Technical field
The utility model relates to high-power low loss cable.
Background technology
Modern communications equipment is had higher requirement to the efficiency of transmission of telecommunication cable, as requires the physical dimension of cable as much as possible little; Have less bending radius; Lay so that install, require telecommunication cable to have high through-put power again simultaneously, with the stronger radio signal of emission.
The size of cable transmission power, the height of efficiency of transmission is that the factors such as temperature resistant grade by the physical dimension of cable, transmission attenuation, insulating material determine.The through-put power of telecommunication cable and the physical dimension of cable are a pair of paradox, and people utilize the method for the physical dimension that improves cable to promote the through-put power of cable usually.
The extent of deterioration of the through-put power the when pad value of cable has shown cable work, the pad value of cable is big more, shows that then the extent of deterioration of signal in the cable transmission process is big more, and the efficiency of transmission of cable is also poor more.In order to improve the efficiency of transmission of cable; Always hope that cable has alap pad value; But the cable of the low decay physical dimension through improving cable and the form of using the tubular-type outer conductor is often realized; The cable product of large scale tubular-type outer conductor often causes manufacturing cost high, and is high to the requirement of environment for use, shortcomings such as bending property difference.
The temperature resistant grade of cable material has also limited the extent of the through-put power of telecommunication cable, when the through-put power on the telecommunication cable is too big, can produce the cable over-heat inside, causes mechanical failure, makes descend the useful life of cable.
The utility model content
The purpose of the utility model is, a kind of high-power low loss cable is provided, to solve the existing technical problem that cable dimension is excessive, loss is high that satisfies through-put power.
The technical scheme of the utility model is following:
A kind of high-power low loss cable comprises the inner wire that is positioned at the center and is positioned at outermost sheath; Also be provided with outer conductor between said inner wire and the sheath, be provided with insulating barrier between outer conductor and the inner wire.
Said outer conductor comprises the silver-gilt copper wire braid.
Said silver-gilt copper wire braid is a double-layer structure.
Be provided with aluminium strip between said silver-gilt copper wire braid and the said sheath.
Said insulating barrier is non-expanded polytetrafluoroethyl(ne film and the compound wrapped structure of expansion type polytetrafluoroethylene film.
The high-power low loss cable outer conductor of the utility model adopts silver-gilt copper wire to replace original copper strips, under same power, can original outside diameter of cable be dwindled about 50%.Less physical dimension makes communication equipment promptly to install and remove, transportation.Construction of cable size has directly determined the bending radius of cable, has also directly had influence on the overall structure size of communication equipment.The insulating barrier that compound insulation is wrapped; Its structure is wrapped jointly and is formed by the higher F4 of compressive resistance (polytetrafluoroethylene) film and lower FC (expansion type polytetrafluoroethylene) film of dielectric constant; The peak power of bearing has reached 45KW; And the cable of employing common PE (polyethylene) material, under measure-alike prerequisite, its peak power that can bear but has only 25KW.
Description of drawings
Fig. 1 is the structural representation of the high-power low loss cable embodiment of the utility model.
Embodiment
Further describe the concrete technical scheme of the utility model below in conjunction with accompanying drawing and embodiment,, and do not constitute restriction its right so that those skilled in the art understands the utility model.
Modern communications equipment is had higher requirement to the efficiency of transmission of telecommunication cable, as requires the physical dimension of cable as much as possible little; Have less bending radius; Lay so that install, require telecommunication cable to have high through-put power again simultaneously, with the stronger radio signal of emission.The high-power low loss cable of the utility model dwindles construction of cable size through the improvement of structure, can reach the little and big grade of the through-put power requirement of pad value simultaneously, is applicable to the military communication field.
The high-power low loss cable of the utility model comprises the inner wire that is positioned at the center and is positioned at outermost sheath; Also be provided with outer conductor between said inner wire and the sheath, be provided with insulating barrier between outer conductor and the inner wire.
Particularly, as shown in Figure 1, the high-power low loss cable of the utility model comprises the inner wire 1 that is positioned at the center and is positioned at outermost sheath 4; Also be provided with outer conductor 2 between said inner wire 1 and the sheath 4, be provided with insulating barrier 3 between outer conductor 2 and the inner wire 1.Said outer conductor 2 comprises two-layer silver-gilt copper wire braid 21,22, and the aluminium strip 23 between said silver-gilt copper wire braid and the said sheath 4.Said insulating barrier 3 is non-expanded polytetrafluoroethyl(ne film 31 and expansion type polytetrafluoroethylene film 32 compound wrapped structures.
Insulating barrier 3 in the utility model is the important component parts in the construction of cable, and the selection of the insulating material of high-power, low loss cable will be considered following several aspect emphatically:
1) lower dielectric constant: the dielectric constant of cable is low, and then the transmission attenuation of cable is little, and the efficiency of transmission of corresponding cable is just high, and through-put power is big.At present, the insulating material of high power cable is confined to PE (polyethylene) usually, and the dielectric constant of PE is 2.4, and the dielectric constant of FC material can reach 1.35.
2) temperature resistant grade: the size of the average power that cable bore is decided by the temperature resistant grade of cable, and the temperature resistant grade of cable is to be determined by insulating material basically, and the temperature resistant grade of material is high, and the through-put power that cable can bear is big.The temperature resistant grade of PE (polyethylene) material commonly used has only+and 80 ℃, and the temperature resistant grade of FC material can reach+200 ℃, and this is to improving the through-put power capacity of cable, and the stability that improves product all plays a part bigger, is a qualitative leap.
Cable adopts this material of FC as insulating barrier, makes this cable under the prerequisite of small construction size, has less dielectric constant, higher temperature resistant grade, less transmission attenuation, higher through-put power.
What the outer conductor 2 in the utility model adopted is the Weaving type outer conductor.
High power cable is in order to have less pad value, lower standing-wave ratio, and general multiselect use the tubular-type outer conductor, with the structural stability of raising cable, uniformity.The tubular-type outer conductor has various ways, and is in the majority with bellows outer conductor form, and like the FC645 cable of U.S. FLEXCO company, what its outer conductor adopted is exactly the wrinkle copper pipe.Characteristics such as the cable of this structure has Stability Analysis of Structures, and the standing wave performance is good.But in the occasion that usage space is had high requirement, like emission feeder line of the wire jumper in the rack, microminiature radar etc., there is certain deficiency in the bending property of this product.In order to satisfy the requirement of modern electronic equipment to the flexibility of cable, cable adopts the Weaving type outer conductor.
The Weaving type outer conductor has bending property, is convenient to install and remove fast, can alternating bending.But the version of braid is with respect to the bellows structure, and what uniformity will be relative is weaker.To this, we have descended the very big time from weaving, the technical staff of associating cable machinery manufacturing enterprise; Through continuous research of technique; Successfully developed special-purpose braiding machine, the uniformity of the SFCF-50-23 cable of being produced almost can compare favourably with the tubular-type outer conductor, and voltage standing wave ratio is consistent with FC645 basically; Under the frequency of 3Ghz, voltage standing wave ratio has been accomplished below 1.2 equally.
Above-described embodiment is merely the technological thought and the characteristics of explanation the utility model; Its purpose is the content that makes those skilled in the art can understand the utility model and implements according to this; Can not limit the protection range of the utility model according to this; The equalization of promptly being done with the spirit that the utility model was disclosed changes or derives, and must be encompassed in the protection range of the utility model.
