalignment detection convex portion forms an annular shape that is fitted over the entire circumference of the valley portion of the corrugated tube in a state where the intermediate lid is closed.

  According to this aspect, with the intermediate lid closed, the valley portion of the corrugated tube extends over substantially the entire circumference by the positional deviation detecting convex portion of the intermediate lid and the positional deviation detecting convex portion of the protector body. Surrounded. This makes it possible to more reliably arrange the misalignment detection convex portions on both sides of the corrugated tube across the slit portion, and more reliably detect misalignment of the valley portions on both sides of the slit portion. And can be temporarily held in a state in which the displacement of the valleys on both sides of the slit portion is more reliably prevented.

  According to a fourth aspect of the present invention, in the one described in any one of the first to third aspects, the fixing convex portions are respectively formed on the inner surface of the protector body and the inner surface of the lid. The fixing convex portion formed on the inner surface of the protector main body and the fixing convex portion formed on the inner surface of the lid body are all in the valley portion of the corrugated tube with the lid body closed. It forms a ring shape that is fitted over the circumference.

  According to this aspect, the valley portion of the corrugated tube is sandwiched between the fixing convex portion of the protector body and the fixing convex portion of the lid body over the substantially entire circumference in a state where the lid body is closed. Thereby, a corrugated tube and by extension, a wire harness can be firmly fixed with a protector.

  According to a fifth aspect of the present invention, in the one described in any one of the first to fourth aspects, the pair of misalignment detection convex portions are in the longitudinal direction of the protector body, and the corrugated tube A plurality of pitches are provided at the same pitch as that of the valleys.

  According to this aspect, in the axial direction of the corrugated tube, by inserting a pair of misalignment detection convex portions into the plurality of troughs, the positional deviation in the axial direction of the peak and trough portions of the corrugated tube can be more accurately performed. Can be detected.

  In the present invention, an intermediate lid that partially covers the upper opening of the protector body is provided, and a misalignment detection convex portion that fits into the valley of the corrugated tube is provided on the opposing surface of the intermediate lid and the protector body. Provided. Thereby, before attaching the lid to the protector body, the intermediate lid is attached to the protector body, and the convex portion for detecting the misalignment between the intermediate lid and the protector body is fitted to the valley portion of the corrugated tube. When the valley portion of the corrugated tube is displaced in the axial direction, it can be detected that the displacement has occurred due to the displacement of the corner portions at both ends of the slit. And a corrugated tube can be temporarily held by fitting the convex part for position shift detection of a middle cover and a protector main part to the trough part of a corrugated tube. As a result, the fixing projection provided in the opening of the protector body can be securely fitted to the trough of the corrugated tube when the lid is attached, and the corrugated tube and thus the wire harness can be made stronger. Can be held.

The tip end edge protruding from the inner surface 56 has an arc shape. These fixing convex portions 32 b are formed at the same positions as the fixing convex portions 32 a of the protector body 16 in the longitudinal direction of the protector body 16 in the closed state of the lid body 18. Thus, in the closed state of the lid body 18, the fixing convex portion 32 a of the protector body 16 and the fixing convex portion 32 b of the lid body 18 face each other in the longitudinal direction of the protector body 16, and these fixing convex portions A substantially annular shape that is continuous over substantially the entire circumference is formed by 32a and the fixing convex portion 32b.

  The wire harness 12 is inserted through such a wire harness protector 10. The wire harness 12 is a conventionally known one, and is configured by bundling a plurality of electric wires 60. A corrugated tube 14 is extrapolated to the wire harness 12 of the present embodiment. As conventionally known, the corrugated tube 14 is a bellows-shaped cylindrical body in which crests 62 having a large outer diameter and troughs 64 having a small outer diameter are alternately formed. A slit 66 extending over the entire length of the corrugated tube 14 is formed at one place in the circumferential direction of the corrugated tube 14, and the corrugated tube 14 is divided in the circumferential direction by the slit 66. The corrugated tube 14 is opened from the slit 66 and the wire harness 12 is accommodated, so that the corrugated tube 14 can be easily extrapolated to the wire harness 12. Thereafter, the corrugated tube 14 is fixed to the wire harness 12 by winding a vinyl tape (not shown) around the outer surface of the corrugated tube 14 and the outer surface of the wire harness 12.

