Electrical connector assembly having means for EMI shielding
First Claim
1. An electrical connector 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 received within and extending outwardly 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, characterized by said means for shielding providing a continuous 360°
- electrically conductive seal between the conductive braid and said back shell and comprising a ferrule of electrically conductive material in electrical circuit relation to the cable braid and a sleeve of electrically conductive material in electrical circuit relation to said braid and said ferrule and having a frusto-conical annular wall portion thereof overlapping and completely encircling the back shell, the diameter of said annular wall portion having a dimension sized to interference fit relative to the back shell at a location spaced longitudinally inward from its transverse end face whereby said annular wall portion completes a continuous electrical seal and circuit path around and between the back shell.

Abstract
A continuous 360° electrically conductive seal about the back shell (30) of an electrically conductive connector shell (20) having teeth extending aftwardly from its end face (34) and around the braid shield (46) of a coaxial-type cable (40) connected to the back shell by an accessory boot (50) protects signal carrying conductors from EMI entry and the surrounding area from EMI leakage. A frusto-conical wall including an electrically conductive annular wall portion, such as provided by the inner wall (100) of an accessory ferrule (56), or of an electrically conductive annular cap (68, 78, 86) mounted in the ferrule is interference fit about the toothed end face of the connector shell so as to overlap and completely encircle the back shell at a point inwardly of the valleys (36) of the teeth.
