Abstract

A shielded coaxial connector including a central conductor and a waveguide to shield the central conductor from RF signals.

First claim

What is claimed is:

1. An F-Type coaxial connector for passing CATV signals, the connector comprising:
a body including a female port coaxially arranged about a centerline;
within the connector body, a moveable contact and a stationary contact, the contacts electrically isolated from the body;
the moveable contact carried by a nose urged by a spring to project from a female port mouth; and,
a gap between opposing ends of the contacts and along the centerline when the female port is not mated with a male coaxial connector;
wherein a projecting portion of the nose is pushed into the body when the female port is mated with a male connector such that the gap is closed and an electrical circuit between the contacts is completed.

2. The connector of claim 1 further comprising:
a waveguide in the form of a disk with a centrally located aperture; and,
the aperture located proximate the gap and providing a passageway for completing the electrical circuit.

3. The connector of claim 2 wherein the aperture is empty when the female port is not mated with a male coaxial connector.

4. The connector of claim 2 wherein the waveguide is configured to limit the passage therethrough of stray RF signals deleterious to CATV operation.

5. The connector of claim 2 wherein the spring is located between the waveguide and the female port mouth.

6. The connector of claim 5 further comprising:
first and second opposing spring end bearing surfaces;
the nose providing the first bearing surface; and,
the waveguide providing the second bearing surface.

7. The connector of claim 6 wherein the first bearing surface is an electrical insulator.

8. An F-Type coaxial connector for passing CATV signals, the connector comprising:
a body, an electrical contact, and a metallic disk shaped waveguide;
the body including a female port coaxially arranged about a centerline;
the electrical contact aligned along the centerline and electrically isolated from the body;
the waveguide in a plane perpendicular to the centerline and bearing on an internal surface of the body; and,
the centerline passing through a central aperture of the waveguide;
wherein the waveguide is configured to limit entry of stray RF signals into a body cavity enclosing the electrical contact.

9. The connector of claim 8 further comprising;
an electrical insulator;
the insulator and the waveguide in a waveguide assembly; and,
the insulator insulating a portion of the waveguide.

10. The connector of claim 8 wherein a spring is located between the waveguide and a female port mouth.

11. The connector of claim 10 further comprising:
a moveable nose for projecting from the port;
first and second opposing spring end bearing surfaces;
the nose providing the first bearing surface; and,
the waveguide providing the second bearing surface.

12. The connector of claim 11 wherein the first bearing surface is an electrical insulator.
