Description

  The present invention relates to a wire harness guide member that regulates the bending direction of a wire harness.

  As is well known, for example, an automobile is provided with a slide member that slides and displaces relative to the vehicle body, such as a seat and a slide door. These slide members may be connected to the vehicle body by a wire harness in order to supply electric power from the vehicle body side or transmit an electric signal to or from the vehicle body side.

  By the way, since the wire harness connected to the slide member moves following the slide member, the wire harness may interfere with other members provided around the slide member such as a guide rail. Therefore, in order to prevent the wire harness from interfering with other members, the bending form is limited by inserting the wire harness through a corrugated tube having a bellows tube shape.

  However, since the corrugated tube can be bent in any direction, it is insufficient to restrict the bending direction of the wire harness to a specific direction. Therefore, when connected to a member whose movement direction is specified, such as a slide member, there is a risk of bending out of the movement direction, and it is still insufficient to prevent interference with other members. there were.

  Japanese Patent Laying-Open No. 2006-166492 (Patent Document 1) discloses a wire harness in which a plurality of pieces in which a pair of side plate portions sandwiching a wire harness are protruded from both ends of the bottom plate portion are connected by hinge portions in the bottom plate portion. Guide members have been proposed. If such a guide member is used, since the bending direction of the guide member is limited to the bending direction of the hinge portion, the bending direction of the wire harness can be limited to a specific direction.

  However, the wire harness guide member described in Patent Document 1 has an extension formed by extending the side plate portion to the opposite side of the bottom plate portion, and the extension portion makes contact with the extension portion of the adjacent piece. The bending of the direction is suppressed. Therefore, when trying to fix the wire harness to the guide member with tape, the tape is attached only to these extensions, and it is not possible to secure a sufficient tape attachment area with the bottom plate part. There was a risk that sufficient fixing force could not be obtained. In addition, when the wire harness diameter is small and does not protrude from the side plate portion, the wire harness may be close to the loosely inserted state on the tape wound around the pair of side wall portions and may not be fixed to the guide member. there were. In addition, although FIG. 8 of Patent Document 1 proposes a wire harness guide member provided with a lid-like harness holding plate that prevents the wire harness from coming out for each piece, in such a structure, In addition to causing an increase in the forming material, all the harness holding plates have to be closed in order to fix the wire harness, and there is a problem that it takes time and effort.

JP 2006-166492 A

  The present invention has been made in the background of the above-mentioned circumstances, and the solution to the problem is that a wire harness having a wider diameter can be stably fixed with a tape, and the wire harness can be fixed. An object of the present invention is to provide a wire harness guide member having a novel structure that can be easily performed.

  A first aspect of the present invention is a wire harness guide member that regulates a bending direction of a wire harness, the bottom plate extending with a certain rectangular cross-sectional shape and capable of being curved and deformed in the extending direction, and the bottom plate The plurality of guide protrusions projecting from both side edge portions on one surface in the plate thickness direction of the part are integrally formed of synthetic resin, and the plurality of guide protrusions are extended from the bottom plate part. A tape guide gap is formed between the pair of guide protrusions adjacent to each other in the extending direction of the bottom plate portion so that the tape for fixing the wire harness can be inserted by being arranged at an interval in the extending direction. On the other hand, a flat tape adhering surface is formed over the entire bottom plate portion on the other surface in the plate thickness direction opposite to the surface on which the guide protrusion protrudes in the bottom plate portion. The features To.

  According to the wire harness guide member structured according to the present invention, since the bottom plate portion that can be bent only in the extending direction is provided, the wire harness is fixed to the bottom plate portion with a tape, so that the wire harness is bent in the bending direction. Can be limited only to the extending direction in which the bottom plate portion can be bent. Further, since the guide projections are provided on both side edges of the bottom plate portion, the wire harness can be sandwiched between the guide projections and stably fixed on the bottom plate portion. As a result, when the wire harness is connected to a member that moves only in the front-rear direction, such as a slide member, the wire harness can be guided without deviating from the moving direction of the member, and the wire harness can be guided to other peripheral members. Can be protected from interference.

  And the flat tape sticking surface is formed over the whole bottom plate part in the plate | board thickness direction other surface on the opposite side to the surface where the guide protrusion protruded in the bottom plate part. Thereby, it is possible to sufficiently secure a tape sticking area between the bottom plate portion and the wire harness can be stably fixed to the bottom plate portion.

