Abstract
A shielding and grounding ring comprises a cup shaped member including a flat ring portion defining the base of the cup and having a central opening sized to fit about a plug shell, a skirt described by a plurality of slots and associated fingers each extending longitudinally from the end of the skirt to locations on the ring portion, and a circumferential lip extending rearwardly from the opening. When a compression ring is plastically deformed in the groove, the lip and the ring portion, respectively, make substantially 360.degree. contact with the annular groove and the radial flange thereby providing positive retention and completing electrical circuit paths with the plug shell. The slots undergo a 90.degree. change in direction to reduce adverse stress which could lead to spring finger failures in the ring.
