Core adjusting bracket

Abstract

The invention provides a core adjusting bracket comprising a housing, at least one adjusting assembly and at least one fiber positioning block. At least one adjusting hole is formed in the housing. The elastic member of the adjusting assembly is provided with a through hole at the position corresponding to the adjusting hole of the housing. An independent swing rod extends from the surface of theelastic member to the upper side of the through hole. A transmission rod penetrates the through hole of the elastic member and the corresponding adjusting hole of the housing. The lower end of the transmission rod extends out of the lower side of the adjusting hole. A steel ball is placed between the upper end of the transmission rod and the end portion of the swing rod. The fiber positioning block is fixed to the upper end of the corresponding swing rod. The upper end surface of the fiber positioning block is provided with a stopping groove for placing an optical fiber. According to the relative positions of the end surfaces of two optical fibers placed in the two fiber positioning blocks, an external mechanism is controlled to have an effect on the lower end of the transmission rod suchthat the transmission rod drives the steel ball at the upper part to move. Thus, the swing rod of the elastic member can swing relative to the body of the elastic member. The end surfaces of the two optical fibers placed in the stopping groove can be aligned to each other and a welding fusion requirement is satified.

Description

technical field [0001] The invention relates to a bracket, in particular to a core-adjusting bracket used in an optical fiber fusion splicer. Background technique [0002] The alignment bracket is an important part of the optical fiber fusion splicer. Its function is to limit the position of the two optical fibers before the optical fiber welding, to ensure that the end faces of the two optical fibers are aligned with each other, and to ensure the accuracy of welding. Most of the existing alignment brackets are Fixed alignment bracket, the alignment bracket cannot be moved, but the optical fiber is placed behind the fiber positioning block, the problem of misalignment of the end face is prone to occur, and manual adjustment is required. Because the optical fiber is thin, the end face alignment is cumbersome, time-consuming and laborious. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a core-adjusting bracket cap...
