Description

  The present invention relates to a communication cord attaching device for attaching a communication cord to a building when performing network wiring in the building.

  FIG. 3A is a front view showing exposed wiring using a conventional wire protector, and FIGS. 3B and 3C are partially cutaway perspective views showing different examples of the conventional wire protector. That is, after fixing the wire protector main body 12 to the wall 11 in the building using a double-sided tape, a nail or the like, the optical cable 13 is accommodated in the wire protector main body 12 and the cap 14 is put over and wired (for example, (See Patent Documents 1 and 2.) In such a construction method, it is necessary to cut the optical cable in accordance with the length of the wiring route before construction. After wiring, both ends must be terminated (connector is attached on site). At that time, the extra length of the optical cable must also be processed. In addition, when the wiring plan is to be changed once the construction is completed, in most cases, the length adjustment and extra length processing of the optical cable must be performed again.

  4A is a perspective view showing a conventional optical staple, and FIG. 4B is a front view showing an exposed wiring using the conventional optical staple. That is, the optical staple 22 is fixed to the wall 21 in the building along the wiring route. Thereafter, the optical cable 23 is fixed (gripped) to the optical staple 22 in a state of being stretched along the wiring route. Thus, the optical cable 23 is directly fixed to the wall 21 using the optical staple 22 (see, for example, Patent Document 3). In such a construction method, as in the case of using a wire protector, there are problems such as length adjustment, extra length processing, and difficulty in coping with changes after construction.

  FIG. 2 is a front view showing a construction example of the communication cord attaching device according to the embodiment of the present invention. As shown in FIG. 2, two attachment device main bodies 31 and one attachment device main body 41 are used, and the attachment device main bodies 31 and 41 are bent and attached to the wall of the building at 90 °. A plurality of cord attachment members 51 are movably provided in the guide grooves 32 and 42 of the attachment device bodies 31 and 41. Using the plurality of cord attachment members 51, the light curl cord 61 having springiness is bent and attached to 90 °. Optical connectors (SC / MU) 62 and 63 for the optical curl cord 61 are provided, and the optical connectors (SC / MU) 62 and 63 are light provided to the optical cords 66 and 67 via adapters 64 and 65, respectively.
