  The present invention relates to a cable carrier that holds various cables such as a power cable and a signal cable.

  A cable carrier is used to hold a cable that supplies electric power, a signal, a fluid, and the like to various actuators and the like provided on a reciprocating movable body (for example, Patent Documents 1 to 3). . A conventional cable carrier generally has a configuration that can accommodate a cable only on one side of a base portion extending along the cable, so that it is difficult to obtain a sufficient accommodation space, and a cable accommodated in a stacked state. There was a problem that abrasion was likely to occur due to friction between each other.

  On the other hand, Patent Document 4 discloses a cable carrier in which U-shaped cable guides are inserted alternately in the vertical direction with respect to a thin plate to form a cable housing space on both surfaces of the thin plate. According to such a configuration, although the accommodation space can be increased, not only the work of alternately arranging the cable guides up and down is complicated, but also the cable guides are easily rubbed and worn when the cable carrier is bent. was there. In addition, when it becomes necessary to change the width of the thin plate according to the width and the number of cables to be accommodated, it is necessary to newly prepare a cable guide having the same width as the width of the thin plate, which increases the manufacturing cost. There was also a problem.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view showing a guide member of a cable carrier according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG. The cable carrier 1 of the present embodiment is configured such that the holding portion 22 of the guide member 20 shown in FIGS. 1 and 2 is attached to the edge portion of the belt member 10 as indicated by an arrow in FIG. The belt member 10 is a flexible belt-like member formed by cutting a sheet base material into a strip shape, for example. A plurality of engagement receiving portions 12 that can be engaged with the guide member 20 are provided at equal intervals according to the size of the guide member 20 at both side edges in the width direction of the belt member 10. In the present embodiment, the engagement receiving portion 12 is formed of a through hole, and can be formed using water jet processing or laser processing. The belt member 10 can be formed of a resin material having excellent tensile strength, such as modified polyphenylene ether (PPE) or PA (polyamide), and preferably reinforced with glass fiber, aramid fiber, carbon fiber, or the like. be able to. Although only a part of the belt member 10 is shown in FIG. 3, the length of the belt member 10 is the length of a power cable, a signal cable, a fluid tube, or the like that connects a fixed body such as a machine body and a movable body. It can be set appropriately according to the situation.

  As shown in FIGS. 1 and 2, the guide member 20 has a shape in which both end portions of a strip-shaped main body 21 are bent so as to face each other, and stands up from the approximate center of the main body 21. A sandwiching portion 22 is formed. The sandwiching portion 22 includes a first sandwiching piece 23 and a second sandwiching piece 24 that are spaced apart from each other, and a belt member between the first sandwiching piece 23 and the second sandwiching piece 24. Ten edges can be clamped. The opposing clamping surfaces 23a, 24a of the first clamping piece 23 and the second clamping piece 24 are formed with a slight inclination so that the gap formed between them is the narrowest at the center and the sides are slightly wider. Thus, the belt member 10 can be securely clamped even when the belt member 10 is bent and deformed.

  On the clamping surface 23a of the first clamping piece 23, there is provided an engaging portion 23b made of a convex portion protruding toward the clamping surface 24a of the second clamping piece 24. The engaging portion 23 b is sized to be able to engage with each engaging receiving portion 12 formed on the belt member 10. On the other hand, a concave groove 24b is formed on the clamping surface 24a of the second clamping piece 24 at a position where the engaging portion 23b faces. The depth of the concave groove 24b is such that when the edge of the belt member 10 is inserted into the pinching portion 22, the belt member 10 bends and passes through the concave groove 24b so that the engaging portion 23b can be easily avoided. It is preferable.

  Both sides of the clamping part 22 in the main body 21 constitute a first holding part 25 and a second holding part 26, respectively. The first holding portion 25 and the second holding portion 26 extend upright in opposite directions from the holding portion 22, and the distal end side is bent in the same direction as the first holding piece 23 and the second holding piece 24. doing. The width of the first holding part 25 rising from the first holding piece 23 is constant without changing from the base end side toward the distal end side, while the second holding part rising from the second holding piece 24 The width of 26 is formed so as to taper from the proximal end side toward the distal end side.

  The guide member 20 having the above configuration is integrally formed of a resin material having excellent compressive strength, such as polyamide (PA), polypropylene (PP), polybutylene terephthalate (PBT), acrylonitrile butadiene styrene copolymer (ABS). It is possible.

