Abstract

The invention relates to an air-tight-seal MMW (millimeter wave) coaxial connector, comprising an inner conductor component, an outer conductor component, an intermediate insulator and two connecting termination points which are respectively arranged at two ends of the outer conductor, wherein the inner conductor component comprises an inner conductor contact pin and two inner conductor jacks; the outer conductor component comprises an outer conductor and an outer conductor pressing sleeve; step surfaces of the outer conductor and one end face of the outer conductor pressing sleeve form an outer conductor groove; the intermediate insulator is arranged in the outer conductor groove; the inner conductor contact pin passes through a though hole in the middle of the intermediate insulator, and two ends of the inner conductor contact pin are respectively inserted into the two inner conductor jacks; and two circular grooves are formed between two end faces of the intermediate insulator and end faces of the two inner conductor jacks respectively. The coaxial connector can realize wide-band microwave transmission, has good radio frequency performance in an MMW band, realizes an air-tight seal function of a wide-band radio frequency connector, meets air-tight application requirements in the environment of high air pressure difference, and greatly improves the vibration resistance performance and the impact resistance performance of a product.

Description

technical field [0001] The invention relates to a millimeter-wave connector, in particular to an air-sealed broadband millimeter-wave coaxial adapter and an assembly method thereof. Background technique [0002] The millimeter wave system has a series of unique advantages such as good directionality, strong penetrating power, and no overlap at the frequency edge. Therefore, millimeter wave communication has more and more applications in the military and civilian fields. Coaxial components have small size, wide frequency band, and are compatible with low frequencies, which is conducive to the miniaturization and light weight of military equipment. Therefore, the application of coaxial components, one of the main carriers of millimeter wave transmission, is gradually increasing. The millimeter-wave coaxial connector, as a basic part of the microwave link connection, is a typical representative. [0003] At present, many units in China are producing millimeter-wave coaxial con...
