Small -size fuse

The utility model provides a small -size fuse, but includes mount the fuse -element in both ends forms open tube, and the both ends cooperation of tube has the end cap, but the fuse -element lie in between the both ends cap of tube through welding on the soldering tin in the end cap, fusible external side cover is equipped with the sleeve pipe. The sleeve pipe is silicone tube. The utility model discloses an it strengthens the arc extinguishing ability and reduces the impact force that explodes to increase the sheathed tube mode on the fuse -link to put forward the high -breaking ability. 种小型熔断器，包括在两端形成敞口的管壳中架置可熔体，管壳的两端配合有端帽，可熔体通过焊接于端帽中的焊锡上而位于管壳的两端帽之间，可熔体外侧套设有套管。套管为硅胶套管。本实用新型通过在熔断体上增加套管的方式来增强灭弧能力并减小爆炸冲击力，从而提高分断能力。
