Abstract

A strip line type annular isolator disclosed in the invention comprises a cavity (1), a cover plate (2), a center conductor (3), a left containing cavity (5) and a right containing cavity (6), the left containing cavity (5) and the right containing cavity (6) are arranged in the cavity (1), the left containing cavity (5) is communicated with the right containing cavity (6), two left positioning grooves (7) are formed in the inner wall of the left containing cavity (5) in the axial direction of the left containing cavity (5), and two right positioning grooves (8) are formed in the inner wall of the right containing cavity (6) in the axial direction of the right containing cavity (6). Internal threads are arranged at the upper end of the left containing cavity (5) and the upper end of the right containing cavity (6), external threads (9) are arranged on the outer wall of the cover plate (2), and the cover plate (2) is in threaded connection with the internal threads through the external threads (9). And lower rotating magnetic sheets (10) are supported in the left containing cavity (5) and the right containing cavity (6). The strip line type annular isolator has the beneficial effects of compact structure, improved assembly efficiency, suitability for mass production and good shielding effect.

Description

technical field [0001] The invention relates to the structural field of an annular isolator, in particular to a stripped annular isolator. Background technique [0002] The ring isolator is mainly used in the T / R component of the phased array radar, and plays the role of ring duplexing and isolating the reflected signal in the T / R component. The ring isolator is an integration of a circulator and an isolator. After the integration, the volume of the ring isolator is only 11mm×12mm×4.5mm, and the insertion loss is less than 0.6dB. During the assembly process of the ring isolator, the assembly of the central conductor and the cover plate is particularly important. In the Chinese patent publication number CN210040490U, a ring-shaped isolator is disclosed, wherein the assembly and positioning method of the central conductor is disclosed as follows: the central conductor 3 is provided with a plurality of connecting parts 31; the number of the connecting parts 31 is related to th...
