High-performance coaxial connector in flexible contact with PCB

Abstract

The invention relates to the technical field of a connector and particularly relates to a high-performance coaxial connector in flexible contact with a PCB. A spring and a needle head are sequentiallyconnected with one end of an inner conductor assembly, the inner conductor assembly extends out of a first shell through the needle head to make contact with an external PCB so that the inner conductor assembly can be electrically connected with the PCB, welding or crimping can be avoided, repeated use can be achieved, and follow-up maintenance and replacement are facilitated; when loosening occurs between a coaxial connector and the PCB, the spring enables the needle head to continuously extend out of the first shell through the restoring force of the spring, so the coaxial connector is madeto be always electrically connected with the PCB, a problem of poor matching of the connector caused by poor contact or improper installation is effectively reduced, matching reliability is improved,and matching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a high-performance coaxial connector with flexible contact with a PCB board. Background technique [0002] RF coaxial connectors are widely used in the interconnection between circuit boards, circuit boards and RF modules. In the electronic communication industry, due to market considerations, miniaturization and low cost are particularly important, which prompts the modularization of electronic communication products to become higher and higher. At present, most of the mainstream products of this type of connectors in the market adopt surface mount or perforated welding, and all of them need to use welding process, which is more troublesome. First, the inner conductor of the RF coaxial connector is welded to the inner conductor of the PCB board under test by soldering, etc., and then the connector and the outer conductor of the PCB board are connected together by means of sc...

AI Technical Summary

Problems solved by technology

First, the inner conductor of the RF coaxial connector is welded to the inner conductor of the PCB board under test by soldering, etc., and then the connector and the outer conductor of the PCB board are connected together by means of screws. The test results are affected by the welding quality, such as the size of the solder joints, the product grounding and other factors. The requirements for the welding process level are relatively high. Improper fabrication will cause damage to the PCB board and affect the performance of the whole machine.
