Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an information branch cable used for wiring an information cable such as a telephone or the Internet in a building such as a building.
[0002]
[Prior art]
When wiring information cables such as telephones and the Internet in buildings such as buildings on multiple floors, an information branch cable is constructed by providing a hanging support at the upper end of an information and communication trunk cable that bundles multiple information cables. Then, the hanging support portion is hung on a mounting bracket provided at the top of the building, and the information cable at the lower end portion is laid on each floor.
[0003]
In a conventional information branch cable, a hanging support portion is formed by bending a distal end portion of a support wire into a U-shape to form a hook, and a structure in which the root of the hook is crimped with a T-type terminal or a braided wire is used. The structure is used.
[0004]
However, in the case of a structure in which crimping is performed with a T-type terminal, the load strength with respect to its own weight is only about twice, and there is a drawback that the support wire comes off from the hook portion when the own weight increases.
[0005]
Further, a structure using a braided wire has a disadvantage that the structure is expensive.
[0006]
As a conventional information branch cable used in a building such as a building, there is, for example, a cable described in Patent Document 1.

[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an information branch cable which is inexpensive and can improve the load strength against its own weight.
[0009]
[Means for Solving the Problems]
An information branch cable according to the present invention includes an information communication trunk cable in which a plurality of information cables are bundled, and a suspension support for suspending and supporting the information communication trunk cable, wherein the suspension support includes an outer cover. The end of the support wire having the shape described above is bent into a U-shape to form a hook, the root of the hook is crimped with at least one T-shaped terminal, and the end of the support wire is peeled off to expose the support wire. Is crimped with a cylindrical crimp terminal.
[0010]
Further, when the root of the hook is crimped with the T-shaped terminal, the jacket at the crimped portion may be peeled off, and the exposed support wire may be crimped with the T-shaped terminal.
[0011]
Further, the base of the hook may be crimped in different directions by two T-shaped terminals.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0013]
FIG. 1 shows the configuration of an information branch cable used when wiring information cables such as telephones and the Internet in a building such as a multi-story building in the first embodiment of the present invention. This information branch cable is composed of an information communication trunk cable 12 in which a plurality of information cables 11 are bundled, and a hanging support 13 provided at an upper end of the information communication trunk cable 12.
[0014]
The hanging support 13 is hung on a mounting bracket 15 provided at the top of the building 14, and the information cable 11 at the lower end is wired on each floor.
[0015]
FIG. 2 is a side view showing the configuration of the hanging support portion 13 in FIG. 1, and FIG. 3 is a cross-sectional view taken along line AA 'in FIG. The hanging support part 13 bends a tip end of a support wire 23 in which a plurality of steel wires (seven wires in this example) are twisted and bundled and covered with a jacket 22 in a U-shape. Is crimped in two different directions using two T-shaped terminals 24 to form hooks 25. Further, the outer jacket 22 of the end of the support wire 23 is peeled off, and the exposed twisted steel wire 21 is connected to a cylindrical crimp terminal. It is configured by crimping at 26.
[0016]
In the information branch cable having the hanging support portion 13 having such a configuration, when the hanging support portion 13 is used while being hung on the mounting bracket 15 provided at the top of the building 14, a load is applied to the hook 25. When it is added, the cylindrical crimp terminal 26 provided at the end of the support wire 23 serves as a stopper, and the support wire 23 does not easily come out of the T-shaped terminal 24.
[0017]
That is, according to this embodiment, the load strength with respect to its own weight can be improved as compared with the related art. According to the experiments of the present inventors, it has been confirmed that the cable has a strength four times or more the weight of the cable. In addition, it can be manufactured at a lower cost than a structure using a braided wire.
[0018]
FIG. 4 is a side view showing the configuration of the suspension supporter 13 in FIG. 1 according to the second embodiment of the present invention, and FIG. 5 is a cross-sectional view taken along line BB 'in FIG. is there. In FIGS. 4 and 5, portions corresponding to those in FIGS. 2 and 3 are denoted by the same reference numerals, and description thereof will be omitted. Only different points will be described below.
[0019]
In the hanging support portion 13 in this embodiment, when the root of the hook 25 is crimped with two T-shaped terminals 24, the jacket 22 is peeled off at the crimped portion and the exposed stranded steel wire 21 is By crimping with the mold terminal 24, the load strength against its own weight is further improved.
[0020]
In the second embodiment, when the exposed stranded steel wire 21 is crimped with the T-shaped terminal 24, the stranded steel wire piece 21a whose coating has been peeled off is crimped in a state sandwiched between the pair of stranded steel wires 21. Although the case is illustrated, the twisted steel wire piece 21a may or may not be provided.
[0021]
Note that the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications are possible. For example, in each of the above-described embodiments, the case where the supporting wire 23 has a structure in which the twisted steel wire 21 in which a plurality of steel wires are twisted and bundled is covered with the jacket 22 has been described. A support line may be used.
[0022]
【The invention's effect】
As described above, according to the present invention, it is possible to provide an information branch cable which is inexpensive and can improve the load strength against its own weight.
