Abstract
Abstract An electrical connector assembly including a male plug having a male inner conductor and a cylindrical male outer conductor surrounding the inner conductor and having an annular outer surface portion; a female plug having a female inner conductor and a cylindrical female outer conductor surrounding the female inner conductor and having an annular inner surface portion surrounding the outer surface portion, and an annular electrically conductive coil spring extending around the outer surface portion and engaged between the inner and outer surface portions and wherein the spring is adapted to exert therebetween forces that cause axial loading between the male and female outer conductors. In addition to locking the male plug to the female plug, the electrically conductive coil spring enhances the electrical connection between the outer conductors and improves radio frequency interference suppression.
