Abstract
A fiber cutter includes: a base including a fiber grip that grips an optical fiber; a slider including a fiber end grip that grips an end portion of the optical fiber, wherein the slider moves relative to the base; a cut former including a blade forming an initial cut in the optical fiber and disposed between the fiber grip and the fiber end grip; and a spring that applies a force between the base and the slider to apply a tension to the optical fiber gripped by the fiber grip and the fiber end grip, wherein the cut former is disposed on the slide, and when the initial cut grows and the optical fiber cleaves, the cut former moves together with the slider by the force of the spring.
Claims6
A fiber cutter comprising:
- a base comprising a fiber grip for gripping an optical fiber;
- a slider comprising a fiber end grip for gripping an end portion of the optical fiber, wherein the slider is movable relative to the base;
- a cut former comprising a blade for forming an initial cut in the optical fiber, wherein the cut former is disposed between the fiber grip and the fiber end grip;
- a spring that applies a force between the base and the slider for applying tension to the gripped optical fiber;
- a latch unit that engages the base and the slider;
- and
- a pressing body that releases the latch unit, wherein
- the cut former is disposed on the slider, the pressing body moves the cut former to form the initial cut,
- when the blade comes close to the optical fiber in order to form the initial cut in the optical fiber, the pressing body releases the latch unit and the spring applies the tension to the optical fiber, and
- when the initial cut grows such that the optical fiber is cut through, the cut former moves relative to the pressing body and together with the slider by the force of the spring.
