Abstract
The invention discloses a high-frequency stationary-phase semisteel radio frequency cable. The cable comprises: an inner conductor (1) and a dielectric layer (2) which is arranged out of the inner conductor (1). The cable is characterized in that: a material of the inner conductor (1) is copper plated with silver; the material of the dielectric layer (2) is foaming PTFE; the dielectric layer (2) winds on the inner conductor (1) through a wrapping mode; a tubular shielding layer (3) is sleeved out of the dielectric layer (2). By using the high-frequency stationary-phase semisteel radio frequency cable of the invention, usage frequency is high; a propagation rate is fast; temperature phase is lower than 500 PPM. Electrical performance and mechanical property are excellent. The invention can be widely applied in various high-end occasions and the invention has many other advantages.
Description
Technical field
The present invention relates to a kind of cable, relate in particular to the steady phase half steel of a kind of high frequency radio frequency cable.
Background technology
In the radio-frequency communication field, the abominable occasion of environment such as national defence and precision measurement all needs various high-end radio frequency semi-rigid cable assemblies., it is solid in dielectric layer that half steel cable in the market mostly is polytetrafluoroethylene (PTFE), and only a few adopts wrapped low density PTFE as dielectric layer.Use frequency of utilization that these two kinds of materials can cause product as dielectric layer extremely majority be no more than 6Ghz, transmission rate has only 70% and 76%.And the temperature phase place is very high, crosses 1000PPM at normal 40 ℃～80 ℃ wide-ultras of serviceability temperature, even reaches thousands of PPM.Extensive development along with domestic all kinds of high-end equipment, all kinds of radio-frequency devices are widely used in the wireless communication system, the research and development of radio-frequency devices, design and production are flourish at home, requirement to semi-rigid cable is increased thereupon, and present product can not satisfy the demand of various high-end occasions.
Summary of the invention
The objective of the invention is to overcome defective of the prior art, a kind of speed is provided, temperature phase stability and the good steady half steel mutually of the high frequency radio frequency cables of performance index such as decay.
Technical scheme of the present invention provides the steady phase half steel of high frequency radio frequency cable, comprise inner wire and outside dielectric layer thereof, it is characterized in that: described internal conductor material is that copper is silver-plated, described dielectric layer material is expanded polytetrafluoroethyl(ne (LD-PTFE), described dielectric layer is wrapped in described inner conductor by wrapped mode, and described dielectric layer is with tubular screen outward.
Preferably, described screen is a seamless copper tube.
Preferably, described screen is coated with ternary alloy three-partalloy outward, is used to avoid screen oxidized.
Preferably, described screen inwall is close to described dielectric layer.
Preferably, described screen is that processes by drawing forms.
The steady phase half steel of high frequency of the present invention radio frequency cable has the frequency of utilization height, and propagation rate is fast, and the temperature phase place is lower than advantages such as 500PPM.Its electric property and mechanical performance excellence can be widely used in various high-end occasions.
Description of drawings
Fig. 1 is the structural representation of the steady phase half steel of high frequency of the present invention radio frequency cable.
Among the figure: inner wire 1, dielectric layer 2, screen 3.
Embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, the steady phase half steel of high frequency of the present invention radio frequency cable comprises inner wire 1, dielectric layer 2, screen 3.Wherein, the material of inner wire 1 is that copper is silver-plated, and dielectric layer 2 is expanded polytetrafluoroethyl(ne (LD-PTFE), and dielectric layer 2 is wrapped in above the inner wire 1 by wrapped mode.Screen 3 is a seamless copper tube, and seamless copper tube is enclosed within outside the dielectric layer 2 by the technology of drawing, and its inwall is close to dielectric layer 2, and its surface is coated with ternary alloy three-partalloy, and is not oxidized in order to protection copper tube itself.
By the development and testing of actual product, its electric property and mechanical performance can reach customer requirement fully, surpass existing product in the market.Its frequency reaches as high as 40Ghz, and propagation rate reaches 81%.The temperature phase place is no more than 500PPM in normal 40 ℃ of-80 ℃ of scopes of serviceability temperature, be far superior to like product.
Above embodiment only is the present invention's a kind of execution mode wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
