Abstract
An optical fiber cutter includes a main body including a fiber fixing portion, and a moving portion including a blade for scratching the optical fiber, the moving portion being attached to the main body to be movable between a first position and a second position, the first position being an initial position before the optical fiber is scratched, the second position being a position after the optical fiber is scratched. The fiber fixing portion is configured to move the optical fiber such that the optical fiber fixed to the fiber fixing portion does not cross a movement range when the blade portion moves from the second position to the first position, and such that a cleaved surface of the optical fiber after cleaving is positioned in a direction away from the blade portion along an axial direction of the optical fiber.
Claims3
An optical fiber cutter for cleaving an optical fiber, the optical fiber cutter comprising:
- a main body including a fiber fixing portion, the fiber fixing portion configured to change a position of the optical fiber;
- a moving portion including a blade for scratching the optical fiber, the moving portion being attached to the main body to be movable between a first position and a second position, the first position being an initial position before the optical fiber is scratched, the second position being a position after the optical fiber is scratched;
- and
- a first biasing member configured to bias the fiber fixing portion toward the blade,
- wherein when the moving portion moves from the first position to the second position, the fiber fixing portion is biased by the first biasing member to be positioned on the blade, and
- when the moving portion moves from the second position to the first position, the fiber fixing portion moves in a direction away from the blade against a biasing force of the first biasing member,
- wherein the moving portion includes:
- a rotatable cam;
- and
- a second biasing member configured to bias the cam such that the cam rotates in a direction in which the cam protrudes toward the fiber fixing portion, and
- wherein when the moving portion moves from the first position to the second position, the cam rotates in a direction in which the cam does not protrude toward the fiber fixing portion against a biasing force of the second biasing member, and
- when the moving portion moves from the second position to the first position, the cam protrudes toward the fiber fixing portion by being biased by the second biasing member.
