ABSTRACT:
The present invention relates to a grounding ring which may be used in grd adapters. The grounding ring has a structure resembling a miniature box girder with an irregular hexagonal cross section and is bent into a toroidal configuration. The grounding ring is characterized by increased wall areas for establishing electrical contact between a surface of a conductor and a surface of a stuffing tube, grounding conduit, or shield grounding fitting. The grounding ring provides improved EM performance and better capacitive coupling.
