Abstract:
A male BNC connector half comprising:a male BNC connector shell having a shouldered bore therethrough and forming at one end a mating cylinder for entering a female BNC connector shell having bayonet pins; a bayonet latch having spiral grooves ending in detents for engaging bayonet pins when the mating cylinder enters the female BNC connector shell, and having a region of external threads; the bayonet latch slidably and non-rotatably affixed to the male BNC connector shell and over the mating cylinder; a center conductor support bead having a central hole therein and that fits snugly in the shouldered bore and rests against an internal shoulder therein when inserted into the shouldered bore from an end opposite the location of the mating cylinder; a threaded retaining member that screws into the shouldered bore at the end opposite the location of the mating cylinder and that contacts the center conductor support bead and holds it against the internal shoulder; a male center conductor pin held coaxially along the axis of the shouldered bore by threaded compression through the central hole in the center conductor support bead and which forms an air dielectric transmission line with the interior of the mating cylinder; a connecting center conductor passing coaxially through a bore in the threaded retaining member, which threadably mates with the male center conductor pin through the central hole in the center conductor support bead to provide the above recited threaded compression, and that is part of a transmission line for carrying signals to and from the male BNC connector half; the male BNC connector shell also having an external shoulder proximate the location where the bayonet latch is affixed thereto; and a draw nut having a bore therethrough with internal threads thereon, having reduced diameter at one end that slides snugly over the outside of the BNC male conductor shell proximate the external shoulder thereon and in a direction that is from the threaded retaining member toward the mating cylinder, in an orientation where the internal threads pass over the external shoulder and rotatably engage the external threads of the bayonet latch.
