INTEGRATED SURGE-ABSORBING DEVICE

摘要

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.

1. An integrated surge-absorbing device, comprising:
a surge-absorbing unit, comprising a first varistor and a second varistor arranged together in a stack, wherein a first lead is disposed between the first varistor and the second varistor, and a first end of the first lead protrudes toward a first side of the surge-absorbing unit; and a first external lead structure, disposed on the first side of the surge-absorbing unit and comprises a first conductive rod, wherein a first end of the first conductive rod is electrically connected to the first end of the first lead through a first low-melting-point metallic material, and the first external lead structure applies a first resilient force to the first conductive rod;
wherein the first external lead structure cuts off the connection between the first conductive rod and the first lead when the first low-melting-point metallic material melts.
