Electrical connector assembly having means for EMI shielding

Claim 1

An electrical connector assembly including a generally cylindrical back shell of electrically conductive material and having an inner wall and a plurality of afterwardly extending first teeth, a cable having a center conductor encircled by a conductive braid received within and extending outwardly from said backshell, means including an accessory boot of an electrically conductive material for connecting the cable to the back shell, and means for shielding the center conductor against electro-magnetic interference, characterized by said means for shielding providing a continuous 360° electrically conductive seal around and between said back shell and the braid and comprising a ferrule of electrically conductive material connected to the braid in electric circuit relation and having its interior wall circumposing the center conductor, an outer sleeve of electrically conductive material in electrical circuit relation to said ferrule and having a forward axial end face, an inner sleeve of electrically conductive material having a rearward and a forward outer periphery with the outer diameter of each said periphery, respectively, being slightly greater than the inner diameter forming the interior wall of said outer sleeve and the inner wall of said back shell so as to interference fit therewithin and form a continuous 360° electrical seal therebetween, and an annular shoulder comprised of an electrically conductive, plastically deformable, material interposed between the forward axial end face of said ferrule and the first teeth of said back shell, said annular shoulder including a forward and a rearward end face with the rearward end face being adapted to plastically deform around the forward axial end face of the outer sleeve and the forward end face being adapted to plastically deform against said first teeth when compressed thereagainst to complete a continuous 360° electrically conductive seal.
