Radio frequency coaxial connector with high reliability

Abstract

The invention relates to a radio frequency coaxial connector with high reliability. The radio frequency coaxial connector with high reliability comprises an inner conductor, an insulating support, a first outer conductor, a second outer conductor, a nut and a sleeve, wherein the inner conductor is pressed into the insulating support, the first outer conductor is arranged on the insulating support and is forcedly pressed into the second outer conductor, the nut is arranged on the second outer conductor, the tail portion of the inner conductor is in pressing connection with a central wire, an insulating shielding layer is wrapped on the central wire and is restrained in the sleeve, the nut is directly installed on the second outer conductor, and the second outer conductor prevents the nut from loosening from the butt joint end of the connector. The sleeve is installed on the second outer conductor and prevents the nut from loosening from the tail end of the connector. By means of the multiple-structure design, the connecting reliability of the radio frequency coaxial connector is ensured. By optimizing a designed gap and a protruding structure, the electrical performance index of the connector is ensured, an experiment and actual use prove that the radio frequency coaxial connector meets the using requirements and is remarkable in implementation effect.

Description

technical field [0001] The invention relates to a radio frequency coaxial connector, in particular to a radio frequency coaxial connector with high reliability, belonging to the technical field of electronic components. Background technique [0002] Existing radio frequency coaxial connectors, such as SMA connectors, are widely used standard connectors. Usually, a nut is provided at the butt end of the connector, and a snap ring with a certain elasticity is used to cooperate with the nut to prevent the nut from loosening. However, since the nut often needs to be locked in cooperation with other components, the snap ring connection becomes invalid and the nut is easy to loosen. In addition, the end of the connector is generally crimped with a shielded cable, and the connection between the cable and the connector often falls off or breaks, affecting actual use. Not only that, the cut-off frequency of existing connectors is generally up to 18GHz, and when it is in the range o...

Problems solved by technology

However, since the nut often needs to be locked in cooperation with other parts, the snap ring connection fails and the nut is easy to loosen

In addition, the end of the connector is generally crimped with a shielded cable, and the connection between the cable and the connector often falls off or breaks, which affects the actual use

Not only that, the cut-off frequency of the existing connectors is generally up to 18GHz, and when it is in the range of 10GHz~18GHz, the voltage standing wave ratio is very high, which cannot meet the actual use requirements