  The cable carrier 1 according to the present embodiment is a cross-sectional view shown in FIG. 4 by sequentially engaging the engagement portions 23b of the plurality of guide members 20 with the engagement receiving portions 12 formed on both sides of the belt member 10 in the width direction. 1, the first holding portions 25, 25 and the second holding portions 26, 26 arranged on both sides of the belt member 10 face each other, and hold the cable 40 on both the upper and lower surfaces of the belt member 10. be able to. Therefore, manufacture is easy and the accommodation space efficiency of the cable 40 can be improved. The cable 40 held by the cable carrier 1 is preferably a flat cable having a plurality of assembly wire cores 42. After the cable carrier 1 is assembled, the cable 40 is bent in the width direction to form the first holding portion 25. , 25 and between the second holding portions 26, 26, and can be clamped. As the flat cable, for example, a plurality of sheaths or tubes made of synthetic resin or the like can be used, which are integrated in parallel by extruding all together, bonding with an adhesive, heat fusion, or the like.

  Each guide member 20 mounted on the belt member 10 is positioned and fixed in a state where the adjacent portions are in close contact with each other as shown in FIG. 5 by inserting the engaging portion 23 b into the engagement receiving portion 12. Therefore, even if the cable carrier 1 is repeatedly bent by a reciprocating motion of a movable body (not shown) to which the end of the cable is attached, the adjacent guide members 20 and 20 are merely brought into close contact with and separated from each other. Thus, since relative movement does not occur, wear due to rubbing can be suppressed, and durability can be maintained well.

  Further, since the second holding portion 26 is tapered, the cable carrier 1 is placed so that the second holding portion 26 is closer to the curved center side than the first holding portion 25 as shown in FIG. By arranging, rubbing between the guide members 20 can be suppressed even during bending. When the cable carrier 1 is greatly bent, the adjacent second holding portions 26 and 26 can be in contact with each other to prevent further bending, and an excessive bending load is applied to the accommodated cable. Can be prevented from occurring. Further, since the first holding part 25 has a constant width, it is difficult to bend the cable carrier 1 in the direction opposite to the bending direction of the cable carrier 1 shown in FIG. .

  Further, as shown in FIG. 2, the guide member 20 has a concave groove 24 b formed at a position facing the engaging portion 23 b formed of a convex portion in the sandwiching portion 22, so that the belt member 10 is inserted into the sandwiching portion 22. Thus, the engaging portion 23b can be quickly and easily engaged with the engaging receiving portion 12 of the belt member 10, and the engaged state can be reliably maintained after the engagement.

  Further, by changing the width of the belt member 10, it is possible to cope with various flat cables having different widths without changing the shape of the guide member 20, so that the manufacturing cost can be reduced. The cable 40 accommodated in the cable carrier 1 is preferably a flat cable that is easily held by the guide member 20 and hardly rubs between the cables, but is not necessarily limited to this, and other cables are used. There may be. When there is a possibility that the cable may fall off the guide member 20 by using a cable other than the flat cable, as shown in FIG. 6, the first holding portions 25 and 25 and the second holding portion 26 that face each other. , 26 are provided with locking portions 28, 28, respectively, and a transition member 50 such as a belt is detachably provided between the locking portions 28, 28, whereby the cable 40 can be reliably held.

  In the present embodiment, the engagement receiving portion 12 of the belt member 10 is formed from a through hole, and the engagement portion 23b of the guide member 20 is configured from a convex portion. Other configurations may be used as long as they can be fixed securely. For example, the engagement portion 23b may be a through hole or a recess, while the engagement receiving portion 12 may be a protrusion.

  Further, in the present embodiment, since the second holding portion 26 located on the opposite side of the engaging portion 23b across the second holding piece 24 is formed to be tapered, as shown in FIG. When the second holding portion 26 is bent so as to be on the bending center side of the cable carrier 1, the belt member 10 is pressed against the first holding piece 23 shown in FIG. 4 by bending deformation. Therefore, even when the cable carrier 1 is bent, the engagement portion 23b can be prevented from being unexpectedly detached from the engagement receiving portion 12, and the engagement state can be reliably maintained. However, it is also possible to form the first holding portion 25 to be tapered so that the first holding portion 25 is located on the curved center side of the cable carrier 1.
