Description

Multiple clamp for communication cable {MULTI-CLAMP FOR COMMUNICATION CABLE}

The present invention relates to a multiple clamp for a communication cable, and more particularly, to a multiple clamp for a communication cable capable of fixing a plurality of optical cables on an outer circumferential surface of a pole.

Currently, optical communication is widely used for high speed internet communication.

The optical communication uses an optical cable for transmitting information. Since the optical cable is a cable for transmitting light, it is difficult to handle the optical cable as compared with a general telephone line or an electric wire.

For example, a common wire or a telephone wire has a problem that it is not difficult to transmit electric signals even if there is a slight bend, but communication data may be lost because the optical cable can not transmit light.

For the optical communication, an optical cable is required to be connected from a telephone office to each home. Normally, the optical cable is connected to each household through several electric poles.

Meanwhile, when the optical cable is stretched, the weight of the optical cable is increased to cause disconnection, or the height of the optical cable may be increased There is a problem in that it can be damaged by hanging on a freight car which is high.

In order to solve the above problem, as shown in FIG. 10, an optical cable fixing means for holding and fixing the optical cable 5 to the electric pole 7 is mounted on the outer peripheral surface of the electric pole 7, 10, the optical cable fixing means includes an arm tie band 101 mounted on the outer circumferential surface of the electric pole 7, (1) coupled together with the optical cable (5) in a state of being mounted opposite to each other in the radial direction of the electric wire (7), thereby fixing the optical cable (5) to the outer peripheral surface of the electric pole And a cable clamp 103.

However, in the conventional optical cable fixing means, only one pair of cable clamps 103 can be mounted on one arm tie band 101, which means that three or more optical cables 5 can not be mounted.

In addition, in order to additionally install the optical cable 5, there is a problem that the installation cost is increased because the arm tie band 101 equipped with the cable clamp 103 is additionally mounted on the electric pole 7, There is a problem that the appearance of the electric pole 7 can be damaged by the optical cable fixing means attached to the electric pole.

Further, after the installation of the optical cable fixing means, it is also difficult to remove the optical cable fixing means fixed to the top of the electric pole 7.

On the other hand, as a prior art of the present invention, a "support device for a wire" of Patent Publication No. 10-2014-0042265 has been filed and disclosed. The support device for a wire has an insertion groove, A bracket part for supporting both sides of the insulation part so that the insertion groove part is positioned in the longitudinal direction; and a fixing part which is fixed to the side surface of the bracket part and which is installed in a shape to surround the circumference of the electric pole, .

Korean Patent Publication No. 10-2014-0042265 (Apr. Korea Patent Registration No. 10-1330668 (2013.11.19)

In addition, the present invention provides a multiple clamp for a communication cable, which can reduce installation or demolition costs by simply installing or demounting a cable clamp for holding and fixing an optical cable to an electric pole, .

Another object of the present invention is to provide a multiple clamp for a communication cable which does not damage the beauty of the electric pole when a plurality of optical communication cables are installed on the upper outer peripheral surface of the electric pole.

In order to achieve the above object, a multiple clamp for a communication cable according to the present invention is characterized by comprising a steel wire cable into which a steel wire is drawn and a multiple clamp for a communication cable for holding and fixing an optical cable integrally coupled with a steel wire cable on an outer circumferential surface of the steel wire cable, A fixing member having both ends thereof protruding from the outer periphery of the electric pole and threaded on an outer peripheral surface of the electric pole so as to penetrate the outer peripheral surface of the electric pole in a radial direction of the electric pole, A clamp fixing bolt penetrating through the base plate in a direction toward the other side of the base plate from one side of the base plate facing the electric device base, And a clamp fixed to the clamp fixing bolt, And the nut is fastened between the base plate and the clamp. When the nut is tightened between the base plate and the clamp, the space between the base plate and the clamp becomes narrow and the clamp binds the steel wire cable. As a result, An optical cable integrated with the cable is fixed.

The multiple clamp for a communication cable according to the present invention having such a structure is characterized in that a pair of base plates facing each other in the radial direction of the electric pole are installed on the electric pole without installing a plurality of arm tie bands having cable clamps on the outer peripheral surface of the electric pole A plurality of clamps can be additionally mounted on the base plate, and a plurality of optical communication cables can be fixed to the electric pole.

Further, according to the present invention, a plurality of clamps can be additionally mounted on the base plate only by fixing a pair of base plates to the outer circumferential surface of the electric pole, so that installation and dismantling are easy, and installation or demolition costs can be reduced.

In addition, when a plurality of optical communication cables are installed on the outer circumferential surface of the top of the electric pole, the beauty of the electric pole can be avoided.
