Description

  The present invention relates to a protector and a wire harness that house a harness body in which an outside of an electric wire group is covered with a bellows-like corrugated tube.

  Conventionally, in order to protect the harness body in which the outer side of the electric wire group is covered with a bellows-like corrugated tube, a protector body having a substantially U-shaped cross section with one surface opened, and a cover body covering the open surface of the protector body, A protector provided is known (see, for example, Patent Documents 1 and 2).

  The protector holds the corrugated tube by covering the protector body with a cover body in a state where the corrugated tube is housed in the protector body.

  That is, ribs that engage with the bellows-like annular recesses are formed on the inner surfaces of the end portions of the protector body and the cover body in order to prevent displacement along the axial direction of the corrugated tube.

  On the other hand, the wiring route of the harness body is not necessarily linear, and at least a part of the housing direction reaching the end of the protector body is bent obliquely, and the entire protector is configured in a two-dimensional or three-dimensional solid shape. May have.

  However, in such a conventional protector, for example, in the protector of Patent Document 1 described above, the protector body and the cover body have an axis perpendicular to the annular recess direction of the corrugated tube in the vicinity of the end of the protector body. It is formed integrally through a thin-walled hinge.

  For this reason, when the vicinity of the end of the protector is bent in a two-dimensional or three-dimensional direction, a thin-walled hinge cannot be provided, and the thin-walled hinge must be disposed near the center of the protector body.

  Thus, when the thin hinge is arranged near the center of the protector body, the thin hinge and the end holding the corrugated tube are arranged apart from each other, and the end is shifted in the two-dimensional or three-dimensional direction. Therefore, it is difficult to engage the rib of the cover body with the annular recess of the corrugated tube, and there is a problem that the rib of the cover body crushes the annular protrusion of the corrugated tube and engages the annular recess.

  Further, as in Patent Document 2 shown in FIG. 3, the protector main body 1 and the cover body 2 are configured separately, and the end cover 4 is separated from the end of the cover body 2 via the shaft 3. , The shaft 3 and the rib 4a formed on the end cover 4 can be brought close to each other. However, the shaft 3 is separated from the corrugated tube 5 radially outward. That is, the axis line of the shaft 3 and the groove bottom of the annular recess 5a of the corrugated tube 5 are separated by a distance W in the illustrated height direction. In addition, since the axis of the shaft 3 and the annular recess 5a of the corrugated tube 5 are fixed in parallel, the annular protrusion of the corrugated tube 5 is formed at the tip of the rib 4a when the end cover 4 is rotated. The problem of crushing the part 5b still remained.

  The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a protector and a wire harness that can close one surface without crushing a corrugated tube.

  The protector according to the present invention is a protector for housing a harness body in which the outside of an electric wire group is covered with a bellows-like corrugated tube in order to achieve the above-described object, wherein one surface is opened and at least in the housing direction reaching one end. A protector body that is partially bent obliquely, a main cover that closes an open surface excluding the one end of the protector body, and the protector body and the main cover that are connected in an unfolded state. A main hinge that bends so that the open surface excluding the one end can be closed by the main cover, an end cover that closes an open surface corresponding to the one end of the protector body, the main cover, and the An end portion which is bent or deformed so as to be able to close the open surface corresponding to the one end portion of the protector body by connecting the end cover with the end cover. A hinge, a body-side rib provided on the inner surface corresponding to the one end of the protector body and engageable with the corrugated tube, and an end cover provided on the inner surface of the end cover. And a cover-side rib that can be engaged with the corrugated tube when the open surface corresponding to the portion is closed, and the end hinge is formed by bending the main hinge and the one end. When the open surface except for is closed by the main cover, the open surface corresponding to the one end is offset with respect to the main cover so that it is in a retracted position that is not closed by the end cover.

  With this configuration, the protector according to the present invention can easily align the rib of the end cover with the annular recess of the corrugated tube by the end hinge, and the end cover can be attached to one end of the protector body. When closing the corresponding open face, it can be closed without crushing the corrugated tube.

