Background technology
Along with economic, social fast development, use the community of network and office building also more and more, the network cable of using also improves gradually.Network cable, i.e. Network Cable network connection, is the medium that is connected to another one network equipment transmission of information from a network equipment, is the basic building block of network.Cable is as the carrier of signal transmission, also in continuous renewal, to meet the demand of transmission.Under normal conditions, a typical local area network (LAN) is generally can not carry out interconnection network equipment with multiple different types of netting twine.In catenet or wide area network for dissimilar network is linked together and will use different types of netting twine.In the netting twine of numerous kinds, specifically use any netting twine will be according to topology of networks, network configuration standard and transmission speed are selected.At present data network cable can with communication media mainly contain Four types: unshielded twisted pair, Shielded Twisted Pair, coaxial cable and optical cable; Bad for environmental condition, in the situations such as low temperature, greasy dirt, acid and alkali corrosion, often there is the phenomenons such as cold cracking, high temperature deformation, signal transmission are fuzzy, rotten, hardening in existing network cable, and because spacing between each cable is very near, there is crosstalk phenomenon, signal bandwidth and speed are affected.
For example; Chinese patent literature discloses a kind of transparent screen wire [application number: 200720127206.6]; comprise transparent insulation cover, internal portioning layer, twisted-pair feeder and protective layer; it is characterized in that: the inside of transparent insulation cover is provided with the plastics internal portioning layer of right-angled intersection shape; netting twine inside is evenly divided into four parts by internal portioning layer; every part is furnished with two twisted-pair feeders, between internal portioning layer and transparent insulation cover, is provided with insulating protective layer.
Although such scheme has solved the problem that prior art exists to a certain extent, still exists design reasonable not, corrosion stability is poor, and shield effectiveness is poor, and result of use is undesirable, cannot meet people's user demand.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, meets the shielded twisted pair of people's user demand.
For achieving the above object, the utility model has adopted following technical proposal: this shielded twisted pair, comprise the cable cover of being made by insulating material, it is characterized in that, in described cable cover, be equipped with four groups of twisted-pair feeders that are respectively used to transmit variety classes signal, each group twisted-pair feeder comprises respectively two mutual stranded wires, each wire comprises respectively core and is coated on the core protective layer of being made up of insulating material of core periphery, four groups of twisted-pair feeders are mutually stranded, the twisting pitch of described wire is less than the twisting pitch of twisted-pair feeder, be coated with respectively screen in each group twisted-pair feeder periphery, be provided with anti-flaming thermal-insulation layer at cable cover inwall, described anti-flaming thermal-insulation layer is placed on four groups of stranded twisted-pair feeder peripheries mutually.
In above-mentioned shielded twisted pair, four groups of described twisted-pair feeders be located in the elastic layer of being made by elastomeric material and elastic layer banding on four groups of twisted-pair feeders, described anti-flaming thermal-insulation layer is positioned at elastic layer periphery.
In above-mentioned shielded twisted pair, described core is made of copper; Described cable cover and core protective layer are made up of PVC material.
In above-mentioned shielded twisted pair, the contact portion of two core protective layers of each described group twisted-pair feeder is connected as a single entity through hot melt.
In above-mentioned shielded twisted pair, described cable cover inwall build-in has the shielding net of being made up of metallic mesh material.
Compared with prior art, the advantage of this shielded twisted pair is: 1, reasonable in design, simple in structure, meet people's user demand.2, anti-aggressivity is strong, long service life.3, shield effectiveness is good, and transmission stability is strong.
