Abstract
The utility model relates to a cable for transmitting cable television signals, which is to resolve the technical problem that the provided cable should have the characteristics of high-quality and high-strength signal transmission with less damages and that the cable can realize direct overhead installation, save installation cost, and reduce installation workload. The technical proposal is the employment of a self-bearing video double-row wire, and a shielding layer made of metal material is arranged coaxially around the directing line in the center of each wire. Insulating material is arranged between each directing line and each shielding layer, and each shielding layer is coated with a coating which is made from insulating material. The double-row wire comprises two wires of the structure, and the coatings of the two wires are connected together, and the two wires are arranged in parallel. A support line is also arranged outside the double-row wire, and the core of the support line is made of metal, and the coating of the support line is made from insulating material and is connected with the coatings of the two wires.
Description
Technical field
The utility model relates to a kind of signal cable, in particular for the cable of cable TV signal transmission.
Background technology
Along with economy, fast development of society, TV particularly cable TV is popularized in China.The cable that existing transmission cable TV signal is used, its structure all is a single-core line, promptly the screen that coaxial arrangement one metal material is made around the lead of cable center is isolated with insulating material between lead and the screen, and the foreskin that the periphery of cable also adopts insulating material to make coats.The cable of this kind structure during the transmitting multi-path video signal, causes between the signal easily to interfere with each other, thereby influences signal quality at the same time.In addition, the tensile strength of this kind cable is limited, needs ad hoc support track strengthening when outdoor built on stilts layout, has not only increased installation cost, and has increased installation workload and installation period.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of improvement of vision cable is provided, and this cable should have signal transmission quality height, intensity height, not fragile characteristics, and can directly make somebody a mere figurehead installation, save installation cost, reduce installation workload.
The technical solution adopted in the utility model is: self-bearing type video biserial line, the screen that coaxial arrangement one metal material is made around the lead at every line center, isolate with insulating material between lead and the screen, coatedly also make of insulating material at the outer field foreskin of screen, this biserial line comprises the line of two said structures, and the foreskin of two lines fuses, and two line parallels are arranged.
This biserial line Support Level that also is arranged in parallel outward, the core of Support Level adopts metal material, and the foreskin of Support Level is also made of insulating material and is fused with the foreskin of aforementioned two lines.
The biserial line that the utility model provides is arranged in two coaxial vision cables together, not only reduces interfering with each other between the signal when the transmitting multi-path video signal, improves transmission quality effectively, also helps the secret effect that improves transmission signals; In addition, set up Support Level after because the tensile strength of video line significantly strengthens, can directly use, and need not to add any reinforcing material, thereby significantly save installation cost as overhead wire, reduced installation workload.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As seen from the figure: self-bearing type video biserial line, the screen 3 (generally being that aluminium foil adds woven wire) that coaxial arrangement one metal material is made around the lead 1 at every line center, isolate with insulating material 2 (using the plastics of polyethylene and so on usually) between lead 1 and the screen 3, the coated insulating material making of also using PE plastics and so at the outer field foreskin 4 of screen, this biserial line comprises the line of two said structures, and the foreskin of two lines fuses, and two line parallels are arranged.
This biserial line Support Level that also is arranged in parallel outward, the core 5 of Support Level adopts metal materials, and the foreskin 6 of Support Level is also made of insulating material and is fused with the foreskin of aforementioned two lines; Can be on equipment during manufacturing once the property moulding pull out.
Claims (2)
1. self-bearing type video biserial line, at the lead (1) at the every line center screen (3) made of coaxial arrangement one metal material on every side, isolate with insulating material (2) between lead and the screen, coatedly also make of insulating material at the outer field foreskin of screen (4), it is characterized in that this biserial line comprises the line of two said structures, and the foreskin of two lines fuses, and two line parallels are arranged.
2. self-bearing type video biserial line according to claim 1, it is characterized in that this biserial line Support Level that also is arranged in parallel outward, the core of Support Level (5) adopts metal material, and the foreskin of Support Level (6) is also made of insulating material and fused with the foreskin of aforementioned two lines.
