With reference to embodiment come the present invention will be described in detail create.
A kind of high-performance data cable, as shown in Figure 1, include cable core, be coated with successively on the outside of cable core cable core band 1, Composite sheath 2, armor 3 and oversheath 4;The cable core includes four lines pair 6 on center framework 5 and center framework;Institute It includes support ontology 7 to state center framework, and the outer rim of the support ontology is provided along its length four U-type grooves 8, each described U-shaped Slot is uniformly arranged centered on supporting body central line;Each line is to being respectively placed in one of U-type groove;The line pair Including two mutually twisted insulated single wires 9, it is coated with woven shield 10 and inner sheath 11 successively on the outside of the two;The volume It knits and is equipped with an at least aerial drainage line 12 between shielded layer and inner sheath.Capsicum can also be filled between oversheath and armor Element, being capable of effective protection against rodents.In addition, in an alternative embodiment, one can also be added between cable core band and composite sheath Layer shielded layer, improves shield effectiveness.In general, insulated single wire includes the insulating layer 14 of internal copper conductor 13 and its outside cladding.
This high-performance data cable is provided with aerial drainage line, and aerial drainage line is arranged between inner sheath and woven shield, It can ensure that woven shield after laying and in being used for a long time, remains excellent interference free performance, meets bonding and want It asks.
Above-mentioned composite sheath generally use single side aluminium foil longitudinal tubing, and extrude what one layer of sheath was made outside it. In order to ensure that the roundness and shielding properties of cable, the thickness control of single side aluminium foil should be greater than 0.05mm or more, single side aluminium foil is vertical Packet seam crossing is bonded using heat-seal adhesive.
Above-mentioned insulating layer uses skin-bubble-skin physical blowing structure of co-extrusion.Insulating layer is three-layer co-extruded skin-bubble-skin object Manage foamed insulation.Insulating resistance of cable can be improved, reduce the sending allowance of cable, reduce the mutual capacitance of cable, to significantly The reliability for improving the safety of cable and using.
Above-mentioned armor uses steel plastic band corrugated longitudinal wrapping armor layer, it has shield effectiveness good, and steel plastic band dosage is small, production Efficient, manufacturing cost is low.And composite steel-plastic belt has ripple struction, structural strength is high, is unlikely to deform, and cable has higher anti- Tensile strength and bending property.
Above-mentioned woven shield uses copper wire or tinned copper wire woven shield, and the shielding properties to ensure cable is excellent, Interfering with each other between reduction cable core, copper wire or tinned copper wire diameter used by the woven shield answer >=0.1mm, and weave Tight ness rating answers >=85%.
Above-mentioned support body cross-section structure in disk form, for line to being equivalent in embedded U-type groove, structural stability is high, right Title property is good.When overcoming using cross shape skeleton, line is easy to cause random line, the impedance of cable, declines at cross-talk to unstable Subtract etc. between indexs are undesirable and each core wire and interfere with each other the defects of serious, effectively increases properties of product.
Center framework uses, and there is low-density polyethylene material flexible to be made, in stranding, first fixing line pair and cross Then the position of skeleton makes 4 pairs of twisted-pair feeders to dividing in 4 U-type grooves to embedded center framework, while twisting is molded;When twisted wire, Center framework with U-type groove can ensure line to will not up and down be shaken in U-type groove, and cable final product quality obtains can The guarantee leaned on, this cable have structural stability high, and the good feature of symmetry can effectively improve impedance, cross-talk, the decaying of cable Etc. indexs, reduce and the performances such as interfere with each other between core wire.
Above-mentioned line is more than 75mm to bending radius.Center framework with U-type groove is usually softer and tiny, makes finished cable Also there is good flexibility, facilitate cable wiring manufacture.
When making this cable:First the insulated single wire of two different colours is twisted, line pair is made, is then being twisted Line externally select copper wire or tinned copper wire and using weaving weave one layer of woven shield, later outside woven shield It is suitable to put an at least aerial drainage line and extrude one layer of inner sheath one-pass molding.Then use machine for making cable high-speedly by produced 4 lines To being separately positioned in the U-type groove of preprepared center framework, carry out being twisted into cable core, and coat cable successively outside cable core Core belting layer, composite sheath, armor and oversheath.
It should be noted that since strand pair and stranding are larger to crosstalk effect, when design lines are to pitch, the section of adjacent lines pair Answered away from difference as big as possible, adjacent and similar line should not be at low integral multiple relation to pitch.It is high performance in order to reach data cable It is required that, it is necessary to back twist technique is used, for back twist rate general control within 30%, maximum is not to be exceeded 50%.It should be noted that If laying up pitch is too big, the loss of cable bend stress back echo and characteristic impedance will be affected;If pitch is too small, it is easy to make The capacitance of cable, decaying become larger.Therefore, in entire cabling process, the extension tension of line pair should be maintained within ± 10%, line To bending radius should be greater than 75mm, to ensure that cable core structure is stablized, performance will not deteriorate.
This cable breaches technical limitation, and the center framework with U-type groove is provided in cable core, can be ensured When twisted wire, any line is high with structural stability to will not all be shaken up and down in U-type groove, the good feature of symmetry, together When, just because of using back twist technique, back twist rate to control within 30%, in addition to the control of the extension tension of line pair, effectively The indexs such as impedance, cross-talk, the decaying of cable are improved, reduces and the performances such as interferes with each other between each line pair, realize high performance want It asks.
Due to using copper wire or tinned copper wire woven shield individually shielded to carrying out to each line, the shielding of cable can be improved Performance and mechanical and physical performance, further splicing thread signal between interfere with each other.Meanwhile cable core packet is coated on the outside of cable core Band, composite sheath, armor and oversheath can be effectively improved cable toughness deficiency during alternating bending, laying installation, screen The problems such as layer is easily broken is covered, cable has the performances such as superior heatproof, moisture-proof, high safety and reliability.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention Protection domain within.
