Abstract
The utility model relates to a shielded twisted pair with a load-bearing structure, and aims at solving the technical problem that the twisted pair is applicable to overhead wiring, and can reduce installation workload and improve the installation work efficiency. The adopted technical scheme is as follows: the self-supporting shielded twisted pair comprises an insulated jacket, a shield layer in the insulated jacket, a plastic film layer in the shield layer, and four pairs of twisted pairs in the plastic film layer; the self-supporting shielded twisted pair is characterized in that the insulated jacket is provided with a supporting line side by side; the jacket of the supporting line and the insulated jacket are connected into a whole; a grounding line is arranged between the shield layer and the plastic film layer; the insulated jacket and the supporting line are arranged in parallel; and a core of the supporting line is a single wire or a wire cable stranded by a plurality of wires.
Description
Technical field
The utility model relates to a kind of Shielded Twisted Pair, especially has the Shielded Twisted Pair of load-carrying members.
Background technology
Along with economy, fast development of society, electronic computer is popularized rapidly China, and the applications of computer network is accepted by increasing people and used.The every aspect of people's life has been goed deep in network office, web page browsing, mail transmission/reception, information exchange etc., the applications of computer network.Utilizing twisted-pair feeder to carry out the signal transmission, is the effective and important mode that computer is connected with external network.Existing unshielded twisted pair has had load-carrying members, be highly suitable for built on stilts wiring and install, but existing Shielded Twisted Pair does not but have load-carrying members, when built on stilts wiring, be subjected to action of gravity and sagging deformation, cause intensity decreases and change inside turning round line structure, influenced signal transmission rate.
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 Shielded Twisted Pair is provided, and this twisted-pair feeder should be applicable to built on stilts wiring, can reduce installation workload, improves installment work efficient.
The technical solution adopted in the utility model is: the self-bearing type Shielded Twisted Pair comprises the screen of insulating sleeve, insulating sleeve inside, the plastic membranous layer of screen inside, four pairs of twisted-pair feeders of plastic membranous layer inside; It is characterized in that also being arranged side by side on this insulating sleeve a supporting-line, the sheath and the insulating sleeve of this supporting-line are connected as a single entity; Be provided with earth connection between described screen and the plastic membranous layer again.
Described insulating sleeve and supporting-line are arranged in parallel.
The core of described supporting-line is individual wire or the many stranded steel cables that form of steel wire.
Because the self-bearing type Shielded Twisted Pair that the utility model provides, when built on stilts wiring was installed, the supporting-line that utilizes band steel wire or steel cable was as supporting part, and intensity is very much not yielding.Thereby installation workload reduces greatly, and built on stilts part-structure is stable, has vast market prospect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As seen from the figure: the self-bearing type Shielded Twisted Pair comprises supporting-line and Shielded Twisted Pair; The core 5 usefulness metal materials of described supporting-line (generally selecting individual wire or the many stranded steel cables that form of steel wire for use) are made, and wrap up with insulating sleeve 6; Described Shielded Twisted Pair is identical with the structure of existing Shielded Twisted Pair, is made of eight holding wires 1 in insulating sleeve 4, screen 3, plastic membranous layer 2 and the plastic membranous layer successively from outside to inside; Also be laid with an earth connection 7 between screen 3 and the plastic membranous layer 2; Every holding wire is formed by insulation sheath with by the copper conductor of its parcel; Per two holding wires constitute a pair of holding wire, and twist together mutually by certain density; Eight holding wires constitute four pairs of twisted-pair feeders altogether; The insulating sleeve 6 of supporting-line and the insulating sleeve 2 of twisted-pair feeder are connected as a single entity, once property injection mo(u)lding simultaneously on equipment in the production process.
As further improvement of the utility model, described supporting-line and insulating sleeve are arranged in parallel side by side.
