Background technology
In the very strong operational environment in magnetic field, the structure of often selecting for use is multi-layer braided shielding, every layer density reaches more than 95%, though this structure interference in magnetic field has to external world played certain effect, but problems have also been brought, (1) bending radius strengthens, strengthened that to lay space (2) integral product not soft, bending (3) weight not freely increases the weight of the cable of above structure, all can not satisfy the user in the frequent mobile instructions for use of the environment of high-intensity magnetic field, at the instructions for use of user's particular surroundings, this kind cable has been carried out brand-new structural design and this cable has been developed.
By searching relevant technical data, sought several in the environment of high-intensity magnetic field the structure of cable, relatively divide shielding wrapped plastic-aluminum combined film behind the pair twist by analysis, the rate of putting up is more than 50%, coverage rate 100%.The zinc-plated shielding braid density of braiding reaches more than 93% behind total stranding, the semi-directional polytetrafluoroethylene film of wrapped softness before and after the shielding, then sheath braiding alkali-free glass wool and apply ptfe emulsion and become super gentle, anti-strong electromagnetic wave interference, double shield, the light-duty control cable of two sheath special type.
Summary of the invention
In order to remedy present technical problem, the purpose of this utility model is to provide a kind of novel super gentle, anti-strong electromagnetic wave to disturb extraordinary light-duty control cable for satellite mobile communication equipment and crucial matching component, this cable by preferred material with optimize structure, satisfy frequent mobile and bending, transmission quality is stable in the environment of strong-electromagnetic field.
The specific design scheme that the utility model adopts is as follows:
To achieve the above object, the utility model adopts following design:
