Plug and socket for radio frequency connector, and self-locking anti-rotation radio frequency connector

Abstract

The invention relates to a plug and a socket for a radio frequency connector, and a self-locking anti-rotation radio frequency connector. Through the insertion of a first anti-rotation mechanism axially disposed on the end surface of the plug housing and a second anti-rotation mechanism axially disposed on the end surface of the socket housing, the purpose of circumferential rotation of the plug housing and the socket housing is achieved; and by arranging a screw sleeve on the connecting sleeve to lock the internal teeth and arranging a screw sleeve on the screw sleeve to lock the external teeth, the anti-rotation and anti-looseness purpose between the connecting sleeve and the screw sleeve is achieved through the engagements that the screw sleeve locks the internal teeth and the screw sleeve locks the external teeth. The plug and the socket designed by the invention may quickly realize the function of locking and unlocking the screw sleeve in the process of inserting by setting the guide lock groove and the matching locking protrusion, with no need of a safety hole structure, thereby functioning as anti-rotation of the screw sleeve and anti-looseness of the thread, which not onlyimproves the fastening reliability of the product, but also greatly improves installation and disassembly speed of the product, and the work efficiency, and is very convenient to use.

Description

technical field [0001] The invention belongs to the technical field of radio frequency connectors, in particular to a radio frequency connector plug, a socket and a self-locking anti-rotation radio frequency connector. 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] Traditional threaded RF connectors rely on the pre-tightening force of the thread to prevent the thread from loosening, and then add a safety thread hole to prevent the thread from loosening while the thread is tightened. However, with the development of aerospace technology, the threaded connector Fastening requirements are getting higher and higher, and there is a trend of integrated and...

AI Technical Summary

Problems solved by technology

Traditional threaded connectors still have the risk of thread loosening and the defects and insufficiencies of being unable to pack closely and conveniently disassemble in the process of fastening reliability and small space installation and use, as follows:

[0004] (1) After the screw connection and the safety thread hole are fixed, there is still a relative rotation between the two shells of the plug and socket, and then there is a risk of mechanical and electrical performance failure;

[0005] (2) The installation and disassembly process is cumbersome, time-consuming, time-consuming and inefficient;

[0006] (3) Special tools are required for installation and disassembly;

[0007] (4) There are restrictions on the installation space, and it is not suitable for high-density and small-space installation;

[0008] (5) The safety hole positions of plugs and sockets need to match, which requires high installation accuracy;

[0009] (6) The processing technology of the safety hole is difficult and the cycle is long
