Abstract
The utility model discloses a strong interference resistant shielding tensile control cable, which comprises a cable core, a cable forming belting layer, an armoring layer and an outer sheath. The cable core is formed by stranding conductor cores, core insulating layers are arranged on the conductor cores, core shielding layers are further disposed on the outer sides of the core insulating layers of the conductor cores, and a cable core shielding layer is disposed between the cable forming belting layer and an inner protecting layer. The strong interference resistant shielding tensile control cable can restrain strong signal interference existed among cable insulating cores, prevents a connected electronic device from being interfered or out of control, and has the advantages of strong tensile capacity.
Description
Technical field
The utility model relates to a kind of control cable, relates in particular to a kind of control cable with anti-strong jamming and shielding tension function.
Background technology
In the daily life, data communication rates increases rapidly, because communication has not been confined to voice, data, also comprises high-quality picture signal, and with local area network technology, network rate improves rapidly.The external electromagnetic environment is abominable day by day, and new electromagnetic interference source constantly produces.The pulse of various radio broadcastings, forceful electric power switch, fluorescent lamp and mobile communication system all can produce electromagnetic interference, and the electromagnetic interference that mobile communication system especially wherein produces is more and more serious.According to the needs of internet security, the network work frequency is high more, and the radiation of generation is serious more.These radiation might be disturbed other system on the one hand, on the other hand the machine that can hold for the network crime.So require the control cable system to have the ability of opposing strong electromagnetic, promptly can operate as normal under certain electromagnetic interference environment; Require system can not produce excessive electromagnetic radiation on the other hand, promptly can not disturb the operate as normal of other system; And also to have stretching resistance.So require cable that the structure of more perfect anti-interference and stretching resistance can be arranged.
At present the anti-interference structure of the cable of prior art only is that screen such as copper wire braiding is arranged between sheath and insulation, adds shielding armour such as steel band afterwards.It only can suppress the cable external electromagnetic field to the interference of cable with suppress the external interference of cable built-in field, and the strong signal that can not suppress to exist between the cable insulation core disturbs, and is connected that electrical equipment is interfered or out of control thereby make.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that existing cable exists, a kind of anti-strong jamming shielding tensile type control cable is provided, the strong signal that adopts the utility model can suppress to exist between the cable insulation core disturbs, avoid being connected that electrical equipment is interfered or out of control, and also have the strong characteristics of stretching resistance.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of anti-strong jamming shielding tensile type control cable, comprise cable core, stranding belting layer, sheath, armour and oversheath, cable core forms by conductor thread core is stranded, conductor thread core is provided with the core insulating barrier, it is characterized in that: the core insulating barrier of described conductor thread core also is provided with the core screen outward, is provided with the cable core screen between stranding belting layer and the sheath.
Described core screen comprises core lapped shielding layer and the outer core woven shield of core lapped shielding layer that the core insulating barrier is outer.
Described cable core screen comprises cable core lapped shielding layer that the stranding belting layer is outer and the cable core woven shield between cable core lapped shielding layer and the sheath.
Described core lapped shielding layer and cable core lapped shielding layer are that copper is moulded the screen with wrapped structure.
Described core woven shield and cable core woven shield are the screen of copper wire braiding structure.
Described armour is the armour of braided steel wire structure.
Adopt advantage of the present utility model to be:
One, the utility model is outside equipped with the core screen at conductor thread core, has effectively controlled the various interference such as electromagnetic radiation, static coupling and electromagnetic induction that produce between the core.
Two, in the utility model, the core screen adopts the composite shielding structure of core lapped shielding layer and core woven shield, and the various interference effects such as electromagnetic radiation, static coupling and electromagnetic induction that produce between the control core are better.
Three, the utility model is provided with the cable core screen between stranding belting layer and sheath, has effectively controlled extraneous electromagnetic interference, when disturbing appears in circuit, cable itself is not produced any influence.
Four, in the utility model, the cable core screen adopts the composite shielding structure of cable core lapped shielding layer and cable core woven shield, and the electromagnetic interference effect in the control external world is better.
Five, between sheath and oversheath, be provided with armour, not only have shielding action, played good stretching resistance effect, guaranteed cable normally operation under the effect that external force is arranged.
