Description

  The present invention relates to a tubular exterior member that accommodates and protects one or a plurality of conductive paths, and a wire harness that includes the exterior member.

  For example, taking a high-voltage wire harness as an example, Patent Document 1 below discloses a wire harness that electrically connects high-voltage devices mounted on a hybrid vehicle or an electric vehicle. The wire harness of Patent Document 1 is by the applicant of the present application, and includes one or a plurality of conductive paths and a tubular-shaped exterior member that is inserted and protected through the one or a plurality of conductive paths. The The wire harness of patent document 1 is a long thing routed under the vehicle floor.

  In the wire harness of Patent Document 1, the conductive path is fixed by tape winding at the position of the terminal portion of the exterior member. The conductive path is also held by the protector at the front and rear positions under the vehicle floor while being inserted through the exterior member. Regardless of whether it is an exterior member or a protector, the conductive path is fixed in such a manner that one end side and the other end side are separated from each other, and the intermediate portion is accommodated with a gap between the exterior member and the conductive path. In the housed state, for example, when vibration during traveling is transmitted to the conductive path, the conductive path may swing and hit the inner surface of the exterior member. That is, there is a possibility that the conductive path side may be scraped.

  Accordingly, it is conceivable to eliminate the above-mentioned concern by adopting the wire harness disclosed in Patent Document 2 below. The wire harness of Patent Document 2 is formed in a shape in which a corrugated tube constituting the wire harness has a belly part (the exterior member is formed in a shape having a slit). Further, the corrugated tube is also formed in a shape in which an elastic lip portion is continued to the bellows portion so that the conductive path inserted through the bellows portion does not shake. The corrugated tube is wound with a tape so as to cover the part of the belly after the conductive path is inserted.

  However, the wire harness of Patent Document 2 has the following problems. That is, for example, if there is a stepping stone during running, the tape winding breaks, and from there, for example, water enters the corrugated tube due to flying water, which eventually causes a problem. In addition, since an exterior member having a stomach part is employed, a necessary and sufficient rigidity cannot be ensured.

In FIG. 2, the harness body 19 includes a conductive path 21 and an exterior member 22 of the present invention for accommodating and protecting the conductive path 21. Note that the number of conductive paths 21 is one in FIG. 2, but this is an example. That is, it may be a plurality. Moreover, regarding the exterior member 22, a member that accommodates and protects the high-voltage wire harness 9 together may be adopted. First, the conductive path 21 in the harness body 19 will be described, and then the exterior member 22 of the present invention will be described.

<About the conductive path 21>
2 and 4, the conductive path 21 includes a conductive conductor 23 and an insulating insulator 24 that covers the conductor 23. The conductor 23 is formed in a circular cross section by copper, copper alloy, aluminum, or aluminum alloy. The conductor 23 has a conductor structure in which strands are twisted together or a rod-shaped conductor structure having a rectangular or circular (round) cross section (for example, a conductor structure having a flat single core or a round single core. The wire itself may be a rod shape). An insulator 24 made of an insulating resin material is extruded on the outer surface of the conductor 23 as described above.

  The insulator 24 is extruded on the outer peripheral surface of the conductor 23 using a thermoplastic resin material. The insulator 24 is formed as a covering having a circular cross section. The insulator 24 is formed with a predetermined thickness. As the thermoplastic resin, various known types can be used, and are appropriately selected from polymer materials such as polyvinyl chloride resin, polyethylene resin, and polypropylene resin. Reference numeral 25 indicates the outer peripheral surface of the conductive path 21 (here, corresponding to the outer peripheral surface of the insulator 24). This outer peripheral surface 25 becomes a surface which contacts the below-mentioned convex part 30 which is the characteristic part of this invention.

<About the exterior member 22 of the present invention>
In FIG. 2, the exterior member 22 is formed into a single straight tube shape by resin molding (it is straight before use. In addition, it is not limited to resin but may be made of metal. And). Moreover, the exterior member 22 is formed in the shape without a stomach split. In other words, it is formed in a shape without a slit (formed in a shape that is not a split tube). Further, the exterior member 22 is formed in a circular cross section (in this embodiment, it is a perfect circle, but it is only an example, and may be an elliptical cross section, an ellipse, a rectangle, etc.). .

