Description

  The present invention relates to a cable introduction structure.

  In recent years, in a control room in an intelligent building or the like, air conditioning is operated throughout the year in order to manage heat generated in heat generating parts such as various devices and cables. Such a comfortable temperature space is suitable for nesting of mice. Therefore, mice prefer to enter the control room. The intruding mouse often hides in the heat generating part, obtains a comfortable temperature, and rests.

  On the other hand, mice have a habit of anterior teeth called incisors that continue to grow. Therefore, if the hard teeth are not chewed and the incisors are not kept worn down, the mouth may not be closed or opened, resulting in starvation. Due to this behavior, the rat bites the sheath of the cable and sharpens or scrapes the incisors with the metal part of the cable.

  Some cables are introduced into cable introduction holes at the bottom of the building floor. The introduced cable is crawled to relevant locations to enable power supply and communication. Therefore, when the cable is bitten by a mouse, a short circuit (short circuit) or an electric leakage occurs. First, there is a fire due to electrical leakage, which is the top cause of fire. In addition, examples of malfunctions include meltdown problems due to malfunction of the cooling system at the Fukushima nuclear power plant, train and train stoppages, ETC billing system malfunctions on expressways, and computer system failures at various companies. The impact of stopping the current digital society is occurring everywhere.

  On the other hand, in order to prevent such problems, construction work such as inserting a fender brush into the cable introduction hole or closing the cable introduction hole with a foamed urethane spray agent has been performed.

  However, since the conventional construction work using the fender brush uses a sharp metal brush needle, the operator's finger may be damaged.

  Moreover, the conventional construction work using foamed urethane may be incomplete when the rat bites the foamed urethane to prevent the entry of the mouse.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a cable introduction structure that can prevent a mouse from entering a cable introduction hole without damaging an operator's fingers.

  The cable introduction structure according to the present invention includes a casing having a cable introduction hole communicating with a cable introduction path, a fixing plate fixed to the casing and blocking a part of the cable introduction hole, and a detachable attachment to the fixing plate. A movable plate that is freely attached and moves in a moving direction that intersects the extending direction of the cable introduction hole, thereby allowing the cable to be introduced into the cable introduction path, the fixed plate, and the movable plate Fixing means for fixing the casing to which the plate is attached to the cable introduction path, and the fixed plate and the movable plate are in a state where the casing is fixed to the cable introduction path, A plurality of elements are alternately arranged along a direction intersecting the moving direction.

  Hereinafter, the form for implementing this invention is demonstrated. In addition, embodiment described below shows an example of embodiment of this invention, and, thereby, the range of this invention is not interpreted narrowly.

  FIG. 1 is a diagram illustrating a cable introduction structure according to an embodiment of the present invention. FIG. 2 is a perspective view showing the shape of the housing. FIG. 3 is a perspective view showing how the movable plate moves. FIG. 4 is a perspective view showing the shape of the tip of the movable plate. FIG. 5 is a perspective view showing a cable introduction path in which a cable introduction structure according to an embodiment of the present invention is installed.

  As shown in FIG. 1, the cable introduction structure 1 includes a housing 2, a fixed plate 3, a movable plate 4, and fixing means 5.

  The housing 2 is installed in the cable introduction hole IH shown in FIG. The housing 2 is covered with, for example, an aluminum plate on wood, and has a main body 20 and a flange 21 as shown in FIG. The main body 20 is formed in a frame having a substantially rectangular opening (not shown). As shown in FIG. 1, the flange portion 21 is formed with a hole H1 for inserting the fixing means 5 into a concrete surface or the like.

  The fixing plate 3 is formed by covering an aluminum plate on wood, for example. As shown in FIG. 1, the fixing plate 3 is fixed to the housing 2 in a bowl shape. As shown in FIG. 1, the fixing plate 3 closes a part of the cable introduction hole IH (see FIG. 5). The term “detachable” as used in the present invention includes attachment using a fitting structure in addition to attachment using a fastener such as a screw.

  The movable plate 4 is made of aluminum, for example, and is detachably attached to the fixed plate 3 as shown in FIG. As shown in FIG. 3, the movable plate 4 allows the cable C to be introduced into the cable introduction path IP (see FIG. 5) by moving in the movement direction DM. The moving direction DM is a direction intersecting with the extending direction of the cable introduction hole IH (see FIG. 5), and in this embodiment, the direction perpendicular to the extending direction of the cable introduction path IP (see FIG. 5). And As shown in FIG. 3, when the movable plate 4 is moved upward, a hole H2 communicating with the cable introduction hole IH (see FIG. 5) communicating with the cable introduction path IP (see FIG. 5) is formed.

