Abstract
The utility model discloses a low noise high temperature coaxial radio frequency cable, including inner conductor layer, insulating layer, external coating and restrictive coating, be equipped with the insulating layer outside the inner conductor layer, the insulating layer is equipped with the external coating outward, the external coating is equipped with the restrictive coating outward. Silver -coated copper wire is adopted on its inner conductor layer, and the insulating layer adopts polytetrafluoroethylene, external coating adoption graphite, the cladding has polytetrafluoroethylene composite films on the graphite, and the restrictive coating adopts and gathers second propylene of perfluor. The utility model discloses an adopt graphite and polytetrafluoroethylene composite films to combine together the external coating to the homogeneity of product apparent mass and graphite external coating has been improved.
Description
Technical field
The utility model relates to a kind of low noise high-temperature coaxial radio-frequency cable, and it is many that this product is mainly used in industry, medical science, national defence etc.
The measurement of individual field tiny signal.
Background technology
At present, after the like product of domestic production mainly has polyethylene insulation extrusion depanning, owing to sterilization layer is in molten condition,
Directly crossing graphite powder box, graphite powder is coated on insulating barrier, but the temperature resistant grade up to 120 DEG C of this kind of insulation；As poly-four
PVF insulate, and heatproof is up to more than 250 DEG C, but pushes owing to its machine-shaping belongs to normal temperature, and insulation is not easy to adhere to stone
Ink, needs surface specially treated or uses binding agent, and so processing is more complicated, and uniformity is bad.
Utility model content
Utility model purpose: the purpose of this utility model is to solve deficiency of the prior art, it is provided that a kind of low noise high temperature
Coaxial radio frequency cable.
Technical scheme: a kind of low noise high-temperature coaxial radio-frequency cable described in the utility model, including inner conductor layer, insulating barrier,
External coating and restrictive coating, described inner conductor layer is externally provided with insulating barrier, is surrounded with external coating, described external coating outside described insulating barrier
It is externally provided with restrictive coating.
Further, described inner conductor layer uses silver-coated copper wire, a diameter of 0.20-0.40mm.
Further, described insulating barrier uses polytetrafluoroethylene (PTFE) to make, and outer insulation diameter is 0.8-0.9mm, and thickness is 0.2-0.3mm.
Further, described external coating uses graphite and polytetrafluoroethylene (PTFE) laminated film, and the integral thickness of film is 0.25mm, wrapped
Time the rate of putting up reach more than 40%.
Further, described restrictive coating uses perfluoroethylene-propylene to make.
Beneficial effect: the utility model by using graphite to combine with polytetrafluoroethylene (PTFE) laminated film by external coating, thus improves
Product apparent mass and the uniformity of graphite external coating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of low noise high-temperature coaxial radio-frequency cable as shown in Figure 1, including inner conductor layer 1, insulating barrier 2, external coating 3 and
Restrictive coating 4, described inner conductor layer 1 is externally provided with insulating barrier 2, is surrounded with external coating 3, described external coating 3 outside described insulating barrier 2
It is externally provided with restrictive coating 4.
Further, described inner conductor layer 1 uses silver-coated copper wire, a diameter of 0.20-0.40mm.
Further, described insulating barrier 2 uses polytetrafluoroethylene (PTFE) to make, and outer insulation diameter is 0.8-0.9mm, and thickness is 0.2-0.3mm.
Further, described external coating 3 uses graphite and polytetrafluoroethylene (PTFE) laminated film, and the integral thickness of film is 0.25mm, around
During bag, the rate of putting up reaches more than 40%.
Further, described restrictive coating 4 uses perfluoroethylene-propylene to make.
For improving product apparent mass and the uniformity of graphite external coating, we use graphite to tie mutually with polytetrafluoroethylene (PTFE) laminated film
Close, by this film by winding machine, uniformly around wrapping in outside insulation, as graphite external coating.This form processing, outside graphite
Coating is more uniform.
The above, be only preferred embodiment of the present utility model, and the utility model is not made any pro forma restriction,
Although the utility model is disclosed above with preferred embodiment, but it is not limited to the utility model, any is familiar with this specialty
Technical staff, in the range of without departing from technical solutions of the utility model, when the technology contents of available the disclosure above is made a little
Change or be modified to the Equivalent embodiments of equivalent variations, as long as being the content without departing from technical solutions of the utility model, according to this reality
Any simple modification, equivalent variations and the modification made above example by novel technical spirit, all still falls within this practicality new
In the range of type technical scheme.
