Abstract: AN ELECTRICAL CONNECTOR ASSEMBLY HAVING MEANS FOR SHIELDING ELECTROMAGNETIC INTERFERENCE A closed, radially contractible, metallic annular spring band (20) is radially interposed between mating plug and receptacle shells (10, 40) to shield electromagnetic signals from entering or leaving the assembly, the plug shell (10) including an annular groove (14) circumposed by annular lips (16, 18) which define annular undercuts (17, 19) therearound to receive and captivate the spring band contracted therein. The spring band includes flat margins (22) which extend into the undercuts, an arcuate section (24) between the margins having an arcuate cross-section which extends radially upward from the annular groove a distance sufficient to be compressed by the receptacle shell during mating, and a plurality of alternating slots (26) opening along opposite edges (21, 23) thereof to define alternating segments (28) which overlappingly fold over one on to the other to close the slots (26) when the band (20) is contracted, the band initially being of greater diameter than the plug (10) and the arcuate section (24) being adapted to radially flatten during mating.
