    摘要: The present invention provides a protection device including a bimetal component and a PTC component. This protection device includes a resin base, a first terminal, a second terminal, a PTC component, a bimetal component, an arm, an upper plate and a resin cover. A portion of the first terminal configures a first electrode, and a portion of a second terminal configures the second electrode, and the first electrode and the second electrode are exposed outward at the bottom surface of the resin base. In a normal state, the first terminal, the arm and the second terminal are electrically connected in series. When the bimetal component is activated, the first terminal and the arm become electrically cut off while the first terminal, the PTC component, the bimetal component, the arm and the second terminal are electrically connected in series in the mentioned order.

    摘要: The present invention provides a protection device which includes a laminar element 16 which is formed of an insulation resin and has at least one throughhole; electrically conductive metal thin layers 22 and 28 which are positioned on each of main surfaces of the laminar element, and a fuse layer 40 which is positioned on a side surface defining said at least one throughhole and electrically connects the electrically conductive metal thin layers. The fuse layer includes a first metal layer 41 consisting of a metal having a higher melting point and a second metal layer 42 consisting of a metal having a lower melting point. The protection device of the present invention allows a larger amount of a current to flow therethrough and can provide a protection from an excessive current.
