Description

Technical Field

[0001] The utility model relates to the field of fusion splicers, in particular to a heat insulation device for a heater of 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 welding of two optical fiber cables is completed, the heat shrink tube needs to be put on the connection position, and then the heater 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, no heat insulation structure is set on the heater, which causes the heat generated by the heater to dissipate from the openings on both sides of the heating for accommodating the optical fiber cables, resulting in a large amount of heat loss. The heater needs to be heated continuously to replenish the lost heat, consuming a large amount of power from the lithium battery and reducing the battery life of the fusion splicer.
