摘要： A method of connecting a ferrule to an optical fiber polishing fixture assembly comprises obtaining a fixture base to which a clamping assembly is operatively connected, positioning a lever in an unlocked position thereby creating a gap between first and second base portions, obtaining a fiber optic connector and cable assembly including a ferrule operatively connected to a cable, positioning the ferrule in a ferrule bore, and moving the lever from the unlocked position to a locked position thereby causing the first and second base portions to engage the fiber optic connector and cable assembly.

摘要： An optical fiber polishing fixture assembly comprises a fixture base and a clamping assembly. The clamping assembly has first and second base portions, a lever, and a biasing member. Each of the first and second base portions has an inner facing side with a slot and an inner facing surface. The slots are adapted to receive bars on opposing sides of a fiber optic connector and cable assembly. The lever has a first end positioned between the inner facing surfaces and a second end extending outward therefrom. The clamping assembly has a locked position, when the first and second base portions are biased toward one another by the biasing member, and an unlocked position, when the lever overcomes a biasing force of the biasing member and separates the first and second base portions.

摘要： A toolless clamp comprises a shaft, a base, a latch, a first biasing member, and a clamping member. The base has a base bore configured and arranged to slidably receive a portion of the shaft. The latch has a latch bore configured and arranged to slidably receive a portion of the shaft and a portion of the base. The first biasing member is configured and arranged to bias the latch in a first direction away from the clamping member in an unclamped position and bias the shaft and clamping member in a second direction toward the base in a clamped position. The clamping member is operatively connected to a proximal end of the shaft and is configured and arranged to disengage the connecting member when the latch is in the unclamped position and engage the connecting member when the latch is in the clamped position.

摘要： An optical fiber polishing arm positioning assembly for use with an optical fiber polisher, the optical fiber polisher including a first pivot connection interconnecting a base and a proximal end of an arm assembly, comprises a positioning member and an actuator. The positioning member is configured and arranged to be operatively connected to the arm assembly, and the actuator is configured and arranged to move the positioning member thereby moving the arm assembly about the first pivot connection to vary positions of the arm assembly relative to the base.

摘要： A polishing fixture assembly comprises a fixture base, which has a ferrule aperture and a spring member, and a clamping assembly. The spring member comprises upper, middle, and lower springs. The upper spring forms a portion of a cam aperture. The middle spring is proximate the ferrule aperture. The clamping assembly has a clamp base, a lever, and a cam shaft. The clamp base is connected to the fixture base. The lever is pivotally connected to the clamp base and has unlocked and locked positions. The cam shaft is connected to the lever and rotates within the cam aperture when the lever pivots. As the lever is moved into the locked position, the cam shaft rotates, opposing narrower sides of the cam shaft contact the upper spring thereby flexing the middle spring and the lower spring so that the middle spring contacts a ferrule positioned in the ferrule aperture.
