Description

[Detailed Description of the Invention] The present invention relates to a communication cable that is routed on the floor.

FIG. 1 is a cross-sectional view of the structure of a conventional communication cable installed on a floor or the like. A communication line formed by providing an insulator 4 on the outer periphery of a conductor 3 is housed in a wire protector 1 in contact with the floor surface, and is covered with a wire protector cover 2.

However, this structure has the disadvantage that the wire protector cover 2 is easily removed by external force when it is installed on the floor. Also, when installing the
The disadvantage is that it has poor workability due to its structure.

FIG. 2 is a cross-sectional view of a communication cable whose structure is simplified to facilitate installation workability. Protective jacket 5 integrally formed with a central partition
This configuration has a communication line inside. This communication cable is excellent in that the internal communication wires are protected from external forces and in the installed appearance, but when the internal communication wires are exposed during the installation work, the protective jacket 5 must be peeled off and removed. The problem is that it is not easy.

An object of the present invention is to provide a communication cable for floor wiring which eliminates the above-mentioned drawbacks, has good protection against external forces, and is easy to install.

The communication cable for floor wiring of the present invention includes a protective jacket that protects the communication line from external forces, and in the communication cable in which the communication line is provided inside the protective jacket, the communication cable comes into contact with the floor surface of the protective jacket. It is characterized by having a flat bottom and a continuous notch groove in the longitudinal direction of the outer surface of the bottom.

Hereinafter, embodiments of the present invention will be described based on the drawings. 3 and 4 are cross-sectional views of floor wiring communication cables showing different embodiments of the present invention, and the same parts or parts that act in the same way as in FIGS. 1 and 2 are denoted by the same reference numerals. It is attached. 6 is
This is a notch groove that is continuously provided in the longitudinal direction of the flat bottom outer surface of the protective jacket 5 that contacts the floor surface.
This notch groove 6 is provided at a depth that allows the protective jacket 5 to be easily torn off using a cutting tool such as a nipper during the installation operation of the communication cable.
The end portion of the communication cable can be peeled off and removed to expose the communication line while separating the cable.

FIG. 3 shows an embodiment in which the protective jacket 5 has a partition to form two hollow parts, each of which accommodates a communication line, and the outer surface of the bottom of each hollow part has a respective communication line. Two notch grooves 6, a total of four grooves 6, are provided.

FIG. 4 shows an embodiment in which one hollow part is formed by the protective jacket 5 and two communication lines are housed in the hollow part, and two notches are provided on the outer surface of the bottom of the hollow part. A groove 6 is provided.

In this manner, by providing the notch grooves corresponding to each hollow portion, the protective outer covering can be easily peeled off and removed. Moreover, by providing the notch groove in the flat bottom that contacts the floor surface, sufficient strength can be provided against external pressure.

As explained above, according to the present invention, it is possible to reliably protect communication lines from external forces such as external pressure and friction, and the practical effects of being able to perform the installation work easily and with a good appearance can be achieved.
