  • External cable grommet for cable entry of EMI protected cabinets
    Patent number: 5170008
    Abstract: A grommet provides a surrounding conductive elastomer connection to a stripped portion of an external cable shield. The cable is inserted through the central passage of the grommet and placed in a U-shaped opening in an enclosure frame. The open side of the U is closed with another metal member to complete a 360 degree termination around the shield. A one piece metal band within the grommet provides a direct low resistance path from the cable shield to the enclosure frame. The band has an interference fit in the outer groove of the grommet and utilizes the elasticity of the grommet to hold the band in place.
