Problems solved by technology

At present, many RF coaxial connectors have no anti-rotation design, or only add knurling to stop the rotation in the shell hole, but after the harsh environment, after the insulator is deformed, the knurling may have little effect or fail, and it is difficult to meet the torque requirements. The performance is not well guaranteed, reducing the service life

Abstract

The invention discloses a novel radio frequency coaxial connector. The novel radio frequency coaxial connector comprises a housing; an inserting pin is arranged in the housing, and while a screw sleeve is arranged at the outside of the housing; the housing comprises a first housing body and a second housing body; an insulator is arranged in a cavity formed by the housing and the inserting pin; a plurality of rotating stopping parts which are symmetrically arranged along a center line of the housing are arranged between the insulator and the contact surface of the second housing body; one end of each rotating stopping part is inserted into the insulator, and while the other end of each rotating stopping part is fixedly arranged in the second housing body. The novel radio frequency coaxial connector is simple in structure; the rotating stopping parts are arranged between the insulator and the contact surface of the second housing, thus the insulator in the radio frequency coaxial connector can be effectively prevented from relative rotating as well as loosening, and as a result, the safety is ensured well, and the service life is prolonged.

Description

technical field [0001] The invention relates to coaxial connection technology, in particular to a loose-proof radio frequency coaxial connector. Background technique [0002] There are many varieties of RF coaxial connectors, a wide range of uses, and a very large amount of use. At present, they have been widely used in many fields including aviation and aerospace. Due to the development of communications, aviation, aerospace and other industries, the frequency of use of radio frequency coaxial connectors has increased. Through harsh environments such as soldering furnaces, due to the large thermal shrinkage and expansion of insulating materials, which cannot be fully restored, the insulators are deformed. Loosening and rotating with the shell will cause the connector's connection performance and electrical performance to be abnormal. Therefore, it is particularly urgent to design an anti-rotation RF coaxial connector. According to the connection torque specified by the nat...
