Abstract
The invention relates to a coaxial bunched cable for 3G (third generation) communication. The coaxial bunched cable comprises a physical foaming polyethylene insulating layer, an aluminum composite tape outer conductor, a tinned copper braid shielding layer and a photothermal-resistant polyethylene protective sheath which are arranged on the exterior of an inner wire of a copper-clad aluminium wire in sequence and also comprises a chemical foaming polyethylene padding core, a non-woven fabric inner protective layer, a cotton yarn tearing rope and a photothermal-resistant polyethylene outer protective sheath, wherein chemical foaming polyethylene padding cores are respectively arranged among four coaxial cables and are twisted together, the exterior of the cables are provided with the non-woven fabric inner protective layer and the photothermal-resistant polyethylene outer protective sheath, and the cotton yarn tearing rope is arranged between the non-woven fabric inner protective layer and the photothermal-resistant polyethylene outer protective sheath. The coaxial bunched cable provided by the invention has the characteristics of stable electric performance index, compact structure and simplicity and convenience in installation and construction, thus the electric performance index of the cable can be ensured not to change along with the change of installation places.
Description
Technical field
Patent of the present invention relates to a kind of 3G communication and uses coaxial bunched cable, is widely used in systems such as 3G mobile communication, microwave measurement, space flight and aviation, navigation.
Background technology
At present China mobile communication, broadcasting in building used 5D-FB physical foam insulation coaxial cable more; In transmission signals, often single coaxial cable can not satisfy instructions for use, needs four-core and following coaxial cable; Need to lay a lot of times; Construction and installation are very inconvenient, and structure is compact inadequately, and it is bigger to take up room.
Summary of the invention
In view of the deficiency that prior art exists, the invention provides a kind of 3G communication and use coaxial bunched cable.
The present invention is for realizing above-mentioned purpose.The technical scheme of being taked is: coaxial bunched cable is used in a kind of 3G communication; It is characterized in that: be included in the coaxial cable that the copper-clad aluminum conductor inside conductor is provided with one deck physically foamed pe insulation layer, aluminium-plastic tape outer conductor, tinned wird woven shield, fast light hot polymerization ethene sheath formation outward successively; Comprise that also chemical blowing polyethylene filled core, nonwoven fabrics sheath, cotton yarn tear rope, fast light hot polymerization ethene oversheath; A chemical blowing polyethylene filled core is set respectively between four said coaxial cables to twist together; Outside it, be provided with layer of non-woven fabric sheath, fast light hot polymerization ethene oversheath successively, vertically between nonwoven fabrics sheath and fast light hot polymerization ethene oversheath put a cotton yarn and tear rope.
Characteristics of the present invention are: this cable has had that electricity function index is stable, installation is easy, the characteristics of compact conformation.The electricity function index that has guaranteed cable can not change along with the variation that occasion is installed.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Shown in Fig. 1; Coaxial bunched cable is used in a kind of 3G communication; Be included in copper-clad aluminum conductor inside conductor 1-1 and be provided with the coaxial cable 1 that one deck physically foamed pe insulation layer 1-2, aluminium-plastic tape outer conductor 1-3, tinned wird woven shield 1-4, fast light hot polymerization ethene sheath 1-5 constitute outward successively; Also comprise chemical blowing polyethylene filled core 2, nonwoven fabrics sheath 3, cotton yarn tear the rope 4, fast light hot polymerization ethene oversheath 5; A chemical blowing polyethylene filled core 2 is set respectively between four said coaxial cables 1 to twist together; Outside it, be provided with layer of non-woven fabric sheath 3, fast light hot polymerization ethene oversheath 5 successively, vertically between nonwoven fabrics sheath 3 and fast light hot polymerization ethene oversheath 5 put a cotton yarn and tear rope 4.
Its manufacturing approach comprises the following steps:
1. physically foamed pe insulation layer: skin-bubble-Pi Shi is adopted in insulation, i.e. endodermis employing low density polyethylene (LDPE); Low density polyethylene (LDPE), high density polyethylene (HDPE) and nucleator composite material is in proportion adopted in foaming layer, and injects nitrogen dioxide gas, increases foam degrees, is that foam degrees is brought up to 78%-81% by about 70% of other products; Exodermis adopts high density polyethylene (HDPE).The insulating barrier external diameter is 4.8mm.
2. aluminium-plastic tape outer conductor and tinned wird woven shield: what outer conductor used is that width is 18mm, and thickness is the aluminium-plastic tape of 0.05mm, adopts the form of vertical bag to be coated on outside the insulation; Screen is that 9 strands of 0.15mm tinned wirds use the metal knitted machine of 16 ingots, is woven on the outer conductor with the pitch of 40mm.
3. fast light hot polymerization ethene sheath: adopt fast light hot polymerization vinyl material to be extruded on the screen through the sheath extruder, make cable have good weather, the sheath external diameter is 5.7mm.Stamp numeral simultaneously in the outside of sheath to show differentiation.
4. chemical blowing polyethylene filled core: adopt the chemical blowing polythene material, extrude the filled core that external diameter is 3.1mm through extruder.The adding of filled core has guaranteed the rounding property behind the cable twisting, is that bunched cable can also keep good electric property in the environment of bending.Simultaneously, the filled core density of this material is less, and is very little to the weight influence of cable.
5. stranded cable and wrapped nonwoven fabrics sheath: warping winch is regular twists together twisting pitch 550mm through 18 dishes with four 5D-FB coaxial cables and five chemical blowing polyethylene filled cores.Stranded back is wide with 45mm with machine, and the nonwoven fabrics that 0.15mm is thick is wrapped outside stranded unit, has guaranteed the compactedness of structure, also guarantees the consistency of 5D-FB coaxial cable performance.
6. fast light hot polymerization ethene oversheath: adopt fast light hot polymerization vinyl material outside the sheath extruder is extruded in the nonwoven fabrics sheath; Make cable have good weather; At random before head along advancing the cotton yarn of an external diameter about 0.7mm as tear line, the oversheath external diameter is 21.8mm.
