Coaxial connector with plunger

A coaxial cable connector comprising:

• a connector body including a center pin for receiving the center conductor of a male connector;
• a plunger urged by a spring to protrude from a connector body mouth at a connector body first end;
• opposed first and second spring ends, the first spring end resting on a spring base affixed to the body and the second spring end resting on the plunger;
• the spring surrounding an insulated portion of the center conductor wherein the spring is spaced apart from the insulated center conductor;
• a connector body second end opposite the connector body first end and a connector middle therebetween, the spring base being located between the connector first end and the connector middle;
• when the connector is not mated, the center pin is masked from extraneous signals, the spring is extended, and the plunger protrudes from the connector body mouth;
• and,
• when the connector is mated, the center pin receives the center conductor of a male connector, the spring is compressed, and the plunger is moved toward the second end of the connector.
