Description
Technical field
The present invention relates to cables, and in particular to a kind of elevator is vertically accompanied cable for digital communication.
Background technique
Within elevator, due to there are various interference sources, the wireless access system of video monitoring or the network coverage, with elevator
Operation, signal can be extremely unstable.Therefore, most reliable access still obtains by the way of wired.
However, common data cable is unable to satisfy.Because high-frequency digital signal transmits, consistent to the structure of medium
Property and stability are more sensitive, and the structure of this relationship knife cable designs and manufactures technique itself.
For the scene of fixed wiring, cable is just no longer moved once installation.Therefore, construction of cable when factory is not
It can change because of moving for product.Multiple fixed safeguard measure when wiring, also effectively can avoid external force to cable
Effect, and then deformation due to guarantee that cable will not act at the external force on recurring structure.
However, cable itself has to accompany with elevator lifting when cable application is when on the elevator of vertical lift.At this
In a long-term duplicate motion process, since cable follows the bending deformation caused by elevator lifting repeatedly, plus self weight generation
Additional force effect, the structure of cable not can guarantee stable homogeneous, this carrys out certain negative shadow to transmission belt of high-frequency signal
It rings, the performance of product is caused to decline, it is unstable.Meanwhile the material of cable itself is also easy fatigue, is accelerated aging, influences the longevity
Life.In addition, the difference of cable length, will lead to its self weight difference, corresponding required flexibility, toughness are also different, however, electricity at present
The apolegamy of cable this respect performance is highly difficult.
Summary of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of elevator vertically accompany digital communication electricity
Cable can be stablized and follow elevator lifting, and flexibility, intensity are more suitable, guarantee that signal is interference-free.
The purpose of the present invention is achieved through the following technical solutions:
A kind of elevator is vertically accompanied cable for digital communication, including from outside to inside successively nested elastic outer sheath, shielded layer,
The conducting wire of elastic inner sheath and strands, the appearance of conducting wire are covered with cellular insulating layer, and elastic outer sheath extends outwardly
It is connected with the attached set of elasticity of even number circular tube shaped, the attached set of elasticity is embedded with the first steel strand rope, and the attached set of elasticity is symmetrically set in outside elasticity
The appearance of sheath；It is equipped with torus shaped cavity in elastic outer sheath, is removably filled with flexible layer in torus shaped cavity.
Further, shielded layer includes plastic-aluminum layers of foil and wire braid, and wire braid is located on the outside of plastic-aluminum layers of foil.
Further, elastic outer sheath is convexly equipped with even number back-off head, is provided on one of back-off head and torus shaped cavity
The through slot of connection, flexible layer are the flexible-belt being wound in torus shaped cavity, and the free end of flexible-belt is stretched out through through slot, and elasticity is attached
It covers side and is equipped with button hole, the free end of flexible-belt is close in button hole back-off in back-off head and shroud；Cracking is provided on remaining back-off head
Slot.
Further, the attached set of elasticity is equipped with the connector for connecting with another attached set of elasticity.
Further, connector includes main body and the hinge hole set on main body two sides, the attached set back-off of elasticity in hinge hole and with
Hinge hole hingedly cooperates, and main body is embedded with the second steel strand rope.
Compared with prior art, the invention has the following beneficial effects:
Conducting wire of the present invention is strands structure, improves the flexibility and bending property of cable, reduces cable and tow
Bending stress in the process；In conjunction with insulating layer using honeycomb (similar foaming) structure, material 40%, medium on the one hand can be saved
It is lost small, further promotes flexibility, not easy to fatigue, aging, meanwhile, the elasticity of elastic inner sheath, elastic outer sheath also improves
The flexibility and bending property of cable, reduces the bending stress during cable tows, wherein stretches on the outside of elastic outer sheath
The symmetrical attached set of elasticity out, forms the booster action of structural strength, can form 360 degree of second protection to cable, guarantee
Cable gravity suffered by the accompanying process of towing and pulling force will not be conducted to the work core of cable, more will not therefore tie
Structure deformation is acted in conjunction with the signal shielding of shielded layer, guarantees that signal transmission of cable during retinue is interference-free；It is more crucial
It is that dismountable flexible layer that the torus shaped cavity in elastic outer sheath is filled can be also arranged according to flex capability demand
The amount of flexible layer is suitable for different length, weight cable and flexibility needed for elevator trailing to reach soft readjustment purpose
Energy.
