Abstract
The utility model discloses a kind of cable television service wires, it include inner conductor, inner conductor is coated with silicon rubber skeleton, silicon rubber skeleton includes inside and outside silicone rubber tube, multiple integrated silicon rubber parting beads are evenly spaced in inside and outside silicone rubber tube, the annular chamber formed between inside and outside silicone rubber tube is divided into multiple mutually independent isolating chambers by the silicon rubber parting bead, it is filled with nitrogen in the isolating chamber, compound inslation shielded layer, outer conductor, steel wire braid and external sheath layer are successively arranged with outside the silicon rubber skeleton.Silicone rubber tube and nitrogen are combined composition silicon rubber skeleton by the utility model, and the effect of insulation shielding is played while support, while using compound inslation shielded layer, more enhance the effect of shielding, suitable for the transmission of electronic signal, and laser propagation effect is good.
Description
Technical field:
The utility model relates to cable television signal transmssion line fields, relate generally to a kind of cable television service wire.
Background technique:
The structure of existing cable television service wire includes: inner conductor, and foamed insulation body is provided on the outside of inner conductor,
The external side of foamed insulation is provided with aluminium film, and the mesh grid made of 64 aluminum-magnesium alloy wires is provided on the outside of aluminium film.It is existing to have
For the shielding attenuation of line TV service wire in 70dB or so, shield effectiveness is poor, be not suitable for the transmission of digital signal, influences signal transmission
Quality.
Utility model content:
The utility model aim is exactly in order to make up the defect of prior art, to provide a kind of insulation shielding effect good wired
TV service wire.
The utility model is achieved through the following technical solutions:
A kind of cable television service wire, includes inner conductor, it is characterised in that: the inner conductor is coated with silicon rubber bone
Frame, silicon rubber skeleton include inside and outside silicone rubber tube, and multiple integrated silicon rubbers are evenly spaced in inside and outside silicone rubber tube
The annular chamber formed between inside and outside silicone rubber tube is divided into multiple mutually independent isolations by glue parting bead, the silicon rubber parting bead
Room is filled with nitrogen in the isolating chamber, be successively arranged with outside the silicon rubber skeleton compound inslation shielded layer, outer conductor,
Steel wire braid and external sheath layer.
A kind of cable television service wire, it is characterised in that: the compound inslation shielded layer includes mutually compound ternary
Ethylene-propylene rubber layer and nitrile rubber layer.
A kind of cable television service wire, it is characterised in that: carbon wave is equipped between the steel wire braid and external sheath layer
Line pipe.
The utility model has the advantages that:
Silicone rubber tube and nitrogen are combined composition silicon rubber skeleton by the utility model, and insulation screen is played while support
The effect covered, while compound inslation shielded layer is used, the effect of shielding is more enhanced, suitable for the transmission of electronic signal,
And laser propagation effect is good.
Detailed description of the invention:
