摘要： The present invention discloses a thermal fuse having dual metal elastic clamps, comprising: an insulating cylindrical tube; a first metal cap, a temperature sensing chamber formed by the first metal cap, the second metal tube and the inner side wall of the middle part of the through hole. The temperature sensing chamber axially arranges a plurality of components in the following sequence: a compressed spring; an insulating supporting pillar; a second metal elastic clamp; a connecting pillar a first metal elastic clamp; an organic temperature sensing body capable of melting when heating. The first metal elastic clamp, the second metal elastic clamp and the connecting pillar forms a movable conductive bridge. The movable conductive bridge slides flexibly in the temperature sensing chamber and has low contacting resistance with the first metal cap and the second metal tube. The above structure can withstand large current and has high reliability.
