A socket connector and coaxial connector

Abstract

The invention discloses a socket connector and a coaxial connector. The socket connector comprises an outer socket conductor, a socket dielectric and an inner socket conductor. The outer socket conductor is cylindrical and of an inner cylindrical cavity. The inner socket conductor is rod-like and inserted in the inner cylindrical cavity. The socket dielectric is fixed between the outer socket conductor and the inner socket conductor. A circular process groove is formed between the fixed end of the inner socket conductor and the second end of the outer socket conductor, and a floating groove is formed between the connecting end of the inner socket conductor and the first end of the outer socket conductor. Vent holes communicating the floating groove with the process groove are formed in the socket dielectric. As the process groove is formed between the inner socket conductor and the outer socket conductor, the vent holes can guarantee smooth spilling of weld gas during welding, slotting of the outer socket conductor is avoided, the outer socket conductor can fit a PCB to form full shield to avoid radiofrequency leakage of the outer socket conductor after welding, and excellent electromagnetic compatibility is achieved. The coaxial connector comprises the socket connector and an adapter component.

Description

technical field [0001] The invention relates to a signal connector, in particular to a socket connector and a coaxial connector. Background technique [0002] With the development of communication technology, the integration of modules is getting higher and higher, which leads to the EMC (ElectroMagnetic Compatibility, electromagnetic compatibility, generally refers to the coexistence state of electronic and electronic equipment performing their respective functions in a common electromagnetic environment) performance of electronic systems. Increasingly, EMC issues have become critical issues. [0003] Coaxial connectors are widely used in electronic systems to connect two parallel PCBs for signal connection. Coaxial connectors are generally terminated by surface-mount reflow soldering process, so it is necessary to design a welding process groove at the end of the outer conductor, and the welding process groove is directly connected to the outside of the outer conductor, r...

AI Technical Summary

Problems solved by technology

Coaxial connectors are generally terminated by surface-mount reflow soldering process, so it is necessary to design a welding process groove at the end of the outer conductor, and the welding process groove is directly connected to the outside of the outer conductor, resulting in inevitable radio frequency leakage at the welding point, and it is difficult to meet the EMC of the system Require
