1. A combination shielding and grounding device formed from resilient conductive sheet material for installation in an annular groove of predetermined axial dimension within overlapping conductive body portions of a pair of mating electrical connector subassemblies, comprising:

  • a ring portion adapted to extend substantially continuously about the circumference of said groove, said ring portion having an axial dimension less than said groove axial dimension, said ring portion having opposite edges;

    a first set of spaced fingers integral with one of said edges of said ring portion and extending axially therefrom; and

    a second set of spaced fingers integral with the other of said edges of said ring portion and folded substantially 180°

    against said ring portion so as to extend axially in the same direction as said fingers of said first set, said fingers of said first set being spaced apart a distance only slightly greater than the width of the fingers of said second set, said first and second finger sets interleaving to minimize the circumferential clearance between adjacent fingers to form a continuous bracelet, said fingers being bowed in axial cross-section whereby the fingers are adapted to contact radially opposite surfaces of said body portions of said mating electrical connector subassemblies.