  Further, a tape guide gap is formed between the plurality of guide protrusions, and the tape for fixing the wire harness can be directly attached to the wire harness from the tape attaching surface of the bottom plate portion through the tape guide gap. I can do it. Thereby, the tape winding operation can be easily performed. Further, by winding the tape with the tape guide gap as a mark, variations in winding of the tape by the operator can be suppressed. Further, unlike the guide member described in Patent Document 1, since the tape is not wrapped around the side plate portion and can be directly attached to the wire harness from the bottom plate portion, the bottom plate portion regardless of the diameter dimension of the wire harness. The tape can be securely attached to both the wire harness and the wire harness, and the wire harness can be stably fixed to the bottom plate portion.

  According to a second aspect of the present invention, in the one described in the first aspect, as the guide projection protrudes from one surface in the plate thickness direction of the bottom plate portion, the bottom plate portion extends in the extending direction. It is made into the taper board shape which a width dimension becomes small gradually.

  According to this aspect, since the guide protrusion has a plate shape, the wire harness can be stably held on the bottom plate portion. And since the guide protrusion is tapered, the size of the tape guide gap between adjacent guide protrusions can be increased on the protruding tip side of the guide protrusion, and the tape to the tape guide gap Can be easily inserted.

  A third aspect of the present invention is the one described in the first or second aspect, wherein the plurality of guide protrusions are provided at regular intervals in the extending direction of the bottom plate portion. is there.

  According to this aspect, the tape guide gap formed between the guide protrusions is formed at regular intervals in the extending direction of the bottom plate portion. Thus, the tape can be wound at substantially equal intervals in the extending direction of the guide member with the tape guide gap as a mark. As a result, the wire harness can be fixed with a better balance in the extending direction of the guide member.

  According to a fourth aspect of the present invention, in the one described in any one of the first to third aspects, the plurality of guide projections are extended in the extending direction of the bottom plate portion, and both side edges of the bottom plate portion. Are provided alternately on each side.

  According to this aspect, the plurality of guide protrusions are provided in a staggered manner in the extending direction of the bottom plate portion at both side edges of the bottom plate portion. As a result, the number of guide protrusions can be reduced and the formation material can be reduced. Further, the tape can be easily wound obliquely in the extending direction of the bottom plate portion.

  In the wire harness guide member structured according to the present invention, a plurality of guide projections are provided on both side edges of the bendable bottom plate portion at intervals in the extending direction of the bottom plate portion, and between the guide projections. A tape guide gap was formed. Thereby, when tape-fixing a wire harness to a guide member, a tape can be penetrated to a tape guide gap | interval, and a tape can be directly affixed on a wire harness from a baseplate part. As a result, the tape can be easily wound and the wire harness can be stably fixed to the bottom plate portion with the tape regardless of the diameter of the wire harness. Moreover, the surface on the opposite side to the guide protrusion in the bottom plate portion was a flat tape adhering surface over the entire surface. Thereby, the adhesion area of a tape and a baseplate part is fully ensured, and the adhering force of a tape can be ensured stably. As a result, the wire harness can be stably fixed to the guide member.

The perspective view which shows the fixed state of the wire harness to the guide member for wire harnesses shown in FIG. IV-IV sectional drawing of FIG. Explanatory drawing for demonstrating the fixed state to the vehicle of the wire harness fixed to the guide member for wire harnesses shown in FIG. The top view which shows the fixed state of the wire harness to the guide member for wire harnesses as 2nd embodiment of this invention.

  Embodiments of the present invention will be described below with reference to the drawings.

  First, FIG. 1 shows a wire harness guide member (hereinafter referred to as a guide member) 10 as a first embodiment of the present invention. The guide member 10 is an integrally molded product made of synthetic resin in which a plurality of guide protrusions 14 are formed on both side edges of a bottom plate portion 12 having a thin longitudinal plate shape.

  The bottom plate portion 12 has a thin plate shape extending with a constant longitudinal rectangular cross section, and can be bent in the extending direction. A plurality of guide protrusions 14 are formed on a surface 16 that is one surface in the thickness direction of the bottom plate portion 12. On the other hand, a tape adhering surface 18 which is a flat surface over the entire bottom plate portion 12 is formed on the back surface which is the other surface in the thickness direction of the bottom plate portion 12. The bottom plate portion 12 is formed to be thin enough to be bent by member elasticity, and the thickness dimension: t is preferably set to 1.0 mm or less, more preferably about 0.5 mm.

