Abstract
A ceramic ferrule assembly is provided, including a head including at least one tab protruding outwardly from an inner peripheral surface thereof, and a stem having an annular flange about an outer peripheral surface thereof and having at least one slot formed therein, the slot being adapted to receive the tab and retain the tab in a stationary position when the stem is rotated relative the head, whereby the at least one tab and the at least one slot mechanically engage one another to secure the ferrule stem and ferrule head to prevent axial disassociation from one another without counter rotation.
Claims20
A ceramic ferrule assembly comprising:
- a ferrule head comprising at least one tab protruding outwardly from an inner peripheral surface thereof;
- and
- a ferrule stem comprising an annular flange about an outer peripheral surface thereof and having at least one slot formed therein, said slot being adapted to receive said tab and retain said tab in a stationary position when said ferrule stem is rotated relative said ferrule head;
- whereby said at least one tab and said at least one slot to secure said ferrule stem and said ferrule head to prevent axial and radial disassociation from one another without counter rotation.
A ceramic ferrule assembly comprising:
- a ferrule head having a hexagonal outer peripheral shape and extending from a first end to an opposed second end thereof defining a length thereof, said ferrule head having a central bore extending along said length thereof, and defining a longitudinal extension axis thereof, from a hexagonal opening at said first end of said ferrule head to a circular opening at said second end of said head, said central bore having an inner peripheral surface defined by a first section having a tapered hexagonal shape extending from said first hexagonal opening to an annular ridge, and a second section having a cylindrical shape extending from said annular ridge to said circular opening, and said ferrule head having at least one tab extending from a portion of said inner peripheral of said central bore of ferrule head;
- and
- a ferrule stem extending from a first end toward an opposed second end in a longitudinal extension direction defining a length thereof, and having a first radial flange spaced a distance away from said second end of said ferrule stem along the longitudinal extension direction of said ferrule stem and having a slot formed therein, and a second radial flange located proximate and defining said second end of said ferrule stem;
- wherein said at least one tab of said ferrule head resides in a portion of said at least one slot in a rotatably engaged position, mechanically securing said ferrule stem to said ferrule head to prevent axial and radial disassociation without counter rotation;
- and
- wherein said second flange of said ferrule stem is seated on said annular ridge of said inner peripheral surface of said ferrule head.
