Abstract
An explosion-proof and flameproof pullout safety surge-absorbing module includes a surge-absorbing unit, a protective unit, a function member, and a hot melt component. The unit has a body defining an electrode side. The middle section of electrode side defines a partially exposed electrode side further connected to a first pin. The protective component includes a base and a top cover conjoint to the base. The body is between the base and the top cover. The function member includes a recovery component and a function part. The recovery component is flexible, of which one terminal connects the base and the other terminal connects the function part pivoting onto the base and working in a first state and a second state. In the first state, one terminal of the function part is connected to the partially exposed electrode side; in the second state, the hot melt component is heated and melt.