  A plurality of guide protrusions 14 are formed on the surface 16 of the bottom plate portion 12. The guide protrusions 14 are formed so as to protrude perpendicularly from the surface 16 at both side edges 20 a and 20 b of the surface 16. As shown in FIG. 2, these guide protrusions 14 are arranged at a constant interval d in the extending direction of the bottom plate portion 12 (left and right direction in FIG. 2). The guide protrusions 14 have the same shape as each other, and have a plate shape having a predetermined width dimension in the extending direction of the bottom plate portion 12. In the present embodiment, the guide protrusion 14 has a substantially isosceles trapezoidal tapered shape in which the width dimension in the extending direction of the bottom plate portion 12 gradually decreases as it protrudes from the surface 16. In addition, the protrusion dimension: h from the surface 16 of the guide protrusion 14 is preferably a diameter dimension of a later-described wire harness 24 accommodated in the guide member 10 in order to ensure a protective effect of the later-described wire harness 24. It is smaller than φ (see FIG. 4), and more preferably, it is set to a diameter dimension: 1/2 or more of φ. In the present embodiment, the guide protrusion 14 on one side edge 20 a of the bottom plate 12 and the guide protrusion 14 on the other side edge 20 b are opposed to each other in the width direction of the bottom plate 12. The distance between the opposing surfaces of the pair of guide protrusions 14 and 14: w (see FIG. 4) is preferably larger than the diameter dimension φ of the wire harness 24 described later.

Further, the guide protrusions 14 in the present embodiment are formed at equal intervals d in each of the side edge portions 20a and 20b of the bottom plate portion 12. Thereby, in each of the side edge portions 20a and 20b, a tape guide gap 22 is formed between the guide projections 14 and 14 adjacent in the extending direction of the bottom plate portion 12 (left and right direction in FIG. 2). . In the present embodiment, since the guide protrusion 14 is tapered in the protruding direction from the surface 16, the tape guide gap 22 has a width dimension from the surface 16 toward the leading end side in the protruding direction of the guide protrusion 14. : Ws is gradually increased. The minimum width dimension: ws _min of the tape guide gap 22 is preferably larger than the width dimension of the tape 26 to be described later, and the guide projection 14 is not formed in the tape guide gap 22, and the bottom plate Since the influence on the amount of bending deformation of the portion 12 is large, it is preferably set within a range of 15 mm to 30 mm, more preferably 20 mm to 25 mm so as to ensure the amount of bending deformation of the bottom plate portion 12.

  As shown in FIG. 3, the wire harness 24 is fixed to the guide member 10 having such a structure. The wire harness 24 may be one in which a corrugated tube is extrapolated to a plurality of electric wires, or may be one in which a plurality of electric wires are bundled without a corrugated tube. The wire harness 24 is inserted between the guide protrusions 14, 14 formed on both side edges 20 a, 20 b of the guide member 10, and is placed on the surface 16 of the bottom plate 12, and is connected to the bottom plate 12. The tape 26 is wound around the wire harness 24 in the extending direction so as to be fixed to the guide member 10.

  As shown in FIG. 4, the tape 26 is inserted into the tape guide gap 22 formed between the guide projections 14 and 14 adjacent to each other in the extending direction of the bottom plate portion 12 of the guide member 10, and the bottom plate portion 12 and the wire. It is wound around the harness 24. Thereby, while tape 26 is stuck over the full length of the width direction (left-right direction in Drawing 4) of bottom plate part 12 to tape sticking surface 18 which is the back of bottom plate part 12, bottom plate part A portion extending from 12 is directly attached to the wire harness 24 through the tape guide gap 22.

  For example, as shown in FIG. 5, the wire harness 24 to which the guide member 10 is fixed has one end fixed to the vehicle body 28 and the other end to the vehicle body 28 in the front-rear direction (see FIG. 5). 5, the vehicle body 28 and the seat 30 are electrically connected to each other by being fixed to the seat 30 as a slide member that is slidable in the horizontal direction. The guide member 10 is disposed between the vehicle body 28 and the seat 30 such that the extending direction of the bottom plate portion 12 is along the moving direction of the seat 30 (left-right direction in FIG. 5). Further, the guide member 10 is disposed so that the tape adhering surface 18 of the bottom plate portion 12 faces outward by bending the wire harness 24 between the vehicle body 28 and the seat 30.