  As shown in FIG. 4A, first, the protector 10 is assembled to the wire harness 12 by inserting the wire harness 12 with the corrugated tube 14 inserted from the upper opening 24 of the protector body 16 into the protector body 16. insert. Thereby, the wire harness 12 is accommodated in the protector main body 16, and is extended outside the protector main body 16 from the openings 26a and 26b on both sides. Further, when the wire harness 12 is inserted into the protector main body 16, the terminal 68 of the corrugated tube 14 is arranged on the opening 26 a side of the protector main body 16, and a position shift is detected in each trough 64 on the terminal 68 side. The convex part 44b for fixing and the convex part 32a for fixing are respectively fitted. In addition, the opposite side of the terminal 68 of the corrugated tube 14 extends to the outside of the protector body 16 through the opening 26a.

  Next, as shown in FIG. 4 (b), the intermediate lid 38 is closed via the hinge portion 40, and the intermediate engagement piece 46 of the intermediate lid 38 becomes the intermediate engagement portion of the protector body 16. It is inserted in 50 frames. Then, the engaging claw 48 of the intermediate engaging piece 46 gets over the engaging protrusion 51 of the intermediate engaging portion 50 and is engaged, so that the intermediate lid 38 is in a closed state partially covering the upper opening 24. Retained. When the intermediate lid 38 is closed, the positional deviation detection convex portion 44a of the intermediate lid 38 is positioned at each valley portion 64 on the terminal 68 side of the corrugated tube 14, more specifically, the position of the opposing protector body 16. It fits into the trough 64 fitted with the deviation detecting convex portion 44b. As a result, the misalignment detection convex portion 44b of the protector body 16 and the misalignment detection convex portion 44a of the intermediate lid 38 are fitted into the valley portion 64 of the corrugated tube 14 over substantially the entire circumference.

  Thereafter, as shown in FIG. 4C, each engaging piece 52 of the lid 18 is inserted into the frame of the engaging portion 28 of the protector body 16. Then, the engaging claw 54 of each engaging piece 52 gets over the engaging protrusion 30 of the engaging portion 28 and is engaged, whereby the lid 18 is assembled to the protector body 16 and the upper opening of the protector body 16 is opened. The part 24 is covered with the lid 18 over the entire length. Thereby, the fixing convex part 32b of the lid 18 is fitted to the trough part 64 of the corrugated tube 14, more specifically, the trough part 64 to which the fixing convex part 32a of the opposing protector body 16 is fitted. Is done. As a result, the fixing convex portion 32a of the protector body 16 and the fixing convex portion 32b of the lid body 18 are fitted into the valley portion 64 of the corrugated tube 14 over substantially the entire circumference, and these fixing convex portions 32a. , 32b, the corrugated tube 14 is prevented from coming out of the protector 10. In this way, the protector 10 is assembled to the wire harness 12.

  In the wire harness protector 10 having the structure according to the present embodiment, before the cover 18 is assembled to the protector body 16, the intermediate cover 38 is closed to detect the misalignment detection convex portion 44a of the intermediate cover 18, and the protector. The misalignment detection convex portion 44 b of the main body 16 is fitted into the valley portion 64 of the corrugated tube 14. Thereby, when the trough part 64 and the crest part 62 of the corrugated tube 14 are misaligned in the axial direction, it is possible to easily detect the misalignment of both corners of the slit 66. Further, since the intermediate lid 38 partially covers the upper opening 24 of the protector main body 16, when the corrugated tube 14 is displaced, the corrugated tube starts from the portion not covered with the intermediate lid 38. 14 deviations can be easily detected. In particular, in the present embodiment, a plurality of misalignment detection convex portions 44 a and 44 b are provided in the axial direction at the same pitch as the valley portion 64 of the corrugated tube 14. Thus, the positional deviation in the axial direction of the portion 64 can be detected with higher accuracy.

