Multi-core belt-shaped optical fiber fixture with self-locking and anti-skidding function

Abstract

The invention discloses a multi-core belt-shaped optical fiber fixture with a self-locking and anti-skidding function. The multi-core belt-shaped optical fiber fixture with the self-locking and anti-skidding function comprises a belt-shaped optical fiber limiting device, a clamping device, a transmission device, a self-locking round eccentric wheel and the like, and belongs to the technical field of belt-shaped optical fibers. A push plate of the transmission device can rotate around a central push plate pin to ensure that clamped portions of the belt-shaped optical fibers are evenly stressed, and damage of an outer coating layer is avoided; by adjusting rotating angles of the self-locking round eccentric wheel, different clamping force of the fixture to the optical fibers can be achieved, the belt-shaped optical fibers can be fixed under the conditions that the belt-shaped optical fibers are overall stressed or each belt-shaped optical fiber is dispersedly stressed, the self-locking function is placed, after being clamped, the belt-shaped optical fibers are constantly stressed, by adjusting a width maintaining plate of the belt-shaped optical fiber limiting device, the belt-shaped optical fibers with different numbers of cores can be limited, and the fixture is good in generality. The whole device is simple and reliable in structure, convenient to operate, capable of effectively and stably clamping the belt-shaped optical fibers composed of each single fiber capable of bearing drawing force of lower than five Newton, and applicable for aspects like mass production of belt-shaped optical fiber array optical gratings.

Description

technical field [0001] The invention relates to optical fibers, in particular to a multi-core ribbon-shaped optical fiber clamp. Background technique [0002] Ribbon optical fiber is an important optical component, with high fiber density, it can accommodate more fiber cores under the same outer diameter of the optical cable; the connection is simple and convenient, and multiple optical fibers can be connected at the same time, saving installation time and cost. Fiber array gratings are gratings with the same or different central wavelengths prepared on each fiber of the ribbon, and have great application potential in the fields of optical fiber communication and optical fiber sensing. [0003] At present, the phase mask UV exposure method has been widely used in the preparation of fiber gratings, including uniform, apodized, chirped and sampled gratings. The phase mask method is simple to operate, but it has high requirements on the stability of the optical fiber during th...
