First Claim
Patent Images
1. An unswitched F-type connector with ingress reduction shielding and without moving parts, the connector comprising:
- an outer connector body and a coaxially arranged center pin that extends from one end of the body to an opposed end of the body;
a connector female end for engaging a male coaxial cable connector;
a waveguide located in the female connector end, the waveguide in the form of a metallic disc with a central aperture; and
,the waveguide aperture insulated by a first electrical insulator having a through hole for receiving a center conductor of a coaxial cable;
whereinthe waveguide central aperture has a diameter in the range 2.0 mm to 3.0 mm,the insulator has a radial thickness that provides a nominal radial clearance between the center conductor and the insulator of at least 0.19 mm, andthe waveguide is configured to shield connector body internals from ingress of radio frequency signals in the range of 10 to 100 megahertz.

9. A method of shielding a coaxial connector female connection when the connection is not in use and protecting against shorting when the connection is in use, the method comprising the steps of:
-
providing a coaxial cable connector without moving parts; locating an insulated aperture waveguide at a female connection end of the connector; and
,configuring a waveguide web bordering the aperture with a thickness in the range of 0.5 to 1.5 mm; wherein the waveguide has a central aperture with a diameter of 2.0 to 3.0 mm and a radial clearance between a center conductor for insertion in the connector and the insulated aperture is at least 0.18 mm.
