Abstract

A connector and shielding ring for use with the connector includes a male portion with a shroud and a center conductor and a female portion with a jack and a socket positioned to receive the center conductor. A conductive shielding ring is positioned between the mated connector portions. The shielding ring has a body configured for surrounding flexible tines of the female portion jack and is configured to be captured between the tines and the shroud for providing a grounding path between the male and female portions of the connector. The shielding ring body has an inner surface with a diameter and an outer surface with a diameter and has a taper portion formed on a distal end of the shielding ring body for engaging a surface of the shroud. The shielding ring body has a lip extending radially inwardly at the proximal end for engaging the tines of the female portion when the male and female portions of the connector are mated.

First claim

What is claimed is:

1. A connector comprising:
a male portion and a female portion configured for mating with the male portion;
the female portion including at least one flexible element;
a conductive shielding ring having a cylindrical body configured for surrounding the at least one flexible element of the female portion for providing a grounding path between the male and female portions of the connector when they are mated;
the shielding ring body having an inner surface and an outer surface and having a taper portion extending radially inwardly on a distal end of the shielding ring body for engaging a surface of the male portion;
the shielding ring body having a lip extending radially inwardly at the proximal end of the shielding ring for engaging the at least one flexible element of the female portion when the male and female portions of the connector are mated.

2. The connector of claim 1 further comprising a chamfered surface in the male portion, the taper portion of the shield ring configured for abutting the chamfered surface when the male portion and female portion are mated.

3. The connector of claim 1 wherein the lip is configured for engaging a base of the at least one flexible element for securing the female portion with the male portion when they are mated.

4. The connector of claim 1 wherein the lip extends radially inwardly on the shielding ring body and terminates in a radiused end, the radiused end of the lip configured for rotating on the at least one flexible element of the female portion for rotating the shielding ring.

5. The connector of claim 1 wherein the thickness between the inner surface and outer surface of the shielding ring body is in the range of 0.004 to 0.008 inches.

6. The connector of claim 1 , wherein the body of the shield ring includes a slot formed therein for allowing compression of the body when the male and female portions of the connector are mated.

7. The connector of claim 1 wherein the shielding ring body has a length in the range of 0.07 to 0.08 inches.

8. The connector of claim 1 wherein the taper portion angles radially inwardly from at an angle from a longitudinal axis of the shielding ring body in the range of 27 to 35 degrees.

9. The connector of claim 1 wherein the taper portion includes a taper section on the outer surface of the shielding ring body and at least one radiused section proximate the taper section.

10. The connector of claim 9 wherein the at least one radiused section includes at least one of a tip radiused section at the distal end of the shielding ring body or an outer diameter radiused section proximate the distal end of the shielding ring body.

11. A shielding ring for providing a grounding path between opposing portions of a connector when the connector portions are mated, the shielding ring comprising:
a conductive body having an inner surface and an outer surface, the body inner surface configured for surrounding an outer surface of a flexible element of a first connector portion;
a taper portion extending radially inwardly on a distal end of the conductive body, the taper portion configured for engaging an inner surface of a second connector portion that surrounds the conductive body and the first connector portion when the connector portions are mated;
a lip extending radially inwardly at the proximal end of the of the conductive body for engaging the flexible element of the first connector portion of the connector when the connector portions are mated.

12. The shielding ring of claim 11 wherein the lip extends radially inwardly and terminates in a radiused end, the radiused end of the lip configured for rotating on a first connector portion for rotating the shield ring.

13. The shielding ring of claim 11 wherein the taper portion includes a taper section on the outer surface of the conductive body and at least one radiused section proximate the taper section.

14. The shielding ring of claim 11 wherein the at least one radiused section includes at least one of a tip radiused section at the distal end of the conductive body or an outer diameter radiused section proximate the distal end of the conductive body.

15. The shielding ring of claim 11 wherein the conductive body has a thickness between the inner surface and outer surface of the conductive body in the range of 0.004 to 0.008 inches.

16. The shielding ring of claim 11 , wherein the conductive body includes a slot formed therein for allowing compression of the conductive body when the first and second connector portions are mated.

17. The shielding ring of claim 11 wherein the conductive body has a length in the range of 0.07 to 0.08 inches.

18. The shielding ring of claim 11 wherein the taper portion angles radially inwardly at an angle from a longitudinal axis of the body in the range of 27 to 35 degrees.

19. The shielding ring of claim 11 wherein the first connector portion is a female portion having flexible tines and the second connector portion is a male portion having a shroud to surround the flexible tines when the connector portions are mated, the taper portion configured for engaging an inner surface of the shroud and the lip configured for engaging the flexible tines.

20. The shielding ring of claim 19 wherein the taper portion is configured for abutting a chamfered surface in the shroud of the male portion.
