Abstract
An explosion-proof and flameproof ejection type safety surge-absorbing module includes a protective member and a surge-absorbing unit. The protective member includes a base and an upper lid coupled with the base. The base has two corresponding partitions extending upwards. The surge-absorbing unit includes a body, two connecting leads, and a resilient metallic plate. The body has two sides defining two electrode surfaces. One of the electrode surfaces is connected with one of the connecting leads. The resilient metallic plate has a first end welded to the electrode surface with a contact component and a second end curved and striding across an outer side of one of the partitions to penetrate through the bottom of the base. When the body of the surge-absorbing unit is overheated due to high temperature caused by a surge, the contact component will melt so the resilient metallic plate is ejected away from the electrode.
