A kind of construction and decoration electric wire
Technical field
The present invention relates to a kind of cable, specifically a kind of construction and decoration cable belongs to Architectural Equipment field.
Background technique
Construction and decoration building site can often use a large amount of electric wire to construct, however a large amount of electric wire is disorderly random is covered with
Building site will cause using confusion, and effective method is to make electric wire be fixed on the body of rod by rope or other fixation devices at present
Or on other fixtures.
Summary of the invention
In view of the above existing problems in the prior art, the present invention provides a kind of construction and decoration cables, can directly fix
In on the body of rod or protrusion, it is convenient for wiring.
To achieve the goals above, the technical solution adopted by the present invention is that: a kind of construction and decoration cable, including oversheath
Layer and three electric wire cores, three electric wire cores are distributed in product shape, and the external sheath layer is in the ellipticity of semi-open-type, outside
Sheath includes the main part for accommodating three electric wire cores and the card base portion of main part two sides.
The every cable core includes the shielded layer of a conductor and a coating conductor ectosome, the electric wire core
Outside is filled with the magnesia for insulation.
The external sheath layer is made of polyvinyl chloride.
The oversheath is also implanted with a U-shaped skeleton, and the Liang Ge foot of U-shaped skeleton is embedded in card base portion.
The U-shaped skeleton is formed from steel.
The beneficial effects of the invention are as follows the ellipticity that external sheath layer is in semi-open-type, oversheath includes accommodating three electric wire wires
The main part of core and the card base portion of main part two sides, such design structure enable electric wire to block long column shape object, so that
Electric wire is imperious to be controlled, and such electric wire can also use in house decoration field, is especially routed this block, sometimes must
Need electric wire leakage, wiring can be achieved the purpose that by blocking outer fixture by the card base portion of main part two sides, and is not required to
The tools such as nail are wanted, it is beautiful and generous, wall is not destroyed, oversheath is also implanted with a U-shaped skeleton and makes the dynamics in card base portion bigger, electricity
Line is not easily to fall off.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1, external sheath layer, 2, core, 3, insulating layer, 4, card base portion, 5, U-shaped skeleton.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
As shown in Figure 1, a kind of construction and decoration cable includes external sheath layer 1 and three electric wire cores 2, three electric wire cores
2 are distributed in product shape, and the external sheath layer 1 is in the ellipticity of semi-open-type, and external sheath layer 1 includes accommodating three electric wire cores
Main part and main part two sides card base portion 4.
The every cable core 2 includes the shielded layer of a conductor and a coating conductor ectosome, the electric wire core 2
Outside be filled with for insulation magnesium oxide insulated layer 3.
The external sheath layer 1 is made of polyvinyl chloride.
The oversheath is also implanted with a U-shaped skeleton 5, and the Liang Ge foot of U-shaped skeleton 5 is embedded in card base portion 4.
The U-shaped skeleton 5 is formed from steel.
Oversheath includes the main part for accommodating three electric wire cores and the card base portion of main part two sides, such design structure
Enable electric wire to block long column shape object, controlled so that electric wire is imperious, such electric wire can also be led in house decoration
Domain uses, and is especially routed this block, sometimes has to electric wire leakage, blocks outer fixation by the card base portion of main part two sides
Object can achieve the purpose that wiring, and not need the tools such as nail, beautiful and generous, not destroy wall, and oversheath is also implanted with
One U-shaped skeleton makes the dynamics in card base portion bigger, and electric wire is not easily to fall off.
