Abstract

The utility model discloses a smart home television cable. The smart home television cable comprises a conductor, an insulator, shielding layers and an outer sheath, wherein the insulator wraps the conductor, the shielding layers wrap the insulator, the outer sheath wraps the shielding layers, i.e., the conductor, the insulator, the shielding layers and the outer sheath are sequentially arranged along the radial direction from the inside to the outside. The smart home television cable adopts aluminium foils and a braiding double-layer or four-layer shielding structure, thus having strong disturbance resistance; a polyethylene material is adopted, and quick transmission speed is realized; the transparent polyvinyl chloride (PVC) sheath with high tensile strength and high elongation has good wear resistance and long service life; the smart home television cable is a special cable for a cable television, which is specially designed and produced for the broadband internet access of digital televisions, high definition televisions, network televisions, three-dimensional (3D) televisions, cable televisions and the like; and the smart home television cable can transmit digital signals, has the characteristic impedance of 75 ohms, is used in the environments with temperatures of minus 25 DEG C-70 DEG C, and can be laid in an exposed or concealed manner, is directly buried or is used for home theater systems.

Description

A kind of Smart Home tv line

Technical field

The utility model relates to electric wire, is specifically related to a kind of Smart Home tv line.

Background technology

Existing Smart Home tv line comprises conductor, insulator, outer conductor and oversheath, and its anti-interference is poor, and the life-span is short, and more and more universal along with electrical equipment requires also increasingly high for the interference free performance of electrical signal, transmission speed, life-span etc.

The utility model content

In order to reach above-mentioned purpose, the utility model provide a kind of interference less, loss is little, speed is high and the life-span is long Smart Home tv line.

The utility model is designed a kind of Smart Home tv line; Comprise conductor, insulator, screen and oversheath; Described conductor is wrapped up by insulator, and insulator is by several layers screen parcel, and outermost screen is wrapped up by oversheath; Described screen is made up of inner shield aluminium foil and weaving shielded metal net, and weaving shielded metal net is wrapped in outside the inner shield aluminium foil.

Described screen is 2 layers, and the first inner shield aluminium foil that is wrapped on the insulator is the single face aluminium foil, and it is online to be wrapped in the first weaving shielded metal, is two-sided aluminium foil by the second inner shield aluminium foil of the second weaving shielded metal net parcel simultaneously.

Described oversheath adopts transparent PVC or PVP to be made, and it has high-tensile, high elongation rate, the advantage that the life-span is long.

Described oversheath inner surface is provided with the grid line, and its parcel screen is compacter, can improve shield effectiveness, multiple colour systems such as that oversheath can also be made into as required is orange, blueness and silver gray.

What described conductor adopted is the high purity oxygen free copper conductor, and what the insulator of parcel conductor adopted is high foaming rate physical blowing polyethylene.

The beneficial effect of the utility model: adopt aluminium foil to add the double-deck or four layers of shielding construction of braiding, high percentage of braiding coverage tinned wird braid shielded, shield effectiveness is good, and antijamming capability is strong; Adopt the high purity oxygen free copper conductor, transmission attenuation is little, loss of signal is little; Adopt high foaming rate physical blowing polythene material, more low transmission decay, more high transmission speed; Employing has the transparent PVC protective cover material of high-tensile high elongation rate, has good resistance to wear, can resist oil, acid, alkali, bacterium, moisture, anti-aging, long service life.
