Shielded and multishielded coaxial connectors
A shielded coaxial connector with a moveable center conductor and a stationary center conductor, the center conductors forming a disconnect switch that interoperates with a waveguide to shield one of the center conductors from radio frequency signals such as radio frequency signals carried by the other center conductor.
1. A shielded male F type coaxial connector for terminating a coaxial cable, the connector comprising:
a fastener coupled to a grip, the fastener for engaging a mating connector and the grip for engaging a coaxial cable;
the grip including a post inserted in a body;
a ram inserted in the fastener and a spring that urges a ram free end to protrude from a fastener mouth;
a ram free end aperture for receiving a center conductor;
the ram, ram free end aperture, center conductor, spring, body, post, and fastener in coaxial arrangement; and,
the ram free end moved toward the post when the fastener is advanced onto the mating connector.
2. The connector of claim 1 wherein the spring does not encircle the body or the post.
3. The connector of claim 1 wherein the spring encircles the post but does not encircle the body.
4. The connector of claim 1 wherein the spring encircles the body and the post.
5. The connector of claim 1 wherein the center conductor moves with the ram.
6. The connector of claim 1 wherein the center conductor is a coaxial cable center conductor.
7. The connector of claim 6 wherein the ram provides an electromagnetic shield about the center conductor when the ram free end protrudes from the fastener mouth.
8. The connector of claim 7 wherein the aperture has a maximum dimension of 3.0 mm.
9. The connector of claim 8 wherein the aperture passes through a free end wall having a thickness normal to the aperture centerline in the range of 0.5 to 1.5 mm.
10. The connector of claim 9 wherein the ram is made from a metal.
