An electrical connector has an outer shroud and a center conductor. The outer shroud has an opening with a first diameter in a center portion of the outer shroud and a second diameter adjacent a second end thereof, the first diameter being smaller than the second diameter. The outer shroud also has a first end providing a physical stop for a female connector that mates with the electrical connector. The female connector has a distal end of an outer conductor that does not engage the outer shroud of the electrical connector.
