Problems solved by technology

[0003] However, in the process of dissipating the surge energy by heating, the temperature of the varistor sheet will rise
If the varistor continues to produce more heat than it dissipates, high temperature will be formed on the component, which will accelerate the deterioration of the varistor, eventually causing permanent damage, or even a fire, which will cause harm to users

Abstract

An integrated surge-absorbing device includes a surge-absorbing unit and a first external lead structure. The surge-absorbing unit includes a plurality of varistors stacked with together and a first metal lead, which is disposed between two of the neighboring varistors and has a first end protruding toward a first side edge of the varistors. A first end of the conductive rod of the first external lead structure is connecting to the first end of the first lead through a first low-melting-point metallic material. The first external lead structure applies a first resilient force to the first conductive rod.

Description

technical field [0001] The invention relates to a surge absorbing device, in particular to an integrated surge absorbing device with a plurality of varistor plates. Background technique [0002] In order to prevent the electronic components from being damaged by the instantaneous overvoltage surge of the power supply system, a surge absorbing protection circuit is usually installed in the electronic circuit. Surge absorbing protection circuits typically contain varistors that convert surge energy into heat. In detail, when the varistor is working, the current flows through the varistor, and the varistor will generate heat to relieve the surge and protect the circuit. [0003] However, in the process of dissipating the surge energy by heating, it will cause the temperature of the varistor sheet to rise. If the varistor continues to generate more heat than dissipate heat, high temperature will be formed on the component, which will accelerate the deterioration of the varisto...
