BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clamp type cable using a half-hoop flexible support member, and more particularly to a clamp type cable having a clamp for repeatedly reciprocating a feeder, a feeder, Type cable.

In addition, the present invention is also applicable to a clamp type cable which performs repetitive reciprocating movement with a relatively short distance by using a half-arc-shaped flexible supporting member instead of using a cable duct, a cable tray or a multi- Which prevents twisting and twisting of a wire or an air hose inserted into the hose.

Modern society is a highly developed industrial society, and many high-performance products such as ultra-precision parts, displays, smart phones, computers, semiconductors, automobiles, and aircraft are being produced, and new products are being continuously researched and developed.

Industrial machines such as display panel manufacturing equipment, semiconductor chip manufacturing equipment, machine tools, industrial robots and the like are used for mass production or processing of specific products, Picked up, transported, processed, and the like.

Here, the equipment for repeatedly exercising in an industrial machine is used by connecting a flexible cable (hereinafter referred to as a "cable") such as a power cable, a wire cable for supplying a power source, a liquid or gas, or various fluid supply hoses to a jacket.

At this time, for repeated operation of the mechanical equipment of the industrial machine, a cable jacket for supplying power to the equipment to be supplied at all times is also moved together with the equipment, and the cable jacket usually has a "⊃" And move it repeatedly.

On the other hand, as the apparatus is continuously operated, excessive twisting, twisting, and pulling are generated in the cable jacket connected thereto, thereby damaging the cable jacket and causing the appearance to be broken.

Therefore, there is a method of protecting a cable or a hose by using a flexible conduit, an underground conduit, a cable duct, and a supporting member to solve the problem of such a cable.

However, in the above method, a separate duct and duct are purchased and installed, which is costly. In the case of a cable that repeatedly reciprocates a relatively short distance, it is difficult to install a duct or insert a support member It is necessary to develop technology for this.

The following are conventional prior art related thereto.
