  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
Drawing 1 is a figure showing the form of utilization of the cable protector concerning a 1st embodiment.

  The cable protector 1 protects the cable 2 laid on the ground, and is disposed so as to cover, for example, each end portion of the conventional protective cover 3 that covers the portion of the cable 2 near the tree.

  Ants descending on the protective cover 3 from the tree try to move to a place without the protective cover 3 and reach the cable protector 1, but the cable protector 1 moves to the portion of the cable 2 not covered by the protective cover 3. Movement is prevented. Thereby, an ant does not blow the cable 2, and can protect the cable 2 from damage of an ant. Of course, the ant cannot enter the protective cover 3 by the cable protector 1.

  In the underground, ants can move in the soil and the like, so the cable protector 1 is suitable for protecting cables on the ground.

  2A and 2B are diagrams illustrating the configuration of the cable protector 1, in which FIG. 2A is a side view and FIG. 2B is a front view. In addition, illustration of the protective cover 3 is abbreviate | omitted in FIG.

  The cable protector 1 includes a base member 11 whose position is fixed to the cable 2 and a plurality of bristle materials 12 that are pre-planted in the base member 11. The base member 11 is a metal braided wire or the like, and a linear bristle material 12 is planted in the central portion excluding its end portion. The bristle material 12 in the center is planted from the base member 11 uniformly and in the circumferential direction, that is, has a shape like a brush for washing the container. The length of the central portion, that is, the brush portion is, for example, about 200 to 300 mm. The length of each end is, for example, about 50 to 100 mm. The length of the bristle material 12 is, for example, about 30 to 50 mm.

  Each end is wound around the cable 2, thereby fixing the position of the base member 11 with respect to the cable 2. It is also possible to fix the position of the cable 2 by winding the brush portion in a spiral shape.

  In this way, the bristle material 12 is arranged so as to be uniform from the cable 2 toward the circumferential direction.

  Next, the operation of the cable protector 1 will be described.

  Ants that have entered the cable protector 1 are considered to be blocked by the bristle material 12 and move to a place without the bristle material 12, but the bristle material 12 is arranged uniformly around the cable 2, so it is difficult to move. Therefore, it becomes difficult to move the cable 2 to the exposed portion (the portion without the protective cover 3).

  Ants have the property of favoring upward movement, and thus can be expected to move (climb) toward the tip of the bristle material 12. Such an action also has an effect of making movement difficult.

  FIG. 3 is a diagram showing the cable protector used for investigating how much time the ant advances in the cable protector 1 in what time.

  The length of the brush part was 160 mm, and an ant was placed at the center point. Two types of cable protectors 1 having different bristle lengths d were used.

  FIG. 4 is a diagram showing the results of the investigation.

  The length d of the bristle material was set to 30 mm, and five investigations were performed. From the first time to the fourth time, the ants did not reach the end within 30 minutes and moved by the distance shown. In the fifth time, the ants reached the end in 10 minutes 14 seconds.

  In addition, the length d of the bristle material was set to 50 mm, and five investigations were performed. In the second and third times, the ants did not reach the end within 30 minutes and moved by the illustrated distance. In the first, fourth and fifth times, the ants took the time shown (within 30 minutes) and reached the end.

  Therefore, it turns out that the cable protector 1 has the effect which prevents an ant's movement.

  As shown in FIG. 5, if the initial position of the ant in the above investigation is C, the probability distribution of the position where the ant reaches within a certain time is a normal distribution. Therefore, for example, when there is a concern that the moving distance of the ants increases due to the number, type, season, etc. of the ants, the brush portion can be simply lengthened, and thus the effect can be easily improved.

[Second Embodiment]
FIG. 6 is a perspective view showing a cable protector according to the second embodiment.

  The base member 11 is a tube that can contain a cable, and the bristle material 12 is implanted on the outside of the tube. The tube is configured to open at one place in the circumferential direction, and to close each end of the open portion by catching each other. Therefore, the cable protector can be easily attached in a short time, and the degree of freedom of installation can be improved. Also, even if the cable is bent slightly, the cable protector cannot be removed easily, and it can be installed on a cable that is swayed by the wind. In addition, since the cable is included, the cable protector also serves as a protective cover and can prevent the cable from being rubbed against wood.

  In addition, it is good also as fixing each other with an adhesive tape etc. instead of hooking each edge part of the open part.

[Third Embodiment]
FIG. 7 is a perspective view showing a cable protector according to the third embodiment.

  The base member 11 is in the form of a sheet, and a bristle material 12 is planted on one surface of the base member 11 and entangled with the bristle material 12 so as to stick to the bristle material 12 (not shown; hereinafter referred to as bristle material 12A). ) Is implanted on the other side. The cable protector is similar to what is called velcro tape or magic tape, and the bristle material 12 has a mohair or loop shape.

  The base member 11 is wound around a cable (not shown) with one side facing outward, the base member 11 is overlapped at the end of winding, and the overlapping bristle material 12 and bristle material 12A are bonded to each other. The position of the member 11 is fixed.

  Although the bristle material 12 is mohair or looped, the action which prevents the movement of an ant by the bristle material 12 is the same, and the same movement prevention effect can be acquired.

  Further, the cable protector can be easily attached in a short time, and the degree of freedom of installation can be improved. Also, even if the cable is bent slightly, the cable protector cannot be removed easily, and it can be installed and protected even on cables that sway in the wind. In addition, since the cable is included, the cable protector also serves as a protective cover and can prevent the cable from being rubbed against wood.

  Such mohair or loop-like bristle material 12 may be used for the cable protector of the first embodiment or the second embodiment.
