Description

[Detailed description of the invention] Industrial field of application: This invention relates to a fastener for communication lines.
In particular, the present invention relates to a fastening tool that is effective when used with thick support lines that are attached to communication lines and have relatively strong elasticity.

Prior Art and Problems to be Solved: For example, when a thick and highly elastic support wire as described above is used as a guide on the base body 1' of a conventional fastener as shown in FIG. A guide is one that has a flange on the top of the head and a guide part for the intended support wire between the flange and the base. The restraint was carried out by detouring or wrapping around the area. However, in recent years, as thicker and relatively more elastic support wires have come into use, these conventional fasteners have been prone to loosening and slipping due to the elasticity of the support wires. More and more inconveniences were occurring.

Means to solve the problem: This idea provides five guides on the base, each with its own shape and form, and the mutual cooperation of these guides allows for more solid three-dimensional retention than ever before. The details are as explained in the next example.

Embodiment: In FIGS. 1 to 4, 1 is a rod-shaped base with a generally circular cross section, 2 is a hanging ring protruding forward from this base, and on the base, in order from the rear, first A guide 3, a second guide 4, a third guide 5, a fourth guide 6, and a fifth guide 7 are provided. The first and second guides 3 and 4 each have a crown flange and are provided to protrude upward from the upper surface of the base body 1. Further, the third and fourth guides 5 and 6 are respectively a downward hook-shaped parietal flange 5',
6', and the guide path of the support line is located below the upper surface of the base body. Furthermore, the fifth guide 7 is provided with a downward hook-shaped crown flange 7', which projects upward from the upper surface of the base. In this example, the flanges of these guides are made to protrude in the same way symmetrically to the left and right sides of the base body, making it convenient for both right-handed and left-handed people to work, but they are arranged alternately on only one side. (See the section on the operation of this device below).
Reference numeral 8 denotes a guide section provided integrally with the front part of the fifth guide 7, and is wedge-shaped in cross section with a rounded front bud, so that the support line can be easily applied to this part. , and the contact area with the guide is made correspondingly larger. In addition, in this example, the intervals between each guide (a, b,
c, d) are taken so that a<b<c<d, which means that when the target support line is pulled in the direction of the arrow (Fig. 1) while being held in place, the holding force is concentrated at the rear of the base. This is because if the coating is spaced at equal intervals, the coating tends to be damaged, and it has been found that by doing so, damage can actually be reduced.

To use this tie-down, connect the support line of the communication line.
After a' is detoured along the guides 3 and 4 in a plane as shown in FIG. 1, it goes down over the upper surface of the base and is hooked onto the downward hook-shaped crown flange 5' of the guide 5.
Next, it descends over the upper surface of the base and is hooked onto the downward hook-shaped top flange 6' of the guide 6, and then, while being applied to the guide section 8, the downward hook-shaped top flange 7' of the guide 7 and the body of the base are hooked. It is guided between the surfaces and directed in the desired direction. As can be seen from the above explanation, in the present tool, the support line is three-dimensionally entwined with the base 1, and the support line is effectively held in place by the cooperation of each guide.

Effect of the invention: According to the fastening device of the present invention, the 5
Since it is held in place three-dimensionally by the guides, even if the target support line is thick, in effect,
It has been confirmed that it can be held in place in a much more stable manner than conventional types. In addition, one of the major advantages of this device is that the part of the core wire of the communication line that is separated from the support wire when securing is naturally shorter than that of the conventional type, which is secured in a flat manner. It is.
