Description of the drawings
Fig. 1 is the structure chart of a specific embodiment of the invention.
In figure：1st, cable conductor；2nd, insulator；3rd, aluminum-plastic composite membrane；4th, copper mesh；5th, sheath；6th, polyester layer.
Specific embodiment
With reference to Fig. 1, one specific embodiment of the present invention includes cable inner core and the insertion on the outside of cable inner core is washed
The sheath 5 of synthetic fibre layer, cable inner core include cable conductor 1, and 1 outside of cable conductor is enclosed with insulator 2,2 outer side covers of insulator
There is aluminum-plastic composite membrane 3,3 outside of aluminum-plastic composite membrane is enclosed with copper mesh 4, and the inside of sheath 5 sets and is embedded in the terylene in restrictive coating
Layer 6.Cable inner core is coaxial cable inner core or twisted-pair cable inner core.
This programme is that polyester filament braiding is laid within coaxial cable or twisted-pair feeder oversheath and is passed through terylene is long
Silk weaves in embedded sheath to form enhancing of the composite jacket realization to cable.The structure of coaxial cable is：In soft copper is twisted
Conductor or day element line are twisted inner wire, the insulating layer being coated on conductor, are by aluminum-plastic composite membrane cladding and copper wire outside insulating layer
The outer conductor layer of braiding, outer conductor layer are outside the enhancement layer of polyester filament braiding, are then the restrictive coating of cable.Twisted-pair cable
Structure be：Multipair twisted-pair feeder forms cable core, the enhancement layer of the polyester filament braiding directly woven outside cable core or
What the polyester filament woven outside the shielded layer being made of outside cable core cladding aluminum-plastic composite membrane cladding and copper wire woven wove
Enhancement layer is then the restrictive coating of cable.When dacron thread weaves, by appropriate technological design, braiding layer surface is made there are rule
Then a uniformly distributed some holes.In sheathing using plsitive mold, and protective cover material is improved to braiding layer by technological design
Pressure makes protective cover material be pressed into braiding layer, braiding layer is embedded in restrictive coating, so as to form composite jacket.
This programme is by using load-bearing of the polyester filament braiding layer of high-strength flatness (high intensity, flatness are long) type as cable
Element.Since the density of material of polyester filament is far below steel wire, the elevator trailing vision cable enhanced with the art of this patent
The weight change of itself is little, but by rational Technology design, can equally achieve the effect that steel wire reinforcement.
If it is required that braiding layer have higher enhancing performance and also the outer diameter of cable is influenced it is smaller in the case of, can adopt
By the use of aramid fiber as the braided material of enhancement layer.
This programme is not more than the terylene of 6dtex using intensity higher than 10cN/dtex and elongation less than 3%, filament number
Long filament is as braided material.The benefit for selecting flatness long filament is when cable under tension, because the elongation of dacron thread is far below
The elongation (elongation of other cable materials is both greater than 15%) of other cable materials, so enhancement layer takes the lead in bearing cable
Most of pulling force, so as to protect cable.
In braiding, it is ensured that the angle that polyester filament and cable axis are formed is between 25 °~40 °, and preferably angle is at 25 °
Between~30 °.In this angular range, during due to braiding layer under tension its perpendicular to the component of cable axial direction much smaller than parallel
In the component of cable axial direction, so both ensured that braiding layer had the structure of its inside certain holding, and the degree deficiency held tightly
It is had an impact with the structure to its inside, while in turn ensures that braiding layer has the sufficient ability for bearing pulling force.If braiding layer
The structure of its inside is excessively held tightly, then can reduce the signal transmission performance of cable.
In definite dacron thread dosage, should make should be big according to the total pull-off force of the dacron thread obtained by the Strength co-mputation of dacron thread
In 4 times of the dead weight of every 100 meters of cables and no more than 6 times.It so both can guarantee the intensity of cable, and had and be unlikely to because of dacron thread dosage
The excessive but outer diameter of cable increases excessively, also ensures the cost of cable in the reasonable scope.
Due to the not only weight penalty of the steel wire rope dead weight of cable of the cable strengthened with steel wire rope, but also use sheath
Coated cable is expected, so as to add the dosage of protective cover material.And when using this programme, according to calculating, when the pull-off force of dacron thread
When suitable with the aircraft cable of Φ 1.0mm, the weight of dacron thread only has the 11% of steel wire rope weight.Therefore its to cable from
Ghost image rings smaller.
The basic principles, main features and the advantages of the invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
