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： A thermal cut-off device includes a plastic base, two electrodes, a temperature sensing element, and a plastic cover that fits over the base. The temperature sensing element is curved downward, and may be a bimetal or a trimetal. When the device is subject to an over-temperature condition, the orientation of the curve flips such that the temperature sensing element is then curved upward. When the temperature sensing element is curved upward, it lifts an arm of one of the electrodes, which severs the electrical connection between the electrodes. In this manner the device shuts off during an over-temperature condition in order to protect the circuit in which the device is installed. To prevent corrosion of the temperature sensing element, a first moisture insulation layer is applied to the outer surface of the thermal cut-off device. The moisture insulation layer may be an epoxy adhesive or a UV/visible light-cured adhesive or light/heat cured adhesive. In some embodiments, a second moisture insulation layer is formed on the surface of the temperature sensing element.

摘要： The present invention provides a protection device which includes a PTC component and a first non-resettable contact component which is connected electrically in parallel to the PTC component. A second non-resettable contact component is connected electrically in series to the PTC component, and when the PTC component is tripped by a current which is diverted by opening the contact of the first non-resettable contact component, the contact of the second non-resettable contact component opens due to heat which is generated by the PTC component.
