Abstract
The utility model relates to a transmitting line which can transmit a radio frequency signal and a digital signal at the same time. The utility model aims at solving the technical problem of providing a transmitting line which can transmit the radio frequency signal and the digital signal at the same time. In addition, the utility model can reduce the work load of installation and improve the working efficiency of installation. The utility model adopts the technical proposal that the utility model is a combined digital television network line which comprises a radio frequency signal line and a data signal line. The external parts of the radio frequency signal line and the data signal line are respectively covered by the wrapping fur made of an insulating material, and the wrapping furs of the radio frequency signal line and the data signal line are connected and integrated. The radio frequency signal line and the data signal line are aligned together in parallel.
Description
Technical field
The utility model relates to a kind of signal transmssion line, especially simultaneously the transmission line of transmitting radio frequency signal and digital signal.
Background technology
Along with economy, fast development of society, cable TV is popularized in China; Network application is also just arrived huge numbers of families with unprecedented speed expanded; At present, these two kinds of facilities have become the indispensable facility of buildings such as most apartments, residential building, commercial building, hotel.Yet, be two kinds of lines independently mutually at present as the line of the line of transmitting radio frequency signal and transmission of digital signals; During installation pipeline, threading can only be installed respectively, not only make troubles to installment work, and workload is bigger, the operating efficiency during installation is also low.
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 holding wire is provided, this holding wire should have the characteristics of transmitting radio frequency signal and digital signal simultaneously, and can reduce installation workload, improves installment work efficient.
The technical solution adopted in the utility model is: Digital television network split line, comprise rf signal line and digital signal line, the outside of described rf signal line and digital signal line is coated with the foreskin that insulating material is made respectively, and the foreskin of described rf signal line and digital signal line links into an integrated entity.
Described rf signal line is in the same place with the digital signal line parallel arranged.
Because the Digital television network split line that the utility model provides fuses two kinds of lines, only need bury a pipeline underground when mounted, wear single line; Thereby workload reduces greatly, and installment work efficient significantly improves.And this assemble line can be on equipment once the property moulding pull out, the foreskin of two kinds of lines is an integral body, connects close and firm, production cost is also descended.Has vast market prospect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As seen from the figure: Digital television network split line comprises rf signal line 7 and digital signal line 1.Described rf signal line is identical with the structure of existing conventional rf signal line, is with one heart coated successively insulating material 5, screen 6 (generally adopting aluminium foil to add woven wire) and foreskin 7-1 in copper core 4 peripheries; The described digital signal line also structure with the existing conventional digital signal line is identical, can be the six roots of sensation or eight by the coated heart yearn 3 of metal screen layer 2 (generally adopting woven wire to add aluminium foil), and metal screen layer 2 peripheries also use foreskin 1-1 coated.
Foreskin 7-1 in the utility model and foreskin 1-1 are the homogeneity insulating material (being generally the PVC plastics) that fuses; Extrusion molding together on same equipment during production, thus rf signal line and digital signal line are united two into one, and parallel arranged is together.Because the more existing holding wire of this assemble line structure had variation, so production equipment needs in addition simple refit; Those skilled in the art can be competent at repacking work.
Claims (2)
1. Digital television network split line, comprise rf signal line (7) and digital signal line (1), the outside of described rf signal line and digital signal line is coated with the foreskin that insulating material is made respectively, it is characterized in that the foreskin (7-1) of described rf signal line and the foreskin (1-1) of digital signal line link into an integrated entity.
2. Digital Television combinational network winding thread according to claim 1 is characterized in that described rf signal line (7) and digital signal line (1) parallel arranged together.
