Abstract

A connector insert comprising a plurality of layers of conductive elastomer, and a concomitant method of employing a connector insert, the method comprising the steps of fabricating a plurality of layers of conductive elastomer as an insert and placing the insert into a connector.

Claims

1. A flexible unitary connector insert for adding circuitry within a shell and around at least one pin of an existing connector or mating pair of connectors, said connector insert comprising one or more layers of flexible and compressible conductive and non-conductive elastomers that provide all electrical connections and paths throughout said insert and all electrical insulation and isolation throughout said insert, the one or more layers of conductive and non-conductive elastomer comprising an outside perimeter to fit inside an inside perimeter of a cavity of the shell, and at least one opening for fitting around the at least one pin.

2. The connector insert of claim 1 wherein said conductive elastomer creates a ground plane to make an electrical connection between embedded electrical components and/or from one or more of said embedded electrical components to the shell and wherein said ground plane comprises an outside perimeter larger than the inside perimeter of the cavity of the shell when the connector insert is not in contact with the shell, but which compresses to comprise an outside perimeter equal to the inside perimeter of the shell when the connector insert is fit into the shell, wherein the connector insert maintains continuous mechanical and electrical contact around the inside perimeter of the shell.

3. The connector insert of claim 1 wherein the at least one opening of said conductive elastomer comprises a perimeter smaller than the perimeter of the at least one pin when the connector insert is not in contact with the pin, but which expands to comprise a perimeter equal to the perimeter of the pin when the connector insert is fit to the pin, wherein the connector insert maintains mechanical and electrical contact around the perimeter of the pin, said conductive elastomer makes an electrical connection between the pin and at least one other pin and/or embedded electrical components and/or the connector shell, and said conductive elastomer may conduct current between two or more pins.

4. The connector insert of claim 1 wherein the at least one opening of said non-conductive elastomer comprises a perimeter smaller than the perimeter of the at least one pin when the connector insert is not in contact with the pin, but which expands to comprise a perimeter equal to the perimeter of the pin when the connector insert is fit to the pin, wherein the connector insert maintains mechanical contact and electrical insulation around the perimeter of the pin.

5. The connector insert of any one of claims 1, 2, 3 and 4 additionally comprising a capacitor.

6. The connector insert of claim 5 wherein said capacitor comprises a plurality of layers of conductive elastomer with separation provided by at least one layer of non-conductive material.

7. The connector insert of claim 6 wherein said non-conductive material comprises flexible, non-conductive elastomer.

8. The connector insert of claim 7 wherein said non-conductive elastomer of said capacitor has a dielectric constant greater than 1.

9. The connector insert of claim 8 wherein said non-conductive elastomer of said capacitor has a dielectric constant greater than 10.

10. The connector insert of claim 1 placeable at an interface of a mating pair of existing connectors such that an environmental seal is created thereby preventing the passage of dust, fluids, gasses, or other contaminants through the connection.

11. The connector insert of claim 1 placeable internal to an existing connector such that an interface between the existing connector and an existing mating connector is not altered.

12. The connector insert of claim 5 wherein said capacitor comprises a plurality of coplanar segments of conductive elastomer separated by at least one thin strip of non-conductive material.

13. The connector insert of claim 12 wherein said non-conductive material comprises flexible, non-conductive elastomer.

14. The connector insert of claim 13 wherein said non-conductive elastomer of said capacitor has a dielectric constant greater than 1.

15. The connector insert of claim 14 wherein said non-conductive elastomer of said capacitor has a dielectric constant greater than 10.
