A connector system comprising: first and second coaxial connectors (12, 14) that each lies on an axis extending in forward and rearward directions, said connectors being moveable together to connect them; said second coaxial connector has a stationary inner contact pad and a stationary outer contact pad that each face primarily rearward; said first coaxial connector has a moveable center contact and a center contact spring that biases said moveable center contact forwardly, and a center stop that limits center contact forward movement; said first coaxial connector has a moveable outer contact that extends around said axis and an outer contact spring that biases said moveable outer contact forwardly, and has an outer stop that limits outer contact forward movement; said moveable center contact (20 has a front end, and said moveable outer contact has a front end with an inward flange that has walls forming an aperture aligned with said moveable center contact to allow said moveable center contact to pass therethrough, wherein said first coaxial connector has a tubular insulator that surrounds said movable center contact, characterized in that said first coaxial connector has a sheet metal shield that surrounds said tubular insulator and that lies within said movable outer contact, wherein said sheet metal shield has an internal flange at its front end that lies against the front end of said tubular insulator and behind the inward flange of said moveable outer contact, and wherein the internal flange of said sheet metal shield forms an aperture through which said moveable center contact can pass without touching the sheet metal shield. first and second coaxial connectors (12, 14) that each lies on an axis extending in forward and rearward directions, said connectors being moveable together to connect them; said second coaxial connector has a stationary inner contact pad and a stationary outer contact pad that each face primarily rearward; said first coaxial connector has a moveable center contact and a center contact spring that biases said moveable center contact forwardly, and a center stop that limits center contact forward movement; said first coaxial connector has a moveable outer contact that extends around said axis and an outer contact spring that biases said moveable outer contact forwardly, and has an outer stop that limits outer contact forward movement; said moveable center contact (20 has a front end, and said moveable outer contact has a front end with an inward flange that has walls forming an aperture aligned with said moveable center contact to allow said moveable center contact to pass therethrough, wherein said first coaxial connector has a tubular insulator that surrounds said movable center contact, characterized in that said first coaxial connector has a sheet metal shield that surrounds said tubular insulator and that lies within said movable outer contact, wherein said sheet metal shield has an internal flange at its front end that lies against the front end of said tubular insulator and behind the inward flange of said moveable outer contact, and wherein the internal flange of said sheet metal shield forms an aperture through which said moveable center contact can pass without touching the sheet metal shield.