  In addition to the protector, the wire harness according to the present invention comprises a harness body in which the outside of the electric wire group is covered with a bellows-like corrugated tube, the harness body is accommodated in the protector, the main cover and the end portion The entire cover is closed with a cover for the body, and the main body side rib and the cover side rib are engaged with the corrugated tube so that the corrugated tube is connected to one end of the protector main body and the end cover. It is a held configuration.

  With this configuration, according to the wire harness according to the present invention, it is possible to provide a wire harness in which the corrugated tube is not crushed by the ribs of the end cover when the one surface of the protector body is closed by the main cover.

  Next, an embodiment according to the present invention will be described with reference to the drawings.

  First, the configuration of the protector will be described. The protector 10 shown as this Embodiment is applied to a vehicle harness main body or the like. As shown in FIGS. 1 and 2, the protector 10 includes a protector main body 11 having a substantially U-shaped cross section with one open surface, and a main cover 12 that closes an open surface 11 b of the central portion 11 </ b> B excluding one end 11 </ b> A of the protector main body 11. A main hinge 13 that connects the protector main body 11 and the main cover 12 in an unfolded state, an end cover 14 that closes the open surface 11a corresponding to the one end 11A of the protector main body 11, and the main cover 12 and end cover This is a resin molded product that integrally includes an end hinge 15 that is connected to the cover 14 in a deployed state and is bent so as to close the open surface 11a corresponding to the one end 11A of the protector body 11. In addition, regarding the resin material, it is arbitrary according to the position, environment, etc. installed in a vehicle body.

  The protector main body 11 is bent at a midway portion toward the one end 11A along a route for routing a harness main body (not shown) according to the installation location of the vehicle body. For this reason, the main hinge 13 is disposed closer to the center of the protector body 11. The protector body 11 is integrally formed with a plurality of female engaging portions 11c on its side surface. On the inner wall surface of one end 11 </ b> A of the protector body 11, a body-side rib 11 d that engages with an annular recess 16 a formed in a bellows-like corrugated tube 16 that constitutes the harness body is formed.

  The main cover 12 is bent in accordance with the bent shape of the protector body 11. The main cover 12 is integrally provided with a lance-shaped male engagement claw portion 12a that engages with the engagement portion 11a so as to maintain the state when the open surface 11b of the central portion 11B of the protector body 11 is closed. Is formed.

  The main hinge 13 connects the protector main body 11 and the main cover 12 in an unfolded state, and bends so that the main cover 12 can close the open surface 11b of the central portion 11B excluding the one end 11A of the protector main body 11.

  The end cover 14 has a lance-like male engagement claw 14a that engages with the engagement portion 11a so as to maintain the state when the open surface 11a of the one end 11A of the protector body 11 is closed. Are integrally formed. On the inner wall surface of the end cover 14, a cover-side rib 14 b that engages with an annular recess 16 a formed in the corrugated tube 16 is formed.

  The end hinge 15 can rotate the position of the end cover 14 with respect to the main cover 12 by elastic deformation. Specifically, the end hinge 15 is bent between the main cover 12 and the end cover 14 so as to protrude outward in the radial direction, that is, on the side opposite to the protector body 11. . At this time, as shown in FIG. 1 (C), the end hinge 15 is bent at the one end 11A when the main cover 13 is bent and the open surface 11b of the central portion 11B except the one end 11A is closed by the main cover 12. Is offset with respect to the main cover 12 so that the open surface 11a corresponding to is in a retracted position that is not closed by the end cover 14. Therefore, the end hinge 15 can be elastically deformed, and at the same time has a shape retaining property capable of maintaining the above-described offset state by setting the wall thickness or the like.

  Next, the operation of the protector according to this embodiment will be described.

  In the above configuration, the protector 10 can close the open surface 11b of the central portion 11B of the protector body 11 with the main cover 12, as shown in FIGS. At this time, the main cover 12 rotates with the main hinge 13 as a rotation fulcrum and closes the open surface 11b of the central portion 11B of the protector body 11 simply by engaging the engaging claw portion 12a with the engaging portion 11c. Can do.

