Description
Technical field
The utility model belongs to communication cable technical field, more particularly to a kind of high intensity cable for digital communication.
Background technology
With the high speed development of modern communicationses cause, the use of cable for digital communication is more and more also to become increasingly complex, such as
Indoors under carpet, in wall gutter groove and outdoor adverse circumstances, cable is formed unavoidably and tramples, extrude, stretch, hit and
Dragging during construction etc., this external influence damage to the cored wire inside cable and core structure, and then influence data
Transmittability, this requires that data cable has preferable resistance to compression, tensile strength, and a preferable flexibility, and current number
Word communication cable is unable to reach requirements above.Need a kind of high intensity cable for digital communication.
Utility model content
The purpose of this utility model is to solve problem described in background technology, there is provided a kind of high intensity digital communication electricity
Cable, for the utility model by the design of unique texture, cable has preferable anti-tensile, compressive property, while has preferably soft
Soft energy, meets the requirement of digital communication.Its technical scheme is：
High intensity cable for digital communication includes cored wire group 1, filler 2, belting layer 3, vertical covering 4, woven shield 5, interior
Sheath 6, armor 7 and outer jacket 8,
The wire stranding that cored wire group 1 is made up of 2 solid copper conductor cladding polyethylene layers is formed, and cored wire group is twisted
Pitch is 9~20mm, again with belting layer 3 around the cable core for being bundled into circular cross section after 1~8 pair of cored wire group 1 is twisted, in twisted core
Filled up in gap between line group 1 and belting layer 3 and fill filler 2, outside cable core, coat vertical covering 4, braiding successively from inside to outside
Screen layer 5, sheath 6, armor 7 and outer jacket 8 form high intensity cable for digital communication；
The filler 2 is aramid fiber；
The material of the belting layer 3 is polyester belt；
Individual layer plastic-aluminum combined paper tinsel of the vertical covering 4 for vertical bag on belting layer 3；
The woven shield 5 is woven on vertical covering 4 with tinned copper wire and formed；
The sheath 6 is the low smoke and zero halogen soft type polyvinyl chloride being extruded on woven shield 5；
The armor 7 is the armouring that serpentine steel band is coated on spiral interlocking sheathed structure technique on sheath 6
Layer；
The outer jacket 8 is extruded on armor 7, and outer jacket 8 is polyurethane elastomer sheathing+talcum powder+cross-linking radiation
The compound outer jacket that pvc sheath is formed, i.e. the internal layer of outer jacket 8 is polyurethane elastomer sheathing, and outer layer is cross-linking radiation
Pvc sheath, central filler talcum powder.
The utility model realizes the high-intensity performance of cable from following several respects：
1. using the aramid fiber of filling, cored wire on the one hand can be protected not to be stressed destructions, on the other hand due to aramid fiber fibre
Dimension higher intensity and flexibility, further improve cable tensile strain intensity；
It is 2. mutual with preferable anti-tensile, compression strength, and serpentine with the armor of serpentine steel spiral interlocking armouring
Lock construction has good pliability, does not influence the bending of cable, furthermore steel material can play shield effectiveness, improves the anti-of cable
Electromagnetic interference capability；
3. the compound outer jacket formed using polyurethane elastomer sheathing+talcum powder+irradiation cross-linked polyvinyl chloride sheath, interior
The polyurethane elastomer of layer can play absorption pressure, protection internal structure effect, the irradiation cross-linked polyvinyl chloride of outer layer have compared with
Strong fire resistance rating and mechanical performance, adapts to more severe outdoor environment.
The utility model material therefor does not contain the harmful substances such as the more bromides of lead, cadmium, meets green requirement.
The beneficial effects of the utility model are, on the basis of realizing high speed data transfer, have higher anti-tensile, resistance to compression and compared with
Good softness.The sandwich construction of cable ensure that cable core structure is stable, in work progress, will not destroy the cored wire of cable
And influence the performance of data transfer.
The utility model is applied to easily trampled, extruded and without the network layout of the protective environments such as pipeline, wire casing.
