Description
Technical field
The present invention relates to a kind of butterfly lead-in cable, and in particular to one kind is parallel to lay formula butterfly lead-in cable.
Background technology
With greatly developing for internet, substantial amounts of broadband application promotes people's more bandwidth of needs.At present, introducing
Butterfly lead-in cable can provide bigger bandwidth.But, butterfly lead-in cable is with the raising of transmission frequency, high-frequency symmetrical electricity
Cable ring-down is increasingly apparent；And electric field and magnetic field are open, this open alternating electromagnetic field certainly will be neighbouring
Symmetrical circuit in produce induced potential, here it is cross-talk, and frequency cross-talk higher is more serious.Thus, except return
Road decay is outer, and the cross-talk between high-frequency symmetrical loop is also the key factor for limiting transmission range.Therefore, in manufacture high-frequency symmetrical electricity
During cable, low decay is not only reached, also need to monitor cross-talk index, also need to carry out crosstalk balancing when mounted, it is whole to ensure
The cross-talk of circuit and whole noise meet the requirement of international standard.
The content of the invention
The purpose of the present invention is achieved through the following technical solutions, it is a kind of it is parallel lay formula butterfly lead-in cable, including
Conductor, insulating barrier, reinforcer, screen layer, the oversheath in butterfly-like section, gasket for packing and identification vitta, the insulating barrier are used
The three-layer co-extruded physical foam insulation of pressure injection nitrogen high so that butterfly lead-in cable has low decay, low cost, light weight it is excellent
Point；Conductor is provided with the insulating barrier, insulating barrier outer cladding screen layer, screen layer outer layer places filling longitudinally along the cable
Rope, screen layer is arranged on inside oversheath, and gasket for packing is arranged between screen layer and oversheath so that butterfly lead-in cable entirety
Intensity is high, left and right in oversheath to be symmetrically embedded with reinforcer, it is ensured that the stretching resistance and anti-side pressure of cable, and oversheath cross section is thick
Being respectively provided on two sides with up and down in the middle of degree direction can recognize positive and negative and increasing along what the butterfly lead-in cable length direction extended
" V " type groove of large surface frictional force, identification vitta is embedded in the downside " V " of oversheath between type groove and cable, and with cable integrally
Shaping.
Further, the external diameter of the insulating barrier is 1.35mm.
Further, the core number of the conductor is 2 cores.
Further, the conductor is anaerobic copper conductor, it is ensured that the high-purity of transmission medium, high conductivity.
Further, the reinforcer is phosphating steel wire or non-metallic rods, and preferred non-metallic rods can rise in outdoor application
To the safety requirements to thunderbolt and forceful electric power environment.
Further, the screen layer is aluminium foil.
Further, the oversheath is butterfly-like square-section.
Further, the oversheath is low smoke and zero halogen oversheath so that cable material is in fire-retardant, ageing-resistant and UV resistant
And other irradiation behaviours are greatly improved, so as to improve the security performance of cable, extend the service life of cable, it is to avoid to cable
Infringement.
Further, the gasket for packing is polyester rope, carefully, soft, and lightweight, elasticity is good.
The advantage of the invention is that having low decay, the visual performance of positive and negative is recognized, increase the tactile work(of mantle friction
Can, easy stripping, external diameter is small, and light weight is super soft, low cost, good stretching resistance and compressive resistance, disclosure satisfy that and flies straddle type in 50 meters
Drawing sets, and enhances the transmission rate of data, relaxes the application conditions to environment；And simple structure, reasonable in design, construction is just
Profit, greatlys save and lays space, is widely used in indoor and outdoor and lays to use.
Brief description of the drawings
By reading the detailed description of hereafter preferred embodiment, various other advantages and benefit is common for this area
Technical staff will be clear understanding.Accompanying drawing is only used for showing the purpose of preferred embodiment, and is not considered as to the present invention
Limitation.And in whole accompanying drawing, identical part is denoted by the same reference numerals.In the accompanying drawings：
The parallel structural representation for laying formula butterfly lead-in cable of Fig. 1 present invention.
Specific embodiment
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in accompanying drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.Conversely, there is provided these implementation methods are able to be best understood from the disclosure, and can be by this public affairs
The scope opened it is complete convey to those skilled in the art.
According to the embodiment of the present invention, propose it is a kind of it is parallel lays formula butterfly lead-in cable, see Fig. 1, including conductor 1,
Insulating barrier 2, reinforcer 3, screen layer 4, the oversheath 5 in butterfly-like section, gasket for packing 6 and identification vitta 8；Screen layer (aluminium foil) 4
A pair of symmetrical transmission cables are internally provided with, the balanced cable is by conductor (anaerobic copper conductor) 1 outer cladding pressure injection nitrogen three high
The insulating barrier 2 of the physical blowing of layer co-extrusion, the outer layer of screen layer 4 places gasket for packing (polyester rope) 6, screen layer longitudinally along the cable
4 are arranged on inside oversheath (the low smoke and zero halogen oversheath of butterfly-like square-section) 5, and gasket for packing 6 is arranged on screen layer 4 with outer shield
It is left and right in oversheath 5 to be symmetrically embedded with reinforcer (non-metallic rods) 3 between set 5, it is upper in the middle of the tranverse sectional thickness direction of oversheath 5
Under be respectively provided on two sides with along the butterfly lead-in cable length direction extend " V " type groove 7 with vision and tactile, " V " type
The ratio between depth and width of groove about 1:1, the top of downside " V " type groove 7 of the identification insertion oversheath 5 of vitta 8, with cable integrally
Shaping.
This specific embodiment is in order to preferably protect anaerobic copper conductor, and it is exhausted that outside has coated three-layer co-extruded physical blowing
Edge layer, after stripping, can directly register one's residence installation, and cause that the parallel formula butterfly lead-in cable product that lays has a low decay, it is low into
This, the advantage of light weight；Polyester rope is longitudinally filled between screen layer and oversheath so that parallel to lay formula butterfly lead-in cable product
Product bulk strength is high, and elasticity is good, lightweight, and two symmetrical non-metallic rods reinforcers are embedded in outer protective sleeve, it is ensured that electricity
The stretching resistance and compressive resistance of cable, disclosure satisfy that fly in 50 meters that straddle type is drawn sets and can be played in outdoor application to thunderbolt and strong
The safety requirements of electrical environment, while butterfly-like square-section low smoke and zero halogen oversheath so that parallel to lay formula butterfly lead-in cable
Product is greatly improved in fire-retardant, ageing-resistant and UV resistant and other irradiation behaviours, so as to improve the security performance of cable, is extended
The service life of cable, it is to avoid infringement to cable, and " V " type groove has identification positive and negative in the presence of vitta is recognized
Visual performance, and with the feeling function of increase mantle friction, easy stripping, while also save raw material, foil shielding layer
With excellent shielding properties.
To sum up, this specific embodiment external diameter is small, lightweight, low decay, tension, resistance to compression, easy stripping, and strong security etc. is excellent
