Description
Technical field
The present invention relates to a kind of communication cable, belong to electric wire field.
Background technology
With developing rapidly for various Aero-Space and various basic industries, the application of cable is more and more wider, use condition
It is increasingly harsher, while the requirement to performance indications is more and more, the invention of this kind of cable, primarily directed to using in severe ring
Under border, temperature in use is in -60~260 degrees Celsius of environment, while pursuing lighter weight in terms of cable weight, smaller is outer
Footpath.During electric signal transmission, under the effect of the extraneous factors such as bending, vibration, impact, temperature change, cable is produced in itself
Pulse signal be less than 5mV low noise requirement.
The content of the invention
Patent of the present invention provides a kind of communication cable, is meeting the same of other electrical properties and mechanical performance index requirement
When, moreover it is possible to cable high-low temperature resistant is met, low noise is lightweight, the small requirement of external diameter.
The solution of the present invention is as follows：A kind of communication cable, it is characterized in that conductor uses silver-plated copper conductor, the outer cohering bag of conductor
Tetrafluoroethene insulating barrier, teflon insulation layer is outer to set semiconductive shielding layer to constitute insulated wire cores；A pair of insulated wire cores pair
Filled polytetrafluoroethylene microporous barrier constitutes cable core after strand；Wrapped polytetrafluoroethylene (PTFE) semiconductive band outside cable core, in semiconductive band
The outer silver-plated flat copper band of winding, restrictive coating is set outside silver-plated flat copper band.
The thickness of described silver-plated flat copper band is 0.05mm.
Described restrictive coating is made up of two layers of polyimide composite film and polytetrafluoroethylene floor.
Beneficial effects of the present invention：
1st, high temperature resistant, external diameter are small, lightweight.Cable all uses exotic material, and temperature is used for a long time in -55- in cable
260 DEG C, improve the use environment temperature range of electricity.Cable shield is shielded in the form of wrapped silver-plated flat copper band, this kind
Shielding form benefit is lightweight, and shield effectiveness can reach 100%, external diameter 0.2mm more than smaller than braid shielded, with 2*20AWG
Exemplified by cable model, finished cable external diameter can accomplish below 5.0mm, and this is almost meeting cable electrical performance indexes and machinery
The outside diameter of cable limit minimum value of performance indications.Meanwhile, using the filling of expanded microporous polytetra fluoroethylene-EPTEE film inside cable, reducing electricity
Cable can mitigate cable weight significantly while decay, and by taking 2*20AWG cable models as an example, cable weight can accomplish 47g/m
Below.Above indices, for applying the earning rate on aerospace communications cable very high.
2nd, cable low noise properties are good：Due to, using coating graphite semi-conductive layer, shielding preceding wrapped half in cable insulation
Conductive shield band, cable is being used in frequency range 1KHz to 100KHz frequency ranges by test, under highest temperature in use, cable
The pulse signal peak value of generation is less than 2.7mV, and the noise performance index for fully achieving cable is not more than 5mV requirement.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
