Abstract

PURPOSE:To effectively fix the cables to a cable supporting line without use of a particular skill. CONSTITUTION:A cylindrical piece 1 made of a thermocompressive plastic raw material is provided between a supporting line 20 and a cable 10 and a belt type piece 2 made of the thermo-shrinkable plastic raw material provided through the cylindrical piece is wound around the supporting line 20 and cable 10 and both ends thereof are overlapped with the cylindrical piece. The cylindrical piece and belt piece are thermally contracted integrally using a heating means such as a dryer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable support for maintaining a connection state of a connection end of a cable so that tension is not directly applied to the connection end between the cable end and a device or an extension cable. The present invention relates to a fixed support method for a wire.

[0002]

2. Description of the Related Art Conventionally, in a CATV line, for example, a coaxial cable connected to a pole device such as an amplifier is provided with a saran rope between the cable and a supporting wire at a certain distance in the vicinity of the end. By binding and fixing, the tension and other external forces do not act directly on the connecting portion between the cable end and the equipment, and thus the connection failure or disconnection of the cable is prevented.

[0003]

In the conventional example, a method of binding with a saran rope is adopted, but since the binding work is complicated and requires a special technique, a specific binding is required due to individual differences. In some cases, the force may not be obtained, and in other cases, the fixed state may not be maintained for a long time.

It is an object of the present invention to provide a method which eliminates the drawbacks of the conventional example.

[0005]

A cable is supported and fixed to a support wire by a heat-shrinkable plastics body, and a tubular piece made of a heat-shrinkable plastics material is interposed between the support wire and the cable. A band-shaped piece made of a heat-shrinkable plastics material penetrating the tubular piece is wound around the support wire and the cable, and both ends are inserted into the tubular piece to be polymerized, and then the tubular piece and the band-shaped piece are heated. Let it shrink.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of the present invention. FIG. 1 is a perspective view of a material used in the method of the present invention, and FIG. 2 is a perspective view of a material in which a tubular piece and a strip-shaped piece are assembled to a cable. 3 is a perspective view showing a supported and fixed state of the cable, and FIG. 4 is a partial front view of the CATV line.

The present invention uses a tubular piece 1 and a strip 2 as shown in FIG.

The cylindrical piece 1 is a cylindrical main body 1 made of plastics.
It is constructed by layering an adhesive material 3 which is melted by heating on the inner surface of a, and the tubular main body 1a is adapted to shrink in the radial direction by heating.

The strip 2 is formed by layering an adhesive material 3 which is melted by heating on one side of a plastic main body 2a. The main body 1a is made to shrink only in the longitudinal direction by heating. There is.

Then, as shown in FIG. 2, the tubular piece 1 is interposed between the supporting wire 20 and the cable 10, and the tubular piece 1
The supporting wire 20 and the cable 1 by penetrating the strip 2 in the
When wound around 0, the end portion is inserted into the tubular piece 1 to be polymerized, and heated by heating with a dryer or the like, the tubular piece 1 shrinks and solidifies in the radial direction, and the strip 2 shrinks and solidifies in the longitudinal direction.
Moreover, the adhesive 3 is melted and the cable 10 as shown in FIG.
Are supported and fixed to the support line 20.

Although at least the tubular piece 2 has a contracting function, the object of the present invention is usually achieved.
Also, by having this function, a stronger binding force can be obtained, which is effective when binding a plurality of cables at the same time.

A is a utility pole and B is an amplifier.

[0013]

Since the present invention is as described above, work can be performed easily and quickly without any special skill, so that the fixed state of the cable to the support wire is always stable and the work efficiency is improved.
