This is a 70 GHz blind mate interconnect system utilizing the 1.85 mm interface as an alternative to current SMPM solutions. The push-on interface is created by removing the threads and coupling nut of a 1.85mm interface pair. The outer conductors engage and align before the center conductors engage. There is a cavity in the housing that the male adapter sits in for movement in the X-Y axis. When fully engaged, the housings compress the spring applying the required mating force.    https://signalmicrowave.com/adapters