  Further, the end cover 14 is rotated independently of the main cover 12 using the end hinge 15 as a rotation fulcrum, and the engagement claw portion 14a is engaged with the engagement portion 11c. 11 can close the open surface 11a of the one end 11A.

  Here, when the protector body 11 is covered only with the main cover 12, the end cover 14 is not covered with the corrugated tube 16 accommodated in the protector body 11 by the offset function of the end hinge 15. It can be in a state where it is in contact or simply in contact.

  The end cover 14 is aligned so that the cover-side rib 14b engages with the annular recess 16a of the corrugated tube 16, as shown in FIG. However, the open surface 11a can be closed by engaging the engaging claw portion 12a with the engaging portion 11c.

  As a result, the end cover 14 uses the end hinge 15 having an axis parallel to the annular recess 16a of the corrugated tube 16 and utilizes expansion and contraction due to elastic deformation of the end hinge 15. It is possible to absorb misalignment during rotation. Therefore, when the end cover 14 covers the one end portion 11 </ b> A of the protector main body 11, it is possible to prevent the annular convex portion 16 b of the corrugated tube 16 from being crushed by the load.

  Further, the end cover 14 can be provided only at the one end 11A of the protector body 11, and the axial direction of the end hinge 15 can be parallel to the cover-side rib 14b. The design of the end shape of the protector 10 is not hindered.

  Further, the end hinge 15 can be inclined so that when the protector body 11 is covered with the end cover 14, the bent portion, that is, the folded vertex portion is located above the main cover 12. . Thereby, the load by bending and inclination of the end hinge 15 can be used as a pressing member of the main cover 12, and the floating of the central portion 11B near the one end portion 11A of the main cover 12 can be suppressed. For this reason, it is possible to omit providing the engaging means in the vicinity of the one end portion 11A of the main cover 12.

  As described above, the protector 10 according to the present embodiment has a configuration in which the end cover 14 is integrally formed with the main cover 12 by the elastically deformable end hinge 15. The rotation trajectory of the end cover 14 is not affected by expansion and contraction due to elastic deformation. Thereby, it is possible to provide a margin for the rotation of the end cover 14, and when the end cover 14 closes the open surface 11 a of the one end portion 11 </ b> A of the protector body 11, The possibility of being crushed can be suppressed.

  Thus, the protector 1 according to the present embodiment easily aligns the cover-side rib 14b of the end cover 14 and the annular recess 16a of the corrugated tube 16 by elastic deformation of the end hinge 15. When the open surface 11a of the one end portion 11A of the protector body 11 is closed by the end cover 14, the annular convex portion 16b of the corrugated tube 16 can be closed without being crushed.

  Further, in the protector 10 of the present embodiment, the end hinge 15 has an axis parallel to the annular recess 16a of the corrugated tube 16, so that the open surface 11a of the one end 11A of the protector body 11 is the end. When the end cover 15 is closed, the end hinge 15 expands and contracts so that the cover side rib 14b of the end cover 14 can be easily aligned with the annular recess 16a of the corrugate tube 16. The open surface 11a of the one end portion 11A of the protector body 11 can be closed by the end cover 14 without crushing the annular convex portion 16b.

  Further, in the protector 10 of the present embodiment, when the end hinge 15 is not elastically deformed, the end cover 14 is offset with respect to the main cover 12. When the open surface 11b of the central portion 11B is closed, the cover-side rib 14b of the end cover 14 can be prevented from contacting the corrugated tube 16. Further, in a state where the open surface 11a of the one end portion 11A of the protector body 11 is closed with the end cover 14, the end hinge 15 can be inclined to the central portion 11B near the one end portion 11A of the main cover 12, The end hinge 15 can be provided with a function of suppressing the floating of the central portion 11B of the main cover 12.

  As described above, the protector according to the present invention has an effect that the corrugated tube can be covered without being crushed, and is useful for all protectors that protect the harness body covered with the corrugated tube.
