Abstract

The invention discloses a closed type elastic core regulation mechanism which comprises a support, an ejector rod and an elastic body. The elastic body is installed on the top of the support. The closed type elastic core regulation mechanism is characterized in that a deformation cavity and a deformation groove are formed in the elastic body, the deformation cavity is a hollow cavity formed in the upper portion in the elastic body, the deformation groove is formed below the deformation cavity, the deformation cavity and the deformation groove are separated through a supporting wall, the ejector rod is arranged in the elastic body, and the bottom of the elastic body extends upwards and points to the deformation cavity. Compared with the prior art, the closed type elastic core regulation mechanism has the advantages that the problem of fine alignment of a left optical fiber and a right optical fiber which need to be welded is solved, machining is facilitated, the machining difficulty is lowered, and the manufacturing cost is low; meanwhile, the regulation accuracy and amplitude can be taken into consideration for the core regulation mechanism at the same time through the combination of the deformation cavity and the deformation groove, the regulation process is stable and reliable, and stability is good.

Description

technical field [0001] The invention relates to the technical field of optical fiber fusion, and in particular relates to an elastic core-adjusting mechanism for fine alignment of optical fibers. Background technique [0002] Optical fiber fusion splicer is mainly used for the construction and maintenance of optical cables in optical communication, so it is also called optical cable fusion splicer. The general working principle is to use a high-voltage arc to melt the sections of the two optical fibers, and at the same time use a high-precision motion mechanism to gently advance the two optical fibers into one, so as to realize the coupling of the optical fiber mode field. [0003] Optical fiber fusion splicer includes optical fiber guide and alignment mechanism. The system stability of the fiber alignment mechanism is the basis for the stability of the fiber splicing index. Most of the existing centering elastic mechanisms of fusion splicers have problems such as large st...
