Problems solved by technology

In the field of aerospace, the harsh environment makes the requirements for the cable components of the whole machine more complicated and diverse. Due to the special conditions such as vacuum, radiation, and large temperature changes in the aerospace environment, the cable components are required to have high reliability, low loss and 700PPM phase Stability requirements, but the current semi-rigid cable assemblies cannot meet the requirements of low loss and 700PPM phase stability at the same time

Embodiment Construction

[0008] Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings:

[0009] Low loss phase stable 700PPM semi-rigid cable assembly, such as figure 1 with figure 2 As shown, it includes a semi-rigid cable 20 and a radio frequency connector 10. The RF connector 10 is composed of an inner conductor 13, an outer conductor 15, a front screw sleeve 11, a shell 14 and a tail sleeve 16. The shell 14 is inserted into the rear end of the front screw sleeve 11 and fixed with a snap ring 12. The first insulator 18 is inserted into the Installed in the shell 14, the front side of the shell 14 is closed to prevent the first insulator 18 from falling out; the inner conductor 13 is supported in the shell 14 through the first insulator 18, and the head end of the inner conductor 13 extends into the central thread of the front screw sleeve 11 In the hole, the inner conductor 13 is used for welding with the core wire of the semi-rigid cabl...

Abstract

The invention discloses a low-loss stationary-phase 700PPM semi-rigid cable assembly which comprises a semi-rigid cable and RF connectors connected to the two ends of the semi-rigid cable respectively. Each RF connector is composed of an internal conductor, an external conductor, a front threaded sleeve, a casing and a tail sleeve, the casing is inserted into the rear end of the front threaded sleeve and fixed by a clasp, a first insulator is inserted into the head portion of the casing, the internal conductor is supported in the casing by the first insulator, and the head end of the internal conductor extends into a central threaded hole of the front threaded sleeve; the external conductor is inserted into the casing, and the rear end surface of the external conductor is isolated from the rear end surface of the internal conductor via a second insulator; and the rear end of the casing is connected with the tail sleeve via threads. The semi-rigid cable assembly is characterized by low voltage standing-wave ratio, low loss, stationary stability of 700PPM and the like, and can meet requirements for the aerospace environment.

Description

technical field [0001] The invention relates to a radio frequency coaxial cable assembly, in particular to a low-loss phase-stable 700PPM semi-rigid cable assembly. Background technique [0002] In the microwave system, the radio frequency coaxial cable assembly is an indispensable component, with many varieties and wide applications, and is widely used in many fields including airborne, aviation, and aerospace. In the field of aerospace, the harsh environment makes the requirements for the cable components of the whole machine more complicated and diverse. Due to the special conditions such as vacuum, radiation, and large temperature changes in the aerospace environment, the cable components are required to have high reliability, low loss and 700PPM phase Stability requirements, but the current semi-rigid cable assemblies cannot meet the requirements of low loss and 700PPM phase stability at the same time. Contents of the invention [0003] Aiming at the defects existing...
