Abstract

An interconnection junction for communications cables includes: a first connector; a second connector; and a sealing enclosure having a cavity and formed of a polymeric material, the sealing enclosure comprising an RF-isolating material. The first connector and second connector are joined and reside within the cavity of the sealing enclosure.

First claim

That which is claimed is:

1. An interconnection junction, comprising:
a first connector;
a second connector;
a sealing enclosure having a cavity and formed of a polymeric material, the sealing enclosure comprising an RF-isolating material;
wherein the first connector and second connector are joined and reside within the cavity of the sealing enclosure;
wherein the first connector includes a first central conductor and a first outer conductor, and the second connector includes a second central conductor and a second outer conductor, and wherein when the first and second connectors are engaged, a capacitive element is present between the first outer conductor and the second outer conductor.

2. The interconnection junction defined in claim 1 , wherein the polymeric material of the sealing enclosure comprises a rubber material selected from the group consisting of silicone, fluorosilicone, EPDM, and nitrile.

3. The interconnection junction defined in claim 1 , wherein the RF-isolating material of the sealing enclosure comprises a material selected from the group consisting of silver-plated aluminum, nickel-plated graphite, silver-plated copper, and ferrite- or iron-based alloys.

4. The interconnection junction defined in claim 1 , wherein the RF-isolating material comprises a coating on a surface of the sealing enclosure.

5. The interconnection junction defined in claim 1 , wherein the RF-isolating material comprises a filler in the polymeric material.

6. The interconnection junction defined in claim 1 , wherein the RF-isolating material is impregnated into the polymeric material.

7. The interconnection junction defined in claim 1 , wherein the capacitive element comprises air.

8. The interconnection junction defined in claim 1 , further comprising a first cable attached to the first connector at one end.

9. A sealing enclosure for an interconnection junction of connectors, comprising:
a body portion having a cavity therein, the cavity configured to house an interconnection junction of a first connector and a second connector;
wherein the body portion is formed of a polymeric material that comprises an RF-isolating material; and,
further comprising first and second connectors engaged with each other and residing in the cavity, wherein the first connector includes a first central conductor and a first outer conductor, and the second connector includes a second central conductor and a second outer conductor, and wherein a capacitive element is present between the first outer conductor and the second outer conductor.

10. The sealing enclosure defined in claim 9 , wherein the polymeric material of the sealing enclosure comprises a rubber material selected from the group consisting of silicone, fluorosilicone, EPDM, and nitrile.

11. The sealing enclosure defined in claim 9 , wherein the RF-isolating material of the sealing enclosure comprises a material selected from the group consisting of silver-plated aluminum, nickel-plated graphite, silver-plated copper, and ferrite- or iron-based alloys.

12. The sealing enclosure defined in claim 9 , wherein the RF-isolating material comprises a coating on a surface of the sealing enclosure.

13. The sealing enclosure defined in claim 9 , wherein the RF-isolating material comprises a filler in the polymeric material.

14. The sealing enclosure defined in claim 9 , wherein the RF-isolating material is impregnated into the polymeric material.

15. An interconnection junction, comprising:
a first connector;
a second connector;
a sealing enclosure having a cavity and formed of a polymeric material, the sealing enclosure comprising an RF-isolating material;
wherein the first connector and second connector are joined and reside within the cavity of the sealing enclosure;
wherein the first connector includes a first central conductor and a first outer conductor, and the second connector includes a second central conductor and a second outer conductor, and wherein when the first and second connectors are engaged, a capacitive element is present between the first outer conductor and the second outer conductor; and
wherein the sealing enclosure is configured such that the sealing enclosure contacts at most one of the first and second outer conductors.
