The invention discloses a multi-core ribbon-shaped optical fiber clamp with self-locking and anti-slip function, which is composed of a ribbon-fiber limiting device, a clamping device, a transmission device, a self-locking circular eccentric wheel and other parts, and belongs to the technical field of ribbon-shaped optical fiber. The push plate of the transmission device of the present invention can rotate around the central push plate pin, so that the force on the clamped part of the ribbon fiber is uniform, and the damage to the outer coating layer is avoided; the rotation angle of the self-locking circular eccentric wheel can be adjusted to realize different clamping for the optical fiber. The clamping force can fix the ribbon fiber when the overall force of the ribbon fiber or the scattered force of each optical fiber in the ribbon fiber is applied. It has a self-locking function to keep the force constant after the ribbon fiber is clamped; adjust the width of the ribbon fiber limit device to maintain The plate can limit the ribbon fibers with different core numbers, and has good versatility; the whole device has a simple and reliable structure, and is easy to operate, and can effectively clamp the ribbon fibers composed of single fibers that bear a tensile force below 5N. It is suitable for Mass production of ribbon fiber array gratings, etc.
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...
