Abstract

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

Claims

1. A coaxial connector for passing signals similar to those passed by F-Type connectors, the connector comprising:

a body, an electrical contact, and a metallic waveguide;

the body including a connection that incorporates the electrical contact;

the electrical contact aligned along a body centerline and electrically isolated from the body; and

,

the waveguide fixed within the body and the body centerline passes through a central aperture of the waveguide;

wherein the waveguide faces the electrical contact and is configured to limit entry of stray RF signals into a body region that includes the electrical contact.

2. The connector of claim 1 further comprising:

the waveguide bearing on an internal surface of the body.

3. The connector of claim 1 further comprising:

an electrical insulator;

the insulator and the waveguide in a waveguide assembly; and

,

the insulator insulating a portion of the waveguide.

4. The connector of claim 1 wherein a spring is located between the waveguide and a female port mouth.

5. The connector of claim 4 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.

6. The connector of claim 5 wherein the first bearing surface is an electrical insulator.

20. The connector of claim 16 The connector of claim 1 further comprising:

a second electrical insulator;

the insulator and the waveguide in a waveguide assembly; and

,

the insulator insulating a portion of the waveguide.

7. A coaxial connector for passing signals similar to those passed by F-Type connectors, the connector comprising:

a body and an insulator, the insulator spacing an electrical contact of a female port to a location near a connector central axis;

the electrical contact including a portion wrapped around the connector central axis;

the electrical contact including inwardly directed fingers for contacting a male connector center pin; and

,

a metallic waveguide within the body and a waveguide aperture facing the electrical contact;

wherein the waveguide is configured to limit entry of stray RF signals into a body cavity enclosing the electrical contact when the connector is not in use and the waveguide is configured to receive a center conductor of a male connector when the connector is in use.

8. The connector of claim 7 wherein the waveguide is insulated.

9. The connector of claim 7 wherein the waveguide aperture is insulated.

10. The connector of claim 7 wherein a second insulator supports the electrical contact.

11. A method of electrically shielding a coaxial cable connector for passing signals similar to those passed by F-Type connectors, the method comprising the steps of:

providing a body, an electrical contact, and a metallic waveguide;

supporting the electrical contact along a connector centerline with a first insulator;

fixing the waveguide within the body such that a waveguide aperture is opposite the electrical contact;

when the connector is unmated, the waveguide shielding the electrical contact from stray RF signals that are not able to pass through the waveguide aperture; and

,

when a mating connector conductor is passed through the waveguide aperture and touches the electrical contact, an electrical circuit is established through the connector.

12. The method of claim 11 wherein the waveguide is a part of the body.

13. The method of claim 11 wherein the waveguide is insulated.

14. The method of claim 11 wherein a second insulator is inserted in the waveguide aperture.

15. The method of claim 11 further comprising the step of including the electrical contact in a female port.

16. A coaxial connector for passing signals similar to those passed by F-Type connectors, the connector comprising:

within a body, an electrical contact isolated from the body by a first insulator;

a waveguide with an aperture pointed at the electrical contact; and

,

the waveguide shielding the electrical contact from stray RF signals that are not able to pass through the waveguide aperture.

17. The connector of claim 16 wherein the waveguide aperture is insulated.

18. The connector of claim 17 wherein the waveguide is incorporated in a female port.

19. The connector of claim 17 wherein the waveguide is not incorporated in a female port.
