Abstract An EMI shielded connector assembly for a cable connector is formed of aluminum and has an aperture 44 therein to receive potting compound 46 to secure the wires 28 to the connector body. The braided inner cover 26 of the cable 24 is formed into a pig tail 34 and is secured in the back-shell 40 by the potting compound 46. Between the braided inner cover 26 and the braided outer cover 30 which is the braided shield, a ferrule member 60 is positioned on the cable and the outer cover 30 is braided over the ferrule member 60. Next the ferrule clamping member 62 is positioned over the ferrule member 60 in such a position that the groove 68 overrides the ring 66. The two ferrule member 60 and 62 are pressed together and form a strain relief means 38. The strain relief means 38 is welded 42 to the back-shell 40 and a rivet 48 plugs the potting aperture 44 in the back-shell 40 after which a rubberized boot 50 is formed over the enclosure. Prior to forming the boot 50, the back-shell 40 is staked or secured to the connector body. The result is a solid, secure EMI shielded enclosure for a cable connector and operates with either a straight or elbow back-shell 40.
An EMI shielded connector assembly comprising a cable connector body, a cable having at least a first cover overlying jacketed wires and terminating in a braided tail, a second braided cover overlying the first cover, the jacketed wires extending beyond the first and second covers and inserted in the connector body; and a back-shell receiving the cable at one end and pressed fit to the connector body at the other end, the back-shell having an aperture therein adapted to receive potting compound within the shell; characterized by a ferrule member encircling the cable between the first cover and the second cover; a ferrule clamping member compressing the second cover to said ferrule member forming an interference fit; means securing said ferrule clamping member to the back-shell; potting compound filling the interior of the back-shell and securing the tail of the first cover and the jackets of the wires therein; and means closing the aperture and with the back-shell and said ferrule clamping member forming an EMI shield over the cable and connector body.
