Description

Technical Field [0001] The present invention relates to a wire bonding device for a communication cable,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique used for installing a communication cable using a wire string, more specifically, to a wire bonding apparatus for a communication cable which is inserted into an end portion of a wire bundle and a communication cable at one time, .

Generally, a communication cable is connected to a building such as a home or an office through a telephone pole, and is installed in a suspended state by using a ring which is installed at regular intervals in a horizontal line installed between telephone poles.

In the prior art 1 for installing a communication cable in a wire line, the communication cable is inserted into the elastic ring by spreading an elastic ring formed by staggering the upper end, and then the upper end of the elastic ring is hooked on the wire.

However, in this prior art 1, in order to install the elastic ring at a constant interval to the joint line, it is necessary to install the communication cable while hanging the elastic ring on the joint line while repeating movement and stopping along the joint line by using the crane vehicle, There is a problem that a lot of time is required for the installation work.

Conventional technique 1 relies on the naked eye of the worker to adjust the spacing of the elastic rings constantly and does not have a restraint mechanism capable of maintaining the interval constantly. Therefore, when the wire and communication cable are shaken by strong winds, There is a problem that a deflection of the communication cable occurs at a portion where the interval of the elastic ring is greatly widened.

In order to overcome such a problem, Japanese Patent Application No. 10-2011-0043299 (hereinafter referred to as " Prior Art 2 ") proposes that a helical steel wire is installed on a wire and a communication cable and then pulled.

However, in the prior art 2, when the steel wire is installed on the wire and the communication cable, the wire and the communication cable can be inserted into the steel wire only after the wire and the communication cable are inserted into the end of the wire wound spirally, There is a problem that it is very troublesome.
