Abstract: A retention sleeve (140) placed over the rearward end (116) of the outer (102) of a coaxial plug connector (100) providing a rearward stop for retaining the coupling nut (126) on the housing. The retention sleeve includes an inwardly directed flange (146) along the cable-receiving passageway therethrough for retention of solder preforms (128) within cable-receiving bore (114) of the outer conductive housing (102). The retention sleeve can be of low resistance copper having a thin outer layer (152) of magnetic high resistance metal, defining a self-regulating temperature thermal energy source when subjected to RF current, to reflow solder.

Abstract: A dielectric insert of an electrical connector is retained within a metal shell by a plurality of latching ledges formed integrally with said insert member spaced about the periphery of the outer surface thereof and facing the trailing end during insertion into the shell member, to latchingly engage with corresponding stop surfaces defined along inside surfaces of the metal shell facing the direction opposite from the latching ledges. A lip about the periphery of the trailing end of the insert member engages the leading edge of the shell to define a second stop means, preventing insert movement in both axial directions. The insert is dimensioned for the latching projections defining the latching ledges to be compressed during insertion by bearing against the inside surfaces of the shell member until fully inserted into the shell cavity.
