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 relates to an anti-loosening radio frequency coaxial connector. The anti-loosening radio frequency coaxial connector comprises a casing, wherein the casing is internally provided with a pin and is externally provided with a thread sleeve, the casing comprises a first casing and a second casing, one end of the first casing is provided with a loop of first projections circumferentially, one end of the second casing is provided with a loop of first grooves circumferentially, the first projections and the first grooves are mutually matched, the thread sleeve is sleeved at an outer wall of a connection portion of the first casing and the second casing, a chamber formed by the casing and the pin is provided with an insulator, stop rotation holes are oppositely arranged between contact faces of the insulator and the second casing, the stop rotation holes are internally provided with stop rotation nails, and the stop rotation nails comprise stop rotation nail heads. The anti-loosening radio frequency coaxial connector has a simple structure, can effectively prevent the insulator in the radio frequency coaxial connector from rotating relatively, prevents loosening, excellently guarantees safety and prolongs service life.

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...