  Such an exterior member 22 has a flexible tube portion 26 having flexibility, and a straight tube portion 27 as a portion for routing the conductive path 21 straight. A plurality of flexible tube portions 26 and straight tube portions 27 are formed. These are alternately formed. It should be noted that the form of the present embodiment having such a configuration and arrangement is an example (it is only necessary to be able to provide a characteristic portion of the present invention to be described later, and for example, a known corrugated tube can also be applied. Suppose).

  In FIG. 4, one end portion 28 of the exterior member 22 is formed as an insertion end of the conductive path 21. That is, the conductive path 21 is inserted from one end portion 28. On the other hand, the other end portion 29 of the exterior member 22 is formed as a lead-out end of the conductive path 21. That is, the conductive path 21 that has passed through the interior of the exterior member 22 is led out from the other end portion 29. In the present embodiment, the other end portion 29 is formed to be narrowed as shown in the figure. This is because it is better to restrict the insertion direction of the conductive path 21 because it is a characteristic part of the present invention described later. If the shape of the other end 29 is constricted, it becomes difficult to insert the conductive path 21 from this side, and as a result, the operator can easily know that the insertion direction is wrong. . In addition to the narrowed shape as described above, it is also effective to restrict insertion using a jig, for example. Of course, if the shape of the one end portion 28 and the other end portion 29 is different, it becomes possible to discriminate humanly and mechanically.

<About the flexible tube portion 26>
In FIG. 2, the flexible tube portion 26 is arranged in accordance with the vehicle mounting shape (the shape of the wire harness wiring destination, the shape to be fixed). Moreover, the flexible tube part 26 is also formed in the length matched with the vehicle attachment shape. The length of the flexible tube portion 26 is not constant and is formed to a required length according to the vehicle mounting shape. Such a flexible tube portion 26 is formed in a portion that can be bent at a desired angle when the wire harness 15 is packed, transported, or routed to the vehicle. That is, the flexible tube portion 26 is formed in a portion that can be bent to have a bent shape and can be naturally returned to the original state (the state at the time of resin molding) as illustrated. The

  In the present embodiment, the flexible tube portion 26 is formed in a bellows tube shape (the shape is not particularly limited as long as it has flexibility). Specifically, the bellows concave portion and the bellows convex portion in the circumferential direction are formed, and the bellows concave portion and the bellows convex portion are formed alternately and continuously in the tube axis direction.

<About the straight pipe section 27>
In FIG. 2, the straight tube portion 27 is formed as a portion having no flexibility like the flexible tube portion 26. The straight pipe portion 27 is also formed as a portion that does not bend during packing, transportation, or route routing (the portion that does not bend means a portion that does not actively have flexibility). . The straight pipe portion 27 in the figure is formed in a long straight pipe shape.

  The straight tube portion 27 is formed in a rigid portion as compared with the flexible tube portion 26. The straight pipe portion 27 is formed in a position and a length according to the vehicle mounting shape. In this embodiment, the straight pipe portion 27 is formed as a portion disposed at least under the vehicle floor 11 (see FIG. 1). A plurality of convex portions 30, which is a characteristic portion of the present invention, are integrally formed on a part or the whole of the straight pipe portion 27.

The taper portion 34 is formed as a portion arranged at a continuous position of the R portion 32 and the oblique side portion 33 (as shown in FIG. 5, formed as a portion arranged in a C-shaped taper). The tapered portion 34 is formed as a portion for smoothing the insertion operation of the conductive path 21. The formation of the tapered portion 34 is arbitrary.

  The conductive path guiding inclined surface portion 35 is formed as a portion that is inclined in the tube axis direction from the R portion 32 and continues to the tube inner surface 31. In addition, since the conductive path guiding inclined surface portion 35 is inclined as described above, it is also formed as a portion for smoothly inserting the conductive path 21. On the other hand, the connecting slope part 36 is formed as a part connecting the oblique side part 33, the taper part 34, the side part of the conductive path guiding slope part 35, and the pipe inner surface 31.

  The wall portion 37 is formed as a wall-shaped portion substantially orthogonal to the tube axis direction. For example, even when an external force (for example, an external force from the direction of arrow A) is applied to the wall portion 37 from a direction perpendicular to the exterior member 22, the exterior member 22 is not easily bent or broken. It is formed as such a part. That is, the wall portion 37 is formed as a portion that can prevent a decrease in rigidity (not limited to a wall, but may be a rib shape, for example). In other words, it is formed as a portion that secures necessary and sufficient rigidity. In this embodiment, the wall portion 37 is arranged and formed in accordance with the position of the R portion 32 (this is an example, and the arrangement is not particularly limited as long as rigidity can be ensured).
