The present invention relates to a multipurpose coaxial cable and a crime prevention system using the same. Since the present invention integrates various uses in one product, the present invention can be used in various products, and is particularly applicable to a crime prevention and prevention system.

The coaxial cable has a copper wire in the center and is insulated around the insulator. Around the insulator, there is a conductor shielded in the shape of a net made of copper or aluminum, and the conductor which forms the core with the outer shielding layer of the net forms a concentric circle. It is called a coaxial cable and is used for a line such as a TV antenna, high-speed data communication, a cable TV, a local area network (LAN), and the like.

As shown in FIG. 1, a conventional coaxial cable has a conductive wire (1) made of copper, which has good electrical conductivity, a polyethylene (PE) insulating layer (2) surrounding the conductive wire (1), and the PE. Shielding layer (3) made of a conductive material such as copper or aluminum wrapped around the surface of insulating layer (2), and PVC (Polyvinyl chloride) coating layer (4) covering and finishing the outside of the shielding layer (3) It is disclosed that consists of.

The PE insulating layer (2) formed between the conductive wire (1) and the shielding layer (3) made of the above conductive material insulates the conductive wire (1) and the shielding layer (3) of (+) and (-). By preventing electromagnetic interference from occurring, it serves to transmit a relatively stable signal from external radio interference or noise, and the PVC coating layer 4 serves to protect the coaxial cable by blocking the external environment.

However, in the case of the conventional coaxial cable, the inside of the PE insulation layer 2 wrapping the conducting wire 1 is densely formed without pores due to its material characteristics, so that it is not completely protected from external interference or noise. This has been.

In the PE insulating layer (2), at least one or more pores (2a) is formed by artificially formed to be symmetrical or asymmetrical with respect to the conducting line (1) is disclosed, bar of the pores (2a) If the number is one, the pores are not formed in the area opposite to the conduction line 1, so the conduction line 1 is eccentric with time, so that at least two pores are formed. There is this.

The prior art having the above configuration prevents the interference of radio waves flowing through the conducting wire 1 and the shielding layer 3 by the PE insulating layer 2, and the PE insulating layer 2 Air in the pores (2a) formed in the interior of the secondary insulation buffer effect is to act to effectively remove the noise of the radio wave. In addition, since the pores 2a are formed inside the PE insulating layer 2, since the material enters less than before, the manufacturing cost can be reduced economically.
