[0019] The first embodiment: as figure 1 As shown in the figure, an ultra-high temperature flexible radio frequency coaxial cable for bomb-borne use includes a conductor 1, an insulating layer 2, a shielding layer 3, a barrier layer 4 and a protective sheath arranged on the outside of the conductor 1 in turn. The conductor 1, the insulating layer 2 , the shielding layer 3, the blocking layer 4 and the protective cover 5 are all high temperature resistant materials, the protective cover 5 is a flexible material, and the insulating layer 2 is a low dielectric loss material.

[0020] The insulating layer 2 includes multiple layers of quartz fiber cloth wrapped around the outside of the conductor 1 .

[0021] The winding directions of the quartz fiber cloth between adjacent layers are opposite.

[0022] The blocking layer 4 is a quartz fiber cloth wrapped between the shielding layer 3 and the protective cover 5 .

[0023] A barrier layer 4 composed of quartz fiber cloth is also ...

Abstract

The invention relates to the technical field of radio frequency coaxial cables, in particular to a missile-borne ultrahigh-temperature flexible radio frequency coaxial cable which comprises a conductor, an insulating layer, a shielding layer and a protective sleeve, and the insulating layer, the shielding layer and the protective sleeve are sequentially arranged on the outer side of the conductor and are all made of high-temperature-resistant materials. The high-temperature-resistant flexible cable has the advantages of high temperature resistance, softness and low loss, and compared with the prior art, the high-temperature-resistant flexible cable still has the functions of softness, low loss and the like in high-temperature environments with special requirements of missile-borne, radar and the like.

Description

technical field [0001] The invention relates to the technical field of radio frequency coaxial cables, in particular to an ultra-high temperature flexible radio frequency coaxial cable for missiles. Background technique [0002] Radio frequency coaxial cable is a cable that transmits electromagnetic energy in the radio frequency range. It is also an indispensable component in various radio communication systems and electronic equipment. It is widely used in wireless communication and broadcasting, television, radar, navigation, computers and instruments . RF coaxial cables are usually composed of conductors, insulation layers, shielding layers and protective sheaths. [0003] At present, the commonly used flexible RF coaxial cables are mostly made of polytetrafluoroethylene (PTFE), polyethylene (PE), ethylene tetrafluoroethylene copolymer (ETFE) and other materials. Different materials, the working temperature of polyurethane (TPU) is basically between -55°C and +85°C, and...
