Abstract

A connector for coupling a coaxial cable to an interface port comprising a capacitor segment configured to interpose a center conductor of a coaxial cable and an RF interface and an outer conductor segment extending over and electrically shielding the capacitor segment. The capacitor segment comprises an inner and outer pin having a dielectric insulator therebetween and is configured to electrically connect an inner conductor of the coaxial cable to the RF interface port. The capacitor segment facilitates the passage of RF energy from the inner conductor of the coaxial cable to the RF interface while inhibiting the passage of electric current through the capacitor segment to the RF interface.

First claim

What is claimed is:

1. A connector for coupling a coaxial cable to a Radio Frequency (RF) interface, comprising:
a capacitor segment including an inner pin, an outer pin coaxially aligned with the inner pin and disposed over at least a portion of the inner pin, and an insulator disposed between at least a portion of the inner pin and the outer pin, the inner and outer pins defining an overlapping region between about 1.5 inches to about 2.3 inches in length and the insulator defining a thickness dimension of between about 0.020 inches to about 0.045 inches and
a conductive outer body segment disposed over and fully enveloping the capacitor segment to electrically shield the capacitor segment;
wherein the capacitor segment is configured to interpose and electrically connect an inner conductor of the coaxial cable and the RF interface thereby facilitating the passage of RF energy from the inner conductor of the coaxial cable to the RF interface while inhibiting the passage of electric current through the capacitor segment to the RF interface.

2. The connector of claim 1 , configured to be coupled to a jumper cable for transmitting the RF energy of a telecommunications device.

3. The connector of claim 1 , wherein the insulator comprises an organic dielectric.

4. The connector of claim 1 , wherein the insulator comprises a polyimide film.

5. The connector of claim 1 , wherein the insulator comprises a ceramic material.

6. The connector of claim 1 , wherein the overlapping region is between about 0.75 inches to about 1.50 inches in length.

7. The connector of claim 1 , further comprising a weatherproofing boot, concentric with a coaxial cable, and configured to slide over the coaxial cable to cover the conductive outer body segment.

8. The connector of claim 1 , wherein the inner pin comprises a socket portion at one end that engages the inner conductor of the coaxial cable.

9. The connector of claim 8 , wherein the socket portion of the inner pin is not disposed within an overlapping region.

10. The connector of claim 1 , further comprising an air gap between the outer pin and an internal surface of the conductive outer body segment.

11. The connector of claim 1 , further comprising an end connector segment configured to electrically and mechanically couple the capacitor segment and the outer body segment to the RF interface.

12. An RF jumper cable comprising:
a coaxial cable segment;
a capacitor segment coupled to the coaxial cable segment, the capacitor segment including an inner pin coupled to an inner conductor of the coaxial cable segment, an outer pin coaxially aligned with the inner pin and disposed over at least a portion of the inner pin, an insulator disposed between at least a portion of the inner pin and the outer pin, and a conductive outer body segment,
the inner and outer pins defining an overlapping region between about 1.5 inches to about 2.3 inches in length and the insulator defining a thickness dimension of between about 0.020 inches to about 0.045 inches,
the conductive outer body segment disposed over and fully enveloping the capacitor segment to electrically shield the capacitor segment; and
a coupling member disposed on an end of the capacitor segment opposite the coaxial cable segment,
wherein the capacitor segment is configured to electrically connect an inner conductor of the coaxial cable segment to an RF interface to facilitate the passage of RF energy through the capacitor segment while inhibiting the passage of electric current through the capacitor segment to the RF interface.

13. The RF jumper cable of claim 12 , wherein the insulator comprises an organic dielectric.

14. The RF jumper cable of claim 12 , wherein the insulator comprises a ceramic material.

15. The RF jumper cable of claim 12 , further comprising a weatherproofing boot, concentric to the coaxial cable and configured to slide over the coaxial RF jumper cable to cover the capacitor segment.

16. The RF jumper cable of claim 12 , wherein the inner pin comprises a socket portion that engages the inner conductor of the coaxial cable.

17. The RF jumper cable of claim 12 , further comprising an air gap between the outer pin and the conductive outer body.

18. The RF jumper cable of claim 12 , wherein the inner and outer pins define an overlapping region, and wherein the overlapping region is between about 0.75 inches to about 1.5 inches in length.
