  • Slotted grounding ferrule
    Patent number: 5051543
    Abstract: A grounding ferrule is characterized by a generally cylindrical hollow member having at least three equiangularly circumferentially spaced axially extending slots which cooperate to define a plurality of circumferentially adjacent webs. Each web has a plurality of radially inwardly extending protrusions provided on the inner surface thereof. The ferrule responds to a radially inwardly directed crimping force applied circumferentially to the exterior surface of the webs by deflecting radially inwardly to define a constricted central region.
