Abstract
Description
Technical Field
[0001] The utility model relates to the field of fusion splicers, in particular to a split heating device for an optical fiber fusion splicer. Background Art
[0002] Fiber fusion splicers generally work on optical fibers and optical cables. Generally, they generate high-voltage arcs through electrodes to merge two optical fibers into one for use, so they are also called optical cable fusion splicers. The main function of fusion splicers is to facilitate the maintenance and emergency repair of optical fiber and cable lines. Since it is difficult to perform fusion splicing on optical fibers with the naked eye, the operation of fiber fusion splicers is very dependent on the lens inside the fiber fusion splicer. Through the lens, the fusion process and fusion effect of the optical fiber can be observed more intuitively and clearly.
[0003] When the two optical fibers are welded, the heat shrink tube needs to be put on the connection position, and then the heating device on the optical fiber fusion splicer is used to heat the heat shrink tube so that the heat shrink tube tightly covers the connection between the two groups of optical fibers. When the heat shrink tube is heated, the outside of the heat shrink tube cannot be heated evenly, so that the heat shrink tube cannot be evenly shrunk. At the same time, after the heat shrinkage, the heat shrink tube needs to be naturally cooled, which greatly reduces the connection efficiency of the optical fibers. Utility Model Content
