Description

Blind-insertion push-in type connector

Technical Field

The utility model relates to a connector technical field specifically is a blind plug-in push-in connector.

Background

The radio frequency coaxial connector is a bridge for connecting a coaxial transmission line and a microstrip circuit, has the characteristics of wide use frequency band, excellent performance and the like, and is widely applied to various fields of microwave transmission. Due to different application occasions, the radio frequency coaxial connector has connection forms such as threaded connection, bayonet connection, plug-in connection, blind plug and the like. The threaded connection has the characteristics of high reliability, excellent electrical performance and the like, but the threaded connection requires enough installation space and is slow in connection speed, and the quick connection and high-density arrangement and use are difficult to realize. The plug-in type and the bayonet type are connected quickly, but the electrical property and the vibration resistance are poor, so that the plug-in type and the bayonet type are difficult to be used in occasions with higher requirements. The blind-insertion push-type radio frequency coaxial connector has the characteristics of quick connection, high-density arrangement and use and the like, and is applied to a complete machine system with higher electrical performance requirement. However, the conventional blind-insertion push-type radio frequency coaxial connector has smaller sizes of the inner conductor and the outer conductor, high requirements on processing precision, poor stability in high-density arrangement and use, and easy damage and deformation, so the structure requirements on a mounting system are higher.
