Abstract
The utility model discloses a high-fidelity telephone line, which comprises two copper conductors arranged in parallel, wherein a reinforced wire core is arranged between the two copper conductors; the outer side of the copper conductor is sequentially wrapped with an insulating layer and a shielding layer; the outer side of the reinforced wire core is wrapped with a PE sheath; the outer side of the two copper conductors and the reinforcing wire core is also wrapped by an outer sheath; the upper surface and the lower surface of the outer sheath are provided with grooves which are respectively positioned right above and right below the reinforced wire core, and the telephone wire has good shielding effect and high strength.
Description
Technical Field
The utility model relates to a telephone line field especially relates to a high-fidelity telephone line.
Background
The conventional telephone line is basically an RVV cable, and the RVV electric wire cable is formed by adding a layer of sheath on two or more RV lines, so that the telephone line with the structure is easily interfered and has insufficient strength to meet the requirements of current users.
Chinese patent CN202796232U discloses a novel galvanized iron wire home telephone wire, which adds a galvanized iron wire reinforced core structure in a sheath, has the characteristics of high strength and convenient overhead installation, and is very suitable for areas with unchanged traffic, such as mountainous areas
The telephone line is laid in the house in the empty state, so that the method is economical and practical; however, this patent has a problem of poor interference resistance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the shortcoming of prior art, providing a high-fidelity telephone line that shielding effect is good, intensity is high.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that:
a high fidelity telephone line comprises two copper conductors which are arranged in parallel, wherein a reinforced wire core is arranged between the two copper conductors; the outer side of the copper conductor is sequentially wrapped with an insulating layer and a shielding layer; the outer side of the reinforced wire core is wrapped with a PE sheath; the outer side of the two copper conductors and the reinforcing wire core is also wrapped by an outer sheath; grooves are formed in the upper surface and the lower surface of the outer sheath and are respectively located right above and below the reinforcing wire core.
Preferably, an aluminum-plastic composite tape longitudinal cladding layer is further arranged between the insulating layer and the shielding layer.
Preferably, the diameter of the reinforced wire core is smaller than that of the copper conductor, and the thickness of the PE sheath is not more than 0.6 mm.
The utility model has the advantages that:
firstly, the method comprises the following steps: the shielding layer and the aluminum-plastic composite belt longitudinal cladding layer are utilized, so that the shielding performance of the telephone line can meet the expected requirement, and the fidelity is good;
secondly, the method comprises the following steps: the arrangement of the reinforced wire core ensures the strength of the whole telephone line, and is convenient for erection and laying;
thirdly, the method comprises the following steps: the outer sheath is provided with a groove which is convenient for being laid together with other cables after being bound.
