| 发明名称 | Protection circuit | ||
| 摘要 | A protection circuit includes a surge absorber, a switch device electrically connected to the surge absorber and having a first conductor and a second conductor, and a heat-shrinkable device disposed on an outer periphery of the surge absorber and shrinking in accordance with temperature of the surge absorber. The first conductor has a first connecting portion and a second connecting portion. The surge absorber is connected to the first connecting portion. When the switch device is in an initial state, the second connecting portion electrically contacts the second conductor, and when the heat-shrinkable device shrinks to separate the second connecting portion from the second conductor, the switch device is switched off. | ||

| 主权项 | 1. A protection circuit, comprising: a surge absorber; a switch device electrically connected to the surge absorber and having a first conductor and a second conductor, wherein the first conductor has an end having a first connecting portion and a second connecting portion; a heat-shrinkable device disposed on an outer periphery of the surge absorber, connected to the first connecting portion and shrinking in accordance with a temperature of the surge absorber, wherein when the switch device is in an initial state, the second connecting portion electrically contacts the second conductor, and when the heat-shrinkable device shrinks, the first connecting portion of the first conductor is moved by a shrinkage of the heat-shrinkable device, and the second connecting portion is separated from the second conductor, causing the switch device to be switched off. | ||
