Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] Existing semi-flexible coaxial RF cables have such figure 1 The structure shown includes a coaxial inner conductor 1, an insulator 2, an outer conductor 3 and a sheath 4 sequentially from the inside to the outside, but the copper in the inner conductor 1 is a scarce resource, the cost is high, and the proportion of copper is large, so that Self-weight of semi-flexible coaxial RF cable. The main innovation of the present invention is that silver-plated ...

Abstract

The invention relates to a radio frequency cable internal conductor and a half flexible coaxial radio frequency cable. The inner conductor of the radio frequency cable successively comprises an aluminum conductor core (7), a copper layer (6), and a silver layer (5) from the inside to the outside; the copper layer (6) wraps the outer surface of the aluminum conductor core (7); and the silver layer (5) wraps the outer layer of the copper layer (6). The radio frequency cable internal conductor and half flexible coaxial radio frequency cable adopts the silver-plated alumina as an internal conductor on the premise that the attenuation is low, the standing-wave ratio is small and the bending resistance performance is good. The price is cheap and the aluminum portion which is light replaces the heavy metal copper. As a result, the invention reduces the cost, reduces the self weight and reduces the pollution to the environment.

Description

technical field [0001] The invention relates to the field of radio frequency cables, and more specifically relates to an inner conductor of a radio frequency cable and a semi-flexible coaxial radio frequency cable. Background technique [0002] The semi-flexible coaxial RF cable has excellent properties such as wide operating temperature range, high operating frequency, low attenuation, small standing wave coefficient, and good shielding performance, as well as good bending properties. Therefore, it has been more and more widely used in transmission systems using radio frequency signals such as rockets, satellites, communications, navigation, electronic countermeasures, and measurement and control equipment. [0003] General semi-flexible coaxial RF cables have such figure 1 The structure shown includes coaxial inner conductor 1, insulator 2, outer conductor 3 and sheath 4 from inside to outside. For example, Chinese utility model patent CN2824321Y discloses a semi-flexible...
