Abstract
The utility model relates to a signal transmission wire, particularly to a radio-frequency cable combination wire with a plurality of signal transmission channels, and aims to provide an improved signal wire. The signal wire is provided with a plurality of channels capable of transmitting video signals simultaneously, and can reduce the interference between single cables, reduce the expense for execution and improve the construction efficiency. The signal transmission wire adopts the technical scheme that the radio-frequency cable combination wire comprises radio frequency signal wires each ofwhich is formed through concentrically cladding an insulating material layer, a shielding layer and a wrapper in sequence from inside to outside around the periphery of a core wire. The radio-frequency cable combination wire is characterized in that the combination line comprises the four radio frequency signal wires on the outer surface of which a sheath for wrapping the four radio frequency signal wires is arranged.
Description
Technical field
The utility model relates to a kind of signal transmssion line, specifically is a kind of radio frequency cable assemble line with a plurality of signal transmission passages.
Background technology
Along with economy, fast development of society, use the sub-district of vision signal and office building also more and more.In the video signal system that prevails in urban construction or transformation, rf signal line all is the single sheath that is provided with, and when actual installation, the workmen need be at each root cable additional layer sleeve pipe; When inserting many rf signal lines, then need to lay respectively.The operation of laying cable is many, the time is long, and operating expenses is also big, causes the cost of engineering to improve.
The utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of holding wire is provided, and this holding wire should have several passages of transmission video signal simultaneously; And can also reduce interference between the single cable, reduce operating expenses, improve efficiency of construction.
The technical solution adopted in the utility model is: a kind of radio frequency cable assemble line, comprise rf signal line, this rf signal line is with one heart coated from inside to outside successively insulation material layer, screen and foreskin in the heart yearn periphery, it is characterized in that comprising altogether in the described assemble line four rf signal lines, the outer surface of these four rf signal lines also is provided with the sheath of four rf signal lines of a parcel.
Above-mentioned a kind of radio frequency cable assemble line, as preferably, described four rf signal lines are arranged in parallel.
Above-mentioned a kind of radio frequency cable assemble line as preferably, also is provided with a plastic film layers between described four rf signal lines and the sheath.
The cable group zygonema that the utility model provides fuses four rf signal lines, only needs when mounted to lay a pipeline, reduces workload widely, and installment work efficient significantly improves; Simultaneously, also reduce difficulty of construction, reduced the interference between the single cable.In addition, can be on equipment when this cable group zygonema is produced once the property moulding pull out, the foreskin of whole cable forms an integral body; Owing to also be provided with plastic film layers in the whole cable group zygonema, four rf signal lines in the assemble line interconnect close and firm, and production cost is also descended; Thereby has a vast market prospect.
Description of drawings
Fig. 1 is a perspective view of the present utility model.
Embodiment
Below by specific embodiment the technical solution of the utility model is described further.
As seen from the figure: a kind of radio frequency cable assemble line, comprise rf signal line, included rf signal line is identical with the structure of existing conventional rf signal line, is coated with one heart successively insulation material layer 1b, screen 1c (generally adopting aluminium foil to add woven wire) and foreskin 1d in the periphery of heart yearn 1a (generally being copper heart yearn).
Improvement of the present utility model is: comprise four rf signal lines 1,2,3,4 in this cable group zygonema, the outer surface of these four rf signal lines also is provided with a sheath 6, and four rf signal lines are bundled together.Four rf signal lines fuse, and only need when mounted to lay a pipeline, reduce workload widely, and installment work efficient significantly improves; Simultaneously, also reduce difficulty of construction, reduced the interference between the single cable.
As further improvement of the utility model, described four rf signal lines are arranged in parallel.
Further improve as of the present utility model, also be provided with a plastic film layers 5 between described four rf signal lines and the sheath, make closely to connect mutually between this cable group zygonema; This cable group zygonema is made also simple, can extrusion molding together on same equipment during production, thus be arranged in parallel together; Production equipment only needs in addition simple refit.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Claims (3)
1, a kind of radio frequency cable assemble line, comprise rf signal line (1), this rf signal line is with one heart coated from inside to outside successively insulation material layer (1b), screen (1c) and foreskin (1d) in heart yearn (1a) periphery, it is characterized in that comprising in the described assemble line four rf signal lines (1,2,3,4), the outer surface of these four rf signal lines also is provided with the sheath of four rf signal lines of a parcel.
2, a kind of radio frequency cable assemble line according to claim 1 is characterized in that described four rf signal lines are arranged in parallel.
3, a kind of radio frequency cable assemble line according to claim 1 and 2 is characterized in that also being provided with a plastic film layers (5) between described four rf signal lines and the sheath.
