Abstract

The invention relates to an anti-rotation threaded radio-frequency coaxial connector, which comprises a plug and a socket butted with the plug, wherein the plug comprises a first shell, a threaded sleeve, a connecting sleeve and a spring; the socket comprises a second shell; an annular inner tooth belt is arranged on an inner wall of the connecting sleeve; an annular outer tooth belt is arranged on an outer wall of the second shell; the annular inner tooth belt can be meshed with the annular outer tooth belt; L-shaped guide locking grooves are arranged in the threaded sleeve; locking bumps arearranged on the connecting sleeve; and the connecting sleeve elastically moves in the L-shaped guide locking grooves through the spring, thereby achieving locking and unlocking of the threaded sleeve. The invention further relates to a circumferential anti-rotation mechanism, which comprises the second shell and the connecting sleeve, wherein the annular inner tooth belt is arranged on the connecting sleeve; the annular outer tooth belt is arranged on the second shell; and the annular inner tooth belt can be meshed with the annular outer tooth belt. The anti-rotation threaded radio-frequencycoaxial connector is convenient and fast to disassemble, assemble and use, small in volume, reliable in connection and stable in signal, and the self-locking anti-loose function on the threaded sleeveand the anti-rotation function between the shells when the plug and the socket are in a plug-in deadlocking state can be achieved.

Description

technical field [0001] The invention belongs to the technical field of radio frequency connectors, in particular to an anti-rotation threaded radio frequency coaxial connector and a circumferential anti-rotation mechanism. Background technique [0002] RF coaxial connectors play the role of connecting transmission lines, microstrip circuits and printed circuit boards in microwave transmission. They have the advantages of wide operating frequency and convenient connection. Therefore, they are widely used in aerospace systems, microwave communication engineering and military weapons. . [0003] The traditional threaded RF connector relies on the pre-tightening force of the thread to prevent the thread from loosening, and then adds a safety thread hole to prevent the thread from loosening while the thread is tightened. However, with the development of aerospace technology, the fastening requirements for threaded connectors are getting higher and higher, and there is an integra...
