Abstract

A grounding connector includes a shell having a mating end and a mounting end. The shell defines a cavity open at the mating end configured to receive a mating component. The shell has a base at the mounting end having a plurality of contact channels open to the cavity. Grounding contacts are received in corresponding contact channels. The grounding contacts have mating ends and compliant portions opposite the mating ends. The mating ends are positioned in the cavity for mating with the mating component. The compliant portions are received in the contact channels to mechanically and electrically connect each of the grounding contacts to the shell and to each other through the shell.

First claim

What is claimed is:

1. A grounding connector comprising:
a shell having a mating end at a front of the shell and a mounting end at a rear of the shell, the shell defining a cavity open at the mating end configured to receive a mating component, the shell having a base at the mounting end having a plurality of contact channels open to the cavity, the base having a mounting surface; and
grounding contacts received in corresponding contact channels and entirely contained forward of the mounting surface, the grounding contacts having mating ends and compliant portions opposite the mating ends, the mating ends and the compliant portions forward of the mounting surface, the mating ends being positioned in the cavity for mating with the mating component, the compliant portions being received in the contact channels to mechanically and electrically connect each of the grounding contacts to the shell and to each other through the shell.

2. The grounding connector of claim 1 , wherein the compliant portions are directly supported by the shell and physically engage the shell to electrically connect to the shell.

3. The grounding connector of claim 1 , wherein the compliant portions are press-fit into the shell.

4. The grounding connector of claim 1 , wherein the compliant portions are eye-of-the-needle pins.

5. The grounding connector of claim 1 , wherein each compliant portion includes an enlarged area defined by bulged beams on opposite sides of an opening, the enlarged area initially being wider than the contact channel such that the bulged beams interfere with the base when loaded into the contact channel, the bulged beams being deflected inward into the opening such that the bulged beams are spring biased outward against the base to mechanically and electrically connect to the base.

6. The grounding connector of claim 1 , wherein the grounding contacts are rear loaded through the base, the grounding contacts having flanges at rear ends of the grounding contacts engaging the base to locate the grounding contacts within the shell.

7. The grounding connector of claim 1 , wherein the grounding contacts are front loaded into the base from the cavity, the grounding contacts having flanges forward of the compliant portions engaging the base to locate the grounding contacts within the shell.

8. The grounding connector of claim 1 , wherein the contact channels are wider at a rear of the base and narrower at a front of the base.

9. The grounding connector of claim 1 , wherein the base includes a pocket at a rear of the base, the grounding contacts being loaded into the contact channels through the pocket, the pocket being filled with a rear pocket seal after the grounding contacts are loaded into the shell.

10. The grounding connector of claim 1 , wherein the shell holds an interfacial seal in the cavity at the base, the interfacial seal having contact openings aligned with corresponding contact channels, the mating ends of the grounding contacts passing through the contact openings in the interfacial seal such that the interfacial seal seals to each of the grounding contacts.

11. The grounding connector of claim 1 , wherein the shell includes a cylindrical body at the mating end defining the cavity, an exterior of the cylindrical body being threaded.

12. The grounding connector of claim 1 , wherein the shell has a mounting flange at the mounting end having openings configured to receive fasteners.

13. The grounding connector of claim 1 , wherein the grounding contacts are machined contacts.

14. A grounding connector comprising:
a shell having a mating end at a front of the shell and a mounting end at a rear of the shell, the shell having a cylindrical body at the mating end defining a cavity open at the mating end configured to receive a mating component, an exterior of the cylindrical body being threaded, the shell having a base at the mounting end and a mounting flange extending from the base, the base having a plurality of contact channels open to the cavity, the base having a mounting surface; and
grounding contacts received in corresponding contact channels and entirely contained forward of the mounting surface, the grounding contacts having mating ends and compliant portions opposite the mating ends, the mating ends and the compliant portions forward of the mounting surface, the mating ends being positioned in the cavity for mating with the mating component, the compliant portions being received in the contact channels to mechanically and electrically connect each of the grounding contacts to the shell and to each other through the shell.

15. The grounding connector of claim 14 , wherein the compliant portions are directly supported by the shell and physically engage the shell to electrically connect to the shell.

16. The grounding connector of claim 14 , wherein the compliant portions are press-fit into the shell.

17. A grounding connector comprising:
a shell having a mating end at a front of the shell and a mounting end at a rear of the shell, the shell defining a cavity open at the mating end configured to receive a mating component, the shell having a base at the mounting end having a plurality of contact channels open to the cavity, the base having a mounting surface, the shell holding an interfacial seal in the cavity at the base, the interfacial seal having contact openings aligned with corresponding contact channels; and
grounding contacts received in corresponding contact channels and entirely contained forward of the mounting surface, the grounding contacts having mating ends and compliant portions opposite the mating ends, the mating ends and the compliant portions forward of the mounting surface, the mating ends extending forward of the base into the cavity for mating with the mating component, the mating ends passing through the contact openings in the interfacial seal such that the interfacial seal seals to each of the grounding contacts, the compliant portions being received in the contact channels to mechanically and electrically connect each of the grounding contacts to the shell and to each other through the shell.

18. The grounding connector of claim 17 , wherein the compliant portions are directly supported by the shell and physically engage the shell to electrically connect to the shell.

19. The grounding connector of claim 17 , wherein the compliant portions are press-fit into the shell.

20. The grounding connector of claim 1 , wherein the shell only holds grounding contacts and does not hold any signal contacts.
