Abstract
The utility model relates to a signal transmission wire, in particular to a cable for transmitting radio-frequency signals and network signals, which aims at improving a signal wire with characteristics of simultaneously transmitting video signals and the network signals and is further applied to overhead wiring. The technical scheme adopted by the utility model includes that the self-supporting network cable combination wire comprises radio-frequency signal wires which are formed by concentrically wrapping an insulating material layer, a shielding layer and a wrapping sheath on outer circumferences of core wires sequentially from inside to outside. The self-supporting network cable combination wire is characterized in that a network wire and a supporting wire are further arranged on the combination wire, and outer sheaths of the supporting wire and the network wire are integrally connected with the wrapping sheath.
Description
Technical field
The utility model relates to a kind of signal transmssion line, specifically is the cable of a kind of transmitting radio frequency signal and network signal.
Background technology
Along with economy, fast development of society, use the sub-district of network and cable TV also more and more.In the network and video signal system that prevails in urban construction or transformation, rf signal line just is used for transmission video signal, and network circuit can only be used to connect network, function singleness.Rf signal line and network circuit normally adopt discrete supporting member to hang respectively, and this has brought inconvenience to laying installation; The operation of laying cable is many, the time is long, and operating expenses is also big, causes the cost of engineering to improve; And surface is adopted in construction mostly, has influenced the clean and tidy of the appearance of the city.For addressing the above problem, the cable that supporting member, continuous suspender belt and cable are connected as a body appears at present, though this brings convenience to laying installation, making bothers, consumptive material is many.
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 the characteristics of transmission video signal, network signal simultaneously; But also be applicable to built on stilts wiring.
The technical solution adopted in the utility model is: self-bearing type network 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 also being provided with on this assemble line a grid line and a supporting-line, the crust of supporting-line and grid line and described foreskin are connected as a single entity.
Described rf signal line, grid line and supporting-line are arranged in parallel side by side.
The core of described supporting-line is a steel wire.
The self-bearing type network cable assemble line that the utility model provides fuses rf signal line, grid line and supporting-line, only needs built on stilts pipeline when mounted, reduces workload widely, and installment work efficient significantly improves.And this cable can own load-bearing, built on stiltsly need not to be provided with in addition the steel strand wire that load-bearing is used when being provided with, and has greatly made things convenient for the wiring installment work; In addition, this cable can be on equipment once the property moulding pull out, the foreskin of whole cable forms an integral body, interconnects close and firm, 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
As seen from the figure: this self-bearing type network cable assemble line, included rf signal line 1 is identical with the structure of existing conventional rf signal line, is coated with one heart successively insulation material layer, screen (generally adopting aluminium foil to add woven wire) and foreskin in the periphery of heart yearn (generally being copper core) 1; The core 4 usefulness metal materials (generally selecting steel wire for use) that also are provided with grid line 2 and supporting-line 3. these supporting-lines on the described rf signal line are successively made, and the crust of supporting-line and grid line and described foreskin are connected as a single entity.
As further improvement of the utility model, described rf signal line 1, grid line 2 are arranged in parallel side by side with supporting-line 3; Generally speaking, the axial line of three lines preferably is in same plane.
Foreskin in the utility model and crust are the homogeneity insulating material (being generally the PVC plastics) that fuses; Extrusion molding together on same equipment, thus parallel arranged is together.
Claims (3)
1, self-bearing type network 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, screen and foreskin in the heart yearn periphery, it is characterized in that also being provided with on this assemble line a grid line (2) and a supporting-line (3), the crust of supporting-line and grid line and described foreskin are connected as a single entity.
2, self-bearing type network cable assemble line according to claim 1 is characterized in that described rf signal line (1), grid line (2) are arranged in parallel side by side with supporting-line (3).
3, self-bearing type network cable assemble line according to claim 1 and 2, the core that it is characterized in that described supporting-line (3) is a steel wire.