  As shown in FIG. 3, the movable plate 4 is movable along the movement direction DM according to the diameter of the cable C introduced into the hole H2. “According to the diameter of the cable” means that the movable plate 4 moves upward as the number of the cables C introduced into the hole H2 increases.

  As shown in FIG. 3, the movable plate 4 rises by a height corresponding to the diameter of the cable C introduced into the hole H2. As shown in FIG. 1, a mark 40 is provided on the surface of the movable plate 4. As shown in FIG. 1, the marks 40 of the present embodiment are provided at four locations at equal intervals along the movement direction DM. The mark 40 is easily distinguished from other parts of the movable plate 4 by, for example, painting in red. This mark 40 is a line and can recognize the number of cables C introduced into the hole H2 (see FIG. 3). In addition, you may add a character and a symbol to this line. This makes it easier for the operator to visually recognize the number of cables C loaded.

  The positions P1, P2, P3, and P4 of the mark 40 shown in FIG. 1 serve as a standard indicating the number of cables C introduced into the hole H2 (see FIG. 3). That is, if the position P1 of the mark 40 and the position of the surface S1 of the flange portion 21 coincide with each other, it indicates that the number of cables C introduced into the hole H2 (see FIG. 3) is zero. If the position P2 of the mark 40 and the position of the surface S1 of the flange portion 21 coincide with each other, it indicates that the number of the cables C introduced into the hole H2 (see FIG. 3) is one. If the position P3 of the mark 40 and the position of the surface S1 of the flange portion 21 coincide with each other, it indicates that the number of cables C introduced into the hole H2 (see FIG. 3) is two. If the position P1 of the mark 40 coincides with the position of the surface S1 of the flange portion 21, it indicates that the number of cables C introduced into the hole H2 (see FIG. 3) is three. When the cable C is introduced into the hole H2 (see FIG. 3), the movable plate 4 cannot be lowered downward and is placed on the cable C in a state of being kept up.

  As shown in FIG. 3, a hole 41 for inserting one screw B (see FIG. 1) is provided in the upper part of the movable plate 4. A hole (not shown) corresponding to the hole 41 is also provided on the housing 2 side. As a result, the movable plate 4 can be detached from the housing 2 simply by pulling out the screw B (see FIG. 1) driven into the housing 2 via the movable plate 4. Furthermore, when the cable C is introduced, the hole H2 (see FIG. 3) can be greatly opened, and the workability of the cable introduction work can be improved.

  As shown in FIG. 4, the lower end portion 42 (tip portion) of the movable plate 4 is folded back to the inner side (upper side) of the movable plate 4. A convex rounded folded edge 43 is formed at a portion in contact with the cable C. Thereby, for example, when a large earthquake or the like occurs, there is no possibility that the cable C is cut and damaged due to contact with the lower end portion 42. Further, even if there is a burr at the lower end portion 42 of the movable plate 4, since the rounded folded edge 43 is formed, there is no possibility that the cable C is damaged due to contact with the burr.

  The fixing means 5 is, for example, a concrete screw that is screwed into the concrete body CS (see FIG. 5), an anchor bolt that is driven into the concrete body CS (see FIG. 5), or the like. The fixing means 5 fixes the flange portion 21 of the housing 2 to which the fixed plate 3 and the movable plate 4 are attached to the cable introduction path IP (see FIG. 5).

  As shown in FIG. 1, the six fixed plates 3 and the five movable plates 4 alternate along the direction intersecting the moving direction DM in a state where the housing 2 is fixed to the cable introduction path IP. Is arranged. In the present embodiment, the direction intersecting the movement direction DM is a direction perpendicular to the movement direction DM.

  As shown in FIG. 1, the five movable plates 4 are rectangular plate-shaped members having a long side portion and a short side portion. The length of the short side portion varies depending on the type of the cable C. That is, each of the five movable plates 4 has a different width. Note that “depending on the type of cable” means that separate movable plates 4 are prepared in accordance with the diameters of various cables such as a single-core cable, a multi-core cable, a coaxial cable, and an optical cable.

  As described above, in the construction of the cable introduction structure 1 according to the present embodiment, since a sharp brush needle like a conventional fender brush is not used, there is no possibility that an operator's finger is damaged during construction.

  Further, according to the cable introduction structure 1 according to the present embodiment, since the housing 2 is made of a combination of, for example, aluminum and wood, there is a risk that even if it is bitten by a mouse, a hole can be easily opened like conventional urethane foam. There is no.

  Further, according to the cable introduction structure 1 according to the present embodiment, it is possible to prevent a mouse from entering the cable introduction hole IH without damaging the operator's fingers.

  As described above, the cable introduction structure of the present invention has been described based on the embodiment. However, the specific configuration is not limited to this embodiment, and the invention according to each claim of the utility model registration request is not limited to this embodiment. Design changes and additions are allowed without departing from the gist.
