Electrical connector grounding ring
First Claim
Patent Images
1. An electrical connector member comprising:
- a first shell surrounding an insulator adapted to contain electrical contacts, said shell having a forward end;
a peripherally continuous, single-layer annular ring mounted on said shell;
the wall of said ring, in longitudinal section, having a generally C-shaped configuration with opposite ends and a middle, and with the convex surface thereof facing forwardly of said shell;
said ring embodying a radially resilient free-end contacting portion;
said contacting portion of said ring resiliently deflecting radially when the connector member is mated with a second connector member having a second shell which telescopically engages with said contacting portion;
said C-shaped ring surrounding said forward end of said first shell so one end of said C-shaped configuration lies on the radially outer side of said shell and the other end of said C-shaped configuration lies on the radially inner side of said shell.

Abstract
An electrical connector in which one connector member contains a grounding ring having a wall of "C"-shaped configuration in longitudinal section. When the mating halves of the connector are interengaged, the shell of the other connector member slides into the grounding ring deflecting the inner peripheral wall thereof outwardly. The ring provides a windowless EMI/RFI grounding shield for the connector.

2. An electrical connector comprising:
-
first and second mating connector members each including a shell with a forward end that can telescope into the forward end of the other, said first shell having a larger forward end than said second shell; a peripherally continuous, single-layer annular ring mounted on said first shell; the wall of said ring, in longitudinal section, having a generally C-shaped configuration with the convex surface thereof facing forwardly toward the other of said shells, said C-shaped configuration forming a radially outer portion mounted on said first shell member; said ring embodying a radially free inner contacting portion extending inwardly of said first shell forward end, said contacting portion having a tip which lies radially inwardly of all other portions of the ring; said second shell telescopically engaging with said contacting portion of said ring when said connector members are mated causing said contacting portion to resiliently deflect radially to thereby provide a firm connection between said shells. - View Dependent Claims (3)

4. An electrical connector member comprising:
-
a first shell surrounding an insulator adapted to contain electrical contacts; a peripherally continuous, single-layer annular ring mounted on said shell; the wall of said ring, in longitudinal section, having a generally C-shaped configuration with the convex surface thereof facing forwardly of said shell; said ring embodying a radially resilient free-end contacting portion; said contacting portion of said ring resiliently deflecting radially when the connector member is mated with a second connector member having a shell which telescopically engages with said contacting portion; said first shell having a shallow groove rearward of a forward shell portion and said ring having a mounting ring flange opposite said contacting portion, that has an interference fit with said forward portion of the shell that lies forward of said groove, said interference fit being small enough that the mounting ring flange can be forced past the forward shell portion into the groove without destroying either the flange or the shell.