  In the wire harness guide member 10 having such a structure, the extending direction of the bottom plate portion 12 is arranged along the sliding movement direction of the seat 30. When the seat 30 slides, the bottom plate portion 12 is moved. It is curved and deformed in the extending direction. Thus, the bending direction of the wire harness 24 fixed to the bottom plate portion 12 is limited only to the moving direction of the seat 30 to avoid interference with peripheral members such as the guide rail 32 that guides the seat 30. 24 can be protected. Furthermore, since the wire harness 24 is sandwiched between the guide projections 14 on the side edges 20a and 20b of the bottom plate portion 12, the guide projection 14 can more reliably protect the wire harness 24 from contact with other members. In particular, since the guide protrusion 14 has a plate shape, the protection effect of the wire harness 24 can be effectively obtained. Since the guide member 10 is an integrally molded product made of a synthetic resin, it is possible to obtain a limiting effect and a protective effect in the bending direction of the wire harness 24 with a simple configuration and a small amount of forming material.

  And in the guide member 10 in this embodiment, the flat tape sticking surface 18 is formed over the whole back surface of the baseplate part 12. As shown in FIG. Thereby, the sticking area with the baseplate part 12 of the tape 26 which fixes the wire harness 24 can be ensured effectively, and the wire harness 24 can be stably fixed to the baseplate part 12 with the tape 26. Further, since the tape guide gap 22 is formed between the guide protrusions 14 adjacent to each other in the extending direction of the bottom plate portion 12, the tape 26 adhered to the bottom plate portion 12 is connected to the wire harness through the tape guide gap 22. 24 can be attached directly. Thereby, the baseplate part 12 and the wire harness 24 can be directly fixed without passing through the guide protrusion 14 etc., and the wire harness 24 can be stably fixed by the guide member 10. At the same time, even when the diameter dimension φ of the wire harness 24 is smaller than the projection height 14 h of the guide protrusion 14, the tape 26 can be securely attached to the wire harness 24, and the wire harness having various diameter dimensions can be obtained. Can be stably fixed. Further, since the guide protrusion 14 is tapered in the protruding direction from the bottom plate portion 12, the width dimension of the tape guide gap 22 in the extending direction of the bottom plate portion 12 is increased on the protruding tip side of the guide protrusion 14. Therefore, the tape 26 can be easily inserted into the tape guide gap 22.

  Furthermore, a plurality of guide protrusions 14 are formed at regular intervals in the extending direction of the bottom plate portion 12. Accordingly, a plurality of tape guide gaps 22 are formed at regular intervals in the extending direction of the bottom plate portion 12, and the tape 26 is substantially omitted in the extending direction of the bottom plate portion 12 by using these tape guide gaps 22 as marks. The wire harness 24 can be wound at equal intervals, the variation of the operator who winds the tape 26 can be suppressed, and the wire harness 24 can be more stably fixed.

  Next, FIG. 6 shows a fixed state of the wire harness guide member (hereinafter referred to as guide member) 40 as the second embodiment of the present invention to the wire harness 24. In the present embodiment, parts having the same structure as in the first embodiment are denoted by the same reference numerals as those in the first embodiment in the drawing, and the description thereof is omitted.

  In the guide member 40 of this embodiment, the guide protrusions 14 are alternately provided in the extending direction of the bottom plate portion 12 at both side edges 20a and 20b of the bottom plate portion 12, and staggered in the extending direction of the bottom plate portion 12. It is arranged in a shape. That is, in the width direction of the bottom plate portion 12 (left and right direction in FIG. 6), the guide protrusion 14 of one side edge portion 20a and the guide protrusion 14 of the other side edge portion 20b are not arranged to face each other. Only one is provided.

  In the guide member 40 having the structure according to the present embodiment, the number of the guide protrusions 14 can be reduced, and the formation material of the guide member 40 can be reduced. Further, the tape guide gaps 22 formed between the guide protrusions 14 and 14 are alternately positioned at both side edges 20 a and 20 b of the bottom plate part 12. Thus, the tape guide gap 22 formed on one side edge 20a of the bottom plate 12 and the tape guide gap 22 formed on the other side edge 20b are alternately arranged in the extending direction of the bottom plate 12. Thus, the tape 26 can be easily wound in an oblique direction in the extending direction of the bottom plate portion 12, and the tape 26 can be efficiently wound in the extending direction of the wire harness 24.

  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 guide protrusion is not limited in any way, and may be a rectangular plate shape or the like that protrudes from the bottom plate portion with a certain width dimension, and is not limited to the plate shape, and a cylindrical pin is formed from the bottom plate portion. You may project. Moreover, the arrangement | positioning space | interval of the guide protrusion in the extending direction of a baseplate part is not limited to the thing of the fixed space | interval like the said embodiment, The arrangement | positioning space | interval may be varied.

  Furthermore, the present invention is not limited to automobiles, and can be widely applied to aircraft, ships, various other transport machines, various machine tools, robots, and the like in which wire harnesses are routed.
