2. Description of the Related Art Conventionally, for example, when a cable is laid in a conduit arranged in a wall, first, a nominal wire is inserted from one end of the conduit and pulled out to the other end, and then this nominal wire is inserted. After connecting the cable to the tip of the cable, the method of pulling the cable into the conduit to lay it by pulling back the nominal wire has been generally performed.

[0003]

However, in the case of a cable such as a light electric cable or an optical communication cable having a thin line and a weak tensile strength, when the cable is connected to the nominal line and pulled in, the cable may be broken due to the tension applied to the pulling line. However, there is a problem that the conventional laying method cannot be applied as it is.

Recently, different types of cables such as optical communication cables, weak electric cables, and high electric cables are often laid together in the same conduit, and when laying a plurality of cables, Or, when pulling out an old cable and updating the cable, there is a problem that the optical communication cable or the light electric cable is damaged.

The present invention has been made in view of such circumstances, and an object of the present invention is to reliably lay a laying path without damaging a cable such as a weak electric cable or an optical communication cable which is easily broken by tension. Another object of the present invention is to provide a cable housing laying tool that can be laid on a cable and does not cause a problem such as disconnection at the time of laying or updating.

[0006]

That is, as a means for solving the above-mentioned problems, a cable housing laying tool according to the present invention has a housing portion for housing a cable, and a laying path in a state where the cable is housed. It is characterized in that it is formed of a material having a rigidity capable of being fed into the inside.

[0007]

In this cable housing laying tool, the cable is protected by the housing portion and is made of a material having rigidity that can be fed into the laying path. Since the cable is not pulled and the cables do not rub against each other, it is possible to lay the cable in the laying path without worrying about damage or breakage of the cable.