  Further, the misalignment detection convex portion 44 a of the intermediate lid 38 and the misalignment detection convex portion 44 b of the protector body 16 are provided at the same position in the longitudinal direction of the protector body 16. Therefore, the state where all the peak portions 62 and the valley portions 64 are aligned with each other by fitting both the misalignment detection convex portions 44a and 44b to the same valley portion 64 of the corrugated tube 14. Can be temporarily held. As a result, when attaching the lid 18, the fixing projections 32 a and 32 b provided on the protector body 16 and the lid 18 are fitted into the valley 64 of the corrugated tube 14 in a complete state, and the corrugated The tube 14 and thus the wire harness 12 can be firmly held. In particular, in the present embodiment, since the intermediate lid 38 is connected to the protector main body 16 by the hinge portion 40, the positional deviation detecting convex portion 44a of the intermediate lid 38 and the positional deviation detecting convex of the protector main body 16 are provided. The portion 44b can be positioned stably and accurately in the longitudinal direction of the protector body 16. Further, since the misalignment detecting convex portions 44a and 44b are provided in the longitudinal direction of the protector body 16 at positions close to the fixing convex portion 32a, the fixing convex portion is provided at the terminal 68 of the corrugated tube 14. The length dimension for extending from 32a to the positional deviation detection convex portions 44a and 44b can be reduced. As a result, the length dimension of the corrugated tube 14 can be suppressed to the minimum required in the wiring path of the wire harness 12, and the manufacturing cost can be reduced. The misalignment detection convex portions 44a and 44b are engaged with the fixing convex portions 32a and 32b by fitting the valley portions 64 of the corrugated tube 14 in the same manner as the fixing convex portions 32a and 32b. The corrugated tube 14 and the wire harness 12 can be fixed more firmly.

  In addition, since the intermediate lid 38 is connected to the protector main body 16, the possibility of losing the intermediate lid 38 can also be avoided. In addition, if the intermediate lid 38 is not securely attached to the protector body 16, the lid 18 cannot be attached, so that the intermediate lid 38 is forgotten to be fitted, that is, the misalignment of the corrugated tube 14 is detected. Forgetting can be reliably prevented.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited by the specific description. For example, the specific shape of the protector for the wire harness can be appropriately set in consideration of the installation space of the protector, the wiring mode of the wire harness, and the like, and may be a bent shape.

  In addition, the intermediate lid may be formed separately from the protector body. In addition, the lid body is not limited to the lid body formed separately from the protector body, and may be connected to the protector body by a hinge portion, for example.

  Furthermore, the number of the convex portions for fixing and the convex portions for detecting misalignment can be set to an arbitrary number in consideration of the required holding force of the corrugated tube and the accuracy of detecting the misalignment of the corrugated tube. . Moreover, the fixing convex portion may be formed only on the inner surface of the protector body or only on the inner surface of the lid. Further, the fixing convex portion and the misalignment detecting convex portion are not necessarily provided close to each other in the longitudinal direction of the protector body. For example, the fixing convex portion is provided at one end of the protector main body. On the other hand, a misalignment detection convex portion may be provided at the other end of the protector body or at the center in the longitudinal direction. The fixing convex portion and the positional deviation detecting convex portion are not necessarily limited to the ring shape surrounding the corrugated tube over the entire circumference, but are partially fitted on the circumference of the valley portion of the corrugated tube. For example, in the above-described embodiment, the fixing convex portion 32a and the positional deviation detecting convex portion 44b on the protector body 16 side may protrude only from the inner surface 32c of the bottom wall 20.
