Abstract

A connector having a conductively coated member is provided, wherein the connector comprises a connector body capable of sealing and securing a coaxial cable, and further wherein the conductively coated member, such as an 0-ring, physically seals the connector, electrically couples the connector and the coaxial cable, facilitates grounding through the connector, and renders an electromagnetic shield preventing ingress of unwanted environmental noise.

Claims

1. A conductive shielding member, for cable connectors, the conductive shielding member comprising:

a conductively coated component, the conductively coated component configured to reside within a cable connector so as to facilitate grounding of the cable connector through the conductively coated component and to help shield against ingress of unwanted electromagnetic interference.

2. The conductive shielding member of claim 1, wherein the conductively coated component is an O-ring that is spraycoated with a conductive coating for conductively sealing and physically sealing the connector.

3. The conductive shielding member of claim 1, wherein the conductive component is formed of an elastomeric material onto which the conductive coating is applied.

4. The conductive shielding member of claim 3, wherein the conductive component includes a highly conductive and highly flexible skin or conductive layer on the outer surface of the conductively coated component.

10. The conductive seal of claim 8, wherein the conductively coated elastomeric member is an O-ring that is spraycoated with a conductive coating so as to facilitate grounding of the cable connector through the conductively coated component and to help shield against ingress of unwanted electromagnetic interference.

11. The conductive seal of claim 8, wherein the conductive elastomeric component includes a highly conductive and highly flexible skin or conductive layer on the outer surface of the conductively coated elastomeric component.

12. The conductive seal of claim 8, wherein the conductive coating is a conductive ink.

13. The conductive seal of claim 12, wherein the conductive ink is silver-based ink.

14. The connector of claim 13, wherein the conductive coating is applied to only a portion of an outer surface of the conductively coated elastomeric component.

15. A method of conductively sealing a coaxial cable connector, the method comprising:

providing a cable connector, having conductive shielding member including a conductively coated component, the conductively coated component configured to reside within the cable connector so as to facilitate grounding of the cable connector through the conductively coated component and to help shield against ingress of unwanted electromagnetic interference;

fixedly attaching a coaxial cable to the coaxial cable connector; and

fastening the connector to an interface port in a manner extending an unbroken electrical circuit from the cable and through the conductively coated component to help effectuate a buffer preventing ingress of electromagnetic noise into the conductively sealed connector.

16. The method of claim 15, further including providing said cable connector, wherein said cable connector further includes a coupling member, and further wherein the conductively coated component electrically seals with the coupling member.
