Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a telephone prefabricated cable used in an apartment house or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3 (shown in a diagram for easy understanding), a plurality of, for example, three telephone cables are provided in accordance with the number of floors of an apartment house. a1, a
2, a3 is twisted by a twisting machine around a suspension line b having a vinyl coating on a steel wire, and then the telephone cable a1 is untwisted. c, c
And then fixed to the suspension line b with a bind wire or the like.

[0003] Next, the telephone cable a2 is untwisted, cut from the tip by a length (2d) twice as long as the distance d, and then processed into two branch portions c, c. It was fixed to the hanging wire b.

Next, the telephone cable a3 is untwisted,
After being cut from the tip by a length (4d) four times the distance d, the two branch portions c, c were processed, and then fixed to the suspension line b with a bind wire or the like.

Therefore, there are the following problems. As can be seen from the description of this example, the telephone cables a2, a
In case 3, the length is 6 times (6d) the distance d.
The occurrence of cable waste increases the number of floors of the apartment house, and the number of telephone cables and branches increases the generation of cable waste. In a specialty factory, every time an order is received, processing such as twisting and branching of a telephone cable is performed in accordance with the number of floors of an apartment house, etc., so that prior processing cannot be performed.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the problems described in the prior art, and is capable of performing processing such as branching processing in advance and generating unnecessary cable waste. -To provide a method for processing bulls.

[0007]

SUMMARY OF THE INVENTION A method for processing a prefabricated telephone cable according to the present invention comprises the steps of: providing a plurality of telephone cables provided with a predetermined number of branch portions at predetermined intervals from an upper end to a lower portion; After the branching portions of each telephone cable are assembled so as to be arranged at the predetermined interval, a hanging line is arranged at substantially the center of the assembly so that each telephone cable has slack, It is characterized by being fixed to the suspension wire by a fastener.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1 (shown in a diagram for easy understanding), a telephone cable is used. 1
a, 1b, and 1c are arranged at predetermined intervals d from the upper end to the lower end.
A predetermined number of branch portions 2a and 2b are provided in advance.

The telephone cables 1a, 1b and 1c are cables having the same specifications, and are general-purpose communication cables such as CPEV and CQEV.
Bull is used. (Not shown)

[0010] In the ordinary apartment house, the predetermined interval d is as follows.
2.7 to 2.8 m is standard. The standard of the branch line from the branch parts 2a and 2b is 2P or 1Q, and the length is about 1 to 4 m. For example, if the branch line is 2P, the telephone case
Bulls 1a, 1b, 1c have a CPEV (0.5 mm x 4
P) etc. are used. If the branch line is 1Q, CQE
V (0.5 mm × 2Q) or the like is used.

The telephone cables 1a, 1b, 1c are processed in advance in the branching sections 2a, 2b, regardless of whether or not an order has been received, and are stored in a drum wound state. Therefore, at the time of branch processing, the telephone cables 1a, 1b, 1
No c debris is generated.

Next, for example, when an order is received from an apartment house that requires six branches, the telephone cables 1a, 1 which have been subjected to branch processing in advance and stored in a drum winding.
As shown in FIG. 2 (for ease of understanding, FIG. 2 shows a diagram b, 1c) at the predetermined interval d at the branching portions 2a, 2b of the telephone cables 1a, 1b, 1c. , Array and aggregate.

Next, the hanging wire 3 provided at the same time is inserted substantially in the center of the set, and the telephone cables 1a, 1b, 1c are connected to the hanging wire 3.
In contrast, for example, the SZ is meandered so as to be slackened, and is fixed to the hanging wire 3 by a fastener 4 such as a binding band.

With such a slack, the finished telephone prefabricated cable of the present invention can be wound around a drum and transported to the site of use.

In the lower part where three telephone cables 1a, 1b, 1c are assembled, for example, as shown in FIG. 1a, 1
A spacer 7 having a notch 6 for fitting b and 1c
It is convenient to mount the telephone cables 1a, 1b, and 1c in the notches 6 of the spacer 7 in advance by appropriately attaching a suitable number of the cables to the suspension lines 3 in advance.

In this embodiment, for ease of understanding, a case has been described in which three branch cables are provided in advance for three telephone cables, but the present invention is not limited to this. -The number of cables and branches is free to increase.

[0018]

Since the present invention is configured as described above, it has the following effects. Branch processing can be performed in advance regardless of whether or not an order has been received. No cable debris during branch processing. Can respond to orders with short delivery times. There is no need for large equipment such as stranded wire machines.
