Abstract
The utility model belongs to the technical field of the cable technique and specifically relates to a six types of network cable of elevator retinue. The laminiform one -tenth heart yearn of extruded insulation around its conductor, per two heart yearns are pressing from both sides a word skeleton and are stranding paired line of formation, and the package is wound to the paired line in reuse polyester area. With four paired line and two mild zinc -plated tensile steel wires word arrangements with the transposition of different pitches, a fan -shaped six types of network cable of elevator retinue is made to whole crowded package elasticity sheath. Since every paired line have a word skeleton isolation and polyester area around package, four paired line mutual isolations, consequently the signal between better, the paired line of the dielectric properties between two conductors of every paired line is crosstalked and is reduced by furthest, makes the signal transmission performance of whole cable outstanding, because the bend radius of cable has been reduced greatly to soft conductor, elasticity sheath and the flat structure of cable, tensile steel wires has been applyed again to the cable both sides, and consequently whole root cable has outstanding flexibility ability and tensile strength.
Description
Technical field
This utility model is related to field of cable technology, especially a kind of elevator trailing six class network cable.
Background technology

Transmission video signal, 4 heart yearns are used for powering for web camera from POE switch.Because lift car is continually in elevator
Moved up and down in hoistway, the elevator trailing cable being therefore connected with car must possess good resist bending performance and tension
Performance.Conventional network cable, such as surpasses five class netting twines, six class netting twines, is used to premises distribution system in the market
Middle level fixation is laid, and lacks enough resist bending and tensile property, is not therefore suitable for being in connection elevator vertical hoistway
The lift car of kinestate.Although also occur in that in the market conductor be the stranded soft netting twines of many copper wires be used for elevator with
Row cable, but the 8 of such cable heart yearn arrangement modes, still based on circular stranding, cause the resist bending performance of cable inadequate
Ideal, and line between SCR more serious, lead to the general network that signal transmission performance is well below same level
Cable.
Content of the invention
In order to overcome the shortcomings of that existing cable can not meet use demand, this utility model provides a kind of elevator trailing
Six class network cables.
This utility model solves its technical problem and be employed technical scheme comprise that：A kind of elevator trailing six class network cable,
Including conductor and insulating barrier, around described conductor, extruded insulation layer forms heart yearn, and two heart yearn pair twists form 1 twisted-pair feeder, core
Be provided with a character skeleton in the middle of line, polyester belt will be stranded to a character skeleton and heart yearn after wrapped up, be provided with outside polyester belt elasticity shield
Set, is provided with tensile steel wire in described flexible sheath.
According to another embodiment of the present utility model, further include, described tensile steel wire is by least 2 zinc-plated thin steel
Silk is stranded to be formed, and the zinc-coated wire that tensile steel wire is 0.20mm by 19 line diameters is stranded to be formed.
According to another embodiment of the present utility model, further include, described conductor is 0.22mm by 7 line diameters
Oxygen-free copper-wire stranded form.
According to another embodiment of the present utility model, further include, a described character skeleton is by Low Density Polyethylene material
Material extrudes and forms, and its thickness is 0.2mm, and width is 2.0mm.
According to another embodiment of the present utility model, further include, described flexible sheath is Lycoperdon polymorphum Vitt, and it is the thinnest up and down
The thickness at place is not less than 0.8, and the thinnest part thickness outside tensile steel wire is not less than 1.5mm, outside integral, flexible sheath
Shape a size of 4.4 × 19.0mm.
The beneficial effects of the utility model are that this elevator trailing six class network cable adopts many copper cash stranded, structure
Softness, is suitable for being frequently bended；Around conductor, extruded insulation layer forms heart yearn, and two heart yearns clip a character skeleton and carry out stranded formation
A piece twisted-pair feeder, then with polyester belt, twisted-pair feeder is carried out wrapped, so makes dielectric properties between two conductors of twisted-pair feeder more
Good；By four with the soft zinc-plated tensile steel wire word order of the stranded twisted-pair feeder of different pitches and two, integrally extrude elasticity
Sheath, makes the elevator trailing six class network cable of a flat；Because four twisted-pair feeders are mutually isolated, therefore between twisted-pair feeder
Signal cross-talk is farthest reduced, and along with every twisted-pair feeder has the isolation of a character skeleton, so that the signal of whole cable is passed
Defeated excellent performance；The squashed structure of cable is conducive to reducing the bending radius of cable；Two tensile steel wire also make cable vertical
During suspension, enough pulling force can be born；By above-mentioned design, this utility model is made to have outstanding resist bending performance
And tensile property, and there is the characteristic of low signal crosstalk, signal transmission performance reaches the standard of six class non-shielding netting wires.
