High-temperature-resistant floating welding type radio-frequency coaxial cable connector

Abstract

The invention provides a high-temperature-resistant floating welding type radio-frequency coaxial cable connector. The high-temperature-resistant floating welding type radio-frequency coaxial cable connector comprises a shell, a ceramic insulator, an outer contact element, two inner contact elements, two springs, an inner conductor, a ceramic supporting piece and a welded tube, wherein the inner conductor, the ceramic insulator and the shell are sequentially nested in a close fit mode from inside to outside, the ceramic insulator is axially fixed by the outer contact element, the front end and the rear end of the inner conductor are respectively provided with one inward-concave insertion hole, and the two springs are arranged in the two inward-concave insertion holes respectively. The high-temperature-resistant floating welding type radio-frequency coaxial cable connector is simple in structure and ingenious in design, will not soften or deform at a high temperature due to the adoption of a high-temperature-resistant ceramic insulation material, and prevents the situations that a connection mechanism between a cable and a female connector becomes poorer in retentivity at a high temperature and normal signal transmission is affected.
