Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail, focusing on the parts necessary to understand the operation and action according to the present invention.

1 is a perspective view of a cable-less wiring device according to a first embodiment of the present invention, Figure 2 is a cross-sectional view of a cable-less wiring device according to a first embodiment of the present invention, Figures 3 and 4 It is an experimental diagram of a cable arrangement for pipeless wiring according to the first embodiment of the.

1 to 4, the cableless wiring device 100 according to the first embodiment of the present invention includes a conductor part 110, an insulation part 120, a ground part 130, a bedding part 140, It is configured to include a protection unit 150 and the sheath unit 160.

The conductor part 110 is formed of a metallic material having conductivity and transmits electricity and a signal. The conductor part 110 may be formed of at least one copper copper wire. The conductor unit 110 may configure the thickness of the copper copper wire or the number of copper copper wires in consideration of the magnitude of the voltage flowing through the signal, the strength of the signal, and the like.

The insulating part 120 is formed of a non-conductive material while surrounding the conductor part 110 to insulate the electricity and the signal. The insulator 120 may include a fireproof part 121 and an insulator part 122.

The fireproof part 121 may be formed of a nonmetallic material while surrounding the conductor part 110 to be well formed to withstand heat generated in the conductor part 110. In other words, the fireproof part 121 may be designed to withstand heat generated by electricity or a signal flowing through the conductor part 110 for a predetermined time. Therefore, the fireproof part 121 is preferably made of a material containing a Mica material that can withstand heat of 800 ~ 1000 ℃ or more.

The insulator part 122 is formed of an insulator material while surrounding the fireproof part 121 to insulate the electrical and signal. That is, the insulator portion 122 is formed of a non-conductive material through which no signal communicates with electricity, thereby preventing the electricity and the signal flowing through the conductor portion 110 from being connected to the outside.

In this case, the insulation unit 120 may be extrusion-processed the insulation material of the crosslinked polyethylene compound system.

The ground unit 130 is positioned in contact with the insulation unit 120 to maintain a constant potential between the conductor unit 110 and the ground. The ground unit 130 may prevent overheating due to a missing wire, a short circuit, an overload, or the like, by maintaining the same potential between the conductor unit 110 and the ground.

The reason why the ground portion 130 is formed while contacting the insulation portion 120 is that the conductor portion 110 is destroyed when the insulation portion 120 is destroyed by overheating due to a missing, a short circuit, or an overload. ) And the ground unit 130 are to be automatically electrically connected. As such, when the insulating part 120 is broken and the conductor part 110 and the ground part 130 are electrically connected quickly, the power side breaker is quickly cut off. Accordingly, since the power supply side breaker is quickly cut off, it is possible to prevent a fire from occurring due to overheating of the conductor part 110.

The bed 140 is formed of a material having elasticity while surrounding the insulating part 120 and the ground part 130 to mitigate an external shock to protect the insulating part 120 and the ground part 130. The bed 140 may surround the insulation 120 and the ground 130, and may be formed to be solid so that the insulation 120 and the ground 130 do not move. Accordingly, the state where the ground portion 130 and the insulation portion 120 are in contact with each other can be easily maintained.

In addition, since the bedding part 140 is formed of an elastic material even when an impact is generated from the outside, the bedding part 140 is quickly dispersed and absorbed, thereby insulating the insulating part 120 and the ground part 130 located inside the bedding part 140. Can be supported stably.

In addition, the bedding unit 140 may include the TPE, which is a material having good abrasion resistance, to more stably support the insulating unit 120 and the grounding unit 130.

The protection part 150 surrounds the bedding part 140 and is formed of a tin plating material to protect the bedding part 140 from external trauma. The protection part 150 is formed of a tin plated material, but is formed while wrapping the bed 140 in the form of a rigid braided screen, it can protect the bed 140 from physical harm. That is, by being formed in the form of a rigid braided screen, the mechanical strength is improved to be able to stably protect the bedding unit 140 from physical harm such as animals or insects.

In addition, since the protection part 150 is formed of a tin plating material, bendability and workability may be improved.

The sheath portion 160 is formed while surrounding the protection portion 150 while maintaining a constant thickness. The sheath unit 160 should primarily protect the conductor unit 110, the insulation unit 120, the ground unit 130, the bedding unit 140, and the protection unit 150 described above from the outside. Accordingly, the sheath unit 160 may be configured by mixing FR-PVC, TPU, etc., which are excellent in moisture resistance, waterproofness, flame retardancy, and toxicity, while being resistant to UV exposure.

For example, the outdoor cable shown in (a) of FIG. 2 is composed of an excellent moisture resistance and a TPU, which is a waterproof material for protecting the insulation and internal insulation by UV exposure due to solar radiation, as an address material. In addition, the indoor cable shown in (b) of FIG. 2 may be configured by mixing FR-PVC, which is a material having excellent flame retardancy and toxicity, as an address material.

As such, by using a material having excellent flame retardancy and toxicity, not only the fire-free cable wiring device 100 is damaged but also no combustion toxicity occurs.

In addition, since the sheath portion 160 is exposed to the outside, the interior of the sheath portion 160 is protected and at the same time the landscape of the building is considered. Accordingly, it is preferable to vary the color, pattern, etc. of the sheath portion 160 to produce.

Experimental results of the cable-free wiring cable apparatus 100 according to the first embodiment of the present invention described above are as follows.

First, FIG. 3 is an experiment in which the conductor part 110 and the grounding part 130 positioned inside the bedding part 140 are spaced apart at regular intervals, and FIG. 3 (a) shows an equipotential diagram. 3 (b) shows the strength of the battlefield.

4 is an experiment in which the conductor part 110 and the ground part 130 positioned inside the bedding part 140 are brought into close contact with each other, and FIG. 4 (a) shows an equipotential diagram. (b) shows the strength of the battlefield.

As shown in Figs. 3 and 4, the strength of the strongest electric field is 1.60 [dl / m]. That is, it can be seen that 1.60 [V / mm]. At this time, the insulation strength of the insulation portion 120 is approximately 25.1 ~ 27.5 [mm / mm]. Here, if the insulation strength of the insulation portion 120 is applied to approximately 25.1 [kW / mm], the voltage at which insulation is broken may be 25.1 / 1.60 = 15.7 [kW].

At this time, since the actual breakdown voltage test reference value is 16 [kV / m], it can be seen that the conductor part 110 and the ground part 130 are in close contact with each other and are formed in contact with each other through the test result.
