ABSTRACT:
A substantially continuous "bracelet-like" grounding and electromagnetic shielding device for placement in a circumferential cavity formed by an annular groove in at least one of two overlapping body portions of mating electrical connector subassemblies. The device is formed as a flat stamping and curved into a "bracelet" shape with closely interleaving first and second axially extending flat fingers. A base portion in the form of a ring extending about the circumference of the groove and having a first set of substantially flat, integral, axially-extending fingers spaced circumferentially and occupying substantially the entire axial dimension of the cavity. A second set of similar fingers also integral with the base ring is folded against a surface of the base ring so as to extend in the same axial direction as the first finger set, the fingers of the first and second being tightly interleaved circumferentially and bowed radially outward at an axially intermediate point to facilitate electrical bonding between the mated connector subassemblies.
