SMA type radio frequency coaxial connector with novel structure

Abstract

The invention discloses an SMA type radio frequency coaxial connector with a novel structure. The SMA type radio frequency coaxial connector comprises a casing for connecting a cable and a connectingscrew which sleeves an outer side of a front end of the casing. The casing is provided with a threading hole penetrating through the front and the back of the casing, an insulator is engaged at a front end of the threading hole, an inner conductor is engaged in the insulator, a bushing and a screw are orderly set from the inside to the outside at a back end of the threading hole, a front end of the bushing abuts against the insulator, a back end outer side of the bushing is sleeved with a pressing sleeve, and the bushing, the pressing sleeve and the insulator are pressed in the threading holeby screws. The SMA type radio frequency coaxial connector of the invention has the characteristics of compact structure and convenient installation, that an inner conductor does not have relative displacement when the connector is assembled into a cable component to be used and tested can be ensured, and the reliable signal transmission is ensured.

Description

technical field [0001] The invention relates to the technical field of radio frequency coaxial connectors, in particular to an SMA type radio frequency coaxial connector with a new structure. Background technique [0002] The structure of conventional SMA type connectors mated with coaxial cables can be divided into: welding structure, crimping structure, and assembly structure. For cables that are not suitable for outer conductor welding such as SFF type, the assembly structure is mostly used, and the original SMA type connector of the assembly structure, after being assembled into a cable assembly, is repeatedly bent or subjected to high and low temperature tests. , The core wire of the cable will be displaced, causing the inner conductor in the connector to shrink back or push out forward, resulting in poor contact and signal transmission failure. Contents of the invention [0003] The present invention aims at the above-mentioned existing technical defects, and provid...
