Large power TNC connector for aerospace and assembling method thereof

Abstract

The present invention discloses a large power TNC (Threaded Neill-Concelman) connector for aerospace and an assembling method thereof. The connector comprises a jack, a first pressing sleeve, a second pressing sleeve, an inner insulator, a first outer insulator, a second outer insulator, a casing pipe and a housing which have center lines located at the same axis. The jack comprises a center groove, and a first central hole and a second hole which are arranged at two sides of the center groove. The inner insulator is embedded in the center groove is pressed into the casing pipe through the first pressing sleeve. The first central hole is embedded in the first outer insulator, and the second central hole is embedded in the second outer insulator. The first pressing sleeve is arranged at the outer side of the first outer insulator and between the first outer insulator and the housing. The second pressing sleeve is arranged at the outer side of the second outer insulator and between the second outer insulator and the housing. The large power TNC connector for aerospace and the assembling method thereof realize the high reliability space environment resistance performance of the TNC connector on the basis of ensuring the microwave transmission parameters.

Description

technical field [0001] The invention belongs to the technical field of microwave radio frequency passive devices, and in particular relates to a high-power TNC connector for aerospace and an assembly method thereof. Background technique [0002] The existing TNC (Threaded Neill-Concelman, Neil-Concelman screw port) connector generally adopts the traditional connector structure, and the insulating layer material is generally not used for cost control. The engineering materials used in the field cannot meet the requirements of high-low temperature mutations, high-radiation space environments, and high-power transmission in a vacuum state; moreover, large-area air cavities are often used as microwave transmission carriers, which are prone to generation when transmitting high-power signals exceeding 100W. The phenomenon of micro-discharge causes irreversible damage to the connector, thereby reducing the reliability of the entire product. Therefore, there is an urgent need to de...
