Electrical connector assembly having means for EMI shielding
First Claim
1. An electrical connector assembly including means for shielding against electro-magnetic interference, the assembly comprising a shell of electrically conductive material including a generally cylindrical back shell having a transverse end face, a cable having a center conductor encircled by a conductive braid shield and received within and extending rearwardly from said back shell, 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, said shield means characterized by a continuous 360°
- electrically conductive seal between the cable braid and said back shell and comprising a ferrule of electrically conductive material being electrically connected to the braid, and a cylindrical sleeve of electrically conductive, plastically deformable material being in electrical circuit relation with the ferrule and the back shell, the sleeve having a forward sleeve portion thereof plastically deformed around and longitudinally forward from the transverse end face of the back shell to provide a continuous electrically conductive seal therearound.

Abstract
A cylindrical sleeve (66) of electrically conductive, plastically deformable, material completes an electrical circuit path between the braid (46) of a cable (40) terminated to a back shell (30), the braid connected electrically to a ferrule (56), and the sleeve having a forward sleeve portion extending from an annular groove (62) of the ferrule and plastically deformed about the toothed end face (34) of the back shell (30) so as to axially overlap and completely cover the teeth and form a 360° electrically conductive seal about the back shell at a location inwardly of the valleys (36) forming the teeth.

4. A method for shielding an electrical connector assembly against electro-magnetic interference, the assembly including a back shell of electrically conductive material, a cable having a center conductor encircled by a conductive braid shield, a ferrule of electrically conductive material in electrical circuit relation to the braid, and means including a rotatably disposed retaining nut for connecting the cable to the back shell, the steps of the method characterized by:
-
mounting a sleeve of electrically conductive material onto said ferrule so that an electrically conductive seal is formed between said sleeve and said ferrule and so that said sleeve has a forward sleeve portion thereof confronting a transverse end face of the back shell, terminating the cable to the assembly, the termination passing the center conductor into the back shell and the ferrule between the braid shield and the center conductor, and moving said ferrule towards and against the transverse end face of said back shell in an amount sufficient to plastically deform the forward sleeve portion around the back shell and cause the forward sleeve portion thereof, to overlap and completely encircle the back shell in an electrically conductive seal. - View Dependent Claims (5)
