Abstract

A coaxial connector with an F female end shield is configured to restrict RF ingress.

Claims

1. A coaxial connector without moving parts provides ingress reduction shielding, the connector comprising:

an outer connector body and a coaxially arranged center pin;

a connector female end for receiving a mating connector center conductor;

a metallic waveguide located in the female connector end, the waveguide having a central aperture;

a first electrical insulator inserted in the waveguide aperture, the insulator having a through hole for receiving the mating connector center conductor;

the waveguide aperture having a diameter greater than an outer diameter of the mating connector center conductor and less than or equal to 3.0 mm; and

,

the waveguide configured to shield connector body internals from the ingress of radio frequency signals.

2. The connector of claim 1 wherein a waveguide web in which the waveguide aperture is formed is interposed between the first insulator and a second insulator.

3. The connector of claim 1 wherein the first insulator has first and second opposed ends, the first end for receiving the mating connector center conductor and the second end for being received by the waveguide aperture.

4. The connector of claim 1 wherein the connector is an “

F”

type connector and the mating connector center conductor is a coaxial cable center conductor.

5. The connector of claim 1 wherein the first insulator has a radial thickness that provides a nominal radial clearance between the mating connector center conductor and the insulator of at least 0.19 mm.

6. A coaxial connector with ingress reduction shielding, the connector comprising:

an outer connector body and a coaxially arranged center pin;

a connector female end for receiving a mating connector center conductor;

a metallic waveguide located in the female connector end;

the waveguide having a central aperture, a surface facing the center pin, and a surface facing away from the center pin;

a first electrical insulator inserted in the waveguide aperture and covering a portion of the surface facing away from the center pin;

the center pin between the first electrical insulator and an end opposite the connector female end;

the insulator having a through hole for receiving the mating connector center conductor;

the waveguide aperture having a diameter greater than an outer diameter of the mating connector center conductor and less than or equal to 3.0 mm; and

,

the waveguide configured to shield connector body internals from the ingress of radio frequency signals.

7. The connector of claim 6 wherein a waveguide web in which the waveguide aperture is formed is interposed between the first insulator and a second insulator.

8. The connector of claim 6 wherein the first insulator receives the mating connector center conductor and wherein the waveguide aperture receives the first insulator.

9. The connector of claim 6 wherein the connector is an “

F”

type connector and the mating connector center conductor is a coaxial cable center conductor.

10. The connector of claim 6 wherein the first insulator has a radial thickness that provides a nominal radial clearance between the mating connector center conductor and the insulator of at least 0.19 mm.

11. An F-Type coaxial connector without moving parts provides ingress reduction shielding, the connector comprising:

an outer connector body and a coaxially arranged center pin;

a connector female end for receiving a mating connector center conductor;

the female end including an a first insulator followed by a metallic waveguide, the metallic waveguide followed by a second insulator supporting the center pin, and the second insulator abutting the waveguide; and

,

a waveguide aperture having a diameter greater than an outer diameter of the mating connector center conductor and less than or equal to 3.0 mm;

wherein the first insulator has a radial thickness that provides a nominal radial clearance between the mating connector center conductor and the insulator of at least 0.19 mm.

12. The connector of claim 11 wherein a waveguide web in which the waveguide aperture is formed is interposed between the first insulator and a second insulator.

13. The connector of claim 11 wherein the waveguide includes a cylinder and a cylinder partition that defines an aperture within the cylinder, the cylinder partition being removed from the ends of the cylinder.

14. The connector of claim 11 wherein a waveguide cross-section presents both an “

S”

shaped section and a “

Z”

shaped section.
