Problems solved by technology
Threaded connection has the characteristics of high electrical performance and superior electrical performance, but the connection speed is slow, requiring sufficient surrounding space, and it is difficult to achieve fast connection and high-density arrangement
Plug-in type and bayonet type connection are fast, but the electrical performance and anti-vibration performance are poor, so it is difficult to be used in occasions with high requirements
The push-in self-locking connection has the characteristics of fast connection and high reliability, but the ordinary push-in self-locking connector has a complex connection interface structure, and the accumulation of tolerances of multiple dimensions makes the electrical length of the connector interface vary greatly, and the cost is high. It cannot be used in the overall system with higher electrical performance requirements
